It appears that APPs represent appropriate analytes for assessment of animal health. Whereas they represent non-specific markers as biological effect reactants, they can be used for assessing nutritional deficits and reactive processes, especially when positive and negative acute phase variables are combined in an index. When such acute phase index is applied to separate healthy animals from animals with some disease, much better results are obtained than with single analytes and statistically acceptable results for culling individual animals may be reached. Unfortunately at present no cheap, comprehensive and easy to use system is available for assessing various acute phase proteins in serum or blood samples at the same time. Protein microarray or fluid phase microchip technology may satisfy this need; and permit simultaneous analysis of numerous analytes in the same small volume sample and enable integration of information derived from systemic reactivity and nutrition with disease specific variables. Applying such technology may help to solve health problems in various countries not only in animal husbandry but also in human populations.展开更多

However, few studies have examined the relationship between time of acupuncture and curative effect on cerebral hemorrhage. By observing the effect of acupuncture on changes in histopathology, ultrastructure, and neuroethology in a cerebral hemorrhage model of rats, we have directly examined the time-effect relationship of acupuncture. The rat model of cerebral hemorrhage was produced by slowly injecting autologous blood to the right caudate nucleus. The experimental groups were: 3-, 9-, 24-, and 48-hour model groups; and 3-, 9-, 24-, and 48-hour acupuncture groups. The sham-operation group was used for comparison. Acupuncture was performed at the Neiguan(PC6) and Renzhong(DU26) acupoints, twice a day, 6 hours apart, for 5 consecutive days. Brain tissue changes were observed by light microscopy and transmission electron microscopy. Neuroethology was assessed using Bederson and Longa scores. Our results show that compared with the sham-operation and model groups, Bederson and Longa scores were lower in each acupuncture group, with visibly improved histopathology and brain tissue ultrastructure. Further, the results were better in the 3-and 9-hour acupuncture groups than the 24-and 48-hour acupuncture groups. Our findings show that acupuncture treatment can relieve pathological and ultrastructural deterioration and neurological impairment caused by the acute phase of cerebral hemorrhage, and may protect brain tissue during this period. In addition, earlier acupuncture intervention following cerebral hemorrhage(by 3 or 9 hours) is associated with a better treatment outcome.展开更多

METHODS: Plasma acute phase proteins (APP),jejunal APP mRNA levels,liver and jejunal glutathione concentrations were measured before and one,three and seven days after turpentine injection in 4 groups of control,protein-restricted,protein-restricted rats supplemented with glutamine or protein powder. Bacterial translocation in mesenteric lymph nodes and intestinal morphology were also assessed. RESULTS: Protein deprivation and turpentine injection significantly reduced jejunal villus height,and crypt depths. Mucosal glutathione concentration significantly decreased in protein-restricted rats. Before turpentine oil,glutamine supplementation restored villus heights and glutathione concentration (3.24 ± 1.05 vs 1.72 ± 0.46 μmol/g tissue,P < 0.05) in the jejunum,whereas in the liver glutathione remained low. Glutamine markedly increased jejunal α1-acid glycoprotein mRNA level after turpentine oil but did not affect its plasma concentration. Bacterial translocation in protein-restricted rats was not prevented by glutamine or protein powder supplementation. CONCLUSION: Glutamine restored gut glutathione stores and villus heights in malnourished rats but had no preventive effect on bacterial translocation in our model.展开更多

METHODS:Expression of CCN2/CTGF,p-STAT3,p-Smad 3/1 and p-Smad2 was examined in primary freshly isolated rat or cryo-preserved human PC exposed to various stimuli by Western blotting,electrophoretic mobility shift assay(EMSA) ,reporter-gene-assays and reversetranscriptase polymerase chain reaction. RESULTS:IL-6 strongly down-regulated CCN2/CTGF protein and mRNA expression in PC,enhanceable by extracellular presence of the soluble IL-6 receptor gp80,and supported by an inverse relation between IL-6 and CCN2/CTGF concentrations in patients'sera.The inhi-bition of TGFβ1 driven CCN2/CTGF expression by IL-6 did not involve a modulation of Smad2(and Smad1/3) signalling.However,the STAT3 SH2 domain binding peptide,a selective inhibitor of STAT3 DNA binding activity,counteracted the inhibitory effect of IL-6 on CCN2/CTGF expression much more pronounced than pyrrolidine-dithiocarbamate,an inhibitor primarily of STAT3 phosphorylation.An EMSA confirmed STAT3 binding to the proposed proximal STAT binding site in the CCN2/CTGF promoter. CONCLUSION:CCN2/CTGF is identified as a hepatocellular negative acute phase protein which is downregulated by IL-6 via the STAT3 pathway through interaction on the DNA binding level.展开更多

METHODS： Twenty-seven patients with ulcerative colitis （UC） and 17 healthy control subjects were studied. The patients were categorised as severe （n = 9）, moderate （n = 10） and mild groups （n = 8） using Truelove and Witts＇ classification of ulcerative colitis. Microheterogeneity of ACT, AGP and Tf was analysed by crossed immunoaffinity electrophoresis （CIAE） with concanavalin A. In all serum samples standard electrophoresis of serum proteins was performed, iron （Fe） concentration, total iron binding capacity （TIBC） and C-reactive protein （CRP） were also measured. RESULTS： Our patients suffering from ulcerative colitis had significantly higher serum ACT and AGP concentrations and lower serum transferrin concentration in comparison to healthy subjects. Changes in concentrations of acute phase proteins were dependent on the activity of the inflammatory process. The glycosylation patterns of transferrin were related to the inflammation status. We also observed the correlation between ACT and AGP concentrations, patterns of transferrin glycosylation and changes in standard protein electrophoresis or blood cell count. CONCLUSION： The glycosylation patterns of transferrin obtained from patients suffering from ulcerative colitis are highly branched and sialylated compared with those obtained from healthy subjects. In contrast, the glycosylation patterns of transferrin do not differ according to the activity index of ulcerative colitis. The microheterogeneity patterns of AGP and ACT are similar in ulcerative colitis patients and healthy subjects.展开更多

METHODS: Wistar rats were injected intravenous with either the CD163 targeted dexamethasone-conjugate(0.02 mg/kg) or free dexamethasone(0.02 or 1 mg/kg) 24 h prior to lipopolysaccharide(LPS)(2.5 mg/kg intraperitoneal). We measured plasma concentrations of tumour necrosis factor-a(TNF-a) and interleukin 6(IL-6) 2 h post-LPS and liver m RNAs and serum concentrations of the rat acute phase protein a-2-macroglobulin(a-2-M) 24 h after LPS. Also, plasma concentrations of alanine aminotransferase and bilirubin were measured at termination of the study. Spleen weight served as an indicator of systemic steroid effects.RESULTS: The conjugate halved the a-2-M liver m RNA(3.3 ± 0.6 vs 6.8 ± 1.1, P < 0.01) and serum protein(201 ± 48 μg/mL vs 389 ± 67 μg/mL, P = 0.04) after LPS compared to low dose dexamethasone treated animals, while none of the free dexamethasone doses had an effect on liver m RNA or serum levels of a-2-M. Also, the conjugate reduced TNF-a(7208 ± 1977 pg/mL vs 21583 ± 7117 pg/mL, P = 0.03) and IL-6(15685 ± 3779 pg/mL vs 25715 ± 4036 pg/mL, P = 0.03) compared to the low dose dexamethasone. The high dose dexamethasone dose decreased the spleen weight(421 ± 11 mg vs 465 ± 12 mg, P < 0.05) compared to controls, an effect not seen in any other group.CONCLUSION: Low-dose anti-CD163-dexamethasone conjugate effectively decreased the hepatic acute phase response to LPS. This indicates an anti-inflammatory potential of the conjugate in vivo.展开更多

Occlusion with coils is the first line treatment for ruptured aneurysms and also should be used to prevent re-rupture, potentially causing severe brain damage. Most aneurysms are subject to this type of treatment. The risk of intraoperative thromboembolic and haemorrhagic complications during treatment with coils is very low. Endovascular treatment with coils is therefore a safe and effective method that can prevent short and long-term haemorrhage. Short and long-term haemorrhage is achieved by early recanalization of cases with neuro-visualisation. Methods: In this article we present a retrospective analysis of the results of endovascular embolization of 137 patients, from 2017 to the present time, in three hospitals of Georgia country (Evex hospitals, New hospitals, New-vision University Hospital) with a diagnosis of acute subarachnoid haemorrhage. Results: In our study, overall postoperative mortality was reported to be 29.9% (41/137 patients). In 45 patients presenting with Hunt-Hess IV-V, the mortality rate was 51.1% (23/45). According to Raymond-Roy Scale, complete occlusion of aneurysm occurs in 66% of cases, residual occlusion of neck in 26%, and partial occlusion in 6%. Conclusion: Aneurysm rupture is an urgent clinical condition requiring rapid diagnosis and treatment. To prevent aneurysm re-rupture, operative intervention should be performed quickly. The recommended time interval is within 72 hours, and, if possible, within 24 hours after aneurysm rupture. Given the spasms typical of subarachnoid haemorraghe endovascular coiling of ruptured aneurysms is a first-line treatment that depends on the angioarchitecture and localization of the aneurysm. The main technique of endovascular treatment is occlusion by coils with or without remodeling balloon assistance. Generally, in acute periods, only aneurysms with coils are associated with relatively high rates of recanalization, so further observation and possible surgical treatment are recommended.展开更多

Methods: One Iranian sheep naturally infected with A. ovis(parasitemia 0.02%) but with no other blood parasites based on blood smear and polymerase chain reaction methods was selected as donor, and it was splenectomized to induce high level of parasitemia. Then, three weeks after splenectomy when parasitemia was 6%, donor's blood was intravenously administered to each recipient animal. Five 5-6 months old Iranian male sheep without any blood parasites were selected as recipient animals. The percent of parasites, packed cell volume, serum biochemical parameters(urea, creatinine, bilirubin, aspartate aminotransferase activity, cholesterol, total protein, albumin, globulin, Fe), acute phase proteins(haptoglobin, total iron binding capacity, fibrinogen), were evaluated in sheep before and after being experimentally infected with A. ovis(until day 38). In addition, body weights of sheep were measured on days 0, 20 and 38. Results: In recipient sheep, microscopic examination of erythrocytes revealed a significant rise of parasitemia on days 12 and 15. The lowest level of packed cell volume in sheep was seen on day 15 post infection. A significant rise existed in mean urea and bilirubin(total, direct and indirect) on days 15 and 20. The increase of indirect bilirubin level was higher than direct bilirubin. Furthermore, serum Fe significantly increased on days 20 and 23. The mean total protein concentration significantly increased on day 38. A significant increase was found in the serum globulin concentration from days 20 and 27 to 38. Maximum values of haptoglobin were observed on days 27 and 30. Moreover, aspartate aminotransferase activity(from days 20-30) and cholesterol concentration(on day 20) significantly decreased. However, no significant changes were found in other parameters. Conclusions: Experimental ovine anaplasmosis caused by A. ovis could be associated with some changes in measured parameters, which presumably could be helpful for evaluation on staging of disease.展开更多

Methods and Results: The study is about 2 series, series A between 1993 and 1997, and series B between 1998 and 2012, respectively 13 and 51 patients. The two periods were similar concerning the number of patients per year, which was 3.12 cases/year for series A and 3.64 cases/year for series B. The authors noted a change in epidemiological profile, with an increase of median age (31 y.o for series A and 37 y.o for series B), and the emergency of endocarditis on prosthetic valve (none on series A and 8 cases for series B). Surgical indications and results didn’t change too much, hospital mortality rate was 15.3% for series A and 17.6% for series B. Conclusion: Infectious endocarditis is still a major public healthcare problem in developing countries, despite the development of diagnostic tools and patient care. Prevention is still the major asset in the treatment of this disease.展开更多

Methods： 60 clinically collected cases were chosen in the study and randomly divided into control group and treatment group. In control group, dexamethasone, vitamin B, vitamin B 12, and mecobalamine were applied in acute phase, and then acupuncture therapy was combined in remission. In treatment group, western medicine combining with acupuncture therapy was used in acute phase, and three courses of treatment were totally applied. Results： The final conditions of two groups were good, and the grouping was balanced, so the comparability between them was good （P〉0.05）; the curative effects of two groups were significantly different： the effect of treatment group was better than that of control group （P〈0.01）. Conclusion： The acute phase was necessarily grasped to apply acupuncture therapy to the treatment of peripheral facial neuritis, and the curative effect would be more significant if acupuncture therapy was more early used.展开更多

The impact of this clinical deterioration on long-term outcomes is unknown. We characterized the clinical features of neurological deterioration （ND） in the acute phase of minor ischemic stroke （MIS） and investigated its impact on mid- and long-term outcomes. Methods This was a multi-centered, prospective clinical study involving patients with MIS （the National Institutes of Health Stroke Scale, NIHSS ~3） recruited from the China National Stroke Registry. Patients were included who had been hospitalized within 24 hours of stroke onset. Baseline characteristics, complication rates during hospitalization, etiology of stroke, as well as 3-, 6-, and 12-month post-stroke outcomes were compared between patients with and without ND during the acute phase. Results A number of 368 （15.2%） out of 2424 patients included in the study exhibited ND in the acute phase. Compared to patients without ND, patients with ND had longer hospital stay, increased rate of baseline diabetes, and multiple complications. Multivariate Logistic regression indicated that ND in acute phase was an independent factor predictive of increased dependence （adjusted odds ratio = 5.20, 95% CI, 3.51-7.70, P 〈0.001） at 12-month post-stroke. Conclusions The risk of ND in the acute phase is high in patients with MIS. ND in the acute phase is an independent predictor for poor outcomes at 12 months post-stroke onset.展开更多

Methods: The levels of C-reactive protein (CRP),α1-acid glycoprotein (AAG), α1-antitrypsin total (α1AT), α2-macroglobulin (α2-MG), ceruloplasmine (CP), hepatoglobin (HP) and transferrin (TF) synthesis were determined in 32 cases of MODS patients and rat models of MODS induced by acute infective peritonitis and mesenterial artery ischemia-reperfusion.Results: The serum APP level in MODS patients was increased and higher than that in the control group (P < 0. 01 ). After 3 days of DCQD treatment it reduced significantly (P <0. 05). Serum APP level in MODS model was also increased significantly, and after 3 days of DCQD treatment, it reduced significantly (P < 0. 05). The APP secreting level of rat hepatocytes cultured in vitro raised after stimulated and activated by lipopolysacchride, which was reduced after cultured with rabbits serum containing different concentration of effective ingredients of DCQD. The APP inhibiting effect of DCQD was dose dependent. Conclusion: Purgation therapy with DCQD could reduce the stimulation of pathogenic factors on hepatocytes, protect tissues and organs from damage caused by excessive inflammatory reaction.Original article on CJIM(Chin) 1998; 18(8): 453展开更多

文摘BACKGROUND Fibro-adipogenic progenitors(FAPs)are a group of mesenchymal stem cells that cause fibro-fatty degeneration in skeletal muscle in various chronic disease mode-ls.FAPs also play a role in preventing muscle degeneration at acute stages during disease progression.However,few studies have reported the changes in and function of FAPs in the acute phase after tendon rupture.AIM To clarify the changes in the number of FAPs and their impact on skeletal muscle soon after tendon rupture to facilitate future studies targeting FAPs to treat muscle degeneration.METHODS We utilized Pdgfra-H2B::eGFP mice to trace and quantify FAPs in a tibialis anterior tenotomy(TAT)model at 0 and 3 days,1 week,2 weeks,3 weeks,4 weeks,5 weeks,and 6 weeks post-injury,and the results were further validated using fluorescence-activated cell sorting analysis with C57BL/6 mice at the same post-injury timepoints.We subsequently used PdgfraCreERT::RosaDTA mice,and evaluated the severity of post-TAT skeletal muscle degeneration with or without FAP-depletion.RESULTS The number of FAPs peaked at 1 week post-TAT before gradually declining to a level comparable to that pre-TAT.The change in the number of FAPs was potentially temporally correlated with the progression of skeletal muscle degeneration after TAT.FAP-depletion led to more severe degeneration early after TAT,indicating that FAPs potentially alleviate muscle degeneration after tendon rupture in the early post-injury phase.CONCLUSION FAPs potentially alleviate the degeneration of skeletal muscle in the acute stage after tendon rupture.

文摘A review of the systemic acute phase reaction with major cytokines involved, and the hepatic metabolic changes, negative and positive acute phase proteins (APPs) with function and associated pathology is given. It appears that APPs represent appropriate analytes for assessment of animal health. Whereas they represent non-specific markers as biological effect reactants, they can be used for assessing nutritional deficits and reactive processes, especially when positive and negative acute phase variables are combined in an index. When such acute phase index is applied to separate healthy animals from animals with some disease, much better results are obtained than with single analytes and statistically acceptable results for culling individual animals may be reached. Unfortunately at present no cheap, comprehensive and easy to use system is available for assessing various acute phase proteins in serum or blood samples at the same time. Protein microarray or fluid phase microchip technology may satisfy this need; and permit simultaneous analysis of numerous analytes in the same small volume sample and enable integration of information derived from systemic reactivity and nutrition with disease specific variables. Applying such technology may help to solve health problems in various countries not only in animal husbandry but also in human populations.
文摘BACKGROUND Uncontrolled growth and loss of control over basic metabolic functions,leading to invasive proliferation and metastases,are the salient traits of malignant tumors in general and colorectal cancer in particular.Invasion and metastases hinder effective tumor treatment.While surgical techniques and radiotherapy can be used to remove tumor focus,only chemotherapy can eliminate dispersed neoplastic cells.However,the efficacy of the latter method is limited in the advanced stages of the disease.Therefore,recognition of the mechanisms involved in neoplastic cell spreading is indispensable for developing effective therapies.AIM To use a number of biomarkers involved in cancer progression and identify a panel that could be used for effective early diagnosis.METHODS We recruited 185 patients with colorectal adenocarcinoma(98 men,87 women with median age 63).Thirty-five healthy controls were sex and age-matched.Dukes’staging was as follows:A=22,B=52,C=72,D=39.We analyzed patients'blood serum before surgery.We determined:(1)Cathepsin B(CB)with Barrett's method(fluorogenic substrate);(2)Leukocytic elastase(LE)in a complex with alpha 1 trypsin inhibitor(AAT)using the immunoenzymatic MERCK test;(3)Total sialic acid(TSA)with the colorimetric periodate-resorcinol method;(4)Lipid-bound sialic acid(LASA)with the colorimetric Taut's method;and(5)The antitrypsin activity(ATA)employing the colorimetric test.RESULTS In patients,the values of the five biochemical parameters were as follows:CB=16.1±8.8 mU/L,LE=875±598μg/L,TSA=99±31 mg%,LASA=0.68±0.33 mg%,and ATA=3211±1504 U/mL.Except for LASA,they were significantly greater than those of controls:CB=11.4±6.5 mU/L,LE=379±187μg/L,TSA=71.4±15.1 mg%,LASA=0.69±0.28 mg%,and ATA=2016±690 U/mL.For CB and LASA,the differences between the four Dukes’stages and controls were not statistically significant.The inter-stage differences for CB and LASA were also absent.The receiver operating characteristic(ROC)analysis revealed the potential diagnostic value of CB,TSA,and ATA.The area under ROC,sensitivity,and specificity for these three parameters were:0.85,72%,90%;0.75,66%,77%;and 0.77,63%,84%,respectively.The sensitivity and specificity for the threeparameter panel CB-TSA-ATA were equal to 88.2%and 100%,respectively.CONCLUSION The increased value of CB,TSA,and ATA parameters are associated with tumor biology,invasion,and metastasis of colorectal cancer.The presented evidence suggests the potential value of the CB-TSA-ATA biochemical marker panel in early diagnostics.

文摘Many clinical studies have addressed the treatment of acute cerebral hemorrhage using acupuncture. However, few studies have examined the relationship between time of acupuncture and curative effect on cerebral hemorrhage. By observing the effect of acupuncture on changes in histopathology, ultrastructure, and neuroethology in a cerebral hemorrhage model of rats, we have directly examined the time-effect relationship of acupuncture. The rat model of cerebral hemorrhage was produced by slowly injecting autologous blood to the right caudate nucleus. The experimental groups were: 3-, 9-, 24-, and 48-hour model groups; and 3-, 9-, 24-, and 48-hour acupuncture groups. The sham-operation group was used for comparison. Acupuncture was performed at the Neiguan(PC6) and Renzhong(DU26) acupoints, twice a day, 6 hours apart, for 5 consecutive days. Brain tissue changes were observed by light microscopy and transmission electron microscopy. Neuroethology was assessed using Bederson and Longa scores. Our results show that compared with the sham-operation and model groups, Bederson and Longa scores were lower in each acupuncture group, with visibly improved histopathology and brain tissue ultrastructure. Further, the results were better in the 3-and 9-hour acupuncture groups than the 24-and 48-hour acupuncture groups. Our findings show that acupuncture treatment can relieve pathological and ultrastructural deterioration and neurological impairment caused by the acute phase of cerebral hemorrhage, and may protect brain tissue during this period. In addition, earlier acupuncture intervention following cerebral hemorrhage(by 3 or 9 hours) is associated with a better treatment outcome.
文摘Ischemic stroke occurs under a variety of clinical conditions and has different pathogeneses,resulting in necrosis of brain parenchyma.Stroke pathogenesis is characterized by neuroinflammation and endothelial dysfunction.Some of the main processes triggered in the early stages of ischemic damage are the rapid activation of resident inflammatory cells(microglia,astrocytes and endothelial cells),inflammatory cytokines,and translocation of intercellular nuclear factors.Inflammation in stroke includes all the processes mentioned above,and it consists of either protective or detrimental effects concerning the“polarization”of these processes.This polarization comes out from the interaction of all the molecular pathways that regulate genome expression:the epigenetic factors.In recent years,new regulation mechanisms have been cleared,and these include non-coding RNAs,adenosine receptors,and the activity of mesenchymal stem/stromal cells and microglia.We reviewed how long non-coding RNA and microRNA have emerged as an essential mediator of some neurological diseases.We also clarified that their roles in cerebral ischemic injury may provide novel targets for the treatment of ischemic stroke.To date,we do not have adequate tools to control pathophysiological processes associated with stroke.Our goal is to review the role of non-coding RNAs and innate immune cells(such as microglia and mesenchymal stem/stromal cells)and the possible therapeutic effects of their modulation in patients with acute ischemic stroke.A better understanding of the mechanisms that influence the“polarization”of the inflammatory response after the acute event seems to be the way to change the natural history of the disease.
文摘AIM: To evaluate the effect of glutamine on intestinal mucosa integrity,glutathione stores and acute phase response in protein-depleted rats during an inflammatory shock. METHODS: Plasma acute phase proteins (APP),jejunal APP mRNA levels,liver and jejunal glutathione concentrations were measured before and one,three and seven days after turpentine injection in 4 groups of control,protein-restricted,protein-restricted rats supplemented with glutamine or protein powder. Bacterial translocation in mesenteric lymph nodes and intestinal morphology were also assessed. RESULTS: Protein deprivation and turpentine injection significantly reduced jejunal villus height,and crypt depths. Mucosal glutathione concentration significantly decreased in protein-restricted rats. Before turpentine oil,glutamine supplementation restored villus heights and glutathione concentration (3.24 ± 1.05 vs 1.72 ± 0.46 μmol/g tissue,P < 0.05) in the jejunum,whereas in the liver glutathione remained low. Glutamine markedly increased jejunal α1-acid glycoprotein mRNA level after turpentine oil but did not affect its plasma concentration. Bacterial translocation in protein-restricted rats was not prevented by glutamine or protein powder supplementation. CONCLUSION: Glutamine restored gut glutathione stores and villus heights in malnourished rats but had no preventive effect on bacterial translocation in our model.
文摘AIM:To investigate the mechanisms involved in a possible modulator role of interleukin(IL) -6 signalling on CYR61-CTGF-NOV(CCN) 2/connective tissue growth factor(CTGF) expression in hepatocytes(PC) and to look for a relation between serum concentrations of these two parameters in patients with acute inflammation. METHODS:Expression of CCN2/CTGF,p-STAT3,p-Smad 3/1 and p-Smad2 was examined in primary freshly isolated rat or cryo-preserved human PC exposed to various stimuli by Western blotting,electrophoretic mobility shift assay(EMSA) ,reporter-gene-assays and reversetranscriptase polymerase chain reaction. RESULTS:IL-6 strongly down-regulated CCN2/CTGF protein and mRNA expression in PC,enhanceable by extracellular presence of the soluble IL-6 receptor gp80,and supported by an inverse relation between IL-6 and CCN2/CTGF concentrations in patients'sera.The inhi-bition of TGFβ1 driven CCN2/CTGF expression by IL-6 did not involve a modulation of Smad2(and Smad1/3) signalling.However,the STAT3 SH2 domain binding peptide,a selective inhibitor of STAT3 DNA binding activity,counteracted the inhibitory effect of IL-6 on CCN2/CTGF expression much more pronounced than pyrrolidine-dithiocarbamate,an inhibitor primarily of STAT3 phosphorylation.An EMSA confirmed STAT3 binding to the proposed proximal STAT binding site in the CCN2/CTGF promoter. CONCLUSION:CCN2/CTGF is identified as a hepatocellular negative acute phase protein which is downregulated by IL-6 via the STAT3 pathway through interaction on the DNA binding level.
文摘AIM： TO estimate the serum α1-antichymotrypsin （ACT）, α1-acid glycoprotein （AGP） and transferrin （Tf） concentrations and to evaluate the microheterogeneity of these acute phase proteins in patients with ulcerative colitis. METHODS： Twenty-seven patients with ulcerative colitis （UC） and 17 healthy control subjects were studied. The patients were categorised as severe （n = 9）, moderate （n = 10） and mild groups （n = 8） using Truelove and Witts＇ classification of ulcerative colitis. Microheterogeneity of ACT, AGP and Tf was analysed by crossed immunoaffinity electrophoresis （CIAE） with concanavalin A. In all serum samples standard electrophoresis of serum proteins was performed, iron （Fe） concentration, total iron binding capacity （TIBC） and C-reactive protein （CRP） were also measured. RESULTS： Our patients suffering from ulcerative colitis had significantly higher serum ACT and AGP concentrations and lower serum transferrin concentration in comparison to healthy subjects. Changes in concentrations of acute phase proteins were dependent on the activity of the inflammatory process. The glycosylation patterns of transferrin were related to the inflammation status. We also observed the correlation between ACT and AGP concentrations, patterns of transferrin glycosylation and changes in standard protein electrophoresis or blood cell count. CONCLUSION： The glycosylation patterns of transferrin obtained from patients suffering from ulcerative colitis are highly branched and sialylated compared with those obtained from healthy subjects. In contrast, the glycosylation patterns of transferrin do not differ according to the activity index of ulcerative colitis. The microheterogeneity patterns of AGP and ACT are similar in ulcerative colitis patients and healthy subjects.

文摘AIM: To study the effect of a new anti-CD163-dexamethasone conjugate targeting activated macrophages on the hepatic acute phase response in rats. METHODS: Wistar rats were injected intravenous with either the CD163 targeted dexamethasone-conjugate(0.02 mg/kg) or free dexamethasone(0.02 or 1 mg/kg) 24 h prior to lipopolysaccharide(LPS)(2.5 mg/kg intraperitoneal). We measured plasma concentrations of tumour necrosis factor-a(TNF-a) and interleukin 6(IL-6) 2 h post-LPS and liver m RNAs and serum concentrations of the rat acute phase protein a-2-macroglobulin(a-2-M) 24 h after LPS. Also, plasma concentrations of alanine aminotransferase and bilirubin were measured at termination of the study. Spleen weight served as an indicator of systemic steroid effects.RESULTS: The conjugate halved the a-2-M liver m RNA(3.3 ± 0.6 vs 6.8 ± 1.1, P < 0.01) and serum protein(201 ± 48 μg/mL vs 389 ± 67 μg/mL, P = 0.04) after LPS compared to low dose dexamethasone treated animals, while none of the free dexamethasone doses had an effect on liver m RNA or serum levels of a-2-M. Also, the conjugate reduced TNF-a(7208 ± 1977 pg/mL vs 21583 ± 7117 pg/mL, P = 0.03) and IL-6(15685 ± 3779 pg/mL vs 25715 ± 4036 pg/mL, P = 0.03) compared to the low dose dexamethasone. The high dose dexamethasone dose decreased the spleen weight(421 ± 11 mg vs 465 ± 12 mg, P < 0.05) compared to controls, an effect not seen in any other group.CONCLUSION: Low-dose anti-CD163-dexamethasone conjugate effectively decreased the hepatic acute phase response to LPS. This indicates an anti-inflammatory potential of the conjugate in vivo.
文摘Introduction: Ruptured intracranial aneurysm is an urgent diagnostic and therapeutic condition. Occlusion with coils is the first line treatment for ruptured aneurysms and also should be used to prevent re-rupture, potentially causing severe brain damage. Most aneurysms are subject to this type of treatment. The risk of intraoperative thromboembolic and haemorrhagic complications during treatment with coils is very low. Endovascular treatment with coils is therefore a safe and effective method that can prevent short and long-term haemorrhage. Short and long-term haemorrhage is achieved by early recanalization of cases with neuro-visualisation. Methods: In this article we present a retrospective analysis of the results of endovascular embolization of 137 patients, from 2017 to the present time, in three hospitals of Georgia country (Evex hospitals, New hospitals, New-vision University Hospital) with a diagnosis of acute subarachnoid haemorrhage. Results: In our study, overall postoperative mortality was reported to be 29.9% (41/137 patients). In 45 patients presenting with Hunt-Hess IV-V, the mortality rate was 51.1% (23/45). According to Raymond-Roy Scale, complete occlusion of aneurysm occurs in 66% of cases, residual occlusion of neck in 26%, and partial occlusion in 6%. Conclusion: Aneurysm rupture is an urgent clinical condition requiring rapid diagnosis and treatment. To prevent aneurysm re-rupture, operative intervention should be performed quickly. The recommended time interval is within 72 hours, and, if possible, within 24 hours after aneurysm rupture. Given the spasms typical of subarachnoid haemorraghe endovascular coiling of ruptured aneurysms is a first-line treatment that depends on the angioarchitecture and localization of the aneurysm. The main technique of endovascular treatment is occlusion by coils with or without remodeling balloon assistance. Generally, in acute periods, only aneurysms with coils are associated with relatively high rates of recanalization, so further observation and possible surgical treatment are recommended.

文摘Objective: To determine the biochemical and acute phase proteins changes in sheep experimentally infected with Anaplasma ovis(A. ovis). Methods: One Iranian sheep naturally infected with A. ovis(parasitemia 0.02%) but with no other blood parasites based on blood smear and polymerase chain reaction methods was selected as donor, and it was splenectomized to induce high level of parasitemia. Then, three weeks after splenectomy when parasitemia was 6%, donor's blood was intravenously administered to each recipient animal. Five 5-6 months old Iranian male sheep without any blood parasites were selected as recipient animals. The percent of parasites, packed cell volume, serum biochemical parameters(urea, creatinine, bilirubin, aspartate aminotransferase activity, cholesterol, total protein, albumin, globulin, Fe), acute phase proteins(haptoglobin, total iron binding capacity, fibrinogen), were evaluated in sheep before and after being experimentally infected with A. ovis(until day 38). In addition, body weights of sheep were measured on days 0, 20 and 38. Results: In recipient sheep, microscopic examination of erythrocytes revealed a significant rise of parasitemia on days 12 and 15. The lowest level of packed cell volume in sheep was seen on day 15 post infection. A significant rise existed in mean urea and bilirubin(total, direct and indirect) on days 15 and 20. The increase of indirect bilirubin level was higher than direct bilirubin. Furthermore, serum Fe significantly increased on days 20 and 23. The mean total protein concentration significantly increased on day 38. A significant increase was found in the serum globulin concentration from days 20 and 27 to 38. Maximum values of haptoglobin were observed on days 27 and 30. Moreover, aspartate aminotransferase activity(from days 20-30) and cholesterol concentration(on day 20) significantly decreased. However, no significant changes were found in other parameters. Conclusions: Experimental ovine anaplasmosis caused by A. ovis could be associated with some changes in measured parameters, which presumably could be helpful for evaluation on staging of disease.
文摘The feasibility of a commercially available assay for C-reactive protein(CRP,CRP for humans:hCRP,and CRP for dogs:vCRP)and a trial reagent of serum amyloid A(SAA,vSAA for animals)were applied to the measurement of acute phase proteins in zoo animals,particularly in nonhuman primates and feline carnivores was evaluate.Results showed that hCRP and vSAA methods were applicable to measure CRP and SAA in Haplorhini.There was a highly signifcant correlation between both parameters with remarkably high correlation coefcient.A higher proportion of Bonnet macaques in Haplorhini,and the linear regression with good correlation between hCRP and vSAA levels were observed.Reference values in healthy Bonnet macaques were hCRP(46.86±30.97 nmol/L)and vSAA(9.06±1.95μg/mL).Although Ring-tailed lemur,which belonging to Strepsirrhini,showed low vSAA concentrations(reference values:1.08±0.47μg/mL),vSAA in patients was apparently elevated.The vCRP and vSAA methods were applicable to measurements of CRP and SAA in feline carnivores for highly signifcant correlation between both parameters.Theses two methods were also been deteded in lions,tigers and cheetahs.vSAA assays can be applied to measure SAA levels in other carnivores and herbivores.In conclusion,vSAA systems have potential utility as diagnostic tools for health screening and prediction in zoo animals.
文摘A variety of changes occur in the rabbit under metal stress which include the appearance of the acute phase protein, C-reactive protein in the serum and significant reduction in the serum litres of albumin and acetylcholinesterase. The phospholipid profile is positively correlated with the higher degree of tissue necrosis encountered in mercury treated rabbit. Cadmium and mercury treatments evoke a similar response pattern in rabbit differing only in the degree of change.
文摘Aim: Comparing the results of acute phase infectious endocarditis surgery between two periods. Methods and Results: The study is about 2 series, series A between 1993 and 1997, and series B between 1998 and 2012, respectively 13 and 51 patients. The two periods were similar concerning the number of patients per year, which was 3.12 cases/year for series A and 3.64 cases/year for series B. The authors noted a change in epidemiological profile, with an increase of median age (31 y.o for series A and 37 y.o for series B), and the emergency of endocarditis on prosthetic valve (none on series A and 8 cases for series B). Surgical indications and results didn’t change too much, hospital mortality rate was 15.3% for series A and 17.6% for series B. Conclusion: Infectious endocarditis is still a major public healthcare problem in developing countries, despite the development of diagnostic tools and patient care. Prevention is still the major asset in the treatment of this disease.
文摘Objective： This study aimed to prove acupuncture therapy exerted an obvious clinical efficacy in the treatment of peripheral facial neuritis in acute phase. Methods： 60 clinically collected cases were chosen in the study and randomly divided into control group and treatment group. In control group, dexamethasone, vitamin B, vitamin B 12, and mecobalamine were applied in acute phase, and then acupuncture therapy was combined in remission. In treatment group, western medicine combining with acupuncture therapy was used in acute phase, and three courses of treatment were totally applied. Results： The final conditions of two groups were good, and the grouping was balanced, so the comparability between them was good （P〉0.05）; the curative effects of two groups were significantly different： the effect of treatment group was better than that of control group （P〈0.01）. Conclusion： The acute phase was necessarily grasped to apply acupuncture therapy to the treatment of peripheral facial neuritis, and the curative effect would be more significant if acupuncture therapy was more early used.
文摘Objective:To explore the clinical efficacy and safety of Naomaili granules in the treatment of acute ischemic stroke.Methods:Eighty-eight patients were randomly divided into a treatment group and a control group,with 44 patients in each group.The control group received conventional Western medicine treatment,while the treatment group was additionally administered Naomaili granules at 10g per time,3 times per day,for 20 days.Neurological function(NIHSS),activities of daily living(BI),inflammatory factors(hs-CRP,IL-6)levels,and adverse reactions were observed before and after treatment.Results:After 20 days of treatment,the NIHSS score of the treatment group decreased from(9.20±2.10)to(5.12±1.30),the BI index increased from(52.30±8.50)to(78.60±9.20),and hs-CRP and IL-6 decreased to(3.12±1.10)mg/L and(18.20±4.20)pg/mL,respectively,all significantly better than the control group(P<0.01).The incidence of adverse reactions in the treatment group was 4.55%,lower than the 15.91%in the control group(P<0.05).Conclusion:Naomaili granules can improve neurological function and living ability,reduce inflammatory response,and have good safety in patients with acute ischemic stroke.

文摘Background The risk of clinical deterioration still exists in the acute phase despite the fact that patients with minor stroke may display less severe symptoms. The impact of this clinical deterioration on long-term outcomes is unknown. We characterized the clinical features of neurological deterioration （ND） in the acute phase of minor ischemic stroke （MIS） and investigated its impact on mid- and long-term outcomes. Methods This was a multi-centered, prospective clinical study involving patients with MIS （the National Institutes of Health Stroke Scale, NIHSS ~3） recruited from the China National Stroke Registry. Patients were included who had been hospitalized within 24 hours of stroke onset. Baseline characteristics, complication rates during hospitalization, etiology of stroke, as well as 3-, 6-, and 12-month post-stroke outcomes were compared between patients with and without ND during the acute phase. Results A number of 368 （15.2%） out of 2424 patients included in the study exhibited ND in the acute phase. Compared to patients without ND, patients with ND had longer hospital stay, increased rate of baseline diabetes, and multiple complications. Multivariate Logistic regression indicated that ND in acute phase was an independent factor predictive of increased dependence （adjusted odds ratio = 5.20, 95% CI, 3.51-7.70, P 〈0.001） at 12-month post-stroke. Conclusions The risk of ND in the acute phase is high in patients with MIS. ND in the acute phase is an independent predictor for poor outcomes at 12 months post-stroke onset.
文摘Objective: To investigate the level of acute phase proteins (APP)-synthesized in hepatocytes in pathogenic process of multiple organ dysfunction syndrome (MODS) and the effect of Dachengqi Decoction (DCQD) on it. Methods: The levels of C-reactive protein (CRP),α1-acid glycoprotein (AAG), α1-antitrypsin total (α1AT), α2-macroglobulin (α2-MG), ceruloplasmine (CP), hepatoglobin (HP) and transferrin (TF) synthesis were determined in 32 cases of MODS patients and rat models of MODS induced by acute infective peritonitis and mesenterial artery ischemia-reperfusion.Results: The serum APP level in MODS patients was increased and higher than that in the control group (P < 0. 01 ). After 3 days of DCQD treatment it reduced significantly (P <0. 05). Serum APP level in MODS model was also increased significantly, and after 3 days of DCQD treatment, it reduced significantly (P < 0. 05). The APP secreting level of rat hepatocytes cultured in vitro raised after stimulated and activated by lipopolysacchride, which was reduced after cultured with rabbits serum containing different concentration of effective ingredients of DCQD. The APP inhibiting effect of DCQD was dose dependent. Conclusion: Purgation therapy with DCQD could reduce the stimulation of pathogenic factors on hepatocytes, protect tissues and organs from damage caused by excessive inflammatory reaction.Original article on CJIM(Chin) 1998; 18(8): 453
文摘BACKGROUND Familial Mediterranean fever(FMF)is an autosomal recessive autoinflammatory disorder marked by recurrent episodes of fever and serositis.Resistin,a proinflammatory cytokine,may play a role in FMF pathogenesis by promoting the release of interleukin-1beta,tumour necrosis factor alpha,and interleukin-6.AIM To evaluate serum resistin levels in children with FMF during acute attacks and remission,and to assess its potential as a biomarker for disease activity and progression.METHODS A case-control study was conducted involving 40 pediatric patients with FMF and 40 age-and sex-matched healthy controls.Serum resistin and inflammatory markers—including total leukocyte count(TLC),erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),serum amyloid A(SAA),and fibrinogen—were measured using enzyme-linked immunosorbent assay and standard assays.RESULTS No significant differences were found in age or sex between FMF patients and controls.Among FMF patients,fever was the most prevalent symptom(95%),followed by abdominal pain(75%).The most frequently detected genetic mutation was M694I,followed by M694V,E148Q,M680I,and V726A.Compound heterozygous mutations,including M694I/V726A and M694I/M694V,were equally represented.During acute attacks,FMF patients exhibited significantly elevated levels of TLC,ESR,CRP,SAA,and fibrinogen compared to attack-free periods and controls.Serum resistin levels were markedly higher during acute attacks and showed a strong positive correlation with other acute inflammatory markers.Receiver operating characteristic curve analysis demonstrated high sensitivity and specificity of resistin as a potential biomarker for FMF.CONCLUSION Resistin is significantly elevated in children with FMF during acute episodes and correlates with established inflammatory markers.These findings support its potential role as a non-invasive biomarker for disease activity and severity in pediatric FMF.
