Methods: Sixty patients diagnosed with anemia (disease group) from June 2021 to June 2024 were selected. Based on the type of disease, the group was subdivided into iron deficiency anemia (IDA) with 31 cases, hemolytic anemia (HA) with 11 cases, and aplastic anemia (AA) with 18 cases. Based on the severity of the disease, the group was divided into mild anemia (30 cases), moderate anemia (19 cases), and severe anemia (11 cases). Sixty healthy individuals (control group) were also included, and all underwent blood tests. Comparisons were made between the red blood cell (RBC) indicators of the disease group and the control group, the blood test indicators of different types of anemia, and the serum iron levels of varying severity of anemia. Results: Except for red cell distribution width (RDW), the RBC indicators in the disease group were lower than those in the control group (P < 0.05). Comparisons of RBC indicators among different types of anemia showed significant differences (P < 0.05). Serum iron levels varied significantly among different degrees of anemia severity (P < 0.05). Conclusion: Blood tests can detect anemia, distinguish types of anemia, and assess anemia severity, offering high diagnostic value.展开更多

However, the symptom of laying hens usually is not typical and hard to diagnosis. In the present study, it is studied that the influences of SE infection on layers＇ performance, egg quality and blood biochemical indicators. It will help us to improve the strategy to control SE infection in commercial layers. One hundred layers at 20 wk of age were divided into 2 groups, 60 hens for experiment and others for control. The experiment group was fed with the dosage of 108 CFU SE per hen. The specific PCR was used to detect the deposition of SE. On the 8 d after SE infection, 10 hens from the control group and 30 hens from the experimenta group were slaughtered to detect the SE colonization. The production performance, egg quality and blood biochemical indices were also analyzed. Results： The results showed that the colonization rate of SE was highest in caecum contents （55.17%） and lowest in vagina （17.24%）. For the eggs the detection rate of SE was highest on the eggshell （80.00%） and lowest in yolk （18.81%）. SE infection had no significant influence on production performance and egg qualities （P 〉 0.05）. The difference of laying rate between the experimental and control groups was less than 0.30%, and both were approximately equal to 82.00%. The blood analysis showed that the aspartic aminotransferase （AST） and alanine aminotransferase （ALT） of experimental group was significantly higher than those of control group （P 〈 0.05）. For experimental and control groups AST values were 236.22 U/I and 211.84 U/I respectively, and ALT values were 32.19 U/I and 24.55 U/I. All of coefficients were less than 20%. The colonization of SE in organs increases the enzyme activities of AST and ALT in blood. Conclusions： SE in feed could invade the oviduct and infect the forming eggs. It significantly increased the concentration of ALT and AST in blood. However,SE infection was hard to be observed from the appearances of layer and egg. It might be a dangerous risk to human health.展开更多

Methods: The study included 50 children diagnosed with Kawasaki disease as the study group, and 50 children with upper respiratory infections as the control group. Both groups underwent echocardiographic examinations to assess cardiac structure and function, while monitoring changes in blood-related inflammatory markers. The differences in echocardiographic and blood-related indicators before and after treatment between the two groups were compared. Results: Echocardiography effectively assessed the cardiac structure and function of children with Kawasaki disease. It was found that the ejection fraction (EF) in the treatment group significantly decreased from 69.94 ± 5.93% before treatment to 65.70 ± 5.56% after treatment (P = 0.0019), while the control group showed no significant change (from 70.94 ± 6.27% to 69.18 ± 6.14%, P = 0.2073). The aortic diameter (AO) in the treatment group increased from 12.85 ± 2.77 mm to 13.17 ± 2.41 mm (P = 0.0000), while in the control group it decreased from 18.58 ± 6.66 mm to 17.64 ± 6.83 mm (P = 0.0000), indicating potential vascular remodeling. In terms of blood indicators, the C-reactive protein (CRP) in the treatment group significantly decreased from 65.82 ± 81.31 mg/L to 14.03 ± 17.94 mg/L (P = 0.028), while in the control group, CRP decreased from 30.66 ± 47.78 mg/L to 8.17 ± 11.71 mg/L (P = 0.0049). Other inflammatory markers, such as procalcitonin (PCT), also showed corresponding changes. Conclusion: This study demonstrates that echocardiography combined with blood-related detection indicators has significant application prospects in the diagnosis and treatment of Kawasaki disease in children. This combined diagnostic approach not only helps improve the diagnostic accuracy and treatment efficacy of Kawasaki disease but also offers new insights for individualized treatment. Further promotion and in-depth research of this combined diagnostic strategy will contribute to optimizing the clinical management of Kawasaki disease in children, improving patient prognosis and quality of life.展开更多

In comparison...The results of biochemical indices in human blood show that there are significant difference in the population mean of these indices between the LREE high region in South Jiangxi, China and the control. In comparison with the normal region, the contents of total serum protein(TSP), albumin(AL), β globulin (β G), glutamic pyruvic transitanase (GPT), serium triglycerides (STG) and immunoglobulin(IgA) are manifested as low, but high cholesterol (CHO) in the LREE high region. These deviations may be related to the REE concentration and composition in food chains, and also are sex dependent. Certain blood indices (such as TSP) of different age groups in the LREE high region indicate that the influence of REE on males is a one way irreversible process while females show a strong ability of restoration.展开更多

[Method] A total of 480 one-day-old 817 broilers were selected. They were randomly divided into four groups with different paddings, and each group was in triplicate. The weights of broilers and feed were weighed weekly. The growth performance of broilers was determined. On day 30, the ammonia concentra- tions in broiler houses were determined. On day 35, 6 broilers were randomly se- lected from each group, and their vein blood was sampled. In the sampled vein blood, the concentrations of ammonia, glucose, globulin, serum total protein and urea nitrogen were determined. [Result] There were significant differences in ammo- nia concentration among broiler houses laid with different paddings （P〈0.05）. The ammonia concentration in group 1 was significantly lower than those in group 3 and group 4 （P〈0.05）. No significant difference was found in ammonia concentrations in broiler houses between group 2 and group 3 （P〉0.05）. The ammonia concentration in group 4 was significantly higher than those in group1, group 2 and group 3 （,0〈 0.05）. There were also significant differences in blood indicators among different groups （P〈0.05）. The blood ammonia, blood glucose and serum urea nitrogen con- centrations in group 1 were significantly lower than those in other groups （P〈0.05）, the serum total protein concentration was significantly higher than those in group 3 and group 4 （P〈0.05）, and the serum globulin concentration was significantly higher than those in group 2, group 3 and group 4 （P〈0.05）. Significant differences were observed in feed intake, body weight gain and slaughter weight between different groups （P〈0.05）, but there were no significant differences in feed to grain ratio （P〉 0.05）. [Conclusion] Under the experimental conditions, the padding of Chinese medicine residue showed better effect on reducing ammonia concentration in broiler house, which was conducive to play of production potential of broilers.展开更多

A total of 400 female Arbor Acres （AA） broiler breeders were studied. These female birds involved three experimental treatments and a control group with normal dietary energy diets （ND, 11.7 MJ of ME. kgt during the laying）. In treatments 2, 3 and 4, the energies of diets were 20%, 30% and 50% （LD20, LD30 and LD50） lower than those of the control, respectively. The study commenced at the beginning of the laying period when the total egg production reached 5% of the flock. All the broiler offspring were fed the same diets. The results showed that in low energy diets, offspring showed decreased 1-day-old weight, but 49-day-old weight was higher in LD20 diet （P〈0.05）. For offspring during days 1-49, the average daily gain （ADG） in LD20 group and the feed conversion ratio in LD50 group were improved as compared with those of the control （P〈0.05）. Compared with the control, abdominal fat percentage increased in 49-day-old offspring from LD30 diet （P〈0.05）; the fat content of breast muscle in offspring increased in broilers fed low energy diets （P〈0.05）. In 28-day-old offspring from breeders given LD20 and LD50 diets, liver fat percentages were higher compared with ND （P〈0.05）. The subcutaneous fat thickness in 28-day-old offspring from LD50 group and 49-day-old offspring from LD30 group was higher （P〈0.05）. On day 49, the serum cholesterol （CHO） of offspring from breeders fed LD20 diet and serum high-density lipoprotein （HDL） of offspring from breeders fed LD50 diet reduced compared with those of the control （P〈0.05）. In addition, a higher triiodothyronine （T3） content in serum was found in offspring from broiler breeders given LD20 and LD30 diets （P〈0.05）. Serum thyroxine （T4） in offspring significantly decreased with the decrease of diet energy （P〈0.05）. In conclusion, to a certain extent, dietary energy restriction in breeders could improve growth performance and promote lipid metabolism of offspring.展开更多
文摘Objective:To investigate the differential effects of different rivaroxaban dosing regimens on symptom relief,fluctuations in laboratory parameters,and medication safety in patients with stable pulmonary embolism(PE).Methods:This study enrolled 100 patients in the maintenance phase of PE who were treated at our hospital between January 2022 and December 2023.They were randomly divided into a control group and an observation group using a random number table,with 50 subjects in each group.The treatment period was uniformly set at 6 months.The control group received oral rivaroxaban 10 mg once daily,while the observation group received oral rivaroxaban 5 mg once daily.The study focused on comparing the two groups regarding the degree of clinical symptom relief,coagulation function parameters(including D-dimer levels,PT,and APTT),cardiac function markers(NT-proBNP),and drug-related adverse events.All data were processed using SPSS 26.0 statistical software.Measurement data are presented as mean±standard deviation,intergroup differences were verified by t-test,categorical variables were analyzed by chi-square test,and the statistical significance level was set at P<0.05.Results:After six months of treatment intervention,there was no significant difference in the overall relief of core clinical symptoms such as dyspnea and chest pain between the two groups.Regarding laboratory indicators,post-treatment D-dimer levels,prothrombin time,activated partial thromboplastin time,and NT-proBNP values were significantly optimized compared to baseline in both groups(P<0.05),but intergroup comparisons did not reach statistical significance.Notably,the overall incidence of bleeding events in the observation group was significantly lower than that in the control group(P<0.05),while there were no significant differences in the incidence rates of other adverse events between the two groups.Conclusion:In the maintenance phase treatment of pulmonary embolism,rivaroxaban 5 mg and 10 mg doses are equivalent in efficacy regarding improvement of clinical symptoms and blood indicators.However,the 5 mg dose significantly reduces the risk of bleeding,offers better safety,and is more suitable for long-term anticoagulation management in some high-risk populations.
文摘Objective: To analyze the effectiveness of blood test indicators in the differential diagnosis of anemia. Methods: Sixty patients diagnosed with anemia (disease group) from June 2021 to June 2024 were selected. Based on the type of disease, the group was subdivided into iron deficiency anemia (IDA) with 31 cases, hemolytic anemia (HA) with 11 cases, and aplastic anemia (AA) with 18 cases. Based on the severity of the disease, the group was divided into mild anemia (30 cases), moderate anemia (19 cases), and severe anemia (11 cases). Sixty healthy individuals (control group) were also included, and all underwent blood tests. Comparisons were made between the red blood cell (RBC) indicators of the disease group and the control group, the blood test indicators of different types of anemia, and the serum iron levels of varying severity of anemia. Results: Except for red cell distribution width (RDW), the RBC indicators in the disease group were lower than those in the control group (P < 0.05). Comparisons of RBC indicators among different types of anemia showed significant differences (P < 0.05). Serum iron levels varied significantly among different degrees of anemia severity (P < 0.05). Conclusion: Blood tests can detect anemia, distinguish types of anemia, and assess anemia severity, offering high diagnostic value.

文摘Background： Salmonella enterica serovar Enteritidis （SE）, as a major cause of foodborn illness, infects humans mainly through the egg. However, the symptom of laying hens usually is not typical and hard to diagnosis. In the present study, it is studied that the influences of SE infection on layers＇ performance, egg quality and blood biochemical indicators. It will help us to improve the strategy to control SE infection in commercial layers. One hundred layers at 20 wk of age were divided into 2 groups, 60 hens for experiment and others for control. The experiment group was fed with the dosage of 108 CFU SE per hen. The specific PCR was used to detect the deposition of SE. On the 8 d after SE infection, 10 hens from the control group and 30 hens from the experimenta group were slaughtered to detect the SE colonization. The production performance, egg quality and blood biochemical indices were also analyzed. Results： The results showed that the colonization rate of SE was highest in caecum contents （55.17%） and lowest in vagina （17.24%）. For the eggs the detection rate of SE was highest on the eggshell （80.00%） and lowest in yolk （18.81%）. SE infection had no significant influence on production performance and egg qualities （P 〉 0.05）. The difference of laying rate between the experimental and control groups was less than 0.30%, and both were approximately equal to 82.00%. The blood analysis showed that the aspartic aminotransferase （AST） and alanine aminotransferase （ALT） of experimental group was significantly higher than those of control group （P 〈 0.05）. For experimental and control groups AST values were 236.22 U/I and 211.84 U/I respectively, and ALT values were 32.19 U/I and 24.55 U/I. All of coefficients were less than 20%. The colonization of SE in organs increases the enzyme activities of AST and ALT in blood. Conclusions： SE in feed could invade the oviduct and infect the forming eggs. It significantly increased the concentration of ALT and AST in blood. However,SE infection was hard to be observed from the appearances of layer and egg. It might be a dangerous risk to human health.

文摘Objective: This study aims to explore the application of echocardiography combined with blood-related detection indicators in the diagnosis and treatment of Kawasaki disease in children, assessing the potential advantages of this combined diagnostic method for early diagnosis, disease monitoring, and evaluation of treatment efficacy, thereby providing more effective treatment strategies. Methods: The study included 50 children diagnosed with Kawasaki disease as the study group, and 50 children with upper respiratory infections as the control group. Both groups underwent echocardiographic examinations to assess cardiac structure and function, while monitoring changes in blood-related inflammatory markers. The differences in echocardiographic and blood-related indicators before and after treatment between the two groups were compared. Results: Echocardiography effectively assessed the cardiac structure and function of children with Kawasaki disease. It was found that the ejection fraction (EF) in the treatment group significantly decreased from 69.94 ± 5.93% before treatment to 65.70 ± 5.56% after treatment (P = 0.0019), while the control group showed no significant change (from 70.94 ± 6.27% to 69.18 ± 6.14%, P = 0.2073). The aortic diameter (AO) in the treatment group increased from 12.85 ± 2.77 mm to 13.17 ± 2.41 mm (P = 0.0000), while in the control group it decreased from 18.58 ± 6.66 mm to 17.64 ± 6.83 mm (P = 0.0000), indicating potential vascular remodeling. In terms of blood indicators, the C-reactive protein (CRP) in the treatment group significantly decreased from 65.82 ± 81.31 mg/L to 14.03 ± 17.94 mg/L (P = 0.028), while in the control group, CRP decreased from 30.66 ± 47.78 mg/L to 8.17 ± 11.71 mg/L (P = 0.0049). Other inflammatory markers, such as procalcitonin (PCT), also showed corresponding changes. Conclusion: This study demonstrates that echocardiography combined with blood-related detection indicators has significant application prospects in the diagnosis and treatment of Kawasaki disease in children. This combined diagnostic approach not only helps improve the diagnostic accuracy and treatment efficacy of Kawasaki disease but also offers new insights for individualized treatment. Further promotion and in-depth research of this combined diagnostic strategy will contribute to optimizing the clinical management of Kawasaki disease in children, improving patient prognosis and quality of life.
文摘BACKGROUND Severe hyperlipemia(SHLE)has an impact on the results of many kinds of laboratory tests.Complete blood count(CBC)examination by automated blood cell counter(ABCC)is a quick and convenient measurement for screening abnormalities of blood cells that are triggered by various pathogenic insults in disease diagnosis and for monitoring changes in the treatment of existing hematological conditions.However,CBC results are frequently affected by many intrinsic and extrinsic factors from blood samples,such as in the setting of hypergammaglobulinemia and certain anticoagulants.SHLE could also affect CBC results.CASE SUMMARY A 33-year-old Chinese male presented with painful foot numbness and abdominal pain.He was initially misdiagnosed as having a myeloproliferative neoplasm(MPN)because of the marked abnormalities in CBC examination by the ABCC.Morphological evaluation of the bone marrow smears and biopsy showed no evidence of MPN.Gene mutations in Breakpoint cluster regions-Abelson murine leukemia viral oncogene homologue 1(BCR-ABL1),Janus kinase 2(JAK2),calreticulin(CALR),myeloproliferative leukemia virus(MPL),and colony-stimulating factor 3 receptor(CSF3R)were negative.Having noticed the thick chylomicron layer on blood samples and the dramatically fluctuating CBC results,we speculated that the fat droplets formed by shaking the blood samples in the setting of SHLE were mistakenly identified as blood cells due to the limited parameters of ABCC.Therefore,we removed a large part of the chylomicron layer and then reexamined the CBC,and the CBC results,as we expected,differed significantly from that of the sample before the chylomicron layer was removed.These significant differences had been validated by the subsequently repeated laboratory tests by measuring dual blood samples that the chylomicron layer was removed in one sample and was not in another,and comparing the CBC results.Computerized tomography reexamination of the upper abdomen revealed an exudative lesion surrounding his pancreas.After intensive consultation,definitive diagnosis was made as recurrent pancreatitis,hyperlipemia and pseudoerythrocytosis.CONCLUSION SHLE may become a potential cause of misdiagnosis of hyperlipemia-related diseases as MPNs and the resultant mistreatment.It may also lead to the misinterpretation of transfusion indications in patients with hematological disorders who critically need blood transfusion for supportive treatment.
文摘BACKGROUND Millions of people have died of coronavirus disease 2019(COVID-19)due to severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)infection,and retrospective studies of the disease in local regions are necessary.AIM To characterize the epidemiological features and dynamic changes in blood biochemical indices for SARS-Co V-2-infected patients in Hebi,a representative city with a large floating population in North China.METHODS From January 25 to February 10,2020,the clinical data of patients who tested positive for SARS-Co V-2 by quantitative real-time polymerase chain reaction in Hebi city(China)were evaluated at admission,and laboratory data for hematologic parameters,inflammatory indices,coagulation function indices,liver function indices,blood lipid indices,renal function indices,myocardial enzyme activities and five blood biochemical markers of immunity were evaluated at admission,upon hospitalization and before discharge.RESULTS Sixteen confirmed COVID-19 patients developed pneumonia but were cured after adequate treatment.Fever and fatigue were the common symptoms.The most common laboratory abnormalities of patients at admission were leukopenia,eosinopenia,decreased percentage of eosinophils,elevated high sensitivity C-reactive protein and fibrinogen levels,hypoalbuminemia,mildly increased aspartate transferase activity and levels of bilirubin,and increased levels ofβ2-microglobulin.Importantly,aggravated liver dysfunction was detected in most patients,which may be partially attributed to virus infection as well as medicinal treatment.CONCLUSION This study provides several potential diagnostic markers and dynamic biochemical indices of disease progression to better prevent,diagnose and treat COVID-19 infection.
文摘The results of biochemical indices in human blood show that there are significant difference in the population mean of these indices between the LREE high region in South Jiangxi, China and the control. In comparison with the normal region, the contents of total serum protein(TSP), albumin(AL), β globulin (β G), glutamic pyruvic transitanase (GPT), serium triglycerides (STG) and immunoglobulin(IgA) are manifested as low, but high cholesterol (CHO) in the LREE high region. These deviations may be related to the REE concentration and composition in food chains, and also are sex dependent. Certain blood indices (such as TSP) of different age groups in the LREE high region indicate that the influence of REE on males is a one way irreversible process while females show a strong ability of restoration.

[Conclusion] Under the experimental conditions, the padding of Chinese medicine residue showed better effect on reducing ammonia concentration in broiler house, which was conducive to play of production potential of broilers.
文摘BACKGROUND Severe pneumonia is a common severe respiratory infection worldwide,and its treatment is challenging,especially for patients in the intensive care unit(ICU).AIM To explore the effect of communication and collaboration between nursing teams on the treatment outcomes of patients with severe pneumonia in ICU.METHODS We retrospectively analyzed 60 patients with severe pneumonia who were treated at the ICU of the hospital between January 1,2021 and December 31,2023.We compared and analyzed the respiratory mechanical indexes[airway resistance(Raw),mean airway pressure(mPaw),peak pressure(PIP)],blood gas analysis indexes(arterial oxygen saturation,arterial oxygen partial pressure,and oxygenation index),and serum inflammatory factor levels[C-reactive protein(CRP),procalcitonin(PCT),cortisol(COR),and high mobility group protein B1(HMGB1)]of all patients before and after treatment.RESULTS Before treatment,there was no significant difference in respiratory mechanics index and blood gas analysis index between 2 groups(P>0.05).However,after treatment,the respiratory mechanical indexes of patients in both groups were significantly improved,and the improvement of Raw,mPaw,plateau pressure,PIP and other indexes in the combined group after communication and collaboration with the nursing team was significantly better than that in the single care group(P<0.05).The serum CRP and PCT levels of patients were significantly decreased,and the difference was statistically significant compared with that of nursing group alone(P<0.05).The levels of serum COR and HMGB1 before and after treatment were also significantly decreased between the two groups.CONCLUSION The communication and collaboration of the nursing team have a significant positive impact on respiratory mechanics indicators,blood gas analysis indicators and serum inflammatory factor levels in the treatment of severe pneumonia patients in ICU.
文摘Background:Studies on animals have demonstrated that maternal iron deficiency anaemia(IDA)could result in decreased cochlear sensory hair cells and reduced amplitudes of distortion-product otoacoustic emissions(DPOAEs)of young guinea pigs.Thus,it is essential to study the functioning of cochlear hair cells using DPOAEs in human newborn babies with maternal IDA.The current study explores maternal IDA’s effect on DPOAEs in newborn babies.Method:A total of 110 newborn babies with gestational age≥34 weeks were considered and a‘betweensubjects’design was used.The participants were divided into 3 groups-“Normal”(61 babies without maternal IDA),“Mild”(28 babies with mild maternal IDA)and“Moderate”(21 babies with moderate maternal IDA).The cord blood was collected and the DPOAEs were recorded for each baby for a range of frequencies(1 k 8 kHz)and a range of intensities(7040 dB SPL in 10 dB steps).Results:The analysis of both DP-gram and DP input-output(I/O)function showed that there was no significant difference(p>0.05)across the normal,mild,and moderate groups in the overall presence of DPOAEs as well as the amplitude across frequencies or intensities(7040 dB SPL).Also,the overall correlation of RBC indices with DPOAE amplitude across frequencies as well as the slope of the I/O function showed no relationship.Conclusion:The current study concludes that there is no effect of late-term maternal IDA on the DPOAEs of newborn babies.

文摘The study was carried out to investigate the effects of maternal dietary energy restriction on growth performance, serum indices and fat deposition of offspring. A total of 400 female Arbor Acres （AA） broiler breeders were studied. These female birds involved three experimental treatments and a control group with normal dietary energy diets （ND, 11.7 MJ of ME. kgt during the laying）. In treatments 2, 3 and 4, the energies of diets were 20%, 30% and 50% （LD20, LD30 and LD50） lower than those of the control, respectively. The study commenced at the beginning of the laying period when the total egg production reached 5% of the flock. All the broiler offspring were fed the same diets. The results showed that in low energy diets, offspring showed decreased 1-day-old weight, but 49-day-old weight was higher in LD20 diet （P〈0.05）. For offspring during days 1-49, the average daily gain （ADG） in LD20 group and the feed conversion ratio in LD50 group were improved as compared with those of the control （P〈0.05）. Compared with the control, abdominal fat percentage increased in 49-day-old offspring from LD30 diet （P〈0.05）; the fat content of breast muscle in offspring increased in broilers fed low energy diets （P〈0.05）. In 28-day-old offspring from breeders given LD20 and LD50 diets, liver fat percentages were higher compared with ND （P〈0.05）. The subcutaneous fat thickness in 28-day-old offspring from LD50 group and 49-day-old offspring from LD30 group was higher （P〈0.05）. On day 49, the serum cholesterol （CHO） of offspring from breeders fed LD20 diet and serum high-density lipoprotein （HDL） of offspring from breeders fed LD50 diet reduced compared with those of the control （P〈0.05）. In addition, a higher triiodothyronine （T3） content in serum was found in offspring from broiler breeders given LD20 and LD30 diets （P〈0.05）. Serum thyroxine （T4） in offspring significantly decreased with the decrease of diet energy （P〈0.05）. In conclusion, to a certain extent, dietary energy restriction in breeders could improve growth performance and promote lipid metabolism of offspring.
