Based on the diagnostic criteria and stage classification of DR, the patients were divided into the non-DR(NDR) group and the PDR group. Thirty-six patients with cataract but no other ocular and systemic disease were included as non-diabetic controls. All the patients were subjected to the conventional clinical tests of corneal sensitivity, Schirmer I test, and corneal fluorescein staining. The non-invasive tear film break-up time(NIBUT) and tear interferometry were conducted by a Tearscope Plus. The morphology of corneal epithelia and nerve fibers was examined using the high-resolution confocal microscopy.RESULTS: The NDR group exhibited significantly declined corneal sensitivity and Schirmer I test value, as compared to the non-diabetic controls(P 【0.001). The PDR group showed significantly reduced corneal sensitivity, Schirmer I test value, and NIBUT in comparison to the non-diabetic controls(P 【0.001).Corneal fluorescein staining revealed the progressively injured corneal epithelia in the PDR patients. Moreover,significant decrease in the corneal epithelial density andmorphological abnormalities in the corneal epithelia and nerve fibers were also observed in the PDR patients.CONCLUSION: Ocular surface changes, including blunted corneal sensitivity, reduced tear secretion, tear film dysfunction, progressive loss of corneal epithelia and degeneration of nerve fibers, are common in type II diabetic patients, particularly in the diabetic patients with PDR. The corneal sensitivity, fluorescein staining scores,and the density of corneal epithelial cells and nerve fibers in the diabetic patients correlate with the duration of diabetes. Therefore, ocular surface of the patients with PDR should be examined regularly by conventional approaches and confocal microscopy to facilitate early diagnosis and treatment of keratopathy.展开更多

Sequence comparison and gene expression analysis among diverse primate species identified a human-specific splice form of KLK8 （type II） with preferential expression in the human brain, which may contribute to the origin of human cognition. To gain insights into the physiological and biochemical role of this novel form, we conducted functional analyses of human type II KLK8. Our results show that type II KLK8 is abundantly expressed in human embryonic stem cells and in embryo brain samples, suggesting a potential role in embryogenesis. There are dramatic expression variations in different individuals and brain regions, which is a reflection of its dynamic role in neural activities. Furthermore, the transcription start site （TSS） of KLK8 is tissue-specific, with a brain-specific TSS found in humans indicating functional specialization. Our in vitro biochemical assay shows that there is a type II-specific intermediate protein form, although the processed end-point enzymes are the same for both type 1 and type II KLK8, suggesting that the emergence of type II KLK8 in the human brain likciy leads to functional modifications of KLK8.展开更多

It is a single copy gene with a 4476 bp long ORF without intron. The deduced amino acid sequence shows strong homology to eukaryotic DNA Top 2. However, some distortions were found, such as six insertions in the ATPase domain and the central domain, a -100 aa longer central domain; a ~200 aa shorter C-terminal domain containing rich charged residues. These features revealed by comparing with Top 2 of the host, human, might be helpful in exploiting drug selectivity for antigiardial therapy. Phylogenetic analysis of eukaryotic enzymes showed that kinetoplastids, plants, fungi, and animals were monophyletic groups, and the animal and fungi lineages shared a more recent common ancestor than either did with the plant lineage; microsporidia grouped with fungi. However, unlike many previous phylogenetic analyses, the ''amitochondriate'' G. lamblia was not the earliest branch but diverged after mitochondriate kinetoplastids in our trees. Both the finding of typical eukaryotic type IIA topoisomerase and the phylogenetic analysis suggest G, lamblia is not possibly as primitive as was regarded before and might diverge after the acquisition of mitochondria. This is consistent with the recent discovery of mitochondrial remnant organelles in G. lamblia.展开更多

Methods Using polymerase chain reaction （PCR） and DNA sequencing techniques, the exons of AMH and AMHRII were analyzed in 27 OHSS patients （OHSS group） and 22 non-OHSS patients （control group） who were applied controlled ovarian hyper- stimulation （COH）. Single nucleotide polymorphisms （SNPs） were also analyzed. Results SNPs G〉 T at position 146 of AMH exon 1 and G〉 A at position 134 of AMH exon 2 showed significant differences between the OHSS group and control group （P〈0.05）. SNP G〉 T at position 303 of AMH exon 1 showed no significant difference between the OHSS group and control group （P〉0.05）. No SNP was detected from the AMHR H exons 1 to 11 in either groups. Conclusion Genetic polymorphisms in the AMH gene may be a cause of ovarian hypersensitivity to exogenous hormone stimulation and the development of OHSS.展开更多

The osteopetrosis of ADO2 has been attributed to hypofunctional osteoclasts. The mechanism underlying the abnormality in osteoclast function remains largely unknown. This study was designed to investigate gene mutations and osteoclast function in a case that was clinically diagnosed as ADO2. Genomic DNA was extracted from blood samples of this patient, and the 25 exons of CLCN7 were amplified. Peripheral blood from the ADO2 subject and a healthy age- and sex-matched control was used to evaluate osteoclastogenesis, osteoclast morphology, and bone resorption. Analysis of DNA from the patient showed a germline heterozygous missense mutation,c.1856C>T(p.P619L), in exon 20 of CLCN7. A similar homozygous mutation at this site was previously reported in a patient with autosomal recessive osteopetrosis. When cultured, the peripheral blood mononuclear cells(PBMCs) from the ADO2 patient spontaneously differentiated into mature osteoclasts in vitro. The ADO2 patient’s PBMCs formed enhanced, but heterogeneous, osteoclasts in both the presence and absence of macrophage-colony stimulating factor, and nuclear factor-?B ligand. Bone resorption was reduced in the ADO2 patient’s osteoclasts, which exhibited aberrant morphology and abnormal distribution of integrin avβ3. Gene analysis found increased c-fos expression and reduced Rho A and integrin beta 3expression in ADO2 cells. In conclusion, our data suggest that enhanced, heterogeneous osteoclast induction may be an intrinsic characteristic of ADO2.展开更多

Methods: 60 cases of inpatients were randomly and evenly divided into treatment group (conventional medication plus acupuncture) and control (conventional mediation) group. Plasma corticotropin releasing hormone (CRH), adrenocorticotropin hormone (ACTH) and corticosteroid (CS) contents before and after treatment were measured using radioimmunoassay (RIA) and compared with those of healthy subject group (n=30). Results: Plasma CRH, ACTH and CS levels in patients of both treatment group and control group at admission were significant higher than those of normal subject group (P<0.05). After treatment for 15～30 days, results showed that plasma CRH, ACTH and CS levels in both treatment and control groups lowered significantly in comparison with those of pre treatment (P<0.05 or 0.01); while those of treatment group were even more lower (being closer to the normal values) than those of control group (P<0.05 or 0.01). Conclusion: Acupuncture therapy can reduce the stress state of HPA in type II diabetes with concurrent acute cerebral infarction patients, i.e. regulate the neuroendocrine immunological net, which may be one of the mechanisms for acupuncture treatment of cerebral stroke.展开更多

Although extensive efforts have been made over the last decades in understanding the structures and functions of Prxs, type II Prxs in monocots are hardly studied. In this work, a monocot type II Prx gene homologue from Chinese wildrye（Leymus Chinensis）, designated as LcTpxII, was isolated and characterized. LcTpxII encoding a 162-amino acid protein contains a thioredoxin domain and a cysteine residue at position 51, suggesting that it is a member of the Prxs family. The LcTpxII is capable of decomposing H2O2 and protecting plasmid DNA from damage caused by ROS. The expression of LcTpxII in Chinese wildrye was induced by 400 mmol/L NaCl and 100 mmol/L Na2CO3 in the experiment. The overexpression of LcTpxII enhances the tolerance of transgenic yeast to 1.6 mol/L NaCl and 10 mmol/L Na2CO3.展开更多

This epidemic is elevating in increasing rates in Saudi Arabia. Thus, the study investigates a number of risk factors of Type II diabetes in Hail region, one of Saudi Arabia’s highest regions in diabetes records among adults. Data are collected using diabetic subjects from the Diabetes Registry Records in King Khalid Hospital at the city of Hail, Saudi Arabia, where 200 subjects’ records from 2014 to 2018 were included. A binary logistic regression was utilized to assess the association between age, gender, obesity, hypertension, family history, hypercholesterolemia, and hyperglyceridemia as risk factors and Type II diabetes. Some risk factors yielded statistical significant associations such as age (OR = 486.00 for 61 and older;OR = 468.00 for 51 - 60;and OR = 130.50 for 41 - 50;p-values ≤ 0.01), obesity (OR = 3.088;p-value ≤ 0.01), and hypertension (OR = 8.476;p-value ≤ 0.01), while gender, family history, hypercholesterolemia, and hyperglyceridemia were insignificant risk factors in our study. Proper intervention measures targeting diabetes risk factors may tackle or delay this public health issue.展开更多

Each group was continuously incubated for 3 h after administration of Iso or/and H2O2. The intracellular SP-A and the SP-A of cultured medium were measured with an enzyme-linked immunosorbent assay(ELISA).Results Iso significantly decreased SP-A content of cultured medium and the intracellular,and aggravated the decrease of SP-A content induced by H2O2 in a dose-dependent manner.Conclusion Iso itself may decrease SP-A synthesis of AT II cells in vitro,and aggravate the damage of AT II cells especially under peroxidation condition.展开更多

CA plays a crucial role in CO<sub>2</sub> transport, acid-base balance, and in linking local acidosis to O<sub>2</sub> unloading from hemoglobin and also facilitates lactate shuttling across the monocarboxylate transporters (MCT). The study aimed to investigate the influence of hyperglycemia on erythrocyte carbonic anhydrase activity and lactic acid in type II diabetic patients. Method: Red blood cell carbonic anhydrase activity was determined in washed lysed-hemolysate by the action of the enzyme on the substrate p-nitrophenyl acetate. The absorbance of released p-nitrophenol was recorded at 345 nm. Glycated Hemoglobin was determined by ion exchange method (Spectrum Diagnostic Kit). Blood glucose, lactate, cholesterol and triglyceride were determined using Accutrend GCT meter (Roche, Germany) with cobias<sup>®</sup> test strips. Results: The present study showed that hyperglycemia significantly (p < 0.05) increased both erythrocyte carbonic anhydrase activity and blood lactate level in type II diabetic patients. Conclusion: We may conclude that hyperglycemia may be responsible for the increased activity of carbonic anhydrase activity and blood lactate concentration.展开更多

Additionally, sleep disorders have been reported to aggravate diabetes due to decreased glucose metabolism and elevated cortisol levels as well as it can increase the risk for the development of diabetes. Objectives: To assess the sleep quality and its determinants and impact on glycemic control of type II diabetic patients. Methods: A cross sectional study was adopted among a representative sample of patients diagnosed with type II Diabetes seen in Prince Mansour Military Hospital Diabetic Center in Taif throughout the study period (March-July 2021). A self-administered questionnaire was utilized in the present study including 5 main parts: demographic data of the patients, medical and social history, the Pittsburgh Sleep Quality Index (PSQI) to assess the subjective sleep quality, weight and height measurements and the most recent glycated hemoglobin (HbA1c) level. Results: The study included 270 type II diabetic patients out of a targeted 282 with a response rate of 95.7%. Most of them aged either between 51 and 60 years (34.8%) or over 60 years (42%). Females represent 63% of them. Majority of patients (87.8%) had HbA1c ≥ 7%, indicating uncontrolled blood glucose levels. Overall, poor sleep quality, based on PSQI was observed among 41.1% of type II diabetic patients. Results of multivariate logistic regression analysis revealed that compared to patients whose income was lower than 5000 SR/month, those with income of 50,001 - 1000 and >15,000 SR/month were at lower significant risk for having poor sleep (Adjusted odds ratio “AOR” = 0.44, 95% confidence interval “CI” = 0.22 - 0.86, p = 0.016 and AOR = 0.21, 95% CI = 0.06 - 0.77, p = 0.019;respectively). Opposed to diabetic patients with a duration of less than one year of DM, those with a duration exceeding 10 years were at almost 6-folds higher risk for poor sleep quality (AOR = 6.39, 95% CI = 1.12 - 36.43, p = 0.037). Patients with a history of social stressors were at a higher significant risk for poor sleep quality compared to those without such a history (AOR = 4.99, 95% CI = 1.71 - 14.67, p = 0.003). Conclusion: A considerable proportion of type II diabetic patients attending the diabetic center, Prince Manasour Military hospital in Taif, Kingdom of Saudi Arabia expressed poor sleep quality. However, there was no association between glycemic control level and poor sleep quality.展开更多

Articular cartilage was isolated from dissected porcine knee joint n = 12. Isolated cells were plated as monolayers at a density of 1 × 105 cells/well in 12-well culture plates and incubated at 37℃ in a humid atmosphere of 5% carbon dioxide and 95% air. Cell cultures were treated for four days with various concentrations of bone morphogenetic protein-7 and resveratroL Cells were then collected and analysed for collagen type II expression by real time polymerase chain reaction and protein level quantification by enzyme-linked immunosorbent assay. Cartilage tissue sections were localised for collagen type II by immunohistochemistry. Moreover, resveratrol and bone morphogenetic protein-7 effects on cartilage matrix contents were analysed by histology. Resveratrol and bone morphogenetic protein-7 stimulates expression of collagen type II mRNA and protein level accumulation in the surface zone and middle zone at 50μM ＋ 300 ng/ml （RSV ＋ BMP-7）. Immunohistochemistry results confirmed the presence of collagen type II on articular cartilage. Histological tissue sections confirmed that chondrocytes were obtained from different zones of articular cartilage. The study suggests that a combination of bone morphogenetic protein-7 and resveratrol up-regulate the expression and synthesis of collagen type II.展开更多

Methods: A 26-year-old female patient was diagnosed with type II ODV with macular edema (ME). The information was obtained by complete medical and ophthalmic history taking and a detailed ophthalmic examination at the initial and follow-up visits. Functional and morphological outcomes at baseline, 1 week and 1 month following IVR+SS injections, are presented. Results: Best-corrected visual acuity (BCVA) improved from 78 letters (ETDRS) at baseline to 90 letters at 1-week follow-up and maintained stable through 1-month follow-up. Central retinal thickness (CRT) measured by optical coherence tomography (OCT) decreased from 465 μm at baseline to 240 μm at 1-week follow-up and to 226 μm at 1-month follow-up. Mean deviation (MD) measured by perimetry increased from ?5.17 dB to ?4.59 dB and to ?4.29 dB, respectively. Fluorescein angiography (FFA) showed that the initial macular edema at baseline disappeared while the arm-retina circulation time (ART) was also greatly shortened when compared to the baseline. Electroretinogram (ERG) measured at 1-month follow-up demonstrated an overall improvement of the retinal function after the injection. No ocular or systemic side effects were detected. Conclusions: IVR+SS injection may lead to resolution of the associated ME and improve the retina morphologically as well as functionally.

文摘Epithelial-mesenchymal transition(EMT)plays an irreplaceable role in the development of silicosis.However,molecular mechanisms of EMT induced by silica exposure still remain to be addressed.Herein,metabolic profiles of human alveolar type II epithelial cells(A549 cells)exposed directly to silica were characterized using non-targeted metabolomic approaches.A total of 84 differential metabolites(DMs)were identified in silica-treated A549 cells undergoing EMT,which were mainly enriched in metabolisms of amino acids(e.g.,glutamate,alanine,aspartate),purine metabolism,glycolysis,etc.The number of DMs identified in the A549 cells obviously increased with the elevated exposure concentration of silica.Remarkably,glutamine catabolism was significantly promoted in the silica-treated A549 cells,and the levels of related metabolites(e.g.,succinate)and enzymes(e.g.,α-ketoglutarate(α-KG)dehydrogenase)were substantially up-regulated,with a preference toα-KG pathway.Supplementation of glutamine into the cell culture could substantially enhance the expression levels of both EMT-related markers and Snail(zinc finger transcription factor).Our results suggest that the EMT of human alveolar epithelial cells directly induced by silica can be essential to the development of silicosis.

文摘AIM: To detect and analyze the changes on ocular surface and tear function in type II diabetic patients with proliferative diabetic retinopathy(PDR), an advanced stage of diabetic retinopathy(DR), using conventional ophthalmic tests and the high-resolution laser scanning confocal microscopy.METHODS: Fifty-eight patients with type II diabetes were selected. Based on the diagnostic criteria and stage classification of DR, the patients were divided into the non-DR(NDR) group and the PDR group. Thirty-six patients with cataract but no other ocular and systemic disease were included as non-diabetic controls. All the patients were subjected to the conventional clinical tests of corneal sensitivity, Schirmer I test, and corneal fluorescein staining. The non-invasive tear film break-up time(NIBUT) and tear interferometry were conducted by a Tearscope Plus. The morphology of corneal epithelia and nerve fibers was examined using the high-resolution confocal microscopy.RESULTS: The NDR group exhibited significantly declined corneal sensitivity and Schirmer I test value, as compared to the non-diabetic controls(P 【0.001). The PDR group showed significantly reduced corneal sensitivity, Schirmer I test value, and NIBUT in comparison to the non-diabetic controls(P 【0.001).Corneal fluorescein staining revealed the progressively injured corneal epithelia in the PDR patients. Moreover,significant decrease in the corneal epithelial density andmorphological abnormalities in the corneal epithelia and nerve fibers were also observed in the PDR patients.CONCLUSION: Ocular surface changes, including blunted corneal sensitivity, reduced tear secretion, tear film dysfunction, progressive loss of corneal epithelia and degeneration of nerve fibers, are common in type II diabetic patients, particularly in the diabetic patients with PDR. The corneal sensitivity, fluorescein staining scores,and the density of corneal epithelial cells and nerve fibers in the diabetic patients correlate with the duration of diabetes. Therefore, ocular surface of the patients with PDR should be examined regularly by conventional approaches and confocal microscopy to facilitate early diagnosis and treatment of keratopathy.
文摘Kallikrein 8 （KLK8） is a serine protease functioning in the central nervous system, and essential in many aspects of neuronal activities. Sequence comparison and gene expression analysis among diverse primate species identified a human-specific splice form of KLK8 （type II） with preferential expression in the human brain, which may contribute to the origin of human cognition. To gain insights into the physiological and biochemical role of this novel form, we conducted functional analyses of human type II KLK8. Our results show that type II KLK8 is abundantly expressed in human embryonic stem cells and in embryo brain samples, suggesting a potential role in embryogenesis. There are dramatic expression variations in different individuals and brain regions, which is a reflection of its dynamic role in neural activities. Furthermore, the transcription start site （TSS） of KLK8 is tissue-specific, with a brain-specific TSS found in humans indicating functional specialization. Our in vitro biochemical assay shows that there is a type II-specific intermediate protein form, although the processed end-point enzymes are the same for both type 1 and type II KLK8, suggesting that the emergence of type II KLK8 in the human brain likciy leads to functional modifications of KLK8.

文摘The genes encoding type II DNA topoisomerases were investigated in Giardia lamblia genome, and a type IIA gene,GlTop 2 was identified. It is a single copy gene with a 4476 bp long ORF without intron. The deduced amino acid sequence shows strong homology to eukaryotic DNA Top 2. However, some distortions were found, such as six insertions in the ATPase domain and the central domain, a -100 aa longer central domain; a ~200 aa shorter C-terminal domain containing rich charged residues. These features revealed by comparing with Top 2 of the host, human, might be helpful in exploiting drug selectivity for antigiardial therapy. Phylogenetic analysis of eukaryotic enzymes showed that kinetoplastids, plants, fungi, and animals were monophyletic groups, and the animal and fungi lineages shared a more recent common ancestor than either did with the plant lineage; microsporidia grouped with fungi. However, unlike many previous phylogenetic analyses, the ''amitochondriate'' G. lamblia was not the earliest branch but diverged after mitochondriate kinetoplastids in our trees. Both the finding of typical eukaryotic type IIA topoisomerase and the phylogenetic analysis suggest G, lamblia is not possibly as primitive as was regarded before and might diverge after the acquisition of mitochondria. This is consistent with the recent discovery of mitochondrial remnant organelles in G. lamblia.
文摘Inositol polyphosphate-4-phosphatase type II(INPP4B)is a newly discovered PI(3,4,5)P3 phosphatase.Many studies have revealed that INPP4B is upregulated or downregulated in tumors of the digestive system,and the abnormal expression of INPP4B may be attributed to the occurrence,development,and prognosis of tumors of the digestive system.This paper reviews studies on the correlations between INPP4B and digestive system tumors and the roles of INPP4B in the development of different tumors to provide a theoretical basis for further research on its molecular mechanism and clinical application."INPP4B"and"tumor"were searched as key words in PubMed and in the CNKI series full text database retrieval system from January 2000 to August 2023.A total of 153 Englishlanguage studies and 30 Chinese-language studies were retrieved.The following enrollment criteria were applied:(1)Studies contained information on the biological structure and functions of INPP4B;(2)studies covered the influence of abnormal expression of INPP4B in digestive system tumors;and(3)studies covered the role of INPP4B in the diagnosis,treatment,and prognosis of digestive system tumors.After excluding the literature irrelevant to this study,61 papers were finally included in the analysis.INPP4B expression is low in gastric cancer,colon cancer,pancreatic cancer,and liver cancer but it has high expression in esophageal cancer,colon cancer,pancreatic cancer,and gallbladder cancer.INPP4B is involved in the occurrence and development of digestive system tumors through the regulation of gene expression and signal transduction.The abnormal expression of INPP4B plays an important role in the development of digestive system tumors.Studies on INPP4B provide new molecular insights for the diagnosis,treatment,and prognosis evaluation of digestive system tumors.

文摘Objective To explore the association of genetic polymorphisms in the genes encoding the anti-Miillerian hormone （AMH） and its type H receptor （AMHRII） with ovarian hyperstimulation syndrome （OHSS）. Methods Using polymerase chain reaction （PCR） and DNA sequencing techniques, the exons of AMH and AMHRII were analyzed in 27 OHSS patients （OHSS group） and 22 non-OHSS patients （control group） who were applied controlled ovarian hyper- stimulation （COH）. Single nucleotide polymorphisms （SNPs） were also analyzed. Results SNPs G〉 T at position 146 of AMH exon 1 and G〉 A at position 134 of AMH exon 2 showed significant differences between the OHSS group and control group （P〈0.05）. SNP G〉 T at position 303 of AMH exon 1 showed no significant difference between the OHSS group and control group （P〉0.05）. No SNP was detected from the AMHR H exons 1 to 11 in either groups. Conclusion Genetic polymorphisms in the AMH gene may be a cause of ovarian hypersensitivity to exogenous hormone stimulation and the development of OHSS.

文摘Type II autosomal dominant osteopetrosis(ADO2), which is the most common form of osteopetrosis, is caused by heterozygous mutations in the chloride channel 7(CLCN7) gene. The osteopetrosis of ADO2 has been attributed to hypofunctional osteoclasts. The mechanism underlying the abnormality in osteoclast function remains largely unknown. This study was designed to investigate gene mutations and osteoclast function in a case that was clinically diagnosed as ADO2. Genomic DNA was extracted from blood samples of this patient, and the 25 exons of CLCN7 were amplified. Peripheral blood from the ADO2 subject and a healthy age- and sex-matched control was used to evaluate osteoclastogenesis, osteoclast morphology, and bone resorption. Analysis of DNA from the patient showed a germline heterozygous missense mutation,c.1856C>T(p.P619L), in exon 20 of CLCN7. A similar homozygous mutation at this site was previously reported in a patient with autosomal recessive osteopetrosis. When cultured, the peripheral blood mononuclear cells(PBMCs) from the ADO2 patient spontaneously differentiated into mature osteoclasts in vitro. The ADO2 patient’s PBMCs formed enhanced, but heterogeneous, osteoclasts in both the presence and absence of macrophage-colony stimulating factor, and nuclear factor-?B ligand. Bone resorption was reduced in the ADO2 patient’s osteoclasts, which exhibited aberrant morphology and abnormal distribution of integrin avβ3. Gene analysis found increased c-fos expression and reduced Rho A and integrin beta 3expression in ADO2 cells. In conclusion, our data suggest that enhanced, heterogeneous osteoclast induction may be an intrinsic characteristic of ADO2.
文摘Patients with type II diabetes mellitus(T2DM)and hypertension(HTN)are at increased threat for long experiencing various problems related to medicine as they frequently received different medications for managing their condition.Recently,there were no studies done locally on drug-related problems(DRPs)among T2DM patients with HTN.Thus,this study aims to assess the DRPs among T2DM patients with HTN admitted at Kibuye Referral Hospital(KRH).DRPs were drug safety problems,drug effectiveness problems and other drug problems.Methods:A retrospective cross-sectional study involved patients'files with T2DM and HTN,who were admitted at KRH from January 2013 to December 2017.The identification and classification of DRPs were based on pharmaceutical care network Europe(PCNE)classification system version 8.02.A simple random sampling technique was used to choose study participants from the target population.Data that met inclusion and exclusion criteria were analyzed using STATA version 13.The Fisher exact test(bivariate analysis)and logistic regression(multivariate)were used to test association and p-value≤0.05 was considered as statistically significant.An adjusted odd ratio(AOR)with a confidence interval(CI)of 95% was determined using binary logistic regression.Results:Findings revealed that the prevalence of DRPs was 81.29%(313/385)and most of them each patient had at least two DRPs(69.05%).The patients aged above 55 years old were more likely to develop DRPs than those with age below 35 years(AOR=1.2;P=0.02;95%CI:0.2-2.3).Nevertheless,there was no significant association between DRPs and middle age(between 35 and 54 age of old).The patients who consumed more than or equal to 5 drugs were 2.4 times more likely to develop DRPs than those who took the number of medicines less than 5(AOR=15.4;P<0.001;95%CI:8.8-26.8).Also,traditional medicines use(AOR=1.9;P=0.016;95%CI:1.1-3.5)and having drug-related complication(AOR=2.4;P<0.001;95%CI:1.9-3)had shown significant associations.The total causes of DRPs identified were 1626 and most causes of DRPs were arisen from drug use(45.01%)and prescribing(37.83%).The drug/dose selections were the most frequent causes of DRPs(36.97%).Conclusion:Since the prevalence of DRPs were relatively high,various factors influencing DRPs were established and most causes of DRPs were arising from drug use&drug prescribing among T2DM patients with HTN.Early detection needed to enhance patient’s life quality.Conducting studies in other hospitals needed to establish the national planning of DRPs to eradicate DRPs among patients T2DM with HTN.
文摘Objective: To observe the effect of acupuncture on the contents of stress hormones of the hypothalamus pituitary adrenal axis (HPA) in treatment of type II diabetes with concurrent acute cerebral infarction patients. Methods: 60 cases of inpatients were randomly and evenly divided into treatment group (conventional medication plus acupuncture) and control (conventional mediation) group. Plasma corticotropin releasing hormone (CRH), adrenocorticotropin hormone (ACTH) and corticosteroid (CS) contents before and after treatment were measured using radioimmunoassay (RIA) and compared with those of healthy subject group (n=30). Results: Plasma CRH, ACTH and CS levels in patients of both treatment group and control group at admission were significant higher than those of normal subject group (P<0.05). After treatment for 15～30 days, results showed that plasma CRH, ACTH and CS levels in both treatment and control groups lowered significantly in comparison with those of pre treatment (P<0.05 or 0.01); while those of treatment group were even more lower (being closer to the normal values) than those of control group (P<0.05 or 0.01). Conclusion: Acupuncture therapy can reduce the stress state of HPA in type II diabetes with concurrent acute cerebral infarction patients, i.e. regulate the neuroendocrine immunological net, which may be one of the mechanisms for acupuncture treatment of cerebral stroke.

文摘Peroxiredoxins（Prxs） are a large family of antioxidant enzymes of various types that take part in signal transduction via decomposing reactive oxygen species（ROS）. Although extensive efforts have been made over the last decades in understanding the structures and functions of Prxs, type II Prxs in monocots are hardly studied. In this work, a monocot type II Prx gene homologue from Chinese wildrye（Leymus Chinensis）, designated as LcTpxII, was isolated and characterized. LcTpxII encoding a 162-amino acid protein contains a thioredoxin domain and a cysteine residue at position 51, suggesting that it is a member of the Prxs family. The LcTpxII is capable of decomposing H2O2 and protecting plasmid DNA from damage caused by ROS. The expression of LcTpxII in Chinese wildrye was induced by 400 mmol/L NaCl and 100 mmol/L Na2CO3 in the experiment. The overexpression of LcTpxII enhances the tolerance of transgenic yeast to 1.6 mol/L NaCl and 10 mmol/L Na2CO3.
文摘Osteoarthritis(OA)of the knee is a common degenerative articular disorder and is one of the main causes of pain and functional disability.Cartilage damage is frequently linked to elevated osteoarthritis incidence.Supercritical carbon dioxide(scCO_(2))decellularized cartilage graft produced from the porcine cartilage is an ideal candidate for cartilage tissue engineering.In the present study,we derived collagen type II(Col II)solution from the scCO_(2) decellularized porcine cartilage graft(dPCG)and compared its efficacy with hyaluronic acid(HA)in the surgical medial meniscectomy(MNX)induced post-traumatic osteoarthritis(PTOA)model.Dose-dependent attenuation of the OA(12.3±0.8)progression was observed in the intra-articular administration of Col II solution(7.3±1.2)which significantly decreased the MNX-induced OA symptoms similar to HA.The pain of the OA group(37.4±2.7)was attenuated dose-dependently by Col II solution(45.9±4.1)similar to HA(43.1±3.5)as evaluated by a capacitance meter.Micro-CT depicted a dose-dependent attenuation of articular cartilage damage by the Col II solution similar to HA treatment.A significant(p<0.001)dose-dependent elevation in the bone volume was also observed in Col II solution-treated OA animals.The protective competence of Col II solution on articular cartilage damage is due to its significant(p<0.001)increase in the expression of type II collagen,aggrecan and SOX-9 similar to HA.To conclude,intra-articular adminis-tration of type II collagen solution and HA reestablished the injured cartilage and decreased osteoarthritis progression in the experimental PTOA model.
文摘BACKGROUND Congenital fiber-type disproportion(CFTD)is a form of congenital myopathy.CFTD is rare,especially when presenting in patients with critical illnesses.Here,we report a case of CFTD presenting with type II respiratory failure after delivery and provide a review of the literature on CFTD.CASE SUMMARY A 30-year-old woman was admitted to the obstetrics department of our hospital with premature rupture of the fetal membrane and with 7 h of regular contractions.After delivery,the patient experienced a refractory type II respiratory failure.Physical examination along with diagnostic procedures such as electromyography and biopsy confirmed CFTD.Use of invasive ventilator followed by intermittent use of noninvasive ventilator attenuated her symptoms.The patient recovered after ventilator-assisted respiration and was weaned off the noninvasive ventilator on the seventh day postpartum.CONCLUSION Congenital myopathy should be considered a differential diagnosis for type II respiratory failures that cannot be attributed to other diseases.
文摘Type II diabetes is a global health concern. This epidemic is elevating in increasing rates in Saudi Arabia. Thus, the study investigates a number of risk factors of Type II diabetes in Hail region, one of Saudi Arabia’s highest regions in diabetes records among adults. Data are collected using diabetic subjects from the Diabetes Registry Records in King Khalid Hospital at the city of Hail, Saudi Arabia, where 200 subjects’ records from 2014 to 2018 were included. A binary logistic regression was utilized to assess the association between age, gender, obesity, hypertension, family history, hypercholesterolemia, and hyperglyceridemia as risk factors and Type II diabetes. Some risk factors yielded statistical significant associations such as age (OR = 486.00 for 61 and older;OR = 468.00 for 51 - 60;and OR = 130.50 for 41 - 50;p-values ≤ 0.01), obesity (OR = 3.088;p-value ≤ 0.01), and hypertension (OR = 8.476;p-value ≤ 0.01), while gender, family history, hypercholesterolemia, and hyperglyceridemia were insignificant risk factors in our study. Proper intervention measures targeting diabetes risk factors may tackle or delay this public health issue.

Conclusion: It can be concluded from the clinical test that Daan and Biot Herpes Simplex Virus (HSV) Type II Nuc- leic Acid Test Kits are reliable, accurate, safe, convenient for use, stable and high-value in the clinical application.
文摘Objective To explore the influence of isoflurane(Iso) on the synthesis of surfactant-related protein(SP-A) of alveolar type II cells(AT II cells) cultured in primary and injured by hydrogen peroxide(H2O2).Methods AT II cells were isolated from adult SD rats and used for experiments after 32h in primary culture and randomized into six groups: control group,0.28 mM Iso group,2.8mM Iso group,75 μM H2O2 group,75 μM H2O2 +0.28 mM Iso group and 75 μM H2O2 +2.8 mM Iso group. Each group was continuously incubated for 3 h after administration of Iso or/and H2O2. The intracellular SP-A and the SP-A of cultured medium were measured with an enzyme-linked immunosorbent assay(ELISA).Results Iso significantly decreased SP-A content of cultured medium and the intracellular,and aggravated the decrease of SP-A content induced by H2O2 in a dose-dependent manner.Conclusion Iso itself may decrease SP-A synthesis of AT II cells in vitro,and aggravate the damage of AT II cells especially under peroxidation condition.
文摘Background: Carbonic anhydrase (CA) is a ubiquitous enzyme catalyzing the reversible hydration of CO<sub>2</sub> to and H<sup>+</sup>. CA plays a crucial role in CO<sub>2</sub> transport, acid-base balance, and in linking local acidosis to O<sub>2</sub> unloading from hemoglobin and also facilitates lactate shuttling across the monocarboxylate transporters (MCT). The study aimed to investigate the influence of hyperglycemia on erythrocyte carbonic anhydrase activity and lactic acid in type II diabetic patients. Method: Red blood cell carbonic anhydrase activity was determined in washed lysed-hemolysate by the action of the enzyme on the substrate p-nitrophenyl acetate. The absorbance of released p-nitrophenol was recorded at 345 nm. Glycated Hemoglobin was determined by ion exchange method (Spectrum Diagnostic Kit). Blood glucose, lactate, cholesterol and triglyceride were determined using Accutrend GCT meter (Roche, Germany) with cobias<sup>®</sup> test strips. Results: The present study showed that hyperglycemia significantly (p < 0.05) increased both erythrocyte carbonic anhydrase activity and blood lactate level in type II diabetic patients. Conclusion: We may conclude that hyperglycemia may be responsible for the increased activity of carbonic anhydrase activity and blood lactate concentration.
文摘Background: Experimental and observational studies have indicated that poor sleep quantity and quality are associated with an increased risk of chronic diseases including insulin resistance. Additionally, sleep disorders have been reported to aggravate diabetes due to decreased glucose metabolism and elevated cortisol levels as well as it can increase the risk for the development of diabetes. Objectives: To assess the sleep quality and its determinants and impact on glycemic control of type II diabetic patients. Methods: A cross sectional study was adopted among a representative sample of patients diagnosed with type II Diabetes seen in Prince Mansour Military Hospital Diabetic Center in Taif throughout the study period (March-July 2021). A self-administered questionnaire was utilized in the present study including 5 main parts: demographic data of the patients, medical and social history, the Pittsburgh Sleep Quality Index (PSQI) to assess the subjective sleep quality, weight and height measurements and the most recent glycated hemoglobin (HbA1c) level. Results: The study included 270 type II diabetic patients out of a targeted 282 with a response rate of 95.7%. Most of them aged either between 51 and 60 years (34.8%) or over 60 years (42%). Females represent 63% of them. Majority of patients (87.8%) had HbA1c ≥ 7%, indicating uncontrolled blood glucose levels. Overall, poor sleep quality, based on PSQI was observed among 41.1% of type II diabetic patients. Results of multivariate logistic regression analysis revealed that compared to patients whose income was lower than 5000 SR/month, those with income of 50,001 - 1000 and >15,000 SR/month were at lower significant risk for having poor sleep (Adjusted odds ratio “AOR” = 0.44, 95% confidence interval “CI” = 0.22 - 0.86, p = 0.016 and AOR = 0.21, 95% CI = 0.06 - 0.77, p = 0.019;respectively). Opposed to diabetic patients with a duration of less than one year of DM, those with a duration exceeding 10 years were at almost 6-folds higher risk for poor sleep quality (AOR = 6.39, 95% CI = 1.12 - 36.43, p = 0.037). Patients with a history of social stressors were at a higher significant risk for poor sleep quality compared to those without such a history (AOR = 4.99, 95% CI = 1.71 - 14.67, p = 0.003). Conclusion: A considerable proportion of type II diabetic patients attending the diabetic center, Prince Manasour Military hospital in Taif, Kingdom of Saudi Arabia expressed poor sleep quality. However, there was no association between glycemic control level and poor sleep quality.
文摘This study aimed to investigate the effects of resveratrol and bone morphogenetic protein 7 on type II collagen from superficial and middle zone of porcine articular chondrocytes. Articular cartilage was isolated from dissected porcine knee joint n = 12. Isolated cells were plated as monolayers at a density of 1 × 105 cells/well in 12-well culture plates and incubated at 37℃ in a humid atmosphere of 5% carbon dioxide and 95% air. Cell cultures were treated for four days with various concentrations of bone morphogenetic protein-7 and resveratroL Cells were then collected and analysed for collagen type II expression by real time polymerase chain reaction and protein level quantification by enzyme-linked immunosorbent assay. Cartilage tissue sections were localised for collagen type II by immunohistochemistry. Moreover, resveratrol and bone morphogenetic protein-7 effects on cartilage matrix contents were analysed by histology. Resveratrol and bone morphogenetic protein-7 stimulates expression of collagen type II mRNA and protein level accumulation in the surface zone and middle zone at 50μM ＋ 300 ng/ml （RSV ＋ BMP-7）. Immunohistochemistry results confirmed the presence of collagen type II on articular cartilage. Histological tissue sections confirmed that chondrocytes were obtained from different zones of articular cartilage. The study suggests that a combination of bone morphogenetic protein-7 and resveratrol up-regulate the expression and synthesis of collagen type II.
文摘Objectives:To explore the application of health management in patients with type II diabetes and to analyze and compare the incidence of chronic complications.Methods:the relevant research work was carried out in our hospital.During September 2018 to September 2019,100 patients with type II diabetes were randomly divided into two groups:one group was given routine nursing intervention,the other group was given health management,and they were named control group and experimental group respectively.Each group had 50 patients,the influence of different nursing methods on the incidence of chronic complications in patients was explored.Results:In the one-year followup results,the corresponding complications of patients mainly include cardiovascular disease,kidney disease,cerebrovascular disease,fundus disease and peripheral neuropathy.The incidence of complications in the experimental group is 10.00%,while that in the control group is 32.00%.in comparison,the incidence in the experimental group is lower,and the data difference between the two group is small(P<0.05),which exists significance.Conclusion:The application of health management method in type II diabetes has significant effect,which can reduce the incidence of chronic complications,improve the quality of life of patients,and has positive significance for clinical development.
文摘Objectives: To present the effect of intravitreal ranibizumab (IVR) therapy combined with sulfotanshinone sodium (SS) injection in a patient suffering from type II optic disc vasculitis (ODV). Methods: A 26-year-old female patient was diagnosed with type II ODV with macular edema (ME). The information was obtained by complete medical and ophthalmic history taking and a detailed ophthalmic examination at the initial and follow-up visits. Functional and morphological outcomes at baseline, 1 week and 1 month following IVR+SS injections, are presented. Results: Best-corrected visual acuity (BCVA) improved from 78 letters (ETDRS) at baseline to 90 letters at 1-week follow-up and maintained stable through 1-month follow-up. Central retinal thickness (CRT) measured by optical coherence tomography (OCT) decreased from 465 μm at baseline to 240 μm at 1-week follow-up and to 226 μm at 1-month follow-up. Mean deviation (MD) measured by perimetry increased from ?5.17 dB to ?4.59 dB and to ?4.29 dB, respectively. Fluorescein angiography (FFA) showed that the initial macular edema at baseline disappeared while the arm-retina circulation time (ART) was also greatly shortened when compared to the baseline. Electroretinogram (ERG) measured at 1-month follow-up demonstrated an overall improvement of the retinal function after the injection. No ocular or systemic side effects were detected. Conclusions: IVR+SS injection may lead to resolution of the associated ME and improve the retina morphologically as well as functionally. To our knowledge, this is the first case of a type II ODV benefiting from treatment with IVR+SS injection. The observed results warrant further investigation.
