Objective: To study diagnostic and predictive value of levels of high sensitive C reactive protein (hsCRP) and cystatin C (CysC) for acute coronary syndrome (ACS) in aged patients.Methods: A total of 60 ACS patients (ACS group) treated in our hospital and 60 healthy subjects (healthy control group) undergoing physical examination during Dec 2013 to Sep 2015 were randomly selected.Serum levels of hsCRP and CysC, and abnormal rates of hsCRP and CysC were measured and compared between two groups.Results: Compared with healthy control group, there were significant rise in serum levels of hsCRP[(3.02±1.13) mg/L vs.(7.95±2.38) mg/L]and CysC[(0.75±0.11) μg/ml vs.(1.35±0.43) μg/ml], and abnormal rates of hsCRP (0 vs.13.33%) and CysC (0 vs.11.67%) in ACS group, P<0.01 all.Conclusion: Serum hsCRP and CysC level measurements can effectively predict and assess occurrence, development and prognosis of disease in ACS patients, and provide clinical valid evidence for its diagnosis, prevention and treatment.

OBJECTIVE To investigate the distribution and the resistance rate of Shigella in Anhui Province to guide the choice of antibacterials. METHODS Ninety one strains of Shigella were cultured in Sep 2005.The groups were identified by biochemical and serologic tests.Susceptibility of 91 strains of Shigella in Anhui to various antibiotics was tested using standardized custom dilution MIC panels according to CLSI(2005) guidelines. RESULTS There were 57 strains of Shigella flexneri,31 strains of S.sonnei and 2 strains ofS.boydii among 91 strains of Shigella.The resistance rates of Shigella to cefoperazone/sulbactam and piperacillin/tazobactam were remarkably lower than to other third generation cephalosporins.The susceptible rates to carbopenems were 100%.The resistance rates to ciprofloxacin lactate and pazufloxacin mesilate were 27.47% and 32.97%,respectively. CONCLUSIONS There is a certain resistance rate of the Shigella to fluoroquinolones and the third generation cephalosporins.More attention should be paid to the surveillance and control of such resistance.

Objectives This study was conducted to detect and analyze the presence of plasmidmediated quinolone resistance (PMQR) determinants [qnr,aac-(6′)-Ib-cr and qepA] among clinical isolates of Citrobacter freundii strains isolated from patients in Anhui,China,and to understand the susceptibility of PMQR positive strains to commonly used antimicrobial agents.Methods During the year 2009,31 Citrobacter strains were collected from the First Affiliated Hospital of Anhui Medical University.Polymerase chain reaction (PCR) was used to detect PMQR genes.Amplicons were purified,sequenced and compared with data from the GenBank.Conjugation experiments were conducted to determine whether the qnr-carrying plasmids were self-transferable.The susceptibility of the positive isolates and transconjugants were tested by agar dilution method according to Clinical and Laboratory Standards Institute (CLSI) guidelines.The minimum inhibitory concentrations (MIC) of ciprofloxacin and levofloxacin were determined by E-test strips.Results Among the 31 Citrobacter strains,the qnr genes were detected in 8 isolates (25.8％),among which,6 carried qnrB.Aac-(6′)-Ib-cr and qepA were not identified in these isolates.The qnr genes were transferred from four clinical isolates to their transconjugants.Sequence analysis identified one novel qnrB variant (qnrB24).The resistant rate of qnr-positive clinical isolates to quinolone was 87.5 ％.Most of them were also resistant to various other antibiotics,including cefotaxime (75.0 ％),amikacin (7.5 ％),ceftazidime (62.5 ％),cefapime (37.5 ％),and gentamycin (87.5 ％).All qnr positive strains were susceptible to imipenem.MIC of all transconjugants showed reduced susceptibility to fluoroquinolones,with MIC increased by 10-23 folds.Conclusions Our study shows that qnr gene has occurred in Citrobacter freundii isolates from Anhui Province,China.QnrB is most prevalent in these isolates.Most qnr positive isolates are resistant to commonly used antimicrobial agents.

Objective To provide a reference for local best practice information sheet by way of analyzing the status quo of adult peripheral venous catheters nursing and maintenance.Methods Systematically analyzing the related 487 documents met the inclusion criteria in CBMdisc,CNKI Database and WanFang Database from the year of 1990 to 2013 by biliometric analysis methods.Results The number of documents,rising year after year,stood mainly in nursing journals,of which the majority authors are from Guangdong [10.3％(50/487)],Anhui [9.0％(44/487)] and Hubei [7.6％(37/487)].50.3％ (245/487)of the documents did not refer in particular to the object.The three major research concerns are the prevention and treatment of complications[80.9％(394/487)],cannulation [23.6％(115/487)] and maintenance [19.9％ (97/487)].Conclusions Peripheral venous catheter cannulation and maintenance has gained widespread attention among the domestic clinical staffs,but the overall quality of articles concerning these aspects is not high.High-quality research papers are expected to provide better evidence for local best practice information sheet.

Objective To explore the effect of insulin subcutaneous pump combined with psychological intervention on gestational diabetes mellitus.Methods A total of 118 patients were enrolled in this study from November 2015 to October 2016 in Lishui central hospital.The patients were randomly divided into the experimental group and the control group according to the time of hospitalization.The experimental group was given insulin subcutaneous pump combined with psychological intervention.The control group was given insulin subcutaneous pump.Results After intervention, the degree of complete compliance in the experimental group was 86.44% and 28.81% before intervention, the difference was statistically significant(P<0.05).Compared with before treatment, blood glucose and glycosylated hemoglobin were decreased after treatment(P<0.05).The incidence of complications in the two groups include: pregnant women with excessive amniotic, neonatal hypoglycemia, pregnancy induced hypertension syndrome and so on.The difference of complication rate between the two groups was statistically significant(P<0.05).Conclusion The timely and accurate psychological guidance of pregnant women with diabetes mellitus can control the blood glucose in the normal range, reduce the occurrence and development of maternal and child complications, and ensure the safe and healthy mother and child health.

Objective To detect the integration of hepatitis B virus (HBV) DNA in HBVrelated human hepatocellular carcinomas (HCC). Methods Extracted DNA from the liver tissue samples and amplified by nested polymerase chain reaction (PCR) with specially designed U-base primers. According to the known genes and human Alu repeat sequences (Alu repeat) , primers were designed respectively. Integrated clones combined target HBV DNA and the adjacent cell gene sequences were established by PCR and products were sequenced by biotechnology companies.Accurate locations of HBV genes integrated in the human genomes were analyzed by national center for biotechnology information (NCBI) basic local alignment search tool (BLAST) and Map Viewer search. Results In 24 HBsAg positive HCC samples, 15 cases showed the integrations of HBV fragment. And the other 8 samples didn't show any evidence of integration. Among 14 samples with integration, forward insertions of HBV DNA into the host chromosomal DNA were found in 10 samples and reverse insertions were found in 8 samples while both forward and reverse insertions were found in 5 samples. Analysis from viral-cellular junctions suggested that the integrations were all happened with truncated viral DNA and could be in any locus of X gene. Conclusion HBV DNA integration is not distributed evenly throughout the host genome.

Objective To observe and assess the effect of different dosages of aspirin on inflammatory biomarkers, hemorheology (platelet aggregation rate) and clinical prognosis in patients with acute coronary syndrome ( ACS). Methods ACS patients were randomly assigned to receive different dosages of aspirin treatment orally. Patients in group A,B and C took 100 mg, 500 mg and 1000 mg of aspirin per day respectively. They were treated and followed-up for 1 year. High-sensitivity C-reactive protein ( hsCRP) , IL-6, tumor necrosis TNFot and platelet aggregation rate were examined and major adverse cardiac events( MACE) were recorded. Results A total of 312 patients with ACS were enrolled in the study. The baseline characteristics of the three groups were not different with respect to age, gender, cardiovascular risk profile, level of inflammatory biomarkers and concomitant treatment before and after randomization. The levels of baseline serum hsCRP, IL-6 and TNFa were higher in subjects of the study as compared with normal reference value (P<0. 05, <0. 05, <0. 01) and they decreased significantly after therapy with 3 different doses of aspirin (detected at 30 days, 6 months and 12 months, P <0. 001 ) , but there were no significant differences among the three groups( P >0. 05) . Rehospitalization , MACE and the change of platelet aggregation ratio were not significantly different among the three groups. The incidence of gastrointestinal complaints was significantly higher in groups B and C than in group A ( P < 0. 05 ). Conclusions The levels of serum inflammatory biomarker increase in patients with ACS. Aspirin therapy may decrease the level of inflammatory markers significantly, but increasing the dosage of aspirin from 100 mg to 1000 mg daily does not decrease the level of inflammatory markers and the clinical MACEs further. However, the incidence of gastrointestinal complaints increase significantly with the increase of aspirin dosage.

Objective To study the roles of abnormal expressions of Caspase-8 and protein kinase C(PKC)-β of cardiomyocytes in the development of the apoptosis of cardiomyocyte in diabetic rat. Methods Rats were divided into 4 groups:(1)normal control (NC, n=37),(2)rats given STZ injection and normal diet(STZ,n= 42), (3) rats fed with high fat and high sngar ( HFS, n= 37), (4)rats given STZ injection and high fat and high sugar diet (type 2 DM, n=64). Plasma glucose, insulin and lipids were detected. At the end of experiment, the animals were sacrificed, and their hearts were examined. Pathological changes were observed and the expressions of Caspase-8, PKC-β mRNA were determined by real time-PCR method; apoptosis was analyzed by flow cytometry. Results (1)The body weight was higher in HFS group than in other three groups, and progressively decreased in type 2 diabetes group. The glucose level was highest in diabetic group, and was similar between groups of HFS and NC. (2)The apoptosis showed tendency to ascend during course of disease in diabetes model group. (3)The expressions of Caspase-8 and PKC-β mRNA were significantly enhanced in diabetes model group than in normal control group, and had a tendency to ascend during the course of disease.(4)The myocardial cells of the diabetic rats were rarified and swelling, fibrosis was observed. (5)At the 16th week, the level of plasma glucose was correlated positively with the expressions of Caspase-8 and PKC-β mRNA. Conclusions The enhancement of expressions of Caspase-8 amd PKC-β may play iportat rols in the pathogenesis of diabetic cardiomyopathy,in which apoptosis of the cardiomyocytes increased.

Objective To study the dynamic changes of injury and apoptosis of liver induced by lipid metabolic disturbance in the rats with diabetes mellitus and their correlation with the expressions of sterol regulatory element binding protein-1c(SREBP-1c)and c-Jun N-terminal kinase(JNK).Methods Experimental animals were randomly divided into 4 groups:diabetesgroup(n=64)induced by high-carbohydrate and high-fat diet plus intra-peritoneal streptozeotocin(STZ)injection,normal control(n=37)fed regular diet and receiving citric buffer solution injection,STZ group(n=42)fed regular diet and receiving STZ injection,high gluaxeard fat group(n =37)receiving citric buffer solution injection.Body weight,liver weight,fasting plasma glucose(FPG),fasting insulin(FINS),triglyceride(TG),total cholesterole(TC),alanine transaminase(ALT),asparate transaminase(AST)were detected at various time intervals.The changes of liver histopathology and ultrastructure were observed by ES and Sudan Ⅲ stanings,transmission electrom microscope.The expressions of SREBP-1c and JNK mRNAs and proteins were determined by real time-PCR methods.Apoptosis was analyzed by flow cytometry.Results The diabetic rats showed much lower body weight(P＜0.05)and higher liver weight than controls,STZ group and high-carbohydrate and fat group(P＜0.05),while showed higher levels(P＜0.05)of serum FPG,FINS,TG,TC,ALT,AST.Diabetic rats exhibited fatty degeneration of liver cells accompanied by inflammatory infiltration and fibrosis.Organelle structures were more disturbed and apoptosis was more obviou along with longer course of disease.The expressions of SREBP-1c,JNK proteins and mRNA were significantly enhanced.The rats fed high-carbohydrate and fat diet also showed similar liver lesions and enhanced SREBP-1c,J NK proteins and mRNA expressions but not as severe as in diabetes group Conclusions Insulin resistance and high blood glucose may induce diabetic hepatopathy.The high expressions of JNK and SREBP-1c may play important roles in liver lipid metabolism disorders and cell apoptosis.

Objective To study the development of cardiomyopathy complicated with type 2 diabetes mellitus in the rats. Methods The 120 health male Sprague-Dawley rats, weighing 180-220 g, were divided into 4 groups: (1)STZ-modeled diabetes, fed with high-carbohydrate plus high-fat diet (n=40);(2)fed with regular diet (n=30);(3)and (4)SD rats with citrate buffer instead of STZ injection, fed with high-carbohydrate and high fat diet (n= 25);and fed with regular diet (n= 25); At the 4th, 8 th, 12 th and 16 th week after the intra-peritoneal injection of STZ solution or citrate buffer solution, rats from each group were scarified and examined. Results There were no significant differences in body mass and blood glucose among those groups after one week of feeding (P＞0. 05).After 4 weeks of feeding before injection, the body mass, fasting insulin (FINS) and insulin sensitive index (ISI) were obviously increased in diabetes group and high-carbohydrate plus high-fat control group as compared with STZ control group and normal control group (P＜ 0. 05). There were no significant differences between diabetes group and high-carbohydrate plus high-fat control group,between STZ control group and normal control group (P＞0. 05). After injection, the blood glucose,body mass, ventricular mass, TG and TC were higher in diabetes group and high-carbohydrate plus high-lipid control group than in STZ control group and normal control group (P＜0.05). The above parameters were much higher in diabetes group than in high-carbohydrate plus high-lipid control group, but there was no difference between STZ control group and normal control group (P＜0. 05).Pathological examination showed that the weight of the heart was significantly increased, the myocardial cells were hypertrophied accompanying degenerative changes and apoptosis, the interstitial collagen fibers were hyperplasia in the diabetic rats. The ultrastructures also presented severe damage.These changes indicated that cardiomyopathy was induced in the diabetes rats. Although similar changes were found in the rats fed with high-carbohydrate plus high-fat diet, they were much less significant than those in the diabetic rats. Conclusions Cardiomyopathy developes frequently in the rats with type 2 diabetes mellitus induced by feeding high-carbohydrate plus high-lipid diet and single intra-peritonial injection of 30 mg/kg STZ solution.
