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.

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 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.

Objective To investigate the profile and antibiotic resistance of bacteria in patients with ascites infection in intensive care unit (ICU) patients in order to provide a reference for rational clinical use of antibiotics. Methods A retrospective analysis was conducted. The bacteria isolated from ascetic fluid patients admitted from January 1st, 2004 to October 31st, 2015 to ICU of the First Affiliated Hospital of Anhui Medical University were identified, and their susceptibility to antibiotics was analyzed. Patients, who were admitted from January 1st, 2004 to December 31st, 2009 were assigned to group A, and patients admitted afterwards were assigned to group B. Results A total of 637 specimens of ascetic fluid were examined, with 185 positive culture (29.0%) during the 12 years, and 203 strains of bacteria were found. Among them 126 strains (62.1%) of gram-negative bacteria (G-), 54 (26.6%) of gram-positive bacteria (G+) and 23 (11.3%) strains of fungi were found. Compared the result of group B with that of group A, the proportion of G- bacteria was increased [71.2% (99/139) vs. 44.2% (27/64)], and that of G+ decreased [17.3% (24/139) vs. 46.9% (30/64)] in group B. The difference was statistically significant (χ2 = 20.34, P = 0.001). The main pathogenic bacteria were G-, and Enterobacteriaceae was the most common pathogenic bacteria in intra-abdominal infection of ICU patients. The isolation rate of Escherichia coli and Klebsiella pneumoniae(35.7%, 10.3%) ranked in the first and third in G- bacteria, respectively. The resistant rate of Escherichia coli against penicillin and third generation cephalosporin were > 95.0% and > 73.3%, and it showed a sensitive rate of 70% to β-lactam/inhibitor, amikacin and minocycline, and a higher sensitivity to carbapenems and tigecycline (11.1%, 0). Forty-eight strains of non-fermentation bacteria were found with a rate of 23.7%. The positive rates of Acinetobacter baumannii in groups A and B were 7.8% (5/64) and 23.7% (33/139), respectively, and they ranked first among non-fermentation bacteria. Twenty strains (62.5%) multidrug-resistant Acinetobacter baumannii were found. Acinetobacter baumannii showed a resistance rate of 84.6% to cefoperazone/sulbactam, 35.3% to minocycline, and 53.3% to tigecycline. Candida albicans was the most commonly isolated fungus in intra-abdominal infections (87.5%). No strains resistant to common antifungal drugs were isolated. Conclusions G- bacteria was the main pathogen in intra-abdominal infection in patients with ascites. Non-fermenters showed an increasing trend of producing infection, and the proportion of multidrug-resistant Acinetobacter baumannii infection increased year by year, and more attention should be taken by attending doctors.

Objective To evaluate previous gastroscopy before percutaneous coronary intervention (PCI) for the risks and benefits of concomitant use of proton pump inhibitors (PPIs) after PCI in patients with non-acute coronary syndrome (non-ACS).Methods The data of 673 non-ACS patients who underwent PCI with stenting were retrospectively analyzed.They were divided into concomitant use of PPIs group and non-PPIs group,then subdivided into high-,moderate-and low-risk groups according to risk factors associated with adverse upper gastrointestinal (GI) events.The incidences of adverse cardiovascular events and adverse upper GI events were compared among groups.Findings of previous gastroscopy were also included.Results Only 82 patients (12.2％) underwent gastroscopy within 5 years before PCI,of whom,27 (32.9％) were diagnosed as having peptic ulcer,and 55.6％ (15/27) of whom were in concomitant use of PPIs.Compared with the non-PPIs group,the rate of adverse cardiovascular events in the concomitant use of PPIs group was significantly higher (22.6％ vs.8.9％,P ＜0.01),and the highest rate (41.7％) was in the high-risk group.However,the corresponding rate of adverse upper GI events was the lowest (4.2％).In the moderate-risk group,90.5 ％ (344/380) of patients were older than 65 years with concomitant use of NSAIDs.The rate of gastroscopy within 5 years before PCI in these patients was remarkably lower than that in patients who had the history of upper GI disease with concomitant use of NSAIDs (concomitant use of PPIs group 14.1％ vs.54.5％ ; non-PPIs group 7.5％ vs.28.0％ ; P ＜ 0.01).In the concomitant use of PPIs group,the rate of adverse cardiovascular events in the former was notably higher than that in the latter (20.5％ vs.9.1％,P ＜0.01),but the rate of adverse upper GI events within 1 year after PCI were similar (9.0％ vs.9.1％).Conclusion Previous gastroscopy before PCI could provide the baseline information of upper GI disease,which may be helpful for the evaluation of concomitant use of PPIs after PCI so as to decrease the incidence of adverse cardiovascular events.Special attention should be paid to those patients older than 65 years in the moderate-risk group and concomitant use of NSAIDs.

Objective To investigate the difference between Asia-Pacific Colorectal Screening (APCS) scoring system and colorectal cancer sequential screening criteria issued by the Health Ministry of China (China sequential criteria) in the evaluation of high-risk colorectal neoplasm in patients undergoing coronary artery angiography (CAG) examination.Methods The data of 870 patients aged from 40 to 74 who underwent CAG examination were retrospectively analyzed.The measurement data were analyzed by t test and the count data were aralyzed by x2 test.Results There were 72 patients aged from 40 to 49 years old.Among them,eight patients were stratified as high-risk population according to the Chinese sequential criteria; however there was no high-risk population by APCS.There were 798 patients aged from 50 to 74 years old.There were 460 patients stratified as high-risk population by APCS.The percentage of CAG negative group (34.7％) was significantly lower than that of the coronary artery disease (CAD) group (68.0％,x2 =77.74,P＜0.01).According to the Chinese sequential criteria,and there were 134 patients stratified as high-risk population,and there was no significant difference between the CAG negative group (17.7 ％) and the CAD group (16.4％,P＞0.05).Among the patients aged from 50 to 74 years old without family history of colorectal cancer in first-degree relatives,72 cases (29.0％) of the CAG negative group and 316 cases (57.5％) of the CAD group were stratified as high-risk according to APCS,however not stratified as high-risk by the Chinese sequential criteria.About 90.5 ％ (351/388) of them were male smokers.According to APCS,30 cases (12.1％) of the CAG negative group and 32 cases (5.8％) of the CAD group were stratified as middle-risk population,however stratified as high-risk population by the Chinese sequential criteria.About 75.8％ (47/62) of them were female non-smokers.Conclusions The percentage of patients stratified as high-risk population by APCS was higher than that by the Chinese sequential criteria.In patients aged from over 50 to 74 years old and without family history of colorectal cancer in first-degree relative,APCS maybe overestimated the risk degree of colorectal neoplasm in male smokers and underestimated the risk degree in female non-smokers.

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.

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.
