OBJECTIVE To analyze the distribution,risk factors and preventive measures of nosocomial infection in patients with hemodialysis. METHODS Clinical data of 112 patients with hemodialysis were retrospectively reviewed.Statistic analysis was made on relation between the occurrence of nosocomial infection and patients′ age,adequacy of dialysis,dialysis duration,anemia,heart function,serum albumin,catheterization and reused dialyzer. RESULTS 67 infection cases were found.The main infection sites were blood vessel access,respiratory tract,and urinary tract.The infection rates increased significantly in the groups of age 60,inadequate dialysis,dialysis duration more than 1 year,serum albumin,heart failure and hypoalbuminemia compared with the correspondent controly group(P 0.05). CONCLUSIONS Patients with hemodialysis have higher infection rates,the main risk factors are old age,inadequate dialysis,long dialysis duration,severe anemia,heart failure,catheterization and hypoalbuminemia.Therefore the effective measures to reduce the nosocomial infection are strictly aseptic technology,adequate dialyzsis,reducing the invasive operation,ameliorating anemia and improving the nutrition.

Objective To investigate the mechanism of inhibitor of calpain on hyperglycemia-induced apoptosis in cultured rat cardiomyocyte.Methods Cardiomyocytes were randomly divided into three groups (control,high glucose,and ALLN).MTT assay was used to detect the viability of cultured cardiomyocytes.Laser confocal microscopy was used to observe the mitochondrial permeable transition and membrane potential.The change of Caspase-3 activity in cardiomyocytes was detected by western blot.Results MTT assay showed that,after 72 h of hyperglycemia,the viability of cardiomyocytes was significantly declined (55％ ± 11％),and the viability in the ALLN pretreatment group was (70％ ± 15％) (P ＜0.05).After hyperglycemia,the mitochondrial permeable transition of cardiomyocyte was increased (30％ ± 15％ vs 60％ ± 11％,P ＜0.05),and membrane potential was declined.Hyperglycemia could increase the expression of cleaved capsase-3,while with pretreatment of ALLN the expression of cleaved caspase-3 was downregulation(0.42 ± 0.11 vs 0.21 ±0.12,P ＜0.05).Conclusions The calpain inhibitor can protect cardiomyocytes from apoptosis under the high glucose condition.

Irritable bowel syndrome(IBS)is one of the most common functional gastrointestinal disorders,which severely affects the life quality of patients. Currently,the pathogenesis of IBS has not yet been clarified. Visceral hypersensitivity and central algesia abnormality may be involved in the pathogenesis of IBS. Antidepressants can improve abdominal pain,abdominal discomfort,mental disorders and abnormal defecation and enhance the quality of life. This article reviewed the advances in study on antidepressants in treatment of IBS.

Objective To investigate whether stem cell factor(SCF)was responsible for the diabetesassociated depletion of interstitial cells of Cajal in colon(ICC)in diabetic mice.Methods Forty male C57/BL6 mice were randomly divided into the control group(n=10),the diabetic group(n=10),the normal group with immunoneutralization of endogenous SCF(n=10)and the diabetic group with exogenous SCF (n=10).All mice were sacrificed 6 weeks after modeling.The ICC in the proximal colon tissues were investigated by flow cytometry,transmission electron microscopy and Western blot.The SCF in colon tissues and serum were analyzed by Western blot and ELISA.Results The SCF in the serum and proximal colon muscle was significantly reduced in diabetic group compared with the control group(P＜0.05).The changes were accompanied with the depletion of ICC and the uhrastructure damage of ICC.The expression of SCF was significantly decreased in the serum and proximal colon tissues in the normal group after immunoneutralization of SCF.Meanwhile,the depletion of ICC and the ultrastructure damage of ICC was similar to the diabetic group.The expression of SCF in the serum and proximal colon tissues of the diabetic group with exogenous SCF was significantly increased,and which was along with the quantity of ICC and the ultrastructure improved dramatically compared with the diabetic group.Conclusions The decrease of SCF in the serum and colon of the diabetic mice may be responsible for the diabetes-associated depletion of ICC in colon.Exogenous SCF may improve the ICC lesions in diabetic gastroimestinal tract.

ObjectiveTo investigate the influence of gender and psychosocial parameters on the quality of life in patients with irritable bowel syndrome(IBS). MethodsOut-patients from Jan to Oct 2008 in the Department of Gastroenterology at the First Affiliated Hospital of Nanjing Medical University were enrolled. Based on Rome teria IBS was diagnosed. Interviewed by a GI physician with questionnaire of demographic data,Zung self-rating anxiety and depression scale(SAS/SDS) and IBS-specific quality of life(IBS-QOL) questionnaire. Results452 patients were diagnosed as IBS according to Rome Ⅲ criteria. IBS was more common in female. In male, anxiety and depression scales were significantly increased( t =7. 191、6. 459 ,P ＜ 0. 01 ) and the scale of IBS-QOL was significantly decreased ( t =9.119, P ＜ 0.01 ) in female IBS patients. In IBS patients, IBS-QOL scales were negatively associated with the anxiety and depression scales(P ＜0. 01 ). ConclusionThese results suggest that there were gender differences in psychological status and quality of life in IBS patients,and difference psychological status based on gender should influence the quality of life of patients with IBS.

Objective To investigate the role and mechanism of simvastatin on colonic fibrosis in rats with 2,4,6-trinitrobenzene sulphonic acid (TNBS) induced colitis.Methods Forty-eight healthy male Sprague-Dawley rats were evenly divided into six groups:control group,TNBS group,simvastatin treated group Ⅰ,group Ⅱ (from zero to 21 days after modeling,simvastatin 5 mg/kg or simvastatin 20 mg/kg treated),group Ⅲ and group Ⅳ (from seven to 21 days after modeling,simvastatin 5 mg/kg or 20 mg/kg treated).Body weight and disease activity index (DAI) of the rats were inspected,and general colon,histological injury and fibrosis were scored.The expressions of collagen types Ⅰ and connective tissue growth factor (CTGF) at mRNA level were detected by reverse transcription-polymerase chain reaction (RT-PCR).The expressions of collagen types Ⅰ,CTGF and phosphorylation of myosin phosphatase target subunit-1 (p-MYPT-1) at protein level were determined by Western blotting.The data were analyzed by one-way ANOVA.Results Compared with control group,the colon length shortened,while colon weight,DAI score,general colon score,histological injury and fibrosis score significantly increased in TNBS group.And the expressions of collagen types Ⅰ also obviously increased.After intervention of simvastatin,both the colon length and weight of rats were improved.The DAI score,general score,histological injury and fibrosis score were lower than those of TNBS group.The expressions of collagen types Ⅰ,CTGF and p-MYPT-1 (group Ⅰ:0.68±0.22 ; group Ⅱ:0.59 ± 0.27 ; group Ⅲ:0.71 ± 0.20 ; group Ⅳ:0.59± 0.25) in colonic tissue were all lower than those of TNBS group (F=5.169,P＜0.05).There were no statistical significance among four groups (al1 P＞0.05).Conclusion Simvastatin can effectively prevent TNBS-induced rat colitis from colonic fibrosis,the mechanism may be related with Rho-kinase inhibition and down-regulation of CTGF over-expression.
