Objective To investigate the protection effects of teprenone in aspirin-induced gastric mucosa injury.Methods From 2008 to 2010,a total of 296 patients who took aspirin for the first time at the Department of Cardiovascular,First Hospital Affiliated to Zhejiang Chinese Medicine University were randomly divided into two groups.There were 166 cases in aspirin group,which took aspirin 100mg daily; 130 cases in aspirin and teprenone group,the aspirin dose equivalent with aspirin group and took teprenone 50mg/time,3 times/day orally.Gastrointestinal symptoms and gastric mucosa injury of patients in these two group were inspected at 3 month,6 month and 1 year.Results A total of 143 cases were recruited in aspirin group and 118 cases in aspirin and teprenone group.After taking medicine for 3 months,the occurrence rate of gastrointestinal symptoms in aspirin group was 1.40 ％.Compared with aspirin and teprenone group,the difference was statistical significant (0,x2 =1.663,P＝ 0.197).Follow up after taking medicine for 6 months,the occurrence rate of gastrointestinal symptoms in aspirin group was 4.96％.Compared with aspirin and teprenone group,the difference was statistical significant (0,x2 ＝6.021,P＝0.014).Follow up after taking medicine for 1 year,the occurrence rate of gastrointestinal symptoms in aspirin group was 20.15 ％.Compared with aspirin and teprenone group,the difference was statistical significant (1.69％,x2 =20.984,P=0.001).Compared with aspirin group,the symptom and endoscopy score of aspirin and teprenone group decreased significantly at follow-up for 6 months and 1 year (P＜0.05; P＜0.01 ).Compared with at 6 month,the symptom and endoscopy score of aspirin group at 1 year increased significantly (P＜0.05 ; P＜0.01).Conclusion Teprenone has certain protection effects in aspirin-induced gastric mucosa injury.Long-term use of conventional doses of aspirin may cause vary degrees of gastric mucosal injury,and the gastric mucosal injury get more severe as the time of taking medicine increases.

The clinical internship is an important transitional period for humanistic spirit cultivation of the medical students.But in this period there are some problems exposed.For example,there is the lack of transitional link in management; the clinical instruction doctors lack educational consciousness or guidance ability,the medical students pay little attention to enhancing the individual humanistic spirit level and there is a gap between theory and practice of humanistic spirit for them.Strengthening training for students,attaching importance to training,selection and incentive of clinical instruction doctors and revising handbook of clinical internship will help to solve the problems.

Objective To study the status of prevalence of hyperlipidaemia among rural residents aged from 30 to 59 in Changzhou and provide evidence for taking prevention measures.Methods By the means of the cluster random sampling,a questionnaire survey and medical examination were conducted among 10 018 permanent residents in rural areas of Changzhou.The fasting plasma cholesterin(TC),triglycerides(TG),high density lipoprotein-C(HDL-C) were measured.Age-standardized prevalence rates were calculated by using the direct standardization method according to 2000 China population census.Results The prevalence of hyperlipidaemia of this population was 32.3%,the age-standardized prevalence was 31.3%,and the prevalence among men was significantly higher than women(P

OBJECTIVE To re-evaluate Bifidobacterium from microecological point of view. METHODS With the development of microecology,it is paid more and more attention to the medical field.The genesis and development of diseases were closely related with microbe imbalance.As a kind of common microbial population in intestinal tract,Bifidobacterium are one of the most important sources for the exploitation of microecological preparation.Bifidobacterium were re-evaluated by the reference review method. RESULTS This review is focused on the current situation,bioactivity,clinical application,and prospective of Bifidobacterium. CONCLUSIONS Bifidobacterium have good application prospects.

A fast,simple and sensitive high performance liquid chromatographic (HPLC) method has been developed for determination of 10α-methoxy-6-methyl ergoline-8β-methanol (MDL,a main metabolite of nicergoline) in human plasma.One-step liquid-liquid extraction (LLE) with diethyl ether was employed as the sample preparation method.Tizanidine hydrochloride was selected as the internal standard (IS).Analysis was carried out on a Diamonsil ODS column (150 mm × 4.6 mm,5 μm) using acetonitrile-ammonium acetate (0.1 mol/L) (15/85,v/v) as mobile phase at detection wavelength of 224 nm.The calibration curves were linear over the range of 2.288-73.2 ng/mL with a lower limit of quantitation (LLOQ) of 2.288 ng/mL.The intra- and inter-day precision values were below 13％ and the recoveries were from 74.47％ to 83.20％ at three qtality control levels.The method herein described was successfully applied in a randomized crossover bioequivalence study of two different nicergoline preparations after administration of 30 mg in 20 healthy volunteers.

Objective To investigate the roles of microRNA-382 (miR-382) in the pathogenesis of renal tubulointerstitial fibrosis (TIF).Methods Human kidney epithelial cells (HK2)transfected with miR-382 inhibitor (antagomiR-382) were used to examine the effect of miR-382 abundance on cell polarity,as well as to test the complementary relationship between miR-382 and its predicted target gene heat shock protein 60 (HSPD1),which was further verified by 3'-untranslated region luciferase assay and site-directed mutagenesis.The role of miR-382 played in the development of renal interstitial fibrosis and redox regulation was examined in a mouse unilateral ureteral obstruction (UUO) model.Locked nucleic acid (LAN)-modified anti-miR-382 was intravenous delivered via tail vein 30 min prior to UUO,and repeated the dosage 24 h after the surgery.For clinical verification,renal biopsy specimens from 12 IgA nephropathy (IgAN) patients were collected,6 patients with moderate to severe TIF and 6 patients without TIF.The relative abundance of miR-382 and HSPD1 protein was analyzed by using in situ hybridization and immunohistochemistry.Results HSPD1 was confirmed to be a new,direct target gene of miR-382 by in vitro 3'-untranslated region luciferase assay and sitedirected mutagenesis.The development of epithelial transition in HK2 cells was accompanied with upregulation of miR-382 [(6.54±0.96) vs (1.12±0.26),P ＜ 0.05].Blocking the expression of miR-382 could reversed the progression of epithelial transition partially.In UUO mice the abundance of miR-382 was up-regulated [(6.89 ± 2.47) vs (1.00±0.42),P ＜ 0.01] while HSPD1 and Trx were downregulated compared with the sham group.Down-regulation of miR-382 was associated with significant decrease in TIF,but increase in HSPD1 and thioredoxin protein compared with UUO group [HSPD1:(0.34±0.10) vs (0.14±0.05);Trx:(0.79±0.18) vs (0.36±0.16);all P ＜ 0.05].The expression of miR-382 was up-regulated and HSPD1 was significantly down-regulated in IgAN patients with TIF.Conclusions miR-382 play an important role in renal tubulointerstitial fibrosis in human and mice.HSPD1 is one of the target genes of miR-382.The down-regulation of HSPD1 and the decrease ability of anti-oxidative stress may be the important mechanism of miR-382 involved in renal tubulointerstitial fibrosis.
