Objective To study the relation between the effect of Curcumin on the proliferation and activation of hepatic stellate cells(HSC)and the expression of the peroxisome proliferator-activated receptor?(PPAR?).Methods The rat HSC was isolated from SD rats through in situ perfusion of liver with Pronase E and density-gradient centrifugation with Nycodenz.The subcultured cells were treated with corresponding compound.The inhibition effect on HSC proliferation was determined by MTT colorimetry.The total RNA was extracted by TRizol reagent,and the gene expression level of PPAR? and smooth muscle actin (?-SMA)were determined by semi-quantitative RT-PCR.The total cellular proteins were extracted and separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis,and the protein level of ?-SMA was determined by Western blotting.Results The MTT analysis results showed that Curcumin inhibited HSC proliferation between 10 and 50 ?mol/L in a dose-dependent manner.In the Day 1,4,7 of primary HSC and passaged HSC,the expression of PPAR? mRNA decreased with HSC activation extent;Curcumin could up-regulate the expression level of PPAR?.Curcumin suppressed the expression of ?-SMA not only at the gene level but also at the translation level.But all these effects of Curcumin on HSC could be blocked by the PPAR? specific antagonist GW9662.Conclusion The effect of Curcumin on HSC cell proliferation and activation is through the up-regulation of PPAR? signal.

Objective To understand the status of hand hygiene(HH) among patients hospitalized in departments of infectious diseases and their families in Yantai City, and provide reference for HH intervention.Methods Patients and their families(n=221) in departments of infectious diseases of secondary and above levels of hospitals as well as infectious diseases hospitals in Yantai in July-August 2015 were selected for questionnaire survey, education and implementation status of HH were investigated;hand bacteriological sampling was performed on some patients and their families (n=62) to investigate effect of hand-washing.Results 61.99% of patients and their families had received verbal HH education, only 18.55% indicated to have seen health care workers(HCWs) to perform the six step hand-washing method;50.68% of the respondents didn't understand the six step hand-washing method, and 85.52% never performed the six step hand-washing, the main reason is that they didn't know how to perform.93.21% of patients(n=206) and their families believed that hand-washing was important.The cognition of HH opportunities in daily life was relatively higher(61.54%-94.51%),and in hospital environment was relatively lower(36.15%-49.23%),only 36.15% of the families washed hands before left the hospital.Unqualified rate of detection results of sampling of hands of patients with infectious diseases and their families was 83.87%.Conclusion Patients with infectious diseases and their families are deficient in HH knowledge and behavior, medical institutions should carry out systematic and standard HH education to reduce the risk of healthcare-associated infection.

Aim To study the effect of Curcumin on the apoptosis of hepatic stellate cells (HSC), and the correlation between the effect and peroxisome proliferator-activated receptor ?(PPAR?) signal.Methods The HSC was isolated from normal SD rats through in situ perfusion of liver with protease E and density-gradient centrifugation with Nycodenz.The subcultured cells were treated with corresponding compounds. Cell apoptosis was detected by Hoechst 33258 staining. PPAR? subcellular distribution was detected by immunofluorescent staining. Total RNA, total protein and nuclear protein were extracted respectively, target gene and protein levels were determined by semi-quantitative RT-PCR or Western blot.Results There was nearly no apoptosis in activated HSC. Curcumin treatment induced the apoptosis of HSC, enhancing PPAR? nuclear translocation/redistribution.At the transcription and translation level,curcumin upregulated nuclear PPAR? expression, inhibited anti-apoptotic Bcl-2 expression, and promoted pro-apoptotic Bax expression; but all these effects could be reversed by PPAR? antagonist GW9662.Conclusions Curcumin induces HSC apoptosis by enhancing PPAR? expression and nuclear translocation/redistribution.

In order to determine the challenge dose of pigeon paramyxovirus type 1 (PPMV-1) inactivated vaccine (S-1 strain). The virus titer of PPMV-1 E5 allantoic fluid (Chuansha strain) was determined using SPF chicken embryos in this research. After inoculating 30-day-old and 120-day-old pigeons with low-HI antibody against PPMV-1 (HI antibody < or =2) with different doses of PPMV-1 (Chuansha strain), the clinical symptoms and histopathological lesions of the challenged pigeons were examined. The results showed that the minimal lethal dose (MLD) of PPMV-1 (Chuansha strain) was 102.5 ELD50, so we determined that 10(5.5) ELD50, which was 1000 times the MLD, could be taken as the challenge dose in the vaccine efficacy test for PPMV-1 inactivated vaccine (S-1 strain).

OBJECTIVETo investigate the risk factors of vaginal dilators by 567 adverse event reports, and to provide a reference for the reasonable use.

METHODSWith retrospective case study, analyzed 567 reports induced by vaginal dilators by National Adverse Drug Reaction Monitoring Center in 2012.

RESULTSExpected treatment of disease might be relevant with severity of adverse events, while age was not the related factor; the influencing factor of consequences of grading was the classification of the cause of adverse events.

CONCLUSIONMonitoring should be strengthen in order to reduce or avoid the vaginal dilator adverse events.
