DREEM inventory developed by Dundee University in England was used to measure medical education environment of Medical University of China. It was found that the total perception of educational environment and the perception of teachers and learning of female students were higher than those of male students, but female students' confidence was lower than male students'. In this article the authors will express their own opinions on these problems and propose appropriate countermeasures.

The management of frailty in elderly patients with chronic kidney disease (CKD) has been receiving increasing attention.Frailty in elderly patients with CKD has a high incidence and is used for risk prediction of adverse outcomes,including death,hospitalization,falls,dialysis and so on.A range of pathophysiological changes caused by CKD,aging and multimorbidity work together to promote the development of frailty.Treatment for CKD patients with frailty includes mainly nutritional support,exercise,drug therapy and comprehensive intervention.This article reviews recent research progress concerning frailty in elderly CKD patients.

Disability insurance is one of main component of isurance. This paper made comparison of disability standard of insurance among some countries and regions and drawn serveal chracteristics. With the review of Chinese Disability Standard for Insurance (1998 version),implications and strategies had been proposed for further revision.

Recent reports have indicated that Statins could remarkably improve the prognosis of patients suffered from coronary artery disease.And this effect is not only due to Statin's lipid-regulating function,but also correlated to its non-lipid-regulating action.Atorvastatin is the latest kind of statins.In this article,we specified the non-lipid-regulating effect of Atorvastatin in the prevention and therapy to coronary artery disease.Furthermore,we summarized its corresponding clinical evaluation or security.

AIM:To compare the efficacy of three types of eye care (artificial tear, moist chamber and polyethylene covers) for preventing exposure keratopathy in intensive care patients.METHODS: Intensive Care Unit (ICU) patients were randomly divided to three treatment groups, including artificial tear group(29 cases), moist chamber group (27 cases) and polyethylene covers group (28 cases). Patients in artificial tear group received two drops of carboxymethylcellulose dropped to each eye every 2 hours. The moist chamber and polyethylene covers groups were changed every 12 hours or as needed if they became unclean or torn. Corneal fluorescein stain was performed daily.RESULTS:No one in the polyethylene covers group and one case(4%) in the moist chamber group had exposure keratopathy compared to 8 cases (28%) in the artificial tear group. There were statistical significance differences between both artificial tear group and moist chamber group (P=0.02), artificial tear group and polyethylene covers group (P=0.003). Everyday time of eye care in the artificial tear group, the moist chamber group and the polyethylene covers group was respectively 26.69±2.39, 35.33±2.63 and 7.48±0.87 minutes. Everyday time of eye care in the polyethylene covers group was statistically more time-saving than that in the artificial tear group (P<0.01) and the moist chamber group (P<0.01). CONCLUSION: Polyethylene covers are more effective and time-saving in reducing the incidence of corneal damage in intensive care patients.

Objective To study the effect of cellular glutathione (GSH) in relieving the cytotoxicity induced by arsenic on HaCaT. Methods The HaCaT cells were pre-treated with N-acetylcysteine (NAC) and L-buthionine-[S'R]-sulfoximine (BSO) for 24 h, then treated with sodium arsenite (NaAsO2) by adding it into the medium for 24 h. Alarmarblue assay was used to detect the proliferation of the cells. Results The reduction rate of Alarmarblue increased when the HaCaT cells were treated with 0.001-10.000 ?mol/L of NaAsO2 alone (P

Objective To study the directly injury effects of lipopolysaccharide(LPS) on human vascular endothelial cells(HVEC).Methods Lipopolysaccharide with different concentrations added into cultured vascular endothelial cells of human umbilical vein,at different phase after lipopolysaccharide being added,the concentrations of nitric oxide(NO),lactic acid dehydrogenase(LDH) were measured,and the adhesion of HVEC to polymorphonuclear leucocytes(PMN) were observed,the morphological changes of HVEC were detected by phase-contrast microscope.Results The NO content,LDH activity were obviously elevated with increase of LPS concentration(P

Objective:To construct NBS1 microRNA expressing eukaryotic recombinants,and identify biological activity of recombinants in Hela cell after transfection.Methods:According to sequence of NBS1mRNA,the NBS1 pre-microRNA was designed and synthesized,then cloned into the GFP reporter pcDNA6.2-GW/EmGFP-miR vector and transfected into Hela cell line.To detect integrity of inset fragment through colony PCR and sequencing analysis.The biological activity of recombinants through identify interference efficiency of NBS1 microRNA recombinants by way of Real-Time PCR and Western blot were determined.Results:Sequences of inset fragment in four microRNA expressing recombinants were correct.NBS1 mRNA and protein expression of four microRNA recombinants were decrease,which is the lowest in the NBS1mi-2 group.Conclusion:Four NBS1-targeting microRNA expressing recombinants all have biological activity in Hela cell line,and NBS1mi-2 recombinant has the most interference efficiency.The microRNA expressing plasmid which were successfully constructed and lay foundation for the studies on the tumor gene therapy of microrna targeting NBS1.

Objective To improve the level of diagnosis and treatment of the traumatic and hemorrhagic shock.Methods 50 cases of patients with sever traumatic and hemorrhagic shock treated in our department between May 2004 and May 2007 were analyzed retrospectively,and their age,shock severity scale,time to hospital after in- jury,operation,fluid resuscitation volume etc were analyzed to show the relationship between the factors and the out- come.Results The rescue success rate was 76%(38 cases),and traumatic mortality was 24%(12 eases).Conclu- sion Shock severity scale and incorreet resuscitation manipulation are the main factors affecting the result of resusci- tation and treatment of traumatic shock,and early surgery can effectively improve the result of severe trauma thera- py.

Objective To analyze drug resistance data of Enterococcus faecalis and Enterococcus faecium,submitted by member units of Chongqing bacterial drug resistance monitoring network,and to provide the basis for our city effective application of antimicrobial agents and the reference.Methods Target bacteria identification and drug susceptibility test were performed by member units,according to the national technology scheme of bacterial drug resistance monitoring network and the results were determined according to standards published by Clinic and Laboratory Standard Institute(CLSI) in 2015.WHONET5.6 software was used to analyze drug susceptibility,and drug resistance difference was analyzed by using SPSS21.0 software.Results A total of un-repeated 1 811 strains of Enterococcus faecalis and 1 601 strains of Enterococcus faecium,accounting for 13.1% of all positive strains.The resistant rates of the two kinds of bacteria to vancomycin were 0.5% and 1.8%,to rinathiazole amine were 2.5% and 0.5% respectively.Tigecycline resistant strains were not founded.The resistant rate of Enterococcus feaclis to ouinupristin/dalfopristin was 90.1%,to tetracycline was 78.8%,to high concentration of gentamicin was 43.0%,to penicillin,ampicillin and nitrofurantoin was less than 7%.Except ouinupristin/dalfopristin and tetracycline,the resistant rate of Enterococcus faecium to the other drugs were significantly higher than Enterococcus faecalis(P<0.05).Strains isolated from children and adult patients,Intensive Care Unit(ICU) and un-ICU patients were with differences of drug resistance(P<0.05).Conclusion Most of Enterococcus infection could be caused by Enterococcus faecalis and Enterococcus faecium.Monitoring of drug resistance might be helpful for rational and effective usage of antimicrobial agents.
