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 evaluate the role of total glucosides of peony (TGP) as adjuvant therapy for prevention of cardiac allograft rejection in rats. METHODS: Rats with cardiac allograft were randomly divided into control group, tacrolimus-treated group, TGP-treated group and tacrolimus plus TGP-treated group. Graft survival time was observed. Allografts in some cases were examined by histological study seven days after transplantation. At the same time, the levels of CD4(+) and CD8(+) T cell subsets in peripheral blood were examined by using flow cytometry; the hepatic function and renal function of recipients were also tested. RESULTS: The graft survival time of the tacrolimus-treated group and tacrolimus plus TGP-treated group was (11.14+/-1.57) d and (13.57+/-1.99) d, respectively. The graft survival time of the tacrolimus plus TGP-treated group was longer than that of the tacrolimus-treated group (P<0.05). The histological study showed that the rejection of the tacrolimus plus TGP-treated group was slighter than that of the tacrolimus-treated group. The levels of CD4(+) T cell subset in the peripheral blood of the tacrolimus-treated and tacrolimus plus TGP-treated groups were (38.71+/-5.15)% and (32.43+/-4.39)% respectively 7 days after transplantation. The level of CD4(+) T cell subset in the tacrolimus plus TGP-treated group was lower than that in the tacrolimus-treated group (P<0.05). The level of CD8(+) T cell subset and the hepatic and renal function had no significant differences between the tacrolimus-treated group and the tacrolimus plus TGP-treated group. CONCLUSION: Effects of tacrolimus plus TGP in prevention of rejection are better than tacrolimus monotherapy in rats with cardiac allograft and without increasing side effects.

[Objective]To investagate the anatomic features in the approach to the brachial plexus in neck in order to make the exposure of brachial plexus more convenience and safer.[Method]Neck of six embalmed adult cadavers were made serial sectional specimens,which was observed to identify the border,composition and anatomic relation of fat layer between the superficial and deep layer of cervical fascia in the posterior triangle of neck with the brachial plexus.[Result]There was no branches of superficial cervical plexus in the fat layer between the superficial layer and deep layer of cervical fascia below the middle neck,in which there was no important structures except omohyoid muscle and transverse cervical artery.The deep layer of cervical fascia was dense and was directly superficial to the brachial plexus.[Conclusion]Exposure of brachial plexus in the neck would be more safe and convenience upon the understanding of anatomic relatiowship between cervical fascia and brachial plexus.

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.

Objective:To explore strategies of improving patients' stereotyping of nurses, by analyzing patients′ stereotypes of nurses.Methods:The phenomenological analysis method in qualitative research was used to conduct semi-structured interviews with 12 inpatients by objective sampling method.Results:The patients′ stereotype of nurses could be summarized into three topics, it mainly consisted of three aspects: patients′ cognition of the role of nurses, patients′ stereotype of nurse-patient relationship and factors affecting nurse-patient relationship from patients′ perspective, among which factors affecting nurse-patient relationship included doctors′ attitude towards nurses, public opinion effect of media reports and patients′ negative psychological experience.Conclusions:The prejudice of patients to the relationship between nurses and patients is not optimistic, it is suggested to improve patients′ stereotyping of nurses by reconstructing the ideal role of nurses, building harmonious trusting relationships and providing friendly support from the "others".
