Objective To explore the relationship between field cognitive style and self-handicapping of medical students.Methods 124 medical students were measured by embedded figure test (EFT) and self-handicapping questionnaire (SHS).Results ①The scores of self-handicapping questionnaire were significantly different in whether they like their major or not(33.61±5.21,35.94±5.16,t=-0.218,P=0.031).Differences were also found in whether they could obtain the scholarships (33.20±6.19,35.12±4.12,t=-0.247,P=0.043),and in whether they were in a relationship(35.35±5.48,33.39±5.01,t=2.063,P=0.041).②Compared with field-independent cognitive style students,Field-dependent cognitive style students ' self-handicapping score was higher (35.69±3.91,32.63±6.08,t=3.303,P=0.001).③Field-dependent cognitive style,dislike their major and be in a relationship were the significant predictors of self-handicapping.Conclusion Correlation exists between field cognitive style and self-handicapping of the medical students.Students who belong to field-dependent cognitive style are more prone to self-handicapping than field-independent cognitive style students.

Aim To study the inhibitory effect of Maoeryan vegetable acid on human SGC-7901 strain cells and the mechamism of it. Methods The inhibitory effects of Maoeryan vegetable acid on human SGC-7901 strain cells were determined by flow cytometry, methods of MTT and trypan-blue.Results Maoeryan vegetable acid at a does of 10.0, 1.0 and 0.1 mg?L -1 was given to human SGC-7901 strain cells for 48 h,respectively, and the inhibitory rate of human SGC-7901 strain cells was 82.9%,42.7% and 24.6%,respectively;cellular growth inhibitory rate was 76.4%,56.9% and 42.6%, respectively;as well as apoptosis rate was 26.8%,22.5% and 15.6%, respectively. Conclusion The Maoeryan vegetable acid has significant inhibitory effect on human SGC-7901 strain cells and the inhibitory effect increases with the increase of concentration and time.

The aim of this study is to investigate the effect of fluoxetine (FLX) on the expressions of BDNF and Bcl-2 in the hippocampus, the amygdala and the prefrontal cortex of conditioned fear (CF) model mice. Forty eight mice were randomly divided into three groups, normal control group, CF stress group and FLX-pretreated CF group. The FLX-pretreated CF group was given FLX (10 mg x kg(-1) x d(-1)) for 7 days before CF stress. After CF stress model was established, all mice were given behavioral experiments to test whether FLX impaired or improved the auditory and contextual fear conditioning. Then mice were sacrificed. The expressions of BDNF and Bcl-2 were detected by Western blotting. The results showed that the freezing time of FLX-pretreated CF group was significantly lower than that of CF group; FLX pretreatment up-regulated the expression of Bcl-2 in the hippocampus at 1 d after CF stress (P < 0.001), but no significant differences was observed at 7 d; BDNF significantly increased in the hippocampus at 7 d (P < 0.001), but no differences at 1 d; the expressions of BDNF and Bcl-2 in the amygdala and the prefrontal cortex were of no obvious differences between CF group and FLX-pretreated CF group at 1 d or 7 d after CF stress. Parallel to these changes, pretreatment with FLX could affect histopathologic changes induced by CF stress. Furthermore, the results indicated that FLX pretreatment could protect against CF stress-induced neurological damage via the activation of BDNF and Bcl-2 in hippocampus.

Objective To evaluate the protecting effects of matrine on chemotherapy related hepatic lesion and its possible mechanism.Methods The positive rate and severity of hepatic lesion were compared between pa- tients being treated with or without matrine during chemotherapy processes.Furthermore,the difference of liver pro- tecting effect of this Chinese medicine between hepatitis B virus(HBV)infection chemotherapy patients and disinfec- tion patients were also analyzed.Results Both the rate of hepatic lesion and level of ALT in matrine treated group were much lower than those in untreated group in chemotherapy patients.The rate of hepatic lesion and level of ALT in HBV infection patients were higher than those in HBV disinfection patients in untreated group,while the signifi- cant difference of these two parameters between HBV infection patients and disinfection patients were disappeared in matrine treated group.Conclusion Matrine has hepatic protecting effect in chemotherapy related liver lesion.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

Objective:To understand the current work situation of clinical pharmacy in medical institutions in Wuhan city .Meth-ods:A questionnaire survey was employed to investigate the stuffing situation of clinical pharmacists , quality of clinical pharmacists and clinical pharmacy development in medical institutions above class II in Wuhan city .The results were analyzed statistically .Re-sults:There was notable difference in the situation of clinical pharmacist among medical institutions above class Ⅱin Wuhan city , and so was in the development of clinical pharmacy .Conclusion:Clinical pharmacy work in medical institutions still demands much atten-tion and support from the relevant departments , and clinical pharmacists own need make great efforts constantly .

Objective To explore the anti-inflammatory effect of erythropoietin (EPO) on hepatic ischemia reperfusion (IR) injury in fatty liver rats.Methods A total of 100 male SD rats were fed with high-fat diet for 12 weeks.After the model was successfully established,the fatty liver rats were randomly divided into sham-operation (SHAM),the ischemia-reperfusion (IR) and EPO preconditioning group.Serum ALT and AST as well as hepatic histopathological changes were measured.Xanthine oxidase method was used to detect the liver tissue SOD.Thiobarbituric acid method was used to detect the MDA.Enzyme-linked immunosorbent adsorption assay (ELISA) was used to detect the plasma tumor necrosis factor alpha (TNFαt) and interleukin 1 (IL-1).Results In the EPO preconditioning groups the swelling hepatocytes was observed,but the inflammatory cell infiltration was significantly decreased and no necrosis of hepatocytes was found.ALT and AST in the EPO preconditioning groups were significantly lower than those in IR group (P ＜ 0.05).The levels of SOD activity in the EPO preconditioning groups were significantly higher,but MDA were significantly lower than that in IR group (P ＜ 0.05).The TNF-α and IL-1 in the EPO preconditioning groups were significantly lower than those in IR group (P ＜0.05).The values of ALT,AST,TNF-α,IL-1 and MDA in the EPO groups were:EPO-1 ＞ EPO-2 ＞ EPO-3 (P ＜ 0.05);but the values of SOD in the EPO groups were:EPO-1 ＜ EPO-2 ＜ EPO-3 (P ＜ 0.05).Conclusions EPO preconditioning has a protective effect against hepatic IR injury in fatty liver rats,possibly through inhibiting the inflammatory reaction to prevent the IR injury.The anti-inflammatory effect of high-dose EPO is better than that of low-dose EPO.
