Aim To study the effects of HSP70 on hepatic ischemia-reperfusion injury after heat preconditioning in rats.Method To establish the models of the hepatic ischemia-reperfusion injury. 42 Wistar rats were randomly divided into 6 groups, (each group had 7 rats): normal group(N); quercetin injection group(Q); ischemia-reperfusion group(I); heat preconditioning 16 hours before ischemia-reperfusion group(H+I); quercetin injection before heat preconditioning group(Q+H+I); quercetin injection before ischemia-reperfusion group(Q+I).We detected the activity of serum enzyme of ALT,AST and the pathological changes of the liver;The expressions of HSP70 of the rats were observed by Western blotting. Results The expressions of HSP70 from high to low were:group H+I,group I,group Q+H+I,group Q+I,group Q,group N; The serum levels of ALT and AST from high to low were: group Q+I,group I,group Q+H+I,group H+I,group Q,group N;All groups had visibly hepatic histological changes respectively.Conclusion The protection of heat stress pretreatment from ischemia reperfusion injury was possibly performed by inducing the expression of HSP70.

BACKGROUND: Islet transplantation is an effective method for the treatment of type 1 diabetes mellitus and parts of type 2 diabetes mellitus. However, its application is hindered by insufficient sources and immunologic rejection. Though transdifferentiation of pancreatic stem cells is at the starting step, it is thought to be the hopeful source for islet cell transplantation.OBJECTIVE: To look for a suitable cells-transplantation source for the treatment of diabetes mellitus. METHODS: The pancreatic ductal epithelial cells were separated from Kunming mice and cultured in DMEM/F12 medium supplemented with keratinocyte growth factor, hepatocyte growth factor and nicotinamide, etc. Samples were taken at different time points for light microscopy and electron microscope. The changes of CK-19 and PDX-1 were detected by immunocytochemistry at 1 and 16 days. The expressions of insulin and glucagon gene were detected by RT-PCR at 1 and 16 days. The physiologic function of these islet-like clusters was determined by dithizone staining and glucose stimulation at 21 days. RESULTS AND CONCLUSION: A large number of epitheliod cells were CK-19 immunoreactive positive and few of them were PDX-1 positive at 1 day after isolation, then CK-19 positive cells proliferated quickly and formed substantial plaques of epithelial cells in cobblestone pattern. At 16 days later, these cells begin to form islet-like clusters gradually, while most of them were PDX-1 immunoreactive positive. The analysis of mRNA by RT-PCR showed very low levels of insulin and glucagon mRNA in the starting materials but increase was found as the process of transdifferentiation. At 21 day differentiated islet-like clusters were stained red by dithizone. In those samples exposed to a stimulatory 15 mmol/L glucose, there was a 1.6-fold increase in insulin compared with to 5.6 mmol/L glucose (P < 0.05). Pancreatic ductal cells of adult Kunming mice could proliferate quickly and have the potency of transdifferentiation into islet-like clusters when cultured in vitro under appropriate conditions.

Aim To study the role and mechanism of opioid receptor on IL-1?-induced fever.Methods Rats were dealed with intracerebreventricular administration of naloxone and/or IL-1?.Changes in body temperature were measured.The content of cAMP and HSP70 expression in hypothalamus were detected.Results Naloxone can limit IL-1?-induced fever and decrease the content of cAMP and HSP70 expression in hypothalamus(P

Objective To examine the relationship between hematocrit and risk of long term mortality among patients with acute myocardial infarction. Methods A total of 274 patients with acute myocardial infarction were recruited and divided into two groups by death after long term follow-up, the relationship between hematocrit and mortality was evaluated through the methods of independent t-test,chi-square test and multivariate regression analysis. Results The mean age was 69. 79 ± 7.45 years, with 73. 0% of male. The average of followup was 44. 4± 10. 7 months, with mortality of 38.7% . Comparison of baseline data showed that NYHA classification, smoking history, hemoglobin, hematocrit, mean red cell volume, glomerular filtration rate, ejection fraction,left ventricular diastolic diameter and right ventricular diameter was significantly different between the two groups( Ps ＜ 0. 05), Multivariable logistic analysis showed that hematocrit ,glomerular filtration rate, ejection fraction and smoking history were independently predicted factors, with OR of 0. 904 (95% CI: 0. 832 - 0. 982,P =0. 016) ,0. 983 (95% CI: 0. 969 -0. 996,P =0. 014) ,0. 932 (95% CI: 0. 887 -0. 979,P =0. 005) and 3. 230 (95% CI: 1.468 - 7. 106, P = 0. 004), respectively. The power of hematocrit to predict mortality was examined by ROC curves, the area under the curve was 0. 669(P ＜ 0. 001,95% CI: 0. 603 - 0. 736) Conclusion Hematocrit is a significant independent predictor for long term death among patients with acute myocardial infarction.

Objective:The study is to compare the prevalence and related factors of suicidal ideation in ado-lescents between China and Philippine.Methods:Our research data was downloaded from the website of world health organization (WHO).It was the data of China and Philippine from the Global school-based student health survey(GSHS)which was launched by the WHO,and 9173 students in China and 7338 students in Philippine aged 11 -16 years were involved.The situations of being serious injury,being bullied,sense of loneliness,insomnia, sense of hopelessness,friends,smoking,alcohol consumption,drug abuse and exercise were assessed by the ques-tionnaire.The definition of suicidal ideation was that ever thinking of suicide seriously in the last 12 months.Results:The rate of having suicidal ideation in China and Philippine were 17.4% (1544 /8881 )and 19.3% (1371 /7089),respectively.Multivariate analysis showed that female (OR =1.45),grade two and three of middle school (OR =1.29,1.43),being serious injury (OR =1.35),being bullied (OR =1.87),sense of loneliness (OR =1.47),insomnia (OR =1.55),sense of hopelessness (OR =3.36),alcohol consumption (OR =1.45)and drug abuse (OR =1.55)were the risk factors to suicidal ideation in China adolescents,and having good friends (OR=0.66)and exercise regularly (OR =0.78)were the protective factors.However,the female,grade,sense of lone-liness,insomnia and drug abuse were not the risk factors to suicidal ideation in Philippine adolescents,and other fac-tors were similar to China sample.Conclusion:There may be differences in the prevalence rate of suicidal ideation between adolescents in China and Philippine,with lower rate in China.Meanwhile,there are similarities in the relat-ed factors on the adolescent suicidal ideation of the two countries,with more risk factors in China sample.Therefore,the individualized targeted measures should be taken to prevent suicide in China and Philippine respectively.
