Objective To investigate the effect of atorvastatin and rosuvastatin on endothelial function in diabetics with coronary heart disease. Methods A total of 73 consecutive diabetics with coronary heart disease who were not receiving statins were randomized to receive atorvastatin 20 mg/d or rosuvastatin 10 mg/d. The levels of lipids, high-sensitivity C-reactive protein(hs-CRP), monoxide nitrogen(NO), endothelin-1 (ET-1) and endothclium-dependent relaxing function(EDF) were assessed before and after 3 months of the treatment. Results The treatment with statins significantly improved endothelial function in diabetics with coronary heart disease. For both rosuvastatin group and atorvastatin group in pro-treatment versus post-treatment, EDF was higher[(5.2±2.4)% vs. (7.9±3.1)%, P=0.008; (5.0±2.8)% vs. (7.6±3.6)%, P=0.024, respectively], NO was also higher((46.6±14.5) μmmol/L vs. (73.3±18.5) μmmol/L; (51.7±14.0) μmmol/L vs. (79.8±16.0) μmmol/L,both P<0.001], ET-1 was lower[(108.2±29.6) pg/L vs. (77.5±26.4) pg/L, P =0.005;(117.1±34.5) pg/L vs. (80.7±28.2) pg/L, P= 0.003, respectively],and hs-CRP was lower[3.17(1.33～6.32) mg/Lvs. 1.39(0.81～2.58) mg/L, P=0.006; 3.43(1.51～7.02) mg/L vs. 1.63(0.69～3.11) mg/L, P = 0.001, respectively]. There were no differences in these between rosuvastatin group and atorvastatin group. Significant negative correlation existed between EDF and hs-CRP. Conclusions A 3 months treatment with either atorvastatin 20 mg/d or rosuvastatin 10 mg/d is effective in improving endothelial function in diabetics with coronary heart disease.

Translationally controlled tumor protein (TCTP)is a small protein highly conserved in a variety of eukaryotic species.TCTP is overexpressed in various tumor cells and has been implicated in the regu-lation of cellular processes including apoptosis,DNA repair and drug resistance.By reviewing the recent pro-gress of TCTP research,TCTP is becoming an important regulator of DNA repair and a new molecular target for tumor therapy.

Objective To analyze the common causes leading to lung infection following renal transplantation and provide targeted preventive measures to reduce the incidence of lung infection.Methods The clinical data of 561 recipients who underwent renal transplantation from January 2006 to February 2011 were retrospectively analyzed.The recipients were divided into two groups:group Ⅰ,from January 2006 to December 2009 (n =416) ; group Ⅱ,from January 2010 to February 2011 (n =145).The causes possibly leading to lung infection which took place 3 days before the appearance of the clinical symptoms were offered by the patients who suffered lung infection of group Ⅰ.And then the causes were summarized and analyzed to formulate the specific and comprehensive measures to prevent the infection.Finally the measures were applied to recipients in group Ⅱ from January 2010.After applying the measures for 14 months,the incidence of lung infection in group Ⅱ was counted and compared with that in group Ⅰ to see the preventive effect.Results There were 58 cases of lung infection in group Ⅰ (58/416,13.9％) and 12 cases in group Ⅱ (12/145,8.3％). There was significant difference in the incidence of lung infection between two groups (x2 =4.0361,P＜0.05).All of the recipients with lung infection were hospitalized in six months after the transplantation.The causes leading to lung infection of 58 cases in group Ⅰ were as follows:6 cases due to being excessively tired,3 cases due to guest visiting,12 cases due to abrupt change of weather,9 cases due to exposure to public place,8 cases due to returning to hospital,6 cases due to close contact with children,5 cases due to close contact with animals,and the other 9 cases without specific causes found.Conclusion The incidence of lung infection following renal transplantation can be notably reduced by the application of targeted and concrete health propaganda education and preventive measures based on analysis on the specific causes of infection.

Objective To understand health seeking behaviors and influencing factors among freshmen before enrollment in Kunming Medical University in Yunnan Province and to find out the existing medical problems and provide advice to guarantee undergraduates' seeking proper treatment. Methods We used cluster sampling method to select 1044 freshmen whose last digit of student number was singular and questionnaire was used to do the survey which was conducted within 3 months of admission. Statistical methods were descriptive statistics and multivariate logistic regression analysis. Results The main reasons for students to see the doctor were acute diseases (29.4%) and common disease dominated by cold and fever (34.9%), most of the students went to the medical institutions because of mild medication which can be treated by taking pills. Family location for rural areas had small number of students to see the doctors, the number of students seek medical services with low income families were larger than the high counterparts;students had poor perceived health status tended to seek medical services. Conclusions Family location, incomes and perceived health status are important factors influencing health seeking behavior. The current medical insurance system for college students could be further improved, and colleges and universities should take appropriate measures to provide the conditions for students to seek proper treatment.

Objective To observe the protective effect of Apelin-13 on the cerebral ischemia-reperfusion injury (CIRI), and to explore the possible mechanism in rat model. Methods Fifty male SD rats were randomly divided into five groups:sham group, CIRI model group and Apelin-13 (0.1, 1.0 and 10.0 μg/kg) treatment groups. The model of CIRI was established by filament. After 2 h ischemia, the focal middle cerebral artery was followed by 72 h reperfusion. Apelin-13 was administrated by intracerebroventricular injection 30 minutes before reperfusion. The score of neural function was estimated in different time points. The 2,3,5-triphenyl tetrazolium chloride (TTC) dye was used to calculate the volume and percentage of cerebral infarction. The endoplasmic reticulum stress (ERS) protein markers including glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in cerebral cortex were measured by Western blot assay. Results Compared with the sham group, the score of neural function was significantly increased, the infarct rate was reached(47.63 ± 5.81)%and the protein expressions of GRP78 and CHOP were significantly up-regulated in CIRI model group (P＜0.05). There were no significant differences in these data between the CIRI model group and 0.1 μg/kg Apelin-13 treatment group (P＞0.05). Compared with the CIRI group, the neural function defect was significantly improved, the muscle strength was significantly enhanced and the infarct rate was significantly decreased, and the protein expressions of GRP78 and CHOP were significantly down-regulated in the 1.0 and 10.0 μg/kg Apelin-13 treatment groups (P＜0.05). Conclusion Apelin-13 protects the cerebral ischemia-reperfusion injury in rat model, which may be related with the inhibition of endoplasmic reticulum stress.
