Objective To determine the effects of Sodium Nitroprusside ( SNP) , superoxide dismutase ( SOD) and catalase ( CAT ) on the expression of catalytic subunit of the DNA-dependent protein kinase ( DNA-PKcs ) and Ku70/80 heterodimer in cardiomycyte H9C2, as well as their expression in the myocardial tissues of SD rats . Methods H9C2 cells were co-cultured with SNP at concentreations of 10, 20 and 40 mmol/L for 6 hours, SD rats were injected with normal saline , SNP, SNP+SOD, SNP+CAT or SNP+SOD+CAT.Western blot and immuno-histochemistry assay were used to examine DNA-PKcs and Ku70/80 protein expression respectively .Results The expression of DNA-PKcs and Ku70/80 increased in H9C2 cells co-cultured with SNP when compared with control group, but they were be decreased when treated with SOD or/and CAT.The expression of DNA-Pkcs and Ku70/80 in myocardial tissues of experimental groups were higher than the control .Conclusions Radical scavengers may play a role as a protective effect for sodium nitroprusside related injury in cardiac myocytes .

Objective To observe the protective effect of Naoli Zhibao(NZ) on mice with learning and memory impairment.Methods (1) Thirty-two NIH mice were randomized into pseudo-operation group,model group,and low-and high-dose NZ groups(at the dose of 4 and 8 g?kg-1?d-1 respectively).Except the pseudo-operation group,the mice in other groups received the operation of cerebral ischemia/reperfusion.After treatment for 10 days,the learning and memory abilities of the mice were observed by step-down test,and the contents of malondialdehyde(MDA) and nitric oxide(NO) as well as the activities of superoxide dismustase(SOD) and glutathione peroxidase(GSH-Px) were detected.Meanwhile,the free amino acid content in mice cerebral cortex was measured with high performance liquid chromatography.(2) Forty NIH mice aged 9 months were randomized into normal control group,mimetic aging group,and low-and high-dose NZ groups(at the dose of 4 and 8 g?kg-1?d-1 respectively).The mice models of mimetic aging were induced by intraperitoneal injection of D-galactose 0.5mL for 6 weeks,and the mice in NZ groups were also given gastric gavage of NZ for 6 weeks.After treatment,the learning and memory abilities of the mice were observed by step-down test,and the contents of epinephrine(E),norepinephrine(NE) and tryptophan(TP) in mice cerebral cortex were measured.Results (1) NZ significantly improved the memory ability of mice with cerebral ischemia/reperfusion injury(P

Objective: To develop the national norms of ISCA (intelligence scale for Chinese adult) for urban adults aged 16 to 64 years and examine its psychometric characteristics. Methods:The ISCA standardization was completed on 1600 adult subjects. Year 2000 Census data was applied to the standardization sample in order to correctly represent individuals by age, gender, educational level, geographic region, and occupation. Results:The ISCA had good reliability( test-retest coefficients of Full scale IQ was 0.96, the average spilt-half reliability for the IQ scales ranged from 0.93 to 0.96 and the average standard error of measurement of subtest ranged from 1.04~1.88, rater reliability 0.91~0.96). The total score of ISCA relates that of the WAIS-RC, WAIS-III revised in Taiwan, and CRT-C2 are 0.94, 0.90, 0.69, respectively (P

0.6). And there was high internal consistency in major instruments. The validity was examined by comparing the responses of informants and responses (good standards) of the target person in normal control group. There was also a high validity(r=0.21~0.61).Conclusion: The information reconstructed from the informants has good reliability and validity. It is possible to study suicide with psychological autopsy in China.

Objective To summarize the experience of laparoscopic appendectomy(LA). Methods A retrospective analysis was made on clinical date of 368 cases of appendicitis treated with laparoscopic appendectomy in this hospital from March 1998 to March 2005.There were 35 cases of simple appendicitis,276 cases of suppurative appendicitis,39 cases of appendiceal perforation with peritonitis,and 18 cases of chronic appendicitis. Results The procedure was successfully accomplished in 363 cases,while conversions to open surgery were performed in 5 cases.The operative time was 22~55 min(mean,30.5 min),and the intraoperative blood loss was 2~10 ml.One case of abdominal residual infection and 1 case of adhesive ileus were cured with conservative treatment postoperatively.Pelvic abscess occurred in 1 case and was cured with a re-operation of laparoscopic abscess drainage. Conclusions Laparoscopic appendectomy is safe and effective in skilled hands.

Objective To study the effects of isotonic and resistance exercises on renal hormones in plasma. Methods Eight healthy men were instructed to performed isotonic and resistance exercises, respectively, with the same target heart rate and the same exercise duration, in which both exercises-induced changes of plasma renin activity (PRA), aldosterone (ALDO) and antidiuretic hormone (ADH) were observed. Results Plasma levels of PRA, ALDO and ADH increased significantly after both isotonic exercise and resistance exercises. Plasma levels of ADH and PRA were higher after resistance exercise than those after isotonic exercise. Conclusion The increases of PRA, ALDO and ADH in plasma caused by exercise might be an adaptive response to maintain balances of water and electrolyte in the status of physical stresses. The tendency of increase of ADH and PRA after resistance exercise suggested that the exercise intensity rather than type of exercise correlated with on the changes of renal hormones.
