Objective To evaluate physiologic ability and surgical stress (E-PASS) for predicting postoperative complications in patients undergoing elective colonic surgery. Methods The clinical data of 158 patients with colonic cancer who were admitted to the West China Hospital from August to October, 2009 were retrospectively analyzed. E-PASS was applied to evaluate the surgical risk. Three indexes of the E-PASS system,including preoperative risk score (PRS), surgical stress score (SSS) and comprehensive risk score (CRS) were compared with actual postoperative outcomes. Correlation between PRS, SSS, CRS and postoperative risks was analyzed using multiple linear regression analysis. Results Of the 158 patients, 27( 17.1% ) had postoperative complications, and the predictive value was 19.4% ± 2.0% according to the E-PASS. Dukes stages, physical performance indexes, severe heart disease, severe pneumonia disease, length of operation time were correlated with the incidence of complications (r = 0. 193, 0. 410, 0. 183, 0. 174, 0. 198, P ＜ 0.05). PRS, CRS and SSS had good predictive effect on postoperative risks (r = 0. 299, 0. 349, 0. 183, P ＜ 0. 05 ). Conclusions E-PASS system is a relatively simple, fast and user friendly tool for predicting the risk of short-term postoperative complications.

ObjectiveToexplorethedynamicchangesofoxidativestressandcytokinesinMongoliangerbilswith nonalcoholic fatty liver disease ( NAFLD) and their significance.Methods Forty-eight healthy male gerbils were randomly divided into normal group and model group , 24 in each group .Gerbils of the model group were fed with high fat diet while those of the normal group with normal diet .Eight gerbils in each group were killed at the end of 4 w, 8 w and 16 w, respectively .MDA content and SOD , GSH-PX and T-AOC activity in the liver tissue were detected by chemical method, and serum TNF-α, INF-γand IL-10 levels were determined using liquid suspension chip .Results With the development of NAFLD , MDA content in liver increased gradually , and the MDA contents were all significantly higher than those of the normal group ( P<0.01 ); T-AOC level slightly increased , and then decreased , the levels at 4 w and 16 w were markedly decreased compared with those of the normal group (P<0.05);SOD level was significantly increased and then markedly reduced, the level of the model group at 4 w was significantly increased (P<0.05), while that at 8 w and 16 w were significantly decreased (P<0.05, P<0.01).The level of GSH-PX was decreased gradually , the levels at 8 w and 16 w were significantly lower than those of the normal group (P<0.05).With the progression of NAFLD,serum TNF-αand IFN-γwere increased gradually , while the level of IL-10 decreased gradually , and the levels at 8 w and 16 w were significantly lower than those of the normal group ( P <0.05, P <0.01).Conclusions The oxidative stress-related indicators and inflammatory cytokines in the gerbil NAFLD models induced by high fat diet are significantly changed as simple fatty liver develops into steatohepatitis , liver fibrosis and cirrhosis , and participate in the development and progression of NAFLD .

Objective To investigate the effects of levodopa benserazide hydrochloride combine with dl-3-butyl phthalide capsule on patient's limbs function after stroke. Methods Ninety patients with stroke were randomly divided into rehabilitation group,treatment group and control group,and 30 cases for each group. Patients in rehabilitation group were treated with exercise therapy,in treatment group were given exercise therapy and levodopa Benserazide and Dl-3-butylphthalide capsules,and in control group were given placebo treatment. Adult hemiplegic motor function score(FMA)and motor function assessment scale(MAS)were used to assess the motor function and lower extremity function before treatment and 8 weeks after treatment. Results Before treatment,FMA and MAS in rehabilitation group,treatment group and control group were(22. 6 ± 3. 6), (23. 1 ± 2. 5)and(20. 3 ± 2. 9),and(1. 6 ± 0. 6),(2. 1 ± 0. 5),(1. 7 ± 0. 9),respectively. There was no significant differences between the two groups( F = 1. 64,P > 0. 05;F = 1. 66,P > 0. 05). After 8 weeks of treatment,FMA and MAS in rehabilitation group and treatment group were(60. 6 ± 3. 5),(14. 6 ± 1. 1),and (75. 7 ± 4. 5),(17. 7 ± 4. 5),significant improved more than that before treatment(t = 1. 738,1,716,1. 732 respectively;P < 0. 05). Meanwhile,patients in the treatment group improved more than that in rehabilitation group(P < 0. 05),and they were superior to patients in control group((31. 0 ± 3. 6),(5. 5 ± 1. 1);P < 0. 05). Conclusion Benserazide combined with dl-3- butyl phthalide capsule can further improve the limbs function.
