Objective To explore the role of somatostatin in protecting small-for-size liver after hepatectomy in rats with cirrhosis.Methods Forty-eight rats with cirrhosis were randomly divided into somatostatin group (group S,n =24) and normal saline control group (group N,n =24).All rats from the two groups were measured with baseline portal vein pressure and blood flow volume.Additionally,at the endpoints of 15,30 and 60 min after ischemia/reperfusion with hepatic inflow occlusion,portal vein pressure and blood flow volume were detected from both groups.Liver function test was also measured at the endpoints of 1,3,5,24 h after ischemia/reperfusion for groups S and N.Results After 15-min ischemia/reperfusion,the portal vein pressure was higher in the rats of group S than that in group N [(19.4 ± 0.8) cmH2O vs.(22.5 ± 1.2) cmH2O (1 cmH2O =0.098 kPa)],there was significant difference (P ＜ 0.05).After 30 min ischemia/reperfusion,portal vein pressure results were (17.1 ± 0.8) cmH2O and (19.7 ± 0.8) cmH2O in group S and group N,respectively,P ＜ 0.05.At different endpoints,portal blood flow volume results were all higher in both groups than baseline figures.Furthermore,maximum portal blood flow volume was observed at the endpoint of 15 min ischemia/reperfusion in both groups,and lower in group S than group N [(10.1 ±0.4)ml/min vs.(11.9 ±0.5)ml/min,P＜0.05].Liver function test revealed AST,ALT,TBil exceed normal limits in rats of both groups,which elevated along prolonged ischemia/reperfusion.One week after hepatectomy,the survival of rats treated with somatostatin (group S,7/10) was superior to saline control group (group N,2/10),P ＜0.05.Future liver volume increased in rats from both groups,much significant increase was determined in group S [(5.5 ± 0.4) g vs.(6.6 ± 0.3) g,P ＜ 0.05].Conclusions Somatostatin might improve portal vein hypertension status in the early stage of small-for-size liver after hepatectomy,and decrease portal blood flow.Furthermore,it could alleviate small-for-size liver injury associated with portal vein hypertension and hyperperfusion,and benefit liver regeneration and improve postoperative survival in rats with cirrhosis.

Objective To investigate the expression and clinical significance of AGR2 and Lgr5 in CRC and the corre-lation with clinical pathologic features. To evaluate the significance with combined detection of the clinical and patho-logical diagnosis of CRC. Methods AGR2 and Lgr5 expression were assessed in 70 cases of CRC and 20 cases of nor-mal tissues near the cancer by immunohistochemistry. Results ①The expression of AGR2 was significantly higher in CRC than that in normal tissue(68.57%vs 25.00%,P<0.01). The AGR2 expression in CRC was correlated with the de-gree of tumor differentiation and lymph node metastasis(P<0.05).②The expression of Lgr5 was significantly higher in CRC than that in normal tissue (74.29%vs 40.00%, P<0.01). The Lgr5 expression in CRC was correlated with the de-gree of tumor differentiation﹑depth of invasion and lymph node metastasis(P<0.05). ③The Area Under Curve(AUC) of combined detection of AGR2 and Lgr5 were significantly higher than detection of both alone. the difference was statis-tically significant (P all <0.05). Conclusion AGR2 and Lgr5 played an important role in the occurrence and develop-ment of CRC, the combined detection not only contribute to the judgment of tumor progression, but also provide theo-retical support for molecular diagnosis and treatment of patients with CRC .

Objective:To explore the effects of bariatric metabolic surgery on body composition.Methods:The retrospective cohort study was conducted. The clinicopathological data of 66 patients with metabolic diseases who were admitted to the Third Xiangya Hospital of Central South University from January 2013 to December 2014 were collected. There were 42 males and 24 females, aged (40±11)years, with a range from 17 to 63 years. Of the 66 patients, 27 undergoing laparoscopic sleeve gastrectomy (LSG) and 39 undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) were allocated into LSG group and LRYGB group, respectively. The body composition of all patients was determined by dual-energy X-ray absorptiometry at preoperation and postoperative 6 months. Observation indicators: (1) the changes of anthropometric parameters, glucolipid metabolism, body fat mass percentage (BF%) and the ratio of Android BF% and Gynoid BF% (A/G ratio) from preoperation to postoperative 6 months; (2) the changes of whole and local body composition from preoperation to postoperative 6 months; (3) analysis of the correlation between BF% and anthropometric parameters, glucolipid metabolism. (4) Follow-up. Follow-up was conducted using outpatient or hospitalization examination to detect the changes of body composition at the time of postoperative 6 month. The follow-up time was up to July 2015. Measurement data with normal distribution were represented as Mean± SD, paired-samples t test was used for intra-group comparison, and independent-samples t test when baseline data were consistency or covariance analysis when baseline data were not consistency was used for inter-group comparison. Measurement data with skewed distribution were represented as M ( P25, P75), and comparison between groups was analyzed using Wilcoxon signed rank test. The correlation test was undertaken with the Pearson bivariate analysis.
