Objective To investigate the features of transcatheter selective hepatic arteriography and efficacy of embolization in hepatic hemangioma. Methods Twenty-six patients of hepatic hemangioma underwent transcatheter selective hepatic arteriography and embolization with Lipiodol-ultrafluida as well as Pingyangmycin, and were followed-up for 3 - 12 months after treatment. Results The popcorn-like tumor stain sign and early fill-in and persistant staining sign of hepatic arterial angiography were observed in all patients before embolization. After one time of embolization, the tumor size decreased more than 25% in 22 patients (84.62%), less than 25% in 4 patients. No severe complication occurred. Conclusion Transcatheter selective hepatic arteriography and embolization is a favorable method of diagnosis and treatment for hepatic hemangioma.

Objective The goal of this study is to understand the function of FKBP51 in resistant to high fat diet-induced obesity using FKBP51 knockout ( KO) mice and in vitro adipocyte differentiation.Methods Four-week old male FKBP51 KO and wild type ( WT) mice were fed separately with regular or high fat diet for 6 weeks.The body weight and food consumption were recorded weekly, the energy expenditure differences ( O2 consumption, CO2 production, respiratory exchange ratio, and heat production) of each group were monitored using the MM-100 metabolism cages system for 24 hours, then the liver from the above animals were stained with the Oil red-O to detect the lipid accumulation and the expression of metabolic genes.In addition, induction of adipocyte differentiation of immortalized MEF cells from WT and FKBP51 KO mice were used to observe the effect of FKBP51 gene on lipogenesis.Results Compared to WT mice, FKBP51 KO mice has less weight increment, and less lipid accumulation in the liver, but with no difference on food consumption during high-fat diet fed.Moreover, FKBP51 KO mice exhibited more O2 consumption, CO2 production and heated production under both RD and HF diet conditions.The PEPCK, G6Pase and UCP-1 genes up-regulation.In addition, lipid content was reduced in FKBP51 gene deficient MEF cells after adipocyte differentiation.Conclusions The FKBP51 gene plays an important role in high fat diet-induced obesity through the energy metabolism enhancement and lipogenesis inhibition.

Objective To investigate the therapeutic effect and advantage of laparoscopic appendectomy by concealed three-ports technique. Methods The clinical data of 283 patients received concealed three-ports laparoscopic appendectomy were retrospectively reviewed. Results All the patients were cured after appendectomy,including 5 patients required conversion to operation(because of adhesions around the appendix and difficult to dissect). The surgical time ranged from 25 min to 110 min and the mean time was 38 min. After 8 ～ 12h the patients could move and the average length of postoperative stay was 5d (range 4 ～ 6d). 3 cases had postoperative wound infection. None occurred complications such as postoperative bleeding, abdominal abscess, intestinal fistula, adhesion ileus and incision hernia in 6 months on average (range 1 ～ 18 months)after operation. Conclusion Laparoscopic appendectomy by concealed three-ports technique was a safe and available method and had advantages such as convenience and safety,good cosmetic results,less injury,rapid recovery,less complications,cheap and easy.

Objective To investigate the strategies of nutritional therapy for severe acute pancreatitis (SAP) patients.Methods Two hundred and eight patients with SAP were randomly divided into early enteral nutrition (EEN) group,late enteral nutrition (LEN) group and total enteral nutrition (TPN) group.EEN group received enteral nutrition through nasojejunal tube feeding within 72 hours in the course of disease,LEN group received the same treatment after 6 d in the course of disease,TPN group received total enteral nutrition.The index of nutrition,incidence of complication were recorded,efficacy and safety were analyzed.Results EEN group included 67 cases,while 72 cases in LEN group and 69 cases in TPN group.The incidence rate of malnutrition after 14 d of treatment in EEN group and LEN group was significantly lower than that in TPN group [59.7％ (40/67),58.3％ (42/72) vs.84.1％ (58/69),P ＜0.05],but the difference between EEN group and LEN group was not statistically significant (P ＞ 0.05).There was no statistically significant difference in the incidence of hyperlipidemia and hyperglycemia among three groups (P ＞ 0.05).The expression level of albumin,prealbumin and retinol-binding protein after 14 d of treatment in three groups compared with those before treatment and the differences were statistically significant (P ＜ 0.05).The expression level of albumin,prealbumin and retinol-binding protein after 14 d of treatment in EEN group and LEN group compared with those in TPN group and the differences were statistically significant (P＜ 0.05),there was no statistically significant difference between EEN group and LEN group (P＞ 0.05).The incidence rate of total infections,abdominal infections,bloodstream infections,secondary superinfections in TPN group were significantly lower than those in EEN group and LEN group [62.3％(43/69) vs.25.4％ (17/67),19.4％(14/72) ;21.7％(15/69) vs.4.5％(3/67),6.9％ (5/72);39.1％(27/69) vs.14.9％(10/67),11.1％(8/72) ;33.3％ (23/69) vs.9.0％ (6/67),9.7％(7/72),P ＜ 0.05],there was no statistically significant difference in the incidence of peripancreatic infections,lung infections among three groups (P ＞ 0.05).There was no statistically significant difference in the incidence of total infections,different infections between EEN group and LEN group.There was no statistically significant difference in the incidence of noninfections among three groups (P ＞ 0.05).The rate of recovery in EEN group and LEN group was significanby higher than that in TPN group [91.0％ (61/67),94.4％ (68/72) vs.81.2％ (56/69),P ＜ 0.05],but the difference between EEN group and LEN group was not statistically significant (P ＞ 0.05).Conclusion Early enteral nutrition therapy for SAP patients is safe and effective,and could significantly improve the prognosis of patients.

Objective: To investigate the protective effect of rhubarb (大黄) combined with scopolamine on gastric and gut mucosal barrier in patients with severe trauma. Methods: Forty patients with severe trauma, injury severity score (ISS)≥25, were randomly divided into two groups (each n=20), namely common therapy group (CM group) and rhubarb (infused into stomach) combined with scopolamine group (RS group). In RS group, rhubarb combined with scopolamine were given just after the first time measuring gastrointramucosal pH (pHi), the other treatment was the same as CM group.The mean arterial pressure (MAP) and heart rate (HR) were recorded, and pHi, lactic acid, interleukin-6 (IL-6) and tumor necrosis factor-? (TNF-?) were measured on admission and at 24, 48 and 72 hours after admission. Results: The MAP, HR and pHi were uptrend in both groups. There were significant increase in MAP and pHi of RS group at 72 hours compared with those of CM group (both P
