Objective To assess the ability of interleukin-1 beta (IL-1?) antibody and tumor necrosis factor alpha (TNF?) antibody to prevent postoperative abdominal adhesion formation in mice.Methods 60 BALB/c mice were randomly divided into four groups: normal saline group(n=15), anti-IL-1? group(n=15), anti-TNF? group(n=15),and anti-IL-1? combined with anti-TNF? group(n=15). After an identical peritoneal injury operation, mice were treated using intraperitoneally with either normal saline or corresponding antibody at the time of abdominal closure. The mice were killed 20 days after operation, the abdominal incisions and the development of intra-abdominal adhesions were observed. Adhesion scoring was based on an overall assessment of the extent,location, and type of adhesion.Results Anti-IL-1? combined with anti-TNF? group had significantly lower adhesion scores (0 84?0 19) than that in other groups(P

Objective To evaluate the clinical value of laparoscopic nephrectomy. Methods Laparoscopic nephrectomy was used in 26 cases (transperitoneal approach in 19 cases and retroperitoneal approach in 6 cases), including 8 cases of radical resection of renal cancer, 7 cases of total resection of kidney and ureter (2 cases of carcinoma of renal pelvis and 5 cases of carcinoma of ureter ), 6 cases of non-functioning or atrophic kidney and 5 cases of living donor nephrectomy. Results All the operations were accomplished successfully. The operative time was 120 min ～ 250 min (mean, 190 min) and the intraoperative blood loss was 50 ml ～ 200 ml (mean, 130 ml). No blood transfusion was needed and no operative complications occurred. Follow-up for a mean of 16 months in 8 cases of renal cancer and 20 months in 7 cases of total resection of kidney and ureter revealed no recurrence or metastasis except for 1 case of local recurrence of ureteral carcinoma. Conclusions The laparoscopic nephrectomy has the advantages of minimal invasion, less blood loss and rapid recovery.

Objective To investigate the preventive effects of phytosterol on lipid metabolic disturbance of rats fed with high-fat diet. Methods Forty male SD rats were randomly divided into control group (fed with basic diet), high-fat model group (fed with high-fat diet), low phytosterol group( fed with high-fat diet and 100 mg/kg phytosterol) and high phytosterol group( fed with high-fat diet and 200 mg/kg phytosterol). Body weight, serum lipid, liver fat and body fat were measured at the end of experiment (6 weeks later). Results At the end of experiment, the body weight, contents of liver fat and body fat and serum TC, TG and LDL-C levels were significantly higher in high-fat model group, low phytosterol group and high phytosterol group than those in control group (P <0.05), while serum HDL-C levels in these three groups were significantly lower than that in control group (P < 0.05). Compared with high-fat model group, the body weight gain and content of body fat of high phytosterol group were significantly lower (P <0.05). The contents of liver fat and serum TC, TG and LDL-C levels in low phytosterol group and high phytosterol group were significantly lower than those of high-fat model group (P < 0.05). Conclusion Phytosterol could prevent lipid metabolic disturbance of rats fed with high-fat diet. High dose phytosterol has the potential to reduce the body weight gain and contents of body fat of rats fed with high-fat diet.

Objective To investigate the clinical effects of laparoscopic sleeve gastrectomy with duodenaljejunal bypass (LSG + DJB) for the treatment of type 2 diabetes mellitus.Methods The clinical data of 17 patients with type 2 diabetes mellitus who underwent LSG + DJB at the Xijing Hospital of the Fourth Military Medical University from March 2013 to February 2014 were retrospectively analyzed.The fasting blood glucose,postprandial 2-hour blood glucose,glycosylated hemoglobin (HbA1c) and body mass index (BMI) in 17 patients before operation were (9.2 ± 0.6) mmol/L,(14.4 ± 2.2) mmol/L,8.3％ ± 1.2％ and (29.4 ± 2.2) kg/m2,respectively.All the patients received LSG + DJB and were followed up by outpatient examination up to March 2015.The pre-and post-operative 12-month fasting blood glucose,postprandial 2-hour blood glucose,HbA1 c and BMI in 17 patients were compared.Measurement data with normal distribution were presented as-x ± s and analyzed by the t test.Results All the 17 patients received successful laparoscopic LSG + DJB without conversion to open surgery.The operation time,volume of intraoperative blood loss and recovery time of postoperative gastrointestinal function were (141 ±53)minutes,40 mL and 2.5 days.Of 3 patients with postoperative complications,1 patient with anastomotic leakage at postoperative day 5 received reoperation by laparoscopic Roux-en-Y gastric bypass,1 patient with digestive tract obstruction at postoperative day 10 released obstruction by reoperation and 1 patient with left subphrenic abscess and leakage at the upper of the stomach at postoperative week 2 was cured by the symptomatic treatment.The duration of hospital stay was 5.2 days.All the patients were followed up for a median time of 16 months (range,13-24 months).The postoperative 12-month fasting blood glucose,postprandial 2-hour blood glucose,HbA1c and BMI in 17 patients were (5.5 ± 0.7)mmol/L,(8.8 ± 1.7)mmol/L,5.1％ ± 0.7％ and (24.7 ± 2.3)kg/m2,which were significantly different from preoperative indicators (t =19.96,10.52,12.06,31.99,P ＜ 0.05).During the follow-up,no anastomotic ulcer and stenosis,dumping syndrome and severe malnutrition were occurred.Conclusion LSG + DJB is safe and feasible for the treatment of type 2 diabetes mellitus,with a good short-term hypoglycemic effect.

Mixure lymphocyte culture demonstrated that homograft rejection reaction was inhibited markedly. Conclusion Intrauterine injection of rat fetal hepatocytes wuld obviously inhibite homograft rejection reaction, thus prolonging survival time of the graft.

BACKGROUND: Having breakfast everyday is a behavior promoting health recommended WHO, while it is easy to be ignored.OBJECTIVE: To investigate the breakfast habits of pupils in Beijing and Shanghai so as to provide a scientific basis for further studying the problems in having breakfast among the pupils, drafting and developing "nutritious breakfast program for students".DESIGN: Stratified and cluster sampling and investigation study were used based on the pupils.SETTING: Institute of health for child of two universities.SUBJECTS: A total of 8688 six to eleven years old Beijing and Shanghai pupils were involved from March 2002 to June 2002. Among them 4692 pupils came from Beijing. There were 4637 valid questionnaires, 2386 of which were from male pupils and 2251 from female pupiIs. Among the total subjects, there were 4300 Shanghai pupils, and 4051 questionnaires were valid, of which 2031 were from the male pupils and 2020 from female students.METHODS: A self-administered questionnaire survey was conducted. The content of the questionnaire included the general conditions of the family, dietary preferences, food for breakfast, consumption of the milk food and so on.RESULTS: The results showed that about 25.8% boys and 21.6% girls in Beijing did not eat breakfast regularly; similarly, the percentage was about 11.4% for boys and 13.3% for girls in Shanghai. The reasons for not having breakfast included the following: They had no appetite, or had no enough time for it, or the parents were too busy to prepare in the mornings. For those of them who eat breakfasts, the nutrients of their breakfast usually were not adequate. 55% of the students had their breakfast prepared by their mothers. As for the eating sites, students mainly ate at home; the next was having it on the way to school or eating at the roadside luncheonettes. The cost of breakfast was 2 - 3 yuan. The breakfast behaviors of the pupils were closely related with the behaviors of their mothers( r = 0. 4333, P < 0.01 ).CONCLUSION: It is suggested that quality of breakfast of the pupils need to be improved. The behaviors of the parents influence their children in breakfast habits.

Objective To construct a RhoA-siRNA expression vector and determine its role on the malig-nant behavior of HepG2 cells.Methods A RhoA-siRNA DNA fragment was synthesized and cloned into the expression vector of pGenesil-1.The constructed Rhon-siRNA DNA plasmid was stably transfected into HerG2 cells by lipofectamine,and then HepG2 cells were divided into the HepG2/RhoA-siRNA group (HepG2 cells were transfected with pGenesil-1-RhoA-siRNA),HepG2/control group(HepG2 cells were transfected with control plasmid) and HepG2 group (without plasmid transfection).The inbibitory effect of RhoA-siRNA on RhoA protein expression was shown by Western blot.The proliferation,migration,growth potentiality and cell cycle of transfected HepG2 cells were evaluated by MTT assay,wounded healing,the plate cloning formation test and flow cytometry,respectively.All data were analyzed by one-way analysis of variance (ANOVA) and chi-square test.Results The expression of RhoA protein in the HepG2/RhoA-siRNA group was,significantly decreased compared with that in the other two groups (F=178.19,P<0.05).Scratched cells were healed within 48 hours in the HepG2/control group and HepG2 group,but not in the HepG2/RhoA-siRNA group.The clone formation rates in the HepG2/RhoA-siRNA group,HepG2 group and HepG2/control group were 39%±3%,67%±5%and 70%±6%,respectively,with a significant difference among the three groups(χ2=33.34,38.69,P<0.05).Flow cytometry showed that the number of cells transfected with RhoA-siRNA was highest in the G0/G1 phase and lowest in the S phase(F=70.46,76.57.P<0.05).Conclusion The RhoA-siRNA expression vector can effectively suppress the proliferation and migration of HepG2 cells,which may provide a novel gene therapy for hepatocellular carcinoma.
