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 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 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.

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 investigate the nutrition statuses of thiamine and riboflavin and their relationship with the antioxidant capacity and blood glucose and lipids levels in the middle-aged and elderly. Methods Totally 314 subjects aged above 40 years old from communities in Shanghai were enrolled. The 3-day survey of 24-hour's diet recall was made to evaluate the daily nutrient intakes using a nutrition assessment software provided by CDC China. Thiamine and riboflavin levels were detected by urine load test. Fasting blood glucose ( FBG), total choles-terol (TC), triglyceride (TG), superoxide dismutase (SOD) activity and malondialdehyde (MDA) were deter-mined by commercial kits. Results The average daily intakes of thiamine and riboflavin were (0. 82 + 0. 36) and (0. 91 +0.48) rag, respectively. The middle-aged and elderly whose intakes of thiamine and riboflavin reached recommended nutrient intake (RNI) level accounted for 11.8% and 17.2%, while those lower than 60% RNI ac-counted for 51.3% and 49. 4%, respectively. Urine load test showed the deficiency rates of thiamine and ribofla-vin were 65.0% and 58.6%, respectively. Compared with the normal group, plasma MDA, FBG, TC, and TG levels progressively increased and SOD activity decreased in insufficient and deficient groups; the plasma MDA, FBG, and TC levels were significantly different between normal group and thiamine deficient group ( P < 0. 05 ).The FBG and TC levels were negatively correlated with the status of thiamine ( r = - 0. 246, r = - 0. 154, P <0. 05). The MDA and TG levels were negatively correlated with the status of riboflavin ( r = - 0. 136, r =-0. 297, P <0. 05). Conclusions The nutrition statuses of thiamine and riboflavin are poor in the middle-aged and elderly in Shanghai. The nutritional statuses of thiamine and riboflavin are positively correlated with the antioxi- dant capacities and are negatively correlated with the level of FBG, TC, and TG.

Objective To study the relationship between trace elements and blood lipids and glucose in Shanghai adults. Methods Totally 245 subjects aged above 18 years from two communities in Shanghai were en-rolled into this study. Blood trace elements (Fe, Zn, Cu, Mg, Pb, Mn, and Cd) were examined with atom ab-serption spectrophotometry. Body mass index (BMI), waist hip rate (WHR), and blood pressure (SBP, DBP)were also determined. Results Compared with the normal control group, plasma Fe and Mn levels were signifi-cantly lower while Zn and Zn/Cu levels were significantly higher in hyperlipemia group (P <0.05 or P <0. 01 ) ;plasma Zn, Zn/Cu, and Mn levels were significantly lower while Cu and Pb levels were significantly higher in dia- betes mellitus group (P <0. 05 or P <0. 01 ) . A tendency of lower Mg and higher Cd levels were also found in both disease groups, but there were no statistical significance ( P >0. 05 ). Conclusions The metabolism of trace elements is abnormal in patients with hyperlipemia and diabetes mellitus. Intervention of these trace elements disor-der may be valuable in the prevention and treatment of these diseases.
