Objective: To study the hypoglycemic action in diabetic rats by soluble polysaccharides (A), protein components with molecular weights above 60 ku (B),3-60 ku(C) ,and below 3 ku(D) of some pumpkin seeds,arginine(E)and pumpkin seed oil(F). Methods: Ten rats were selected randomly as control ,while the other 150 rats were injected with alloxan 170 mg/kg to induce diabetes.The diabetic rats were divided into 15 groups:the model,A(1000,500 mg/kg),B(300,150 mg/kg),C(300,150 mg/kg),D(300,150 mg/kg),E(100,50 mg/kg),F(300,150 mg/kg),Gilbenclamide(20 mg/kg).The above components were given intragastrically for 10 d and then blood samples were taken to determine serum glucose and insulin, and also to test the glucose tolerance. Results: It was indicated in diabetic rat that the blood insulin level was obviously increased by the soluble polysaccharides , the protein components with molecular weight over 60 ku and below 3 ku after 4 d germination. The blood glucose tolerance was improved by seed oil, protein components with molecular weights 3-60 ku and arginine. Conclusion: The protein components with molecular weights about 3-60 ku have the best hypoglycemic action, in terms of improving the blood glucose tolerance and decreasing the blood glucose level of diabetic rats.

Objective: To study the effects of ginger oleoresins(GO) on blood lipids in hyperlipidemic mice and the platelet aggregation in rats.Methods: The rat platelet aggregation was induced by ADP and AA in vitro, and the inhibition by GO was tested by light transmission. The animal model of hyperlipidemia was establised by feeding Kunmimg mice with high lipid feed stuff. The effects of GO on serum lipid and hepatic MAD in hyperlipidemic mice was investigated. Results: GO could effectively inhibit rat platelet aggregation induced by ADP and AA in vitro, which were 58.9%,97.5% respectively, and in dose dependant manner. Besides, GO could also significantly decrease serum TC, LDL, AS index and hepatic MDA in hyperlipidemic mice, which were 16.45%, 60.45%,37.30% and 54.27% respectively, and showed no side-effect on liver. Conclusion: Long-term consumption of GO can effectively modulate blood lipids, prevent thrombosis and AS.

Objective: To explore the effect of exercise preconditioning (EP) on pathological cardiac hypertrophy and heart failure (HF) in pressure over-loaded experimental rats.
Methods:A total of 60 SD rats at the age of 6 weeks were randomly divided into 3 groups, n=20 in each group. Sham-operation group, Transverse aortic constriction (TAC) group and EP + TAC group. The cardiac function and structure were evaluated by echocardiography, patholgical changes and HF biomarkers were examined for EP effect at 4 and 8 weeks after TAC.
Results:Compared with Sham-operation group, the cardiac function and structure had obvious changes in the other 2 groups. Compared with TAC group, the ejection fraction in EP+ TAC group increased 15%, the heart weight index and left ventricular weight index decrease 15.7%and 20%respectively at 8 weeks after TAC, all P<0.05. Compared with Sham-operation group, the mRNA and protein expressions of ANP and BNP increased in TAC group at 4 and 8 weeks after TAC, increased in EP+TAC group at 8 week after TAC. Compared with TAC group, the mRNA expressions of ANP and BNP in EP+TAC group decreased 47%and 62%at 4 weeks after TAC, decreased 44%and 28.1%at 8 weeks after TAC, all P<0.05;the protein expression of ANP and BNP in EP+TAC group decreased 22.3%and 48%at 4 weeks after TAC, decreased 21.5%and 38.3%at 8 weeks after TAC, all P<0.01.
Conclusion: EP may improve cardiac pathological hypertrophy in pressure over-loaded rats at the early stage, and delay the heart failure process.

Objective To observe the feasibility of 125I intra-operative implantation plus palliative resection of gastric carcinoma for treatment of advanced gastric cancer infiltrating pancreas. Methods 125 I was implanted intraoperatively into the residual pancreatic cancer tissues after gastric carcinoma was palliatively removed. Results From Feb. 2005 to Jun. 2009, 15 cases (9 male, 6 female) advanced gastric cancer patients were treated with 125 I intra-operative implantation. The patients' ages ranged from 41 to 78 years, with the median age of 64 years old. There were 10 cases of gastric cancer infiltrating the neck or body of pancreas and 5 cases infiltrating pancreatic head. No severe post-operative complications were recorded. The follow-up showed that there were 5 cases of CR (33.3%), 9 cases of PR (60%), 1 case of NC (6.7%) and no PD patients were found. Conclusion 125I intra-operative implantation plus palliative gastric resection is feasible and effective for patients of advanced gastric cancer infiltrating the pancreas.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
