AIM: To study the effects of guava polysaccharides on blood glucose level and antioxidant activity in alloxan-induced diabetic mice. METHODS: The animal model of diabetes was established by injecting alloxan into mice abdominal cavity.The mice were divided into five groups: normal control group,diabetic model group,guava polysaccharides group I,guava polysaccharides group II,glybenclamide group.Blood glucose level was determined with blood glucose monitor 3 d and 10 d after being given polysaccharides.The mice were anaesthetized and killed on the tenth day.Activity of SOD and concentration of MDA in blood serum and liver were determined. RESULTS: Compared with diabetic model group,the blood glucose level of guava polysaccharides group I and guava polysaccharides group II significantly decreased.Activity of T-SOD in blood serum and liver significantly increased,while concentration of MDA in blood serum and liver significantly decreased. CONCLUSION: Guava polysaccharides can significantly decrease blood glucose level and improve the antioxidant activity of diabetic mice.lt is a potential hypoglycemic agent.

Objective To evaluate the therapeutic effects of the integration of impaction bone grafting reconstructing femur trochanter and femoral head arthropalsty in the treatment of unstable intertrochanteric fractures in aged patients. Methods From January 2006 to December 2008,21 cases unstable intertrohanteric fractures with serious osteoporosis were treated with impaction bone grafting reconstructing the femur trochanter and femoral head arthropalsty. Results Functional assessment based on the Harris score ,great in 14 cases, good in 5 cases, medium in 2 cases. The excellent and good rate was 90. 4%. Conclusion The integration of impaction bone grafting reconstructing femur trochanter and femoral head arthropalsty is convenient to treat unstable intertrochanteric fractures in aged patients.

Currently, platelet transfusion is the primary treatment for thrombocytopnia which results from intensive chemotherapy and radiotherapy of cancer. While repeated platelet transfusions are associated with several problems. The clinical availability of safe and effective platelet growth factors is eagerly awaited. Currently, a mumber of hematopoietic growth factors with thrombopoietic activity have been identified. This review discusses the biological characteristics and the clinical trial investigation development of platelet growth factors.

Objective To assess the characteristics of heart rate turbulencer (HRT) in elderly patients with decreased left ventricular diastolie function.Methods 40 patients were divided into two groups:20 patients with enlarged left atrium and 20 patients without enlarged left atrium.20 healthy people were selected as controls. Turbu1ence onset (TO) and turbulence slope (TS) were measured,and correlation was analyzed between TO,TS and the E/A,index of Macruz and heart rate variability (HRV).Results TO was higher (P<0.05) and TS was lower in patients (P<0.01),TO was higber in patients with enlarged left atrium than in with out enlarged lef atrium people (P<0.05) and TS was lower (P<0.01).TO was positively (P<0.01) and TS Was negatively (P<0.05),correlated with the index of Macruz.TO Was negatively (P<0.05) and TS was positively (P<0.05) related to SDNN and SDANN.Conclusion HRT can be used as a potential risk predictor in decreased left ventricular diastolic function patients.

Both molecular weight 6000 and 1000 polyethylene glycol (PEG) have been used to induce thc fusion of hepatoma cell by two methods of centrifugation and stillstand. The results showed that 50% PEG of molecular weight 1000 and centrifugation increase the percentage of fused cells. The procedure of cell fusion has been examined. The cytoplasm has been fused when the cells start fusing in one hour and a half, and the neucleus start fusing in two horus and a half.

Objective To analyze the efficiency of mifepristone combined with norethindrone in treating dysfunctional uterine bleeding of peri-menopause. Methods 56 patients with dysfunctional uterine bleeding of peri-menopause were randomly divided into two groups, the study group(30 cases) and the comparision group(26 cases). The patients in the study group were treated with mifepristone in small doses combined with norethindrone. And the patients in the comparision group were treated only with norethindrone. Before treating, all the patients were observed and measured symptom of dysfunctional uterine bleeding, blood routine,the function of liver and ren.the en-dometrial thickness and pelvic by ultrasonography. Through hysteroscopy or uterine curettage of diagnosis, en-dometriums were measured by pathology. Results 26 cases in the study group were evaluated as effective,2 cases as obviously effective,and 2 cases as no effective. In the comparision group, 10 patients were evalutated as effective,8 patients as obviously effective,8 patients as no effective. The total effective rates of study group was significantly higher than those of comparison group(P

OBJECTIVE: To establish a method for the determination of nitrofurazone in nitrofurazone and zinc oxide liniment. METHODS: The content of nitrofurazone was determined by UV spectrophotometry. The solvent was water and the wavelength was 375nm. RESULTS: There was good linear relationship within the concentration range of 1.05～12.60?g?mL-1(r=0.999 8). The average recovery was 100.9%,RSD=0.07%. CONCLUSION: The method was sensitive, accurate, reliable, reproducible, and suitable for quality control of nitrofurazone in nitrofurazone and zinc oxide liniment.

Traditional concept has been that hematopoietic stem cells (HSC) are tissue-specific stem cells, which are restricted to generate the cell types of the blood and immune system. However, recent studies have shown that there is a higher plasticity of the HSC than previous expected, it can be induced to transdifferentiated into mature cells of other nonhematopoietic organs after transplantation in vivo. In this article, the recent advances in the plasticity of HSC and its potential clinical application are reviewed.

AIM: To study the expression and change of growth hormone receptors in experimental cirrhotic liver in rats. METHODS: Thioacetamide-induced liver cirrhosis was developed in Sprague-Dawley rats. The expression of growth hormone receptor and its mRNA was investigated by radio-ligand binding assay, revere transcript-polymerase chain reaction (RT-PCR) and digital image analysis in liver tissue or hepatocytes taken from normal control or cirrhotic rats with different stages of cirrhosis. RESULTS: Growth hormone-specific singular binding sties, namely growth hormone receptors, were detected in liver tissue or hepatocytes from rat samples with cirrhosis. The binding capacity of growth hormone receptors in rat cirrhotic live tissue was significant lower than that in normal control, and it decreased gradually along with the accumulation of collagen in the process of formation and development of liver cirrhosis. The binding sites of growth hormone receptors in rat cirrhotic liver cells were significantly lower than that in normal control. The expression of growth hormone receptor mRNA in rat cirrhotic liver tissue was also significant lower than that in normal control. CONCLUSIONS: The growth hormone receptor was expressed in cirrhotic livers at a reduced level in isolated hepatocytes or live tissue of cirrhotic rats, and lesser expression of growth hormone receptors was found in later stage of cirrhosis. The suppressed expression of growth hormone receptor was partly due to the reduced expression of its mRNA in cirrhotic liver tissue.
