Objective To evaluate the effect of vascular endothelial growth factor (VEGF) expression on varicose recurrence in esophagus after devascularization in portal hypertensive rats. Methods Murine pre-hepatic portal hypertension (PHPH) was induced by partial portal vein stenosis. 3 weeks after the establishment of the PHPH, all rats including sham operation group (SO) underwent devascularization. Esophagus was sampled at the time of 1, 3, 5, 7, 14, 30, 90 days after devascularization respectively. The expression of VEGF and factor Ⅷ related antigen (FⅧAg) was detected by immunohistochemistry,and the microvessel density (MVD) was counted under FⅧAg staining. ResultsCompared to the SO rats, the MVD of esophagus in PHPH rats increased significantly before devascularization(P0.05). At the third month after devascularization, the MVD of PHPH rats was higher than that of SO rats. In SO rats, MVD increased after devascularization, reaching the peak on the third day and then levelling off.The expression of VEGF before devascularization in PHPH rats was significantly higher than in SO rats, and VEGF experssion was on the pinnacle in two groups after devascularization, but the expression time of PHPH rats was significantly longer than SO rats(P

Objective To analyze the correlative factors and cause of death within short-term in initially lucid patients with intracerebral hemorrhage (ICH).Methods 441 patients with spontaneous ICH admitted within 24 hours of onset and with Glasgow Coma Scale (GCS) score more than 9 on admission were enrolled. The demographic characteristics, clinical features at onset, CT, electrocardiograph (ECG) and laboratory findings, medical complications and 27 days outcome were recorded. Univariate and multivariate analysis were performed.Results 24 (5.4%) patients died winthin 27 days after onset, 14 (58.3%) died of brain herniation and central respiratory failure, another 10 (41.7%) of systemic complications. Multivariate analysis demonstrated that age was 75 years old or more, urinary incontinence at onset, peripheral white blood cell count more than 10.0?10 9/L on admission, blood glucose more than 7.0 mmol/L and abnormal ECG were independent correlative factors of death.Conclusions The short-term outcome of initially lucid patients with ICH is favorable in general, albeit with a relatively low mortality. Brain herniation and central respiratory failure were main cause of death, and they have independent correlative risk factors.

BACKGROUND: Chinese herbs of common yam rhizome, balsampear fruit and bagasse fiber have good effects on decreasing blood glucose and lipid, but its mechanism is unclear.OBJECTIVE: To observe the effect of compound preparation of common yam rhizome and balsampear fruit on blood glucose, lipid, blood insulin and anti-infection of rats with type 2 diabetes mellitus (DM).DESIGN: Randomized controlled animal study.SETTING: Technological Developing Center, Pharmacological Department, Experimental Animal Center, and Central Laboratory of Guangdong Medical College.MATERIALS: A total of 80 female SD rats with 4 months old and of SPF grade were selected in this study. Flumamine (Jilin Dongbeiya Pharmaceutical Co., Ltd., batch number: 040126); total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and triacylglycerol (TG) (Beijing Zhongsheng Biotechnological Co. Ltd.); Surestep Life scan blood glucose meter and test paper (Johnson Company, USA); insulin radio-immunity kit (Shanghai Navy Medical Institute); UV-3010 ultraviolet spectrophotometer (Japan Shimadzu); compound preparation of common yam rhizome and balsampear fruit (Technological Developing Center of Guangdong Medical College, batch number: 040321); suspension was extracted from common yam rhizome, balsampear fruit and dietary fiber of bagasse through water with 1 kg/L raw materials.METHODS: Animal breeding and samples collecting were carried out in the Experimental Animal Center and Technological Developing Central Laboratory of Guangdong Medical College from June 2004 to December 2005; meanwhile, detection of marker was carried out in the Pharmacological Department and Central Laboratory of Guangdong Medical College. ①Twenty rats were randomly selected as normal control group and perfused with 5 mL/kg saline every day. Other 60 rats were perfused with 5 mL/kg fat emulsion once a day for 4 weeks, and then, rats were fasted for 12hours and peritoneally injected with 2 g/L streptozotocin (30 mg/kg). Rats in normal control group were peritoneally injected with the same volume of citromalic acid buffer. Three days later, blood glucose was measured ranomly and measured again after 2 weeks. If level of blood glucose was igher than 13.5 mmol/L or urinal glucose was ＞ ++ for two weeks, the models were successful (n=48). ② According to random lot method, 48 rats were divided into three groups: model group, flumamine group and comound preparation group with 16 in each group. Rats in model group were perfused with 5 mL/kg fat emulsion; moreover, rats in flumamine groupr and compound preparation group were perfused with 5 mL/kg fat emulsion and then with 1 mg/kg flumamine and 5 mL/kg compound preparation including 1 kg/L raw drug, respectively. Rats in normal control group were perfused with 5 mL/kg saline. All rats in each group were perfused once a day for 6 weeks in total. ③ Value of blood glucose was measured at one day before the experiment finished. Twelve hours after fasting, level of plasma insulin was measured with radio-immunity method; levels of plasma total protein and albumin were measured with spectrophotography; levels of TG, TC and HDL-C were measured with the related kits. ④ Measurement data were compared with analysis of variance (ANOVA). Levene's test was firstly used to evaluate regularity of variance. Bonferroni test was used for regular variance; however, Tamhane's T2 was used.MAIN OUTCOME MEASURES: Effect of compound preparation on levels of blood glucose, insulin, lipid and plasma protein of rats with type 2 DM.RESULTS: Twelve rats were lost because of failure in modeling, and 4rats in model group and 2 in flumamine group died during the experiment,respectively. Therefore, 62 rats were involved in the final analysis. ①Measurement of fasting blood glucose and plasma insulin: Value of fasting blood glucose in normal control group was lower than that in other three groups (t=2.673-4.224, P ＜ 0.05-0.01), but level of plasma insulin was higher than that in other three groups (t=3.780-5.824, P ＜ 0.05-0.01).Fasting insulin in model group was lower than that in compound prepara tion group (t=2.825, P ＜ 0.05); fasting blood glucose was higher than that in flumamine group and compound preparation group (t=3.906, 3.056, P ＜ 0.05); * level of insulin in flumamine group was lower than that in compound preparation group (t=3.014, P ＜ 0.05); level of fasting blood glucose in flumamine group was close to that in compound preparation group (P ＞ 0.05). ② Measurement of lipid: Levels of TC and TG in normal control group were lower than those in other three groups, but level of HDL-C was higher than that in other three groups (t=2.521-4.892, P ＜ 0.05-0.01).Plasma TC in model group was higher than that in flumamine group and compound preparation group (t=2.466-2.512, P ＜ 0.05), value of TG was higher than that in compound preparation group (t=2.612, P ＜ 0.05), and level of HDL-C was lower than that in compound preparation group (t =3.688, P ＜ 0.05). Plasma TG in flumamine group was higher than that in compound preparation group (t=2.620, P ＜ 0.05). ③ Measurement of plasma protein: Levels of plasma total protein were close to each other (P ＞ 0.05). Plasma albumin in normal control group was higher than that in model group and flumamine group (t=3.773, 3.104, P ＜ 0.05), but that was close to that in compound preparation group (P ＞ 0.05). Ratio between albumin and globulin in normal oln that in other groups (t=2.830-3.056, P ＜ 0.05). Level of plasma albumin and ratio between albumin and globulin were lower in model group than those in compound preparation group (t=2.604, 3.808, P ＜ 0.05).CONCLUSION: Compound preparation can decrease levels of blood glucose and lipid, increase content of insulin, and improve anti-infection ability of rats with type 2 DM.

ObjectiveTo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transrectal prostatic biopsy (TPB) who had sterile preoperative urine.MethodsMEDLINE, EMBASE, Cochrane Collaboration Reviews, Chinese Medical Current Contents (CMCC), and National Knowledge Infrastructure (CNKI) were searched for rando-mized controlled trials that compared the effect of antibiotic prophylaxis with placebo or active controls for men undergoing TPB with preoperative sterile urine. Two reviewers independently extracted the data of patient characteristics and outcomes based on a prospectively developed protocol.ResultsA total of 12 trials (3 placebo controlled, 3 non-treatment controlled, and 6 activly controlled) involving 1 987 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing TPB significantly decreased bacteriuria and middle degree fever incidence, but could not decrease the incidence of bacteremia. The relative risk for post-TPB bacteriuria, middle degree fever, and bacteremia were 0.32 (95% CI 0.23 to 0.46), 0.37 (95% CI 0.17 to 0.77), and 0.96 (95% CI 0.61 to 1.50), respectively. Effective antibiotic classes included quinolone, co-quinolone and nitroimidazole, and co-trimethoprim and sulfamethoxazole. Treatment protocols of any duration were effective.ConclusionAntibiotic prophylaxis obviously decreases the incidence of bacteriuria and middle degree fever but not bacteremia in men with preoperative sterile urine undergoing TPB. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and co-quinolone and nitroimidazole. Treatment protocols of any duration are effective with no heterogeneity.
