Objective To observe the effects of losartan and amlodipine on blood pressure,plasma levels of leptin,adiponectin and norepinephrine (NE) and insulin sensitivity in obese hypertensive patients.Methods The levels of plasma leptin and adiponectin were determined by RIA and the plasma NE level was assayed by high- performance liquid chromatography.Insulin resistance index (HOMA-IR) was evaluated using the homeostasis model.Results Compared with basal levels,after 16-weeks' therapy,plasma leptin,HOMA-IR and body mass index were significantly decreased in losartan group [(35.6?18.5 vs 32.0?17.1)?g/L,P

Objective:To screen the tumor markers of laryngeal carcinoma and to investigate their expression in preoperative and postoperative serum.Method:The distinct protein in serum was detected in 32 cases of laryngeal carcinoma and 38 healthy people by IMAC-Cu proteinchip array and surface-enhanced laser desorption/ionization time-of-flight mass spectrometry(SELDI-TOF-MS).The distinct proteins in serum were detected in 32 cases of laryngeal carcinoma preoperation and within 10 days 15 cases of laryngeal carcinoma postoperation with the same methods.The discriminatory profiling between preoperative and postoperative patients was analyzed by Biomarker Wizard software and Biomarker Pattern software.Result:The results showed that fifteen differentially expressed proteins in serum were screened by analysis of protemic spectra of preoprative patients and normal subjects.Seventeen kinds of protein differentially expressed in serum were screened by analysis of protemic spectra of preoperative and postoperative patients.Six kinds of protein(2 958.52,3 796.89,5 148.86,6 115.57, 052.18,and7 770.76)were obtained for making up patterns that was able to class the preoperative-team and postoperativeteam.Corresponding correct ratio were 84.38%(27/32)and 73.33%(11/15).Conclusion:The preliminary results suggest that classification system will provide a highly accurate and innovative approach for the arly dioagnosis of laryngeal carcinoma and judgement of prognosis.SELDI-TOF-MS technology is a useful tool for a high throughput screening of large-sized serum samples tO discover potential biomarkers for laryngeal carcinoma.

Aim To investigate the protective effects of Aplysin on ethanol-induced oxidative damage in rat pri-mary hepatocytes. Methods Rat primary hepatocytes were obtained via the portal vein collagenaseⅣin situ perfusion technique followed by a Percoll density gradi-ent centrifuge. MTT test was used to determine the op-timum dose of Aplysin and ethanol, and detect the cell vitality in primary hepatocytes. Supernatants of primary hepatocytes were harvested to measure AST and LDH level, and the SOD, GSH-PX activities and MDA con-tent in primary hepatocytes were observed. Flow cy-tometry was used to detect the cell apoptosis rate. DNA damage in primary hepatocytes was detected by single-cell gel electrophoresis assay. The level of mitochon-drial membrane potential in primary hepatocytes was tested by fluorogenic probe JC-1 . The CYP2 E1 activity in primary hepatocytes was detected by colorimetry. The proteins of CYP2 E1 were detected by Western blot. Results 300 mmol·L-1 dose of ethanol and 30 mg·L-1 dose of Aplysin were the optimal dosages and were used in the subsequent experiments. Hepatocyte vitality was significantly increased in Aplysin group compared to that in ethanol group, and Aplysin inhibi-ted the release of AST and LDH(P<0. 05). For Apl-ysin treatment group, the activities of hepatocyte SOD and GSH were significantly increased, and MDA was markedly lowered as compared with those in ethanol group( P <0. 05 ) . Aplysin could alleviate hepatocyte apoptosis significantly, and hepatocyte DNA damage rates of Ⅱ ~Ⅲ level and Ⅳ level were significantly lowered in Aplysin treatment group as compared with those in ethanol group, and Aplysin had evident im-provement in alcohol induced mitochondria damage of hepatocyte. Primary hepatocyte activities and protein expression of CYP2 E1 were markedly lowered in Aply-sin treatment group as compared with those in ethanol group(P<0. 05). Conclusion Aplysin has protective effects on liver oxidative damage induced by alcohol of primary cultured rat hepatocytes by blocking CYP2 E1 activation, relieving oxidative stress, and sharpening the oxidation resistance ability.

Objective To determine the efficacy of lifestyle interventions in adults with impaired glucose tolerance (IGT).Methods MEDLINE (Pub Med),EMBASE,Science Citation Index (SCI),and Cochrane Database were retrieved for articles about the relations of lifestyle intervention and IGT.Searches were limited to English language publications.The RCTs outcome evaluated in this study included 2 h plasma glucose level and fasting plasma glucose,meta-analysis was carried oat by Stata 11.0 among articles for the inclusion and exclusion criteria.The difference of effects was expressed as standardized mean deviation(SMD).Results A total of 10 RCTs studies met the inclusion criteria.Lifestyle interventions were associated with a decline in 2 h plasma glucose and fasting plasma glucose level (SMD =-0.67,P<0.01 ;SMD =-0.33,P<0.01),but high heterogeneity was identified in this meta-analysis.Conclusion Physical,dietary and both combined interventions can reduce 2-h plasma glucose and fasting plasma glucose levels in adults with impaired glucose tolerance.As high heterogeneity was identified in this meta-analysis,more high quality research is needed.

A modified dye test with microplate was to be established to detect Toxoplasma antibodies with cell-cultured Toxoplasma gondii. Numbers of stained and unstained tachyzoites were estimated in every 100 tachyzoites in each well after dyeing with methylene blue. The dilution with 50% tachyzoites stained was used as final dilution. Better results of the microplate dye test has been received when the concentration of tachyzoites in suspension reaches 109/ml with 1% sodium citrate as accessory factor.
