人血浆高敏感性C反应蛋白与代谢综合征相关性分析

目的:了解我国人群血浆高敏感性C反应蛋白(hs-CRP)水平与代谢综合征(MS)关系及其它影响hs-CRP水平的相关因素。方法:1198例血浆标本来自2006年3月~2006年11月在浙江省桐乡市第三人民医院体检人群。采用Beckm an LX20血生化全自动生化仪及其配套试剂,测定上述空腹血浆标本中血糖(FPG)、甘油三脂(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c)和hs-CRP水平。MS诊断标准参照中华医学会推荐标准。采用SPSS13.0统计学软件,分析hs-CRP水平与MS关系及其它影响hs-CRP水平的相关因素。结果:男性hs-CRP水平(x±s=1.55±0.53)高于女性(x±s=1.32±0.56)(P<0.001)。15.3%被检者(183/1198)患有MS,其hs-CRP水平明显高于非MS者(P<0.001)。各MS判断指标中,分别有肥胖、高血压病、糖尿病、高TG、低HDL-c时,其hs-CRP水平也明显升高(P<0.001)。排除年龄、性别影响后,hs-CRP水平与MS显著相关(OR值2.18,P<0.001)。结论:hs-CRP水平与MS密切相关,hs-CRP水平增高可作为独立反映MS发生的标志性检测指标。     

EFFECTS OF A SYNTHESIZED PHOSPHODIESTERASE INHIBITOR, ZSY-27, ON PANCREATIC EXOCRINE SECRETION OF THE DOG

The effects of a synthesized phosphodiesterase inhibitor, ZSY-27, on the secretion of pancreatic juice were investigated in dog isolated and blood-perfused pancreas, and compared with those of secretin and dopamine. Intravenous administration of ZSY-27 (0.3-1 mg/kg) elicited increases in pancreatic secretion. Intra-arterial (i.a.) administration of ZSY-27 (0.1-1 mg) also elicited increased secretion. The secretory activity of ZSY-27 (1 mg) was approximately equal to that of 0.1 units of secretin and 2.5 micrograms of dopamine. The concentration of bicarbonate in the pancreatic juice induced by ZSY-27 i.a. was increased, but the protein concentration was not increased significantly. These effects are analogous to those of secretin and dopamine. ZSY-27-induced pancreatic secretion was not modified by pretreatment with phentolamine, propranolol, atropine, sulpiride and cimetidine. Secretin-induced secretion was significantly potentiated by infusion of ZSY-27 (25 micrograms/min) but dopamine-induced one was not. These results suggest that ZSY-27 increases pancreatic secretion acting directly on the ductular cells of the dog pancreas, at least in part, through the increase of intracellular cyclic AMP concentration by inhibiting phosphodiesterase activity.     

不同起搏模式对病人生存质量影响的调查研究

[目的]探讨不同起搏模式对病人生存质量（QOL）的影响。[方法]以健康调查问卷（SF一36量表）对112例不同起搏模式病人进行问卷调查，比较3种起搏模式下病人的QOL水平。[结果]除机体疼痛、角色情绪2个维度外其余6个维度（生理功能、角色限制、活力、社会功能、精神健康、总体健康）3种起搏模式间比较差异有统计学意义（P〈0．05）。[结论]应用AAI型、DDD型起搏器的病人生存质量优于VVI型起搏。     

云南罗平医院员工对医院的认同度分析

通过问卷调查和访谈分析,调查了云南罗平医院194名员工对医院的认同度,调查对象包括行政、临床和后勤人员,从医院管理模式、医院绩效考核、医院薪酬待遇等方面用描述统计方法分析了数据,显示了医院员工的认同度情况及管理中存在的问题,并分析了不同因素对医院员工的认同度影响,为进一步改善医院管理状况,提高管理水平提供了参考。     

Synthesis of 3-(3-pyridyl)- and 3-(3-benzo[b]thienyl)-D-alanine

The DL-arylamino acid ethyl ester derivatives of β-(3-pyridyl)-DL-alanine, and β-(3-benzo[b]thienyl)-DL-alanine were synthesized by diethyl acetamidomalonate condensation with the respective arylmethyl halides followed by partial hydrolysis to the monoethyl ester and decarboxylation. Each derivative was enzymatically resolved to a separable mixture of the corresponding N-acetyl-L-amino acid and the unchanged D amino acid derivative. Acidic hydrolysis of the latter gave the corresponding D-amino acid, the optical purity of which was established by HPLC analysis of the 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate (GITC) derivative. The free D amino acids were converted to D-BOC derivatives by reaction with di-tert-butyldicarbonate in tert-butyl alcohol, water and sodium hydroxide.     

自杀基因联合中医药疗法治疗肿瘤的设想

自杀基因疗法是一种具有良好应用前景的肿瘤治疗新措施。但如何有效提高疗效是目前仍须解决的关键性问题。由于免疫机制在自杀基因疗法旁杀伤效应中的重要作用，激活荷瘤机体的免疫功能，改善自杀基因抗肿瘤作用的炎症免疫微环境，是提高肿瘤自杀基因疗法疗效的主要策略。中医中药在调节机体免疫状态方面具有肯定的作用，与其他方法比较具有明显优势。因而，将自杀基因疗法与中医中药联合应用，有可能起到提高肿瘤自杀基因疗法疗效，防止肿瘤复发的作用。提出了自杀基因联合中医药疗法治疗肿瘤的新设想，为肿瘤基因治疗提供了一种新的思路和模式。     

四类抗感染药物不良反应相关因素的探讨与分析

云南省中缅边境地区疟疾血清流行病学调查分析

目的 了解中缅边境一线县、二线县、及一线三个县的一线自然村、二线自然村的疟疾流行情况,为制定边境地区疟疾防治措施提供科学依据。方法 采用IFAT对中缅边境沧源、耿马及孟连一线县与双江县、永德县二线县,边境线3县一线自然村和二线自然村进行疟血清流行病学调查,用电脑软件EPI6X2检验法进行数据分析。结果一线县抗体阳性率23.88％（568/2379）,二线县抗体阳性率1.40％（10/712）,一线县显著高于二线县（x2=180.54;P<0.01）。一线县的一线自然村抗体阳性率33.05％（467/1413）,二线自然村抗体阳性率10.46％（101/966）,一线自然村显著高于二线自然村（x2=159.92;P<0.01）。结论IFAT抗体阳性率和阳性GMRT说明靠近边境地带比远离边境的地带疟疾流行更为严重。应加强出入境人员的防治工作,才能控制边境疟病流行。     

Biochemical and ultrastructural alterations produced by miconazole and econazole in Trypanosoma cruzi

Miconazole and econazole, two fungicide imidazole derivatives, completely inhibited growth of Trypanosoma cruzi (Tulahuen strain) at concentrations of about 20 muM. Culturing of T. cruzi in the presence of lower doses of imidazole derivatives produced: decrease of 5,7-diene sterol content in epimastigotes (including ergosterol); disappearance of the nuclear chromatin, vacuolization and decrease in the electron density of the cytoplasm; selective surface alterations as revealed by an increased response to wheat-germ- and phytohemagglutinin. At variance with the effect of miconazole on Candida (De Nollin et al. (1977) Antimicrobial. Agents Chemother. 11, 500-513), miconazole and econazole, under the experimental conditions used, did not increase the rate of hydrogen peroxide generation by T. cruzi.
