4种病原菌特异基因片段阳性蜱的16S rRNA基因克隆文库分析

Objective To develop the method of 16S rRNA gene clone library for tick bacterial flora analysis, and to analyze the detection effective of pathogens in tick and capacity of bacterial flora diversity. Methods Primers were designed according to the specific gene of Borrelia burgdorferi, Bartonella henselae, Anaplasma phagocytophilum, Ehrlichia chaffeensis and templates were choosen by positive PCR result to amplify the DNA extracted from the ticks. One set of primers targeting 16S rRNA gene conserved region were chosen to amplify certain fragments, DNA extraction, PCR reaction, cloning and sequencing. Nucleotide sequences were compared with GenBank database. Calculated Coverage values of clone library and Shannon-Wiener diversity index. Results Sixteen defined genus-or species-bacteria were detected in 103 valid sequences. Eight species were edge type (Clone No. > 5). Three kinds of pathogens were identified (Borrelia burgdorferi, Bartonella henselae and Rickettsia sp). Three kinds of pathogens were not edge type(Clone No. < 5). Coverage value was 96.11%, and Shannon-Wiener index was 2.40. Analysis results of cloning sequence showed that tick-parasitic bacteria mainly were α and γ deformation mycetes which accounted for 56.25% (9/16). Conclusions The 16S rRNA gene sequences technology could make relative quantitative of bacterial flora, and detect many kinds of pathogens in tick. It's a good method for detection of pathogens and bacterial flora analysis.

复合二氧化氯消毒饮用水副产物含量分析

目的了解复合二氧化氯消毒饮用水产生的副产物含量及其影响因素,探讨饮用水中消毒副产物含量变化规律。方法对2008-2013年复合二氧化氯消毒的出厂水和管网末梢水的亚氯酸盐、氯酸盐、三氯甲烷等指标进行检测分析。结果出厂水和管网末梢水的各项检测指标合格率以及各消毒副产物的均值差异均无统计学意义(P值均0.05);二氧化氯、耗氧量与消毒饮用水产生的副产物亚氯酸盐含量相关。结论复合二氧化氯消毒饮用水避免了有机副产物三卤甲烷污染的卫生问题,但还需提高二氧化氯转化率,并优化投加方式。

依达拉奉对肝脏缺血再灌注损伤保护作用的临床研究

目的观察依达拉奉对肝切除术患者肝缺血再灌注损伤的保护作用。方法82例肝切除患者,随机分为对照组（n=40）和试验组（n=42）,试验组给予依达拉奉。分别于术前及术后测定中性粒细胞（PMN）计数、血清谷丙转氨酶（ALT）、谷草转氨酶（AST）含量及肝组织中丙二醛（MDA）及超氧化物岐化酶（SOD）活件。结果肝脏缺血再灌注损伤后,对照组的ALT、AST水平及MDA含量明显高于试验组（P〈0．01或P〈0．05）,SOD活性及PMN计数明显下降（P〈0．05）。结论依达拉奉对肝脏的缺血再灌注损伤有显著的保护作用,其机制可能与减少PMN在肝脏内的聚集进而调节肝组织氧化与抗氧化平衡有关。
