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。

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.

用正交设计法选择锻淬磁石的最佳工艺

磁石为天然磁铁矿石,质地坚硬,这种矿物药在调配处方前须经过炮制才能使质地酥脆而易煎出有效成分。常用的方法为火煅醋淬。历代文献记载要反复煅淬,操作起来较麻烦,费时费功。磁石究竟在多大温度下煅烧?煅烧几次?醋淬几次?目前淌未见报。下面我采用正交设计法,
