A Bacteriocin-producing Lactic Acid Bacteria R260 strain was screened from plant-material. The morphological, physiological and biochemical features of R260 strain were as follows, the bacterial cell was gram-positive, straight rot-shaped, single or pairs and the spor wasn't found. VP reaction, nitrate reaction, gelatin liquefy and catalase reaction were negative. Glucose, fructose, sucrose and maltose were fermented to organic acids.

本实验从植物性材料中筛选到一株产细菌素的菌株 R260，菌株的形态观察和生理生化性质测定结果显示，菌体细胞呈杆状，单个或成对出现，革兰氏阳性，无芽孢；接触酶反应、硝酸盐还原实验、明胶液化实验、产氨实验、水解淀粉实验、硫化氢产生实验和 VP 实验均为阴性；发酵葡萄糖、蔗糖、麦芽糖、果糖和核糖。

Of the 126 exacerbation sputa, all samples were negative for M. pneumoniae and C. pneumoniae DNA, whereas one sample was positive for Legionella non-pneumophila DNA.

所有126例急性加剧患者痰液样本中检测肺炎支原体和衣原体的DNA结果为阴性，一例样本检测非肺炎的军团杆菌属DNA结果为阳性。

Of the 122 stable state sputa, all samples were negative for M. pneumoniae and C. pneumoniae DNA, whereas one sample was positive for Legionella non-pneumophila DNA.

所有122份稳定慢性阻塞性肺疾病患者痰液样本中检测肺炎支原体和衣原体的DNA结果为阴性，但有一例样本检测非肺炎的军团杆菌属DNA结果为阳性。

AFA was correlated to other autoantibodies of RA. Immunoblotting detecting of AFA, a simple and standardizable test, may be an alternative or complement to conventional detection of RF, APF, anti-CCP and AKA, suit to apply in clinic.

结论AFA 可视为RA 的特异性血清学标记，尤其对RF 阴性以及早期RA 诊断很有帮助；AFA 与其它RA 相关自身抗体相关，他们联合检测可以相互补充，提高对RA 的诊断价值； AFA 检测方法简单可靠，适合在临床上应用推广。

RESULTS The expression of MCP-1 was negative or very weak in cells of subretinal fluid from RD.

结果视网膜下液中细胞成份MCP-1的表达均为阴性或弱阳性，B级PVR手术集取物以及增殖膜中，MCP-1表达阳性程度随PVR等级的升高而逐渐增高。

OBJECTIVE To investigate qacE-sull gene resistant to the quaternary ammonium compounds and sulphonamide compounds in Gram negative bacteria in order to provide the information of bacterial resistance to disinfectants.

目的检测革兰阴性菌中耐季铵盐消毒剂-磺胺复合物的qacE-sul1基因，为临床提供细菌对消毒剂的耐药信息。

Objective: To investigate qacE-sul1 gene of resistant to the Quaternary Ammonium Compounds and Sulphonamide Compounds in Gram negative bacterium in order to provide the information of bacterial resistance to disinfectants.

目的：检测革兰阴性菌中耐季铵盐消毒剂-磺胺复合物的qacE-sul1基因，为临床提供细菌对消毒剂的耐药信息。

Toxicologic screening on admission to the hospital was negatie for alcohol and for controlled substances.

入院时进行的有关酒精和其他受控毒性物质的毒理学检查，结果均为阴性。

Animals in each group growth were good. No abnormal phenomenon was observed. ConclusionThe Trollius Beverrage's MTD of mice and rats was greater than 20000mg/. It was concluded that the product had no toxicity. The result of mutagenic test was negative and no abnormal phenomenon was observed after feeding for 30 days.

结论金莲花露对两种性别的大、小鼠的MTD均大于20 000 mg/，说明该产品属实际无毒物；三项致突变实验结果阴性；大鼠30 d喂养实验各项指标均无明显异常。
