HCMV infection aggravated bile duct damage, obliterative arteriopathy and fibrosis in chronic liver rejection, the pathogenesis of which were correlated with early increased mRNA expression of TGF-β,PDGF, bFGF after HCMV infection.

HCMV感染能加剧慢性排斥反应中的病变，即增加胆管损伤、泡沫细胞阻塞性动脉病变和受体肝脏纤维化的程度；其致病机制与HCMV感染后增加TGF-β，PDGF 和bFGF的早期表达相关。

Barnyard grass, Echinochloa crus-galli, is one of the notorious weeds worldwide. To explore the potential of Alternaria augustiovoidea strain AAEC05-3 as mycoherbicide to control barnyard grass, the effect of inoculum potential and spray volume on the pathogenicity of strain AAEC05-3 to barnyard grass and host specificity of strain were studied using pot experiment.

为了确定稗草生防菌狭卵链格孢Alternaria augustiovoidea菌株AAEC05-3防除稗草的潜力，研究了其孢子接种浓度和喷液量对该菌株致病力的影响及菌株的寄主专化性。

There were few studies on the causative gene of PCOS in our country. We chose the candidate gene associated with androgen receptor gene to study, considering the endocrinal characteristics such as hyperandrogenism.

本课题针对PCOS常见的高雄激素血症的内分泌特征，选择雄激素受体基因进行研究，旨在探讨AR基因微卫星CAG多态性与PCOS发病及临床特征的关系，寻找PCOS的致病基因，以期为PCOS的预防和治疗提供理论基础。

Objective To detect Mycoplasma genitalium infection in high risk populations of STDs from six cities in China and try to clarify the possible role of Mg in the pathogenesis of non? gonococcal urethritis.

目的 对我国部分地区不同类型的性病人群进行生殖支原体感染状况检测分析，以明确Mg感染在非淋菌性尿道炎中的可能致病作用。

Our corporation since establishment consistently adheres to natural materials and does the research and development of safe and healthy products. Japanese cedar and hinoki cypress which are indigenous to Japan become fire resistant and do not produce toxic gas even when set fire once they are treated with our ecologically friendly product called 'Super FX3200'.

本公司自成立以来一直致力于安全、健康产品的研究，自主开发的以天然材料成分为主的耐热粘合剂和粘合性耐热涂层剂产品---&超级FX3200系列&和用该产品处理的日本柏日本杉板材，具备耐火性而不会燃烧、不会冒烟、不会释放有毒气体，是对人友好、让人感到放心、安全、满意的产品，在甲醛等化学物质引发的致病建筑综合症不断地危害人们健康的今天，越来越受到人们的关注和青睐。

Histiocytic necrotizing lymphadenopathy ,, Cutaneous lupus erythematosus

我们於此对菊池氏病与皮肤红斑性狼疮二者间可能的致病关联性作一探讨。

3Genetic factors play a major role inthe control of immune regulation,such as the expression of cytokines.An analysisof TNF〓 gene polymorphism in IgAN and HSP nephritis is beneficial to better un-derstanding of immunogenetic abnormalities in these diseases.But further inves-tigation on a large scale is necessary in order to find out the susceptibility genes orthe markers for a closely-linked susceptibility locus.

某些免疫相关基因是细胞因子表达、调控的决定因素，本实验通过〓基因多态性分析对部分肾小球疾病的遗传背景进行了有益的探索性研究，但是要最终找到致病基因或者连锁遗传标志，尚有待进一步的大规模研究。

Stylosa, but the pathogenicity of P II -3 was stronger than that of P I -1. The host range of P I -1 and P II -3 were the same. Their hosts were special to a certain extent. Only some species of mangrove such as Kandelia candel and Sonneratia apetala could be infected.

结果表明，菌株 P I -1和 P II -3均能引起红海榄赤斑病发生，但菌株 P II -3致病力比 P I -1的稍强；二者的寄主范围一致，均具有一定的寄主专化性，只能侵染部分红树植物如秋茄和无瓣海桑。
