It has been thought that the complicated gene-gene interaction, heterogeneity of clinical presentation and numerous farraginous experimental data make it more difficult to draw a firm conclusion with genetic research work.

这主要是因为精神分裂症临床分型复杂，症状多样，若将不同类型的患者混杂起来研究将难以对这种异质性疾病作出可信的结论；同时该病作为多基因病的一种，其发病是由许多微效基因共同作用决定的，若孤立地研究某个候选基因或候选染色体区域与疾病的关系，也难以得出满意的结果；而且在研究结果的分析中，某个基因对发病的微小贡献将被&淹没&在巨大的数据信息中，难以提取。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

Not only it impairs patients" genital health and Quality of life, but also is associated with an increased risk of type 2 diabetes, endometrial carcinoma, hyperlipemia, hyperpiesia, cardiovascular and cerebrovascular events. Up to now, precise pathogenesy of PCOS is yet unknown. The modern medicine indicates the etiopathogenisis of PCOS related to hereditism, endocrinology, immunology, metabolism and so on. The main features are hyperandrogenism and hyperinsulinemia, the correlation and between the above factors and how they inference PCOS are still unclear. In the view point of Traditional Chinese Medicine ,PCOS classifies to "menopathy","infertility" and "Zhengjia , its occurrence exists a close relationship with dysfunction of liver, kidney, spleen and further inducing deficiency, sputum, sluggish stagnant and fire. Many scholars insist that pathogenesis of PCOS is a renal deficiency plus phlegmatic hygrosis. However, after many years clinical observation.

随着研究的不断深入，PCOS日益显示出其复杂性和重要性；他不仅影响到患者的生殖健康及生存质量，而且其异常的激素环境使该类患者对子宫内膜癌、高血压、高血脂及心脑血管意外等病发生危险明显增加；但目前该病的确切发病机制尚不十分清楚，现代医学认为其病因涉及到遗传、内分泌、免疫、代谢等多个方面，以高雄激素血症与高胰岛素血症为主要特征，二者在PCOS发病中的确切作用，目前尚不清楚；PCOS相当于祖国医学的&月经病&&不孕&&癥瘕&等范畴，本病的发生与肝、肾、脾功能失调导致虚、痰、瘀、火有关。
