致病

Most infectious diseases are multifactorial and polygenic events with microbial, environmental and genetic components.

目前普遍认为，绝大多数感染性疾病都属于典型的多基因疾病，是致病微生物和宿主之间在长期的进化过程中交互作用的结果。

Objective To analyze the clinical features of pneumomediastinum complicated in polymyositis and dermatomyositis and to study the pathogenesis thereof.

目的研究多发性肌炎／皮肌炎并发纵隔气肿的临床特点，探讨其发病危险因素及致病机制。

For example, in the third quarter of 2007 intel expects to bring the fraction of polynuclear processors in its assortment to 80%.

例如2007年第三季度英特尔预计将分数多核处理器在其致病的80%。

Positive and Negative Syndrome Scale , Global Assessment of Function Scale , Modified Overt Aggression Scale , Premorbid Schizoid and Schizotypal Trait and Premorbid Social Adjustment were used in assessment of various phenotypes in affected siblings. It was found that there were high similarities of these phenotypes in siblings with schizophrenia. The results suggested that common etiology, whether genetic or environmental factors, might existed in this pattern of family.

本研究采用阳性症状和阴性症状评定量表、功能全面评定量表、外显攻击行为量表、病前社会适应和病前分裂样分裂型特质对同胞患者进行评定，结果显示各种表现型具有较好的一致性，说明同胞对患者间具有相同的遗传、环境性家族致病因素。

Through a relaxed selection of 10 passages, the precocious line showed genetically stable in its prepatent time, OPG, and as well as its pathogenicity.

对选育的早熟系进行放松选择传代10次，其潜隐期、OPG、致病性均保持了早熟系的特征。

In 109 individuals of 19 WD families, we found 8 presymptomatic patients, 10 carriers and 15 normal people, 3 could not be determined. The rate of gene diagnosis was 91.67%.

共检出8例症状前患者，10例致病基因携带者及15例正常人，3例未能确定，基因诊断率达91.67%。

the low procreant routeway infection is one important reason to abortion in prevalence.through enhance pertinence treatment to microbe which can cause disease,it might reduce the quotiety of abortion in prevalence.

孕期下生殖道感染是引起孕妇早产的一个重要原因，加强对其中一些高致病性微生物针对性的治疗，可能对减少早产的发生起到重要作用。

Methodological principles of complexity science and research thoughts of pulse examination ;2. Pulse examination could prognose the disease as well.

通过总结脉诊的临床功能，认为脉诊在诊治临床躯体性疾病中，可以辨识体质、致病因素、中医病机、西医疾病及对所患疾病具有预测功能。

Objective This study was designed to investigate the different status of provirus HIV DNA in non-progressor and progressor of HIV-1 infected persons.Methods HIV RNA, HIV DNA were detected with long-distance PCR,reverse-transcription PCR,Southern blot and molecular hybridization from plasma and peripheral blood mononuclear cells, using primers locating between long terminal repeats LTR(U5)-LTR and so on.

HIV是一种变异非常活跃的病毒，这种变异既有可能医疗增强病毒在宿主体内的适应性和生存，又有可能医疗使病毒复制受到阻碍，影响病毒在宿主体内的生存，为了更进一步掌握HIV变异规律，阐明HIV致病机理，我们用逆转录PCR、长片段PCR、Southern转印、分子杂交等对HIV感染无进展者和进展者HIV RNA、CD4细胞、HIV DNA及存在状态进行了研究。
