Methods By real-time PCR, the damages of exon 5 and 8 of p53 gene were probed in 37 workers exposed highly to, 16 manager and logistic employees exposed less to an arsenic mill in Yunnan province, and also 25 local people who did not contact with any white arsenic in near past time. At the same time, the urinary total and organic arsenic of workers were detected.

选择云南某砒霜厂－线工人37例、管理和后勤人员16例和当地近期无毒物接触人员25例为研究对象，应用实时荧光定量PCR检测人群p53基因第5和第8外显子损伤，同时检测尿中总砷和有机砷含量，评价人群对砷的代谢转化与p53基因损伤的相关性。

It is correlated about the peak value of spurt urine of metanephric and renal function. It is can be assessment whether renal function has been damaged and degree of injury.

输尿管喷尿的峰值指标与肾功能密切相关，通过观测输尿管喷尿情况，可判定肾功能有无损伤及损伤程度。

The human cartilages are composed of chondrocyte and extracellular matrix,the form of chondrocytes are hypertrophy and the quantity are less;the ECM of cartilage are compised of type II collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury,the ommilayer injury ofcartilage can be recovered by marrow,but because of without stimulation mechanism,the new tissues are merely fibrocartilages,they can not be coincide with hyaline cartilage in menchanics;the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation,thus,the plerosis of articular catilage can not depend on the proliferation of local chondrocyte.Ever since,people tried their best to find a way to reconstruct articular cartilage.

造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

In group E, which had just experienced 30-minute cold storage without rewarm ischemia, hepatic function could well be recovered in a short time during reperfusion. On the contrary, in group F、G and H, which had experienced rewarm ischemia for 15, 30 and 60 minutes respectively following 30-minute cold storage, hepatic function suffered the more severe damage with the more prolonged rewarm ischemia during reperfusion.

在对供肝复温缺血-再灌注损伤的研究中发现，供肝于再灌注期间，仅低温保存30分钟而无复温缺血的E组供肝功能于短时间内即可得到很好的恢复，但低温保存30分钟后又分别经历15、30、60分钟复温缺血的F、G、H三组供肝，其肝脏功能却遭到了明显的损伤，且复温缺血时间越长者，损伤程度越重。
