质子重离子治疗室温湿度高精度控制
上海市质子重离子医院的核心设备是质子重离子系统(简称“PT”)设备,为了保障PT设备正常运行,确保患者治疗安全性和精确性,设备厂商对PT设备相配套的HVAC(采暖通风与空调)系统提出了较高技术要求,即质子重离子治疗区域温湿度偏差必须在一定范围内.为此,医院后勤保障部门开展了一系列保障工作,并对HVAC系统进行了改造.

超高压提取技术在中药提取中的应用
超高压(UHP)的全称是"超高冷等静压(ultra highisostatic hydrostatic pressure at room temperature,UHIHP)",简称为冷等静压(cold isostatic high pressure,CIHP).据目前科学技术发展的状况和液压技术的特点可将超高压定义为100 MPa以上的压力[1].

室温放置时间对血凝四项检测结果的影响
PT、APTT、TT及Fib的检测被广泛用于出血性疾病的辅助诊断、口服抗凝药的治疗监测及术前凝血功能的评估等.血凝检测具有其特殊性,即不是分析某种特定的物质,而是对一系列酶促反应终点时间的测定,因此其影响因素也就更为复杂,包括标本的采集、运输、离心、保存及检测方法等.

ZMW型环氧乙烷灭菌箱对异体骨材料灭菌效果的初步观察
Background: The foreign bone material of the same species was widely applied, while for the multiple manipulating processes, it got lots of chances to be infected, especially for the bone manufacturing, the pollution odds increased greatly, so the sterilizing process was most important. Objective: To observe the sterilizing effects of ZMW anprolene case on foreign bone materials to find a safe and economic disinfecting way. Unit:First attached hospital of the Shihezi medical university. Subject:The manipulating method of the foreign bone material of the same species: In clean environment., bone was got in 2 hours after death of the donor, soft tissue was removed and it was made to foreign bone material of 0.5 cm× 0.5 cm× 2 cm, it was washed with water and marinated till the water got clear, then washed with distilled water repeatedly, lipid was removed with 1:1 chloroform and methanol for 4 hours at room temperature, calcium was removed with 0.6 mol/L HCL for 4 hours at 4 ℃ , it was washed with distilled water till the pH was 6.5. The bone material after treating were divided into two groups, one was dried in common air dried to make wet one plantation material and the other one was dried in 37℃ roasting case to make dry bone plantation material. They were both put in double polyethylene bags and sealed with standard sealing machine, the weight was 5 g,
