Conclusions\ Enhancing ICU administration in every aspect and infection surveillance, strict aseptic technique and sterilization-Isolation technique, using semisupine position, reducing unnecessary suctioning and nebulization. Avoiding the risk factors which associated with pulmonary infection was the effective method to reduce the pulmonary infection.

加强ICU全方位管理和感染监测，严格无菌技术和消毒隔离，尽量采用半卧位，减少不必要的吸痰和雾化吸入，避免肺部感染的危险因素是降低肺部感染行之有效的措施

On the other hand, a higher frequency of CCR-64I allele was also observed in HIV-1 uninfected individuals who were heterosexually exposed to HIV-positive index partners (p=0.164), but most of the reports didn't support this result.

在异性传播病例中，有暴露史而未感染病毒者CCR2-64I的基因频率明显高于感染者，说明CCR2-64I对异性传播有一定的保护作用，不过与以往的研究不一致。多数研究认为，CCR2-64I对HIV-1异性传播无明显保护作用，有研究甚至认为是一种危险因素。
