Objective To enhance the application of WLAN technology in hospital information construction.Methods Solving methods were proposed to the problems in application so as to enhance the awareness of safety.Results By analyzing and solving problems,WLAN was used in hospital more safely.Conclusion The ensurance of wireless network security can impel a safe and positive application of wireless network in the hospital information field as the reasonable development of the existing network.

Inflammation has a critical role in the pathogenesis and progression of cancer.lymphocyte and monocyte play an important role in inflammatory reaction,reflecting body immune status.In recent years,more and more clinical studies have shown that pretreatment of lymphocyte-to-monocyte ratio(LMR)in the patients with malignant tumor may have a certain value in evaluating the prognosis of cancer patients such as nasopharyngeal cancer,esophageal cancer,breast cancer,ovarian cancer,lung cancer,gastric cancer,colorectal cancer,etc.This article reviews the latest research progress on the value of LMR in the evaluation of the prognosis of the patients with malignant tumor.

This paper is to study the feasibility of app ly ing three-layers support structure(Browser/Server OR Client/Middle Tier/Serve r)to NO.1Military Project.By windows2000's terminal technology and distributed characteristics of ORACLE DBMS,C/S structure(Client/Server)can be turned into th ree-layers structure.The all subsystems of NO.1military project can work smooth ly on the terminals,and then the problems when NO.1Military project operated in C/S structure can be solved,such as the vulnerability,low operation speed and l arge maintenance workload.To set three-layers support structure with terminal te chnology windows2000-based can not only save investment and reduce maintenance workload,but also have important significance for database safety.It has a bri lliant application prospect.

Tumor cells,and a variety of stromal cells,immune cells and cytokines constitute a complex tumor microenviron-ment.Among them,tumor-associated macrophages(TAMs)are one of the most important stromal cells in microenvironment and ac-tively participate in tumor growth,invasion and metastasis.Autophagic activity not only plays a key role in the cellular stress response and maintaining the stability of the internal environment,but it also is closely associated with tumor,involving in the generation and re-cruitment of TAMs precursor cells in the tumor microenvironment and the important regulatory steps of polarization of the precursor cells to TAMs.The study of autophagy-mediated control of TAMs is conducive to a more comprehensive understanding of the tumor micro-environment in the complex regulatory network system,and may open a new situation in cancer treatment.
