Relying on the experience of designing the WLAN commanding system for medical service indemnity in field hospital,this article describes the technique and the secure of WLAN,the component of hardware and the function of software in the commanding system,which gives a reference to set up field commanding system rapidly at wartime.

OBJECTIVE:To probe into the status quo of medication compliances and problems in the medication of patients with tuberculosis so as to direct their use of drugs.METHODS:Information on medication compliances of tuberculosis patients who experienced regular physical examinations was investigated by interview and questionnaires,and which were analyzed statistically.RESULTS:Of the562cases investigated,54%followed or almost followed medication directions;46%failed to follow normal drug therapy for different reasons.CONCLUSION:The pharmacists should do their utmost to expand the range of pharmaceutical care so as to improve patients'medication compliances.

ObjectiveTo examine the clinical utility of four methods in diagnosis of tuberculous meningitis.Methods A total of 60 patients with tuberculous meningitis were included as study group and another 70 patients with non-tuberculous intracranial infection as control group. Four methods, including conventional acid fast stain,Myobacterium tuberculous culture in BACTEC MGIT 960, real-time lfuorescent quantitative polymerase chain reaction (FQ-PCR) and modiifed acid fast stain, were used to assay the cerebrospinal lfuid specimens for diagnosis of tuberculous meningitis.ResultsThe positive rate was 11.7% (7/60), 6.7% (4/60), 48.3% (29/60), and 61.7% (37/60), respectively in the study group as tested by the four methods. There was signiifcant difference between the four methods in the positive rate (P< 0.05). Modiifed acid fast stain was more sensitive than the other 3 methods in identifying tuberculous meningitis (P< 0.05). This method also could identify the intracellularM. tuberculosis. All the 8 samples from the 4 patients who were positive for culture ofM. tuberculosis were positive in the modiifed acid fast stain.Conclusions The modiifed acid fast staining method is simple, fast, signiifcantly more senstive in detection of the acid fastM. tuberculosis in CSF, either extracellular or intracellular. It is worthwhile to further investigate its usefulness in early diagnosis of tuberculosis meningitis.

Polycystic ovary syndrome(PCOS)is characterized by high heterogeneity and heredity,and its exact pathogenesis is still not clear.Some studies have shown that epigenetic disorders,such as hyperandrogen-induced methyla-tion or acetylation of lysine at different sites(K4,K9,and K27)in histone H3,methylation and demethylation modifica-tion of genes related to steroids,hormone receptors and follicular development,and transcriptional control of microRNA or long noncoding RNA,play a central role in the occurrence and development of PCOS.This article reviews the research ad-vances in epigenetic mechanisms(histone modifications,DNA methylation,and noncoding RNA)of PCOS,in order to provide a reference for the prediction and early prevention of PCOS.
