Cl~- localization and periodic acid-silver methenamine techniques have been used for ultrastructural studies on parietal cells of mouse stomach. Cl~- is located only in the intracellular canaliculi (IC) and intercellular space (IS)of parietal cells. The tubulovesicular system (TS) shows various reactions in periodic acid-silver methenamine staining. The positive reaction was demonstrated in the TS which is located near the apical membranes. This indicates that acid secretion is accompanied by polysaccharides secretion in which the TS takes part, and the polysaccharides secretory activity shows its cyclicity which is characterized by the changes of amounts of secretion. The cycle of parietal cells do not synchronize.

Along with the popularization and application of the computer, masses of information could be achieved from the internet, ensuring the well operation of internet is becoming the prior issue. The paper introduces some successful experiences in ensuring the well operation of internet, including broadening the broadband communications, adding extra network firewall, purchasing products for network safety management, installing anti -virus software, regulating the access to the internet, etc.

Though implementing the quality management system of ISO9000 series standard in the hospital,it enables to make the nursing quality in a controlled state and make every service and operation of nursing staff have regulations to abide by.According to ISO9000 series standard,implementing the management of“procedureization”makes the nursing work closed to the need of patients and satisfies them by stipulating each workflow clearly.

Objective： To investigate the modification of GABAA receptor subunits in audiogenic seizure rat cortex and hippocampus when rendered tolerant to flurazepam. Methods： Rats were administrated with flurazepam for two weeks, which resulted in tolerance to flurazepam, in the absence of behavioral signs of withdrawal. GABAA receptor subunits α1, α3, α5, γ2L and γ2S were assayed using quantitative competitive RT-PCR in rat frontparietal motor(FrPaM) and hippocampus. Results： In FrPaM, the contents of mRNA encoding for α1, α3,　γ2L and γ2S were all significantly decreased (24%,17%,35% and 45% respectively),whereas that of α5 was significantly increased (33%) compared with the control. In hippocampus, α1, γ2L, and γ2S mRNA contents were significantly decreased (33%, 35%and 27% respectively). Conclusion： The accomodated change in GABAA receptor subunits α1, α3, α5,γ2L and γ2S in FrPaM and hippocampus may be associated with the mechanism of flurazepam tolerance in audiogenic seizure rats.

The medical moral unders surveillance is not only an important content of building medical ethics,but also a powerful guaranty of bringing the medicine under control by moal and law.The author purposed the meanings、method and principles of the medical moral under surveillance in order to make the people pay attention and reserach more deeply.

Objective To evaluate and compare the therapeutic effects of suprapubic transvesical prostatectomy (SPPC), Madigan prostatectomy (MPC) and transurethral electrovaporization ablation prostatectomy (TUVP) for the treatments of symptomatic BPH. Methods 216 symptomatic BPH patients randomly underwent SPPC(n=87), MPC(n=45) or TUVP(n=84) respectively and their therapeutic effects were evaluated. Results There are significant improvements in symptoms and physical signs in each group after operation. The morbidity rates of post-operative complications in SPPC,MPC and TUVP were 31 0%,11 1%,13 1% respectvely. SPPC group showed the longest average operative time and the most blood loss, both of which were the least in TUVP group. Conclusions SPPC was the most effective among the three procedures, but the trauma of SPPC to the patient was the most. Complication of MPC was the least. TUVP was the safest procedure with the least injury.

Objective By comparing the prevalence of mental disorders and social demographic characteristics, to analyze the influencing factors of mental disorders in Xiamen city residents. Method Using multi-stage stratified cluster random sampling, 12 071 subjects aged 18 years and older were identified in Xiamen city. Eventually 10 764 subjects completed the survey, including 4 957 males, 5 807 females, 8 588 urban population and 2 176 rural population. The subjects were screened with the expanded version of GHQ-12, the Structured Clinical Interview for DSM-Ⅳ-TR as a diagnostic tool, and made a determination whether they had mental disorder and specific diagnosis. Result The overall prevalence of mental disorders in Xiamen city was lower than that in other provinces and cities; it was only 3.46%(Shandong province 19.48%, Zhejiang province 17.27%, Qinghai province 18.04%, Hebei province 16.24%, Tianshui city 17.90%, Chengde city 17.71%, Baoding city 13.62%). The one of most common mental disorders was the alcohol use disorders in various provinces and cities, except in Xiamen city. The constituent ratio of Xiamen residents surveyed was 79.78%for urban, higher than those of other provinces and cities (Shandong province 24.91%,χ2=6 624.955,P<0.001;Zhejiang province 32.95%,χ2=3 601.752, P<0.001;Qinghai province 23.55%,χ2=4 991.289,P<0.001;Hebei province 15.95%,χ2=11 547.016,P<0.001;Tianshui city 16.05%,χ2=6 484.483,P<0.001;Chengde city 15.60%,χ2=2 930.811,P<0.001;Baoding city 11.80%,χ2=6 973.770,P<0.001). Most residents of Xiamen enjoyed at least one kind of health insurance (83.06%), higher than those of other provinces and cities (Zhejiang province 23.30%,χ2=8 868.617,P<0.001;Hebei province 8.68%,χ2=17 434.576,P<0.001;Tianshui city 11.20%,χ2=10 862.305, P<0.001;Chengde city 8.69%,χ2=5 884.478,P<0.001;Baoding city 9.54%,χ2=10 728.632,P<0.001). Conclusion The overall current prevalence of mental disorders in Xiamen city residents was lower than those of other provinces and cities. The reasons may be that there was higher degree of urbanization, better health care, no heavy drinking habits and other factors. There might be other protective factors which need to be further studied.

The incidence of upper limb dysfunction of stroke patients was high, and the recovery was difficult, which seriously impact-ed their activities of daily living and quality of life.
