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.

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.

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.

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. This article reviewed the new techniques and methods for hemiplegic patients after stroke. The main techniques and methods includeed bilateral isokine-matic training, mirror neuron system, gymnastics rods training, music therapy, motor imagery, upper limb rehabilitation robot, virtual reality, constraint induced movement therapy, functional electrostimulation, electromyographic biofeedback therapy, transcranial magnetic stimulation, neurophyisological therapy and so on.

Objective To investigate the difference of TCM body constitution betweenpeople of the Shimian county and Chengdu city. Methods 200 sub-health patients in clinic of Shimian TCM Hospital were selected randomly. Another 200 sub-health patients in clinic of the Second Sichuan Province Hospital of TCM wererandomly selected. The two groups were identified with TCM body constitution based on the clinical symptoms, tongue, pulse condition, etc. Comparisons on body constitution were made between the two groups. Results In Chengdu, patients withbalance constitution and Qi deficiency constitution (respectively have the proportion of 33.0% and 20.0%)were significantly higher than thoseof Shimian County(the proportion of the two wererespectively 4.0% and 6.0%);while Shimian County have a significantly higher ratio of phlegm dampness and blood stasis constitution(43.5% and 13.0%)than those in Chengdu city(the proportion of the two wererespectively 8.0%and 4.0%), P<0.01. Conclusion Because of different regions, the population constitution ratio wasdifferent, so the disease tendency wasalso somewhat different. Therefore, physicians should give full consideration to the regional factors in diagnosing and treating patients.

Objective To construct a simple method for the measurement of activity of S-homocysteine methyltransferase (HMT),and explore the best processing condition for HMT and the preservation of HMT.Methods HMT was expressed in pro-karyotic system by using genetic engineering technology,then was purified by using affinity and Sephadex G1 5 chromatography. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE)was performed to identify the physicochemical and bio-logical properties of target protein.Based on the principle of 5 ,5′-disulfide-double (2- nitro benzoic acid)(DTNB)could react with sulfydryl compounds rapidly,the reduction of homocysteine was detect to evaluate the activity of enzyme,then the best processing conditions of HTM were determined.Activity of enzyme,preserved in preservation solution with or without glycerol and preserved under different temperatures,was detected.Activity remaining ratios were detected and compared between HMT preserved in pres-ervation solution with different protective agents of different concentration and preserved by cryodesiccation.Results The purity of recombined HMT was above 95%,with molecular weight of 36 000 and excellent catalytic activity,and the catalytic activity was 2 000 U/mg.The optimum condition for the detection of biological activity was using HEPES buffer of pH 7.4 at 37 ℃ and reac-tion for 25 min.Glycerol could significantly prolong the preserving time of HMT,and half activity of HMT could be remained for six months.The reservation rates of activity of HMT,preserved in preservation solution with mannitol and trehalose,were 104%and 100%,respectively.Conclusion HMT could be obtained through genetic engineering.A simple test method of HMT was es-tablished,and the best processing conditions and preserving methods of HMT were determined,which laid a foundation for clinical application.

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.
