Far beyond simulating manual work with the computer system,hospital informatization entails a combination of information technology with hospital professional work.With a fully understanding of working procedure in hospital,an effective concordance based on informatization requirements is conducted so that the management and the collection of the information can follow the information flow,logistics,capital flow,working flow and organization flow.Management mode and organization framework of the hospital are also adjusted.Thus the hospital operation quality and efficiency are improved,and patients are offered seamless and continuous service,which really reflects the service theory: "Patient First".

A backup data center near the primary data center using Storage Area Network is built with Fiber Channel technology. The specific disaster recovery software used to synchronize the two centers a highly reliable safety and expandable data storage management system with adequate redundancy is developed. Thus disaster recovery service can be provided for the hospital information system when disaster happens. To avoid the system risk and maintain the continuity of the hospital's activities the damaged part of the system will be taken over from.

Several models about epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKI)as first-line treatment in advanced NSCLC show different results.Combination with chemotherapy and EG-FR-TKIs did not indicate survival advantage.However,sequential chemotherapy in EGFR-TKIs and a single agent of EGFR-TKIs as first-line treatment of advanced NSCLC have made tremendous breakthrough,and give a new path in individual treatment of advanced NSCLC.Also EGFR mulatious in targeted therapy of advanced NSCLc has a sood predictive value of the etticacy.

Objective To explore the relationship between heart rate variability(HRV)and serum high sensitivity C-reactive protein(hs-CRP)in type 2 diabetic aged patients.Methods Totally 30 aged patients with type 2 DM were enrolled in this study who were selected from the outpatients and inpatients of Department of Gerontology in the Third People's Hospital of Chongqing,and another 30 non-diabetic matched individuals were recruited as control.Their serum hs-CRP and 24 hour-electrocardiography were examined.HRV was assessed by calculating the indices based on statistical operation on RR intervals(time domain analysis)from 24-hour Holter recording,including:standard deviation of normal to normal RR intervals(SDNN),standard deviation of 5-minute mean RR intervals(SDANN)and square root of differences between adjacent NN intervals(rMSSD).Linear correlation analysis was carried out between their serum hs-CRP and HRV.Results HRV parameters of type 2 DM patients were significantly lower than those of non-diabetic patients,but hs-CRP values were significantly higher than those of control.Linear correlation analysis indicated that HRV was in a positive correlation with hs-CRP in type 2 diabetic aged patients.Conclusion Altered autonomic nervous function may be associated with altered serum hs-CRP in aged patients with type 2 diabetes mellitus.

Atrial fibrillation is the most common arrhythmia in clinical practice.However,the therapeutic effects of traditional antiarrhythmic medicines are far from satisfactory,because of the high rate of arrhythmia recurrence and the potential proarrhythmia effect.Recently,with the further investigation of the mechanisms that initiate and perpetuate atrial fibrillation,and the support of extensive data from clinical trials and animal experiments,thera-peutics based on anti-inflammation,antioxidation,regulation on renin-angiotensin-aldosterone system(RAAS)and gap junction may be new therapeutic targets for the treatment of arrhythmia.In this paper,the potential molecular mechanisms involved in these processes and several clinical trials about some non-traditional antiarrhythmic medi-cines were reviewed,in order to propose a new idea about the development of antiarrhythmic medicines.

Myocardial tissue masses were isolated from two human fetus of 10 and 16 week's gestation respectively and they were cultured under the conditions for cultivating the myocardial cells of the rodents. Spontaneous beating occured. In one case the frequency of beating was 21～27 beats/min, and the beating lasted for 30 days until the culture was terminated artifitially. In another case a cell mass continued to beat as long as 75 days with a frequency of 200～290 beats/min, and then stopped spontaneously. The differences in thickness and shapes of the tissue masses would influence the modes of growth after culturing. Thicker tissue mass grew more slowly and the fibroblasts and myocardial cells grew and spreaded out radially, or in band form. In tissue mass with a thin border the marginal myocardial cells bulged out in globular shape in the early stage and then separated from the cell mass and continued to grow. In thin layered tissue mass, because of the rapid overgrowth of the surrounding fibroblasts, the myocardial tissue would grow and overlap them and increased steadily in thickness. This procedure is simple and relatively stable, and possible to retain the long-lasting beating of the myocardial tissus, but it is difficult to obtain a pure myocardial cell culture for cell counts and other quantitative studies.

Enzyme histochemistry of neurons in the enteric nerve plexus of guinea pigs were studied with light microscope semi-quantitatively and microphotometer quantitatively. The results showed that the neurons differ greatly in A1P (alkaline phosphatase), AcP (acid phosphatase), 5'-Nase (5'-Nucleotidase), TPPase (thiamine pyrophosphatase), NsE (non specific esterase) and ChAT (choline acetyltransferase). There were disparities to a certain extent in reactions of MAO (monoamine oxidase), AP (aminopeptidase) and AChE (acetylcholinesterase) among different segments of gastrointestinal between submucous and myenteric plexus, but all neurons were positive for the enzymes stated above. The neurons in each ganglion were relatively similar in the enzyme activities. There were about 50-66% neurons in the enteric nerve plexus showing strong reaction of ChAT, which may be cholinergic neurons. There were significant differences in enzymatic activities, except NsE, between submucous plexus and myenteric plexus statistically. Submucous plexus showed stronger reactions of AcP and AP than those of myenteric plexus, while myenteric plexus showed stronger reactions of A1P, 5'-Nase, TPPase, MAO, ChAT than those of submucous plexus. The ganglia of intramural plexus in stomach were not well developed as those of intestine, especially the submucous plexus of stomach, in which there were only few scattered neurons, and they showed weaker enzyme activities than those of intestine. The enteric neurons in duodenum and proximal colon showed strongest activities for most enzymes among different segments of intestine. The above results indicate that the enteric neurons exist remarkable differences in metabolism and functional states.
