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.

Objective To study the appearances and early fetures of sacroiliac joints(SIJ) in ankylosing spondylitis on X-ray film and CT,and to valuate the CT examination of sacroiliac joints in the same groups.Methods The plain X-ray film of 73 cases of SIJ of ankylosing spondylitis which had been proved clinicalhy were studied.All the patients had been examed with CT at the same time.The appearances presented by the two methods were concluded compared and graded,the relationship between them was analyzed with statistics.Results The erosion,cystic lesions of bone and swollen of soft tissues were the early features of sacroiliac joints in ankylosing spondylitis,but the detection rate of them by X-ray was 73%,38%,0.6%,by CT was 86%,72%,3%.They can find on CT and conventional radiography,but the detection rate of them by CT was much higher than that by X-ray plain film(?

Objective:To enhance the immune efficiency of porcine reproductive and respiratory syndrome virus(PRRSV)DNA vaccine,the ORF5 genes were used as candidate genes to construct the recombinant plasmids CpG-pVAX1-ORF5 by pVAX1 as eukaryotic expression vector.The aim is to analyze the immune responses and the effects of CpG-ODN induced by GP5 recombinant plasmids of PRRSV.Methods:Piglets were immunized with recombinant DNA plasmids which expressed PRRSV GP5 for three inoculations.The PRRSV antibody in serum,the concentration of IL-2 and the lymphocyte proliferation test(MTT) in peripheral blood of vaccinated piglets were detected.The vaccinated pigs were challenged intranasally with PRRSV SD2.Results:GP5 DNA immunization with CpG resulted in the production of both PRRSV antibodies and cellular immune(a significant enhancement of a lymphoproliferative response ).The CpG-pVAX1-ORF5 was showed significantly better protection from the PRRSV challenge compared with the control plasmid.This immune response was characterized by a significantly decreased frequency of viraemia with decrease of 80% compared with the control group.There were little clinical symptoms and protection in some extent from lung damage.Conclusion:The results indicate that CpG-ODN could be used as immune adjuvant of PRRSV DNA vaccine.

Cellular autophagy is a major degradative pathway for clearance of aggregate-prone proteins and damaged organelles. It plays an important role in regulating cellular homeostasis, cell growth and development, and disease development. Dysfunctional autophagy contributes to the pathology of various neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and Huntington's disease, in which specific pathological protein accumulation occurs. A growing body of evidence suggests that resveratrol plays a significantly role in the regulation of autophagy and clearance of pathological proteins. Resveratrol is a potential drug for neurodegenerative diseases therapy. This review focuses on the effects of resveratrol on cellular autophagy and clinical application in the control of neurodegenerative diseases.

Berberine is a taste of traditional Chinese medicine.With the progress of research on pharmacology and mechanism of drug action of extensive research,the new mechanism of berberine was revealed through a series of clinical trials,the clinical indications continue to expand,and berberine has a therapeutic effect in digestive and endocrine system disease.The current study confirmed that berberine not only has the broad-spectrum antibacterial activity,but also plays a strong anti-inflammatory and immune regulatory role,which makes more and more research began to concern its application value in the diseases of respiratory system.The strong anti-inflammatory effect of berberine cau effectively relieve the airway inflammation of patients who are suffering from chronic obstructive pulmonary,and the broad-spectrum antibacterial effect brought hope for the treatment of tuberculosis and pneumonia.The subsequent animal and clinical studies have confirmed that berberine can effectively improve the symptoms of respiratory system diseases,and play a role in the treatment.

AIM: To achieve an optimum manufacturing process for acetaminophen extended release tablets. METHODS: To evaluate and set the manufacturing process according to the compressibility of the granule and the dissolubility of the finished tablets. RESULTS & CONCLUSION: The results showed that the bi-layer tablet technology was the most preferable pro- cess. The in vitro dissolution behavior and the in vivo bioavailability of the tablets are comparable to those of the imported products from McNEIL Consumer Healtheare Co. USA.

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.
