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 evaluate the anti-thrombus activitity of EPR-hirudin (EH), a derivative of hirudin obtained by adding three amino acids at the nitrogen terminus. METHODS: The anti-thrombus activitity of EH was investigated by chromophore substrate method in vitro as well as by rat models of carotid arterial thrombosis and inferior vena cava thrombosis in vivo. RESULTS: The result of anti-thrombin experiment in vitro showed that EH did not produced anti-thrombin activity unless it was cleaved by blood coagulation factors. Then the anti-thrombus feature of EH was confirmed in vivo separately in the rat models of carotid arterial thrombosis and inferior vena cava thrombosis. The formation of arterial clot was inhibited and the weight of venous clot was decreased after administration of EH in a dose-independent manner. However, the blooding time, activated partial thromboplastin time (APTT) and thrombin time (TT) did not significantly increase in EH groups compared with HV and low molecular heparin. CONCLUSION: EPR-hirudin can inhibit the formation of arterial and venous clot and has low risk of blooding.

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.
