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.

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.

BACKGROUND: The problems such as fast drug degradation, great drug loss and poor barrier effect exist when using liquid molecular biomaterial as barriers in preventing tendon adhesion. Accordingly, it has aroused increasing attention to seek for membrane biomaterials as barriers. Simultaneously, it found that tendon cells would proliferate and differentiate under controls of multiple endogenous growth factors that promote tendon endogenous healing. However, it is poorly understood which the specificity factor for tendon healing is. OBJECTIVE: To study effect of epidermal growth factor (EGF) combined with degradable collagen membrane on preventing tendon adhesion and improving tendon endogenous healing. METHODS: Thirty ten-month old leghorn cocks were randomly divided into 3 groups, with 10 animals in each group. The third toe of left foot of each animal was prepared for avulsion model, and sutured with improved Kessler method. The broken ends were encapsulated with EGF combined with degradable collagen membrane (combination group), degradable membrane alone (collagen membrane group) or without treatment (blank control group). Four weeks later, the specimens were evaluated by gross observation, biomechanical test, light microscope and electron microscope. RESULTS AND CONCLUSION: In the combination group, there were a large amount of type Ⅰ collagen inside the sutured tendon, they were closely and lined up in order. The amount of collagen-fibronectin was less and the adhesion obviously was less than the control group. The tendon cells were matured. The adhesion in the collagen membrane group was slightly, there were a large amount of type Ⅲ collagen inside the sutured tendon, which loosely but well organized. In the blank control group, type Ⅰ and Ⅲ collagen arranged crisscrossed, with heavy adhesion. The results suggest that EGF can promote tendon endogenous healing and degradable collagen membrane can prevent tendon exogenous healing, thus, prevent the formation of adhesion.
