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.

This paper gives a general introduction of HIV/AIDS treatment with Traditional Chinese Medicine (TCM) in China during the past 20 years. Although the role of TCM in treatment of HIV/AIDS is promising, there is still a long way to go.

Objective To observe the effect of depside salt from Salvia Miltiorrhiza on platelet endothelial nitric oxide synthase(eNOS) activity in health adults.Methods Peripheral venous blood was collected,platelets were isolated with gel-filtration chromatography and incubated with eNOS agonist histamine,eNOS inhibitor L-NAME and different concentrations of depside salt from Salvia Miltiorrhiza(0.1,1,10,100,1000 mg/L) for 30 minutes,then eNOS activity was measured as formation of 3H-L-citrulline from 3H-L-arginine.Results(1)Platelet eNOS activity was significantly inhibited after incubated platelets with L-NAME and increased after incubated with histamine(P

Hormone therapy is a major treatment option for hormone-receptor-positive (HR+) breast cancer. Resistance to hormone therapy is the major reason for disease recurrence and progression. Recent studies have identified several resistance mechanisms that lead to the estrogen-independent growth of HR+breast cancer and were exploited to develop novel target drugs, including cyclin-de-pendent kinases 4 and 6 (CDK4/6) inhibitor, mammalian target of rapamycin (mTOR) inhibitor, epidermal growth factor receptor family inhibitor, vascular endothelial growth factor inhibitor, histone deacetylase inhibitor, fibroblast growth factor receptor inhibitor, insulin-like growth factor receptor inhibitor, and checkpoint inhibitor. These inhibitors are being developed to block resistance pathways and improve the efficacy of hormonal therapy. Among these drugs, the mTOR inhibitor everolimus and the CDK4/6 inhibitor palbociclib are currently approved in the United States to treat metastatic HR+breast cancer. In this study, we summarize the frontier advances in the combination of hormone and target therapies.
