Not only does autophagy play a vital role in maintaining kidney cell survival and homeostasis,but al-so it is involved in the pathophysiology of several kidney diseases. Recent studies have indicated that autophagy was ac-tivated in kidney cells during acute kidney injury and its regulatory mechanism was unclear. Autophagy activation in kidney may be associated with oxidative stress, endoplasmic reticulum stress, hypoxia inducible factor-1α, p53 and Bcl-2 family. The role of autophagy in acute kidney injury is still controversial. Most believe that it plays a protective role during acute kidney injury. Therefore autophagy will become a novel and potential target for the prevention and treatment of acute kidney injury.

Objective:To preliminarily study the effect of Louqin Zhisou decoctions with the mechanism of clearing heat and resol-ving phlegm on the blood level of neutrophil elastase ( NE) in the rat model of acute exacerbation of chronic obstructive pulmonary dis-ease ( AECOPD) . Methods:The rat model of AECOPD was established by passive cigarette smoking, intratracheal instillation of li-popolysacchricle ( LPY) and intranasal instillation of staphylococcus aureus. Totally 60 AECOPD rats were randomly divided into 3 groups, the model control group (n=20), ambrohexel group (n=20), and Louqin Zhisou decoctions group (n=20). NE was detec-ted by ELISA. Results:Compared with that before the treatment, NE in ambrohexel group and Louqin Zhisou decoctions group was de-creased significantly(P<0. 01). Conclusion:Clearing heat and resolving phlegm method probably can decrease NE by reducing air-way mucus hypersecretion and obstruction in AECOPD rats.

Objective:Using the information technology of knowledge element theory to analyze the content of the ancient Chinese medicine book Nv Ke Xin Fa, and to explore the original thinking and implicit knowledge of the author of the book Nv Ke Xin Fa. Methods:Based on the theory and technology of knowledge element, the indexing data was read as logical data by using MS SQL Server database and then the knowledge graph of traditional Chinese medicine was constructed by using neo4j database.Results:There are 345 knowledge bodies and 1 478 knowledge elements in the Nv Ke Xin Fa, mainly including prescription name (280), composition (275) and usage (224); There are 711 semantic types, mainly including prescriptions (232), etiology and pathogenesis (221), syndrome manifestations (125) and treatment (88); 187 semantic associations, mainly syndrome differentiation and treatment (172); Knowledge of semantic association.There are 34 body types, with leucorrhea (16), amenorrhea (13), blood Avalanche (13) and asthenia (13). Conclusions:Zheng Qinyu paid attention to distinguishing the texture of leucorrhea in the treatment of leucorrhea, put forward the pathogenesis and treatment principles and methods of leucorrhea in the stages of "before childbirth" and "after childbirth", and made it clear that the application scope of Buzhong Yiqi Decoction involves menstruation, leucorrhea, pregnancy and the whole cycle of childbirth.Mrs Zheng Qinyu pays great attention to the protection on the spleen and stomach of the middle coke and regulation of Qi that could rise and fall, which could provide a reference for modern clinical diagnosis and treatment of leukorrhagia diseases.

With the rapid development of information technology， research on ancient TCM books has shifted from the traditional collation and digitization into intelligent knowledge service， thereby achieving the deep integration of ancient TCM books collation and clinical needs. Based on the clinical problem and knowledge element theory， we implemented in-depth indexing and knowledge mining for 600 kinds of ancient TCM books， built a knowledge sharing service platform for ancient TCM books by integrating database， cloud platform， knowledge graph and other technologies， and carried out the thematic literature research and developed databases for four major diseases including stroke， heart failure， liver cirrhosis， and diabetes. The digital intelligence products have been applied in hundreds of hospitals for evaluation and feedback. Finally， through "digital processing plus intelligent application"， the two-way interaction between ancient TCM books and current clinical practice is realized， and the path and paradigm of ancient TCM books knowledge serving the modern prevention and control of major diseases is formed， providing reference for the innovative utilization of ancient TCM books.
