Clinical teaching quality directly affects the training of medical talents.It is of great significance for improving the quality of clinical teaching and training medical talents to strengthen clinical teaching management and to carry out clinical teaching research.On the basis of investigation and analysis of clinical teachers, interns and teaching activities in the hospital, the author introduced the PDCA method of the total quality management into the teaching management, and analyzed the effect of its dynamic circulation, to explore a suitable scientific management mode of clinical teaching for the hospital, so as to realizing the continuous optimization of teaching quality.

OBJECTIVE:To observe on the curative effect of compound glycyrrhizin in the treatment of chronic hepatitis B with hepatic fibrosis.METHODS:146cases of chronic hepatitis B with hepatic fibrosis were administered by i.v.drop daily for4weeks with compound glycyrrhizin injection40ml～100ml,into which5%glucose injection(250ml)was added,then a sequential therapy was adopted in which all the patients were treated with50mg oral compound glycyrrhizin tablets3times per day for3months.RESULTS:The total effective rates after4weeks of first stage treatment and the sequential therapy were67.12%and81.51%(P

High-voltage-activated (HVA) Ca channels are widely expressed in the nervous system. They play an important role in pain conduction by participating in various physiological processes such as synaptic transmission, changes in synaptic plasticity, and neuronal excitability. Available evidence suggests that the HVA channel is an important therapeutic target for pain management. In this review, we summarize the changes in different subtypes of HVA channel during pain and present the currently available evidence from the clinical application of HVA channel blockers. We also review novel drugs in various phases of development. Moreover, we discuss the future prospects of HVA channel blockers in order to promote "bench-to-bedside" translation.
