Transcatheter aortic valve implantation: Present and development trend / 中南大学学报(医学版)

Currently,although surgical aortic valve replacement (SAVR) is still the golden standard in treatment of severe aortic stenosis according to the guideline,transcatheter aortic valve implantation (TAVI) is gradually becoming a common treatment for patients who are prohibitive or in high risk for SAVR.Recently,the valve manufacturers,including medical companies in China,are making their utmost to develop valve device,leading remarkable results achieved by TAVI.With the complications being controlled,TAVI displays promising future.It is likely that TAVI is expected to become a substitute for SAVR to treat patients with aortic stenosis or even aortic regurgitation.

Studies on comparison and classification of Angelica sinensis from different areas in Gansu province / 中国中药杂志

<p><b>OBJECTIVE</b>To compare and classify the samples of Angelica sinensis from 36 different areas in Gansu province.</p><p><b>METHOD</b>The HPLC was used to detect samples, and the computer aided similarity evaluation was used to analyze the fingerprints.

Sedative and Anti-stress Action of Shenqiwuweizi Capsule / 中国药房

OBJECTIVE: To study the sedative and antistress action of Shenqiwuweizi capsule. METHODS: The sedative and hypnotic experiments were made to observe the action of Shenqiwuweizi capsule on the mice's sleep induced by pentobarbital sodium at subthreshold dosage or hypnotic dosage. The swimming and hypoxia tolerance experiment were performed to observe the effects of Shenqiwuweizi capsule on the swimming time and hypoxia tolerance time in mice. RESULTS: Shenqiwuweizi capsule could obviously prolong the sleeping time of mice induced by pentobarbital sodium, increase the number of sleeping animals caused by pentobarbital sodium at subthreshold dosage, and significantly prolong the time of swimming and hypoxia tolerance in mice. CONCLUSION: Shenqiwuweizi capsule had sedative and anti-stress action.
