Results showed that the expression of nuclear factor-κB and the levels of tumor necrosis factor-α and interleukin-1β decreased. Simultaneously, the extent of edema in the hippocampus and frontal lobe decreased, and the morphology of the nerve cells recovered to near normal. In addition, fluoxetine treatment displayed a similar effect on post-stroke depression as electroacupuncture at GB 12 acupoint. The results indicate that electroacupuncture at GB 12 acupoint can reduce the levels of cytokines in the hippocampus and frontal lobe of rats with post-stroke depression, and thus provide a neuroprotective effect on post-stroke depression.展开更多

Wangu (GB 12) is a point of the Gallbladder Channel of Foot Shaoyang, located in the depression posteroinferior to the temporal process. And it is a hui point of Foot Taiyang and Shaoyang Channels, with the effects of eliminating pathogenic wind and heat, and tranquilizing the mind. This point is located superior to the attachment point of the sternocleidomastoid muscle, in which there distribute the stem of the lesser occipital nerve, and branches of the posterior auricular artery and vein. It can be needled perpendicularly 0.5-1 cun deep. In clinical practice, the author has applied the point for treatment of various diseases, and obtained quite satisfactory therapeutic results. The following is a report of some illustrative cases. ……展开更多

All located minima were then transferred to the original PES using undeformed optimized potentials for liquid simulations (OPLS) potential function, and minimized by multi-con-former minimization (MCM). For solution-phase calculations, the GB/SA continuum model for water was used. This application of PSS integrated with MCM is proved a feasible method for solving the multiple-minimum problem in the conformational analysis of flexible molecules with cyclic structure.展开更多
