Efficacy, safety and mechanism of Simiaoyongan decoction in the treatment of carotid atherosclerotic plaque: a randomized, double-blind, placebo-controlled clinical trial protocol.

Introduction: Chronic inflammation is the major pathological feature of Atherosclerosis(As). Inflammation may accelerate plaque to develop, which is a key factor resulting in the thinning of the fibrous cap and the vulnerable rupture of plaque. Presently, clinical treatments are still lacking.

[Effect of rapid decompression on rat multifocal electroretinogram].

Objective: To observe the effect of rapid decompression on rat multifocal electroretinogram (mfERG) and to explore the characteristics of the retinal function impairment due to decompression sickness at early stage.

Methods: Twenty rats were randomly divided into 4 groups: normal control (NC) group, safe decompression (SD) group, 0 h and 6 h after rapid decompression (RD0 and RD6) groups. The treated rats in safe decompression group and each rapid decompression group were exposed in hyperbaric cabin and air pressure in the cabin rose up to 1.
