[Research progress on anti-alcoholic gastric injury active components and mechanisms of Chinese herbal medicine].

Alcohol is considered to be one of the main causes for gastric injury, and alcoholic gastric injury has been becoming one of the global health problems, which seriously affects the quality of human life. Many studies suggest that the active components extracted from Chinese herbal medicine can effectively reduce the degree of alcohol-induced gastric injury. The active components and its mechanism of anti-alcoholic gastric injury of Chinese herbal medicine reported in recent five years were preliminarily summarized according to the classification of terpenoids, flavonoids, polyphenols, polysaccharides, volatile oils, phenylpropanoids and alkaloids in this paper. The terpenoids could improve oxidative stress and inflammatory response by regulating relevant signaling pathways. The flavonoids are mainly related to antioxidant and anti-inflammatory properties. The polyphenols mainly regulate the level of relevant factors involved in inflammatory pathway, oxidative stress and apoptosis pathway. The polysaccharides could enhance the ability of gastric mucosal defense factor by inhibiting oxidative stress injury and inflammatory response. Phenylpropanoids could enhance the gastric mucosal defense factor. The volatile oils mainly inhibit H~+/K~+-ATPase activity or inflammatory reaction. Alkaloids are closely related to the inhibition of inflammatory response and the improvement of antioxidant system. This paper aims to provide reference for further research and development of Chinese herbal medicine against alcoholic gastric injury.

Omega-3 Fatty acids as Monotherapy in Treating Depression in Pregnant Women: a Meta- Analysis of Randomized Controlled Trials.

Previous studies have reported inconsistent findings regarding the efficacy of omega-3 fatty acids on pregnant women with major depressive disorder (MDD). This meta-analysis was conducted to systematically evaluate the clinical applicability of omega-3 fatty acids in treating depression in pregnant women. Randomized controlled trials (RCTs) that compared omega-3 fatty acids to placebo for short-course treatment of depression in pregnant women were systematically reviewed between March 1999 and April 2015. The search terms used were 'depression', 'omega-3 fatty acids', 'fish oil', 'eicosapentaenoic acid' and 'docosahexaenoic acid'. Standardized difference in means of depression scale was used as the main outcome. Random effect model was used. The effects of baseline depression scores were studying by meta-regression analysis. patients received omega-3 fatty acids. The pooled standardized difference in means was 0.75 with 95% CI= (0.47, 1.04). The baseline depression scores had no effect on the efficacy. None of the recruited patients was withdrawn.
