To study the protective effect and the mechanism of asiatic acid (AA) from Potentilla chinensis on alcohol hepatic injury in rats. Male Wistar rats were randomly divided into six groups: the normal control group, the AA control group (8 mg · kg(-1) AA), the model group (5.0-9.0 g · kg(-1) alcohol) and high, medium and low-dose AA-treated groups (alcohol + 8, 4, 2 mg · kg(-1) AA). Each group was orally administered with the corresponding drugs once a day for 24 weeks. Approximately 1. 5 hours after the final administration, all rats were killed, and their blood samples and hepatic tissues were collected. The AST and ALT in rat serum and the contents of MPO, TNF-α, IL-1β, SOD, GSH-Px, GSH-Rd and MDA in hepatic tissues were detected. The expressions of NF-κB, TLR4, CD14, MyD88, TRIF and protein expression in hepatic tissues were measured by western blot. The pathological changes in liver tissues were observed by histological examination. The results showed that compared with the model group, the AA-treated groups showed significant decreases in serum ALT, AST and MDA and increases in the activities of SOD, GSH-Px, GSH-Rd and MPO. Moreover, AA markedly inhibited the expressions of TNF-α, IL-1β, TLR4, CD14, MyD88 and NF-κB. The histological examination showed alleviated hepatic issue ijury to varying degrees. In short, asiatic acid (AA) from P. chinensis could protect alcohol-induced hepatic injury in rats. Its mechanism may be related to the inhibition of NF-κB inactivation and the reduction of inflammatory response.

Objective:To investigate the effects of pre-existing antibody on seroconversion rate after influenza vaccination.Methods:This study recruited 1 900 healthy volunteers to receive influenza split vaccines in Xinjiang Uygur Autonomous region and Yunnan Province from September 2009 to October 2018. Hemagglutinin agglutination inhibition assay was used to detect the titers of specific antibodies in blood samples collected before vaccination and 28 d after vaccination and the effects of pre-existing antibody on the seroconversion to different influenza vaccine components were analyzed.Results:Trend analysis showed that with the increasing titer of pre-existing antibody, the seroconversion rates to A/H1N1, A/H3N2, B/Victoria and B/Yamagata vaccine components were gradually decreased (χ 2=121.76, P<0.001; χ 2=67.58, P<0.001; χ 2=45.25, P<0.001; χ 2=54.55, P<0.001). After adjusting for factors such as region, gender and age, multivariate logistic regression showed that pre-existing antibody titer equal to or higher than 40 was an independent factor that affected the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, and the adjusted OR (95%CI) values were 2.50(2.00-3.13)、1.64(1.35-2.00) and 2.50(1.79-3.45), respectively. Conclusions:The seroconversion rate to each vaccine component was negatively correlated with the pre-existing antibody titer. The factor that pre-existing antibody titer equal to or higher than 40 was detrimental to the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, but had no significant influence on B/Yamagata seroconversion.
