RESUMO
Aim To investigate the mechanism of curcumin inhibition of oxidative stress on osteogenic differentiation and its dose-dependent anti-osteoporosis effect. Methods Cellular oxidative stress models were used, different concentrations of curcumin were added to determinethebone formation markers, and the potential signaling pathways involvedwere detected. Meanwhile, the mouse model of osteoporosis ( ovariecto- mized, 0VX) was used to confirm its effect against osteoporosis. Results In vitro experiments found that low concentrations of curcumin (1-10 μmol · L
RESUMO
Objective:To investigate the clinical efficacy of Gancao Xiexintang combined with vitamin B12 on recurrent oral ulcer (ROU) in children. Method:Totally 116 children with ROU admitted in Jiangxi Provincial Children's Hospital from June 2016 to June 2018 were divided into observation group and control group on the basis of random number table,with 58 cases in each group. The control group was orally treated with vitamin B12, while the observation group was orally treated with Gancao Xiexintang in addition to the therapy of the control group. All of the children were treated for 14 days. Clinical efficacy, changes of T lymphocyte subset (CD3+, CD4+, CD8+, CD4+/CD8+), ulcer area, content of oral flora (veillonella, streptococcus) before and after treatment, and side effect were compared between the two groups. Result:The overall effective rate of the observation group was 96.6%(56/58), which was much higher than 84.5%(49/58) of the control group (P+, CD4+, CD4+/CD8+in peripheral blood, but lower CD8+compared with those before treatment (P+, CD4+, CD8+, CD4+/CD8+) indexes in observation group was improved more significantly (PPPPPConclusion:In treating ROU in children, the combination of Gancao Xiexintang and vitamin B12 can significantly correct imbalance of T lymphocyte subset, promote the recovery of oral ulcer, and positively regulate oral micro-ecological environment, with an exact curative effect and high patient tolerance.
