A mouse model of AD was established using the semiantigen 2,4-dinitrofluorobenzene induction method. The lesion scores, transepidermal water loss and p H, and skin histopathology of mice in each group were observed. The expressions of filaggrin, loricrin,and involucrin were detected by the streptavidin peroxidase immunohistochemical method and western blotting, and their mRNA expressions were detected by quantitative polymerase chain reaction.Results: Mice in the WF, ERF, ICF, and PC groups showed reduced skin lesion performance, improved histopathology, decreased skin lesion score, transepidermal water loss and pH, and upregulated expressions of proteins including filaggrin, loricrin, and involucrin, and their mRNAs. The most obvious regulatory effect was observed in the WF group, followed by the ICF, ERF, and PC groups, accordingly.Conclusions: Mahuang Lianqiao Chixiaodou decoction and its disassembled formula can improve the skin barrier function in a mouse model of AD by upregulating filaggrin, loricrin, and involucrin, and their mRNA expressions, and the most optimal effect was noted in the WF group, followed by the ICF and ERF groups, which suggests that the effect of clearing heat and resolving dampness in improving the skin barrier function of AD is more obvious and is one of the key treatments for AD.展开更多

Methods： Randomized controlled trials of all the languages of MahuangFuzi Xixin Decoction on sick sinus syndrome were collected by computer search and manual retrieval. Theretrieval time was from January 2000 to January 2017. According to the inclusion and exclusion criteria, 2reviewers independently selected and extracted data, then evaluated the quality, cross-checked the information andevaluated the quality of menthodology. Through discussion or third reviewer to help solve the divergence, RevMan5.3 software was used to perform meta analysis. Results： A total of 7 documents （n = 612） were finally enrolled,with 358 in Mahuang Fuzi Xixin Decoction group （treatment group） and 254 in control group. Meta analysisshowed that the treatment （86.9%） was more effective than the control （70.1%）, the difference was statisticallysignificant （RR = 1.25, 95% CI：（1.15-1.37）, P 〈 0.001）; the treatment （17.0%） was safer than the control （49.8%）,the difference was statistically significant （RR=0.23,95% CI：（0.06-0.93）, P =0.04）. Conclusion： The existingclinical studies suggest that Mahuang Fuzi Xixin Decoction on sick sinus syndrome is effective and safe; due to thelimited quality of the enrolled documents, the above conclusions need more high-quality randomized controlledtrials to be verified.展开更多

Results: after the effective treatment plan was implemented, the condition improved, especially the children treated with acupoint application + shegan mahuang decoction had a higher total effective rate, a lower incidence of adverse reactions, a good trend in FVC and other levels, and symptoms and signs. The scores were lower, and the children who received acupoint application treatment were relatively poor, and the difference was significant (P<0.05). Conclusion: in the treatment of acute exacerbation of bronchial asthma in children, shegan mahuang decoction combined with acupoint application has obvious application value and high safety, and plays a positive role in further shortening the course of the disease in children.展开更多
