Efficacy and safety of moxibustion for menstrual irregularities: A protocol for systematic review and meta-analysis.

BACKGROUND: Menstrual irregularities (MI) is 1 of the most common clinical gynaecological diseases, with abnormal menstrual cycles, abnormal bleeding, and abdominal pain before or during menstruation as the main clinical manifestations. In modern medicine, abnormalities in the function of the pituitary gland, hypothalamus, and ovaries can affect menstruation. Currently, hormone levels in the body are mostly regulated by hormonal drugs, but these drugs can lead to hormonal imbalance, which can lead to adverse reactions. Many clinical studies have reported that moxibustion has a good effect on MI treatment, but there is no relevant systematic review. So the purpose of this study is to evaluate the effectiveness and safety of moxibustion in treating MI. METHODS: The following 8 electronic databases will be searched, including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Web of Science, Chinese Scientific Journal Database, Wanfang Database, and Chinese Biomedical Literatures Database from their inception to 1 December 2020 without any restrictions. Researchers retrieve the literature and extracted the data, evaluation of research methods, quality of literature. The outcomes will include total effective rate, incidence of any adverse events. We use the Cochrane Risk of a bias assessment tool to evaluate methodological qualities. Data synthesis will be completed by RevMan 5.3.0. RESULTS: We will show the results of this study in a peer-reviewed journal. CONCLUSIONS: This meta-analysis will provide reliable evidence for treatment of menstrual irregularities.

Alleviation of plasma homocysteine level by phytoestrogen α-zearalanol might be related to the reduction of cystathionine ß-synthase nitration.

Hyperhomocysteinemia is strongly associated with cardiovascular diseases. Previous studies have shown that phytoestrogen α-zearalanol can protect cardiovascular system from hyperhomocysteinemia and ameliorate the level of plasma total homocysteine; however, the underlying mechanisms remain to be clarified. The aim of this research is to investigate the possible molecular mechanisms involved in ameliorating the level of plasma homocysteine by α-zearalanol. By the successfully established diet-induced hyperhomocysteinemia rat models, we found that, after α-zearalanol treatment, the activity of cystathionine ß-synthase, the key enzyme in homocysteine metabolism, was significantly elevated and level of nitrative stress in liver was significantly reduced. In correlation with this, results also showed a decreased nitration level of cystathionine ß-synthase in liver. Together data implied that alleviation of plasma homocysteine level by phytoestrogen α-zearalanol might be related to the reduction of cystathionine ß-synthase nitration.

[Controlled study of needle warming therapy and electroacupuncture on simple obesity of spleen deficiency type].

OBJECTIVE: To compare therapeutic effects of needle warming therapy and electroacupuncture on simple obesity with spleen deficiency. METHODS: Sixty-eight cases of simple obesity with spleen deficiency, including water-dampness retention due to spleen deficiency, qi-deficiency of the lung and spleen, yang-deficiency of the spleen and kidney, were randomly divided into a needle warming therapy group (n = 36) and an electroacupuncture group (n = 32). Zhongwan(CV 12), Shuifen (CV 9), Qihai (CV 6), Zhongji (CV 3), Tianshu (ST 25), Shuidao (ST 28), and so on were selected as main acupoints in the both groups. Their therapeutic effects and body mass indexes were observed. RESULTS: The total effective rate was 88.9% in the needle warming therapy group and 71.9% in the electroacupuncture group with a significant difference between the two groups (P < 0.05); and there was a significant difference between the two groups in decrease of body mass index (P < 0.05). CONCLUSION: Needle warming therapy has definite and long-term therapeutic effect on simple obesity with spleen deficiency.
