Qigong and Tai chi are traditional methods of physical and mental training and exercises in East Asia. Their health-promoting effects against various diseases have been studied for a long time, and they have been the subject of many clinical trials and systematic reviews (SRs). The present study aimed to comprehensively evaluate all published SRs on Qigong and Tai chi and to summarize the supporting evidence. ⋯ Thus, Qigong and Tai chi for various diseases and medical conditions have been accumulated. Based on current evidence, the number of publications of Qigong and Tai chi-related articles showed an increasing trend, and most of them were performed in China. Qigong and Tai chi have shown beneficial effects in different age groups and health conditions, including decreasing blood lipid level, reducing blood pressure, facilitating mobility, preventing falls, and improving overall quality of life.

Electroacupuncture (EA) is commonly used to treat cerebrovascular diseases. This study aimed to clarify the mechanisms of action of treatments of cerebral ischemic stroke from the perspective of gut microecology. We used a mouse model and cell cultures to investigate the effects of EA on the intestinal microflora in mice models of middle cerebral artery occlusion (MCAO) and the mechanisms underlying the antioxidant activities of metabolites. ⋯ We confirmed that IPA binds to specific melatonin receptors (MTRs) in target cells and exerts antioxidant effects by adding MTR inhibitors or knocking out the MTR1 gene in vivo and in the oxygen and glucose deprivation/reperfusion models of N2a cell experiments. EA can prevent ischemic stroke by improving the composition of intestinal microbiota in MCAO mice. Moreover, this study reveals a new mechanism of intestinal flora regulation of stroke that differs from inflammation/immunity, namely gut microbiota regulates stroke by affecting IPA levels.

Dandelion (Taraxacum species) is a wild plant with over 2500 species. Flavonoids, phenolic compounds, saponins, sesquiterpenes, and sugars have been detected in the organs of Taraxacum, and for centuries it has been used in traditional medicine for the relief and treatment of various diseases. However, details of its working mechanism remain unclear. ⋯ What's more, we also found that the effects of fresh T. formosanum were much stronger than that of T. mongolicumin HeLa cells. Based on these results, we suggest that T. formosanum may contain specific compound(s) that are potentially useful for cancer therapy. However, much work remains to identify these effective compounds for the future application of Taraxacumto cancer therapy.

Gambogic acid (GA), a natural and bioactive compound from the gamboge resin, has been reported to exhibit many oncostatic activities against several types of malignancies. However, its effects on the progression of oral squamous cell carcinoma (OSCC) remain largely unexplored. To fill this gap, we investigated the anticancer role of GA and molecular mechanisms underlying GA's actions in combating oral cancer. ⋯ Moreover, such induction of HO-1 expression and caspase cleavage by GA was significantly diminished through the pharmacological inhibition of p38 kinase. In conclusion, these results demonstrate that GA promotes cell apoptosis in OSCC, accompanied with the activation of a p38-dependent apoptotic pathway. Our findings provide potential avenues for the use of GA with high safety and therapeutic implications in restraining oral cancer.

Atractylodes lancea (Thunb.) DC. is a herb widely used traditionally for the treatment of gastrointestinal diseases such as gastric ulcer, spleen deficiency, and diarrhea. In China, people fry raw A. lancea (SCZ) together with wheat bran to make bran-fried A. lancea (FCZ). Ancient Chinese texts have documented that FCZ can enhance the function of regulating the intestines and stomach. ⋯ In the PGF mouse model, the above effects were not observed. Rhizoma Atractylodes was effective in alleviating DSS-induced UC in mice, and FCZ was found to be superior to SCZ. The mechanism of action of FCZ and SCZ is mainly related to the regulation of intestinal flora and their associated metabolites.
