Clinical practice of traditional Chinese medicine for the treatment of postmenopausal osteoporosis: a literature review.

OBJECTIVE: This study aimed to evaluate the effectiveness and safety of traditional Chinese medicine (TCM) for postmenopausal osteoporosis (PMOP). METHODS: We conducted a computer literature search in five databases and comprehensively extracted all kinds of information from each article. Traditional Chinese medicine inheritance support system (TCMISS) V2.5 was adopted to perform association analysis. The effectiveness, safety and methodological quality were analyzed using randomized controlled clinical trials (RCTs). RESULTS: A total of 2880 related articles were collected. Finally, 423 articles which included 312 RCTs were included for in-depth analysis. We collected 369 Chinese medicine prescriptions and found that the top three frequently used herbs in the treatment of PMOP were Epimedii Folium (Yinyanghuo), Rehmanniae Radix Praeparata (Shudihuang) and Angelicae Sinensis Radix (Danggui). The top Chinese patent medicine was Gushukang capsule. No serious adverse reaction (AR) had been reported in the Chinese medical treatment group. CONCLUSION: The effectiveness of TCM in treating PMOP needs to be further explored, and the safety is good. Therefore, high-quality evidence is urgently needed to supplement.

Antagonistic effects of two herbs in Zuojin Wan, a traditional Chinese medicine formula, on catecholamine secretion in bovine adrenal medullary cells.

In order to research the target of superior efficacy and lesser side effects, combination of herbal materials has been applied to phytotherapy for thousands of years in China and some other countries. Zuojin Wan (ZJW), a famous traditional Chinese medicine formula, is used in treating gastric diseases in China. It is composed of two herbs, Rhizoma Coptidis (RC) and Fructus Evodiae (FE) in the ratio of 6: 1(w/w). In the present study, we examined the effects of ZJW, RC, FE and active components isolated from these herbs on catecholamine (CA) secretion and intracellular calcium ([Ca(2+)](i)) in cultured bovine adrenal medullary cells. Extracts of ZJW and RC and berberine, palmatine and jatrorrhizine, components of RC, all inhibited CA secretion and rise in [Ca(2+)](i) induced by acetylcholine (ACh), veratridine (Ver) and/or 56 mM K(+). On the other hand, extract of FE, evodiamine and rutaecarpine, components of FE, stimulated CA secretion and rise in [Ca(2+)](i) induced by ACh. Furthermore, different proportions of RC and FE caused different responses in CA secretion. The present findings suggest that two herbs in ZJW have opposite effects, i.e., inhibitory effect of RC and stimulatory effect of FE, on CA secretion induced by acetylcholine in cultured bovine adrenal medullary cells.
