Objective:To analyze and determine heavy metal content in Paridis Rhizoma from different genus and localities,in order to provide a reference for selecting cultivation areas and establishing the quality standard of Paridis Rhizoma of heavy metals content. Method:Microwave digestion method combined with inductively coupled plasma atomic emission spectrometry method (ICP-AES) method were applied to determine the contents of 6 heavy metals,i.e. As,Cu,Hg,Cd,Pb and Cr in 39 samples of Paridis Rhizoma of different genus and localities in Yunnan Province. Cluster analysis,statistical analysis and principal component analysis (PCA) were used to compare the differences of heavy metals contents in different localities and species. Result:The contents of six heavy metals in Paridis Rhizoma met the ISO international standard of Heavy Metal Limit of Traditional Chinese Medicine-traditional Chinese Medicinal Materials. Under the limited value standard of Green Trade Standards of Importing Medicinal Plants and Preparations,the over-standard rate of heavy metal As was 15.4%,the excess rate of Cd was 5.1%,and the excess rate of Pb was 2.6%. The contents of Cu and Hg conformed to relevant requirements. Cluster analysis,statistical analysis and principal component analysis showed that for the same variety,differences in producing places had significant effects on heavy metal content,while differences in species had little effects. Conclusion:The results of this study indicated that the heavy metal content of Paris planted in and around Dali basically conformed to relevant standards. The differences of heavy metal content in Paris were mainly regional differences,which provided a theoretical basis for standardizing the cultivation of medicinal materials and formulating the limit standards of heavy metals for Paridis Rhizoma.

Ulcerative colitis (UC) is a chronic non-specific inflammatory bowel disease, listed as a modern refractory disease by the World Health Organization, which is difficult to recover, whereas it is easy to be attacked repeatedly. UC pathogenesis is closely related to gut microbiota dysbiosis. The gut microbiota interacts with bile acids (BAs), short-chain fatty acids (SCFAs), tryptophan, and other metabolism, immune system, intestinal barrier, etc., which regulate each other and affect the occurrence and development of UC. The active ingredients of traditional Chinese medicine (TCM), single herb and its extracts, and formulae can effectively alleviate UC symptoms by regulating the diversity, structure, composition, and metabolites of gut microbiota. In this review, the TCM based on the regulation of gut microbiota in the treatment of UC and its related mechanism for nearly three years was summarized.
