Objective To study distribution rules of TCM syndrome characteristics of menopausal syndrome; To provide references for clinical treatment and further study.Methods The articles related to menopausal syndrome in CNKI, VIP, Wanfang Data, CBM and TCMDS during Jun. 1983 to Jun. 2013 were retrieved and analyzed. The original data were input into computer and established the menopausal syndrome literature database. Methods of cluster analysis, factor analysis, and frequency analysis were combined to conduct statistical analysis.Results A total of 270 articles and 730 patients were included in the analysis, including 42 syndromes and 73 symptoms. The four diagnostic information of top 9 syndromes was analyzed by clustering and 5 kinds of basic syndrome types were obtained, including liver and kidney yin deficiency, liver depression, heart-kidney disharmony, heart and spleen deficiency, and spleen and kidney yang deficiency; the core symptoms of each syndrome were extracted by factor analysis and frequency dominance method, and the main points of syndrome differentiations were initially established. Conclusion Three methods combined with relevant expert advice were used to initially establish the syndrome diagnosis of menopause syndrome, which can lay a solid foundation for further study.

OBJECTIVE: To study the genetic polymorphisms of short-tandem repeats (STR) for the D13S317 locus among an ethnic Han Chinese population and verify a novel tri-allelic pattern identified for the locus. METHODS: A total of 378 paternity test cases from Guangdong Forensic Authentication Institute from October 17, 2017 to December 28, 2017 were selected as the study subjects. A GlobalFiler^TM Express kit was used for the STR genotyping. Samples suspected for having a novel tri-allelic pattern were verified with a PowerPlex 21 kit. Potential variant of the primer-binding region and flanking sequences underlying the tri-allelic pattern was excluded by molecular cloning and sequencing. RESULTS: Six alleles were detected for the D13S317 locus, with the characteristic distribution frequencies being 8 (29.1%), 9 (13.1%), 10 (15.21%), 11 (24.21%), 12 (13.89%) and 13 (3.44%), respectively. In one of the families, the D13S317 locus of the proband was suspected to harbor a triband allele (8, 9, 10). A re-test has confirmed the result of initial test. Molecular cloning and sequencing analysis of the D13S317 locus in the proband and his daughter has failed to find allelic variants in the primer-binding region and flanking sequence, which has confirmed the novel tri-allelic pattern for the locus. CONCLUSION A novel type 2 tri-allelic pattern (8, 9, 10) at the D13S317 locus has been identified among the ethnic Han Chinese population. The pattern has not been transmitted to the female offspring, and has been included in the international STRBase database for the first time.
