Objective Observe the tongue and pulse characteristics of PCOS patients with phlegm-damp syndrome,explore a model for identifying PCOS patients with phlegm-damp syndrome,and provide certain objective tongue and pulse diagnostic indicators with TCM characteristics for clinical treatment.Methods A total of 172 medics were recruited from the Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine,the Shanghai Hospital of Traditional Chinese Medicine,and Shanghai University of Traditional Chinese Medicine.Including PCOS group(including 68 cases with phlegm-damp syndrome and 38 cases without phlegm-damp syndrome),postmenstrual period group(35 with phlegm-damp syndrome),and normal control group with phlegm-damp syndrome(31).The Smart TCM-Ⅰ type of TCM physiological information analysis system was used to collect tongue image information(including parameters of tongue color and tongue coating)and pulse image information(including amplitude and time domain parameters of pulse wave).Results Comparison of tongue parameters showed that compared to the menstrual late phase group with phlegm-damp syndrome,the PCOS group with phlegm-damp syndrome showed significantly higher levels of TC H,TC TIP G,TC TIP B,and TC TIP H,but lower TC TIP S;Compared to the control group with phlegm-damp syndrome,the PCOS group with phlegm-damp syndrome exhibited significantly lower levels of TC ROOT R,TC ROOT V,CC R,CC G,CC B,CC V,CC MID R and CC MID V;Compared to the control group with phlegm-damp syndrome,the menstrual late phase group with phlegm-damps syndrome showed significantly lower levels of TC H,TC R,TC B,TC G,TC V,TC MID H,TC TIP G,TC TIP B,CC R,CC H,CC V,and CC MID H,but higher TC TIP S.The above differences were all significant(P<0.05).Comparison of pulse wave parameters showed that compared with the normal group,the PCOS group showed increased values in H4/H1 L、T4/T L、W1/T L、H2/H1 R、H4/H1 R、W1/T R、H2/H1 L,and T1/T L,while T5/T4 L was decreased;In the menstrual late-phase group,H4/H1 L、H5/H1 L、W1/T L、W1/T R、H2/H1 L、T1/T L、T4/T L、T1/T4 L、H2/H1 R,and H4/H1 R were higher,whereas T5/T4 L were lower.The above differences were all statistically significant(P<0.05).The nomogram diagnostic model for phlegm-damp syndrome of PCOS was established by combining tongue and pulse diagnosis parameters.And the model had a certain reliability.Conclusion The certain objective parameters of tongue and pulse diagnosis can help predict to a certain extent the phlegm-damp syndrome of PCOS,postmenstrual period,and normal control group with phlegm-damp syndrome and non-phlegm-dampness syndrome of PCOS.

Objective To explore the characteristics of TCM syndromes in patients with coronary heart disease complicated with hypertension and diabetes based on latent structure model.Methods A multi-center cross-sectional study was used to collect the four diagnostic information of patients with coronary heart disease by using the Four Diagnostic Collection Scales of TCM developed by our research group,and a clinical database was established.Combined with frequency analysis and expert opinions,the four diagnostic information was screened to construct a latent structure model.Results Totally 702 patients with coronary heart disease complicated with hypertension and diabetes were collected.A total of 40 high-frequency four-diagnosis symptoms were screened,and 18 latent variables were obtained by latent structure model analysis.The model BIC score was-17 604.38.The latent variables in the model were comprehensively clustered,and it was found that the syndrome elements of disease location in patients with coronary heart disease complicated with hypertension and diabetes were mainly heart,liver,kidney,etc.,and the syndrome elements of disease nature were mainly qi deficiency,yin deficiency,qi stagnation,phlegm turbidity,blood stasis,etc.The syndrome types were mainly phlegm and blood stasis syndrome,spleen and kidney yang deficiency syndrome,liver depression and qi stagnation syndrome,liver and kidney yin deficiency syndrome,damp-heat intrinsic syndrome,and the mutual information and information coverage between each syndrome type and the four diagnostic information were suggested.Conclusion Latent structure model analysis can provide a qualitative and quantitative basis for the syndrome classification of patients with coronary heart disease complicated with hypertension and diabetes.

Objective:To analyze TCM tongue diagnosis related research on coronary heart disease (CHD) at home and abroad using the method of bibliometrics; To provide reference for further research on clinical diagnosis and treatment of CHD.Methods:Research literature about TCM tongue diagnosis for CHD was retrieved from CNKI, VIP, CBM, Wanfang Data, PubMed, Embase, Cochrane Library and Web of Science from the establishment of the databases to December 31st, 2022. The key features of literature related to tongue diagnosis from CHD, including publication volume, region, institution, authors, and research hotspots, were analyzed using BICOMBS2.0, CiteSpace 6.1.R6, and Excel 2019 software.Results:Totally 364 Chinese articles and 5 English articles were included. Liaoning University of Traditional Chinese Medicine was the institution that published the most relevant research in Chinese, and Shanghai University of Traditional Chinese Medicine was the institution that published the most relevant research in English. Professor Wang Yiqin of Shanghai University of Traditional Chinese Medicine was the author with the largest number of publications in both Chinese and English, and the authors with the largest number of publications on Chinese research worked closely cooperate with each other. Chinese research focused on syndrome characteristics of CHD, objectification of tongue diagnosis and data mining based on the clinical experience of renowned TCM practitioners; the English research topic included modern data collection and analysis and expert consensus.Conclusions:The research team of tongue diagnosis for CHD in China has begun to take shape. There are few English articles on tongue diagnosis for CHD, and the development level is relatively lagging behind. In the future, different institutions and researchers need to strengthen international cooperation to enhance the international influence of TCM diagnostics.
