Factors Associated With Coronary Heart Disease Among Adult Residents in Jinjiang District,Chengdu City / 中国医学科学院学报

Objective To analyze the prevalence of coronary heart disease among community residents over 18 years old in Jinjiang district of Chengdu city,Sichuan province,and explore its associated factors,so as to provide a reference for the prevention and control of coronary heart disease in communities.Methods From October 15 to November 10 in 2021,a total of 5220 adult residents from 33 communities in Jinjiang were selected by multi-stage stratified random sampling for face-to-face questionnaire survey,physical examination,and laboratory blood test.Binary Logistic regression was employed to predict the factors associated with coronary heart disease among adult residents in Jinjiang.Results The crude and standard prevalence rates of coronary heart disease among 5220 adult residents were 3.39% and 2.11%,respectively.Logistic regression analysis showed that age (OR=1.068,95%CI=1.051-1.086,P<0.001),depressive symptoms (OR=1.639,95%CI=1.037-2.591,P=0.034),regular exercise (OR=0.584,95%CI=0.378-0.902,P=0.015),elevated blood pressure (OR=3.529,95%CI=2.344-5.312,P<0.001),dyslipidemia (OR=2.152,95%CI=1.291-3.587,P=0.003),and core knowledge score of chronic diseases (OR=1.144,95%CI=1.066-1.228,P<0.001) were associated with coronary heart disease among adult residents in Jinjiang.Conclusions The prevalence of coronary heart disease is high among adult residents in Jinjiang district of Chengdu.The urban residents who are older,have depressive symptoms,lack of exercise,elevated blood pressure,dyslipidemia,and score higher on core knowledge of chronic diseases are prone to coronary heart disease.

Intervention Effect of New Chinese Herbal Prescription Selected by Data Mining Against Decreased Ovarian Reserve in Rats / 中国实验方剂学杂志

Objective:To select and evaluate new Chinese herbal prescription for the treatment of decreased ovarian reserve （DOR） and its appropriate dosage. Method:The literature concerning the treatment of DOR with traditional Chinese medicine （TCM） was retrieved from such databases as Chinese Journal Full-text Database， Wanfang Data Knowledge Service Platform， and Chongqing Weipu Database for Chinese Technical Periodicals （VIP）， based on which a database was established using the Traditional Chinese Medicine Inheritance Support System （TCMISS） V2.5. The data mining was then carried out to obtain the core combinations of Chinese herbs and new Chinese herbal prescription combinations， followed by the determination of the new Chinese herbal prescription by expert group discussion for experiment evaluation. The female SD rats were divided into the normal group， DOR model group， Kuntai capsule group， and low-， medium-， and high-dose new Chinese herbal prescription groups， with 12 rats in each group. Rats in the Kuntai capsule group and low-， medium-， and high-dose new Chinese herbal prescription groups were treated with Kuntai capsule solution （0.5 g·kg^-1 determined according to the dosage in the instruction） and 3.037 5， 6.075， and 9.12 g·kg^-1 new Chinese herbal prescription， respectively. After 21 days， the estrous cycle was observed by vaginal exfoliated cell smear， and the ovarian structure was observed by hematoxylin-eosin （HE） staining. The serum anti-mullerian hormone （AMH）， follicle stimulating hormone （FSH）， luteinizing hormone （LH）， and estrogen （E₂） contents as well as the reactive oxygen species （ROS）， malondialdehyde （MDA）， and glutathione （GSH） levels and superoxide dismutase （SOD）， catalase （CAT）， and glutathione peroxidase （GSH-Px） activities in ovary were detected using biochemical methods. Result:The new Chinese herbal prescription subjected to experimental evaluation was composed of 11 Chinese herbs， namely Rehmanniae Radix Praeparata 20 g， Cervi Cornus Colla 12 g， Lycii Fructus 20 g， Corni Fructus 12 g， Albiziae Cortex 9 g， Nelumbinis Plumula 3 g， Salviae Miltiorrhizae Radix et Rhizoma 20 g， Astragali Radix 30 g， Atractylodis Macrocephalae Rhizoma 12 g， Dioscoreae Rhizoma 30 g， and Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle 6 g. Compared with the model group， the Kuntai capsule group and medium- and high-dose new Chinese herbal prescription groups exhibited significantly improved estrous cycle and follicular development， elevated serum AMH and E₂ and ovarian GSH （<italic>P</italic><0.05）， decreased serum FSH and LH （<italic>P</italic><0.05） and ovarian ROS and MDA （<italic>P</italic><0.05）， and enhanced SOD， CAT， and GSH-Px activities （<italic>P</italic><0.05）. There were no significant differences in the above-mentioned indexes between the Kuntai capsule group and the middle- and high-dose new Chinese herbal prescription groups， but the estrous cycle and follicular development were better in the latter two groups. Conclusion:The new Chinese herbal prescription screened by data mining is able to enhance ovarian antioxidation， promote follicular development， ameliorate serum hormone and estrous cycle， and effectively improve ovarian reserve function in DOR rats. The medium dose （6.075 g·kg^-1） has been proved optimal.
