Objective To compare and analyze the difference of cardiopulmonary reserve function of phlegm-dampness and peaceful constitutions. Methods A total of 102 cases were selected for the physi-cal examination in Air Service Department of Northern Theater Air Force Hospital,and divided into a phlegm-dampness constitution group of 50 and a peaceful constitution group of 52 according to their traditional Chinese medicine constitution. Both groups underwent the cardiopulmonary exercise testing (CPET),and the cardiopulmonary reserve function parameters such as the peak exercise load,peak metabolic equivalent,peak kilogram oxygen uptake,and peak oxygen pulse rate were compared be-tween the 2 groups. Results There was no significant difference between the 2 groups in age,as well as the history of smoking and drinking(P>0.05). Moreover,the average body mass index,neck circum-ference,heart rate reserve,and peak ventilation of the phlegm-dampness constitution group were signif-icantly higher than the peaceful constitution group,while the average peak exercise load,peak meta-bolic equivalent,peak heart rate,peak oxygen pulse,and peak kilogram oxygen uptake were signifi-cantly lower than the latter group(P<0.05). Conclusions Compared with the people of peaceful constitu-tion,those of phlegm-dampness have lower cardiopulmonary reserve function. Therefore,early physical intervention should be conducted to help them to get into a healthy lifestyle.

Objective To establish a universally applicable logistic risk prediction model for diabetes mellitus type 2(T2DM)in the middle-aged and elderly populations based on the results of a Meta-analysis,and to validate and confirm the efficacy of the model using the follow-up data of medical check-ups of National Basic Public Health Service.Methods Cohort studies evaluating T2DM risks were identified in Chinese and English databases.The logistic model utilized Meta-combined effect values such as the odds ratio(OR)to derive β,the partial regression coefficient,of the logistic model.The Meta-combined incidence rate of T2DM was used to obtain the parameter α of the logistic model.Validation of the predictive performance of the model was conducted with the follow-up data of medical checkups of National Basic Public Health Service.The follow-up data came from a community health center in Chengdu and were collected between 2017 and 2022 from 7 602 individuals who did not have T2DM at their baseline medical checkups done at the community health center.This community health center was located in an urban-rural fringe area with a large population of middle-aged and elderly people.Results A total of 40 cohort studies were included and 10 items covered in the medical checkups of National Basic Public Health Service were identified in the Meta-analysis as statistically significant risk factors for T2DM,including age,central obesity,smoking,physical inactivity,impaired fasting glucose,a reduced level of high-density lipoprotein cholesterol(HDL-C),hypertension,body mass index(BMI),triglyceride glucose(TYG)index,and a family history of diabetes,with the OR values and 95% confidence interval(CI)being 1.04(1.03,1.05),1.55(1.29,1.88),1.36(1.11,1.66),1.26(1.07,1.49),3.93(2.94,5.24),1.14(1.06,1.23),1.47(1.34,1.61),1.11(1.05,1.18),2.15(1.75,2.62),and 1.66(1.55,1.78),respectively,and the combined β values being 0.039,0.438,0.307,0.231,1.369,0.131,0.385,0.104,0.765,and 0.507,respectively.A total of 37 studies reported the incidence rate,with the combined incidence being 0.08(0.07,0.09)and the parameter α being-2.442 for the logistic model.The logistic risk prediction model constructed based on Meta-analysis was externally validated with the data of 7 602 individuals who had medical checkups and were followed up for at least once.External validation results showed that the predictive model had an area under curve(AUC)of 0.794(0.771,0.816),accuracy of 74.5%,sensitivity of 71.0%,and specificity of 74.7% in the 7 602 individuals.Conclusion The T2DM risk prediction model based on Meta-analysis has good predictive performance and can be used as a practical tool for T2DM risk prediction in middle-aged and elderly populations.

Objective:To translate the Illness Identity Questionnaire (IIQ) into Chinese and test its reliability and validity.Methods:The English version of IIQ was translated into Chinese and back-translated according to the Brislin model. The item of the Chinese version was determined after cross-cultural adaptation and pre-experiment. A total of 368 patients with IBD treated in the First Affiliated Hospital with Nanjing Medical University from September 2022 to March 2023 were selected for a questionnaire survey to evaluate the reliability and validity of the questionnaire.Results:The Chinese version of IIQ contained 24 items in four dimensions. Four common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.025%. Confirmatory factor analysis showed that each fitting index of the modified model was within the acceptable range. The Cronbach's α coefficients of rejection, acceptance, engulfing, and enrichment in Chinese IIQ were respectively 0.780, 0.800, 0.921, and 0.917. The split-half reliability coefficients were 0.824, 0.818, 0.943, and 0.929; the retest reliability coefficients were 0.695, 0.667, 0.725, and 0.572, respectively.Conclusions:The Chinese version of IIQ is reliable and valid and can be used to assess illness identity in patients with chronic diseases.
