Objective:To investigate Beijing residents′ preferences, marginal willingness to pay (mWTP), and utilization probabilities regarding the traditional Chinese medicine (TCM) health management services provided by community health service institutions, and to provide references for promoting the application and dissemination of TCM health management at the grassroots level.Methods:A questionnaire was designed based on a discrete choice experiment involving six attributes influencing residents′ utilization of TCM health management services: medical insurance coverage, technical effectiveness, service provider, physician seniority, treatment modality, and individual average out-of-pocket cost. A multi-stage stratified random sampling method was used to select 800 residents from three community health service institutions across three administrative districts of Beijing. The survey was conducted from November to December 2024. A mixed logit model was employed to analyze the factors influencing service utilization preferences, mWTP, and utilization probabilities.Results:A total of 733 valid questionnaires were included in the analysis. All six attributes significantly influenced residents′ service utilization preferences ( P<0.05). Residents showed stronger preferences for services with lower individual average out-of-pocket costs ( β=-0.214), combination therapies involving both internal medication and external treatments ( β=0.314), provision by senior-level professionals ( β= 0.522), fixed service providers ( β=0.851), longer treatment courses with better efficacy ( β=1.323), and services covered by medical insurance ( β=1.843). When services were covered by insurance, featured longer courses with better efficacy, and involved fixed service providers, the probability of service utilization increased to 76.52%. Heterogeneity in service utilization preferences was observed across different ages, genders and chronic health conditions ( P<0.05). Conclusions:Medical insurance coverage, technical efficacy and doctor service continuity are the most influential factors affecting residents′ service utilization. Optimizing the combination of TCM health management service attributes can enhance residents′ willingness to utilize these services. It is recommended to develop multi-tiered medical security strategies, selectively include high-value TCM health management services into insurance coverage, strengthen physician-patient trust, and design differentiated " disease prevention" service packages for residents with different characteristics to improve overall population health.

Objective To investigate serum total prostate special antigen(tPSA),complexed prostate special antigen(cPSA)and cPSA/tPSA ratio(C/T) in the differential diagnosis of benign prostate hyperplasia(BPH)and prostate cancer(PCa).Methods A total of 184 serum samples from hospital outpatient and inpatient were collected from May 2009 to December 2015,and which were divided into three groups including other diseases 68 patients,benign prostate hyperplasia(BPH group)80 patients,prostate cancer (PCa group)36 patients.Chemiluminescence immunoassay was used to detect the concentration of tPSA and cPSA,and the C/T ratio were calculated in the study.Results The tPSA,ePSA levels and C/T ratio were significant different from patients with PCa,BPH and other diseases group(P＜0.01).Compared with BPH group(r=0.661),the tPSA and cPSA levels have a higher relativity in PCa group(cPSA=0.708 × tPSA-0.219,r=0.956).While when tPSA level ranges 4.0-10.0 ng/mL),no significant difference of tPSA,cPSA levels and C/T ratio were found in these 3 groups(P＞0.05).Conclusion Combined detection of serum tPSA,cPSA and C/T,making importance in the differential diagnosis of BPH and PCa.
