OBJECTIVE: To construct an integrated management model for early screening and diagnosis of PCa based on the Innovative Care for Chronic Conditions Framework (ICCC) and the 1+1 contract-based tiered diagnosis and treatment system (TDTS) in China. METHODS: Based on the 1+1 contract-based TDTS platform, we conducted PCa screening for the male residents aged 60 years and above during health check-ups in Pujin Community Health Center from January 1, 2023 to December 31, 2023. For those with abnormal total prostate-specific antigen (tPSA) ≥ 4 μg/L, we promptly referred them to higher-level hospitals for further diagnosis and treatment via the two-way referral green channel platform and information sharing service using the 1+1 contract model. We further analyzed the relevant data on screening and diagnosis. RESULTS: A total of 4 080 males aged 71.39±5.059 years received PCa screening from January to December 2023. PSA screening was performed in 43.96% of the male residents, revealing 654 cases of PSA abnormality, with a PSA positivity rate of 16.03%, which was higher than that found in the previous large-scale PCa screenings in other regions of China. Among the males with PSA abnormality, 292 (44.65%) expressed their willingness for medical referral, while the others did not seek further medical attention for reasons of being asymptomatic, low awareness of the disease, no accompany for medical visits, and concerns about further costs of diagnosis and treatment. Prostate biopsy was recommended to 154 cases after further examinations, which was accepted by 92 (59.74%). Fifty-eight cases were diagnosed with Pa, and thedetection rate reached 63.04%. CONCLUSION The integrated management model for PSA examination-based early screening and diagnosis of PCa using the 1+1 contract-based TDTS platform is plays a significant role in enhancing people's awareness and knowledge of PCa and improving the early detection rate of the malignancy.

Cancer is characterized by abnormal cell proliferation. Cyclins and cyclin-dependent kinases (CDKs) have been recognized as essential regulators of the intricate cell cycle, orchestrating DNA replication and transcription, RNA splicing, and protein synthesis. Dysregulation of the CDK pathway is prevalent in the development and progression of human cancers, rendering cyclins and CDKs attractive therapeutic targets. Several CDK4/6 inhibitors have demonstrated promising anti-cancer efficacy and have been successfully translated into clinical use, fueling the development of CDK-targeted therapies. With this enthusiasm for finding novel CDK-targeting anti-cancer agents, there have also been exciting advances in the field of targeted protein degradation through innovative strategies, such as using proteolysis-targeting chimera, heat shock protein 90 (HSP90)‍-mediated targeting chimera, hydrophobic tag-based protein degradation, and molecular glue. With a focus on the translational potential of cyclin- and CDK-targeting strategies in cancer, this review presents the fundamental roles of cyclins and CDKs in cancer. Furthermore, it summarizes current strategies for the proteasome-dependent targeted degradation of cyclins and CDKs, detailing the underlying mechanisms of action for each approach. A comprehensive overview of the structure and activity of existing CDK degraders is also provided. By examining the structure‍‒‍activity relationships, target profiles, and biological effects of reported cyclin/CDK degraders, this review provides a valuable reference for both CDK pathway-targeted biomedical research and cancer therapeutics.

Objective: To investigate the subclinical eating disorders among college students and to analyze associated factors, so as to provide a basis for the prevention and treatment of eating disorders among adolescents. Methods: From November to December 2023, a total of 5 201 college students were selected by stratified random cluster sampling from one undergraduate college and one specialized college in Yangzhou City, Jiangsu Province. Data on general information, subclinical eating disorders, body image perception, depressive symptoms, anxiety symptoms, and mental health literacy were collected using questionnaires. The Chisquare test was used to compare the detection rates of subclinical eating disorders between groups, and binary Logistic regression was employed to analyze associated factors. Results: The detection rate of subclinical eating disorders among college students was 16.0%. Binary Logistic regression analysis showed that the prevalence of subclinical eating disorders among college students was higher in the following categories:being in a relationship (OR=1.22, 95%CI=1.04-1.44), being overweight and obese (OR=2.75, 3.82, 95%CI=2.24-3.38, 2.89-5.06), overestimation of body shape (OR=2.04, 95%CI=1.68-2.49), being in a depressive state (OR=2.53, 95%CI=1.99-3.21), experiencing anxiety (OR=2.63, 95%CI=2.16-3.20), and having substandard mental health literacy (OR=1.37, 95%CI=1.11-1.70). Conversely, low body weight (OR=0.15, 95%CI=0.10-0.22) and underestimation of body shape (OR=0.37, 95%CI=0.27-0.51) were associated with a lower risk (P<0.05). Conclusions The detection rate of subclinical eating disorders among college students is high, and it is associated with relationship status, body mass index classification, body shape perception, depressive and anxiety symptoms, and mental health literacy. Comprehensive interventions should be implemented to improve the subclinical eating disorders and promote the physical and mental health of college students.
