Ulcerative colitis is a chronic relapsing inflammatory bowel disease. Modern research indicates that immune dysregulation resulting from disruptions in circadian rhythm is closely associated with its pathogenesis. Both Western chronomedicine and traditional Chinese medicine（TCM）" treatment based on temporal factors" emphasize the temporal relationship between natural rhythms and human physiology and pathology. The " midnight-noon and ebb-flow " theory represents the concrete application and deepening of TCM " treatment based on temporal factors" within the realm of chronomedicine. This article correlates the onset time of ulcerative colitis with specific periods in the " midnight-noon and ebb-flow"theory：the Mao period（05：00-07：00），when the yangming large intestine meridian of hand is dominant； the Si period（09：00-11：00），when the taiyin spleen meridian of foot is dominant； and the You period（17：00-19：00），when the shaoyin kidney meridian of foot is dominant. According to this perspective，if the disease manifests during the Mao period，the pathogenesis is attributed to dampnessheat accumulation and disorder of qi and blood. Treatment should focus on clearing heat，resolving dampness，and harmonizing qi and blood，using modified formulas such as Shaoyao Decoction or Baitouweng Decoction. If it occurs during the Si period，the pathogenesis involves spleen deficiency with dampness obstruction and disharmony of qi and blood. Treatment should focus on strengthening the spleen，eliminating dampness，and restoring qi and blood，using modified formulas such as Huangya Decoction or Shenling Baizhu Powder. If it presents during the You period，the pathogenesis is characterized by fire failing to warm earth，and consumption resulting in qi and blood leakage. Treatment should focus on warming the kidney and spleen，and securing qi and blood，using modified formulas such as Sishen Pill or Tianhun Decoction. In addition to oral administration of Chinese herbal medicine，comprehensive therapies including acupuncture，herbal enemas，and acupoint application can provide novel insights for the clinical diagnosis and treatment of ulcerative colitis.

Objective To construct prostate cancer(PCa)prediction models based on machine learning algorithms, so as to improve the accuracy of early diagnosis of PCa. Methods A retrospective analysis was performed on the clinical data of 504 patients who underwent prostate biopsy at our hospital during Jan. 2020 and Nov. 2024. Patients' age, body mass index(BMI), history of hypertension, diabetes and smoking, total prostate-specific antigen(tPSA), free prostate-specific antigen(fPSA), f/tPSA, prostate volume(PV), neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio(NLR), Prostate Imaging Reporting and Data System(PI-RADS)score, digital rectal examination(DRE)results, and pathological findings were collected. The patients were divided into the training and testing sets at a ratio of 7:3. Ten early diagnosis prediction models of PCa were constructed using 10 supervised machine learning algorithms. Model performance was evaluated and validated using metrics including area under the receiver operating characteristic curve(AUC), accuracy, sensitivity, specificity, calibration curves, and decision curve analysis(DCA). SHAP analysis was used to interpret the models, and to clarify the importance of each feature and the basis for model decisions. Results All models showed good predictive value, with the gradient boosting machine(GBM)model performing the best(AUC=0.905, accuracy=84.1%, sensitivity=90.2%, specificity=80.0%). Calibration curves indicated good calibration and fitting of the GBM model, while DCA demonstrated favorable clinical net benefits. SHAP analysis identified the most significant features affecting PCa occurrence in descending order:tPSA, f/tPSA, PIRADS score, PV, age, and DRE. Conclusion The GBM model exhibits the optimal performance among the 10 models. The importance of features for predicting the occurrence of PCa, from the highest to the lowest, is as follows:tPSA, f/tPSA, PIRADS score, PV, age, and DRE.

In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.
