Investigator initiated trial （IIT） represents a primary format for clinical research in traditional Chinese medicine （TCM）. As key implementation sites for TCM-based IIT targeting malignant tumors， western medicine institutions often face unique challenges in conducting such studies， which limit their feasibility and standardization. This paper reviews the registration status of TCM-based IIT for malignancies conducted in western medical institutions and analyzes key difficulties， including complex project initiation and management processes， limited TCM knowledge and skills among western medicine physicians， and relatively low patient acceptance of TCM. From a practical perspective， the study proposes several optimization strategies. These include improving the review and management mechanisms of TCM-related IIT within western medical institutions， establishing multidisciplinary clinical research teams that integrate TCM and western medicine， and enhancing investigators' training in TCM theory and clinical skills. Additionally， the study suggests standardizing IIT operational procedures， objectifying the collection of TCM diagnostic information， refining subject recruitment methods， and increasing TCM involvement in patient follow-up and management. These investigator-oriented， TCM-featured， and operable strategies aim to promote the high-quality development of TCM-based IIT in western medicine institutions and enhance the clinical application of TCM.

According to the theory of cancer toxin pathogenesis， tumors are complex syndromes centered on cancer toxin， characterized by multiple time points and locations， interwoven pathogenic toxins， and a combination of deficiency and excess. Postoperative recurrence of colorectal cancer is a dynamic spatiotemporal process. In this paper， the core pathogenesis of postoperative recurrence of colorectal cancer， namely "deficiency of spleen qi， with damp-heat stasis toxin"， has been discussed based on spatiotemporal evolution of cancer toxin. It is suggested that spleen qi depletion leading to the proliferation of cancer toxin represents the temporal characteristic of postoperative recurrence， while the stasis of damp-heat facilitating the aggregation and spread of cancer toxin refelct its spatial pattern. This paper has constructed a holistic spatiotemporal prevention and treatment strategy according to different stages before and after recurrence. Before recurrence， the focus is on prevention， and it is suggested to rectify the healthy qi and fortify spleen， clear heat and resolve dampness， unblock collaterals and remove toxin. After recurrence， the focus should be on treatment， and the strategy is combating cancer and removing toxin， breaking the blood to eliminate disease， regulating and tonifying the zang-fu （脏腑） organs.

To explore the feasibility of using UAV-LiDAR for measuring the leaf area index (LAI) of crop canopies, we employed UAV-LiDAR to scan sugarcane canopies during the tillering and elongation stages, acquiring canopy point cloud data. Subsequently, features such as average row height, projected row area, point cloud density at different canopy layers, and the ratios between these parameters were extracted. Three feature selection methods-partial least squares regression (PLSR), XGBoost feature importance (XGBoost-FI), and random forest-recursive feature elimination (RF-RFE)-were adopted to evaluate and identify the optimal input variables for modeling. With these selected variables, LAI inversion models were developed based on random forest (RF) and adaptive boosting (AdaBoost) algorithms, and their performance was assessed. Among the extracted features, the projected row area S_p and the total row point count C_total exhibited strong correlations with LAI, with correlation coefficients of 0.73 and 0.72, respectively. The AdaBoost-based LAI inversion model, using the projected row area S_p, average height H_avg, mid-layer point cloud density C_m, and total row point count C_total as input variables, achieved the best performance, with a coefficient of determination (R_v²) of 0.713 and a root mean square error (RMSE_v) of 0.25 on the validation set. This study provides an effective method for high-throughput acquisition of LAI in field crops, offering valuable scientific support for sugarcane field management and breeding efforts.

Objective To establish a set of regional evaluation index system for clinical medicine disciplines,and to provide a reference tool for evaluating the effectiveness of its construction.Methods Based on relevant policies and literature research,Delphi expert consultation method and analytic hierarchy process were used to determine the index system and assign corresponding weights.The index system was used to conduct field analysis of 10 clinical disciplines in a district of Shenzhen,and the total score of each discipline was calculated by weighted summing method and spearman correlation analysis was used to verify the validity of the evaluation results.Results A set of evaluation index system including 5 first-level indicators,16 second-level indicators and 54 third-level indicators was formed and the weights of all levels of indicators were quantified,which could truly reflect the level of regional clinical discipline construction.Conclusion The established subject evaluation index system has high initiative,authority and coordination of expert consultation.The results of empirical evaluation have a certain degree of differentiation,and are highly correlated with the ranking results of experts,and have strong feasibility.
