Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective To explore the genetic polymorphism and mutation rate of 36 Y-STR loci in Sichuan Han population and provide basic data for their forensic applications.Methods Blood samples were collected from 307 unrelated male individuals and 367 father-son pairs in Sichuan Han population using FTA blood sampling cards.The Y41SE-v1.2 kit was used to type 36 Y-STR loci,and the population genetic parameters and mutation rates of each locus were calculated.The genetic relationship between Sichuan Han population and other ethnic populations was analyzed in combination with 19 other populations in China.Results A total of 79 mutations were observed in 36 Y-STR loci in 367 father-son pairs of Sichuan Han population,with an average mutation rate of 6.00×10-3.There were 74(93.67%)one-step mutations and 5(6.33%)multi-step mutations.A total of 383 alleles were found at 36 Y-STR loci in 307 Sichuan Han males.The number of alleles at each locus ranged from 5(0.016 29)to 56(0.182 41),GD ranged from 0.100 02(DYS645)to 0.959 99(DYS385),and 306 haplotypes were found.The HD,DC and HMP values were 0.999 973,99.67%and 0.003 284,respectively.The results of genetic distance(Fst)analysis showed that the Sichuan Han population had the closest genetic distance with the Chongqing Han population(0.000 9)and the furthest genetic distance with the Xinjiang Mongolian group(0.032 0).The MDS based on genetic distance was basically consistent with the results of cluster analysis.Conclusion The 36 Y-STR loci have high genetic polymorphism in the Sichuan Han population.The study data can provide data support for the construction of the Y-STR database in this region,and also provide basic genetic information for forensic investigation and population genetics research.

Objective Explore the feasibility and accuracy of using deep learning techniques for gender inference in panoramic dental radiography images of Chinese Han population.Methods A total of 10,600 OPG images from Han individuals aged 18 to 70(5,300 males and 5,300 females)were collected and randomly divided into training set,validation set,and test set in an 8:1:1 ratio.MobileNetV2,Swin Transformer Small,and Swin Transformer Tiny models were trained,and the classification performance of the models was evaluated and visually displayed using accuracy,F1 score,and Grad-CAM algorithm.Results The accuracy of MobileNetV2,Swin Transformer Small,and Swin Transformer Tiny models was 97.57%,95.13%,and 96.28%respectively,with MobileNetV2 model showing the best overall performance.The Grad-CAM algorithm revealed that male OPG images mainly focused on the left and right mandibular branches and alveolar bone,while female OPG images mainly focused on the maxillary sinus,left mandibular branch,and posterior alveolar bone.Conclusion This study demonstrates that the gender inference model based on deep learning techniques for OPG images of Chinese Han population has high accuracy and generalization ability,providing a new approach for forensic gender determination in forensic medicine.

Objective:To investigate the expressions of CC chemokine receptor 3 (CCR3) and CC chemokine 5 (CCL5) in serum of patients with non-small cell lung cancer (NSCLC) and their predictive value for recurrence and metastasis after surgery.Methods:The clinical data of 90 NSCLC patients (NSCLC group) who underwent surgery in Rugao People's Hospital from January 2017 to December 2020 were retrospectively analyzed. At the same time, 95 healthy people who underwent physical examination during the same period were selected as the healthy control group. The levels of serum CCR3 and CCL5 in the two groups were detected by enzyme-linked immunosorbent assay. After a 2-year postoperative follow-up, the NSCLC patients were recorded for recurrence and metastasis after surgery. Multivariate logistic regression analysis was used to identify the independent factors affecting patients' recurrence and metastasis after surgery. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of CCR3 and CCL5 levels for patients' recurrence and metastasis after surgery.Results:The levels of CCR3 and CCL5 in NSCLC group were higher than those in the healthy control group [(290±36) pg/ml vs. (183±23) pg/ml; (15.7±3.1) pg/ml vs. (6.2±1.2) pg/ml], and the differences were statistically significant ( t values were 24.02 and 27.24, both P < 0.001). The incidence of recurrence and metastasis after surgery in NSCLC group was 34.44% (31/90). The levels of CCR3 and CCL5 in patients with recurrence and metastasis were higher than those in patients without recurrence and metastasis [(315±39) pg/ml vs. (276±35) pg/ml; (17.5±3.4) pg/ml vs. (14.7±2.9) pg/ml], and the differences were statistically significant ( t values were 4.87 and 4.04, both P < 0.001). The result of univariate analysis showed that the proportions of patients with stage Ⅲ A, poorly differentiation and lymph node metastasis in patients with recurrence and metastasis were higher than those in patients without recurrence and metastasis (all P < 0.05). Multivariate logistic regression analysis showed that TNM stage ( OR = 2.587, 95% CI 1.509-4.434), CCR3 level ( OR = 2.215, 95% CI 1.354-3.623) and CCL5 level ( OR = 2.343, 95% CI 1.193-4.598) were independent factors affecting patients' recurrence and metastasis after surgery (all P < 0.05). ROC curve analysis showed that the areas under the curve (AUC) of CCR3, CCL5 and combination of the two in predicting NSCLC patients' recurrence and metastasis after surgery were 0.710, 0.684 and 0.854. Conclusions:The abnormal high expressions of CCR3 and CCL5 in the serum of NSCLC patients are independent risk factors for recurrence and metastasis after surgery. The combined detection of CCR3 and CCL5 can effectively predict the recurrence and metastasis of patients after surgery.
