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.

Definitive treatment of lung cancer with radiotherapy is challenging, as respiratory motion and anatomical changes can increase the risk of severe off-target effects during radiotherapy. Online adaptive radiotherapy (ART) is an evolving approach that enables timely modification of a treatment plan during the interfraction of radiotherapy, in response to physiologic or anatomic variations, aiming to improve the dose distribution for precise targeting and delivery in lung cancer patients. The effectiveness of online ART depends on the seamless integration of multiple components: sufficient quality of linear accelerator-integrated imaging guidance, deformable image registration, automatic recontouring, and efficient quality assurance and workflow. This review summarizes the present status of online ART for lung cancer, including key technologies, as well as the challenges and areas of active research in this field.

OBJECTIVE: To quantitatively evaluate the accuracy of data obtained from liquid-interference surfaces using an intraoral 3D scanner (IOS) integrated with a compressed airflow system, so as to provide clinical proof of accuracy for the application of the compressed airflow system-based scanning head in improving data quality on liquid-interference surfaces. METHODS: The study selected a standard model as the scanning object, adhering to the "YY/T 1818-2022 Dental Science Intraoral Digital Impression Scanner" guidelines, a standard that defined parameters for intraoral scanning. To establish a baseline for accuracy, the ATOS Q 12M scanner, known for its high precision, was used to generate true reference values. These true values served as the benchmark for evaluating the IOS performance. Building on the design of an existing scanner, a new scanning head was developed to integrate with a compressed airflow system. This new design aimed to help the IOS capture high-precision data on surfaces where liquid-interference, such as saliva, might otherwise degrade scanning accuracy. The traditional scanning method, without airflow assistance, was employed as a control group for comparison. The study included five groups in total, one control group and four experimental groups, to investigate the effects of scanning lens obstruction, airflow presence, liquid media, and the use of the new scanning head on scanning process and accuracy. Each group underwent 15 scans, generating ample data for a robust statistical comparison. By evaluating trueness and precision in each group, the study assessed the impact of the compressed airflow system on the accuracy of IOS data collected from liquid-interference surfaces. Additionally, we selected Elite and Primescan scanners as references for numerical accuracy values. RESULTS: The scanning accuracy on liquid-interference surfaces was significantly reduced in terms of both trueness and precision [Trueness: 18.5 (6.5) vs. 38.0 (6.7), P < 0.05; Precision: 19.1 (8.5) vs. 31.7 (15.0), P < 0.05]. The use of the new scanning head assisted by the compressed airflow system significantly improved the scanning accuracy [Trueness: 22.3(7.6) vs. 38.0 (6.7), P < 0.05; Precision: 25.8 (9.6) vs. 31.7 (15.0), P < 0.05]. CONCLUSION The scanning head based on the compressed airflow system can assist in improving the accuracy of data obtained from liquid-interference surfaces by the IOS.

OBJECTIVE: Left ventricular remodeling induced by myocardial ischemia/reperfusion injury (MI/RI) is a common cardiac dysfunction. Accumulating evidence has demonstrated that autophagy plays a vital role in protecting against ventricular remodeling. This study aims to investigate the performance of Compound Danshen Tablets (CDT) in rescuing ventricular remodeling and whether autophagy as the potential mechanism. METHODS: The left anterior descending arteries of rats were temporarily ligated for 30 min to construct the MI/RI model. Ventricular remodeling was induced by reperfusion for 28 d, during which the MI/RI rats were administered CDT (300 mg/kg and 600 mg/kg), atorvastatin (2 mg/kg), and diltiazem (16 mg/kg). Cardiac function and structure were examined by echocardiography. Immunohistochemistry, Masson's trichrome staining, and hematoxylin-eosin (HE) staining were utilized to assess the fibrosis and histological alterations in the heart tissue. The expression of autophagy-related proteins was detected using Western blotting. RESULTS: CDT attenuated the cardiac dysfunction, structural changes, histopathological changes and fibrosis induced by MI/RI. CDT significantly enhanced the level of Beclin1 and microtubule-associated protein 1 light chain 3 beta (LC3β), and reduced p62 levels in MI/RI rats. Moreover, CDT significantly increased the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and inhibited mammalian target of rapamycin (mTOR) phosphorylation. CONCLUSION CDT ameliorated MI/RI-induced ventricular remodeling by activating autophagy and improving autophagic flux via the AMPK/mTOR signaling pathway.

Central nervous system idiopathic inflammatory demyelinating diseases (CNS-IIDD) is an autoimmune disorder characterized by inflammatory demyelination. The disease follows a course of recurrent attacks and remission, with some cases displaying continuous progression, often resulting in disability. The incidence of CNS-IIDD has been increasing, imposing a substantial burden on both patients′ families and society in recent years. A promising strategy for disease management involves the identification of humoral biomarkers to diagnose CNS-IIDD and predict disease attack and progression. Such biomarkers could aid in identifying individuals at high risk of disability, enabling targeted preventive interventions. This study summarizes advancements in the identification of humoral biomarkers and their potential for predicting disease activity and progression to offer novel insights into the management of CNS-IIDD.

ObjectiveTo investigate the ameliorative effect and mechanism of total saponins of Codonopsis Radix （TSC） on learning and memory impairment induced by D-galactose in aging mice. MethodTwenty-four male C57BL/6J mice were randomly assigned into four groups （n=6）： normal group， model group （200 mg·kg^-1 D-galactose）， TSC group （200 mg·kg^-1）， and donepezil group （3 mg·kg^-1）. After one week of pre-treatment， the mice in the model， TSC， and donepezil groups were administrated with corresponding agents for 8 weeks. In the ninth week， the Morris water maze test was performed to assess the learning and memory abilities. Histopathological changes in the brain were evaluated by hematoxylin-eosin （HE） and Nissl staining. Immunohistochemistry was used to detect the expression of nuclear factor kappa-B （NF-κB）， tumor necrosis factor-α （TNF-α）， and brain-derived neurotrophic factor （BDNF） in the brain tissue. The serum levels of glutathione peroxidase （GSH-Px）， catalase （CAT）， superoxide dismutase （SOD）， malondialdehyde （MDA）， TNF-α， interleukin-1β （IL-1β）， and interleukin-18 （IL-18） were measured by enzyme-linked immunosorbent assay， on the basis of which the effects of TSC on neuroinflammation and memory impairment in D-galactose-induced aging mice were assessed. ResultCompared with the normal group， the model group exhibited decreased cognitive function， decreased activities of CAT， SOD， and GSH-Px in the serum （P<0.01）， and upregulated levels of MDA， TNF-α， IL-1β， and IL-18 （P<0.01）. In addition， partial neuronal damage and degeneration were observed in the hippocampus and cortex of the model group， accompanied by downregulated BDNF expression （P<0.05） and upregulated NF-κB and TNF-α expression （P<0.05）. Compared with the model group， TSC alleviated D-galactose-induced cognitive dysfunction， enhanced the activities of CAT， SOD， and GSH-Px （P<0.01）， lowered MDA， TNF-α， IL-1β， and IL-18 levels （P<0.01）， and ameliorated the pathological changes in the hippocampus and cerebral cortex. Additionally， TSC upregulated BDNF expression （P<0.05， P<0.01） and downregulated NF-κB and TNF-α expression （P<0.05， P<0.01） in the hippocampus and cerebral cortex. ConclusionTSC exerts a protective effect on cognitive dysfunction induced by D-galactose in aging mice by inhibiting oxidative stress and inflammation.

Objective To observe the value of augmented reality(AR)navigation system for assisting CT-guided puncture of pulmonary nodules in dog models.Methods Five healthy dogs were selected,and 4 target lung rings were implanted in each dog to build pulmonary nodule models.Deferring to crossover design,CT-guided punctures were performed with or without AR navigation 2 and 4 weeks after successful modeling,respectively,while punctures with AR navigation were regarded as AR group and the others as conventional group,respectively.The time duration of puncturing,the times of CT scanning,of needle adjustment,and the deviation distance between needle pinpoint to the center of pulmonary nodule shown on three-dimensional reconstruction were compared between groups.Results The duration time of puncture in AR group and conventional group was(13.62±5.11)min and(20.16±4.76)min,respectively.In AR group,the times of CT scanning,of needle adjustment,and the deviation distance was 2.40±0.50,2.75±0.44 and(2.94±1.92)mm,respectively,while in conventional group was 3.10±0.64,3.70±0.57 and(4.90±3.38)mm,respectively.The introduction of AR navigation was helpful to shortening the duration of puncture,reducing times of CT scanning and needle adjustment,also decreasing positioning error of needle pinpoint(all P＜0.05).In contrast,the variance of puncture sequences and dogs had no obvious effect on the results(both P＞0.05).Conclusion AR navigation system could improve accuracy and efficiency in CT-guided puncture of pulmonary nodules in dog models.
