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.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

Objective:To explore the experience and learning curve of single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach.Methods:Clinical data of 138 patients undergoing single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via oral vestibular approach from Sep. 2019 to Dec. 2021 in the Department of Thyroid and Breast Surgery of Affiliated Hospital of North Sichuan Medical College were retrospectively analyzed. The cumulative sum (CUSUM) method and best-fit curve analysis were used to compare the differences in each index such as operative time, intraoperative bleeding, number of lymph nodes cleared in the central region and postoperative related complications at various stages of the learning curve.Results:All 138 patients underwent single-line suspension rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach, and one patient was converted to open surgery due to large intraoperative bleeding in the mass. There were 14 males and 124 females, mean age (36.07±8.49) years (20-55 years), thyroid tumor size (7.74±6.49) mm (2.4-50mm), 5 cases underwent Subtotal thyroidectomy, 129 cases underwent Unilateral lobectomy + lymph node dissection in the middle region, and 4 cases total thyroidectomy + central zone lymph node dissection. The number of surgical cases corresponding to the apex of the CUSUM learning curve was 45, and the learning curve was divided into two stages: the learning improvement stage (1-45 cases) and the mastery stage (46-138 cases). The operative time, intraoperative bleeding, postoperative hospital stay, and chin numbness were all lower in the proficiency period than in the learning and training period ( P<0.05), and the number of lymph nodes cleared in the central region was larger than that in the learning and improvement stage ( P<0.05), while the differences in other indexes between the two stages were not statistically significant ( P>0.05) . Conclusion:The single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach has clinical application value and is worth promoting, and the number of surgical cases to be accumulated to master this technique is 45.

BACKGROUND:Osteoarthritis is one of the most common senile chronic degenerative diseases in China.Due to its complex pathogenesis and cellular molecular communication pathways,there is currently no effective method to slow down the progression of osteoarthritis.Studies have found that transforming growth factor-β is one of the key factors in the maintenance and regulation of joint stability and plays a significant role in the formation of early joints,as well as the development of bone and cartilage,and the remodeling of joints at various stages. OBJECTIVE:To review the regulatory role of the transforming growth factor-β subfamily in the occurrence and development of osteoarthritis,both domestically and internationally in recent years,to analyze the impacts it has at different stages of osteoarthritis,and to explore the potential application prospects of transforming growth factor-β in the clinical treatment of osteoarthritis,with a view to informing clinical treatment protocols.. METHODS:The relevant articles were searched by computer from CNKI Database and PubMed Database.The search terms were"osteoarthritis,transforming growth factor,signaling pathway,bone remodeling,cartilage degeneration,angiogenesis,treatment"in Chinese and English,respectively.Finally,57 articles were included for review. RESULTS AND CONCLUSION:The pathogenesis of osteoarthritis remains a subject of ongoing exploration with no unified consensus.Numerous studies highlight the close correlation between osteoarthritis and cytokines,focusing on the transforming growth factor-β superfamily as a pivotal mechanism and therapeutic breakthrough.Transforming growth factor-β plays a crucial role in early joint cartilage formation and maintenance,promoting cartilage repair.However,post-joint formation,its protective effect weakens,leading to potential destructive consequences.This dual regulatory role is a current clinical treatment focus,necessitating further research to delineate its application scope for standardized protocols.Highly active transforming growth factor-β participates in the regulation of bone cells,osteoblasts,and osteoclasts under mechanical stress,and intervenes in the subsequent remodeling of bone microstructure.Specific inhibitors present potential targeted therapeutics,yet their safety and efficacy in clinical settings require refinement.Vascular proliferation may serve as a potential disruptive pathway in transforming growth factor-β-mediated cartilage degeneration and subchondral bone remodeling.Abnormal communication pathways can further disrupt the homeostasis of the microenvironment of osteochondral units,thereby accelerating key pathological progressions of osteoarthritis.Research on transforming growth factor-β in osteoarthritic contexts is comprehensive,holding broad clinical application prospects.Drugs related to transforming growth factor-β are in clinical trial phases,but addressing potential impacts on other tissues and precise control of targeted delivery are critical concerns.As research advances,there is optimism for innovative breakthroughs in slowing the progression of osteoarthritis in the future.

Objective:To analyse the clinical efficacy of arthroscopic double-bundle Endobutton fixation of the thin bone channel in the treatment of Rockwood type III-V acromioclavicular joint dislocation.Methods:A total of 34 patients with acromioclavicular joint dislocation, 24 males and 10 females, aged 50.9±11.0 years (range, 21-74 years), who underwent arthroscopic double-bundle Endobutton fixation of the thin bone channel at Zhejiang Province Taizhou Hospital, Wenzhou Medical University, from February 2015 to February 2022 were retrospectively analyzed. There were 24 cases on the left side and 10 cases on the right side. Causes of injury: 23 cases of car accident, 7 cases of fall, 4 cases of falling from height. Rockwood classification: Type III 17 cases, type IV 9 cases, type V 8 cases. The visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, and joint range of motion were used to evaluate shoulder pain and functional improvement.Results:All patients successfully completed the operation and were followed up for an average of 16.6±2.8 months (range, 12-24 months). Postoperative VAS scores were significantly lower compared to preoperative scores ( F=199.408, P<0.001), with the final follow-up VAS score being 1.32±0.47, significantly lower than the preoperative score of 4.71±1.19 ( P<0.001). Postoperative ASES scores were significantly higher compared to preoperative scores ( F=335.838, P<0.001), with the final follow-up ASES score being 88.85±6.41, significantly higher than the preoperative score of 34.76±5.79 ( P<0.001). The Constant-Murley scores of 3 months, 6 months after operation and the last follow-up were 77.79±5.34, 87.40±5.19 and 88.17±4.40, respectively, which were higher than that before operation 37.41±6.52, and the difference was statistically significant ( P<0.05). At the final follow-up, shoulder flexion, adduction, and abduction were 172.9°±6.4°, 59.2°±6.2°, and 59.3°±5.9°, respectively. The coracoclavicular distance was 1.76±0.42 mm, 0.84±0.19 mm, and 0.87±0.18 mm before operation, 3 months after operation, and at the last follow-up, respectively, and the difference was statistically significant ( F=101.160, P<0.001). Whereas, 3 months postoperative and the final follow-up were smaller than the preoperative ones, and the difference was statistically significant ( P<0.05). All incisions healed in one stage, and there was no vascular or nerve injury, internal fixation infection, coracoid process or clavicle bone tunnel fracture, or internal fixation loosening or breakage. Conclusion:Arthroscopic double-bundle Endobutton fixation with thin bone channel for the treatment of Rockwood type III-V acromioclavicular joint dislocation can improve shoulder function and reduce pain, with high surgical safety.

Objective To analyze the individualized CTV-to-PTV margin dose and positioning errors in radiotherapy for esophageal cancer for improving the treatment accuracy while meeting dose requirements.Methods Fifty-four esophageal cancer patients admitted to Sun Yat-sen University Cancer Center at Huangpu District from June 2021 to June 2022 were enrolled.All of the patients underwent CBCT scans in each fraction,and a total of 1283 CBCT images were collected.The image registration between CBCT image before radiotherapy and planning CT image was carried out to obtain errors in vertical(VRT),longitudinal(LNG),lateral(LAT),Roll,Pitch,and YAW directions.The mean values of six-dimensional positioning errors in the first 5 fractions were calculated,and the results were compared with the total fractional errors using the single sample t-test method for determining the differences.The CTV-to-PTV margin was calculated with the formula(margin=2.5∑+0.7δ),and the calculated margins were divided into 5 groups:Group A(5 mm expansion in all directions),Group B(7.9 mm expansion in LAT direction,and 5 mm expansion in other directions),Group C(11.03 mm expansion in LNG direction,and 5 mm expansion in the other directions),Group D(6.36 mm expansion in VRT direction,and 5 mm expansion in the other directions),and Group E(7.9 mm expansion in LAT direction,11.03 mm expansion in LNG direction,and 6.36 mm expansion in VRT direction).Simulation planning was conducted for 10 patients.Results The proportions of differences between the mean values of six-dimensional errors in the first 5 fractions and the total fractional errors in 54 patients were analyzed.There was no significant difference in 192 out of the 324 directions in 54 patients,accounting for 59.26%(P>0.05).Among them,the LAT,LNG,VRT,Pitch,Roll and YAW directions accounted for 64.81%,57.41%,51.85%,64.81%,57.41%and 59.26%of the total cases.The calculated CTV-to-PTV margin was 7.90,11.03 and 6.36 mm in LAT,LNG and VRT directions.The statistical analysis showed that the differences in the coverage rates of organs-at-risk and target areas among the 5 groups of CTV-to-PTV margins were trivial(P>0.05).Conclusion Using the positioning errors in the first 5 fractions of radiotherapy for esophageal cancer to predict subsequent positioning errors is feasible.The reasonable individualized margin in radiotherapy for esophageal cancer can reduce the inter-fractional off-target rate without increasing the dose delivered to organs-at-risk.The study provides a reference for the target volume margin of esophageal cancer and an important basis for precision treatment.
