This paper outlines the development of artificial intelligence （AI） and its applications in traditional Chinese medicine （TCM） research， and elucidates the roles and advantages of large language models， knowledge graphs， and natural language processing in advancing syndrome identification， prescription generation， and mechanism exploration. Using spleen-stomach diseases as an example， it demonstrates the empowering effects of AI in classical literature mining， precise clinical syndrome differentiation， efficacy and safety prediction， and intelligent education， highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration， a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed， integrating blockchain-based smart contracts， federated learning， and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases， providing feasible pathways and a technical framework for building a high-quality， trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

This paper explores the impacts of accelerated rehabilitation protocols following anterior cruciate ligament reconstruction(ACLR)on bone tunnel enlargement(BTE).While accelerated rehabilitation can shorten the recovery time and improve the knee function,it may increase the risk of BTE.In the early rehabilitation phase after ACLR,excessive early weight-bearing and rapid progression of knee flexion angles should be avoided,along with the proper use of braces.Continuous passive motion is not recommended in the early phase post-ACLR to prevent potential effects on BTE.Further research is needed to investigate the mechanisms of BTE and develop more effective rehabilitation strategies.This will help to select appropriate rehabilitation protocols for patients and balance functional recovery with the risk of BTE,thereby reducing the revision rate and improving postoperative outcomes.

BACKGROUND: Chronic kidney disease (CKD) is associated with common pathophysiological processes, such as inflammation and fibrosis, in both the heart and the kidney. However, the underlying molecular mechanisms that drive these processes are not yet fully understood. Therefore, this study focused on the molecular mechanism of heart and kidney injury in CKD. METHODS: We generated an microRNA (miR)-26a knockout (KO) mouse model to investigate the role of miR-26a in angiotensin (Ang)-II-induced cardiac and renal injury. We performed Ang-II modeling in wild type (WT) mice and miR-26a KO mice, with six mice in each group. In addition, Ang-II-treated AC16 cells and HK2 cells were used as in vitro models of cardiac and renal injury in the context of CKD. Histological staining, immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), and Western blotting were applied to study the regulation of miR-26a on Ang-II-induced cardiac and renal injury. Immunofluorescence reporter assays were used to detect downstream genes of miR-26a, and immunoprecipitation was employed to identify the interacting protein of LIM and senescent cell antigen-like domain 1 (LIMS1). We also used an adeno-associated virus (AAV) to supplement LIMS1 and explored the specific regulatory mechanism of miR-26a on Ang-II-induced cardiac and renal injury. Dunnett's multiple comparison and t -test were used to analyze the data. RESULTS: Compared with the control mice, miR-26a expression was significantly downregulated in both the kidney and the heart after Ang-II infusion. Our study identified LIMS1 as a novel target gene of miR-26a in both heart and kidney tissues. Downregulation of miR-26a activated the LIMS1/integrin-linked kinase (ILK) signaling pathway in the heart and kidney, which represents a common molecular mechanism underlying inflammation and fibrosis in heart and kidney tissues during CKD. Furthermore, knockout of miR-26a worsened inflammation and fibrosis in the heart and kidney by inhibiting the LIMS1/ILK signaling pathway; on the contrary, supplementation with exogenous miR-26a reversed all these changes. CONCLUSIONS Our findings suggest that miR-26a could be a promising therapeutic target for the treatment of cardiorenal injury in CKD. This is attributed to its ability to regulate the LIMS1/ILK signaling pathway, which represents a common molecular mechanism in both heart and kidney tissues.

OBJECTIVES: To investigate the chain mediating role of family care and emotional management in the relationship between social support and anxiety among rural primary school students. METHODS: A questionnaire survey was conducted among students in grades 4 to 6 from four counties in Hunan Province. Data were collected using the Social Support Rating Scale, Family Care Index Scale, Emotional Intelligence Scale, and Generalized Anxiety Disorder -7. Logistic regression analysis was used to explore the influencing factors of anxiety symptoms. Mediation analysis was conducted to assess the chain mediating effects of family care and emotional management between social support and anxiety. RESULTS: A total of 4 141 questionnaires were distributed, with 3 874 valid responses (effective response rate: 93.55%). The prevalence rate of anxiety symptoms among these students was 9.32% (95%CI: 8.40%-10.23%). Significant differences were observed in the prevalence rates of anxiety symptoms among groups with different levels of social support, family functioning, and emotional management ability (P<0.05). The total indirect effect of social support on anxiety symptoms via family care and emotional management was significant (β=-0.137, 95%CI: -0.167 to -0.109), and the direct effect of social support on anxiety symptoms remained significant (P<0.05). Family care and emotional management served as significant chain mediators in the relationship between social support and anxiety symptoms (β=-0.025,95%CI:-0.032 to -0.018), accounting for 14.5% of the total effect. CONCLUSIONS Social support can directly affect anxiety symptoms among rural primary school students and can also indirectly influence anxiety symptoms through the chain mediating effects of family care and emotional management. These findings provide scientific evidence for the prevention of anxiety in primary school students from multiple perspectives.

BACKGROUND:Spine osteoarthritis is a chronic inflammatory disease of the spine,articular ligaments,and tendons,and is the main cause of chronic low back pain.Artificial tiger bone powder has anti-inflammatory and pain-relieving biological effects,so it is expected to provide a new strategy for targeted therapy of spinal osteoarthritis.OBJECTIVE:To investigate the mechanism of artificial tiger bone meal in regulating the expression level of interleukin-23/interleukin-17 immune axis in improving spine osteoarthritis in rats.METHODS:Sixty SD rats were randomly divided into blank control group,model group,artificial tiger bone meal low-,medium-and high-dose groups,with 12 rats in each group.Except for the blank control group,osteoarthritis models were established in the other groups by injecting 0.1 mL of iodoacetic acid into the joint cavity of the lumbar vertebral joint capsule of the rats.15 days after modeling,the artificial tiger bone meal low,medium and high dose groups were treated by intragastric administration of 120,240 and 480 mg/kg per day respectively.The blank control group and model group were given the same volume of normal saline by gavage.After 21 days of treatment,the expression levels of interleukin-17,interleukin-23,matrix metalloproteinase-3,and chemokine receptor-6 in rat spinal articular cartilage were measured by western blot assay.The expression levels of related inflammatory factors in rat serum were detected by ELISA.The degree of joint injury and degeneration in rats was observed by hematoxylin-eosin staining and safranin O-fast green staining.RESULTS AND CONCLUSION:(1)The results of western blot assay showed that the expression levels of interleukin 17,interleukin 23,matrix metalloproteinase 3,and chemokine receptor 6 in the articular cartilage of rats in the artificial tiger bone meal high-dose group were significantly lower than those in the model group(P＜0.05).(2)ELISA results showed that compared with the model group,the artificial tiger bone meal medium-and high-dose groups had a significant down-regulating effect on the levels of serum interleukin 17,tumor necrosis factor α,interleukin 1β,and matrix metalloproteinase 3(P＜0.05).(3)Hematoxylin-eosin staining and saffron O-solid green staining showed that the infiltration and proliferation of synovial inflammatory cells in each treatment group of artificial tiger bone meal were significantly improved compared with the model group,and the pathological inflammation Osteoarthritis Research Society International score and Mankin's score in the medium-and high-dose groups of artificial tiger bone meal were significantly reduced(P＜0.05).(4)It is suggested that artificial tiger bone meal could significantly improve the inflammation and degeneration of spinal facet joints caused by iodoacetic acid chemical stimulation.Among them,the effect of the high-dose group was more significant.The mechanism may be to inhibit the expression of interleukin-23/interleukin-17 immune axis-related inflammatory factors and improve the immune microenvironment of articular cartilage.

OBJECTIVE: To elucidate the effect of Huanglian-Renshen-Decoction (HRD) on ameliorating type 2 diabetes mellitus by maintaining islet β -cell identity through regulating paracrine and endocrine glucagon-like peptide-1 (GLP-1)/GLP-1 receptor (GLP-1R) in both islet and intestine. METHODS: The db/db mice were divided into the model (distilled water), low-dose HRD (LHRD, 3 g/kg), high-dose HRD (HHRD, 6 g/kg), and liraglutide (400 µ g/kg) groups using a random number table, 8 mice in each group. The db/m mice were used as the control group (n=8, distilled water). The entire treatment of mice lasted for 6 weeks. Blood insulin, glucose, and GLP-1 levels were quantified using enzyme-linked immunosorbent assay kits. The proliferation and apoptosis factors of islet cells were determined by immunohistochemistry (IHC) and immunofluorescence (IF) staining. Then, GLP-1, GLP-1R, prohormone convertase 1/3 (PC1/3), PC2, v-maf musculoaponeurotic fibrosarcoma oncogene homologue A (MafA), and pancreatic and duodenal homeobox 1 (PDX1) were detected by Western blot, IHC, IF, and real-time quantitative polymerase chain reaction, respectively. RESULTS: HRD reduced the weight and blood glucose of the db/db mice, and improved insulin sensitivity at the same time (P<0.05 or P<0.01). HRD also promoted mice to secrete more insulin and less glucagon (P<0.05 or P<0.01). Moreover, it also increased the number of islet β cell and decreased islet α cell mass (P<0.01). After HRD treatment, the levels of GLP-1, GLP-1R, PC1/3, PC2, MafA, and PDX1 in the pancreas and intestine significantly increased (P<0.05 or P<0.01). CONCLUSION HRD can maintain the normal function and identity of islet β cell, and the underlying mechanism is related to promoting the paracrine and endocrine activation of GLP-1 in pancreas and intestine.

This article comprehensively reviews the research progress in the management principles of acute closed soft tissue injuries,summarizing the retention and updates of the four main principles (RICE,PRICE,POLICE,and PEACE&LOVE) at different stages.Traditional methods such as compression,elevation,rest,and protection remain valuable.However,with the advancement in rehabilitation philosophy,early active rehabilitation plays an increasingly important role in the tissue healing process.Traditional cold therapy remains a choice because of its benefits.Non-steroidal anti-inflammatory drugs play a positive role in relieving the acute pain and swelling and improving the function of soft tissue,being preferred by both patients and medical practitioners.Therefore,advantages outweigh disadvantages in the clinical application of non-steroidal anti-inflammatory drugs.Finally,modern medical models have begun to incorporate more social and psychological factors,focusing on patients' mental state and social environment,while guiding patients to actively participate in the rehabilitation process,which can accelerate the recovery process and improve treatment outcomes.

OBJECTIVE: To investigate the efficacy of posterior three-columns osteotomy in the treatment of severe tuberculous angular kyphosis. METHODS: Total of 33 patients with severe tuberculous angular kyphosis were treated with posterior three-columns osteotomy from January 2006 to January 2019 including 24 males and 9 females with an average age of (40.6±23.3) years old ranging from 15 to 62 years old and an average disease duration of (23.5±15.5) years ranging from 4 to 40 years. The Cobb's angle of kyphosis was (118.65±28.82)°. Interradicular bone-disc-bone osteotomy(BDBO), posterior-only vertebral column resection (PVCR) and posterior multilevel vertebral osteotomy (PMVO) were performed to correct spinal deformity individually. The visual analogue scale (VAS), Oswestry disability index (ODI), sagittal vertical axis (SVA), ASIA spinal cord functional classification and motor function score, and deformity correction rate were measured and statistically analyzed before, after and at the final follow-up. RESULTS: Total of 33 patients were followed up from 15 to 96 months with an average of (38.00±6.38) months. The last follow-up of kyphosis Cobb angle (23.88±5.45)° showed no significant loss from postoperative 12 months (20.40±9.13)°, P>0.05. The SVA, VAS, ODI and ASIA spinal cord functional classification and motor function score were significantly improved at 1 year and last follow-up after operation(P<0.01). The fusion time of the osteotomy site was (18.50±5.16) months. The ASIA classification of 15 patients with spinal cord injury were improved by at least 2 grades after operation, and their daily life and work ability were various levels of restored. Postoperative complications of spinal cord injury occurred in 3 cases. CONCLUSION Posterior three-columns osteotomy is the most effective method for the treatment of angular kyphosis of spinal tuberculosis.Careful preoperative design and individualized osteotomy can not only correct the deformity, but also a successful decompression to the spinal cord and promote the recovery of spinal cord function.
