Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

BACKGROUND:Our previous research found that Panax notoginseng can repair the morphological structure of bone cells,which has a good application prospect in the treatment of osteoarthritis,but the specific mechanism of Panax notoginseng is still unclear. OBJECTIVE:To identify the main components of Panax notoginseng using ultra-high performance liquid chromatography-Q exactive-mass spectrometry(UHPLC-QE-MS),and to explore the mechanism of Panax notoginseng in the treatment of osteoarthritis by combining network pharmacology,molecular docking and molecular dynamics simulation. METHODS:After identifying the main components of Panax notoginseng by UHPLC-QE-MS technology,the active components were screened by TCMSP database,and the targets of active components were found by TCMSP and Uniprot database.Osteoarthritis targets were screened out through disease databases.After the intersection of drug targets and disease targets,the protein-protein interaction network was constructed by importing STRING database and Cytoscape software,and the"active ingredient-action target"network was constructed to screen key active ingredients.Then the key targets were enriched and analyzed,and the key active components and key targets were verified by molecular docking.Finally,the results with the lowest binding energy were selected for molecular dynamics simulation. RESULTS AND CONCLUSION:A total of 57 active components were identified in the solution of Panax Notoginseng,including 50 intersection targets of components and disease targets,5 key active components(quercetin,ursodeoxycholic acid,kaempferol,naringenin and erythrocyanine),and 5 key targets(interleukin 6,matrix metalloproteinase 9,interleukin 1β,albumin and recombinant chemokine c-motif ligand 2).Gene ontology enriched 642 entries,among which 620 entries represent biological processes,21 entries represent molecular functions,and 1 entry represents cellular components.Kyoto encyclopedia of genes and genomes analysis indicated 63 pathways,mainly including estrogen signaling pathway,interleukin 17 signaling pathway and hyperglycosylation end product-hyperglycosylation end product receptor signaling pathway.Molecular docking showed good binding activity of key active components and key targets.Molecular dynamics simulation indicated that the stable interaction between quercetin and matrix metalloproteinase 9.The composition of Panax notoginseng was comprehensively studied,and the material basis of its efficacy was preliminarily clarified.It was predicted that Panax notoginseng could play an anti-inflammatory,cartilage-protective,and immunomodulatory role in treating osteoarthritis through multiple components,targets,approaches and pathways.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Brassica juncea is a yearly or biennial vegetable in Brassica of Cruciferae. The yield and quality of its product organs are affected by flowering time. WRKY proteins family can respond to biological and abiotic stresses, developmental regulation and signal transduction. WRKY75 is an important member of WRKY family which can regulate flowering, but the flowering regulation mechanism in B. juncea has not been reported. In this study, a gene BjuWRKY75 in B. juncea was cloned, and the encoded-protein belonged to the group Ⅱ of WRKY protein with highly conserved domain. BjuWRKY75 had the highest homology with BriWRKY75 of Brassica nigra. The relative expression level of BjuWRKY75 in flowers was significantly higher than that in leaves and stems, and it was expressed stably in leaves. BjuWRKY75 protein was localized in the nucleus and interacted with the promoter of the flowering integrator BjuFT, which contained the W-box response element for the interaction between protein and DNA. Thus, it could transcriptionally activate the expression of the downstream genes. The overexpression of BjuWRKY75 in Arabidopsis led to earlier flowering significantly. In conclusion, BjuWRKY75 could directly target the promoter of BjuFT and accelerate flowering. These results may facilitate further study on the regulation of flowering molecules of BjuWRKY75.

Objective:To investigate the clinical effects and indications of tibial condylar valgus osteotomy (TCVO) in treating varus unicompartmental knee osteoarthritis.Methods:A retrospective analysis was conducted in 32 patients (45 knees) who suffered from varus unicompartmental knee osteoarthritis and underwent TCVO from June 2016 to June 2018. These patients were aged 65.8±8.3 (range from 52 to 79) years, including 12 males (18 knees) and 20 females (27 knees). All enrolled individuals presented obvious expansion of the lateral joint space with joint line convergence angle (JLCA) of 7.19°±2.69°. Based on the full-length standing X-ray imaging of the lower limbs at before and 2 years after surgery, the percentage of mechanical axis (%MA), femorotibial angle (FTA), hip-knee-ankle angle (HKA), lateral distal femoral angle (LDFA) and medial proximal tibial angle (MPTA) were measured and analyzed to evaluate the improvements of lower extremity alignments. The medial tibial plateau depression (MTPD), posterior proximal tibial angle (PPTA), JLCA and joint space width (JSW) were measured and analyzed to evaluate the congruency of the knee joint and shape of the tibial plateau based on positive and lateral radiographs of knee joint. In addition, visual analogue scale (VAS) and Western Ontario and McMaster Universities (WOMAC) score were evaluated to assess the clinical effects of TCVO pre-operatively and at 1 year or 2 years after surgery.Results:All patients were followed up for 33.4±7.4 (range from 25 to 40) months. Comparing to the preoperative radiological data, %MA at 2 years after surgery increased from 3.78%± 14.34% to 66.16%±9.90%, FTA from 185.41°±4.45° to 170.81°±2.87°, HKA from 169.69°±1.70° to 181.16°±2.39°, MPTA from 83.03°±3.20° to 90.84°±3.67° all with statistical significance ( P<0.05). There was no significant difference for PPTA between before (89.22°±1.52°) and 2 years (88.97°±1.57°) after surgery ( t=0.638, P=0.526). MTPD improved from -7.81°±3.27° to 5.78°±2.19° ( t=19.218, P<0.001). However, there was no significant difference for PPTA between before (81.63°±3.28°) and 2 years (82.25°± 2.21°) after surgery ( t=0.881, P=0.382). JLCA reduced from 7.19°±2.69° to 0.22°±2.09°. The medial and lateral JSW were corrected from 2.45±0.23 mm and 5.86±0.25 mm to 3.73±0.27 mm and 4.68±0.34 mm ( P<0.05), respectively. Additionally, VAS and WOMAC scores improved from 6.46±2.21 and 52.66±16.69 preoperatively to 2.94±1.72 and 19.31±14.87 at 1 year after surgery, and to 1.39±1.45 and 13.66±15.44 at 2 years after surgery, respectively ( P<0.05). Conclusion:Satisfactory early therapeutic outcomes could be achieved by TCVO in varus unicompartmental knee osteoarthritis with subluxated lateral joint and increased JLCA. TCVO can correct intra-articular varus deformity, adjust mechanical axis and relieve knee joint pain and dysfunction.

Type H endothelial cells (CD31 hiEMCN hi), a special subtype of vascular endothelial cells, are distributed mainly in endosteum and long bone metaphysis. They recruit and activate osteoprogenitor cells and promote endochondral ossification through paracrine, thereby promoting osteogenesis. On the contrary, their biological activities can be regulated by osteoclasts and osteoblasts. At the same time, the mutual regulation of type H endothelial cells is also closely related to the process of angiogenesis and osteogenesis. This article reviews the characteristics and cytokine expression profiles and the mediating role in mutual regulation of angiogenesis and osteogenesis of the cells, offering an insight for establishment of a bone regeneration strategy based on the coupling of angiogenesis and osteogenesis.
