BACKGROUND:Although researchers have noted that fibroblast growth factor receptor 1 shows great potential in rheumatoid arthritis bone destruction,there is a lack of reviews related to the potential mechanisms of fibroblast growth factor receptor 1 in rheumatoid arthritis bone destruction. OBJECTIVE:To comprehensively analyze the mechanism of fibroblast growth factor receptor 1 in bone destruction in rheumatoid arthritis by reviewing the relevant literature at both home and abroad. METHODS:We searched the CNKI database using the Chinese search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,bone cells,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,vascular endothelial cells."PubMed database was searched using the English search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,osteocytes,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,endothelial cells."The search period focused on April 1992 to January 2024.After screening the literature by reading titles,abstracts,and full texts,a total of 82 articles were finally included for review according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Fibroblast growth factor receptor 1 was found to be widely expressed in bone tissue-associated cells,including osteoblasts,osteoclasts,and osteoclasts.Fibroblast growth factor receptor 1 affects bone remodeling and homeostasis by regulating the function of these cells,as well as promoting the onset and progression of bone destruction in rheumatoid arthritis.Fibroblast growth factor receptor 1 is involved in the inflammatory response of synovial fibroblasts and macrophages and regulates angiogenesis of endothelial cells in synovial tissues.Fibroblast growth factor receptor 1 promotes bone destruction in several ways.Fibroblast growth factor receptor 1 may be a potential causative agent of bone destruction in rheumatoid arthritis and provides a reference for further research on its therapeutic targets.

Objectives: This study aimed to achieve expert consensus on menopause management in the Asia-Pacific region, taking into account patient diversity, the latest evidence, and current treatment options. Methods: A focused literature search was performed to identify clinical practice statements on menopause management. Menopause experts were nominated by members of the Asia-Pacific Menopause Federation (APMF) society. A modified Delphi methodology, involving iterative rounds of anonymous surveys, was employed until consensus was reached for each statement. Consensus was defined as ≥ 70% of experts voting ‘agree’ or ‘strongly agree’ for a given clinical practice statement. Results: A total of 39 participants from 14 different APMF member societies were involved. Eighty-five clinical practice statements reached a consensus. Based on the clinical practice statements, an algorithm was created as a tool to guide clinicians on menopause management. APMF experts agreed that, in addition to vasomotor symptoms, Asian women experiencing somatic or psychological symptoms may also benefit from treatment with menopausal hormone therapy (MHT). MHT should also be considered for the prevention of osteoporosis in asymptomatic peri- and postmenopausal women. Conclusions This APMF consensus statement supersedes the previous one published in 2008. It provides guidance to gynecologists, endocrinologists, family physicians, and other healthcare professionals in delivering optimal care to menopausal women in the ethnically and culturally diverse Asia-Pacific region.

BACKGROUND:The biomechanical stability of basal femoral neck fracture is poor,and the treatment plan is different from the traditional femoral neck fracture. At present,there is still no consensus on the surgical plan for the treatment of basal femoral neck fracture in young adults. OBJECTIVE:To compare the biomechanical characteristics of proximal femoral nail antirotation and femoral neck system in the treatment of basal femoral neck fractures by finite element analysis.METHODS:First,Mimics Medical 21.0 software was used to extract the right femur CT data of healthy young female volunteers to establish a preliminary model. Secondly,the model was imported into Geomagic Wrap 2021 software for further smoothing. SOLIDWORKS 2021 software was used to establish and assemble the femoral neck base fracture model,proximal femoral nail antirotation model,and femoral neck system model. Finally,the assembled model was imported into Workbench 2021 R1 software for biomechanical analysis.RESULTS AND CONCLUSION:(1) Stress distribution:the stress distribution of the proximal femoral nail antirotation group was mainly near the fracture line and the medial side of the femur,and the peak stress was 151.90 Mpa. In the femoral neck system group,the stress distribution of the femoral model was mainly near the fracture line,and the peak stress was 290.74 Mpa. The proximal femoral nail antirotation internal fixation stress was mainly distributed at the proximal end of the helical blade and the main nail,and the peak stress was 102.95 Mpa. The stress distribution of internal fixation in femoral neck system mainly extended to both sides of the support rod,and the peak stress was 184.69 Mpa. (2) Total displacement:the maximum displacement of the femoral model in the proximal femoral nail antirotation group was 4.0323 mm,and the maximum displacement of the femoral model in the femoral neck system group was 4.6489 mm. The maximum displacement was located in the femoral head. The peak displacement of internal fixation in the proximal femoral nail antirotation group and the femoral neck system group was 2.7094 mm and 3.1303 mm,respectively. The displacement of internal fixation in the two groups was mainly concentrated in the proximal end of internal fixation,and gradually decreased to the distal end. (3) It is concluded that in the femoral neck base fracture model,whether it is the femoral model or the internal fixation model,the proximal femoral nail antirotation group has more dispersed stress distribution,lower stress peak,smaller femoral head displacement,and better biomechanical stability than the femoral neck system group.

BACKGROUND:The treatment of Pauwels type Ⅲ femoral neck fractures in young adults is extremely difficult.When treating Pauwels type Ⅲ femoral neck fractures with internal fixation,it is not only necessary to ensure the mechanical stability of the internal fixation,but also to ensure that it can resist the impact of shear,compression and tension,so as to prevent the internal fixation from breaking or loosening due to fatigue during the fracture healing process.However,existing internal fixation methods do not fully meet our requirements for the treatment of this fracture.OBJECTIVE:To provide a more reasonable and effective choice of internal fixation mode for clinicians in the treatment of young adults with Pauwels type Ⅲfemoral neck fracture,so as to optimize the treatment effect,reduce the occurrence of complications,and improve the recovery speed and quality of life of patients.METHODS:A femoral neck fracture model with Pauwels angle of 70° was constructed using CT data extracted from volunteers,and three placement modes were set up:(1)femoral neck system group:the main nail of femoral neck system was located in the center of the femoral neck axis.(2)Combination group:The main nail of femoral neck system was located in the lower third of the femoral neck axis,and a cannulated compression screw was located in the upper third of the femoral neck axis.(3)Cannulated compression screw group:The arrangement of three cannulated compression screws was arranged in the classic inverted triangle shape to ensure the maximum fixed effect.Stress distribution and displacement of proximal femoral fracture fragments and internal fixation devices were analyzed under three different internal fixation methods.RESULTS AND CONCLUSION:(1)The stress of the proximal femur models in the three groups was concentrated near the fracture line:combination group(201.10 MPa)＜femoral neck system group(222.25 MPa)＜cannulated compression screw group(271.25 MPa).(2)The peak value of proximal femur displacement was located at the top:combination group(6.33 mm)＜femoral neck system group(9.37 mm)＜cannulated compression screw group(9.92 mm).(3)The internal fixation stress was concentrated on the screw surface at the broken end of the fracture and gradually extended from there to both sides;cannulated compression screw group(136.67 MPa)＜combination group(201.10 MPa)＜femoral neck system group(222.25 MPa).(4)The maximum displacement of the internal fixation device model was located at the very top of the internal fixation.The three groups gradually decreased from the top to the far end.The peak displacement values of combination group(6.21 mm)＜femoral neck system group(9.19 mm)＜cannulated compression screw group(9.51 mm).(5)The stress of proximal bone mass in the three models was mainly concentrated in the fracture end,especially in the lower part of the fracture end.This indicates that these regions were subjected to greater stress and strain during mechanical transfer;combination group(24.96 MPa)＜femoral neck system group(39.69 MPa)＜cannulated compression screw group(44.47 MPa).(6)The results indicate that the internal fixation strategy of femoral neck system combined with cannulated compression screw arranged in parallel coronal surface shows higher biomechanical stability than single femoral neck system fixation or cannulated compression screw in inverted triangle arrangement fixation,and provides a more reliable and effective solution for the treatment of Pauwels type Ⅲ femoral neck fracture in young adults.

Objective To compare the clinical efficacy of the transforaminal endoscopic lumbar discectomy(TELD)approach with that of the interlaminar endoscopic lumbar discectomy(IELD)approach,both performed using a single-channel spinal endoscope,in the treatment of L4-L5 degenerative lumbar lateral recess stenosis(DLLRS).Methods A retrospective analysis was conducted on 78 patients with L4-L5 DLLRS who underwent single-channel endoscopic spinal surgery at our institution between March 2020 and March 2024.Patients were classified into the TELD group(lateral transforaminal approach,n=34)and the IELD group(interlaminar approach,n=44).Propensity score matching(PSM)was performed in a 1∶1 ratio using age,sex,body mass index(BMI),and duration of symptoms as covariates,yielding 25 matched pairs for final comparative analysis.Perioperative outcomes were systematically compared between groups.Visual analog scale(VAS)scores for low back pain and leg pain,as well as the Oswestry Disability Index(ODI),were evaluated preoperatively and at 3 days,3 months,6 months,and 1 year postoperatively.Lumbar computed tomography(CT)scans obtained 3 days after surgery were used to measure the lateral recess angle(LRA)and assess the extent of decompression.Spinal stability was evaluated using dynamic lumbar radiographs at 3 months postoperatively.Clinical outcomes were assessed 1 year after surgery based on the modified MacNab criteria.Results Both groups showed significant reductions in VAS scores for low back and leg pain,as well as in ODI scores,at all postoperative time points compared to baseline values(P<0.05).However,no statistically significant differences were observed between the two groups(P>0.05).Lumbar CT scans performed on postoperative day 3 demonstrated a significant increase in LRA in both groups relative to preoperative measurements(P<0.05).Although the magnitude of increase was greater in the IELD group,the intergroup difference did not reach statistical significance(P>0.05).At 3 months postoperatively,dynamic lumbar radiographs revealed no deterioration in spinal stability in either group compared to preoperative conditions,with no significant difference between groups(P>0.05).According to the modified MacNab criteria at 1 year postoperatively,the excellent and good outcome rate was 88.0%in the TELD group and 92.0%in the IELD group,with no statistically significant difference between the groups(P>0.05).Conclusions Both the TELD and IELD techniques are safe and effective for managing L4-L5 DLLRS,yielding comparable clini-cal outcomes.The selection of surgical approach should be guided by the anatomical location of ventral disc protru-sions,as well as the degree of facet joint hypertrophy and neural compression.
