Osteoarthritis (OA) is a common chronic degenerative disease of the skeletal system and muscular system, and its pathogenesis remains unclear, leading to a lack of effective therapeutic strategies. Ribonucleic acid binding proteins (RBP), as key regulators of post-transcriptional processes, can specifically bind to targeted ribonucleic acids (RNA) and modulate their function and fate. By regulating various aspects of RNA metabolism, including transcription, splicing, modification, stabilization, and translation, RBPs influence the onset and progression of OA. Exploring the regulatory mechanisms of RBPs under physiological and pathological conditions, elucidating the role of RBPs in the occurrence and development of OA, and discussing current challenges and future directions in RBPs research, hold significant importance for the treatment of OA by targeting RBPs.

Objective To investigate the clinical outcomes of hemiarthroplasty with Wagner SL prosthesis in treating failed internal fixation of intertrochanteric fractures of elderly patients.Methods Aretrospective case series study was conducted on the clinical data of 14 patients with failed internal fixation of intertrochanteric fractures admitted between March 2015 to April 2018.There were seven males and seven females with a mean age of 82.2 years (range,75-94 years).The primary internal fixators were proximal femoral nail anti rotation in nine patients,dynamic hip screw in three patients,and proximal femoral locking plate in two patients.The main causes of internal fixation failure were screw loosening in six patients,cutting out of screws in five patients,nonunion in two patients,and plate breakage with nonunion in one patient.Affected limb shortening and coxa varus deformity to various degrees were seen in all the patients before operation.The mean interval from internal fixation to hemiarthroplasty was 6.6 months (range,2-12 months).All patients received hemiarthroplasty using Wagner SL prosthesis,of which nine patients had additional trochanter claw plate with titanium cable fixation and two patients had tension band wire fixation.The operation time,intraoperative,and postoperative complications were recorded.Harris hip scores were measured before operation and at the last follow up to evaluate hip function.Radiographs were performed to assess the fracture healing,prosthesis position,and biological fixation.Results All patients were followed up for 6-30 months (mean,14.5 months).The mean operation time was (108.0 ± 12.4) minutes (range,88-130 minutes).No iatrogenic fracture occurred during the operation.One patient was seen contralateral intertrochanteric fracture during follow-up,and no complications such as periprosthetic fracture,prosthetic sinking,and infection occurred in the 13 patients.The Harris score increased from (26.1-±7.5)points before operation to (83.1 ±4.1)points after operation (P ＜ 0.01).All patients were able to stand and walk,of which four needed crutch assistance.At the last follow-up,X-ray film showed that the prosthesis was well positioned and that all of them reached bony fixation.Fourteen cases of greater trochanteric fracture were healed,with two cases of slight displacement.Conclusions Hemiarthroplasty is an effective remedial treatment for failed internal fixation of intertrochanteric fractures in the elderly,which can improve hip function and enhance the life quality of patients.Wagner SL prosthesis can obtain stable fixation.

Objective To evaluate the efficacy of phonophoresis of etofenamate gel for postoperative analgesia after total knee arthroplasty (TKA).Methods A total of 80 adult patients were randomly divided into experimental and control groups (n =40 in each group).The same basic analgesia protocol was performed in both groups,while phonophoresis of etofenamate gel was performed only in the experimental group (twice per day,from day 1 to day 7,postoperatively).Data recorded during an 8-week follow-up included Visual Analogue Scale (VAS) scores at rest and during continuous passive motion before surgery and 1 d,3 d,5 d,and 7 d after surgery,range of motion before surgery and 3 d,5 d,7 d,and 8 weeks after surgery,and Hospital for Special Surgery (HSS) scores before surgery and 8 weeks after surgery.SPSS 18.0 was used for statistical analysis.Results The VAS scores at rest and during continuous passive motion 3 d,5 d,and 7 d after surgery were lower in the experimental group than in the control group (P ＜ 0.05).The range of motion 3 d,5 d,7 d,and 8 weeks after surgery was better in the experimental group than in the control group (P ＜ 0.05).The HSS scores 8 weeks after surgery were better in the experimental group than in the control group (P ＜ 0.05).Conclusion Phonophoresis of etofenamate gel provides effective pain control after TKA and is helpful for early functional recovery.

Objective To explore the imaging radiological and clinicopathological characteristics of benign fibrous histiocytoma (BFH) of bone, in order to improve the imaging diagnostic accuracy of the disease Methods Radiological and clinical data of 16 patients with BFH confirmedbypathology were retrospectively analyzed , and relevant literatures were reviewed. Results The X-ray findings of 14 BFHpatients were osteolytic lesion , expansive destruction of bone,without soft tissue involvement, 10 with residual apophysis,9 with osteosclerosis marginal; CT was performed on 2 patients. Expansive destruction of bone and soft tissue densities were seen inside the loops , 1 case remarkable enhancement of the lesion. MRI was performed on 9 patients and 5 cases showed long T1 and T2 signal intensity; 1case showed equal T1 and long T2 signal intensity in cystic part and equal T1 and T2 signal intensity in the solid part. One patient had pathological fracture, and the surrounding soft tissue invaded, showing equal T1 and long T2 signal intensity. Two lesions located at spinous process of cervical vertebra , showing long T1 short T2 and equal T1 and T2 signal intensity. Linear low signal separation shadow in T1 and T2 could be seen in 6 cases. Long T1 and short T2 sclerotic ring were seen in 4 cases. Solid part of tumor and linear separator were obviously enhanced. Conclusions The radiological findings of benign fibrous histioeytoma of bone indicate some characteristics. The combination with X-ray , CT and MRI examination is helpful to improve the diagnostic accuracy of the disease before operation.

Objective:To explore the correlation between ascending aortic elasticity and coronary blood flow reserve (CFR)in patients with hypertension.Methods:A total of 60 patients with essential hypertension were regarded as hypertension group,another 50 normotensive subjects were enrolled as normal control group during the same period. Ascending aortic dilation (D),stiffness (β)and CFR were measured and calculated by tissue Doppler ultrasound,then compared between two groups.Pearson correlation analysis was used to analyze the correlation amongβ,D and CFR.Results:Compared with normal control group,there were significant reductions in D [(3.59±0.30)10-6 cm2/d vs.(2.88±0.77)10-6 cm2/d]and CFR [(3.23±1.16)vs.(2.02±0.63)],and significant rise inβ[(3.54 ±1.52)vs.(5.46±1.98)]in hypertension group,P<0.05 or<0.01. Pearson correlation analysis indicated thatβwas significant inversely correlated with CFR (r=-0.413,P=0.005),while D was significant positively correla- ted with CFR (r=0.384,P=0.003 ).Conclusion:Reduced ascending aortic elasticity is significantly correlated with coronary blood flow reserve.

Objective To analyze, the risk factors and related psychological factors in patients with gastroesophageal reflux disease (GERD)and survey the curative effect. Methods All of 200 outpatients with GERD(GERD group) and 200 healthy persons (control group)from January 2006 to January 2008 were randomly selected, and the personal data were investigated. The GERD questionnaire (RDQ) and the Zung-self-rating depression scale (SDS) test were used. Results In GERD group, the proportions of high education, city living, marriage instability ,heavy working pressure, high body mass index (BMI),smoking and drinking habit, peptic disease in family, using nonsteroidal anti-inflammatory drugs (NSAIDs) were higher than those in control group (Pall < 0.01). After treatment, the patients in GERD group had lower scores in the RDQ and SDS test than those before treatment (P< 0.01). Conclusions There are many risk factors in patients with GERD, especially the psychological factors. The therapy of GERD should combine with psy-chotherapy and avoid high BMI, smoking, drinking and overusing the NSAID.
