BACKGROUND:As a common disease in middle-aged and elderly,osteoarthritis is difficult to cure,and the pathogenesis is not clear.Long non-coding RNA participates in the pathogenesis of osteoarthritis through many ways,such as regulating translation,promoting or inhibiting mRNA,and adsorbing miRNAs. OBJECTIVE:To review the types of common long non-coding RNA in osteoarthritis,and the influence of multiple long non-coding RNAs on the pathological factors related to osteoarthritis,to analyze the future application of long non-coding RNAs in osteoarthritis. METHODS:Literature retrieval was conducted in CNKI,WanFang Data,VIP database,PubMed,Web of Science and Sciencedirect databases,using the search terms of"osteoarthritis,degenerative joint disease,degenerative arthritis,OA,LncRNA,long non-coding RNA,long noncoding RNA,long intergenic non-coding RNA"in Chinese and English.All relevant literature published from 1976 and May 2024 was retrieved.After literature screening,induction,analysis and summary,93 articles were finally included for review. RESULTS AND CONCLUSION:This review collected 25 long non-coding RNAs that are well studied with osteoarthritis.Long non-coding RNAs,as a molecular sponge for miRNA,are competing endogenous RNAs to competitively adsorb miRNAs and then affect downstream targets.Long non-coding RNAs can regulate physiopathological processes such as chondrocyte apoptosis and proliferation,cartilage extracellular matrix degradation,and inflammatory responses.Long non-coding RNAs are expected to become a biomarker and potential therapeutic target for the clinical diagnosis and therapeutic prognosis of osteoarthritis,and it may become a new strategy for the clinical treatment of osteoarthritis in the future.

One patient with kidney stones was prescribed Paishi granules and diclofenac sodium sustained-release tablets for pain relief in the outpatient setting.That evening,the patient took 1 sachet of Paishi granules and 1 diclofenac sodium sustained-release tablet together.The patient subsequently developed a generalized rash with itching.Liver function indexes of alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(T-BiL),direct bilirubin(D-BiL),and alkaline phosphatase(ALP)were all 2 to 6 times higher than the upper limit of normal.After symptomatico treatment,the patients systemic rash had subsided,and the liver function indicators have returned to normal.

In order to effectively prevent and control the occurrence of catheter-associated urinary tract infection and ensure the safety of both patients and medical personnel,the National Health Commission of the People's Re-public of China officially released the recommended health industry standard"Standard for prevention and control of catheter-associated urinary tract infection"(WS/T862-2025)in Aug.2025.This paper provides an interpreta-tion of the standard,covering its drafting background,basis and content,to assist relevant medical personnel in healthcare institutions in enhancing their understanding and recognition of the standard,and to further promote its implementation and enforcement.

Preoperative localization of pulmonary small nodules can effectively improve the safety and success rate of video-assisted thoracoscopic surgery(VATS),but there are still controversies regarding the selection of relevant techniques.Interventional Oncology Committee of the Chinese Anti-Cancer Association organized domestic interventional radiology experts engaged in treatment of pulmonary malignancies,based on clinical experience and evidence-based medical evidence to formulate this Chinese expert consensus on preoperative auxiliary localization techniques for VATS of pulmonary small nodules.

Objective To explore the value of 3D and 2D radiomics features models based on multiparameter MRI in predicting Ki-67 expression(with 14%and 20%as the critical values,respectively)in breast cancer.Methods The MRI images of 147 patients with pathologically confirmed Luminal breast cancer were analyzed retrospectively.The patients were randomly divided into training set and test set according to the ratio of 7︰3.The 3D and 2D radiomics features of intratumor and peritumor were extracted from diffusion weighted imaging(DWI),dynamic contrast enhancement(DCE)mask(S0)and DCE phase 3(S3)images.Then the models were constructed by multiple pipeline combinations of three feature normalization methods,two feature dimensionality reduction methods,four feature selection methods,and ten classifiers.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)were used to evaluate the prediction performance of the models in order to select the best 3D and 2D single parame-ter(DWI,S0,S3)and multiparameter combination(S0+S3,S0+DWI,S3+DWI,S0+S3+DWI)models.Finally,the differ-ences between the models were compared by De Long test.Results With 14%as the critical value,the AUC of 3D and 2D models in the training set were 0.726-0.824 and 0.707-0.835,respectively,and those in the test set were 0.724-0.82 and 0.701-0.805.With 20%as the critical value,the AUC of 3D and 2D models in the training set were 0.743-0.868 and 0.793-0.881,respectively,and those in the test set were 0.738-0.853 and 0.743-0.814.There was no significant statistical difference between 3D and 2D models with the same parameter in the two critical values standards.Conclusion The multiparameter MRI-based radiomics models can bet-ter predict the expression of Ki-67 in breast cancer,and the models based on intratumor and peritumor 3D and 2D features have the same prediction efficiency.

Objective:To evaluate the functional outcomes and postoperative complications associated with modified Toupet-like (mToupet-like) anastomosis following proximal gastrectomy for patients with gastric tumors.Methods:After proximal gastrectomy, barbed sutures (2-3 stitches) in the seromuscular layer were used to secure the anterior wall of the stomach at a distance of 1-2 cm from the closure line and the posterior wall of the esophagus at a distance of 5.0 cm from the closure line. The remnant stomach was then positioned posterior to the esophagus on the greater curvature side. Esophagogastric anterior wall anastomosis (manual or circular stapling) was performed at the greater curvature of the remnant stomach, 3 cm distal to the gastroesophageal fixation point. A Toupet-like folding procedure was conducted by folding the reconstructed gastric fundus and wall anteriorly from behind the esophagus and embedding the esophagus within a 270° wrap at the site of stomach-esophagus fixation.Results:Twelve patients with gastric tumors underwent proximal partial gastrectomy with mToupet-like anastomosis in the Department of Gastric Surgery at Zhejiang Cancer Hospital from January to March 2024. Among them, 10 diagnosed as upper gastric adenocarcinoma, and 2 diagnosed as gastric gastrointestinal stromal tumors. The cohort included nine male patients and three female patients, aged 46 to 77 years old, with a body mass index (BMI) ranging from 19.7 to 27.3 kg/m2. The maximum tumor diameter was less than 4 cm, and the predicted residual gastric volume exceeded one-half. Laparoscopic surgery was performed in 11 patients, while only 1 patient underwent open surgery. The mean duration of mToupet-like anastomosis was 48.3±8.7 minutes with an estimated intraoperative blood loss was 53.0±11.2 ml. All the 12 patients successfully achieved R0 resection. Among these patietns, the median postoperative hospital stay was 8.5 (7.0, 11.0) days, and the average hospitalization cost was 5.0±0.2 ten thousand yuan. No Clavien-Dindo grade II or higher complications were observed during the perioperative period. Patients were followed up for 6 to 8 months after operation, and no cases of reflux esophagitis were detected by gastroscopy, and no patient required long-term oral proton pump inhibitors.Conclusions:mToupet-like anastomosis for digestive tract reconstruction after proximal gastrectomy is a safe and feasible technique, demonstrating favorable preliminary efficacy.

Objective To observe the value of endovascular stenting(EVS)for treating transverse sinus stenosis(TSS)-related unilateral pulsatile tinnitus(PT).Methods Totally 42 patients with TSS-related unilateral PT who underwent EVS were retrospectively enrolled.The technical and clinical success rates of EVS for treating TSS-related unilateral PT were evaluated,and the complications and recurrence after treatment were observed.Results Among 42 cases,stent implantation was successfully performed in 40 cases,with the technical success rate of EVS was 95.24%(40/42).After treatment,the tinnitus symptoms in the above 40 cases improved significantly,the tinnitus handicap inventory(THI)score immediately decreased to mild PT,the trans-stenotic pressure gradient(TPG)decreased from 8.00(6.00,11.75)mmHg before treatment to 1.00(1.00,1.00)mmHg,and the clinical success rate of EVS was 100%(40/40).During the follow-up period,no serious complication was found.PT recurred 3 months after treatment in 1 case but spontaneously released 3 months later without any management.Conclusion EVS was safe and effective for treating TSS-related unilateral PT.

Objective:In alignment with the practical teaching objectives of Diseases of the Locomotor System and the competency requirements for graduates of military medical universities, this study conducted a multidimensional modification of the traditional objective structured clinical examination (OSCE) to provide a novel training mode that enhances the effectiveness of practical teaching of this course.Methods:The traditional OSCE was modified from the four dimensions of integration, individuality, immersion, and intelligence. The first three stations were set as "diagnosis" and the last three stations were set as "operation" to reflect the "integration" of diagnosis and treatment. The last station of "operation" was set as "medical cares of combat and training injuries" to reflect "individuality" of military medical training. The method of situation creation was used to reflect "immersion", and the application of intelligent terminals reflected "intelligence". The study involved 50 trainees who were assigned to either a modified OSCE group or a traditional teaching group through a random drawing process. The teaching effectiveness was assessed through evaluation of theoretical knowledge, practical skills, and participant satisfaction. The statistical analysis was conducted by SPSS 22.0, with parametric data assessed by t-tests and non-parametric data assessed by chi-square tests. Results:Before entering the department, there were no statistically significant differences in theoretical ( P=0.832) and practical ( P=0.513) scores between the two groups of trainees. However, after the internship, the modified OSCE group demonstrated significantly enhanced scores compared to the traditional teaching group, both in theory assessment [(93.88±1.92) vs. (90.76±2.85), P=0.001] and skill assessment [(94.32±1.25) vs. (91.68±2.82), P=0.001]. Additionally, the self-assessment of clinical capability improvement by the modified OSCE group was markedly higher across all dimensions than the traditional teaching group ( P=0.001). Furthermore, the evaluation conducted by basic combat unit on the job competency of graduated trainees indicated that the modified OSCE group outperformed the traditional teaching group in basic clinical diagnosis and treatment [(4.72±0.46) vs. (3.44±0.71), P=0.001], emergency management of combat and training injuries [(4.72±0.46) vs. (3.52±0.71), P=0.001], application of information technology [(4.44±0.71) vs. (3.91±0.80), P=0.029], basic military qualities [(4.40±0.71) vs. (3.92±0.91), P=0.043], mental health and resilience [(4.36±0.70) vs. (3.68±0.85), P=0.003], and the capacity for continuous learning [(4.64±0.70) vs. (3.83±0.76), P=0.001]. Conclusions:The modified OSCE teaching mode can better meet the practical teaching requirements for Diseases of the Locomotor System in the military medical university and thus holds promise for further application.
