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.

BACKGROUND:With a gradually aging population,improving the ability to screen for the risk of death after arthroplasty and implementing timely personalized intervention programs for the increasing number of elderly patients with femoral neck fractures is key to improving the postoperative status of patients and prolonging survival expectations. OBJECTIVE:To investigate the risk factors for postoperative mortality in elderly patients with femoral neck fractures and to construct a nomogram predictive model to predict their mortality risk. METHODS:The study was conducted on 155 elderly patients(≥65 years old)who underwent arthroplasty for femoral neck fracture from January 2016 to January 2021,and 147 patients who met the inclusion criteria were analyzed to collect clinical data that may affect the patients'postoperative mortality.Single-factor and multi-factor Cox regression analyses were successively used to screen independent risk factors associated with postoperative mortality.The column line graph model was constructed and validated using Rstudio software. RESULTS AND CONCLUSION:(1)Age,frailty(age-adjusted Charlson comorbidities score),preoperative activity status,osteoporosis,and postoperative serum albumin level were five independent risk factors for postoperative mortality in elderly patients with femoral neck fractures(P<0.05).(2)The nomogram predictive model was constructed based on the results of multifactorial analysis,with a consistency index of 0.819(95%CI:0.771-0.868).Receiver operating characteristic curve analysis showed that the area under curve for 1-year and 3-year survival prediction was 0.8543 and 0.7263,respectively,indicating that the nomogram predictive model has good discriminatory and predictive power;calibration curve and decision curve analysis also showed good model discriminative power and clinical utility value.(3)The constructed nomogram predictive model has good diagnostic efficacy and accuracy,and can effectively assess the risk of postoperative death of patients.

BACKGROUND:Arthroplasty is the primary treatment for displaced femoral neck fractures in the elderly,and the choice of total hip arthroplasty versus hemiarthroplasty is currently the subject of considerable debate. OBJECTIVE:To compare the mid-and long-term survival status of total hip arthroplasty versus hemiarthroplasty under a direct anterior approach for displaced femoral neck fractures in the elderly based on the propensity score matching method. METHODS:One hundred and forty-seven elderly patients(≥65 years of age)with displaced femoral neck fractures were admitted from January 2016 to January 2021,of whom 88 had total hip arthroplasty(total hip arthroplasty group)and 59 had artificial femoral head replacement(hemiarthroplasty group).For the patients'preoperative comorbidities,the age-corrected Charlson Comorbidity Scale was used to quantify the scores and calculate patient frailty.The propensity score matching method was used to match the two groups 1:1 and to compare the operation time,bleeding,postoperative hospitalization time,hospitalization cost,nutritional index,postoperative complications,and mortality between the two groups after matching.Postoperative survival time was determined by Kaplan-Meier Survival analysis. RESULTS AND CONCLUSION:(1)After propensity score matching,a total of 42 matched pairs were successful in both groups,and the preoperative data of patients in both groups were balanced and comparable after matching(P>0.05).(2)Compared with the hemiarthroplasty group,operation time(79.71 minutes vs.59.07 minutes,P<0.001),bleeding volume(839.64 mL vs.597.83 mL,P=0.001),and hospitalization cost(56 508.15 yuan vs.41 702.85 yuan,P<0.001)were significantly higher in the total hip arthroplasty group.However,the mortality rate was lower in the total hip arthroplasty group than in the hemiarthroplasty group(36%vs.57%,HR=0.44,95%CI:0.23-0.87,P=0.018),and the mean survival time was longer in the total hip arthroplasty group than in the hemiarthroplasty group(59.4 months vs.43.7 months,P=0.024).(3)There were no statistically significant differences in postoperative hospitalization time,preoperative and postoperative nutritional indicators,and overall postoperative complication rate between the two groups(P>0.05).However,in terms of postoperative pain,the incidence of pain was significantly higher in the hemiarthroplasty group than that in the total hip arthroplasty group(24%vs.7%,P=0.035).(4)Overall,total hip arthroplasty has a better prognosis for survival,while hemiarthroplasty is more appropriate for patients with poor physical fitness.At the same time,postoperative pain may largely affect the quality and survival time of patients after hip arthroplasty.

OBJECTIVE: A prospective randomized controlled study was conducted to investigate the early postoperative analgesic effectiveness of using liposomal bupivacaine (LB) for local infiltration anesthesia (LIA) in unicompartmental knee arthroplasty (UKA). METHODS: Between January 2024 and July 2024, a total of 80 patients with knee osteoarthritis (KOA) who met the selection criteria were enrolled in the study. Patients were randomly assigned to either the LB group or the "cocktail" group in a 1∶1 ratio using a random number table, with 40 patients in each group. Baseline characteristics, including gender, age, body mass index, operated side, Kellgren-Lawrence grade, and preoperative American Society of Anesthesiologists (ASA) classification, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint range of motion, showed no significant difference between the two groups ( P>0.05). Both groups received LIA and comprehensive pain management. The surgical duration, incision length, pain-related indicators [resting and activity visual analogue scale (VAS) scores, total dosage of oral morphine, WOMAC scores], knee joint range of motion, first ambulation time after operation, length of hospital stay, and postoperative adverse events. RESULTS: There was no significant difference between the two groups in surgical duration, incision length, first ambulation time after operation, length of hospital stay, total dosage of oral morphine, and pre-discharge satisfaction with surgery and WOMAC scores ( P>0.05). At 4, 12, and 24 hours after operation, the resting and activity VAS scores in the "cocktail" group were lower than those in the LB group; at 60 and 72 hours postoperatively, the resting VAS scores in the LB group were lower than those in the "cocktail" group, with the activity VAS scores also being lower at 60 hours; all showing significant differences ( P<0.05). There was no significant difference in the above indicators between the two groups at other time points ( P>0.05). On the second postoperative day, the sleep scores of the LB group were significantly higher than those of the "cocktail" group ( P<0.05), while there was no significant difference in sleep scores on the day of surgery and the first postoperative day ( P>0.05). Additionally, the incidence of complications showed no significant difference between the two groups ( P>0.05). CONCLUSION The use of LB for LIA in UKA can provide prolonged postoperative pain relief; however, it does not demonstrate a significant advantage over the "cocktail" method in terms of short-term analgesic effects or reducing opioid consumption and early functional recovery after UKA. Nevertheless, LB may help reduce postoperative sleep disturbances, making it a recommended option for UKA patients with cardiovascular diseases and insomnia or other mental health issues.

Objective:To analyze the benefit incidence and evaluate the implementation effects on catastrophic disease insurance under the New Rural Cooperative Medical System ( NRCMS) in Jilin Province and put forward sug-gestions to perfect the catastrophic disease insurance under NRCMS. Method: In-depth interviews with related staff were conducted to gain an understanding of the operating status of catastrophic disease insurance under NRCMS;cat-astrophic disease patient data of Jilin Province from 2013 were collected, with a comparative analysis of implementa-tion effects among nine districts;the benefit incidence was analyzed by means of the Sperman rank correlation analy-sis; Results: The policy of catastrophic disease insurance under the NRCMS exhibited sound implementation effects and played an important role in reducing the economic burden of catastrophic disease patients. The average individual expenditure decreased by 4336. 52 yuan, while the reimbursement rate increased by 11. 15% after NRCMS cata-strophic disease insurance reimbursements. Additionally, statistical analysis results showed that there was a weak cor-relation between benefit incidence and economic level, the benefit equality of catastrophic disease insurance under NRCMS was relatively good, but the benefit level of rich patients was slightly higher. Conclusion:The reimbursement scheme of catastrophic disease insurance under NRCMS should be refined and improved, and the benefit fairness of different districts must be ensured, thus achieving the goal of relieving the“poverty caused by illness” phenomenon.

Objective To summarize the technique and clinical experience of hybrid procedure under cardiopulmonary bypass (CPB) in children with muscular ventricular septal defect (mVSD). Methods From January 2006 to June 2010, 45 cases of mVSD underwent hybrid procedure with CPB. mVSDs were closed with devices under direct vision in 45 cases. Of them, there were 20 males and 25 females. They ranged from 52 days to 12 years [mean (2.05 ±2.48) year] in age and from 3 to 30 kg [(11.93 ±7.70)kg] in body weight. Preoperatively, most of children were highly susceptible to respiratory tract infections. The hybrid approach was used in all patients with CPB under the guidance of transesophageal echocardiography (TEE). The diameter of mVSDs ranged from 2 to 7 mm under TEE. Of 45 cases, 40 patients had increased rates of pulmonary blood flow. 29 patients had left axis deviation and 12 cases had sinus arrhythmia on electrocardiography (ECG). 19 had other congenital heart lesions, including transposition of great arteries in 1 case, tetralogy of Fallot in 2, pulmonary artery stenosis in 3, patent ductus arteriosus in 6, atrial septal defects in 6) and aorta coactation in 1. The quantity of VSDs were from 1 to 7 (single, in 7; two, in 24 case; three, in 8 case; four, in 5 case and seven, in lease. 37 patients were combined with pulmonary hypertension in our cohort. 38 patients with another large VSD and 19 with other congenital heart lesions were required surgical repair at sometime. Results The hybrid procedures were undertaken in all 45 cases of this cohort. All cases were successful and no deaths occurred during operation. A total of 48 devices were implanted in 45 patients, including single devices in 42 cases (device size ranged from 4 to 10 mm) and two devices in 3 cases (device size ranged from 4 -7 mm). The average time on CPB was (58.28 ±20.70) min , while aortic crossclamp time was(34. 94 ± 14.75) min. In addition, the time on mechanical ventilation postoperatively ranged from 2 hours to 6 days. Compared to the older children, 20 infante aged less than 8 monhad a significant difference in cardiac function in the early postoperative period. One infant was given up treatment because of serious infection. Anather cases recovered with the use of supportive treatment, such as using vasoactive agents, digoxin, inhaling nitric oxide, diuresis, and so on. The enteric-coated aspirin was given at dose of 5 mg ? kg -1. day -1 for a period of 3 to 6 months as usual postoperatively. All patients attended follow-up at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years post-procedure. No major complications were encountered during this period. All cases were no instance of migration of any of the devices, residual shunt, aortic regurgitation, atrioventricular valve dysfunction, Ⅲo atrial-ventricular conduction block, new arrhythmia, and so on. There are no death in long-term follow-up. Conclusion Hybrid procedure is safe and effective for the closure of congenital heart defects in children.
