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.

Objective:To preliminarily explore the application of directional electrodes with perceivable subthalamic nucleus-deep brain stimulation (STN-DBS) for Parkinson′s disease (PD).Methods:A retrospective analysis was conducted on 56 patients with primary PD who underwent STN-DBS treatment across multiple neurosurgical centers, including the Department of Neurosurgery of the First Medical Center of the Chinese People′s Liberation Army General Hospital, the Department of Neurosurgery of Hua′an Brain Hospital Affiliated to Anhui Medical University, and the Department of Neurosurgery of Hefei Second People′s Hospital, from January to December 2024. The cohort included 26 patients in the directional+perception group and 30 in the conventional group. The directional+perception group had activation contacts selected based on electrode branch contact locations and local field potential data recorded by the perceptible deep brain stimulation (DBS) system. The conventional group used contact testing to determine therapeutic contacts. Unified Parkinson′s Disease Rating Scale-Ⅲ (UPDRS-Ⅲ) assessments were performed in the medication-off state under continuous STN-DBS therapy at postoperative activation, 1, 3, and 6 months, comparing postoperative data with preoperative baseline. Initial programming outcomes were also compared between groups.Results:By combining directional electrodes with sensing capabilities, therapeutic contacts can be selected more quickly and effectively. The directional+ perception group showed significantly shorter initial programming time compared to the conventional group [(30.1±4.7) min vs (65.0±6.8) min, respectively], with a statistically significant difference ( t=-22.159, P<0.001). Compared to preoperative baseline, UPDRS-Ⅲ scores improved markedly at postoperative activation and at 1, 3, and 6 months, with improvements of 59.8%(20.6±5.2 vs 51.2±8.7), 62.1%(19.4±6.2 vs 51.2±8.7), 55.5%(22.8±7.2 vs 51.2±8.7), and 61.7%(19.6±13.9 vs 51.2±8.7), respectively. The scores of tremor showed the greatest improvement of 72.2% [2.5(0, 4.3) vs 9.0(0, 13.0)], 61.1% [3.5(0, 5.0) vs 9.0(0, 13.0)], 72.2% [2.5(0, 5.0) vs 9.0(0, 13.0)], 63.3% [0(0, 3.3) vs 9.0(0, 13.0)], respectively, followed by rigidity. Axial symptoms, postural stability, and gait improved moderately, while speech showed no significant change. Conclusions:In the treatment of PD, the combined use of directional electrodes and a perceivable DBS system allows precise selection of therapeutic contacts. This approach not only safely and effectively improves patients′ motor symptoms but also significantly reduces the time required for initial programming compared to conventional DBS systems, demonstrating clear clinical advantages.

Objective:To compare suture-button, absorbable screws (AS), and metal screws (MS) in the fixation of ankle fracture complicated with distal tibiofibular syndesmosis injury.Methods:A retrospective study was conducted to analyze the 71 patients with ankle fracture and distal tibiofibular syndesmosis injury who had been treated at Department of Foot and Ankle Surgery, Guangzhou Orthopedics Hospital from February 2020 to February 2023. There were 27 males and 44 females with an age of (49.6±10.3) years. The patients were assigned into 3 groups according to different treatment methods: a suture-button group in which 32 cases were treated with suture-button, an AS group in which 24 cases were treated with AS, and a MS group in which 15 cases were treated with MS to be removed at 8 to 12 weeks after operation. The 3 groups were compared in terms of intraoperative blood loss, operation time, and ankle range of motion, tibiofibular clear space (TFCS), and tibio-fibular overlap (TFOL) at the last follow-up, as well as American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at 3 months after operation and at the last follow-up.Results:There was no significant difference in the preoperative general data between the 3 groups, indicating comparability ( P>0.05). There were no significant differences in intraoperative blood loss, operation time, ankle range of motion, TFCS or TFOL between the 3 groups ( P>0.05). TFCS and TFOL at the last follow-up in all patients were significantly improved compared with those before operation ( P<0.05). The AOFAS ankle-hindfoot scores and VAS pain scores in the suture-button group and the AS group at 3 months after operation were significantly better than those in the MS group ( P<0.05). There was no significant difference in AOFAS ankle-hindfoot score or VAS pain score between the 3 groups at the last follow-up ( P>0.05). In all patients, the AOFAS ankle-hindfoot score and VAS pain score at the last follow-up were significantly better than those at 3 months after operation which were significantly better than those before operation ( P<0.05). Conclusions:In the fixation of ankle fracture complicated with distal tibiofibular syndesmosis injury, suture-button, AS and MS can all achieve definite clinical efficacy. As fixation with MS requires secondary surgical removal, its early functional score and pain score may be relatively poorer.

Rabies is an acute infectious disease caused by rabies virus with a high fatality rate. Post-exposure human rabies vaccination is an important measure to reduce the risk of rabies. Rabies vaccine is mainly used for post-exposure immunization with safety and tolerance. However, adverse reactions may occur in some recipients, mainly including local reactions such as pain, redness and swelling, and systemic reactions such as fever and headache. Usually, the symptoms are mild and self-limited, but severe adverse reactions in allergic patients may be life-threatening. The occurrence of adverse reactions to rabies vaccine for human use is closely related to individual differences, vaccine production process, and vaccination factors. The articles on adverse reaction of rabies vaccine for human use published in CNKI and PubMed database from 2006 to 2024 were retrieved. The incidence, causes and countermeasures of adverse reaction of rabies vaccine for human use were reviewed, so as to provide reference for reducing adverse reactions of rabies vaccine.

AIM:This study investigated the role of solute carrier family 7 member 11(SLC7A11)in sul-fasalazine(SAS)-induced ferroptosis in acute myeloid leukemia(AML)cells,focusing on the inhibitory effect of nuclear factor E2-related factor 2(NRF2)nuclear translocation-mediated activation of SLC7A11 on ferroptosis and its underlying mechanisms.METHODS:SAS-induced proliferation in AML cell lines,Kasumi-1 and THP-1,was assessed using the MTS assay.Cell death inhibitors were employed to determine the mode of cell death.Lipid reactive oxygen species(ROS)levels were measured by flow cytometry;Fe2+,malonodialdehyde(MDA),glutathione(GSH)levels,and glutathione per-oxidase 4(GPX4)activity were assessed using micromethods.Quantitative PCR(qPCR)was performed to evaluate changes in SLC7A11 mRNA during SAS-induced ferroptosis,while Western blot measured SLC7A11 and GPX4 protein levels.Moreover,Western blot assessed NRF2 nuclear translocation post-SAS treatment.The NRF2 inhibitor ML385 was used to validate these effects.SLC7A11 mRNA and protein levels were then measured following combined SAS and ML385 treatment via qPCR and Western blot.Cell viability and ferroptosis-related indices were evaluated under the same treatment conditions.Furthermore,a shRNA vector targeting SLC7A11 was constructed to assess changes in cell viability and ferroptosis markers after SLC7A11 knockdown with SAS.GPX4 protein levels were examined following SLC7A11 knockdown.RESULTS:SAS significantly inhibited the proliferation of Kasumi-1 and THP-1 cells at 200 μmol/L and 300 μmol/L,respectively(P<0.05).Only ferroptosis inhibitors(Fer-1 and DFO)significantly reversed SAS-induced cy-totoxicity(P<0.01).SAS increased lipid ROS,Fe2+,and MDA levels(P<0.01),while reducing GSH and GPX4 activity(P<0.01).The mRNA and protein expressions of SLC7A11 increased during SAS-induced ferroptosis(P<0.01),where-as GPX4 protein decreased significantly(P<0.01).SAS significantly increased the nuclear-to-cytoplasmic NRF2 ratio(P<0.01),which decreased upon co-treatment with ML385(P<0.05).Following SAS and ML385 co-treatment,both SLC7A11 mRNA and protein levels were downregulated(P<0.01).This combination treatment further reduced AML cell viability(P<0.01),an effect reversed by Fer-1 and DFO(P<0.01).Compared with SAS alone,the combination of SAS and ML385 significantly increased lipid ROS,Fe2+,and MDA while reducing GSH levels and GPX4 activity(P<0.01).SLC7A11 knockdown was successfully achieved.Compared with the NC shRNA group,SLC7A11 knockdown cells showed significantly decreased viability after SAS treatment,which was reversed by Fer-1 and DFO(P<0.01).Lipid ROS,Fe2+,and MDA content were significantly increased(P<0.01),and GSH and GPX4 were substantially decreased(P<0.05).Moreover,GPX4 protein expression was considerably reduced after SLC7A11 knockdown(P<0.01).CONCLUSION:SAS induces ferroptosis in AML cells.It promotes the nuclear translocation of NRF2 protein,which activates SLC7A11 ex-pression.Inhibition of NRF2 or downregulation of SLC7A11 sensitizes AML cells to SAS-induced ferroptosis.

OBJECTIVE To explore the clinical efficacy and possible mechanism of the classic prescription Xinyi Powder in the treatment of allergic rhinitis with lung deficiency related cold.METHODS A total of 189 patients who met the inclusion criteria of al-lergic rhinitis with lung deficiency related cold in the otolaryngology clinic of Jiangsu Province Hospital of Chinese Medicine from Janu-ary 2023 to July 2024 were selected and randomly divided into the experimental group(n=126)and the control group(n=63).The control group was treated with oral loratadine,and the experimental group took Xinyi Powder.Before and after treatment,the TNSS,TNNSS scores and TCM syndrome scores of the two groups of patients were compared to comprehensively evaluate the clinical efficacy.The changes in the patients'quality of life were evaluated in multiple dimensions using nasal VAS and RQLQ scores.The changes in serum IL-4,IL-5,IgE,SP and CGRP expression levels were detected by ELISA.RESULTS After 14 days of treatment,the TNSS,TNNSS,VAS,RQLQ scores and TCM syndrome scores of the two groups of patients were reduced(P<0.01);the experi-mental group was better than the control group in improving the concomitant symptoms such as nasal congestion,runny nose,postnasal drip,and itchy eyes(P<0.05,P<0.01),and it could also significantly improve the symptoms of fear of wind and cold,spontaneous sweating,shortness of breath,and cough with thin sputum(P<0.01),and the total RQLQ score was significantly better than the con-trol group(P<0.01).After treatment,the serum IL-4,IL-5,IgE,SP,and CGRP levels of the two groups of patients were signifi-cantly reduced(P<0.01),and there was no statistical difference between the two groups.CONCLUSION Xinyi Powder can signifi-cantly alleviate the nasal symptoms and systemic concomitant symptoms of patients with allergic rhinitis of lung deficiency and cold type,and significantly improve the quality of life of patients.It may play a therapeutic role by inhibiting the expression of inflammatory factors and neuropeptides and regulating neuroimmunity.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

Objective To design and synthesize dual-target antidepressant compounds possessing high-affinity binding to the serotonin 1A receptor(5-HT1A)and dual-site synergistic inhibition of the serotonin transporter(SERT).Methods Based on a dual-target synergistic mechanism,benzodioxolane derivatives were designed via scaffold hopping strategy before being synthesized.Their binding affinities to both targets were determined via competitive radioligand binding assays,and their binding modes were investigated using molecular docking.Results Eleven structurally novel target compounds were synthesized and structurally characterized by electrospray ionization mass spectrometry(ESI-MS)and nuclear magnetic resonance(NMR)spectroscopy.Compound 18b demonstrated dual nanomolar affinity for both the 5-HT1A receptor(Ki=2.72 nmol/L)and SERT(Ki=8.85 nmol/L).Molecular docking revealed that its inhibitory effect on SERT resulted from simultaneous occupation of the orthosteric site S1(Asp98 salt bridge)and the allosteric site S2(Arg104 rr-cation interaction),while its high affinity for 5-HT1A depended on the Asp116332 salt bridge anchor and π-π stacking with Phe362652.Conclusion The benzodioxolane-scaffold compounds designed and synthesized in this study exhibited functional synergy between simultaneous occupation of both the S1 and S2 sites of SERT and high-affinity binding to the 5-HT1Areceptor.Among them,compound 18b demonstrates superior activity and promises to be a lead compound for more investigation.

Objective:To evaluate the accuracy and safety profile of a novel cuboid orientation-guided frontal horn ventriculostomy technique in patients with large hemispheric infarction (LHI).Methods:It was conducted a retrospective cohort study of 48 consecutive LHI patients who underwent the innovative ventriculostomy procedure between time period. Primary outcomes included procedural accuracy (success rates, catheter positioning) and safety indicators (complication rates).Results:All the punctured ventricles were small or of normal size. The success rate of puncture was 100%, the success rate of one-time puncture was 87% (42/48), and the average number of puncture was 1.13 times per case. The ratio of well-positioned tube heads was 87.5% (42/48). The actual angle of the inward deviation of the puncture ranged from -2o to 5o, with an average of 0o±0.3o. The depth of puncture was 7.0-8.0 cm ( 7.3±0.3) cm. The incidence of bleeding around the puncture path was 1.3% (2/48 ) and no massive bleeding occurred. At the 6-month follow-up, one case (2.94%) among the 34 survivors had epilepsy.Conclusions:The cuboid orientation-guided frontal horn ventriculostomy technique demonstrates exceptional procedural accuracy and an excellent safety profile in LHI patients, with high first-pass success rates (87.5%) and minimal complications (4.2% minor hemorrhage). These findings support its clinical adoption for this patient population.

Objective:To explore the advantages of robotic-arm assisted total hip arthroplasty (rTHA) in acetabular component positioning and lower limb length assessment in patients with severe pelvic coronal tilt.Methods:A retrospective analysis was conducted on the data of 122 patients with unilateral end-stage hip disease and coronal pelvic tilt angle >3° who underwent total hip arthroplasty (THA) at the First Medical Center of PLA General Hospital from June 2022 to December 2023. Among them, 44 patients underwent rTHA, and 78 underwent manual THA (mTHA). The rTHA group included 18 males and 26 females, with an average age of 60.5±9.3 years; the mTHA group included 41 males and 37 females, with an average age of 58.5±8.4 years. Compare the differences in the anteversion angle, abduction angle, pelvic tilt angle, leg length discrepancy (LLD) of the acetabular prosthesis, and the proportions of patients with LLD>0.5 cm and >1 cm between the two groups of patients after surgery. Calculate the proportion of outlier rates of acetabular abduction angle (<30° or >45°), and proportions within Callanan's safe zone. The early efficacy of the hip joint was evaluated by using the modified Harris score and joint range of motion.Results:All patients were followed up for 6 to 12 months, with an average of 8 months. All the surgical incisions of the patients achieved primary healing. Postoperative comparisons showed no statistically significant differences in acetabular abduction angle (39.5°±3.3° vs. 38.4°±7.3°) or anteversion angle (20.7°±1.6° vs. 19.7°±1.6°) between rTHA and mTHA groups ( P>0.05). However, pelvic tilt angle [2.5° (1.1°, 3.6°) vs. 3.5° (2.3°, 5.9°)] showed a statistically significant difference ( U=4.371, P=0.008). The rTHA group exhibited smaller absolute LLD [0.2 (0.1, 0.4) cm vs. 0.5 (0.2, 0.5) cm] and lower proportions of LLD >0.5 cm [14% (6/44) vs. 49% (38/78)] and >1 cm [2% (1/44) vs. 18% (14/78)], with statistical significance ( P<0.05). The rTHA group had a lower outlier rate for acetabular abduction angle (<30°or >45°) compared to the mTHA group [2% (1/44) vs. 33% (26/78)], with statistical significance (χ 2=10.388, P<0.001). Taking the Callanan safety zone as the standard, the proportion of acetabular cups within the safe zone was significantly higher in the rTHA group (98%, 43/44) compared to the mTHA group (67%, 52/78), with a statistically significant difference (χ 2=13.998, P<0.001). The modified Harris score and hip joint range of motion in the mTHA group increased from 47.6±6.6 points and 83° (73°, 88°) before the operation to 83.5±11.2 points and 118° (110°, 122°) at the last follow-up, respectively. The rTHA group increased from 46.5±9.2 points and 79° (71°, 90°) before the operation to 85.0±12.5 points and 124° (116°, 130°) at the last follow-up. The differences in the modified Harris score and hip joint range of motion between the two groups before the operation and at the last follow-up were statistically significant ( P<0.05). However, there was no statistically significant difference between the groups at the last follow-up ( P>0.05). No THA-related complications occurred during follow-up period. Conclusion:For patients with end-stage hip joint diseases with coronal tilt exceeding 3°, robotic-assisted technology significantly improves the accuracy of acetabular component placement during THA and offers better control of postoperative LLD.
