BACKGROUND Osteoarthritis(OA)is the most prevalent form of degenerative whole-joint *** the final option of knee replacement,arthroscopic surgery was the most widely used joint-preserving surgical *** regenerative therapies,such as those involving platelet-rich plasma,mesenchymal stem cells,and microfragmented adipose tissue(MFAT),have been pushed to the forefront of treatment to prevent the progression of ***,MFAT has been successfully applied to treat different types of orthopedic *** To assess the efficacy and safety of MFAT with arthroscopic surgery in patients with knee OA(KOA).METHODS A randomized,multicenter study was conducted between June 2017 and November 2022 in 10 hospitals in Zhejiang,***,302 patients diagnosed with KOA(Kellgren-Lawrence grades 2-3)were randomized to the MFAT group(n=151,were administered MFAT following arthroscopic surgery),or the control group(n=151,were administered hyaluronic acid following arthroscopic surgery).The study outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,the visual analog scale(VAS)score,the Lequesne index score,the Whole-Organ Magnetic Resonance Imaging Score(WORMS),and safety over a 24-mo period from *** The changes in the WOMAC score(including the three subscale scores),VAS pain score,and Lequesne index score at the 24-mo mark were significantly different in the MFAT and control groups,as well as when comparing values at the posttreatment visit and those at baseline(P<0.001).The MFAT group consistently demonstrated significant decreases in the WOMAC pain scores and VAS scores at all follow-ups compared to the control group(P<0.05).Furthermore,the WOMAC stiffness score,WOMAC function score,and Lequesne index score differed significantly between the groups at 12 and 24 mo(P<0.05).However,no signicant between-group differences were observed in the WORMS at 24 mo(P=0.367).No serious adverse events

人即刻早期反应基因2(immediate early response 2,IER2)可能参与肿瘤的发生发展,但它在此过程中的作用及表达调控的机制仍不清楚。本研究通过在线数据库GEPIA2与Kaplan-Meier Plotter分析发现:TNF和IER2基因在食管癌组织和宫颈癌组织中高表达。而且IER2基因高表达的食管癌病人的预后显著较差。通过UCSC基因组数据库分析发现,在宫颈癌细胞和淋巴细胞内,TNFα(由TNF基因编码)诱导激活NF-κB结合IER2基因区。qRT-PCR检测证明,在食管癌和宫颈癌等细胞内,TNFα诱导NF-κB在转录水平上调IER2基因的表达。本文据此提出,TNFα诱导NF-κB上调IER2基因的表达可能是其在食管癌和宫颈癌等肿瘤中高表达的调控机制。本研究还通过在线数据库GeneMANIA和String分析发现11个与IER2具有关联性的基因。通过在线数据库Oncomine分析发现了88个基因在食管癌细胞内与IER2基因共表达。其中,包含7个与IER2具有关联性的基因ATF3、DUSP1、EGR1、EGR2、FOSB、JUN、NR4A1。本研究通过Oncomine数据库分析证明,在前列腺癌组织细胞内,这7个基因也与IER2共表达。并通过qRT-PCR检测验证这7个基因在食管癌细胞内与IER2基因共表达。GO注释表明,IER2可能通过与ATF3、EGR1、JUN相互作用,协同参与细胞增殖等生物学过程。CCK8检测证明,IER2基因过表达促进食管癌细胞生长增殖。总之,本研究初步揭示了IER2在食管癌和宫颈癌中高表达的调控机制及其作用,为深入研究该基因功能提供了线索。
