    • 摘要: Postoperative cognitive dysfunction(POCD)is a common surgical complication.Diabetes mellitus(DM)increases risk of developing POCD after surgery.DM patients with POCD seriously threaten the quality of patients’life,however,the intrinsic mechanism is unclear,and the effective treatment is deficiency.Previous studies have demonstrated neuronal loss and reduced neurogenesis in the hippocampus in mouse models of POCD.In this study,we constructed a mouse model of DM by intraperitoneal injection of streptozotocin,and then induced postoperative cognitive dysfunction by transient bilateral common carotid artery occlusion.We found that mouse models of DM-POCD exhibited the most serious cognitive impairment,as well as the most hippocampal neural stem cells(H-NSCs)loss and neurogenesis decline.Subsequently,we hypothesized that small extracellular vesicles secreted by induced pluripotent stem cell-derived mesenchymal stem cells(iMSC-sEVs)might promote neurogenesis and restore cognitive function in patients with DM-POCD.iMSC-sEVs were administered via the tail vein beginning on day 2 after surgery,and then once every 3 days for 1 month thereafter.Our results showed that iMSC-sEVs treatment significantly recovered compromised proliferation and neuronal-differentiation capacity in H-NSCs,and reversed cognitive impairment in mouse models of DM-POCD.Furthermore,miRNA sequencing and qPCR showed miR-21-5p and miR-486-5p were the highest expression in iMSC-sEVs.We found iMSC-sEVs mainly transferred miR-21-5p and miR-486-5p to promote H-NSCs proliferation and neurogenesis.As miR-21-5p was demonstrated to directly targete Epha4 and CDKN2C,while miR-486-5p can inhibit FoxO1 in NSCs.We then demonstrated iMSC-sEVs can transfer miR-21-5p and miR-486-5p to inhibit EphA4,CDKN2C,and FoxO1 expression in H-NSCs.Collectively,these results indicate significant H-NSC loss and neurogenesis reduction lead to DM-POCD,the application of iMSC-sEVs may represent a novel cell-free therapeutic tool for diabetic patients with postoperative cognitive dysfunction.

    • 摘要: The functional properties of endogenous Schwann cells(SCs)during nerve repair are dynamic.Optimizing the functional properties of SCs at different stages of nerve repair may have therapeutic benefit in improving the repair of damaged nerves.Previous studies showed that miR-221-3p promotes the proliferation and migration of SCs,and miR-338-3p promotes the myelination of SCs.In this study,we established rat models of sciatic nerve injury by bridging the transected sciatic nerve with a silicone tube.We injected a miR-221 lentiviral vector system together with a doxycycline-inducible Tet-On miR-338 lentiviral vector system into the cavity of nerve conduits of nerve stumps to sequentially regulate the biological function of endogenous SCs at different stages of nerve regeneration.We found that the biological function of SCs was sequentially regulated,the diameter and density of myelinated axons were increased,the expression levels of NF200 and myelin basic protein were increased,and the function of injured peripheral nerve was improved using this system.miRNA Target Prediction Database prediction,Nanopore whole transcriptome sequencing,quantitative PCR,and dual luciferase reporter gene assay results predicted and verified Cdkn1b and Nrp1 as target genes of miR-221-3p and miR-338-3p,respectively,and their regulatory effects on SCs were confirmed in vitro.In conclusion,here we established a new method to enhance nerve regeneration through sequential regulation of biological functions of endogenous SCs,which establishes a new concept and model for the treatment of peripheral nerve injury.The findings from this study will provide direct guiding significance for clinical treatment of sciatic nerve injury.

    • 摘要: 背景:目前非编码RNA已被证实在多种骨科疾病中发挥重要作用,因此,非编码RNA可能为了解该疾病的病因、发病机制、治疗方法带来新的思路。目的:探索早期诊断、治疗股骨头坏死的方法和思路,综述非编码RNA在股骨头坏死中的研究进展,并提出目前所存在的问题及解决方法。方法:以“股骨头坏死,非编码RNA,miRNA,lncRNA,circRNA”为检索词检索中国知网、万方、维普等数据库,以“osteonecrosis of the femoral head,non-coding RNAs,miRNA,lncRNA,circRNA”为检索词检索PubMed、Medline等数据库,检索时限均为2000年1月至2021年11月。最终纳入67篇文献。结果与结论:(1)非编码RNA的种类非常丰富,大约占所有转录产物的98%,同时占所有RNA的90%左右,根据其功能可分为管家非编码RNA(如tRNA、rRNA、snoRNA)以及调节非编码RNA(如miRNA、lncRNA、circRNA、siRNA);(2)目前miRNAs与激素型股骨头坏死的研究逐渐成为热点,而外泌体lncRNAs、circRNAs与股骨头坏死的相关研究尚未见到报道;(3)多数非编码RNA在发生激素型股骨头坏死时表达下调,大部分非编码RNA通过负向调控其相关靶基因,以促进骨髓间充质干细胞增殖、成骨分化,促进成骨标记物的表达,也可以促进血管内皮细胞生成,从而抑制股骨头缺血性坏死的发生及进展;(4)外泌体携带的非编码RNA也可以在股骨头坏死中发生作用,但目前文献量较少,非编码RNA是否通过外泌体携带所产生的作用目前暂不清楚,在未来的研究中可逐渐完善;(5)利用非编码RNA类似物和抑制剂可以有效抑制非创伤性股骨头坏死的发生发展,可以为非创伤性股骨头坏死的早期诊断和治疗提供新的策略。

    • 摘要: 背景:早发性卵巢功能不全是临床上影响女性生殖健康的重要病因之一。近年来,随着再生医学的发展,许多学者认为间充质干细胞通过旁分泌途径分泌相关细胞因子(如外泌体和miRNA)改善卵巢间质微环境,促进卵巢组织修复。目的:总结外泌体及miRNA治疗早发性卵巢功能不全的研究进展,深入探究其存在的相关机制,为外泌体及miRNA治疗早发性卵巢功能不全的进一步研究和临床诊疗提供理论依据。方法:在CNKI和PubMed数据库检索自数据库建库至2022年6月期间的文献,中文检索词为“外泌体,miRNA,早发性卵巢功能不全,卵巢早衰”,英文检索词为“exosome,miRNA,ovary,premature ovarian failure,premature ovarian insufficiency”,排除研究目的与该综述不相关及重复的文献,将检索到的有关机制和诊疗的文献进行整理,共纳入63篇文献进行分析。结果与结论:①各类外泌体及miRNA对早发性卵巢功能不全的细胞、动物模型都有良好的治疗效果,具体机制包括促进增殖、影响凋亡、分泌激素、氧化应激和炎症反应等。②大量的临床前实验为临床诊疗提供理论依据,但临床试验仍处于起步阶段,其安全性和有效性需要进一步确认。外泌体在针刺治疗过程中发挥着重要作用,可以外泌体为切入点干预针刺靶向治病机制,以期进一步提高针刺治疗效果。③通过总结可以看出,外泌体及miRNA对于早发性卵巢功能不全的治疗作用往往不是只局限于某一方面,而是通过多种通路、多个靶点协同作用进而达到良好的治疗效果。

    • 摘要: MicroRNAs(miRNAs)play an important regulatory role in neuronal growth and development.Different mi RNAs target different genes to protect neurons in different ways,such as by avoiding apoptosis,preventing degeneration mediated by conditional mediators,preventing neuronal loss,weakening certain neurotoxic mechanisms,avoiding damage to neurons,and reducing inflammatory damage to them.The high expression of mi RNAs in the brain has significantly facilitated their development as protective targets for therapy,including neuroprotection and neuronal recovery.mi RNA is indispensable to the growth and development of neurons,and in turn,is beneficial for the development of the brain and checking the progression of various diseases of the nervous system.It can thus be used as an important therapeutic target for models of various diseases.This review provides an introduction to the protective effects of mi RNA on neurons in case of different diseases or damage models,and then provides reference values and reflections on the relevant treatments for the benefit of future research in the area.

    • 摘要: Exosome-derived long non-coding RNAs(lncRNAs)are extensively engaged in recovery and repair of the injured spinal cord,through different mechanisms.However,to date no study has systematically evaluated the differentially expressed lncRNAs involved in the development of spinal cord injury.Thus,the aim of this study was to identify key circulating exosome-derived lncRNAs in a rat model of spinal cord injury and investigate their potential actions.To this end,we established a rat model of spinal cord hemisection.Circulating exosomes were extracted from blood samples from spinal cord injury and control(sham)rats and further identified through Western blotting and electron microscopy.RNA was isolated from the exosomes and sequenced.The enrichment analysis demonstrated that there were distinctively different lncRNA and mRNA expression patterns between the two groups.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis and Gene Ontology(GO)functional analysis were performed to determine the possible involvements of upregulated and downregulated lncRNAs in various pathways and different biological processes,as well as their cellular locations and molecular functions.Furthermore,quantitative reverse transcription-polymerase chain reaction showed that the expression of five lncRNAs––ENSRN0T00000067908,XR_590093,XR_591455,XR_360081,and XR_346933––was increased,whereas the expression of XR_351404,XR_591426,XR_353833,XR_590076,and XR_590719 was decreased.Of note,these 10 lncRNAs were at the center of the lncRNA-miRNA-mRNA coexpression network,which also included 198 mRNAs and 41 miRNAs.Taken together,our findings show that several circulating exosomal lncRNAs are differentially expressed after spinal cord injury,suggesting that they may be involved in spinal cord injury pathology and pathogenesis.These lncRNAs could potentially serve as targets for the clinical diagnosis and treatment of spinal cord injury.
