| 1 | Stem cell-based therapy for human diseases显示文摘Recent advancements in stem cell technology open a new door for patients suffering from diseases and disorders that have yet to be treated.Stem cell-based therapy,including human pluripotent stem cells(hPsCs)and multipotent mesenchymal stem cells(MSCs),has recently emerged as a key player in regenerative medicine.hPSCs are defined as self-renewable cell types conferring the ability to differentiate into various cellular phenotypes of the human body,including three germ layers.MsCs are multipotent progenitor cells possessing self-renewal ability(limited in vitro)and differentiation potential into mesenchymal lineages,according to the International Society for Cell and Gene Therapy(ISCT).This review provides an update on recent clinical applications using either hPSCs or MSCs derived from bone marrow(BM),adipose tissue(AT),or the umbilical cord(UC)for the treatment of human diseases,including neurological disorders,pulmonary dysfunctions,metabolic/endocrine-related diseases,reproductive disorders,skin burns,and cardiovascular conditions.Moreover,we discuss our own clinical trial experiences on targeted therapies using MsCs in a clinical setting,and we propose and discuss the MSC tissue origin concept and how MSC origin may contribute to the role of MSCs in downstream applications,with the ultimate objective of facilitating translational research in regenerative medicine into clinical applications.The mechanisms discussed here support the proposed hypothesis that BM-MSCs are potentially good candidates for brain and spinal cord injury treatment,AT-MSCs are potentially good candidates for reproductive disorder treatment and skin regeneration,and UC-MsCs are potentially good candidates for pulmonary disease and acute respiratory distress svndrometreatment. | Duc M.Hoang Phuong T.Pham Trung Q.Bach Anh T.L.Ngo Quyen T.Nguyen Trang T.K.Phan Giang H.Nguyen Phuong T.T.Le Van T.Hoang Nicholas R.Forsyth Michael Heke Liem Thanh Nguyen | 2022 | Signal Transduction and Targeted Therapy2022，7，9： | 7 |

| 3 | Signaling pathways and targeted therapies for psoriasis显示文摘Psoriasis is a common,chronic,and inflammatory skin disease with a high burden on individuals,health systems,and society worldwide.With the immunological pathologies and pathogenesis of psoriasis becoming gradually revealed,the therapeutic approaches for this disease have gained revolutionary progress.Nevertheless,the mechanisms of less common forms of psoriasis remain elusive.Furthermore,severe adverse effects and the recurrence of disease upon treatment cessation should be noted and addressed during the treatment,which,however,has been rarely explored with the integration of preliminary findings.Therefore,it is crucial to have a comprehensive understanding of the mechanisms behind psoriasis pathogenesis,which might offer new insights for research and lead to more substantive progress in therapeutic approaches and expand clinical options for psoriasis treatment.In this review,we looked to briefly introduce the epidemiology,clinical subtypes,pathophysiology,and comorbidities of psoriasis and systematically discuss the signaling pathways involving extracellular cytokines and intracellular transmission,as well as the cross-talk between them.In the discussion,we also paid more attention to the potential metabolic and epigenetic mechanisms of psoriasis and the molecular mechanistic cascades related to its comorbidities.This review also outlined current treatment for psoriasis,especially targeted therapies and novel therapeutic strategies,as well as the potential mechanism of disease recurrence. | Jia Guo Hanyi Zhang Wenrui Lin Lixia Lu Juan Su Xiang Chen | 2023 | Signal Transduction and Targeted Therapy2023，8，12： | 0 |

| 6 | Danhong Injection Up-Regulates miR-125b in Endothelial Exosomes and Attenuates Apoptosis in Post-Infarction Myocardium显示文摘Objective:To investigate the involvement of endothelial cells(ECs)-derived exosomes in the antiapoptotic effect of Danhong Injection(DHI)and the mechanism of DHI-induced exosomal protection against postinfarction myocardial apoptosis.Methods:A mouse permanent myocardial infarction(MI)model was established,followed by a 14-day daily treatment with DHI,DHI plus GW4869(an exosomal inhibitor),or saline.Phosphatebuffered saline(PBS)-induced ECs-derived exosomes were isolated,analyzed by miRNA microarray and validated by droplet digital polymerase chain reaction(ddP CR).The exosomes induced by DHI(DHI-exo),PBS(PBS-exo),or DHI+GW4869(GW-exo)were isolated and injected into the peri-infarct zone following MI.The protective effects of DHI and DHI-exo on MI hearts were measured by echocardiography,Masson's trichrome staining,and TUNEL apoptosis assay.The Western blotting and quantitative reverse transcription PCR(qR T-PCR)were used to evaluate the expression levels of miR-125b/p53-mediated pathway components,including miR-125b,p53,Bak,Bax,and caspase-3 activities.Results:DHI significantly improved cardiac function and reduced infarct size in MI mice(P<0.01),which was abolished by the GW4869 intervention.DHI promoted the exosomal secretion in ECs(P<0.01).According to the results of exosomal miRNA microarray assay,30 differentially expressed miRNAs in the DHI-exo were identified(28 up-regulated miRNAs and 2 down-regulated miRNAs).Among them,DHI significantly elevated miR-125b level in DHI-exo and DHI-treated ECs,a recognized apoptotic inhibitor impeding p53 signaling(P<0.05).Remarkably,treatment with DHI and DHI-exo attenuated apoptosis,elevated miR-125b expression level,inhibited capsase-3 activity,and down-regulated the expression levels of proapoptotic effectors(p53,Bak,and Bax)in post-MI hearts,whereas these effects were blocked by GW4869(P<0.05 or P<0.01).Conclusion:DHI and DHI-induced exosomes inhibited apoptosis,promoted the miR-125b expression level,and regulated the p53 apoptotic pathway in post-infarction myocardium. | LI Si-nai LIU Zi-hao ZHOU Ming-xue LIU Wei-hong LAI Xiao-lei LI Ping ZHANG Lei SHANG Ju-ju QIU Sheng-lei LOU Yan TAN Yu-pei XING Wen-long LIU Hong-xu | 2023 | Chinese Journal of Integrative Medicine2023，29，12： | 0 |
| 7 | 芪参颗粒防治阿霉素所致心肌损伤的作用机制研究及实验验证显示文摘目的:基于网络药理学及实验研究,验证芪参颗粒(QSG)治疗阿霉素心肌损伤的作用机制。方法:在中药系统药理学数据库与分析平台(TCMSP)筛选QSG的活性成分及作用靶点,借助人类基因数据库(GeneCards)、在线人类孟德尔遗传数据库(OMIM)、遗传药理学与药物基因组学数据库(PharmGKB)等疾病数据库搜索阿霉素心肌损伤靶点,使用蛋白质相互作用分析数据库(STRING)数据库分析蛋白质-蛋白质相互作用(PPI)进行互作分析。利用Cytoscape构建网络,Hiplot数据库进行基因组百科全书(KEGG)富集分析。最后,通过实验对QSG的药效、靶点及通路进行验证。结果:QSG中共检索到174种化学成分,无重复靶点261个,疾病数据库共检索到1 521个无重基因,二者交集靶点为156个。PPI网络提取了排名前十的基因,大多与炎症反应相关。KEGG富集结果显示主要与促分裂原活化的蛋白激酶(MAPK)、磷脂酰肌醇3激酶/蛋白激酶B(PI3K/AKT)、verified by experi及癌症信号通路等相关。体内实验结果表明,QSG可明显提高小鼠的心功能,改善病理组织损伤并降低炎症细胞浸润,同时能显著提高磷酸化蛋白激酶B(p-AKT)并降低磷酸化促分裂原活化的蛋白激酶(p-MAPK)及磷酸化核因子κB(p-NF-κB)的表达。体外结果表明QSG可明显降低炎症介质的含量,且联合使用阿霉素时不会影响阿霉素本身的抗肿瘤效果。结论:QSG显示出良好的抗阿霉素心肌损伤作用,其机制可能与其抗炎作用相关。 | 张敬美 薛思明 李伟利 陈欢 卢令慧 王其艳 | 2023 | 世界中医药2023，18，20： | 0 |
