| 1 | Signaling pathways and targeted therapy for myocardial infarction显示文摘Although the treatment of myocardial infarction(MI)has improved considerably,it is still a worldwide disease with high morbidity and high mortality.Whilst there is still a long way to go for discovering ideal treatments,therapeutic strategies committed to cardioprotection and cardiac repair following cardiac ischemia are emerging.Evidence of pathological characteristics in MI illustrates cell signaling pathways that participate in the survival,proliferation,apoptosis,autophagy of cardiomyocytes,endothelial cells,fibroblasts,monocytes,and stem cells.These signaling pathways include the key players in inflammation response,e.g.,NLRP3/caspase-1 and TLR4/MyD88/NF-κB;the crucial mediators in oxidative stress and apoptosis,for instance,Notch,Hippo/YAP,RhoA/ROCK,Nrf2/HO-1,and Sonic hedgehog;the controller of myocardial fibrosis such as TGF-β/SMADs and Wnt/β-catenin;and the main regulator of angiogenesis,PI3K/Akt,MAPK,JAK/STAT,Sonic hedgehog,etc.Since signaling pathways play an important role in administering the process of MI,aiming at targeting these aberrant signaling pathways and improving the pathological manifestations in MI is indispensable and promising.Hence,drug therapy,gene therapy,protein therapy,cell therapy,and exosome therapy have been emerging and are known as novel therapies.In this review,we summarize the therapeutic strategies for MI by regulating these associated pathways,which contribute to inhibiting cardiomyocytes death,attenuating inflammation,enhancing angiogenesis,etc.so as to repair and re-functionalize damaged hearts. | Qing Zhang Lu Wang Shiqi Wang Hongxin Cheng Lin Xu Gaiqin Pei Yang Wang Chenying Fu Yangfu Jiang Chengqi He Quan Wei | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 11 |
| 2 | Sialic acid-engineered mesoporous polydopamine nanoparticles loaded with SPIO and Fe3+as a novel theranostic agent for T1/T2 dual-mode MRI-guided combined chemo-photothermal treatment of hepatic cancer显示文摘diagnostic and therapeutic capability are highly needed for the treatment of hepatic cancer.Herein,we aimed to develop a novel mesoporous polydopamine(MPDA)-based theranostic agent for T1/T2 dual magnetic resonance imaging(MRI)-guided cancer chemo-photothermal therapy.Superparamagnetic iron oxide(SPIO)-loaded MPDA NPs(MPDA@SPIO)was firstly prepared,followed by modifying with a targeted molecule of sialic acid(SA)and chelating with Fe^(3+)(SA-MPDA@SPIO/Fe^(3+) NPs).After that,doxorubicin(DOX)-loaded SA-MPDA@SPIO/Fe^(3+) NPs(SA-MPDA@SPIO/DOX/Fe^(3+))was prepared for tumor theranostics.The prepared SAPEG-MPDA@SPIO/Fe^(3+) NPs were water-dispersible and biocompatible as evidenced by MTT assay.In vitro photothermal and relaxivity property suggested that the novel theranostic agent possessed excellent photothermal conversion capability and photostability,with relaxivity of being r1=4.29 mM��1s��1 and r2=105.53 mM��1s��1,respectively.SAPEG-MPDA@SPIO/Fe^(3+) NPs could effectively encapsulate the DOX,showing dual pH-and thermal-triggered drug release behavior.In vitro and in vivo studies revealed that SA-MPDA@SPIO/DOX/Fe^(3+) NPs could effectively target to the hepatic tumor tissue,which was possibly due to the specific interaction between SA and the overexpressed E-selectin.This behavior also endowed SA-MPDA@SPIO/DOX/Fe^(3+)NPs with a more precise T1-T2 dual mode contrast imaging effect than the one without SA modification.In addition,SAPEG-MPDA@SPIO/DOX/Fe^(3+) NPs displayed a superior therapeutic effect,which was due to its active targeting ability and combined effects of chemotherapy and photothermal therapy.These results demonstrated that SAPEG-MPDA@SPIO/DOX/Fe^(3+) NPs is an effective targeted nanoplatform for tumor theranostics,having potential value in the effective treatment of hepatic cancer. | Gaofeng Shu Minjiang Chen Jingjing Song Xiaoling Xu Chenying Lu Yuyin Du Min Xu Zhongwei Zhao Minxia Zhu Kai Fan Xiaoxi Fan Shiji Fang Bufu Tang Yiyang Dai Yongzhong Du Jiansong Ji | 2021 | Bioactive Materials2021，6，5： | 4 |

| 7 | Fucoidan-based dual-targeting mesoporous polydopamine for enhanced MRI-guided chemo-photothermal therapy of HCC via P-selectin-mediated drug delivery显示文摘The development of novel theranostic agents with outstanding diagnostic and therapeutic performances is still strongly desired in the treatment of hepatocellular carcinoma(HCC).Here,a fucoidan-modified mesoporous polydopamine nanoparticle dual-loaded with gadolinium iron and doxorubicin(FMPDA/Gd^(3+)/DOX)was prepared as an effective theranostic agent for magnetic resonance imaging(MRI)-guided chemo-photothermal therapy of HCC.It was found that FMPDA/Gd^(3+)/DOX had a high photothermal conversion efficiency of 33.4%and excellent T1-MRI performance with a longitudinal relaxivity(r1)value of 14.966 m M^(-1)·s^(-1).Moreover,the results suggested that FMPDA/Gd^(3+)/DOX could effectively accumulate into the tumor foci by dual-targeting the tumor-infiltrated platelets and HCC cells,which resulted from the specific interaction between fucoidan and overexpressed p-selectin receptors.The excellent tumor-homing ability and MRI-guided chemo-photothermal therapy therefore endowed FMPDA/Gd^(3+)/DOX with a strongest ability to inhibit tumor growth than the respective single treatment modality.Overall,our study demonstrated that FMPDA/Gd^(3+)/DOX could be applied as a potential nanoplatform for safe and effective cancer theranostics. | Gaofeng Shu Lin Shen Jiayi Ding Junchao Yu Xiaoxiao Chen Xiaoju Guo Enqi Qiao Yaning Chen Chenying Lu Zhongwei Zhao Yongzhong Du Minjiang Chen Jiansong Ji | 2022 | Asian Journal of Pharmaceutical Sciences2022，17，6： | 0 |

| 9 | Retrospective Analysis of the Duration of Hospitalization of Imported Patients Infected with SARS-CoV-2 in Guangzhou, 2021显示文摘The pandemic of coronavirus disease 2019 is“not over,”in fact,the“dynamic clearing”policy for SARS-CoV-2 control and prevention in China has been firmly enforced.This study aimed to analyze the clinical symptoms and dynamic viral RNA changes in 2021 at Guangzhou Eighth People’s Hospital.This study showed that 31.4%of the patients(695/2212)tested negative for viral RNA from admission to the final release from quarantine.Of all negative cases,86.5%(601/695)remained in the hospital for no more than 5 days and were asymptomatic or mild.Among the remaining 402 patients who stayed for no more than 5 days,76.4%(307/402)were viral RNA retest positive during the isolation stage.However,96.4%of the peak viral RNA(296/307)was over Ct=33 cycles during the isolation stage. | Zhiwei Xie Guofang Tang Lu Li Jingrong Shi Qingxin Gan Xiaowen Zheng Jingyan Tang Huimin Zeng Chuyu Zhang Sisi Cheni Jianping Cui Zishi Lin Lihua Lin Youxia Li Jinxin Liu Feng Li Fengyu Hui Xiaoping Tang Xilong Deng | 2023 | Infectious Diseases & Immunity2023，3，1： | 0 |
