| 1 | Isoliquiritigenin inhibits TGF-β1-induced fibrogenesis through activating autophagy via PI3K/AKT/mTOR pathway in MRC-5 cells显示文摘Isoliquiritigenin(ISL),a natural flavonoid derived from the root of liquorice,has been reported to possess anti-inflammatory and antioxidant activities.Previous studies have found that ISL plays a crucial role in anti-fibrosis of adipose tissue and renal tissue;however,its effect on pulmonary fibrogenesis has not been demonstrated.In this study,we aimed to explore the roles and the underlying mechanisms of ISL in TGF-β1-induced fibrogenesis using human lung fibroblast-derived MRC-5 cells.Cell proliferation and migration were determined by MTT and wound healing assay,respectively.The expression levels of alpha-smooth muscle actin(α-SMA),collagen type I alpha 1(COLIA1)and fibronectin(FN),microtubule-associated protein light chain 3(LC3)and related signaling molecules were detected by quantitative real-time PCR,western blot and immunofluorescence assay,correspondingly.EGFP-LC3 transfection was used for autophagy analysis.The results showed that ISL inhibited the TGF-β1-induced proliferation and migration,and down-regulated the expressions ofα-SMA,COLIA1 and FN.ISL treatment led to up-regulation of LC3 in TGF-β1-treated MRC-5 cells,accompanied by significant decrease in the phosphorylation levels of phosphatidylinositol 3-kinase(PI3K),protein kinase B(AKT),and mammalian target of rapamycin(mTOR).In addition,the inhibitory effects of ISL on TGF-β1-induced fibrogenic features in MRC-5 cells were enhanced by pretreatment with autophagy activator Rapmycin and PI3K/AKT inhibitor LY294002 and reversed by autophagy inhibitor 3-methyladenine and PI3K/AKT activator IGF-1.Taken together,our results demonstrated that ISL could attenuate the fibrogenesis of TGF-β1-treated MRC-5 cells by activating autophagy via suppressing the PI3K/AKT/mTOR pathway.Therefore,ISL holds a great potential to be developed as a novel therapeutic agent for the treatment of pulmonary fibrosis. | Jinjuan He Hao Peng Meifang Wang Ying Liu Xingrong Guo Bin Wang Longjun Dai Xueqin Cheng Zhongji Meng Leyong Yuan Fenglin Cai Yijun Tang | 2020 | Acta Biochimica et Biophysica Sinica2020,52,8: | 16 |
| 2 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021,3,21: | 16 |

| 4 | Regulation of Hepatitis C Virus Replication and Gene Expression by the MAPK-ERK Pathway显示文摘The mitogen activated protein kinases-extracellular signal regulated kinases (MAPK-ERK) pathway is involved in regulation of multiple cellular processes including the cell cycle. In the present study using a Huh7 cell line Con1 with an HCV replicon, we have shown that the MAPK-ERK pathway plays a significant role in the modulation of HCV replication and protein expression and might influence IFN-α signalling. Epithelial growth factor (EGF) was able to stimulate ERK activation and decreased HCV RNA load while a MAPK-ERK pathway inhibitor U0126 led to an elevated HCV RNA load and higher NS5A protein amounts in Con1 cells. It could be further demonstrated that the inhibition of the MAPK-ERK pathway facilitated the translation directed by the HCV internal ribosome entry site. Consistently, a U0126 treatment enhanced activity of the HCV reporter replicon in transient transfection assays. Thus, the MAPK-ERK pathway plays an important role in the regulation of HCV gene expression and replication. In addition, cyclin-dependent kinases (CDKs) downstream of ERK may also be involved in the modulation of HCV replication since roscovitine, an inhibitor of CDKs had a similar effect to that of U0126. Modulation of the cell cycle progression by cell cycle inhibitor or RNAi resulted consistently in changes of HCV RNA levels. Further, the replication of HCV replicon in Con1 cells was inhibited by IFN-α. The inhibitory effect of IFN-α could be partly reversed by pre-incubation of Con-1 cells with inhibitors of the MAPK-ERK pathway and CDKs. It could be shown that the MAPK-ERK inhibitors are able to partially modulate the expression of interferon-stimulated genes. | Rongjuan Pei Xiaoyong Zhang Song Xu Zhongji Meng Michael Roggendorf Mengji Lu Xinwen Chen | 2012 | Virologica Sinica2012,27,5: | 2 |
| 5 | Microstructural evolution and mechanical properties of binary Mg-xBi(x=2,5,and 8 wt%)alloys显示文摘The microstructures and mechanical properties of Mg-x Bi(x=2,5,and 8 wt%)were investigated compared with pure Mg.The ascast Mg-Bi billets consist of dendriticα-Mg grain matrix,divorced eutectic Mg_(3)Bi_(2) phase and secondary precipitated Mg_(3)Bi_(2) phase.After homogenization,secondary precipitated Mg_(3)Bi_(2) particles were all dissolved into the matrix,while most of the divorced eutectic Mg_(3)Bi_(2) intermetallic compounds retained.All the as-extruded samples exhibit fully dynamic recrystallization(DRX)and the average grain size decreases and the amount of nano-scale Mg_(3)Bi_(2) precipitates increases with increasing Bi content.Additionally,Bi alloying has little influence on the texture of the as-extruded pure Mg,with all the samples showing typical basal texture.As the results of grain refinement and precipitation hardening,the strengths of the as-extruded samples increase under both tensile and compressive tests.Besides,the yield asymmetry significantly decreases with Bi content.Moreover,all the as-extruded samples represent similar ductility under compression,while the tensile elongation first increases and then decreases with more Bi added.The as-extruded Mg-5Bi alloy demonstrates good combination of strength and ductility.However,Mg-8Bi alloy displays lower tensile ductility than that of Mg-5Bi alloy due to the presence of abundant undissolved coarse Mg_(3)Bi_(2) particles,which act as cracking sources during tensile test.Furthermore,the strain hardening rate,strain hardening exponent n,and hardening capacity Hc are greatly reduced by Bi addition,mainly owing to the enhanced synergy effects of grain refinement and numerous Mg_(3)Bi_(2) precipitates. | Hui Yu Shaoda Fan Shuaiju Meng Jae Ok Choi Zhongjie Li Yohan Go Young Min Kim Weimin Zhao Bong Sun You Kwang Seon Shin | 2021 | Journal of Magnesium and Alloys2021,9,3: | 1 |

| 7 | New Algorithm Rules Out Acute-on-chronic Liver Failure Development within 28 Days from Acute Decompensation of Cirrhosis显示文摘Background and Aims:Approximately 10%of patients with acute decompensated(AD)cirrhosis develop acute-on-chronic liver failure(ACLF)within 28 days.Such cases have high mortality and are difficult to predict.Therefore,we aimed to establish and validate an algorithm to identify these patients on hospitalization.Methods:Hospitalized patients with AD who developed ACLF within 28 days were considered pre-ACLF.Organ dysfunction was defined accord-ing to the chronic liver failure-sequential organ failure as-sessment(CLIF-SOFA)criteria,and proven bacterial infec-tion was taken to indicate immune system dysfunction.A retrospective multicenter cohort and prospective one were used to derive and to validate the potential algorithm,re-spectively.A miss rate of<5%was acceptable for the calcu-lating algorithm to rule out pre-ACLF.Results:In the deri-vation cohort(n=673),46 patients developed ACLF within 28 days.Serum total bilirubin,creatinine,international normalized ratio,and present proven bacterial infection at admission were associated with the development of ACLF.AD patients with≥2 organ dysfunctions had a higher risk for pre-ACLF patients[odds ratio=16.58195%confidence interval:(4.271-64.363),p<0.001].In the derivation co-hort,67.5%of patients(454/673)had≤1 organ dysfunction and two patients(0.4%)were pre-ACLF,with a miss rate of 4.3%(missed/total,2/46).In the validation cohort,65.9%of patients(914/1388)had≤1 organ dysfunction,and four(0.3%)of them were pre-ACLF,with a miss rate of 3.4%(missed/total,4/117).Conclusions:AD patients with≤1 organ dysfunction had a significantly lower risk of developing ACLF within 28 days of admission and could be safely ruled out with a pre-ACLF miss rate of<5%. | Xiaoting Tang Hai Li Guohong Deng Xin Zheng Xianbo Wang Yan Huang Yanhang Gao Zhongji Meng Zhiping Qian Feng Liu Xiaobo Lu Yu Shi Beiling Li Wenyi Gu Xiaomei Xiang Yan Xiong Yixin Hou Jun Chen Na Gao Sen Luo Liujuan Ji Jing Li Rongjiong Zheng Haotang Ren Jinjun Chen | 2023 | Journal of Clinical and Translational Hepatology2023,11,3: | 1 |

| 15 | Au23(CR)14 nanocluster restores fibril Aβ’s unfolded state with abolished cytotoxicity and dissolves endogenous Aβplaques显示文摘The misfolding of amyloid-β(Aβ)peptides from the natural unfolded state toβ-sheet structure is a critical step,leading to abnormal fibrillation and formation of endogenous Aβplaques in Alzheimer’s disease(AD).Previous studies have reported inhibition of Aβfibrillation or disassembly of exogenous Aβfibrils in vitro.However,soluble Aβoligomers have been reported with increased cytotoxicity;this might partly explain why current clinical trials targeting disassembly of Aβfibrils by anti-Aβantibodies have failed so far.Here we show that Au23(CR)14(a new Au nanocluster modified by Cys-Arg(CR)dipeptide)is able to completely dissolve exogenous mature Aβfibrils into monomers and restore the natural unfolded state of Aβpeptides from misfoldedβ-sheets.Furthermore,the cytotoxicity of Aβ40 fibrils when dissolved by Au23(CR)14 is fully abolished.More importantly,Au23(CR)14 is able to completely dissolve endogenous Aβplaques in brain slices from transgenic AD model mice.In addition,Au23(CR)14 has good biocompatibility and infiltration ability across the blood–brain barrier.Taken together,this work presents a promising therapeutics candidate for AD treatment,and manifests the potential of nanotechnological approaches in the development of nanomedicines. | Wenkang Zhang Guanbin Gao Zhongjie Ma Zhuoying Luo Meng He Taolei Sun | 2020 | National Science Review2020,7,4: | 0 |
| 16 | mTOR Signaling: The Interface Linking Cellular Metabolism and Hepatitis B Virus Replication显示文摘Mammalian target of rapamycin(m TOR) is a conserved Ser/Thr kinase that includes m TOR complex(m TORC) 1 and m TORC2. The m TOR pathway is activated in viral hepatitis, including hepatitis B virus(HBV) infection-induced hepatitis.Currently, chronic HBV infection remains one of the most serious public health issues worldwide. The unavailability of effective therapeutic strategies for HBV suggests that clarification of the pathogenesis of HBV infection is urgently required. Increasing evidence has shown that HBV infection can activate the m TOR pathway, indicating that HBV utilizes or hijacks the m TOR pathway to benefit its own replication. Therefore, the m TOR signaling pathway might be a crucial target for controlling HBV infection. Here, we summarize and discuss the latest findings from model biology research regarding the interaction between the m TOR signaling pathway and HBV replication. | Xueyu Wang Zhiqiang Wei Yongfang Jiang Zhongji Meng Mengji Lu | 2021 | Virologica Sinica2021,36,6: | 0 |
| 17 | Investigation on the short-term outcome and prognostic impact of predisposition,and precipitants in inpatients with chronic liver disease from Chinese AcuTe on CHronic LIver FailurE(CATCH-LIFE)cohorts显示文摘Aim:The study aimed to investigate the short-term outcomes of hospitalized patients with chronic liver disease(CLDs)and assess the prognostic impact of predisposition and precipitants,which currently remains unclear.Methods:The study included 3970 hospitalized patients with CLDs from two prospective longitudinal multicenter studies(NCT02457637 and NCT03641872)conducted in highly endemic hepatitis B virus(HBV)areas.Competing risk analysis was used to evaluate the effect of predispositions,including the etiology and severity of CLDs and precipitants;on sequential 28,90,and 365-day liver transplantation(LT)-free mortality.Results:Among all enrolled patients,76.8%of adverse outcomes(including death and LT)within one year occurred within 90 days.Compared with alcoholic etiology,the association of HBV etiology with poorer outcomes was remarkably on the 28th day(hazard ratio[HR],1.81;95%confidence interval[CI],1.07-3.06;p=0.026);however,and dimin-ished or became insignificant at 90 days and 365 days.Cirrhosis increased the adjusted risk for 365-day(HR,1.50;CI,1.13-1.99;p=0.004)LT-free mortality when compared with noncirrhosis.In patients with cirrhosis,prior decompensation(PD)independently increased the adjusted risk of 365-day LT-free mortality by 1.25-fold(p=0.021);however,it did not increase the risk for 90-day mortality.Neither the category nor the number of precipitants influenced the adjusted risk of 28 or 90-day LT-free mortality.Conclusions:The 90-day outcome should be considered a significant endpoint for evaluating the short-term prognosis of hospitalized patients with CLD.Predisposing factors,other than etiology,mainly affected the delayed(365-day)outcome.Timely effective therapy for CLD etiology,especially antiviral treatments for HBV,and post-discharge long-term surveillance monitoring in cirrhotic patients undergoing PD are suggested to enhance disease management and reduce mortality. | Yan Zhang Wenting Tan Xiaobo Wang Xin Zheng Yan Huang Beiling Li Zhongji Meng Yanhang Gao Zhiping Qian Feng Liu Xiaobo Lu Jia Shang Yubao Zheng Weituo Zhang Shan Yin Wenyi Gu Tongyu Wang Jianyi Wei Zixuan Shen Guohong Deng Yi Zhou Yixin Hou Qun Zhang Shue Xiong Jing Liu Liyuan Long Ruochan Chen Jinjun Chen Xiuhua Jiang Sen Luo Yuanyuan Chen Chang Jiang Jinming Zhao Liujuan Ji Xue Mei Jing Li Tao Li Rongjiong Zheng Xinyi Zhou Haotang Ren Yu Shi Hai Li for the CATCH‐LIFE Study Investigators of Chinese(Acute‐on)Chronic Liver Failure(CLIF)Consortium(Ch‐CLIFC) | 2023 | Portal Hypertension & Cirrhosis2023,2,3: | 0 |
| 18 | Facial liposuction combined with botulinum toxin type A:A technique for lower facial contouring显示文摘Background:Botulinum toxin type A injection,a noninvasive alternative method for treating masseteric hypertrophy,is inadequate for treating patients with a round lower face.This study aimed to investigate the operative technique and clinical results of liposuction followed by botulinum toxin type A injections in patients with masseteric hypertrophy and excessive subcutaneous fat.Methods:Sixty-five patients(50 women and 15 men)were treated using this technique between May 2014 and January 2019.Their mean age was 26.3 years(range,18–35 years)and the mean follow-up period was 13 months(range,8–18 months).Results:All patients achieved slimmer lower cheeks with improved jaw definitions after the procedure.Among the 65 patients,61(94%)expressed satisfaction with the results and believed that the procedure produced their desired face shape.No major complications were observed.The effect of this combination treatment remained stable for 12 months after the procedure.Conclusion:The authors believe that liposuction followed by botulinum toxin type A injections is an effective technique for the treatment of masseteric hypertrophy and excessive subcutaneous fat.It is also a relatively simple and safe treatment approach. | Chunjie Li Xiancheng Wang Ying Liang Borong Fang Xiang Xiong Wenbo Li Zhongjie Yi Xianxi Meng | 2021 | Chinese Journal Of Plastic and Reconstructive Surgery2021,3,3: | 0 |
