6Hepatic artery infusion chemotherapy using mFOLFOX versus transarterial chemoembolization for massive unresectable hepatocellular carcinoma:a prospective non.randomized study显示文摘Background: Transarterial chemoembolization(TACE) is recommended as the standard care for unresectable hepatocellular carcinoma(HCC) at Barcelona Clinic Liver Cancer(BCLC) stage A-B. However, the efficacy of TACE on large(> 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy(HAIC)might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX(mFOLFOX) regimen and those ofTACE in patients with massive unresectable HCC.Methods: A prospective, non-randomized, phase II study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen(oxaliplatin, 85 mg/m^2 intra-arterial infusion; leucovorin,400 mg/m^2 intra-arterial infusion; and fluorouracil, 400 mg/m2 bolus infusion and 2400 mg/m^2 continuous infusion)every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression(TTP), and safety were assessed.Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group(52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months(hazard radio[HR] = 2.35,95% confidence interval [CI] = 1.16-4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection(10 vs. 3,P = 0.033). The proportions of grade 3-4 adverse events(AE) and serious adverse events(SAE) were lower in the HAIC group than in the TACE group(grade 3-4 AEs: 13 vs. 27, P = 0.007;SAEs: 6 vs. 15,p = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent(10 vs. 2,P = 0.026).Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.Min-Ke He Yong Le Qi-Jiong Li Zi-Shan Yu Shao-Hua Li Wei Wei Rong-Ping Guo Ming Shi 2017Chinese Journal of Cancer2017,36,12:95

8Wnt/b-catenin signaling plays an ever-expanding role in stem cell self-renewal,tumorigenesis and cancer chemoresistance显示文摘Wnt signaling transduces evolutionarily conserved pathways which play important roles in initiating and regulating a diverse range of cellular activities,including cell proliferation,calcium homeostasis,and cell polarity.The role of Wnt signaling in controlling cell proliferation and stem cell self-renewal is primarily carried out through the canonical pathway,which is the best-characterized the multiple Wnt signaling branches.The past 10 years has seen a rapid expansion in our understanding of the complexity of this pathway,as many new components of Wnt signaling have been identified and linked to signaling regulation,stem cell functions,and adult tissue homeostasis.Additionally,a substantial body of evidence links Wnt signaling to tumorigenesis of cancer types and implicates it in the development of cancer drug resistance.Thus,a better understanding of the mechanisms by which dysregulation of Wnt signaling precedes the development and progression of human cancer may hasten the development of pathway inhibitors to augment current therapy.This review summarizes and synthesizes our current knowledge of the canonical Wnt pathway in development and disease.We begin with an overview of the components of the canonical Wnt signaling pathway and delve into the role this pathway has been shown to play in stemness,tumorigenesis,and cancer drug resistance.Ultimately,we hope to present an organized collection of evidence implicating Wnt signaling in tumorigenesis and chemoresistance to facilitate the pursuit of Wnt pathway modulators that may improve outcomes of cancers in which Wnt signaling contributes to aggressive disease and/or treatment resistance.Maryam K.Mohammed Connie Shao Jing Wang Qiang Wei Xin Wang Zachary Collier Shengli Tang Hao Liu Fugui Zhang Jiayi Huang Dan Guo Minpeng Lu Feng Liu Jianxiang Liu Chao Ma Lewis L.Shi Aravind Athiviraham Tong-Chuan He Michael J.Lee 2016Genes & Diseases2016,3,1:70
9Breast cancer incidence and mortality in women in China: temporal trends and projections to 2030显示文摘Objective:Breast cancer was the most common cancer and the fifth cause of cancer deaths among women in China in 2015.The evaluation of the long-term incidence and mortality trends and the prediction of the future burden of breast cancer could provide valuable information for developing prevention and control strategies.Methods:The burden of breast cancer in China in 2015 was estimated by using qualified data from 368 cancer registries from the National Central Cancer Registry.Incident cases and deaths in 22 cancer registries were used to assess the time trends from 2000 to 2015.A Bayesian age-period-cohort model was used to project the burden of breast cancer to 2030.Results:Approximately 303,600 new cases of breast cancer(205,100 from urban areas and 98,500 from rural areas)and 70,400 breast cancer deaths(45,100 from urban areas and 24,500 from rural areas)occurred in China in 2015.Urban regions of China had the highest incidence and mortality rates.The most common histological subtype of breast cancer was invasive ductal carcinoma,followed by invasive lobular carcinoma.The age-standardized incidence and mortality rates increased by 3.3%and 1.0%per year during 2000–2015,and were projected to increase by more than 11%until 2030.Changes in risk and demographic factors between 2015 and 2030 in cases are predicted to increase by approximately 13.3%and 22.9%,whereas deaths are predicted to increase by 13.1%and 40.9%,respectively.Conclusions:The incidence and mortality of breast cancer continue to increase in China.There are no signs that this trend will stop by 2030,particularly in rural areas.Effective breast cancer prevention strategies are therefore urgently needed in China.Shaoyuan Lei Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Hongmei Zeng Wenqiang Wei Jie He 2021Cancer Biology & Medicine2021,18,3:53
10Postconditioning of sevoflurane and propofol is associated with mitochondrial permeability transition pore显示文摘Background: Sevoflurane and propofol are effective cardioprotective anaesthetic agents, though the cardioprotection of propofol has not been shown in humans. Their roles and underlying mechanisms in anesthetic postconditioning are unclear. Mitochondrial permeability transition pore (MPTP) opening is a major cause of ischemia-reperfusion injury. Here we investigated sevoflurane- and propofol-induced postconditioning and their relationship with MPTP. Methods: Isolated perfused rat hearts were exposed to 40 min of ischemia followed by 1 h of reperfusion. During the first 15 min of reperfusion, hearts were treated with either control buffer (CTRL group) or buffer containing 20 μmol/L atractyloside (ATR group), 3% (v/v) sevoflurane (SPC group), 50 μmol/L propofol (PPC group), or the combination of atractyloside with respective anesthetics (SPC+ATR and PPC+ATR groups). Infarct size was determined by dividing the total necrotic area of the left ventricle by the total left ventricular slice area (percent necrotic area). Results: Hearts treated with sevoflurane or propofol showed significantly better recovery of coronary flow, end-diastolic pressures, left ventricular developed pressure and derivatives compared with controls. Sevoflurane resulted in more protective alteration of hemodynamics at most time point of reperfusion than propofol. These improvements were paralleled with the reduction of lactate dehydrogenase release and the decrease of infarct size (SPC vs CTRL: (17.48±2.70)% vs (48.47±6.03)%, P<0.05; PPC vs CTRL: (35.60±2.10)% vs (48.47±6.03)%, P<0.05). SPC group had less infarct size than PPC group (SPC vs PPC: (17.48±2.70)% vs (35.60±2.10)%, P<0.05). Atractyloside coadministration attenuated or completely blocked the cardioprotective effect of postconditioning of sevoflurane and propofol. Conclusion: Postconditioning of sevoflurane and propofol has cardio-protective effect against ischemia-reperfusion injury of heart, which is associated with inhibition of MPTP opening. Compared to propofol, sevoflurane provides superior protection of functional recovery and infarct size.Wei HE Feng-jiang ZHANG Shao-ping WANG Gang CHEN Cong-cong CHEN Min YAN 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,2:48

15Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47
16Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control.Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu 2021Science China(Life Sciences)2021,64,5:46
17Probiotics in Helicobacter pylori eradication therapy: A systematic review and meta-analysis显示文摘AIM: To summarize the evidence from randomized controlled trials(RCTs) regarding the effect of probiotics by using a meta-analytic approach.METHODS: In July 2013, we searched PubM ed, EMBASE, Ovid, the Cochrane Library, and three Chinese databases(Chinese Biomedical Literature Database, Chinese Medical Current Content, and Chinese Scientific Journals database) to identify relevant RCTs.We included RCTs investigating the effect of a combination of probiotics and standard therapy(probiotics group) with standard therapy alone(control group).Risk ratios(RRs) were used to measure the effect of probiotics plus standard therapy on Helicobacter pylori(H.pylori) eradication rates, adverse events, and patient compliance using a random-effect model.RESULTS: We included data on 6997 participants from 45 RCTs, the overall eradication rates of the probiotic group and the control group were 82.31% and 72.08%, respectively.We noted that the use of probiotics plus standard therapy was associated with an increased eradication rate by per-protocol set analysis(RR = 1.11; 95%CI: 1.08-1.15; P < 0.001) or intention-totreat analysis(RR = 1.13; 95%CI: 1.10-1.16; P < 0.001).Furthermore, the incidence of adverse events was 21.44% in the probiotics group and 36.27% in the control group, and it was found that the probiotics plus standard therapy significantly reduced the risk of adverse events(RR = 0.59; 95%CI: 0.48-0.71; P < 0.001), which demonstrated a favorable effect of probiotics in reducing adverse events associated with H.pylori eradication therapy.The specific reduction in adverse events ranged from 30% to 59%, and this reduction was statistically significant.Finally, probiotics plus standard therapy had little or no effect on patient compliance(RR = 0.98; 95%CI: 0.68-1.39; P = 0.889).CONCLUSION: The use of probiotics plus standard therapy was associated with an increase in the H.pylori eradication rate, and a reduction in adverse events resulting from treatment in the general population.However, this therapy did not improve patient compliance.Min-Min Zhang Wei Qian Ying-Yi Qin Jia He Yu-Hao Zhou 2015World Journal of Gastroenterology2015,21,14:41
18Inhibition on the production of collagen type Ⅰ, Ⅲ of activated hepatic stellate cells by antisense TIMP-1 recombinant plasmid显示文摘AIM: To investigate the inhibition effects on the productionof collagen type I, Ⅲ secreted by activated rat hepatic stellatecells (rHSCs) by antisense tissue inhibitors of metalloproteinase1 (TIMP-1) recombinant plasmid through elevating interstitialcollagenase activity.METHODS: rHSCs were extracted from normal rat liverby pronase and collagenase digestion and purified bycentrifugal elutriation, and were cultured on plastic dishesuntil they were activated to a myofibroblastic phenotypeafter 7-10 days. RT-Nest-PCR and gene recombinanttechniques were used to construct the rat antisense TIMP-1 recombinant plasmids which can express in eucaryoticcells. The recombinant plasmid and the pcDNA3 emptyplasmid were transfected in rHSCs by Effectene (QIAGEN)separately. Cells were selected after growing in DMEMcontaining 400 μg/ml G418 for 2-3 weeks. Expression ofexogenous gene was assessed by Northern blot, andexpression oflIMP-1 in rHSCs was determined by Northernblot and Western blot. We tested the interstitial collagenaseactivity with FITC-labled type I collagen as substrate.Ultimately, we quantified the type Ⅰ, Ⅲ collagen byWestern blot.RESULTS: The exogenous antisense TIMP-1 recombinantplasmid could be expressed in rHSCs well, which couldblock the expression of TIMP-1 greatly, the ratio of TIMP-1/GAPDH was 0.67, 2.41, and 2.97 separately at mRNAlevel (P<0.05); the ratio of TIMP-1/β-actin was 0.31, 0.98and 1.32 separately at protein level (P<0.05); It mightelevate active and latent interstitial collagenase activity,the collagenase activity was 0.3049, 0.1411 and 0.1196respectively. (P<0.05), which led to promotion thedegradation of type Ⅰ, Ⅲ collagen, the ratio of collagen I/β-actin was 0.63, 1.78 and 1.92 separately (P<0.05); andthe ratio of collagen Ⅲ/β-actin was 0.59, 1.81 and 1.98separately (P<0.05).CONCLUSION: These data shows that the antisense TIMP-1 recombinant plasmid has the inhibitory effects on theproduction of type Ⅰ, Ⅲ collagens secreted by activatedrHSCs in vitro. It could be a novel method to reverse hepaticfibrosis in the future.Wen-Bin Liu Chang-Qing Yang Wei Jiang Yi-Qing Wang Jing-Sheng Guo Bo-Ming He Ji-Yao Wang Division of Gastroenterology, Zhongshan Hospital, Fudan University, Shanghai 200032, China 2003World Journal of Gastroenterology2003,9,2:42
19Mesenchymal stem cells derived from human placenta suppress allogeneic umbilical cord blood lymphocyte proliferation显示文摘ABSTRACTHuman placenta-derived mononuclear cells (MNC) were isolated by a Percoll density gradient and cultured in mesen-chymal stem cell (MSC) maintenance medium. The homogenous layer of adherent cells exhibited a typical fibroblast-like morphology, a large expansive potential, and cell cycle characteristics including a subset of quiescent cells. In vitrodifferentiation assays showed the tripotential differentiation capacity of these cells toward adipogenic, osteogenic andchondrogenic lineages. Flow cytometry analyses and immunocytochemistry stain showed that placental MSC was ahomogeneous cell population devoid of hematopoietic cells, which uniformly expressed CD29, CD44, CD73, CD105,CD166, laminin, fibronectin and vimentin while being negative for expression of CD31, CD34, CD45 and α-smoothmuscle actin. Most importantly, immuno-phenotypic analyses demonstrated that these cells expressed class I majorhistocompatibility complex (MHC-I), but they did not express MHC-II molecules. Additionally these cells could sup-press umbilical cord blood (UCB) lymphocytes proliferation induced by cellular or nonspecific mitogenic stimuli. Thisstrongly implies that they may have potential application in allograft transplantation. Since placenta and UCB arehomogeneous, the MSC derived from human placenta can be transplanted combined with hematopoietic stem cells(HSC) from UCB to reduce the potential graft -versus-host disease (GVHD) in recipients.Chang Dong LI Wei Yuan ZHANG He Lian LI Xiao Xia JIANG Yi ZHANG Pei Hsien TANG Ning MAO 2005Cell Research2005,15,7:36
20Sevoflurane postconditioning reduces myocardial reperfusion injury in rat isolated hearts via activation of PI3K/Akt signaling and modulation of Bcl-2 family proteins显示文摘Sevoflurane postconditioning reduces myocardial infarct size.The objective of this study was to examine the role of the phosphatidylinositol-3-kinase(PI3K)/Akt pathway in anesthetic postconditioning and to determine whether PI3K/Akt signaling modulates the expression of pro-and antiapoptotic proteins in sevoflurane postconditioning.Isolated and perfused rat hearts were prepared first,and then randomly assigned to the following groups:Sham-operation(Sham),ischemia/reperfusion(Con),sevoflurane postconditioning(SPC),Sham plus 100 nmol/L wortmannin(Sham+Wort),Con+Wort,SPC+Wort,and Con+dimethylsulphoxide(DMSO).Sevoflurane postconditioning was induced by administration of sevoflurane(2.5%,v/v) for 10 min from the onset of reperfusion.Left ventricular developed pressure(LVDP),left ventricular end-diastolic pressure(LVEDP),maximum increase in rate of LVDP(+dP/dt),maximum decrease in rate of LVDP(?dP/dt),heart rate(HR),and coronary flow(CF) were measured at baseline,R30 min(30 min of reperfusion),R60 min,R90 min,and R120 min.Creatine kinase(CK) and lactate dehydrogenase(LDH) were measured after 5 min and 10 min reperfusion.Infarct size was determined by triphenyltetrazolium chloride staining at the end of reperfusion.Total Akt and phosphorylated Akt(phospho-Akt),Bax,Bcl-2,Bad,and phospho-Bad were determined by Western blot analysis.Analysis of variance(ANOVA) and Student-Newman-Keuls' test were used to investigate the significance of differences between groups.The LVDP,±dP/dt,and CF were higher and LVEDP was lower in the SPC group than in the Con group at all points of reperfusion(P<0.05).The SPC group had significantly reduced CK and LDH release and decreased infarct size compared with the Con group [(22.9±8)% vs.(42.4±9.4)%,respectively;P<0.05].The SPC group also had increased the expression of phospho-Akt,Bcl-2,and phospho-Bad,and decreased the expression of Bax.Wortmannin abolished the cardioprotection of sevoflurane postconditioning.Sevoflurane postconditioning may protect the isolated rat heart.Activation of PI3K and modulation of the expression of pro-and antiapoptotic proteins may play an important role in sevoflurane-induced myocardial protection.Li-na YU Jing YU Feng-jiang ZHANG Mei-juan YANG Ting-ting DING Jun-kuan WANG Wei HE Tao FANG Gang CHEN Min YAN 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,9:36
