| 2 | Ganoderic acid hinders renal fibrosis via suppressing the TGF- β/Smad and MAPK signaling pathways显示文摘Renal fibrosis is considered as the pathway of almost all kinds of chronic kidney diseases(CKD)to the end stage of renal diseases(ESRD).Ganoderic acid(GA)is a group of lanostane triterpenes isolated from Ganoderma lucidum,which has shown a variety of pharmacological activities.In this study we investigated whether GA exerted antirenal fibrosis effect in a unilateral ureteral obstruction(UUO)mouse model.After UUO surgery,the mice were treated with GA(3.125,12.5,and 50 mg·kg^−1·d^−1,ip)for 7 or 14 days.Then the mice were sacrificed for collecting blood and kidneys.We showed that GA treatment dose-dependently attenuated UUO-induced tubular injury and renal fibrosis;GA(50 mg·kg^−1·d^−1)significantly ameliorated renal disfunction during fibrosis progression.We further revealed that GA treatment inhibited the extracellular matrix(ECM)deposition in the kidney by suppressing the expression of fibronectin,mainly through hindering the over activation of TGF-β/Smad signaling.On the other hand,GA treatment significantly decreased the expression of mesenchymal cell markers alpha-smooth muscle actin(α-SMA)and vimentin,and upregulated E-cadherin expression in the kidney,suggesting the suppression of tubular epithelial-mesenchymal transition(EMT)partially via inhibiting both TGF-β/Smad and MAPK(ERK,JNK,p38)signaling pathways.The inhibitory effects of GA on TGF-β/Smad and MAPK signaling pathways were confirmed in TGF-β1-stimulated HK-2 cell model.GA-A,a GA monomer,was identified as a potent inhibitor on renal fibrosis in vitro.These data demonstrate that GA or GA-A might be developed as a potential therapeutic agent in the treatment of renal fibrosis. | Xiao-qiang Geng Ang Ma Jin-zhao He Liang Wang Ying-li Jia Guang-ying Shao Min Li Hong Zhou Shu-qian Lin Jian-hua Ran Bao-xue Yang | 2020 | Acta Pharmacologica Sinica2020,41,5: | 43 |
| 3 | Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot. | Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia | 2021 | Burns & Trauma2021,9,1: | 17 |
| 4 | Characterization and Source Apportionment of Volatile Organic Compounds in Urban and Suburban Tianjin, China显示文摘Tianjin is the third largest megacity and the fastest growth area in China, and consequently faces the problems of surface ozone and haze episodes. This study measures and characterizes volatile organic compounds(VOCs), which are ozone precursors, to identify their possible sources and evaluate their contribution to ozone formation in urban and suburban Tianjin,China during the Ha Chi(Haze in China) summer campaign in 2009. A total of 107 species of ambient VOCs were detected,and the average concentrations of VOCs at urban and suburban sites were 92 and 174 ppbv, respectively. Of those, 51 species of VOCs were extracted to analyze the possible VOC sources using positive matrix factorization. The identified sources of VOCs were significantly related to vehicular activities, which specifically contributed 60% to urban and 42% to suburban VOCs loadings in Tianjin. Industrial emission was the second most prominent source of ambient VOCs in both urban and suburban areas, although the contribution of industry in the suburban area(36%) was much higher than that at the urban area(16%). We conclude that controlling vehicle emissions should be a top priority for VOC reduction, and that fast industrialization and urbanization causes air pollution to be more complex due to the combined emission of VOCs from industry and daily life, especially in suburban areas. | HAN Meng LU Xueqiang ZHAO Chunsheng RAN Liang HAN Suqin | 2015 | Advances in Atmospheric Sciences2015,32,3: | 16 |

| 6 | Endothelium-specific SIRT1 overexpression inhibits hyperglycemia-induced upregulation of vascular cell senescence显示文摘The rapidly increasing prevalence of diabetes mellitus worldwide is one of the most serious and challenging health problems in the 21st century.Mammalian sirtuin 1(SIRT1) has been shown to decrease high-glucose-induced endothelial cell senescence in vitro and prevent hyperglycemia-induced vascular dysfunction.However,a role for SIRT1 in prevention of hyperglycemia-induced vascular cell senescence in vivo remains unclear.We used endothelium-specific SIRT1 transgenic(SIRT1-Tg) mice and wild-type(WT) mice to construct a 40-week streptozotocin(STZ)-induced diabetic mouse model.In this mode,42.9% of wild-type(WT) mice and 38.5% of SIRT1-Tg mice were successfully established as diabetic.Forty weeks of hyperglycemia induced significant vascular cell senescence in aortas of mice,as indicated by upregulation of expression of senescence-associated markers including p53,p21 and plasminogen activator inhibitor-1(PAI-1).However,SIRT1-Tg diabetic mice displayed dramatically decreased expression of p53,p21 and PAI-1 compared with diabetic WT mice.Moreover,manganese superoxide dismutase expression(MnSOD) was significantly downregulated in the aortas of diabetic WT mice,but was preserved in diabetic SIRT1-Tg mice.Furthermore,expression of the oxidative stress adaptor p66Shc was significantly decreased in aortas of SIRT1-Tg diabetic mice compared with WT diabetic mice.Overall,these findings suggest that SIRT1-mediated inhibition of hyperglycemia-induced vascular cell senescence is mediated at least partly through the reduction of oxidative stress. | CHEN HouZao WAN YanZhen ZHOU Shuang LU YunBiao ZHANG ZhuQin ZHANG Ran CHEN Feng HAO DeLong ZHAO Xiang GUO ZhiChen LIU DePei LIANG ChihChuan | 2012 | Science China(Life Sciences)2012,55,6: | 14 |
| 7 | Dendrobium sonia polysaccharide regulates immunity and restores the dysbiosis of the gut microbiota of the cyclophosphamide-induced immunosuppressed mice显示文摘To recognize the potential medicinal value of the Dendrobium sonia, polysaccharide(DSP) was extracted, purified, and investigated for its immunomodulatory activity. In vitro, DSP was shown to enhance the viability(MTT assay) and phagocytosis of macrophages. In cyclophosphamide-induced immunosuppressed mice, DSP increased serum levels of TNF-α, IL-6 and IFN-γ(enzyme-linked immunosorbent assay, ELISA), and ameliorated the imbalance of the community of gut microbiota as detected by 16 S ribosomal RNA gene sequencing. These results suggest that DSP might be beneficial for patients under immunosuppressed conditions. | LIU Wei YAN Ran ZHANG Liang | 2019 | Chinese Journal of Natural Medicines2019,17,8: | 13 |
| 8 | Preparation of nitric humic acid by catalytic oxidation from Guizhou coal with catalysts显示文摘Nitric humic acid was prepared by catalytic oxidation between nitric acid and Guizhou coal, with added catalysts. We investigated catalytic oxidation processes and the factors that affect the reactions. The effects of different catalysts, including NiSO 4 support on active carbon (AC-NiSO 4 ), NiSO 4 support on silicon dioxide (SiO 2 -NiSO 4 ), composites of SO 4 2à /Fe 2 O 3 , Zr-iron and vanadium-iron composite were studied. As well, we investigated nitric humic acid yields and the chemical structure of products by element analysis, FT-IR and E4/E6 (an absorbance ratio at wavelengths of 465 and 665 nm of humic acid alkaline extraction solutions). The results show that the catalytic oxidation reaction with added catalysts can increase humic acid yields by 18.7%, 16.36%, 12.94%, 5.61% and 8.59%, respectively. The highest yield of humic acid, i.e., 36.0%, was obtained with AC-NiSO 4 as the catalyst. The amounts of C and H decreased with the amount of nitrogen. The increase in the E4/E6 ratio in catalytic oxidation of (Guizhou) coal shows that small molecular weights and high yields of nitric humic acid can be obtained by catalytic oxidation reactions. | Yang Zhiyuan Gong Liang Ran Pan | 2012 | International Journal of Mining Science and Technology2012,22,1: | 9 |
| 9 | Risks faced by donors of right lobe for living donor liver transplantation显示文摘BACKGROUND:Because of the shortage of deceased donors with livers fit for transplantation,living donor liver transplantation(LDLT)is becoming an attractive alternative.Attention should be paid to the donors,especially to those of the right lobe.In this study,we evaluated the risks faced by donors of the right lobe for adult-to-adult LDLT.METHODS:The perioperative data from 105 consecutive living donors of the right lobe performed in West China Hospital from January 2002 to December 2007 were retrospectively studied.Preoperative evaluation included CT,MRCP,and intraoperative cholangiography,showing liver volume,hepatic vasculature and the biliary system.The standard liver volume(SLV)and the ratio of left lobe volume to SLV were calculated.The right lobe grafts were obtained by transecting the liver on the right side of the middle hepatic vein without inflow vascular occlusion,using an ultrasonic dissector.After operation the donors were monitored in the Intensive Care Unit for about three days.Each donor was followed up for at least 6 months.RESULTS:There was no donor mortality.Major complications occurred in 14 donors(13.3%),of whom 3 received conservative treatment,8 required invasive paracentesis,and 3 required further surgery.All donors were recovered well and resumed their previous occupations.CONCLUSIONS:Donors of the right lobe face low risks.The preoperative evaluation,especially evaluation of the volume of the remnant liver,should be exact.During the operation,the patency of the remnant hepatic vasculature and bile duct must be preserved,and the extent of injury to the remnant liver should be limited as much as possible.The detection and treatment of postoperative complications should be diligently performed. | Ran, Shun Wen, Tian-Fu Yan, Lu-Nan Li, Bo Zeng, Yong Chen, Zhe-Yu Zhang, Yu Liao, Zhi-Xue Liang, Guan-Lin Li, Guo Zhang, Xian-Hua | 2009 | Hepatobiliary & Pancreatic Diseases International2009,8,6: | 8 |
| 10 | Odontoblast β-catenin signaling regulates fenestration of mouse Hertwig's epithelial root sheath显示文摘The interaction between Hertwig's epithelial root sheath(HERS) and the adjacent mesenchyme is vitally important in mouse tooth root development. We previously generated odontoblast-specific Ctnnb1(encoding β-catenin) deletion mice, and demonstrated that odontoblast β-catenin signaling regulates odontoblast proliferation and differentiation. However, the role of odontoblast β-catenin signaling in regulation of HERS behavior has not been fully investigated. Here, using the same odontoblast-specific Ctnnb1 deletion mice, we found that ablation of β-catenin signaling in odontoblasts led to aberrant HERS formation. Mechanistically, odontoblast-specific Ctnnb1 deletion resulted in elevated bone morphogenetic protein 7(Bmp7) expression and reduced expression of noggin and follistatin, both of which encode extracellular inhibitors of BMPs. Furthermore, the levels of phosphorylated Smad1/5/8 were increased in HERS cells. In vitro tissue culture confirmed that BMP7 treatment disrupted the HERS structure. Taken together, we demonstrated that odontoblast β-catenin signaling may act through regulation of BMP signaling to maintain the integrity of HERS cells. | ZHANG Ran TENG Yan ZHU Liang LIN JingTing YANG Xiao YANG Guan LI TieJun | 2015 | Science China(Life Sciences)2015,58,9: | 8 |
| 11 | A Novel Pre-control Method of Vehicle Dynamics Stability Based on Critical Stable Velocity during Transient Steering Maneuvering显示文摘The current research of direct yaw moment control(DYC) system focus on the design of target yaw moment and the distribution of wheel brake force. The differential braking intervention can effectively improve the lateral stability of the vehicle, however, the effect of DYC can be improved a step further by applying the control of vehicle longitudinal velocity. In this paper, the relationship between the vehicle longitudinal velocity and lateral stability is studied, and the simulation results show that a decrease of 5 km/h of longitudinal velocity at a particular situation can bring 100° increasing of stable steering upper limit. A critical stable velocity considering the effect of steering and yaw rate measurement is defined to evaluate the risk of losing steer-ability or stability. A novel velocity pre-control method is proposed by using a hierarchical pre-control logic and is integrated with the traditional DYC system. The control algorithm is verified through a hardware in-the-loop simulation system. Double lane change(DLC) test results on both high friction coefficient(μ) and low μ roads show that by using the pre-control method, the steering effort in DLC test can be reduced by 38% and 51% and the peak value of brake pressure control can be reduced by 20% and 12% respectively on high μ and low μ roads, the lateral stability is also improved. This research proposes a novel DYC system with lighter control effort and better control effect. | CHEN Jie SONG Jian LI Liang RAN Xu JIA Gang WU Kaihui | 2016 | Chinese Journal of Mechanical Engineering2016,29,3: | 8 |

| 13 | Atg5 regulates late endosome and lysosome biogenesis显示文摘Autophagy is an evolutionarily conserved lysosome-based degradation process.Atg5 plays a very important role in autophagosome formation.Here we show that Atg5 is required for biogenesis of late endosomes and lysosomes in an autophagy-independent manner.In Atg5 cells,but not in other essential autophagy genes defecting cells,recycling and retrieval of late endosomal components from hybrid organelles are impaired,causing persistent hybrid organelles and defective formation of late endosomes and lysosomes.Defective retrieval of late endosomal components from hybrid organelles resulting from impaired recruitment of a component of V1-ATPase to acidic organelles blocks the pH-dependent retrieval of late endosomal components from hybrid organelles.Lowering the intracellular pH restores late endosome/lysosome biogenesis in Atg5 cells.Our data demonstrate an unexpected role of Atg5 and shed new light on late endosome and lysosome biogenesis. | PENG JunYa ZHANG Ran CUI YiTong LIU HaoDong ZHAO XiaoXin HUANG Lei HU MingXu YUAN XiaoXi MA BenYu MA XiaoWei TAKASHI Ueno MASAAKI Komatsu LIANG XingJie YU Li | 2014 | Science China(Life Sciences)2014,57,1: | 6 |
| 14 | Advances in lung cancer screening and early detection显示文摘Lung cancer is associated with a heavy cancer-related burden in terms of patients’physical and mental health worldwide.Two randomized controlled trials,the US-National Lung Screening Trial(NLST)and Nederlands-Leuvens Longkanker Screenings Onderzoek(NELSON),indicated that low-dose CT(LDCT)screening results in a statistically significant decrease in mortality in patients with lung cancer,LDCT has become the standard approach for lung cancer screening.However,many issues in lung cancer screening remain unresolved,such as the screening criteria,high false-positive rate,and radiation exposure.This review first summarizes recent studies on lung cancer screening from the US,Europe,and Asia,and discusses risk-based selection for screening and the related issues.Second,an overview of novel techniques for the differential diagnosis of pulmonary nodules,including artificial intelligence and molecular biomarker-based screening,is presented.Third,current explorations of strategies for suspected malignancy are summarized.Overall,this review aims to help clinicians understand recent progress in lung cancer screening and alleviate the burden of lung cancer. | Caichen Li Huiting Wang Yu Jiang Wenhai Fu Xiwen Liu Ran Zhong Bo Cheng Feng Zhu Yang Xiang Jianxing He Wenhua Liang | 2022 | Cancer Biology & Medicine2022,19,5: | 6 |

| 16 | Senegenin promotes in vitro proliferation of human neural progenitor cells显示文摘Senegenin,an effective component of Polygala tenuifolia root extract,promotes proliferation and differentiation of neural progenitor cells in the hippocampus.However,the effects of senegenin on mesencephalon-derived neural progenitor cells remain poorly understood.Cells from a ventral mesencephalon neural progenitor cell line(ReNcell VM) were utilized as models for pharmaceutical screening.The effects of various senegenin concentrations on cell proliferation were analyzed,demonstrating that high senegenin concentrations(5,10,50,and 100 μmo/L),particularly 50 μmol/L,significantly promoted proliferation of ReNcell VM cells.In the mitogen-activated protein kinase signal transduction pathway,senegenin significantly increased phosphorylation levels of extracellular signal-regulated kinases.Moreover,cell proliferation was suppressed by extracellular signal-regulated kinase inhibitors.Results suggested that senegenin contributed to in vitro proliferation of human neural progenitor cells by upregulating phosphorylation of extracellular signal-regulated kinase. | Shi, Fang Liang, Zhigang Guo, Zixuan Li, Ran Yu, Fen Zhang, Zhanjun Wang, Xuan Wang, Xiaomin | 2011 | Neural Regeneration Research2011,6,3: | 5 |
| 17 | LRP6 downregulation promotes cardiomyocyte proliferation and heart regeneration显示文摘The adult mammalian heart is thought to be a terminally differentiated organ given the postmitotic nature of cardiomyocytes.Consequently,the potential for cardiac repair through cardiomyocyte proliferation is extremely limited.Low-density lipoprotein receptor-related protein 6(LRP6)is a Wnt co-receptor that is required for embryonic heart development.In this study we investigated the role of LRP6 in heart repair through regulation of cardiomyocyte proliferation.Lrp6 deficiency increased cardiomyocyte cell cycle activity in neonatal,juvenile and adult mice.Cardiomyocyte-specific deletion of Lrp6 in the mouse heart induced a robust regenerative response after myocardial infarction(MI),led to reduced MI area and improvement in left ventricular systolic function.In vivo genetic lineage tracing revealed that the newly formed cardiomyocytes in Lrp6-deficient mouse hearts after MI were mainly derived from resident cardiomyocytes.Furthermore,we found that the pro-proliferative effect of Lrp6 deficiency was mediated by the ING5/P21 signaling pathway.Gene therapy using the adeno-associated virus(AAV)9 miRNAi-Lrp6 construct promoted the repair of heart injury in mice.Lrp6 deficiency also induced the proliferation of human induced pluripotent stem cell-derived cardiomyocytes(iPSC-CMs).Our study identifies LRP6 as a critical regulator of cardiomyocyte proliferation,which may lead to the development of a novel molecular strategy to promote myocardial regeneration and repair. | Yahan Wu Liping Zhou Hongyu Liu Ran Duan Huixing Zhou Fulei Zhang Xiaoyu He Dongbo Lu Ke Xiong Maolin Xiong Jinzhu Zhuang Yi Liu Li Li Dandan Liang Yi-Han Chen | 2021 | Cell Research2021,31,4: | 5 |

| 19 | Combined peripheral natural killer cell and circulating tumor cell enumeration enhance prognostic efficiency in patients with metastatic triple-negative breast cancer显示文摘Objective:Triple-negative breast cancer(TNBC)is a heterogeneous disease with poor prognosis.Circulating tumor cells(CTCs)are a promising predictor for breast cancer prognoses but their reliability regarding progression-free survival(PFS)is controversial.We aim to verify their predictive value in TNBC.Methods:In present prospective cohort study,we used the Pep@MNPs method to enumerate CTCs in baseline blood samples from 75 patients with TNBC(taken at inclusion in this study)and analyzed correlations between CTC numbers and outcomes and other clinical parameters.Results:Median PFS was 6.0(range:1.0–25.0)months for the entire cohort,in whom we found no correlations between baseline CTC status and initial tumor stage(P=0.167),tumor grade(P=0.783)or histological type(P=0.084).However,among those getting first-line treatment,baseline CTC status was positively correlated with ratio of peripheral natural killer(NK)cells(P=0.032),presence of lung metastasis(P=0.034)and number of visceral metastatic site(P=0.037).Baseline CTC status was predictive for PFS in first-line TNBC(P=0.033),but not for the cohort as a whole(P=0.118).This prognostic limitation of CTC could be ameliorated by combining CTC and NK cell enumeration(P=0.049).Conclusions:Baseline CTC status was predictive of lung metastasis,peripheral NK cell ratio and PFS in TNBC patients undergoing first-line treatment.We have developed a combined CTC-NK enumeration strategy that allows us to predict PFS in TNBC without any preconditions. | Xiaoran Liu Ran Ran Bin Shao Hope S.Rugo Yanlian Yang Zhiyuan Hu Zewen Wei Fengling Wan Weiyao Kong Guohong Song Hanfang Jiang Xu Liang Ruyan Zhang Ying Yan Guobing Xu Huiping Li | 2018 | Chinese Journal of Cancer Research2018,30,3: | 4 |
| 20 | Detection of CYP2E1,a Genetic Biomarker of Susceptibility to Benzene Metabolism Toxicity in Immortal Human Lymphocytes Derived from the Han Chinese Population显示文摘Objective Cytochrome P450 2E1 (CYP2E1) is an important metabolizing enzyme involved in oxidative stress responses to benzene,a chemical associated with bone marrow toxicity and leukemia.We aimed to identify the CYP2E1 genetic biomarkers of susceptibility to benzene toxicity in support of environmental and occupational exposure prevention,and to test whether a model using immortal human lymphocytes might be an efficient tool for detecting genetic biomarkers.Methods Immortalized human lymphocyte cell lines with independent genotypes on four CYP2E1 SNP sites were induced with 0.01% phenol,a metabolite of benzene.CYP2E1 gene function was evaluated by mRNA expression and enzyme activity.DNA damage was measured by Single‐Cell Gel Electrophoresis (SCGE).Results Among the four SNPs,cells with rs2070673TT and rs2030920CC showed higher levels of CYP2E1 transcription and enzymatic activity than the other genotypes in the same SNP site.Cells with higher gene expression genotypes also showed higher comet rates compared with lower gene expression genotypes.Conclusion These results suggest that CYP2E1 rs2070673 and rs2030920 might be the genetic biomarkers of susceptibility to benzene toxicity and that the immortalized human lymphocytes model might be an efficient tool for the detection of genetic biomarkers of susceptibility to chemicals. | ZHANG Juan YIN LiHong LIANG GeYu LIU Ran FAN KaiHong PU YuePu | 2011 | Biomedical and Environmental Sciences2011,24,3: | 4 |
