| 1 | MAPK signal pathways in the regulation of cell proliferation in mammalian cells显示文摘MAPK families play an important role in complex cellular programs like proliferation, differentiation, development, transformation, and apoptosis. At least three MAPI(families have been characterized: extracellular signal-regulated kinase (ERK), Jun kinase (JNK/SAPK) and p38 MAPK. The above effects are fulfilled by regulation of cell cycle engine and other cell proliferation related proteins. In this paper we discussed their functions and cooperation with other signal pathways in regulation of cell proliferation. | WEI ZHANG, Hui Tu LIU The Key Laboratory of Cell Proliferation and Regulation Biology of Ministry of Education, College of Life Sciences, Beijing Normal University, Beijing 100875, China | 2002 | Cell Research2002，12，1： | 107 |

| 3 | Atorvastatin protects against cerebral ischemia/ reperfusion injury through anti-inflammatory and antioxidant effects显示文摘In addition to its lipid-lowering effect, atorvastatin exerts anti-inflammatory and antioxidant effects as well. In this study, we hypothesized that atorvastatin could protect against cerebral ischemia/reperfusion injury. The middle cerebral artery ischemia/reperfusion model was established, and atorvastatin, 6.5 mg/kg, was administered by gavage. We found that, after cerebral ischemia/ reperfusion injury, levels of the inflammation-related factors E-selectin and myeloperoxidase were upregulated, the oxidative stress-related marker malondialdehyde was increased, and superoxide dismutase activity was decreased in the ischemic cerebral cortex. Atorvastatin pretreatment significantly inhibited these changes. Our findings indicate that atorvastatin protects against cerebral ischemia/reperfusion injury through anti-inflammatory and antioxidant effects. | Qiuyun Tu Hui Cao Wei Zhong Binrong Ding Xiangqi Tang | 2014 | Neural Regeneration Research2014，9，3： | 29 |
| 4 | Differentiation of Human Bone Marrow Stromal Cells into Neural-Like Cells Induced by Sodium Ferulate in vitro显示文摘Human marrow stromal cells (hMSCs) are multipotential stem cells, capable of differentiating into bone, cartilage,fat and muscle. Several recent reports demonstrated that hMSCs have been also differentiated into neural cells.However, only a few reported inducers are applicable for clinical use. This work is to explore the effects of sodium ferulate (SF) on differentiation of hMSCs into neural cells in vitro. We found that hMSCs could be induced to the cells with typical neural morphology when cultured with SF. The cells express neural proteins, such as nestin,neuron-specific enolase (NSE) and glial fibrillary acidic protein (GFAP). About 30% of the hMSC-derived cells expressed nestin when cultured with SF for 3 h, but no expression was detected after 24 h. The percentages of positive cells for NSE or GFAP were about 67% and 39% separately at 6 h, and reached the plateau phage after treatment with SF for 3 days. The data suggest that SF can induce hMSCs to differentiate into neural-like cells in vitro. | Yang Wang Zhifeng Deng Xianliang Lai Wei Tu | 2005 | Cellular & Molecular Immunology2005，2，3： | 21 |
| 5 | Expression of phosphatidylinositol-3 kinase and effects of inhibitor Wortmannin on expression of tumor necrosis factor-α in severe acute pancreatitis associated with acute lung injury显示文摘BACKGROUND: Acute lung injury(ALI) is a common and serious complication of severe acute pancreatitis(SAP). The study aimed to investigate the protective effect and mechanism of phosphatidylinositol-3 kinase(PI3K) inhibitor Wortmannin in SAP associated with ALI.METHODS: Ninety rats were randomly divided into three groups: sham operation(SO) group(n=30), SAP group(n=30), and SAP+Wortmannin(SAP+W) group(n=30). SAP model was induced by retrograde injection of 4% sodium taurocholate into the biliopancreatic duct of rats. The rate of lung water content, myeloperoxidase(MPO), matrix metalloproteinase 9(MMP-9), protein kinase B(PKB), abdphosphorylation of protein kinase B(P-PKB) activity in the lung tissue were evaluated.RESULTS: In the SAP group, the p-PKB expression in the lung tissue began to rise at 3 hours after modeling, and peaked at 12 hours(P<0.05); the rate of lung water content, MPO and TNF-α activity were also gradually increased, and the degree of lung lesion gradually increased(P<0.05). In the SAP+Wortmannin group, the p-PKB expression in the lung tissue began to rise at 3 hours after modeling, and peaked at 12 hours; it was higher than that in the SO group(P<0.05), but significantly lower than that in the SAP group(P<0.05). The rest indicators in the SAP+Wortmannin group were also significantly decreased as compared with the SAP group(P<0.05).CONCLUSIONS: The expression of phosphatidylinositol-3 kinase/protein kinase B was elevated in severe pancreatitis rats with lung injury. This suggested that PI3 K signal transduction pathway is involved in the control and release of proinfl ammatory cytokines TNF-α, which may play an important role in the pathogenesis of severe acute pancreatitis associated with lung injury. This finding indicated that Wortmannin can block the PI3 K signal transduction pathway, and inhibit the release of infl ammatory factor TNF-α. | Ming Wei Yan-jie Gong Ling Tu Jia Li Ying-hong Liang Yi-hua Zhang | 2015 | World Journal of Emergency Medicine2015，6，4： | 18 |

| 7 | Evaluation of the antioxidant effects of four main theaflavin derivatives through chemiluminescence and DNA damage analyses显示文摘Theaflavins(TFs) are the dimers of a couple of epimerized catechins,which are specially formed during black tea fermentation.To explore the differences among four main TF derivatives(theaflavin(TF 1),theaflavin3-gallate(TF 2 A),theaflavin-3'-gallate(TF 2 B),and theaflavin-3,3'-digallate(TF 3)) in scavenging reactive oxygen species(ROS) in vitro,their properties of inhibiting superoxide,singlet oxygen,hydrogen peroxide,and the hydroxyl radical,and their effects on hydroxyl radical-induced DNA oxidative damage were systematically analyzed in the present study.The results show that,compared with()-epigallocatechin gallate(EGCG),TF derivatives were good antioxidants for scavenging ROS and preventing the hydroxyl radical-induced DNA damage in vitro.TF 3 was the most positive in scavenging hydrogen peroxide and hydroxyl radical,and TF 1 suppressed superoxide.Positive antioxidant capacities of TF 2 B on singlet oxygen,hydrogen peroxide,hydroxyl radical,and the hydroxyl radical-induced DNA damage in vitro were found.The differences between the antioxidant capacities of four main TF derivatives in relation to their chemical structures were also discussed.We suggest that these activity differences among TF derivatives would be beneficial to scavenge different ROS with therapeutic potential. | Yuan-yuan WU Wei LI Yi XU En-hui JIN You-ying TU | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，9： | 13 |
| 8 | Morphology of platelet Golgi apparatus and their significance after acute cerebral infarction显示文摘Blood samples were harvested from the antecubital vein of 20 fasting patients with acute cerebral infarction at 1, 7 and 15 days after onset to prepare blood platelet suspension. Fasting antecubital vein blood was collected from an additional 20 normal adults as controls. Under transmission elec-tron microscope, platelet Golgi tubules and vesicles became significantly thickened, enlarged, and irregular after acute cerebral infarction. Alpha granules in platelets significantly reduced in number, especially 1 day after cerebral infarction. Under immunoelectron microscopy, a few alpha granules aggregated around Golgi tubules and vesicles after infarction. These results suggested that platelet Golgi apparatus displayed significant morphological changes, which were possibly associated with enhanced synthetic and secretory functions of activated platelets after acute cerebral infarction. This study used Golgi apparatus blocking agent Brefeldin A to block Golgi apparatus in an aim to study the effects of Golgi apparatus on CD40L expression on the surface of activated platelets. Flow cytometry revealed that CD40L expression on activated platelet surfaces decreased significantly when Golgi apparatus was blocked, which indicated that Golgi apparatus participated in the syn-thesis and transport of CD40L to the platelet surface. | Wei Lu Dong Xu Ranran Tu Zhiping Hu | 2013 | Neural Regeneration Research2013，8，23： | 13 |
| 9 | Au-decorated porous structure graphene with enhanced sensing performance for low-concentration NO2 detection显示文摘A recent progress in new emerging two-dimensional(2 D)materials has provided promising opportunity for gas sensing in ultra-low detectable concentration.In this work,we have demonstrated a flexible NO2 gas sensor with porous structure graphene on polyethylene terephthalate substrates operating at room temperature.The gas sensor exhibited good performance with response of 1.2%and a fast response time within 30 s after exposure to50×10^-9 NO2 gas.As porous structure of graphene increased the surface area,the sensor showed high sensitivity of ppb level for NO2 detection.Au nanoparticles were decorated on the surface of the porous structure graphene skeleton,resulting in an incensement of response compared with pristine graphene.Au nanoparticles-decorated graphene exhibits not only better sensitivity(1.5-1.6 times larger than pristine graphene)for NO2 gas detection,but also fast response.The sensor was found to be robust and sensitive under the cycling bending test,which could also be ascribed to the merits of graphene.This porous structure graphene-based gas sensor is expected to enable a simple and inexpensive flexible gas sensing platform. | Yan-Yan Fan Hai-Ling Tu Yu Pang Feng Wei Hong-Bin Zhao Yi Yang Tian-Ling Ren | 2020 | Rare Metals2020，39，6： | 13 |
| 10 | Multiscale carbon foam confining single iron atoms for efficient electrocatalytic CO2 reduction to CO显示文摘Electrocatalytic CO2 reduction to CO is a sustainable process for energy conversion.However,this process is still hindered by the diffusi limited mass transfer,low electrical conductivity and catalytic activity.Therefore,new strategies for catalyst design should be adopted to solve these problems and improve the electrocatalytic performa nee for CO production.Herein,we report a multiscale carb on foam confining〔single iron atoms prepared with the assistant of S1O2 template.The pore-enriched environment at the macro-scale facilitates the diffusion of reacta nts and products.The graphe ne nano sheets at the nano-scale promote the charge tran sfer duri ng the reaction.The single iron atoms con fined in carb on matrix at the atomic-scale provide the active sites for electrocatalytic CO2 reductio n to CO.The optimized catalyst achieves a CO Faradaic efficiency of 94.9%at a moderate potential of-0.5 V vs.RHE.Furthermore,the performance can be maintained over 60 hours due to the stable single iron atoms coordi nated with four n itroge n atoms in the carb on matrix.This work provides a promising strategy to improve both the activity and stability of single atom catalysts for electrocatalytic CO2 reduction to CO. | Zheng Zhang Chao Ma Yunchuan Tu Rui Si Jie Wei Shuhong Zhang Zhen Wang Jian-Feng Li Ye Wang Dehui Deng | 2019 | Nano Research2019，12，9： | 11 |
| 11 | The chromosome-level reference genome assembly for Panax notoginseng and insights into ginsenoside biosynthesis显示文摘Panax notoginseng,a perennial herb of the genus Panax in the family Araliaceae,has played an important role in clinical treatment in China for thousands of years because of its extensive pharmacological effects.Here,we report a high-quality reference genome of P.notoginseng,with a genome size up to 2.66 Gb and a contig N50 of 1.12 Mb,produced with third-generation PacBio sequencing technology.This is the first chromosome-level genome assembly for the genus Panax.Through genome evolution analysis,we explored phylogenetic and whole-genome duplication events and examined their impact on saponin biosynthesis.We performed a detailed transcriptional analysis of P.notoginseng and explored genelevel mechanisms that regulate the formation of characteristic tubercles.Next,we studied the biosynthesis and regulation of saponins at temporal and spatial levels.We combined multi-omics data to identify genes that encode key enzymes in the P.notoginseng terpenoid biosynthetic pathway.Finally,we identified five glycosyltransferase genes whose products catalyzed the formation of different ginsenosides in P.notoginseng.The genetic information obtained in this study provides a resource for further exploration of the growth characteristics,cultivation,breeding,and saponin biosynthesis of P.notoginseng. | Zhouqian Jiang Lichan Tu Weifei Yang Yifeng Zhang Tianyuan Hu Baowei Ma Yun Lu Xiuming Cui Jie Gao Xiaoyi Wu Yuru Tong Jiawei Zhou Yadi Song Yuan Liu Nan Liu Luqi Huang Wei Gao | 2021 | Plant Communications2021，2，1： | 11 |
| 12 | Huaiqihuang Granules(槐杞黄颗粒)Reduce Proteinuria by Enhancing Nephrin Expression and Regulating Necrosis Factor κB Signaling Pathway in Adriamycin-Induced Nephropathy显示文摘Objective: To investigate the effects of Huaiqihuang Granules(槐杞黄颗粒, HQH), a mixture of Chinese herbs including Trametes robiniophila Murr, Fructus Lycii and Polygonatum sibiricum, on adriamycininduced nephropathy(ADRN) in rats and its underlying mechanisms. Methods: Rats with ADRN were divided into four groups: the sham group, the model group(distilled water), the low-dose HQH-treated(2 g/kg) group, and the high-dose HQH-treated(4 g/kg) group. Body weight and 24-h urinary protein(Upro) were checked every week. After 5-week intervention, at the end of the study, the rats were sacrificed and blood samples were collected for examination of biochemical parameters, including glomerular morphological makers, podocyte shape, cellular apoptosis, expressions of nephrin, inflammatory and apoptosis markers. Results: HQH ameliorated the rat's general status, proteinuria, renal morphological appearance and glomerulosclerosis. The decreased expression of nephrin in ADRN rats was increased by HQH, as well as the impaired podocyte foot process fusion. Cytosolic levels of p65 and inhibitor of nuclear factor κBα(IκBα) were decreased in ADRN rats, and recovered by the treatment of HQH. Consistently, the induced expression of tumor necrosis factor α(TNF-α), phosphorylated nuclear factor κB p65(p-NFκB p65) and IκBα in ADRN were markedly suppressed by HQH. In addition, induction of Bax, cleaved caspase-3 and cytochrome C in ADRN rats were suppressed by HQH, indicating the amelioration of apoptosis. Conclusion: HQH could ameliorate renal impairments in ADRN rats by increasing nephrin expression, inhibiting NF-κB signaling pathway via the down-regulation of p-NF-κB p65 and p-IκBα, and suppression of glomerular and tubular apoptosis. | LIU Hong SUN Wei GU Liu-bao TU Yue YU Bing-yin HU Hao | 2017 | Chinese Journal of Integrative Medicine2017，23，4： | 10 |
| 13 | Synergistic effects of tea polyphenols and ascorbic acid on human lung adenocarcinoma SPC-A-1 cells显示文摘Tea polyphenols have been shown to have anticancer activity in many studies.In the present study,we investigated effects of theaflavin-3-3'-digallate(TF3),one of the major theaflavin monomers in black tea,in combination with ascorbic acid(AA),a reducing agent,and(-)-epigallocatechin-3-gallate(EGCG),the main polyphenol presented in green tea,in combination with AA on cellular viability and cell cycles of the human lung adenocarcinoma SPC-A-1 cells.The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) assay showed that the 50% inhibition concentrations(IC50) of TF3,EGCG,and AA on SPC-A-1 cells were 4.78,4.90,and 30.62 μmol/L,respectively.The inhibitory rates of TF3 combined with AA(TF3+AA) and EGCG combined with AA(EGCG+AA) at a molar ratio of 1:6 on SPC-A-1 cells were 54.4% and 45.5%,respectively.Flow cytometry analysis showed that TF3+AA and EGCG+AA obviously increased the cell population in the G0/G1 phase of the SPC-A-1 cell cycle from 53.9% to 62.8% and 60.0%,respectively.TF3-treated cells exhibited 65.3% of the G0/G1 phase at the concentration of its IC50.Therefore,TF3+AA and EGCG+AA had synergistic inhibition effects on the proliferation of SPC-A-1 cells,and significantly held SPC-A-1 cells in G0/G1 phase.The results suggest that the combination of TF3 with AA or EGCG with AA enhances their anticancer activity. | Wei LI Jian-xiang WU You-ying TU | 2010 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010，11，6： | 10 |

| 19 | Outcomes in children with biliary atresia following liver transplantation显示文摘BACKGROUND: Congenital biliary atresia is a rare condition characterized by idiopathic dysgenesis of the bile ducts. If untreated, congenital biliary atresia leads to liver cirrhosis, liver failure and premature death. The present study aimed to evaluate the outcomes of orthotopic liver transplantation in children with biliary atresia. METHOD: We retrospectively analyzed 45 patients with biliary atresia who had undergone orthotopic liver transplantation from September 2006 to August 2012. RESULTS: The median age of the patients was 11.0 months (5-102). Of the 45 patients, 41 were younger than 3 years old. Their median weight was 9.0 kg (4.5-29.0), 34 of the 45 patients were less than 10 kg. Thirty-one patients had undergone Kasai portoenterostomy prior to orthotopic liver transplantation. We performed 30 living donor liver transplants and 15 split liver transplants. Six patients died during a follow-up. The median follow-up time of surviving patients was 11.4 months (1.4-73.7). The overall 1-, 2- and 3-year survival rates were 88.9%, 84.4% and 84.4%, respectively. CONCLUSION: With advances in surgical techniques and management, children with biliary atresia after liver transplantation can achieve satisfactory survival in China, although there remains a high risk of complications in the early postoperative period. | Li-Ying Sun Yun-Sheng Yang Zhi-Jun Zhu Wei Gao Lin Wei Xiao-Ye Sun Wei Qu Wei Rao Zhi-Gui Zeng Chong Dong Jin-Peng Tu Jian Wang Yi-He Liu Yuan Liu Li-Xin Yu Yu Wang Jing Li Zhong-Yang Shen | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，2： | 8 |
| 20 | Removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions显示文摘Large amounts of cyanide tailings are produced during the cyanidation process in gold extraction,which are hazardous solid wastes due to the toxic cyanide.Pyrite is one of the main minerals in cyanide tailings.The removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions was investigated in this study.It was found that the removal efficiency was positively correlated with pH from 5 to 12,but remained almost constant when pH was higher than 12.The highest cyanide removal efficiency of 91.10% was achieved by adding no less than 0.6 wt.% of H_2O_2.Cyanide removal was positively correlated with the CN^-adsorption amount between 1.06 and 8.5 mg/g,and temperature between 25 and 85°C.The removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions was due to the oxidation of pyrite.Hexacyanoferrate,thiocyanate and sulfate were generated with mole ratios of about 2.03:1.12:3.17 during the cyanide removal.?2018 The Research Center for Eco-Environmental Sciences,Chinese Academy of Sciences. | Yubo Tu Peiwei Han Lianqi Wei Xiaomeng Zhang Bo Yu Peng Qian Shufeng Ye | 2019 | Journal of Environmental Sciences2019，31，4： | 8 |
