| 1 | Micro-mechanical analysis of dynamic processes of nanomanipulation显示文摘In this study, atomic force microscope (AFM) tips are used as tools to cut and manipulate carbon nanotubes on various surfaces. The lateral forces acting on AFM tips during manipulation are also recorded and analyzed from the perspective of micro-mechanics. It is found that differences in surface conditions can lead to obvious increase in micro-friction between nanotube and substrate. And also due to rehybridization, carbon nanotubes present excellent resilience when undergoing different degrees of strain. Finally, carbon nanotubes can complexly deform from elastic stage to plastic stage before complete rupture. | HU Jie, ZHANG Yujun, LI Peng, WANG Hui, HUANG Lan & HU YuanzhongState Key Laboratory of Tribology, Tsinghua University, Beijing 100084, China Department of Physics, Tsinghua University, Beijing 100084, China College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China | 2004 | Science China(Physics,Mechanics & Astronomy)2004，47，z1： | 28 |
| 2 | Taxus chinensis ameliorates diabetic nephropathy through down-regulating TGF-β1/Smad pathway显示文摘Diabetic nephropathy(DN) is one of the common microvascular complications of diabetes mellitus. Renal fibrosis is closely related to the deterioration of renal function. The present study aimed to investigate protective effect of Taxus chinensis on high-fat diet/streptozotocin-induced DN in rats and explore the underlying mechanism of action. The rat DN model was established via feeding high fat diet for 4 weeks and subsequently injecting streptozotocin(30 mg·kg^(-1) body weight) intraperitoneally. The rats with blood glucose levels higher than 16.8 mmol·L^(-1) were selected for experiments. The DN rats were treated with Taxus chinensis orally(0.32, 0.64, and 1.28 g·kg^(-1)) once a day for 8 weeks. Taxus chinensis significantly improved the renal damage, which was indicated by the decreases in 24-h urinary albumin excretion rate, blood serum creatinine, and blood urea nitrogen. Histopathological examination confirmed the protective effect of Taxus chinensis. The thickness of glomerular basement membrane was reduced, and proliferation of mesangial cells and podocytes cells and increase in mesangial matrix were attenuated. Further experiments showed that Taxus chinensis treatment down-regulated the expression of TGF-β1 and α-SMA, inhibited phosphorylation of Smad2 and Smad3. These results demonstrated that Taxus chinensis alleviated renal injuries in DN rats, which may be associated with suppressing TGF-β1/Smad signaling pathway. | WENG Hong-Bo HAN Wen-Ke XIONG Yan-Wen JIN Zhou-Hui LAN Zhen LIU Cheng ZHANG Xue-Mei PENG Wen | 2018 | Chinese Journal of Natural Medicines2018，16，2： | 28 |
| 3 | Is total laparoscopic pancreaticoduodenectomy superior to open procedure? A meta-analysis显示文摘BACKGROUND Laparoscopy has been widely used in general surgical procedures,but total laparoscopic pancreaticoduodenectomy(TLPD)is still a complex and challenging surgery that is only performed in a small number of patients at a few large academic medical centers.Although the safety and feasibility of TLPD have been established,few studies have compared it with open pancreaticoduodenectomy(OPD)with regard to perioperative and oncological outcomes.Therefore,we carried out a meta-analysis to evaluate whether TLPD is superior to OPD.AIM To compare the treatment outcomes of TLPD and OPD in order to assess the safety and feasibility of TLPD.METHODS We conducted a systematic search of studies comparing TLPD with OPD that were published in the PubMed,EMBASE,and Cochrane Library databases through December 31,2018.The studies comparing TLPD and OPD with at least one of the outcomes we were interested in and with more than 10 cases in each group were included in this analysis.The Newcastle-Ottawa scale was used to assess the quality of the nonrandomized controlled trials and the Jadad scale was used to assess the randomized controlled trials.Intraoperative data,postoperative complications,and oncologic outcomes were evaluated.The metaanalysis was performed using Review Manager Software version 5.3.Random or fixed-effects meta-analyses were undertaken to measure the pooled estimates.RESULTS A total of 4790 articles were initially identified for our study.After screening,4762 articles were excluded and 28 studies representing 39771 patients(3543 undergoing TLPD and 36228 undergoing OPD)were eventually included.Patients who underwent TLPD had less intraoperative blood loss[weighted mean difference(WMD)=-260.08 mL,95%confidence interval(CI):(-336.02,-184.14)mL,P<0.00001],a lower blood transfusion rate[odds ratio(OR)=0.51,95%CI:0.36-0.72,P=0.0001],a lower perioperative overall morbidity(OR=0.82,95%CI:0.73-0.92,P=0.0008),a lower wound infection rate(OR=0.48,95%CI:0.34-0.67,P<0.0001),a lower pneumonia rate(OR=0.72,95%CI:0.60-0.85,P=0.0002),a shorter duration of intensive care unit(ICU)stay[WMD=-0.28 d,95%CI(-2.88,-1.29)d,P<0.00001]and a shorter length of hospital stay[WMD=-3.05 d,95%CI(-3.93,-2.17),P<0.00001],a lower rate of discharge to a new facility(OR=0.55,95%CI:0.39-0.78,P=0.0008),and a lower 30-d readmission rate(OR=0.81,95%CI:0.68-0.95,P=0.10)than those who underwent OPD.In addition,the TLPD group had a higher R0 rate(OR=1.28,95%CI:1.13-1.44,P=0.0001)and more lymph nodes harvested(WMD=1.32,95%CI:0.57-2.06,P=0.0005)than the OPD group.However,the patients who underwent TLPD experienced a significantly longer operative time(WMD=77.92 min,95%CI:40.89-114.95,P<0.0001)and had a smaller tumor size than those who underwent OPD[WMD=-0.32 cm,95%CI:(-0.58,-0.07)cm,P=0.01].There were no significant differences between the two groups in the major morbidity,postoperative pancreatic fistula,delayed gastric emptying,postpancreatectomy hemorrhage,bile leak,gastroenteric anastomosis fistula,intra-abdominal abscess,bowel obstruction,fluid collection,reoperation,ICU admission,or 30-d and 90-d mortality rates.For malignant tumors,the 1-,2-,3-,4-and 5-year overall survival rates were not significantly different between the two groups.CONCLUSION This meta-analysis indicates that TLPD is safe and feasible,and may be a desirable alternative to OPD,although a longer operative time is needed and only smaller tumors can be treated. | Hua Zhang Xiang Lan Bing Peng Bo Li | 2019 | World Journal of Gastroenterology2019，25，37： | 19 |

| 5 | Drag models for simulating gas–solid flow in the turbulent fluidization of FCC particles显示文摘This paper examines the suitability of various drag models for predicting the hydrodynamics of the turbulent fluidization of FCC particles on the Fluent V6.2 platform.The drag models included those of Syamlal–O’Brien,Gidaspow,modified Syamlal–O’Brien,and McKeen.Comparison between experimental data and simulated results showed that the Syamlal–O’Brien,Gidaspow,and modified Syamlal–O’Brien drag models highly overestimated gas–solid momentum exchange and could not predict the formation of dense phase in the fluidized bed,while the McKeen drag model could not capture the dilute charac- teristics due to underestimation of drag force.The standard Gidaspow drag model was then modified by adopting the effective particle cluster diameter to account for particle clusters,which was,however, proved inapplicable for FCC particle turbulent fluidization.A four-zone drag model(dense phase,subdense phase,sub-dilute phase and dilute phase)was finally proposed to calculate the gas–solid exchange coefficient in the turbulent fluidization of FCC particles,and was validated by satisfactory agreement between prediction and experiment. | Peng Li Xingying Lan Chunming Xu Gang Wang Chunxi Lu Jinsen Gao | 2009 | Particuology2009，7，4： | 13 |

| 8 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015，58，9： | 12 |
| 9 | TLR-mediated metabolic reprogramming in the tumor microenvironment: potential novel strategies for cancer immunotherapy显示文摘Cellular energy metabolism not only promotes tumor cell growth and metastasis but also directs immune cell survival,proliferation and the ability to perform specific and functional immune responses within the tumor microenvironment.A better understanding of the molecular regulation of metabolism in different cell components in the tumor-suppressive microenvironment is critical for the development of effective strategies for human cancer treatments.Toll-like receptors(TLRs)have recently been recognized as critical factors involved in tumor pathogenesis,regulating both tumor cells and tumor-infiltrating innate and adaptive immune cells.However,little is known about the molecular crosstalk between TLR signaling and tumor or/and immune cell metabolism,although there is abundant expression of TLRs in these cells.In this review,we explore the functional role of TLR signaling in reprogramming cell metabolism in the tumor microenvironment.In particular,we discuss how malignant tumors regulate metabolism to support their growth and survival,summarize more recently identified metabolic profiles of different immune cell subsets and TLR-mediated regulation of cellular metabolism in both tumor and immune cells,and further explore potential strategies targeting cell metabolism for TLR-based cancer therapy.An improved understanding of these issues should open new avenues for the development of novel strategies via TLR-mediated metabolic reprogramming of the tumor microenvironment for cancer immunotherapy. | Lan Huang Huaxi Xu Guangyong Peng | 2018 | Cellular & Molecular Immunology2018，15，5： | 11 |

| 11 | Full-color quantum dots active matrix display fabricated by ink-jet printing显示文摘Making full-color active matrix display based on quantum dot light emitting diodes(AM-QLEDs) via ink-jet printing is attractive in display industry due to QLEDs' wide color gamut and their potential manufacturing advantages of large screen size and low cost. The challenges for realizing AM-QLED display are how to achieve high quality films through ink-jet printing, multi-color patterning, electroluminescence(EL) color purity, and high efficiency. Herein, a 2-inch diagonal full-color AM-QLEDs display with pixel density of 120 pixels per inch(PPI) fabricated by ink-jet printing technique is presented. Driven by a metal oxide TFT(MOTFT) back-panel, the display exhibits a maximum brightness of 400 cd m.2, and a color gamut of 109%(NTSC 1931). The red, green, and blue(RGB) monochrome QLEDs passive matrix panels fabricated by ink-jet printing technique have a current efficiency(CE) of 2.5, 13.9, and 0.30 cd A.1, respectively. To the best of our knowledge, the efficiencies are the highest among passive matrix QLEDs panels made by ink-jet printing technique. The ink-jet printed QDs films show good thickness uniformity due to high viscosity and low volatility of the printable inks, and no cross-contamination between adjacent pixels resulting from the hydrophobic pixel defining layer. | Congbiao Jiang Lan Mu Jianhua Zou Zhiwei He Zhenji Zhong Lei Wang Miao Xu Jian Wang Junbiao Peng Yong Cao | 2017 | Science China Chemistry2017，60，10： | 10 |
| 12 | Inverted polymer solar cells with a solution-processed zinc oxide thin film as an electron collection layer显示文摘A solution-processed zinc oxide (ZnO) thin film as an electron collection layer for polymer solar cells (PSCs) with an inverted device structure was investigated. Power conversion efficiencies (PCEs) of PSCs made with a blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) are 3.50% and 1.21% for PSCs with and without the ZnO thin film, respectively. Light intensity dependence of the photocurrent and the capacitance-voltage measurement demonstrate that the increased PCEs are due to the restriction of the strong bimolecular recombination in the interface when a thin ZnO layer is inserted between the polymer active layer and the ITO electrode. These results demonstrate that the ZnO thin film plays an important role in the performance of PSCs with an inverted device structure. | YANG TingBin QIN DongHuan LAN LinFeng HUANG WenBo GONG Xiong PENG JunBiao CAO Yong | 2012 | Science China Chemistry2012，55，5： | 10 |
| 13 | Incidence and risk factors of tuberculosis among the elderly population in China:a prospective cohort study显示文摘Background:China is facing challenges of the shifting presentation of tuberculosis(TB)from younger to elderly due to an ageing population,longer life expectancy and reactivation disease.However,the burden of elderly TB and influence factors are not yet clear.To fill the gap,we generated a cohort study to measure the magnitude of TB incidence and associated factors among the elderly population aged 65 years and above in China.Methods:In this cohort established in 2013 through a prevalence survey conducted in selected sites,a total of 34076 elderlies without TB were enrolled into two-year follow-up.We used both active and passive case findings to find out all TB patients among them.The person-year(PY)incidence rates for both bacteriologically positive TB and active TB were calculated.Cox proportional regression model was performed to test effect of risk factors,and the population attributable fraction(PAF)of each risk factor contributing to incident TB among elderlies was calculated.Results:Over the two-year follow-up period,a total of 215 incident active TB were identified,62 of which were bacteriologically positive.The incidence rates for active TB and bacteriologically positive TB were 481.8 per 100000 PY(95%CI:417.4–546.2 per 100000 PY)and 138.9 per 100000 PY(95%CI:104.4–173.5 per 100000 PY),respectively.Incident cases detected by active case finding were significantly higher(P<0.001).Male,non-Han nationality,previously treated TB,ex/current smoker and body mass index(BMI)<18.5 presented as independent predictors for developing TB disease.For developing bacteriologically positive TB,the biggest contribution was from self-reported ex or current smoker(18.06%).And,for developing active TB,the biggest contribution was from non-Han nationality(35.40%),followed by male(26.80%)and age at 75 years and above(10.85%).Conclusions:Ageing population in China had a high TB incidence rate and risk to develop TB disease,implying that National TB Program(NTP)needs to prioritize for elderly.Active case finding should be applied capture more active TB cases among this particular population,especially for male,non-Han nationality,and those with identified risk factors. | Jun Cheng Yan-Ni Sun Can-You Zhang Yan-Ling Yu Li-Hong Tang Hong Peng Ying Peng Yu-Xia Yao Shuang-Yi Hou Jian-Wei Li Jin-Ming Zhao Lan Xia Lin Xu Yin-Yin Xia Fei Zhao Li-Xia Wang Hui Zhang | 2020 | Infectious Diseases of Poverty2020，9，1： | 10 |
| 14 | Efficacy of small-volume simethicone given at least 30 min before gastroscopy显示文摘AIM To evaluate the efficacy of 5 m L simethicone solution in decreasing gastric foam if given at least 30 min before gastroscopy.METHODS This was a randomized, placebo controlled, endoscopist blinded study performed at Changi General Hospital. Patients were at least 21 years old, had no prior sur-gical resection of the upper gastrointestinal tract, and scheduled for elective diagnostic gastroscopies. The primary outcome was the total mucosal visibility score(TMVS) which was evaluated using Mc Nally score. The sample size was calculated to be 24 per group(SD 2.4, 80% power, P < 0.05, 2-sample t test). RESULTS Fifty-four patients were randomised to receive either simethicone [1 m L liquid simethicone(100 mg) in 5 m L of water] or placebo(5 m L of water) at least 30 min before their gastroscopy. Six accredited consultants conductedthe gastroscopy, and the interobserver agreement of scoring TMVS was good with a Kappa statistic of 0.73. The simethicone group had significantly better mean TMVS compared to placebo(5.78 ± SD 1.65 vs 8.89 ± SD 1.97, P < 0.001). The improvement was statistically significant for the duodenum and the gastric antrum, angularis, body, and fundus. Percent 51.9 of patients in the simethicone group had a TMVS of 4(no bubbles at all) to 5(only 1 area with minimal bubbles), while in the placebo group 3.7% of patients had TMVS of 4 or 5. The number needed to treat was 2.1 to avoid a TMVS of 6 and more. The simethicone group also had a significantly shorter procedure time with less volume of additional flushes required during gastroscopy to clear away obscuring gastric foam.CONCLUSION With a premedication time of at least 30 min, 5 m L simethicone can significantly decrease gastric foam, decrease the volume of additional flushes, and shorten gastroscopy time. | Mingjun Song Andrew Boon Eu Kwek Ngai Moh Law Jeannie Peng Lan Ong Jessica Yi-Lyn Tan Prem Harichander Thurairajah Daphne Shih Wen Ang Tiing Leong Ang | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，4： | 10 |
| 15 | Epidemiology,clinical and laboratory characteristics of currently alive HIV-1 infected former blood donors naive to antiretroviral therapy in Anhui Province,China显示文摘Background Unregulated commercial blood/plasma collection among farmers occurred between 1992 and 1995 in central China and caused the second major epidemic of human immunodeficiency virus type 1 (HIV-1) infection in China. It is important to characterize HIV-1-infected former blood donors and to study characteristics associated with disease progression for future clinical intervention and vaccine development. Methods A cross-sectional study was performed on HIV-1-infected former blood donors (FBDs) and age-matched HIV-seronegative local residents. Demographic, epidemiologic, clinical and key laboratory data were collected from all study participants. Both unadjusted and adjusted multivariate linear regressions were employed to analyze the association of the decrease of CD4+ T-cell counts with other characteristics. Results Two hundred and ninety-four HIV-1-infected FBDs and 59 age-matched HIV-seronegative local residents were enrolled in this study. The unregulated blood/plasma collection occurred more than a decade (10.8 -12.8 years) ago, which caused the rapid spread of HIV-1 infection and the high prevalence of co-infection with hepatitis C virus (HCV, 89.5%); hepatitis B virus (HBV) co-infection was observed in only 11 HIV+participants (3.7%). Deterioration in both clinical manifestation and laboratory parameters and increase of viral loads were observed in parallel with the decrease of CD4+ T-cell counts. The decrease of total lymphocyte counts (P<0.001) and hemoglobin levels (P<0.001) and the appearance of dermatosis (P=0.03) were observed in parallel with the decrease of CD4+ T-cell counts whereas viral loads (P<0.001) and CD8+ T-cell counts (P=0.01) were inverselyassociated with CD4+ T-cell counts. Conclusions Co-infection with HCV but not HBV is highly prevalent among HIV-1-infected FBDs. CD4+ T-cell counts is a reliable indicator for disease progression among FBDs. Total lymphocyte counts, hemoglobin level and appearance of dermatosis were positively associated with CD8+ T-cell counts and viral loads were inversely associated with the decreased CD4+ T-cell counts. | XU Jian-qing WANG Jian-jun HAN Li-feng XU Chen RUAN Yu-hua XU Zhen-hou CHEN Xi LIU Zhen-dong WANG Jun SU Bing DING Xin-ping GAO Bing GU Yong-bin CAO Xiao-yun XING Hui HONG Kun-xue PENG Hong ZHAO Quan-bi YUAN Lin FENG Yi ZHANG Gui-yun MA Li-ying WU Lan SHAO Yi-ming | 2006 | Chinese Medical Journal2006，，23： | 9 |
| 16 | Transplantation of bone marrow-derived endothelial progenitor cells and hepatocyte stem cells from liver fibrosis rats ameliorates liver fibrosis显示文摘AIM To explore the effectiveness for treating liver fibrosisby combined transplantation of bone marrow-derived endothelial progenitor cells(BM-EPCs) and bone marrow-derived hepatocyte stem cells(BDHSCs) from the liver fibrosis environment.METHODS The liver fibrosis rat models were induced with carbon tetrachloride injections for 6 wk. BM-EPCs from rats with liver fibrosis were obtained by different rates of adherence and culture induction. BDHSCs from rats with liver fibrosis were isolated by magnetic bead cell sorting. Tracing analysis was conducted by labeling EPCs with PKH26 in vitro to show EPC location in the liver. Finally, BM-EPCs and/or BDHSCs transplantation into rats with liver fibrosis were performed to evaluate the effectiveness of BM-EPCs and/or BDHSCs on liver fibrosis.RESULTS Normal functional BM-EPCs from liver fibrosis rats were successfully obtained. The co-expression level of CD133 and VEGFR2 was 63.9% ± 2.15%. Transplanted BM-EPCs were located primarily in/near hepatic sinusoids. The combined transplantation of BM-EPCs and BDHSCs promoted hepatic neovascularization, liver regeneration and liver function, and decreased collagen formation and liver fibrosis degree. The VEGF levels were increased in the BM-EPCs(707.10 ± 54.32) and BM-EPCs/BDHSCs group(615.42 ± 42.96), compared with those in the model group and BDHSCs group(P < 0.05). Combination of BM-EPCs/BDHSCs transplantation induced maximal up-regulation of PCNA protein and HGF m RNA levels. The levels of alanine aminotransferase(AST), aspartate aminotransferase, total bilirubin(TBIL), prothrombin time(PT) and activated partial thromboplastin time in the BMEPCs/BDHSCs group were significantly improved, to be equivalent to normal levels(P > 0.05) compared with those in the BDHSC(AST, TBIL and PT, P < 0.05) and BM-EPCs(TBIL and PT, P < 0.05) groups. Transplantation of BM-EPCs/BDHSCs combination significantly reduced the degree of liver fibrosis(staging score of 1.75 ± 0.25 vs BDHSCs 2.88 ± 0.23 or BMEPCs 2.75 ± 0.16, P < 0.05).CONCLUSION The combined transplantation exhibited maximal therapeutic effect compared to that of transplantation of BM-EPCs or BDHSCs alone. Combined transplantation of autogenous BM-EPCs and BDHSCs may represent a promising strategy for the treatment of liver fibrosis, which would eventually prevent cirrhosis and liver cancer. | Ling Lan Ran Liu Ling-Yun Qin Peng Cheng Bo-Wei Liu Bing-Yong Zhang Song-Ze Ding Xiu-Ling Li | 2018 | World Journal of Gastroenterology2018，24，2： | 9 |
| 17 | Advances in research of the mid-deep South China Sea circulation显示文摘The South China Sea(SCS)is a large marginal sea connecting the Indian and Pacific oceans.Under the factors of monsoons,strait transport,and varied bathymetry,the SCS presents a three-layer structure and strong diapycnal mixing which is far greater than that in the open ocean.Theoretical analysis and observations reveal that internal tides,internal solitary waves,and strong winds are the sources of the strong mixing in the northern SCS.A major consequence of the strong mixing is an active mid-deep circulation system.This system promotes exchange of water between the SCS and adjacent oceans,and also regulates the upper layer of wind-driven circulation,making the 3 dimensional SCS circulation clearly different from that in other tropical and subtropical marginal seas.The mass transport capacity of the mid-deep circulation has a substantial impact on marine sedimentation,the biogeochemical cycle,and other processes in the SCS.This paper summarizes the recent advances in middeep sea circulation dynamics of the SCS,and discusses the opportunities and challenges in this area. | Dongxiao WANG Qiang WANG Shuqun CAI Xiaodong SHANG Shiqiu PENG Yeqiang SHU Jingen XIAO Xiaohui XIE Zhiwei ZHANG Zhiqiang LIU Jian LAN Dake CHEN Huijie XUE Guihua WANG Jianping GAN Xinong XIE Rui ZHANG Hui CHEN Qingxuan YANG | 2019 | Science China Earth Sciences2019，62，12： | 8 |
| 18 | Cytotoxic Effect on Osteosarcoma MG-63 Cells by Degradation of Magnesium显示文摘Biocompatible and biodegradable magnesium(Mg)based metals have attracted great interest for use in orthopedic implants and devices.Based on our previous study that Mg with and without micro-arc oxidation(MAO)coating showed obvious cytotoxic effect on tumor cells due to the increase of pH value during the degradation of Mg,this study further evaluated the cytotoxic effect of Mg and MAO coated Mg on osteosarcoma(MG-63)cells by analyzing the cell adhesion,morphology and number through observation of scanning electron microscope,as well as live/dead staining,lactate dehydrogenase(LDH)activity and 4,6-diamidino-2-phenylindole(DAPI)assay.The results indicated that,compared to titanium,Mg could strongly inhibit the cell adherence,morphology and number of MG-63 on the surface of the naked Mg,whereas the MAO coated Mg showed relative weak cytotoxic effect on MG-63 cells,expecting that magnesium based metals with suitable coating can be designed to be applied as tumor prosthesis in the clinical practice. | Mei Li Ling Ren LiHua Li Peng He GuoBo Lan Yu Zhang Ke Yang | 2014 | Journal of Materials Science & Technology2014，30，9： | 7 |
| 19 | Surface enhanced Raman spectroscopy signals of mixed pesticides and their identification显示文摘A rapid and sensitive method to identify and analyze mixed pesticides of tricyclazole,paraquat and flusilazole by surface-enhanced Raman scattering has been reported.Aqueous samples can be detected by SERS in low concentrations of 0.01 mg/L, 0.1 mg/L and 2.85 mg/L for individual tricyclazole,paraquat and flusilazole respectively.When mixing the three pesticides in the low concentrations,their characteristic peaks can still be identified from the SERS spectrum of the mixture. | Hui Rong Tang Qing Qing Li Yu Lan Ren Jin Pei Geng Peng Cao Tao Sui Xuan Wang Yi Ping Du | 2011 | Chinese Chemical Letters2011，22，12： | 7 |
| 20 | A novel thioredoxin reductase inhibitor inhibits cell growth and induces apoptosis in HL-60 and K562 cells显示文摘Human thioredoxin reductase (TrxR) system is associated with cancer cell growth and anti-apoptosis process. Effects of 1,2-bis(1,2-benzisoselenazolone-3(2H)-ketone)ethane (BBSKE),a novel TrxR inhibitor,were investigated on human leu-kemia cell lines HL-60 and K562. BBSKE treatment induced cell growth inhibition and apoptosis in both cell lines. Apoptosis induced by BBSKE is through Bcl-2/Bax and caspase-3 pathways. Ehrlich's ascites carcinoma-bearing mice were used to inves-tigate the anti-tumor effect of BBSKE in vivo. Tumor-bearing mice treated with BBSKE showed an increase of life span with a comparable effect to cyclophosphamide (CTX). These results suggest a potential usage of BBSKE as a therapeutic agent against non-solid tumors. | Zuo-fu PENG Lin-xiang LAN Fang ZHAO Jing LI Qiang TAN Han-wei YIN Hui-hui ZENG | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008，9，1： | 7 |
