| 2 | MicroRNA changes of bone marrow-derived mesenchymal stem cells differentiated into neuronal-like cells by Schwann cell-conditioned medium显示文摘Bone marrow-derived mesenchymal stem cells differentiate into neurons under the induction of Schwann cells. However, key microRNAs and related pathways for differentiation remain unclear. This study screened and identified differentially expressed microRNAs in bone marrow- derived mesenchymal stem cells induced by Schwann cell-conditioned medium, and explored targets and related pathways involved in their differentiation into neuronal-like cells. Primary bone marrow-derived mesenchymal stem cells were isolated from femoral and tibial bones, while primary Schwann cells were isolated from bilateral saphenous nerves. Bone marrow-derived mesenchymal stem cells were cultured in unconditioned (control group) and Schwann cell-conditioned medium (bone marrow-derived mesenchymal stem cell + Schwann cell group). Neuronal differentiation of bone marrow-derived mesenchymal stem cells induced by Schwann cell-conditioned medium was observed by time-lapse imaging. Upon induction, the morphology of bone marrow-derived mesencaymal stem cells changed into a neural shape with neurites. Results of quantitative reverse transcription-polymerase chain reaction revealed that nestin mRNA expression was upregulated from 1 to 3 days and downregulated from 3 to 7 days in the bone marrow-derived mesenchymal stem cell + Schwann cell group. Compared with the control group, microtubule-associated protein 2 mRNA expression gradually increased from 1 to 7 days in the bone marrow-derived mesenchymal stem cell + Schwann cell group. After 7 days of induction, microRNA analysis iden:ified 83 significantly differentially expressed microRNAs between the two groups. Gene Ontology analysis indicated enrichment of microRNA target genes for neuronal projection development, regulation of axonogenesis, and positive regulation of cell proliferation. Kyoto Encyclopedia of Genes and Genomes pathway analysis demonstrated that Hippo, Wnt, transforming growth factor-beta, and Hedgehog signaling pathv/ays were potentially associated with neural differentiation of bone marrow-derived mesenchymal stem cells. This study, which carried out successful microRNA analysis of neuronal-like cells differentiated from bone marrow-derived mesenchymal stem cells by Schwann cell induction, revealed key microRNAs and pathways involved in neural differentiation of bone marrow-derived mesenchymal stem cells. All protocols were approved by the Animal Ethics Committee of Institute of Radiation Medicine, Chinese Academy of Medical Sciences on March 12, 2017 (approval number: DWLI-20170311). | Zhi-Jian Wei Bao-You Fan Yang Liu Han Ding Hao-Shuai Tang Da-Yu Pan Jia-Xiao Shi Peng-Yuan Zheng Hong-Yu Shi Heng Wu Ang Li Shi-Qing Feng | 2019 | Neural Regeneration Research2019，14，8： | 13 |
| 3 | Circulating miR-125a but not miR-125b is decreased in active disease status and negatively correlates with disease severity as well as inflammatory cytokines in patients with Crohn's disease显示文摘AIM To determine the association of circulating mi R-125 a/b expression with the risk and disease severity of Crohn's disease(CD), and with inflammatory cytokines.METHODS Plasma samples were collected from patients with active CD(A-CD), or CD in remission(R-CD) and from healthy controls(HCs). The levels of the inflammatory cytokines interleukin-17(IL-17), tumour necrosis factor-α(TNF-α), and interferon-γ(IFN-γ) were measured by enzyme-linked immunosorbent assay. The expression of mi R-125 a/b was assessed by quantitative polymerase chain reaction(q PCR).RESULTS Twenty-nine A-CD patients, 37 R-CD patients, and 37 HCs were included in the study. Plasma mi R-125 a expression was decreased in A-CD patients comparedwith that in R-CD patients(P < 0.001) and HCs(P < 0.001). mi R-125 a expression levels enabled the differentiation of A-CD from R-CD patients [area under curve(AUC) = 0.854] and from HCs(AUC = 0.780), whereas mi R-125 b expression did not. mi R-125 a was negatively correlated with C-reaction protein(CRP)(P = 0.017), erythrocyte sedimentation rate(ESR)(P = 0.026), Crohn's disease activity index(CDAI)(P = 0.003), IL-17(P = 0.015), and TNF-α(P = 0.004) in A-CD patients. Furthermore, mi R-125 a was negatively associated with CRP(P = 0.038) and CDAI(P = 0.021) in R-CD patients. Regarding mi R-125 b, no association with CRP, CDAI, IL-17, TNF-α, or IFN-γ was found in A-CD or in R-CD patients. mi R-125 a levels gradually increased in A-CD patients who achieved clinical remission(P = 0.009) after 3-mo treatment, whereas they remained unchanged among patients who failed to achieve remission. No changes in mi R-125 b expression were detected in remission or non-remission patients after treatment. CONCLUSION Circulating mi R-125 a but not mi R-125 b is decreased in patients with active disease status and negatively correlates with disease severity and inflammatory cytokines in patients with CD. | Chen-Ming Sun Jie Wu Heng Zhang Gan Shi Zhi-Tao Chen | 2017 | World Journal of Gastroenterology2017，23，44： | 12 |
| 4 | Correlation between adult pyrethroid resistance and knockdown resistance(kdr)mutations in Aedes albopictus(Diptera:Culicidae)field populations in China显示文摘Background:Arboviral disease transmitted by Aedes albopictus such as dengue fever is an important threat to human health.Pyrethroid resistance raises a great challenge for mosquito control.A systematic assessment of Ae.albopictus resistance status in China is urgently needed,and the study of correlation between pyrethroid resistance and knockdown resistance(kdr)mutations would provide information to guide the control of the Ae.albopictus vector.Methods:Five field populations of Ae.albopictus were collected from Jinan(JN),Hangzhou(HZ),Baoshan(BS),Yangpu(YP)and Haikou(HK),China in 2017.Insecticide-impregnated papers were prepared with four pyrethroid chemicals,deltamethrin,permethrin,beta-cypermethrin and lambda-cyhalothrin.The susceptibility of Ae.albopictus to pyrethroids was tested by the WHO tube assay.Kdr mutations were identified by PCR and sequencing.Moreover,the correlation analysis between kdr alleles and pyrethroid resistance was performed.Results:All five populations of Ae.albopictus showed resistance to four pyrethroid insecticides.One kdr mutant allele at codon 1532 and three at 1534 were detected with frequency of 5.33%(I1532T),44.20%(F1534S),1.83%(F1534 L)and 0.87%(F1534C),respectively.Both 1532 and 1534 mutation mosquitoes were found in the BS and YP populations.Allele I1532T was negatively correlated with deltamethrin resistance phenotype(OR<1),while F1534S mutation was positively correlated with deltamethrin and permethrin resistance(OR>1).Conclusions:The five field populations of Ae.albopictus adults were all resistant to deltamethrin,permethrin,betacypermethrin and lambda-cyhalothrin.Mutant F1534S was clearly associated with pyrethroid resistance phenotype in Ae.albopictus and this could be developed as a molecular marker to monitor the pyrethroid resistance problem in China. | Jing-Peng Gao Han-Ming Chen Hua Shi Heng Peng Ya-Jun Ma | 2018 | Infectious Diseases of Poverty2018，7，1： | 11 |
| 5 | Characterization of cancer stem-like cells in the side population cells of human gastric cancer cell line MKN-45显示文摘Objective:Side population(SP) cells may play a crucial role in tumorigenesis and the recurrence of cancer.Many kinds of cell lines and tissues have demonstrated the presence of SP cells,including several gastric cancer cell lines.This study is aimed to identify the cancer stem-like cells in the SP of gastric cancer cell line MKN-45.Methods:We used fluorescence activated cell sorting(FACS) to sort SP cells in the human gastric carcinoma cell line MKN-45(cells labeled with Hoechst 33342) and then characterized the cancer stem-like properties of SP cells.Results:This study found that the SP cells had higher clone formation efficiency than major population(MP) cells.Five stemness-related gene expression profiles,including OCT-4,SOX-2,NANOG,CD44,and adenosine triphosphate(ATP)-binding cassette transporters gene ABCG2,were tested in SP and MP cells using quantitative real-time reverse transcription polymerase chain reaction(RT-PCR).Western blot was used to show the difference of protein expression between SP and MP cells.Both results show that there was significantly higher protein expression in SP cells than in MP cells.When inoculated into non-obese diabetic/severe combined immunodeficiency(NOD/SCID) mice,SP cells show higher tumorigenesis tendency than MP cells.Conclusions:These results indicate that SP cells possess cancer stem cell properties and prove that SP cells from MKN-45 are gastric cancer stem-like cells. | Hai-hong ZHANG Ai-zhen CA Xue-ming WEI Li DING Feng-zhi LI Ai-ming ZHENG Da-jiang DAI Rong-rong HUANG Hou-jun CAO Hai-yang ZHOU Jian-mei WANG Xue-jing WANG Wei SHI Heng ZHU Xiao-ying YUAN Lin CHEN | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，3： | 9 |

| 8 | Passive leg raising as an indicator of fluid responsiveness in patients with severe sepsis显示文摘BACKGROUND:In the management of critically ill patients,the assessment of volume responsiveness and the decision to administer a fluid bolus constitute a common dilemma for physicians.Static indices of cardiac preload are poor predictors of volume responsiveness.Passive leg raising(PLR) mimics an endogenous volume expansion(VE) that can be used to predict fluid responsiveness.This study was to assess the changes in stroke volume index(SVI) induced by PLR as an indicator of fluid responsiveness in mechanically ventilated patients with severe sepsis.METHODS:This was a prospective study.Thirty-two mechanically ventilated patients with severe sepsis were admitted for VE in ICU of the First Affiliated Hospital,Zhejiang University School of Medicine and Ningbo Medical Treatment Center Lihuili Hospital from May 2010 to December 2011.Patients with non-sinus rhythm or arrhythmia,parturients,and amputation of the lower limbs were excluded.Measurements of SVI were obtained in a semi-recumbent position(baseline) and during PLR by the technique of pulse indicator continuous cardiac output(PiCCO) system prior to VE.Measurements were repeated after VE(500 mL 6%hydroxyethyl starch infusion within 30 minutes)to classify patients as either volume responders or non-responders based on their changes in stroke volume index(ASVI) over 15%.Heart rate(HR),systolic artery blood pressure(ABPs),diastolic artery blood pressure(ABPd),mean arterial blood pressure(ABPm),mean central venous pressure(CVPm)and cardiac index(CI) were compared between the two groups.The changes of ABPs,ABPm,CVPm,and SVI after PLR and VE were compared with the indices at the baseline.The ROC curve was drawn to evaluate the value of ASVI and the change of CVPm(ACVPm) in predicting volume responsiveness.SPSS 17.0 software was used for statistical analysis.RESULTS:Among the 32 patients,22 were responders and 10 were non-responders.After PLR among the responders,some hemodynamic variables(including ABPs,ABPd,ABPm and CVPm)were significantly elevated(101.2±17.6 vs.118.6±23.7,P=0.03;52.8±10.7 vs.64.8±10.7,P=0.006;68.3+11.7 vs.81.9±14.4,P=0.008;6.8±3.2 vs.11.9±4.0,P=0.001).After PLR,the area under curve(AUC) and the ROC curve of △SV1 and ACVPm for predicting the responsiveness after VE were0.882±0.061(95%CI 0.759-1.000) and 0.805±0.079(95%CI 0.650-0.959) when the cut-off levels of ASVI and ACVPm were 8.8%and 12.7%,the sensitivities were 72.7%and 72.7%,and the specificities were 80%and 80%.CONCLUSION:Changes in ASVI and ACVPm induced by PLR are accurate indices for predicting fluid responsiveness in mechanically ventilated patients with severe sepsis. | Zhou-zhou Dong Qiang Fang Xia Zheng Heng Shi | 2012 | World Journal of Emergency Medicine2012，3，3： | 9 |

| 11 | Influence of filler-bitumen ratio on performance of modified asphalt mortar by additive显示文摘When the filler-bitumen ratio of asphalt mortar changes, its adhesion and viscoelasticity will also change, as well as its performance at the high and low temperatures, fatigue durability, and ductility. Thus, the appropriate filler- bitumen ratio directly affects the asphalt mortar's performance. This paper tested the physical indexes of the No. 70 matrix asphalt mortar modified by additive Sasobit (SB) and Sasowam (SW) through dynamic shear rheometer and bending beam rheometer under different temperature conditions, and comprehensively analyzed the high-temperature anti-rutting and fatigue performance, low-temperature crack resistance performance, and ductility of asphalt mortar. The results show that ore powder not only can increase the antirutting factor but also can increase the aging resistance of asphalt. SB has better performances than SW at high temperatures. As for the filler-bitumen ratio of asphalt mortar with additive SB, the recommended value is between 0.8 and 1.2, and the value may be a little larger for that with SW. | Hongsheng Qiu Ximing Tan Shu Shi Heng Zhang | 2013 | Journal of Modern Transportation2013，21，1： | 7 |

| 13 | Super-resolution fluorescence-assisted diffraction computational tomography reveals the threedimensional landscape of the cellular organelle interactome显示文摘The emergence of super-resolution(SR)fluorescence microscopy has rejuvenated the search for new cellular substructures.However,SR fluorescence microscopy achieves high contrast at the expense of a holistic view of the interacting partners and surrounding environment.Thus,we developed SR fluorescence-assisted diffraction computational tomography(SR-FACT),which combines label-free three-dimensional optical diffraction tomography(ODT)with two-dimensional fluorescence Hessian structured illumination microscopy.The ODT module is capable of resolving the mitochondria,lipid droplets,the nuclear membrane,chromosomes,the tubular endoplasmic reticulum,and lysosomes.Using dual-mode correlated live-cell imaging for a prolonged period of time,we observed novel subcellular structures named dark-vacuole bodies,the majority of which originate from densely populated perinuclear regions,and intensively interact with organelles such as the mitochondria and the nuclear membrane before ultimately collapsing into the plasma membrane.This work demonstrates the unique capabilities of SR-FACT,which suggests its wide applicability in cell biology in general. | Dashan Dong Xiaoshuai Huang Liuju Li Heng Mao Yanquan Mo Guangyi Zhang Zhe Zhang Jiayu Shen Wei Liu Zeming Wu Guanghui Liu Yanmei Liu Hong Yang Qihuang Gong Kebin Shi Liangyi Chen | 2020 | Light(Science & Applications)2020，9，1： | 7 |

In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 6 |

| 20 | Heteroplasmy Level of the Mitochondrial tRNA^(Leu(UUR)) A3243G Mutation in a Chinese Family Is Positively Associated with Earlier Age-of-onset and Increasing Severity of Diabetes显示文摘Objective To investigate the mutations of mitochondrial genome in a pedigree with suspected maternally inherited diabetes and deafness and to explore the correlations between the mutations and clinical features. Methods Genomic DNA was isolated from blood leucocytes of each member of the pedigree. The mitochondrial genome was amplified with 24-pair primers that could cover the entire mitochondrial DNA. Direct sequencing of PCR products was used to identify any mitochondrial DNA mutations. Results Family members on the maternal side all harbored the tRNA^(Leu(UUR)) A3243G mutation. The paternal side family members did not have the mutation. The age-of-onset of diabetes of the 4 maternal side family members was 15, 41, 44, and 65 years old, and their corresponding heteroplasmy level of the mutation was 34.5%, 14.9%, 14.6%, and 5.9%, respectively. The age-of-onset of diabetes and heteroplasmy level of A3243G mutation were negatively correlated with a correlation coefficient of -0.980 (P=0.02). Meanwhile, patient with high heteroplasmy level of A3243G mutation had relatively low severity of disease. Moreover, 6 reported polymorphisms and 2 new variants were found. Conclusions The main cause of diabetes in this pedigree is the tRNA^(Leu(UUR)) A3243G mutation. However, other gene variants may contribute to its pathogenicity. The heteroplasmy level of the tRNA^(Leu(UUR)) A3243G mutation is positively associated with earlier age-of-onset and increasing severity of diabetes. | Shi Zhang An-li Tong Yun Zhang Min Nie Yu-xiu Li Heng Wang | 2009 | Chinese Medical Sciences Journal2009，24，1： | 5 |
