3Adakitic rocks and destruction of the North China Craton:Evidence from experimental petrology and geochemistry显示文摘The general temporal-spatial consistency for the formation of adakitic rocks and lithospheric thinning in northern China provide a window to examine the processes and mechanism for the destruction of the North China Craton.With experimental petrology data,this paper demonstrates that the adakitic rocks in northern China are the products of partial melting of middle-to high-potassic metabasalts at the base of the lower continent crust.Based on the TiO2 solubility model,many adakitic rocks in Dabie,Jiaodong and the northern part of the craton appear to have been saturated with TiO2.This indicates the presence of a Ti-rich accessory phase in their source regions.This phase must be rutile based on the decreasing Nb/La with increasing La/Yb in the adakitic rocks.The adakitic magmas were,thus,derived from a depth of more than 50 km,based on pressures (higher than 1.5 GPa) for the stability of rutile in a metabasalt system.Because present-day crustal thickness is generally only 35 km,we suggest that the destruction of the North China Craton may have led to at least 15 km of thinning or delamination of the crust.XIONG XiaoLin LIU XingCheng ZHU ZhiMin LI Yuan XIAO Wan Sheng SONG MaoShuang ZHANG Sheng WU JinHua 2011Science China Earth Sciences2011,54,6:34

5Wnt and BMP signaling crosstalk in regulating dental stem cells:Implications in dental tissue engineering显示文摘Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling.Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance,essential oral functions and the quality of life.Regenerative dentistry holds great promise in treating oral/dental disorders.The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells,along with the signaling mechanisms governing stem cell self-renewal and differentiation.In this review,we first summarize the biological characteristics of seven types of dental stem cells,including dental pulp stem cells,stem cells from apical papilla,stem cells from human exfoliated deciduous teeth,dental follicle precursor cells,periodontal ligament stem cells,alveolar bone-derived mesenchymal stem cells(MSCs),and MSCs from gingiva.We then focus on how these stem cells are regulated by bone morphogenetic protein(BMP)and/or Wnt signaling by examining the interplays between these pathways.Lastly,we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways.We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications.Thus,we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade.Fugui Zhang Jinlin Song Hongmei Zhang Enyi Huang Dongzhe Song Viktor Tollemar Jing Wang Jinhua Wang Maryam Mohammed Qiang Wei Jiaming Fan Junyi Liao Yulong Zou Feng Liu Xue Hu Xiangyang Qu Liqun Chen Xinyi Yu Hue H.Luu Michael J.Lee Tong-Chuan He Ping Ji 2016Genes & Diseases2016,3,4:16
6Sinomenine ester derivative inhibits glioblastoma by inducing mitochondria-dependent apoptosis and autophagy by PI3K/AKT/mTOR and AMPK/mTOR pathway显示文摘Glioblastoma multiforme(GBM)in the central nervous system is the most lethal advanced glioma and currently there is no effective treatment for it.Studies of sinomenine,an alkaloid from the Chinese medicinal plant,Sinomenium acutum,showed that it had inhibitory effects on several kinds of cancer.Here,we synthesized a sinomenine derivative,sino-wcj-33(SW33),tested it for antitumor activity on GBM and explored the underlying mechanism.SW33 significantly inhibited proliferation and colony formation of GBM and reduced migration and invasion of U87 and U251 cells.It also arrested the cell cycle at G2/M phase and induced mitochondria-dependent apoptosis.Differential gene enrichment analysis and pathway validation showed that SW33 exerted anti-GBM effects by regulating PI3 K/AKT and AMPK signaling pathways and significantly suppressed tumorigenicity with no obvious adverse effects on the body.SW33 also induced autophagy through the PI3 K/AKT/mTOR and AMPK/mTOR pathways.Thus,SW33 appears to be a promising drug for treating GBM effectively and safely.Xiangjin Zheng Wan Li Huanli Xu Jinyi Liu Liwen Ren Yihui Yang Sha Li Jinhua Wang Tengfei Ji Guanhua Du 2021Acta Pharmaceutica Sinica B2021,11,11:15
7MicroRNAs in tomato plants显示文摘MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes.In plants,miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational repression.As a model plant to study fleshy fruit ripening,miRNA studies in tomato have made great progress recently.MiRNAs were predicted to be involved in nearly all biological processes in tomato,particularly development,differentiation,and biotic and abiotic stress responses.Surprisingly,several miRNAs were verified to be involved in tomato fruit ripening and senescence.Recent studies suggest that miRNAs are related to host-virus interactions,which raises the possibility that miRNAs can be used as diagnostic markers for response to virus infection in tomato plants.In this review,we summarize our current knowledge systematically and advance future directions for miRNA research in tomato.ZUO JinHua WANG YunXiang LIU HaiPing MA YuanZheng JU Zheng ZHAI BaiQiang FU DaQi ZHU Yi LUO YunBo ZHU BenZhong 2011Science China(Life Sciences)2011,54,7:13
8Mild hypothermia combined with a scaffold of Ng Rsilenced neural stem cells/Schwann cells to treat spinal cord injury显示文摘Because the inhibition of Nogo proteins can promote neurite growth and nerve cell differentiation, a cell-scaffold complex seeded with Nogo receptor(Ng R)-silenced neural stem cells and Schwann cells may be able to improve the microenvironment for spinal cord injury repair. Previous studies have found that mild hypothermia helps to attenuate secondary damage in the spinal cord and exerts a neuroprotective effect. Here, we constructed a cell-scaffold complex consisting of a poly(D,L-lactide-co-glycolic acid)(PLGA) scaffold seeded with Ng R-silenced neural stem cells and Schwann cells, and determined the effects of mild hypothermia combined with the cell-scaffold complexes on the spinal cord hemi-transection injury in the T9 segment in rats. Compared with the PLGA group and the Ng R-silencing cells + PLGA group, hindlimb motor function and nerve electrophysiological function were clearly improved, pathological changes in the injured spinal cord were attenuated, and the number of surviving cells and nerve fibers were increased in the group treated with the Ng R-silenced cell scaffold + mild hypothermia at 34°C for 6 hours. Furthermore, fewer pathological changes to the injured spinal cord and more surviving cells and nerve fibers were found after mild hypothermia therapy than in injuries not treated with mild hypothermia. These experimental results indicate that mild hypothermia combined with Ng R gene-silenced cells in a PLGA scaffold may be an effective therapy for treating spinal cord injury.Dong Wang Jinhua Liang Jianjun Zhang Shuhong Liu Wenwen Sun 2014Neural Regeneration Research2014,9,24:12
9Virus-induced Gene Silencing in Eggplant(Solanum melongena)显示文摘Eggplant(Solanum melongena)is an economically important vegetable requiring investigation into its various genomic functions.The current limitation in the investigation of genomic function in eggplant is the lack of effective tools available for conducting functional assays.Virus-induced gene silencing(VIGS)has played a critical role in the functional genetic analyses.In this paper,TRV-mediated VIGS was successfully elicited in eggplant.We first cloned the CDS sequence of PDS(PHYTOENE DESATURASE) in eggplant and then silenced the PDS gene.Photo-bleaching was shown on the newly-developed leaves four weeks after agroinoculation,indicating that VIGS can be used to silence genes in eggplant.To further illustrate the reliability of VIGS in eggplant,we selected Chl H,Su and CLA1 as reporters to elicit VIGS using the high-pressure spray method.Suppression of Chl H and Su led to yellow leaves,while the depletion of CLA1 resulted in albino.In conclusion,four genes,PDS,Chl H,Su(Sulfur),CLA1,were down-regulated significantly by VIGS,indicating that the VIGS system can be successfully applied in eggplant and is a reliable tool for the study of gene function.Haiping Liu Daqi Fu Benzhong Zhu Huaxue Yan Xiaoying Shen Jinhua Zuo Yi Zhu Yunbo Luo 2012Journal of Integrative Plant Biology2012,54,6:11
10Shuganjieyu capsule increases neurotrophic factor expression in a rat model of depression显示文摘Shuganjieyu capsule has been approved for clinical treatment by the State Food and Drug Administration of China since 2008. In the clinic, Shuganjieyu capsule is often used to treat mild to moderate depression. In the rat model of depression established in this study, Shuganjieyu capsule was administered intragastrically daily before stress. Behavioral results confirmed that depressive symptoms lessened after treatment with high-dose(150 mg/kg) Shuganjieyu capsule. Immunohistochemistry results showed that high-dose Shuganjieyu capsule significantly increased phosphorylation levels of phosphorylation cyclic adenosine monophosphate response element binding protein and brain-derived neurotrophic factor expression in the medial prefrontal cortex and hippocampal CA3 area. Overall, our results suggest that in rats, Shuganjieyu capsule effectively reverses depressive-like behaviors by increasing expression levels of neurotrophic factors in the brain.Jinhua Fu Yingjin Zhang Renrong Wu Yingjun Zheng Xianghui Zhang Mei Yang Jingping Zhao Yong Liu 2014Neural Regeneration Research2014,9,5:10
11The efficiency and toxicity of dodecafluoro-2-methylpentan-3-one in suppressing lithium-ion battery fire显示文摘Currently,the effective and clean suppression of lithium-ion battery(LIB)fires remains a challenge.The present work investigates the use of various inhibitor doses(Xin)of dodecafluoro-2-methylpentan-3-one(C_(6) F_(12)O)in 300 Ah LIBs,and systematically examines the thermal and toxic hazards of the extinguished batteries via real scale combustion and gas analysis.The inhibitor is shown to be completely effective.The inhibition mechanism involves a combination of chemical inhibition and physical cooling.While the chemical inhibition effect tends to saturate with increasing Xin,the physical cooling remains effective at higher inhibitor doses.However,extinguishing the battery fire with a high Xin of C_(6)F_(12)O is found to incur serious toxicity problems.These results are expected to provide a guideline for the design of inhibitor doses for the suppression of LIB fires.Yujun Liu Kai Yang Mingjie Zhang Shi Li Fei Gao Qiangling Duan Jinhua Sun Qingsong Wang 2022Journal of Energy Chemistry2022,31,2:10
12Microstructure of premixed propane/air flame in the transition from laminar to turbulent combustion显示文摘In order to explore the flame structure and propagation behavior of premixed propane/air in the transi-tion from laminar to turbulent combustion, the high speed camera and Schlieren images methods were used to record the photograph of flame propagation process in a semi-vented pipe. Meanwhile, the super-thin thermocouple and ionization current probe methods were applied to detect the temperature distribution and reaction intensity of combustion reaction. The characteristics of propane/air flame propagation and microstructure were analyzed in detail by the experimental results coupled with chemical reaction thermodynamics. In the test, the particular tulip flame behavior and the formation process in the laminar-turbulent transition were disclosed clearly. From the Schlieren images and iron current results, one conclusion can be drawn that the small-scale turbulent combustion also appeared in laminar flame, which made little influence on the flame shape, but increased the flame thickness obviously.CHEN XianFeng SUN JinHua LIU Yi LIU XuanYa CHEN SiNing LU ShouXiang 2007Chinese Science Bulletin2007,52,5:9
13Curcumin protects against ischemic spinal cord injury The pathway effect显示文摘Inducible nitric oxide synthase and N-methyl-D-aspartate receptors have been shown to participate in nerve cell injury during spinal cord ischemia.This study observed a protective effect of curcumin on ischemic spinal cord injury.Models of spinal cord ischemia were established by ligating the lumbar artery from the left renal artery to the bifurcation of the abdominal aorta.At 24 hours after model establishment,the rats were intraperitoneally injected with curcumin.Reverse transcription-polymerase chain reaction and immunohistochemical results demonstrated that after spinal cord ischemia,inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression significantly increased.However,curcumin significantly decreased inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression in the ischemic spinal cord.Tarlov scale results showed that curcumin significantly improved motor function of the rat hind limb after spinal cord ischemia.The results demonstrate that curcumin exerts a neuroprotective effect against ischemic spinal cord injury by decreasing inducible nitric oxide synthase and N-methyl-D-aspartate receptor expression.Jinhua Zhang Hao Wei Meimei Lin Chunmei Chen Chunhua Wang Maobai Liu 2013Neural Regeneration Research2013,8,36:9
14Analysis of DNA methylation variation in wheat genetic background after alien chromatin introduction based on methylation-sensitive amplification polymorphism显示文摘During the process of alien germplasm introduced into wheat genome by chromosome engineering, extensive genetic variations of genome structure and gene expression in recipient could be induced. In this study, we performed GISH (genome in situ hybridization) and AFLP (amplified fragment length po-lymorphism) on wheat-rye chromosome translocation lines and their parents to detect the identity in genomic structure of different translocation lines. The results showed that the genome primary struc-ture variations were not obviously detected in different translocation lines except the same 1RS chromosome translocation. Methylation sensitive amplification polymorphism (MSAP) analyses on genomic DNA showed that the ratios of fully-methylated sites were significantly increased in translo-cation lines (CN12, 20.15%; CN17, 20.91%; CN18, 22.42%), but the ratios of hemimethylated sites were significantly lowered (CN12, 21.41%; CN17, 23.43%; CN18, 22.42%), whereas 16.37% were fully-me-thylated and 25.44% were hemimethylated in case of their wheat parent. Twenty-nine classes of me-thylation patterns were identified in a comparative assay of cytosine methylation patterns between wheat-rye translocation lines and their wheat parent, including 13 hypermethylation patterns (33.74%), 9 demethylation patterns (22.76%) and 7 uncertain patterns (4.07%). In further sequence analysis, the alterations of methylation pattern affected both repetitive DNA sequences, such as retrotransposons and tandem repetitive sequences, and low-copy DNA.ZHANG Yong LIU ZhaoHui LIU Cheng YANG ZuJun DENG KeJun PENG JinHua ZHOU JianPing LI GuangRong TANG ZongXiang REN ZhengLong 2008Chinese Science Bulletin2008,53,1:8
15Design,methodology,and baseline of whole city‑million scale children and adolescents myopia survey(CAMS)in Wenzhou,China显示文摘Background:Myopia is the most common visual impairment in children and adolescents worldwide.This study described an economical and effective population-based screening pipeline and performed the project of a million scale children and adolescents myopia survey(CAMS),which will shed light on the further study of myopia from the level of epidemiology and precision medicine.Methods:We developed a novel population-based screening pattern,an intelligent screening process and internetbased information transmission and analysis system to carry out the survey consisting of school children in Wenzhou,China.The examination items include unaided distance visual acuity,presenting distance visual acuity,and noncycloplegic autorefraction.Myopia and high myopia were defined as spherical equivalent(SE)≤−1.00 diopters(D)and SE≤−6.00 D,respectively.Next,the reports of the vision checking were automatically sent to parents and the related departments.The CAMS project will be done two to four times annually with the support of the government.An online eyesight status information management system(OESIMS)was developed to construct comprehensive and efficient electronic vision health records(EVHRs)for myopia information inquiry,risk pre-warning,and further study.Results:The CAMS completed the first-round of screening within 30 days for 99.41%of Wenzhou students from districts and counties,in June 2019.A total of 1,060,925 participants were eligible for CAMS and 1,054,251(99.37%participation rate)were selected through data quality control,which comprised 1305 schools,and 580,609,251,050 and 170,967 elementary,middle,and high school students.The mean age of participants was 12.21±3.32 years(6-20 years),the female-to-male ratio was 0.82.The prevalence of myopia in elementary,middle,and high school students was 38.16%,77.52%,and 84.00%,respectively,and the high myopia incidence was 0.95%,6.90%,and 12.98%.Conclusions:The CAMS standardized myopia screening model involves automating large-scale information collection,data transmission,data analysis and early warning,thereby supporting myopia prevention and control.The entire survey reduced 90%of staff,cost,and time consumption compared with previous surveys.This will provide new insights for decision support for public health intervention.Liangde Xu Youyuan Zhuang Guosi Zhang Yunlong Ma Jian Yuan Changseng Tu MiaoMiao Li Wencan Wang Yaru Zhang Xiaoyan Lu Jing Li Xinting Liu Zhengbo Xue Meng Zhou Jie Sun Jinhua Bao Ming Li Fan Lu Hong Wang Jianzhong Su Jia Qu 2021Eye and Vision2021,8,1:7
16Metal nanoparticles induced photocatalysis显示文摘Photocatalysis induced by light absorption of metal nanoparticles(NPs) has emerged as a promising strategy for exploiting efficient visible-light-responsive composites for solar-energy conversion. In this review, we first introduce the light absorption of metal NPs and the mechanisms proposed in metal-induced photocatalysis(MIP). Then, its applications in water splitting, artificial photosynthesis and inert molecular activation are summarized. To address the challenge of low efficiency in this field, strategies in promoting catalytic activity are reviewed, and particular attention is paid to the particle-size effect of metal. Finally, the challenges and possible development directions of MIP are briefly discussed.Lequan Liu Xinnan Zhang Lufeng Yang Liteng Ren Defa Wang Jinhua Ye 2017National Science Review2017,4,5:7
17Different quasispecies with great mutations hide in the same subgroup J field strain of avian leukosis virus显示文摘Blood samples were collected from a local strain of chickens associated with serious tumor cases in Shandong Province.The samples were inoculated into chicken embryo fibroblast and DF-1 cells for virus isolation and identification,respectively.The inoculated cells were screened for three common chicken tumor viruses.Nine strains of avian leukosis virus subgroup J(ALV-J) were identified,and were designated LY1201‐LY1209.The env gene from the LY1201 strain was amplified and cloned.All nine resultant env clones(clones 01-09) were sequenced,and the gp85 and gp37 amino acid regions were subjected to homology analysis.Clones 01 and 03 had 10 amino acid deletions in the gp85 region compared to the other seven clones,suggesting that at least two quasispecies with obvious mutations coexist in the same field strain.Among these nine clones,three had identical gp85 and gp37 sequences,and were recognized as the dominant LY1201 quasispecies.The amino acid sequence homology of gp37 and gp85 among the nine clones was 98.5%-100.0% and 96.6%-100.0% respectively,suggesting that the gp85 region of the env gene can better display the quasispecies diversity of ALV-J than gp37.MAO YaQing LI WeiHua DONG Xuan LIU JinHua ZHAO Peng 2013Science China(Life Sciences)2013,56,5:6
18Robust disturbance rejection for a fractional-order system based on equivalent-input-disturbance approach显示文摘This paper presents a disturbance rejection method that is based on the equivalent-inputdisturbance approach for uncertain fractional-order(FO) systems. An FO observer is used to reconstruct the plant states and estimate the disturbances. A disturbance estimator is incorporated in the construction of the FO control system to actively compensate for the entire disturbance. A robust stability condition for the control system and the parameters of the controller are derived using an indirect Lyapunov method.The presented method effectively rejects disturbances and handles modeling uncertainties without requiring prior knowledge of the disturbance. Comparison simulations on both numerical and practical examples demonstrate the effectiveness of the proposed method.Ruijuan LIU Jinhua SHE Min WU Fenfang ZHU Zhuoyun NIE 2018Science China(Information Sciences)2018,61,7:6
19Development of a machine learning model to predict early recurrence for hepatocellular carcinoma after curative resection显示文摘Background:Early recurrence is common for hepatocellular carcinoma(HCC)after surgical resection,being the leading cause of death.Traditionally,the COX proportional hazard(CPH)models based on linearity assumption have been used to predict early recurrence,but predictive performance is limited.Machine learning models offer a novel methodology and have several advantages over CPH models.Hence,the purpose of this study was to compare random survival forests(RSF)model with CPH models in prediction of early recurrence for HCC patients after curative resection.Methods:A total of 4,758 patients undergoing curative resection from two medical centers were included.Fifteen features including age,gender,etiology,platelet count,albumin,total bilirubin,AFP,tumor size,tumor number,microvascular invasion,macrovascular invasion,Edmondson-Steiner grade,tumor capsular,satellite nodules and liver cirrhosis were used to construct the RSF model in training cohort.Discrimination,calibration,clinical usefulness and overall performance were assessed and compared with other models.Results:Five hundred survival trees were used to generate the RFS model.The five highest Variable Importance(VIMP)were tumor size,macrovascular invasion,microvascular invasion,tumor number and AFP.In training,internal and external validation cohort,the C-index of RSF model were 0.725[standard errors(SE)=0.005],0.762(SE=0.011)and 0.747(SE=0.016),respectively;the Gönen&Heller’s K of RSF model were 0.684(SE=0.005),0.711(SE=0.008)and 0.697(SE=0.014),respectively;the time-dependent AUC(2 years)of RSF model were 0.818(SE=0.008),0.823(SE=0.014)and 0.785(SE=0.025),respectively.The RSF model outperformed early recurrence after surgery for liver tumor(ERASL)model,Korean model,American Joint Committee on Cancer tumor-node-metastasis(AJCC TNM)stage,Barcelona Clinic Liver Cancer(BCLC)stage and Chinese stage.The RSF model is capable of stratifying patients into three different risk groups(low-risk,intermediate-risk,high-risk groups)in the training and two validation cohorts(all P<0.0001).A web-based prediction tool was built to facilitate clinical application(https://recurrenceprediction.shinyapps.io/surgery_predict/).Conclusions:The RSF model is a reliable tool to predict early recurrence for patients with HCC after curative resection because it exhibited superior performance compared with other models.This novel model will be helpful to guide postoperative follow-up and adjuvant therapy.Jianxing Zeng Jinhua Zeng Kongying Lin Haitao Lin Qionglan Wu Pengfei Guo Weiping Zhou Jingfeng Liu 2022Hepatobiliary Surgery and Nutrition2022,11,2:6
20Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. 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 2019Science China(Physics,Mechanics & Astronomy)2019,62,3:6
