| 1 | Permeability analysis of fractured vuggy porous media based on homogenization theory显示文摘Based on the characteristics of fractured vuggy porous media,a novel mathematical model was proposed to model fluid flow in such media on fine scale,i.e.,the discrete fracture-vug network model.The new model consists of three systems:porous rock system,fracture system,and vug system.The fractures and vugs are embedded in porous rock,and the isolated vugs could be connected via the discrete fracture network.The flow in porous rock and fractures follows Darcy's law,and the vugs system is free fluid region.Using a two-scale homogenization limit theory,we obtained a macroscopic Darcy's law governing the media on coarse scale.The theoretical formula of the equivalent permeability of the fractured vuggy porous media was derived.The model and method of this paper were verified by some numerical examples.At the end the permeability of some fractured vuggy porous media with typical fracture-vug structures was analyzed. | HUANG ZhaoQin,YAO Jun,LI YaJun,WANG ChenChen&LüXinRui College of Petroleum Engineering,China University of Petroleum,Qingdao 266555,China | 2010 | Science China(Technological Sciences)2010，53，3： | 22 |

| 3 | Synthesis, structure and photocatalysis properties of two 3D Isostructural Ln (Ⅲ)-MOFs based 2,6-Pyridinedicarboxylic acid显示文摘Two new 3 D metal-organic frameworks(MOFs) named [Pr_2(PDA)3-3 H_2 O]-H_2 O(1) and[Nd_2(PDA)3-3 H_2 O] H_2 O(_2) [2,6-Pyridinedicarboxylic acid(H2 PDA)] were synthesized by solvothermal method. They were characterized by elemental analyses(EA), infrared spectroscopy(FT-IR), thermogravimetric analysis(TG), photocatalysis performance and single crystal X-ray diffraction studies(XRD).The XRD analysis indicated that MOFs(1) and(2) both belong to the monoclinic system with space group P2(1)/C. The structural model were drawn by the diamond software, and the structure revel that MOFs(1) and(2) adopt three-dimensional(3 D) frameworks constructed by cross-linking of one-dimensional(1 D) infinite chain secondary building unit(SBU) by 2,6-Pyridinedicarboxylic acid and hydrogen bond as linker. These frameworks feature channels inside which coordinated H_20 solvent molecules are located. Thermogravimetric analysis showed that both MOFs are thermally stable, the photocatalytic evaluation showed the materials have a good prospect in degration methylene blue. As for complex1, the decomposition efficiency of Methylene blue was about 91.08% after 130 min and the complex 2 reach 90.45% after 160 min under the sun light. | Chenchen Zhang Siyue Wei Lixian Sun Fen Xu Pengru Huang Hongliang Peng | 2018 | Journal of Materials Science & Technology2018，34，9： | 5 |
| 4 | PI3K/Akt/mTOR signaling orchestrates the phenotypic transition and chemo-resistance of small cell lung cancer显示文摘Small cell lung cancer(SCLC)is a phenotypically heterogeneous disease with an extremely poor prognosis,which is mainly attributed to the rapid development of resistance to chemotherapy.However,the relation between the growth phenotypes and chemo-resistance of SCLC remains largely unclear.Through comprehensive bioinformatic analyses,we found that the heterogeneity of SCLC phenotype was significantly associated with different sensitivity to chemotherapy.Adherent or semiadherent SCLC cells were enriched with activation of the PI3K/Akt/mTOR pathway and were highly chemoresistant.Mechanistically,activation of the PI3K/Akt/mTOR pathway promotes the phenotypic transition from suspension to adhesion growth pattern and confers SCLC cells with chemo-resistance.Such chemo-resistance could be largely overcome by combining chemotherapy with PI3K/Akt/mTOR pathway inhibitors.Our findings support that the PI3K/Akt/mTOR pathway plays an important role in SCLC phenotype transition and chemo-resistance,which holds important clinical implications for improving SCLC treatment. | Xuefeng Li Cheng Li Chenchen Guo Qiqi Zhao Jiayu Cao Hsin-Yi Huang Meiting Yue Yun Xue Yujuan Jin Liang Hu Hongbin Ji | 2021 | Journal of Genetics and Genomics2021，48，7： | 5 |
| 5 | Parathyroid hormone increases alveolar bone homoeostasis during orthodontic tooth movement in rats with periodontitis via crosstalk between STAT3 and β-catenin显示文摘Periodontitis patients are at risk of alveolar bone loss during orthodontic treatment.The aim of this study was to investigate whether intermittent parathyroid hormone(1–34)treatment(iPTH)could reduce alveolar bone loss during orthodontic tooth movement(OTM)in individuals with periodontitis and the underlying mechanism.A rat model of OTM in the context of periodontitis was established and alveolar bone loss was observed.The control,iPTH and iPTH+stattic groups received injections of vehicle,PTH and vehicle,or PTH and the signal transducer and activator of transcription 3(STAT3)inhibitor stattic,respectively.iPTH prevented alveolar bone loss by enhancing osteogenesis and suppressing bone resorption in the alveolar bone during OTM in rats with periodontitis.This effect of iPTH was along with STAT3 activation and reduced by a local injection of stattic.iPTH promoted osteoblastic differentiation and might further regulate the Wnt/β-catenin pathway in a STAT3-dependent manner.The findings of this study suggest that iPTH might reduce alveolar bone loss during OTM in rats with periodontitis through STAT3/β-catenin crosstalk. | Cheng Zhang Tiancheng Li Chenchen Zhou Li Huang Yuyu Li Han Wang Peipei Duan Shujuan Zou Li Mei | 2020 | International Journal of Oral Science2020，12，4： | 4 |
| 6 | Amplification and expression of c-MET correlate with poor prognosis of patients with gastric cancer and upregulate the expression of PDL1显示文摘The prognostic significance of c-MET in gastric cancer(GC)remains uncertain.In the present study,we examined the amplification,expression,and the prognostic value of c-MET,human epidermal growth factor receptor 2(HER2),and programmed cell death 1 ligand 1(PDL1),together with the correlations among them in a large cohort of Chinese samples.A total of 444 patients were included.The immunohistochemistry(IHC)and the dual-color silver in situ hybridization(SISH)were performed to examine their expression and amplification.Univariate and multivariate analyses were performed by the Cox proportional hazard regression model,and survival curves were estimated by the Kaplan-Meier method.The positivity determined by IHC of c-MET was 24.8%,and the MET amplification rate was 2.3%.The positivity rates of HER2 and PDL1 were 8%and 34.7%,respectively.PDL1 expression had a significantly positive association with c-MET expression.c-MET positivity played a significant prognostic role in disease-free survival(DFS)(P=0.032).Patients with mesenchymal-epithelial transition(MET)amplification had significantly poorer prognosis on both DFS and overall survival(OS).Subgroup analysis showed that in HER2-negative patients,but not in HER2-positive patients,MET-positive patients had significantly worse DFS(P=0.000)and OS(P=0.006).c-MET regulated the expression of PDL1 through an AKT-dependent pathway.c-MET inhibitor enhanced the T-cell killing ability and increased the efficacy of PD1 antibody.c-MET was found to be an independent prognostic factor for DFS of GC patients.A combination of c-MET inhibitors and PD1 antibodies could enhance the killing capacity of T cells,providing a preliminary basis for the clinical research on the same combination in GC treatment. | Ya’nan Yang Chenchen Wang Congqi Dai Xinyang Liu Wenhua Li Mingzhu Huang Xiaoying Zhao Dongmei Ji Jin Li Weijian Guo | 2021 | Acta Biochimica et Biophysica Sinica2021，53，5： | 2 |
| 7 | Numerical Calculation of Equivalent Permeability Tensor for Fractured Vuggy Porous Media Based on Homogenization Theory显示文摘A numerical procedure for the evaluation of equivalent permeability tensor for fractured vuggy porous media is presented.At first we proposed a new conceptual model,i.e.,discrete fracture-vug network model,to model the realistic fluid flow in fractured vuggy porous medium on fine scale.This new model consists of three systems:rock matrix system,fractures system,and vugs system.The fractures and vugs are embedded in porous rock,and the isolated vugs could be connected via discrete fracture network.The flow in porous rock and fractures follows Darcy’s law,and the vugs system is free fluid region.Based on two-scale homogenization theory,we obtained an equivalent macroscopic Darcy’s law on coarse scale from fine-scale discrete fracture-vug network model.A finite element numerical formulation for homogenization equations is developed.The method is verified through application to a periodic model problem and then is applied to the calculation of equivalent permeability tensor of porous media with complex fracture-vug networks.The applicability and validity of the method for these more general fractured vuggy systems are assessed through a simple test of the coarse-scale model. | Zhaoqin Huang Jun Yao Yajun Li Chenchen Wang Xinrui Lv | 2011 | Communications in Computational Physics2011，9，1： | 2 |
| 8 | GRP78 inhibits macrophage adhesion via SR-A显示文摘Class A scavenger receptor(SR-A)plays an important role in macrophage adhesion.However,the underlying mechanism remains unclear.We previously found that 78 kDa glucose-regulated protein(GRP78)inhibited SRA-mediated ligand internalization into macrophage by binding to SR-A.The aim of the study was to investigate whether GRP78 could regulate SR-A-mediated cell adhesion.We demonstrated that GRP78 bound directly to SR-A by fluorescence resonance energy transfer(FRET)assay.Overexpression of GRP78 inhibited macrophage adhesion via SR-A.These results suggest that GRP78 may act as an inhibitor of macrophage adhesion via SR-A. | Hui Bai Nan Li Xiaodan Zhou Chenchen Wang Yan Zhang Xudong Zhu Min Huang Yaoyu Chen Xiaoyu Li Qing Yang Chaojun Li Jingjing Ben Qi Chen | 2014 | The Journal of Biomedical Research2014，28，4： | 2 |
| 9 | Soil phyllosilicate and iron oxide inhibit the quorum sensing of Chromobacterium violaceum显示文摘Microorganisms respond to various adverse environmental conditions and regulate different physiological functions by secreting and sensing signal molecules through quorum sensing(QS)systems.Phyllosilicates and iron oxides present in soils and sediments may have substantial impact on bacterial activity and QS due to their unique reactivity and close association with microorganisms.This research explored the effect of goethite,montmorillonite and kaolinite(0.05–2gL^(–1))on the growth and QS of a bacterial model,Chromobacterium violaceum.The results showed that kaolinite and goethite caused cellular damage at low mineral concentrations.The capacity for violacein production and biofilm formation of C.violaceum were inhibited by the minerals in the order of kaolinite>goethite>montmorillonite.The possible underlying mechanisms for QS inhibition by different minerals were investigated.Specifically,kaolinite repressed QS function through downregulation the expression of signal molecules synthesis gene cviI.Goethite and montmorillonite interfered with QS by adsorption of extracellular signal molecules.This work provides a better understanding of the interactions between bacteria and minerals and proposed that the inhibition of QS system is an ignored mechanism for bacterial toxicity by phyllosilicates and iron oxides. | Shanshan Yang Chenchen Qu Manisha Mukherjee Yichao Wu Qiaoyun Huang Peng Cai | 2021 | Soil Ecology Letters2021，3，1： | 2 |
| 10 | Recent progress in small molecule fluorescent probes for nitroreductase显示文摘Nitroreductase(NTR) is a member of flavin-containing enzymes that exists widely in bacteria. Hypoxia,which is a characteristic of locally advanced solid tumors, resulting from an imbalance between oxygen consumption and supply, can result in NTR overexpression. Using either nicotinamide adenine dinucleotide(NADH) or nicotinamide adenine dinucleotide phosphate(NADPH) as a source of reducing equivalents, NTR can catalyze the reduction of nitroaromatic compounds to the corresponding amines.Based on this reduction mechanism, NTR can be applied not only in the bioremediation and degradation of organic nitrogen compounds, but also in the development of NTR-targeted fluorescent probes to detect the hypoxic status of cancer cells. This review aims to provide a summary of the progress in fluorescent probes for NTR in recent years and elucidate the main fluorescent mechanisms that have been applied to design probes. | Wenjing Qin Chenchen Xu Yanfei Zhao Changmin Yu Sheng Shen Lin Li Wei Huang | 2018 | Chinese Chemical Letters2018，29，10： | 2 |

| 15 | An open-accessed inventory of landslides triggered by the M_(S)6.8 Luding earthquake,China on September 5,2022显示文摘This study constructs a preliminary inventory of landslides triggered by the M_(S) 6.8 Luding earthquake based on field investigation and human-computer interaction visual interpretation on optical satellite images.The results show that this earthquake triggered at least 5007 landslides,with a total landslide area of 17.36 km^(2),of which the smallest landslide area is 65 m^(2)and the largest landslide area reaches 120747 m^(2),with an average landslide area of about 3500 m^(2).The obtained landslides are concentrated in the IX intensity zone and the northeast side of the seismogenic fault,and the area density and point density of landslides are 13.8%,and 35.73 km^(-2) peaks with 2 km as the search radius.It should be noted that the number of landslides obtained in this paper will be lower than the actual situation because some areas are covered by clouds and there are no available post-earthquake remote sensing images.Based on the available post-earthquake remote sensing images,the number of landslides triggered by this earthquake is roughly estimated to be up to 10000.This study can be used to support further research on the distribution pattern and risk evaluation of the coseismic landslides in the region,and the prevention and control of landslide hazards in the seismic area. | Yuandong Huang Chenchen Xie Tao Li Chong Xu Xiangli He Xiaoyi Shao Xiwei Xu Tao Zhan Zhaoning Chen | 2023 | Earthquake Research Advances2023，3，1： | 1 |
| 16 | Modulating the C-terminus of DEP1 synergistically enhances grain quality and yield in rice显示文摘Grain shape is a key breeding target that influences both grain yield and appearance quality in rice. Breeding for long-slender grains is an effective strategy to improve grain quality (Jain et al., 2004;Wang et al., 2012, 2015a). In the past two decades, several quantitative trait loci (QTLs) responsible for grain size and shape have been identified, including GS3 (Fan et al., 2006), GS5 (Li et al., 2011). | Haixiang Huang Yafeng Ye Wenzhen Song Qi Li Ruixi Han Chenchen Wu Shuoxun Wang Jianping Yu Xueying Liu Xiangdong Fu Qian Liu Kun Wu | 2022 | Journal of Genetics and Genomics2022，49，5： | 1 |
| 17 | Generation and application of replication-competent Venus-expressing H5N1,H7N9,and H9N2 influenza A viruses显示文摘The generation and application of replication-competent influenza A virus(IAV) expressing a reporter gene represent a valuable tool to elucidate the mechanism of viral pathogenesis and establish new countermeasures to combat the threat of influenza. Here, replication-competent IAVs with a neuraminidase(NA) segment harboring a fluorescent reporter protein, Venus, were generated in the background of H5N1, H7N9, and H9N2 influenza viruses, the three subtypes of viruses with imminent pandemic potential. All three reporter viruses maintained virion morphology, replicated with similar or slightly reduced titers relative to their parental viruses, and stably expressed the fluorescent signal for at least two passages in embryonated chicken eggs. As a proof of concept, we demonstrated that these reporter viruses,used in combination with a high-content imaging system, can serve as a convenient and rapid tool for the screening of antivirals and host factors involved in the virus life cycle. Moreover, the reporter viruses demonstrated similar growth properties and tissue tropism as their parental viruses in mice, among which the H7N9 NA-Venus virus could potentially be used in ex vivo studies to better understand H7N9 pathogenesis or to develop novel therapeutics. | guangwen wang jie zhang fandi kong qibing li jinliang wang shujie ma yuhui zhao libin liang junping li nan sun lizheng guan yuan zhou chenchen zhou shanyu huang zhigao bu li jiang hualan chen chengjun li | 2018 | Science Bulletin2018，63，3： | 1 |
| 18 | RS-store:RDMA-enabled skiplist-based key-value store for efficient range query显示文摘Many key-value stores use RDMA to optimize the messaging and data transmission between application layer and the storage layer,most of which only provide point-wise operations.Skiplist-based store can support both point operations and range queries,but its CPU-intensive access operations combined with the high-speed network will easily lead to the storage layer reaches CPU bottlenecks.The common solution to this problem is offloading some operations into the application layer and using RDMA bypassing CPU to directly perform remote access,but this method is only used in the hash tablebased store.In this paper,we present RS-store,a skiplist-based key-value store with RDMA,which can overcome the CPU handle of the storage layer by enabling two access modes:local access and remote access.In RS-store,we redesign a novel data structure R-skiplist to save the communication cost in remote access,and implement a latch-free concurrency control mechanism to ensure all the concurrency during two access modes.RS-store also supports client-active range query which can reduce the storage layer’s CPU consumption.At last,we evaluate RS-store on an RDMA-capable cluster.Experimental results show that RS-store achieves up to 2x improvements over RDMA-enabled RocksDB on the throughput and application’s scalability. | Chenchen HUANG Huiqi HU Xuecheng Qi Xuan ZHOU Aoying ZHOU | 2021 | Frontiers of Computer Science2021，15，6： | 0 |
| 19 | The complete mitochondrial genome of Parnassius actius(Lepidoptera: Papilionidae: Parnassinae) with the related phylogenetic analysis显示文摘In this study, the complete mitochondrial genome of Parnassius actius(Lepidoptera: Papilionidae: Parnassinae) was reported. Meanwhile, the phylogenetic position of this Apollo species was inferred from this sequence combined with other available related sequence data. The results showed that the whole mitogenome is 15,386 bp in length, containing 13 typical protein-coding genes(PCGs), 22 transfer RNA genes(t RNAs), two ribosomal RNA genes(r RNAs) and a noncoding control region(A+T-rich region). The mitogenomic gene orientation and arrangement are the same with other sequenced Parnassius species. Thirteen protein coding genes is 11,195 bp in size, encoding 3,720 amino acids totally; the lr RNA and sr RNA genes are 1,351 bp and 779 bp, respectively. Eleven intergenic spacers ranging from 1 to 40 bp(129 bp in total), 10 overlapping regions from 1 to 8 bp(26 bp in total), and a 504 bp A+T-rich region harboring some Parnassius-specific sequences are scattered throughout the whole mitogenome. The maximum likelihood and Bayesian phylogenetic analyses showed that the genus Parnassiusof this study contained five major clades which can be categorized into the eight subgenera reported by the previous molecular studies; additionally, the P. actius was shown to be more closely related to P. nomion than other Parnassius species, suggesting that the P. actius stands as an effective species with its phylogenetic position awaiting further studies. | Bin Zheng Yunliang Wang Chenchen Xia Dunyuan Huang Yan Cao Jiasheng Hao Chaodong Zhu | 2018 | Zoological Systematics2018，43，1： | 0 |
| 20 | LncRNA IDH1-AS1 sponges miR-518c-5p to suppress proliferation of epithelial ovarian cancer cell by targeting RMB47显示文摘Long noncoding RNA(lncRNA)IDH1 antisense RNA 1(IDH1-AS1)is involved in the progression of multiple cancers,but its role in epithelial ovarian cancer(EOC)is unknown.Therefore,we investigated the expression levels of IDH1-AS1 in EOC cells and normal ovarian epithelial cells by quantitative real-time PCR(qPCR).We first evaluated the effects of IDH1-AS1 on the proliferation,migration,and invasion of EOC cells through cell counting kit-8,colony formation,EdU,transwell,wound-healing,and xenograft assays.We then explored the downstream targets of IDH1-AS1 and verified the results by a dual-luciferase reporter,qPCR,rescue experiments,and Western blotting.We found that the expression levels of IDH1-AS1 were lower in EOC cells than in normal ovarian epithelial cells.High IDH1-AS1 expression of EOC patients from the Gene Expression Profiling Interactive Analysis database indicated a favorable prognosis,because IDH1-AS1 inhibited cell proliferation and xenograft tumor growth of EOC.IDH1-AS1 sponged miR-518c-5p whose overexpression promoted EOC cell proliferation.The miR-518c-5p mimic also reversed the proliferation-inhibiting effect induced by IDH1-AS1 overexpression.Furthermore,we found that RNA binding motif protein 47(RBM47)was the downstream target of miR-518c-5p,that upregulation of RBM47 inhibited EOC cell proliferation,and that RBM47 overexpressing plasmid counteracted the proliferation-promoting effect caused by the IDH1-AS1 knockdown.Taken together,IDH1-AS1 may suppress EOC cell proliferation and tumor growth via the miR-518c-5p/RBM47 axis. | Juan Zhou Yiran Xu Luyao Wang Yu Cong Ke Huang Xinxing Pan Guangquan Liu Wenqu Li Chenchen Dai Pengfei Xu Xuemei Jia | 2024 | The Journal of Biomedical Research2024，38，1： | 0 |
