| 1 | Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。 | You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU | 2014 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014，15，1： | 23 |

| 3 | Ent-11α-Hydroxy-15-oxo-kaur-16-en-19-oic-acid Inhibits Growth of Human Lung Cancer A549 Cells by Arresting Cell Cycle and Triggering Apoptosis显示文摘Objective: To examine the apoptotic effect of ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F), a compound isolated from Pteris semipinnata L (PsL), in human lung cancer A549 cells. Methods: A549 cells were treated with 5F (0-80 μg/ml) for different time periods. Cytotoxicity was examined using a MTT method. Cell cycle was examined using propidium iodide staining. Apoptosis was examined using Hoechst 33258 staining, enzyme-linked immunosorbent assay (ELISA) and caspase-3 activity analysis. Expression of representative apoptosis-related proteins was evaluated by Western blot analysis. Reactive oxygen species (ROS) level was measured using standard protocols. Potential interaction of 5F with cisplatin was also examined. Results: 5F inhibited the proliferation of A549 cells in a concentration-and time-dependent manner. 5F increased the accumulation of cells in sub-G1 phase and arrested the cells in the G2 phase. Exposure to 5F induced morphological changes and DNA fragmentation that are characteristic of apoptosis. The expression of p21 was increased. 5F exposure also increased Bax expression, release of cytochrome c and apoptosis inducing factor (AIF), and activation of caspase-3. 5F significantly sensitized the cells to cisplatin toxicity. Interestingly, treatment with 5F did not increase ROS, but reduced ROS production induced by cisplatin. Conclusion: 5F could inhibit the proliferation of A549 cells by arresting the cells in G2 phase and by inducing mitochondrial-mediated apoptosis. | Li Li George G Chen Ying-nian Lu Yi Liu Ke-feng Wu Xian-ling Gong Zhan-ping Gou Ming-yue Li Nian-ci Liang | 2012 | Chinese Journal of Cancer Research2012，24，2： | 10 |
| 4 | SERK Receptor-like Kinases Control Division Patterns of Vascular Precursors and Ground Tissue Stem Cells during Embryo Development in Arabidopsis显示文摘During embryo development, the vascular precursors and ground tissue stem cells divide to renew them-selves and produce the vascular tissue, endodermal cells, and cortical cells. However, the molecular mech-anisms regulating division of these stem cells have remained largely elusive. In this study, we show that loss of function of SOMATIC EMBRYOGENESIS RECEPTOR-UKE KINASE (SERK) genes results in aberrant em-bryo development. Fewer cortical, endodermal, and vascular cells are generated in the embryos of serk1 serk2bak1 triple mutants. WUSCHEL-RELATED HOMBOBOX5 (WOXS) is ectopically expressed in vascular cells of serkl serk2 bak1 embryos. The first transverse division of vascular precursors in mid-globular em-bryos and second asymmetric division of ground tissue stem cells in early-heart embryos are abnormally altered to a longitudinal division. The embryo defects can be partially rescued by constitutively activated mitogen-activated protein kinase (MAPK) kinase kinase YODA (YDA) and MAPK kinase MKK5. Taken together, our results reveal that SERK-mediated signals regulate division patterns of vascular precursors and ground tissue stem cells, likely via the YDA-MKK4/5 cascade, during embryo development. | Huiqiang Li Zeping Cai Xiaojuan Wang Meizhen Li Yanwei Cui Nan Cui Fei Yang Mingsong Zhu Junxiang Zhao Wenbin Du Kai He Jing Yi Frans E.Tax Suiwen Hou Jia Li Xiaoping Gou | 2019 | Molecular Plant2019，12，7： | 7 |
| 5 | Establishment of a transgenic mouse model with liver-specific expression of secretory immunoglobulin D显示文摘Mutation of mevalonate kinase(MVK) is thought to account for most cases of hyperimmunoglobulinemia D syndrome(HIDS) with recurrent fever.However,its mechanism and the relationship between elevated serum immunoglobulin D(IgD) and the clinical features of HIDS are unclear.In this study,we generated by fusion PCR a vector to express high levels of chimeric secretory IgD(csIgD) specifically in the liver.We then generated seven founder lines of transgenic mice by co-microinjection,and verified them using genomic PCR and Southern blotting.We detected the expression of csIgD by reverse transcription PCR,quantitative PCR,western blotting,and enzyme-linked immunosorbent assays.We demonstrated that csIgD could be specifically and stably expressed in the liver.We used flow cytometry to show that overexpression of csIgD in the bone marrow and spleen cells had no effect on B cell development.Morphologic and anatomical observation of the transgenic mice revealed skin damage,hepatosplenomegaly,and nephromegaly in some transgenic mice;in these mice,pathological sections showed high levels of cell necrosis and protein-like sediments in the liver,spleen,and kidney.We demonstrated that the genomic insertion sites of the transgenes did not disrupt the MVK gene on mouse chromosome 5.This transgenic mouse will be useful to explore the pathogenesis of HIDS. | WANG Ping WEI ZhiGuo YAN BoWen HUANG Tan GOU KeMian DAI YunPing ZHENG Min WANG MeiLi CHENG XueQian WANG XiFeng XU Chen SUN Yi | 2012 | Science China(Life Sciences)2012，55，3： | 6 |
| 6 | Risk factors for mortality at beginning of maintenance hemodialysis显示文摘Hemodialysis(HD)is a crucial renal replacement therapy for patients with end-stage renal disease.Despite improvements in dialysis technology,mortality for maintenance HD(MHD)patients remains high.To improve the quality of life among MHD patients,it is necessary to examine the risk factors associated with mortality.In this study,we retrospectively analyzed patients5 conditions at the beginning of dialysis and assessed the risk factors for mortality in MHD patients treated at the Center for Hemodialysis in West China Hospital,Sichuan University,China.The aim of this study was to identify significant risk factors to guide the treatment of MHD patients and targeted early preventions to improve prognosis. | Shao-Bin Yu Huai-Hong Yuan Stephen Salerno Shen-Ju Gou Wen-Wen Chen Hong-Liu Yang Yi Li Ping Fu | 2020 | Chinese Medical Journal2020，，7： | 5 |
| 7 | A structural and data-driven approach to engineering a plant cytochrome P450 enzyme显示文摘Functional manipulation of biosynthetic enzymes such as cytochrome P450 s(or P450 s) has attracted great interest in metabolic engineering of plant natural products.Cucurbitacins and mogrosides are plant triterpenoids that share the same backbone but display contrasting bioactivities.This structural and functional diversity of the two metabolites can be manipulated by engineering P450 s.However,the functional redesign of P450 s through directed evolution(DE) or structure-guided protein engineering is time consuming and challenging,often because of a lack of high-throughput screening methods and crystal structures of P450 s.In this study,we used an integrated approach combining computational protein design,evolutionary information,and experimental data-driven optimization to alter the substrate specificity of a multifunctional P450(CYP87 D20)from cucumber.After three rounds of iterative design and evaluation of 96 protein variants,CYP87 D20,which is involved in the cucurbitacin C biosynthetic pathway,was successfully transformed into a P450 mono-oxygenase that performs a single specific hydroxylation at C11 of cucurbitadienol.This integrated P450-engineering approach can be further applied to create a de novo pathway to produce mogrol,the precursor of the natural sweetener mogroside,or to alter the structural diversity of plant triterpenoids by functionally manipulating other P450 s. | Dawei Li Yongshuo Ma Yuan Zhou Junbo Gou Yang Zhong Lingling Zhao Lida Han Sergey Ovchinnikov Ling Ma Sanwen Huang Per Greisen Yi Shang | 2019 | Science China(Life Sciences)2019，62，7： | 5 |
| 8 | Tuning filament composition and microstructure of 3D-printed bioceramic scaffolds facilitate bone defect regeneration and repair显示文摘It is still a challenge to optimize the component distribution and microporous structures in scaffolds for tailoring biodegradation(ion releasing)and enhancing bone defect repair within an expected time stage.Herein,the core–shell-typed nonstoichiometric wollastonite(4%and 10%Mg-doping calcium silicate;CSiMg4,CSiMg10)macroporous scaffolds with microporous shells(adding~μ10 μm PS microspheres into shell-layer slurry)were fabricated via 3D printing.The initial mechanical properties and bio-dissolution(ion releasing)in vitro,and osteogenic capacity in vivo of the bioceramic scaffolds were evaluated systematically.It was shown that endowing high-density micropores in the sparingly dissolvable CSiMg10 or dissolvable CSiMg4 shell layer inevitably led to nearly 30%reduction of compressive strength,but such micropores could readily tune the ion release behaviour of the scaffolds(CSiMg4@CSiMg10 vs.CSiMg4@CSiMg10-p;CSiMg10@CSiMg4 vs.CSiMg10@CSiMg4-p).Based on the in rabbit femoral bone defect repair model,the 3D μCT reconstruction and histological observation demonstrated that the CSiMg4@CSiMg10-p scaffolds displayed markedly higher osteogenic capability than the other scaffolds after 12weeks of implantation.It demonstrated that core–shell bioceramic 3D printing technique can be developed to fabricate single-phase or biphasic bioactive ceramic scaffolds with accurately tailored filament biodegradation for promoting bone defect regeneration and repair in some specific pathological conditions. | Yi Chen Jiaping Huang Jiamei Liu Yingming Wei Xianyan Yang Lihong Lei Lili Chen Yanmin Wu Zhongru Gou | 2021 | Regenerative Biomaterials2021，8，2： | 3 |

| 10 | Landing site topographic mapping and rover localization for Chang’e-4 mission显示文摘This paper presents the techniques and results of landing-site topographic mapping and rover localization using orbital,descent and rover images in the Chang’e-4 mission.High-resolution maps of the landing site are generated from orbital and descent images.Local digital elevation models and digital orthophoto maps with 0.02 m resolution are generated at each waypoint.The location of the lander is determined as(177.588?E,45.457?S)using festure-matching techniques.The cross-site visual localization method is routinely used to localize the rover at each waypoint to reduce error accumulation from wheel slippage and IMU drift in dead reckoning.After the first five lunar days,the rover travels 186.66 m from the lander,according to the cross-site visual localization.The developed methods and results have been directly utilized to support the mission’s operations.The maps and localization information are also valuable for supporting multiple scientific explorations of the landing site. | Zhaoqin LIU Kaichang DI Jian LI Jianfeng XIE Xiaofeng CUI Luhua XI Wenhui WAN Man PENG Bin LIU Yexin WANG Sheng GOU Zongyu YUE Tianyi YU Lichun LI Jia WANG Chuankai LIU Xin XIN Mengna JIA Zheng BO Jia LIU Runzhi WANG Shengli NIU Kuan ZHANG Yi YOU Bing LIU Jiangang LIU | 2020 | Science China(Information Sciences)2020，63，4： | 3 |
| 11 | Twelve-year profile of screening results of retinopathy of prematurity at a tertiary care institute in Northwest China显示文摘AIM:To report the changes in detection rate and characteristics of retinopathy of prematurity(ROP)in infants,during a 12-year period in Northwest China.METHODS:The medical records of infants were retrospectively collected and reviewed using an established clinical database.The detection rate and severity of ROP were compared between two consecutive periods(P1:2008-2013,P2:2014-2019).Gender,gestational age(GA),birth weight(BW),multiple births,delivery pattern,and postmenstrual age of the first fundus screen were analyzed in all visiting infants.RESULTS:During the 12-year study period,7832 infants were initially included;among them,1266(16.16%)were diagnosed with ROP,441 of whom(5.63%)developed severe ROP.Throughout the study period,the total number of infants being screened showed a trend of slight fluctuation after a rapid increase;however,an annual increase was observed in the number of infants diagnosed with ROP and severe ROP.The proportion of each stage at the first screening of infants with ROP was stable.The detection rate of ROP increased from 2.33%in 2008 to 16.18%in 2010,decreased to 10.73%in 2014,and then increased to 27.47%in 2019.For severe ROP,the detection rate gradually increased from 0 in 2008 to 12.49%in 2019.Among the infants with ROP,96(7.58%)did not meet the screening criteria set by the Chinese Medical Association in 2014(GA<32wk,or BW<2000 g);among them,14(1.11%)needed treatment because of severe ROP.CONCLUSION:From 2008 to 2019,the detection rates of ROP and severe ROP in infants screened in Northwest China were 16.16%and 5.63%,respectively.The characteristics of the ROP infants were similar to those in other middle-income regions.The'tertiary prevention network of ROP'is a potentially effective screening approach. | Hong-Xiang Yan Man-Hong Li Liang Wang Lei Wu Jing Fan Yi Zhou Kai-Li Gou Zi-Feng Zhang Yu-Sheng Wang | 2022 | International Journal of Ophthalmology(English edition)2022，15，2： | 3 |
| 12 | Multi-responsive nanotheranostics with enhanced tumor penetration and oxygen self-producing capacities for multimodal synergistic cancer therapy显示文摘Incorporation of multiple functions into one nanoplatform can improve cancer diagnostic efficacy and enhance anti-cancer outcomes. Here, we constructed doxorubicin(DOX)-loaded silk fibroinbased nanoparticles(NPs) with surface functionalization by photosensitizer(N770). The obtained nanotheranostics(N770-DOX@NPs) had desirable particle size(157 nm) and negative surface charge(-25 m V). These NPs presented excellent oxygen-generating capacity and responded to a quadruple of stimuli(acidic solution, reactive oxygen species, glutathione, and hyperthermia). Surface functionalization of DOX@NPs with N770 could endow them with active internalization by cancerous cell lines, but not by normal cells. Furthermore, the intracellular NPs were found to be preferentially retained in mitochondria, which were also efficient for near-infrared(NIR) fluorescence imaging, photothermal imaging,and photoacoustic imaging. Meanwhile, DOX could spontaneously accumulate in the nucleus. Importantly, a mouse test group treated with N770-DOX@NPs plus NIR irradiation achieved the best tumorretardation effect among all treatment groups based on tumor-bearing mouse models and a patientderived xenograft model, demonstrating the unprecedented therapeutic effects of trimodal imagingguided mitochondrial phototherapy(photothermal therapy and photodynamic therapy) and chemotherapy.Therefore, the present study brings new insight into the exploitation of an easy-to-use, versatile, and robust nanoplatform for programmable targeting, imaging, and applying synergistic therapy to tumors. | Shuangquan Gou Nanxi Chen Xiaoai Wu Menghang Zu Shixiong Yi Binwu Ying Fangyin Dai Bowen Ke Bo Xiao | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 2 |
| 13 | An improved Tet-on system in micro RNA overexpression and CRISPR/Cas9-mediated gene editing显示文摘Background: Tetracycline(Tet)-regulated expression system has become a widely applied tool to control gene activity. This study aimed to improve the Tet-on system with superior regulatory characteristics.Results: By comprehensively comparing factors of transactivators, Tet-responsive elements(TREs), orientations of induced expression cassette, and promoters controlling the transactivator, we developed an optimal Tet-on system with enhanced inducible efficiency and lower leakiness. With the system, we successfully performed effective inducible and reversible expression of micro RNA, and presented a more precise and easily reproducible fine-tuning for confirming the target of a mi RNA. Finally, the system was applied in CRISPR/Cas9-mediated knockout of nuclear factor of activated T cells-5(NFAT5), a protective transcription factor in cellular osmoregulation.Conclusions: This study established an improved Tet-on system for powerful and stringent gene regulation in functional genetic studies. | Kang Kang Lian Huang Qing Li Xiaoyun Liao Quanjin Dang Yi Yang Jun Luo Yan Zeng Li Li Deming Gou | 2019 | Journal of Animal Science and Biotechnology2019，10，4： | 2 |
| 14 | Conserved and differentiated functions of CIK receptor kinases in modulating stem cell signaling in Arabidopsis显示文摘The shoot apical meristem(SAM)and root apical meristem(RAM)act as pools of stem cells that give rise to aboveground and underground tissues and organs in higher plants,respectively.The CLAVATA3(CLV3)-WUSCHEL(WUS)negative-feedback loop acts as a core pathway controlling SAM homeostasis,while CLV3/EMBRYO SURROUNDING REGION(ESR)40(CLE40)and WUSCHEL-RELATED HOMEOBOX5(WOX5),homologs of CLV3 and WUS,direct columella stem cell fate.Moreover,CLV3 INSENSITIVE KINASES(CIKs)have been shown to be essential for maintaining SAM homeostasis,whereas whether they regulate the distal root meristem remains to be elucidated.Here,we report that CIKs are indispensable for transducing the CLE40 signal to maintain homeostasis of the distal root meristem.We found that the cik mutant roots displayed disrupted quiescent center and delayed columella stem cell(CSC)differentiation.Biochemical assays demonstrated that CIKs interact with ARABIDOPSIS CRINKLY4(ACR4)in a ligand-independent manner and can be phosphorylated by ACR4 in vitro.In addition,the phosphorylation of CIKs can be rapidly induced by CLE40,which partially depends on ACR4.Although CIKs act as conserved and redundant regulators in the SAM and RAM,our results demonstrated that they exhibit differentiated functions in these meristems. | Yafen Zhu Chong Hu Yanwei Cui Li Zeng Sunjingnan Li Mingsong Zhu Fanhui Meng Shuting Huang Li Long Jing Yi Jia Li Xiaoping Gou | 2021 | Molecular Plant2021，14，7： | 2 |
