| 1 | 42,573 cases of hepatectomy in China: a multicenter retrospective investigation显示文摘Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival. | Binhao Zhang Bixiang Zhang Zhiwei Zhang Zhiyong Huang Yifa Chen Minshan Chen Ping Bie Baogang Peng Liqun Wu Zhiming Wang Bo Li Jia Fan Lunxiu Qin Ping Chen Jingfeng Liu Zhe Tang Jun Niu Xinmin Yin Deyu Li Songqing He Bin Jiang Yilei Mao Weiping Zhou Xiaoping Chen | 2018 | Science China(Life Sciences)2018,61,6: | 39 |
| 2 | Somatic Embryogenesis Receptor Kinases Control Root Development Mainly via Brassinosteroid-Independent Actions in Arabidopsis thaliana显示文摘Brassinosteroids(BRs),a group of plant steroidal hormones,play critical roles in many aspects of plant growth and development.Previous studies showed that BRI1-mediated BR signaling regulates cell division and differentiation during Arabidopsis root development via interplaying with auxin and other phytohormones.Arabidopsis somatic embryogenesis receptor-like kinases(SERKs),as co-receptors of BRI1,were found to play a fundamental role in an early activation step of BR signaling pathway.Here we report a novel function of SERKs in regulating Arabidopsis root development.Genetic analyses indicated that SERKs control root growth mainly via a BR-independent pathway.Although BR signaling pathway is completely disrupted in the serk1 bak1 bkk1 triple mutant,the root growth of the triple mutant is much severely damaged than the BR deficiency or signaling null mutants.More detailed analyses indicated that the triple mutant exhibited drastically reduced expression of a number of genes critical to polar auxin transport,cell cycle,endodermis development and root meristem differentiation,which were not observed in null BR biosynthesis mutant cpd and null BR signaling mutant bri1-701. | Junbo Du Hongju Yin Shasha Zhang Zhuoyun Wei Baolin Zhao Jinghua Zhang Xiaoping Gou Honghui Lin Jia Li | 2012 | Journal of Integrative Plant Biology2012,54,6: | 22 |
| 3 | The China Alzheimer Report 2022显示文摘China’s population has rapidly aged over the recent decades of social and economic development as neurodegenerative disorders have proliferated,especially Alzheimer’s disease(AD)and related dementias(ADRD).AD’s incidence rate,morbidity,and mortality have steadily increased to make it presently the fifth leading cause of death among urban and rural residents in China and magnify the resulting financial burdens on individuals,families and society.The‘Healthy China Action’plan of 2019-2030 promotes the transition from disease treatment to health maintenance for this expanding population with ADRD.This report describes related epidemiological trends,evaluates the economic burden of the disease,outlines current clinical diagnosis and treatment status and delineates existing available public health resources.More specifically,it examines the public health impact of ADRD,including prevalence,mortality,costs,usage of care,and the overall effect on caregivers and society.In addition,this special report presents technical guidance and supports for the prevention and treatment of AD,provides expertise to guide relevant governmental healthcare policy development and suggests an information platform for international exchange and cooperation. | Rujing Ren Jinlei Qi Shaohui Lin Xinya Liu Peng Yin Zhihui Wang Ran Tang Jintao Wang Qiang Huang Jianping Li Xinyi Xie Yongbo Hu Shishuang Cui Yuan Zhu Xiaoping Yu Pengfei Wang Yikang Zhu Yiran Wang Yanyan Huang Yisong Hu Ying Wang Chunbo Li Maigeng Zhou Gang Wang | 2022 | General Psychiatry2022,35,1: | 20 |

| 5 | Newborn screening with targeted sequencing:a multicenter investigation and a pilot clinical study in China显示文摘Different newborn screening(NBS) programs have been practiced in many countries since the 1960 s. It is of considerable interest whether next-generation sequencing is applicable in NBS. We have developed a panel of 465 causative genes for 596 early-onset, relatively high incidence, and potentially actionable severe inherited diseases in our Newborn Screening with Targeted Sequencing(NESTS) program to screen 11,484 babies in 8 Women and Children’s hospitals nationwide in China retrospectively. The positive rate from preliminary screening of NESTS was 7.85%(902/11,484). With 45.89%(414/902) follow-up of preliminary positive cases, the overall clinically confirmative diagnosis rate of monogenic disorders was 12.07%(50/414), estimating an average of 0.95%(7.85% × 12.07%) clinical diagnosis rate, suggesting that monogenic disorders account for a considerable proportion of birth defects. The disease/gene spectrum varied in different regions of China. NESTS was implemented in a hospital by screening 3923 newborns to evaluate its clinical application. The turn-around time of a primary report, including the sequencing period of < 7 days, was within 11 days by our automatic interpretation pipeline. Our results suggest that NESTS is feasible and cost-effective as a first-tier NBS program, which will change the status of current clinical practice of NBS in China. | Chanjuan Hao Ruolan Guo Xuyun Hu Zhan Qi Qi Guo Xuanshi Liu Yuanhu Liu Yanhua Sun Xiaofen Zhang Feng Jin Xiujie Wu Ren Cai Dingyuan Zeng Xijiang Hu Xiaohua Wang Xiaoping Ji Wenjie Li Quansheng Xing Lanfang Mu Xiulian Jiang Xue Yang Weimin Yang Yan Zhang Qianli Yin Xin Ni Wei Li | 2022 | Journal of Genetics and Genomics2022,49,1: | 7 |
| 6 | Field test of HTS receivers on CDMA demonstration cluster in China显示文摘This paper presents the field test of our first demonstration cluster with five base stations (BTS) on code division multiple access (CDMA) wireless communication in China, while each BTS was installed with a high temperature superconductor (HTS) receiver. The HTS receivers have the same centre frequency of 830 MHz, a bandwidth of 13 MHz, and a noise figure (NF) of 0.9 dB. After the conventional receivers in the BTSs were replaced by the HTS receivers, a consequent drive test was carried out. A 2.35 dB decrease of the mean mobile transmit power was observed in the demonstration cluster. | WEI Bin GUO XuBo PIAO YunLong JIN ShiChao ZHANG XiaoPing GAO LongMa PENG HuiLi YIN ZheSheng CAO BiSong | 2009 | Chinese Science Bulletin2009,54,4: | 7 |
| 7 | Field trial of an HTS filter system on a CDMA base station显示文摘This paper presents the field trial results of a high temperature superconductor filter system (HTSFS) in a code division multiple access (CDMA) mobile communication base station (BTS) in Tangshan, China. The center frequency of the HTSFS is 830 MHz with 1.4% fractional bandwidth. The noise figure (NF) of the HTSFS, including connectors and cables, is 0.8 dB. The field trial results show that after the HTSFS was installed in the receiver front-end of a CDMA base station, the transmitting power of handset was decreased by 3.1 dB on average. Up to now, the HTSFS has been running steadily in the base station for more than 22 months, demonstrating the reliability and stability of the system. | YIN ZheSheng WEI Bin CAO BiSong WANG Xin GUO XuBo ZHANG XiaoPing GAO LongMa PIAO YunLong ZHU MaFeng LIANG Yong WANG Fan H.

| 8 | Fe5C2 nanoparticles as low-cost HER electrocatalyst:the importance of Co substitution显示文摘Constructing and understanding the doping effect of secondary metal in transition metal carbide(TMC)catalysts is pivotal for the design of low-cost hydrogen evolution reaction(HER) electrocatalysts. In this work, we developed a wet-chemistry strategy for synthesizing Co-modified Fe_5C_2 nanoparticles((Fe_(1-x)Cox)_5C_2 NPs) as highly active HER electrocatalysts in basic solution. The structure of(Fe_(1-x)Cox)_5C_2 NPs was characterized by X-ray diffraction(XRD), extended X-ray absorption fine structure spectra(EXAFS) and scanning/transmission electron microscopy(S/TEM), indicating that the isomorphous substitution of cobalt in the lattice of Fe_5C_2.(Fe_(0.75) Co_(0.25))_5C_2 exhibited the best HER activity(174 mV for j = -10 mA/cm^2). Computational calculation results indicate that Co provides the most active site for HER. X-ray adsorption spectra(XAS) studies further suggested that the electron transfer in Fe–C bonds are enhanced by the substitution of Co, which modulates the hydrogen adsorption on the adjacent electronic-enriched carbon, and therefore promotes HER activity. Our results affirm the design of lowcost bimetallic TMCs based HER catalysts. | Siwei Li Pengju Ren Ce Yang Xi Liu Zhen Yin Weizhen Li Hanjun Yang Jian Li Xiaoping Wang Yi Wang Ruochen Cao Lili Lin Siyu Yao Xiaodong Wen Ding Ma | 2018 | Science Bulletin2018,63,20: | 6 |

| 13 | Spatial and Seasonal Variations of Nutrients in Sediment Profiles and Their Sediment-Water Fluxes in the Pearl River Estuary,Southern China显示文摘Three cruises were launched in the Pearl River Estuary(PRE)in 2005 to investigate the biogeochemical cycling of nutrients associated with early diagenesis related to degradation of organic matter.Seasonal and spatial variations of pore water nutrient concentrations and profile patterns in sediments were studied.Nutrient fluxes at the sediment-water interface(SWI)were measured by incubation experiments,and we here discussed the accumulation and transformation processes of nutrients at the SWI.The nutrients generally decreased from the Pearl River outlets downstream,indicating anthropogenic influences on the nutrient inputs in the estuary.NO3-N concentration was the highest of the three forms of DIN(dissolved inorganic nitrogen,the sum of NH4-N,NO3-N and NO2-N)in the overlying water,and NH4-N was the main component of DIN in pore water.The gradual increase of NH4-N and the rapid decrease of NO3-N with sediment depth provided the evidence for anaerobic conditions below the SWI.Negative fluxes of NO3-N and positive fluxes of NH4-N were commonly observed,suggesting the denitrification of NO3-N at the SWI.The DIN flux direction suggested that the sediment was the sink of DIN in spring,however,the sediment was generally the source of DIN in summer and winter.PO4-P distribution patterns were distinct while SiO4-Si inconspicuously varied in sediment profiles in different seasons.The flux results indicated that PO4-P mainly diffused from the water column to the sediment while SiO4-Si mainly diffused from the sediment to the water column.Generally,the incubated fluxes were the coupling of diffusion,bioturbation and biochemical reactions,and were relatively accurate in this study. | Ling Zhang Lu Wang Kedong Yin Ying Lü Yongqiang Yang Xiaoping Huang | 2014 | Journal of Earth Science2014,25,1: | 5 |

| 15 | The role of pathological tau in synaptic dysfunction in Alzheimer’s diseases显示文摘Alzheimer's disease(AD)is a neurodegenerative disease characterized by progressive cognitive decline,accompanied by amyloid-β(Aβ)overload and hyperphosphorylated tau accumulation in the brain.Synaptic dysfunction,an important pathological hallmark in AD;is recognized as the main cause of the cognitive impairments.Accumulating evidence suggests that synaptic dysfunction could be an early pathological event in AD.Pathological tau,which is detached from axonal microtubules and mislocalized into pre-and postsynaptic neuronal compartments,is suggested to induce synaptic dysfunction in several ways,including reducing mobility and release of presynaptic vesicles,decreasing glutamatergic receptors,impairing the maturation of dendritic spines at postsynaptic terminals,disrupting mitochondrial transport and function in synapses,and promoting the phagocytosis of synapses by microglia.Here,we review the current understanding of how pathological tau mediates synaptic dysfunction and contributes to cognitive decline in AD.We propose that elucidating the mechanism by which pathological tau impairs synaptic function is essential for exploring novel therapeutic strategies for AD. | Moxin Wu Manqing Zhang Xiaoping Yin Kai Chen Zhijian Hu Qin Zhou Xianming Cao Zhiying Chen Dan Liu | 2021 | Translational Neurodegeneration2021,10,4: | 4 |
| 16 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022,11,2: | 4 |
| 17 | Upconversion nanoparticles@AgBiS_(2) core-shell nanoparticles with cancer-cell-specific cytotoxicity for combined photothermal and photodynamic therapy of cancers显示文摘UCNPs@AgBiS_(2) core-shell nanoparticles that AgBiS_(2) coated on the surface of upconversion nanoparticles (UCNPs) was successfully prepared through an ion exchange reaction. The photothermal conversion efficiency of AgBiS_(2) can be improved from 14.7% to 45% due to the cross relaxation between Nd ions and AgBiS_(2). The doping concentration of Nd ions played a critical role in the production of reactive oxygen species (ROS) and enhanced the photothermal conversion efficiency. The NaYF4:Yb/Er/Nd@NaYF4:Nd nanoparticles endows strong upcon-version emissions when the doped concentration of Nd ions is 1% in the inner core, which excites the AgBiS_(2) shell to produce ROS for photodynamic therapy (PDT) of cancer cells. As a result, the as-prepared NaYF4:Yb/Er/ Nd@NaYF4:Nd@AgBiS_(2) core-shell nanoparticles showed combined photothermal/photodynamic therapy (PTT/ PDT) against malignant tumors. This work provides an alternative near-infrared light-active multimodal nano-structures for applications such as fighting against cancers. | Zhaoyou Chu Tian Tian Zhenchao Tao Juan Yang Benjin Chen Hao Chen Wanni Wang Peiqun Yin Xiaoping Xia Hua Wang Haisheng Qian | 2022 | Bioactive Materials2022,7,11: | 3 |
| 18 | Detection and Initial Response to a Type 2 Vaccine-Derived Poliovirus—Sichuan Province,China,2019显示文摘What is already known about this topic?After the type 2 strain of the live,attenuated poliovirus vaccine was withdrawn globally in 2016,any identification of a type 2 poliovirus is a Public Health Emergency of International Concern.A vaccinederived type 2 poliovirus(VDPV2)was identified in Sichuan,prompting an urgent,comprehensive investigation and response.What is added by this report?Type 2 monovalent,live,attenuated oral poliovirus vaccine(mOPV2)is being used to respond to the numerous VDPV2 outbreaks seen around the world.In contrast,the response in Sichuan used Sabin strain inactivated poliovirus(sIPV)to stop circulation of the VDPV2.In the 6 months following the vaccination response,there have been no VDPV2s detected in Sichuan,despite extensive search.What are the implications for public health practices?Further search for the VDPV2 must continue in order to determine whether transmission has been stopped.The ongoing investigation and response to the Sichuan VDPV2 is providing evidence to the Global Polio Eradication Initiative on managing VDPV2 outbreaks. | Jiushun Zhou Ning Wen Yong Zhang Qi Qi Chunxiang Fan Dongmei Yan Xiaoping Zhu Lixin Hao Shuangli Zhu Yu Liu Xiaozhen Ma Chao Ma Lei Nan Yong Chen Qianli Ma Cheng Wang Kun Deng Lei Cao Ge Shao Xianxiang Ding Hong Yang Zhijie An Lance ERodewald Aiqiang Xu Huaqing Wang Zijian Feng Zundong Yin Xianping Wu Wenbo Xu | 2020 | China CDC weekly2020,2,11: | 3 |
| 19 | A Novel Low Density Parity Check Coded Differential Amplitude and Pulse Position Modulation Free-Space Optical System for Turbulent Channel显示文摘Based on the proposed partly equidifferent mapping and its specific Differential Amplitude and Pulse Position Modulation(DAPPM) demodulation, a modified FSO scheme for turbulent channel is designed and analyzed. The novel Low Density Parity Check(LDPC) coded 4×4 and 4×8 DAPPM Free-Space Optical communication(FSO) system is constructed. The Monte Carlo simulation results show approximately 2d B transmit power reduction against classical LDPC-DAPPM at the identical Bit-Error-Rate in strong turbulent channel. The proposed partly equidifferent mapping is compatible with other modulations, so it enables widespread adoption in other coded FSO systems. | Yin Liang Hua Zhang Limin Chen Xiaoping Liu Xuehong Lin | 2017 | China Communications2017,14,3: | 3 |
| 20 | Fine mapping of the sex locus in Salix triandra confirms a consistent sex determination mechanism in genus Salix显示文摘Salix triandra belongs to section Amygdalinae in genus Salix,which is in a different section from the willow species in which sex determination has been well studied.Studying sex determination in distantly related willow species will help to clarify whether the sexes of different willows arise through a common sex determination system.For this purpose,we generated an intraspecific full-sib F1 population for S.triandra and constructed high-density genetic linkage maps for the crossing parents using restriction site-associated DNA sequencing and following a two-way pseudo-testcross strategy.With the established maps,the sex locus was positioned in linkage group XV only in the maternal map,and no sex linkage was detected in the paternal map.Consistent with previous findings in other willow species,our study showed that chromosome XV was the incipient sex chromosome and that females were the heterogametic sex in S.triandra.Therefore,sex in this willow species is also determined through a ZW sex determination system.We further performed fine mapping in the vicinity of the sex locus with SSR markers.By comparing the physical and genetic distances for the target interval encompassing the sex determination gene confined by SSRs,severe recombination repression was revealed in the sex determination region in the female map.The recombination rate in the confined interval encompassing the sex locus was approximately eight-fold lower than the genome-wide average.This study provides critical information relevant to sex determination in S.triandra. | Wei Li Huaitong Wu Xiaoping Li Yingnan Chen Tongming Yin | 2020 | Horticulture Research2020,7,1: | 3 |
