2Oxidative stress in granulosa cells contributes to poor oocytequality and IVF-ET outcomes in women with polycystic ovarysyndrome显示文摘The increased levels of intraceHular reactive oxygen species (ROS) in granulosa cells (GCs) may allectthe pregnancy results in women with polycystic ovary syndrome (PCOS). In this study, we compared the in vitrofertilization and embryo transfer (IVF-ET) results of 22 patients with PCOS and 25 patients with tubal factorinfertility and detected the ROS levels in the GCs of these two groups. Results showed that the PCOS group hadsignificantly larger follicles on the administration day for human chorionic gonadotropin than the tubal factorgroup (P 〈 0.05); however, the number of retrieved oocytes was not significantly different between the two groups(P 〉 0.05). PCOS group had slightly lower fertilization, cleavage, grade IflI embryo, clinical pregnancy, andimplantation rates and higher miscarriage rate than the tubal factor group (P 〉 0.05). We further found asignificantly higher ROS level of GCs in the PCOS group than in the tubal factor group (P 〈 0.05). The increasedROS levels in GCs caused GC apoptosis, whereas NADPH oxidase 2 (NOX2) specific inhibitors (diphenyleneio-donium and apocynin) significantly reduced the ROS production in the PCOS group. In conclusion, the increasedROS expression levels in PCOS GCs greatly induced cell apoptosis, which further affected the oocyte quality andreduced the positive IVF-ET pregnancy results of women with PCOS. NADPH oxidase pathway may be involvedin the mechanism of ROS production in GCs of women with PCOS.Qiaohong Lai Wenpei Xiang Qing Li Hanwang Zhang Yufeng Li Guijin Zhu Chengliang Xiong Lei Jin 2018Frontiers of Medicine2018,12,5:26
3NiSe_(2)/Ni(OH)_(2) Heterojunction Composite through Epitaxial-like Strategy as High-Rate Battery-Type Electrode Material显示文摘Constructing heterojunction is a promising way to improve the charge transfer efficiency and can thus promote the electrochemical properties.Herein,a facile and effective epitaxial-like growth strategy is applied to NiSe2 nano-octahe-dra to fabricate the NiSe2-(100)/Ni(OH)2-(110)heterojunction.The heterojunction composite and Ni(OH)2(performing high electrochemical activity)is ideal high-rate battery-type supercapacitor electrode.The NiSe2/Ni(OH)2 electrode exhibits a high specific capacity of 909 C g^-1 at 1 A g^-1 and 597 C g^-1 at 20 A g^-1.The assembled asymmetric supercapacitor composed of the NiSe2/Ni(OH)2 cathode and p-phenylenediamine-functional reduced graphene oxide anode achieves an ultrahigh specific capacity of 303 C g^-1 at 1 A g^-1 and a superior energy density of 76.1 Wh kg^-1 at 906 W kg^-1,as well as an outstanding cycling stability of 82%retention for 8000 cycles at 10 A g^-1.To the best of our knowledge,this is the first example of NiSe2/Ni(OH)2 heterojunction exhibiting such remarkable supercapacitor performance.This work not only provides a promising candidate for next-generation energy storage device but also offers a possible universal strategy to fabricate metal selenides/metal hydroxides heterojunctions.Hao Mei Zhaodi Huang Ben Xu Zhenyu Xiao Yingjie Mei Haobing Zhang Shiyu Zhang Dacheng Li Wenpei Kang Dao Feng Sun 2020Nano-Micro Letters2020,12,5:3

6Structures and electronic properties of domain walls in Bi FeO3 thin films显示文摘Domain walls(DWs)in ferroelectrics are atomically sharp and can be created;erased,and reconfigured within the same physical volume of ferroelectric matrix by external electric fields.They possess a myriad of novel properties and functionalities that are absent in the bulk of the domains,and thus could become an essential element in next-generation nanodevices based on ferroelectrics.The knowledge about the structure and properties of ferroelectric DWs not only advances the fundamental understanding of ferroelectrics,but also provides guidance for the design of ferroelectric-based devices.In this article,we provide a review of structures and properties of DWs in one of the most widely studied ferroelectric systems,BiFeO3 thin films.We correlate their conductivity and photovoltaic properties to the atomic-scale structure and dynamic behaviors of DWs.Huaixun Huyan Linze Li Christopher Addiego Wenpei Gao Xiaoqing Pan 2019National Science Review2019,6,4:1

11Identification of broad neutralizing antibodies against Omicron subvariants from COVID-19 convalescents and vaccine recipients显示文摘Dear Editor,Omicron(B.1.1.529)was designated a variant of concern(VOC)on November 26,2021(Callaway,2021),and its subvariants BA.1,BA.2,and BA.3 emerged and circulated almost simultaneously(Desingu et al.,2022).BA.2 was more efficient in transmission and quickly overtook BA.1 to become the variant most frequently detected worldwide(Yamasoba et al.,2022a).Compared to the prototype SARS-CoV-2 spike protein(S),the BA.1 and BA.2 spike proteins harbor more than 30 mutations,of which 21 are identical between the two subvariants,while the BA.3 spike differs from BA.1 and BA.2 by 3 mutations in the receptor binding domain(RBD)(Fig.1A).More recently,BA.4 and BA.5(hereafter BA.4/5)emerged,sharing the same spike sequence and containing four additional mutations,Del69–70,L452R,F486V,and R493Q,compared with BA.2.BA.4/5 were detected first in South Africa and evolved independently of BA.2;they have spread widely and replaced BA.2 as the predominant VOC(Gruell et al.,2022b;Tegally et al.,2022).In addition,BA.2.75,derived from the BA.2 subvariant,harbors nine additional mutations in the spike protein compared with BA.2(Fig.1A).BA.4/5 and BA.2.75 have led to the continuous emergence of novel Omicron subvariants,including BF.7 and BQ.1.These new subvariants may be driving waves of pandemics.Jun Chen Jing Yang Fangfang Chang Yabin Hu Qian Wu Shishan Teng Yongchen Liu Jian Zhang Rongzhang He Bo Liu Xingyu Zheng Ze Liu Yanxi Peng Zhenhua Xie Yuanfang Zhang Rui Lu Dong Pan You Wang Liting Peng Wenpei Liu Yi-Ping Li Xiaowang Qu 2023Virologica Sinica2023,38,2:0
12SARS-CoV-2 spike-specific TFH cells exhibit unique responses in infected and vaccinated individuals显示文摘Long-term humoral immunity to SARS-CoV-2 is essential for preventing reinfection. The production of neutralizing antibody (nAb)and B cell differentiation are tightly regulated by T follicular help (T_(FH)) cells. However, the longevity and functional role of T_(FH) cellsubsets in COVID-19 convalescents and vaccine recipients remain poorly defined. Here, we show that SARS-CoV-2 infection andinactivated vaccine elicited both spike-specific CXCR3^(+) T_(FH) cell and CXCR3^(-) T_(FH) cell responses, which showed distinct responsepatterns. Spike- specific CXCR3^(+) T_(FH) cells exhibit a dominant and more durable response than CXCR3^(-) T_(FH) cells that positivelycorrelated with antibody responses. A third booster dose preferentially expands the spike-specific CXCR3^(+) T_(FH) cell subset inducedby two doses of inactivated vaccine, contributing to antibody maturation and potency. Functionally, spike-specific CXCR3^(+) T_(FH) cellshave a greater ability to induce spike-specific antibody secreting cells (ASCs) differentiation compared to spike-specific CXCR3^(-) T_(FH)cells. In conclusion, the persistent and functional role of spike-specific CXCR3^(+) T_(FH) cells following SARS-CoV-2 infection andvaccination may play an important role in antibody maintenance and recall response, thereby conferring long-term protection. Thefindings from this study will inform the development of SARS-CoV-2 vaccines aiming to induce long-term protective immunememory.Rongzhang He Xingyu Zheng Jian Zhang Bo Liu Qijie Wang Qian Wu Ziyan Liur Fangfang Chang Yabin Hu Ting Xie Yongchen Liu Jun Chen Jing Yang Shishan Teng Rui Lu Dong Pan You Wang Liting Peng Weijin Huang Velislava Terzieva Wenpei Liu Youchun Wang Yi-Ping Li Xiaowang Qu 2023Signal Transduction and Targeted Therapy2023,8,11:0
13Study on Subjects of Basic Medical Insurance in Urban Areas of China显示文摘The legal relationship of medical insurance refers to relationship of rights and obligations among subjects of medical insurance,namely relationship of rights and obligations formed among the insurer,the applicant, the insured and the beneficiary of medical insurance due to payment of medical insurance premiums and management and supervision of medical insurance fund.Only if the range of the insured serving as the subject of rights in such legal relationship,namely the insurant enjoying basic medical insurance,is defined can the legal relationship of basic medical insurance be better adapted to and values and goals of legal system of basic medical insurance be realized.Li Wenpei Lecturer of Law Department, China Institute of Industrial Relations 2010China's Foreign Trade2010,,2:0
14Superior multiphase interfaces in AgCuTe-based composite with significantly enhanced thermoelectric properties显示文摘It is common sense that a phase interface(or grain boundary)could be used to scatter phonons in thermoelectric(TE)materials,resulting in low thermal conductivity(k).However,a large number of impurity phases are always so harmful to the transport of carriers that poor TE performance is obtained.Here,we demonstrate that numerous superior multiphase(AgCuTe,Ag_(−2)Te,copper telluride(Cu_(2)Te and Cu_(2−x)Te),and nickel telluride(NiTe))interfaces with simultaneous strong phonon scattering and weak electron scattering could be realized in AgCuTe-based TE materials.Owing to the similar chemical bonds in these phases,the depletion region at phase interfaces,which acts as carrier scattering centers,could be ignored.Therefore,the power factor(PF)is obviously enhanced from~609 to~832μW·m^(−1)·K^(−2),and k is simultaneously decreased from~0.52 to~0.43 W·m^(−1)·K^(−1) at 636 K.Finally,a peak figure of merit(zT)of~1.23 at 636 K and an average zT(zTavg)of~1.12 in the temperature range of 523–623 K are achieved,which are one of the best values among the AgCuTe-based TE materials.This study could provide new guidance to enhance the performance by designing superior multiphase interfaces in the TE materials.Wenpei Li Zhonghai Yu Chengyan Liu Ying Peng Baoquan Feng Jie Gao Guojing Wu Xiaobo Bai Junliang Chen Xiaoyang Wang Lei Miao 2023Journal of Advanced Ceramics2023,12,8:0
15Feel Pressure Under China's Anti-monopoly Law?显示文摘After 14 years of debate,the legislature passed the Anti-monopoly Law(AML) at last on August 30,2007,which was informally referred to as the'economic constitution'.It came into effect only a few months after the equally significant Chinese Contract Law which spelled out specific and comprehensive rights for employees in China for the first time.Like the Contract Law,the Anti-Monopoly Law was problematic after itLuo Kaitian Li Wenpei 2009China's Foreign Trade2009,,15:0
16Geostructures, dynamics and risk mitigation of high-altitude and long- runout rockslides显示文摘Long-runout rockslides at high altitude could cause disaster chain in river basins and destroy towns and major infrasturctures.This paper firstly explores the initiation mechanism of high-altitude and long-runout rockslides.Two types of sliding-prone geostructure models,i.e.the fault control type in orogenic belt and the fold control type in platform area,are proposed.Then,large-scale experimental apparatus and associated numerical simulations are conducted to understanding the chain-style dynamics of rockslide-debris avalanche-debris flow.The results reveal the fragmentation effects,the rheological behaviors and the boundary layer effect of long-runout avalanche-debris flow.The dynamic character-istics of quasi-static-transition-inertia state and solid-liquid coupling in rapid movement of rockslide-debris avalanche-debris flow are investigated.Finally,the risk mitigation strategy of the non-structure and structure for resilient energy dissipation are illustrated for initiation,transition and deposition zones.The structural prevention and mitigation methods have been successfully applied to the high-altitude and long-runout rockslides in Zhouqu and Maoxian of the Wenchuan earthquake zone,as well as the other major geohazards in Qinghai-Tibet Plateau and its adjacent areas.Yueping Yin Bin Li Yang Gao Wenpei Wang Shilin Zhang Nan Zhang 2023Journal of Rock Mechanics and Geotechnical Engineering2023,15,1:0
17Isolation and characterization of spike S2-specific monoclonal antibodies with reactivity to pan-coronaviruses显示文摘Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),theseventh coronavirus known to jump from intermediate hosts to humans,has resulted in a worldwide pandemic and caused immense economicdamage(Tan et al.,2020;Zhu et al.,2020).It is believed that coronavirus spillover may occur again in the future.Human exposure to a bat coro-navirus has been serologically confimed in a rural area of China,indi-cating that the coronavirus spillover occurred,although the origin andfrequency of spillovers are unclear(Wang et al.,2018).Yabin Hu Jun Chen Jing Yang Zhanpeng Liu Xiaoyue Zhang Qian Wu Lulu Liu Shishan Teng Rongzhang He Bo Liu Xingyu Zheng Rui Lu Dong Pan You Wang Liting Peng Hongying chen Yi-Ping Li Wenpei Liu Xiaowang Qu 2024Virologica Sinica2024,39,1:0
