| 1 | Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases. | Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao | 2020 | Bone Research2020，8，1： | 8 |
| 2 | Earth Observation Brain(EOB):an intelligent earth observation system显示文摘Since the twenty-first century,with the rapid development of high-resolution earth observation satellites,the earth observation satellite system has developed from the initial single satellite observation model to the current satellite constellation formed by light and small satellites observation model.All-weather and all-directional fine earth observation can now be realized.In the future,the satellite constellation,communication satellites,navigation satellites,and aircrafts are linked through dynamic linking network to form an air-space information network to realize real-time services of intelligent air-space information.To further enhance the perception,cognition,and quick response ability of the network,we propose the concept and model of the Earth Observation Brain(EOB)−the intelligent earth system based on events perception in this paper.Then,some key technologies needed to be solved in the EOB are also described.An application example is illustrated to show the process of perception and cognition in the primary stage of the EOB.In the future,EOB can observe what change of what object,the when and where to push these right information to mobile terminal of right people at the right time and right place.Global users can obtain any data,information,and knowledge in real-time through the EOB. | Deren Li Mi Wang Zhipeng Dong Xin Shen Lite Shi | 2017 | Geo-Spatial Information Science2017，20，2： | 6 |

| 4 | Auricular vagus nerve acupressure for patients with emotional distress under the COVID-19 pandemic:A smartphone-based,randomized controlled trial显示文摘Objective: To confirm whether self-administered AVNA treatment is effective in improving emotional distressunder the COVID-19 pandemic.Methods: A smartphone-based online, randomized, controlled trial was designed from 26 February 2020 to 28April 2020 in four study sites, including Wuhan, Beijing, Shenyang, and Guangzhou of China. Local residentswho had considerable emotional distress with a score of the Hospital Anxiety and Depression Scale (HADS) ≥9 were recruited. Participants were randomly assigned to three times of AVNA (n = 191) per day, in morning,around noon, and in evening or usual care (UC, n = 215) once daily for 14 days. The primary outcome was theresponse rate, which was the proportion of participants whose Hospital Anxiety and Depression Scale (HADS)score reduced from baseline by ≥ 50%. The assessment was conducted at baseline, 3 days, and 14 days.Results: The AVNA group had a markedly higher response rate than the UC group at 3 days (35.6% vs. 24.9%,P = 0.02) and at 14 days (70.7% vs. 60.6%, P = 0.02). The AVNA group showed significantly greater reductionin scores of HADS at the two measurement points and BAI at 3 days (P ≤ 0.03), with average respective effectsize of 0.217 and 0.195. Participants with AVNA spent less time falling asleep and rated their sleep qualitybeing remarkably higher than those with UC at endpoint.Conclusion: During COVID-19 pandemic period, treatment with self-administrated AVNA was more effectivethan UC in reducing emotional distress of isolated populations. These findings support self-administered AVNAas a treatment option for patients with emotional distress under the COVID-19 pandemic or other emergentevents. | Peijing Rong Lei Wang Lingling Yu Junying Wang Yan Ma Liting Wang Suxia Li Chunzhi Tang Liming Lu Liang Li Jiazi Dong Jiliang Fang Liwei Hou Zongshi Qin Xiaolan Su Zhangjin Zhang | 2021 | TMR Modern Herbal Medicine2021，4，2： | 1 |
| 5 | Identification 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 | 2023 | Virologica Sinica2023，38，2： | 0 |
| 6 | Constructing metal-free heterophotocatalyst using two-dimensional carbon nitride sheets and violet phosphorene for highly efficient visible-light photocatalysis显示文摘Two-dimensional(2D)carbon nitride sheets(CNs)with nanoscale thickness have great potential in solar energy conversion owing to their intrinsic bandgap.However,their photocatalytic efficiency falls far below the practical requirements because the generated electron-hole pairs rapidly recombine.We construct a metal-free 2D p–n junction heterophotocatalyst from CNs and violet phosphorene(VP)using a simple electrostatic self-assembly method.The experimental results and density functional theory calculations show that the built-in electric field of the p–n junction promotes photogenerated carrier transport at the heterojunction interface,thereby promoting the separation of photogenerated electron-hole pairs.Under visible-light illumination,the visible-light photocatalytic hydrogen and CO production rates of the CNs/VP heterojunction were increased by 5.85 and 1.51 times,respectively,when compared to that of CNs.This study provides new insights into the design of metal-free heterogeneous photocatalysts with high catalytic activity。 | Yong Wang Chengxin Zeng Liting Wu Yalin Dong Yu Zhang Dingyi Yang Wen Hu Jian Hao Hongzhe Pan Rusen Yang | 2023 | Journal of Materials Science & Technology2023，，15： | 0 |
| 7 | SARS-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 | 2023 | Signal Transduction and Targeted Therapy2023，8，11： | 0 |

| 9 | Development of robust perovskite single crystal radiation detectors with high spectral resolution through synergetic trap deactivation and self-healing显示文摘Organic-inorganic halide perovskite single crystals(SCs)are promising materials for detecting ionizing radiation owing to their outstanding photoelectric conversion capability and inexpensive solution processability.However,the accuracy and stability of the detectors have been limited due to the charge traps and defects in SCs,especially when operated under high-precision photon-counting mode for energy spectrum acquisition.Here,we proposed a trap freezing deactivation route,which obviously suppressed dark current and noise by up to 97%and 92%,respectively.Furthermore,the bulk ion migration effect was essential for the ability to instantly self-heal defects induced by radiation damage at temperatures down to30C.Consequently,the detector exhibits a record high energy resolution of 7.5%at 59.5 keV for 241Amγ-ray source,which is the best solution-processed semiconductor radiation detectors at the same energy range.In addition,the detector maintains over 90%of its initial performance after 9 months of storage when tested in the air.Our results will represent a revision of the paradigm that high-spectral-resolution and robust radiation detectors can only be realized with high temperature grown inorganic semiconductor single crystals. | Lixiang Wang Yilong Song Liqi Li Liting Tao Minxing Yan Weihui Bi Xueying Yang Yuan Sun Qingfeng Dong Deren Yang Yanjun Fang | 2023 | InfoMat2023，5，9： | 0 |
| 10 | Isolation 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 | 2024 | Virologica Sinica2024，39，1： | 0 |
