| 1 | The altered PD-1/PD-L1 pathway delivers the ‘one-two punch’ effects to promote the Treg/Th17 imbalance in pre-eclampsia显示文摘The programmed cell death-1(PD-1)/PD-ligand 1(PD-L1)pathway is critical for normal pregnancy by promoting regulatory T(Treg)cell development and inhibiting the Th17 response.However,the relationship between the PD-1/PD-L1 pathway and the Treg/Th17 imbalance in pre-eclampsia(PE)is an enigma.In this study,decreased PD-1 and PD-L1 expression and a Treg/Th17 imbalance were observed at the maternal-fetal interface in PE.The regulatory effects of the PD-1/PD-L1 pathway on the Treg and Th17 cell quantities were determined in vitro by targeting T-cell proliferation,differentiation and transdifferentiation.First,decreased PD-1 expression might contribute to a higher Th17 cell frequency by promoting proliferation in PE.Second,the percentages of Treg but not Th17 cells differentiated from peripheral naive CD4+T cells were increased by PD-L1 Fc administration.This effect was accompanied by decreased PI3K/AKT/m-TOR and increased PTEN mRNA expression and was completely reversed by PD-1 blockade.Finally,the percentage of IL-17-producing Treg cells increased and was positively associated with the Th17 cell frequency in PE.Increased RORγt and IL-17 but not Foxp3 and IL-10 mRNA expression by Treg cells was observed with PD-1 blockade.Similar findings occurred when Treg cells were exposed to IL-6/IL-23/IL-1βand were reversed by PD-L1 Fc.Taken together,our findings indicate that the PD-1/PD-L1 pathway contributes to the Treg/Th17 imbalance via‘one-two punch’approaches:(i)promoting Th17 cell proliferation,(ii)inhibiting Treg cell differentiation and(iii)enhancing Treg cell plasticity into Th17 cells in PE.The therapeutic value of PD-L1 Fc for PE treatment will be explored in the future. | Yonghong Zhang Zhaozhao Liu Mei Tian Xiaohui Hu Liling Wang Jinlu Ji Aihua Liao | 2018 | Cellular & Molecular Immunology2018，15，7： | 21 |
| 2 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |

| 4 | Comparison of chicoric acid,and its metabolites caffeic acid and caftaric acid:In vitro protection of biological macromolecules and inflammatory responses in BV2 microglial cells显示文摘Chicoric acid(CA),a natural phenolic acid,has been used as a nutraceutical food ingredient due to its powerful antioxidant,anti-HIV and anti-diabetic bioactivities.CA could be partly metabolized into caffeic acid(CFA)and caftaric acid(CTA)on cytochrome P450s in rat liver microsomes.To compare the protective effects of CA and its metabolites on biomolecules and inflammatory responses,oxidative damage induced by free radicals in vitro and microglial inflammation triggered by lipopolysaccharide in BV2 cells were constructed.Results showed that CA,CTA and CFA all significantly inhibited protein degradation and carbonylation induced by hydroxyl radicals and alcoxyl radicals,and suppressed hemin/nitrite/H2O2 triggered-nitration.Moreover,CA,CTA and CFA all exerted remarkable inhibition capacities on linoleic acid and soybean lecithin liposomes peroxidation in a dose-dependent manner,and restrained the oxidation of herring sperm DNA,as well as the breakage of pBR322 plasmid DNA.Furthermore,CA and its metabolites suppressed lipopolysaccharide-induced decline of BV2 cell viability and the production of NO and ROS.However,bioactivities of CA were significantly stronger than those of its metabolites within a certain concentration range.This study provides scientific basis for the application of CA and its metabolites as nutrition and natural antioxidants. | Qian Liu Fan Liu Liling Zhang Yajie Niu Zhigang Liu Xuebo Liu | 2017 | Food Science and Human Wellness2017，6，4： | 5 |
| 5 | Aquaporin 5 is degraded by autophagy in diabetic submandibular gland显示文摘Autophagy is a catabolic process which is involved in the development of many diseases including diabetes mellitus and its complications. Hyposalivation is a common complication of diabetes mellitus, whereas its mechanism remains unclear. Here, we observed that the stimulated salivary flow rate of SMG was significantly decreased in db/db mice, a diabetic mice model. The expressions of aquaporin 5(AQP5), a water channel protein, were decreased, whereas the m RNA level of AQP5 was increased in SMGs of both diabetic patients and mice. Under transmission electron microcope, more autophagosomes were detected in diabetic SMGs. Expressions of autophagy related proteins LC3 II, Beclin-1 and ATG5 were increased, meanwhile autophagy substrate p62 was decreased in SMGs of diabetic patients and mice, indicating that autophagy was activated in diabetic SMG.Double immunofluorescence staining showed that the colocalization of AQP5 and LC3 was increased in SMGs of diabetic mice.In cultured SMG-C6 cells, high glucose(HG), but not high osmotic pressure, reduced AQP5 protein expression and induced autophagy. Moreover, inhibition of autophagy by 3-methyladenin, an autophagy inhibitor, or by autophagy-related gene 5 siRNA, decreased HG-induced AQP5 reduction in SMG-C6 cells. Additionally, the expression of p-p85, p-Akt and p-mTOR were decreased in HG-treated SMG-C6 cells. Pretreatment with 740 Y-P, a PI3 K agonist, significantly suppressed HG-induced autophagy and AQP5 degradation. Taken together, these results indicate that autophagy plays a crucial role in AQP5 degradation in diabetic SMG via PI3 K/Akt/mTOR signaling pathway, which contributes to the dysfunction of diabetic SMG. Our study provides a novel mechanism of diabetic hyposalivation. | Yan Huang Xijin Shi Qianying Mao Yan Zhang Xin Cong Xueming Zhang Zhejing Zhang Liling Wu Ruolan Xiang Guangyan Yu | 2018 | Science China(Life Sciences)2018，61，9： | 5 |
| 6 | Introduction of a multicenter online database for non-metastatic breast cancer in China显示文摘Dear Editor,Breast cancer is now the most frequently diagnosed cancer and is the fifth leading cause of cancer-related death in Chinese women. Therefore, the burden of breast cancer in China is gradually increasing. According to figures released by the Chinese Cancer Center in 2018, the number of newly diagnostic breast cancer is about 278,900 cases, accounting for 16.51%of all women who were diagnosed with the first primary malignant tumors;and 66,000 cases of breast cancer died in 2014 (Chen et al., 2016). | Yaping Yang Jieqiong Liu Min Peng Fengxi Su Xiaoming Xie Zhenzhen Liu Jundong Wu Wei Wei Dongxian Zhou Weiwen Li Ailing Zhang Guosen Su Weixiong Yang Jishang Chen Dekui Ma Yongguang Cai Kai Chen Liling Zhu Qiang Liu Erwei Song | 2020 | Science China(Life Sciences)2020，63，9： | 4 |
| 7 | In pursuit of a flawless aphrodite:paving the way to scarless oncoplastic breast surgery显示文摘Introduction Breast cancer is the most commonly diagnosed malig-nancy in women worldwide[1,2]and in the twentieth century,mastectomy was the primary surgical treatment for breast cancer patients.Advances in breast-conserving surgery(BCS)propelled a change in treatment rational from“maximum tolerable”to“minimum effective”ther-apy.Oncoplastic breast surgery aims to restore the shape of the breast and has been widely adopted since the past decade.Although the cosmetic outcome has been sig-nificantly improved,the scar remaining on the surgeried breast skin is still a major pitfall that urges urgent consid-eration.In this editorial,we review a series of techniques that can be incorporated in oncoplastic breast surgery to minimize scarring,signifying the beginning of an era for scarless oncoplastic surgery. | Liling Zhu Shunrong Li Luyuan Tan Xiaolan Zhang Jiannan Wu Fengxi Su Kai Chen Erwei Song | 2019 | Cancer Communications2019，39，1： | 4 |
| 8 | Effects of gravity on the microstructure of Zr_(41)Ti_(14)-Cu_(12.5)Ni_(10)Be_(22.5) bulk glass forming alloy显示文摘The ZrTiCuNiBe alloy is melt and solidified by Bridgman unidirectional solidification on two gravity field orientations (the gravity field orientation is parallel and opposite to solidification direction). Effects of gravity on morphology and microstructure are investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). When gravity field orientation is parallel to solidificationdirection, less needle-like primary phase is embedded in a matrix eutectic; when gravity field orientation is opposite to solidification direction, a large amount of coarser needle-like primary phases were observed. | LI Gong, ZHAN Zaiji, WANG Limin, CAO Limin, SUN Liling, DAI Daoyang, ZHANG Jun & WANG WenkuiInstitute of Physics, Center for Condensed Matter Physics, Chinese Academy of Sciences, Beijing 100080, China Department of Materials Science and Engineering, Yanshan University, Qinhuangdao 066004, China | 2001 | Chinese Science Bulletin2001，46，11： | 3 |
| 9 | Cu_2O nanowires as anode materials for Li-ion rechargeable batteries显示文摘Li-ion batteries are a key technology for multiple clean energy applications.In this study,Cu2O nanowires were obtained by the reduction of cupric acetate with pyrrole.The resulting Cu2O nanowires exhibited excellent reversible capacities of 470mAh g-1 at rate of 1 C after 100 cycles.The results show that the Cu2O nanowires had more capacity than materials previously reported.No fading was observed over 100 cycles of charging and discharging.The compound metal Cu and incorporation of the conducting polymer polypyrrole(PPy)improved the conductivity of Cu2O and enhanced the stability of the electrode during cycling.The results from this study imply that Cu2O nanowires with high capacity and good cycle retention could be excellent candidates as anode materials for Li-ion rechargeable batteries. | CHEN Rui WANG Ying NULI YanNa YU Yuan GAO PengFei CHEN Qiang WEI LiangMing HU NaTao YANG Zhi GAO RunGang ZHANG LiLing ZHANG YaFei | 2014 | Science China(Technological Sciences)2014，57，6： | 3 |
| 10 | Observation of a bi-critical point between antiferromagnetic and superconducting phases in pressurized single crystal Ca0.73La0.27FeAs2显示文摘One of the most strikingly universal features of the high-temperature superconductors is that the superconducting phase emerges in the close proximity of the antiferromagnetic phase, and the interplay between these two phases poses a long-standing challenge. It is commonly believed that, as the antiferromagnetic transition temperature is continuously suppressed to zero, there appears a quantum critical point, around which the existence of antiferromagnetic fluctuation is responsible for the development of the superconductivity. In contrast to this scenario, we report the observation of a bi-critical point identified at 2.88 GPa and 26.02 K in the pressurized high-quality single crystal Ca_(0.73)La_(0.27)FeAs_2 by complementary in-situ high pressure measurements. At the critical pressure, we find that the antiferromagnetism suddenly disappears and superconductivity simultaneously emerges at almost the same temperature, and that the external magnetic field suppresses the superconducting transition temperature but hardly affects the antiferromagnetic transition temperature. | Yazhou Zhou ShanJiang Qi wu Vladimir A.Sidorov Jing Guo Wei Yi Shan Zhang Zhe Wang HonghongWang shu Cai Ke Yang Sheng Jiang Aiguo Li Ni Ni Guangming Zhang Liling Sun Zhongxian Zhao | 2017 | Science Bulletin2017，62，12： | 3 |

| 12 | FRACTAL ANALYSES OF DIRECTIONAL SOLIDIFICATION BEHAVIOR OF A Ni-BASE SUPERALLOY显示文摘The morphology of solid/liquid interface of a directionally solidification process is describedby means of fractal analysis,and the relations among the fractal dimension of the solid/liq-uid interface,solidification rate,dendrite arm space and the phosphorus content of the test al-loys have been given.It was found that the increase of the solidification rate and the phos-phorus content of the test alloy will lead to a increase,following the regularity of exponentialfunction,in the fractal dimension of solid/liquid interface.Furthermore,by combining thefractal theory and the thermodynamic principle with the measured results,it has been provedthat the fractal dimension is not only a kind of simple geometrical parameter used in des-cribing irregular geometry,but also a state function depending the change of solidificationparameters and chemical compositions. | SUN Liling DONG Lianke ZHANG Jishan TANG Yajun ZHANG Jinghua HU Zhuangqi Institute of Metal Research,Academia Sinica,Shenyang,China SUN Liling,Institute of Metal Research,Academia Sinica,Shenyang 110015,China | 1993 | Acta Metallurgica Sinica(English Letters)1993，6，5： | 2 |
| 13 | Pandemic threat posed by H3N2 avian influenza virus显示文摘Dear Editor,In the last century,H1N1,H2N2,and H3N2 influenza viruses caused pandemics in 1918,1957,and 1968,respectively.In 2009,a novel H1N1 reassortant jumped from pigs to humans and caused a fourth influenza pandemic.Different lineages of H3N2 influenza viruses are commonly found in animal reservoirs.If a different lineage of H3N2 virus jumps to humans,another human influenza pandemic could occur with devastating consequences. | Yaping Zhang Conghui Zhao Yujie Hou Yan Chen Fei Meng Yichao Zhuang Liling Liu Yasuo Suzuki Jianzhong Shi Guohua Deng Hualan Chen | 2021 | Science China(Life Sciences)2021，64，11： | 2 |
| 14 | Construction of Dual-Biofunctionalized Chitosan/Collagen Scaffolds for Simultaneous Neovascularization and Nerve Regeneration显示文摘Biofunctionalization of artificial nerve implants by incorporation of specific bioactive factors has greatly enhanced the success of grafting procedures for peripheral nerve regeneration.However,most studies on novel biofunctionalized implants have emphasized the promotion of neuronal and axonal repair over vascularization,a process critical for long-term functional restoration.We constructed a dual-biofunctionalized chitosan/collagen composite scaffold with Ile-Lys-Val-Ala-Val(IKVAV)and vascular endothelial growth factor(VEGF)by combining solution blending,in situ lyophilization,and surface biomodification.Immobilization of VEGF and IKVAV on the scaffolds was confirmed both qualitatively by staining and quantitatively by ELISA.Various single-and dual-biofunctionalized scaffolds were compared for the promotion of endothelial cell(EC)and Schwann cell(SC)proliferation as well as the induction of angiogenic and neuroregeneration-associated genes by these cells in culture.The efficacy of these scaffolds for vascularization was evaluated by implantation in chicken embryos,while functional repair capacity in vivo was assessed in rats subjected to a 10mm sciatic nerve injury.Dual-biofunctionalized scaffolds supported robust EC and SC proliferation and upregulated the expression levels of multiple genes and proteins related to neuroregeneration and vascularization.Dual-biofunctionalized scaffolds demonstrated superior vascularization induction in embryos and greater promotion of vascularization,myelination,and functional recovery in rats.These findings support the clinical potential of VEGF/IKVAV dual-biofunctionalized chitosan/collagen composite scaffolds for facilitating peripheral nerve regeneration,making it an attractive candidate for repairing critical nerve defect.The study may provide a critical experimental and theoretical basis for the development and design of new artificial nerve implants with excellent biological performance. | Guicai Li Qi Han Panjian Lu Liling Zhang Yuezhou Zhang Shiyu Chen Ping Zhang Luzhong Zhang Wenguo Cui Hongkui Wang Hongbo Zhang | 2020 | Research2020，，1： | 2 |

| 20 | Continued evolution of the Eurasian avian-like H1N1 swine influenza viruses in China显示文摘Animal influenza viruses continue to pose a threat to human public health. The Eurasian avian-like H1N1(EA H1N1) viruses are widespread in pigs throughout Europe and China and have caused human infections in several countries, indicating their pandemic potential. To carefully monitor the evolution of the EA H1N1 viruses in nature, we collected nasal swabs from 103,110pigs in 22 provinces in China between October 2013 and December 2019, and isolated 855 EA H1N1 viruses. Genomic analysis of 319 representative viruses revealed that these EA H1N1 viruses formed eight different genotypes through reassortment with viruses of other lineages circulating in humans and pigs, and two of these genotypes(G4 and G5) were widely distributed in pigs.Animal studies indicated that some strains have become highly pathogenic in mice and highly transmissible in ferrets via respiratory droplets. Moreover, two-thirds of the EA H1N1 viruses reacted poorly with ferret serum antibodies induced by the currently used H1N1 human influenza vaccine, suggesting that existing immunity may not prevent the transmission of the EA H1N1 viruses in humans. Our study reveals the evolution and pandemic potential of EA H1N1 viruses and provides important insights for future pandemic preparedness. | Fei Meng Yan Chen Zuchen Song Qiu Zhong Yijie Zhang Chuanling Qiao Cheng Yan Huihui Kong Liling Liu Chengjun Li Huanliang Yang Hualan Chen | 2023 | Science China(Life Sciences)2023，66，2： | 1 |
