| 1 | Effect of maternal age on the outcomes of in vitro fertilization and embryo transfer(IVF-ET)显示文摘This is a retrospective,observational study to evaluate the effect of maternal age on the outcomes of in vitro fertilization and embryo transfer(IVF-ET).11830 IVF-ET cycles from 10268 women were included.Four groups of different maternal age periods were compared.The groups were 21 30 years old group(4549 cycles),31-35 years old group(4424 cycles),36-40 years old group(2429 cycles),and over 40 years old group(428 cycles).The mean starting dose of Gn and mean total dose of Gn in each cycle were significantly higher(P<0.01),while the mean retrieved oocyte number was significantly lower(P<0.01) in groups of higher maternal age period than those in each of the lower groups.The biochemical pregnancy rate and the clinical pregnancy rate were significantly lower(P<0.01),while the miscarriage rate was significantly higher(P<0.01) in groups of higher maternal age period than those in the lower groups.No difference was found in two-pronuclear zygotes(2PN) rate and good quality embryo rate among different groups.Birth defect rate was also comparable in the born babies in different groups.In the group with patients' age over 40 years old,the pregnancy rate was 26.87%,the clinical pregnancy rate was 19.39%,while the miscarriage rate after clinical pregnancy was 36.14%.To draw the conclusion,patients with higher maternal age had worse IVF outcomes.In women of fertile age,patients between 20 and 30 years old have the best IVF outcomes.Patients over 40 years old have poor IVF outcome and high miscarriage rate,which suggested the necessity of preimplantation genetic screening(PGS). | YAN JunHao WU KeLiang TANG Rong DING LingLing CHEN Zi-Jiang | 2012 | Science China(Life Sciences)2012，55，8： | 23 |

| 4 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015，58，9： | 12 |

| 6 | Characteristics of pantograph‐catenary arc under low air pressure and strong airflow显示文摘Pantograph‐catenary arc fault is the primary factor threatening the stability of the power transmission for high‐speed railway.The motion characteristics of the pantograph‐catenary arc under low air pressure and strong airflow is significantly different from the case under atmospheric pressure.In this paper,an experimental platform of panto-graph‐catenary arc was built to investigate arc root position‐time and arc column lon-gitudinal drift height‐time characteristic curves under different air pressures and airflow velocites.Via analysing the corresponding results,it can be found that there are different arc root-arc column traction mechanisms at different stages of arc development.The arcing time and arc root stagnation time under low air pressure are significantly longer than the case under atmospheric pressure,resulting in more serious electrode ablation.The arc column longitudinal drift velocity and height are greater with the increase of airflow velocity.Two typical irregular arc motion phenomena-arc root jumping and arc reignition are observed.To clarify the internal mechanism of the above phenomenon,a magnetohydrodynamics(MHD)model of the pantograph‐catenary arc was lauched,the influence mechanism of the pantograph‐catenary arc temperature and voltage are studied,and the physical process of arc temperature oscillation is analysed.The research results provide theoretical support for arc protection in high‐altitude areas. | Zhilei Xu Guoqiang Gao Wenfu Wei Zefeng Yang Wenhan Xie Keliang Dong Yaguang Ma Yan Yang Guangning Wu | 2022 | High Voltage2022，7，2： | 7 |
| 7 | Pantograph-catenary electrical contact system of high-speed railways:recent progress,challenges,and outlooks显示文摘As the unique power entrance,the pantograph-catenary electrical contact system maintains the efficiency and reliability of power transmission for the high-speed train.Along with the fast development of high-speed railways all over the world,some commercialized lines are built for covering the remote places under harsh environment,especially in China;these environmental elements including wind,sand,rain,thunder,ice and snow need to be considered during the design of the pantograph-catenary system.The pantograph-catenary system includes the pantograph,the contact wire and the interface—pantograph slide.As the key component,this pantograph slide plays a critical role in reliable power transmission under dynamic condition.The fundamental material characteristics of the pantograph slide and contact wire such as electrical conductivity,impact resistance,wear resistance,etc.,directly determine the sliding electrical contact performance of the pantograph-catenary system;meanwhile,different detection methods of the pantograph-catenary system are crucial for the reliability of service and maintenance.In addition,the challenges brought from extreme operational conditions are discussed,taking the Sichuan-Tibet Railway currently under construction as a special example with the high-altitude climate.The outlook for developing the ultra-high-speed train equipped with the novel pantograph-catenary system which can address the harsher operational environment is also involved.This paper has provided a comprehensive review of the high-speed railway pantograph-catenary systems,including its progress,challenges,outlooks in the history and future. | Guangning Wu Keliang Dong Zhilei Xu Song Xiao Wenfu Wei Huan Chen Jie Li Zhanglin Huang Jingwei Li Guoqiang Gao Guozheng Kang Chuanjun Tu Xingyi Huang | 2022 | Railway Engineering Science2022，30，4： | 5 |
| 8 | Dominant mutations in CHK1 cause pronuclear fusion failure and zygote arrest that can be rescued by CHK1 inhibitor显示文摘Dear Editor,Infertility poses a major challenge to human reproductive health,affecting approximately 48 million women worldwide.1 Assisted reproductive techniques(ART),including in vitro fertilization(IVF)and intracytoplasmic sperm injection(ICSI),enable infertile women to have their biological embryos in vitro and further give birth to babies after embryo transfer.However,about 10%of all human embryos produced by ART are blocked in the early embryonic stage2 and approximately 2%fertilized oocytes derived from ART could not accomplish the first cell division.3 About one half of human infertility cases involve an underlying genetic factor,although the majority of genetic causes have remained elusive.4 In this study,we report that dominant mutations in CHK1 are responsible for pronuclear fusion failure and zygote arrest(PFF-ZA)in 7 out of 29 cases,likely through increasing the CHK1 activity.Importantly,PFF-ZA caused by these mutations could be effectively rescued by using the CHK1 inhibitor,PF477736. | Honghui Zhang Tailai Chen Keliang Wu Zhenzhen Hou Shigang Zhao Chuanxin Zhang Yuan Gao Ming Gao Zi-Jiang Chen Han Zhao | 2021 | Cell Research2021，31，7： | 4 |
| 9 | Microbiome and ileum transcriptome revealed the boosting effects of selenium yeast on egg production in aged laying hens显示文摘The declines in laying performance during the late productionperiod have adverse effects on the length of theproduction cycle. Improving the nutrition of laying hens is a crucialmeasure to reverse this declination. Thisstudy investigatedthe effect of seleniumyeast (SY)on egg production, ileal gene expressionandmicrobiota, aswell as elucidating their associations in aged laying hens. A total of 375 Jinghong laying hens at 76weeks oldwere randomly assigned into 5 dietary treatments, which included a selenium-deficient basal diet based oncorn-soybean meal, and dietary supplementation of SY at 0.15, 0.30 and 0.45 mg/kg, and sodium selenite at0.45mg/kg.The results showed that SYamelioratedthe depressionin aged layingperformance inthe 0.30mg/kg group (P < 0.01). Selenium yeast significantly increased ileum selenium concentration (P < 0.05), and SYgroups had higher seleniumdeposition efficiency than the sodiumselenite group. Functional enrichment andShort Time-series Expression Miner (STEM) analysis indicated that SY activated metabolic progress (e.g.,glycerolipidmetabolism, glycerophospholipidmetabolism, andfattyacidmetabolism),immune responseandoxidative stress response. Four hub genes including thioredoxin reductase 1 (TXNRD1), dihydrolipoamidedehydrogenase (DLD), integrin linked kinase (ILK) and leucine zipper tumor suppressor 2 (LZTS2) wereinvolved in intestinal metabolismwhich was closely associated with selenium deposition/status. Moreover,the relative abundance of Veillonella, Turicibacter and Lactobacillus was significantly increased, but the relativeabundance of Stenotrophomonas was significantly decreased by SY supplementation. Multi-omics dataintegration and Canonical correspondence analysis (CCA) showed that both the ileumselenium content andthe laying rate were highly correlated with pathways and bacteria enriched in metabolism and immuneresponse. Meanwhile, the “switched on” gene prostate stem cell antigen (PSCA) had a positive relationshipwith Veillonella and a negative relationship with the opportunistic pathogens Stenotrophomonas. Overall, ourstudy offered insight for the further exploration of the role of SY on boosting egg production and balancingileum intestinal flora in aged laying hens. | Zhexi Liu Yutao Cao Yue Ai Xiaonan Yin Linli Wang Mengyao Wang Bingkun Zhang Zhengxing Lian Keliang Wu Yuming Guo Hongbing Han | 2022 | Animal Nutrition2022，，3： | 3 |
| 10 | In vitro expansion of human sperm through nuclear transfer显示文摘Dear Editor,Mammalian haploid embryonic stem cells(haESCs)represent an ideal tool for genetic analysis due to the presence of only one set of genetic materials.HaESCs fall into two readily distinguishable groups based on their genome origins:parthenogenetic haESCs(PG-haESCs)that are derived from oocyte-originated parthenogenetic embryos and androgenetic haESCs(AG-haESCs)that are produced through sperm nuclear transfer.Both PG-and AGhaESCs are feasible for delineating genome function at cellular level in vitro.Importantly,AG-haESCs can be used as a sperm replacement and applied to deciphering gene function at organismal level when combined with CRISPR-Cas9 technology.1 However,while PG-haESCs have been generated from both rodent and primates,2-5 AG-haESCs can only be obtained in rodent to date. | Xiaoyu Merlin Zhang Keliang Wu Yuxuan Zheng Han Zhao Junpeng Gao Zhenzhen Hou Meiling Zhang Jiaoyang Liao Jingye Zhang Yuan Gao Yuanyuan Li Lin Li Fuchou Tang Zi-Jiang Chen Jinsong Li | 2020 | Cell Research2020，30，4： | 3 |
| 11 | Rhodojaponin Ⅵ indirectly targets Cav2.2 channels via N-ethylmaleimide-sensitive fusion protein to alleviate neuropathic pain显示文摘Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients,but currently available treatments are often ineffective.Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed.Rhodojaponin Ⅵ,a grayanotoxin from Rhododendron molle,showed remarkable antinociceptive efficacy in models of neuropathic pain,but its biotargets and mechanisms are unknown.Given the reversible action of rhodojaponin Ⅵ and the narrow range over which its structure can be modified,we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin Ⅵ.N-Ethylmaleimide-sensitive fusion(NSF) was confirmed as the key target of rhodojaponin Ⅵ through biological and biophysical experiments.Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca2+current intensity,whereas rhodojaponin Ⅵ reversed the effects of NSF.In conclusion,rhodojaponin Ⅵ represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF. | Keliang Chen Tao Wang Yong Li Jun Wu Cheng-Xiao Zhao Sheng Liu Fengrun Sun Yehong Fang Jiahuan Hu Jinping Hu Chong-Jing Zhang Haibo Yu Chao Ma Shi-Shan Yu | 2023 | Acta Pharmaceutica Sinica B2023，13，3： | 2 |

| 13 | Effects of pituitary-specific overexpression of FSHα/β on reproductive traits in transgenic boars显示文摘Background: Follicle-stimulating hormone(FSH) is a gonadotropin synthesized and secreted by the pituitary gland.FSH stimulates follicle development and maturation in females. It also plays an important role in spermatogenesis in males, including humans and mice. However, the effects of FSH on male pigs are largely unknown. In this study,we generated transgenic pigs to investigate the effects of FSHα/β overexpression on reproductive traits in boars.Results: After five transgenic F_0 founders were crossed with wide-type pigs, 193 F_1 animals were obtained. Of these,96 were confirmed as transgenic. FSHα and FSHβ m RNAs were detected only in pituitary tissue. Transgenic boars exhibited significantly higher levels of FSHα and FSHβ m RNA, serum FSH, and serum testosterone, compared to ful-sib non-transgenic boars. Significant increases in testis weight, vas deferens diameter, seminiferous tubule diameter,and the number of Leydig cel s were observed, suggesting that the exogenous FSHα/β affects reproductive traits. Final y,transgenic and non-transgenic boars had similar growth performance and biochemical profiles.Conclusions: Pituitary-specific overexpression of FSHα/β genes is likely to impact reproductive traits positively, as indicated by enhancements in serum testosterone level, testis weight, the development of vas deferens, seminiferous tubules, and Leydig cells in transgenic boars. A high level of serum FSH induces secretion of serum testosterone,possibly by boosting the number of Leydig cells, which presumably increases the libido and the frequency of sexual activity in transgenic boars. Our study provides a preliminary foundation for the genetic improvement of reproductive traits in male pigs. | Wenting Li Yujun Quan Mengmeng Zhang Kejun Wang Muzhen Zhu Ye Chen Qiuyan Li Keliang Wu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 1 |

| 17 | Eu(III) adsorption on rutile:Batch experiments and modeling显示文摘Eu(III) adsorption on rutile was investigated as a function of contact time,pH,ionic strength and Eu(III) concentration by using a batch experimental method.The effects of carbonate,sulfate,and phosphate were also studied.It was found that the kinetics of Eu(III) adsorption on rutile could be described by a pseudo-second-order model.The adsorption of Eu(III) on rutile is strongly pH-dependent,but relatively insensitive to ionic strength.A double layer model (DLM) with two inner-sphere Eu(III) surface complexes was applied to quantitatively interpret the adsorption of Eu(III) on rutile.There were no apparent effects of carbonate and sulfate on Eu(III) adsorption,whereas the presence of phosphate promoted Eu(III) adsorption on rutile.The surface complexes of Eu(III) on rutile were evidenced by X-ray photoelectron spectroscopy (XPS). | WANG XueFeng,SHI KeLiang,GUO ZhiJun & WU WangSuo Radiochemistry Lab,School of Nuclear Science and Technology,Lanzhou University,Lanzhou 730000,China | 2010 | Science China Chemistry2010，53，12： | 1 |
