| 1 | Biallelic mutations in CDC20 cause female infertility characterized by abnormalities in oocyte maturation and early embryonic development显示文摘Dear Editor,Previously,the Mendelian phe no types in huma n oocyte maturation arrest,fertilization failure and early embryonic arrest,are largely underestimated.In recent years,'missing'Men delian phe no types and genes in these processes are beginning to be uncovered by us and others(Huang et al.,2014;Alazami et al..2015;Feng et al.,2016;Xu et al.,2016;Chen et al.,2017;Sang et al.,2019).However,the genetic basis for majority of patients resulting from abnormalities in these phe no types remains to be elucidated. | Lin Zhao Songguo Xue Zhongyuan Yao Juanzi Shi Biaobang Chen Ling Wu Lihua Sun Yao Xu Zheng Yan Bin Li Xiaoyan Mao Jing Fu Zhihua Zhang Jian Mu Wenjing Wang Jing Du Shuai Liu Jie Dong Weijie Wang Qiaoli Li Lin He Li Jin Xiaozhen Liang Yanping Kuang Xiaoxi Sun Lei Wang Qing Sang | 2020 | Protein & Cell2020，11，12： | 10 |
| 2 | Efficacy and safety of low-dose interleukin-2 in combination with methotrexate in patients with active rheumatoid arthritis:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Rheumatoid arthritis(RA)is an aggressive autoimmune arthritis,and current therapies remain unsatisfactory due to low remission rate and substantially adverse effects.Low-dose interleukin-2(Ld-IL2)is potentially a therapeutic approach to further improve the disease.This randomized,double-blind,placebo-controlled trial was undertaken to evaluate the efficacy and safety of Ld-IL2 in patients with active RA.Patients were randomly assigned(1:1)to receive Ld-IL2,defined as a dose of 1 million IU,or placebo in a 12-week trial with a 12-week follow-up.Three cycles of Ld-IL2 or placebo were administered subcutaneously every other day for 2 weeks(a total of 7 doses),followed by a 2-week break.All patients received a stable dose of methotrexate(MTX).The primary outcomes were the proportion of patients achieving the ACR20,DAS28-ESR<2.6,and the change from baseline in CDAI or SDAI at week 24.Secondary endpoints included other clinical responses and safety.The primary outcomes were achieved in the perprotocol population.The improvements from baseline in CDAI and SDAI were significantly greater across time points for the LdIL2+MTX group(n=17)than for the placebo+MTX group(n=23)(P=0.018 and P=0.015,respectively).More patients achieved ACR20 response in the Ld-IL2+MTX group than those in the placebo+MTX group at week 12(70.6%vs 43.5%)and at week 24(76.5%vs 56.5%)(P=0.014).In addition,low Treg and high IL-21 were associated with good responses to Ld-IL2.Ld-IL-2 treatment was well-tolerated in this study.These results suggested that Ld-IL2 was effective and safe in RA.ClinicalTrials.gov number:NCT 02467504. | Xiaoying Zhang Miao Miao Ruijun Zhang Xu Liu Xiaozhen Zhao Miao Shao Tian Liu Yuebo Jin Jiali Chen Huixin Liu Xia Zhang Yun Li Yunshan Zhou Yue Yang Ru Li Haihong Yao Yanying Liu Chun Li Yuhui Li Limin Ren Yin Su Xiaolin Sun Jing He Zhanguo Li | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 7 |
| 3 | Uncommon EGFR mutations in a cohort of Chinese NSCLC patients and outcomes of first-line EGFR-TKIs and platinum-based chemotherapy显示文摘Objective: Data on the clinical activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in patients with non-small-cell lung cancer(NSCLC) and uncommon EGFR mutations remain insufficient.This study aimed to investigate the effect of first-line EGFR-TKIs or platinum-based chemotherapy in NSCLC patients with uncommon EGFR mutations.Methods: We retrospectively enrolled 504 patients with EGFR-mutant NSCLC.The clinical characteristics and treatment outcomes were collected and compared between patients with common and uncommon EGFR-mutant NSCLC.Results: Seventy patients(13.9%) harboring uncommon EGFR mutations were included.Thirty of these patients received EGFR-TKIs and 40 received platinum-based chemotherapy as first-line therapy.The objective response rate(ORR) and median progression-free survival(m PFS) of patients treated with TKIs in the uncommon mutation group was significantly inferior to that in the common mutation group(ORR: 23.3% vs.51.8%,P=0.003; m PFS:7.1 vs.10.9 months,P<0.001).In the uncommon group,m PFS was similar between first-line EGFR-TKIs treatment and platinum-based chemotherapy(7.1 vs.6.1 months,P=0.893).In patients with EGFR G719 X or L861 Q mutations,the m PFS was longer in the first-line EGFR-TKIs treatment group than in the chemotherapy group,but the difference was not statistically significant(G719 X: 8.2 vs.5.8 months,P=0.061; L861 Q: 7.6 vs.4.1 months,P=0.872).Multivariate analyses identified adenocarcinoma(P=0.003) as the independent predictive factor for PFS in patients with uncommon EGFR mutations who were treated with first-line EGFR-TKIs.Conclusions: The current study demonstrated that the effect of first-line EGFR-TKIs was similar to that of platinum-based chemotherapy in patients with uncommon EGFR-mutant NSCLC.Adenocarcinoma was the independent predictive factor for PFS in uncommon EGFR-mutant NSCLC patients treated with first-line EGFRTKIs. | Jinpeng Shi Hui Yang Tao Jiang Xuefei Li Chao Zhao Limin Zhang Sha Zhao Xiaozhen Liu Yijun Jia Yan Wang Lei Xi Shijia Zhang Chunxia Su Shengxiang Ren Caicun Zhou | 2017 | Chinese Journal of Cancer Research2017，29，6： | 6 |
| 4 | Anatomy of the perirectal fascia at the level of rectosacral fascia revisited显示文摘Background:The relative anatomical understanding of the perirectal fasciae is of paramount importance for the proper performance of total mesorectal excision(TME).This study was to demonstrate the planes of TME and validates the intraoperative findings using cadaveric observations.Methods:In this combined retrospective and prospective study,bilateral attachment of the rectosacral fascia(RSF)was observed in 28 cadaveric specimens(male,n=14;female,n=14).From January 2018 to December 2019,surgical videos of 67 patients who underwent laparoscopic TME at the Affiliated Union Hospital of Fujian Medical University(Fuzhou,China)were reviewed and interpreted with the cadaveric findings.Results:The RSF(synonym:Waldeyer’s fascia)is the end of the pre-hypogastric fascia at the level of S4 and comprises two layers(upper and lower).These two layers provide double fascial protection for the venous sacral plexus.It inserts into the fascia propria of the rectum along a broad horizontal arc that merges anterolaterally in an oblique downward direction until it meets the posterolateral merge of Denonvilliers’fascia at the lateral rectal ligament(LRL).This ligament does not look like a true ligament but is more likely to be a fascial combination that cushions the rectal innervation and middle rectal vessels.Conclusions:Understanding the lateral attachment of RSF and its contribution to LRL provides invaluable surgical guidance to dissect this critical area.Therefore,lateral dissection is proposed from the anterior to the posterior direction to find the correct plane that guarantees an intact mesorectal envelope to protect the important nearby nerve structures. | Waleed M.Ghareeb Xiaojie Wang Pan Chi Zhifang Zheng Xiaozhen Zhao | 2022 | Gastroenterology Report2022，10，1： | 3 |

| 7 | Enhanced endosomal escape of dendrigraft poly-L-lysine polymers for the efficient gene therapy of breast cancer显示文摘Dendrimer,such as dendrigraft poly-L-lysine(DGL)polymers,with high surface charge density,well-defined structure,and narrow poly-dispersity is often employed as a gene vector,but its transfection efficiency is still partially inhibited due to poor endosomal escape ability.Herein,we used a surface modification strategy to enhance the endosomal escape ability of DGL polymers,and thus improved its gene transfection efficiency.A library of phenylboronic acid(PBA)modified DGL polymers(PBA-DGLs)was designed to screen efficient small interfering RNA(siRNA)vectors.The lead candidate screened from the library shown a capability of inducing nearly 90% gene silencing in MDA-MB-231 cells.The study of the transfection mechanism revealed that PBA modification not only improves siRNA cellular uptake,but,more importantly,endows DGL polymers the ability of endosomal escape.One of the top candidates from polyplexes was further shielded with hyaluronic acid to construct targeted nanoparticles,and the yielding nanoparticles significantly suppressed the tumor growth in a breast cancer model by effective siRNA delivery.This research provides a general and effective strategy to enhance the endosomal escape and transfection efficiency of dendrimer. | Li Ye Hongmei Liu Xin Fei Ding Ma Xiaozhen He Qianyun Tang Xue Zhao Hanbing Zou Xiaojing Chen Xianming Kong Peifeng Liu | 2022 | Nano Research2022，15，2： | 1 |

| 10 | The“terminal line”:a novel sign for the identification of distal mesorectum end during TME for rectal cancer显示文摘Background:Although the clinical importance of complete,intact total mesorectal excision(TME)is the widely accepted standard for decreasing local recurrence of rectal cancer,the residual mesorectum still represents a significant component of resection margin involvement.This study aimed to use a visible intraoperative sign to detect the distal mesorectal end to ensure complete inclusion of the mesorectum and avoid unnecessary over-dissection.Methods:The distal mesorectum end was investigated retrospectively through a review of 124 operative videos at the Union Hospital of Fujian Medical University(Fujian,China)and Cleveland Clinic(Ohio,USA)by two independent surgeons who were blinded to each other.Furthermore,28 cadavers and 44 post-operative specimens were prospectively examined by hematoxylin and eosin(H&E)staining and Masson’s staining to validate and confirm the findings of the retrospective part.Univariate and multivariate analyses were carried out to detect the independent factors that can affect the visualization of the distal mesorectal end.Results:The terminal line(TL)is the distal mesorectal end of the transabdominal and transanal TME(taTME)and appears as a remarkable pearly white fascial structure extending posteriorly from 2 to 10 o’clock.Histopathological examination revealed that the fascia propria of the rectum merges with the presacral fascia at the TL,beyond which the mesorectum ends,with no further downward extension.In the retrospective observation,the TL was seen in 56.6%of transabdominal TME and 56.0%of taTME operations.Surgical approach and tumor distance from the anal verge were the independent variables that directly influenced the detection of the TL(P=0.03 and P=0.01).Conclusion: The TL is a visible sign where the transabdominal TME should end and the taTME should begin. Recognitionof the mesorectal end may impact the certainty of complete mesorectum inclusion. Further clinical trials are needed toconfirm the preliminary findings. | Waleed M.Ghareeb Xiaojie Wang Xiaozhen Zhao Meirong Xie Sameh H.Emile Sherief Shawki Pan Chi | 2022 | Gastroenterology Report2022，10，1： | 1 |

| 12 | Synthesis of naphthalene derivatives through inexpensive BF_3·Et_2O-catalyzed annulation reaction of arylacetaldehydes with arylalkynes显示文摘An inexpensive BF3·Et2O-catalyzed annulation reaction of arylacetaldehydes with arylalkynes has been developed. Various substituted phenylacetaldehydes and phenylacetylenes can undergo this reaction, producing corresponding α-aryl substituted naphthalene derivatives. Use of inexpensive and readily available BF3 ·Et2O catalyst constitutes the most attractive advantage of this transformation. | XIANG ShiKai HU Hao MA Jing LI YuanZhuo WANG BiQin FENG Chun ZHAO KeQing HU Ping CHEN XiaoZhen | 2013 | Science China Chemistry2013，56，7： | 0 |
| 13 | Pepper variome reveals the history and key loci associated with fruit domestication and diversification显示文摘Pepper(Capsicum spp.)is an important vegetable crop that provides a unique pungent sensation when eaten.Through construction of a pepper variome map,we examined the main groups that emerged during domestication and breeding of C.annuum,their relationships and temporal succession,and the molecular events underlying the main transitions.The results showed that the initial differentiation in fruit shape and pungency,increase in fruit weight,and transition from erect to pendent fruits,as well as the recent appearance of large,blocky,sweet fruits(bell peppers),were accompanied by strong selection/fixation of key alleles and introgressions in two large genomic regions.Furthermore,we identified Up,which encodes a BIG GRAIN protein involved in auxin transport,as a key domestication gene that controls erect vs pendent fruit orientation.The up mutation gained increased expression especially in the fruit pedicel through a 579-bp sequence deletion in its 5′upstream region,resulting in the phenotype of pendent fruit.The function of Up was confirmed by virus-induced gene silencing.Taken together,these findings constitute a cornerstone for understanding the domestication and differentiation of a key horticultural crop. | Yacong Cao Kang Zhang Hailong Yu Shumin Chen Donghui Xu Hong Zhao Zhenghai Zhang Yinqing Yang Xiaozhen Gu Xinyan Liu Haiping Wang Yaxin Jing Yajie Mei Xiang Wang Véronique Lefebvre Weili Zhang Yuan Jin Dongliang An Risheng Wang Paul Bosland Xixiang Li IIan Paran Baoxi Zhang Giovanni Giuliano Lihao Wang Feng Cheng | 2022 | Molecular Plant2022，15，11： | 0 |
| 14 | Identification and Characterization of a Novel Yellow Leaf Mutant yl1 in Rice显示文摘Leaf-color mutants play an important role in the study of chlorophyll metabolism,chloroplast development,and photosynthesis system.In this study,the yellow leaf 1(yl1)rice mutant was identified from the ethyl methane sulfonate-treated mutant progeny of Lailong,a glutinous japonica rice landrace cultivated in Guizhou Province,China.Results showed that yl1 exhibited yellow leaves with decreased chlorophyll content throughout the growth period.Chloroplast development in the yl1 mutant was disrupted,and the grana lamellae was loosely packed and disordered.RNA sequencing and real-time quantitative polymerase chain reaction(qRT-PCR)analysis revealed that the chlorophyll synthesis-related genes OsCHLH,OsCHLM,OsCHLG,PORB,and YGL8,as well as the chloroplast development-related genes FtsZ,OsRpoTp,and RbcL,were down-regulated in the yl1 mutant.Genetic analysis revealed that the yellow leaf phenotype of yl1 was controlled by recessive nuclear gene.By employing the MutMap method,the mutation responsible for the phenotype was mapped to a 6.17 Mb region between 17.34 and 23.51 Mb on chromosome 3.Two non-synonymous single-nucleotide polymorphisms(SNPs)located in the gene locus LOC_Os03g31210 and LOC_Os03g36760 were detected in this region.The two SNPs were further confirmed by PCR and Sanger sequencing.The expression patterns of the two candidate genes indicated that LOC_Os03g36760 showed greater potential for functional verification.Subcellular protein localization revealed that the encoded product of LOC_Os03g36760 was localized in the nucleus,cytoplasm,and plasma membrane.These results will be useful for further characterization and cloning of the yl1 gene,and for research on the molecular mechanisms controlling biogenesis and chloroplast biochemical processes. | Xiaofang Zeng Guangzheng Li Nu’an Liu Yan Li Jianrong Li Xiaozhen Huang Degang Zhao | 2022 | Phyton-International Journal of Experimental Botany2022，91，11： | 0 |
| 15 | Molecular regulation of tomato male reproductive development显示文摘The reproductive success of flowering plants,which directly affects crop yield,is sensitive to environmental changes.A thorough understanding of how crop reproductive development adapts to climate changes is vital for ensuring global food security.In addition to being a high-value vegetable crop,tomato is also a model plant used for research on plant reproductive development.Tomato crops are cultivated under highly diverse climatic conditions worldwide.Targeted crosses of hybrid varieties have resulted in increased yields and abiotic stress resistance;however,tomato reproduction,especially male reproductive development,is sensitive to temperature fluctuations,which can lead to aborted male gametophytes,with detrimental effects on fruit set.We herein review the cytological features as well as genetic and molecular pathways influencing tomato male reproductive organ development and responses to abiotic stress.We also compare the shared features among the associated regulatory mechanisms of tomato and other plants.Collectively,this review highlights the opportunities and challenges related to characterizing and exploiting genic male sterility in tomato hybrid breeding programs. | Dandan Yang Zhao Wang Xiaozhen Huang Cao Xu | 2023 | aBIOTECH2023，4，1： | 0 |

| 17 | Synthesis,characterization and properties of diamidodisilanes and azocyclosilane显示文摘Several diamidodisilanes and azocyclosilane were prepared from the resultants of Wurtz coupling reaction between dichlorosilane and sodium and characterized by 1H NMR and FT-IR. The two split peaks of the stretching vibration bonds of Si-H bonds in compounds 1 and 3 were firstly found at ~2163 cm-1 and ~2100 cm-1 respectively. The density functional theory was adopted to calculate the several stable geometrical isomerism structures of compounds 1 and 3. The results of the calculations show that the peak split of Si-H bonds stretching vibration absorption was caused by the different geometrical isomers of the compounds and the calculated IR spectra of compounds 1 and 3 are much closer to the experimental results. The processes of hydrolysis and polycondensation reactions of the synthetic compounds were studied by FT-IR. At the same time, the transition of Si-H bonds split peaks was observed in this procedure. As the results of the hydrolysis and condensation reactions, a new type of organic silicon polymer, polyoxydisilane was obtained, which presents the photoluminescence of the polysilanes. | CUI Mengzhong ZHAO Yixin ZHANG Bin XI jingyu WANG Shuguang TANG Xiaozhen | 2005 | Chinese Science Bulletin2005，50，15： | 0 |
| 18 | Identification of lipopolysaccharide-binding protein as a novel citrullinated autoantigen in rheumatoid arthritis显示文摘Background:A specific feature of the autoimmune response in rheumatoid arthritis(RA)is the presence of anti-citrullinated protein antibodies(ACPAs)in patient sera.These antibodies can appear several years before disease onset and are involved in the development of RA.Objective:We performed proteomic analysis by mass spectroscopy to identify novel citrullinated antigens and autoantibodies in RA patients.Methods:Polypeptides isolated from the sera of RA patients were identified by Orbitrap high-precision mass spectrometry and then citrulline-containing proteins were selected.The levels of ACPAs against these newly identified citrullinated autoantigens in sera of 100 RA patients and 50 healthy controls were determined by enzyme-linked immunosorbent assays.Results:A total of 135 proteins were identified in RA patients and the protein profile included 11 citrulline-containing antigens.Three of the 11 citrullinated proteins had been reported in previous studies.ACPAs against the novel citrullinated epitopes from these proteins were increased in sera from the RA patients compared with those from healthy controls.Autoantibodies against one of the citrullinated antigens,lipopolysaccharide-binding protein(LBP),was significantly increased in RA patients and associated with disease activities.The titer of anti-citrullinated LBP antibodies(anti-cLBP)was closely related to the infection incidence in RA patients.Conclusion:Serum protein analysis by high-precision proteomic technology is a feasible method to identify novel citrullinated epitopes in RA patients.Anti-cLBP antibodies are associated with disease severity and infection in RA patients. | Xiaozhen Zhao Yuling Chen Wen Wen Yongjing Cheng Ru Li Xu Liu Yuhui Li Rulin Jia Haiteng Deng Zhanguo Li Xiaolin Sun | 2022 | Rheumatology & Autoimmunity2022，2，1： | 0 |
| 19 | Production and characterization of monoclonal antibodies against grass carp CD4-1 and CD4-2显示文摘CD4 T helper cells are an important group of cells in the immune system of vertebrates and express CD4 receptor on the cell surface.In mammals,the CD4 receptor is encoded by a single copy gene,whilst in fish,two copies of cd4 genes,namely cd4-1 and cd4-2,are found.In this study,the ectodomains of grass carp(Ctenopharyngodon idella,Ci)CD4-1 and CD4-2 were expressed in the E.coli cells and used to generate monoclonal antibodies in mice.Western blotting,confocal microscopy and flow cytometry were performed to characterize the monoclonal antibodies.It has been shown that the CiCD4-1 and CiCD4-2 monoclonal antibodies had good specificity to react with the recombinant ectodomains of CiCD4-1 and CiCD4-2 expressed in the CHO-S cells and the native CD4 molecules of grass carp.The CiCD4-1 monoclonal antibody did not recognize CiCD4-2 and verse versa.In addition,the CD4-1 and CD4-2 monoclonal antibodies specifically recognized the CD4-1 and CD4-2 receptors expressed in the HEK293 cells and native molecules of fish cells.Further,the percentages of lymphocytes in immune tissues of healthy fish were analyzed by flow cytometry.It was found that 17.6%of lymphocytes were CD4-1^(+)cells and 22.5%were CD4-2^(+)in the head kidney.In the spleen,13.1%of lymphocytes were CD4-1^(+)and 18.6%were CD4-2^(+)while 7.3%of blood lymphocytes were CD4-1^(+)cells and 8.8%were CD4-2^(+)cells.The availability of the CD4-1 and CD4-2 monoclonal antibodies provides antibody-based tools for further elucidation of the functions of CD4 T cells in grass carp. | Bangjie Wang Yuting Qin Zhaosheng Sun Xiaozhen Zhu Zhao Jia Kangyong Chen Danjie Liu Junya Wang Jun Zou | 2024 | Aquaculture and Fisheries2024，9，2： | 0 |
| 20 | DWARF and SMALL SEED1,a Novel Allele of OsDWARF,Controls Rice Plant Architecture,Seed Size,and Chlorophyll Biosynthesis显示文摘Plant architecture is a vital agronomic trait to control yield in rice(Oryza sativa L.).A dwarf and small seed 1(dss1)mutant were obtained from the ethyl methanesulfonate(EMS)mutagenized progeny of a Guizhou glutinous landrace cultivar,Lipingzabianhe.The dss1 mutant displayed phenotypes similar to those of brassinosteroid(BR)deficient mutants,such as dwarfing,dark green and rugose erect leaves,small seeds,and loner neck internode panicles with primary branching.In our previous study,the underlying DSS1 gene was isolated,a novel allele of OsDWARF(OsBR6ox)that encodes a cytochrome P450 protein involved in the BR biosynthetic pathway by MutMap technology.In this work,we confirmed that a Thr335Ile amino acid substitution residing in DSS1/OsDWARF was responsible for the dwarf,panicle architecture,and small seed phenotypes in the dss1 mutants by genetic transformation experiments.The overexpression of OsDWARF in the dss1 mutant background could not only recover dss1 to the normal plant height and panicle architecture but also rescued normal leaf angles,seed size,and leaf color.Thus,the specific mutation in DSS1/OsDWARF influenced plant architecture,seed size,and chlorophyll biosynthesis. | Yan Li Renquan Huang Jianrong Li Xiaozhen Huang Xiaofang Zeng Degang Zhao | 2021 | Phyton-International Journal of Experimental Botany2021，90，1： | 0 |
