| 1 | Exome sequencing confirms molecular diagnoses in 38 Chinese families with hereditary spherocytosis显示文摘Hereditary spherocytosis(HS), the most common cause of congenital hemolytic anemia, is caused by deficiency of the erythrocyte membrane proteins. Five causative genes(ANK1, SPTB, SPTA1, SLC4 A1, and EPB42) have been identified. To date,molecular genetic studies have been performed in different populations, including the American, European, Brazilian, Japanese and Korean populations, whereas only a few studies have been described in the Chinese population. Here, by reanalysis of the exome data, we revealed causative mutations and established a definitive diagnosis of HS in all 38 Chinese families. We found 34 novel mutations and four reported mutations in three known HS-causing genes—17 in ANK1, 17 in SPTB and four in SLC4 A1,suggesting that ANK1 and SPTB are the major genes in Chinese patients with HS. All of the ANK1 or SPTB mutations, scattered throughout the entire genes, are non-recurrent; and most of them are null mutations, which might cause HS via a haploinsufficiency mechanism. De novo mutations in ANK1 or SPTB often occur with an unexpected high frequency(87.5% and64.2%, respectively). Our study updates our knowledge about the genetic profile of HS in Chinese and shows that family-based,especially parent-offspring trio, sequencing analysis can help to increase the diagnostic power and improve diagnostic efficiency. | Rongrong Wang Shuanghao Yang Ming Xu Jia Huang Hongyan Liu Weiyue Gu Xue Zhang | 2018 | Science China(Life Sciences)2018，61，8： | 22 |
| 2 | Single-Atom Catalysts for Electrochemical Hydrogen Evolution Reaction: Recent Advances and Future Perspectives显示文摘Hydrogen,a renewable and outstanding energy carrier with zero carbon dioxide emission,is regarded as the best alternative to fossil fuels.The most preferred route to large-scale production of hydrogen is by water electrolysis from the intermittent sources(e.g.,wind,solar,hydro,and tidal energy).However,the efficiency of water electrolysis is very much dependent on the activity of electrocatalysts.Thus,designing high-effective,stable,and cheap materials for hydrogen evolution reaction(HER)could have a substantial impact on renewable energy technologies.Recently,single-atom catalysts(SACs)have emerged as a new frontier in catalysis science,because SACs have maximum atom-utilization efficiency and excellent catalytic reaction activity.Various synthesis methods and analytical techniques have been adopted to prepare and characterize these SACs.In this review,we discuss recent progress on SACs synthesis,characterization methods,and their catalytic applications.Particularly,we highlight their unique electrochemical characteristics toward HER.Finally,the current key challenges in SACs for HER are pointed out and some potential directions are proposed as well. | Zonghua Pu Ibrahim Saana Amiinu Ruilin Cheng Pengyan Wang Chengtian Zhang Shichun Mu Weiyue Zhao Fengmei Su Gaixia Zhang Shijun Liao Shuhui Sun | 2020 | Nano-Micro Letters2020，12，2： | 10 |
| 3 | Mutation profile and its correlation with clinicopathology in Chinese hepatocellular carcinoma patients显示文摘Background:Hepatocellular carcinoma(HCC)is one of the most common causes of cancer worldwide.Although many studies have focused on oncogene characteristics,the genomic landscape of Chinese HCC patients has not been fully clarified.Methods:A total of 165 HCC patients,including 146 males and 19 females,were enrolled.The median age was 55 years(range,27-78 years).Corresponding clinical and pathological information was collected for further analysis.A total of 168 tumor tissues from these patients were selected for next-generation sequencing(NGS)-based 450 panel gene sequencing.Genomic alterations including single nucleotide variations(SNV),short and long insertions and deletions(InDels),copy number variations,and gene rearrangements were analyzed.Tumor mutational burden(TMB)was measured by an algorithm developed in-house.The top quartile of HCC was classified as TMB high.Results:A total of 1,004 genomic alterations were detected from 258 genes in 168 HCC tissues.TMB values were identified in 160 HCC specimens,with a median TMB of 5.4 Muts/Mb(range,0-28.4 Muts/Mb)and a 75%TMB of 7.7 Muts/Mb.The most commonly mutated genes were TP53,TERT,CTNNB1,AXIN1,RB1,TSC2,CCND1,ARID1A,and FGF19.SNV was the most common mutation type and C:G>T:A and guanine transformation were the most common SNVs.Compared to wild-type patients,the proportion of Edmondson grade III-IV and microvascular invasion was significantly higher in TP53 mutated patients(P<0.05).The proportion of tumors invading the hepatic capsule was significantly higher in TERT mutated patients(P<0.05).The proportion of Edmondson grade I-II,alpha fetoprotein(AFP)<25μmg/L,and those without a history of hepatitis B was significantly higher in CTNNB1 mutated patients(P<0.05).CTNNB1 mutations were associated with TMB high in HCC patients(P<0.05).Based on correlation analysis,the mutation of TP53 was independently correlated with microvascular invasion(P=0.002,OR=3.096)and Edmondson grade III-IV(P=0.008,OR=2.613).The mutation of TERT was independently correlated with tumor invasion of the liver capsule(P=0.001,OR=3.030),and the mutation of CTNNB1 was independently correlated with AFP(<25μmg/L)(P=0.009,OR=3.414).Conclusions:The most frequently mutated genes of HCC patients in China were TP53,TERT,and CTNNB1,which mainly lead to the occurrence and development of HCC by regulating the P53 pathway,Wnt pathway,and telomere repair pathway.There were more patients with microvascular invasion and Edmondson III-IV grade in TP53 mutated patients and more patients with hepatic capsule invasion in TERT mutated patients,while in CTNNB1 mutated patients,there were more patients with Edmondson I-II grade,AFP<25μmg/L,and a non-hepatitis B background.Also,the TMB values were significantly higher in CTNNB1 mutated patients than in wild type patients. | Shuo Wang Huasheng Shi Tao Liu Manjiang Li Sanshun Zhou Xuan Qiu Zusen Wang Weiyu Hu Weidong Guo Xiaoqian Chen Honglin Guo Xiaoliang Shi Junping Shi Yunjin Zang Jingyu Cao Liqun Wu | 2021 | Hepatobiliary Surgery and Nutrition2021，10，2： | 8 |
| 4 | Dynamics of ecosystem carbon stocks during vegetation restoration on the Loess Plateau of China显示文摘In the last few decades, the Loess Plateau had experienced an extensive vegetation restoration to reduce soil erosion and to improve the degraded ecosystems. However, the dynamics of ecosystem carbon stocks with vegetation restoration in this region are poorly understood. This study examined the changes of carbon stocks in mineral soil(0–100 cm), plant biomass and the ecosystem(plant and soil) following vegetation restoration with different models and ages. Our results indicated that cultivated land returned to native vegetation(natural restoration) or artificial forest increased ecosystem carbon sequestration. Tree plantation sequestered more carbon than natural vegetation succession over decades scale due to the rapid increase in biomass carbon pool. Restoration ages had different effects on the dynamics of biomass and soil carbon stocks. Biomass carbon stocks increased with vegetation restoration age, while the dynamics of soil carbon stocks were affected by sampling depth. Ecosystem carbon stocks consistently increased after tree plantation regardless of the soil depth; but an initial decrease and then increase trend was observed in natural restoration chronosequences with the soil sampling depth of 0–100 cm. Moreover, there was a time lag of about 15–30 years between biomass production and soil carbon sequestration in 0–100 cm, which indicated a long-term effect of vegetation restoration on deeper soil carbon sequestration. | WANG Kaibo DENG Lei REN Zongping SHI Weiyu CHEN Yiping SHANG-GUAN Zhouping | 2016 | Journal of Arid Land2016，8，2： | 7 |
| 5 | Homozygous loss-of-function mutations in FSIP2 cause male infertility with asthenoteratospermia显示文摘Male infertility, as a major issue of human reproduction health, prevents successful natural conception. Asthenoteratospermia mainly presents one or multiple anomalies in head, neck and tail of spermatozoa, and impairs sperm function and motility (Coutton et al., 2015). Recurrent abnormalities of the fibrous sheath lead to multiple morphological abnormaliries of the sperm flagella (MMAF), which is a quite frequent type of asthenoteratospermia in male infertility (Chemes et al., 1987;Ben Khelifa et al, 2014). | Wangjie Liu Huan Wu Li Wang Xiaoyu Yang Chunyu Liu Xiaojin He Weiyu Li Jiajia Wang Yujie Chen Hongyan Wang Yang Gao Shuyan Tang Shenmin Yang Li Jin Feng Zhang Yunxi Cao | 2019 | Journal of Genetics and Genomics2019，46，1： | 7 |
| 6 | Cloning of Ln Gene Through Combined Approach of Map-based Cloning and Association Study in Soybean显示文摘Increasing yield is one of the most important goals in crop breeding.Soybean(Glycine max L.Merr.),one of the most economically important leguminous seed crops,provides the majority of plant proteins,and more than a quarter of the world's food and animal feed(Graham and Vance,2003). The yield of soybean is finally determined by the number of seeds per unit area,which affected by many characters,such as height,branching number,photosynthesis,seed size,seed number.The number of seeds per pod is taken for one of the critical components that related to yield(You et al.,1995),and it has long been considered in soybean production(Takahashi, | Chao Fang Weiyu Li Guiquan Li Zheng Wang Zhengkui Zhou Yanming Ma Yanting Shen Congcong Li Yunshuai Wu Baoge Zhu Weicai Yang Zhixi Tian | 2013 | Journal of Genetics and Genomics2013，40，2： | 7 |

| 9 | Ambient Backscatter Communications over NOMA Downlink Channels显示文摘In this paper,we investigate the performance of commensal ambient backscatter communications(AmBC)that ride on a non-ortho go nal multiple access(NOMA)downlink transmission,in which a backscatter device(BD)splits part of its received signals from the base station(BS)for energy harvesting,and backscatters the remaining received signals to transmit information to a cellular user.Specifically,under the power consumption constraint at BD and the peak transmit power constraint at BS,we derive the optimal reflection coefficient at BD,the optimal total transmit power at BS,and the optimal power allocation at BS for each transmission block to maximize the ergodic capacity of the ambient backscatter transmission on the premise of preserving the outage performance of the NOMA downlink transmission.Furthermore,we consider a scenario where the BS is restricted by a maximum allowed average transmit power and the reflection coefficient at BD is fixed due to BD’s low-complexity nature.An algorithm is developed to determine the optimal total transmit power and power allocation at BS for this scenario.Also,a low-complexity algorithm is proposed for this scenario to reduce the computational complexity and the signaling overheads.Finally,the performance of the derived solutions are studied and compared via numerical simulations. | Weiyu Chen Haiyang Ding Shilian Wang Daniel Benevides daCosta Fengkui Gong Pedro Henrique Juliano Nardelli | 2020 | China Communications2020，17，6： | 4 |

| 11 | Efficacy of inverso isomer of CendR peptide on tumor tissue penetration显示文摘The dense extracellular matrix and high interstitial fluid pressure of tumor tissues prevent the ability of anti-tumor agents to penetrate deep into the tumor parenchyma for treatment effects. C-end rule(CendR) peptides can enhance the permeability of tumor blood vessels and tumor tissues via binding to neuropilin-1(NRP-1), thus aiding in drug delivery. In this study, we selected one of the CendR peptides(sequence RGERPPR) as the parent L-peptide and substituted D-amino acids for the L-amino acids to synthesize its inverso peptide D(RGERPPR). We investigated the NRP-1 binding activity and tumorpenetrating ability of D(RGERPPR). We found that the binding affinity of D(RGERPPR) with NRP-1 and the cellular uptake was significantly higher than that of RGERPPR. Evans Blue tests revealed that D(RGERPPR) exhibited improved tumor-penetrating ability in C6, U87 and A549 tumor-bearing nude mice. Using nude mice bearing A549 xenograft tumors as a model, we found that the rate of tumor growth in the group co-administered with D(RGERPPR) and gemcitabine(Gem) was significantly lower than the gemcitabine-treated group with a tumor suppression rate(TSR%) of 55.4%. Together, our results demonstrate that D(RGERPPR) is a potential tumor-penetrating peptide. | Ruifeng Wang Qing Shen Xue Li Cao Xie Weiyue Lu Songli Wang Jing Wang Dongli Wang Min Liu | 2018 | Acta Pharmaceutica Sinica B2018，8，5： | 3 |

| 13 | SPDEF suppresses head and neck squamous cell carcinoma progression by transcriptionally activating NR4A1显示文摘SAM pointed domain containing E26 transformation-specific transcription factor(SPDEF)plays dual roles in the initiation and development of human malignancies.However,the biological role of SPDEF in head and neck squamous cell carcinoma(HNSCC)remains unclear.In this study,the expression level of SPDEF and its correlation with the clinical parameters of patients with HNSCC were determined using TCGA-HNSC,GSE65858,and our own clinical cohorts.CCK8,colony formation,cell cycle analysis,and a xenograft tumor growth model were used to determine the molecular functions of SPDEF in HNSCC.ChIP-qPCR,dual luciferase reporter assay,and rescue experiments were conducted to explore the potential molecular mechanism of SPDEF in HNSCC.Compared with normal epithelial tissues,SPDEF was significantly downregulated in HNSCC tissues.Patients with HNSCC with low SPDEF mRNA levels exhibited poor clinical outcomes.Restoring SPDEF inhibited HNSCC cell viability and colony formation and induced G0/G1 cell cycle arrest,while silencing SPDEF promoted cell proliferation in vitro.The xenograft tumor growth model showed that tumors with SPDEF overexpression had slower growth rates,smaller volumes,and lower weights.SPDEF could directly bind to the promoter region of NR4A1 and promoted its transcription,inducing the suppression of AKT,MAPK,and NF-κB signaling pathways.Moreover,silencing NR4A1 blocked the suppressive effect of SPDEF in HNSCC cells.Here,we demonstrate that SPDEF acts as a tumor suppressor by transcriptionally activating NR4A1 in HNSCC.Our findings provide novel insights into the molecular mechanism of SPDEF in tumorigenesis and a novel potential therapeutic target for HNSCC. | Yanting Wang Xianyue Ren Weiyu Li Ruoyan Cao Suyang Liu Laibo Jiang Bin Cheng Juan Xia | 2021 | International Journal of Oral Science2021，13，4： | 3 |
| 14 | Folic acid-conjugated liposomal vincristine for multidrug resistant cancer therapy显示文摘We encapsulated vincristine into folic acid-conjugated PEGylated liposomes to improve the anti-tumor efficacy on multidrug resistant cancers.It was observed that the drug delivery system we constructed exhibited maximum cytotoxicity on KBv200 cells(multidrug resistant variant)compared with any other formulations.The semi-quantitative analysis of region of interest revealed that there was a great increase in area under curve(AUC)of a near-infrared fluorescein in solid tumors due to folic acid-mediated accumulation.Folic acid-conjugated PEGylated liposomes showed a significant tumor growth inhibiting effect in vitro and in vivo.TUNEL assay revealed that folic acid-conjugated PEGylated liposomes could induce cell apoptosis much more greatly than others.This study demonstrated that it had potential application prospective for the treatment of multidrug resistant cancer. | Chenyu Wang Linglin Feng Xiangkun Yang Fei Wang Weiyue Lu | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，2： | 3 |
| 15 | Preparation of MCM-41-supported chiral Salen Mn (III) catalysts and their catalytic properties in the asymmetric epoxidation of olefins显示文摘A secondary amino-modified mesoporous molecular sieve MCM-41 was obtained by reaction of bis(3-(triethoxysilyl)propyl)amine with MCM-41. The chiral Salen-Mn (III) complex was anchored onto the modified MCM-41 by a multi-step grafting method and two heterogenized catalysts with different Mn contents were obtained. The catalysts were characterized by XRD, N2 adsorption, ICP, FT-IR and DR UV-Vis. Their catalysis on asymmetric epoxidation of several olefins was studied with NaClO and m-CPBA as oxidants respectively. It was found that both the activity and enantioselectivity of the cata- lysts decreased after the homogeneous catalyst was heterogenized. The reasons resulting in the de- crease of catalytic performance were discussed. | ZHAO DongMin ZHAO JiQuant ZHAO ShanShan HE LeQin WANG WeiYu | 2007 | Chinese Science Bulletin2007，52，17： | 3 |
| 16 | LHCGR and ALMS1 defects likely cooperate in the development of polycystic ovary syndrome indicated by double-mutant mice显示文摘Polycystic ovary syndrome(PCOS)is a heterogeneous disorder with evidence of polygenetic components,and obesity may be a risk factor for hyperandrogen ism.Previous studies have shown that LHCGR is en riched in the ovary and LHCGR deficiency causes infertility without typical PCOS phenotypes.ALMS1 is implicated in obesity and hyperandrogenism,the common phenotypes among PCOS patients.Through whole-exome sequencing of 22 PCOS families and targeted candidate gene sequencing of additional 65 sporadic PCOS patients,we identified potential causative mutations in LHCGR and ALMS1 in a sibling-pair PCOS family and three sporadic PCOS patients.The expression of LHCGRL638 P in granulosa-like tumor cell line(KGN)cells promoted cyclic adenosine monophosphate production and granulosa cell proliferation,indicating that LHCGRL638 P is an activating mutation.Lhcgr~(L642 P/L642 P)mice showed an irregular estrous cycle,reduced follicles with dynamic folliculogenesis,and increased testosterone(T),estradiol(E2),and dehydroepiandrosterone.Lhcgr~(+/L642 P)AIms1~(+/PB)mice displayed increased T and E2 but decreased late secondary and preovulatory follicles.We showed that activating mutation of LHCGR likely plays important roles in the pathophysiology of PCOS involving abnormal reproductive physiology,whereas ALMS1 deficiency may promote anovulatory infertility via elevated androgens,suggesting that the disturbed LHCGR and ALMS1 cooperatively induce PCOS phenotypes,characterized as anovulation and hyperandrogenemia frequently observed in PCOS patients with obesity. | Li Yu Lina Wang Wufan Tao Wenxiang Zhang Shuanghao Yang Jian Wang Jia Fei Rui Peng Yiming Wu Xiumei Zhen Hong Shao Weiyue Gu Rong Li Bai-Lin Wu Hongyan Wang | 2021 | Journal of Genetics and Genomics2021，48，5： | 3 |
| 17 | Key Factors for Efficient Consumption of Renewable Energy in a Provincial Power Grid in Southern China显示文摘The development of renewable energy sources(RES)is important to promote the energy transition and address climate change.Unlike the centralized RES power plants in the north of China,the distributed RES power plants in the south of China for achieving local consumption have become an effective alternative.However,the differences between RES and hydropower consumption have become obvious in some areas.This paper investigates the key factors affecting the abandonment of RES in the south of China.To alleviate the problem of RES consumption,various measures are discussed from the aspects of evaluating the consumption capacity of power grids at different voltage levels,optimizing demand-side management,flexibly for reforming the peak-shaving power sources of thermal power plants and strengthening inter-provincial transactions.The production simulation is used to validate the analysis and discussion. | Ming Wen Yong Li Xintao Xie Yijia Cao Yaowu Wu Weiyu Wang Li He Yu Cao Binkun Xu Limiao Huang | 2020 | CSEE Journal of Power and Energy Systems2020，6，3： | 3 |

| 19 | Ultra-small hollow ternary alloy nanoparticles for efficient hydrogen evolution reaction显示文摘Hollow nanoparticles with large specific surface area and high atom utilization are promising catalysts for the hydrogen evolution reaction(HER). We describe herein the design and synthesis of a series of ultra-small hollow ternary alloy nanostructures using a simple one-pot strategy. The same technique was demonstrated for hollow PtNiCu nanoparticles, hollow PtCoCu nanoparticles and hollow CuNiCo nanoparticles. During synthesis, the displacement reaction and oxidative etching played important roles in the formation of hollow structures. Moreover, our hollow PtNiCu and PtCoCu nanoparticles were single crystalline, with an average diameter of 5 nm. Impressively, ultra-small hollow PtNiCu nanoparticles,containing only 10% Pt, exhibited greater electrocatalytic HER activity and stability than a commercial Pt/C catalyst. The overpotential of hollow Pt Ni Cu nanoparticles at 10 mA cm^(-2) was 28 mV versus reversible hydrogen electrode(RHE). The mass activity was 4.54 A mg Pt^(-1) at-70 mV versus RHE, which is 5.62-fold greater than that of a commercial Pt/C system(0.81 A mg Pt^(-1)). Through analyses of bonding and antibonding orbital filling, density functional theory calculations demonstrated that the bonding strength of different metals to the hydrogen intermediate(H*) was in the order of Pt > Co > Ni > Cu. The excellent HER performance of our hollow PtNiCu nanoparticles derives from moderately synergistic interactions between the three metals and H*. This work demonstrates a new strategy for the design of low-cost and high-activity HER catalysts. | Zhenxing Li Chengcheng Yu Yikun Kang Xin Zhang Yangyang Wen Zhao-Kui Wang Chang Ma Cong Wang Kaiwen Wang Xianlin Qu Miao He Ya-Wen Zhang Weiyu Song | 2021 | National Science Review2021，8，7： | 2 |
| 20 | The effects of two free-floating plants (Eichhornia crassipes and Pistia stratiotes) on the burrow morphology and water quality characteristics of pond loach (Misgurnus anguillicaudatus) habitat显示文摘Loach exhibit conspicuous drilling behaviors in the mud of shallow waters,yet their burrow morphology and the factors affecting this behavior have received little attention.We characterized the burrow morphology and water quality of the pond loach Misgurnus anguillicaudatus in three scenarios:in tanks without plants,tanks with the free-floating plant water hyacinth Eichhornia crassipes,and tanks with water lettuce Pistia stratiotes.Water hyacinth effectively removed water TN,COD,NO3-N and NH4-N,and water lettuce removed water TP and NH4-N.Water hyacinth and water lettuce markedly reduced water turbidity and DO,increased TOC and EC.Water hyacinth purified water more effectively than water lettuce,providing a suitable habitat for loach feeding,living and burrowing.The burrow structures were V-shaped,Y-shaped,inverted L-shaped,or complicated dendritic networks composed of multiple V shapes.The hyacinth treatment was characterized by the greatest burrow volume,length,depth,and structural complexity,but the opening size was reduced by dense root mat coverage.Burrows in the water lettuce treatment were characterized by intermediate volume,length,branches and sinuosity,but they had the largest opening and pit size.The control treatment had a flat bottom with the smallest,shortest burrows.This study indicates that free-floating plants improve habitat suitability and change burrow morphology and may be used to improve loach breeding methods。 | Jinqing Wang Guihua Fu Weiyue Li Ying Shi Jicai Pang Qiang Wang Weiguang Lü Change Liu Jiansheng Liu | 2018 | Aquaculture and Fisheries2018，3，1： | 2 |
