| 1 | Characteristics of hydrocarbon accumulation and exploration potential of the northern South China Sea deepwater basins显示文摘Although the huge potential of the northern South China Sea deepwater basins has been proven by a series of discoveries that followed the exploration breakthrough of well LW 3-1-1, recent drilling and other studies have demonstrated the uniqueness and complicated nature of hydrocarbon accumulations of the deepwater basins there. Based on a review of previous work and the latest exploration activities and studies, the purpose of this paper is to discuss the critical controls for hydrocarbon accumulations in the deepwater basins of the northern South China Sea. A terrestrial-marine transitional coal-bearing source rock is proposed to be the primary source rock for the deepwater basins. A marine source rock, which was first identified as contributing to hydro-carbon generation in this region, probably plays a significant role in the deep-and ultra-deep water basins south to the Pearl River Mouth and Qingdongnan basins. The shelf margin delta depositional systems in the Baiyun Sag, sourced from the Pearl River, are currently primary exploration targets in the deepwater part of the Pearl River Mouth Basin, whereas the western Red River delta-ic-submarine fan depositional systems, initially proven by drilling, are the possible major exploration reservoirs in the Qing-dongnan deepwater areas. Current deepwater exploration targets at the large-sized structural traps and deep and ultra-deep areas in the south of the Pearl River Mouth and Qingdongnan basins will be the future exploration focus. Deepwater exploration activities and relevant fundamental studies, supporting and promoting each other, are of great importance to the national energy supply of China, the basic regional studies of the South China Sea, advancements in technology, and development of related deepwater industries, and will safeguard national sovereignty and territorial integrity. | ZHU WeiLin ZHONG Kai LI YouChuan XU Qiang FANG DianYong | 2012 | Chinese Science Bulletin2012，57，24： | 48 |
| 2 | A new type of leak-floor flip bucket显示文摘Flip buckets are commonly used to discharge flow away from a hydraulic structure into the downstream to dissipate energy.A new leak-floor flip bucket is presented,making the ski-jump water jet a typical long-narrow nappe.Based on the model experiments and numerical simulation,the flow pattern,formation process and mechanism of the leak-floor flip bucket are studied.The results show that cross section flow shape develops from the'Y-type'to'|-type',and this is because the natural pressure difference is generated when water flows through the leak-floor area and moves transversely from both sides to the center.Different from the slit-type flip bucket with sidewall contraction,the leak-floor flit bucket makes the water jet narrow and long without high pressure on the side walls of the flip bucket.Under the same jet length condition,the maximum sidewall pressure of the slit-type is 4.67 times that of the leak-floor flip bucket.The effects of flow discharge on the jet length are less significant for the leak-floor bucket than for the slit-type bucket. | DENG Jun YANG ZhengLi TIAN Zhong ZHANG FaXing WEI WangRu YOU Xiang XU WeiLin | 2016 | Science China(Technological Sciences)2016，59，4： | 15 |
| 3 | NUMERICAL SIMULATION OF FLOW THROUGH ORIFICE ENERGY-DISSIPATORS IN XIAOLANGDI FLOOD-DISCHAR-GE TUNNEL显示文摘The cavitation of orifi ces is one of the main problems of the Xiaolangdi flood discharge tunnels. Along with the decompression experiment, the flow field was calculated in this paper by using an axis-symmetrical k-ε turbulence model. The calculated pressur e distribution was compared with the measured data and in agreement with each ot her. The calculated results show that few of the cavitation bubbles generating a t the orifice edge can reach the wall under the calculation condition, the force applied on the orifice surface and the flow pattern before the orifice may be i mproved obviously by adding the vortex elimination ring at the upper side of the orifice. | Qu, Jingxue Xu, Weilin Yang, Yongquan Wang, Wei Diao, Mingjun | 2000 | Journal of Hydrodynamics2000，12，3： | 14 |
| 4 | A new type of plunge pool―Multi-horizontal submerged jets显示文摘Based on the understanding of the mechanism of energy dissipation,a new type of plunge pool is presented with the advantages of high rate of energy dissipation,low impact pressure,and small close-to-bed velocity on the soleplate of the plunge pool.The first advantage owes to enlarged shearing energy dissipation areas in the plunge pool,while the other two are caused by the jet that enters in a nearly horizontal level to keep the soleplate from being scoured directly.All of the above arrangements make this new type of energy dissipator distinct from the underflow energy dissipation.Through experiments on the physical model,the authors found that the water flow maintained stable and submerged in horizontal direction when the flow was narrow in horizontal but thick in vertical direction.However,the wide flat nappe was ready to submerge or float as the downstream water level rised or dropped.The entire flow fields of multi-horizontal submerged jets into plunge pool were also numerically simulated.The numerical results of water surface curve,close-to-bed velocity and floor pressure agree well with the experimental data.The flow pattern in the plunge pool was analyzed after combining the laboratory data and numerical simulation. | DENG Jun,XU WeiLin,ZHANG JianMing,QU JinXue & YANG YongQuan State Key Laboratory of Hydraulics and Mountain River Engineering,Sichuan University,Chengdu 610065,China | 2008 | Science China(Technological Sciences)2008，51，12： | 12 |
| 5 | Cavitation characteristics of pit structure in ultrasonic field显示文摘Bubble collecting, bubble holding and micro-bubble ejecting characteristics of pit structure and the influence of cavitation bubble on the development of erosion pit are investigated by means of highspeed photography experiments. Pits tend to collect and hold wandering cavitation bubbles. The air holding phenomenon of pits can be a destination of the incubation period in the process of cavitation erosion. The holding bubble tends to eject micro-bubbles from the top of holding cavitation bubble, making the pit a source of nuclei. With bubbles being held in pits, the diameters of pits increase rapidly. But in the given experiment condition, there is a specific stable value beyond which the diameter of pits will not increase. This characteristic will be helpful in understanding and predicting the cavitation erosion process. | BAI LiXin XU WeiLin ZHANG FaXing LI NaiWen ZHANG YiChi HUANG DeFa | 2009 | Science China(Technological Sciences)2009，52，7： | 11 |
| 6 | DISCHARGE DISTRIBUTION IN STRAIGHT COMPOUND CHANNELS显示文摘The existing methods of computing the flow distribution in compound channels with flood plains have been summarized in this paper. Due to the lower precision of hydraulic computation for a compound cross-section with two flood plains, a new method called the momentum-exchange method herein, is presented and verified with experimental and field data. The results show that the new method is more effective than the previous ones. | Wang, Wei Cai, Jinde Xu, Weilin | 1998 | Journal of Hydrodynamics1998，10，4： | 8 |
| 7 | Emergy footprint evaluation of hydropower projects显示文摘In the past thirty years, various hydropower projects, some with a dam height of over 300 m, have been planned and constructed within China. It is inevitable that these will have sizable effects on the environment, and it is crucial therefore to reasonably evaluate and control adverse effects. In this paper, the transformities of various items for hydropower projects were systematically analyzed, and an emergy footprint model for the projects was developed based on ecological footprint analyses and emergy theory, so that it can quantitatively evaluate the effects on the environment, both positive and negative, resulting from the whole process of planning, constructing and operating the projects. As an example, the effects of a large-scale hydropower project, the 'LP project', were investigated. The results showed that the hydropower projects have strong positive effects on the environment and can even in the short term balance the emergy footprint appropriation resulting from the construction and operation of the hydropower projects. Finally, suggestions were presented for the design of hydropower projects. | WU JianHua HE ChengLong XU WeiLin | 2013 | Science China(Technological Sciences)2013，56，9： | 7 |
| 8 | Cartilage-targeting peptide-modified dual-drug delivery nanoplatform with NIR laser response for osteoarthritis therapy显示文摘Cartilage-targeting delivery of therapeutic agents is still an effective strategy for osteoarthritis(OA)therapy.Recently,scavenging for reactive oxygen species(ROS)and activating autophagy have been increasingly reported to treat OA effectively.In this study,we designed,for the first time,a dual-drug delivery system based on metal organic framework(MOF)-decorated mesoporous polydopamine(MPDA)which composed of rapamycin(Rap)loaded into the mesopores and bilirubin(Br)loaded onto the shell of MOF.The collagen II-targeting peptide(WYRGRL)was then conjugated on the surface of above nanocarrier to develop a cartilage-targeting dual-drug delivery nanoplatform(RB@MPMW).Our results indicated the sequential release of two agents from RB@MPMW could be achieved via near-infrared(NIR)laser irritation.Briefly,the rapid release of Br from the MOF shell exhibited excellent ROS scavenging ability and anti-apoptosis effects,however responsively reduced autophagy activity,to a certain extent.Meanwhile,following the NIR irradiation,Rap was rapidly released from MPDA core and further enhanced autophagy activation and chondrocyte protection.RB@MPMW continuously phosphorylated AMPK and further rescued mitochondrial energy metabolism of chondrocytes following IL-1βstimulation via activating SIRT1-PGC-1αsignaling pathway.Additionally,the cartilage-targeting property of peptide-modified nanocarrier could be monitored via Magnetic Resonance(MR)and IVIS imaging.More significantly,RB@MPMW effectively delayed cartilage degeneration in ACLT rat model.Overall,our findings indicated that the as-prepared dual-drug delivery nanoplatform exerted potent anti-inflammation and anti-apoptotic effects,rescued energy metabolism of chondrocytes in vitro and prevented cartilage degeneration in vivo,which thereby showed positive performance for OA therapy. | Song Xue Xiaojun Zhou Weilin Sang Cong Wang Haiming Lu Yiming Xu Yiming Zhong Libo Zhu Chuanglong He Jinzhong Ma | 2021 | Bioactive Materials2021，6，8： | 5 |
| 9 | Nanocluster PtNiP supported on graphene as an efficient electrocatalyst for methanol oxidation reaction显示文摘In this study,phosphorus doped graphene supported PtNiP nanocluster electrocatalyst(PtNiP/P-graphene)was successfully prepared via a simple hypophosphite-assisted co-reduction method.The improved anchoring force and increased anchoring sites of graphene support result from phosphorus doping as well as size-confined growth effect of NaH_(2)PO_(2) leads to uniform dispersion of ultrafine PtNiP nanoclusters.Doped P also promotes the removal of CO-like intermediate by adjusting Pt electronic structure combining with alloyed Ni via electronic effects.As a result,the as-prepared PtNiP/P-graphene catalyst with more exposed active sites and optimized electronic structure of Pt alloy shows excellent electrocatalytic performances for methanol oxidation reaction(MOR)both in activity and durability in an acidic medium. | Long Yang Guoqiang Li Rongpeng Ma Shuai Hou Jinfa Chang Mingbo Ruan Wenbin Cai Zhao Jin Weilin Xu Guiling Wang Junjie Ge Changpeng Liu Wei Xing | 2021 | Nano Research2021，14，8： | 4 |
| 10 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 11 | High-speed photographic observation of collapse of two cavitation bubbles显示文摘Cavitation as a hydrodynamic phenomenon exists widely in water conservancy, shipbuilding, chemical and many other industries.Previous cavitation bubble dynamic studies mainly focused on single cavitation bubbles and their interaction with the wall. This paper studies the interaction between two cavitation bubbles under conditions with or without a wall. The results show that if the inception of two cavitation bubbles is not synchronized, the cavitation bubble of early inception collapse backwards the cavitation bubble of later inception; if the inception of two cavitation bubbles is synchronized, the two bubbles collapse towards each other; if a wall exists nearby, no matter whether the line connecting the centers of the two cavitation bubbles is vertical or parallel to the wall, the two cavitation bubbles collapse towards each other and then gradually merge, and the merged collapse body quickly moves to the wall. It is suggested that, as the number of cavitation bubbles increases, the cavitation erosion effect is not simply increased proportionally. Instead, mutual inhibitory effect may be demonstrated. | LUO Jing XU WeiLin LI Rui | 2016 | Science China(Technological Sciences)2016，59，11： | 3 |

| 14 | HLY78 Attenuates Neuronal Apoptosis via the LRP6/GSK3β/β-Catenin Signaling Pathway After Subarachnoid Hemorrhage in Rats显示文摘Neuronal apoptosis is one of the essential mechanisms of early brain injury after subarachnoid hemorrhage(SAH).Recently,HLY78 has been shown to inhibit apoptosis in tumor cells and embryonic cells c aused by carbon ion radiation through activation of the Wnt/β-catenin pathway.This study was designed to explore the anti-apoptotic role of HLY78 in experimental SAH.The results demonstrated that HLY78 attenuated neuronal apoptosis and the neurological deficits after SAH through the activation of low-density lipoprotein receptor-related protein 6(LRP6),which subsequently increased the level of phosphorylated glycogen synthesis kinase 3 beta(p-GSK3β)(Ser9),β-catenin,and Bcl-2,accompanied by a decrease of p-β-catenin,Bax,and cleaved caspase 3.An LRP6 small-interfering ribonucleic acid reversed the effects of HLY78.In conclusion,HLY78 attenuates neuronal apoptosis and improves neurological deficits through the LRP6/GSK3β/β-catenin signaling pathway after SAH in rats.HLY78 is a promising therapeutic agent to attenuate early brain injury after SAH. | Xu Luo Lina Li Weilin Xu Yuan Cheng Zongyi Xie | 2020 | Neuroscience Bulletin2020，36，10： | 3 |
| 15 | Operando HERFD-XANES and surface sensitive Δμ analyses identify the structural evolution of copper(Ⅱ) phthalocyanine for electroreduction of CO_(2)显示文摘The quantitative understanding of how atomic-level catalyst structural changes affect the reactivity of the electrochemical CO_(2)reduction reaction is challenging.Due to the complexity of catalytic systems,conventional in situ X-ray spectroscopy plays a limited role in tracing the underlying dynamic structural changes in catalysts active sites.Herein,operando high-energy resolution fluorescence-detected X-ray absorption spectroscopy was used to precisely identify the dynamic structural transformation of well-defined active sites of a representative model copper(Ⅱ)phthalocyanine catalyst which is of guiding significance in studying single-atom catalysis system.Comprehensive X-ray spectroscopy analyses,including surface sensitive△μspectra which isolates the surface changes by subtracting the disturb of bulk base and X-ray absorption near-edge structure spectroscopy simulation,were used to discover that Cu species aggregated with increasing applied potential,which is responsible for the observed evolution of C_(2)H_(4).The approach developed in this work,characterizing the active-site geometry and dynamic structural change,is a novel and powerful technique to elucidate complex catalytic mechanisms and is expected to con tribute to the rational design of highly effective catalysts. | Bingbao Mei Cong Liu Ji Li Songqi Gu Xianlong Du Siyu Lu Fei Song Weilin Xu Zheng Jiang | 2022 | Journal of Energy Chemistry2022，31，1： | 3 |
| 16 | Standard pancreatoduodenectomy versus extended pancreatoduodenectomy with modified retroperitoneal nerve resection in patients with pancreatic head cancer:a multicenter randomized controlled trial显示文摘Background:The extent of pancreatoduodenectomy for pancreatic head cancer remains controversial,and more high-level clinical evidence is needed.This study aimed to evaluate the outcome of extended pancreatoduodenectomy(EPD)with retroperitoneal nerve resection in pancreatic head cancer.Methods:This multicenter randomized trial was performed at 6 Chinese highvolume hospitals that enrolled patients between October 3,2012,and September 21,2017.Four hundred patients with stage I or II pancreatic head cancer and without specific pancreatic cancer treatments(preoperative chemotherapy or chemoradiation)within three months were randomly assigned to undergo standard pancreatoduodenectomy(SPD)or EPD,with the latter followed by dissection of additional lymph nodes(LNs),nerves and soft tissues 270◦on the right side surrounding the superior mesenteric artery and celiac axis.The primary endpoint was overall survival(OS)by intention-to-treat(ITT).The secondary endpoints were disease-free survival(DFS),mortality,morbidity,and postoperative pain intensity.Results:TheR1 ratewas slightly lower with EPD(8.46%)thanwith SPD(12.56%).The morbidity and mortality rates were similar between the two groups.The median OS was similar in the EPD and SPD groups by ITT in the whole study cohort(23.0 vs.20.2 months,P=0.100),while the median DFS was superior in the EPD group(16.1 vs.13.2 months,P=0.031).Patients with preoperative CA19–9<200.0 U/mL had significantly improved OS and DFS with EPD(EPD vs.SPD,30.8 vs.20.9 months,P=0.009;23.4 vs.13.5 months,P<0.001).The EPD group exhibited significantly lower locoregional(16.48%vs.35.20%,P<0.001)andmesenteric LNrecurrence rates(3.98%vs.10.06%,P=0.022).The EPD group exhibited less back pain 6 months postoperation than the SPD group.Conclusions:EPD for pancreatic head cancer did not significantly improve OS,but patients with EPD treatment had significantly improved DFS.In the subgroup analysis,improvements in bothOS and DFS in the EPD armwere observed in patients with preoperative CA19–9<200.0 U/mL.EPD could be used as an effective surgical procedure for patients with pancreatic head cancer,especially those with preoperative CA19–9<200.0 U/mL. | Qing Lin Shangyou Zheng Xianjun Yu Meifu Chen Yu Zhou Quanbo Zhou Chonghui Hu Jing Gu Zhongdong Xu LinWang Yimin Liu Qingyu Liu MinWang Guolin Li He Cheng Dongkai Zhou Guodong Liu Zhiqiang Fu Yu Long Yixiong Li Weilin Wang Renyi Qin Zhihua Li Rufu Chen | 2023 | Cancer Communications2023，43，2： | 3 |

| 18 | Single-Molecule Kinetics of Nanoparticle Catalysis显示文摘Owing to their structural dispersion,the catalytic properties of nanoparticles are challenging to characterize in ensemble-averaged measurements.The single-molecule approach enables studying the catalysis of nanoparticles at the single-particle level with real-time single-turnover resolution.This article reviews our single-molecule fluorescence studies of single Au-nanoparticle catalysis,focusing on the theoretical formulations for extracting quantitative reaction kinetics from the single-turnover resolution catalysis trajectories.We discuss the single-molecule kinetic formulism of the Langmuir-Hinshelwood mechanism for heterogeneous catalysis,as well as of the two-pathway model for product dissociation reactions.This formulism enables the quantitative evaluation of the heterogeneous reactivity and the differential selectivity of individual nanoparticles that are usually hidden in ensemble measurements.Extension of this formulism to single-molecule catalytic kinetics of oligomeric enzymes is also discussed. | Weilin Xu Hao Shen Guokun Liu Peng Chen | 2009 | Nano Research2009，2，12： | 2 |

X-ray diffraction spectra of polycrystal powder are conformable with the JCPDS cards. Lattice constants a and c calculated from the XRD were found to obey Vegard's law. The melting point of AgGa0.8In0.2Se2 obtained by means of differential scanning calorimetry (DSC) is 796.53 ℃. The DSC curve also show that there are no other transformation points below the melting point. The results indicate that polycrystalline materials synthesized by the method mentioned above are high-quality and can be used to grow single crystals by the vertical Bridgman technology. | Liu Juan Zhao Beijun Zhu Shifu Huang Yi Zhang Jianjun Zhu Weilin Xu Chengfu Chen Baojun Li Ming He Zhiyu | 2006 | Journal of Rare Earths2006，24，z1： | 2 |
| 20 | Rabies Virus Pseudotyped with CVS-N2C Glycoprotein as a Powerful Tool for Retrograde Neuronal Network Tracing显示文摘Efficient viral vectors for mapping and manipulating long-projection neuronal circuits are crucial in structural and functional studies of the brain. The SAD strain rabies virus with the glycoprotein gene deleted pseudotyped with the N2 C glycoprotein(SAD-RV(DG)-N2 C(G)) shows strong neuro-tropism in cell culture, but its in vivo efficiency for retrograde gene transduction and neuro-tropism have not been systematically characterized.We compared these features in different mouse brain regions for SAD-RV-N2 C(G) and two other widely-used retrograde tracers, SAD-RV(DG)-B19(G) and r AAV2-retro. We found that SAD-RV(DG)-N2 C(G) enhanced the infection efficiency of long-projecting neurons by^10 times but with very similar neuro-tropism, compared with SAD-RV(DG)-B19(G). On the other hand, SAD-RV(DG)-N2 C(G) had an infection efficiency comparable with r AAV2-retro, but a more restricted diffusion range, and broader tropism to different types and regions of longprojecting neuronal populations. These results demonstrate that SAD-RV(DG)-N2 C(G) can serve as an effective retrograde vector for studying neuronal circuits. | Xutao Zhu Kunzhang Lin Qing Liu Xinpei Yue Huijie Mi Xiaoping Huang Xiaobin He Ruiqi Wu Danhao Zheng Dong Wei Liangliang Jia Weilin Wang Anne Manyande Jie Wang Zhijian Zhang Fuqiang Xu | 2020 | Neuroscience Bulletin2020，36，3： | 2 |
