| 3 | Cidea controls lipid droplet fusion and lipid storage in brown and white adipose tissue显示文摘Excess lipid storage in adipose tissue results in the development of obesity and other metabolic disorders including diabetes,fatty liver and cardiovascular diseases.The lipid droplet(LD)is an important subcellular organelle responsible for lipid storage.We previously observed that Fsp27,a member of the CIDE family proteins,is localized to LD-contact sites and promotes atypical LD fusion and growth.Cidea,a close homolog of Fsp27,is expressed at high levels in brown adipose tissue.However,the exact role of Cidea in promoting LD fusion and lipid storage in adipose tissue remains unknown.Here,we expressed Cidea in Fsp27-knockdown adipocytes and observed that Cidea has similar activity to Fsp27 in promoting lipid storage and LD fusion and growth.Next,we generated Cidea and Fsp27 double-deficient mice and observed that these animals had drastically reduced adipose tissue mass and a strong lean phenotype.In addition,Cidea/Fsp27 double-deficient mice had improved insulin sensitivity and were intolerant to cold.Furthermore,we observed that the brown and white adipose tissues of Cidea/Fsp27double-deficient mice had significantly reduced lipid storage and contained smaller LDs compared to those of Cidea or Fsp27single deficient mice.Overall,these data reveal an important role of Cidea in controlling lipid droplet fusion,lipid storage in brown and white adipose tissue,and the development of obesity. | WU LiZhen ZHOU LinKang CHEN Cheng GONG JingYi XU Li YE Jing LI De LI Peng | 2014 | Science China(Life Sciences)2014，57，1： | 11 |

| 7 | Effects of dietary supplementation with essential oils and protease on growth performance,antioxidation,inflammation and intestinal function of weaned pigs显示文摘This experiment evaluated the impacts of essential oils(EO)and protease(PRO),independently or in combination,on growth performance,antioxidation,inflammation and intestinal function of weaned pigs.One hundred and sixty weaned pigs(21 d of age,BW of 6.74±0.20 kg)were randomly divided into 4 treatments with 8 replicate pens of 5 pigs per pen.Dietary treatments included the following:1)control diet(CON),2)CON with 300 mg/kg essential oils(EO),3)CON with 500 mg/kg protease(PRO),4)CON with 300 mg/kg essential oil and 500 mg/kg protease(EO + PRO).On d 8,one pig from each penwas selected for sampling.The remaining pigs were fed for an additional week and growth performance was monitored during this period.Dietary treatments had no marked effects(P>0.05)on the growth performance of pigs.However,pigs receiving EO diet had higher(P<0.05)serumglutathione peroxidase(GSH-Px)activity,and tended to decrease(P=0.063)serum concentration of tumor necrosis factor-a(TNF-a).In addition,pigs receiving EO diet had higher(P<0.05)abundances of phylum Actinobacteria,and genera Bifidobacterium,and lower(P<0.05)phylum Bacteroidetes and genera Alloprevotella in colonic digesta.Pigs receiving PRO diet decreased(P<0.05)the serum concentration of malondialdehyde(MDA)and diamine oxidase activity,increased(P<0.05)the villus height and the ratio of villus height to crypt depth in duodenum,increased sucrase activity in jejunal mucosa,and also increased the abundance of phylum Actinobacteria in colonic digesta.Furthermore,the synergistic effects of EO and PROwas observed(P<0.05)for pigs with decreasing serum TNF-a concentration and increasing serum GSH-Px activity.Collectively,the results indicated that dietary supplementation of EO and PRO had no significant effects on growth performance of weaned pigs.EO diet appeared to improve antioxidant activity and intestinal microbiota,while PRO diet improved intestinal morphology and digestive enzyme activity,and there was a synergistic effect of EO and PRO on reducing inflammatory parameters in weaned pigs. | Xie Peng Qiang Zhou Cheng Wu Jian Zhao Quan Tan Ying He Liang Hu Zhengfeng Fang Yan Lin Shengyu Xu Bin Feng Jian Li Yong Zhuo Chris Van Ginneken Xuemei Jiang De Wu Lianqiang Che | 2022 | Animal Nutrition2022，，2： | 8 |
| 8 | Q-switching of waveguide lasers based on graphene/WS_2 van der Waals heterostructure显示文摘We report on the operation of passively Q-switched waveguide lasers at 1 μm wavelength based on a graphene∕WS_2 heterostructure as a saturable absorber(SA). The gain medium is a crystalline Nd:YVO_4 cladding waveguide produced by femtosecond laser writing. The nanosecond waveguide laser operation at 1064 nm has been realized with the maximum average output power of 275 m W and slope efficiency of 37%. In comparison with the systems based on single WS_2 or graphene SA, the lasing Q-switched by a graphene∕WS_2 heterostructure SA possesses advantages of a higher pulse energy and enhanced slope efficiency, indicating the promisingapplications of van der Waals heterostructures for ultrafast photonic devices. | ZIQI LI CHEN CHENG NINGNING DONG CAROLINA ROMERO QINGMING LU JUN WANG JAVIER RODRíGUEZ VáZQUEZ DE ALDANA YANG TAN FENG CHEN | 2017 | Photonics Research2017，5，5： | 7 |

| 10 | Establishment of a Predictive Diagnostic Model for Acute Mycoplasma Pneumoniae Infection in Elderly Patients with Community-acquired Pneumonia显示文摘We established a diagnostic model to predict acute Mycoplasma pneumoniae(M.pneumonia)infection in elderly Community-acquired pneumonia(CAP)patients.We divided 456 patients into acute and non-acute M.pneumoniae infection groups.Binary logistic regression and receiver operating characteristic(ROC)curves were used to establish a predictive model.The following independent factors were identified:age≥70 years;serum c TNT level≥0.05 ng/m L;lobar consolidation;mediastinal lymphadenopathy;and antibody titer in the acute phase≥1:40.The area under the ROC curve of the model was 0.923 and a score of≥7score predicted acute M.pneumoniae infection in elderly patients with CAP.The predictive model developed in this study has high diagnostic accuracy for the identification of elderly acute M.pneumoniae infection. | XiAO Hong Li XIN De Li WANG Yan CUI Li Jian LIU Xiao Ya LIU Song SONG Li Hong LIU Chun Ling YIN Cheng Hong | 2017 | Biomedical and Environmental Sciences2017，30，7： | 6 |
| 11 | Size, phase-controlled synthesis,the nucleation and growth mechanisms of NaYF_4:Yb/Er nanocrystals显示文摘Near-monodisperse NaYF_4:Yb/Er nanoparticles(NPs) with controlled size, phases(α,β) and shapes(sphere, and hexagonal plate) were synthesized by adjusting the NaF to RE(RE = Y, Yb, Er) ratios, the reaction temperature and time in the hot surfactant solutions(oleic acid, 1-octadecene) from the improved one-pot thermal decomposition metal trifluoroacetate, and the precursors were prepared via hydrothermal route. The growth kinetics of β-NaYF4 NPs includes several stages: nucleation, growth of aNaYF4, Ostwald ripening, size shrinkage and growth. The results prove that the temperatures are preferred to the phase transformation compared with the NaF content when other experimental conditions are unchanged. Our work will further facilitate the comprehension of the nucleation and growth mechanisms of the NPs, and provide guidance for their controlled synthesis. | Songtao Liu Gejihu De Yueshan Xu Xian Wang Yuanyuan Liu Chunyan Cheng Jianxun Wang | 2018 | Journal of Rare Earths2018，36，10： | 6 |
| 12 | Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis显示文摘BACKGROUND For palliation of malignant biliary obstruction(MBO), the gold-standard method of biliary drainage is endoscopic retrograde cholangiopancreatography(ERCP)with the placement of metallic stents. Endoscopic ultrasound(EUS)-guided drainage is an alternative that is typically reserved for cases of ERCP failure.Recently, however, there have been robust randomized clinical trials(RCTs)comparing EUS-guided drainage and ERCP as primary approaches to MBO.AIM To compare EUS guidance and ERCP in terms of their effectiveness and safety in palliative biliary drainage for MBO.METHODS This was a systematic review and meta-analysis, in which we searched the MEDLINE, Excerpta Medica, and Cochrane Central Register of Controlled Trials databases. Only RCTs comparing EUS and ERCP for primary drainage of MBO were eligible. All of the studies selected provided data regarding the rates of technical and clinical success, as well as the duration of the procedure, adverse events, and stent patency. We assessed the risk of biases using the Jadad score and the quality of evidence using the Grading of Recommendations Assessment,Development and Evaluation criteria.RESULTS The database searches yielded 5920 records, from which we selected 3 RCTs involving a total of 222 patients(112 submitted to EUS and 110 submitted to ERCP). In the EUS and ERCP groups, the rate of technical success was 91.96%n and 91.81%, respectively, with a risk difference(RD) of 0.00%(95%CI:-0.07, 0.07;P = 0.97; I^2 = 0%). The clinical success was 84.81% and 85.53% in the EUS and ERCP groups, respectively, with an RD of-0.01%(95%CI:-0.12, 0.10; P = 0.90; I^2 =0%). The mean difference(MD) for the duration of the procedure was-0.12%(95%CI:-8.20, 7.97; P = 0.98; I^2 = 84%). In the EUS and ERCP groups, there were14 and 25 adverse events, respectively, with an RD of-0.06%(95%CI:-0.23, 0.12; P= 0.54; I^2 = 77%). The MD for stent patency was 9.32%(95%CI:-4.53, 23.18; P =0.19; I^2 = 44%). The stent dysfunction rate was significantly lower in the EUS t group(MD =-0.22%; 95 CI:-0.35,-0.08; P = 0.001; I^2 = 0%).CONCLUSION EUS represents an interesting alternative to ERCP for MBO drainage,demonstrating lower stent dysfunction rates compared with ERCP. Technical and clinical success, duration, adverse events and patency rates were similar. | Fernanda P Logiudice Wanderlei M Bernardo Facundo Galetti Vitor M Sagae Carolina O Matsubayashi Antonio C Madruga Neto Vitor O Brunaldi Diogo T H de Moura Tomazo Franzini Spencer Cheng Sergio E Matuguma Eduardo G H de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，4： | 6 |

| 17 | Exhumation history of the Huangshan granite pluton,southern Anhui Province:New insights from fission-track analysis显示文摘The dating of the uplift onset of the Huangshan pluton in the southern part of Anhui Province associated with the collision between paleo-Pacific Block and the Eurasian Block is a fundamental issue to better understand the uplift mechanisms and the regional tectonic evolution.χ2 values of seven zircon fission track(ZFT) samples collected from the south part of the Huangshan pluton were all<5%.Based on the grain ages of four typical ZFT samples,three thermal overprints ranging in 113-123,72-95 and 49-66 Ma were distinguished respectively using the binomial peak-fitting method in accordance with the tectonic thermal events after south China shifted into circum-Pacific tectonic region.Apatite fission track(AFT) study of the Huangshan pluton shows ages lie between 15±3 and 56±6 Ma with allχ2 values>5%,and all are significantly younger than their host rock formation ages,indicating that the samples have experienced post-formation thermal history.Based on the AFT results and topography characteristics in the Huangshan pluton,three zones with different denudation intensities caused by the differential uplift of the fault blocks were recognized in this paper,indicating that denudation was driven by the increase in elevation significantly.Modeling of the AFT data shows that the earlier cooling phase took place in the early Cenozoic and involved 3.3,3.8 and 6.0°C/Ma of cooling rates equivalent to the exhumation rates of 90,104 and 167 m/Ma in different fault blocks.The last phase of cooling took place from~10 Ma with average cooling rate of~5.6°C/Ma,equivalent to average denudation rates of~156 m/Ma.The fission track results imply that the regional compression field plays an important role for the differential exhumation between individual fault blocks of the Huangshan pluton. | ZHENG Yong YU XinQi YUAN WanMing WANG De'En JIANG GongBing ZHU DeLai WANG Cheng JIA YingYing | 2011 | Science China Earth Sciences2011，54，4： | 3 |
| 18 | Haplotype-resolved genome assembly and allele- specific gene expression in cultivated ginger显示文摘Ginger(Zingiber officinale)is one of the most valued spice plants worldwide;it is prized for its culinary and folk medicinal applications and is therefore of high economic and cultural importance.Here,we present a haplotype-resolved,chromosome-scale assembly for diploid ginger anchored to 11 pseudochromosome pairs with a total length of 3.1 Gb.Remarkable structural variation was identified between haplotypes,and two inversions larger than 15Mb on chromosome 4 may be associated with ginger infertility.We performed a comprehensive,spatiotemporal,genome-wide analysis of allelic expression patterns,revealing that most alleles are coordinately expressed.The alleles that exhibited the largest differences in expression showed closer proximity to transposable elements,greater coding sequence divergence,more relaxed selection pressure,and more transcription factor binding site differences.We also predicted the transcription factors potentially regulating 6-gingerol biosynthesis.Our allele-aware assembly provides a powerful platform for future functional genomics,molecular breeding,and genome editing in ginger. | Shi-Ping Cheng Kai-Hua Jia Hui Liu Ren-Gang Zhang Zhi-Chao Li Shan-Shan Zhou Tian-Le Shi Ai-Chu Ma Cong-Wen Yu Chan Gao Guang-Lei Cao Wei Zhao Shuai Nie Jing-Fang Guo Si-Qian Jiao Xue-Chan Tian Xue-Mei Yan Yu-Tao Bao Quan-Zheng Yun Xin-Zhu Wang Ilga Porth Yousry AEl-Kassaby Xiao-Ru Wang Zhen Li Yves Van de Peer Jian-Feng Mao | 2021 | Horticulture Research2021，8，1： | 3 |
| 19 | Role of pancreatography in the endoscopic management of encapsulated pancreatic collections-review and new proposed classification显示文摘Pancreatic fluids collections are local complications related to acute or chronic pancreatitis and may require intervention when symptomatic and/or complicated.Within the last decade,endoscopic management of these collections via endoscopic ultrasound-guided transmural drainage has become the gold standard treatment for encapsulated pancreatic collections with high clinical success and lower morbidity compared to traditional surgery and percutaneous drainage.Proper understanding of anatomic landmarks,including assessment of the main pancreatic duct and any associated lesions–such as disruptions and strictures-are key to achieving clinical success,reducing the need for reintervention or recurrence,especially in cases with suspected disconnected pancreatic duct syndrome.Additionally,proper review of imaging and anatomic landmarks,including collection location,are pivotal to determine type and size of pancreatic stenting as well as approach using long-term transmural indwelling plastic stents.Pancreatography to adequately assess the main pancreatic duct may be performed by two methods:Either non-invasively using magnetic resonance cholangiopancreatography or endoscopically via retrograde cholangiopancreatography.Despite the critical need to understand anatomy via pancrea tography and assess the main pancreatic duct,a standardized approach or uniform assessment strategy has not been described in the literature.Therefore,the aim of this review was to clarify the role of pancreatography in the endoscopic management of encapsulated pancreatic collections and to propose a new classification system to aid in proper assessment and endoscopic treatment. | Igor Mendonca Proença Marcos Eduardo Lera dos Santos Diogo Turiani Hourneaux de Moura Igor Braga Ribeiro Sergio Eiji Matuguma Spencer Cheng Thomas R McCarty Epifanio Silvino do Monte Junior Paulo Sakai Eduardo Guimaraes Hourneaux de Moura | 2020 | World Journal of Gastroenterology2020，26，45： | 3 |
| 20 | Seismic stability of loess tunnels under the effects of rain seepage and a train load显示文摘Loess tunnels are widely used in transportation engineering and are irreplaceable parts of transportation infrastructure. In this paper, a dynamic finite element method is used to analyze the coupled effects of a train vibration load and rainfall seepage. By calculating the variation in the safety factor of a loess tunnel because of the effects of various factors, such as different rainfall intensities and soil thicknesses, the dynamic stability of the loess tunnel is studied under the condition of a near-field pulse-like earthquake. The results show that the security and stability of the tunnel decrease gradually with decreasing burial depth. In addition, the plastic strain of the tunnel is mainly distributed on both sides of the vault and the feet, and the maximum value of the critical strain occurs on both sides of the arch feet. Because of the effects of the train vibration load and rainfall seepage, the safety factor of the loess tunnel structure decreases to a certain degree. Moreover, the range and maximum value of the plastic strain increase to various degrees. | CHENG XuanSheng MA Liang YU DongPo FAN Jin LI De | 2018 | Science China(Technological Sciences)2018，61，5： | 3 |
