| 1 | Analysis of risk factors for postoperative pancreatic fistula following pancreaticoduodenectomy显示文摘AIM:To explore the morbidity and risk factors of postoperative pancreatic fistula(POPF)following pancreaticoduodenectomy.METHODS:The data from 196 consecutive patients who underwent pancreaticoduodenectomy,performed by different surgeons,in the General Hospital of the People’s Liberation Army between January 1st,2013and December 31st,2013 were retrospectively collected for analysis.The diagnoses of POPF and clinically relevant(CR)-POPF following pancreaticoduodenectomy were judged strictly by the International Study Group on Pancreatic Fistula Definition.Univariate analysis was performed to analyze the following factors:patient age,sex,body mass index(BMI),hypertension,diabetes mellitus,serum CA19-9 level,history of jaundice,serum albumin level,blood loss volume,pancreatic duct diameter,pylorus preserving pancreaticoduodenectomy,pancreatic drainage and pancreaticojejunostomy.Multivariate logistic regression analysis was used to determine the main independent risk factors for POPF.RESULTS:POPF occurred in 126(64.3%)of the patients,and the incidence of CR-POPF was 32.7%(64/196).Patient characteristics of age,sex,BMI,hypertension,diabetes mellitus,serum CA19-9 level,history of jaundice,serum albumin level,blood loss volume,pylorus preserving pancreaticoduodenectomy and pancreaticojejunostomy showed no statistical difference related to the morbidity of POPF or CR-POPF.Pancreatic duct diameter was found to be significantly correlated with POPF rates by univariate analysis and multivariate regression analysis,with a pancreatic duct diameter≤3 mm being an independent risk factor for POPF(OR=0.291;P=0.000)and CR-POPF(OR=0.399;P=0.004).The CR-POPF rate was higher in patients without external pancreatic stenting,which was found to be an independent risk factor for CR-POPF(OR=0.394;P=0.012).Among the entire patient series,there were three postoperative deaths,giving a total mortality rate of 1.5%(3/196),and the mortality associated with pancreatic fistula was 2.4%(3/126).CONCLUSION:A pancreatic duct diameter≤3 mm is an independent risk factor for POPF.External stent drainage of pancreatic secretion may reduce CR-POPF mortality and POPF severity. | Qi-Yu Liu Wen-Zhi Zhang Hong-Tian Xia Jian-Jun Leng Tao Wan Bin Liang Tao Yang Jia-Hong Dong | 2014 | World Journal of Gastroenterology2014，20，46： | 32 |

| 3 | Fundamental mechanisms and phenomena of clathrate hydrate nucleation显示文摘Insights into the mechanism of hydrate nucleation are of great significance for the development of hydrate-based technologies,hydrate relevant flow assurance,and the exploration of in situ natural gas hydrates.Compared with the thermodynamics of hydrate formation,understanding the nucleation mechanism is challenging and has drawn substantial attention in recent decades.In this paper,we attempt to give a comprehensive review of the recent progress of studies of clathrate hydrate nucleation.First,the existing hypotheses on the hydrate nucleation mechanism are introduced and discussed.Then,we summarize recent experimental studies on induction time,a key parameter evaluating the velocity of the nucleation process.Subsequently,the memory effect is particularly discussed,followed by the suggestion of several promising research perspectives. | Jinlong Cui Zhenfeng Sun Xiaohui Wang Bin Yu Shudong Leng Guangjin Chen Changyu Sun | 2019 | Chinese Journal of Chemical Engineering2019，27，9： | 11 |
| 4 | The status of exploitation techniques of natural gas hydrate显示文摘Natural gas hydrate(NGH)has been widely considered as an alternative form of energy with huge potential,due to its tremendous reserves,cleanness and high energy density.Several countries involving Japan,Canada,India and China have launched national projects on the exploration and exploitation of gas hydrate resources.At the beginning of this century,an early trial production of hydrate resources was carried out in Mallik permafrost region,Canada.Japan has conducted the first field test from marine hydrates in 2013,followed by another trial in 2017.China also made its first trial production from marine hydrate sediments in 2017.Yet the low production efficiency,ice/hydrate regeneration,and sand problems are still commonly encountered;the worldwide progress is far before commercialization.Up to now,many gas production techniques have been proposed,and a few of them have been adopted in the field production tests.Nevertheless,hardly any method appears really promising;each of them shows limitations at certain conditions.Therefore,further efforts should be made on the economic efficiency as well as sustainability and environmental impacts.In this paper,the investigations on NGH exploitation techniques are comprehensively reviewed,involving depressurization,thermal stimulation,chemical inhibitor injection,CO2–CH4 exchange,their combinations,and some novel techniques.The behavior of each method and its further potential in the field test are discussed.The advantages and limitations of laboratory studies are also analyzed.The work could give some guidance in the future formulation of exploitation scheme and evaluation of gas production behavior from hydrate reservoirs. | Lei Yang Yulong Liu Hanquan Zhang Bo Xiao Xianwei Guo Rupeng Wei Lei Xu Lingjie Sun Bin Yu Shudong Leng Yanghui Li | 2019 | Chinese Journal of Chemical Engineering2019，27，9： | 9 |
| 5 | COMBINED EFFECT OF MODIFIED ZEOLITE 13X AND β-NUCLEATING AGENT ON IMPROVING β-CRYSTAL CONTENT AND TOUGHENING POLYPROPYLENE RANDOM COPOLYMER显示文摘Although addition of β-NUCLEATING agent directly into homo-polypropylene(PPH) is a useful method to improve β-CRYSTAL content and toughen PPH, polypropylene random copolymer(PPR) makes this method powerless due to its random structure and low crystallinity. In this study, the-nucleated PPR with high β-CRYSTAL content was prepared by a novel high effective β-NUCLEATING system which consists of-nucleation agent(TMB-5) and modified zeolite 13X(M13X). It was found that M13X and TMB-5 had a synergistic influence on improving β-CRYSTAL content and toughening PPR. The content of β-CRYSTAL in PPR/M13X/TMB-5 was significantly larger than the sum of that in PPR/M13X and PPR/TMB-5. Besides,fracture behavior, phase morphology and relaxation of matrix chain segments were also investigated. The results showed that M13X and TMB-5 improved the mobility of amorphous chain segments at low temperature and contributed to much energy dissipation. This work provides a powerful method to modify PPR. | Jin-hua Leng Heng Liu 何波兵 Bin Yang Xian Chen Qing-quan Qin | 2013 | Chinese Journal of Polymer Science2013，31，11： | 3 |
| 6 | Efficacy of Rebixiao Chinese herbal tablets and Chinese formula granules in acute gout arthritis patients:a randomized,multicenter,double-blind,controlled trial显示文摘OBJECTIVE:To evaluate the clinical efficacy and safety of Rebixiao(RBX)Chinese herbal tablets(CHT)and Chinese formula granules(CFG)in the treatment of acute gout arthritis(AGA).METHODS:This randomized,multicenter,double-blind,controlled trial included 165 AGA patients with the damp-heat symptom pattern who were randomly divided into an RBX CHT group and an RBX CFG group and treated for 7 d at three centers.The total effective rates of the joint symptom score,Traditional Chinese Medicine(TCM)symptoms score,erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP)were used to evaluate the clinical efficacy.Safety assessments were also performed.RESULTS:Of the 165 enrolled patients,147 completed the clinical observation.There was no difference in baseline between the two groups.The total effective rates of the joint symptom score were 94.36%and 97.36%,and the total effective rates of the TCM symptoms score were 95.77%and 97.36%in the CFG group and CHT group,respectively.No statistical difference was found between the two groups(P>0.05).Additionally,ESR and CRP were similar in both groups(P>0.05).Furthermore,treatment efficacy regarding TCM and joint symptoms,the ESR,and CRP were consistent within each center and among the different centers(P>0.05).In addition,the incidence of adverse events was 4.22%and 2.63%in the CFG group and CHT group,respectively,and no difference was observed between the two groups(P>0.05).CONCLUSION:RBX CFG and CHT have significant and similar efficacy in the treatment of AGA,and CFG did not increase adverse side effects. | Wang Shasha Zhang Ying Dai Min Yang Min Leng Wenfei Peng Xiufeng Li Guojun Yang Jinbing Gan Jianping Zhu Fenglin Li Yanping Wu Bin | 2020 | Journal of Traditional Chinese Medicine2020，40，4： | 3 |
| 7 | Advances in Research of Mineral Chemistry of Magmatic and Hydrothermal Biotites显示文摘Biotite is an important hydrated ferromagnesian silicate mineral in igneous rocks and porphyry deposits.The determination of chemical compositions of biotite plays an important role in both igneous petrology and ore forming processes.This paper summarizes research results of magmatic and hydrothermal biotites exemplified by the Lakange porphyry Cu–Mo deposit and the Qulong porphyry Cu deposit in the Gangdese porphyry–skarn metallogenic belt,Tibet.Biotite mineral chemistry can provide critical insights into classification,geothermometer,geothermobarometry,oxygen fugacity,petrogenesis and tectonic setting,evaluating magmatic-hydrothermal process by halogen and halogen fugacity ratios,and distinguishing between barren and mineralized rocks.Biotite provides the latest mineralogical evidence on metallogenic prognosis and prospecting evaluation for porphyry Cu polymetallic deposits or magmatic hydrothermal deposits. | TANG Pan CHEN Yuchuan TANG Juxing WANG Ying ZHENG Wenbao LENG Qiufeng LIN Bin WU Chunneng | 2019 | Acta Geologica Sinica(English Edition)2019，93，6： | 2 |
| 8 | A comparative study of proliferation and osteogenic differentiation of rat adipose-derived stem cells in β-tricalcium phosphate (β-TCP), forsterite (Mg_2SiO_4 ) and clinoenstatite (MgSiO_3)显示文摘In this study, the effects of forsterite and clinoenstatite powder extracts on the proliferation and osteogenic differentiation of rat adipose-derived stem cells (ASCs) were investigated and compared with the β-tricalcium phosphate (β-TCP) powder extracts. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and live-dead staining were performed to evaluate the viability and proliferation of rat ASCs. Osteogenic differentiation of rat ASCs were assayed by alkaline phosphatase (ALP) staining and ALP activity test. The expression of osteogenic marker genes (alkaline phosphatase (ALP), runt related transcription factor 2 (Runx2), collagen type Iα1 (Col1α1), secreted phosphoprotein1 (Spp1, osteopontin), integrin binding sialoprotein (Ibsp), bone gla protein (Bglap)) were detected by real-time polymerase chain reaction (PCR). The MTT assay and the live-dead staining showed that all the three ceramics possessed good cytocompatibility with rat ASCs. Furthermore, forsterite and clinoenstatite promoted the proliferation of rat ASCs compared with β-TCP. The results of the ALP activity test and the real-time PCR demonstrated that forsterite and clinoenstatite promoted the osteogenic differentiation of rat ASCs. These results suggested that forsterite and clinoenstatite are bioactive ceramics that may be used for preparation of bone tissue engineering (BTE) scaffolds. | LENG Bin JIN XiaoGang LIN QiuXia CHEN Lei WANG Yan DU ZhiYan LIN KaiLi CHANG Jiang GU XiaoMing WANG ChangYong | 2013 | Chinese Science Bulletin2013，58，24： | 2 |

| 15 | A complete assembly of the rice Nipponbare reference genome显示文摘Dear Editor,In 2005,the current commonly used rice reference genome(Oryza sativa ssp.japonica cv.Nipponbare)was initially released by the International Rice Genome Sequencing Project(International Rice Genome Sequencing Project,2005).Thereafter,the reference genome was further updated in 2013 with improved genome assembly(IRGSP-1.0)and gene annotations(MSU7,RAP-DB)(Kawahara et al.,2013;Sakai et al.,2013).In the past 10 years,this reference has been serving as one of the most important genetic resources for subsequent rice functional genomics efforts.As several rice genomes had been assembled into gapless chromosomes with only 2–5 telomeres absent(Li et al.,2021;Song et al.,2021;Zhang et al.,2022),the IRGSP1.0 and its annotations still performed as the most widely used reference.However,limitations of sequencing technology and intricate genomic organization led to an under-representation of complex regions in this reference,leaving a total of 72 major gaps(including 19 telomeres),167 minor gaps,and 779 unknown bases(Kawahara et al.,2013),with an estimated length of3%of the genome unsolved. | Lianguang Shang Wenchuang He Tianyi Wang Yingxue Yang Qiang Xu Xianjia Zhao Longbo Yang Hong Zhang Xiaoxia Li Yang Lv Wu Chen Shuo Cao Xianmeng Wang Bin Zhang Xiangpei Liu Xiaoman Yu Huiying He Hua Wei Yue Leng Chuanlin Shi Mingliang Guo Zhipeng Zhang Bintao Zhang Qiaoling Yuan Hongge Qian Xinglan Cao Yan Cui Qianqian Zhang Xiaofan Dai Congcong Liu Longbiao Guo Yongfeng Zhou Xiaoming Zheng Jue Ruan Zhukuan Cheng Weihua Pan Qian Qian | 2023 | Molecular Plant2023，16，8： | 1 |
