| 1 | Organochlorine compounds and polycyclic aromatic hydrocarbons in surface sediment from Baiyangdian Lake,North China:Concentrations,sources profiles and potential risk显示文摘Organochlorine pesticides(OCPs),polychlorinated biphenyls(PCBs),and polycyclic aromatic hydrocarbons(PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river(Fuhe River) in North China.Total concentrations of OCPs,PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g,2.3 to 197.8 ng/g,and 101.3 to 6360.5 ng/g,respectively.The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake.For hexachlorocyclohexane(HCHs) and dichlorodiphenytrichloroethanes(DDTs),α-HCH and p,p-DDT were predominant isomers;while for PCBs,PCB 28/31,PCB 40/103,PCB 60,PCB 101,and PCB 118 were predominant congeners.Possible sources derived from historical usage for OCPs and incomplete combustion fuel,wood,and coal and exhaustion of boats or cars for PAHs.Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact. | Guocheng Hu Xiaojun Luo Fengchao Li Jiayin Dai Jianyang Guo Shejun Chen Cao Hong Bixian Mai Muqi Xu | 2010 | Journal of Environmental Sciences2010，22，2： | 42 |
| 2 | Seismic Sequence in Carbonate Rocks By Vibrational Liquefaction显示文摘On the basis of the records of strong seismic events taking place in soft carbonate sediments, a new seismic sequence system of vibrational liquefaction is established, which consists of a series of units, such as escaped structure of micrite veins and liquefied deformation formed in the period of seismic liquefaction, land subsidence structure after liquefaction, tsunamic hummocky and turbidite produced by seismic events, This sequence is a generalization and summation of field observation in vast areas, which shows the whole process of a strong seismic event and provides an unified theoretical explanation. The pattern of the seismic sequence by vibrational liquefaction provides one of correlation standards for geologists in the field to discriminate events in carbonate sequences. Based on the pattern of seismic sequence, the authors first advance a new conception of the Palaeo-Tanlu (Tancheng-Lujiang) Zone and discuss primarily its geological significations. | Qiao Xiufu, Song Tianrui, Gao Linzhi, Peng Yang, Li Haibing, Gao Mai, Song Biao and Zhang QiaodaInstitute of Geology, Chinese Academy of Geological Sciences, Beijing | 1994 | Acta Geologica Sinica(English Edition)1994，68，3： | 39 |
| 3 | Roux-en-Y versus BillrothⅠreconstruction after distal gastrectomy for gastric cancer:A meta-analysis显示文摘AIM:To conduct a meta-analysis to compare Rouxen-Y(R-Y) gastrojejunostomy with gastroduodenal Billroth Ⅰ(B-Ⅰ) anastomosis after distal gastrectomy(DG) for gastric cancer.METHODS:A literature search was performed to identify studies comparing R-Y with B-Ⅰ after DG for gastric cancer from January 1990 to November 2012 in Medline,Embase,Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in The Cochrane Library.Pooled odds ratios(OR) or weighted mean differences(WMD) with 95%CI were calculated using either fixed or random effects model.Operative outcomes such as operation time,intraoperative blood loss and postoperative outcomes such as anastomotic leakage and stricture,bile reflux,remnant gastritis,reflux esophagitis,dumping symptoms,delayed gastric emptying and hospital stay were the main outcomes assessed.Meta-analyses were performed using RevMan 5.0 software(Cochrane library).RESULTS:Four randomized controlled trials(RCTs) and 9 non-randomized observational clinical studies(OCS) involving 478 and 1402 patients respectively were included.Meta-analysis of RCTs revealed that R-Y reconstruction was associated with a reduced bile reflux(OR 0.04,95%CI:0.01,0.14;P < 0.00 001) and remnant gastritis(OR 0.43,95%CI:0.28,0.66;P = 0.0001),however needing a longer operation time(WMD 40.02,95%CI:13.93,66.11;P = 0.003).Metaanalysis of OCS also revealed R-Y reconstruction had a lower incidence of bile reflux(OR 0.21,95%CI:0.08,0.54;P = 0.001),remnant gastritis(OR 0.18,95%CI:0.11,0.29;P < 0.00 001) and reflux esophagitis(OR 0.48,95%CI:0.26,0.89;P = 0.02).However,this reconstruction method was found to be associated with a longer operation time(WMD 31.30,95%CI:12.99,49.60;P = 0.0008).CONCLUSION:This systematic review point towards some clinical advantages that are rendered by R-Y compared to B-Ⅰ reconstruction post DG.However there is a need for further adequately powered,welldesigned RCTs comparing the same. | Jun-Jie Xiong Kiran Altaf Muhammad A Javed Quentin M Nunes Wei Huang Gang Mai Chun-Lu Tan Rajarshi Mukherjee Robert Sutton Wei-Ming Hu Xu-Bao Liu | 2013 | World Journal of Gastroenterology2013，19，7： | 33 |

| 6 | Meta-analysis of laparoscopic vs open liver resection for hepatocellular carcinoma显示文摘AIM:To conduct a meta-analysis to determine the safety and efficacy of laparoscopic liver resection(LLR) and open liver resection(OLR) for hepatocellular carcinoma(HCC).METHODS:PubMed(Medline),EMBASE and Science Citation Index Expanded and Cochrane Central Register of Controlled Trials in the Cochrane Library were searched systematically to identify relevant comparative studies reporting outcomes for both LLR and OLR for HCC between January 1992 and February 2012.Two authors independently assessed the trials for inclusion and extracted the data.Meta-analysis was performed using Review Manager Version 5.0 software(The Cochrane Collaboration,Oxford,United Kingdom).Pooled odds ratios(OR) or weighted mean differences(WMD) with 95%CI were calculated using either fixed effects(Mantel-Haenszel method) or random effects models(DerSimonian and Laird method).Evaluated endpoints were operative outcomes(operation time,intraoperative blood loss,blood transfusion requirement),postoperative outcomes(liver failure,cirrhotic decompensation/ascites,bile leakage,postoperative bleeding,pulmonary complications,intraabdominal abscess,mortality,hospital stay and oncologic outcomes(positive resection margins and tumor recurrence).RESULTS:Fifteen eligible non-randomized studies were identified,out of which,9 high-quality studies involving 550 patients were included,with 234 patients in the LLR group and 316 patients in the OLR group.LLR was associated with significantly lower intraoperative blood loss,based on six studies with 333 patients [WMD:-129.48 mL;95%CI:-224.76-(-34.21) mL;P = 0.008].Seven studies involving 416 patients were included to assess blood transfusion requirement between the two groups.The LLR group had lower blood transfusion requirement(OR:0.49;95%CI:0.26-0.91;P = 0.02).While analyzing hospital stay,six studies with 333 patients were included.Patients in the LLR group were found to have shorter hospital stay [WMD:-3.19 d;95%CI:-4.09-(-2.28) d;P < 0.00001] than their OLR counterpart.Seven studies including 416 patients were pooled together to estimate the odds of developing postoperative ascites in the patient groups.The LLR group appeared to have a lower incidence of postoperative ascites(OR:0.32;95%CI:0.16-0.61;P = 0.0006) as compared with OLR patients.Similarly,fewer patients had liver failure in the LLR group than in the OLR group(OR:0.15;95%CI:0.02-0.95;P =0.04).However,no significant differences were found between the two approaches with regards to operation time [WMD:4.69 min;95%CI:-22.62-32 min;P = 0.74],bile leakage(OR:0.55;95%CI:0.10-3.12;P = 0.50),postoperative bleeding(OR:0.54;95%CI:0.20-1.45;P = 0.22),pulmonary complications(OR:0.43;95%CI:0.18-1.04;P = 0.06),intra-abdominal abscesses(OR:0.21;95%CI:0.01-4.53;P = 0.32),mortality(OR:0.46;95%CI:0.14-1.51;P = 0.20),presence of positive resection margins(OR:0.59;95%CI:0.21-1.62;P = 0.31) and tumor recurrence(OR:0.95;95%CI:0.62-1.46;P = 0.81).CONCLUSION:LLR appears to be a safe and feasible option for resection of HCC in selected patients based on current evidence.However,further appropriately designed randomized controlled trials should be undertaken to ascertain these findings. | Jun-Jie Xiong Kiran Altaf Muhammad A Javed Wei Huang Rajarshi Mukherjee Gang Mai Robert Sutton Xu-Bao Liu Wei-Ming Hu | 2012 | World Journal of Gastroenterology2012，18，45： | 25 |
| 7 | Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective. | Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai | 2017 | Chinese Journal of Cancer2017，36，8： | 25 |
| 8 | Prevalence and risk factors of gallbladder polypoid lesions in Chinese petrochemical employees显示文摘AIM:To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China. METHODS:All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invitedto have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted. RESULTS:A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of postcholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P < 0.001). The analyzed risk factors with increased OR for the development of PLGs were male gender (OR = 1.799, P < 0.001), age ≥ 30 years (OR = 2.699, P < 0.001) and hepatitis B surface antigen (HBsAg) positivity (OR = 1.374, P = 0.006). CONCLUSION:PLGs are not rare among Chinese petrochemical employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs. | Yu-Shan Mao Yi-Feng Mai Fu-Jun Li Yan-Ming Zhang Ke-Min Hu Zhong-Li Hong Zhong-Wei Zhu | 2013 | World Journal of Gastroenterology2013，19，27： | 23 |
| 9 | Soil Organic Carbon Content and Distribution in a Small Landscape of Dongguan, South China显示文摘Global warming has become an increasing concern, and using soil as a carbon sink to sequester carbon dioxide has attracted much attention in recent years. In this study, soil organic carbon (SOC) content and organic carbon density were estimated based on a soil survey of a small landscape in Dongguan, South China, with spatial heterogeneity of SOC distribution and the impacts of land-use patterns on soil organic carbon content assessed. Field sampling was carried out based on a 150 m×150 m grid system overlaid on the topographic map of the study area and samples were collected in three 20-cm layers to a depth of 60 cm. Spatial variability in the distribution of SOC was assessed using the Kruskal-Wallis test. Results showed that SOC in the topsoil layer (0-20 cm) was not much higher or even lower in some sites than the underlying layers, and except for the two sites covered with natural woodland, it did not exhibit a pronounced vertical gradient. The difference in both horizontal and vertical distribution of SOC was not statistically significant. However, in the topsoil layer among land-use/land-cover patterns, significant differences (P≤0.05) in SOC distribution existed, indicating that management practices had great impact on SOC content. SOC storage in the study area to a depth of 20, 40, and 60 cm was estimated as 2.13×106 kg, 3.46×106 kg, and 4.61×106 kg, respectively. | SU Zhi-Yao XIONG Yong-Mei ZHU Jian-Yun YE Yong-Chang YE Mai | 2006 | Pedosphere2006，16，1： | 22 |

| 12 | Recent advances and remaining gaps in our knowledge of associations between gut microbiota and human health显示文摘The complex gut microbial flora harbored by individuals(microbiota) has long been proposed to contribute tointestinal health as well as disease. Pre-and probioticproducts aimed at improving health by modifyingmicrobiota composition have already become widelyavailable and acceptance of these products appearsto be on the rise. However, although required forthe development of effective microbiota basedinterventions, our basic understanding of microbiotavariation on a population level and its dynamics withinindividuals is still rudimentary. Powerful new parallelsequence technologies combined with other efficientmolecular microbiota analysis methods now allow forcomprehensive analysis of microbiota composition inlarge human populations. Recent fi ndings in the fi eldstrongly suggest that microbiota contributes to thedevelopment of obesity, atopic diseases, inflammatorybowel diseases and intestinal cancers. Through theongoing National Institutes of Health Roadmap 'HumanMicrobiome Project' and similar projects in other partsof the world, a large coordinated effort is currentlyunderway to study how microbiota can impact humanhealth. Translating findings from these studies intoeffective interventions that can improve health,possibly personalized based on an individuals existingmicrobiota, will be the task for the next decade(s). | Volker Mai Peter V Draganov | 2009 | World Journal of Gastroenterology2009，15，1： | 21 |
| 13 | 腰椎皮质骨椎弓根螺钉与传统椎弓根钉置钉点骨密度差异之比较显示文摘椎弓根螺钉目前广泛应用于治疗各种腰椎疾患,尽管其在重建腰椎稳定性方面优势非常明显,但螺钉松动、移位、拔出等并发症时有发生,不仅影响手术疗效,甚至还需要二次手术翻修。Santoni等于2009年提出皮质骨钉道(corticalbonetrajector,CBT)椎弓根螺钉(简称CBT螺钉)固定技术,其轴向拔出力较传统椎弓根螺钉平均提升30%,具有显露更少、切口更短、术后康复更快等优点。众所周知,骨密度(bonemineraldensity,BMD)与螺钉拔出力呈正相关。传统椎弓根螺钉末端常位于椎体中段松质骨内,随年龄增长,松质骨BMD下降,螺钉固定的风险增加并可最终导致螺钉松动。而CBT螺钉固定点位于椎弓根及椎体皮质骨中,理论上降低了螺钉松动的风险,即使是老年患者,其置钉位置的BMD也较传统椎弓根螺钉置入的椎体中部更能有效维持;而当获得与传统椎弓根螺钉相同或更好的机械稳定性时,CBT螺钉所需的长度也更短,这一点在骨量减少或骨质疏松患者的尸体研究中得到进一步证实。 | Mai HT Mitchell SM Hashmi SZ 胡玮 马向阳 | 2016 | 中国骨科临床与基础研究杂志2016，8，5： | 21 |

| 20 | Single-cell transcriptomic analysis defines the interplay between tumor cells,viral infection,and the microenvironment in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an Epstein-Barr virus(EBV)-associated malignancy with a complex tumor ecosystem.How the interplay between tumor cells,EBV,and the microenvironment contributes to NPC progression and immune evasion remains unclear.Here we performed single-cell RNA sequencing on^104,000 cells from 19 EBV^+NPCs and 7 nonmalignant nasopharyngeal biopsies,simultaneously profiling the transcriptomes of malignant cells,EBV,stromal and immune cells.Overall,we identified global upregulation of interferon responses in the multicellular ecosystem of NPC.Notably,an epithelial–immune dual feature of malignant cells was discovered and associated with poor prognosis.Functional experiments revealed that tumor cells with this dual feature exhibited a higher capacity for tumorigenesis.Further characterization of the cellular components of the tumor microenvironment(TME)and their interactions with tumor cells revealed that the dual feature of tumor cells was positively correlated with the expression of co-inhibitory receptors on CD8^+tumor-infiltrating T cells.In addition,tumor cells with the dual feature were found to repress IFN-γproduction by T cells,demonstrating their capacity for immune suppression.Our results provide new insights into the multicellular ecosystem of NPC and offer important clinical implications. | Shanzhao Jin Ruoyan Li Ming-Yuan Chen Chao Yu Lin-Quan Tang Yan-Min Liu Jiang-Ping Li Yi-Na Liu Yi-Ling Luo Yifan Zhao Yu Zhang Tian-Liang Xia Shang-Xin Liu Qi Liu Guan-Nan Wang Rui You Jing-Yun Peng Jiang Li Feng Han Jianwei Wang Qiu-Yan Chen Li Zhang Hai-Qiang Mai Benjamin E.Gewurz Bo Zhao Lawrence S.Young Qian Zhong Fan Bai Mu-Sheng Zeng | 2020 | Cell Research2020，30，11： | 16 |
