1利用洋底地震资料估算进入马里亚纳俯冲带的水通量显示文摘俯冲带水迁移是地表水进入地球深部的主要方式。但是,通过板块俯冲到底能够带入深部地幔多少水受到多种因素影响,包括俯冲带板片年龄、俯冲带几何性质、俯冲带热结构、板块汇聚速率等。目前关于俯;中带的水循环仍知之甚少。最近,华盛顿大学地球与行星科学系的Cai C博士等人收集和分析了马里亚纳海沟中心周围宽频洋底瑞利面波地震数据,估算了通过板块俯冲输入地球深部的水通量。他们的研究结果表明:板块俯冲带入深部地幔的水通量是以前估算的4.3倍,而且远大于目前对地幔输出水通量的估计。由于大量的长期净水流入地球深处与地质记录中的海平面稳定性不一致;同时也没有迹象表明马里亚纳俯冲带的板块弯曲区在形态和断裂强度与其它古俯冲带的对应区域对比有很大的不同。Cai C Wiens D A Shen W Eimer M 张宝华 2018矿物岩石地球化学通报2018,37,6:13
2Factors associated with 5-year survival of combined hepatocellular and cholangiocarcinoma显示文摘BACKGROUND Combined hepatocellular and cholangiocarcinoma(HCC/CC)is a rare primary hepatic malignancy which carries a poor prognosis due to its aggressive nature.Few centers have enough cases to draw definitive conclusions and there is limited understanding of prognosis.Given the rarity of HCC/CC,an analysis of large national cancer database was needed to obtain larger number of HCC/CC cases.AIM To identify associated factors for 5-year survival of HCC/CC.METHODS We conducted a retrospective study of The Surveillance,Epidemiology,and End Results(SEER)database obtained from SEER*Stat 8.3.6 software.Previously defined histology code 8180 for the International Classification of Disease for Oncology,3rd edition was used to identify HCC/CC cases from 2004 to 2015.We collected demographics,American Joint Committee on Cancer(AJCC)stage,treatment,tumor size,and survival data.These data were converted to categorical variables.The Shapiro-Wilk normality test was used to assess normal distribution.Mann-Whitney U test was used to compare continuous variables without normal distribution,and t-test was used to compare continuous variables with a normal distribution.The Kaplan-Meier survival curve analyzed 5-year survival.Univariate and multivariate logistic regression model was used to analyze factors associated with 5-year survival.Multivariate Cox proportional hazard regression was done on 5-year survival.We defined P<0.05 was statistically significant.RESULTS We identified 497 patients with the following characteristics:Mean age 62.4 years(SD:11.3),149(30.0%)were female,racial distribution was:276(55.5%)white,53(10.7%)black,84(16.9%)Asian and Pacific Islander(API),77(15.5%)Hispanic,and 7(1.4%)others or unknown.Stage I/II disease occurred in 41.5%and tumor size<50 mm was seen in 35.6%of patients.Twenty-four(4.8%)received locoregional therapy(LRT),119(23.9%)underwent resection,and 50(10.1%)underwent liver transplantation.The overall median survival was 6 mo[Interquartile range(IQR):1-22].After multivariate logistic regression,tumor size<50 mm[Odds ratios(OR):2.415,P=0.05],resection(OR:12.849,P<0.01),and transplant(OR:27.129,P<0.01)showed significance for 5-year survival.Age>60,sex,race,AJCC stages,metastasis,and LRT were not significant.However,API vs white showed significant OR of 2.793(CI:1.120-6.967).Cox proportional hazard regression showed AJCC stages,tumor size<50 mm,LRT,resection,and transplant showed significant hazard ratio.CONCLUSION HCC/CC patients with tumor size<50 mm,resection,and transplant were associated with an increase in 5-year survival.API showed advantageous OR and hazard ratios over white,black.Tomoki Sempokuya Eric A Wien Robert J Pattison Jihyun Ma Linda L Wong 2020World Journal of Hepatology2020,12,11:2
