| 1 | Comparison of hepatic venous pressure gradient and endoscopic grading of esophageal varices显示文摘AIM: To determine the correlation between the hepatic venous pressure gradient and the endoscopic grade of esophageal varices.METHODS: From September 2009 to March 2013, a total of 176 measurements of hepatic venous pressure gradient(HVPG) were done in 146 patients. Each transjugular HVPG was measured twice, first using an end whole catheter(EH-HVPG), and then using a balloon catheter(B-HVPG). The HVPG was compared with the endoscopic grade of esophageal varices(according to the general rules for recording endoscopic findings of esophagogastric varices), which was recorded within a month of the measurement of HVPG.RESULTS: The study included 110 men and 36 women, with a mean age of 56.1 years(range, 43-76 years). The technical success rate of the pressure measurements was 100% and there were no complication related to the procedures. Mean HVPG was 15.3 mm Hg as measured using the end hole catheter method and 16.5 mm Hg as measured using the balloon catheter method. Mean HVPG(both EHHVPG and B-HVPG) was not significantly different among patients with different characteristics, including sex and comorbid factors, except for cases with hepatocellular carcinoma(B-HVPG, P = 0.01; EH-HVPG, P = 0.02). Portal hypertension(> 12 mm Hg HVPG) occurred in 66% of patients according to EH-HVPG and 83% of patients according to B-HVGP, and significantly correlated with Child's status(B-HVPG, P < 0.000; EHHVGP, P < 0.000) and esophageal varies observed upon endoscopy(EH-HVGP, P = 0.003; B-HVGP, P = 0.006). One hundred and thirty-five endoscopies were performed, of which 15 showed normal findings, 27 showed grade 1 endoscopic esophageal varices, 49 showed grade 2 varices, and 44 showed grade 3 varices. When comparing endoscopic esophageal variceal grades and HVPG using univariate analysis, the P value was 0.004 for EH-HVPG and 0.002 for B-HVPG. CONCLUSION: Both EH-HVPG and B-HVPG showed a positive correlation with the endoscopic grade of esophageal varices, with B-HVPG showing a stronger correlation than EH-HVPG. | Eun Ji Lee Yong Jae Kim Dong Erk Goo Seung Boo Yang Hyun-Joo Kim Jae Young Jang Soung Won Jeong | 2016 | World Journal of Gastroenterology2016，22，11： | 11 |
| 2 | Removal of heavy metals using waste eggshell显示文摘由再使用的蛋壳的有毒的重金属的移动能力被学习。作为为从废物蛋壳的再使用的材料的准备的一个预告的处理过程,锻烧在压碎弄干的废物蛋壳以后为 2 h 在 800 ° C 在炉子被执行。在蛋壳的锻烧前后的锻烧行为,质、量的元素的信息,矿物质类型和表面特征被热 gravimetric 检验分析(TGA ) , X 光检查荧光(XRF ) , X 光检查衍射(XRD ) 和扫描电子显微镜学(SEM ) 分别地。在锻烧以后,主要无机的作文作为 Ca 被识别(石灰, 99.63%) 并且 K, P 和 Sr 作为次要的部件被识别。当锻烧的蛋壳在包含重金属的合成废水的处理被使用时, Cd 以及在 Cr 的 99% 移动上面的完全的移动在 10 min 以后被观察。尽管自然蛋壳有 Cd 和 Cr 的一些移动能力,完全的移动没由于相当更慢的移动率甚至在 60 min 以后被完成。与 Cd 和 Cr 相对照,然而, Pb 的有效移动与自然蛋壳而非锻烧的蛋壳被观察。从在真实 electroplating 废水的处理的锻烧的蛋壳的申请,锻烧的蛋壳显示出重金属离子的一个有希望的移动能力以及在强壮的酸的废水的处理有一个好中立化能力。 | PARK Heung Jai JEONG Seong Wook YANG Jae Kyu KIM Boo Gil LEE Seung Mok | 2007 | Journal of Environmental Sciences2007，19，12： | 6 |
