1Extragastric manifestations of Helicobacter pylori infection: Possible role of bacterium in liver and pancreas diseases显示文摘Helicobacter pylori(H. pylori) is an ancient microorganism that has co-evolved with humans for over 60000 years. This bacterium typically colonizes the human stomach and it is currently recognized as the most common infectious pathogen of the gastroduodenal tract. Although its chronic infection is associated with gastritis, peptic ulcer, dysplasia, neoplasia, MALT lymphoma and gastric adenocarcinoma, it has been suggested the possible association of H. pylori infection with several extragastric effects including hepatobiliary and pancreatic diseases. Since a microorganism resembling H. pylori was detected in samples from patients with hepatobiliary disorders, several reports have been discussed the possible role of bacteria in hepatic diseases as hepatocellular carcinoma, cirrhosis and hepatic encephalopathy, nonalcoholic fatty liver disease and fibrosis. Additionally, studies have reported the possible association between H. pylori infection and pancreatic diseases, especially because it has been suggested that this infection could change the pancreatic physiology. Some of them have related a possible association between the microorganism and pancreatic cancer. H. pylori infection has also been suggested to play a role in the acute and chronic pancreatitis pathogenesis, autoimmune pancreatitis, diabetes mellitus and metabolic syndrome. Considering that association of H. pylori to liver and pancreas diseases needs further clarification, our work offers a review about the results of some investigations related to the potential pathogenicity of H. pylori in these extragastric diseases.Elizabeth MA Rabelo-Goncalves Bruna M Roesler Jose MR Zeitune 2015World Journal of Hepatology2015,7,30:16
2慢性肾脏病中的炎症和动脉硬化:慢性肾功能不全队列研究中的发现显示文摘慢性肾脏病(chronic kidney disease,CKD)和动脉硬化程度与心血管病发病率和死亡率增加相关。目前认为炎症在动脉硬化发展中发挥作用,而CKD被认为是一种促炎症反应的状态。CKD患者的动脉僵硬度增加,横断面数据提示CKD中增多的炎症标志物与较高动脉僵硬度值相关。Peyster E Chen J Feldman HI Go AS Gupta J Mitra N Pan Q Porter A Rahman M Raj D Reilly M Wing MR Yang W Townsend RR 陈云 叶鹏 2017中华高血压杂志2017,25,11:12

4Biochemical changes in phenols,flavonoids,tannins,vitamin E,β-carotene and antioxidant activity during soaking of three white sorghum varieties显示文摘Objective:To investigate the changes in total phenols,flavonoids,tannins,vitamin E, β-carotene and antioxidant activity during soaking of three white sorghum varieties.Methods: The changes in total phenols,total ilavonoids,tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity during soaking of sorghum grains were determined.Results:Total phenols,total flavonoids,tannins,vitamin E,P-carotene and antioxidant activity in raw sorghum were ranged from 109.21 to 116.70,45.91 to 54.69,1.39 to 21.79 mg/100 g,1.74 to 5.25,0.54 to 1.19 mg/kg and 21.72%to 27.69%and 25.29%to 31.97%,respectively. The above measured compounds were significantly decreased after soaking.p-Hydroxybenzoic acid,vanillic acid,syringic acid and cinnamic acid represent the major phenolic acids in Dorado variety.While ferulic acid,p-coumaric acid,gallic acid and caffeic acid represent the major phenolic acids in Shandaweel-6.On the other hand,protocatechuic acid represents the major phenolic acids in Giza-15.Regarding flavonoids components,Dorado was the highest variety in kampferol and naringenin while Shandaweel-6 was the highest variety in luteolin, apigenin,hypersoid,quercelin and christen.Finally,Giza-15 was the highest variety in catechin. Phenolic acids,flavonoid compounds and antioxidant activities were decreased after soaking. Conclusions:Sorghum varieties have moderate quantities from total phenols,total flavonoids, tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity which decreased after soaking.Abd El-Moneim MR Afify Hossam S El-Beltagi Samiha M Abd El-Salam Azza A Omran 2012Asian Pacific Journal of Tropical Biomedicine2012,2,3:7

6从远志中分离鉴定出1种多巴胺受体活性化合物显示文摘目的从中药远志中提取脑内多巴胺(DA)受体活性化合物。方法用体外的放射配体-受体结合和高压液相法提取、分离、纯化DA受体活性化合物,用核磁共振和质谱仪确定活性化合物的结构。结果提取、分离到1种四氢非洲防己胺的活性化合物。其在体外可抑制3H-SCH23390(DA1受体亚型)和3H-螺呱隆(DA2受体亚型)与大鼠纹状体细胞膜的结合,其IC50值分别为(0.75±0.08)μmol/L和(0.92±0.10)μmol/L。这种活性化合物还能抑制3H-呱唑嗪和大鼠大脑膜α1-肾上腺素受体的结合(IC50值为46μmol/L),但是不能改变3H-QNB及3H-muscimol对膜的结合。Scatchardplot分析显示此化合物对3H-SCH23390和3H-螺呱隆与纹状体细胞膜的结合的抑制作用是通过竞争性与非竞争性混合机制而实现的。结论远志中提取到的四氢非洲防己胺是脑内多巴胺受体的活性化合物,它的抑制作用是通过竞争性与非竞争性混合机制而实现的。沈行良 Witt MR Dekermendjian K Nielsen M 2004海南医学院学报2004,10,3:7

8Cytokine profile in Egyptian hepatitis C virus genotype-4 in relation to liver disease progression显示文摘AIM: To observe the imbalance between T helper cell Th1 and Th2 cytokines in several chronic hepatitis disease at different stages of disease progression.METHODS: We measured the cytokine levels of Th1 (IL-2 and IL-2R), Th2 (IL-10) and the pro-inflammatory cytokines (IL-6 and IL-6R and TNF and TNF-RⅠ and Ⅱ)by the ELISA technique in the sera of 33 hepatocellular carcinoma (HCC) patients and 20 chronic liver disease (CLD) patients. In addition, 20 asymptomatic hepatitis C virus carriers and 20 healthy subjects negative for hepatitis C virus(HCV) markers served as controls.RESULTS: Anti-HCV antibodies were found to be positive in 94% of HCC cases and 75% of CLD cases.On the other hand, HCV viremia was detected using RTPCR in 67% of HCC cases and 65% of CLD cases. HBsAg was positive in 9% of HCC cases and 30% of CLD cases.Also bilharzial-Ab was positive in 55% of HCC cases,65% of CLD cases and in 70% of asymptomatic carriers (ASC). HCC patients had significantly higher values of IL-2R, TNF-RⅡ (P<0.001), and TNF-RⅠ (P>0.05), but lower TNFα (P<0.001) and IL-6 (P = 0.032) in comparison to ASC. But, in comparison to non-cancer controls, HCC patients had higher values of IL-2R, IL-6R, TNF-RⅠ and TNF-RⅡ, but lower TNF-α (P<0.001). CLD patients had higher IL-2R, TNF-RⅠ, and TNF-RⅡ (P<0.001) than ASC. But, in comparison to non-cancer controls, CLD patients had higher values of IL-2R, TNF-RⅠ and TNF-RⅡ, but lower TNF-α (P<0.001). IL-10 was higher (though not significantly) in HCC and CLD patients than in symptomatic carriers and non-cancer controls.CONCLUSION: Liver disease progression from CLD to HCC due to HCV genotype-4 infection is associated with an imbalance between Th1 and Th2 cytokines. IL-2R,TNF-RⅠ, and TNF-RⅡ could be used as potential markers.Abdel-Rahman N Zekri Mohammed S El-Din Ashour Ahmed Hassan Hanaa M Alam El-Din Amal MR El-Shehaby Maha A Abu-Shady 2005World Journal of Gastroenterology2005,11,42:4

14Genetic diversity of HCV among various high risk populations(IDAs,thalassemia,hemophilia,HD patients) in Iran显示文摘Objective:To determine the patterns of distribution of HCV genotypes among high risk population in north of Iran.Methods:A cross-sectional study was conducted on 135 HCV RNA-positive high risk individuals including thalassemia,hemophilia,patients under hemodialysis and intravenous drug addicts.HCV genotypes were determined based on amplification with type-specific primers methods.Results:Among the 187 anti-HCV positive samples,only 135 (72.2%)gave HCV-RNA positvity.Over all,the most identified HCV type was genotype 3a(51.1%) followed by 1a(27.4%),1b(8.2%).Sixteen(11.9%)out of 135 HCV RNA-positive participants have infected with more than one genotype or subtypes as follow:1a/1b in 11(8.2%),2/3a in 3 (2.2%),and 1a/1b/3a in 2(1.5%).Stratification of participants revealed that HCV subtype 3a was more prominent in thalassemia,hemophilia and HD patients but 1a and 1b were frequent in intravenous drug addicts.Conclusions:This study is the first report on HCV genotypes among Iranian subjects with different exposure categories resided in Mazandaran.where genotype 3a was found to be the most frequent genotype in thalassemia,hemophilia,and hemodialysis patients but not in IDAs.Since the addiction age is decreasing in Iran and a lot of addicts are IDAs.it might change the subtype pattern of HCV in general population.Rafiei A Darzyani Azizi M Taheri S Haghshenas MR Hosseinian A Makhlough A 2013Asian Pacific Journal of Tropical Medicine2013,6,7:2
