Résumé
Liver cirrhosis is a progressive chronic liver disease due to one or more causes, with diffuse fibrosis in liver tissue, pseudolobules, and regenerative nodules as major histological features. Once liver cirrhosis enters the decompensated stage, the liver and several other organs are injured, which can hardly be recovered or reversed. This article introduces the process of Toll-like receptors in recognizing the changes in intestinal flora and the influence of this process on the development and progression of liver cirrhosis, as well as the protective effect of bile acid against liver cirrhosis by regulating intestinal flora. This article also reviews the advances in delaying liver cirrhosis after the treatment of intestinal dysbacteriosis and points out that the treatment of intestinal dysbacteriosis may become the major direction of liver cirrhosis treatment in future.
Résumé
At present,studies have confirmed the closely relationship between liver diseases and intestinal flora,and regulation of intestinal flora has a certain effect on the progression and therapeutic outcome of liver diseases.With reference to the influencing mechanism of intestinal dysbacteriosis on liver diseases such as alcoholic liver disease,non-alcoholic liver disease,and acute liver injury,this article reviews the research advances in China and foreign countries and summarizes the complications of decompensated liver diseases,such as hepatic encephalopathy and spontaneous bacterial peritonitis,in order to provide new strategies for the treatment of liver diseases in future.
Résumé
Objective To study the correlation between the genetic polymorphism of tumor necrosis factor-α(TNF-α)-308 with benazepril treatment response in the patients with hypertensive renal damage in Ningxia area.Methods Two hundred and eighty-four patients initially diagnosed as hypertension were enrolled and the hypertensive renal damage defined by the measurement of urinary albumin excretion rate(UAER).At the same time 160 individuals undergoing healthy physical examination were selected as the normal blood pressure control group.The plasma samples were obtained from all the subjects,and plasma level of TNF-α and TNF-α-308 gene polymorphism were detected.Then the patients with hypertensive renal damage were interfered with benazepril as one of the antihypertensive drugs,and the treatment response of different TNF-α-308 genotypes to benazepril was observed,and the comparative analysis was performed.Results Among the TNF-α-308 genotypes in the patients with simple hypertension,genotype GA was the most common,followed by GG and AA successively,with the G/A allele frequency of 53 ％/47 ％ (P＜0.05).In the patients with hypertensive renal damage,genotype GG was the most common,followed by GA and AA successively,with the G/A allele frequency of 70％/30％,the genotypes and allele frequency had no statistical difference(P＜0.05).Before and after benazepril treatment,the change range of UAER in the patients with genotype AA was maximal,followed by the genotype GA and GG,the difference among 3 groups was statistically significant(P＜0.05).Conclusion The TNF-α-308 gene is correlated with hypertensive renal damage and its response to benazepril treatment.
Résumé
Objective To study the relationship between the genetic polymorphism of interleukine-6 (IL-6)-174 and the response to benazepril treatment in patients with hypertensive renal damage. Methods Two hundred and eighty-four patients with hypertension were enrolled in this study. The hypertensive renal damage was defined by the measurement of urinary albumin excretion rate (UAER). One hundred and sixty healthy subjects were enrolled simultaneously as control group. Blood samples were obtained from all the subjects, and plasma levels of IL-6 and the genotype of gene IL-6-174 were detected. The patients with hypertensive renal damage were treated with benazepril for 16 weeks. The responses were evaluated by the changes of UAER level to benazepril in different genotypes. Results Genotype CC was the most common of the gene IL-6-174 in patients with hypertension, followed by GG and GC successively, with the G/C allele frequency of 47%and 53%(P<0.05), while in patients with hypertensive renal damage, GG was the most common genotype of the gene IL-6-174, followed by GC and CC successively, with the G/C allele frequency of 68%and 32%(P<0.05). After benazepril treatment, the UAER was decreased most in patients with genotype CC, followed by GC and GG successively ( P<0.05). Conclusion The G allele frequency of the gene IL-6-174 is related with hypertensive renal damage in patients in Ningxia, with GG as the most common genotype. The patients with CC genotype have the best response to benazepril treatment, with most decreased UAER.
