ABSTRACT
Liver cirrhosis is an end-stage fibrotic disease of chronic liver injury induced by various factors. Many studies have shown that gut microbiota (GM) are involved in the development and progression of liver cirrhosis and related complications, such as portal hypertension, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatocellular carcinoma. In addition, impaired intestinal barrier, compromised liver immunity, and bacterial translocation play a critical role in the progression of liver cirrhosis. This article summarizes the role of GM in liver cirrhosis and related complications and research advances and problems in GM as a therapeutic target, in order to provide new thoughts for clinical diagnosis and treatment.
ABSTRACT
Objective Experimental study on effects of Yangxinshi tablets in the prevention and treatment of chronic is-chemic heart failure and acute myocardial ischemia reperfusion injury in order to provide a theoretical basis for its clinical appli-cation .Method Rat model of chronic ischemic heart failure and acute ischemia reperfusion mouse model of myocardial infarc-tion were constructed through coronary artery ligation .Those animals were randomized to sham operation group ,model group , positive drug group ,high Yangxinshi tablet dose group ,middle Yangxinshi tablet dose group ,low Yangxinshi tablet dose group .Rat electrocardiogram ,ultrasound ,ACE ,ACD ,TNF-a ,mouse myocardial infarction area ,CK ,LDH ,SOD and relat-ed factors were recorded during pre-dosing and post-dosing after modeling .Morphological changes were observed with cardiac pathological section .Results The biochemical indicators in model group were significantly different from sham operation group with statistical significance (P<0 .001) .Compared to the model group ,positive drug group and high Yangxinshi tablet dose group exhibited biochemical differences with statistical significance (P<0 .001 ,P<0 .01 ,P<0 .05) ,significant myocardial in-farction area reduction (P<0 .01 ,P<0 .05) ,improvement in myocardial cells and reduction in the cell infiltration .Conclusion Yangxinshi tablets have preventive and therapeutic effects on chronic ischemic heart failure and acute ischemia reperfusion in-jury .
