Research progress of celastrol on the prevention and treatment of metabolic associated fatty liver disease / 生理学报

Metabolic associated fatty liver disease (MAFLD) is a liver disease with hepatocyte steatosis caused by metabolic disorders, which is closely related to obesity, diabetes, metabolic dysfunction, and other factors. Its pathological process changes from simple steatosis, liver inflammation to non-alcoholic steatohepatitis (NASH), and then leads to liver fibrosis, cirrhosis, and liver cancer. At present, no specific therapeutics are available for treatment of MAFLD targeting its etiology. Celastrol is the main active component of the traditional Chinese medicine Celastrus orbiculatus Thunb. In recent years, it has been found that celastrol shows important medicinal value in regulating lipid metabolism, reducing fat and weight, and protecting liver, and then ameliorates MAFLD. This article reviews the related research progress of celastrol in the prevention and treatment of MAFLD, so as to provide a reference for the comprehensive development and utilization of celastrol.

Research advances on preventive and therapeutic effects of hydrogen on cardiovascular and cerebrovascular diseases and underlying mechanisms / 生理学报

For a long time, hydrogen (H) has been considered as a physiological inert gas. However, recent studies have demonstrated that molecular H exerts significant therapeutic effects on various disease models due to its antioxidative, anti-inflammatory and anti-apoptotic capabilities, which have also been well confirmed in many clinical trials. Cardiovascular and cerebrovascular diseases (CCVDs) are the leading cause of death in the world, constituting a serious threat to human life and public health. In this paper, we reviewed the latest research progress of the biomedical effects of H in CCVDs and its possible molecular mechanisms, in the hope of providing new clues for the treatment of some CCVDs.

Protective effect of antioxidative ?-lipoic acid on kidneys in type 2 diabetic rats / 中华内分泌代谢杂志

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.
