Salvia miltiorrhiza Depresses Plasminogen Activator Inhibitor-1 Production Through Inhibition of Angiotensin II

Managing the combination of nonalcoholic Fatty liver disease and metabolic syndrome with chinese herbal extracts in high-fat-diet fed rats

Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome (MetS). The aim of the study was to evaluate the effects of Chinese herbal extracts from Salvia miltiorrhiza and Gardenia jasminoides (SGE) on the combination of NAFLD and MetS induced by a high-fat diet (HFD) in rats. After 6 weeks of HFD feeding, rats (n = 10 each group) were treated with saline, rosiglitazone (RSG), and SGE for 4 weeks. HFD rats were obese, hyperinsulinemic, hyperlipidemic and increased hepatic enzymes with the histological images of NAFLD. Treatment with SGE significantly reduced serum triglycerides (TG), nonesterified fatty acids and enhanced insulin sensitivity, and ameliorated the elevated serum hepatic enzymes compared with HFD-saline group. SGE treatment also attenuated hepatic TG by 18.5% (P < 0.05). Histological stains showed SGE decreased lipids droplets in hepatocytes (P < 0.05) and normalized macrovesicular steatosis in HFD rats. Significant reduction of TNF-α and IL6 in adipose tissue was detected in SGE treated rats. The anti-inflammatory action may be, at least in part, the mechanism of SGE on MetS associated with NAFLD. This study discovered that SGE is capable of managing metabolic and histological abnormalities of NAFLD and MetS. SGE may be an optimal treatment for the combination of NAFLD and MetS.

Optimized project of traditional Chinese medicine in treating chronic kidney disease stage 3: a multicenter double-blinded randomized controlled trial

ETHNOPHARMACOLOGICAL RELEVANCE

Stage 3 is the key phase of chronic kidney disease. Traditional Chinese medicine (TCM) has been used for the treatment of chronic kidney disease. But a large sample trial is desirable.

MATERIALS AND METHODS

A total of 578 Chinese patients with primary glomerulonephritis in CKD stage 3 were randomly assigned to three groups: patients received TCM (TCM group), benazepril (Ben group), TCM combined with benazepril (TCM+Ben group). Patients were followed up for 24 weeks. The primary endpoint was the time to the composite of 50% increased of serum creatinine, end stage renal disease or death.

RESULTS

eGFR in the TCM and the TCM+Ben group were improved (week 24 vs. baseline, P<0.05) while eGFR in the Ben group was decreased (week 24 vs. baseline, P>0.05). 24h urinary protein excretion (UP) and urinary albumin/creatinine (UAlb/Cr) were decreased in the TCM+Ben (week 24 vs. baseline, P<0.05) and the Ben group (week 24 vs. baseline, P>0.05). UP and UAlb/Cr were increased in the TCM group to week 12, then were stable (week 24 vs. baseline, P<0.05). The hemoglobin in the TCM group was also improved (week 24 vs. baseline, P<0.05). The accumulative survival rate in the TCM+Ben group was higher than that in the TCM group and the Ben group (P=0.044). Side effects in the TCM group were the lowest in these groups (P<0.05). The patients with dry cough in the TCM+Ben group and the Ben group were increased as compared with the TCM group (P<0.05). Hyperkalemia happened less frequently in the TCM group as compared with the other two groups (P=0.052).

CONCLUSIONS

For the patients with CKD stage 3, TCM can improve eGFR and hemoglobin with lower side effects. Benazepril significantly decreased the proteinuria. Chinese medicine integrated with benazepril can ameliorate renal function and decrease proteinuria synergistically.
