RESUMO
Hyperlipidemia is a dyslipidemia caused by dyslipidemia of lipid metabolism， which can be divided into primary and secondary types. The current clinical diagnostic criteria are mainly changes in lipid levels， which are the inducers of high-risk cardiovascular diseases such as atherosclerosis， pancreatitis and coronary heart disease. As a key target in lipid metabolism， peroxisome proliferator-activated receptor α （PPARα） is involved in a variety of metabolic activities， including fatty acid degradation， synthesis， transport， storage， lipoprotein metabolism， etc. Activation of PPARα can maintain the balance of lipid metabolism through a variety of ways， which is an important way to treat hyperlipidemia. At present， chemical drugs such as statins and bettes are mainly used in the clinical treatment of hyperlipidemia. Although they can slow down the disease to a certain extent， there are many adverse reactions and drug resistance. By reviewing the literature in recent years， the author found that the activation of PPARα pathway by traditional Chinese medicine in the treatment of hyperlipidemia has significant effect and small adverse reactions. The lipid-lowering active ingredients include flavonoids， alkaloids， phenols， terpenoids and other compounds. These active components mainly affect the expression of downstream effectors through the activation of PPARα pathway， thereby inhibiting the synthesis of total cholesterol and promoting fatty acid oxidation， and play a role in the treatment of hyperlipidemia. In this paper， we systematically reviewed the structure types and mechanism of active components of traditional Chinese medicine that activate PPARα pathway， so as to provide guidance for the rational development and clinical application of lipid-lowering traditional Chinese medicine new drugs.
RESUMO
Objective: Management of low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) is important for patients with type 2 diabetes merger hyperlipidemia. Pemafibrate (PF) has different characteristics from conventional fibrates. In this study, we retrospectively compared the efficacy and safety of PF and bezafibrate (BF) in patients with type 2 diabetes merger hypertriglyceridemia.Methods: Patients who were administered PF (0.2 mg/day) or BF (400 mg/day) for 24 weeks or longer were included. Twenty patients in each group were extracted using propensity score matching (PS). PS was calculated using the patient background (before the start of administration) of PF or BF. We investigated lipid-related parameters (TG, high density lipoprotein cholesterol [HDL-C], and LDL-C) and other laboratory test parameters pre administration and 24 weeks post administration.Results: TG decreased significantly in both groups (p<0.05). However, there were no significant differences between the two groups in the TG treatment target (<150 mg/dL) achievement rate (p =1.00), TG change rate (p=0.84), and TG change amount (p=0.77). In addition, there were no significant changes in HDL-C and LDL-C in both groups. In the PF group, alanine transaminase (ALT) (p< 0.05), alkaline phosphatase (p<0.05) decreased. In the BF group, ALT (p<0.05) and γ-GTP (p<0.05) decreased. Both groups showed improvement in liver function after 24 weeks. eGFR (p<0.05) significantly decreased only BF group. There were no significant changes in renal function, creatine kinase (CK), or hemoglobin A1c (HbA1c) in either group.Conclusion: Our study suggests that there is no difference in the TG lowering effect and safety of PF and BF in type 2 diabetic patients.
