The role of polysaccharide peptide of Ganoderma lucidum as a potent antioxidant against atherosclerosis in high risk and stable angina patients

ObjectivesAntioxidants can reduce oxidative radicals that affect the early phase of atherogenesis, that is endothelial dysfunction. Polysaccharide Peptide (PsP) derived from Ganoderma lucidum has an active substance in the form of β-glucan. Previous studies have proven the PsP of Ganoderma lucidum as an effective antioxidant in atherosclerotic rats and shows no toxicity in animal model. This study aims to prove the effect of PsP as potent antioxidant in high risk and stable angina patients.MethodThis is a clinical trial conducted to 37 high risk and 34 stable angina patients, which were determined based on ESC Stable CAD Guidelines and Framingham risk score, with pre and post test design without control group. The parameters are superoxide dimustase (SOD) and malondialdehyde (MDA) concentration, circulating endothelial cell (CEC) and endothelial progenitor cell (EPC) counts. The patients were given PsP 750 mg/day in 3 divided dose for 90 days. Paired t-test was performed for normally distributed data, and Wilcoxon test for not normally distributed data, and significant level of p ≤ 0,05.ResultsSOD level in high risk patients slightly increased but not statistically significant with p = 0,22. Level of SOD in stable angina group significantly increased with p = 0,001. MDA concentration significantly reduced in high risk and stable angina patients with p = 0.000. CEC significantly reduced both in high risk and stable angina patients, with p = 0.000 in both groups. EPC count significantly reduced in high risk and stable angina with p = 0.000.ConclusionPsP of Ganoderma lucidum is a potent antioxidant against pathogenesis of atherosclerosis in stable angina and high risk patients

稳定性心绞痛患者血糖水平与循环微小RNA-92a表达关系的研究

目的探讨稳定性心绞痛(SAP)患者循环微小RNA-92a(microRNA-92a,miR-92a)表达与血糖的关系。方法将93例SAP患者分为A组:降糖治疗+空腹血糖(FPG)<7.0 mmol/L 18例,B组:降糖治疗+FPG≥7.0 mmol/L8例,C组:非降糖治疗+FPG<7.0 mmol/L 61例,D组:非降糖治疗+FPG≥7.0 mmol/L 6例。比较4组患者血糖水平与循环miR-92a表达的关系。结果 SAP患者合并2型糖尿病发病率为34.4%,降糖治疗后,仍有30.8%FPG≥7.0 mmol/L。A组与B组miR-92a是否>-0.1或>0.5水平的OR值分别为2.67或0.17,C组与D组OR值分别为0.36、0.48。A组miR-92a>-0.1的患者为88.9%,显著高于C组的41.0%(P<0.01)。B组miR-92a>0.5的患者为75.0%,高于A组的33.3%(P>0.05)。结论单纯测定FPG诊断2型糖尿病漏诊率高。循环miR-92a有助于FPG<7.0 mmol/L的SAP合并2型糖尿病的诊断及疗效评价。     

The role of nicorandil in the treatment of myocardial ischaemia

Nicorandil is an anti-anginal agent that has been used in the United Kingdom for over 6 years and is becoming increasingly popular. It induces coronary and peripheral vasodilatation via a dualistic mode of action, mediated by the opening of potassium-ATP channels (K_ATP) and its nitrate effect by stimulation of adenyl cyclase, with an increase in cGMP levels. Comparison to nitrates and other anti-anginal agents have shown it to be of equal efficacy in relieving ischaemic symptoms. Recent evidence suggests a role for nicorandil as a myocardial preconditioning agent but this may be limited by systemic vasodilatation. There is ongoing research into its role in improving the long-term outcome of patients with ischaemic heart disease (IHD). It has been shown to be of proven efficacy in the treatment of IHD and further research will clarify other uses of this agent.
