Background. Acupoint embedding treatment on obesity has been applied in clinical practice for many years and has achieved obvious efficacy. However, animal experimental studies on acupoint embedding are relatively few, and its mechanism remains unclear. Methods. We established a simple obese rat model using a high-fat diet for 8 weeks. Acupoint embedding therapy was performed once a week for 4 weeks. After the treatment, serum leptin, triglyceride (TG), cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels were detected by radioimmunoassay, HE staining was used for fat morphology analysis, and immunohistochemical method was used to detect the expression of leptin receptor in hypothalamus. Results. Compared with model group, acupoint embedding treatment can reduce body weight and Lee's index, reduce serum leptin, TG, TC, and LDL level, increase HDL level, change the morphology and number of adipocytes, and increase the expression of leptin receptor in hypothalamus. Conclusion. Acupoint embedding therapy can reduce the level of leptin in blood, increase the number of leptin receptors in hypothalamus, enhance the biological effect of leptin, alleviate the leptin resistance in obese body, change the shape of fat, and regulate the level of blood lipid, so as to achieve the goal of weight loss.

AbstractDyslipidemia is one of the main risk factors for coronary heart disease (CHD). The E3 ubiquitin ligase which is encoded by the ring finger protein 145 (RNF145) gene is very important in the mediation of cholesterol synthesis and effectively treats hypercholesterolemia. Thus, the purpose of the present research is to investigate the connection between the polymorphism of the RNF145 gene and cholesterol levels in the populations in Xinjiang, China. A total of 1396 participants (Male: 628, Female: 768) were included in this study for genetic analysis of RNF145 gene, and we used the modified multiple connection detection response (iMLDR) technology to label two SNPs (rs17056583, rs12188266) of RNF145 genotyping. The relationship between the genotypes and the lipid profiles was analyzed with general linear model analysis after adjusting confounding variables. Through the analysis of the two SNPs in RNF145 gene, we discovered that both rs17056583 and rs12188266 were related to total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations (All P < 0.001). In addition, the association of rs17056583 and rs12188266 with lipid profiles concentrations is still statistically significant after multivariate adjustment of sex, age, smoking, obesity, drinking, diabetes, hypertension and lipid profiles. Meanwhile, we also found that rs17056583 was associated with high triglycerides concentrations before and after adjustment (All P < 0.001). Our study shows that both rs17056583 and rs12188266 SNPs of RNP145 gene are related to TC and LDL-C concentrations in Xinjiang population.

Regulation of the expression of platelet-activating factor (PAF) receptor by atherogenic lipoproteins might contribute to atherogenesis. We show that progressive oxidation of low-density lipoprotein (LDL) gradually inhibits PAF receptor expression on the macrophage cell surface. We tested the effect of oxidized LDL (oxLDL) on PAF receptor expression in human monocytes that do not contain peroxisome-proliferator-activated receptor γ (PPARγ), a nuclear receptor activated by oxLDL. OxLDL decreased by 50% (P ⩽0.001) and by 29% (P⩽0.05) the binding of PAF and the expression of PAF receptor mRNA respectively. Next we demonstrated that progressive oxidation of LDLs significantly activated PPARα-dependent transcription in transfected mouse aortic endothelial cells. Finally we demonstrated, in mature macrophages, that fenofibrate (20µM), a specific PPARα agonist, but not the specific PPARγ agonist BRL49653 (20nM), significantly decreased both PAF binding and PAF receptor mRNA expression, by 65% and 40% (P⩽0.001) respectively. Additionally, another PPARα agonist, Wy14,643, decreased PAF receptor promoter activity by 70% (P⩽0.05) in transfected THP-1 cells, suggesting the involvement of the proximal promoter region (-980 to -500) containing a series of four nuclear factor (NF)-κB motifs. Thus PPARα might be involved in the down-regulation of PAF receptor gene expression by oxLDLs in human monocytes/macrophages. The oxidation of one or more lipid components of LDLs might result in the formation of natural activators of PPARα. It is hypothesized that such activators might modulate inflammation and apoptosis upon atherogenesis by decreasing the expression of PAF receptor.

AbstractObjective:  Postpartum obesity leads to long-term maternal obesity and promotes drastic health complications. Low glycemic index diet is suggested to have a beneficial impact on blood lipid levels. Therefore, we conducted a study to explore the effect of low glycemic diet on blood lipid profile in obese postpartum women.Methods:  In a randomised controlled trial, 38 obese postpartum women in intervention and 36 obese post-partum women in control group were analysed. Subjects in the intervention group were assigned low glycemic index diet and to follow this protocol for 12 weeks and the control group was advised to continue their routine diet.Results:  Low glycemic diet had a positive impact on low density lipoprotein (LDL), triglyceride and highdensity lipoprotein (HDL) concentration (p < 0.05). A strong positive correlation was observed between the glycemic index and LDL (mg/dl), (r = 0.57; p = 0.02) and between glycemic index and triglyceride (mg/dl), (r = 0.51; p = 0.01) in control and intervention group. A negative correlation was identified between glycemic index and HDL (mg/dl), (r = -0.45; p = 0.01).Conclusion:  Study concluded that low glycemic index diet reduced low density lipoprotein and triglyceride level and increased HDL level in blood; further more a significant association was found between glycemic index and blood lipids profile.

Aim.To study the associations between blood lipid profile and blood glucose levels in men with coronary heart disease (CHD), stable effort angina (SEA), metabolic syndrome (MS), and Type 2 diabetes mellitus (DM-2).Material and methods.The study included 82 men (mean age 50,5±0,9 years) with CHD, Functional Class I–III SEA, MS, and DM-2. The following lipid profile parameters were assessed: total cholesterol (TCH), triglycerides (TG), low-density lipoprotein cholesterol (LDL–CH), very low-density lipoprotein cholesterol (VLDL–CH), high-density lipoprotein cholesterol (HDL–CH), atherogenic index (AI), and triglyceride index (TGI), together with fasting blood glucose.Results.There were positive (direct) associations between higher levels (>90th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, HDL–CH, AI, TGI) and blood glucose, as well as between lower levels (≤10th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, AI, TGI) and blood glucose. At the same time, there were negative (inverse) associations between lower lipid levels (≤10th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and higher glucose levels (>90th percentile), as well as between higher lipid levels (>90th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and lower glucose levels (≤10th percentile).Conclusion.Dyslipidemia and hyperglycemia demonstrate synergetic proatherogenic effects in patients with CHD, SEA, MS, and DM-2, as suggested by significant heterogeneous (direct and inverse) associations between lipid profile parameters and fasting blood glucose. The results obtained provide an opportunity for the assessment of risk levels, prognosis, and need for pharmacological prevention and treatment in patients with combined cardiovascular pathology.

Abstract Background According to the "lipid nephrotoxicity hypothesis", there is now significant research being conducted in this area. By studying the role of hyperlipidemia in chronic kidney disease in the general Zhejiang population, we aimed to explore the correlation between changes in blood lipid levels and chronic kidney disease.Methods We collected and analyzed clinical data from ordinary residents who participated in the annual comprehensive physical examination with no overt kidney disease in Zhejiang Provincial People's Hospital, China from January 2011 to December 2016. According to triglyceride, total cholesterol and low-density lipoprotein levels, participants were respectively divided into 4 groups. Statistical methods were used to evaluate the correlation between different blood lipid profiles and chronic kidney disease.Results 5,183 participants were included in our study. During the six-year follow-up period, 227 participants (4.4%) developed chronic kidney disease. The odds ratio for incident chronic kidney disease was 3.14 (95%CI: 1.53–6.43) in Q3, 3.84 (95%CI: 1.90–7.76) in Q4 according to the total cholesterol group and 1.17 (95%CI: 1.04–1.32) in Q3, 1.40 (95%CI: 1.11–2.48) in Q4 according to the low-density lipoprotein group, respectively, after multivariable-adjusted analyses. According to the triglyceride grouping, the odds ratio for incident chronic kidney disease was 2.88 (95%CI: 1.29-6.43) in Q2, 2.92 (95%CI: 1.44–6.57) in Q3 and 3.08 (95%CI: 1.11–6.69) in Q4, after multivariable-adjusted analyses.Conclusion Increased triglycerides and high levels of total cholesterol and low-density lipoprotein were independently associated with an increased likelihood of eGFR decline and development of incident chronic kidney disease in the general Zhejiang population.

Abstract BANKGROUND: Mortality from coronary artery disease continues to rise, and secondary prevention and treatment are particularly important. OBJECTIVE: The objective of this study is to evaluate low-density lipoprotein cholesterol (LDL-C) levels in patients after percutaneous coronary intervention (PCI), to describe how treatment outcomes for individual patients changed over time and to examine the potential impact of lipid control rates through population LDL-C levels changes.METHODS: This retrospective study was conducted in patients who underwent PCI between July 2017 and June 2019. The main results included LDL-C levels after PCI. To assess the outcome of prevention, three separate measures of LDL-C were considered: baseline, first follow-up, and final follow-up, and LDL-C control rates were analyzed according to different guidelines. we examine the impact of 0.1mmol/l decreases or increases in population LDL-C levels on LDL-C control.RESULTS: Data were analyzed for 423 patients (mean age, 62 ±10 years), and the baseline LDL-C level was 3.11 ± 0.99 mmol/l. 51.5% of the patients achieved the Chinese Lipids Guidelines treatment goal, 22% and 11.6% of the patients achieved the 2016 ESC Lipids Guidelines and 2019 ESC Lipids Guidelines treatment goal at the final follow-up period respectively. LDL-C levels fluctuated during the follow-up period, and the long-term maintenance results could not be guaranteed after PCI. Population LDL-C levels changes in lifestyle could have a very large impact on LDL-C control in China.CONCLUSION: LDL-C control with statins is not ideal in patients after PCI, which is far from the requirements of the latest guidelines. Although clinicians understand the lipid-lowering effect of statins, they should not give up active lifestyle changes, and should strengthen the comprehensive management of blood lipid control.

The aim: Research of blood lipid spectrum, level of anti-inflammatory cytokines and C-reactive protein of coronary heart disease patients. Materials and methods: There was examined 61 patients with unstable angina, who had been on hospital care in the cardiology department of the Lviv National Emergency Hospital. Their average age was 68.3 ± 1.9 years. The control group included 20 generally healthy persons. There was estimated blood lipid spectrum, C-reactive protein, fibrinogen and proinflammatory cytokine of patients. Results: There was determined considerable increase total cholesterol, low density lipoprotein cholesterol, very low density lipoprotein cholesterol, triglycerides and coefficient of atherogenicity. High level of C-reactive protein and pro-inflammatory cytokines were detected in patients with unstable angina. Conclusions: In patients with unstable angina was revealed a significant increase of proinflammatory cytokines levels in the blood serum: interleukin-1β, interleukin-6, interleukin-17, TNF-α and C-reactive protein, fibrinogen, which indicates activation of the inflammatory process. In patients with unstable angina was detected a significant disorder of blood lipid spectrum. For its correction should be recommended diet and hypolipidemic agents.
