Abstract Introduction Steroid-induced osteonecrosis of the femoral head (ONFH) is a disease of the bone. Metabolism and genetic factors are generally considered to play an important role. The purpose of this study was to investigate the relationship between single-nucleotide polymorphisms (SNPs) in MIR17HG and MIR155HG and the risk of steroid-induced ONFH in the population of northern China. Methods A total of 199 steroid-induced ONFH patients and 506 healthy controls were recruited for the study. Four SNPs of MIR17HG and seven SNPs of MIR155HG were genotyped by Sequenom MassARRAY. ORs and 95% CIs were used to evaluate the relationship between these SNPs and steroid-induced ONFH. Results In the codominant model, patients with the MIR17HG SNPs (rs7318578) AA genotype had an increased risk of steroid-induced ONFH (OR = 1.79, p = 0.039); in the recessive model, patients with the MIR17HG SNP (rs7318578) AA genotype had an increased risk of steroid-induced ONFH (OR = 1.78, p = 0.032). Stratified analysis showed that a MIR17HG SNP (rs7318578) and the MIR155HG SNPs (rs77218221, rs11911469, rs34904192 and rs4143370) were closely related to different unornamented phenotypes of steroid-induced ONFH. Analysis of the clinical indicators revealed significant differences in high-density lipoprotein (HDL-C) levels between the ONFH group and the control group (p = 0.005). In the MIR17HG SNP (rs75267932), patients with different genotypes had different levels of triglyceride (TG). The MIR155HG SNPs (rs77699734, rs1893650, and rs34904192) showed differences in triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) levels in patients with different genotypes. Conclusion Our results confirm that MIR17HG and MIR155HG gene mutations are associated with steroid-induced ONFH susceptibility in the population of northern China, providing new evidence for the early detection and prevention of ONFH.

Objectives. High levels of non high density lipoprotein cholesterol (non-HDL-C) are known to contribute to an increased risk of ischemic stroke. This systematic review was conducted to identify the relationship between high non-HDL-C levels and the risk of ischemic stroke. Material and methods. This systematic review using PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement guideline, with a pre-determined search strategy. The search was conducted in Pubmed Central (PMC) and Pubmed from 2009 until 2020 with inclusion criteria, patients with a diagnosis of ischemic stroke, age >18 years, with non-HDL-C levels. The title and abstract of these articles were reviewed for relevance, based on inclusion criteria. This systematic review using STROBE to evaluate the quality in individual study which consists of 22 domains. Results. In the final stage, this systematic review identifies six cohort study consisting 166.720 participants. Overall, the quality in individual studies based on STROBE is good. We reported that there are two studies report that high non-HDL-C levels can significantly increase the risk of ischemic stroke. Meanwhile, there are four studies that report there was no significant relationship between high non-HDL-C levels and the risk of ischemic stroke. Conclusions. Overall, this systematic review provides the result about relationship between high levels of nonHDL-C and the risk of ischemic stroke, there are two studies with a larger population support that high levels of non-HDL-C can increase the risk of ischemic stroke. However, further studies is needed with a large population that specifically identify the relationship between non-HDL-C levels and risk of ischemic stroke and makes a better adjustments for confounding variables.

Abstract Introduction Coronary atherosclerosis is an important pathophysiological mechanism in the development of coronary artery disease (CAD). While it has been proven via multiple studies that elevated levels of low-density lipoprotein (LDL) contribute to the development of atherosclerosis, high-density lipoprotein (HDL) is widely thought to have atheroprotective effects. Multiple epidemiologic studies have given the idea that high HDL levels protect against CAD, however, other trials also shown that its benefit can be paradoxical. Objective To evaluate the relationship between HDL levels and the extent of CAD (one vessel vs multivessel disease) in coronary artery patients. Materials and methods Study analyses of 1676 patients selected from GENEMACOR study population, with at least one >75% coronary stenosis by angiography (median age 53.3±7.9 years, 78.6% male, median HDL 43.0±11.1 mg/dL). Population was divided according to the HDL level quartiles (1st quartile HDL <35.3 mg/dL; 2nd quartile HDL 35.3–42 mg/dL; 3rd quartile HDL 42–49 mg/dL; 4th quartile HDL >49 mg/dL). Population of the 1st and 4th quartiles (825 patients, median age of 53.3±7.9 years and 78.7% male) were adjudicated and prospectively followed-up by 5.0±4.8 years. χ2 and T student tests were used to analyze the demographic, laboratorial, angiographic and anthropometric characteristics of the population according to HDL level. Results 420 (50.9%) patients were included in the 1st quartile group (median age 53.2±7.9 years, 85.7% men) and 405 (49.1%) patients were included in the 4th quartile group (median age 53.4±8.0 years, 71.4% men). In our population, lower levels of HDL were associated with increased risk of multivessel coronary disease (OR 1.63, 95% CI 1.23–2.14, p 0.001). Conclusion Despite uncertainties about HDL benefit, in our population a higer level of HDL was associated with a shortest extent of coronary artery disease. We conclude that higher levels of HDL can be considered protective in coronary patients, and strategies to increase HDL levels may indeed translate in improved outcomes in CAD disease.

OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

Objective: Monocyte to high-density lipoprotein ratio is considered as a new inflammatory marker and has been used to predict the severity of coronary heart disease and the incidence of adverse cardiovascular events (ACEs). However, there is a lack of data relative to large artery atherosclerosis (LAA) ischemic stroke. We investigated whether the monocyte to high-density lipoprotein (HDL) ratio (MHR) is related to the 3-month functional prognosis of LAA ischemic stroke.Materials and Methods: A retrospective analysis was conducted on 316 LAA ischemic stroke patients. The 3-month functional outcome was divided into good and poor according to the modified Rankin Scale (mRS) score. Multivariate logistic regression analysis was performed to evaluate the correlation between MHR and prognosis of ischemic stroke.Results: The MHR level of poor functional outcome group was higher than that of the good functional outcome group [0.44 (0.3, 0.55) vs. 0.38 (0.27, 0.5), P = 0.025]. Logistic stepwise multiple regression revealed that MHR [odds ratio (OR) 9.464, 95%CI 2.257–39.678, P = 0.002] was an independent risk factor for the 3-month poor outcome of LAA ischemic stroke. Compared to the lower MHR tertile, the upper MHR tertile had a 3.03-fold increase (95% CI 1.475–6.225, P = 0.003) in the odds of poor functional outcome after adjustment for potential confounders. Moreover, a multivariable-adjusted restricted cubic spline (RCS) showed a positive close to a linear pattern of this association.Conclusion: Elevated MHR was independently associated with an increased risk of poor 3-month functional outcome of patients with LAA ischemic stroke.

In this study, we evaluated the possible mechanisms through which l-carnitine ameliorates the adverse effects from obesity in rats, induced with a high-fat diet (HFD). For this, 56 albino Wister rats were randomly assigned to 7 groups. The control group was fed a basal diet and injected with saline. The second group was fed the basal diet and injected with l-carnitine (200 mg/kg body mass, by intraperitoneal injection; i.p.). The third group were fed the HFD. The fourth group was fed the HFD and injected with l-carnitine (200 mg/kg body mass, i.p.) for 8 weeks. The fifth group was fed the HFD for 10 weeks. The sixth group were fed the HFD for 10 weeks and were also injected with l-carnitine (200 mg/kg body mass, i.p.) during the final 2 weeks. The seventh group was fed the HFD diet for 8 weeks then the basal diet for 2 weeks. The HFD induced significantly increased levels of hyperglycemia, lipid peroxidation, pathological changes, TNF-α and TGF-β1 protein expression in hepatic tissue, food intake, body weight gain, serum levels of total and non-high-density lipoprotein cholesterol, ketone bodies, triacylglycerol, urea, creatinine, AST, and ALT. However, the HFD diet significantly decreased serum levels of high-density lipoprotein (HDL) and hepatic levels of reduced glutathione. l-Carnitine ameliorated the effects of the HFD on the above-mentioned parameters. This study indicated that l-carnitine had protective and curative effects against HFD-induced hepatosteatosis by reducing hepatic oxidative stress and protein expression of TNF-α and TGF-β1.

Objective: In our study, it was aimed to evaluate the relationship between neutrophil/lymphocyte, monocyte/high-density lipoprotein and magnesium/phosphate ratios with endothelial functions in patients with peripheral artery disease. Methods: Sixty patients followed up with peripheral arterial disease were included in this study. Endothelial functions of the patients were evaluated by flow-mediated vasodilation test. Pearson correlation analysis was used to evaluate the relationship between magnesium/phosphate, neutrophil/lymphocyte, monocyte/high-density lipoprotein ratios with percent change in flow-mediated vasodilation. Results: 48.3% of the participants are male and 51.7% are female. The mean age of the patients were 66.85±11.08 years. The mean radial artery basal diameter was 0.24±0.02 cm in the flow-mediated vasodilatation test and after the test the mean radial artery diameter was 0.27±0.02 cm(p<0.001). In the flow-mediated dilatation test predicting endothelial functions, the percentage change in arterial diameter was positively correlated with the Magnesium/phosphate ratio (r=-0.326, p=0.011), and negatively correlated with the Neutrophil/lymphocyte ratio and monocyte/high-density lipoprotein ratio (respectively r= -0.411, p=0.001; r=-0.530, p=0.001). Conclusion: Magnesium/phosphate ratio, neutrophil/lymphocyte ratio and monocyte/high-density lipoprotein ratio can be used to predict endothelial dysfunction in patients with peripheral artery disease.
