ABSTRACT
Background: Hypothyroidism (especially subclinical hypothyroidism) and Metabolic Syndrome (MetS) association have been controversial. Aim and Objectives: This study was aimed to examine the MetS components in patients with Clinical and Subclinical Hypothyroidism (CH & SCH) in northeast Iran. Material and Methods: In this cross-sectional study, 186 hypothyroid patients were evaluated for MetS using NCEP-ATP III criteria. Thyroid function and lipid profile parameters were measured using ELISA and enzymatic photometric methods. Results: MetS was common in 53.2% of hypothyroid patients. The odds of MetS in 50 years and above were about 3.2 times higher than those under 50 (p = 0.001). Simple logistic regression analysis showed decreasing one mg/dl High-Density Lipoprotein Cholesterol (HDL-C) increased nearly 10% odds of MetS (OR = 0.916; 95% CI: 0.882–0.951; p = 0.001). In addition, rising one unit Waist Circumference (WC) increased about 14% odds of MetS (OR = 1.137; 95% CI: 1.092–1.183; p = 0.001).As well as, multiple logistic regression analysis showed low HDL-C (p = 0.0001), high SBP (p = 0.0001), and high WC (p = 0.009) had the most significant effect on developing MetS, respectively. Conclusion: This study determined that CH and SCH are significantly associated with MetS. In addition, MetS significantly increased in reduced HDL-C, increased SBP, and age more than 50.
ABSTRACT
Objective To explore the correlation between blood uric acid/HDL-C ratio(UHR)and peripheral neuropathy(DPN)in T2DM.Methods A total of 127 T2DM patients admitted to the Endocrinology Department of Wujin Traditional Chinese Medicine Hospital in Changzhou City from August 2022 to August 2023 were selected.They were divided into a simple T2DM group(n=62)and a combined DPN group(DPN,n=65)based on whether or not they had DPN.Compare two groups of general information,biochemical indicators,and UHR.Results Compared with the T2DM group,DPN group DM course of disease,HbA1c,FPG,FIns,HOMA-IR,TG,vibration sensation threshold(VPT),hypersensitive C-reactive protein(hs-CRP),blood uric acid(SUA),and UHR(P＜0.05),HDL-C,tibial nerve motor nerve conduction velocity(mNCV),and superficial peroneal nerve sensory nerve conduction velocity (sNCV)decreased(P＜0. 05). Spearman correlation analysis showed that UHR was positively DM duration of disease,HbA1c,FPG,HOMA?IR,TG,VPT,hs?CRP,and SUA(P＜0. 05),negatively correlated with mNCV,sNCV,and HDL?C(P＜0. 05). Logistic regression analysis showed that UHR,DM duration, hs?CRP,and HbA1c were the influencing factors of DPN. Conclusion Elevated UHR is a influencing factor for the occurrence of DPN in T2DM patients and has good predictive value for DPN.
ABSTRACT
The key pathogenesis of coronary heart disease （CHD） is spleen deficiency and phlegm stasis， and dysfunctional high-density lipoprotein （dys-HDL） may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein （HDL）， it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL； and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways， namely， mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells， thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency， and spleen deficiency makes foundation for the production of dys-HDL； dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen， resolving phlegm， and dispelling stasis， is proposed as an important principle in the treatment of CHD by traditional Chinese medicine， which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL， thus revealing the scientific connotation of this method， and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

ABSTRACT
Objective:To characterize the longitudinal and dynamic high-density lipoprotein (HDL) trajectories in critically ill children and explore their correlation with clinical outcomes.Methods:Retrospective cohort study.All critically ill children admitted to the Pediatric Intensive Care Unit (PICU) of West China Hospital, Sichuan University from January 1, 2015 to October 1, 2020 were included in this retrospective study.Group-based trajectory modeling (GBTM) was applied to characterize the HDL trajectories in days 0-6 post-PICU admission and develop HDL trajectory groups.The in-hospital mortality rate was reported as frequency (%) and then compared by the Chi-square test or Fisher′s exact test between HDL trajectory groups.The length of stay (LOS) in the PICU was described by M( Q1, Q3), and its difference between HDL trajectory groups was evaluated by the Kruskal Wallis test.Logistic regression and multiple linear regression were used to determine the correlation between HDL trajectories and clinical outcomes.The primary outcome was in-hospital mortality rate, and the secondary outcome was LOS in the PICU. Results:A total of 4 384 critically ill children were ultimately enrolled in the study, and 6 HDL trajectory groups were developed based on GBTM analyses: group 1 (758 cases), the lowest HDL group; group 2 (1 413 cases), the low HDL group; group 3 (74 cases), the low-to-high HDL group; group 4 (621 cases), the medium HDL group; group 5 (1 371 cases), the high HDL group; and group 6 (147 cases), the highest HDL group.Logistic regression analysis showed that compared with critically ill children in group 1, those belonging to groups 2, 3, 4, 5, and 6 were at lower risks of in-hospital mortality with odds ratio ( OR): 0.475, 95%confidence interval ( CI): 0.352-0.641, P<0.001; OR: 0.093, 95% CI: 0.013-0.679, P=0.019; OR: 0.322, 95% CI: 0.208-0.479, P<0.001; OR: 0.263, 95% CI: 0.185-0.374, P<0.001, and OR: 0.142, 95% CI: 0.044-0.454, P=0.001, respectively.Multiple linear regression analysis revealed that compared with critically ill children in group 1, those belonging to groups 4, 5, and 6 had the trend of shorter LOS in PICU, and the β value and 95% CI were β: -4.332, 95% CI: -5.238- -3.426, P<0.001; β: -3.053, 95% CI: -3.809--2.297, P<0.001; β: -6.281, 95% CI: -7.842--4.721, P<0.001, respectively. Conclusions:The dynamic HDL trajectories during 0-6 days after PICU admission are associated with in-hospital mortality rate of critically ill children.The HDL trajectory at a persistently low level is associated with higher mortality, while the HDL trajectory at a persistently high level or with the trend from a low level rising to a high level shows a lower risk of mortality.It is suggested that the HDL trajectory model may become an indicator to predict the condition and prognosis of critically ill children.
ABSTRACT
BACKGROUND:Oxidative modification of high-density lipoprotein occurs in patients with polycystic ovary syndrome.However,the relationship between oxidized high-density lipoprotein and ovulation dysfunction and its mechanism are unknown. OBJECTIVE:To investigate the effect and potential mechanism of oxidized high-density lipoprotein on ovarian granulosa cell apoptosis. METHODS:Polycystic ovary syndrome rat model was established,then the high-density lipoprotein was harvested from the rat serum of heart blood.The degree of oxidation of the high-density lipoprotein was detected by high-density lipoprotein inflammation index assay,malondialdehyde assay and lipoprotein agarose gel electrophoresis assay.The normal rat ovarian granulosa cells were isolated and treated with high-density lipoprotein and oxidized high-density lipoprotein isolated from the model rat serum.Cell viability was detected by CCK-8 assay.Cell apoptosis was detected by flow cytometry.The generation of reactive oxygen species was detected by H2DCF-DA staining.The p38 signaling activity was detected by western blot assay.Ovarian granulosa cells were pretreated with reactive oxygen species inhibitors N-acetylcysteine,tetramethylpiperidine(Tempol)and p38 inhibitor SB203580,and then treated with oxidized high-density lipoprotein.Finally,cell apoptosis,reactive oxygen species production and p38 signaling activity were detected. RESULTS AND CONCLUSION:A portion of the high-density lipoprotein from the serum of polycystic ovary syndrome model rats affected oxidative modification.High-density lipoprotein and oxidized high-density lipoprotein isolated from the model rat serum inhibited granulosa cell viability and promoted apoptosis(all P<0.05).They promoted rat granulosa cell reactive oxygen species production and p38 activation(all P<0.05).N-acetylcysteine,Tempol and SB203580 reversed oxidized high-density lipoprotein induced granulosa cell apoptosis(all P<0.05).N-acetylcysteine and Tempol suppressed oxidized high-density lipoprotein-induced p38 activation(all P<0.05).SB203580 did not have a regulatory effect on reactive oxygen species production(P>0.05).In summary,polycystic ovary syndrome can promote partial oxidative modification of high-density lipoprotein.The oxidized high-density lipoprotein promotes rat granulosa cell apoptosis by the activation of the reactive oxygen species-initiated p38 signaling pathway.
ABSTRACT
BACKGROUND:Osteoporosis is often accompanied by sarcopenia and an increased risk of fractures from falls.Recent studies have indicated a close relationship between lipid metabolism and sarcopenia.Abnormal lipid metabolism may directly impact muscle physiological function and metabolism. OBJECTIVE:To investigate the relationship between lipid metabolism and sarcopenia and evaluate their causal relationship using Mendelian randomization. METHODS:Mendelian randomization was used to explore the causal relationship between low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,triglycerides,and muscle mass.Research data from genome-wide association studies were used and a sensitivity analysis was conducted to verify the reliability of the results.Approximate indicators of muscle mass,including trunk lean mass and appendicular lean mass,were used as outcome measures. RESULTS AND CONCLUSION:The study found a negative correlation of low-density lipoprotein cholesterol and triglycerides with muscle mass,while no correlation was observed between high-density lipoprotein cholesterol and muscle mass.The results of the sensitivity analysis indicated a robust causal relationship.Using Mendelian randomization,this study provides evidence of a causal relationship between low-density lipoprotein cholesterol and triglycerides and muscle mass.This finding deepens our understanding of the effects of lipids on sarcopenia and has important clinical implications for the prevention and treatment of sarcopenia and osteoporosis.
ABSTRACT
Objective To investigate the correlation between non-high density lipoprotein cholesterol(non-HDL-C),homocysteine(Hey)levels and cognitive impairment,prognosis in patients with thalamic infarction.Methods Eighty thalamic infarction patients admitted to Puyang People's Hospital from March 2017 to March 2021 were selected as the research sub-jects.According to Montreal cognitive assessment(MoCA)score,the patients were divided into cognitive impairment group(MoCA score＜26,n=35)and cognitive normal group(MoCA score 26-30,n=45).Another 50 healthy individuals who un-derwent physical examinations during the same period were selected as the control group.The serum cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),Hcy levels of all subjects were detected by fully automated biochemical analyzer,and the non-HDL-C levels were calculated.The correlations between non-HDL-C,Hey levels and MoCA scores were analyzed by Pearson correlation analysis,and the diagnostic efficacy of non-HDL-C,Hcy levels for cognitive impairment of patients with tha-lamic infarction was analyzed by receiver operating characteristic curve.According to the modified Rankin scale(mRS)score,the patients with thalamic infarction were divided into good prognosis group(mRS score ≤2,n=50)and poor prognosis group(mRS score 3-6,n=50).The independent risk factors for poor prognosis of patients with thalamic infarction was analyzed by multivariate logistic regression.Results The serum levels of non-HDL-C and Hcy of patients in the cognitive impairment group were significantly higher than those in the cognitive normal group and control group(P＜0.05);there was no significant difference in the serum non-HDL-C,Hcy levels of subjects between the control group and the cognitive normal group(P＞0.05).The non-HDL-C,Hcy levels were negatively correlated with MoCA scores in thalamic infarction patients(P＜0.05).The area under the curve(AUC)of Hcy level in the diagnosis of cognitive impairment was 0.709,the sensitivity was 0.724 and the specificity was 0.630;the AUC of non-HDL-C level in the diagnosis of cognitive impairment was 0.738,the sensitivity was 0.701 and the specificity was 0.870;the AUC of Hey combined with non-HDL-C in the diagnosis of cognitive impairment was 0.769,the sensitivity was 0.758 and the specificity was 0.889.The diagnostic efficacy of Hey combined with non-HDL-C for cognitive impairment was superior to that of non-HDL-C or Hey alone.Atrial fibrillation,elevated levels of non-HDL-C,Hcy and NIHSS score were independent risk factors for poor prognosis of patients with thalamic infarction(P＜0.05).Conclusion The levels of non-HDL-C and Hey are positively correlated with cognitive impairment in patients with thalamic infarction.The levels of non-HDL-C and Hey can be used to diagnose cognitive impairmnent in patients with thalamic infarction,and the combined detection has a better diagnostic effect.Atrial fibrillation,elevated levels of non-HDL-C,Hcy and NIHSS score are independent risk factors for poor prognosis in patients with thalamic infarction.
ABSTRACT
Objective:To investigate the diagnostic value of non-high-density lipoprotein cholesterol (non-HDL-C),ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C), and triglyceride glucose index (TyG) on metabolic syndrome (MS) in adult women.Methods:This was a cross-sectional study. A total of 24 410 adult women who received health examination in health management center of the Affiliated Hospital of Southwest Medical University were selected from January 2019 to December 2021 as subjects. The subjects′ basic information, physical examination results, and laboratory examination data were collected retrospectively. The relationship between non-HDL-C, TG/HDL-C, TyG, and MS in adult women were examined using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) were calculated to evaluate the diagnostic value of each indicator for MS in adult women.Results:Among 24 410 adult females, 800 (3.3%) were found to have MS. After adjusting for age, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, blood uric acid, history of hypertension, history of diabetes, fatty liver, non HDL-C ( OR=1.608), TG/HDL-C ( OR=1.311), TyG ( OR=13.288) were all risk factors for MS in adult women. non-HDL-C, TG/HDL-C, and TyG, as well as their combined AUC of ROC, were 0.795 (95% CI: 0.742-0.776), 0.909 (95% CI: 0.902-0.917), 0.942 (95% CI: 0.937-0.948), and 0.944 (95% CI: 0.937-0.950), respectively. TyG had the highest diagnostic value for MS in adult women among the three indicators, the optimal cutoff value for TyG was 8.237, with a sensitivity of 93.5% and a specificity of 85.5%. Conclusion:non-HDL-C, TG/HDL-C, TyG, as well as their combination, all demonstrate good diagnostic value for MS in adult women.
ABSTRACT
Objective:To investigate the association between high-density lipoprotein cholesterol (HDL-C) and the risk of diabetes mellitus (DM) in Chinese adults.Methods:This study was a secondary analysis of a multicenter, retrospective cohort study using data from the Chinese health screening program in the DATADRYAD database. Between 2010 and 2016, 211833 Chinese adults aged 20 years or older were screened for diabetes at baseline in 32 sites and 11 cities across the country. Baseline HDL-C level was the target independent variable and the risk of DM at follow-up was the dependent variable. Cox proportional hazards regression analysis assessed the independent association between HDL-C levels and the risk of developing DM. In this paper, the generalized Additive Model (GAM) and the smoothing curve fitting method were used to study the nonlinear relationships. In addition, subgroup analyses were conducted to assess the consistency of the correlations among different subgroup and to further validate the reliability of the results.Results:After adjusting for potential confounding factors such as age, sex and body mass index, HDL-C level was positively correlated with the development of diabetes ( HR=1.43, 95% CI: 1.08-1.90, P=0.012). The level of HDL-C showed a non-linear relationship with the risk of DM, and the inflection point was 1.81 mmol/L. The HR (95% CI) of the left and right sides of the inflection point were 0.94 (0.56-1.55) and 2.54 (1.93-3.30), respectively. When HDL-C>1.81 mmol/L, HDL-C was positively correlated with the occurrence of DM. Each 1.00 mmol/L increase in HDL-C increased the risk of diabetes mellitus by 1.54 times ( P<0.001); when HDL-C<1.81 mmol/L, the risk of diabetes decreased by 6% for every 1.00 mmol/L increase in HDL-C ( P=0.798). Subgroup analysis showed that, in the age, male, BMI 24.5-52.7 kg/m 2 subgroups, all the systolic blood pressure subgroups, diastolic blood pressure 69-77 and 78-164 mmHg (1 mmHg=0.133 kPa) subgroups, total cholesterol 0.02-4.26 and 5.00-17.84 mmol/L subgroups, all the triglyceride subgroups, low-density lipoprotein 0-2.42 and 2.99-12.60 mmol/L subgroups, alanine aminotransferase 23.4-1 508.4 U/L subgroups, aspartate transaminase 0-19.7 and 24.8-1 026.2 U/L subgroups, all the urea nitrogen subgroups, creatinine 61.5-76.9, 77.0-1 116.6 μmol/L subgroups, never smoking subgroup, subgroup with frequent alcohol consumption or family history of diabetes mellitus, the effect values of HDL-C and the risk of diabetes mellitus in Chinese adults showed good stability (all HR>1.00). Conclusions:High levels of HDL-C are associated with an increased risk of DM in Chinese adults. When HDL-C is greater than 1.81 mmol/L, HDL-C is positively correlated with DM.
ABSTRACT
Objective To analyze the co-expressed genes in blood lipid metabolism, hyperlipidemia and tacrolimus metabolism and their correlation with blood lipid levels in kidney transplant recipients. Methods Co-expressed genes were screened from Comparative Toxicogenomic Database (CTD). Baseline data of 25 kidney transplant recipients were collected. The expression levels of ATP binding cassette subfamily A member 1(ABCA1), peroxisome proliferator activated receptor γ (PPAR-γ) and glycosylphosphatidylinositol anchored high density lipoprotein binding protein 1 (GPIHBP1) were measured. All recipients were followed up. The concentrations of fasting blood glucose, glycosylated hemoglobin, triglyceride, total protein, albumin, globulin, cholesterol, high-density lipoprotein, low-density lipoprotein and tacrolimus blood concentration were collected at postoperative 1, 3, 6 and 12 months, and the incidence of hyperlipidemia in the recipients was analyzed. The correlation between ABCA1, GPIHBP1, PPAR-γ and clinical indexes was assessed. The diagnostic efficiency of related indexes for hyperlipidemia after kidney transplantation was evaluated. Results Three co-expressed genes including ABCA1, PPAR-γ and GPIHBP1 were screened. ABCA1 was positively correlated with cholesterol level at postoperative 6 months and tacrolimus blood concentration at postoperative 3 months, whereas negatively correlated with fasting blood glucose level at postoperative 3 months (all P<0.05). GPIHBP1 was negatively correlated with preoperative cholesterol and triglyceride levels, whereas positively correlated with tacrolimus blood concentration at postoperative 3 months (all P<0.05). PPAR-γ was negatively correlated with preoperative globulin and low-density lipoprotein levels (both P<0.05). ABCA1, GPIHBP1 and PPAR-γ combined with preoperative globulin and blood glucose level at postoperative 1 and 6 months after operation yielded high diagnostic efficiency for hypertriglyceridemia after kidney transplantation (AUC=0.900). ABCA1, GPIHBP1 and PPAR-γ combined with tacrolimus blood concentrations at postoperative 1 and 6 months and blood glucose level at postoperative 6 months had high diagnostic efficiency for hypercholesterolemia after kidney transplantation (AUC=0.931). Conclusions ABCA1, GPIHBP1 and PPAR-γ are correlated with blood lipid level and tacrolimus blood concentration after kidney transplantation to different degrees. No definite evidence has been supported for predicting hyperlipidemia after kidney transplantation. Immunity improvement and rational blood glucose management may be beneficial factors for hyperlipidemia control.
ABSTRACT
ABSTRACT Background: Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a novel inflammatory biomarker which has been associated with cardiovascular diseases. Objective: To study MHR in patients with psoriasis treated with biological agents. Methods: Between April 2019 and August 2022, MHR was retrospectively evaluated in patients with psoriasis before and 3 months after treatment with infliximab, adalimumab, etanercept, ixekizumab, secukinumab, and ustekinumab in a university hospital in Ankara, Turkey. Results: This study included 128 patients, 53 females and 75 males. 39 (30.5%) patients were treated with infliximab, 26 (20.3%) with adalimumab, 8 (6.3%) with etanercept, 18 (14.1%) with ixekizumab, 12 (9.4%) with secukinumab, and 25 (19.5%) with ustekinumab. The median MHR was 0.0127 (0.0086-0.0165) in females and 0.0146 (0.0119-0.0200) in males (p = 0.011). The median MHR decreased after treatment with adalimumab, ixekizumab, secukinumab, and ustekinumab, whereas it increased after treatment with infliximab and etanercept (p = 0.790, p = 0.015, p = 0.754, p = 0.221, p = 0.276, p = 0.889, respectively). Conclusion: MHR significantly decreased in patients with psoriasis after treatment with ixekizumab. Since high MHR levels have been associated with poor clinical outcomes in patients with cardiovascular diseases, ixekizumab might have a positive impact in the treatment of psoriasis patients who had cardiovascular diseases. We suggest that MHR may be useful both in establishing appropriate biological agent treatment and in the follow-up of patients with psoriasis treated with biological agents.
ABSTRACT
Background: Thyroid diseases are among the most common endocrine disorders worldwide. Thyroid hormones play a key role in regulating the synthesis, metabolism, and mobilization of lipids. Levels of circulating lipids may alter in thyroid dysfunction. Aim and Objectives: The aim of the study was to find out the alterations of lipid levels in thyroid dysfunction. Materials and Methods: The study was designed as cross-sectional observational study and analysis of values was done by significant tests difference in means. 20 patients with hypothyroidism, 20 patients with hyperthyroidism, and 20 normal were participated in the study. Levels of total cholesterol, triglycerides, high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), LDL-C, and LDL/HDL ratio were estimated and compared. Results: In patients with hypothyroidism, there was an increase in total cholesterol, LDL-C, and triglyceride levels and decrease in HDL-C levels. In hyperthyroidism, total cholesterol, triglycerides, LDL-C, VLDL-C, and LDL/HDL ratio were found to be significantly decreased. Conclusion: Altered thyroid function can lead to significant changes in the lipid profile. Hypothyroidism is an important risk factor for heart diseases. Hence, routine screening of thyroid hormones may be of considerable help for early intervention and treatment of thyroid dysfunction-related cardiac disease.
ABSTRACT
Background: Cardiovascular diseases (CVDs) rise first among the causes of death occurring due to non-communicable diseases in the world. The majority of cardiovascular deaths are due to ischemic heart disease and cerebrovascular disease. Among the major risk factors, dyslipidemia is an important risk factor. Hence, the prevention of dyslipidemia results in the prevention of ischemic heart disease. Dyslipidemia can be corrected by drugs but more importantly, it can be prevented by lifestyle modification. Aim and Objectives: Our aim is to observe the impact of yoga on lipid parameters in different age groups. Materials and Methods: We included 54 subjects between the age group of 30 and 60 years for this study. They were categorized into two groups: Group I having ages between 30 and 45 years (n = 23) and Group II having ages between more than 45 years and <60 years (n = 31). The lipid parameters were measured afore of yoga training, at the end of 2 months and after 6 months of yogic practices. Statistical analysis was done using the SPSS version of 20.0. A P value of less than 0.05 is considered as statistically significant. Results: Our study revealed that yoga induces a decrease in total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very LDL cholesterol and an increase in high-density lipoprotein cholesterol in both Group I and Group II subjects which were statistically significant. Conclusion: Yoga tends to improve dyslipidemia, a major risk factor for CVDs. A yoga lifestyle can be considered a preventive measure for CVDs.
ABSTRACT
ABSTRACT In individuals with very low high-density lipoprotein (HDL-C) cholesterol, such as Tangier disease, LCAT deficiency, and familial hypoalphalipoproteinemia, there is an increased risk of premature atherosclerosis. However, analyzes based on comparisons of populations with small variations in HDL-C mediated by polygenic alterations do not confirm these findings, suggesting that there is an indirect association or heterogeneity in the pathophysiological mechanisms related to the reduction of HDL-C. Trials that evaluated some of the HDL functions demonstrate a more robust degree of association between the HDL system and atherosclerotic risk, but as they were not designed to modify lipoprotein functionality, there is insufficient data to establish a causal relationship. We currently have randomized clinical trials of therapies that increase HDL-C concentration by various mechanisms, and this HDL-C elevation has not independently demonstrated a reduction in the risk of cardiovascular events. Therefore, this evidence shows that (a) measuring HDL-C as a way of estimating HDL-related atheroprotective system function is insufficient and (b) we still do not know how to increase cardiovascular protection with therapies aimed at modifying HDL metabolism. This leads us to a greater effort to understand the mechanisms of molecular action and cellular interaction of HDL, completely abandoning the traditional view focused on the plasma concentration of HDL-C. In this review, we will detail this new understanding and the new horizon for using the HDL system to mitigate residual atherosclerotic risk.
ABSTRACT
Background: Stroke is defined as an abrupt onset of a neurologic deficit lasting for more than 24 hours that is attributable to a focal vascular cause. Hyperglycemia and dyslipidemia are often documented in stroke patients. Elevated CRP level is independently associated with the excessive risk of ischemic stroke. Aim and Objectives were to evaluate the glycemic status, lipid profile and c-reactive protein level in stroke patients admitted in a teaching institute of north-east India. Methods: A cross-sectional hospital-based study conducted in the department of medicine, Agartala Government Medical College and GBP hospital, within a period of January 2020 to June 2021. Data were analyzed by SPSS software version 15 using appropriate statistical tests. Results: Among 200 patients of stroke, 50% was found to be pre-diabetic, 40% known diabetic and 10% newly diagnosed diabetic. 60% were hypertensives. Among them, 80% had ischaemic stroke and 20% hemorrhagic stroke. 70% of the patients had hypercholesterolemia, 60% had hypertriglyceridemia. 80% had raised serum LDL and 57% decreased serum HDL. Out of 200 patients, 60% was found to have raised serum CRP level. 55% of ischaemic stroke patients and 5% of hemorrhagic stroke patients had raised CRP level. Conclusions: Prediabetes and newly diagnosed diabetes are highly prevalent in patients with stroke or TIA. As the prevalence of prediabetes is growing rapidly, prediabetes might become one of the most important modifiable therapeutic targets in both primary and secondary prevention. Early detection of dyslipidemia and treatment with drugs along with dietary modifications and lifestyle changes can reduce the risk of stroke. Since, it was a cross-sectional study, these results need to be validated by further long-term prospective studies.
ABSTRACT
【Objective】 To investigate the correlation of monocytes and high-density lipoprotein cholesterol ratio(MHR) and albumin with the severity of coronary artery lesions in patients with unstable angina pectoris. 【Methods】 We enrolled 342 patients with unstable angina pectoris. According to the Gensini score of their coronary angiography results, they were divided into Gensini≤ 20 group, 20<Gensini ≤40 group, and Gensini >40 group. The differences in biochemical indicators between the groups were compared, and the correlation between the different indicators and the Gensini score was analyzed. According to the MHR quartile grouping, there were differences between the comparison groups. LDL-C was divided into subgroups and then subjected to multifactor Logistic regression analysis. 【Results】 MHR differed significantly among low, moderate and high grade lesions (P<0.05). Subgroup analysis showed that in low LDL-C group, Gensini score was positively correlated with MHR(P<0.05), while in high LDL-C group, Gensini score was negatively correlated with albumin(P<0.05). Multivariate Logistic regression analysis showed that the MHR level of patients with high Gensini score was 102.375 times higher than that of patients with low Gensini score(P<0.05). In the group with high LDL-C, the serum albumin level in the group with low Gensini score was 1.431 times that in the group with high Gensini score and 1.218 times that in the group with moderate Gensini score(all P<0.05). 【Conclusion】 In patients with unstable angina pectoris, especially when LDL-C levels are not high, both high MHR and low serum albumin are independent risk factors for the severity of coronary artery disease.
ABSTRACT
【Objective】 To investigate the effects of preoperative lipid metabolism level on the postoperative prognosis of non-muscular invasive bladder cancer (NMIBC). 【Methods】 Clinical data of NMIBC patients who underwent surgical treatment in our hospital during Mar.2014 and May 2021 were retrospectively analyzed. Based on receiver operating characteristic (ROC) curve, the optimal cutoff values of all lipid metabolism indicators were determined and patients were classified accordingly. The independent risk factors for postoperative recurrence were identified with Cox regression model. The survival was analyzed with Kaplan-Meier, and recurrence-free survival (RFS) was compared using log-rank tests. A recurrence risk prediction model was established based on the high-density lipoprotein (HDL) and other clinic pathological factors and the accuracy of prediction was evaluated with the area under the ROC curve (AUC). 【Results】 Cox multivariate analysis showed HDL, tumor number, tumor size and histological grade were independent risk factors for recurrence (P<0.05). Kaplan-Meier analysis showed that RFS was significantly longer in the high-HDL group than in the low-HDL group (P<0.001). Incorporating HDL, tumor number, tumor size, histological grade, and tumor stage into the recurrence risk model, the AUC was 0.706, and internal cross validation showed the AUC was 0.711. 【Conclusion】 Preoperative HDL is an independent risk factor affecting the RFS of patients with NMIBC, and combining it with clinic pathological factors will improve the prediction of tumor recurrence.
ABSTRACT
Objective The correlation between Hb content,monocyte to high density lipoprotein cholesterol ratio(MHR)and post-stroke cognitive impairment(PSCI)was analyzed,and the application value of Hb and MHR in assisting diagnosis and evaluation of PSCI was discussed.Methods The clinical data of first-time stroke patients admitted to the Rehabilitation Department of the Second Affiliated Hospital of Nanjing Medical University from January 2021 to December 2022 were collected.The patients were divided into PSCI group and post-stroke no cognitive impairment(PSNCI)group by using MMSE scores.The differences in serum related indicators between the two groups were analyzed to find the risk factors of PSCI.Results There were a total of 81 stroke patients,including 43 in the PSCI group and 38 in the PSNCI group.There were no statistically significant differences in gender,age,history of hypertension,diabetes,smoking,drinking history,white blood cell count,neutrophil count,lymphocyte count,platelet count,total cholesterol,triglyceride,high density lipoprotein cholesterol and low density lipoprotein cholesterol between the two groups.The Hb content in PSCI group was significantly lower than that in PSNCI group,and the MHR was significantly higher than that in PSNCI group(P＜0.05).Spearman correlation analysis showed that Hb was positively correlated with MMSE score of stroke patients(rs = 0.353,P＜0.05),and MHR was negatively correlated with MMSE score of stroke patients(rs =-0.325,P＜0.05).According to whether PSCI occurred as the dependent variable,the analysis showed that lower Hb content and higher MHR were independent risk factors for PSCI(OR =1.056,95%CI:1.025-1.088,P＜0.05;OR =0.059,95%CI:0.006-0.577,P＜0.05).The area under ROC curve of Hb in predicting PSCI in stroke patients was 0.76(95%CI:0.656-0.865).The area under ROC curve of MHR for predicting PSCI in stroke patients was 0.62(95%CI:0.497-0.742).Conclusions Hb content and MHR are significantly correlated with PSCI.The decrease of Hb content and the increase of MHR are independent risk factors for PSCI.Hb content and MHR have certain reference value for the prediction and diagnosis of PSCI.
ABSTRACT
Objective:To investigate the correlation between serum uric acid/high density lipoprotein cholesterol (URH) and diabetic nephropathy in patients with type 2 diabetes mellitus (T2DM) .Methods:According to urinary albumin creatinine ratio, 171 patients with T2DM were divided into simple T2DM group (group A1), microalbuminuria group (group A2) and macroalbuminuria group (group A3). The general data, HbA1c, biochemical indices were compared, and URH was calculated.Results:The systolic blood pressure, diastolic blood pressure, SUA, TG and URH of A1 group were lower than those of the other two groups [ (129.7±15.78) vs (141.65±16.04) vs (147.31±17.01) mmHg, (78.9±10.71) vs (83.79±10.67) vs (84.61±12.19) mmHg, 291.5 (253.75, 351.25) vs 346 (280, 409) vs 344.5 (274.75, 425.75) μmol/L, 26.12 (19.71,32.96) vs 33.45 (26.55,42.2) vs 33.45 (26.55,42.2) ] ( P<0.05). HDL-C was higher than those of the other two groups [1.19 (1.02,1.29) vs1.02 (0.87,1.21) vs 1.07 (0.93,1.25) mmol/L] ( P<0.05), the course of disease and SCr of group A3 were higher than those of the other two groups [10.5 (7.25, 15) vs 8.5 (4,12) vs 8 (3,11) years; 82.5 (70.57,101.75) vs 66 (52.75,73.75) vs 64 (51, 84) μmol/L ] ( P<0.05), and eGFR was lower than those of the other two groups [91.63 (67.09, 112.21) vs 116.7 (96.6, 142.53) vs 109.85 (85.64, 152.39) ml/min/1.73 m 2] ( P<0.05). There were no significant differences in gender, smoking history, drinking history, age, BMI, TC, LDL-C, BUN, FPG or HbA1c among different groups (P> 0.05). Correlation analysis showed that the course of disease, systolic blood pressure, diastolic blood pressure, TG, SUA, URH were positively correlated with UACR, while HDL-C was negatively correlated with UACR. Logistic regression analysis showed that course of disease was a risk factor for macroproteinuria, while systolic blood pressure and URH were risk factors for microproteinuria and macroproteinuria. ROC curve showed that the AUC value of URH was the highest, and the accuracy rate was 69.3%. Conclusions:URH is closely related to the occurrence of DKD and is a risk factor of DKD. Dynamic monitoring of URH in T2DM patients is helpful for early screening of DKD, which is superior to SUA and HDL-C.
