Impact of metabolic syndrome components on clinical outcomes in hypertriglyceridemia-induced acute pancreatitis

BACKGROUND The incidence of hypertriglyceridemia(HTG)-induced acute pancreatitis(AP)is steadily increasing in China,becoming the second leading cause of AP.Clinical complications and outcomes associated with HTG-AP are generally more severe than those seen in AP caused by other etiologies.HTG-AP is closely linked to metabolic dysfunction and frequently coexists with metabolic syndrome or its components.However,the impact of metabolic syndrome components on HTGAP clinical outcomes remains unclear.AIM To investigate the impact of metabolic syndrome component burden on clinical outcomes in HTG-AP.METHODS In this retrospective study of 255 patients diagnosed with HTG-AP at the First Affiliated Hospital of Guangxi Medical University,we collected data on patient demographics,clinical scores,complications,and clinical outcomes.Subsequently,we analyzed the influence of the presence and number of individual metabolic syndrome components,including obesity,hyperglycemia,hypertension,and low high-density lipoprotein cholesterol(HDL-C),on the aforementioned parameters in HTG-AP patients.RESULTS This study found that metabolic syndrome components were associated with an increased risk of various complications in HTG-AP,with low HDL-C being the most significant risk factor for clinical outcomes.The risk of complications increased with the number of metabolic syndrome components.Adjusted for age and sex,patients with highcomponent metabolic syndrome had significantly higher risks of renal failure[odds ratio(OR)=3.02,95%CI:1.12-8.11)],SAP(OR=5.05,95%CI:2.04-12.49),and intensive care unit admission(OR=6.41,95%CI:2.42-16.97)compared to those without metabolic syndrome.CONCLUSION The coexistence of multiple metabolic syndrome components can synergistically worsen the clinical course of HTGAP,making it crucial to monitor these components for effective disease management.

Higher testosterone levels are associated with increased highdensity lipoprotein cholesterol in men with cardiovascular disease： results from the Massachusetts Male Aging Study

Aim： To study the relationship between circulating androgens （total testosterone [TT], free testosterone [IT] and dihydrotestosterone [DHT]） and high-density lipoprotein cholesterol （HDL-C） in men with and without cardiovascular disease （CVD）. Methods： Cross-sectional analyses included 1 661 baseline samples from the Massachusetts Male Aging Study （MMAS）, a population-based cohort of men ages 40-70 years. Serum hormones were measured by radioimmunoassay and HDL-C was determined following precipitation of the lower density lipoproteins. CVD was determined by self-report. Analyses were performed using multiple linear regression. Results： TT and HDL-C were positively correlated in the entire sample （r = 0.11, P = 0.0001）. After adjusting for confounders, we found this relationship was mostly limited to the 209 men with CVD. Among men with CVD, TT （P = 0.0004）, iT （P = 0.0172） and DHT （P = 0.0128） were all positively correlated with HDL-C, whereas in men without CVD only TT correlated with HDL-C （P = 0.0099）. Conclusion： Our results suggest that if androgens contribute to CVD in middle-aged men, the effect is not related to a suppressive effect of endogenous T on HDL-C. （Asian JAndrol 2008 Mar; 10： 193-200）

High-density Lipoprotein Cholesterol and In-hospital Mortality in Patients with Acute Aortic Dissection

The association between high-density lipoprotein cholesterol（HDL-C） and mortality in patients with acute aortic dissection（AAD） is unclear. From January 2007 to January 2014, a total of 928 consecutive AAD patients who were admitted within 48 h after the onset of symptoms were enrolled in the study. Patients were divided into two groups according to whether serum HDL-C level was below the normal lower limit or not. The Cox proportional hazard regression model was used to identify the predictive value of HDL-C for in-hospital mortality in patients with AAD. As compared with normal HDL-C group（n=585）, low HDL-C group（n=343） had lower levels of systolic blood pressure and hemoglobin and higher levels of leukocyte, alanine aminotransferase, blood glucose, blood urea nitrogen, creatinine and urea acid. Low HDL-C group had significantly higher in-hospital mortality than normal HDL-C group（21.6% vs. 12.6%, log-rank=10.869, P=0.001）. After adjustment for baseline variables including demographics and biologic data, the increased risk of in-hospital mortality in low HDL-C group was substantially attenuated and showed no significant difference（adjusted hazard ratio, 1.23; 95% confidence interval, 0.86–1.77; P=0.259）. Low HDL-C is strongly but not independently associated with in-hospital mortality in patients with AAD.

Relationship of Circulating High-Density Lipoprotein Cholesterol and Anemia

Circulating level of low HDLC （high-density lipoprotein cholesterol） represents a common critical risk factor for IHD （ischemic heart disease） and may further aggravate the condition in anemic subjects, as the presence of anemia itself is a threat to cardiovascular consequences. To investigate the relationship of circulating HDLC with anemia, first we determined the levels of total hemoglobin （Hb） in a total of 301 subjects （male, n = 158; female, n = 143） randomly, and then examined the circulating levels of HDLC in fasting condition. Age of the study subjects was 47.9 ~ 16.6 （mean ＋ SD） years. Both the male and female subjects were divided into three groups according to their levels of Hb. The relationship of circulating levels of HDLC with the levels of total Hb was statistically analyzed. In case of the male subjects, we found that the levels of HDLC differed significantly among the three groups with different levels of Hb （P = 0.0233） and decrease in the levels of HDLC correlated significantly with the gradual decrease of total Hb level （r = 0.2504; P = 0.0015）. In female subjects, we observed a similar trend of difference among the three groups （P = 0.0685）. However, decrease in the levels of HDLC correlated significantly with the gradual decrease of Hb level （r = 0,2199; P = 0.0083）. Altogether, this study demonstrates that decrease in the circulating HDLC is related to the gradual decrease of Hb level. This study also indicates that circulating level of HDLC may be influenced by the level of total Hb and reveals the cardiovascular risks in anemia as well.

A Possible Mechanism Linking Hyperglycemia and Reduced High-density Lipoprotein Cholesterol Levels in Diabetes

This study investigated the role of glucose in the biogenesis of high-density lipoprotein cholesterol(HDL-C).Mouse primary peritoneal macrophages were harvested and maintained in Dulbecco’s modified Eagle’s medium(DMEM) containing glucose of various concentrations.The cells were divided into 3 groups in terms of different glucose concentrations in the cultures:Control group(5.6 mmol/L glucose),high glucose concentration groups(16.7 mmol/L and 30 mmol/L glucose).ATP-binding cassette transporter A1(ABCA1) mRNA expression in the macrophages was detected by semi-quantitative RT-PCR 24,48 and 72 h after glucose treatment.The results showed that ABCA1 mRNA expression in the 16.7 mmol/L glucose group was not significantly different from that in the control group at all testing time points(P>0.05 for each).In the 30 mmol/L glucose group,macrophage ABCA1 mRNA expression was not changed significantly at 24 h(P=0.14),but was substantially decreased by 40.4% at 48 h(P=0.009) and by 48.1% at 72 h(P=0.015) as compared with that in the control group.It was concluded that ABCA1 is of vital importance for HDL-C biogenesis.High glucose may hamper HDL-C biogenesis by decreasing ABCA1 expression,which contributes to low HDL-C level in diabetes.

High Density Lipoprotein Phospholipids as a Marker of Coronary Heart Disease of Shen-Yang Deficiency Syndrome

Objective: To seek a new biochemical index for diagnosis of coronary heart disease (CHD) of shen-Yang deficiency syndrom (CHD-SYD). Methods: Sixty-one patients with CHD were divided into 3 groups according to their TCM Syndrome type, 10 patients in the group without Xin-Qi deficiency (Group A), 25 in the group with Xin-Qi deficiency but without Shen-Yang deficiency (Group B) and 26 in the group both with Xin-Qi deficiency and Shen-Yang deficiency (Group C). Levels of 17-hydroxy-corticoste-roid in urine (urinary 17-OHCS) per 24 hrs, and serum level of high density lipoprotein cholesterol (HDL-C) and high density lipoprotein phospholipid (HDL-PL) in them were determined in synchrostep and compared with those in the control group of 23 healthy aged persons, urinary 17-OHCS per 24 hrs was taken as the diagnostic standard to screen a new index for diagnosis of Shen-Yang deficiency Syndrome, and preliminary appraisal to the index was made. Results: Serum HDL-PL in the CHD-SYD patients( Group C) was 616+157 mg/L, which was obviously lower than that in the patients of Group A and B. With low HDL-PL(<650 mg/L) used as the index to diagnose CHD-SYD, the sensitivity was 73%, the specificity 86% and the accuracy 80%. Conclusion: HDL-PL <650 mg/L could be adopted as an index for CHD-SYD diagnosis, which is simple and practical.

Research progress of monocyte/high density lipoprotein ratio in cardiovascular diseases

In recent years,monocyte to high density lipoprotein cholesterol ratio(MHR)has attracted wide attention as a new marker of inflammatory response.This indicator includes two aspects:inflammatory response and lipid accumulation,which are the two most basic characteristics of Atherosclerosis(AS).AS is closely related to the occurrence of Cardiovascular diseases(CVD).A large number of existing studies have confirmed that MHR is an inflammatory marker that can dynamically reflect the trend of inflammation,can reflect the chronic inflammatory response in blood vessels,and can evaluate the occurrence,development and prognosis of cardiovascular disease in a non-invasive manner.This article reviews recent studies on the role of monocytes and high-density lipoproteins in chronic inflammation of blood vessels,as well as the current status of research on MHR and cardiovascular disease in the light of recent literature.

Lipoprotein in cholesterol transport: Highlights and recent insights into its structural basis and functional mechanism

Lipoproteins are protein-lipid macromolecular assemblies which are used to transport lipids in circulation and are key targets in cardiovascular disease （CVD）. The highly dynamic lipoprotein molecules are capable of adopting an array of conformations that is crucial to lipid transport along the cholesterol transport pathway, among which high-density lipopro- tein （HDL） and low-density lipoprotein （LDL） are major players in plasma cholesterol metabolism. For a more detailed illustration of cholesterol transport process, as well as the development of therapies to prevent CVD, here we review the functional mechanism and structural basis of lipoproteins in cholesterol transport, as well as their structural dynamics in the plasma lipoprotein （HDL and LDL） elevations, in order to obtain better quantitative understandings on structure-function relationship of lipoproteins. Finally, we also provide an approach for further research on the lipoprotein in cholesterol transport.

High-density lipoprotein endocytosis in endothelial cells

AIM: To describe the way stations of high-density lipoprotein(HDL) uptake and its lipid exchange in endothelial cells in vitro and in vivo. METHODS: A combination of fluorescence microscopy using novel fluorescent cholesterol surrogates and electron microscopy was used to analyze HDL endocytosis in great detail in primary human endothelial cells. Further, HDL uptake was quantified using radio-labeled HDL particles. To validate the in vitro findings mice were injected with fluorescently labeled HDL and particle uptake in the liver was analyzed using fluorescencemicroscopy. RESULTS: HDL uptake occurred via clathrin-coated pits, tubular endosomes and multivesicular bodies in human umbilical vein endothelial cells. During uptake and resecretion, HDL-derived cholesterol was exchanged at a faster rate than cholesteryl oleate, resembling the HDL particle pathway seen in hepatic cells. In addition, lysosomes were not involved in this process and thus HDL degradation was not detectable. In vivo, we found HDL mainly localized in mouse hepatic endothelial cells. HDL was not detected in parenchymal liver cells, indicating that lipid transfer from HDL to hepatocytes occurs primarily via scavenger receptor, class B, type Ⅰ mediated selective uptake without concomitant HDL endocytosis. CONCLUSION: HDL endocytosis occurs via clathrincoated pits, tubular endosomes and multivesicular bodies in human endothelial cells. Mouse endothelial cells showed a similar HDL uptake pattern in vivo indicating that the endothelium is one major site of HDL endocytosis and transcytosis.

Triglycerides and ratio of triglycerides to high-density lipoprotein cholesterol are better than liver enzymes to identify insulin resistance in urban middle-aged and older non-obese Chinese without diabetes

Background Insulin resistance （IR） plays an important pathophysiological role in the development of diabetes,dyslipidemia,hypertension,and cardiovascular disease.Moreover,IR can occur even in non-obese people without diabetes.However,direct detection of IR is complicated.In order to find a simple surrogate marker of IR early in nonobese people,we investigate the association of commonly-used biochemical markers （liver enzymes and lipid profiles） with IR in urban middle-aged and older non-obese Chinese without diabetes.Methods This cross-sectional study included 1 987 subjects （1 473 women）.Fasting blood samples were collected for measurement of glucose,insulin,liver enzymes,lipid profiles and creatinine.Subjects whose homeostasis model of assessment-IR （HOMA-IR） index values exceeded the 75th percentile （2.67 for women and 2.48 for men） of the population were considered to have IR.The area under the receiver operating characteristic curve （ROC） was used to compare the power of potential markers in identifying IR.Results Triglycerides （TG） and ratio of TG to high-density lipoprotein cholesterol （TG/HDL-C） discriminated IR better than other indexes for both sexes; areas under the receiver operating characteristic （ROC） curves （AUC） values were 0.770 （95％ confidence interval 0.733-0.807） and 0.772 （0.736-0.809）,respectively,for women and 0.754 （0.664-0.844）and 0.756 （0.672-0.840）,respectively,for men.To identify IR,the optimal cut-offs for TG and TG/HDL-C ratio were 1.315 mmol/L （sensitivity 74.3％,specificity 71.0％） and 0.873 （sensitivity 70.1％,specificity 73.4％）,respectively,for women,and 1.275 mmol/L （sensitivity 66.7％,specificity 74.4％） and 0.812 （sensitivity 75.8％,specificity 69.2％）,respectively,for men.Conclusion TG and TG/HDL-C ratio could be used to identify IR in urban middle-aged and older non-obese Chinese without diabetes.

An Analysis of Health Factors Affecting Employees’ Absenteeism: Influences of HDL Cholesterol and Blood Sugar Levels

Background: Workers’ health condition is an important issue. It affects not only the well-being of workers but also the firms and society as a whole through medical costs and productivity losses due to absenteeism and presenteeism. Data and Methods: Data were obtained from 1136 employees at an operational site of a large corporation. The dataset contained both medical checkups and working record information. Health factors affecting long-term absence (over three days in three months) were analyzed. Logistic regression models and the procedure for selecting proper covariates based on likelihood test statistics and the Akaike information criterion were used. Results: Among health factors, high-density lipoprotein cholesterol (HDL-C) and blood sugar levels were important in the selected model. For HDL-C, the odds ratio (OR) based on one standard deviation difference was 0.75 with a 95% confidence interval (CI) of 0.59 - 0.95. For blood sugar, the OR was 1.20 with a 95% CI of 1.01 - 1.42. Improving HDL-C and blood sugar levels would reduce long-term absence by 25% and 20%, respectively. Conclusion: Controlling HDL-C and blood sugar levels is important to reduce long-term absenteeism. These factors can be improved by modifying eating habits. Since the operational site has its own company cafeterias, which most employees use, nutritional intervention is relatively easy with little or no cost. It may be worthwhile to implement nutritional intervention, especially for patients with low HDL-C or high blood sugar levels. Limitations: The results of this study were based on one operational site of a corporation. The employees were mainly operators working inside the building. The results may be different from other types of jobs and working conditions, such as fieldwork. Analyses of different types of jobs and working conditions are necessary.

目的探讨非高密度脂蛋白胆固醇(non-HDL-C)、同型半胱氨酸(Hcy)水平与丘脑梗死患者认知障碍及预后的相关性。方法选择2017年3月至2021年3月濮阳市人民医院收治的丘脑梗死患者80例为研究对象。根据蒙特利尔认知评估(MoCA)量表得分将患者分为认知障碍组(MoCA评分<26分,n=35)和认知正常组(MoCA评分26~30分,n=45);另选择同期健康体检者50例作为对照组。采用全自动生物化学分析仪检测所有受试者血清中总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、Hcy水平,并计算non-HDL-C水平。采用Perason相关分析non-HDL-C、Hcy水平与MoCA评分的相关性,受试者操作特征曲线分析non-HDL-C、Hcy水平诊断丘脑梗死患者认知障碍的效能。根据改良Rankin量表(mRS)评分将丘脑梗死患者分为预后良好组(mRS评分≤2分,n=50)和预后不良组(mRS评分3~6分,n=50),采用多因素logistic回归分析丘脑梗死患者预后不良的独立危险因素。结果认知障碍组患者血清non-HDL-C、Hcy水平显著高于认知正常组和对照组(P<0.05);对照组与认知正常组受试者血清non-HDL-C、Hcy水平比较差异无统计学意义(P>0.05)。丘脑梗死患者non-HDL-C、Hcy水平与MoCA评分均呈负相关(P<0.05)。Hcy水平诊断认知障碍的曲线下面积(AUC)为0.709,敏感度为0.724,特异度为0.630;non-HDL-C水平诊断认知障碍的AUC为0.738,敏感度为0.701,特异度为0.870;Hcy联合non-HDL-C诊断认知障碍的AUC为0.769,敏感度为0.758,特异度为0.889。Hcy联合non-HDL-C诊断认知障碍的效能优于non-HDL-C、Hcy单独诊断。心房颤动及non-HDL-C、Hcy水平和NIHSS评分升高是丘脑梗死患者预后不良的独立危险因素(P<0.05)。结论non-HDL-C、Hcy水平均与丘脑梗死患者认知障碍呈正相关,non-HDL-C、Hcy水平可用于诊断丘脑梗死患者认知障碍,且联合检测诊断效果更优。心房颤动及non-HDL-C、Hcy水平和NIHSS评分升高是丘脑梗死患者预后不良的独立危险因素。

MHR、NLR与急性缺血性脑卒中静脉溶栓患者预后的关系

目的探究单核细胞与高密度脂蛋白胆固醇比值(MHR)、中性粒细胞与淋巴细胞比值(NLR)与急性缺血性脑卒中静脉溶栓患者预后的关系。方法回顾性分析2021年1月—2022年12月蚌埠第一人民医院收治的110例急性缺血性脑卒中患者的病历资料。收集患者的基线资料,根据患者90 d时电话随访结果分为预后良好组和预后不佳组。采用多因素逐步Logistic回归模型分析影响患者预后的高危因素;绘制受试者工作特征(ROC)曲线评估MHR、NLR对急性缺血性脑卒中静脉溶栓患者预后的预测效能。结果110例急性缺血性脑卒中患者预后良好76例(69.09%),预后不佳34例(30.91%)。预后不佳组患者的白细胞计数、美国国立卫生研究院卒中量表(NIHSS)评分、中性粒细胞计数、单核细胞计数、MHR、NLR高于预后良好组(P<0.05),高密度脂蛋白胆固醇、淋巴细胞计数低于预后良好组(P<0.05)。多因素逐步Logistic回归分析结果显示,白细胞计数[O^R=4.125(95%CI:1.409,12.068)]、NIHSS评分[O^R=4.860(95%CI:1.662,14.218)]、高密度脂蛋白胆固醇[O^R=0.234(95%CI:0.080,0.685)]、中性粒细胞计数[O^R=3.991(95%CI:1.364,11.676)]、单核细胞计数[O^R=3.529(95%CI:1.206,10.325)]、淋巴细胞计数[O^R=0.248(95%CI:0.085,0.724)]、MHR[O^R=3.445(95%CI:1.178,10.079)]、NLR[O^R=4.043(95%CI:1.382,11.829)]均为急性缺血性脑卒中患者预后不佳的影响因素(P<0.05)。ROC曲线分析结果显示,MHR、NLR单一及联合预测急性缺血性脑卒中患者预后的敏感性分别为82.35%(95%CI:0.648,0.926)、79.41%(95%CI:0.616,0.907)、85.29%(95%CI:0.682,0.944);特异性分别为76.32%(95%CI:0.649,0.850)、73.92%(95%CI:0.641,0.835)、88.16%(95%CI:0.782,0.941);曲线下面积分别为0.790(95%CI:0.712,0.869)、0.801(95%CI:0.732,0.891)、0.875(95%CI:0.810,0.940)。结论MHR、NLR水平与急性缺血性脑卒中患者的预后密切相关,且可用于预测患者的短期预后。
