Abstract
Patients with LMNA mutation‐related heart disease are characterized by conduction abnormalities, ventricular tachyarrhythmias, and high risk of sudden cardiac death with mildly impaired systolic function, often without chamber dilation. Here, we presented three unrelated cases with LMNA mutation exhibited unusual cardiac phenotype of marked LV dilation, significant reduced ejection fraction with reginal wall akinesis, and transmural enhancement with a predilection of lateral wall on cardiovascular magnetic resonance (CMR). These three patients were found to have confirmed pathological LMNA mutations (c.1621C > T, p.R541C and c.1621G > A, p.R541H) at the same location (p.R541) in the tail region of lamin A/C.

Lipids Health Dis 2020; 19:132. [PMID: 32522276 PMCID: PMC7285517 DOI: 10.1186/s12944-020-01311-w] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 06/04/2020] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Remnant cholesterol (RC) can partly explain the residual risk in atherosclerotic cardiovascular disease (ASCVD). A consensus method of measuring RC levels has not been established yet. In clinical practice, RC levels are usually calculated from the standard lipid profile, which are not true RC. Nuclear magnetic resonance (NMR) can measure RC levels directly. This study aimed to characterize RC at fasting and non-fasting states in more details and establish the performance of calculated RC and NMR-measured RC. METHODS Blood samples at fasting state and at 2 h and 4 h postprandial states were collected in 98 subjects. Lipid parameters including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), subfractions 3, 4, and 5 of very low-density lipoprotein cholesterol (VLDL3-C, VLDL4-C, and VLDL5-C, respectively), and intermediate-density lipoprotein cholesterol (IDL-C) were measured by enzymatic method and NMR. RC levels calculated from the standard lipid profile or measured by NMR were referred here as RCe or RCn. RESULTS The RCe and RCn levels were different, but both of them increased after a meal (P < 0.05), especially at 4 h postprandial state. Low correlations were found between RCe and RCn in the 1st, 2nd, and 3rd quartiles of TG, but RCn showed great correlation with RCe in the highest quartile regardless of the fasting or non-fasting state (R = 0.611, 0.536, and 0.535 for 0 h, 2 h, and 4 h, respectively). However, across the 2nd and 3rd quartiles, RCe levels were nearly close to RCn levels. RCe levels tended to overestimate RCn levels in the 1st quartile of TGe levels with median differences of 0.23(- 0.13, 0.63) and underestimate RCn levels with median differences of - 0.23(- 0.33, 0.07) in the highest quartile of TGe levels. CONCLUSIONS RC calculated from the standard lipid profile as TC minus LDL-C minus HDL-C is different from the NMR-measured RC. According to different TG levels, RC could overestimate or underestimate the actual RC level. Developing a consensus clinical method to measure RC levels is necessary, so that results from different studies and platforms can be more directly compared.

Abstract
Cardiac involvement has been reported in patients with COVID-19, which may be reflected by electrocardiographic (ECG) changes. Two COVID-19 cases in our report exhibited different ECG manifestations as the disease caused deterioration. The first case presented temporary SIQIIITIII morphology followed by reversible nearly complete atrioventricular block, and the second demonstrated ST-segment elevation accompanied by multifocal ventricular tachycardia. The underlying mechanisms of these ECG abnormalities in the severe stage of COVID-19 may be attributed to hypoxia and inflammatory damage incurred by the virus.

Abstract
Primary pericardial tumour is an extremely rare disease and an aggressive carcinoma. Its main presenting symptoms are a large recurrent hemorrhagic pericardial effusion. Imaging is the significant tool in the evaluation of pericardial lesions and of tumours. We report the case of a 17-year-old patient with recurrent hemorrhagic pericardial effusion who was diagnosed with primary pericardial fibrosarcoma. However, multiple radiological examinations, including computed tomography and fludeoxyglucose/positron emission tomography-computed tomography ([18F] FDG/PET-CT) suggested the presence of fluid and no sign of tumour. Actually, when a patient presents with recurrent hemorrhagic pericardial effusions, pericardial tumours must be taken into account as part of the differential diagnosis.

Abstract
BACKGROUND The mechanism for an abnormal pattern of triglyceride (TG) metabolism in response to a meal still needs further investigation. Extensive pieces of evidence have shown that apolipoprotein CIII (apoCIII) is a critical modulator of plasma TG metabolism mostly by inhibiting the hydrolysis of TG. Little is known about the role of apoCIII contained in high density lipoprotein (HDL) in plasma TG metabolism after a meal. METHODS Fasting and 4-hour postprandial peripheral venous blood were collected in 91 subjects selected from our hospital. Serum lipid parameters, apoCIII levels and HDL subcomponents were tested by standard laboratory procedures, ELISA, and nuclear magnetic resonance (NMR), respectively. The t-test, and Non-parametric tests were performed to examine differences between groups, Pearson's correlation and multiple regression analysis were used to assess the correlations between apoCIII (HDL-associated or nonHDL-associated) and postprandial TG. RESULTS There was a significant increase in TG after a meal compared to fasting status [155.40(96.70-251.07) mg/dl.vs.118.53(83.38-173.29)mg/dl, p < 0.001]. However, the total apoCIII levels were unchanged before (11.56(7.89-16.22) mg/dl) and after a meal (11.66(7.75-16.02)mg/dl, p = 0.124), while a significant increase in HDL-associated apoCIII (HDL-apoCIII) was observed from fasting (5.25(3.92-7.83)mg/dl) to post-meal (6.46(4.57-8.76)mg/dl, p = 0.001). Unlike nonHDL-apoCIII, HDL-apoCIII was positively correlated with both fasting and postprandial plasma TG in subjects with baseline plasma TG > 118.53 mg/dl (R = 0.503, p < 0.001 for fasting, R = 0.584, p < 0.001 for postprandial). Besides, in the subjects who had an abnormal TG response to a meal, which was defined as postprandial plasma TG increase of>30% compared to baseline TG levels, postprandial HDL-apoCIII was also increased significantly [5.37(3.52-7.02)mg/dl.vs.6.64(4.61-8.86)mg/dl, p = 0.001]. The enrichment of apoCIII in HDL led to changes of TG, cholesterol, free cholesterol, phospholipid and apoAII contents in HDL particles defined by NMR. CONCLUSION Enrichment of apoCIII in HDL particles potentially plays an independent role in postprandial hypertriglyceridemia.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is currently the major cause of chronic liver disease globally. Bile acids (BAs) have emerged as relevant signaling molecules that are associated with NAFLD development. This study was aimed to examine the association of serum total bile acids (TBAs) with NAFLD in a large population of Chinese subjects. Methods This cross sectional study recruited 152,336 participants from the Second Xiangya Hospital, China. NAFLD was diagnosed based on the presence of hepatic steatosis on ultrasonography, without significant alcohol consumption and other known causes for chronic liver disease. A multivariate logistic regression model was used to test for the association of serum TBAs with NAFLD, adjusting for conventional risk factors of NAFLD. Results A total of 27.4% of the participants had NAFLD. Patients with NAFLD had slightly higher TBA levels than those without, 3.4 vs. 3.0 μmol/L (p < 0.001). However, TBA levels were not associated with NAFLD in the multivariate logistic regression model, which adjusted for age, gender and other acknowledged risk factors for NAFLD (OR = 1.00. 95% CI: 1.00–1.00, p = 0.797). Conclusions We found that the serum TBA levels were not associated with NAFLD. Future studies in a large population, focusing on serum BA composition may improve the understating of the role of BAs in NAFLD.

Abstract
PURPOSE To evaluate the effects of metformin on serum lipid profiles in nondiabetic adults through a comprehensive meta-analysis. METHODS In the present meta-analysis, randomized and controlled trials were collected by searching PubMed, Embase, and Cochrane Libraries from inception to April 2019. Compared with placebos, the effects of metformin treatment on lipid profiles in nondiabetic adults were evaluated. RESULTS Forty-seven studies from 45 articles including 5731 participants were enrolled. Pooled results showed that metformin had significant effects on total cholesterol (mean change -6.57 mg/dl; 95% CI -9.66, -3.47; P = 0.000) and LDL-c (mean change -4.69 mg/dl; 95% CI -7.38, -2.00; P = 0.001), but insignificant effects on HDL-c (mean change -4.33 mg/dl; 95% CI -9.62, 0.96; P = 0.109) and triglyceride (mean change -0.85 mg/dl; 95% CI -0.36, 2.06; P = 0.169). Significant heterogeneities were found for all lipid profiles (HDL-c = 85.5%; LDL-c = 59.9%; total cholesterol = 75.3% and triglyceride = 67.1%). Different from the pooled data, in a subgroup analysis, the effect of metformin on triglyceride in patients with polycystic ovarian syndrome (PCOS) was significant with a mean reduction of 8.15 mg/dl. In addition, sensitivity analysis showed that the pooled effects of metformin on serum lipid profiles were stable. Publication bias derived from funnel plots or Begg's tests (P = 0.933, 0.860, 0.904, and 0.567 for HDL-c, LDL-c, total cholesterol, and triglyceride, respectively) was not significant. CONCLUSION This meta-analysis revealed that metformin could reduce total cholesterol and LDL-c in nondiabetic adults. In addition, metformin might exert a triglyceride-lowering effect in nondiabetics with PCOS status.

Abstract
Dyslipidemia, characterized by increased plasma levels of low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), triglyceride (TG), and reduced plasma levels of high-density lipoprotein cholesterol (HDL-C), is confirmed as a hallmark of obesity and cardiovascular diseases (CVD), posing serious risks to the future health of humans. Thus, it is important to understand the molecular metabolism of dyslipidemia, which could help reduce the morbidity and mortality of obesity and CVD. Currently, several exchangeable apolipoproteins, such as apolipoprotein A1 (ApoA1), apolipoprotein A5 (ApoA5), apolipoprotein E (ApoE), and apolipoprotein C3 (ApoC3), have been verified to exert vital effects on modulating lipid metabolism and homeostasis both in plasma and in cells, which consequently affect dyslipidemia. In the present review, we summarize the findings of the effect of exchangeable apolipoproteins on affecting lipid metabolism in adipocytes and hepatocytes. Furthermore, we also provide new insights into the mechanisms by which the exchangeable apolipoproteins influence the pathogenesis of dyslipidemia and its related cardio-metabolic disorders.

Abstract
Background:
The hallmark of obesity is the excessive accumulation of
triglyceride (TG) in adipose tissue. Apolipoprotein A5 (ApoA5) has been shown to
influence the prevalence and pathogenesis of obesity. However, the underlying
mechanisms remain to be clarified.
Methods:
Human adipose-derived mesenchymal stem cells (AMSCs) were treated with
600 ng/ml human recombinant ApoA5 protein. The effect of ApoA5 on intracellular TG
content and adipogenic related factors expression were determined. Furthermore, the
effect of ApoA5 on CIDE-C expression was also observed.
Results:
During the process of adipogenesis, ApoA5 treatment reduced the intracellular
accumulation of lipid droplets and the TG levels; meanwhile, ApoA5 down-regulated the
expression levels of adipogenic related factors, including CCAAT enhancer-binding
proteins α/β (C/EBPα/β), fatty acid synthetase (FAS), and fatty acid-binding protein 4
(FABP4). Furthermore, the suppression of adipogenesis by ApoA5 was mediated
through the inhibition of CIDE-C expression, an important factor which promotes the
process of adipogenesis. However, over-expressing intracellular CIDE-C could lead to
the loss-of-function of ApoA5 in inhibiting AMSCs adipogenesis.
Conclusions:
In conclusion, ApoA5 inhibits the adipogenic process of AMSCs through,
at least partly, down-regulating CIDE-C expression. The present study provides novel
mechanisms whereby ApoA5 prevents obesity via AMSCs in humans.

Abstract
Background Hypertension is a highly prevalent disease and the leading cause of chronic kidney disease (CKD). Metabolic syndrome could also be the risk factor for CKD. We sought to study the association between metabolic syndrome components and the prevalence of CKD in patients with hypertension. Methods We carried out a multi-center cross-sectional study from Apr. 2017- Apr. 2018 in 15 cities in China. Results A total of 2484 patients with hypertension were enrolled. Among them, 56% were male and the average age was 65.12 ± 12.71 years. The systolic BP/diastolic BP was 142 ± 18/83 ± 12 mmHg. Metabolic syndrome components turned out to be highly prevalent in patients with hypertension, ranging from 40 to 58%. The prevalence of chronic kidney disease reached 22.0%. Multi-variate logistic analysis revealed that elevated triglyceride (TG) (OR = 1.81, 95% CI 1.28–2.57, p < 0.01), elevated fasting blood glucose (FBG) (OR = 1.43, 95% CI 1.00–2.07, p = 0.05) and hypertension grades (OR = 1.20, 95% CI 1.00–1.44, p = 0.05) were associated with the prevalence of CKD. In sub-group analysis, elevated TG remained strongly associated with CKD in both diabetes (OR = 2.10, 95%CI 1.22–3.61, p < 0.01) and non-diabetes (OR = 1.53, 95% CI 1.09–2.16, p = 0.01). In sub-group analysis of hypertension grades, there was also a graded trend between elevated TG and CKD from controlled blood pressure (BP) to hypertension grade 2 (OR = 1.81, 95%CI 1.06–3.11, p = 0.03; OR = 1.85, 95%CI 1.00–3.43, p = 0.05; OR = 2.81, 95% CI 1.09–7.28, p = 0.03, respectively). Conclusion Elevated TG, elevated FBG and hypertension grades were significantly associated with the prevalence of CKD in patients with hypertension. Particularly, elevated TG was strongly associated with CKD, independent of diabetes and hypertension grades.

Abstract
Objective To evaluate the effect of 56 ancestry informative single nucleotide polymorphism (aiSNP) genetic markers in the ForenSeqTM DNA Signature Prep Kit on ancestry inference. Methods A total of 85 samples from five populations including Hebei Han population, Inner Mongolia autonomous region Mongolian population, Tibet autonomous region Tibetan population, Xinjiang Uygur autonomous region Uygur population and Nigerian population were collected. The library was constructed with the ForenSeqTM DNA Signature Prep Kit and sequencing was performed based on the MiSeq FGx Forensic Genomics System. Using universal analysis software (UAS) of ForenSeqTM, principal component analysis (PCA), Structure and likelihood ratio method was used on the genotyping data of 56 aiSNP markers, respectively, and the genetic relationships between populations and inference of the origin of ancestors were analyzed. Results Among the five populations tested, the four ethnic populations in China (Hebei Han population, Inner Mongolia autonomous region Mongolian population, Tibet autonomous region Tibetan population and Xinjiang Uygur autonomous region Uygur population) could be significantly distinguished from Nigerian population. Xinjiang Uygur autonomous region Uygur individuals were shown as having mixed origins of ancestors and could be distinguished from the other three Chinese populations. However, the other three populations in China (Hebei Han population, Inner Mongolia autonomous region Mongolian population and Tibet autonomous region Tibetan population) could not be effectively distinguished by the system. Conclusion The 56 aiSNP markers in the ForenSeqTM DNA Signature Prep Kit can make accurate ancestry inference from the intercontinental level, but it is not yet able to distinguish between Chinese subpopulations.

Abstract
Psoriasis is a chronic, systemic, hyper-proliferative immune-mediated inflammatory skin disease. The results of epidemiological investigations have shown that psoriasis affects around 2% of the general population worldwide, and the total number of psoriasis patients is more than 6 million in China. Apart from the skin manifestations, psoriasis has been verified to associate with several metabolic comorbidities, such as insulin resistance, diabetes and obesity. However, the underlying mechanism is still not elucidated. Adipocytes, considered as the active endocrine cells, are dysfunctional in obesity which displays increased synthesis and secretion of adipokines with other modified metabolic properties. Currently, growing evidence has pointed to the central role of adipokines in adipose tissue and the immune system, providing new insights into the effect of adipokines in linking the pathophysiology of obesity and psoriasis. In this review, we summarize the current understanding of the pathological role of adipokines and the potential mechanisms whereby different adipokines link obesity and psoriasis. Furthermore, we also provide evidence which identifies a potential therapeutic target aiming at adipokines for the management of these two diseases.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases in several developed countries, ranging from simple non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH) and cirrhosis. Currently, NAFLD has been confirmed to be associated with dyslipidemia, insulin resistance, and pre-diabetes, which are always grouped together as metabolic syndrome. Fibroblast growth factor 21 (FGF21) plays an important role in liver pathophysiology with multiple metabolic functions. Accumulating evidence has shown that FGF21 could directly modulate lipid metabolism and reduce lipid accumulation in hepatocytes through an insulin-independent pathway, thus suppressing the pathogenesis of NAFLD. Furthermore, treatment with FGF21 could obviously reverse NAFLD and synergistically alleviate obesity and counteract insulin resistance. In this review, we summarize the current knowledge of FGF21 and the evidence of FGF21 as an important regulator in hepatic lipid metabolism. The mechanisms by which FGF21 affects the pathogenesis of NAFLD would also be proposed for the further understanding of FGF21.

Abstract
As aging is becoming a global phenomenon, the burden of population aging is increasing rapidly, and is soon expected to be the highest in low-and middle-income countries. China represents the world's largest population, and will face the largest number of older individuals, while the economy still remains developing. There is an urgent need to address the negative consequences of aging such as disability, that creates a myriad of challenges, including financial burden to the economy. In order to achieve successful aging-i.e., aging without being frail or disabled, the traditional healthcare model based on a disease-centered approach is not enough, but require a more holistic course. Here, we briefly outline the current scenario of aging and disability in the Chinese older population, its impact and challenges. We strongly believe that public health initiatives centered on frailty, a clinically distinguishable state of extreme vulnerability in older adults, could be the most relevant approach to meet the current needs of the aging population. Such initiatives are immediately needed to reshape the existing model of geriatric healthcare, to promote healthy aging and to reduce the burden of disability in the Chinese population.

Clin Chim Acta 2019; 496:48-54. [PMID: 31255567 DOI: 10.1016/j.cca.2019.06.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 06/19/2019] [Accepted: 06/26/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND Guidelines recommended non-high density lipoprotein cholesterol (non-HDL-C) as a co-primary target, and set non-HDL-C goals as 30 mg/dl higher than low-density lipoprotein cholesterol (LDL-C) goals. However, the value is largely uncertain in Chinese patients. METHODS We assigned non-HDL-C values at the same percentiles correspondent to LDL-C goals for patients from the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) Project. We calculated the differences between non-HDL-C and LDL-C and proposed appropriate adding values according to LDL-C and TG concentrations. RESULTS Among 73,495 patients, 17.7% used lipid-lowering agents before admission. Of these, 27.2% achieved LDL-C <70 mg/dl while 39.4% achieved non-HDL-C <100 mg/dl. The mean difference between non-HDL-C and LDL-C was 23.2 mg/dl, which could be affected by LDL-C and TG concentrations. Importantly, of patients with LDL-C concentrations ≤100 mg/dl, the mean differences were 19.1 mg/dl in patients with TG ≤150 mg/dl and 24.6 mg/dl in patients with TG >150 mg/dl. CONCLUSIONS There are significant differences between LDL-C and non-HDL-C in Chinese ACS patients. For secondary prevention, on average, the adding values should be 20 mg/dl for patients with TG ≤150 mg/dl and 25 mg/dl for patients with TG >150 mg/dl when LDL-C goals of 70 mg/dl is achieved.
