Abstract
An imbalance in coagulation is associated with cardiovascular events. For prevention and treatment, anticoagulants, currently mainly xabans and gatrans, are used. The purpose of the present study was to provide a head-to-head comparison since there are no studies directly evaluating these novel anticoagulants. An additional aim was to find whether selected anthropological and biochemical factors can affect their anticoagulant properties as they are used in fixed doses. In this cross-sectional study, blood from 50 generally healthy donors was collected, and coagulation responses to dabigatran, argatroban, rivaroxaban, and apixaban, at a concentration of 1 μM, were analyzed. Heparin was used as a positive control. Prothrombin time (PT) expressed as international normalized ratio (INR) and activated partial thromboplastin time (aPTT) were measured and compared. Rivaroxaban was the most active according to PT/INR while argatroban according to aPTT. The ex vivo anticoagulant effect measured by INR correlated inversely with body mass index (BMI) in all four anticoagulants tested. Shortening of aPTT was associated with higher cholesterol and triglyceride levels. No sex-related differences were observed in response to the anticoagulant treatments. As this was an ex vivo study and pharmacokinetic factors were not included, the influence of BMI is of high therapeutic importance.

Zhu L, Fang S, Zhang Y, Sun X, Yang P, Lu W, Yu L. Effects of sn-2 Palmitic Triacylglycerols and the Ratio of OPL to OPO in Human Milk Fat Substitute on Metabolic Regulation in Sprague-Dawley Rats. Nutrients 2024; 16:1299. [PMID: 38732546 PMCID: PMC11085268 DOI: 10.3390/nu16091299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/23/2024] [Accepted: 04/25/2024] [Indexed: 05/13/2024] Open
Abstract
In this study, the influence of total sn-2 palmitic triacylglycerols (TAGs) and ratio of 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (OPL) to 1,3-dioleoyl-2-palmitoylglycerol (OPO) in human milk fat substitute (HMFS) on the metabolic changes were investigated in Sprague-Dawley rats. Metabolomics and lipidomics profiling analysis indicated that increasing the total sn-2 palmitic TAGs and OPL to OPO ratio in HMFS could significantly influence glycine, serine and threonine metabolism, glycerophospholipid metabolism, glycerolipid metabolism, sphingolipid metabolism, bile acid biosynthesis, and taurine and hypotaurine metabolism pathways in rats after 4 weeks of feeding, which were mainly related to lipid, bile acid and energy metabolism. Meanwhile, the up-regulation of taurine, L-tryptophan, and L-cysteine, and down-regulations of lysoPC (18:0) and hypoxanthine would contribute to the reduction in inflammatory response and oxidative stress, and improvement of immunity function in rats. In addition, analysis of targeted biochemical factors also revealed that HMFS-fed rats had significantly increased levels of anti-inflammatory factor (IL-4), immunoglobulin A (IgA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-px), and decreased levels of pro-inflammatory factors (IL-6 and TNF-α) and malondialdehyde (MDA), compared with those of the control fat-fed rats. Collectively, these observations present new in vivo nutritional evidence for the metabolic regulatory effects of the TAG structure and composition of human milk fat substitutes on the host.

Comparison of Different Vascular Biomarkers for Predicting In-Hospital Mortality in Severe SARS-CoV-2 Infection. Microorganisms 2024; 12:229. [PMID: 38276214 PMCID: PMC10820061 DOI: 10.3390/microorganisms12010229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/05/2024] [Accepted: 01/16/2024] [Indexed: 01/27/2024] Open
Abstract
Severe SARS-CoV-2 elicits a hyper-inflammatory response that results in intravascular inflammation with endothelial injury, which contributes to increased mortality in COVID-19. To predict the outcome of severe SARS-CoV-2 infection, we analyzed the baseline level of different biomarkers of vascular disorders in COVID-19 subjects upon intensive care unit (ICU) admission and prior to any vaccination. A total of 70 severe COVID-19 patients (37 survivors and 33 non-survivors) were included with 16 age- and sex-matched controls. Vascular dysfunction was monitored via soluble VCAM-1, E-selectin, ACE2 and Lp-PLA2, while abnormal platelet activation was evaluated by soluble P-selectin and CD40L in parallel. These results were correlated with routine laboratory parameters and disease outcomes. Among these parameters, VCAM-1 and ACE2 showed significantly higher serum levels in COVID-19 patients with early death vs. convalescent subjects. VCAM-1 was significantly correlated with the Horowitz index (r = 0.3115) and IL-6 (r = 0.4599), while ACE2 was related to E-selectin (r = 0.4143) and CD40L (r = 0.2948). Lp-PLA2 was altered in none of these COVID-19 subcohorts and showed no relationship with the other parameters. Finally, the pre-treatment level of VCAM-1 (≥1420 ng/mL) and ACE2 activity (≥45.2 μU/mL) predicted a larger risk for mortality (Log-Rank p = 0.0031 and p = 0.0117, respectively). Vascular dysfunction with endothelial cell activation is linked to lethal COVID-19, and highly elevated soluble VCAM-1 and ACE2 at admission to ICU may predict unfavorable outcomes.

Abstract
Purpose This paper aims to study the relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2) and GDM (gestational diabetes mellitus) by detecting Lp-PLA2 level and its gene polymorphism. Patients and Methods From January to June 2022, 82 GDM patients treated in our hospital were included as an experimental group, and 89 healthy pregnant women during the same period were selected as the control group. Lp-PLA2 concentration and TG, TC, HDL-C, and LDL-C levels were tested with specialized instruments in clinical laboratories. The PLA2G7 gene polymorphisms (rs1805017, rs1805018, and rs76863441) were detected by fluorescent probe method and sequencing. Results Lp-PLA2 concentration was significantly higher in GDM group than control group (P<0.05). Among three polymorphism loci of PLA2G7 gene (rs1805017, rs1805018, and rs76863441) the significant associations were only found in GT genotype of rs76863441 loci (P<0.05). Conclusion Pregnant women with high levels of Lp-PLA2 concentration are more likely to develop GDM, especially those with PLA2G7 rs76863441 polymorphism. Lp-PLA2 concentration and PLA2G7 rs1805017 polymorphism may be a novel marker for GDM diagnosis and prediction.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 878:163194. [PMID: 37001669 DOI: 10.1016/j.scitotenv.2023.163194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/07/2023] [Accepted: 03/27/2023] [Indexed: 05/13/2023]
Abstract
6-Benzylaminopurine (6-BA) is ubiquitous in agricultural production and is accessible to humans through diets. The modulation of lipid metabolism by 6-BA has been previously demonstrated in plants and oleaginous microorganisms. Therefore, whether it alters lipid homeostasis in other living organisms requires further investigation. In this study, doses ≥10 mg 6-BA/L caused malformation of the yolk sac, steatosis, and other hepatopathies in zebrafish larvae. Exposure to 25 mg 6-BA/L resulted in increased levels of triglyceride and total cholesterol. Results of transcriptomic analysis indicated that 6-BA alters genes associated with fatty acid and glycerophospholipid metabolism. Among them, the expression levels of hmgcra, elovl7b, and apobb.2 were downregulated, whereas those of lpcat3, bco1l, cyp7al, fabp1b.1, elp6, pde6ha, apoa4b.2_2, sgk1, dgkaa, and mogat2 were upregulated. Correspondingly, a study of the metabolome identified lysophosphatidylcholine (LPC) as the major differentially expressed metabolite in response to 6-BA treatment. Therefore, abnormal accumulation of LPCs and dyshomeostasis of glycerophospholipid metabolism were identified as potential mechanisms causing the toxicity of 6-BA, which should be assessed to understand the risks of 6-BA and the products contaminated by it. ENVIRONMENTAL IMPLICATION: 6-Benzylaminopurine (6-BA), an important residue in "toxic bean sprouts," is ubiquitous in agricultural production and is common in typical diets. Its regulation of lipid metabolism has been demonstrated in plants and oleaginous microorganisms. Whether it alters lipid homeostasis in other organisms and the underlying mechanisms remain largely unknown. The worldwide use of 6-BA and the potential exposure of humans have aroused public attention owing to its hazardous effects; thus, its hazardous effects, particularly those on lipid homeostasis, deserve careful clarification.

Abstract
Background Laparoscopic hepatectomy with a small incision, light abdominal wall trauma and rapid postoperative recovery has been widely used in the surgical treatment of benign liver diseases. However, the occurrence of complications, such as deep-vein thrombosis, associated with laparoscopic techniques has raised concerns. This study aimed to investigate the factors influencing the development of a hypercoagulable state in patients following laparoscopic hepatic haemangioma resection. Materials and Methods Between 2017 and 2019, 78 patients to be treated by laparoscopic hepatic haemangioma resection were selected prospectively for the study. The differences in relevant clinical factors between patients with and without blood hypercoagulability at 24 h after surgery were compared, and the factors influencing the development of blood hypercoagulability after surgery were analysed. Results The study included 78 patients, split into the hypercoagulable group (n = 27) and nonhypercoagulable group (n = 51). Compared with patients who did not develop blood hypercoagulability, patients who did had significantly higher preoperative levels of fibrinogen (Fib), D-dimer (D-Di), fibrinogen degradation products (FDP), platelet count (PLT), low-density lipoprotein cholesterol (LDL-C) and history of hyperlipidaemia whereas high-density lipoprotein cholesterol (HDL-C) levels were significantly lower (P < 0.05.) in hypercoagulable group. Univariate and multifactorial logistic regression analyses showed that a history of hyperlipidaemia, Fib ≥3.83 g/L, D-Di ≥9.12 μg/ml, FDP ≥14.64 μg/ml, PLT ≥292 × 109/L, HDL-C ≥1.25 mmol/L and LDL-C ≥2.03 mmol/L was the most common independent risk factors for the development of a hypercoagulable state of blood in patients after laparoscopic hepatic haemangioma resection (P < 0.05). Conclusion For patients undergoing laparoscopic hepatic haemangioma resection, attention should be paid to the development of a hypercoagulable state in those with the risk factors described in this study.

Abstract
BACKGROUND AND PURPOSE Early identification of cerebrovascular atherosclerotic ischemic stroke is necessary for accurate treatment and clinical research. AIMS To identify novel predictors and build a predictive model of ischemic strokes due to cerebrovascular atherosclerosis. METHOD MIMIC-IV database was used to search for clinical data of patients with ischemic stroke. Included patients were divided into two groups according to their etiologies. Univariate and multivariate logistic regressions were used to build the predictive model, and the model reliability parameters were calculated. The cut-off value for the model was selected according to the Youden index. Clinical data from the Neurovascular Center of Changhai Hospital were used to verify the predictive model. RESULTS Logistical regressions showed a positive correlation between advanced age, peripheral atherosclerosis, history of transient ischemia, and the diagnosis of ischemic strokes due to cerebrovascular atherosclerosis. The history of atrial fibrillation, levels of the National Institutes of Health Stroke Scale, serum potassium, and activated partial thromboplastin time were negatively correlated to the diagnosis of cerebrovascular atherosclerotic ischemic stroke. The predictive model was constructed from logistic regression results, and the area under the curve was 0.764. The cut-off value for the model was set at 0.089 to achieve the highest Youden index, with sensitivity and specificity of 75.9% and 64.1%. Clinical verification of the model revealed that the sensitivity and specificity of the model were 52.5% and 93.0% respectively. CONCLUSION The efficacy of the predictive model was acceptable as an aid in predicting cerebrovascular atherosclerotic ischemic stroke.

Abstract
Lp-PLA2 is an enzyme encoded by the PLA2G7 gene located at chromosome 6p12-21, which is included in different signal transduction pathways. The potential of serum levels of Lp-PLA2 as a marker of inflammation quantifying cardio-metabolic risk, renal impairment and oxidative stress has been explored in earlier studies. It has also been used in chronic obstructive pulmonary disease, hepatic disease, metabolic conditions and exercise tolerance. Additionally, it shows promising evidence for the assessment of risk for certain cardiovascular conditions in otherwise seemingly healthy individuals. COVID-19 has affected life and the economy globally. The identification of biomarkers to assess the sickness and treatment plan is the need of the hour. This review summarizes the pathophysiological inter-relationship between serum levels of Lp-PLA2 and COVID-19. The authors hypothesize that the estimation of Lp-PLA2 levels may help in the early identification of risk and thus may play a beneficial role in the proactive management of COVID-19.

Abstract
We investigated the effects of dietary supplementation with Lactobacillus acidophilus and Bacillus subtilis on the intestinal immune response, intestinal barrier function, cecal microbiota profile, and metabolite profile in late-phase laying hens. Hens were divided into three groups and fed with the basal diet (NC group), basal diet supplementation with 250 mg/kg B. subtilis and L. acidophilus mixture powder (LD group), and basal diet supplementation with 500 mg/kg B. subtilis and L. acidophilus mixture powder (HD group), respectively. The results indicated that the dietary supplementation with L. acidophilus and B. subtilis increased the integrity of the intestinal barrier as evidenced by the significant increase in the number of ileal goblet cells and improve the expression of occludin, claudin-1, and ZO-1 genes in the HD group. Moreover, the levels of IL-6, TNF-α, and IFN-γ were significantly decreased in the LD and HD groups. The levels of immunoglobulin G (IgG) increased in the LD and HD group, and the levels of secretory immunoglobulin A (sIgA) increased with the HD treatment. Furthermore, 16 s rRNA sequencing revealed L. acidophilus in combination with B. subtilis increased the diversity of gut microbiota. The metabolomic analysis revealed beneficial changes in the amino acid metabolism and lipid metabolism (decrease in LysoPC and LysoPE levels). In conclusion, dietary supplementation with L. acidophilus and B. subtilis could improve intestinal barrier function and maintain immune homeostasis. These beneficial effects may be associated with the modulation of the intestinal microbiome and metabolites.

Multi-stage metabolomics and genetic analyses identified metabolite biomarkers of metabolic syndrome and their genetic determinants. EBioMedicine 2021; 74:103707. [PMID: 34801968 PMCID: PMC8605407 DOI: 10.1016/j.ebiom.2021.103707] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 10/07/2021] [Accepted: 11/05/2021] [Indexed: 12/18/2022] Open
Abstract
Background Metabolic syndrome (MetS) is a cluster of multiple cardiometabolic risk factors that increase the risk of type 2 diabetes and cardiovascular diseases. Identifying novel biomarkers of MetS and their genetic associations could provide insights into the mechanisms of cardiometabolic diseases. Methods Potential MetS-associated metabolites were screened and internally validated by untargeted metabolomics analyses among 693 patients with MetS and 705 controls. External validation was conducted using two well-established targeted metabolomic methods among 149 patients with MetS and 253 controls. The genetic associations of metabolites were determined by linear regression using our previous genome-wide SNP data. Causal relationships were assessed using a one-sample Mendelian Randomization (MR) approach. Findings Nine metabolites were ultimately found to be associated with MetS or its components. Five metabolites, including LysoPC(14:0), LysoPC(15:0), propionyl carnitine, phenylalanine, and docosapentaenoic acid (DPA) were selected to construct a metabolite risk score (MRS), which was found to have a dose-response relationship with MetS and metabolic abnormalities. Moreover, MRS displayed a good ability to differentiate MetS and metabolic abnormalities. Three SNPs (rs11635491, rs7067822, and rs1952458) were associated with LysoPC(15:0). Two SNPs, rs1952458 and rs11635491 were found to be marginally correlated with several MetS components. MR analyses showed that a higher LysoPC(15:0) level was causally associated with the risk of overweight/obesity, dyslipidaemia, high uric acid, high insulin and high HOMA-IR. Interpretation We identified five metabolite biomarkers of MetS and three SNPs associated with LysoPC(15:0). MR analyses revealed that abnormal LysoPC metabolism may be causally linked the metabolic risk.

Lysophosphatidylcholine induces apoptosis and inflammatory damage in brain microvascular endothelial cells via GPR4-mediated NLRP3 inflammasome activation. Toxicol In Vitro 2021; 77:105227. [PMID: 34293432 DOI: 10.1016/j.tiv.2021.105227] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 06/25/2021] [Accepted: 07/15/2021] [Indexed: 01/14/2023]
Abstract
Lysophosphatidylcholine (LPC), as the main active component of oxidized low-density lipoproteins (ox-LDLs), has significant effects in cerebrovascular disease. However, the complex mechanism by which LPC functions in brain microvascular endothelial cells (BMECs) is not clearly understood. In this study, BMECs were transfected with G protein-coupled receptor 4 (GPR4) siRNA or an NLRP3-overexpression plasmid, and GPR4 expression was identified by RT-qPCR and western blotting; IL-1β, IL-18, and IL-33 levels were evaluated by ELISA. Apoptosis was monitored by flow cytometry and Hoechst staining, while Caspase 3, ASC, NLRP3, and GPR4 protein expression were examined by western blotting. Our results showed that LPC significantly increased the levels of inflammatory cytokines (IL-1β, IL-18, and IL-33) and markedly induced apoptosis and NLRP3 inflammasome activation in BMECs. Moreover, LPC notably upregulated GPR4 in BMECs, and knockdown of GPR4 significantly attenuated the effects of LPC in BMECs. Above all, we also proved that LPC induced apoptosis and inflammatory injury in BMECs by causing GPR4 to activate NLRP3 inflammasomes. Therefore, GPR4-mediated activation of NLRP3 inflammasomes might be the underlying mechanism by which LPC promotes the progression of cerebrovascular disease. In summary we found that LPC is an important pathogenic factor in cerebrovascular disease, and can induce GPR4 to active NLRP3 inflammasomes.

[PMID: 33039628 DOI: 10.1016/j.jep.2020.113453] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 09/18/2020] [Accepted: 10/03/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Banxia Baizhu Tianma decoction (BBTD) is a classical representative prescription for expelling phlegm, extinguishing wind, strengthening the spleen and dissipating excessive fluid in traditional Chinese medicine (TCM). According to both TCM theory and about 300 years of clinical practice, BBTD is especially suitable for hypertensive patients of abdominal obesity and lacking physical activity. AIM OF THE STUDY The present study tried to interpret the pharmacology of the ancient formula of BBTD. Herein, we focused on the plasma metabonomics of BBTD and evaluated the effect and targets of BBTD on endothelial protective effect. METHODS Obesity-related hypertensive mice were induced by high-fat diet for 20 weeks. BBTD (17.8 g/kg) was administered intragastrically for 8 weeks, and telmisartan group (12.5 mg/kg) was used as positive drug. Body weight, blood pressure, triglyceride and cholesterol were recorded to evaluate the efficacy of BBTD in vivo. Lipid deposition in aortic roots was assessed by oil red O staining, while morphology of aortas was observed by HE staining. Ultra performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) was performed to study the plasma non-targeted metabonomics. According to the data of metabonomics, human aortic endothelial cells (HAECs) were treated by oxidized low-density lipoprotein (ox-LDL, 50 μg/mL) with/without BBTD (2, 1 or 0.5 mg/mL). Apoptosis rate (Annexin V-FITC/PI), migration (Transwell), cytoskeleton (Phalloidin) and density of VE-cadherin (Immunofluorescence staining) were used to investigate the effect of BBTD in vitro. Transcriptome sequencing was performed (2 mg/mL BBTD vs ox-LDL) to screen the possible targets of BBTD in endothelial protection against ox-LDL. RESULTS BBTD effectively reduced the body weight and total cholesterol, and decreased 12.1 mmHg in SBP and 10.5 mmHg in DBP of obesity-related hypertensive mice (P < 0.05). BBTD attenuated lipid deposition in arterial roots and improved the morphology of aortas in vivo. Plasma metabolite profiles identified 94 differential metabolites and suggested BBTD mainly affected glycerophospholipids and fatty acyls. Bioinformatics analysis indicated sphingolipid metabolism and fluid shear stress and atherosclerosis were main pathways. Therefore, we focused on endothelial protective effect of BBTD against ox-LDL. In vitro, BBTD demonstrated endothelial protective effects, decreasing apoptosis rate, improving cell migration in dose-dependent manner and maintaining cell morphology. Transcriptome sequencing identified 251 downregulated and 603 upregulated mRNAs after 24h-BBTD treatment, which reversed 51.8% change in mRNAs (393 DE mRNAs) induced by ox-LDL. Bioinformatics analysis supported the potential of BBTD in hypertension and suggested that BBTD improved endothelial cells by targeting mainly on p53 and PPAR signaling pathways. CONCLUSIONS BBTD attenuates obesity-related hypertension by regulating metabolism of glycerophospholipids and endothelial protection.
