Abstract
NaAsO2 is known as a harmful pollutant all over the world, and many chronic heart diseases can be attributed to its prolonged exposure in NaAsO2-contaminated water. Therefore, considering the anti-inflammatory and antioxidant effects of betaine (BET), in this study, our team investigated the cardioprotective effects of this phytochemical agent on sodium arsenite (NaAsO2)-induced cardiotoxicity. Forty male mice were randomly divided into 4 groups: (I) Control; (II) BET (500 mg/kg); (III) NaAsO2 (50 ppm); and (IV) NaAsO2 + BET. NaAsO2 was given to the animals for 8 weeks, but BET was given in the last two weeks. After decapitation, inflammatory factors and biochemical parameters were measured, and Western blot analyses were performed. BET decrease the activity level of alanine aspartate aminotransferase, creatine kinase MB, thiobarbituric acid reactive substances level, inflammatory factors (tumor necrosis factor-α) content, and nuclear factor kappa B expression. Furthermore, BET increased cardiac total thiol and activity levels of catalase, superoxide dismutase, and glutathione peroxidase and nuclear factor erythroid-2 expression. Hence, the administration of BET ameliorated the deleterious effects stemming from the imbalance of oxidative and antioxidant pathways and histopathological alterations observed in NaAsO2-intoxicated mice, thereby attenuating oxidative stress-induced damage and inflammation.

Additive effect between homocysteine and low-density-lipoprotein cholesterol upon incidence of novel carotid plaque formation: data from a Chinese community-based cohort. BMC Cardiovasc Disord 2023; 23:332. [PMID: 37386358 PMCID: PMC10311758 DOI: 10.1186/s12872-023-03282-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 05/07/2023] [Indexed: 07/01/2023] Open
Abstract
OBJECTIVE Homocysteine (HCY) has been associated with carotid plaque in cross-sectional studies, but the prospective relationship between HCY and incident carotid plaque has not been well established. The purpose of this study was to investigate the association between HCY and incidence of novel carotid plaque in a Chinese community-based population without pre-existing carotid atherosclerosis and to assess the additive effect of HCY and low-density lipoprotein cholesterol (LDL-C) on the incidence of novel plaque. METHODS At baseline, we measured HCY and other risk factors in subjects aged ≥ 40 years. All participants underwent carotid ultrasound examinations at baseline and after an average of 6.8 years of follow-up. Incidence of plaque was identified if plaque was absent at baseline, but plaque was detected at the end of follow-up. A total of 474 subjects were included in the analysis. RESULTS The incidence of novel carotid plaque was 24.47%. Multivariate regression analyses showed that HCY was independently associated with a 1.05-fold-higher likelihood for incident novel plaque (adjusted odds ratio [OR] = 1.05, 95% confidence interval [CI]: 1.01-1.09, P = 0.008). Using tertile 1 and tertile 2 for reference, the top HCY tertile (T3) showed a 2.28-fold-higher likelihood for incident plaque (adjusted OR = 2.28, 95%CI: 1.33-3.93, P = 0.002). The combination of HCY T3 and LDL-C ≥ 3.4 mmol/L had the highest risk for novel plaque formation (adjusted OR = 3.63, 95%CI: 1.67-7.85, P = 0.001) compared to those without either condition. In the LDL-C ≥ 3.4 mmol/L subgroup, HCY was significantly associated with incidence of plaque (adjusted OR = 1.16, 95%CI: 1.04-1.28, P = 0.005, P-interaction = 0.023). CONCLUSION In the Chinese community-based population, HCY was independently associated with the incidence of novel carotid plaque. There were additive effect between HCY and LDL-C on the incidence of plaque, the highest risk was observed in individuals with both high HCY levels and LDL-C ≥ 3.4 mmol/L. Our findings suggest that HCY may be a potential target for preventing the incidence of carotid plaque, particularly in individuals with elevated LDL-C levels.

Abstract
Information on the association between homocysteine (HCY) levels and carotid atherosclerosis (CAS) in hypertension (HTN) is limited. A cross-sectional study was performed to examine the relationship of plasma HCY concentration with CAS in 1700 hypertensives (61.62 ± 12.16 year). The prevalence of CAS and carotid intima-media thickness (CIMT) progressively increased across quartiles of HCY levels (P < 0.001). Correlation analysis showed significantly positive correlation between HCY and CAS (r = 0.261, P < 0.001). In a logistic regression, HCY independently predicted the presence of CAS (OR 1.284, 95% CI 1.163-1.418). Further investigation revealed that interaction effect of HCY was substantial for gender (P for interaction 0.023), age (P for interaction <0.001) and smoking (P for interaction 0.025) on CAS. Thus, in hypertensives, those of male, aged ≥55 year and current smokers, in which HCY ≥ 13.49 μmol/L were more likely to suffer CAS, suggesting a role of HCY in the development and progression of CAS in these patients, and HCY determination should be recommended to better stratify the cardiovascular risk.

Abstract
Previous studies have shown that plasma lipoprotein(a) (Lp(a)) plays an important role in the development of hypertensive organ damage. The aim of the present study was to investigate the relationship of Lp(a) with markers of arterial stiffening in hypertension. In 138 essential hypertensive patients free of diabetes, renal failure and cardiovascular complications, we measured plasma lipids and assessed vascular stiffness through the use of pulse wave analysis and calculation of the brachial augmentation index (AIx), and measured the pulse wave velocity (PWV). Plasma Lp(a) levels were significantly and directly related to both AIx (r = 0.490; p < 0.001) and PWV (r = 0.212; p = 0.013). Multiple regression analysis showed that AIx was independently correlated with age, C-reactive protein, and plasma Lp(a) (beta 0.326; p < 0.001), while PWV was independently and directly correlated with age, and inversely with HDL, but not with plasma Lp(a). Logistic regression indicated that plasma Lp(a) could predict an AIx value above the median for the distribution (p = 0.026). Thus, in a highly selective group of patients with hypertension, plasma Lp(a) levels were significantly and directly related to markers of vascular stiffening. Because of the relevance of vascular stiffening to cardiovascular risk, the reduction of Lp(a) levels might be beneficial for cardiovascular protection in patients with hypertension.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cardiovascular and cerebrovascular diseases have become a severe threat for human health worldwide, however, optimal therapeutic options are still developed. Zhilong Huoxue Tongyu capsule (ZL capsule) is mainly composed of Astragalus membranaceus, Leech, Earthworm, Cinnamomum cassia and Sargentodoxa cuneata, having functions of replenishing qi and activating blood, dispelling wind and reducing phlegm. It is an expanded application on the basis of traditional uses of above TCMs, acquiring a satisfactory curative effect on cardiovascular and cerebrovascular diseases over twenty years. AIM OF THE STUDY To comprehensively summarize the main components of ZL capsule, understand the mechanisms of ZL capsule, and conclude clinical regimens of ZL capsule for cardiovascular and cerebrovascular diseases. MATERIALS AND METHODS We selected network pharmacology technology to analyze main active compounds and predict underlying mechanism of ZL capsule against atherosclerosis. Molecular docking was performed to simulate the interaction pattern between the active components of ZL capsule and putative targets. Further, PubMed, Web of Science, China National Knowledge Infrastructure and Google Scholar were used to search literatures, with the key words of "Zhilong Huoxue Tongyu capsule", "cardiovascular and cerebrovascular diseases", "atherosclerosis", "clinical study" and their combinations, mainly from 2000 to 2020. RESULTS Both network pharmacology analysis, molecular docking and animal experiments studies confirmed that mechanisms of ZL capsule plays the role of anti-inflammatory, anti-apoptosis and promoting angiogenesis in treating cardiovascular and cerebrovascular diseases by multi-components acting on multi-targets via multi-pathways. Over 1000 clinical cases were benefited from the treatment of ZL capsule, suggesting a holistic concept of "the same therapy for different myocardial and cerebral diseases". CONCLUSIONS For the first time, this systematic review may supply meaningful information for further studies to explore material basis and pharmacodynamics of ZL capsule and also provide a basis for sharing the "Chinese patent medicine" for cardiovascular and cerebrovascular diseases.

Abstract
The influence of hyperhomocysteinemia (HHCy) on cardiovascular disease (CVD) remains unclear. HHCy is associated with inflammation and atherosclerosis, and it is an independent risk factor for CVD, stroke and myocardial infarction. However, homocysteine (HCy)-lowering therapy does not affect the inflammatory state of CVD patients, and it has little influence on cardiovascular risk. The HCy degradation product hydrogen sulfide (H2S) is a cardioprotector. Previous research proposed a positive role of H2S in the cardiovascular system, and we discuss some recent data suggesting that HHCy worsens CVD by increasing the production of H2S, which decreases the expression of adenosine A2A receptors on the surface of immune and cardiovascular cells to cause inflammation and ischemia, respectively.

Nutr Metab Cardiovasc Dis 2020; 30:1492-1499.

Abstract
BACKGROUND AND AIMS This study aimed to examine whether intraplaque neovascularization (IPN) of carotid plaques, as characterized by contrast-enhanced ultrasound (CEUS), is associated with atherosclerotic renal artery stenosis (ARAS) in patients with normal kidney function. METHODS AND RESULTS We investigated carotid IPN using CEUS in 198 consecutive patients with normal kidney function with and without ARAS. IPN was graded on the basis of the presence and location of microbubbles within each plaque (0, no visible microbubbles in the plaque; 1, moderate microbubbles confined to the shoulder and/or adventitial side of the plaque; and 2, extensive microbubbles throughout the plaque). The grades of each plaque were averaged to obtain an overall score per patient. ARAS was determined angiographically. We found that a higher CEUS-assessed carotid IPN score was associated with ARAS (Odd Ratio, OR: 7.281; 95% Confidence Interval, 95% CI: 3.246-16.336; P < 0.001). Furthermore, an IPN score >1.75 predicted severe stenosis with a sensitivity of 81% and specificity of 58%. Compared with using the IPN score alone, the addition of the homocysteine (HCY) cutoff value (>22.5 mmol/L) resulted in a stronger predictive value (Area Under Curve, AUC: 0.893 vs 0.834; P < 0.001) for severe ARAS. CONCLUSION Carotid plaque neovascularization combined with HCY levels is predictive of severe ARAS in patients with normal kidney function. CEUS-assessed carotid IPN is clinically useful for stratification of ARAS in patients with normal kidney function.

Abstract
The influences of hyperhomocysteinemia on cardiovascular diseases (CVDs), stroke and new-onset hypertension are unclear. The aim of the study is to explore the associations of homocysteine levels with stroke, CVDs, and new-onset hypertension in Chinese individuals.This retrospective cohort study included outpatients and inpatients from the Department of Geriatrics at Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine from January to December 2000. They were divided based on their homocysteine (Hcy) levels in 2000: Q1 (<10 μmol/L), Q2 (10-15 μmol/L), and Q3 (>15 μmol/L) and according to whether they had hypertension at baseline. Information about stroke, mortality and major adverse cardiac events, and newly onset hypertension was gathered in December each year until 2017. The effects of Hcy levels on the risk for stroke and CVDs among all patients, and new-onset hypertension among patients without hypertension at baseline were evaluated.After adjustment for confounders, compared with the Q1 group (Hcy <10 μmol/L), when the Hcy increased to 10 to 15 μmol/L, the risks for stroke, CVDs, and new-onset hypertension significantly increased, and the hazard ratio and 95% confidence interval were 2.02 (1.35-3.05, P = .001), 2.22 (1.32-3.76, P = .003), and 7.20 (4.52-11.48, P < .001), respectively. Hcy improved the predictive capability of traditional risk factors for stroke. The optimal cut-off value of Hcy for predicting stroke was 13.4 μmol/L (sensitivity: 70.9%, specificity: 62.2%).Hcy 10 to 15 μmol/L is significantly associated with the risks for stroke, mortality and major adverse cardiac events, and hypertension. The best cut-off point of Hcy for predicting stroke is 13.4 μmol/L.

Abstract
BACKGROUND Ischemic stroke is related to the level of total homocysteine and the stability of carotid atherosclerotic plaque. In this study, the characteristics of carotid plaque in hypertensive patients with hyperhomocysteinemia were preliminarily studied by conventional ultrasound, contrast-enhanced ultrasound and virtual touch image quantification. METHODS Hypertensive patients (n=196) hospitalised in the Department of Neurology and Cardiology of our hospital from April 2016 to February 2019 were studied to compare and analyse differences in general clinical data, conventional ultrasound, contrast-enhanced ultrasound and virtual touch image quantification between hypertension with hyperhomocysteinemia and hypertension with normal tHcy. RESULTS 1. There was no statistical difference in other clinical data, except fasting blood sugar (P=0.021) and the history of cerebral infarction (P=0.0001). 2. There were significant differences in plaque thickness, stenosis degree, contrast-enhanced ultrasound level, The maximum shear wave velocity (SWVmax) , the minimum shear wave velocity (SWVmin) and the mean shear wave velocity (SWVmean) (P<0.05), except intima-media thickness between the two groups (t=0.160, P=0.873). 3. Blood tHcy level in hypertensive patients with hyperhomocysteinemia was positively correlated with carotid plaque thickness, stenosis degree and contrast-enhanced ultrasound level (r=0.349, 0.647, 0.421), but negatively correlated with SWVmax, SWVmin and SWVmean (r=-0.348, -0.409, -0.393). CONCLUSIONS Ultrasonography can reflect the vulnerability of hypertensive patients with hyperhomocysteinemia, providing reliable and comprehensive information for the prevention and treatment of stroke in hypertensive patients with hyperhomocysteinemia.

Astaxanthin inhibits homocysteine‑induced endothelial cell dysfunction via the regulation of the reactive oxygen species‑dependent VEGF‑VEGFR2‑FAK signaling pathway. Mol Med Rep 2019; 19:4753-4760. [PMID: 31059085 PMCID: PMC6522805 DOI: 10.3892/mmr.2019.10162] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Accepted: 04/10/2019] [Indexed: 12/11/2022] Open
Abstract
Increased plasma levels of homocysteine (Hcy) can cause severe damage to vascular endothelial cells. Hcy‑induced endothelial cell dysfunction contributes to the occurrence and development of human cerebrovascular diseases (CVDs). Our previous studies have revealed that astaxanthin (ATX) exhibits novel cardioprotective activity against Hcy‑induced cardiotoxicity in vitro and in vivo. However, the protective effect and mechanism of ATX against Hcy‑induced endothelial cell dysfunction requires further investigation. In the present study, treatment of human umbilical vascular endothelial cells (HUVECs) with Hcy inhibited the migration, invasive and tube formation potentials of these cells in a dose‑dependent manner. Hcy treatment further induced a time‑dependent increase in the production of reactive oxygen species (ROS), and downregulated the expression of vascular endothelial growth factor (VEGF), phosphorylated (p)‑Tyr‑VEGF receptor 2 (VEGFR2) and p‑Tyr397‑focal adhesion kinase (FAK). On the contrary, ATX pre‑treatment significantly inhibited Hcy‑induced cytotoxicity and increased HUVEC migration, invasion and tube formation following Hcy treatment. The mechanism of action may involve the effective inhibition of Hcy‑induced ROS generation and the recovery of FAK phosphorylation. Collectively, our findings suggested that ATX could inhibit Hcy‑induced endothelial dysfunction by suppressing Hcy‑induced activation of the VEGF‑VEGFR2‑FAK signaling axis, which indicates the novel therapeutic potential of ATX in treating Hcy‑mediated CVD.

Abstract
BACKGROUND Elevated plasma homocysteine (Hcy) concentration is considered as the diagnostic criteria of Hyperhomocysteinemia (HHcy), which is associated with the inflammatory response and blood-brain barrier disruption. Previous studies have proposed that HHcy with hypertension was associated with the brain injury by enhancing the cerebrovascular permeability, however, the immune mechanism remains obscure. The purpose of the study is to explore the immunomodulatory mechanism of brain injury in spontaneously hypertensive rats (SHRs) induced by HHcy. MATERIALS AND METHODS Sixty SHRs were randomly assigned to three groups: SHR-C (control group), SHR-M (methionine group) and SHR-T (treatment group). Physical examination of body weight, systolic blood pressure (SBP) and plasma Hcy content was measured every 4 weeks. Besides, T-helper cell 17 and regulatory T cells (Treg)-related inflammatory cytokines (interleukin [IL]-6, IL-17, IL-10, and transforming growth factor beta [TGF-β]) and genes (RORγt and FoxP3) were detected by enzyme-linked immunosorbent assay, quantitative polymerase chain reaction , Western blot, and immunohistochemistry. RESULTS High methionine diet could cause weight loss, SBP rising, and plasma Hcy content significantly elevated. IL-16 and IL-17A levels in peripheral blood and in brain tissue both lifted, while IL-10 and TGF-β levels dropped; RORγt expression raised in brain, nevertheless, FoxP3 levels were the opposite. After the intervention with vitamin B6, B12, and folic acid in SHR-T group, these trends would be eased or completely changed. Furthermore, brain tissue slices showed that IL-17-positive cells tended to decrease, and IL-10-positive cells increased in SHR-T group, which was reversed in SHR-M group. CONCLUSIONS HHcy may promote inflammation that can lead to brain lesions and down-regulate immune response to protect the brain.

Abstract
Recent investigations have revealed that changes in DNA methylation status play an important role in aging-associated pathologies and lifespan. The methylation of DNA is regulated by DNA methyltransferases (DNMT1, DNMT3a, and DNMT3b) in the presence of S-adenosylmethionine (SAM), which serves as a methyl group donor. Increased availability of SAM enhances DNMT activity, while its metabolites, S-adenosyl-l-homocysteine (SAH) and decarboxylated S-adenosylmethionine (dcSAM), act to inhibit DNMT activity. SAH, which is converted from SAM by adding a methyl group to cytosine residues in DNA, is an intermediate precursor of homocysteine. dcSAM, converted from SAM by the enzymatic activity of adenosylmethionine decarboxylase, provides an aminopropyl group to synthesize the polyamines spermine and spermidine. Increased homocysteine levels are a significant risk factor for the development of a wide range of conditions, including cardiovascular diseases. However, successful homocysteine-lowering treatment by vitamins (B6, B12, and folate) failed to improve these conditions. Long-term increased polyamine intake elevated blood spermine levels and inhibited aging-associated pathologies in mice and humans. Spermine reversed changes (increased dcSAM, decreased DNMT activity, aberrant DNA methylation, and proinflammatory status) induced by the inhibition of ornithine decarboxylase. The relation between polyamine metabolism, one-carbon metabolism, DNA methylation, and the biological mechanism of spermine-induced lifespan extension is discussed.

Abstract
Background Border zone infarcts (BZI) are ischemic lesions at the junction between two main arterial territories which may be either cortical or internal BZI. Methods This study was conducted on 76 cerebral BZI patients and 20 healthy control subjects. Patients were divided to group I included 26 internal BZI, group II included 19 cortical BZI and group III included 21 mixed internal/cortical BZI patients. Included subjects were submitted to neurological examination, laboratory investigations, ECG, echocardiogram, brain CT and/or MRI and extra and intracranial blood vessels imaging by duplex and CT angiography. Results Hypertension was significantly higher among groups I and III compared to group II while atrial fibrillation (AF) was significantly higher in groups II and III than group I (p < 0.05). Sonographic duplex assessment of extra and intracranial blood vessels revealed significant increase in mean flow velocities of CCA, ICC and MCA on both side in groups I and III compared to group II (p < 0.05). CT angiography revealed non-significant differences between BZI patients and control as well as in between the three BZI patient's groups regarding the existence of vertebral artery hypoplasia and/or circle of Willis anomalies. Conclusions Vascular stenosis is the main etiological factor in internal BZI while AF is the predominant etiological factor of cortical BZI. Congenital vascular anomalies play roles in the localization of BZI but cannot predispose to it except when comorbid with hemodynamic disturbances.

Abstract
Objective Coronary artery disease is major cause of mortality and morbidity. Homocysteine has long been postulated as an underlying factor for atherosclerosis leading to coronary artery disease, yet its role in young patients is uncertain. This study was aimed to analyze the correlation between plasma homocysteine and coronary artery disease among young adults in the absence of conventional risk factors. Methods It was a case-control study carried out at Rehman Medical Institute, Peshawar, Pakistan from October 1, 2016, to September 30, 2017. Universal sampling technique was adopted and 158 participants were included. A total of 30 participants were in the control group and 128 were in the patient group, who had moderate to severe stenosis in either single or multiple major coronary arteries on coronary angiography and aged <40 years. Results Cases and controls had similar characteristics but differed significantly in serum homocysteine concentration. In the control group, the mean plasma homocysteine concentration of 6.3 (±2.05) μmol/L and in the patient group a mean plasma homocysteine concentration of 44.5 (±14.01) μmol/L was observed. All the patients with moderate to severe stenosis in single or major coronary arteries had raised plasma homocysteine concentrations. Among 128 patients, 15 (11.7%) had moderate increase, 109 (85.2%) had intermediate increase, and four (3.1%) had severe increase in plasma homocysteine levels. Single vessel coronary artery disease was observed in 118 (92.2%) patients, whereas 10 (7.8%) had more than one major coronary artery involvement. Conclusion Hyper-homocysteinemia has positive correlation with coronary artery disease among young adults in the absence of conventional risk factors.

Abstract
OBJECTIVES Comorbid hypertension and hyperhomocysteinemia is an important risk factor for carotid atherosclerotic plaque formation. We put forward the hypothesis that the subjects with comorbid prehypertension and hyperhomocysteinemia also had an increased risk of subclinical atherosclerosis, using carotid intima-media thickness (CIMT) as the marker of the atherosclerotic process. METHODS A total of 4102 asymptomatic Chinese subjects aged 18-60 years were divided into four groups according to blood pressure (BP) and homocysteine (HCY) level: the control group without prehypertension or hyperhomocysteinemia, isolated prehypertension group, simple hyperhomocysteinemia group and prehypertension with hyperhomocysteinemia group. Serum lipids, fasting blood glucose (FBG), HCY and CIMT were measured. RESULTS There was significant difference in the positive rates of increased CIMT among four groups. Compared with the controls, the subjects in the other three groups had a higher risk of increased CIMT (isolated prehypertension group, OR 2.049, 95% CI 1.525 to 2.754; simple hyperhomocysteinemia group, OR 2.145, 95% CI 1.472 to 3.125; prehypertension and hyperhomocysteinemia group, OR 3.199, 95% CI 2.362 to 4.332). However, by multiple logistic regression analysis, only comorbid prehypertension and hyperhomocysteinemia was independently associated with increased CIMT (OR 1.485, 95% CI 1.047 to 2.108, P<0.05). CONCLUSIONS Comorbid prehypertension and hyperhomocysteinemia was an independent risk factor of subclinical atherosclerosis in asymptomatic Chinese, but isolated prehypertension or hyperhomocysteinemia was not. Therefore, combined intervention for prehypertension and hyperhomocysteinemia may contribute to decrease the incident of cardiovascular disease.

Abstract
Elevated plasma homocysteine (Hcy) is suggested as an independent risk factor for stroke. We aimed to investigate the association of Hcy concentration with intracranial atherosclerosis (ICAS) and extracranial AS (ECAS) in hypertensive patients without stroke in Chinese population and to explore modified effect of methylenetetrahydrofolate reductase (MTHFR) C677T on their relationship. The stenosis of intracranial and extracranial arteries were evaluated in a total of 929 subjects through computerized tomographic angiography (CTA) from aortic arch to the skull base. Hcy concentration showed significantly association with both ICAS (OR: 1.105; 95% CI: 1.057-1.155) and ECAS (OR: 1.096; 95% CI: 1.047-1.146) for 1 µmol/L increment in Hcy. Meanwhile, hyperhomocysteinemia (≥15 µmol/L) was also displayed association with ICAS (OR: 1.587; 95% CI: 1.029-2.446) and ECAS (OR: 2.164; 95% CI: 1.392-3.364) after fully adjustment. Furthermore, in the subgroup analysis, such association remained significant only in the subjects that were younger, with normal renal function and with MTHFR 677 C allele. Our study showed the significant association of Hcy with ECAS and ICAS in asymptomatic hypertension patients. Hcy played a universal effect on the cervico-cerebral atherosclerosis. Such association was modified by the MTHFR C677T genotype.

Abstract
This study aimed to investigate whether conventional predisposing factors modify the associations of homocysteine with blood pressure levels and hypertension. A total of 2615 adults were recruited from Liaoning province. An elevated homocysteine level was significantly associated with increased hypertension risk and blood pressure (all P<.05). Interaction analyses showed that homocysteine acted synergistically with age, overweight/obesity, dyslipidemia, and family history of hypertension to affect hypertension risk, and the relative excess risk due to interaction was 1.21 (95% confidence interval, 0.07-2.35), 0.72 (95% confidence interval, 0.07-1.36), 0.45 (95% confidence interval, 0.06-0.85), and 1.87 (95% confidence interval, 0.77-2.97), respectively. Increases in blood pressure were higher in patients who were overweight/obese or had a family history of hypertension than in their counterparts (all Pinteraction <.05). This study provides some strong evidence for interactions of homocysteine with conventional predisposing factors on hypertension.

Abstract
Atherosclerosis is a chronic disease that can seriously endanger human life. Folic acid supplementation modulates several disorders, including atherosclerosis, via its antiapoptotic and antioxidative properties. This study investigated whether folic acid alleviates atherogenesis by restoring homocysteine levels and antioxidative capacity in atherosclerosis Wistar rats. To this end, 28 Wistar rats were randomly divided into 4 groups (7 rats/group) as follows: (i) wild-type group, fed only the AIN-93 semi-purified rodent diet (folic acid: 2.1 mg/kg); (ii) high-fat + folic acid-deficient group (HF+DEF) (folic acid: 0.2 mg/kg); (iii) high-fat + normal folic acid group (folic acid: 2.1 mg/kg); and (iv) high-fat + folic acid-supplemented group (folic acid: 4.2 mg/kg). After 12 weeks, histopathological changes in the atherosclerotic lesions of the aortic arch were determined. In addition, serum folate levels, plasma homocysteine levels, plasma S-adenosyl-homocysteine levels, antioxidant status, oxidant status, and lipid profiles were evaluated. The results show aggravated atherosclerotic lesions in the HF+DEF group. Folic acid supplementation increased concentrations of serum folate. Further, folic acid supplementation increased high-density lipoprotein-cholesterol, decreased plasma homocysteine levels, and improved antioxidant capacity in atherogenic rats. These findings are consistent with the hypothesis that folic acid alleviates atherogenesis by reducing plasma homocysteine levels and improving antioxidant capacity in rats fed a high-fat diet.

Abstract
Little is known about the association between homocysteine (Hcy) and asymptomatic CAS in the healthy population. The purpose of this study was to investigate the relationship between Hcy levels and asymptomatic CAS in a Chinese community population. The current study included 5393 participants who were age of 40 years or older, and free of stroke, transient ischemic attack, and coronary artery disease. Demographic and clinical variables were investigated, and the presence of CAS was assessed by Color Doppler Ultrasound. A multivariate logistic regression was used to examine the association between Hcy levels and asymptomatic CAS. 361 (6.69%) participants were diagnosed with asymptomatic CAS, who had higher Hcy levels compared with those without (p-value for trend = 0.0001). After adjusting other possible risk factors, Hcy > 19.3μmol/L was considered as an independent indicator of asymptomatic CAS (OR 1.53, 95%CI 1.05–2.23; p-value for trend = 0.0265), but with a difference between participants with diabetes and without [OR (95%CI): 2.89(1.02–8.22) vs. 1.42(0.95–2.12); P interaction < 0.05]. In this large-population, community-based study, Hcy is an independent indicator of asymptomatic CAS, especially in patients with diabetes.

High homocysteine levels prevent via H2 S the CoCl2 -induced alteration of lymphocyte viability. J Cell Mol Med 2016; 20:1411-9.

Abstract
High homocysteine (HCy) levels are associated with lymphocyte‐mediated inflammatory responses that are sometimes in turn related to hypoxia. Because adenosine is a potent lymphocyte suppressor produced in hypoxic conditions and shares metabolic pathways with HCy, we addressed the influence of high HCy levels on the hypoxia‐induced, adenosine‐mediated, alteration of lymphocyte viability. We treated mitogen‐stimulated human lymphocytes isolated from healthy individuals and the human lymphoma T‐cell line CEM with cobalt chloride (CoCl2)to reproduce hypoxia. We found that CoCl2‐altered cell viability was dose‐dependently reversed using HCy. In turn, the HCy effect was inhibited using DL‐propargylglycine, a specific inhibitor of the hydrogen sulphide (H2S)‐synthesizing enzyme cystathionine‐γ‐lyase involved in HCy catabolism. We then addressed the intracellular metabolic pathway of adenosine and HCy, and the role of the adenosine A2A receptor (A2AR). We observed that: (i) hypoxic conditions lowered the intracellular concentration of HCy by increasing adenosine production, which resulted in high A2AR expression and 3′, 5′‐cyclic adenosine monophosphate production; (ii) increasing intracellular HCy concentration reversed the hypoxia‐induced adenosinergic signalling despite high adenosine concentration by promoting both S‐adenosylhomocysteine and H2S production; (iii) DL‐propargylglycine that inhibits H2S production abolished the HCy effect. Together, these data suggest that high HCy levels prevent, via H2S production and the resulting down‐regulation of A2AR expression, the hypoxia‐induced adenosinergic alteration of lymphocyte viability. We point out the relevance of these mechanisms in the pathophysiology of cardiovascular diseases.

Abstract
The cardioprotective role of xuefu zhuyu decoction (XZD), a well-known classical herbal formula, has been documented for hypertension treatment recently. This study aims to summarize the efficacy and safety of XZD in treating hypertension.Seven databases were searched to identify randomized controlled trials evaluating the efficacy of XZD in hypertensive patients. Fifteen studies involving 1364 hypertensive patients were included. All studies compared XZD and antihypertensive drugs with antihypertensive drugs used alone.In all, 15 studies reported significant effects of XZD for lowering blood pressure compared with the control group (P < 0.05), and 7 studies reported significant effects of XZD for improving symptoms compared with the control group (P < 0.00001). Meanwhile, studies reported XZD was more efficacious than antihypertensive drugs in improving total cholesterol, triglycerides, low-density lipoprotein cholesterol, homocysteine, hemorheology, carotid intima-media thickness, and left ventricular mass index (P < 0.05). No severe adverse event was reported.This meta-analysis provides evidence that XZD is beneficial for hypertension. Although concerns regarding selective bias and methodologic flaws were raised, our findings suggests XZD as a new candidate cardioprotective drug for hypertension, which should be given priority for future preclinical and clinical studies.
