Abstract
OBJECTIVE To study the rate and characteristics of H-type hypertension in Chinese hypertensive population, and to compare them with the relevant data from the United States. METHODS Observational studies on the prevalence of H-type hypertension in Chinese population published before April 30, 2022 were searched in several Chinese and English databases (PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Databases, and Chinese Biome-dical Literature Database). Study selection, date extraction and quality evaluation were conducted. Random effect model was used to estimate the rate of H-type hypertension in hypertensive patients and the pooled prevalence of H-type hypertension. Stratified analysis was used to explore the distribution characteristics of H-type hypertension in China. We made meta-regression to search the source of heterogeneity. The National Health and Nutrition Examination Survey (NHANES) population from 1999 to 2006 in the United States was divided into four stages according to the time of data collection. Basic information of the participants was acquired from the database and the rate and prevalence of H-type hypertension analyzed. RESULTS This study was finally comprised of 33 studies, involving 78 470 patients with hypertension, among whom 59 842 patients were with H-type hypertension. The rate of H-type hypertension in hypertensive population in China was 73.1% (95%CI: 69.3%-76.9%, I2=99.4%, P < 0.001), and the prevalence of H-type hypertension in general population was 26.9% (95%CI: 21.1%-32.8%, I2=99.8%, P < 0.001). In the stratified analysis, the rate of H-type hypertension was higher among the elderly over 65 years, males, ethnic minorities, and residents in the inland, western, northern, and rural areas. During the decade from 2011 to 2020, the rate of H-type hypertension in China declined slowly (2011-2013: 79.2% vs. 2014-2016: 70.4% vs. 2017-2020: 66.6%, P < 0.001). Meta-regression showed that area was the source of heterogeneity. The rate of H-type hypertension in the United States increased over time, reaching a high value in 2003-2004 and then declining in 2005-2006. The rate of H-type hypertension in hypertensive patients and the prevalence of H-type hypertension in general population in the United States was lower than that in China. CONCLUSION Although the rate of H-type hypertension in Chinese hypertensive patients has a downtrend, it still far exceeds that in the United States, especially in the elderly, males, ethnic minorities, and residents in the inland, western, northern, and rural areas. Understanding the epidemiology of H-type hypertension provides scientific evidence for further prevention of cardiovascular and cerebrovascular diseases.

Serum Homocysteine Level Predictive Capability for Severity of Restenosis Post Percutaneous Coronary Intervention. Front Pharmacol 2022; 13:816059.

Abstract
Background: In stent restenosis (ISR) is one of the major complications after stent implantation. Thus, there is a growing interest in identifying a biomarker for the onset of ISR. High levels of serum homocysteine (Hcy) have been associated with the progression of cardiovascular disease. Therefore, the study was carried out to quantify the correlation between serum Hcy and ISR severity. Compared with coronary angiography (CAG), Hcy levels provided a significantly better clinical detection of ISR severity after PCI. Methods: A total of 155 patients were recruited from Shanxi Bethune hospital, from 6 months to 2 years post PCI. Serum Hcy levels and postoperative angiography results were used to differentiate the patients into two experimental groups: ISR (>50% diametrical stenosis), and non-ISR. The non-ISR included two subgroups: intimal hyperplasia (10–50% diametrical stenosis), and recovery (<10% diametrical stenosis). In addition, a group of 80 healthy individuals was used as a negative control. The correlation between homocysteine level and ISR severity t was analyzed for all groups. In addition, the correlation between serum Hcy level and the severity of ISR in the experimental group was analyzed by the Pearson correlation test. Results: The serum Hcy level in the experimental group and control group was determined to be (20.21 ± 11.42) μmol/L and (15.11 ± 10.25) μmol/L respectively. The level of serum Hcy in the experimental group was significantly higher than in the control group (t-value of 2.385; p-value of 0.019). The serum Hcy level in the restenosis and the intimal hyperplasia group was (25.72 ± 13.71) μmol/L and (17.35 ± 7.70) μmol/L respectively. The serum Hcy level in the restenosis group was significantly higher than in the intimal hyperplasia group (t-value of 2.215; p-value of 0.033). The level of serum Hcy in the group without a plaque in the stent was (16.30 ± 6.08) μmol/L, whereas in the control group was (15.11 ± 10.25) μmol/L. The no plaque group had a slightly higher serum Hcy level than the control group (t-value of 0.634; p-value of 0.528). All included patients were divided into four quartiles based on the serum Hcy concentration: quartile 1 (8.90–13.20 μmol/L), quartile 2 (13.30–16.45 μmol/L), quartile 3 (16.60–24.25 μmol/L) and quartile 4 (24.30-65.30 μ mol/L). The incidence of ISR was 5, 6.25, 7.5 and 15%, in the 1,2,3 and four quartiles respectively. The serum Hcy level in the experimental group was (20.21 ± 11.42) μmol/L, the severity of in-stent restenosis was (0.25 ± 0.31), (R-value was 0.234; p-value was 0.037), indicating a correlation between serum Hcy and the severity of restenosis (p < 0.05). Taking coronary angiography as the gold standard, a ROC curve analysis was performed on the serum Hcy levels for the experimental group. The area under the curve (AUC) was 0.718 (95% CI 0.585-0.854, p < 0.001), indicating that the serum Hcy concentration could predict ISR. On the ROC curve, the best critical value of serum Hcy concentration for predicting ISR was 20.05 μmol/L, with a sensitivity of 45% and specificity of 88.1%. Conclusion: A positive correlation was observed between homocysteine and the severity of restenosis after PCI, The level of Hcy could serve as a predictive biomarker for the severity of ISR.

Abstract
Simple Summary Hyperhomocysteinemia has been defined as an elevated serum concentration of homocysteine exceeding 15 μmol/L and has been proven to play an important role in the pathogenesis of cerebrovascular disease. The prevalence of hyperhomocysteinemia in China has been outlined in a previous meta-analysis. Considering the key role of homocysteine in the process of vascular injury, more studies have been conducted to prevent hyperhomocysteinemia by nutritional supplements such as folic acid or other treatments. Additionally, studies have shown that the prevalence of hyperhomocysteinemia increases over time; therefore, it was necessary to provide an update from the previous meta-analysis on homocysteine status in China. This was needed to understand the prevalence, the trend in changes over time, and its determinants. The results highlight that the prevalence of hyperhomocysteinemia is increasing in China, especially among the elderly, men, and residents in the north, inland areas, and rural areas of China. Abstract We conducted a meta-analysis to systematically assess the prevalence of hyperhomocysteinemia (HHcy) in China, its change over time, and its determinants. Literature searches were conducted using English databases (PubMed, Embase, and Web of Science) and Chinese databases (CNKI, CBM, VIP, and Wanfang). The time ranges were from Jan 2014 to Mar 2021 in China. We adopted the random effects model to estimate the pooled positive rates of HHcy and corresponding 95% confidence intervals (95% CI). To find the sources of heterogeneity, we performed subgroup analysis and meta-regression. A total of 29 related articles were identified involving 338,660 participants with 128,147 HHcy cases. The estimated prevalence of HHcy in China was 37.2% (95% CI: 32.6–41.8%, I2 = 99.8%, p for heterogeneity < 0.001). The trend of HHcy prevalence was gradually upward over time, with increases during 2015–2016 (comparison to 2013–2014, p < 0.001), but steady between 2015–2016 and 2017–2018. Subgroup analysis showed that the prevalence was higher in the elderly over 55 years old, males, and residents in the north, inland, and rural China (for each comparison, p < 0.001). Meta-regression analysis revealed that age and area of study contributed to 42.3% of the heterogeneity between studies. The current meta-analysis provides strong evidence that the prevalence of HHcy is increasing in China, and varies substantially across different ages, genders, and geographic distribution. Accordingly, high-risk population groups should be focused on, and public health policies and strategies should be carried out to prevent and control HHcy in China.

Abstract
Homocysteine, an amino acid containing a sulfhydryl group, is an intermediate product during metabolism of the amino acids methionine and cysteine. Hyperhomocysteinemia is used as a predictive risk factor for cardiovascular disorders, the stroke progression, screening for inborn errors of methionine metabolism, and as a supplementary test for vitamin B12 deficiency. Two organic systems in which homocysteine has the most harmful effects are the cardiovascular and nervous system. The adverse effects of homocysteine are achieved by the action of several different mechanisms, such as overactivation of N-methyl-d-aspartate receptors, activation of Toll-like receptor 4, disturbance in Ca2+ handling, increased activity of nicotinamide adenine dinucleotide phosphate-oxidase and subsequent increase of production of reactive oxygen species, increased activity of nitric oxide synthase and nitric oxide synthase uncoupling and consequent impairment in nitric oxide and reactive oxygen species synthesis. Increased production of reactive species during hyperhomocysteinemia is related with increased expression of several proinflammatory cytokines, including IL-1β, IL-6, TNF-α, MCP-1, and intracellular adhesion molecule-1. All these mechanisms contribute to the emergence of diseases like atherosclerosis and related complications such as myocardial infarction, stroke, aortic aneurysm, as well as Alzheimer disease and epilepsy. This review provides evidence that supports the causal role for hyperhomocysteinemia in the development of cardiovascular disease and nervous system disorders.

Abstract
OBJECTIVE An index of biomarkers derived from dietary factors (diet-biomarker-related index) identifies foods and nutrients that encompass physiological potentials and provides scientific evidence for dietary patterns that increase the risk of disease associated with specific biomarkers. Although men and women have different dietary patterns and physiological characteristics, sex is not often considered when investigators develop a diet-biomarker-related index. We aimed to review whether epidemiological studies developed diet-biomarker-related indices in a sex-specific way. DESIGN We systematically searched for epidemiological studies that developed diet-biomarker-related indices, including (i) biomarker prediction indices that include dietary factors as explanatory variables and (ii) dietary patterns to explain biomarker variations, in the PubMed and EMBASE databases. We qualitatively reviewed the sex consideration in index development. RESULTS We identified seventy-nine studies that developed a diet-biomarker-related index. We found that fifty-four studies included both men and women. Of these fifty-four studies, twenty-nine (53·7 %) did not consider sex, eleven (20·3 %) included sex in the development model, seven (13·0 %) considered sex but did not include sex in the development model, and seven (13·0 %) derived a diet-biomarker-related index for men and women separately. A list of selected dietary factors that explained levels of biomarkers generally differed by sex in the studies that developed a diet-biomarker-related index in a sex-specific way. CONCLUSIONS Most studies that included both men and women did not develop the diet-biomarker-related index in a sex-specific way. Further research is needed to identify whether a sex-specific diet-biomarker-related index is more predictive of the disease of interest than an index without sex consideration.

Abstract
BACKGROUND This study aimed to investigate the status of internal quality control (IQC) for cardiac biomarkers from 2011 to 2016 so that we can have overall knowledge of the precision level of measurements in China and set appropriate precision specifications. METHODS Internal quality control data of cardiac biomarkers, including creatinine kinase MB (CK-MB) (μg/L), CK-MB(U/L), myoglobin (Mb), cardiac troponin I (cTnI), cardiac troponin T (cTnT), and homocysteines (HCY), were collected by a web-based external quality assessment (EQA) system. Percentages of laboratories meeting five precision quality specifications for current coefficient of variations (CVs) were calculated. Then, appropriate precision specifications were chosen for these six analytes. Finally, the CVs and IQC practice were further analyzed with different grouping methods. RESULTS The current CVs remained nearly constant for 6 years. cTnT had the highest pass rates every year against five specifications, whereas HCY had the lowest pass rates. Overall, most analytes had a satisfactory performance (pass rates >80%), except for HCY, if one-third TEa or the minimum specification were employed. When the optimal specification was applied, the performance of most analytes was frustrating (pass rates < 60%) except for cTnT. The appropriate precision specifications of Mb, cTnI, cTnT and HCY were set as current CVs less than 9.20%, 9.90%, 7.50%, 10.54%, 7.63%, and 6.67%, respectively. The data of IQC practices indicated wide variation and substantial progress. CONCLUSION The precision performance of cTnT was already satisfying, while the other five analytes, especially HCY, were still frustrating; thus, ongoing investigation and continuous improvement for IQC are still needed.

Int J Cancer 2017; 139:996-1008.

Abstract
Vitamin B2 serves as a cofactor to enhance one-carbon metabolism, maintain mucous membranes, and has been implicated in lowering colorectal cancer (CRC) risk. However, few prospective studies have examined the association between vitamin B2 intake and CRC. In this study, we estimated the associations between vitamin B2 intake and CRC risk using the Nurses' Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS) cohorts. Vitamin B2 intake was measured by a validated food frequency questionnaire every 4 years. Among 100,033 women in the NHS and 44,007 men in the HPFS we documented a total of 3,037 incident CRC cases (2,093 women and 944 men) during 24-26 years of follow-up until 2010. Intakes of total (from food and supplements), dietary (from food only), and supplemental vitamin B2 were inversely related to CRC risk in age-adjusted analysis in NHS. However, the association was attenuated and no longer statistically significant in multivariate analysis (p-trend ≥0.08). The pooled multivariate relative risks (95% confidence interval) comparing individuals in the extreme quintiles of intakes were 0.93 (0.81-1.06) for total vitamin B2, 0.89 (0.61-1.28) for dietary vitamin B2 and 0.94 (0.81-1.08) for supplemental vitamin B2. These associations of total vitamin B2 intake were similar for risk of CRC with varying lag-time periods (0-4, 4-8, 8-12 or 12-16 years), for risk of CRC subtypes by tumor location, and across strata of intake of folate or alcohol. Our prospective data do not support a beneficial role of vitamin B2 intake in lowering incidence of CRC.

Am J Clin Nutr 2016; 104:173-80. [PMID: 27281307 PMCID: PMC4919531 DOI: 10.3945/ajcn.116.131771] [Citation(s) in RCA: 61] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2016] [Accepted: 05/11/2016] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The trimethylamine-containing nutrient phosphatidylcholine is the major dietary source for the gut microbiota metabolite trimethylamine-N-oxide (TMAO), which has been related to cardiovascular diseases (CVDs) and mortality. Previous research suggested that the relation of TMAO with CVD risk might be stronger in diabetic than in nondiabetic populations. However, the evidence for an association of dietary phosphatidylcholine with CVD and mortality is limited. OBJECTIVES We aimed to examine whether dietary consumption of phosphatidylcholine, which is mainly derived from eggs, red meat, and fish, is related to all-cause and CVD mortality in 2 cohorts of US women and men. In particular, we also tested if such an association was modified by diabetes status. DESIGN We followed 80,978 women from the Nurses' Health Study (1980-2012) and 39,434 men from the Health Professionals Follow-Up Study (1986-2012), who were free of cancer and CVD at baseline, for mortality. Dietary intakes and potential confounders were assessed with regularly administered questionnaires. We used Cox proportional hazards models to estimate HRs and 95% CIs. RESULTS We documented 17,829 all-cause and 4359 CVD deaths during follow-up. After multivariate adjustment for potential confounders, including demographic factors, disease status, lifestyle, and dietary intakes, higher phosphatidylcholine intakes were associated with an increased risk of all-cause and CVD mortality. HRs (95% CIs) comparing the top and bottom quintiles of phosphatidylcholine intake were 1.11 (1.06, 1.17; P-trend across quintiles < 0.0001) for all-cause mortality and 1.26 (1.15, 1.39; P-trend < 0.0001) for CVD mortality in the combined data of both cohorts. The associations of phosphatidylcholine with all-cause and CVD mortality were stronger in diabetic than in nondiabetic participants (P-interaction = 0.0002 and 0.001, respectively). CONCLUSION These data suggest that higher phosphatidylcholine consumption is associated with increased all-cause and CVD mortality in the US population, especially in patients with diabetes, independent of traditional risk factors.

Effect of Folic Acid, Betaine, Vitamin B₆, and Vitamin B12 on Homocysteine and Dimethylglycine Levels in Middle-Aged Men Drinking White Wine. Nutrients 2016; 8:nu8010034. [PMID: 26771632 PMCID: PMC4728648 DOI: 10.3390/nu8010034] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2015] [Revised: 01/04/2016] [Accepted: 01/06/2016] [Indexed: 11/17/2022] Open
Abstract
Moderate regular consumption of alcoholic beverages is believed to protect against atherosclerosis but can also increase homocysteine or dimethylglycine, which are putative risk factors for atherosclerosis. We aimed (1) to investigate the effect of alcohol consumption on vitamins and several metabolites involved in one-carbon metabolism; and (2) to find the most effective way of decreasing homocysteine during moderate alcohol consumption. Methods: Male volunteers (n = 117) were randomly divided into five groups: the wine-only group (control, 375 mL of white wine daily for one month) and four groups combining wine consumption with one of the supplemented substances (folic acid, betaine, and vitamins B12 or B6). Significant lowering of homocysteine concentration after the drinking period was found in subjects with concurrent folate and betaine supplementation. Vitamin B12 and vitamin B6 supplementation did not lead to a statistically significant change in homocysteine. According to a multiple linear regression model, the homocysteine change in the wine-only group was mainly determined by the interaction between the higher baseline homocysteine concentration and the change in dimethylglycine levels. Folate and betaine can attenuate possible adverse effects of moderate alcohol consumption. Dimethylglycine should be interpreted together with data on alcohol consumption and homocysteine concentration.
