Abstract
INTRODUCTION This study aimed to investigate the relationship between homocysteine (Hcy) and blood pressure variability (BPV) and the relationship between Hcy and left ventricular hypertrophy (LVH) in 102 patients with essential hypertension. METHODS The 102 patients were divided into the Hcy < 10 μmol/L group (n = 47) and the Hcy ≥ 10 μmol/L group (n = 55) according to Hcy concentration. The differences between Hcy and BPV and Hcy and LVH were compared between the two groups. Finally, the correlations between Hcy and BPV and between Hcy and LVH were analyzed. RESULTS The results showed that there were significant differences between Hcy and BPV and between Hcy and LVH in the two groups. Hcy correlated positively with the coefficient of variation in nighttime diastolic blood pressure and night systolic blood pressure standard deviation (nDBPSD), with correlation coefficients of 0.331 and 0.303 (P < 0.001). At the same time, Hcy correlated positively with interventricular septal thickness and left ventricular posterior wall thickness, which were indicators of LVH, with correlation coefficients of 0.350 and 0.352 (P < 0.001). CONCLUSIONS There was a correlation between Hcy and BPV and between Hcy and LVH. Attention should also be paid to blood Hcy and BPV for patients with essential hypertension.

Abstract
This study investigated the long-term antihypertensive effects of esaxerenone, a novel nonsteroidal mineralocorticoid receptor blocker, alone or in combination with a calcium channel blocker (CCB) or a renin-angiotensin system (RAS) inhibitor, in Japanese patients with essential hypertension. Patients were treated with esaxerenone starting at 2.5 mg/day increasing to 5 mg/day if required to achieve blood pressure (BP) targets as a monotherapy or with a CCB or RAS inhibitor. After the first 12 weeks of treatment, an additional antihypertensive agent could be added if required to achieve the target BP; the total treatment period was 28 or 52 weeks. The primary endpoint was a change from baseline in sitting BP. Of the 368 enrolled patients, 245 received monotherapy, and 59 and 64, respectively, took a CCB or RAS inhibitor concurrently. Mean changes from baseline in sitting systolic/diastolic BP (95% confidence intervals) at weeks 12, 28 and 52 were -16.1 (-17.3, -14.9)/-7.7 (-8.4, -6.9), -18.9 (-20.2, -17.7)/-9.9 (-10.7, -9.2), and -23.1 (-25.0, -21.1)/-12.5 (-13.6, -11.3) mmHg, respectively (all P < 0.0001 vs baseline). Similar BP reductions at these weeks were observed between all patient subgroups stratified by age, and the observed decreases in 24-h ambulatory BP were consistent with the efficacy observed in sitting BP. Esaxerenone was also well-tolerated with a rate of hyperkalemia at 5.4% (serum potassium ≥5.5 mEq/L), indicating a good safety profile for treatment over the long-term or in combination with a CCB or RAS inhibitor. In conclusion, esaxerenone may be a promising treatment option for patients with hypertension.

Abstract
INTRODUCTION Proper control of blood pressure reduces the risk of developing cardiovascular and cerebrovascular complications in hypertensive people. However, this control remains mostly unsatisfactory. Although alexithymia has been associated with essential hypertension, no study has analysed the relationship between alexithymia and blood pressure control in drug-treated hypertension. This research aimed to analyse the presence and the characteristics of this relationship, considering both the pharmacological treatment and the achievement of adequate maintenance of blood pressure in a physiological range. METHOD One thousand two hundred and forty-one people participated in the study. Eight hundred and ten were hypertensive patients, and four hundred and thirty-one were normotensive people. The Toronto Alexithymia Scale-20 was used to assess alexithymia. RESULTS Results show that hypertensive people are more alexithymic than normotensive people. According to the presence of pharmacological treatment, treated hypertensive patients are more alexithymic than normotensive and not treated hypertensive patients. Considering the blood pressure control associated with the drug-therapy, people with uncontrolled hypertension are more alexithymic than normotensive and untreated hypertensive people. CONCLUSIONS These findings confirm a relationship between alexithymia and essential arterial hypertension, but they also highlight that alexithymia appears to be associated with higher severity of hypertension. Alexithymia could be a facet of uncontrolled hypertension.

Abstract
INTRODUCTION Early alterations in the cardiovascular system have been described in offspring of hypertensive parents, but with conflicting results. AIM To evaluate the influence of genetic predisposition to hypertension on left ventricular (LV) geometry and function, 30 normotensive male offspring of hypertensive parents (EH+) and 30 matched offspring of normotensive families (EH-), were studied. METHODS All subjects underwent office and 24-h ambulatory blood pressure monitoring (ABPM), conventional and Tissue Doppler Echocardiography (TDE), including assessment of myocardial performance index (MPI). RESULTS EH+ showed an increase in office BP with statistical significance in diastolic BP (84 ± 7 vs 73 ± 6 mmHg; p < 0.05). Relative wall thickness (RWT) was greater in EH+ (0.37 ± 0.05 vs 0.31 ± 0.03; p < 0.05) and significantly related to the EH+ condition at the univariate analysis (p < 0.003), whilst the LV mass index was unchanged (84.3 ± 14 vs 80 ± 17 g/m2; p = NS), suggesting a trend towards concentric remodeling. Systolic and diastolic function, in both ventricles, were superimposable in the two groups. The MPI was higher in EH+ (0.49 ± 0.10 vs 0.45 ± 0.08; p = NS) and significantly correlated to RWT (r = 0.47, p < 0.01). However, at the stepwise multiple regression analysis, only the condition of EH + was independently associated with RWT (p <0.006). RWT, according to ROC curves analysis, predicted the condition of EH+ (cutoff 0.359, specificity 89%, sensitivity 82%). CONCLUSION Current results provide information about LV myocardial performance in EH+ subjects, related to a LV concentric remodeling and to endothelial dysfunction.

Abstract
The purpose of this research is to study the characteristics of the change in the circadian rhythm of macrophage colony-stimulating factor (M-CSF) content in the peripheral blood serum of patients with stage II essential hypertension (EH) based on 5 time points (8:00, 14:00, 20:00, 2:00, and 8:00) and analyze its connection with the frequency of cardiovascular events. Materials and methods Identified levels of M-CSF in the peripheral blood serum of 60 patients with stage II EH, before and after 1 year of antihypertensive therapy using enzyme-linked immunoassays (at 8:00, 14:00, 20:00, 2:00, and 8:00). Results The research demonstrated that stage II EH patients with a medical case history lasting 10-14 years have a greater content of M-CSF in their peripheral blood serum (p > 0.001). Before the start of antihypertensive therapy, they also have an increased variability in the circadian rhythm of M-CSF content in the bloodstream (when compared with healthy individuals) due to an increase at 20:00, decrease at 2:00 and recovery at 8:00. In 70% of those patients taking antihypertensive medication and have reached their target arterial blood pressure, the cytokine decrease stabilizes at 2:00 but the increase at 20:00 remains unchanged. Thirty percent of patients retained the rhythm characteristics of M-CSF content in the blood serum typical of patients before the start of therapy. This is a predictor of an increase in the five-year risk of developing cardiovascular complications, particularly myocardial infarction and acute cerebrovascular accident, in individuals with a comparable risk of cardiovascular complications or death on the Framingham risk score.

Abstract
Introduction: This study aimed to investigate whether mononucleotide polymorphisms of the
angiotensinogen gene at promoter were associated with the
blood-pressure-lowering response to telmisartan treatment. Materials and methods: After a two-week single-blind placebo run-in period, 148 patients with
mild-to-moderate primary hypertension received monotherapy with 80 mg/day of
telmisartan and then were followed up for eight weeks. The -6A/G and -20A/C
polymorphisms of the angiotensinogen gene at promoter were determined
through polymerase chain reaction and restriction fragment length
polymorphsim analysis. The relationship between these polymorphisms and
changes in blood pressure was observed and evaluated after eight weeks of
treatment. Results: There were no significant differences between -6A/G, -20A/C polymorphisms of
the angiotensinogen gene and blood pressure reductions after treatment,
p>0.05. Conclusion: It is suggested that angiotensinogen-6 A/G and angiotensinogen-20 A/C
polymorphisms were not associated with the antihypertensive response to
telmisartan treatment in Chinese patients with hypertension.

Abstract
Background Hypertension is an important risk factor for cardiovascular disease, even in the elderly. Fimasartan is a new non-peptide angiotensin II receptor blocker with a selective type I receptor blocking effect. The objective of this study is to confirm the safety and the non-inferiority of the blood pressure–lowering effect of fimasartan compared with those of perindopril, which has been proven safe and effective in elderly patients with hypertension. Methods This is a randomized, double-blind, active-controlled, two-parallel group, optional-titration, multicenter, phase 3 study comparing the efficacy and safety of fimasartan and perindopril arginine. The study population consists of individuals 70 years old or older with essential hypertension. The primary outcome will be a change in sitting systolic blood pressure from baseline after the administration of the investigational product for 8 weeks. The secondary outcomes will be a change in sitting diastolic blood pressure from baseline and changes in sitting systolic blood pressure and diastolic blood pressure from baseline after the administration of the investigational product for 4, 16, and 24 weeks. The sample size will be 119 subjects for each group to confer enough power to test for the primary outcome. Discussion Research to confirm the efficacy and safety of a new medicine compared with those of previously proven anti-hypertensive drugs is beneficial to guide physicians in the selection of therapeutic agents. If it is confirmed that the new drug is not inferior to the existing drug, the drug will be considered as an option in the treatment of hypertension in elderly patients.

Abstract
Background Genetic and environment play a significant role in the etiology of essential hypertension (EH). Recently STK39 rs3754777, ATP2B1 rs2681472 and rs17249754 have been associated with BP variation and hypertension. In this study we aimed to determine firstly whether index variants were associated with the risk of developing EH in Burkina Faso and secondly to characterize cardiovascular risk markers. Methods We conducted a case-control study with 380 participants including 180 case subjects with EH and 200 control subjects with normal BP. We used TaqMan genotyping assays with probes from Applied Biosystems to genotype polymorphisms using the 7500 Real-Time PCR System. Biochemical parameters were measured using chemistry analyzer COBAS C311. Results T-test showed that cardiovascular risk markers such as body mass index, waist circumference, blood sugar, total cholesterol and triglycerides were significantly higher in hypertensive compared to normotensive (all p < 0.05). Binary logistic regression analysis revealed in decreasing order that overweight, family history of hypertension, central obesity and alcohol intake increased the risk of developing EH (all OR > 3.8; all p < 0.001). In genetic level we observed that individuals carrying the AA+AG genotype of ATP2B1 rs17249754 had a low risk of developing EH than those carrying the GG genotype (OR = 0.48 [95% CI: 0.31–0.75] p = 0.001) and the A allele frequency in the cases was significantly lower than that of the controls (OR = 0.56 [95% CI: 0.38–0.82] p = 0.003). We also observed that ATP2B1 rs17249754 was significantly associated with higher SBP and DPB in case and control groups (GG versus AG + AA; p < 0.05), ATP2B1 rs2681472 was significantly associated with higher SBP only in case and control group (AA versus AG + GG; p < 0.05), STK39 rs3754777 was not significantly associated with any of the BP traits (CC versus CT + TT; p > 0.05). Conclusion Our results confirmed the significant association of ATP2B1 rs17249754 with the risk of developing EH in Burkinabe and showed an increase of cardiovascular risk markers levels in subjects with EH.

Abstract
One major cause of cardiac mortality is heart disease caused by hypertension. The formation of cyclic adenosine monophosphate (cAMP) is inhibited by calcium-sensitive receptor (CaSR) activation which increases intracellular Ca2+ concentrations and suppresses renin release. As we know, renin-angiotensin system (RAS) is closely related to development of essential hypertension (EH). Therefore, we focused on exploring the roles of NPSR568 (R568)-activated CaSR in cardiac remodeling of spontaneously hypertensive rats (SHRs), as well as the activity of classic and novel RAS. Wistar-Kyoto rats (WKYs) and SHRs were treated by R568 for four and eight weeks, respectively, and their blood pressure (BP), echocardiographic values, heart-to-body weight ratio (HW/BW%), and left ventricle-to-body weight ratio (LVW/BW%) were evaluated. Then Masson’s trichrome staining and hematoxylin and eosin staining as well as RT-qPCR analysis of β-isoform of myosin heavy chain and brain natriuretic peptide mRNA expression were performed. A Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay and analysis of apoptosis marker proteins were used to assess the extent of myocardial apoptosis. The CaSR expression and the activity of classic and novel RAS were examined by immunohistochemistry, western blotting, and enzyme-linked immunosorbent assay. The present study revealed that the development of hypertension was accompanied by increased BP, apoptosis, hypertrophy, and fibrosis, along with decreased expression of CaSR, decreased novel RAS, and increased classic RAS in myocardial tissues. R568 administration for four and eight weeks reduced BP and myocardial remodeling and reversed the low expression of CaSR; moreover, classic RAS was suppressed and novel RAS was activated in the myocardium. Taken together, these data indicate that R568 may effectively inhibit EH myocardial remodeling by inhibiting classic RAS and activating novel RAS in SHRs. Impact statement Our study reveals that low calcium-sensitive receptor (CaSR) expression is associated with the occurrence and development of essential hypertension-mediated myocardial remodeling. The activation of CaSR can reverse adverse myocardia remodeling by inhibiting local classical renin-angiotensin system (RAS) and activating novel RAS in cardiac tissues. CaSR is closely related to many cardiovascular diseases, but its specific mechanism remains not to be elucidated. To date, CaSR has not been investigated with regard to cardiovascular treatment; however, given the important relationship between CaSR and cardiovascular disease, CaSR regulators can be potential drugs for the treatment of cardiovascular disease.

Abstract
Essential hypertension (EH), a major cause of cardiovascular diseases, is an important public health issue. However, the molecular mechanisms involved in EH remain unknown. Circular RNA (circRNA) is a novel promising biomarker for the disease. The purpose of the present study was to determine the expression of circRNAs in the blood of EH patients and to evaluate the performance of circRNA for early diagnosis of EH. A total of 178 subjects were recruited in the case-control study. Initial screening was done by using the Agilent human circRNA microarray followed by qRT-PCR validation. Finally, miRNAs were combined with circRNAs to create a new early prediction model for EH. The expression level of hsa_circ_0126991 in EH patients was significantly higher in comparison with healthy controls (p < 0.0001). Using the interaction of miR-10a-5p in combination with hsa_circ_0126991 led to a sensitivity of 0.708, a specificity of 0.764, and combined area under the curve of 0.774 (95% CI: 0.705-0.843) for early diagnosis of EH. In summary, the present study uncovered a novel perspective that hyperexpression of hsa_circ_0126991 is correlated with the risk of EH and may serve as a stable biomarker for early diagnosis of EH.

Abstract
Background Essential hypertension can cause many kinds of cardiovascular diseases. The pathogenesis of essential hypertension is very complex, and the mechanism is still unclear. The microRNAs have been identified as novel biomarkers for pre-diagnosis and prognosis of hypertension. However, the kinds of microRNAs that can be used as specific biomarkers for hypertension are unknown. Methods and results Plasma samples were isolated from Uyghur subjects with essential hypertension and the healthy individuals. Microarray was used to identify differentially expressed microRNAs. The microarray data were clustered and annotated with online software. The target genes of differentially expressed microRNAs were also analyzed. The microarray results were further verified by quantitative real-time PCR. We identified 257 microRNAs that were differentially expressed between patients with essential hypertension and the healthy individuals. These microRNAs had a total of 6580 target genes. The 47 microRNAs that had target genes, including 24 up-regulated and 23 down-regulated microRNAs, were further screened out to construct a reference set of potential microRNA biomarkers. Most of the 47 microRNAs were located at chromosome 19 (40 microRNAs) and chromosome 1 (45 microRNAs). Their target genes were mainly enriched in metal ion binding, transcription regulation, cell adhesion and junction, indicating that these candidate microRNAs may regulate mineral ion binding and cell communication process of essential hypertension. The quantitative real-time PCR results of miR-198 and miR-1183 (which were the two most significantly up-regulated microRNAs by microarray), and, miR-30e-5p and miR-144-3p (which were the two most significantly down-regulated microRNAs by microarray) were consistent with the microarray results. Conclusions A reference set of potential microRNA biomarkers that may be involved in essential hypertension is constructed. Our study may provide experimental evidence for further studying the mechanism of essential hypertension.

Abstract
BACKGROUND Essential hypertension is an important risk factor for the development of cardiovascular disease. Important candidate genes such as NOS3 gene have been widely studied and reported to be associated with essential hypertension (HTN) in human populations. AIM We aim in this study to analyze the relationship between NOS3 -786T/C, a common genetic variant and HTN in a sample of the Algerian population of the Oran city. METHODS A case-control study has been performed in 154 subjects including 77 hypertensives and 77 normotensives. The recruitment of these subjects was done in local Health Centers of the city of Oran, West Algeria. HTN was defined as elevated systolic blood pressure SBD≥140 mmHg and or sustained diastolic blood pressure DBP≥90 mmHg, measured using an Omron® Automatic BP Monitor - M-3W machine. Consents were obtained from all participants. Polymerase chain reaction (PCR) combined with restrictive fragment length polymorphism (RFLP) was used to genotype the NOS -786T/C variant. RESULTS The distribution of the allelic frequencies did not differ between cases and controls (OR = 1.48; 95%CI [0.94-2.32], P = 0.09). However, after adjustment with the age, sex, and body mass index, we observed significant association between NOS -786C allele and HTN status (OR = 2.08; 95%CI [1.18-3.66], P = 0.01). CONCLUSION Our results indicate that the C allele of the NOS3 gene is associated with increased risk of essential hypertension in this sample of the Algerian population of the Oran city. Further validation in larger samples is needed to confirm this finding.

Abstract
BACKGROUND Besides the traditional risk factors, hematological changes may be involved in the development of arterial hypertension and in its pathogenesis. METHODS The study, conducted on a sample of 545 subjects, 215 with hypertension and 330 witnesses, were evaluated for peripheral blood parameters in western Algeria; Logistic regression analysis was used to predict hypertension with hematological parameters. RESULTS The characters studied related significantly; lower red blood cell levels have a three-and-a-half-fold risk of developing hypertension compared to those who have normal red blood cell counts (OR = 3.64, 95% CI = 1.37-9.65, p < 0.05). Subjects who have mean corpuscular volume rate below 80 fl are more exposed to hypertension (OR = 13.58, 95% CI = 4.68-39.41, p = 0.000). The mean corpuscular hemoglobin concentration reveals that subjects who have a lower than normal (<27 pg) are once less exposed to hypertension (OR = 0.04, 95% CI = 0.01-0.13, p = 0.000). Subjects who have lower platelet count than normal are twelve times more exposed to hypertension (OR = 12.13, 95% CI = 1.45-101.18, P = 0.021). Finally, the increase in sedimentation rate at one hour increases the risk of hypertension by 56.63 times compared to subjects with normal sedimentation rate (OR = 56.63, 95% CI = 3.37-597.33, P = 0.001). CONCLUSIONS Hematological profile associated with essential hypertension retained Red blood cells ratio, mean corpuscular volume, mean corpuscular hemoglobin concentration, platelet ratio, and sedimentation rate at one hour.

Abstract
OBJECTIVE Non-alcoholic fatty liver is a chronic liver disease in which fat is deposited in the liver, causing an inflammation called non-alcoholic steatohepatitis (NASH), and fibrosis. NASH is associated with metabolic syndrome (MS) and other cardiovascular risk factors. The aim of this study was to analyse the epidemiological features of NASH within a hypertensive population, with a high prevalence of MS, and to determine the features related to NASH. METHODS The computerised records were collected from 3,473 patients from Mostoles University Hospital's Hypertension Unit in order to perform a retrospective, cross-sectional study. NASH was considered as ultrasound-detected fatty liver disease along with serum levels of alanine aminotransferase or aspartate aminotransferase 1.5 times above normal values, having ruled out other causes of liver disease: alcohol abuse, autoimmune hepatitis, drug toxicity, virus and hemochromatosis. A univariate, multivariate, and ANOVA analysis were performed to assess the effect of the studied features on the response of interest. RESULTS The cohort included 2,242 patients (51.3% men). NASH was present in 255 patients (11.4%) of whom 71% were men. MS was detected in 52.6% of patients (69.4% in the NASH group, and 50.5% in the non-NASH group, P=.001). Prevalence of type 2 diabetes mellitus was 11.5% (16.5% in the NASH group, and 10.8% in the non-NASH group, P=.01). In a multivariate analysis, waist circumference, MS, body mass index, type 2 diabetes mellitus, age, fasting serum insulin, and serum ferritin were associated with NASH. ANOVA revealed that NASH and transaminases were also significantly associated with components of metabolic syndrome. CONCLUSIONS In the population studied, MS, type 2 diabetes mellitus, and several components of MS were independently associated with NASH. Therefore, NASH can be considered as the liver manifestation of MS in patients with arterial hypertension.

Abstract
INTRODUCTION Hypertension is caused by increased cardiac output and/or increased peripheral resistance. Areas covered: The various mechanisms affecting cardiac output/peripheral resistance involved in the development of essential hypertension are covered. These include genetics; sympathetic nervous system overactivity; renal mechanisms: excess sodium intake and pressure natriuresis; vascular mechanisms: endothelial cell dysfunction and the nitric oxide pathway; hormonal mechanisms: the renin-angiotensin-aldosterone system (RAAS); obesity, obstructive sleep apnea (OSA); insulin resistance and metabolic syndrome; uric acid; vitamin D; gender differences; racial, ethnic, and environmental factors; increased left ventricular ejection force and hypertension and its association with increased basal sympathetic activity - cortical connections. Expert commentary: Maximum association of hypertension is found with sympathetic overactivity which is directly or indirectly involved in different mechanisms of hypertension including RAAS, OSA, obesity, etc.. It is not overt sympathetic activity but disturbed basal sympathetic tone. Basal sympathetic tone arises from hypothalamus; possibly affected by cortical influences. Therefore, hypertension is not merely a disease of circulatory system alone. Its pathogenesis involves alteration in ANS (autonomic nervous system) and likely in cortical-hypothalamic connections. Assessment of ANS and cortical-hypothalamic connections may be required for better understanding of hypertension.

Abstract
Hypertensive patients with normal glucose tolerance (NGT) but 1-h post-load plasma glucose ≥ 155 mg/dl (1-h high), during an oral glucose tolerance test (OGTT), show higher insulin resistance and multiple target organ damages. Experimental and clinical studies demonstrate that silybin presents anti-inflammatory and metabolic effects, improving insulin resistance and endothelial dysfunction. This study aims to evaluate the effects of the complex silybin-vitamin E and phospholipids on inflammatory, metabolic and vascular parameters in NGT 1-h high hypertensive patients. This is a pilot, single arm, interventional, longitudinal study enrolling 50 Caucasian NGT 1-h high hypertensive outpatients, 27 men and 23 women, age range 42-60 years (mean + SD = 52 ± 7). After 6 months of silybin intake, there is a significant improvement in metabolic profile. The glucose response during OGTT significantly improves (AUCglucose0-120 309.6 ± 63.4 at baseline vs 254.6 ± 35.5 at the follow-up, ∆ = - 55, 95% CI from - 67 to - 43, p < 0.0001), so as insulin response (AUCinsulin0-120 238.2 ± 99.1 vs 159.3 ± 44.9, ∆ = - 78.9, 95% CI from - 100.0 to - 57.8, p < 0.0001), in accordance with the increase of insulin sensitivity index Matsuda. Silybin intake is associated with a significant reduction of both clinical and central systolic blood pressure, with betterment in clinical and central pulse pressure and reduction of arterial stiffness parameters. In conclusion, this study demonstrates that silybin may improve the metabolic aspect and vascular damage in NGT 1-h high hypertensive patients who are at higher metabolic and cardiovascular risk. Thus, in these patients, silybin might strengthen the effect of antihypertensive drugs giving further cardiovascular protection.

Abstract
Essential hypertension (EH) is a principal contributing factor in
worldwide cardiovascular disease mortality. Although interventions that minimize
environmental risk factors for EH are associated with reduced cardiovascular
disease, such approaches are limited for individuals with high genetic EH risk. In
this study, we investigated possible associations between ACE2 polymorphisms and
hypertension-related target organ damages in south Xinjiang, China. Four hundred and
two hypertensive patients were enrolled as study participants in an EH group, and
233 normotensive individuals were enrolled as control subjects. Participants were
recruited from the south Xinjiang region. Fourteen ACE2 polymorphisms were genotyped
by matrix-assisted laser desorption ionization time-of-flight mass spectrometry.
Risk genotypes of rs2074192 (TT+CT, OR = 1.72, 95% CI: 1.17–2.53), rs2106809 (TT,
OR = 1.71, 95% CI: 1.13–2.58), rs4240157 (CC+CT, OR = 1.99, 95% CI: 1.17–3.41),
rs4646155 (TT+CT, OR = 1.94, 95% CI: 1.06–3.54), rs4646188 (TT+CT, OR = 3.25, 95%
CI: 1.95–5.41), rs4830542 (CC+CT, OR = 1.88, 95% CI: 1.10–3.23), and rs879922
(CC+CG, OR = 4.86, 95% CI: 2.74–8.64) were associated with EH. Hypertensive patients
carrying the control genotype of rs2074192 (CC, OR = 2.37, 95% CI: 1.28–4.39) were
associated with CAS ≥50%, while those carrying a high-EH-risk genotype of rs4240157
(OR = 2.62, 95% CI: 1.24–5.54), rs4646155 (OR = 2.44, 95% CI: 1.16–5.10), or
rs4830542 (CC+CT, OR = 2.20, 95% CI: 1.03–4.69) were associated with atrial
fibrillation (AF), larger left atrial diameter, and higher levels of
renin–angiotensin–aldosterone system (RAAS) activation (renin and angiotensin I/II).
In conclusion, the ACE2 variant rs2074192 was associated with EH and EH with CAS
≥50%, while 3 ACE2 variants (rs4240157, rs4646155, and rs4830542) were associated
with EH- and hypertension-related AF and left atrial remodeling in south Xinjiang,
China.

Abstract
The kidneys are thought to contribute to the pathogenesis of primary hypertension, but hypertension is also known to cause target organ damage in the kidney. Noninvasive methods to capture possible changes in the kidney related to hypertension are limited. A new program that has been used to quantify the heterogeneity and percent echogenicity in renal ultrasound images was implemented to assess patients with hypertension. Children and adolescents <21 years with primary hypertension diagnosed by ambulatory blood pressure monitoring were compared with normotensive age- and sex-matched controls. Renal ultrasound images were evaluated by a technique that measured pixels of gray-scale images and transformed them into a binary map, which was converted to a heterogeneity index (HI) and percent echogenicity score. This study included 99 children with hypertension and 99 control subjects. Body mass index (BMI) was greater in the hypertension group. Average HI for hypertension was significantly higher than in controls (1.37 ± 0.19 vs. 1.2 ± 0.23, P = .001), while echogenicity scores were not different (26.6 ± 8.9 vs. 25.9 ± 10, P = .8). In regression analysis adjusting for BMI z-score and race, hypertension was associated with greater HI compared with controls (β = 0.11, 95% confidence interval 0.03-0.18, P = .005). In a model adjusted for age, sex, and BMI z-score in the hypertension group only, no ambulatory blood pressure monitoring measures were associated with HI or echogenicity scores (P > .05).HI was significantly greater in the hypertension group compared with normotensive controls. HI may be a novel method to detect changes in the kidney related to hypertension.

Abstract
The hypothalamic paraventricular nucleus (PVN) is a crucial region involved in maintaining homeostasis through the regulation of cardiovascular, neuroendocrine, and other functions. The PVN provides a dominant source of excitatory drive to the sympathetic outflow through innervation of the brainstem and spinal cord in hypertension. We discuss current findings on the role of the PVN in the regulation of sympathetic output in both normotensive and hypertensive conditions. The PVN seems to play a major role in generating the elevated sympathetic vasomotor activity that is characteristic of multiple forms of hypertension, including primary hypertension in humans. Recent studies in the spontaneously hypertensive rat model have revealed an imbalance of inhibitory and excitatory synaptic inputs to PVN pre-sympathetic neurons as indicated by impaired inhibitory and enhanced excitatory synaptic inputs in hypertension. This imbalance of inhibitory and excitatory synaptic inputs in the PVN forms the basis for elevated sympathetic outflow in hypertension. In this review, we discuss the disruption of balance between glutamatergic and GABAergic inputs and the associated cellular and molecular alterations as mechanisms underlying the hyperactivity of PVN pre-sympathetic neurons in hypertension.

Abstract
Background Cardiovascular benefits by reversing environmental risks factors for essential hypertension (EH) and dyslipidemia could be weaken by high genetic risk. We investigated possible associations between ACE2 polymorphisms and dyslipidemia in patients with EH. Methods Four hundred and two hypertensive patients were enrolled in an EH group and 233 normotensive individuals were enrolled as control group from the Xinjiang region of China. Fourteen ACE2 polymorphisms were genotyped by Matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Results Participants carrying T allele (TT + CT) of rs2074192 (P = 0.006), rs4646155 (P = 0.030) and rs4646188 (P < 0.001), C allele (CT + CT or CC + CG) of rs4240157 (P = 0.012), rs4830542 (P = 0.020) and rs879922 (P < 0.001) and TT genotype of rs2106809 (P = 0.012) were associated with EH. Meanwhile,ACE2 SNPs also exhibited association with dyslipidemia but exhibited obvious heterogeneity. rs1978124 (TT + CT, P = 0.009), rs2106809 (TT, P = 0.045), rs233575 (CC + CT, P = 0.018), rs4646188 (CC, P = 0.011) and rs879922 (CC + CG, P = 0.003) were association with increased LDL-C (≥1.8 mmol/L). rs2106809 (CC + CT, P < 0.001), rs2285666(TT + CT, P = 0.017), rs4646142(CC + CG, P = 0.044), rs4646155(TT + CT, P < 0.001) and rs4646188(TT + CT, P = 0.033) were association with decreased HDL-C (< 1.0 mmol/L). rs2074192 (TT + CT, P = 0.012), rs4240157 (CC + CT, P = 0.027), rs4646156 (AA+AT, P = 0.007), rs4646188 (TT + CT, P = 0.005), rs4830542 (CC + CT, P = 0.047) and rs879922 (CC + CG, P = 0.001) were association with increased TC (≥5.2 mmol/L). rs2106809 (P = 0.034) and rs4646188 (P = 0.013) were associated with hypertriglyceridemia. Further, ischemic stroke was more prevalent with rs4240157 (CC + CT, P = 0.043), rs4646188 (CC + CT, P = 0.013) and rs4830542 (CC + CT, P = 0.037). In addition, rs2048683 and rs6632677 were not association with EH, dyslipidemia and ischemic stroke. Conclusion The ACE2 rs4646188 variant may be a potential and optimal genetic susceptibility marker for EH, dyslipidemia and its related ischemic stroke.

Abstract
Background Nuclear genes or family-based mitochondrial screening have been the focus of genetic studies into essential hypertension. Studies into the role of mitochondria in sporadic Chinese hypertensives are lacking. The objective of the study was to explore the relationship between mitochondrial DNA (mtDNA) variations and the development of maternally inherited essential hypertension (MIEH) in China. Methods Yangzhou residents who were outpatients or in-patients at the Department of Cardiology in Northern Jiangsu People’s Hospital (Jiangsu, China) from June 2009 to June 2015 were recruited in a 1:1 case control study of 600 gender-matched Chinese MIEH subjects and controls. Genomic DNA was isolated from whole blood cells. The most likely sites for hypertension were screened using oligodeoxynucleotides at positions 7908–8816, purified and subsequently analyzed by direct sequencing according to the revised consensus Cambridge sequence. The frequency, density, type and conservative evolution of mtDNA variations were comprehensively analyzed. Results We found a statistical difference between the two groups for body mass index, waist circumference, abdominal circumference, triglyceride, low-density lipoprotein cholesterol, fasting blood glucose, uric acid, creatinine and blood urea nitrogen (P < 0.05). More amino-acid changes and RNA variants were found in MIEH subjects than the controls (P < 0.01). The detection system simultaneously identified 40 different heteroplasmic or homoplasmic mutations in 4 genes: COXII, tRNALys, ATP8 and ATP 6. The mtDNA variations were mainly distributed in regions of ATP6 binding sites, and the site of highest mutation frequency was m. 8414C > T. Three changes in single bases (C8414T in ATP8, A8701G in ATP6 and G8584A in ATP6) were significantly different in the MIEH patients and the controls (P < 0.001). The m.8273_8281del mutation was identified from 59 MIEH patients. Conclusions Our results indicate that novel mtDNA mutations may be involved in the pathological process of MIEH, and mitochondrial genetic characteristics were identified in MIEH individuals.

Abstract
Objective: To explore the prevalence and clinical characteristics of postprandial hypotension(PPH) in patients with essential hypertension and coronary heart disease. Methods: A total of 197 patients with essential hypertension and coronary heart disease, who had been treated in the First Department of Cardiology of the Second Hospital of Hebei Medical University from December, 2013 to December, 2014 were included. The patients' blood pressure before breakfast, lunch and dinner and 30, 60, 90, 120 minutes after the meal were monitored. Subjects were classified into PPH group (n=37) and non-PPH group (NPPH, n=160) according to postprandial decrease in systolic blood pressure, to explore the clinical characteristics and related factors and the major adverse cardiac and cerebral vascular events of PPH. Results: Among 197 patients, 37 cases (18.8%) showed at least once postprandial decline in systolic blood pressure greater than and equal to 20 mmHg. The incidence of PPH after breakfast and dinner were higher than lunch (P<0.05). There was no significant difference in the incidence of PPH among different age groups, among patients accompanied with different diseases, and among patients with different dining position (all P>0.05). According to the baseline systolic blood pressure, patients can be divided into 4 groups(<120 mmHg, 120-129 mmHg, 130-139 mmHg, >140 mmHg), the higher the level of the baseline systolic blood pressure was, the higher the incidence of PPH was. And the incidence of major adverse cardiac and cerebral vascular events in patients during hospitalization were increased by PPH. Conclusions: The prevalence of PPH in the patients with essential hypertension and coronary heart disease is 18.8%. The incidence of PPH after breakfast and dinner is higher than lunch. The baseline systolic blood pressure is considered to be the risk factor of PPH. And PPH could lead to an increase of the incidence of major adverse cardiac and cerebral vascular events.

Abstract
BACKGROUND The aim of our study was to determine whether prediabetes increases cardiovascular (CV) risk compared to the non-prediabetic patients in our hypertensive population. Once this was achieved, the objective was to identify relevant CV prognostic features among prediabetic individuals. METHODS We included hypertensive 1652 patients. The primary outcome was a composite of incident CV events: cardiovascular death, stroke, heart failure and myocardial infarction. We performed a Cox proportional hazard regression to assess the CV risk of prediabetic patients compared to non-prediabetic and to produce a survival model in the prediabetic cohort. RESULTS The risk of developing a CV event was higher in the prediabetic cohort than in the non-prediabetic cohort, with a hazard ratio (HR) = 1.61, 95% CI 1.01-2.54, p = 0.04. Our Cox proportional hazard model selected age (HR = 1.04, 95% CI 1.02-1.07, p < 0.001) and cystatin C (HR = 2.4, 95% CI 1.26-4.22, p = 0.01) as the most relevant prognostic features in our prediabetic patients. CONCLUSIONS Prediabetes was associated with an increased risk of CV events, when compared with the non-prediabetic patients. Age and cystatin C were found as significant risk factors for CV events in the prediabetic cohort.

Abstract
Essential hypertension (EH) is a major risk factor for cardiovascular disease. Despite considerable efforts to elucidate the pathogenesis of EH, there is an imperious need for novel indicators of EH. This study aimed to develop a method to predict potential biomarkers of EH from the point of view of network. A pathway-based gene-gene interaction (GGI) network model was constructed and analyzed, containing 116 nodes and 1272 connections. The nodes represented EH-related genes, and that connections represented their interactions. The network showed a small-world property and uneven degree distribution, suggesting that a few highly interconnected hubs played a vital role in EH. An inherent hierarchy and assortative mixing pattern were also observed in the network. GNAS, GNB3, PF4 and PPBP showed the highest values of degrees and centrality indices, and were chosen as potential biomarkers of EH. A two-mode network model based on the potential biomarkers demonstrated that hemostasis and GPCR ligand binding pathway were key pathways contributing to EH. Results of this study improve our current understanding of the molecular mechanisms driving EH. The selected genes and pathways have the potential to be used in the diagnosis and treatment of EH. Moreover, the combination of pathway analysis and complex network methodology provides a novel strategy for searching new genetic indicators of complex diseases.

Abstract
BACKGROUND In recent years, using metabolomics technology to study hypertension has made some progress. However, in actual clinical studies, there are few studies on hypertension related metabonomics with human urine as samples. In this study, the urine samples of patients with essential hypertension (EH) were studied by comparing with healthy people to explore the changes of urine metabolites between hypertensive patients and healthy people in order to find potential biomarkers and metabolic pathways. METHODS An ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) technology was used to analyze the urine metabolites of 75 cases of essential hypertension group (EH) and 75 cases of healthy control group (HC). RESULTS According to the PLS-DA pattern recognition analysis, substances with significant differences (P < .05) between the EH group and the HC group were screened out, including 10 potential biomarkers such as L-methionine. The metabolic pathways involved were amino acid metabolism, fatty acid metabolism steroid hormone, biosynthesis and oxidative stress. CONCLUSION The non-targeted metabolomics based on UPLC-Q-TOF/MS technology can effectively identify the differential metabolites of potential biomarkers in the urine of essential hypertensive patients and provide a theoretical basis for the treatment of clinical hypertension.

Abstract
OBJECTIVE The results of studies on the association between tumor necrosis factor-a -308G/A (TNF-a -308G/A) polymorphism, and susceptibility to essential hypertension are controversial. To derive a more precise estimation, we conducted a meta-analysis of all similar articles. METHODS The summary effect odds ratios and 95% confidence intervals were obtained. Funnel plots and Egger's test were used to estimate publication bias, and heterogeneity was assessed by the chi-square-based Q-test and I2 test. RESULTS Nine studies (with 1437 cases and 1487 controls) were included. In the overall analysis, the combined results showed that there were significant differences in genotype distribution between essential hypertension cases and controls, AA+GA versus GG (OR = 1.53, 95% CI: 1.25-1.88, p < 0.00001). In the stratified analysis by country, we found that essential hypertension cases had a significantly higher frequency of AA+GA versus GG (OR = 1.47, 95% CI: 1.18-1.81, p = 0.0004) than control in the Asian population. CONCLUSIONS This meta-analysis supports previous findings that TNF-a -308G/A polymorphism may increase the risk of essential hypertension, at least in the Asian population.

Abstract
Essential arterial hypertension is a disease with distinct yet unexplored inflammatory component. Our aim was to assess the role of chemokine genes and their interaction in its development. Genotyping of polymorphic markers in six chemokine genes (CXCL13, CCL8, CCL16, CCL17, CCL18, and CCL23) was performed in the group of 522 men of Tatar ethnic origin from the Republic of Bashkortostan, Russia (213 patients with essential hypertension and 309 healthy individuals without history of cardiovascular disease). We found a strong association of CXCL13 rs355689*C allele with essential hypertension under additive (OR 0.56, PFDR = 0.008) and dominant (OR 0.41, PFDR 4.38 × 10- 4) genetic model. The analysis of gene-gene interactions revealed 12 allele/genotype combinations that remained significantly associated with essential hypertension after correction for multiple testing was applied, and each of these combinations included CXCL13 rs355689 polymorphism. Our results indicate that CXCL13 rs355689 polymorphism is strongly associated with essential hypertension in the ethnic group of Tatars, alone and in combination with polymorphic markers in other chemokine genes.

Abstract
OBJECTIVE The comparison of antihypertensive effects between azilsartan and olmesartan in patients with essential hypertension has been investigated in several studies. The results were not consistent. We performed this meta-analysis determining the antihypertensive effect of azilsartan versus olmesartan in patients with essential hypertension. METHODS Pubmed, Web of Science, and Cochrane Central were searched for all published randomized studies comparing the antihypertensive effects between azilsartan and olmesartan in patients with essential hypertension. RESULTS The antihypertensive effects were assessed in 1402 patients included in five trials. The reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan (weighted mean differences (WMD) - 2.15 (95% confidence interval (CI), - 3.78, - 0.53) mm Hg, p < 0.01). There was no significant difference in reduction of office diastolic blood pressure between azilsartan and olmesartan (WMD - 0.99 (95% CI, - 2.06, 0.08) mm Hg, p > 0.05). The reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan at same dose for both drugs (WMD - 2.24 (95% CI, - 4.03, - 0.44) mm Hg, p < 0.05), whereas there was no significant difference in reduction of office diastolic blood pressure between azilsartan and olmesartan (WMD - 0.55 (95% CI, - 1.76, 0.66) mm Hg, p > 0.05). CONCLUSIONS This meta-analysis provides the evidence that the reduction of office systolic blood pressure treated with azilsartan was greater than olmesartan in patients with essential hypertension. These findings suggest the importance of strict designed randomized controlled trials in determining antihypertensive effects of angiotensin II receptor blockers in clinical practice.

Abstract
Human cytomegalovirus (HCMV) infection, chronic inflammation and oxidative stress, the renin-angiotensin system (RAS), endothelial function, and DNA methylation play roles in the pathogenesis of essential hypertension (EH); however, the mechanism by which HCMV predisposes patients to hypertension remain unclear. Our group previously demonstrated an association between EH and HCMV infection in Kazakh Chinese. Here, we investigated the relationship between HCMV infection and other clinicopathological features in 720 Kazakh individuals with or without hypertension (n=360 each; age: 18-80). Multiple linear and logistic regression analyses were used to determine the associations between HCMV infection, clinical characteristics, and EH. Notably, patients with EH, particularly those with HCMV infection, exhibited a marked increase in tumor necrosis factor-α (TNF-α) and 8-hydroxy-2-deoxyguanosine (8-OHDG) levels, but a decrease in endothelial nitric oxide synthase (eNOS) and renin levels. Similarly, elevated TNF-α and 8-OHDG levels were independent predictors of increased HCMV antibody titers, whereas eNOS and renin were negatively correlated with the latter. Moreover, serum angiotensin-converting enzyme (sACE, ACE) methylation was increased, whereas 11-β hydroxysteroid dehydrogenase 2 (HSD11β2; HSD3B2) methylation was decreased in patients with EH who were also infected with HCMV. A positive correlation between HSD3B2 methylation and HCMV IgG titer and blood pressure was additionally observed, whereas angiotensin-converting enzyme (ACE) methylation was inversely correlated with blood pressure. Collectively, these data indicate that HCMV may contribute to EH development in the Kazakh Chinese by increasing TNF-α and 8-OHDG levels, suppressing eNOS and renin, and manipulating HSD3B2 and ACE methylation.

Abstract
INTRODUCTION We hypothesized that hypertensive patients harbor a higher risk of urinary bladder (UB) cancer. MATERIAL AND METHODS We performed a population-based cohort study on adults using a National Health Insurance Research Database (NHIRD) dataset. Hypertension and comparison non-hypertensive (COMP) groups comprising 39,618 patients each were propensity score-matched by age, sex, index date, and medical comorbidities. The outcome was incident UB cancer validated using procedure codes. We constructed multivariable Cox models to derive adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). Cumulative incidence was compared using a log-rank test. RESULTS During a total follow-up duration of 380,525 and 372,020 person-years in the hypertension and COMP groups, 248 and 186 patients developed UB cancer, respectively, representing a 32% increase in the risk (aHR, 1.32; 95% CI, 1.09-1.60). Hypertensive women harbored a significantly increased risk of UB cancer (aHR, 1.55; 95% CI, 1.12-2.13) compared with non-hypertensive women, whereas men with hypertension had a statistically non-significant increased risk (aHR, 1.22; 95% CI, 0.96-1.55). The sensitivity analysis demonstrated that the increased risk was sustained throughout different follow-up durations for the entire cohort; a statistical increase in the risk was also noted among hypertensive men. CONCLUSION This nationwide population-based propensity score-matched cohort study supports a positive association between hypertension and subsequent UB cancer development.

Abstract
OBJECTIVE The objective of this study was to summarize the evidence regarding the relationship between obstructive sleep apnoea syndrome (OSAS) and the risk of essential hypertension. METHODS The study was a dose-response meta-analysis of observational studies. The PubMed, Embase, CNKI, VIP and CBM databases were searched to collect relative studies examining the relationship between OSAS and the risk of essential hypertension. Studies were retrieved from database establishment through September 2016, and new literature published between September 2016 and May 2017 was later supplemented. Linear and non-linear dose-response models were used to assess the relationship between apnoea-hypopnea index (AHI), which was used to reflect the severity of OSAS, and the risk of essential hypertension. Stata 13.0 was used for the meta-analysis. RESULTS Six prospective cohort studies and one case-control study were included, for a total sample size of 6098. The dose-response meta-analysis showed that a high AHI significantly increased the risk of essential hypertension compared with a low AHI (odds ratio (OR) = 1.77, 95% confidence interval (CI) (1.30, 2.41), p = 0.001). The linear dose-response meta-analysis showed that the risk of essential hypertension increased by 17% for every 10 events/h increase in the AHI (OR = 1.17, 95% CI (1.07, 1.27), p = 0.001), and the results of the non-linear dose-response meta-analysis showed that the risk of essential hypertension increased with increasing AHI value. CONCLUSION A potential dose-response relationship exists between the severity of OSAS and the risk of essential hypertension. This relationship should be considered when developing prevention measures for essential hypertension.

Abstract
The arteries calcification index is a quantitative, mathematically estimated parameter characterizing the total amount of calcium within atherosclerotic plaques in the walls of arteries. The objective is to determine a relationship between exposure to cigarette smoke and the carotid arteries calcification index in patients with essential hypertension. The tested group included 66 patients with essential hypertension: 19 active smokers (subgroup A), 20 non-smokers, environmentally exposed to cigarette smoke (subgroup B) and 27 persons without exposure to cigarette smoke (subgroup C). The tested group was subjected to computed tomography angiography of carotid arteries. Evaluation of the carotid arteries calcification indexes was conducted. The average value of the total calcification index of the carotid arteries (CAci) amounted to 368.28 ± 384.21. In subgroup A and B in relation to subgroup C, CAci was significantly higher. In summary, active and passive smoking in patients with essential hypertension may be associated with a higher calcification index of carotid arteries.

Abstract
Background The present study sought to explore the relationship of common cardiovascular disease risk factors and noncoding RNAs with essential hypertension (EH). Methods A total of 402 EH patients and 402 gender- and age-frequency matched healthy controls were enrolled in this study. Each participant received a questionnaire survey, physical examination and laboratory tests. Quantitative real-time polymerase chain reaction (qPCR) was performed to assess relative expression levels of six noncoding RNAs (NR_027032, NR_034083, NR_104181, miR-126, miR-143 and miR-145) in peripheral blood leucocytes. Multiple logistic regression analysis was used to estimate the risk of having EH between hypertensive and non-hypertensive patients. Results Analysis showed that participants with anxiety, high body mass index, abdominal obesity and family history of hypertension had higher risk for EH, whereas those with bland diet and occupational physical activities had lower risk for EH. qPCR assays showed that NR_027032 (P = 0.015) and NR_034083 (P = 0.004) were significantly reduced in EH patients compared with controls, whereas NR_104181 (P = 0.007), miR-143 (P = 0.005) and miR-145 (P = 0.015) were significantly elevated. After controlling the cardiovascular risk factors, multivariate analysis showed that lower expression levels of NR_034083 and higher expression levels of NR_104181 and miR-143 were risk factors for EH. Conclusions EH is a result of environmental and epigenetic factors. Strikingly, NR_034083, NR_104181 and miR-143 may be correlated with the risk for EH development; therefore, epigenetic markers could be used to measure hypertension levels to help elucidate the pathogenesis of EH.

Abstract
OBJECTIVE To investigate changes in gene expression profiles in the hypothalamus related to the effects of acupuncture at the Renying (ST 9) acupoint in spontaneously hypertensive (SH) rats. METHODS We randomly divided 18 SH rats into Renying (ST 9) group and model control group, 9 body weight-matched Wistar-Kyoto rats were used as blank controls. Acupuncture was performed manually for 20-min daily over 28 d in the Renying (ST 9) group. Rat Gene 2.0 array technology was used for the determination of gene expression profiles and the screened key genes were verified by real-time quantitative polymerase chain reaction (RT-PCR) analyses. RESULTS The different groups exhibited differential gene expression: compared with the blank control group, 48 genes were up-regulated and 91 genes were down-regulated in the model group; compared with the model group, 79 genes were up-regulated and 80 genes were down-regulated in Renying (ST 9) group. The RT-PCR results of the key genes including Chi3l1, Ephx2, Klk1, 5-HT1A and Cbs were consistent with that of gene chip analysis. CONCLUTION Acupuncture at Renying (ST 9) could significantly lower the blood pressure of SH rats and affect their hypothalamic gene expression profile. Genes associated with the contraction of vascular smooth muscle and the regulation of inflammation, neurotransmitters may be involved in acupuncture's antihypertensive mechanism.

Abstract
The abnormalities of blood pressure (BP) nocturnal decline have been found to be predictive for carotid plaque and lacunar infarction in patients with hypertension. In this study, BP dipping patterns in postmenopausal females with hypertension were investigated. The nocturnal decline of systolic BP (SBP) was evaluated using 24-hour ambulatory BP monitoring (ABPM). A total of 163 postmenopausal females were eventually included in our study. The prevalence of reverse-dipper BP pattern was 32.3% in females with menopause age in their 40s and 40% in their 50s. However, after multivariate logistic regression analysis, menopause age was shown to be an independent risk factor for BP reverse dipping (Odds ratio [OR] 1.148; 95%CI 1.020 - 1.292; P = 0.020). Moreover, menopause age was negatively correlated with the decline rate of nocturnal SBP (r = -0.159; P < 0.05) and diastolic BP (r = -0.161; P < 0.05). Our study suggested that the menopause age might serve as a risk factor for reverse-dipper BP pattern in postmenopausal females with hypertension.

OBJECTIVE The comparison of antihypertensive effects between telmisartan and candesartan in patients with essential hypertension has been investigated in several small studies. The results were not consistent. We performed this meta-analysis determining the antihypertensive effect of telmisartan versus candesartan in these patients. METHODS We searched Pubmed, Web of Science, and Cochrane Central for all published studies comparing the antihypertensive effects between telmisartan and candesartan in patients with essential hypertension. RESULTS The antihypertensive effects were assessed in 302 patients included in 4 trials with a mean follow-up of 10 ± 4 weeks. There were no significant differences between telmisartan and candesartan in reduction of systolic blood pressure (SBP) and diastolic BP (DBP) in patients with essential hypertension (weighted mean differences (WMD) for SBP 1.98 mm Hg (95% confidence interval (CI), -0.53, 4.49), p > 0.05; WMD for DBP 0.26 mm Hg (95% CI, -1.65, 2.16), p > 0.05), respectively. In a sub-analysis including 2 randomized studies, there was not a significant difference for the reduction of SBP (WMD 0.90 (95% CI, -2.88, 4.68) mm Hg, p > 0.05) or DBP (WMD -0.80 (95% CI, -3.40, 1.81) mm Hg, p > 0.05) treated with telmisartan or candesartan. CONCLUSIONS This meta-analysis provides the evidence that the antihypertensive effects of telmisartan and candesartan are similar on SBP and DBP reduction in patients with essential hypertension, suggesting that strict designed randomized controlled trial would be helpful to compare antihypertensive effects of angiotensin II receptor blockers (ARBs) and improve the choice of ARBs in antihypertensive therapy.

Abstract
BACKGROUND Genetic factors have a vital influence on the pathogenesis of hypertension. In this retrospective study, we aimed to evaluate the association of ADRB1 and CYP2D6 polymorphisms with antihypertensive effects and perform an analysis of their contribution to hypertension risk. METHODS A total of 261 healthy individuals and 261 essential hypertension patients treated with metoprolol for 12 weeks were enrolled. ADRB1 and CYP2D6 genotypes were identified by xTAG liquid chip technology. We used multivariate logistic regression and a generalized linear mixed model to assess hypertension-related risk factors. RESULTS The allele frequencies of ADRB1 and CYP2D6 variants were 59.8% and 64.6% in the essential hypertension group and 70.3% and 65.9% in the controls, respectively. The genotype and allele distribution of ADRB1 were significantly different between the 2 groups (P < 0.05), but there was no significant difference in CYP2D6 distribution (P = 0.91 and 0.88). By logistic regression analysis, high fasting plasma glucose, smoking, high triglyceride and the Gly/Gly polymorphism in Arg389Gly ADRB1 all emerged as independent risk factors for hypertension. Additionally, the ADRB1 genotype played a major role in the antihypertensive effect of metoprolol and the patients with the Gly389Gly genotype showed a significantly better response to metoprolol than did those with a heterozygous ADRB1 mutation (Arg389Gly) (P = 0.027). CONCLUSIONS The results demonstrate that Gly/Gly polymorphism in Arg389Gly ADRB1 was an independent risk factor together with high fasting plasma glucose, smoking and high triglyceride; moreover, the patients who carried the Gly389Gly genotype had a significantly improved metoprolol antihypertensive effect than those with ADRB1.

Abstract
BACKGROUND Essential hypertension (EH) is a high prevalence with multifactorial diseases. Human studies on the impact of genes on this disease are just in the initial stage, the mechanism of gene regulation is still remains unclear. Circular RNAs (circRNAs) as a continuous cycle of covalent closure, RNA molecules added to the 3'-5' end covalently bound by the formation of incidental event. CircRNAs may be an important biomolecule in revealing the molecule regulate mechanisms of EH. METHODS The circRNAs were selected and validated with qRT-PCR followed. Our experiment was conducted with case-control studies among 200 EH participants. The t-test was used to evaluate the different expression of circRNAs and miRNAs, the significance of which was set as p < 0.05. RESULTS The hsa_circ_0037911 expression level in EH cases were significantly higher than healthy controls (p = 0.005). There was still important significance when adjusted by logistic regression (adjusted p = 0.026). We also found that hsa_circ_0037911 was an effective marker of EH (area under curve = 0.627; p = 0.002). The levels of hsa_circ_0037911 were significantly differences in gender, BMI, smoking and drinking among EH cases. There was a positive correlation between Serum creatinine (Scr) and hsa_circ_0037911. CONCLUSIONS Our findings suggested that higher expression hsa_circ_0037911 may be key circRNAs for EH development by changing the concentration of Scr and could be a stable biomarker for early diagnosis of EH.

Abstract
BACKGROUND The aim of this study was to determine and compare cardiovascular risks by assessing arterial stiffness in children with essential hypertension and white coat hypertension. METHODS Paediatric patients followed up with essential hypertension and white coat hypertension diagnoses and with no established end organ damage were involved in the study. Arterial stiffness in children included in the study was evaluated and compared by using the oscillometric device (Mobil-O-Graph) method. RESULTS A total of 62 essential hypertension (34 male, 28 female), 38 white coat hypertension (21 male, 17 female), and 60 healthy controls (33 male, 27 female) were assessed in the present study. Pulse wave velocity of the essential hypertension, white coat hypertension, and control group was, respectively, as follows: 5.3±0.6 (m/s), 5.1±0.4 (m/s), 4.3±0.4 (m/s) (p<0.001); augmentation index outcomes were, respectively, determined as follows: 21.3±6.5, 19.3±6.4, 16.0±0.3 (p<0.001). Pulse wave velocity and augmentation index values of children with essential hypertension and white coat hypertension were found to be higher compared with the control group. This level was identified as correlated with the duration of hypertension in both patient groups (p<0.01). CONCLUSION Arterial stiffness in children with essential hypertension and white coat hypertension was impaired compared with healthy children. This finding has made us think that white coat hypertension is not an innocent clinical situation. This information should be taken into consideration in the follow-up and treatment approaches of the patients.

Abstract
Background: ATP2B1 and STK39 have been introduced as essential hypertension candidate genes. The association of these genes' variations have not been studied in Iranian population yet. Here we aimed to investigate the association of ATP2B1 rs2681472 and STK39 rs35929607 polymorphisms with the risk of hypertension in an Iranian population. Methods: We included 400 individuals in our case-control study: 200 cases with essential hypertension and 200 healthy sex and age matched controls. All subjects were genotyped for rs2681472 and rs35929607 using a PCR-RFLP method. Genotype and allele frequencies were compared between the two groups using chi-squared test. The association was further assessed under log-additive, dominant and recessive genetic models. Results: There was no association between rs2681472 and rs35929607 polymorphisms and risk of essential hypertension in our population (p>0.05). There was also no association between the studied polymorphisms and hypertension under different genetic models. Conclusion: Our study indicated that rs2681472 of ATP2B1 and rs35929607 of STK39 may not have a significant effect on the risk of essential hypertension in Iranian population. More studies are still needed to validate our results.

Abstract
Essential hypertension is a leading global public health issue, billions of people suffered from it every year. Recently, multiple evidence suggests that DNA methylation play an important role in regulating blood pressure. Here, we tested the risk for essential hypertension conferred by single nucleotide polymorphisms (SNPs) within DNA methyltransferase 1 (DNMT1). Three loci (rs2228611, rs2228612, and rs16999593) were selected to be analyzed in 3410 cases and 1307 normal controls in southern Chinese aged 60 or above. No significant association with essential hypertension was observed for rs2228612 and rs16999593. A higher risk of essential hypertension was found in the minor A allele of rs2228611 in the codominant and recessive model (P < 0.05). After stratified by sex, this association was found in male but not female. Furthermore, this difference was abolished after BMI adjustment in the whole population and reduced in male. In addition, the mutation rate of rs2228611 was higher in the obesity group compared with the normal weight group of male. Intriguingly, rs2228611 was also a risk factor of essential hypertension in normal weight male. These findings indicated that rs2228611 might contribute to male hypertension via BMI-dependent mechanisms in obesity male and BMI-independent mechanisms in normal weight male.

Abstract
BACKGROUND AND AIM Increasing evidence confirms that potassium channels are essential for lymphocyte activation, suggesting an involvement in the development of hypertension. Moreover, chronic inflammation is regarded as a direct or indirect manifestation of hypertension, highlighting the theoretical mechanisms. In this study, we investigated changes in KCa3.1 potassium channel expression in the blood of hypertensive and healthy Kazakh people in north-west China. METHODS Flow cytometry technology was used for T-lymphocyte subtype analysis. Changes in the messenger RNA and protein expression of the KCa3.1 potassium channel in CD4+ T lymphocytes were detected using real-time quantitative polymerase chain reaction and western blots, using CD4+ T-cell samples from hypertensive Kazakh patients divided into candesartan and TRAM-34 treatment groups, and healthy case controls. Peripheral blood CD4+ T lymphocytes were activated and proliferated in vitro and then incubated for 0, 24, and 48 h under various treatment conditions. Changes in CD4+ T-lymphocytic proliferation were determined using Cell Counting Kit-8 and electron microscope photography. RESULTS Expression of KCa3.1 was significantly higher in the hypertensive patients than in the controls (p < 0.05). Compared with the healthy group, Kazakh hypertensive patients had a reduced proportion of CD4+ T lymphocytes (p < 0.05).Candesartan and TRAM-34 intervention for 24 h and 48 h inhibited the expression of Kv1.3 and KCa3.1 at mRNA and protein level (p < 0.05). CONCLUSIONS Increase in functional KCa3.1 channels expressed in CD4+ T lymphocytes of Kazakh patients with hypertension was blocked by candesartan, providing theoretical support for hypertension treatment at the cellular ion channel level. Candesartan may potentially regulate hypertensive inflammatory responses by inhibiting T-lymphocytic proliferation and KCa3.1 potassium channel expression in CD4 + T lymphocytes.

Abstract
BACKGROUND The relationship between environmental exposure of non-smokers to cigarette smoke and the coronary artery calcium scores has not been sufficiently documented. The aim of the study was to identify the relationship between environmental exposure to cigarette smoke and the risk of coronary artery disease (CAD) estimated non-invasively through measurement of coronary artery calcium score by computed tomography in patients with essential hypertension. MATERIAL AND METHODS The study was conducted on 67 patients with essential hypertension, non-smokers environmentally exposed to cigarette smoke (group A) and on 67 patients with essential hypertension, non-smokers not exposed to cigarette smoke (group B), selected using the case to case. Environmental exposure to cigarette smoke was evaluated using a questionnaire. The risk of development of coronary artery disease was estimated non-invasively through measurement of coronary artery calcium score (CACS) by computed tomography. RESULTS Group A was characterised by significantly higher CACS and left anterior descending (LADCS) calcium scores than group B. Compared to group B, group A had significantly higher percentage of patients with significant risk of CAD estimated on the basis of CACS values, and significantly lower percentage of patients with practically no risk of CAD estimated with the same method. Advanced age, peripheral artery diseases and environmental exposure to cigarette smoke are independent risk factors associated with increased CACS and LADCS values. In addition, higher BMI and hypercholesterolemia are independent risk factors for increased values of LADCS. CONCLUSIONS In patients with essential hypertension environmental exposure to cigarette smoke may result in elevated risk of coronary artery disease estimated non-invasively through measurement of coronary artery calcium score by computed tomography.

Abstract
BACKGROUND Essential hypertension (EH) is influenced by various environmental and genetic factors. Nitric oxide is important for the functional integrity of the vascular endothelium and is produced in endothelial cells by the enzyme endothelial nitric oxide synthase (eNOS). EH has a strong genetic component, and the NOS3 gene, which encodes eNOS, represents an interesting candidate for contribution to the phenotype. The most clinically relevant polymorphisms in the NOS3 gene are rs1799983 in exon 7 (encoding Glu298Asp), a variable number tandem repeat (VNTR) in intron 4, and rs2070744 (T-786C) in the promoter region. This study aims to investigate the association between these three polymorphisms in the NOS3 gene and EH in Sudanese patients. METHODS Hypertensive patients (n = 157) > 18 years of age with established hypertension from various hospitals in Khartoum, and controls (n = 85) > 18 years of age and with blood pressure measurements <140/90, were included in this case control study. Genotypes at the NOS3 variants were determined using TaqMan and polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analyses. Genotype and allele frequencies were compared between the two groups by χ2 analysis, and differences were expressed as odds ratios with 95% confidence intervals (CIs). P values <0.05 were considered statistically significant. RESULTS The rs2070744 polymorphism in NOS3 was found to be associated with EH in the Sudanese population as the patients group had higher frequency of CC genotype compared with the controls (6.6% vs 6.1%, p = 0.02). Considering a dominant inheritance model, the frequency of TC + CC genotypes in patients was significantly higher than that in the control subjects (52.6% vs 34.1%, respectively; p < 0.01), with an odds ratio (95% CI) of 2.14 (1.23-3.74). In addition, the C allele was more frequent in the patients than the control group (29.6% vs 20%, p = 0.03, OR = 1.84 (1.15-2.93)). The c allele of intron 4 VNTR was reported in >1% of the Sudanese population under study. CONCLUSION The results of this study indicated that the rs2070744 polymorphism in NOS3 may be a genetic susceptibility factor for EH in the Sudanese population. The c allele of intron 4 VNTR is not rare in the Sudanese population.

Abstract
BACKGROUND Hypertensive nephropathy, a leading cause of declining kidney function, is a multifactorial process not well understood. In order to elucidate biological processes and identify novel macromolecular components crucially involved in the process of kidney damage, the application of system biology approaches, like proteomics, is required. METHODS Proteomic studies were performed using the renal parenchyma of spontaneously hypertensive rats (SHR) and their normotensive Wistar Kyoto controls. Animals were sacrificed at early time intervals (6, 13, and 20 weeks after birth), the renal tissue extract was subjected to two-dimensional gel electrophoresis, differential expressed proteins were identified, and altered pathways were evaluated. One specific protein, chloride intracellular channel 4 (CLIC4), not implicated so far in the development of hypertension and nephrosclerosis, was further studied by Western blotting, immunohistochemistry and immunofluorescence. RESULTS Proteomic analysis identified several pathways/processes and organelles (mitochondria) as being affected from the early stages of hypertension. CLIC4 was overexpressed in SHR at all 3 time intervals examined. This finding was confirmed by Western blotting and by immunohistochemistry and immunofluorescence; these morphological techniques demonstrated that CLIC4 was almost exclusively localized at the apical surface of the proximal tubular epithelial cells. CONCLUSIONS Our studies provide evidence that major changes occur in the renal parenchyma from early stages of the development of hypertension. The overexpression of CLIC4 suggests that alterations in the proximal tubular compartment during hypertension should be further examined and that CLIC4 may be a useful early marker of renal tubular alterations due to elevated blood pressure.

Abstract
The aim of the study was to determine the relationship between exposure to cigarette smoke and the morphology of atherosclerotic plaques in the extracranial arteries assessed by computed tomography angiography in patients with hypertension. The study included 61 hypertensive patients: 17 active smokers (group A), 18 non-smokers, declaring environmental exposure to tobacco smoke (group B), and 26 non-smokers, not declaring exposure to cigarette smoke (group C). The number of segments with plaques was significantly higher in group A compared to groups B and C. The number of segments with non-calcified and mixed plaques was significantly higher in group A and group B than in group C. A positive correlation between cigarette-years and the number of segments with atherosclerotic plaques was noted. In summary, both active smoking and environmental exposure to tobacco smoke appear to increase the number of segments of the extracranial arteries with non-calcified and mixed atherosclerotic plaques.

Abstract
BACKGROUND/AIM The two-way cause and effect relationship existing between high blood pressure and kidney dysfunction is currently a well-documented phenomenon with patients in either category being almost equally predisposed to the other pathology. Our goal was to assess the renal function capacity of hypertensive patients in our setting. METHODS This cross-sectional descriptive study involved the determination of blood pressure levels and the collection of blood and urine samples for the measurement of renal function markers. Hypertensive patients who came for medical follow-up constituted the study participants, and were enrolled consecutively into the study from February to May 2015. Data analysis was performed using the SPSS 20.0 software, and significant differences were determined at p < 0.05. RESULTS The prevalence of elevated creatinine and urea levels were 35 and 27%. Eighty percent of the participants had a decreased glomerular filtration rate (≤90 mL/min/1.73 m3), with at least 36% recording less than 60 mL/min/1.73 m3. Proteinuria and glucosuria were recorded in 15% and 8% of the participants, respectively. The mean diastolic pressure was observed to be significantly higher in participants with proteinuria (p = 0.016), and participants' weight directly correlated with systolic blood pressure (p = 0.015). Furthermore, the mean estimated glomerular filtration rate was relatively lower in participants >60 years compared to those <60 years (p < 0.001). CONCLUSION Renal function is often perturbed in hypertensive patients, and good blood pressure control may reduce the progression of renal impairment. Thus, a systematic evaluation of renal function in addition to blood pressure control in hypertensive patients is indispensable towards effectively reducing the occurrence of renal events and preventing end-stage renal disease.

Abstract
Catecholamines play a major role in atherothrombotic mechanisms in essential hypertension. Alpha2B-adrenergic receptors (α2B-ARs) are implicated in the pathophysiology of platelet aggregation. In this study, we evaluated platelet α2B-AR gene expression levels in patients with well-controlled essential hypertension compared with normal individuals and investigated their association with increased arterial stiffness. Fifty-nine patients with well-controlled essential hypertension (34 men, mean age 65 ± 9 years) and 26 normotensives (19 men, mean age 64 ± 8 years) were included in the study. For each patient, carotid-femoral pulse wave velocity (PWV) and carotid-radial PWV were evaluated. In addition, blood samples were obtained and platelets were isolated. The α2B-AR gene expression levels in platelets were examined by real-time polymerase chain reaction for each participant. Well-controlled hypertensive patients showed significantly higher gene expression levels of α2B-Rs in platelets compared with normotensives (34.7 ± 29.5 vs 17.6 ± 12.5, respectively, P = .005). Interestingly, we found that carotid-femoral PWV and carotid-radial PWV were positively correlated with platelet α2B-R gene expression levels (r = 0.59, P < .001, and r = 0.39, P = .002, respectively).Platelet α2B-R gene expression levels are increased in patients with well-controlled essential hypertension compared with normotensives and are correlated with increased PWV in those patients. Our data indicate an association of arterial stiffness and platelet α2B-Rs gene expression and indicate the need for further research.

Abstract
A 54-year old married woman was diagnosed with rheumatoid arthritis in 2002, essential hypertension in 2008, type-2 diabetes in 2011 and gangrene over 2nd toe of right foot. She underwent conventional management in private hospitals. Her symptoms, began with moderate to severe pain associated with swelling, stiffness (more in the morning) in multiple joints especially over small joints. In July-2014 she visited our college hospital with the complaints of pain, mild swelling and stiffness over multiple joints associated with poor quality of sleep (QOS) and quality of life (QOL). Subject received integrative Naturopathy and Yoga therapies (INYT) with conventional medicine daily for 10-days. After 10-days, improvements in pain, blood sugar, depression, anxiety, stress, QOS, QOL, blood analysis with normal blood pressure (BP) was observed. This suggests that INYT could be considered as an adjuvant to conventional medicine in RA associated with type-2 diabetes and essential hypertension.
