Abstract
BACKGROUND Oxidative stress has been shown to play a critical role in the pathogenesis of hypertension. Paeonol, a major phenolic component extracted from Moutan Cortex, exerts a beneficial effect in preventing cardiovascular disease via reducing oxidative stress. The present study investigated the protective mechanism of paeonol against high blood pressure in spontaneous hypertension rats (SHRs). METHODS Wistar-Kyoto (WKY) rats and SHRs received vehicle or peaonol in the drinking water for 5 weeks. Blood pressure was measured by tail-cuff plethysmography and oxidative stress in kidney and vascular tissue was examined by enzyme-linked immunosorbed assay. The functions of angiotensin II type 1 receptors (AT1R) in the kidney and mesenteric artery were measured by natriuresis and vasoconstrictor response, respectively. RESULTS Compared with vehicle-treated WKY rats, vehicle-treated SHRs exhibited higher blood pressure, increased oxidative stress, accompanied by exaggerated diuretic and natriuretic responses to candesartan (AT1 receptor antagonist) and vasoconstrictor responses to angiotensin II (Ang II). Moreover, SHRs had higher ACE and AT1R in the kidney and mesenteric artery, and higher Ang II and lower renin levels. Interestingly, paeonol treatment reduced the candesartan-induced increase in diuresis and natriuresis and vasoconstrictor responses to Ang II, and lowered blood pressure in SHRs, accompanied by reducing AT1R protein expression in the kidney and mesenteric artery of SHR, and Ang II levels in plasma and increasing renin levels in renal cortex. In addition, these changes were associated with reducing oxidative stress. CONCLUSIONS The present study suggests that paeonol improves renal and vascular AT1R functions by inhibition of oxidative stress, thus lowering blood pressure in SHRs.

Effects of a social support family caregiver training program on changing blood pressure and lipid levels among elderly at risk of hypertension in a northern Thai community. PLoS One 2021; 16:e0259697. [PMID: 34847170 PMCID: PMC8631627 DOI: 10.1371/journal.pone.0259697] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 10/07/2021] [Indexed: 11/18/2022] Open
Abstract
Hypertension is becoming increasingly prevalent among the elderly. Family caregivers play an important role in caring for elderly people and empowering them to care for themselves. This study’s goal was to see how social support training for family caregivers affected changes in hypertension, total cholesterol, and high-density lipoprotein (HDL), and how such support led to the prevention of hypertension behaviors among the elderly in rural areas. This was a quasi-experimental study with 268 elderly people at risk of hypertension and their caregivers. Sixty seven pairs of elderly people and their caregivers were assigned to the intervention and control groups. Baseline data were collected in November 2020. The intervention group received the Social Support Family Caregiver Training Program (SSFCTP), while the control group received a regular program from the local health authority. The activity lasted 12 weeks, with home visits and telephone check-ups along the way, and data collection took place after the program ended. The final data were collected three months after the end of the intervention. An analysis of repeated measures ANOVA showed the overall effect of the SSFCTP on knowledge, self-efficacy, health care behaviors, and blood pressure among elderly people during three different time periods (p<0.05). Furthermore, the intervention program had a time-dependent effect on knowledge, blood pressure, and total cholesterol levels (p<0.05). In terms of caregiver outcomes, there was an overall difference among the degrees of knowledge, self-efficacy, and behaviors toward health care displayed by elderly hypertensive patients during the three different time periods (p<0.05). The average knowledge and self-efficacy of the participants improved after the intervention. As a result, better self-care behaviors and lower blood pressure and total cholesterol levels were observed among the elderly participants after the intervention. The programs emphasized the importance of caregivers’ roles in providing social support, boosting confidence, and encouraging participation in caring, monitoring, and assisting the elderly in controlling blood pressure and other health issues.

Alternation of brain intrinsic activity in patients with hypertensive retinopathy: a resting-state fMRI study. Aging (Albany NY) 2021; 13:21659-21670. [PMID: 34516404 PMCID: PMC8457564 DOI: 10.18632/aging.203510] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 08/14/2021] [Indexed: 12/05/2022]
Abstract
Objective: To investigate the changes of amplitude of low-frequency fluctuation (ALFF) in brain regions of patients with hypertensive retinopathy by using resting-state functional magnetic resonance imaging (rs-fMRI) and change in the relationship of ALFF value with potential emotional and psychological changes. Methods: Thirty-one patients with hypertensive retinopathy (HR) (16 men and 15 women) and 31 healthy controls (HCs; 16 men and 15 women) matched for age, sex, and weight were enrolled in the research. The changes in mean ALFF values could reflect brain activity between HR patients and HCs. We used the independent samples t-test to evaluate different demographic and general information between the two groups. Two-sample t-test was used to detect differences of mean ALFF values in the brain region between the two groups using the same software. Results: The ALFF values in the brain areas of HR and HCs were different. HR patients had lower ALFF value in the left medial superior frontal gyrus and left middle frontal gyrus than the HCs. The higher ALFF values were found in the cerebellum (left inferior and right superior lobes, vermis) and left inferior temporal gyrus of the HR patients than the controls. Conclusion: Our findings showed fluctuations in ALFF values in the HR patients’ brain regions. ALFF values reflect over or reduced activity in brain regions. Abnormal ALFF values in these brain areas can predict early HR development, preventing the malignant transformation of hypertensive microangiopathy.

Abstract
BACKGROUND Evidence showed that Tai Chi may have beneficial effects among hypertensive individuals, although the results are not convincing. We aim to conduct a high-quality clinical trial with 24-h BP measurement to provide robust evidence of Tai Chi for essential hypertension. METHODS This is an open-label single-center randomized controlled trial with 3 parallel arms. We will compare Tai Chi with walking and waiting-list control. We will recruit 234 hypertensive patients with mild to moderate essential hypertension and randomly assign them to 3 different groups. Participants in Tai Chi group will receive a group-format Yang style 24-form Tai Chi exercise program, 3 sessions per week for 12 weeks. The walking group will be asked to walk, 3 sessions per week for 12 weeks. The waiting-list group will not receive any interventions and/or exercise training. The primary outcome is the change in average 24-h systolic blood pressure (SBP) between baseline and 12 weeks after randomization. The secondary outcomes include 24-h Diastolic Blood Pressure (DBP), average SBP and average DBP during the daytime and night-time, blood pressure (BP) variability, SBP load and DBP load, circadian rhythm of BP, and morning BP surge, endothelial functional indicators, home measured BP, quality of life, adverse events and so on. DISCUSSION We expect findings of this trial will provide important insight into application of Tai Chi as an effective and acceptable method for hypertensive patients. Successful completion of this proposed study will also contribute to promotion of Tai Chi in the community in the future.

A Smartphone App (mDASHNa-CC) to Support Healthy Diet and Hypertension Control for Chinese Canadian Seniors: Protocol for Design, Usability and Feasibility Testing. JMIR Res Protoc 2020; 9:e15545. [PMID: 32238343 PMCID: PMC7316441 DOI: 10.2196/15545] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 11/12/2019] [Accepted: 12/09/2019] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND This proposed study aims to translate the Dietary Approach to Stop Hypertension with Sodium (Na) Reduction for Chinese Canadians (DASHNa-CC), a classroom-based, antihypertensive, dietary educational intervention, to an innovative smartphone app (mDASHNa-CC). This study will enable Chinese Canadian seniors to access antihypertensive dietary interventions anytime, regardless of where they are. It is hypothesized that senior Chinese Canadians will be satisfied with their experiences using the mDASHNa-CC app and that the use of this app could lead to a decrease in their blood pressure and improvement in their health-related quality of life. OBJECTIVE The goal of this study is to design and test the usability and feasibility of a smartphone-based dietary educational app to support a healthy diet and hypertension control for Chinese Canadian seniors. METHODS A mixed-method two-phase design will be used. The study will be conducted in a Chinese immigrant community in Toronto, Ontario, Canada. Chinese Canadian seniors, who are at least 65 years old, self-identified as Chinese, living in Canada, and with elevated blood pressure, will be recruited. In Phase I, we will design and test the usability of the app using a user-centered approach. In Phase II, we will test the feasibility of the app, including implementation (primary outcomes of accrual and attrition rates, technical issues, acceptability of the app, and adherence to the intervention) and preliminary effectiveness (secondary outcomes of systolic and diastolic blood pressure, weight, waist circumference, health-related quality of life, and health service utilization), using a pilot, two-group, randomized controlled trial with a sample size of 60 participants in a Chinese Canadian community. RESULTS The study is supported by the Startup Research Grant from Nipissing University, Canada. The research ethics application is under review by a university research ethics review board. CONCLUSIONS The study results will make several contributions to the existing literature, including illustrating the rigorous design and testing of smartphone app technology for hypertension self-management in the community, exploring an approach to incorporating traditional medicine into chronic illness management in minority communities and promoting equal access to current technology among minority immigrant senior groups.

Abstract
OBJECTIVE The relationship among sleep quality, sleep duration and hypertension prevalence is controversial in different age groups and genders. This study aimed to investigate sleep quality, sleep duration and their association with hypertension prevalence among low-income oldest-old in a rural area of China. METHODS A cross-sectional survey was conducted in a representative sample of 1066 adults aged 80-99 years in 2017. Logistic regression analysis was performed. RESULTS Among males, sleep durations of <6 h and 6-<7 h were significantly associated with hypertension prevalence, with odds ratios (ORs) of 3.15 (95% confidence interval (CI) 1.37 to 7.23) and 2.38 (95% CI 1.22 to 4.63), respectively. Among females, only the sleep duration of <6 h was associated with increased OR of hypertension of 3.49 (95% CI 1.50 to 8.09). Poor sleep quality was associated with hypertension for both genders (ORmen 1.67, 95% CI 1.12 to 2.49; ORwomen 1.91, 95% CI 1.29 to 2.82). For women, a combination of poor sleep quality and any group of sleep duration, except for 7-<8 h, was associated with higher hypertension prevalence. For men, only the combination of poor sleep quality and short sleep duration (<7 h) was associated with high hypertension prevalence. CONCLUSION Short sleep duration and poor sleep quality are associated with hypertension prevalence of oldest-old. The prevention of hypertension in older adults should be investigated from the perspective of sleep improvement.

Abstract
Objectives: To determine the facilitators and barriers influencing healthy eating behaviours among aged Chinese-Canadians with hypertension. Methods: After attending five weeks of dietary educational training (Dietary Approach to Stop Hypertension with Sodium (Na) Reduction for Chinese Canadians; DASHNa-CC), 30 aged Chinese-Canadian participants partook in a telephone interview. Participants were asked to name three facilitators and three barriers that influenced their ability to follow the DASHNa-CC intervention. Telephone transcripts were then analyzed and coded using computer software and categorized into personal, familial, community, and societal facilitators or barriers. Results: Personal factors included health problems, motivation, effects of healthy diet, health-related careers, and dietary habits. Family factors included family structure, support from family members, and critical health events involving family members or relatives. Community factors consisted of educational materials, friends, primary care physicians, and online social networks. Societal factors included accessibility to grocery stores and restaurants. Conclusions: Aged Chinese-Canadian immigrants experience unique facilitators of and barriers to healthy eating, which may warrant further attention from healthcare professionals when educating patients in a culturally-sensitive manner.

Abstract
OBJECTIVE To explore the trend of hypertension prevalence and related factors in Yi people from 1996 to 2015. METHODS Three successive cross-sectional surveys were conducted in Liangshan Yi Autonomous Prefecture in 1996, 2007 and 2015, respectively. A total of 8448 participants aged 20-80 years (5040 Yi farmers, 3408 Yi migrants) were included in final analysis. RESULTS Overall, the age-standardised prevalence of hypertension in migrants was significantly higher than in farmers. Furthermore, the age-standardised prevalence rates increased from 10.1% to 15.3% to 19.6% in Yi migrants and from 4.0% to 6.3% to 13.1% in Yi farmers during 1996 to 2007 to 2015. The highest 2015-to-1996 ratio of age-standardised hypertension prevalence was in male farmers (ratio=4.30), whereas despite the highest prevalence of hypertension, the equivalent figure in male migrants was 1.57. The older age, overweight and obesity were persistent risk factors of hypertension in three periods. After adjusted for age and body mass index, the difference of hypertension prevalence between 1996 and 2015 then vanished in male migrants (OR=1.335; 95% CI: 0.884 to 2.015) and female farmers (OR=1.267; 95% CI: 0.590 to 2.719). The disparities of hypertension prevalence between Yi migrants and farmers were not statistically significant in all subgroups when adjusted for age, body mass index and education. CONCLUSIONS Over the past two decades, the hypertension prevalence in Yi people has significantly increased. Yi migrants were more likely to be hypertensive than Yi farmers which was predominantly driven by the discrepancy of body mass index between them.

Abstract
Hypertension is highly prevalent in Chinese Canadians and diet has been identified as an important modifiable risk factor for hypertension. The current anti-hypertensive dietary recommendations in hypertension care guidelines lack examination of cultural factors, are not culturally sensitive to ethnic populations, and cannot be translated to Chinese Canadian populations without cultural considerations. Guided by Leininger's Sunrise Model of culture care theory, this paper investigates how cultural factors impact Chinese Canadians' dietary practice. It is proposed that English language proficiency, health literacy, traditional Chinese diet, migration and acculturation, and Traditional Chinese Medicine influence Chinese Canadians' dietary practices. A culturally congruent nursing intervention should be established and tailored according to related cultural factors to facilitate Chinese Canadians' blood pressure control. In addition, further study is needed to test the model adapted from Sunrise Model and understand its mechanism.

Abstract
OBJECTIVE To examine the independent and combined associations of sleep duration and sleep quality with hypertension in a middle-aged and older Chinese population. METHODS We included 21,912 individuals aged 62.2 years at baseline from September 2008 to June 2010, and they were followed until October 2013. Sleep duration was self-reported and sleep quality was evaluated with questions designed according to the Pittsburgh Sleep Quality Index. Hypertension was defined as blood pressure ≥140/90 mmHg, or self-reported physician diagnosis of hypertension, or self-reported current use of antihypertensive medication. RESULTS In the cross-sectional analyses, the odds ratio of hypertension prevalence was significantly elevated (OR = 1.13, 95% CI = 1.03-1.24) in those who slept less than 7 h after adjusting for sex, age, body mass index, midday napping, cigarette smoking and sleep quality. It was particularly evident among males (OR = 1.19, 95% CI = 1.01-1.40) and individuals who were thin (OR = 2.00, 95% CI = 1.01-3.93) with full adjustment. The association was also found for sleep duration of 9∼<10 h after adjusting various covariates (OR = 1.14, 95% CI = 1.04-1.27). In addition, impaired sleep quality was only associated with hypertension in obese individuals (OR = 1.25, 95% CI = 1.02-1.50), not in other subgroups. However, no significant association was detected in any category of sleep duration or sleep quality in all models in the prospective analyses, and the results remained unchanged in the subgroup analyses of sex, age and body mass index. CONCLUSIONS The results of this study provide limited support for association of sleep duration and sleep quality with hypertension in middle-aged and older Chinese. Further studies are needed to confirm the results.

The effect of body mass index and physical activity on hypertension among Chinese middle-aged and older population. Sci Rep 2017; 7:10256. [PMID: 28860562 PMCID: PMC5579023 DOI: 10.1038/s41598-017-11037-y] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Accepted: 08/18/2017] [Indexed: 02/07/2023] Open
Abstract
Few studies have been conducted to explore the independent and combined associations of body mass index (BMI) and physical activity with risk of hypertension in Chinese population. A cross-sectional study of 5291 individuals (aged ≥ 40 years) selected using multi-stage sampling method was conducted from October 2013 to December 2015. In the present analysis, 55.64% of the participants were women, and the mean age of participants was 55.37 ± 10.56. Compared with individuals in normal group, the risks of hypertension were nearly double in overweight subjects (odds ratio [OR] 1.77, 95% confidence interval [CI] 1.53–2.05) and more than three times higher in obese subjects (3.23, 2.62–4.13). Multi-adjusted odds for hypertension associated with low, moderate, and high physical activity were 1.44 (1.17–1.86), 1.40 (1.09–1.79) and 1.000, respectively. In comparison with normal weight subjects who reported high levels of physical activity, subjects who reported both low levels of physical activity and obesity showed the highest risk of hypertension (5.89, 3.90–8.88). In conclusion, both elevated BMI and reduced physical activity appear to play an important role in the risk of hypertension among Chinese middle-aged and older population. The risk of hypertension associated with overweight and obesity can be reduced considerably by increased physical activity levels.

Abstract
The objectives of this article were to provide a comprehensive overview of the recruitment experience and participant characteristics in an antihypertensive dietary educational intervention pilot trial among Chinese Canadians. The recruitment was conducted in a community centre. Two recruitment approaches, self-referral and proactive recruitment, were used. Among 618 Chinese Canadians in the blood pressure screening, 105 (17.0%) individuals were eligible to participate in this trial. Of the 105 eligible individuals, 45 (42.9%) declined enrollment and 60 (57.1%) consented to participate in the trial and were recruited. The most common reason for refusal was being unable to access to the education location (n=19, 42.2%) followed by being too busy to participate (n=18, 40.0%). All participants were Chinese immigrants and the mean number of years living in Canada was 9.2. Most participants had low English proficiency, accepted Chinese culture more than Western culture, and had strong traditional health beliefs. It is concluded that both self-referral and proactive recruitment approaches were effective. Home-based interventions using Internet and telephone should be used as alternative delivery approaches to improve recruitment rate and facilitate participation.

Abstract
BACKGROUND There is a lack of culturally sensitive dietary interventions targeting Chinese Canadians despite unhealthy dietary behaviours being identified as the most important modifiable risk factor for hypertension in the Chinese population. AIMS To determine the feasibility of a culturally sensitive dietary intervention for hypertension control; to examine the potential effects of the intervention on blood pressure and health-related quality of life among Chinese Canadians in community. METHODS This study was a two-group pilot randomized controlled trial with 8 weeks follow up. Sixty self-identified Chinese Canadians, older than 45 years old and with grade one hypertension but not on antihypertensive medications were recruited in community. The control group received usual care and the intervention group received usual care plus newly developed DASHNa-CC intervention. The DASHNa-CC intervention consisted of a written manual, two classroom sessions, and one telephone booster call to provide healthy dietary and sodium reduction advice, integrated with Traditional Chinese Medicine food therapy recommendations for hypertension control. RESULTS 618 Chinese Canadians participated in blood pressure screening, and 60 eligible participants recruited. Participants were highly satisfied with the intervention and adhered to the trial protocol. The lost to follow-up rate was 5%. At 8 weeks post-randomization, those in the intervention group had greater reductions in systolic blood pressure [3.8mmHg, t (55) = -1.58, p = 0.12] and higher physical health scores [t (55) = 2.13, p = 0.04] compared to those of the control group. There were no group differences in health care utilization. CONCLUSIONS It is feasible to deliver the DASHNa-CC intervention in a Chinese Canadian community. The DASHNa-CC intervention may decrease blood pressure and improve health-related quality of life for Chinese Canadians.

Abstract
Responding to high prevalence of hypertension and patients' preference of integrating traditional Chinese medicine for blood pressure control, the Dietary Approach to Stop Hypertension With Sodium Reduction for Chinese Canadian (DASHNa-CC) intervention was newly designed as a culturally sensitive dietary educational intervention to facilitate middle-aged and senior Chinese Canadians' blood pressure control in community. The aim of this study was to report the hypertension prevalence rate according to the data from blood pressure screening events, to describe the characteristics of health service utilization among aged Chinese Canadians, and to report the evaluation of participant satisfaction to the DASHNa-CC intervention. This study was designed as a pilot randomized controlled trial with a sample size of 60. Among 618 Chinese Canadians participated in blood pressure screening events, 54.5% (n = 337) having various levels of hypertension. Across 2 months, 38 (63.3%) participants made a total of 47 visits to see their family physicians; 20 (33.3%) participants consulted their family members 224 times for lifestyle modifications and hypertension self-management. Various forms of Chinese media were frequently used as sources of health care information, and English media were rarely accessed. Participants highly satisfied with the contents, delivery approaches, and integration of traditional Chinese medicine in the intervention. Results indicated that middle-aged and senior Chinese Canadians have high hypertension prevalence and specific characteristics of health service utilization. It is important to implement interventions, which are culturally tailored, language appropriate, using proper technology and incorporating traditional Chinese medicine, in Chinese Canadian community for hypertension control.

Abstract
Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the “hot” and “cold” nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control. Based on a statistical analysis of antihypertensive foods recommended in 20 books on the application of food therapy for hypertension control, the 38 most frequently recommended are celery, tomato, banana, hawthorn, garlic, onion, seaweed, apple, corn, green beans, persimmon, laver, kiwi, watermelon, eggplant, carrots, mushroom, peanut, soy products, sea cucumber, buckwheat, garland chrysanthemum, spinach, honey, dairy products, vinegar, black fungus, jellyfish, green onion, shepherd's purse, soybean, potato, pear, winter melon, bitter melon, oat, pea, and tea. Food therapy emphasizes the therapeutic effects of food, considering its nature, taste, and function on human balanced health, which leads to optimal blood pressure control. Current literature suggests that food therapy is effective in blood pressure control and can be incorporated into blood pressure self-management in the Chinese population.

Abstract
OBJECTIVE Evidence from epidemiological studies suggested that shorter and longer duration of nocturnal sleeping may increase the risk of hypertension for older adults. Little is known about the duration of midday nap on the variability of blood pressure among older adults. In this study, we examined whether duration of habitual midday nap is associated with level of blood pressure or the risk of hypertension in a middle-aged and older Chinese population. METHODS A total of 27 009 participants (mean age 63.6 years) from Dongfeng-Tongji Cohort Study received baseline examination including physical examination and laboratory tests, and a face-to-face-interview including demographic information, disease history, and lifestyle. Participants were categorized into five groups according to nap duration, such as no napping, less than 30 min, 30∼60 min, 60∼90 min, and at least 90 min. A series of categorical logistic regression models was used to examine the odd ratios of nap duration with hypertension. RESULTS The level of SBP and DBP increased significantly with longer duration of habitual midday napping. Nappers with longer nap duration had considerably higher rate of hypertension. The longer duration of napping was related to higher blood pressure level and was associated with a higher risk of hypertension. After adjusting for possible confounders, the longer duration (>60 min) of napping was still associated with hypertension CONCLUSION : Our findings showed that the practice of longer afternoon nap is associated with a higher increased risk of hypertension, independent of several covariates. Further prospective researches are needed to examine the midday nap duration for development of hypertension.

Abstract
Hypertension is a global public health issue and a major cause of morbidity and mortality. Because of population growth and ageing, the number of people with uncontrolled hypertension rose from 600 million in 1980 to nearly 1 billion in 2008. Furthermore, the number of adults with hypertension in 2025 has also been predicted to increase by about 60% to a total of 1.56 billion. The prevalence of hypertension in most Asian countries has increased over the last 30 years and more dramatically in the last 10 years. Several factors contributed to such changes in Asia, but acculturation to Western lifestyle, modernisation and urbanisation are considered key contributing factors. There are some unique features in regards to cardiovascular risk in Asia. Specifically, Asian regions have disproportionately higher mortality and morbidity from stroke compared with Western countries. Furthermore, the relationship between blood pressure level and risk of stroke is stronger in Asia than in Western regions. Although evidence-based and qualified guidelines for hypertension diagnosis and management have been released recently from Europe and North America, the unique features of Asian patients with hypertension raise concerns in regards to the real clinical applicability of Western guidelines in Asian populations. Specifically, it is not yet clear to what extent the new blood pressure target proposed by Western guidelines for high risk and elderly hypertensive individuals apply to Asian populations.

Abstract
BACKGROUND The aim of this study was to evaluate the prevalence of cardiovascular autonomic (CA) dysfunction in the general Chinese population (instead of focusing on only patients with diabetes) and to develop a clinical risk model for the disease. METHODS AND MATERIALS We evaluated CA dysfunction prevalence in a dataset based on a population sample consisting of 2,092 individuals. Clinical risk models were derived from exploratory sets using multiple logistic regression analysis. The performance of the clinical risk models was tested in the validation sets. RESULTS CA dysfunction prevalence was 18.50% in the general Chinese population, while the prevalence was 24.14% in individuals aged ≥60 years. Its prevalence was 31.17, 24.69, and 21.26% in patients with diabetes, and hypertensive, and metabolic syndrome populations, respectively. Finally, we developed clinical risk models involving seven risk factors. The mean area under the receiver-operating curve was 0.758 (95% CI 0.724-0.793) for these models. The mean sensitivity and specificity of the clinical risk models was 75.0 and 66.2%, respectively. CONCLUSION CA dysfunction prevalence was high in the general Chinese population, and its prevalence was more frequent in individuals with diabetes, and hypertensive, and metabolic syndrome. Clinical risk models with a high value for predicting CA dysfunction were developed. CA dysfunction has become a major public health problem in China that requires strategies aimed at the prevention and treatment of the disease.

Abstract
BACKGROUND Several studies using acupuncture to treat essential hypertension have been carried out. However, whether acupuncture is efficacious for hypertension is still controversial. Therefore, this trial aims to evaluate the efficacy and safety of acupuncture for patients with mild hypertension. METHODS/DESIGN This is a large scale, open-label, multicenter, randomized controlled clinical trial with four parallel arms. We will recruit 428 hypertensive patients with systolic blood pressure (SBP) between 140 and 159 mmHg, diastolic blood pressure (DBP) between 90 and 99 mmHg. The participants will be randomly assigned to four different groups (three acupuncture groups and one waiting list group) (1).The affected meridian acupuncture group (n = 107) is treated with acupoints on the affected meridians (2).The non-affected meridian acupuncture group (n = 107) is treated with acupoints on the non-affected meridians (3).The invasive sham acupuncture group (n = 107) is provided with sham acupoints treatment (4).The waiting-list group (n = 107) is not offered any intervention until they complete the trial. Each patient allocated to acupuncture groups will receive 18 sessions of acupuncture treatment over 6 weeks. This trial will be conducted in 11 hospitals in China. The primary endpoint is the change in average 24-hSBP before and 6 weeks after randomization. The secondary endpoints are average SBP and average DBP during the daytime and night-time, and 36-Item Short Form Survey (SF-36), and so on. DISCUSSION This is the first large scale, multicenter, randomized, sham controlled trial of acupuncture for essential hypertension in China. It may clarify the efficacy of acupuncture as a treatment for mild hypertension. TRIAL REGISTRATION Clinicaltrials.gov Identifier: NCT01701726.

Chinese herbal medicine qi ju di huang wan for the treatment of essential hypertension: a systematic review of randomized controlled trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2013; 2013:262685. [PMID: 23878593 PMCID: PMC3708442 DOI: 10.1155/2013/262685] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/18/2013] [Revised: 04/25/2013] [Accepted: 05/12/2013] [Indexed: 12/29/2022]
Abstract
Background. Chinese herbs are potentially effective for hypertension. Qi Ju Di Huang Wan (QJDHW) is a commonly used Chinese herbal medicine as a monotherapy or in combination with other antihypertensive agents for the treatment of essential hypertension (EH). However, there is no critically appraised evidence such as systematic reviews or meta-analyses on the effectiveness and safety of QJDHW for EH. Methods and Findings. CENTRAL, PubMed, CBM, CNKI, VIP, and online clinical trial registry websites were searched for published and unpublished randomized controlled trials (RCTs) of QJDHW for essential hypertension up to January 2013 with no language restrictions. A total of 10 randomized trials involving 1024 patients were included. Meta-analysis showed that QJDHW combined with antihypertensive drugs was more effective in lowering blood pressure and improving TCM syndrome for the treatment of essential hypertension than antihypertensive drugs used alone. No trials reported severe adverse events related to QJDHW. Conclusions. Our review suggests that QJDHW combined with antihypertensive drugs might be an effective treatment for lowering blood pressure and improving symptoms in patients with essential hypertension. However, the finding should be interpreted with caution because of the poor methodological quality of included trials. There is an urgent need for well-designed, long-term studies to assess the effectiveness of QJDHW in the treatment of essential hypertension.
