BMI, Blood Pressure, and Plasma Lipids among Centenarians and Their Offspring.

BACKGROUND: The burden of cardiovascular diseases (CVDs) is increasing substantially due to population growth and aging. Determining effective prevention and understanding the underlying mechanisms remain desirable pursuits for increasing the quality of life. As centenarians and their offspring may have genetic advantages, they may present with healthier cardiovascular-related profiles. METHODS: We launched a cross-sectional household-based survey of centenarian families, including 253 centenarians, 217 centenarian offspring, and 116 offspring spouses without centenarian parents from county-level Chinese longevity city Rugao. Among offspring and offspring spouses were the following arrangements: 101 paired offspring and offspring spouses who lived together, 116 unpaired offspring, and 16 unpaired spouses. We investigated their cardiovascular-related health status including waist circumference, body mass index (BMI), blood pressure, and plasma lipids and compared results among centenarians, centenarian offspring, and offspring spouses. RESULTS: Centenarians ranged from 99 to 109 years with a median age of 100 years. Centenarian offspring, with a median age of 70 years, and offspring spouses, with a median age of 69 years, shared similar age. Results of blood pressure, plasma lipid levels, and BMI displayed no significant difference between centenarian offspring and offspring spouses. However, centenarians appeared to have lower waist circumference, BMI, TC, LDL-C, TG, and diastolic blood pressure but higher levels of systolic blood pressure (p < 0.05). Multivariate analysis showed the prevalence of obesity, hypertension, and dyslipidemia was similar between centenarian offspring and offspring spouses, while centenarians appeared to have a lower prevalence of obesity and a higher prevalence of hypertension (p < 0.05). CONCLUSIONS: Centenarians and centenarian offspring did not present healthier BMI, blood pressure, or plasma lipids than offspring spouses. Further research on longevity and cardiovascular diseases are desirable.

Shuxuetong for Prevention of recurrence in Acute Cerebrovascular events with Embolism (SPACE) trial: rationale and design.

BACKGROUNDS: Embolic stroke is one of the main mechanisms of ischaemic stroke. Even if treated with recommended antithrombotic agents, stroke recurrence remains high. The Shuxuetong injection, a purified extract of traditional Chinese medicine widely used for thrombus diseases in clinical practice in China, could be a promising agent to prevent stroke recurrence. AIMS: To describe the design of the Shuxuetong injection for prevention of recurrence in acute ischaemic stroke with embolism mechanisms. DESIGN: The Shuxuetong for Prevention of recurrence in Acute Cerebrovascular events with Embolism (SPACE) trial is a multicentre, randomised, double-blind, placebo-controlled, parallel-group, superiority trial to evaluate the efficacy and safety of Shuxuetong injection in reducing recurrence or silent new ischaemic lesions on patients with acute embolic stroke within 10 days. An estimated 2416 patients with embolic stroke within 72 hours of symptom onset from 80 hospitals will be randomly assigned to one of two groups receiving Shuxuetong injection or placebo injection for 10 days. The primary endpoint is symptomatic or asymptomatic new cerebral infarction within 10 days after randomisation. CONCLUSION: The SPACE Trial will provide valuable evidence for the efficacy and safety of Shuxuetong injection for the prevention of stroke recurrence in patients with imaging-defined embolic stroke. CLINICAL TRIAL REGISTRATION: NCT03090113.

Age differences in clinical characteristics, health care, and outcomes after ischemic stroke in China.

BACKGROUND AND PURPOSE: Little information is available on the effects of age on health care and outcomes of ischemic stroke (IS) in China. Our aim was to evaluated risk factors, health care, and outcomes among age groups including ≤ 45, 46-65, 66-79, and ≥ 80 years and to find whether the outcome was affected by age and health care. METHODS: CNSR is a nationwide prospective registry for patients admitted with acute stroke and prospectively followed up 12-month outcomes. Demographics, socioeconomics, risk factors, health care, and outcomes were analyzed among age groups, and multivariate regression analysis was used to determine the association of outcome and age and health care. RESULTS: We identified 12,415 acute IS patients for analysis. Of 1179 (9.50%) were aged ≥ 80 years. In terms of risk factors, cardiac diseases were significantly more frequent in patients ≥ 80 years, behavioral risk factors were more common in younger patients, and hypertension, hyperlipidemia, and diabetes were more seen in 46-79 patients. The use of health care varied among groups and was significantly lower in ≥ 80 years especially in secondary prevention. The very old patients had the worst outcomes even after adjusting by prognostic factors; however, adjusting forward by health care, the extent of differences decreased. CONCLUSIONS: In CNSR, differences in stroke clinic characteristics and health care were observed among various age groups, and the old patients, receiving lower levels of stroke care, had the worst outcomes. Knowledge of the age differences in ischemic stroke may be helpful to appropriately allocate the limited health resources and to improve stroke outcomes.

Antithrombotic management of ischaemic stroke and transient ischaemic attack in China: a consecutive cross-sectional survey.

1. Little is known about the prevention of secondary stroke in China. In the present study, we assessed the status of antithrombotic management of stroke patients in clinics across China. 2. A cross-sectional survey was conducted in 19 urban neurological clinics. All subjects diagnosed with ischaemic stroke (IS) or transient ischaemic attack (TIA) were enrolled consecutively in the study. Face-to-face interviews were conducted by research assistants using questionnaires on the day of enrollment. The data recorded included demographic and clinical characteristics, medication and reasons for not using medication. Independent predictors for the prescription of antiplatelet drugs were determined using multivariate logistic regression models. 3. Of the 2283 patients with IS or TIA enrolled in the study (34.7% women; mean ( +/- SD) age 65.8 +/- 11.6 years), 1719 (75.3%) had a prescription for antiplatelet therapy. Of the 108 patients with atrial fibrillation, only 14 (13.0%) were receiving warfarin therapy. The main independent factors significantly associated with being on antiplatelet therapy were having basic health insurance (odds ratio (OR) 1.47; 95% confidence interval (CI) 1.09-1.99), government insurance and labour insurance (OR 1.63; 95% CI 1.03-2.59) and a monthly income of > 500 yuan (US$66.70; OR 2.14; 95% CI 1.51-3.03). Being older (OR 0.70; 95% CI 0.50-0.99) and having a severe disability (OR 0.68; 95% CI 0.49-0.97) were associated with lower odds of receiving antiplatelet therapy. 4. Based on the survey results, adherence to guidelines for antithrombotic management in neurological clinics in China is poor. The main reasons contributing to the less than optimal management of stroke patients include negative attitudes among neurologists, a lack of medical insurance, a lower income and being elderly and/or severely disabled.

[Effects of soybean isoflavone on born metabolism and morphology in animal model of osteoporosis rats].

OBJECTIVE: To study the effects of soybean isoflavone (SI) on born metabolism and morphology in animal model of osteoporosis rats. METHODS: All 70 female Sprague-Dawley (SD) rats were randomly divided into 7 groups according to the levels of total cholesterol (TC) in serum: hyper-lipoid group, estrogen group, low-dose SI group, middle-dose SI group, high-dose SI group, sham group and normal control groups. Bilateral ovaries were extirpated except sham and normal control groups. Except the rats in normal control group, the other rats were fed with high fat diet. Body weight was weighted ad unam vice per week. The estrogen, different dose of SI or deionized water were fed with intragastric administration for 12 weeks. Vena caudalis serum were collected after being ovariectomized, administered for 4 w, 8 w and killed. Serum alkaline phosphatase (AKP) activity and bone density were measured etc. RESULTS: To interfere of estrogen and SI might recover AKP enzyme activity after its being ovariectomized. There almost sowed no differences between high dose SI intervention and estrogen on bone density and microstructure. Bone loss due to being ovariectomized was relieved after SI intervention. SI might protect cardiocyte myofilament and mitochondrial ultramicrostructure. There was mirror image in estrogen, high dose SI group resembling the normal control group, and there was obvious damage in hyper-lipoids group. CONCLUSION: There should be effects of high dose SI on bone metabolism and morphology in animal model of osteoporosis rats. Serum AKP enzyme activity and bone density should have significantly recovered, the serum level of calcium and phosphorus were maintained after high dose intervened but no significant effects for low dose of SI.
