18 years of age were enrolled. The blood pressure measurements at the wrist were compared with the results obtained by auscultatory measurement on left upper arm. Both measurements were taken 3 times in each person. A total 273 measurements were obtained in 91 participants. The evaluation of the accuracy was assessed by 2 statistical methods. (1)The differences between the 2 devices for a given measurement. (2) The differences between the 2 devices for a given person. Results Method 1 showed the sample mean errors and standard deviation of errors were 0.5?7.1 mm Hg for systolic blood pressure(SBP) and -1.6?6.1 mm Hg for diastolic blood pressure(DBP). Method 2 showed they were 0.5?6.1 mm Hg for SBP and -1.6?5.3 mm Hg for DBP. Blood pressure level and the wrist circumferences had no influence on the measurement errors. Conclusion The HEM-6000 wrist blood pressure device apparently met the AAMI criteria and is valid for patient self-measurement.

0.05). After treatment the incidence of ED in therapy group was decreased to 46.3% vs control group of 63.7%(P

Background FIZZ1 is a newly found protein associated with pulmonary inflammation. It has been shown to involve in proliferation of pulmonary arterial vascular smooth cells, contriction of vascular vessels, and stimulation of fibroblasts. Objective This study was designed to investigate the expression of FIZZ1 in atherosclerotic plaque of C57BL/6J ApoE-/-mice and the role of FIZZ1 on the proliferation of vascular smooth muscle cells obtained from aorta. Methods Nine C57BL/6J ApoE-/-mice were fed with high fat diet and nine C57BL/6J wild type mice with normal chow for 24 weeks. All mice were euthanized and the aortas were collected. HE stain histological examination and FIZZ1 immunohistochemistry were used in vivo study. In vitro, smooth muscle cells were treated with normal saline (control groups) or recombinate FIZZ1 at different concentrations (final concentration 3?10-6, 9?10-6, 2.7?10-5 mmol/L) respectively. The proliferation of smooth muscle cells were detected by MTT. Results After 24 weeks of high fat diet treatment, large atherosclerotic plaques were found in aortic root of ApoE-/-mice. FIZZ1 was found in atherosclerotic plaques of C57BL/6J ApoE-/-mice, however, no FIZZ1 was expressed in the arteries of C57BL/6J wild type mice. Cell culture study showed FIZZ1 promoted the proliferation of smooth muscle cells in a dose dependent manner(P

Objective The aim of this study was to evaluate the efficacy and safety of combination therapy with low-dose pravastatin and fenofibrate in patients with combined hyperlipidemia. Methods One hundred eighty nine patients with combined hyperlipidemia were randomly assigned to receive 10 mg pravastatin (n=64) or 200 mg fenofibrate (n=63), or a combination of 10 mg pravastatin and 200 mg fenofibrate (n=62) for 12 weeks. The patients in the monotherapy groups (n=35) whose lipid levels were not controlled after 12 weeks were randomly assigned to receive 20 mg pravastatin, or 200 mg fenofibrate, or a combination of 10 mg pravastatin and 200 mg fenofibrate for another 12 weeks. Lipid levels and adverse effects were assessed. Results After 12 weeks treatments, serum TC, LDL-C and TG levels were reduced and HDL-C was increased more significantly in combination therapy group, compared with 2 monotherapy groups (all P

Objective To investigate alexithymia , personality characteristic and mental condition in patients with essential hypertension. Methods Fifty-one patients with essential hypertension were assessed using Eysenck personality questionnaire (EPQ), Toronto alexithymia scale (TAS-20) and the symptom checklist-90 (SCL-90). The results were compared with those of Chinese ordinary model. Results The E score of EPQ of the patients with essential hypertension was lower than that of the Chinese ordinary model, while the N, P and L scores was higher. The total score and the scores of all factors of SCL-90 were significantly higher than that of Chinese ordinary model. The total score of TAS-20 and score of factor 1, factor 2 were positively correlated with the scores of all factors of SCL-90, while factor 3 score had no significant correlation with SCL-90. The E score of EPQ was negatively correlated with the scores of all factors of SCL-90, while N and P score were positively correlated with them. Conclusion Patients with essential hypertension were inner personality, unstable psychological status and neuroticism showing alexithymia and obvious psychological symptoms.

Objective To Evaluate the cognitive function in essential hypertensive patients complicated with metabolism diseases. Methods Eighty five essential hypertensive patients(EH)and other seventy four essential hypertensive patients complicated with metabolic disorder (EH+MD) were enrolled. Patients of EH+MD were categorized into glucose metabolism disorder (n=27), hyperlipidemia (n=15) and gluco-lipid metabolism disorder (n=22). Cognitive function was evaluated using "Clinical memory measuring scale" and "CISA intelligence scale". Results Direction and association memory, free imaging and portrait memory were better in EH than that in EH+MD (P

Objective To evaluate the significance of coronary calcification and stenosis in elderly hypertensive patients by 16-row multi-sliced computed tomography (MSCT) and its association with peripheral arterial atherosclerosis and other target organ damages. Methods Sixty-four patients with hypertension (n=50) 76.1?6.5 years and normotensions (n=14) 73.4?6.8 years were enrolled. All patients underwent coronary calcification scan by MSCT and the coronary calcification score(CCS) was calculated as AJ130 and Volume. Fourty-four patients in the hypertensive group were subjected to MSCT enhanced scan for evaluation of coronary stenosis. Intima media thickness (IMT), atherosclerotic and calcified plaques in carotid and femoral arteries and ankle-brachial index (ABI) carotid and femoral arteries were measured by echosonography and echocardiography; Fasting plasma blood glucose, blood lipid series, insulin, HOMA-IR, hsCRP and morning urine albumin were determined. Results (1) Both AJ130 and Volume of left anterior descending artery(LAD), left circumflex artery(LCX) and the total calcification score were higher in the hypertensive group than those in the control group (P

Objectives To compare the effects of losartan and atenolol on fibrinolytic system and plasma von willebrand factor (vWF) in patients with essential hypertension. Methods Sixty patients with mild to moderate essential hypertension were randomized to receive lostartan(50 mg/d, n=30) or atenolol(50 mg/d, n=30) for 8 weeks. If the goal blood pressure(

Objective To investigate the expression of angiotensin-converting enzyme 2(ACE2) protein and mRNA in kidney of different age spontaneously hypertensive rats(SHR) and the role of ACE2 in the development of hypertension. Methods Male SHR(n=30) were allocated to 5 groups by age: 1)one-month-old group(S1); 2)two-month-old group(S2); 3)three-month-old group(S3); 4)six-month-old group(S6); 5)nine-month-old group(S9). Sex and age matched Wistar-Kyoto normotensive rats(WKY)served as controls. The expression of ACE2 mRNA in kidney was determined by reverse transcription polymerase chain reaction(RT-PCR). The expression of ACE2 protein in kidney was assessed by immunohistochemistry and computer image analysis. Results 1)An age-dependent increase of SBP was observed in SHR before six months(P0.05). 2)An age-dependent increase of the ACE2 protein and mRNA levels in kidney was observed in both SHR and WKY(P0.05). The ACE2 protein and mRNA levels in kidney were lower in SHR than those in the matched WKY at every corresponding time point(P

Objective To study the effects of genistein(GST) on the expression of estrogen receptor ?(ER?) and the expression of c-fos gene in the aorta of ovariectomized rats.Methods Forty female Wistar rats were randomly divided into four groups:sham-operated(control),ovariectomized(OVX),ovariectomized with 17?-E2 replacement(OVX+E2),ovariectomized with genistein replacement(OVX+GST) group.After 8 weeks' replacement therapy,the rats were sacrificed and the expression of ER? and c-fos in the aorta was studied by immunohistochemistry.Results Ovariectomy significantly decreased ER ? expression and increased c-fos expression in aorta;while replacement therapy,GST and E2,attenuated the effect of ovariectomy manifested by increasing ER expression and decreasing c-fos expression in aorta.Conclusion GST may modulate the expression of ER? in the arteries of ovariectomized rats and play a beneficial effects on cardiovascular system which was associated with decreases in expression of c-fos gene in aorta.
