Objectives: To evaluate the clinical implication of notch (N) Wave in ECG for patients with left circumflex artery-related acute myocardial infarction. Methods: A total of 416 patients with left circumflex artery-related acute myocardial infarction hospitalized in our hospital from January 2013 to December 2016 were included in this study. According to the electrocardiogram, 156 people were divided into ST segment elevation myocardial infarction group, 108 patients in N wave non-ST segment elevation myocardial infarction group, and 152 patients in non-N wave NSTEMI group. Troponin I and creatine kinase isoenzyme, hospitalization to operation time, vascular lesion site and degree, the intraoperative and postoperative complications were compared among the 3 groups. Results: Troponin I and creatine kinase isoenzyme levels were significantly lower in non-N wave NSTEMI group than in STEMI group and N wave NSTEMI group (P<0.05). The occurrence rate of no-reflow phenomenon was significantly higher in N wave NSTEMI group than in STEMI group and non N wave NSTEMI group (P<0.05). There was no significant difference in incidence of cardiac shock, ventricular fibrillation, ventricular aneurysm and death rate among the 3 groups(P>0.05). Incidence rate of lesion located in the proximal and middle section of left circumflex artery as well as the mean vascular stenosis degree were significantly lower, while incidence rate of lesion located in the distal section of left circumflex artery and obtuse marginal branches was significantly higher in non N wave NSTEMI group than in STEMI group and N wave NSTEMI group(P<0.05). Conclusions: Presence of Notch wave in ECG is associated with higher incidence of lesion located in the proximal and middle section of left circumflex artery, larger infarct size and higher incidence of no-reflow in patients with left circumflex artery-related acute myocardial infarction.

<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of combination administration of hydrochlorothiazide and nitrendipine at low dosage in the treatment of rural hypertension patients.</p><p><b>METHODS</b>By the method of cluster random sampling, 5292 primary hypertension patients from Fuxin, Liaoning Province were divided into health education group (control group) and drug intervention group in June 2006. The drug intervention group were treated with hydrochlorothiazide, nitrendipine and captopril by stepwise approach and we observe the antihypertensive effect of drug and the effect on the onset of stroke.</p><p><b>RESULTS</b>The average follow-up time was 15 months. At last, 308 patients were lost to follow-up (the lost follow-up rate was 5.8 percent). The 4984 in cohort, including 2530 of intervention group and 2454 of control group, had examination of all indicators. Through health education and drug intervention, the average blood pressure in drug intervention group decreased by 16.1/9.4 mm Hg (1 mm Hg = 0.133 kPa) while the average blood pressure in control group decreased by 6.7/3.5 mm Hg. The control rate of blood pressure in drug intervention group was higher than control group (33.1% vs. 15.1%, P < 0.001). Through drug intervention, the morbidity risk of nonfatal stroke in drug intervention group decreased by 57.3% compared to control group, the total morbidity risk of stroke decreased by 59.4%. The results had significant statistical difference. And, the morbidity of severe hypopotassaemia (K(+) < 3.0 mmol/L) and diabetes mellitus had no significant statistical difference between two groups.</p><p><b>CONCLUSIONS</b>The low-cost antihypertensive program based on thiazide had good antihypertensive effect, high safety and good cost-effect ratio. The program could be used in rural areas of China.</p>

<p><b>OBJECTIVE</b>This study observed the association between body mass index (BMI), waist circumference (WC) and blood pressure level in rural residents from west Liaoning province.</p><p><b>METHODS</b>This epidemiological study using stratified cluster random sampling was conducted from 2004 to 2006 in Fuxin County, Liaoning Province, 43,692 rural residents (21,680 males) aged 35-74 years old [(49. 8 +/-10.2) years] were surveyed. Database was established with the help of Epidata 3.1 software.</p><p><b>RESULTS</b>In total 43,692 persons were surveyed, including 21,680 male (49.6%) and 22,012 female (50.4%). The average BMI and WC was (23.31 +/- 3.08) kg/m2 and (80.87 +/- 9.0) cm, respectively. No matter male or female, SBP started from 20 kg/m2, increased with the increase of BMI; DBP increased gradually with the increase of BMI; the prevalence of hypertension were significant differences among different BMI groups (P < 0.001). Multiple logistic regression show that in male, using the group with BMI, <18 kg/m2 as control, 28-30 kg/m2 group OR and 95% CI was 6.285 (4.612-8.566); in female, when BMI >22 kg/ m2 OR increased with the increasing of BMI. In male and female, both SBP and DBP, also the prevalence rate of hypertension increased gradually with the increase of WC (P < 0.001). No matter in male or female, when BMI <24 kg/m2, and WC male <85 cm, female WC <80 cm, the average blood pressure levels and prevalence of hypertension are the lowest; after adjusting for age and other risk factors, the prevalence rate of overweight and obesity for male with hypertension OR are 1.704 (1.592-1.825) and 3.710 (3.148 -4.371) , respectively, for female is 1.527 (1.428-1.632) and 3.014 (2.668-3.405), respectively. When the WC is higher than the standard, male and female hypertension risk OR and 95% CI are 1.231 (1.153-1.314) and 1.353 (1.269-1.442), respectively.</p><p><b>CONCLUSION</b>Both BMI and WC are risk factors of hypertension.</p>

Through cluster multistage sampling,a resident group of 6 412 subjects with hypertension in the rural area of Liaoning province were recruited.According to IDF and NCEP-ATPm criteria the age-standardized prevalences of metabolic syndrome were 36.2%and 25.9%respectively.The prevalence of metabolic syndrome decreased with advancing age,but increased with rising of blood pressure.
