Objectives To compare the safety and efficacy of radial artery access versus femoral artery access for percutaneous coronary intervention in acute myocardial infarction population. Methods From June 2004 to December 2006, 446 patients with acute myocardial infarction treated with percutaneous stenting were reviewed retrospectively. The radial artery approach was used in 242 patients, and the femoral artery approach in 204 patients. The success of the procedure, procedure duration, X-ray exposition, volume of contrast, incidence of major adverse cardiac events and complications were compared between the radial artery and femoral artery approach. Results Total procedure duration, X-ray exposition, the immediate success of the procedure and the proportion of patients with reperfusion time above 60min are higher in patients with radial artery acess than that with femoral artery access [(62. 1 ± 23. 4) min vs(56. 8 ± 16. 7)min,(2829. 4 ± 1365.2) mGY vs (2352. 3 ± 903.1) mGY, 4% vs 0.9% and 7.44% vs 2.94%respectively, all P ＜ 0. 05]. Conclusions In non-selected patients with acute myocardial infarction treated with primary stent implantation, the success rate of the radial artery approach is lower than the femoral artery approach and could prolong the reperfusion time. It is suitable to change artery access immediately if abnormality is found via radial artery access.

Objective To investigate the prevalence,awareness,control status and associated risk factors of hypertension in a rural population in Xianghe county in North China.Methods A total of 830 adults (aged≥35) from Xianghe county were examined during July to August,2011.Blood pressure was obtained using a standardized sphygmomanometer after a 5-minute sitting rest.Information on gender,age,education level,marital status,smoking,drinking,income,family history of hypertension and use of antihypertensive medications was obtained.Results A total of 42.4％ of all subjects had hypertension.Among those with hypertension,the awareness rate was 54.8％ and 50.0％ of the patients were taking antihypertension medication with the control rate of 11.9％ [BP ＜ 140/90 mm Hg (1 mm Hg =0.133 kPa)].Lower age and education level,lower body mass index,negative family history of hypertension were associated with poor awareness of hypertension and worse compliance with the treatment.Older age,positive family history and alcohol consumption were associated with poor blood pressure control.Conclusions Hypertension is highly prevalent in Xianghe rural area.The awareness,treatment and control rate are all low.There is an urgent need for comprehensive strategies to improve prevention,screening,and treatment of hypertension in rural China.

Objective To investigate the effects of Hedan tablet on serum adipocytokines and inflammatory factors in rats with metabolic syndrome.Methods The 24-rat model of metabolic syndrome were randomly divided into three groups(n=8,each):normal group were given normal diet,model group were given high-lipid and high-salt diet and intervention group were given high lipid and high salt dict plus Hedan tablet 6.0 g · kg-1 · d-1 by intragastric administration for 3 weeks.Body weight,blood pressure,blood levels of glucose,lipid,leptin,visfatin,adiponectin and CRP were measured in all rats at the beginning and the end of the study.Results Compared with normal group,model group (model versus normal) showed significantly increased serum levels (P ＜ 0.05) of weight,total cholesterol(TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),glucose,leptin(5.5±0.1 vs.5.2±0.0 mmol/L),visfatin(17.5±0.5 vs.16.6±0.0 mmol/L and CRP(1 676.6 ± 74.8 vs.1 642.3 ± 52.2 mmol/L),and showed significantly decreased (P ＜ 0.05) serum level of adiponectin(74.6±2.4 vs.81.3±2.1 mmol/L).Compared with 20 weeks of age group,the 23 weeks of age group(23 weeks versus 20 weeks)showed significantly decreased levels of weight,TC,TG,LDL-C,serum leptin(5.4±0.1 mmol/L vs.5.9±0.2 mmol/L),visfatin(16.7±0.4 mmol/L vs.17.7±0.6 mmol/L)and CRP(1 498.8±51.0 mmol/L vs.1 682.1±76.6 mmol/L(all P＜0.05),and showed significantly increased serum adiponectin level(81.2±3.0 mmol/L vs.73.9±3.1 mmol/L)(P＜0.05).But there was no significant change in model group between 20 weeks and 23 weeks of age.Conclusions Hedan tablet reduces the body weight and ameliorates blood lipid level in rats with metabolic syndrome.These effects may be related to regulation of Hedan tablet on adipocytokines and inflammatory factors.

Objective To evaluate the abstinence rate and relapse rate of smoker with ACS after discharged from hospital, to evaluate the effect of simple smoking cessation interventions.Methods 150 smokers with ACS were collected and was divided into simple intervention group ( n = 87) and control group (n = 63) , respectively, followed up for 6 months.2 months, 6 months abstinence rate, relapse rate were compared between two groups, logistic regression model was used to analyzed the relevant factors for relapse.Results The smoking rate in patients with ACS was 31.14% , 6-month continuous abstinence rate and 6-month relapse rate was 64.6% , 36.4% , respectively.6-month continuous abstinence rate and relapse rate between simple quit-smoking intervention group and control group showed no difference.Nicotine dependence score more than 4 points can be used as predictor of relapse.Conclusions The smoking rate and the abstinence rate of smoker with ACS is higher than the general population, simple quit-smoking intervention do not increase the success rate of quit-smoking, indicated the need to strengthen the intervention in patients with ACS and smoking.

Objective This study was aimed to investigate the relationship between serum leptin,adiponectin,visfatin levels and obesity and essential hypertension in female subjects.Methods According to BMI and blood pressure,206 female participants enrolled were divided into four groups:group 1:obesity and hypertension (48 cases);group 2:non-obesity but hypertension (48 cases);group 3:obesity and normotension (56 cases) and group 4:normal BMI and blood pressure (54 cases).Serum leptin,adiponectin and visfatin levels were detected and their relationships to BMI,blood pressure and waist circumference were analysed.Results Serum leptin levels were significantly higher in non-obese groups [group 2:(4.47 ±1.26) ng/L,group 4:(3.73-±1.18)ng/L] than in obese groups [group 1:(2.97 ± 1.46) ng/L,group 3:(3.02 ± 1.18) ng/L],and higher in hypertension groups than in normotension groups.Serum adiponectin levels were obviously higher in group 4 [38.99 (19.75,103.71) μg/L] than in the other three groups.There were no significant differences in adiponectin levels among group 1,2 and 3.Serum levels of visfatin were lower in normotension groups [group 3:3.19 (0.96,9.45) ng/L;group 4:3.23 (1.92,4.64) ng/L] than in hypertension groups [group 1:3.84 (3.40,5.35) ng/L;group 2:3.75 (1.63,6.67) ng/L] irrespective of obesity.Logistics regression analysis showed that there was 1.6％,8.3％,or 5.45％ increased risk for hypertension for each 1 μg/L decrease in adiponectin,1 cm increase in waist circumference,or 1 μg/L increase in visfatin level in obesity,respectively.No relationship could be viewed between leptin and hypertension.Conclusions Adiponectin and visfatin levels were correlated with obesity and blood pressure in females.Both adipokines may play a crucial role in the development of hypertension in female obesity.

[ABSTRACT]OBJECTIVETo study the expressions of 34βE12, Galectin-3 and HBME-1 in thyroid nodules, and to explore its diagnostic value for papillary thyroid carcinoma (PTC).METHODSEn VisionTM immunohistochemical technique was used to detect the expression of 34βE12, Galectin-3 and HBME-1 in 352 thyroid lesions. The correlation between the expressions of the 3 protein markers and clinicopathological characteristics was evaluated. The receiver operating characteristic area under the curve (ROC-AUC) and their index for diagnosis evaluation were also calculated.RESULTSThe positive rates of 34βE12, Galectin-3 and HBME-1 in 246 PTC lesions were significantly higher than those in benign nodules (P<0.001). There was no relationship between the expression of the 3 protein markers and clinicopathological characteristics (eg. gender, age, numbers of lesions, tumor size, capsular invasion, lymph node metastasis, TNM staging). The ROC-AUC of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 0.936, 0.915 and 0.898 respectively. The sensitivity of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 94.3%, 95.5% and 91.1% respectively, while the specificity was 81.1%, 71.7% and 83.0% respectively, and the diagnostic accuracy rate was 90.3%, 88.4% and 88.6% respectively.CONCLUSION The expressions of 34βE12, Galectin-3 and HBME-1 are statistically different between PTC and benign lesions, but no associations are found with clinicopathological characteristics, indicating the three protein markers have important diagnostic value for PTC.

Objective To evaluate the effect of pitavastatin on blood glucose in patients with hypercholesterolemia,and to investigate the efficacy of pitavastatin in diabetic patients combined with hypercholesterolemia.Method This study was a 12-week,multi-center,open-label,without parallel-group comparison,phase Ⅳ clinical trail.Results Contrasting to baseline,the prevalences at week 4 and 12 post-treatment of abnormal fasting plasma glucose (FPG) and glycosylated hemoglobin Alc (HbA1c)( FPG:14.2％ vs 14.1％ and 11.0％ ; HbA1c:14.3％ vs 15.1％ and 16.1％ ) in the safety set subjects without diabetes mellitus (DM),as well as in those with DM but not taking glucose-lowering drugs (FPG:7/7 vs 4/7 and 5/7; HbAlc:5/5 vs 4/4 and 5/5) had no significant changes (all P vaules ＞0.05).Contrasting to baseline,the levels of TC [ (6.51±0.94) mmol/L vs (5.12 ±0.93) mmol/L and (4.54 ±1.00) mmol/L],LDL-C [(4.11 ±0.79)mmol/L vs (3.02 ±0.81) mmol/L and (2.51 ±0.70)mmol/L] and TG [2.10(1.53,2.54) mmol/L vs 1.62(1.26,2.00) mmol/L and 1.35(1.10,1.86)mmol/L]at week 4 and 12 post-treatment in the per protocol set 55 subjects with DM were significantly reduced (all P values ＜ 0.05 ) ; 33.3％ of subjects at high risk and 10.0％ of subjects at very high risk had achieved a TC target value; 55.6％ of subjects at high risk and 40.0％ of subjects at very high risk had achieved a LDL-C target value.Conclusion Pitavastatin has a safe effect on blood glucose and it could be used to treat diabetic patients combined with hypercholesterolemia in China.

Objective:To investigate the current situation of insomnia in patients with acute coronary syndrome (ACS), and analyze the influencing factors of insomnia in the ACS patients, so as to provide information on the development of new strategies for the treatment of insomnia in ACS patients.Methods:This is a multicenter and prospective observational study. A total of 771 ACS patients who met the criteria were selected from March 2013 to June 2015. The baseline social demographic information, sleep quality questionnaire, general anxiety disorder scale-7(GAD-7),patient health questionnaire-9(PHQ-9), short-form 12 health survey questionnaire(SF-12), and enhancing recovery in coronary heart disease patients social inventory(ESSI) were completed within 7 days after admission. Logistic regression analyses were used to analyze the influencing factors of insomnia in ACS patients.Results:A total of 741 subjects with valid questionnaires were collected, including 510 males (68.8%) and 231 females (31.2%). Among them, 487 (65.7%) subjects had at least one insomnia symptom: 308 (41.6%) subjects had difficulty in falling asleep, 369 (49.8%) subjects were easy to wake at night, 116 (15.7%) subjects woke up earlier than they expected, 74 (10.0%) subjects experienced both woke up earlier and difficulty in falling asleep, and 53 (7.2%) subjects woke up earlier, woke up at night and had difficulty in falling asleep at the same time. Logistic regression analyses showed that before admission physical activity ( OR =0.636, 95% CI 0.411-0.984), depression ( OR=1.908, 95% CI 1.101-3.305) and low social support ( OR=0.278, 95% CI 1.198-3.301) were independent factors of insomnia in ACS patients. Conclusions:Nearly 2/3 ACS patients have symptoms of insomnia. Difficulty in falling asleep and easy to wake up at night are the most common manifestations. Physical activity, depression and social support independently are associated with insomnia.
