ABSTRACT
Objective@#To explore the correlation between obesity and first ejaculation in boys aged 11-18 years old in Ningxia in 2019, and to provide the theoretical reference for puberty development among obese boys.@*Methods@#Using the method of stratified random cluster sampling, 5 240 boys aged 11- 18 were selected from Yinchuan, Zhongwei, Wuzhong and Guyuan in Ningxia Hui Autonomous Region. Height, weight, and first ejaculation were obtained.Body mass index (BMI) was calculated to determine nutritional status, and the χ 2 test was used to compare the differences between groups of nutritional status; the probability unit regression method was used to calculater the soth percentile age at ejaculation, and the U test was applied to compare the differences in age at ejaculation between groups.@*Results@#The rates of overweight and obesity among boys aged 11 to 18 years in Ningxia Hui Autonomous Region in 2019 were 15.5% and 8.8%. The detection rate of overweight and obesity among urban boys was 17.8% and 10.5% and the detection rate of overweight and obesity among rural boys was 12.9% and 6.9%,respectively. The 50 th percentile age at half ejaculation among urban boys aged 11 to 18 years was 14.94 years; the 50 th percentile age at ejaculation among rural boys was 15.33 years( P <0.01). The 50 th percentile age at ejaculation was 15.61, 15.10, 15.05 and 15.05 years for boys in the wasted, normal weight, overweight and obese groups, respectively.@*Conclusion@#Nutritional status was not associated with age at first ejaculation in the present study,but warrants farther investigation.
ABSTRACT
Objective To analyze the changes of Tpeak-Tend interval (Tp-Te) in patients with type 2 diabetes mellitus (T2DM),and to explore the relationship between the changes of Tp-Te and ventricular arrhythmias. Methods A total of 112 patients with T2DM were selected from the Department of endocrinology of our hospital from June 2014 to May 2016 (T2DM group),and 65 subjects underwent healthy physical examination in our hospital were selected as the normal control group (NC group) during the same period.The general data,fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),Tp-Te,Tp-Te dispersion (Tp-Ted) were compared between the two groups.The changes of Tp-Te in patients with or without ventricular arrhythmia in T2DM group were also analyzed. Results The FPG,HbA1c,LDL-C,TC and heart rate were significantly higher in T2DM group than in the NC group (P<0.05).Compared with the control group,V5 lead Tp-Te and Tp-Ted in T2DM group was significantly prolonged (P<0.05).IN T2DM group,V5 lead Tp-Te and Tp-Ted were significantly longer in patients with ventricular arrhythmias than in patients without ventricular arrhythmia (P<0.05).Multiple logistic regression analysis showed that the increase of HbA1c and FPG were independent risk factors for prolonged Tp-Ted,and Tp-Ted was an independent risk factor for ventricular arrhythmia. Conclusion Patients with T2DM are more likely to have prolonged Tp-Ted.The prolonged Tp-Te and Tp-Ted could increase the incidence of ventricular arrhythmias.
ABSTRACT
Objective To diagnose the patients with coronary heart disease and arrhythmia by the ECG and dynamic ECG,in order to compare the clinical application value of two kinds of examination methods.Methods 120 patients with coronary heart disease were studied,and the dynamic electrocardiogram and routine electrocardiogram were given.The positive detection rate of two kinds of ECG examination method and the effect of clinical detection were observed and compared,.Results The positive detection rate of the dynamic electrocardiogram was 63.33%(76 /120),which was higher than 50.00% (60 /120)of conventional ECG,but the difference was not statistically significant (P >0.05).Pairs and atrial,ventricular contractility in front of the room,room sex period before contraction trigeminy and nonsustained ventricular rate dynamic electrocardiogram (ECG)the number of detected cases were 24 cases,42,54,52 cases,32 cases,which were significantly higher than those in routine ECG examination of the 12 cases,4 cases,20 cases,14 cases,4 cases of(χ2 =6.317,825.7,6.112,5.368,6.414,all P 0.05).Conclusion In the implementation of routine ECG in patients with coronary heart disease,The dynamic ECG can obtain a higher positive rate than ECG diagnosis,and has certain advantages in the detection effect,and has a certain clinical application value.
ABSTRACT
Objective: To observe the clinical effect of sodium nitroprusside and dopamine injected by micro pump for the treatment of refractory heart failure. Methods:One hundred and six cases of patients with refractory heart failure were chosen as the research object, which were cardiac functionⅢ~Ⅳlevel. All patients were treated with sodium nitroprusside and dopamine injected by micro pump. Starting dose of sodium nitroprusside was 6.25 μg/min. At same time pumping dopamine, starting dose of 2 g/kg·min, the dose was increased gradually until blood pressure dropped to 90~100 mm Hg, continuous 7~10 d, the signs and symptoms after treatment and parameters of cardiac function and adverse reactions were observed. Results: 1)In 106 cases of patients with refractory heart failure after treatment, the total effective rate 85.85%(91/106). 2)The heart rate, blood pressure, cardiothoracic ratio, left ventricular short axis reduced rate,cardiac output, each index of cardiac,indexes of left ventricular ejection fraction were improved significantly after treatment. Conclusion:The clinical effect for the treatment of refractory heart failure by using the micro pump injection of small doses of sodium nitroprusside combined dopamine would be obvious, have less adverse reactions, worthy of clinical popularization and application.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between expression of coiled-coil domain-containing protein 80(CCDC80) and obesity in serum and adipose tissues.</p><p><b>METHODS</b>A cross-sectional survey was conducted in a hospital in Tangshan in September 2010. 100 people including 78 healthy people and 22 with type-2 diabetes were recruited. Another 36 female patients with benign tumor of Obstetrics and Gynecology were also recruited. Demographic characteristics and serum samples were collected from all subjects, basic biochemical indicators were tested. All subjects were divided into 'Normal Weight' and 'Overweight and Obese' according to their BMI (BMI <24.0 kg/m(2); BMI≥24 kg/m(2)). Serum CCDC80 of the 100 subjects was detected by ELISA. Visceral and subcutaneous fat were derived from the other 36 female subjects, and Real-time PCR was used to detect CCDC80 mRNA expression in adipose tissues. Pearson correlation and multiple linear regression were used to analyze the correlation between serum or adipose CCDC80 expression and waist, BMI, and other biochemical indicators.</p><p><b>RESULTS</b>The age of 100 subjects was (52.9±8.4) years old. 44% of them were women (44 cases) and 56% of them were men (56 cases). After dividing them into three groups according to their BMI, covariance analysis were conducted, and age and gender were adjusted. The HDL-C level was significantly different among three groups (F = 10.73, P < 0.001): 'Overweight and obese combined with diabetes' group ((0.90±0.06) mmol/L)< 'Overweight and obese' group ((1.14±0.04) mmol/L) < 'Normal weight' group ((1.28±0.05) mmol/L). The adjusted expression of serum CCDC80 of the 100 subjects was (5.84±0.16) pg/ml, (5.81±0.98) pg/ml among men and (5.97±0.89) pg/ml among women, and there was no significant difference (t = -0.812, P = 0.419) between genders. ANOVA revealed that there was no significant differences of the expression of serum CCDC80 among three groups (F = 1.06, P = 0.351), 'Normal weight' group was (5.84±0.16) pg/ml, 'overweight and obese' group was (6.11±0.14) pg/ml, and 'Overweight and obese combined with diabetes' group was (5.84±0.19) pg/ml. The analysis showed that FBG had a negative correlation with serum CCDC80 (R(b) = -0.223, P = 0.026). Multivariate linear regression had a similar result, with 1 mmol/L increase of serum FBG, serum CCDC80 decreases for 0.24 pg/ml (β = -0.24, 95% CI: -0.21--0.02). There was also a negative correlation between serum CCDC80 and FBG in overweight and obese people (R(a) = -0.368, P = 0.013). Besides, CCDC80 mRNA was detected in both subcutaneous and visceral adipose tissue of 36 cases, the expression level was 0.06±0.02 for subcutaneous fat, was 0.05±0.04 for visceral fat, and the expression in visceral fat was lower (0.05±0.03) than that in subcutaneous fat (0.06±0.03) (t = 2.50, P = 0.025) among overweight and obese group. There was a negative correlation between waist and visceral CCDC80 mRNA expression (r = -0.472, P = 0.035).</p><p><b>CONCLUSION</b>This study suggested that CCDC80 may be involved in energy and insulin metabolism, and plays a protective role in obesity and diabetes.</p>
