Association between serum allergens and asthma in children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the association between serum-specific immunoglobulin E (sIgE) allergens and asthma in children.</p><p><b>METHODS</b>The serum sIgE allergens were determined using Western blot in 2239 children aged 1-14 years, consisting of 1415 children with asthma alone and 824 children with non-allergic diseases between December 2004 and April 2013. The case-control models of asthma alone and non-allergic diseases were established. The association between allergens and asthma was investigated using multivariate logistic regression analysis.</p><p><b>RESULTS</b>In the 2239 children, 1028 children (45.91%) were serum sIgE-positive, and the allergen with the highest positive rate was house-dust mite (15.68%), followed by house dust (14.29%) and moulds (13.40%). The results of the case-control analysis showed that house-dust mite, moulds, house dust, and cashew nut/peanut/soybean were significantly associated with the development of asthma. House dust was associated with the development of asthma in the 1-2 years old group (P<0.05). House dust and house-dust mite as allergens were identified as the risk factors for the development of asthma in the 3-14 years old group (P<0.05). In the 6-14 years old group, moulds as allergens were identified as the risk factors for the development of asthma (P<0.05). House dust and house-dust mite as allergens increased the risk of asthma in boys and girls, while moulds and cashew nuts/peanuts/soybeans as allergens increased the risk of asthma in boys.</p><p><b>CONCLUSIONS</b>House-dust mite, house dust, and moulds are the most common allergens in children with asthma, and they are closely associated with the development of asthma.</p>

Prevalence of erectile dysfunction and it's related factors in type 2 diabetic patients / 中华全科医师杂志

Objective To investigate prevalence of erectile dysfunction(ED)in type 2 diabetic male patients and to analyze its related factors.Methods A total of 904 married male patients with type 2 diabetes were involved in this study and they were interviewed with anonymous questionnaire.An international index of erectile function-5(IIEF-5)was used to determine the severity of ED by self-rating score in age,duration of diabetes,serum level of glycosylated hemoglobin A1c(HbA1c),history of alcohol drinking and smoking,blood pressure and anti-hypertensive medication in diabetic ED patients.Relationship between relevant factors and diabetic ED was analyzed.Results ED was diagnosed in 612 diabetics with prevalence of 67.7 percent(612/904)according to their total scores of IIEF-5.Logistic regression analysis showed that increase in duration of diabetes by five years,age by 10 years,serum level of HbAI c by 2%, systolic blood pressure by 30 mm Hg(1 mm Hg = 0.133 kPa),positive history of smoking and alcohol drinking were all independently associated with prevalence of diabetic ED,with OR of 1.96,1.25,2.32, 1.12,1.67(P

Effects of losartan and amlodipine on plasma leptin and adiponectin levels and insulin sensitivity in obese hypertensive patients / 中华内分泌代谢杂志

Objective To observe the effects of losartan and amlodipine on blood pressure,plasma levels of leptin,adiponectin and norepinephrine (NE) and insulin sensitivity in obese hypertensive patients.Methods The levels of plasma leptin and adiponectin were determined by RIA and the plasma NE level was assayed by high- performance liquid chromatography.Insulin resistance index (HOMA-IR) was evaluated using the homeostasis model.Results Compared with basal levels,after 16-weeks' therapy,plasma leptin,HOMA-IR and body mass index were significantly decreased in losartan group [(35.6?18.5 vs 32.0?17.1)?g/L,P
