Objective To investigate the value of N-termind pro-B-type natriuretic peptide(NT-pro-BNP)in differential diagnosis of dyspnea in emergency department, and to investigate the rapid diagnosis cutoff of dyspnea due to acute congestive heart failure. Methods Ninety. one cases of dyspnea in emergency department recruited from January to June ,2008 were divided into two groups: acute cardiac dyspnea group and none acute cardiac dyspnea group. To evaluate the value of different parameters in differential diagnosis of dyspnea in emergency department and analysis the area under the receiver-operating characteristic of different parameters for the diagnosis of acute cardiac dyspnea. To achieve the best cutoff of different parameters for the diagnosis of dyspnea due to acute congestive heart failure finally. Results Among two groups, NT-pro-BNP (acute cardiac dyspnea vs. none acute cardiac dyspnea,6203.50 ng/L vs. 1410.00 ng/L,P ＜ 0.01), Troponin Ⅰ (acute cardiac dyspnea vs. none acute cardiac dyspnea,0.12 μg/L vs. 0.03 μg/L,P ＜0.01) ,left ventricular ejection fraction(acute cardiac dyspnea vs. none acute cardiac dyspnea,46.25% vs. 65.60%, P ＜ 0.01), left atrial diameter (acute cardiac dyspnea vs. none acute cardiac dyspnea,42.75 mm vs. 36.00 mm,P ＜0.01) had significant difference. NT-pro-BNP at cutoff of ≥3715 ng/L was highly sensitive and specific for the diagnosis of acute cardiac dyspnea. Receiver-operating characteristic analyses demonstrated that NT-pro-BNP and left ventricular ejection fraction was the best diagnostic indices of acute cardiac dyspnea. The area under the receiver-operating characteristic curve of Nt-pro-BNP was 0.828 ± 0.045 (P ＜ 0.01),and left ventricular ejection fraction was 0.829 ± 0.049 (P ＜ 0.01). Correlation analysis showed that NT-pro-BNP was correlated with left ventricular ejection fraction (P ＜ 0.01). The combined test of NT-pro-BNP and left ventricular ejection fraction was performed. Specificity increased to 96.50%, total consistent rate increased to 83.50% ,positive predictive value increased to 91.30%, positive likelihood ratio 17.60, faulse diagnostic rate decreased to 3.50%. Conclusions NT-pro-BNP examination in emergency department was helpful to rapid differential diagnosis of dyspnea. It helped to differentiate the patients with acute congestive heart failure and none acute congestive heart failure causes of dyspnea.

Objective To investigate the prevalence of dermatoses affecting officers and soldiers garrisoned southeast China,and to provide enough scientific basis for prevention and treatment of those dermatoses.Methods Epidemiological investigations were carried out on 324 officers and soldiers in both Zhejiang and Fujian military Regions,respectively.In order to get the dermatoses diagnosed correctly and the number of infected men/times calculated accurately,a large scale of clinical examination was performed by 3 senior dermatologists from the authors' hospital.Some medication and management were applied in therapy for those skin disorders.The elementary medical personnel in the troops were trained with a short time-training course to raise their vocational level.Results Tinea manuum and tinea pedis,acne,pigmented nevus,tinea corporis and tinea cruris,seborrheic dermatitis,eczema,pityriasis versicolor and lichen simplex chronicus were the eight common dermatoses affecting officers and soldiers garrisoned southeast China.The prevalence of tinea manuum and tinea pedis was highest one in all the 8 common dermatoses.158 out of 324 soldiers(48.8%)suffered from skin disorder.The prevalence of acne,pigmented nevus,tinea corporis and tinea cruris,seborrheic dermatitis,eczema,pityriasis versicolor and lichen simplex chronicus were 45.4%,19.3%,10.8%,12.3%,10.2%,7.4% and 7.1%,respectively.Conclusions Skin disorder is one of the most common diseases affecting officers and soldiers.There are different occurrences in different garrisoned region.The prevelence of tinea manuum and tinea pedis in Fujian military region is higher than that in Zhejiang military region,and the prevelence of tinea corporis and tinea cruris,eczema in Fujian military region is lower than that in Zhejiang military region.No significant difference was found in the prevalence of the eight common dermatoses between the two parts of soldiers originated separately from north or south regions of China.
