Objective To evaluate the image quality and noise using different levels of the 4th iterative reconstruc-tion technique iDose4 in Coronary Computed Tomography Angiography (CCTA),and to explore the best level which can provide the best image quality and the low noise.Methods The Philips,Ingenuity Core 128 CT scanner was used to perform CCTA examination on 60 patients.The original data of every case were reconstructed using traditional filtered back projection (FBP)and seven different levels of iDose4 (iDose4-1 - iDose4-7),respectively.Image quality was as-sessed using 4-grade scale in consensus of two experienced doctors,and signal-and contrast-to-noise(SNR and CNR) ware quantified.Results SNR and CNR values of seven different levels iDose4 images were higher than those of FBP. There was positive linear correlation between SNR,CNR and iterative reconstruction.The image quality was no signifi-cant difference between iDose4-3 and iDose4-4,but iDose4-4 had the best SNR values,CNR values and low noise.Con-clusion At the same scanning conditions,compared with FBP,the application of iDose4 can significantly improve image quality and reduce image noise.Under the condition of this study,using iDose4-4 can get the best image quality.

Objective:To investigate the pulmonary tuberculosis patients complicated with diabetes treatment. Methods:selected clinical since 2009 were pulmonary tuberculosis patients complicated with diabetes 60 cases clinical treatment analysis. Results:in 60 cases, good blood glucose control or better tuberculosis lesions absorption, void closure, the sputum negative conversion rate increased. Conclusions: adhere to the two diseases treated at the same time, in the regular anti-tuberculosis treatment at the same time, aggressive treatment of diabetes, glycemic control, so that the two diseases are effective in the treatment of.

自发性气胸是指肺组织及脏层胸膜的自发破裂,或靠近肺表面的肺大疱、细小气肿泡自发破裂,使肺及支气管内气体进入胸膜腔所致的气胸,可分为原发性和继发性[1].胸腔闭式引流排气是目前国内外内科治疗自发性气胸常用而有效的方法[2],胸腔闭式引流病人的护理是有效促进肺复张的重要环节.

<正>肺结核是由结核分枝杆菌引起的肺部慢性传染性疾病[1]。肺结核在本世纪仍然是严重危害人类健康的主要传染病,是全球关注的公共卫生和社会问题,也是我国重点控制的主要传染病之一。肺结核病程长,即使是有效施行全程督导短程化学治
