Objective To explore the manifestations of chest multi-slice spiral CT in patients with initial infection of swine-origin influenza A (H1N1) virus (S-OIV). Methods The chest multi-slices spirals CT images of 19 firstly diagnosed patients with swine-origin influenza A (H1N1) in our institution were retrospectively studied. CT manifestations were evaluated by three experienced radiologists. Location, appearance of lung abnormalities, abnormal distribution, pleural effusion and others (pericadiaum, lymphadenopathy and pleural thickening) were observed and quantitatively analyzed. The correlation of ground-glass and consolidation CT scores with the fever time was studied. Results The abnormal CT findings were observed bilaterally in 18 of 19 subjects including ground-glass (n= 3), consolidation (n=3 ), consolidation accompanied with ground-glass (n=12). Most of these lesions were distributed diffusively (n=14) while the others located in the middle and low lobes (n= 4). Unilateral (n=3) or bilateral (n=2) pleural effusion were observed. Lymphadenopathy (n=2), effusion of pericadium (n=1), pleural thickening (n=1) and cardiac enlargement (n=2) were also found in patients with H1N1. CT scores of ground-glass were 4. 25(n=2),3.75 (n=1),2.25(n=1),1.75(n=1),1.00(n=6),0.75(n=2), 0.50(n=2),0(n=4).CT scores of consolidation were4.25(n=1),4.00(n=1),3.75 (n=1), 2.75(n=1),1.25(n=3),1.00(n=2),0.75(n=2),0.50(n=1),0.25(n=3),0(n=4). CT scores of ground-glass were significantly correlated with the fever time (r= 0.776, P < 0.01), CT scores of consolidation had no correlation with the fever time(r=0.322,P > 0.01). Conclusions The most common CT findings in patients with S-OIV infection are diffuse distribution of bilateral ground-glass opacities with or without associated focal or multifocal areas of consolidation. The increasing of ground-glass's range could be the marker of progression of H1N1 pulmonary infection at initial stage.

Objective To assess the effect of aortic valve replacement (AVR) on left ventricular (LV) twist function in severe aortic stenosis (AS) patients with preserved LV ejection fraction (LVEF) by speckle tracking imaging (STI).Methods Twenty-eight severe aortic stenosis (AS) patients (17 male,age 64.1 ± 10.4 years) with normal LVEF (≥50%) were examined by STI before and six months after AVR.The standard mitral valve and apical short-axis views were obtained to analyze LV basal and apical peak systolic rotation.LV peak systolic twist was calculated as the different between apical rotation and basal rotation.LV fractional shortening (LVFS) was calculated as the percentage fall of LV systolic dimension with respect to diastolic dimension.The data were compared with 28 age and sex-matched normal controls.Results In patients,LVEF remained unchanged after AVR.LV twist increased before (19.7° ± 5.7° vs 12.9° ± 3.2°,P <0.001) because of increased apical rotation (13.0° ± 5.8° vs 7.6° ± 2.6°,P <0.001),and normalized after AVR (14.4°± 5.2°,P <0.001).In controls,LV twist correlated with LVFS (r =0.81,P < 0.001),this relationship was reversed in patients before (r =0.52,P <0.01) and after AVR (r =0.34,P >0.05).Conclusions In patients with severe AS and normal LVEF,LV twist is exaggerated suggesting potential compensation for reduced long axis function.These disturbances normalize within six months of AVR but lose their relationship with basal LV function.

Objective To discuss the clinical features and therapeutic effects of adrenogenital syndrome in children. Methods Clinical and follow up data were summarized for 42 children with adrenogenital syndrome, including 30 cases of congenital adrenal hyperplasia (CAH) and 12 cases of adrenal cortex tumor. Results Endocrine function examination in 15 cases of CAH showed that 24h urine 17 KS was elevated in 10 cases and normal in 5.There was obvious clitorism in all 30 CAH children and urogenital sinus malformation in 28.Of the 12 cases of adrenal cortex tumor 7 had sexual abnormality and hypercortisolism simultaneously.Clitoris shortening or clitoridectomy was performed in CAH cases plus vaginal vestibule plasty simultaneously.Of the 12 cases of adrenal cortex tumor 10 underwent complete tumor resection;1 partial tumor resection and the remaining 1 declined treatment.During the follow up 8 case of cortex tumor,4 cases of adenoma survived tumor free with an average survival time of 7.5 years;2 cases of cortex carcinoma survived tumor free for 3 and 4 years;while the other 2 cases died soon after discharge. Conclusions The diagnosis can be established based on clitorism,labium confluence or male sexual precocity,increase in urine 24h 17 KS and blood testrone.Cortex hormone should be taken early,properly,life long in CAH patients,and appropriate perineoplasty should be performed.Early detection and resection of tumor is the key point for treating adrenogenital syndrome caused by cortex tumor.
