The clinical significance of NO expression in the phase of periodic paralysis stoke / 中国综合临床

Objective To find out the effect of NO on the stroke of periodic paralysis.Methods Blood potassium,NO and NOS were measured in patients with hypokalemic periodic paralysis during paralysis stroke and after muscle power recovered.The relationship between NO and NOS and paralysis in the different phase was observed.Results NO and NOS decreased obviously in the phase of paralysis,which tended to be normal with recovering of blood potassium and muscle power after treatment.The change of NO was positively correlated with the decreasing degree of blood potassium(r=0.3511,P

Solitary Pulmonary Nodule:Diagnosis with Thin-slice Reconstruction of Multi-slice Spiral CT / 实用放射学杂志

Objective To study the diagnostic value of thin-slice reconstruction of multi-slice spiral CT(MSCT) in solitary pulmonary nodule(SPN).Methods 55 cases of SPN confirmed by pathology were analysed retrospectively.All cases underwent chest MSCT scan and thin-slice reconstruction images were obtained at 10.0 mm,5.0 mm,2.5 mm and 1.25 mm thickness.The detecting rate of CT findings of SPN on different thickness CT images was evaluated,and the effect of thin-slice images and traditional CT scan in diagnosing benign and malignant pulmonary nodules ?2 test.Results(1)In detecting rate of CT findings of SPN,the thin-slice(1.25 mm) reconstruction was better than traditional CT(P
