Objective To study the ultrasonographic changes and blood flow characteristic ofthromboangiitis obliterans (TAO) by two-dimensional ultrasound and color Doppler imaging MethodForty-seven vessels of 40 patients with clinically suspected TAO vascular detected with two-dimensionalultrasound and color Doppler,and comparison with CT imagmg.Results Color Doppler imaging couldvisualize the arterial wall and blood flow echo filling case,and the spectrum showed the hemodynamicchanges.Conclusions Color Doppler is the first choice for the secondary check to the noninvasivethromboangiitis obliterans,close to the result by an angiography that is usually regarded as a sensitive,accurate and convenient diagnostic method.

Pulmonary fibrosis is a group of chronic lung diseases induced by various causes. Because of its complex etiology and pathogenesis,most of the pulmonary fibrosis diseases have no effective treatment currently and the quality of life and prognosis of patients are poor. Recent studies on biomarkers of susceptibility and effect associated with pulmonary fibrosis have made great progress, which is of great significance for screening and early diagnosis of the disease,and even for the evaluation of therapeutic efficacy and prognosis. This paper reviews some potential biomarkers of pulmonary fibrosis diseases,including the mucin 5B promoter variant and matrix metalloprotease-7 associated with idiopathic pulmonary fibrosis,heme oxygenase-1 and serum Se related to silicosis,Krebs von den Lungen-6,surfactant proteins-D and sphingolipids signaling associated with various pulmonary fibrosis, in order to provide new ideas for further research on the prevention and treatment of pulmonary fibrosis diseases.

Objective To evaluate the preoperative CT scanning in cardiac carcinoma.Methods 52 cases of cardiac carcinoma proved by operation and pathology were analysed.Results By CT scanning,the size of the tumor,it′s local extension and relation to the adjacent structures and lymph node metastases could be demonstrated.Conclusion CT scanning plays important role in the operability of the cardiac carcinoma and the planning of treatment.

Pulmonary fibrosis is a group of chronic lung diseases caused by various factors and characterized by chronic inflammations,lung tissue structure damage,increase of pulmonary interstitial collagen and massive deposition of extracellular matrix (ECM). Because of its complicated etiology, there is no effective treatment currently. Recent studies showed that the activation of sphingolipids signaling and pulmonary fibrosis were closely related. This paper describes the composition and function of sphingolipids signaling pathway and its effect on fibrosis in order to provide new ideas about further study of the pathogenesis of pulmonary fibrosis and methods of prevention.
