ABSTRACT
Objective To investigate the observation effect of Fuji intelligent chromoendoscopy (FICE) in central type lung cancer,to select the optimal wavelength combination and to explore its diagnostic value for central type bronchogenic lung carcinoma. Methods One hundred and forty-six cases of definite histopathological diagnosis by bronchoscopy examination with preserved intact data in the Chongqing Municipal Tumor Hospital from January 2016 to October 2016 were included into this study. The white light bronchoscopy(WLB) and FICE were used to conduct the observation respectively. The capillary morphology was respectively scored by using the 10 wave combinations in FICE. The best wave combination was selected for conducting the forceps biopsy. Finally the pathological results served as the gold standard for conducting the comparative study. Results The difference of lesion observation effect among 10 sets of FICE wave combination had statistical significance (P<0.01), the wave combination 8 [R= 540 (2), G= 505 (4), B= 420 (5), wavelegnth(nm gain value)] was superior to that of other wave combinations in observing lesion vascular texture (Rank% = 9.74). The coincidence rate of FICE for judging the lesion property was 88.4 %. The detection rate of FICE combined with WLB for central type lung cancer was 96.6 %, compared with that of single WLB, the detection rate had statistically significant difference (P<0.01). Conclusion FICE wave combination 8 [R= 540 (2) ,G=505 (4),B=420 (5) ,wavelength(nm, gain value)] is most ideal for observing superficial mucosal capillary vascular morphology of central type lung cancer lesion tissue.
ABSTRACT
Objective To evaluate the role of heparin in treating thrombotic diseases by interventional radiology.Methods In order to perform general anticoagulation, heparin or small molecule heparin were used for patients with acute brain thrombosis in 22 cases, limb artery thrombosis in 18 cases, ilic and formal vein thrombosis in 200 cases, inferior vena cava thrombosis in 20 cases. All patients were treated by thrombolysis with UK, or placing filter in inferior vena cava simultaneously with heparin. Results Under general anticoagulation, the effects of thrombosis dissolution for artery were positive. After thrombolysis, heparin must be used to keep the vascular patency. The recanalization of iliac and formal veins was lower than that of artery. The effect of applying heparin combined with thrombolysis was better than that of thrombolysis alone. Conclusions During the course of therapy of thromobotic diseases application of heparin should be the first and their follow by thrombolysis that is the principle for interventional therapy.
