Patients in the control group received edaravone treatment, while patients in the observation group received bailing capsule combined with edaravone treatment. The levels of T lymphocyte, superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO), transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-9 (MMP-9) were measured and compared before and after treatment.Result: After treatment, the levels of CD3+, CD4+, CD4+ / CD8+, SOD and NO of patients in the control group and the observation group were significantly higher than those before treatment, while the levels of CD8+ and MDA were significantly lower than those before treatment. The change trend of the levels of T lymphocyte and antioxidant enzyme of patients in the observation group were significantly more obvious than that in the control group (P<0.05). After treatment, the serum levels of TGF-β1, TNF-α and MMP-9 of patients in the control group and the observation group decreased significantly, and the change trend of the above factors of patients in the observation group was more obvious than that in the control group (P<0.05).Conclusion: Bailing capsule combined with edaravone in the treatment of chronic obstructive pulmonary disease can significantly enhance the immune function and antioxidant function of patients and alleviate inflammation of the body. It has good clinical curative effect.展开更多

Our framework takes full advantage of spatio-temporal-contour consistency. It exploits the property to interpolate single contours, two neighboring contours which belong to the same model, and two contours which belong to the same view at different times, corresponding to point-, contour-, and model-level interpolations, respectively. The framework formulates the interpolation of two models as point cloud transport rather than non-rigid surface deformation. Our framework speeds up the reconstruction of a dynamic scene while improving the accuracy of point-pairing which is used to perform the interpolation. We obtain a higher frame rate, spatio-temporal-coherence, and a quasi-dense point cloud sequence with color information. Experiments with real data were conducted to test the efficiency of the framework.展开更多
