ABSTRACT

Objective To investigate the effects and mechanism of deoxypodophyllotoxin on cell proliferation and mi?gration of human lung cancer NCI-H358 cells in vitro. Methods CCK-8 assay, flow cytometry assay, wound healing assay and DCFH-DA assay were used to detect the effects of deoxypodophyllotoxin on the proliferation, cells cycle, apoptosis, mi?gration and reactive oxygen species (ROS). The protein expressions of Cyclin B1, Cdc25c, CDK1, Caspase-3, p53, Bcl-2, MMP9, ERK1/2, p38MAPK and JNK were measured by Western blot assay, respectively. Results Deoxypodophyllotoxin inhibited cell proliferation and reduced migration in human lung cancer NCI-H358 cells. Flow cytometry analysis showed that treatment with deoxypodophyllotoxin resulted in cell cycle G2/M and S phase arrest, cell apoptosis and ROS production. The result of Western blot assay showed that protein expressions of Cyclin B1, Cdc25c, CDK1, Bcl-2 and MMP9 were down-regulated while Caspase-3 and p53 were up-regulated. Moreover, Deoxypodophyllotoxin treatment decreased the phosphory?lated levels of ERK1/2, p38MAPK and JNK obviously. Conclusion Deoxypodophyllotoxin could suppress the proliferation and migration of human lung cancer NCI-H358 cells in vitro, which is a potential anti-tumor drug.

ABSTRACT

Objective To investigate the effect and safety of bronchial balloon positioning combined with autologous blood bronchial occlusion in the treatment of intractable pneumothorax.Methods 36 cases of hospitalized patients with refractory spontaneous were collected as the research object,based on the bronchial balloon positioned upstream bronchoscopy combined with autologous blood bronchial occlusion therapy.The efficacy and adverse reac-tions were followed up for one year.Results In the 36 cases of spontaneous pneumothorax in patients with refractory, 30 patients were successfully positioning balloon (83.33%),6 cases of patients who were not successfully positio-ning,were continued with conservative treatment of indwelling thoracic drainage.In 30 patients underwent successful positioning,autologous blood bronchial occlusion were used,and a total of 24 cases (80.0%)patients successfully reduced bubbles escape;6 patients relapsed,who were continued to retainthoracic drainage conservative treatment. Conclusion Bronchial balloon positioning combined with autologous blood bronchial occlusion in the treatment of intractable pneumothorax has accurate positioning and high blocking success rate,and also is safe and effective.It is worth promoting in clinical practice.

ABSTRACT

Objective:By analyzing clinical data, discuss the clinical efficacy of balloon dilatation for the treatment of tuberculous scarred airway stenosis and factors affecting efficacy. Methods:Selected 13 cases airway stenosis caused by tracheobronchial tuberculosis.Airway stenosis was confirmed and measured by bronchoscopy and CT before balloon dilation. Balloon dilatation with forming expansion was conducted once a week. We evaluated the shortness of breath scores, measuring FEV1, FVC and the diameter of airway before and after dilation. The long-term outcome and lung function improvement were evaluated. Results:Thirteen cases were treated by balloon dilation with fiberoptic bronchoscopy. The airway diameter before and after the treatment, shortness of breath score, FEV1, FVC have improved significantly, the difference was significant(t=15.596, t=-27.657, t=-14.604, t=-41.766;P<0.05). Conclusion:Balloon dilation treatment for tuberculous scarred airway stenosis can achieve better results.
