Objective To investigate the expression situation of thyroid cancer related gene-1 (TC-1),CyclinD1 andβ-catenin in the tissues of non-small cell lung cancer(NSCLC)and their relationship with the clinical pathologic characteristics,to analyze their relationship with the regulation of Wnt/β-catenin signal pathway to provide the basis for studying the role of TC-1 in NSCLC. Methods The expressions of TC-1,CyclinD1 and β-catenin in 48 patients with NSCLC were detected by immunohistochemical SP method and analyzed by combining the clinical pathological features.Results The expression levels of TC-1,CyclinD1 andβ-catenin in the NSCLC tissue were significantly higher than those in the normal lung tissue;in which,the expression of TC-1 in NSCLC tis-sue was associated with lymph node metastasis and TNM stages;the expression ofβ-catenin in NSCLC tissue was related with the pathological types and tissue differentiation degree.Conclusion The expressions of TC-1,CyclinD1 andβ-catenin show the up-regu-lating trend in NSCLC and may play an important role in the development of lung cancer;TC-1 may be involved in the regulation of Wnt/β-catenin signaling pathway,which provide the new research thought of the NSCLC targeted therapy.

Objective:To observe and compare the changes of pulmonary function in patients with pulmonary tuberculosis regular treatment for 3 months.Methods:From April 2018 to June 2019, 500 tuberculosis patients who received regular anti tuberculosis treatment in our hospital were selected.The pulmonary function of patients with pulmonary tuberculosis was measured before treatment and at the end of three months; the results of pulmonary ventilation function, lung volume, diffusing capacity, and the value of forced vital capacity (FVC), maximum expiratory volume in 1 second (FEV 1), maximum expiratory volume in 1 second/forced vital capacity (FEV 1/FVC), total lung volume (TLC), residual volume (RV), carbon monoxide diffusing capacity (D LCO) were compared. Results:252 patients with pulmonary tuberculosis were included. Before treatment and at the end of three months, the abnormal pulmonary function results were 204 cases (80.95%) and 193 cases (76.59%), respectively, and the difference was not statistically significant ( P>0.05). Among them, abnormal pulmonary ventilation function is the most common, especially with obstructive, followed by abnormal diffusing capacity. At the end of three months, the proportions of patients with normal pulmonary ventilation function and normal lung volume were higher than that before treatment ( P<0.05), but there was no significant difference in the proportion of normal diffusing capacity before and after treatment ( P>0.05). The values of FVC, FEV 1, TLC and D LCO at the end of three months were higher than those before treatment, and the difference was statistically significant ( t=-6.414, -6.754, -3.863, -3.311, all P<0.01). Conclusions:Most patients with pulmonary tuberculosis have abnormal pulmonary function. At the end of the three months treatment, the normal rates of the pulmonary ventilation function and lung volume as well as the values of FVC, FEV 1, TLC and D LCO in patients with pulmonary tuberculosis were significantly improved compared with those before treatment.
