Objective To explore the curative effect and prognosis of traditional Chinese medicine combined with western medicine in the treatment of silicosis patients.Methods 74 patients with silicosis were selected as the research subjects.According to the admission time,the patients were divided into the observation group and the control group,37 patients in each group.The control group was treated with conventional western medicine,the observation group was given the combined treatment of traditional Chinese medicine and western medicine.The clinical curative effect,pulmonary function index,symptoms improved time and the reduce of lung shadow were observed and compared.Results The reduction rate of lung shadow in the observation group was 75.67％,which in the control group was 62.16％,there was statistically significant difference between the two groups (u =2.419,P =0.015).The total effective rate of the observation group was 86.49％,which of the control group was 67.57％,there was statistically significant difference between the two groups (u =2.116,P =0.034).After treatment,the vital capacity (VC),forced vital capacity(FVC) and the first second forced expiratory volume (FEV1) in the observation group were (69.15 ± 18.34)％,(71.08 ± 16.93)％,(68.91 ± 18.75)％,respectively,which in the control group were (63.37 ± 20.53) ％,(63.13 ± 18.69) ％ and (55.47 ± 17.58) ％,respectively,which in the two groups were higher than those before treatment,which in the observation group increased significantly,there were statistically significant differences between the two groups (t =6.778,P =0.000,t =8.836,P =0.000,t =10.133,P =0.000).The wheezing,cough,pulmonary rales and other symptoms improved time in the observation group were shorter than those in the control group,the differences were statistically significant (t =8220,P =0.000,t =6.836,P =0.000,t =6.909,P =0.000).Conclusion Traditional Chinese medicine combined with western medicine in the treatment of silicosis has higher reduction rate of lung shadow,lung function improved significantly,shorter improved time of cough,wheezing and other symptoms,its curative effect is better than western medicine.
