RESUMO
Objective To investigate the curative effect of modified Yanghe decoction on pulmonary interstitial fibrosis.Methods In this study,62 patients suffering fiom pulmonary interstitial fibrosis were randomly divided into 2 groups with the use of the Random Number Table method.31 cases in the treatment group were treated with modified Yanghe decoction,while 31 cases in the control group were treated with prednisone,40 mg/d (produced by Zhejiang Xianju Pharmaceutical Factory).The dosages of prednisone were gradually reduced a month later.The changes and improvement in symptoms,pulmonary function,chest CT,etc were observed and analyzed after three month.Results The study showed that the total?effective?rates of the treatment group and control group were 83.9％ (26/31) and 58.1％ (18/31) respectively,and the difference had statistical significance (P=0.031,P＜0.05).The integrals of gasping,breathlessness,cough and Velcros Rale of the treatment group before the treatment were (3.1 ± 2.61),(4.1 ± 1.53),(1.38 ± 1.02),(1.56 ±2.34)respectively while those of the control group were (2.83±2.34),(3.90±1.67),(1.28±1.24),(1.61±2.14) respectively.The after-treatment integrals of the treatment group were (1.1 ± 1.06),(1.52± 1.40),(0.36±0.71),(0.65±0.67)respectively while those of the control group were(1.2± 1.33),(2.15±1.31),(0.41±0.70),(0.78 ± 0.30)respectively.Compwered with their symptoms before the treatment,there was obviousimprovement in the symptoms of both groups after the treatment,(P＜0.05),but the difference in these aspects between the two groups had no statistical significance (P＞0.05).Before the treatment,the total lung capacity,vital capacity,diffusion function,arterial oxygen pressure of the treatment group were (69.80±21.7) ％,(73.16±16.38) ％,(51.46± 16.42) ％,(69.70± 10.74) mm Hg (1 mm Hg=0.133 kPa) respectively while those of the control group were(77.52 ± 15.96)％,(74.57 ± 20.73)％,(55.68 ± 17.27)％,(64.86 ± 11.40)mm Hg respectively.After the treatment,the total lung capacity,vital capacity,mass function,arterial oxygen pressure of the treatment group were (82.31±21.65)％,(83.66±17.32)％,(62.34±17.96)％,(83.51±9.37)mm Hg respectively while those of the control group were (85.06± 16.10) ％,(85.72± 20.40) ％,(68.32± 20.16) ％,(79.61 ±9.41)mm Hg respectively.Compwered with their symptoms before the treatment,there was obvious improvement in the symptoms of both groups after the treatment (P＜0.05),but the difference in these aspects between the two groups had no statistical significance (P＞0.05).Conclusion Modified Yanghe decoction can be effectively applied in the prevention and treatment of pulmonary interstitial fibrosis.
