目的??观察二丁酰环磷腺苷钙综合治疗放射性肺炎的临床疗效。 方法??选取肺癌放疗后引起放射性肺炎 2、3、4 级患者 30 例，随机分为观察组和对照组。对照组予吸氧、糖皮质激素、祛痰、抗氧自由基及抗生素治疗，3 级以上加用氨 茶碱治疗。治疗组在对照组的基础上加用二丁酰环磷腺苷钙静滴，两周后评价近期疗效。 ?结果??治疗组有效率优于对照组 （P<0.05）。 结论??二丁酰环磷腺苷钙综合治疗肺癌放疗后放射性肺炎有效。

Objective To observe the clinical effcacy of DBC AMP-Ca in the treatment of radiation pneumonitis. Methods 30 patients with lung cancer, complicating 2, 3 and 4 degree of radiation pneumonitis were randomly divided into treatment group and control group. Patient in control group were given oxygenaton, glucocorticoid, expectorant, clearing oxygen free radical and antibiotic treatment, while those with more than 3 degree of radiation pneumonitis aminophylline was used. Patients in treatment group received DBC AMP-Ca intravenously based on the treatment of control group. The effects were compared after two weeks. Results The efficiency of DBC AMP-Ca in treatment of radiation pneumonitis is superior to that of control group (P<0.05). Conclusions DBC AMP-Ca is effective for radiation pneumonitis in patients with lung cancer caused by radiotherapy.
