采用随机分组研究方法，比较了榄香烯乳加白细胞介素-2（联合组）与单纯白细胞介素-2（单药组）治疗38例恶性胸腔积液的临床疗效。结果显示，联合组有效率为89．74％，而单药组有效率为57．89％。两组有显著性差异（P＜0．05）。联合组疗效肯定，但有发热、胸痛等副作用。经对症处理可缓解。榄香烯乳与白细胞介素-2联合应用治疗恶性胸腔积液有一定推广价值。 Randomized grouping study was used to compare the clinical efficacy of Elemene plus Lactin-2 (combined group) and Interleukin-2 (single drug group) in the treatment of 38 cases of malignant pleural effusion. The results showed that the combined group had an effective rate of 89.74%, while the single-agent group had an effective rate of 57.89%. There was a significant difference between the two groups (P<0.05). The efficacy of the combined group was positive, but there were side effects such as fever and chest pain. Symptomatic treatment can ease. Elemene milk and interleukin-2 in the treatment of malignant pleural effusion have some popularization value.
