双黄升白冲剂对化疗引起骨髓抑制的临床研究及小鼠骨髓超微结构的观察

目的：观察中药双黄升白冲剂对肿瘤化疗患者的升白疗效及对小鼠骨髓造血微环境的作用。方法：选择主要为复治的非小细胞肺癌及乳腺癌、胃癌、肠癌患者，随机分为4组。治疗1组（28例）为化疗同时服用双黄升白冲剂；治疗2组（27例）为WBC＜4×10^9/L始用双黄升白冲剂；对照1组（３３例）为化疗同时服用茜Ｚhuo双酯，对照２组（２４例）为ＷＢＣ＜４×１０^９／Ｌ始用茜Ｚhuo双酯，并做实验研究电镜观察小鼠骨髓超微结构。结果：升白疗效总有效率治疗１组为７５.００％，治疗２组为８８.８９％；对照１组为５４.５５％，对照２组为５８.３３％，治疗组与对照组比较差异有显著性（Ｐ＜０.０１）。双黄升白冲剂对小鼠骨髓有良好的保护、改善造血微环境的作用。结论：中药双黄升白冲剂对化疗后骨同须受抑制肿瘤患者具有明显的保护和治疗作用。

Clinical and Experimental Study on Effect of Shuanghuang Shengbai Granule on Myelosuppression Induced by Chemotherapy and Ultrastructure Observation of Bone Marrow in Mice

OBJECTIVE: To observe the leukocyte increasing effects of Shaunghuang Shengbai Granule (SHSBG) in tumor patients treated by chemotherapy (CT) and its function on bone marrow hematopoietic microenvironment in mice. METHODS: Patients of non-small-cell lung cancer and breast, gastric or intestinal cancer, who were retreated with CT, were enrolled and divided into 4 groups randomly. The 28 cases in the treated group 1 received SHSBG and CT simultaneously. The 27 cases in the treated group 2 also received firstly CT, and SHSBG started when WBC count lowered to less than 4 x 10(9)/L after CT. The control group 1 and 2 (n = 33 and n = 24) was treated by the method similar to that applied to the treated group 1 and 2 respectively but with Rubidate instead of SHSBG. Experimental study of observing bone marrow ultrastructure in mice was also conducted with electron microscopy. RESULTS: The total leukocyte increasing effective rate occurred in the treated group 1 was 75.00%, that in the treated group 2 was 88.89%, in the control group 1 was 54.55% and in the control group 2 was 58.33%. There was significant difference between the treated groups and the control groups (P < 0.01). Experimental study showed that SHSBG has good bone marrow hematopoietic microenvironmental protecting and improving effect in mice. CONCLUSION: SHSBG has obvious protecting and treating effect on CT caused bone marrow suppression in tumor patients.
