白血病、肾病患者糖皮质激素受体的放射分析及其临床意义
Receptor Radio-ligand Binding Assay of GCR in Leukemia and Nephrotic Syndrome Patients and Its Clinic Significance
-
摘要: 采用受体放射配体结合技术测定了 5 0例正常健康成人、18例健康儿童、5 0例急性淋巴细胞白血病 (ALL )患者和 33例肾病综合症 (NS)患者外周血淋巴细胞糖皮质激素高亲和力受体 GCRH 和低亲和力受体 GCRL 位点数, 分析 GCR与疗效的关系;对 NS患者还检测了血浆 ACTH、皮质醇水平, 探讨了 NS发病及疗效机制;同时还通过动物实验观察了中药名方小柴胡汤对应用 GC所产生的 GCR“降调节”效应的影响。结果表明: AL L患者治疗前 GCRH>4 0 0 0位点 /细胞的患者对激素联合化疗疗效好, AL L患者在激素联合化疗后 GCRH 明显降调, 但 GCRL 治疗前后无明显变化;NS患者治疗前 GCRH>6 0 0 0位点 /细胞的患者对 GC疗效好, GCRH<30 0 0位点 /细胞的患者对 GC治疗无效;所以对 AL L、NS患者疗前了解 GCR水平, 有助于制定个体化的治疗措施。 SD大白鼠实验研究表明, 小柴胡汤具有调控 GCR的作用Abstract: GCR H and GCR L levels are measured using receptor radio ligand binding assay in healthy control group (50 cases adults, 18 cases children) and the patients with acute Leukemia (50 cases) or Nephrotic Syndrome(NS) (33 cases). The study is emphasized in the relationship between GCR H level of acute leukemia and the effect of hormone chemistry complex therapy. The results indicate that the patients with GCR H more than 4 000 sites/cell have good short term prognosis, whereas less than 4 000 sites/cell have poor short term prognosis. The NS group is found that patients of GCR H more than 6 000 sites/cell are sensitive or hypo sensitive to GC therapy, patients of GCR H less than 3 000 sites/cell are notresponsible to GC therapy. The binding capacity of GCR H of hepatic cytosol are measured in 40 SD male rats. The results indicate that XCHT might have two sided effect on GCR H regulation.
