Results There were significant differences between MDS and CAA in Hb, red cell distribution width-coefficient variation, immature reticulocyte fraction, BPC, the ratio of G1 (the sum percentage of myeloblast and premyelocyte) to G2 (the sum percentage of neutrophilic myelocyte and metamy-elocyte), the ratio of E1 (the sum percentage of proerythroblast and early erythroblast) to E2 (the sum percentage of intermediate erythroblast and late erythroblast), megakaryocyte count,erythroblast PAS, neutrophil alkaline phosphatase, and serous levels of indirect bilirubin,lactose dehydrogenase, folic acid, VitBl2 and ferritin.

Methods Totally 173 patients diagnosed as MDS according to FAB or WHO criteria with complete clinical and cytogenetical data were included in this reseach.

方法应用骨髓细胞短期培养法和染色体G显带技术，部分病例联合应用荧光原位杂交技术，对42例细胞遗传学检查具有+8异常克隆，16例具有-7/7q-异常克隆，以及55例虽然经常规细胞遗传学检查未检出异常克隆，但是骨髓涂片原始细胞≥0.10，按照FAB或WHO标准既往诊断为MDS的病例进行了临床及血液形态学和细胞遗传学的系列研究。

Methods Totally 173 patients diagnosed as MDS according to FAB or WHO criteria with complete clinical and cytogenetical data were included in this reseach. Among them 42 had +8 chromosome aberration, 16 had -7/7q-, and 55 had normal karyotypes and more than 0.10 blast cells in the bone marrow. Short term culture and G-banding techniques and in some specimens fluorescence in situ hybridization method were used to do chromosome analysis.
