作者报告了48例急性白血病患者的骨髓髓系白血病细胞集落(AML-CFU)和粒-单核细胞集落(GM-CFU)体外培养的结果。结果表明,急非淋白血病治疗前AML-CFU数比缓解组高,而GM-CFU比缓解组低,差异显著。观察14例急非淋白血病患者治疗前AML-CFU数与预后的关系,发现AML-CFU丛/集比值具有判断预后的价值,AML-CFU数与此无关。本文还提出,AML-CFU培养用于微小残余白血病的诊断必须结合形态观察。  相似文献

目的揭示巨噬细胞集落刺激因子(M-CSF)的抗动脉粥样硬化作用是否与其保护单核细胞免受过氧化损伤有关。材料与方法用富含M-CSF的L929细胞条件培养液(L929-CM)作为M-CSF来源,以凝胶电泳、DNA断裂定量等方法观察了M-CSF对叔丁基氢过氧化物(tbOOH)诱导的U937细胞DNA断裂损伤的影响。结果tbOOH可以引起U937细胞的DNA断裂损伤,且损伤随tbOOH作用时间的延长而趋明显;而L929-CM可以减轻tbOOH诱发的U937细胞DNA断裂损伤。结论M-CSF对单核细胞具有一定的保护作用,可减轻其氧化损伤。  相似文献

目的 了解粒细胞集落刺激因子(G-CSF)和粒细胞-巨噬细胞集落刺激因子(GM-CSF)对髓系白血病细胞增殖的影响。方法 采用甲基纤维素半固体培养法培养白血病细胞集落(CFU-L),观察G-CSF和GM-CSF对11例AML和CML患者外周血CFU-L形成的影响。结果 CM-CSF对CFU-L的促进作用明显高于G-CSF(P=0.012),而G-CSF对CFU-L形成影响与对照组没有显著性差别(P=0.495)。结论 G-CSF对髓系白血病细胞体外增殖无明显影响,作为髓系白血病大剂量化疗的支持治疗可能更为安全。  相似文献

对20例急性淋巴细胞性白血病(ALL)及4例恶性淋巴瘤(ML)病儿脑脊液中的β2微球蛋白(CSF-β2M)、乳酸脱氢酶(CSF-LDH)及铁蛋白(CSF-F)进行了测定,并结合脑脊液常规和生化进行了动态观察。结果表明,中枢神经系统白血病(CNSL)组鞘内注射前及第1,2次注射后,CSF-β2M,LDH,F较非中枢神经系统白血病(NCNSL)组均有显著性升高,差异均有显著性(P<0.01~0.05)。随着CNSL治疗时间的延长,三者均逐渐下降,最终恢复正常。NCNSL组CSF-β2M及CSF-LDH均正常,有部分CSF-F升高的病儿,1~3月后发展为CNSL提示CSF-β2M,CSF-LDH及CSF-F可作为CNSL诊断和疗效观察的指标之一。NCNSL病儿CSF-F持续性升高,应警惕CNSL的发生。  相似文献

用半固体双层琼脂培养法,将白血病细胞植入底层,正常CFU-GM植入上层,作白血病细胞与正常CFU-GM的共同培养。结果发现,底层琼脂中加入0.5×105/ml的白血病细胞后,上层琼脂中的CFU-GM从对照组的193.5下降至123.1/1×105个骨髓有核细胞(BMNC),加入底层的白血病细胞增加时,CFU-GM生成进行性受抑制,当植入的白血病细胞数达15×105/ml时,几乎无CFU-GM生成。此抑制作用亦见于白血病细胞的培养上清液中。量-效关系测定发现,正常CFU-GM培养体系中加入10%的白血病细胞培养上清液时,CFU-GM生成率从对照纪的112.2下降到88.6/1×105BMNC,以后抑制效应不再增加。以上结果揭示,白血病细胞对CFU-GM的抑制是经某种体液因子实现的。  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.  相似文献
