β因子是补体旁路途径中最重要的成份之一。国外于70年代初、国内于80年代初才开始报告有关资料。令人注目的是:恶性肿瘤患者血清中β因子含量显著上升。为探讨其临床意义,我们对117例各类恶性肿瘤患者及80例正常人进行检测,现将结果报告如下。 材料和方法 经病理或X线诊断的117例患者按病情及疗效分为三组:(a)未经治疗或治疗无效者58例;(b)综 The beta factor is one of the most important components of the complement bypass pathway. In the early 1970s, foreign countries started to report relevant information in the early 1980s. What is remarkable is that the content of β-factor in the serum of patients with malignant tumors is significantly increased. To explore its clinical significance, we detected 117 cases of various types of cancer patients and 80 normal subjects, the results are reported as follows. Materials and Methods 117 patients diagnosed by pathology or X-ray were divided into three groups according to their condition and efficacy: (a) 58 patients were untreated or treated ineffectively; (b)
