我们对98例上消化道出血患者(无肾脏病史者)测定了血、尿β_2-m含量,同时用生化方法测定血尿素氮(BUN)、血肌酐(Cr)含量进行对照。旨在探讨β_2-m在上消化道出血时的临床意义。 对象和方法 一、对象: (一)病例组:共98例(男70,女28)。均为本院住院患者,年龄20～62岁,平均47岁。临床上有呕血,黑便等症状,并按出血量多少及血压,脉搏的变化分为轻、中、重三度。同时按年龄大小分为三个年龄组(30岁以下一组、31～49岁一组、50岁以上一组)。 (二)正常对照组,共64例(男41,女23),年龄20 We measured 98 cases of upper gastrointestinal bleeding patients (no history of kidney disease) blood and urine β_2-m content, while using biochemical methods for determination of blood urea nitrogen (BUN), serum creatinine (Cr) were compared. To explore the clinical significance of β_2-m in upper gastrointestinal bleeding. Objects and methods First, the object: (a) case group: a total of 98 cases (male 70, female 28). All hospitalized patients, aged 20 to 62 years, mean 47 years. Clinical vomiting, melena and other symptoms, according to how much blood and blood pressure, pulse changes are divided into light, medium and heavy three degrees. At the same time by age divided into three age groups (a group of 30 years of age, a group of 31 to 49 years old, a group of over 50 years of age). (B) normal control group, a total of 64 cases (41 male and 23 female), age 20
