唾液酸的本质是神经氨酸的乙酰化衍生物.早年认为系由肿瘤细胞所分泌,并将其作为肿瘤标忐,用于病人胸、腹水肿瘤的鉴别诊断.近年研究发现,血清唾液酸浓度升高的心血管病人群中,死亡率相应升高 而且随着受检人员的年龄增大.血清唾液酸测定值也逐渐升高.因而认为.本检查对肿瘤的辅助诊断、疗效估计、心血管病预后的判断及衰老机理的研究均具有重要意义.
The nature of sialic acid is an acetylated derivative of neuraminic acid. In the early years, it was thought that it was secreted by tumor cells and used as a tumor marker for the differential diagnosis of patients with thoracic and ascites tumors. Recent studies have found that serum sialic acid concentration In an elevated group of cardiovascular patients, the mortality rate increases accordingly and as the age of the subjects to be examined increases, serum sialic acid values also gradually increase. Thus, it is considered that the present examination supports the diagnosis of tumors, the evaluation of the therapeutic effects, and the The prognosis of vascular disease and the study of aging mechanism are of great significance.
