BHMT用于检测急性中毒性肝损伤的价值

摘要

目的 分析甜菜碱高半胱氨酸甲基转移酶(BHMT)用于检测急性中毒性肝损伤的临床价值.方法 采用ELISA法检测血清样本中的BHMT,检测样本为健康体检者血清和急性中毒患者血清.结果 ELISA法检测健康体检者血清样本300例,300例健康体检血清中BHMT的平均水平为9.02 ng/mL(6.19～12.84 ng/mL).健康人群血清中BHMT水平的95％医学参考值范围为0.00～28.01 ng/mL;ELISA法检测43例急性中毒患者的血清样本,经Spearman秩相关分析,提示BHMT和丙氨酸氨基转移酶(ALT)之间有较好的正相关关系(rs=0.757 62,P＜0.001);ELISA法检测20例肾损伤病例和20例健康体检者血清中的BHMT水平,提示肾损伤患者与健康体检者血清中BHMT水平的差异无统计学意义(P＞0.05).结论 健康人群血清中BHMT水平的医学参考值范围为0.00～28.01 ng/mL;急性中毒患者血清中的BHMT与其对应的ALT之间有很好的正相关关系;BHMT水平的变化可能与肾损伤无关,其反映肝损伤的特异性较好,因此推测BHMT可能是更好的急性肝损伤的血清学标志物.%Objective To analyze the value of the serum BHMT for diagnosis of hepatic injury in patients with acute poisoning.Methods ELISA method was used to detect BHMT in serum samples,and the samples were detected in the sera of normal persons and patients with acute poisoning.Results 300 samples were detected in the sera of normal persons by ELISA method.The average level of human serum B HMT content in 300 samples was 9.02 ng/mL(6.19-12.84 ng/mL),and the 95 ％ medical reference value of BHMT content in healthy people ranges from 0.00 to 28.01 ng/mL.BHMT and ALT were detected in 43 samples from acute liver injury,the Spearman analysis indicating a good positive correlation between BHMT and ALT(rs =0.757 62,P＜0.001).The comparison of the content of BHMT was made between the serum samples from 20 renal damage patient and 20 normal human serum,there was no significant difference in the BHMT content between the serum of patients with renal injury and the normal human serum(P＞0.05).Conclusion The medical reference value range for of serum BHMT content in healthy population ranges from 0.00 to 28.01 ng/mL.There was a good positive correlation between BHMT and ALT.BHMT might not be closely related to kidney injury,while be more specific to liver injure.BHMT could be a better marker of acute poisoning liver injury.
