ABSTRACT
Objective:To establish a determination method of high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)for serum hydrogen sulfide(H2S),so as to determine serum H2S.Methods:This study collected serum samples of 30 patients who admitted to Beijing Jishuitan Hospital affiliated to Capital Medical University from April 2023 to May 2023,and they were divided into osteoporosis group and control group according to whether existed osteoporosis,with 15 cases in each group.HPLC-MS/MS and enzyme-linked immunosorbent assay were used respectively to determine serum H2S.And then,the precision,accuracy and correlation between the two methods were evaluated.Results:HPLC-MS/MS can fast detect the content of serum H2S through detecting methylene blue in the serum,which analysis time was only 1.5 minutes,and its specificity was higher.The relative standard deviation(RSD)value of quality control plasma was 8.77%,and that of quality control plasma with the standard and pure water with standard were respectively 4.58% and 8.23%.The precisions of them met the requirement of detection(less than 20%).The recovery was 103.5% through used the above data,and the accuracy accorded with the requirements of quantitative detection(recovery was 103.5%).Conclusion:HPLC-MS/MS method is rapid and accurate in detecting H2S,which can accurately detect the content of serum H2S.This method has a series of advantages include fast,high throughput,high sensitivity and favorable stability,which contributes to conduct basic research of the content of serum H2S in the cellular pathways of human.
