The aim of the present study is to determine whether plasma bile acids (BAs) could be used as an auxiliary diagnostic biomarker to distinguish patients with schizophrenia from healthy controls. Seventeen different BAs were quantitatively measured in plasma of 12 healthy participants and 12 patients with schizophrenia. Then, the data were subjected to correlation and linear discriminant analysis (LDA). The concentrations of cholic acid (CA), taurochenodeoxycholic acid (TCDCA) and taurodeoxycholic acid (TDCA) were significantly decreased in plasma of the schizophrenia patients. Correlation analysis showed the concentrations of CA, TCDCA and TDCA were negatively correlated with schizophrenia. In addition, LDA demonstrated that combination of CA, TCDCA and TDCA with a classification formula could predict correctly classified cases and the accuracy of prediction was up to 95.83%. Combination of the three BAs may be useful to diagnose schizophrenia in plasma samples.
本研究旨在确定血浆胆汁酸（BAs）是否可用作辅助诊断生物标志物，以区分精神分裂症患者与健康对照者。我们定量检测了 12 名健康参与者和 12 名精神分裂症患者的血浆中的 17 种不同的 BAs，然后对数据进行了相关性和线性判别分析（LDA）。研究发现，精神分裂症患者的血浆中胆酸（CA）、牛磺鹅脱氧胆酸（TCDCA）和牛磺脱氧胆酸（TDCA）的浓度显著降低。相关性分析表明，CA、TCDCA 和 TDCA 的浓度与精神分裂症呈负相关。此外，LDA 表明，CA、TCDCA 和 TDCA 的组合与分类公式相结合，可以正确预测分类病例，预测准确率高达 95.83%。这三种 BAs 的组合可能有助于在血浆样本中诊断精神分裂症。
