title: [Set up drug lymphocyte stimulation test (3H-TdR) and observe its application in drug-induced liver injury].
abstract: OBJECTIVE
  To set up the drug lymphocyte stimulation test (DLST), as a diagnosis means for DILI which was immunity idiosyncrasy, improve the Diagnosis, level of DILI.
  
  
  METHODS
  For the 59 patients who diagnosed as DILI, we separated their PBMC, exploring to the suspicious drug which caused DILI, then use the methods 3H-TdR to test, according to the mixed degree to clear the PBMC count which specific activated by drug.We also set up drug group, negative control and Positive control at the same time. Preliminary experiments was including the best dose of PHA and the best concentration of the drug. We set up 40 healthy group in our experiments as a control, and explore them on the same drug every time. We test the two groups at the same time. We handled the results use t-test.
  
  
  RESULTS
  The methods 3H-TdR could be exactly reflect the PBMC's proliferation degree nearly the same when they were be stimulation by PHA or the sensitive drug. When the DILI patients were explore to the suspicious drug, their stimulation index (SI) Obviously higher than 1.8. Form this test, there were 28 in 59 patients of DILI's group were positive (47.46%), SI was from 1.9 to 43.08, the average was 22.49, the healthy group SI was lower than 1.8, the SI of DILI's group was significantly higher than healthy group (5.78+/-0.75/1.16+/-0.25, P less than 0.05). Our test suggested DLST has Higher specificity (94.92%) and sensitivity (47.46%).
  
  
  CONCLUSIONS
  DLST was significance for the patients who diagnosed as immunity idiosyncrasy's DILI, it's reflected these patients' Proliferation of PBMC when explored to the suspicious drug for the second time.
