title: [Changes in serum contents of inflammatory mediators after tetramethylene-disulfo-tetramine poisoning and clinical study of a new treatment regime for the poisoning].
abstract: OBJECTIVE
  To study the changes in serum contents of beta-endorphin (beta-EP), endothelins (ET), nitric oxide (NO) and tumor necrosis factor (TNF) after acute tetramethylene-disulfo-tetramine (TDT) poisoning and therapeutic effect of a new treatment regime.
  
  
  METHODS
  (1) Forty-eight patients with tetramethylene-disulfo-tetramine poisoning (experiment group) were enrolled in this study. The serum levels of beta-EP, ET, NO and TNF were measured upon hospitalization and 1, 3, 5, 7, 9, 11, 13, 15, 17 and 19 days after poisoning, respectively, and compared with those of 30 healthy individuals (control group B). (2) They were treated with the improved regime and compared with patients treated with the conventional regime designated as control group A.
  
  
  RESULTS
  (1) In 48 patients treated with improved regime, 45 were cured and 3 died. (2) The serum levels of beta-EP, ET, NO and TNF from 45 patients who were cured were significantly higher at hospitalization compared with those of healthy individuals, with the peak values appeared on day 1 after poisoning in the mild, moderate and severe groups. Beta-EP levels returned to normal range on days 9, 13 and 17 after poisoning respectively in the mild, moderate and severe groups. ET levels returned to normal range on days 7, 13 and 15 after poisoning respectively in the mild, moderate and severe groups. NO levels returned to normal range on days 7, 11 and 11 after poisoning respectively in the mild, moderate and severe groups. TNF levels returned to normal range on days 9, 11 and 17 after poisoning respectively in the mild, moderate and severe groups. (3) The serum levels of beta-EP, ET, NO and TNF in 3 non-survivors were very high at hospitalization and continued to increase in the course of treatment. (4) The cumulative doses of diazepam and Phenobarbital, and the eclampsia time were significantly less in the experiment group than those of control group A.
  
  
  CONCLUSIONS
  (1) The serum levels of beta-EP, ET, NO and TNF are correlated with the severity of tetramethylene-disulfo-tetramine poisoning and general conditions of the patients. (2) When the serum levels of beta-EP, ET, NO and TNF decrease gradually in the course of treatment, prognosis is better. On the contrary, the prognosis is poor when their levels increase gradually. (3) Measures to decrease levels of beta-EP, ET, NO and TNF result in a better prognosis of patients with tetramethylene-disulfo-tetramine poisoning. (4) The improved regime can be considered a better therapeutic strategy in tetramethylene-disulfo-tetramine poisoning.
