Objective: To investigate the effect of reduced glutathione combined with polyene phosphatidylcholine on liver function, liver fibrosis indexes and serum inflammatory factors in patients with acute drug-induced liver injury (ADILI). Methods: 100 patients with ADILI who were admitted in our hospital from January 2017 to March 2019 were selected, they were divided into control group and combination group by random stratified sampling method, 50 cases in each group. The control group was treated with polyene phosphatidylcholine, the combination group was treated with reduced glutathione combined with polyene phosphatidylcholine, the curative effect, liver function indexes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and glutamyltranspeptidase (GGT)], liver fibrosis indexes [laminin (LN), procollagen type III (PC-III), type IV collagen (IV-C), hyaluronidase (HA)], serum inflammatory factors [Interleukin-6 (IL-6), tumor necrosis factor -α(TNF-α), interleukin-2 (IL-2)] and adverse reactions were compared between the two groups. Results: The total effective rate of the control group was 79.00% (38 / 50), the total effective rate of the combination group was 94.00% (47/50), the total effective rate of the combination group was higher than that of control group (P<0.05). 4 weeks after treatment, the levels of ALT, AST, TBIL, GGT, LN, PC-III, IV-C, HA, IL-2, TNF-α, IL-6 in the two groups were decreased compared with those of before treatment, and the combination group was lower than the control group (P<0.05). There was no difference in the incidence of adverse reactions between the two groups during treatment (P>0.05). Conclusion: On the basis of polyene phosphatidylcholine, combined with reduced glutathione treat patients with ADILI, the curative effect is good, which can improve liver function and indicators of liver fibrosis, reduce the body's inflammatory response, and it's safe and reliable.
