title: [Shuxuening injection combined with routine therapy in treating patients with active ulcerative colitis: an analysis of efficacy ].
abstract: OBJECTIVE
  To observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).
  
  
  METHODS
  Totally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.
  
  
  RESULTS
  Totally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).
  
  
  CONCLUSIONS
  SI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.
