Objective:To study the sTRAIL levels in chronic hepatitis B(CHB) patients upon nucleoside analogues therapy.Methods:Serial sera of 60 CHB patients before and after nucleoside analogues therapy were collected,among which there were 20 complete responding cases,20 partial responding cases,20 non-responding cases,and 10 healthy people.The level of sTRAIL,IFN-γ and ALT were detected.Results:The level of sTRAIL,IFN-γ and ALT of CHB patients were higher than that of normal group.The sTRAIL level of complete responding group at 4 weeks and partial responding group at 12 weeks were lower than those before therapy,while serum TRAIL of complete responding group were lower than those of partial responding group at 4 weeks.The IFN-γ level of complete responding group at 4 weeks and partial responding group at 12 weeks were higher than those before therapy.ALT levels of all groups in the course of therapy declined gradually and significant difference was observed at different time point.Conclusion:Serum TRAIL level can be used as an early marker for efficacy of nucleoside analogues therapy efficacy in CHB patients.sTRAIL may play a role in restoring immune injury of early anti-viral response in patients with hepatitis B.

Objective To compare the therapeutic effect of conventional treatment and conventional treatment plus external application of Shuangbai Powder for patients with wounded limb injured by venomous snake. Methods One hundred patients bitten by venomous snake were randomized into treatment group and control group, 50 cases in each group. The control group was given conventional treatment including repeatedly washing the wound with hydrogen peroxide, debriding the wound, letting blood and draining toxicity, local blocking with chymotrypsin, wet packing the wounded limb with magnesium sulfate, and injection with anti-venomous serum, tetanus antitoxin, antibiotics, furosemide and energy mixture. The treatment group was given external application of Shuangbai Powder on the basis of the treatment for the control group. Both groups were given the comprehensive nursing of psychological nursing, wound nursing, dietary nursing, defecation nursing and functional nursing. The swelling-subsiding time for the wounded limb and pain scores of visual analogue scale (VAS) in the two groups were compared. Results(1) After treatment, swelling-subsiding time for the wounded limb of the treatment group was shorter than that of the control group, the difference being statistically significant (P < 0.05). (2) After treatment for 4 days and at the end of the treatment, VAS scores of the two groups were decreased compared with those before treatment(P < 0.05), and the decrease of VAS scores in the treatment group after treatment for 4 days was superior to that in the control group (P < 0.05). Conclusion The conventional treatment plus external application of Shuangbai Powder is an effective therapy for patients with wounded limb injured by venomous snake by shortening swelling-subsiding time and relieving pain for the wounded limb .
