OBJECTIVE:To observe the efficacy and safety of moxifloxacin combined with Jiehe pill in the treatment of muilt drug-resistant tuberculosis(MDR-TB). METHODS:116 patients with MDR-TB were randomly divided into control group and ob-servation group. Control group was given Moxifloxacin hyohochloride tablet 0.4 g once a day,observation group was additionally given Jiehe pill 9 g,twice a day,and 2 groups were given rifapentine,albendazole isoniazid,amikacin,pasiniazide,pyrazin-amide,p-amino salicylic acid and other conventional treatment. The treatment course for both groups was 18 months. The clinical efficacy,and T cell subsets (CD3+,CD4+,CD4+/CD8+),interferon(INF)γ,interleukin(IL)4 levels before and after 6,12 and 18 months,and incidence of adverse reactions in 2 groups were recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,CD3+,CD4+,CD4/CD8 and INF-γ level in 2 groups were significantly higher than before and gradually increased by time,and observation group was high-er than control group;IL-4 level was significantly lower than before and graually decreased by time,and observation group was lower than control group,the differences were statistically significant(P<0.05). There was no significant difference in the inci-dence of adverse reactions(P>0.05). CONCLUSIONS:Based on the coventional treatment,moxifloxacin combined with Jiehe pill has better efficacy than moxifloxacin in the treatment of MDR-TB,with similar safety.

Objective To analyze the reliability and reproducibility of three different classification systems of Tile,Young Burgess and AO in pelvic fracture.Methods One hundred cases of pelvic fractures conforming to the inclusion standard and with intact imaging data were selected and classified according to these 3 classification methods by the orthopedic surgeons.The retyping was performed at 8 weeks after disorganizing the order.Then reliability and reproducibility analysis was performed by using the Kappa values and typing consistency.Results The reliability Kappa values during the two periods before and after the Tile classification were 0.743 and 0.745 respectively,and the reproducibility Kappa value was 0.771;the reliability Kappa values during the two periods before and after the Young-Burgess classification were 0.587 and 0.590 respectively,and the reproducibility Kappa value was 0.691;the reliability of Kappa values during the two periods before and after the OA classification were 0.402 and 0.406 respectively,and the reproducibility Kappa value was 0.498.Conclusion the Tile classification has better reliability and reproducibility than the other two classifications in pelvic fracture,which is easy to master and apply.
