ObjectiveTo study the effect of immune formulation-assisted conventional therapy on anti-infective ability of multidrug-resistant Mycobacterium tuberculosis infection mice.MethodsBALB/c mice were used as experimental animals, multidrug-resistant M. tuberculosis infection models were built, randomly divided into model group, moxifloxacin group, thymopentin group and combined treatment group and given corresponding drug intervention, and then colony numbers in the spleen and lung, T lymphocyte subset contents and programmed death-1 (PD-1) expression levels in peripheral blood were detected.ResultsColony numbers in lung and spleen of moxifloxacin group and thymopentin group were significantly lower than those of model group and colony numbers in lung and spleen of combined treatment group were significantly lower than those of moxifloxacin group and thymopentin group; contents of CD3+CD4+T cells, Th1 and Th17 in peripheral blood of moxifloxacin group and thymopentin group were higher than those of model group, and contents of CD3+CD8+T cells, Th2 and Treg were lower than those of model group; contents of CD3+CD4+T cells, Th1 and Th17 in peripheral blood of combined treatment group were higher than those of moxifloxacin group and thymopentin group, and contents of CD3+CD8+T cells, Th2 and Treg were lower than those of moxifloxacin group and thymopentin group; PD-1 expression levels on T lymphocyte, B lymphocyte and monocyte surface in peripheral blood of moxifloxacin group and thymopentin group were lower than those of model group, and PD-1 expression levels on T lymphocyte, B lymphocyte and monocyte surface in peripheral blood of combined treatment group were lower than those of moxifloxacin group and thymopentin group.ConclusionsImmune formulation thymopentin can enhance the anti-infective ability of multidrug-resistant M. tuberculosis infection mice, decrease bacterial load in lung and spleen, and enhance immune function.
