Changes of TNF-α, IL-10, red blood cell, and white blood cell count of the three groups of rats.

Group	No. of animals	TNF-α	IL-10	Red blood cell count	White blood cell count
Control group	15	117.86 ± 77.20	1265.00 ± 496.31	3.6 ± 1.65	76.4 ± 9.50
ALI group and	15	1029.24 ± 173.61∗	224.42 ± 135.79∗	3638.3 ± 318.42∗	183.9 ± 11.45∗
ALI + KGF-2 group	15	531.48 ± 134.16∗∗	960.71 ± 310.96∗∗	2452.2 ± 255.49∗∗	159.2 ± 13.10∗∗

Note. TNF-α is tumor necrosis factor-α. IL-10 is interleukin-10. TNF-α and IL-10 were used to detect lung tissue homogenate, using enzyme-linked immunosorbent assay. Red blood cell and white blood cell count detection of bronchoalveolar lavage fluid. Compared with control group, ^∗P < 0.01; compared with ALI model group, ^∗∗P < 0.01.
