摘  要:目的探讨小剂量红霉素对气管损伤后肉芽组织增生的影响。方法将42只家兔按随机数字表法分成A~G共7组各6只;其中A为空白对照组,B为青霉素组,C为红霉素组,D为红霉素+青霉素组,E为布地奈德组,F为红霉素+布地奈德组,G为红霉素+布地奈德+青霉素组。42只家兔行气管切开后均予尼龙毛刷来回刷20次进行造模。术前1周至术后第9天各组分别予上述药物处理。术后第10天采集血液标本检测转化生长因子β1(TGF-β1)、血管内皮生长因子(VEGF)、白细胞介素(IL)-6、IL-8浓度;并进行气管狭窄度测量。结果A~G组血清中TGF-β1浓度分别为(17.6±1.3)、(18.2±3.1)、(13.0±1.1)、(14.0±1.0)、(21.0±6.1)、(13.6±3.5)、(8.2±1.3)ng/L,VEGF浓度分别为(88.1±4.1)、(85.8±4.3)、(58.1±6.3)、(56.5±2.4)、(87.8±2.8)、(57.0±3.7)、(34.3±6.7)ng/L, IL-6浓度分别为(67.8±4.0)、(66.1±3.5)、(54.1±4.8)、(52.1±3.2)、(64.6±4.9)、(49.4±4.2)、(35.9±3.7)ng/L,IL-8浓度分别为(112.8±5.2)、(116.6±4.1)、(88.0±6.2)、(85.5±3.5)、(114.4±4.6)、(82.6±3.8)、(55.9±6.0)ng/L;C、D、F、G组血清中TGF-β1、VEGF、IL-6、IL-8浓度均显著低于A、B、E组(均P〈0.05),G组浓度均显著低于其他各组(均P〈0.05)。42只家兔气管内均有不同程度的肉芽组织增生致气管狭窄。A~G组气管狭窄度分别为(53.3±4.4)%、(48.2±5.0)%、(24.3±4.4)%、(29.5±3.2)%、(47.8±6.5)%、(27.9±3.1)%、(15.6±2.0)%,C、D、F、G组狭窄度均显著轻于A、B、E组(均P〈0.05),G组狭窄度均显著轻于其他各组(均P〈0.05)。结论小剂量红霉素能有效抑制气管损伤后肉芽组织的增生,与其他抗菌素及糖皮质激素联合用药效果更佳。ObjectiveTo investigate the effect of low dose erythromycin on the proliferation of granulation tissue after tracheal injury.MethodsForty-two rabbits were randomly divided into 7 groups (n=6 each), group A (saline control group), group B (penicillin group), group C (low dose erythromycin group), group D (low dose erythromycin and penicillin group), group E (budesonide group), group F (low dose erythromycin and budesonide group), group G (low dose erythromycin, penicillin and budesonide group). All rabbits received tracheotomy, and the tracheal mucosa was scraped with a nylon brush 20 times for tracheal stenosis model. Rabbits were treated with corresponding drugs from a week before operation to 9 days after operation. The serum concentrations of transforming growth factor - beta 1 (TGF-β1), vascular endothelial growth factor (VEGF), interleukin (IL) -6, IL-8 were determined and the tracheal specimens were harvested for measuring degree of stenosis on the 10th day after operation.ResultsSerum concentrations of TGF-β1 in group A, B, C, D, E, F and G were (17.6±1.3), (18.2±3.1), (13.0±1.1), (14.0±1.0), (21.0±6.1), (13.6± 3.5), (8.2±1.3) ng/L; VEGF were (88.1±4.1), (85.8±4.3), (58.1±6.3), (56.5±2.4), (87.8±2.8), (57.0±3.7), (34.3±6.7) ng/L; IL-6 were (67.8±4.0), (66.1±3.5), (54.1±4.8), (52.1±3.2), (64.6±4.9), (49.4±4.2), (35.9±3.7) ng/L; IL-8 were (112.8±5.2), (116.6±4.1), (88.0±6.2), (85.5±3.5), (114.4±4.6), (82.6±3.8), (55.9±6.0) ng/L, respectively. The serum concentrations of TGF-β1, VEGF, IL-6 and IL-8 in group C, D, F and G were significantly lower than those in group A, B and E (all P〈0.05). Compared with the other groups, the serum concentrations in group G were the lowest (all P〈0.05). All 42 rabbits had tracheal stenosis with different degrees of proliferation of granulation tissue. The degree of tracheal stenosi
