目的
2
本研究观察龙牡皮炎方对2,4-二硝基氯苯(DNCB)诱导特应性皮炎(AD)的BALB/c小鼠模型氧化应激的干预作用并探讨其机制。
方法
2
采用BALB/c小鼠背部皮肤DNCB致敏的方法建立AD模型。雄性BALB/c小鼠40只,随机分为空白组、模型组、维生素C组(0.5×10
-3
g·kg
-1
)及龙牡皮炎方组(26 g·kg
-1
)。除空白组外,模型组、维生素C组和龙牡皮炎方组小鼠分别采用背部外涂不同浓度DNCB致敏的方法诱导AD,空白组予基质外涂。分别于2% DNCB致敏后7 d及0.2% DNCB致敏后24 d开始灌胃给药,连续21 d。实验结束后直接观察各组小鼠皮损变化;采用酶联免疫吸附测定法(ELISA)检测各组小鼠血清中白细胞介素(IL)-4,肿瘤坏死因子(TNF)-
α
、免疫球蛋白E(IgE)、活性氧(ROS)的水平;总抗氧化能力测定试剂盒-微量法(ABTS法)测定血清抗氧化能力(TAOC)的水平;采用苏木素-伊红(HE)染色观察皮损部位病理形态学改变;免疫组化法检测皮损部位胸腺基质淋巴细胞生成素(TSLP)表达;蛋白免疫印迹法(Western blot)检测背部皮损部位丝聚蛋白(FLG)的表达。
结果
2
与空白组比较,模型组小鼠皮损评分显著增高(
P
<
0.01),HE染色显示皮肤损伤部位出现AD的特征性病理改变,同时皮损处TSLP表达明显增加及FLG表达降低(
P
<
0.05);血清中TNF-
α
、IL-4、IgE、ROS含量升高,同时TAOC活性下降(
P
<
0.01)。与模型组比较,龙牡皮炎方组小鼠皮损评分显著下降,皮损病理明显改善;同时皮损组织中TSLP表达降低及FLG表达上升(
P
<
0.05);此外龙牡皮炎方组小鼠血清中TNF-
α
、IL-4、IgE和ROS含量相比模型组也有不同程度降低(
P
<
0.05,
P
<
0.01),且TAOC活性上升(
P
<
0.01)。
结论
2
AD氧化应激程度与皮损严重程度、细胞炎症因子水平具有明显的关联性。龙牡皮炎方可通过促进ROS清除,提升TAOC而抑制氧化应激,从而改善BALB/c小鼠AD样皮损,保护皮肤屏障,降低炎症反应。
Objective
2
This study observes the intervention effect of Longmu Piyan prescription on oxidative stress in BALB/c mice with atopic dermatitis (AD) induced by 2,4-dinitrochlorobenzene (DNCB) and explores its mechanism.
Method
2
The AD model was established using the method of DNCB sensitization on the back skin of BALB/c mice. Forty male BALB/c mice were randomly divided into a blank group, a model group, a vitamin C control group (0.5×10
-3
mg·kg
-1
), and a Longmu Piyan prescription group (26 g·kg
-1
). Except for the blank group, other groups were sensitized with different concentrations of DNCB on the back to induce AD, and the blank group was treated with matrix coating. The gastric administration was started on the seventh day after sensitization with 2% DNCB and on the 24th day after sensitization with 0.2% DNCB continuously for 21 days. The changes in skin lesions of each group were directly observed after the experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin (IL)-4, tumor necrosis factor (TNF)-
α
, immunoglobulin E (IgE), and reactive oxygen species (ROS) in the serum of each group. The total antioxidant capacity determination kit-trace method (ABTS method) was used to measure the level of total antioxidant capacity (TAOC) in serum. The Hematoxylin eosin (HE) staining method was used to observe the pathological and morphological changes of the skin lesion site. The immunohistochemical method was used to detect the expression of thymic stromal lymphopoietin (TSLP) in the skin lesion site. Western blot was used to detect the expression of filaggrin (FLG) in the dorsal skin lesions.
Result
2
The results showed that compared with the blank group, the skin lesion score of the model group mice was significantly increased (
P
<
0.01), and HE staining showed characteristic pathological changes of AD in the skin lesion site. At the same time, the expression of TSLP in the skin lesion was significantly increased, and that of FLG was reduced (
P
<
0.05). The levels of TNF-
α
, IL-4, IgE, and ROS in serum increased, while the activity of TAOC decreased (
P
<
0.01). Compared with the model group, the Longmu Piyan prescription group showed a significant decrease in skin lesion scores and a significant improvement in skin lesion pathology. At the same time, the expression of TSLP decreased, and the expression of FLG increased in the skin lesions (
P
<
0.05). In addition, compared with the model group, the serum levels of TNF-
α
, IL-4, IgE, and ROS also decreased to varying degrees (
P
<
0.05,
P
<
0.01), and TAOC activity increased in the Longmu Piyan prescription group (
P
<
0.01).
Conclusion
2
There is a significant correlation among the degree of oxidative stress, the severity of skin lesions in AD, and the levels of inflammatory cytokines. Longmu Piyandu prescription can improve AD-like skin lesions in BALB/c mice by promoting ROS clearance, enhancing TAOC, and inhibiting oxidative stress, thus protecting the skin barrier and reducing inflammation.
