目的：观察中药超微粉腧穴敷贴对变应性鼻炎大鼠鼻黏膜重塑的影响。方法：40只SD大鼠随机分为对照组（D组）和造模组，造模组予卵蛋白腹腔注射、滴鼻及喷雾吸入，造模成功后随机分为空白组（A组）、丙酸氟替卡松组（B组）和超微粉组（C组）。记录鼻黏膜嗜酸性粒细胞（EOS）计数、HE染色及电镜观察结果。结果：（1）与D组相比，A组EOS计数升高（P＜0．01），HE染色示黏膜上皮肿胀，毛细血管扩张，EOS浸润，电镜示黏膜不完整，纤毛、微绒毛畸形稀松，线粒体肿胀，部分线粒体脊丢失；（2）EOS计数：B、C组较A组显著下降（P＜0．05，P＜0．01）。 C组较B组显著下降（P＜0．05），与D组比较无统计学差异（P＝0．539）；HE染色：B组黏膜毛细血管轻微扩张，散见EOS，C组黏膜上皮轻微肿胀，无毛细血管扩张；电镜：B、C组黏膜完整，纤毛等结构排列均匀，细胞连接正常，C组还可见正常线粒体及内质网。结论：中药超微粉腧穴敷贴可有效控制变应性鼻炎症状，减缓甚至逆转鼻黏膜重塑。%Objective To observe the effect of ultrafine herb moxibustion on nasal mucosal remodeling in rats with allergic rhinitis. Methods Forty SD rats were randomly divided into control group (Group D) and modeling group. When successfully induced by intraperitoneal injection, aerosol inhalation and nasal spray of ovalbumin, the modeling group were randomly subdivided into modeling group (Group A), fluticasone propionate group (Group B) and ultrafine herb moxibustion group (Group C). Comparisons were made between the groups in respect of HE staining, transmission electron microscopy and counts of EOS. Results (1) Compared with Group D, Group A had significant elevation in counts of EOS (P<0.01);mucosal epithelium swelling, apparent angiotelectasis and eosinophilic infiltrated by HE staining; incomplete mucosal surface with deformity cilia, swelling mitochondria and partial loss of the mitochondria ridge by TEM . ( 2 ) Counts of EOS in Groups B and C were significantly decreased than in Group A (P<0.05, and P<0.01). Those in Group C were significantly decreased than in Group B (P<0.05), and there was insignificant difference in the counts between Group C and Group D (P=0.539). The HE staining Group B showed mild telangiectasia, with EOS scattered. The HE staining in Group C showed epithelial minor swelling and no telangiectasia. TEM showed mucosal surfaces in Groups B and C were complete, the quantity of cilia and microvillus increased apparently and cell junctions were normal. Normal endoplasmic reticulum and mitochondria were evident in Group C. Conclusion The ultrafine herb moxibustion can relieve the clinical symptoms, slow down and even reverse the nasal mucosal remodeling.
