| 摘要: |
| 目的 研究Omega-3多不饱和脂肪酸对痤疮动物模型金黄地鼠皮脂腺斑的影响及相关机制。方法 24只金黄地鼠随机分为4组，每组6只：空白组、低剂量鱼油组、高剂量鱼油组、异维A酸阳性对照组，连续灌胃4周，观察金黄地鼠皮脂腺斑大小、组织病理结构、磷脂酰肌醇3-激酶（phosphatidyl inositol 3-kinase，PI3K）以及蛋白激酶B（protein kinase B，AKT）蛋白表达水平。结果 干预后，与空白组相比，低剂量鱼油组、高剂量鱼油组、异维A酸阳性对照组皮脂腺斑面积均减小，差异具有统计学意义（P<0.05）；低剂量鱼油组、高剂量鱼油组和异维A酸阳性对照组皮脂腺斑组织大小减小、重叠腺叶数减少、排列较空白组疏松；低剂量鱼油组、高剂量鱼油组、异维A酸阳性对照组AKT及PI3K表达水平均比空白组低，差异具有统计学意义（P<0.05）。结论 Omega-3多不饱和脂肪酸通过PI3K/AKT通路改善皮脂腺增生、调节皮脂分泌。 |

| Abstract: |
| Objective To study the effect of Omega-3 polyunsaturated fatty acids on the sebaceous spots in golden hamster with acne and its related mechanism. Methods 24 golden hamsters were randomly divided into 4 groups, with 6 in each group: blank group, low-dose fish oil group, high-dose fish oil group, isotretinoin positive control group. The expression levels of PI3K and Akt, pathological structure and sebaceous plaque size of golden hamsters were observed by continuous intragastry for 4 weeks. Results After intervention, compared with blank group, the area of sebaceous glands in low-dose fish oil group, high-dose fish oil group and isotretinoin positive control group were smaller, the difference was statistically significant (P<0.05); the size of sebaceous plaque tissue in low-dose fish oil group, high-dose fish oil group and isotretinoin positive control group decreased and the number of overlapping gland lobes decreased, and the arrangement was looser than that in blank group. The expression levels of AKT and PI3K in low-dose fish oil group, high-dose fish oil group and isotretinoin positive control group were lower than those in blank group, and the differences were statistically significant (P<0.05). Conclusion Omega-3 polyunsaturated fatty acids can improve sebaceous gland hyperplasia and regulate sebum secretion through PI3K/AKT pathway. |
