Effects of electroacupuncture at Hegu(LI4)on refractive parameters and the expression of TNF-α and IL-1β in retinal tissue of mice with form-deprivation myopia
摘要
Abstract
Objective To observe the effects of electroacupuncture at the Hegu(LI4)acupoint on refractive parame-ters and the expression of tumor necrosis factor-α(TNF-α)and interleukin-1 β(IL-1β)in the retinal tissue of mice with form-deprivation myopia(FDM).Methods Forty-eight SPF-grade,3-week-old healthy male C57BL/6J mice were ran-domly divided into four groups:normal control group,FDM group,sham acupuncture group,and Hegu group.Experimen-tal myopia was induced in the right eyes of mice in the latter three groups by wearing translucent diffuser goggles.Mice in the Hegu group received electroacupuncture stimulation at the Hegu(LI4)acupoint,while those in the sham acupuncture group received intervention with a non-penetrating blunt needle at the same location.Body weight,refractive error,and axial length were recorded for all mice before modeling and at 2 and 4 weeks after modeling.At 4 weeks post-modeling,mice were euthanized.Real-time quantitative PCR(RT-qPCR)and Western blot were used to detect the mRNA and protein expression levels of TNF-α and IL-1β,respectively,in the right retinal tissues.Retinal cell apoptosis was assessed by TUNEL staining.Results At 2 weeks post-modeling,compared with the normal control group,the refractive error of the right eyes was significantly decreased and the axial length was significantly increased in the FDM,sham acupuncture,and Hegu groups(all P＜0.01).At 4 weeks post-modeling,compared with the normal control group,the refractive error was significantly decreased and the axial length was significantly increased in the FDM and sham acupuncture groups(all P＜0.001).Compared with both the FDM and sham acupuncture groups,the Hegu group showed a significant increase in re-fractive error and a significant decrease in axial length(all P＜0.001).At 4 weeks post-modeling,RT-qPCR and Western blot results showed that the mRNA and protein expression levels of TNF-α and IL-1 β in the retina were significantly higher in the FDM and sham acupuncture groups compared to the normal control group(all P＜0.05).In contrast,the protein ex-pression level of TNF-α and the relative mRNA and protein expression levels of IL-1β in the Hegu group were significantly lower than those in the FDM group(all P＜0.05).TUNEL staining results showed that the retinal cell apoptosis rate was significantly higher in the FDM and sham acupuncture groups compared to the normal control group(all P＜0.001).Com-pared with the FDM and sham acupuncture groups,the retinal cell apoptosis rate was significantly lower in the Hegu group(all P＜0.001).Conclusion Electroacupuncture at the Hegu(LI4)acupoint can significantly inhibit the progression of myopia in mice.The mechanism may be related to the downregulation of TNF-α and IL-1β expression in the retinal tissue,thereby inhibiting retinal cell apoptosis.关键词
