Efficacy observation on electroacupuncture in the treatment of oculomotor impairment caused by ophthalmic nerve injury / 中国针灸

<p><b>OBJECTIVE</b>To observe the difference in the clinical efficacy on oculomotor impairment between electroacupuncture and acupuncture and explore the best therapeutic method in the treatment of this disease.</p><p><b>METHODS</b>Sixty cases of oculomotor impairment were randomized into an electroacupuncture group and an acupuncture group, 30 cases in each one. In the electroacupuncture group, the points were selected on extraocular muscles, the internal needling technique in the eye was used in combination of electroacupuncture therapy. In the acupuncture group, the points and needling technique were same as the electroacupuncture group, but without electric stimulation applied. The treatment was given 5 times a week, 15 treatments made one session. After 3 sessions of treatment, the clinical efficacy, palpebral fissure size, pupil size, oculomotor range and the recovery in diplopia were compared before and after treatment in the two groups.</p><p><b>RESULTS</b>In the electroacupuncture group, the palpebral fissure size was (9.79+/-2.65)mm and the eyeball shifting distance was (18.12+/-1. 30)mm, which were hig-her than (8.23+/-2.74)mm and (16.71+/-1. 44)mm respectively in the acupuncture group. In the electroacupuncture group, the pupil diameter was (0. 44 +/-0. 42)mm, which was less than (0. 72 +/- 0. 53)mm in the acupuncture group, indicating the significant difference (all P<0. 05). The cured rate was 63. 33% (19/30) and the total effective rate was 93.33% (28/30) in the electroacupuncture group, which was better than 36.67% (11/30) and 83. 333 (25/30) in the acupuncture group separately, indicating the significant difference (all P<0. 05).</p><p><b>CONCLUSION</b>Electroacupuncture presents the obvious advantages in the treatment of oculomotor impairment, characterized as quick and high effect, short duration of treatment and remarkable improvements in clinical symptoms, there are important significance for the improvement of survival quality of patients.</p>

Role of CD4+CD25+T cells in experimental autoimmune uveoretinitis / 中华实验眼科杂志

Background Experimental autoimmune uveoretinitis(EAU)is proved to be an organ-specific,T lymphocyte-mediated autoimmune and self-limited disease.Research showed that CD4+CD25+T cell may play important regulation on the course of events,but its mechanism is pending for further study. Objective Present study was to investigate the potential role of CD4+CD25+T cell in the pathogenesis of EAU. Methods Retinal Santigen(S-Ag)was isolated from bovine retinas according tO the procedure as Caspi's previously describe.0.1 ml Santigen(50μg)emulsified with complete Freund'S adjuvant was injected on footpad of 24 inbred adult female Lewis rats aged six to eight-week-old to induce EAU,and 4 normal Lewis rats were as normal control group.Slim-lamp examination was performed to observe the ocular manifestation.Retinal section was prepared in 7,12,15,21 days aher injection for the pathological examination.The pathological grading was on the lnoki'S method.The retinas,inguinal nodes and spleens of rats were obtained in 7,12,15,21 days after injection and the cellular suspension was prepared.Expression of CD4+CD25+T cells on cellular suspension was assayed using flow eytometry.This study complied with the Standard of Association for Research in Vision and Ophthalmology. ResuRs The obvious inflammatory response of the anterior segment was found in S-Ag injected eyes from 7 days through 21 days.The most serious inflammation was found in 12-15 days under the slim-lamp.The hemotoxylin and eosin staining showed the higher pathological grading from 12 to 15 days after injection,showing significant difference in comparison with 7 days and 14 days(P=0.000).In EAU model rats,expressions of CD4+CD25+T cells was significantly increased in retinas, inguinal nodes and spleens in 15 days after injection,showing evidently differences in comparison with control rats(P=0.000). Conclusion The expression level of CD4+CD25+T cells in inflammatory tissue is associated with the inflammation procedure in EAU model rats.This study indicates that CD4+CD25+T cells may play a role in the development of EAU.
