- Abstract: Objective To duplicate the existing model of intracranial oculomotor nerve injury in rats,and propose a new method of orbital cavity clamping oculomotor nerve,evaluate the respective advantages of the two models.Methods Male SD rats were used as experimental animals,and two different methods of preparing oculomotor nerve injury models were compared.Sphenopalatine foramen approach group:clamp the initial segment of the oculomotor nerve from the opening of the upper edge of the orbit for 10 s.The skull base approach group,the temporal bone was removed and the infratentorial segment of the oculomotor nerve was clampped for 10 s.Taking the success rate,survival rate and survival status of the model rats as observation indicators,the applicability of the model rats to the intervention of gastric perfusion was and intraorbital electroacupuncture evaluated.Results The success rate after molding 24 h:In the sphenopalatine foramen approach group was 92.31%(12/13);In the skull base approach group was 34.29%(12/35).Survival rate:7 d after gavage:In the sphenopalatine foramen approach group,6 patients survived,with a survival rate of 100.00%(6/6).Four patients survived in the skull base approach group,with a survival rate of 66.67%(4/6).7 days after orbital electroacupuncture:Five patients survived in the sphenopalatine foramen approach group(83.33%,5/6).Three patients survived in the skull base approach group,with a survival rate of 50.00%(3/6).Survival state of rats(0-20 points,the smaller the score,the better):24 h after modeling,the status score of sphenopalatine foramina approach group was 4.11±0.90,and that of skull base approach group was 12.39±1.378.After 7 days of intragastric administration,the score of sphenopalatine foramina approach group was 2.50±1.05,and the score of skull base approach group was 14.50±0.58.The score of sphenopalatine foramina approach group was 2.00±1.22 and the score of skull base approach group was 15.33±0.58 after 7 days of intraorbital electroacupuncture intervention.The success rate,survival rate and survival state of rats in sphenopalatine foramina approach group were better than those in skull base approach group 24 h after modeling(P<0.05);The survival rate and survival state of rats in sphenopalatine foramina approach group were better than those in skull base approach group 7 days after gavage and orbital electroacupuncture intervention(P<0.05).Conclusion The model of oculomotor nerve injury prepared by sphenopalatine foramina approach is more suitable for the basic research of nerve repair after the intervention of gastric gavage and orbital electroacupuncture.The model rats with oculomotor nerve injury prepared by the base approach are more suitable for the basic research after the injury of the intracranial segment of the oculomotor nerve.
