ABSTRACT
Aim To study the protective effects of limb remote ischemic postconditioning ( LRIP ) on is-chemic stroke rats under hyperglycemia and explore the mechanisms. Methods Rats were given 50% glucose (6 mL·kg-1 ) by intraperitoneal injection to get acute hyperglycemia model. Then middle cerebral artery oc-clusion ( MCAO) models were created. After blocking middle artery for 1. 5 h and reperfusion for 2 h, behav-ioral testing, infarct size of brain, NO concentration and SOD activity in the serum of those rats were detec- ted. Results LRIP could improve behavioral score, decrease the area of cerebral infarction, increase the concentration of NO and the SOD activity in serum of MCAO rats. Conclusion LRIP can relieve cerebral ischemia-reperfusion injury of MCAO rats under acute hyperglycemia.
ABSTRACT
objective To explore a reasonable treatment for upper eyelid shrinking. Methods All 15 patients with upper eyelid retrac-tion were divided in group A,group B and group C. Group A with 9 eyes received botulinum toxin type A,group B with 10 eyes were corrected by central aponeurosis disinsertion,group C with 9 eyes upper eyelid were corrected by the lengthening of the levator muscle and Müller's muscle. And the data was summarized and analyzed. Results Five cases (9 eyes) with upper eyelid shrinking obviously were improved 72 h after injecting botulinum toxin type A,but the eyelids returned to previous states 4~6 months later. The shape of postoperative eyelid was good and the eyelids structure was natural in group B,recurrence was in 2 cases. Patients in group C had satisfactory results. And there was no recurrence and complications after 3~24 months of follow-up. Conclusion The three treatments have effect on upper eyelid shrinking at quiescence phase. The method of injecting botulinum toxin type A is simple,with reliable curative effect and short duration,while it was nee-ded repeated injections. The method of central aponeurosis disinsertion is simple but difficult to quantify properly. The lengthening of the leva-tor muscle is not only simple but also with reliable effect and less complications.
