ABSTRACT
Antisense oligonucleotide(ASON)has attracted a growing attention with the rapid development of biological tech?nology. ASON can be designed to target mRNA in a sequence-specific manner to stop,alter,or induce particular disease-related gene functions. Thus,its drugs have emerged as a very promising new class of therapeutics at the molecular genetic level with high specifici?ty and low toxicity. ASON has shown good application prospects in the treatment of brain diseases,by means of brain-targeted delivery and chemical modification. In this review,we summarize the latest development of ASON drugs and their applications on the treatment of Alzheimer disease,Parkinson′s disease and brain tumors.
ABSTRACT
Abstract?AIM: To analyze the clinical effects of partial rectus muscle transportation procedure for paralytic strabismus due to single rectus muscle paralysis.?METHODS:The conditions of 22 patients (25 eyes) who underwent partial rectus muscle transportation procedure for paralytic strabismus due to single rectus muscle paralysis were retrospectively reviewed. The following data were analyzed:1 ) the angle of deviation of primary position; 2 ) the presence of diploma in the primary position;3) the presence of compensatory head posture;4) the motility of the affected eye.All of the patients attended 6mo postoperative follow-up examinations.?RESULTS: According to the results of examinations before and during operation, different operations were performed:2 eyes were treated with partial rectus muscle transportation, 20 eyes were treated with recession of antagonistic muscle of paralytic rectus muscle combined with partial rectus muscle transportation, 3 eyes were treated with recession of antagonistic muscle, partial rectus muscle transportation and recession of yoke muscle.Twenty patients were orthotropia in the primary position, the diploma and abnormal head posture were eliminated. Two patients with binocular lateral rectus muscles paralysis were in mild undercorrection which were resolved by wearing 8△and 10△prisms respectively. The procedure improved strabismus of 25 eyes from 100.23△ ± 42.61△ preoperatively to 0.82△ ± 2.67△postoperatively ( t=10.797,P<0.001).Ocular movement was improved from -4.52 ±0.51 preoperatively to -2.68 ± 0.63 postoperatively (t=-19.468, P<0.001).? CONCLUSION: Partial rectus muscle transportation procedure for paralytic strabismus due to single rectus muscle paralysis can effectively correct the primary position in paralytic strabismus, eliminate the presence of diploma in primary position and abnormal head posture, and improve the ocular motility, which provides content clinical effects.
ABSTRACT
OBJECTIVE@#To investigate the characteristics of hypermetropic children whose visual acuity (VA) is declined or accompanied by esotropia.@*METHODS@#One hundred and ninety children were given optometry, strabismus degree and binocular vision measurement.@*RESULTS@#Declined VA appeared in 170 children, while esotropia occurred in 173. Sixty-one got binocular single vision, 17 had fusion function, and 11 had stereoaculty. Spherical equivalent had a linear relationship with VA (P 0.05). The influence factors of binocular vision were age of discovery, VA and the strabismus degree, while the stereoaculty was influenced by the strabismus degree, spherical equivalent and VA.@*CONCLUSION@#Low VA and strabismus are the most common complaint in children. Ametropia and strabismus do great harm to juvenile binocular vision, and stereoaculty is damaged seriously. We suggest an early examination of visual function in children.
