ABSTRACT
Object To enhance the initiative of the student from medical imaging specialty when studying medical imaging equipment to solve the problems in logic, abstractness, teaching contents, class hour and etc.Methods Distribution of theoretical and experimental lessons was considered comprehensively, and proper method was introduced into teaching difficult and key points.Results The initiative of the student was enhanced, and the teaching effectiveness was increased greatly.Conclusion References are provided to other courses in medical imaging specialty.
ABSTRACT
The implantation of posterior chamber phackic intraocular lens (PCPIOL) has been widely carried out worldwide,and its safety and efficacy have been well recognized.How to accurately choose the length of implantable collamer lens (ICL) in order to obtain the ideal vault and reduce postoperative complications,has been a research hotspot.This paper reviews related reports on the relationship between the length of ICL and its postoperative vault.
ABSTRACT
Posterior capsular opacification (PCO) is the most common complication that leads to loss of vision after cataract surgery.Neodymium doped:Yttrium-Aluminum-Garnet (Nd:Yag) laser capsulotomy is a common treatment for PCO, but still associated with several complications.In the past decades, the prevention and treatment of PCO have always been a hot spot of research in ophthalmology.This review will address the advances in the prevention and treatment of PCO in the aspects of surgical techniques and types of intraocular lens (IOL).
ABSTRACT
<p><b>OBJECTIVE</b>To investigate a patient featuring a complex neuromuscular disease phenotype.</p><p><b>METHODS</b>A comprehensive analysis integrating clinical investigation, electrophysiological testing, pathological analysis and mutation screening was carried out.</p><p><b>RESULTS</b>The patient has presented clinical and pathological manifestations mimicking Duchenne muscular dystrophy. However, genetic analysis has identified no deletion in 21 exons of Dystrophin gene, no pathologic expansion of CTG repeats in DMPK gene or CCTG repeats in ZFN9 gene. Instead, a homozygous deletion of exons 7 and 8 in SMN gene was discovered.</p><p><b>CONCLUSION</b>A rare case of spinal muscular atrophy (SMA) was verified by genetic diagnosis. SMA is a group of neuromuscular disorders with great phenotypic heterogeneity and sometimes cannot be diagnosed by clinical manifestations, electrophysiological and pathological changes alone. Genetic diagnosis has become indispensable for accurate diagnosis for patients suspected to have the disease.</p>
