With the increasing perfection and improvement of microsurgery technique in modern ophthalmology, especially the popularization of micro-incision cataract extraction and the rise of femtosecond-laser-assisted cataract extraction, the cataract extraction and intraocular lens implantation is gradually transformed from vision rehabilitation surgery into refractive surgery and people also pursue better postoperative visual experiences. However, the preoperative and postoperative corneal astigmatism is always the main factor affecting the postoperative visual effect. ln recent years, the development of design and materials of the intraocular lens ( lOL) provided necessary basic conditions for clinical application of the Toric lOL. The Toric lOL is primarily characterized by effective correction of cataract patients′postoperative corneal astigmatism, which results in the enhancement of patients′postoperative visual function. ln this paper, the design, classification and clinical application of Toric lOL were analyzed, and current problems and prospect were discussed.

Objective To study changes in expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA in the kidney and spleen of dead rats and its application in deducing the postmortem intervals (PMI), so as to look for a new method for PMI deduction. Method 28 rats were killed by cervical dislocation, placed in a chamber with temperature-controlling system at 20℃ for 0 to 48h postmortem, and autopsied at 0, 8, 16, 24, 32, 40 and 48h respectively (n=4 for each time point). The expression of GAPDH mRNA in kidney and spleen was assessed with fluorescence semi-quantitative RT-PCR. Results The amplified products of GAPDH mRNA could be detected in kidney within 40h and in spleen within 32h postmortem respectively, and they showed a decreasing tendency as its fluorescence intensity declined gradually and lost at last. Conclusion Detection of GAPDH mRNA expression in kidney and spleen of rats at different periods after death by fluorescence semi-quantitative RT-PCR seems to be of some value for estimation of PMI.

BACKGROUND:Anterior cruciate ligament (ACL) has been reported to hold a self-recovery potential, which may be related to certain cytokines and biological factors, such as stem cells or progenitor cells.OBJECTIVE: To review the literatures about the relationship between mesenchymal stem cells and ACL injuries, and understand the potential of stem cells or progenitor cells differentiating into ACL, thus providing a basis for the clinical use of mesenchymal stem cells in the treatment of ACL injury. METHODS:A computer-based online research of PubMed databases was performed to collect articles including reviews, clinical trials and basic studies using the English keywords of ACL regeneration, stem/progenitor cells, mesenchymal stem cells. Forty-five eligible articles were included finally. RESULTS AND CONCLUSION:In recent years, there are a lot of studies addressing the treatment of ACL injuries and muscle/bone regeneration, but the use of stem cells is still far from the clinical requirements. The source of stem cells suitable for the ACL regeneration and their most suitable injection points are under discussion. Although the mesenchymal stem cells have been reported to successfully repair ACL injury in animal models, either trophic factors of stem cells or these cells themselves improving the regeneration remains unclear.
