Application of menisci reformation and repair in the treatment of the discoid meniscus injuries / 中国骨伤

<p><b>OBJECTIVE</b>To study the clinical effects of menisci reformation and repair for the treatment of discoid meniscus injuries and to explore the operation methods.</p><p><b>METHODS</b>From Jun. 2005 to Dem. 2009, 28 patients underwent arthroscopic menisci reformation and repair for discoid meniscus, including 23 males and 5 females, ranging in age from 6 to 42 years, with an average of 32 years. The nature of meniscus and the type and range of tear were judged under arthroscope. The menisci reformation and repair were used to treat discoid meniscus tear at the edge. After the operation, the brace was used for 8 weeks, and heavy exercise should be avoided for 6 months. The Lysholm score was adopted to evaluate therapeutic effects.</p><p><b>RESULTS</b>All the patients were followed up ranging from 3 to 36 months, averaged 8 months. The preoperative Lysholm scores ranged from 62 to 74, with a mean of (67.23 +/- 5.24), and the postoperative Lysholm scores ranged from 80 to 96, with a mean of (87.24 +/- 5.26). There was no occurrence of re-tear or re-operation due to symptom recurrence.</p><p><b>CONCLUSION</b>The menisci reformation and repair has better clinical effects on the treatment of discoid meniscus tear and can be regarded as one of the operational options.</p>

The experiment of porcine keratinocytes cultured on porcine small intestinal submucosa in vitro / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility of acellular porcine small intestinal submucosa (SIS as bioscaffold of tissue engineering skin.</p><p><b>METHODS</b>The second passage keratinocytes were seeded on SIS, after seeded for 11, 13, 15, 17 days, the keratinocytes/SIS composites were observed by dye directly, histopathology, immunohistochemical studies with monoclonal antibodies against laminin and transmission electron microscope (TEM).</p><p><b>RESULTS</b>At eleventh day, keratinocytes were growth very well on the surface of SIS, there are 2-3 cell layers on partial of the SIS surface, the continued expression of laminin can be detected between the keratinocytes and the surface of SIS. After 13, 15, 17 days this stratified structure increased, cells contact more closely, the tonofibrils in cells, desmosome between cells and the basal membrane between the keratinocytes and the surface of SIS can be seen with TEM.</p><p><b>CONCLUSIONS</b>SIS is a kind of good bioscaffold in the culture of porcine keratinocytes in vitro.</p>

Clinical analysis of complications during manual small incision cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

· AIM: To discuss the cause and management of complications during the manual small incision cataract surgery (MSICS).combined with intraocular lens implant (MSICS-IOL) were done in 160 patietns with cataract. In this paper, we reviewed the clinical data of the intraoperative complications.injury, posterior capsule rupture, iris prolapse and hyphema, were mainly caused by inexpert skill and lacking of experience.techniques, careful operation could decrease the incidence of complications during MSICS operation. By proper management, the intraoperative complications could be solved satisfactorily.
