Due to the serious shortage of donor cornea materials and the donor limit, clinical popularization of penetrating keratoplasty is severely restricted. lt is a hot spot of current research that applying tissue engineering in vitro to culture corneal endothelial cells ( CEC ) with high density, regular hexagonal shape and healthy endothelial function. ln this article, we reviewed the latest progress in the study of source of CEC seeder cells, selection of cultivating carries, type of CEC transplantation and immune mechanism that summarized the current research problems and made a prospect to the future.

There are more prognostic factors affecting the patients with cerebral hemorrhage, including bleeding volume, bleeding site, cause of bleeding, and blood pressure regulation during acute phase. Among them, the regulation of blood pressure during acute phase is a man-controlled important factor. However, the ideal blood pressure level has not yet to he determined at present. Therefore, more clinical trials are needed to determine the exact time window of blood pressure management in patients with intracerebral hemorrhage during acute phase and the range of blood pressure control.

[Abstract ] Objective Explore the clinical pathological characteristics and diagnostic methods on ent mucous epidermoid carcinoma.Methods Collection of 20 cases with ent mucous epidermoid carcinoma in our hospital,using immunohistochemical method to detect patients with CK and EMA,CEA and CK8 ex-pression.Results Twenty patients were men,of which the high differentiation of 17 cases,3 cases of poorly differentiated.CK ,EMA and CEA in patients with tumor tissue and CK8 were positive expression. Conclusions Ent mucous epidermoid carcinoma is a kind of relatively rare ent tumor,its clinical patholog-ical features and tumor tissue in CK and EMA,CEA and CK8 expressed help to identify and diagnosis.

OBJECTIVE:The bioassay and HPLC methods were established and compared for the determination of levofloxacin(Lev) in human plasma.METHOD:In bioassay,medium Ⅱ and staphylococcus aureus were used.The HPLC method was chromatographed with a mobile phase of methanol-0.02mol/L potassium dihydrogen phosphate solution (3∶7)，the sample was treated by adding 30% trichloroacetic acid to precipitate protein,and detected at 276mm.RESULTS:The average recovery of bioassay was within 95.90%～106.68%,the within-day and day-to-day precisions were below 6%.The average recovery of HPLC was within 97.24%～101.70%,the within day and day-to-day precisions were blow 5%.Lev tablets were given to 6 patients in two ways.Drug concentrations in plasma were determined by bioassay and HPLC assay,respectively,with no significant difference (P＞0.05).CONCLUSION:The bioassay was simple,cheap,time saving,and reliable.The HPLC method wsa rapid,sensitive,accurate.The two methods may be selected to use in actual conditions.
