The aim of this study was to investigate the feasibility of anterior segment optical coherence tomography to assess the anterior segment morphology of hyperopia in school-aged children. 320 eyes of 160 school-aged children, 6-12 years of age, were examined with anterior segment optical coherence tomography and were divided into four groups according to the cycloplegic spherical equivalence of refractive error. The mentioned four groups were: emmetropia group, low hyperopia group, moderate hyperopia group and high hyperopia group. The measurements of central corneal thickness, anterior chamber depth, angle opening distance, trabecular iris space area and scleral angle were compared in pairs among objects in the four groups. The results showed that high hyperopia and moderate hyperopia had shallower anterior chamber depth and narrower anterior chamber angle compared to those in emmetropia group. The study also showed that anterior segment optical coherence tomography as a non-contact technology could become a new technology for accessing the anterior segment morphology of hyperopia in school-aged children.

BACKGROUND: Membrane materials of bioreactor have exchange of substance and good physiochemical characteristics as well as good biocompatibility.OBJECTIVE: To evaluate the biocompatibility of interface of human hepatocyte/microporous polypropylene, i.e. graft modified microporous polypropylene semipermeable ultrafiltration membrane (MPP).DESIGN, TIME AND SETTING: Animal observation was performed at the Organ Transplantation Center, Ruijin Hospital of Shanghai Jiao Tong University Medical School and Polymers Institute of Zhejiang University between September 2005 and October 2007.MATERIALS: The microporous polypropylene ultrafiltration plane thin membranes, 0.2 μm diameter, M<,r> 50 000-100 000 molecular blockage, were used. Photochemical graft polymerization modification technique was adopted to graft hydrophilic acrylamide group through chemical bonds on MPP surface and succeeded in constructing an interface of human hepatocyte/microporous polypropylene, i.e. bioreactor membrane of bioartificial liver, graft modified MPP.METHODS: The biocompatibility of modified MPP was evaluated by hemolysis test, cytotoxicity test, acute systemic toxicity test, pyrogen test, skin sensitization and percutaneous stimulation test according to the requirements and biological evaluation criteria of medical device of ISO10993-1:1992.MAIN OUTCOME MEAURES: The experimental results of hemolysis, cytotoxicity, general acute toxicity, pyrogen, skin sensitization and percutaneous stimulation of modified MPP.RESULTS: The hemolytic rate of modified MPP was 1.90% (<5%), which showed that modified MPP did not lead to hemolysis. The extract solution of modified MPP exhibited no significant inhibition on the proliferative activity of L929 cells. At 24, 48 and 72 hours after MPP injection, no mice death, significant changes in body mass, or acute systemic toxicity were observed, such as ptosis, dyspnea, eyanosis, abdominal stimulation, diarrhea, decreased movement or tremor. In rabbit pyrogen test, the body temperature changed in a range from -0.2 to 0.4, which was consistent with the evaluation criteria of biomedical materials without pyrogen. Only one case was found with very slight erythema in skin sensitization test; its integral was 1 and primary stimulation index was 0.25 (<0.4), and the primary stimulation index of percutaneous stimulation test was 0.2; the average primary stimulation index was 0.068, indicating that modified MPP had no skin irritation.CONCLUSION: Modified MPP has no haemolytieus, cytotoxicity, pyrogenicity or skin sensitization, suggesting good biocompatibility by photochemical graft acrylamide on the surface of MPP.

Hepatocyte transplantation may be a viable alternative treatment to liver transplantation for acute/chronic liver failure and metabolic liver disorders. Hepatocyte transplantation is an effective treatment to support liver function around liver transplantation due to its relatively easy manipulation and mild wound. In recent two decades, hepatocyte transplantation have been applied in clinical treatment and showed some effect in acute/chronic liver failure and metabolic liver disorders. Here, we sum up the status of clinical hepatocyte transplantation, discuss its value in clinical application and some challenges need to resolve.
