AIM: To investigate the effect of testosterone with varied concentrations on the fibr inolysis activity of HUVEC and its mechanism. METHODS: Human umbilical vein endothelial cells (HUVEC) were cul tured as recommended. After confluence, the cultures were treated with testoster one(3 ?10 -10, 3?10 -9, 3?10 -8,3?10 -6, 3?10 -5 m ol/L) , and the control confluent cells were cultured in the same medium witho ut steroid. MTT experiment was repeated for 72 hours to investigate each groups' cell proliferation. The tPA and PAI-1 antigen levels were assayed with ELISA K its. Then with HUVEC incubated in androgen receptor antagonist (flutamide) 3 hou rs previously, the experiment was repeated. RESULTS: Testosterone at physiologic or lower concentrations (3 ?10 -10 to 3?10 -8 mol/L ) stimulated the secretion of tPA by HUVEC (P

ObjectiveTo compare the surgical outcomes of total abdominal hysterectomy (TAH) and total vaginal hysterectomy (TVH).MethodsThe clinical data of 509 TAH cases and 799 TVH cases including operating time, bleeding volume, days being in hospital and outcome of 3 months following-up were analyzed retrospectively.ResultsThe average operating time and bleeding volume of TVH were 47.6 minutes and 199 ml respectively, less than that of TAH (128 minutes and 241 ml). The days being in hospital of TVH were also less that of TAH, and 12-Short Form Health Survey (SF-12) scores of TVH were higher than that of TAH.ConclusionTVH has minor lesion and is helpful for improving the quality of patients' life.

ObjectiveTo evaluate the clinical effectiveness of oral sensorimotor therapy on oral motor dysfunction after cerebal palsy (CP).MethodsThirty-two CP children were confirmed the type of cerebral palsy by neurological examination and developmental age by Gesell's developmental scale. Oral sensorimotor therapy was performed one time a day by speech-language therapist.Before and after a treatment period of 3 months,the oral motor and language-speech ability of each case was assessed using Oral Motor Scale and Sign-Significate relations.ResultsAfter treatment, the oral motor function had been improved significantly(t=11.946,P<0.01) and the oral motor score was meanly increased by 14.94 score.The levels of oral language comprehension and expression had also been improved significantly(t=5.376,P<0.01;t=7.552,P<0.01).Articulation of 28 cases(87.5%) was improved. ConclusionOral sensorimotor therapy is effective on improving oral motor function, articulation,as well as on increasing language comprehension and expression.

AIM: To investigate the role of retinal pigment epithelium (RPE) in the growth of Müller cells using a co-culture system in vitro . METHODS: Müller cells were cocultured with RPE cells under both normoxic and hypoxic conditions in Transwell chamber culture system. Müller cell proliferation was evaluated by MTT assay. The number of cells which migrate through micropores and stay on the outer bottom side of insert systems were observed and counted. RESULTS: The activities of proliferation and migration of Müller cells when cocultured with RPE cells were significantly higher than those of the Müller cells when cultured alone at all time points under both normoxic and hypoxic conditions. However, for both the coculture and control groups, there is no significant difference between the measurements at 3 and 6 hours. CONCLUSION: Evidence suggests that RPE, when co-cultured with Müller cells, can stimulate migration and proliferation of Müller cells under both hypoxic and normoxic conditions in a time-dependent manner; how-ever, there is no evidence to support the synergetic interaction of RPE and Müller cells co-cultured under hypoxic conditions.

Background More and more evidences suggest that the interaction of retinal progression of retinal diseases.Objective Present study was to investigate the primarily cultured and digested using explant culture method and trypsas acidic protein(GFAP) staining,S-100 staining and cytokine-18 staining co-cultured under the normoxia and hypoxia using transwell chamber,and the proliferation and migration of cultured RPE cells were examined using MTT and compared with only RPE cells cultured group at 3, 6, 24 and 48 hours.Results Over 90% of primarily cultured RPE cells showed the positive response for S-100.The proliferation and migration of RPE cells were significantly increased in hypoxia condition compared with normoxia condition (P＜0.01).In hypoxia group,amount of proliferation and migration of RPE cells in co-culture group were higher than the only RPE cells cultured group(P＜0.01).Conclusion Hypoxia appear to aggravate the proliferation and migration of RPE cells under the hypoxia status.
