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 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.

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.

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.

Objective To investigate the influence of continuous veno-venous hemofiltration (CVVH) on cardiac output (CO) value and parameters of hemodynamics monitored by transpulmonary thermodilution technique in critical patients. Methods A prospective cohort study was conduced. Sixty-two critical patients admitted to intensive care unit (ICU) of Zunyi Medical College Affiliated Hospital from January 2011 to October 2015 were enrolled. All of the patients received CVVH through femoral vein puncture catheter. The CO value was monitored before CVVH operation, immediately after CVVH operation (8 ℃ normal saline was injected immediately after the output of blood from the arterial end), 5 minutes after operation, the time at the sudden interruption (press pause key after 10 minutes of operation) and resumed immediately, 15 minutes and 30 minutes after operation by pulse-indicated continuous cardiac output (PiCCO) with transpulmonary thermodilution method. The changes in heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and blood temperature were observed at all time points. Results From CVVH before start to 5 minutes thereafter, CO values were not significantly changed in patients, fluctuating in 6.96 (7.33, 8.67)-6.98 (6.43, 7.45) L/min. When CVVH was suddenly interrupted, CO value was immediately increased to the peak 8.04 (7.36, 8.77) L/min, which showed statistically significant difference as compared with other time points (all P < 0.01). Immediately after the CVVH recovery from interruption, the CO value dropped to 4.71 (4.14, 7.26) L/min, and it was significantly lower than those at other time points (all P < 0.01). With the CVVH recovery, the patients' CO value was gradually restored to the stable operation ahead of interruption [4.71 (4.14, 7.26)-6.85 (6.08, 7.26) L/min]. During CO monitoring, HR, MAP, CVP and blood temperature of the patients were at the same level, and no significant changes were founded. Conclusions CVVH interruption of immediate PiCCO monitoring CO value were significantly increased, immediately after the CVVH recovery the CO value were significantly reduced, and the normal operation of CVVH did not affect the CO value monitoring. Hemodynamics and blood temperature of all patients were stable during CVVH.
