AIM: To retrospectively analyze the effect of different surgical treatment on intraocular foreign bodies, according to different types and position.
METHODS: Clinical data of 46 cases diagnosed with intraocular foreign bodies from June 2010 to April 2013 were retrospectively analyzed.
RESULTS:Intraocular foreign bodies in anterior segment could be removed or magnetically attracted directly, intraocular foreign bodies in posterior segment could be attracted if there was accurate location. Vitrectomis was more favorable for the non magnetic or intraocular foreign bodies in posterior segment. In 46 cases, all intraocular foreign bodies ( 100%) in posterior segment were removed successfully. Among them the functional cure in 33 cases ( 72%) , the anatomical cure in 12 cases ( 26%) , discharged in 1 case (2%).
CONCLUSION:The aim of operation is to reconstruct of eyeball structure preserve and restore visual function. We should find more appropriate mode of operation and timing of surgery according to the foreign bodies'different types and injury of eyeball, reduce complications, preservation eyeball and improve visual function.

Objective: To investigate the effects of aspisol on expressions of cyclooxygenese-2 (COX-2), matrix metalloproteinaseses-9 (MMP-9) proteins in human breast cancer MDA-MB-231 cells. Methods: MDA-MB-231 cells were incubated with aspisol at various concentrations for 24 h. The morphological changes of MDA-MB-231 cells were evaluated by HE staining. The inhibitory effects of aspisol on the proliferation of MDA-MB-231 cells were determined by MTT assay. The effects of aspisol on the expressions of COX-2 and MMP-9 in MDA-MB-231 cells were measured by Western blotting. Results: Under light microscope the cells in aspisol treatment groups showed decreased density, round shape, and light staining of nucleus. Aspisol significantly inhibited the proliferation of MDA-MB-231 cells (P < 0.01). Compared with the control group, aspisol dose-dependently inhibited the expressions of COX-2 and MMP-9 protein in MDA-MB-231 cells (P < 0.05). Conclusion: This study suggested that aspisol inhibited the expressions of COX-2 and MMP-9 protein in breast cancer MDA-MB-231 cells.

Objective To establish the pharmacodynamic model of sevoflurane with bispectral index (BIS) as the effective index in pediatric patients.Methods Thirteen ASA physical status Ⅰ or Ⅱ pediatric patients,aged 4-9 yr,weighing 12-39 kg,undergoing non-cardiac surgery,were selected in the study.The pediatric patients sequentially inhaled 1％,5 ％ and 1％ sevoflurane via a face mask and each concentration was inhaled for 15 min.BIS value,HR,BP and SpO2 were automatically recorded every 10 s.Based on nonlinear mixed effect modeling,the population pharmacodynamic model of sevoflurane was established using NONMEM software.The effect of age on the pharmacodynamic parameters was evaluated using a stepwise forward addition then backward elimination modeling approach.The standard for model improvement was defined as a decrease in the value of the objective function by more than 3.84.Results Twelve pediatric patients,aged 4.0-8.5 yr,weighing 12.8-38.0 kg,with body height of 92-135 cm,were enrolled in this study and the data which were enrolled comprised 2964 effective concentration-time-BIS points.The model was not improved significantly with any covariates (age,body height,and body weight) introduced (P ＞ 0.05).The estimated parameters of the final pharmacodynamic model of sevoflurane were as follows:ke0 =O.516/min ; EC50 (BIS50) =2.11％ ; γ =2.46 ; E0 =74.6 ; EMAx =11.2.Conclusion The pharmacodynamic model of sevoflurane is successfully established with BIS as the effective index in pediatric patients,and the analysis for each parameter of the model indicates that the sensitivity to sevoflurane is lower,but the blood-brain equilibration time of the drug is shorter and the onset and recovery are faster in children than in adults.

AIM: To study the effects of resveratrol on the proliferation of human retinal vascular endothelial cells induced by cobalt chloride-simulated hypoxia in vitro.METHODS: CoCl2 (100μmol/L) was used to simulate hypoxic condition, and human retinal vascular endothelial cells were cultured in vitro as model. The cell proliferation was determined by MTT method; SABC method was employed to test the expression of vascular endothelial growth factor (VEGF); and computer image analyzer was used to process data. The effects of resveratrol on the proliferation of vascular endothelial cells were observed.RESULTS: Resveratrol inhibited the proliferation of human retinal vascular endothelial cells induced by CoCl2 in a dose- and time-dependent manner in vitro, meanwhile VEGF expression in all groups which were administered medicine was down-regulated. Both kinds of inhibitive effects of resveratrol were statistically significant (P<0.01).CONCLUSION: Resveratrol can significantly inhibit the proliferation of human retinal vascular endothelial cells and the expression of VEGF, which may provide a new approach for prevention and treatment of retinal neovascular diseases.

Objective To study and estimate the effective dose of interventional employees in the common cerebralvascular, cardiovascular and liver interventional diagnosis and treatment.Methods The absorbed doses of tissue or organ of anthropomorphic phantom in these three procedures were estimated by the anthropomorphic phantom experiment.The effective doses were calculated by the tissue weight factor which was given by International Commission on Radiological Protection publication 103.Results The effective doses to high, medium and low group were 24.0, 9.7,6.8 μSv for cerebralvascular interventional diagnosis and treatment, and 36.3, 29.3, 17.8 μSv for cardiovascular interventional diagnosis and treatment, and 23.9, 11.3, 5.5 μ Sv for liver interventional diagnosis and treatment, respectively.Conclusions The effective doses of high, medium and low group of interventional employees in cardiovascular interventional procedure are higher than those of cerebralvascular and liver interventional procedures.

Objective To evaluate the implication of LEEP cervical conization on the outcome of subse-quent pregnancy. Methods The study group comprised 85 women who had a LEEP in Renmin Hoapital of Wuhan University during Jan. 2005 and Jan. 2007 ,and then had a subaequent pregnancy. 109 control women were extracted from outpatient clinic who received antenatal care in the same period with no history of cervical surgery, matching by age, health condition and perinatal stage. The pregnancy outcome of two groups were analyzed. Results Women who had a LEEP were more likely to give preterm delivery than controla (9.88% va 3.70%). But there waa no differ-ence in preterm delivery(χ2=2.97, P>0.05). So were low birth weight infants, preterm premature rupture of mem-branes (pPROM) or cesarean section. On a further study, we found that the time interval between cervical conization and subsequent pregnancy was associated with risk of preterm birth. The shorter time interval, especially shorter than 6 months,the higher risk of preterm birth. Conclusions LEEP cervical conization is not associated with an in-creased risk of preterm delivery, low birth weight infants, pPROM or cesarean section. LEEP conization is a more sol-id choice for women who want to preserve reproductive function. But it would be better for them to have pregnancy plan six months later.

OBJECTIVE:To investigate the utilization of antineoplastic drugs in our hospital. METHODS:A retrospective analysis was conducted on antineoplastics used during 2005-2007 in our hospital in respect of the consumption sum,DDDs and average daily cost etc. RESULTS:Over the 3 years,the proportion of antineoplastics showed a year-on-year increase in consumption sum,with the antitumor plant amedica topping the consumption sum list and Tamoxifen topping the DDDs list for three years. Domestic drugs,injections and drugs on the RDL (reimbursable drugs list for basic medical insurance) showed high DDDs in our hospital. CONCLUSION:The consumption of antineoplastics is basically rational in our hospital,yet its management remains to be further tightened.
