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 evaluate the effect of isoflurane on the expression of phosphorylated glycogen synthase kinase-3 beta (p-GSK-3β) and β-catenin in neural stem cells (NSCs) in the hippocampus of developing rats.Methods Twenty-four 7-day-old Sprague-Dawley rats,weighing 15-20 g,were divided into 2 groups (n =12 each) using a random number table:control group (group C) and 2％ isoflurane group (group Ⅰ).Group C inhaled 30％ oxygen for 4 h.Group Ⅰ inhaled 2％ isoflurane in 30％ oxygen for 4 h.Six rats were randomly selected from each group,and 5-bromodeoxyuridine (BrdU) 200 mg/kg was intraperitoneally injected immediately before anesthesia to assess the proliferation of NSCs in the hippocampal dentate gyrus.The rats were sacrificed at 6 h after the end of anesthesia,and hippocampi were isolated for determination of the number of BrdU positive cells in the dentate gyrus (by immunohistochemistry) and expression of p-GSK-3β and β-catenin in hippocampal tissues (by Western blot analysis).Results Compared with group C,the number of BrdU positive cells was significantly decreased,and the expression of p-GSK-3β and β-catenin was down-regulated in group Ⅰ (P＜0.05).Conclusion Isoflurane can inhibit the proliferation of NSCs in the hippocampal dentate gyrus of developing rats,and the mechanism may be related to down-regulation of the expression of p-GSK-3β and β-catenin.

Objective: To assess the accuracy of multi-slice spiral CT (MSCT) with imaging reconstruction in judging bronchial involvement from central lung cancer. Methods: MSCT was done in 30 patients who were diagnosed as central lung cancer. Images of bronchi related to lobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the relation between tumor and bronchus was assessed prospectively with both axial CT and CT with imaging reconstruction in comparison with subsequent pathologic and surgical findings. Results: All 30 patients underwent thoracotomy, lobectomy or pneumonectomy. Total 66 bronchi were studied. Compared with axial CT images, CT with imaging reconstruction was better in judging the relation of bronchus and tumor in comparison with subsequent pathologic and surgical findings (0.01

Objective: To assess the peculiarity in fluorine-18 fluorodeoxyglucose (FDG) uptake in patients with bronchial alveolar carcinoma. Methods: From December, 1998 to April, 2002, 22 patients with bronchial alveolar carcinoma (BAC) were imaged with FDG-PET (positron emission tomography) before surgery. Their maximum and mean standard uptake value (SUVmax and SUVmean ) of tumor and SUV of normal lung (SUVlung) were measured. Results: All tumors were detected by FDG-PET. FDG uptake of tumor was higher than that of normal lung (P

Objective To evaluate the effects of dexmedetomidine on the hemodynamics and the heart rate variability(HRV)in patients under-going lower limbs operations with application of tourniquet. Methods Forty patients undergoing lower limbs operations with application of tourni-quet were randomized assigned to dexmedetomidine group(group D,n=20)or control group(group C,n=20). After combined spinal-epidural anesthesia,group D received a continuous infusion of dexmedetomidine(0.5μg/kg for 10 min for loading dose and followed by 0.2μg·kg-1·h-1) until tourniquet deflation. The control group received normal saline instead. Mean arterial pressure(MAP),heart rate(HR),saturation of pulse ox-imetry(SpO2),low frequency power(LF),high frequency power(HF)and LF to HF ratio(LF/HF)were recorded at regular time points:imme-diately before loading dose(T0),before tourniquet inflation(T1),15 min after tourniquet inflation(T2),30 min after tourniquet inflation(T3),45 min after tourniquet inflation(T4),60 min after tourniquet inflation(T5),1 min after tourniquet deflation(T6),5 min after tourniquet deflation (T7)and 10 min after tourniquet deflation(T8). Results Compared with T0,the MAP of group D significantly decreased at T6-T8(P<0.05). Compared with T0 and T1,the MAP of group C increased at T2-T5(P>0.05). Compared with T2-T5,the MAP of group C significantly decreased at T6(P<0.05). Compared with group C,the MAP of group D significantly decreased at T6 and T7(P<0.05). Compared with T0,the HR of group D significantly decreased at T1-T8(P<0.05). Compared with T0,the HR of group C had no significant change at T1-T5(P<0.05). Compared with T1-T5,the HR of group D and group C significantly increased at T6(P<0.05). Compared with group C,the HR of group D significantly decreased at T1-T4 and T6(P<0.05). Compared with T0,the SpO2 of group D and group C significantly decreased at T6(P<0.05). Compared with group C,the SpO2 of group D significantly decreased at T1-T3(P<0.05). Compared with T6,LF of group D and group C significantly increased at T7(P<0.05). LF were comparable between groups D and C(P>0.05). Compared with T0,the HF of group D significantly increased and the LF/HF of group D significantly decreased at T1-T4(P<0.05). Compared with group C,the HF of group D significantly increased and the LF/HF of group D significantly decreased at T1-T4(P<0.05). Conclusion The appropriate dose of dexmedetomidine(loading dose 0.5μg/kg and maintenance dose 0.2μg · kg-1 · h-1)can significantly increase vagal tone and improve cardiac sympathetic and parasympathetic balance during tourniquet appli-cation.

Objective To establish an improved hemisection model of spinal cord injury(SCI)in rats with less severe injury and increased sur-vival rate. Methods Female Sprague-Dawley rats(n=20)were randomly divided into 2 groups:standard and improved hemisection model of SCI. Basso-Beattie-Bresnahan(BBB)scores were carried out to determine the hindlimb locomotor function at 1 d,3 d,1 week and 2 weeks post SCI,respectively. In addition,duration of operation,blood loss,location of posterior midline,and success rate of spinal cord exposure during the second surgery were used as the main parameters to evaluate the significance of the new model. Results Compared with the standard hemisection model,the improved hemisection model of SCI exhibited shorter duration of operation,less blood loss,higher BBB score,more accurate location of posterior midline,and higher success rate of spinal cord exposure during the second surgery. Based on the improved hemisection model of SCI, transplantation model of scar tissue in spine cord was then successfully constructed with a success rate above 70%. Conclusion The improved hemisection model of SCI shows significant advantages in many aspects related to the operation,which is applicable to the study of SCI,especially the non-acute SCI.
