Objective To study the applicability of unilateral and bilateral antegrade cerebral perfusion during deep hy-potbermia circulatory arrest (DHCT) surgery and to determine a better method of brain protection. Methods 60 patients un-derwent aortic arch surgery were random divided into either unilateral cerebral perfusion group with a cannula in the innominate artery (n = 30 ) , or bilateral cerebral peffusion gToup with an additional cannula in the left carotid artery ( n = 30 ). S-100β,neuron specific enolase (NSE) were assayed at the following time points: the beginning of cardiopulmonary bypass (T_1), the beginning of circulatory arrcst( T_2 ), antegradc cerebral perfusion (ACP) 25 min( T_3 ), the end of ACP( T_4 ), the end of car-diopulmonary bypass ( T_5 ) , 1h( T_6 ) , 6h ( T_7 ) and 24h( T_8 ) after operation. Neurological deficit incidence and mortality were also obtained. Results There is no statistical significance for S-100β and NSE plasma concentration among time points of T_1、T_2 and T_3. But every time point among T_4、T_5、T_6、T_7 ,Ts do have statistical significances. The incidence of central nervous system dysfunction in group unilateral ACP was higher than that in group bilateral ACP ( 33.33% vs. 10.00%, P = 0.028 ).But there is no significant difference between the two groups in mortality( 3.33% vs. 6.66% ,P = 1. 000 ). Conclusion There is no significant difference between unilateral ACP and bilateral ACP in 25 min during DHCA. But as the DHCA time extends, the effect of bilateral ACP will be better.

Objective To investigate the effect of Zhali Nusi Recipe ( ZNR) on hemorheological parameters, blood - lipid metabolism, the activities of superoxide dismutase ( SOD) and glutathione peroxidase ( GSH-Px) , and the content of malondialdehyde (MDA) in brain tissues of cerebral ischemia-reperfusion rats with the syndrome of phlegm blended with blood stasis. Methods Ninety rats were randomly divided into sham operation group, model group, nimodiping (10.8 mg/kg) group, high-, middle- and low-dose ZNR groups ( in the dosage of 30, 15, 7.5 g/kg, respectively) , 15 rats in each group. Except the sham operation group, the other groups were given intragastric administration of intralipid for 4 weeks, and then were induced into focal cerebral ischemia-reperfusion by middle cerebral artery occlusion with thread-obstruction method. After post-operation medication for 7 days, the rat general situations, the neurological deficiency symptoms, and the water content in brain tissues were observed. The morphological features of brain tissues were observed after HE staining. The blood was taken from the ab dominal aorta to detect the hemorheological parameters and blood lipid levels. Metabolic levels of free radicals in the brain tissue homogenate were also determined. Results Compared with the sham operation group, neurological deficiency scores of the rats and the water content in the brain tissues of model group were significantly enhanced. The hippocampal neurons of model rats presented typical ischemic changes. In the model group, the hemorheological parameters such as whole blood viscosity, plasma viscosity, hematocrit ( HCT) , and erythrocyte aggregation in dexes ( EAI) were significantly increased, and erythrocyte deformation indexes were significantly decreased; the serum levels of total cholesterol ( TC) , triglyceride ( TG) , low-density lipoprotein cholesterol (LDL-C) were significantly increased, and high-density lipoprotein cholesterol ( HDL-C) level was significantly decreased; the activities of SOD and GSH-Px in brain tissues were significantly decreased, and MDA content was increased significantly ( P<0.05 or P<0.01). Compared with the model group, high-, middle-and low-dose ZNR improved the general situations of the cerebral ischemia-reperfusion rats, increased the neurological deficiency scores, reduced the water content in brain tissues, improved the recovery of morphology of cells in cerebral ischemia tissues, reduced whole blood viscosity, plasma viscosity, HCT and EAI of the model rats, promoted erythrocyte deformation indexes, decreased serum TG, TC, LDL-C levels, increased the activities of SOD and GSH-Px in cerebral ischemic tissues, and sig nificantly decreased MDA content (P<0.05 or P<0.01). And high-dose ZNR had the best effect. Conclusion ZNR has certain protective effect on cerebral ischemia-reperfusion rats with the syndrome of phlegm blended with blood stasis, and the mechanism may be closely related with the improvement ofhemorheology, blood lipid and free radical metabolism in model rats.

Objective To study the methodology and effect of auricle reconstruction with prefabricated expanded fascial flap in temporal and parietal area and skin flap in mastoid area, covered on the Medpor support. Methods Thirty cases of congenital vestigial auricle were involved in this study. The operations were divided into two stages: in the stage I,the temporal and parietal superficial fascia flap was cut with a vascular pedicle in the parietal and temporal superficial area, which was implanted under the skin of mastoid, and then both layers of those were expanded at the same time; in the stage II, this fascial skin flap was cut down and covered on the whole Medpor support to rebuild the man-made auricle. Results Thirty cases were successful after following-up for 6 months to 3 years. Their auricle shapes were vivid; their skin color was normal, and it had no any difference from all around skins, or no any appearance of the support. Conclusions With best understanding the biological characteristics of the Medpor support and choosing the suitable procedures and using the prefabricated expanded support, we could minimize the surgical complications in this operation. The results show that this procedure is satisfactory, without any necrosis of flap, swelling of contour, or appearance of the support. The combination of two flaps is the best method for the auricle reconstruction.

Background: To evaluate the feasibility of treating odontoid fractures in the Chinese population with two cortical screws based on computed tomography (CT) scans and describe a new measurement strategy to guide screw insertion in treating these fractures. Methods: A retrospective review of cervical computed tomographic scans of 128 patients (aged 18–76 years; men, 55 [43.0%]) was performed. The minimum external transverse diameter (METD), minimum external anteroposterior diameter (MEAD), maximum screw length (MSL), and screw projection back angle (SPBA) of the odontoid process were measured on coronal and sagittal CT images. Results: The mean values of METD and MEAD were 10.0 ± 1.1 mm and 12.0 ± 1.0 mm, respectively, in men and 9.2 ± 1.0 mm and 11.0 ± 1.0 mm, respectively, in women. Both measurements were significantly higher in men (p < 0.001). In total, 87 individuals (68%) had METD > 9.0 mm that could accommodate two 3.5-mm cortical screws. The mean MSL value and SPBA range were 34.4 ± 2.9 mm and 13.5°–24.2°, respectively, with no statistically significant difference between men and women. Conclusions The insertion of two 3.5-mm cortical screws was possible for anterior fixation of odontoid fractures in 87 patients (68%) in our study, and there was a statistically significant difference between men and women.
