950 mL/L for 2 hours.Gross anatomical changes and histological changes(HE staining)of lungs were observed,VEGF expression was detected by immunohistochemical method.Results Two rats in hypothermia-hypoxia group and 4 rats in rewarming-reoxygenating group died while none in control group.Lungs of hypothermia-hypoxia group and rewarming-reoxygenating group represented edema and punctiform,local and diffuse pulmonary hemorrahge.Histopathological changes included pulmonary edema,alveolar septum broken,pulmonary alveoli fusion and pulmonary hemorrahge.More severe pathological change could be found in rewarming-reoxygenating group.Optical density value of VEGF expression in 3 groups were 0.29?0.06,0.36?0.05,0.22?0.05,respectively,there were significant diffe-rences of VEGF expression between 3 groups(F=15.64 P

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

Objective To evaluate the usefulness of real-time three-dimensional transesophageal echocardiography (RT-3D TEE) in the perventricular device occlusion of the ventricular septal defect (VSD).Methods Sixty patients underwent perventricular device occlusion of VSD were divided into two groups.Group A:30 patients,3D images of VSD were obtained intraoperatively by RT-3D TEE.3D images were analyzed and the maximal and minimum area and maximal diameter of VSD were measured in the cardiac cycle.The size of selected VSD occluder was the diameter calculated from the maximal area based on the formula πD2/4 and plus 1～2 mm.Simultaneously,two dimensional transesophageal echocardiography (2D TEE) images of VSD were obtained and measured on standard views.Group B:other 30 patients,intraoperative 2D TEE was performed to measure the diameter of VSD on standard views.The selection VSD occluder was based on the maximal diameter plus 1～2 mm.Results The VSDs shape showed oval,class round and irregular by RT-3D TEE imaging.There was a significant difference between the maximal area and smallest area of VSD appeared in the cardiac cycle obtained by RT-3D TEE (P<0.01).There was a significant difference between the maximal diameter by measurement of RT-3D TEE and 2D TEE (P<0.01).Of all 30 patients with evaluation of VSD size based on the RT-3D TEE,1.1 times attempts of device occlusion were performed on one patient (33/30).Of the other 30 cases with evaluation of VSD size by 2D TEE,2 cases were failed with device occlusion because of instant residual shunt.Of the remaining 28 cases,1.43 attempts of device occlusion were performed on one patient (40/28).Conclusions RT-3D TEE can accurately reveal the size of VSD,and aid in the selection of VSD occluder in the device occluding procedure of VSD.

Objective To investigate the diagnosis and treatment of pancreatic cystic tumors. Methods The clinical data of 35 patients with pancreatic cystic tumors were retrospectively analyzed. Results The preoperative diagnosis rate was as follows: ultrasound was 28.6% ( 10/35 ), CT 44.4% ( 12/27 ), MRI 70% (7/10). Twenty-eight cases underwent operation and were diagnosed finally by postoperative pathology. Serous cystic neoplasm (SCN) was found in 2 cases, mucinous cystic neoplasm (MCN) in 9 cases,cystic adenocarcinoma in 7 cases, intraductal papillary mucinous neoplasm ( IPMN ) in 3 cases, solid pseudopapillary tumor (SPT) in 7 cases. Twenty-three cases were followed up successfully. The post-operative 5 years survival rate was 62.5% (5/8) in pancreatic cystic adenoma without recurrence. The longest survival time in cystic adenocarcinoma after complete resection was 5 years and 8 months, while in which after incomplete resection was 6 months. The 4 cases of SPT are all alive, and one of them has survived for 4 years as the longest one. Conclusions It is difficult to diagnose the pancreatic cystic neoplasm accurately before operation. CT and MRI may be helpful to make the diagnosis. Surgical resection is the most effective treatment. The enhancement of the communication and cooperation between the related departments, the early diagnosis, and the appropriate operation are needed to improve the diagnostic and therapeutic efficacy.

Objective To investigate the changes of cortical thickness and surface area in patients with bipolar depression(BD),and to explore the relationship between abnormal changes in gray matter and clinical symptoms.Methods 28 BD patients and 28 healthy controls underwent T1-weighted MRI.The Freesurfer software was used to process the T1 images,which used a set of automated sequences to analyze cortical thickness and surface area on 66 regions (33 regions of each hemisphere),and the correlation with clinical features was also calculated.Results Compared with controls,BD patients showed thinner cortical thickness in left medial orbitofrontal cortex((2.40±0.12) mm vs (2.55 ±0.18) mm,P=1.2× 10-3) and left rostral anterior cingulate((2.66±0.21) mm vs (2.88±0.27) mm,P=3.1 × 10-4),and smaller area of left cuneus((1 443.13± 131.00) mm2vs (6 634.70±600.16) mm2,P=2.7× 10-4) and right superior frontal gyrus ((6 634.70±600.16) mm2vs (7 300.50±653.39) mm2,P=1.3× 10-3).In addition,the negatively correlation was found between the cortical area of left cuneus and effective illness duration (r=-0.471,P=0.018),and the cortical thickness in left rostral anterior cingulate and total score of HAMD-17(17-item Hamilton Rating Scale for Depression) (r=-0.508,P=0.009).Conclusion There are abnormal altertion of cortical thickness and cortical areas of emotional circuit in bipolar depression,but the brain areas are not completely overlapping.Correlation analysis suggests that cortical thickness and area is related to different clinical features.

ObjectiveTo evaluate the therapeutic value of neoadjuvant chemotherapy for patients with stages Ⅱ and ⅢA(Only T3N1M0) breast cancer,and assess the relationship of the tumor size and pathologically complete response.MethodA total of 408 breast cancers patients at stages Ⅱ and ⅢA,were studied,which were divided into neoadjuvant chemotherapy group (group A) and control group (group B).All patients of group A received 2-4 cycles NAC with TE scheme in breast cancer.The impact of neoadjuvant chemotherapy on surgical methods choice,local control rate,5-year overall survival rate and 5-year disease free survival rate were analyzed.ResultsFor patients of stage Ⅱ,the rate of breast conservation significantly increased from 23.6％ to 49.1％ (P =0.000) and there was no significant difference between groups A and B ( P =0.939,0.858 ) in 5-year overall survival rate and disease free survival rate.For patients of stage ⅢA,the 5-year overall survival rate (59.8％ ) and disease free survival rate (51.8％) in group A were greatly higher than that in group B (35.7％ and 27.6％ ) (P =0.000,0.000).The 3-year local relapse and metastasis rate(7.9％ ) was lower than group B (18.4％)(P ＜ 0.05 ).The tumor less than 3.0 cm is easy to achieve pathological complete remission (P =0.001 ).ConclusionsThe neoadjuvant chemotherapy can improve potential rate of breast conservation,reduce the rate of local-regional recurrence rate for the patients with stage Ⅱ and ⅢA breast cancer,and also improve the 5-year survival rate for the patients of stage ⅢA.Patients with clinically complete response or PCR may have higher 5- year overall survival rate and disease free survival rate.Primary tumor size was found to be the significant predictive factor for pathologically complete response to neoadjuvant chemotherapy in patients with breast cancer,particularly,the small tumor is easy to reach pathologically complete response.
