1.Three-dimensional reconstruction and visualization of the fronto-ethmoidal cells based on CT images.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(20):1573-1576
OBJECTIVE:
Based on contiguous axial computed tomography (CT) images of the frontal sinus, a three-dimensional (3D) visualization and reconstruction of fronto-ethmoidal cells was performed using Intage Realia (version 2011) software to generate a model to accurately understand the anatomical structure of fronto-ethmoidal cells.
METHOD:
Retrospective analyses of nose CT scan data of 50 patients without sinusitis were performed. Using Digital Imaging and Communications in Medicine (DICOM) images of sinus axial CT scans, the 3D visualization and reconstruction of the sinus was performed using the Achilles tendon and nasal passage modes in Intage Realia (version 2011) software on personal computers. Two segmentations were performed on the reconstructed sinus, and the structures of the agger nasi, frontal cells, and supraorbital cells and the relative locations of the frontal sinus drainage pathway and cells were observed.
RESULT:
The 3D visualization of the fronto-ethmoidal cells and frontal sinus drainage pathway was successful, allowing accurate observation of the anatomical characteristics of the fronto-ethmoidal cells.
CONCLUSION
The 3D visualization of fronto-ethmoidal cells can be reconstructed based on contiguous axial CT images of the sinus, allowing an accurate understanding of the anatomical structure of fronto-ethmoidal cells and is well prepared for frontal sinus surgeries.

Objective To explore the relationship between single nucleotide polymorphisms (rs12953-717) of SMAD7 and susceptibility of non-small cell lung cancer (NSCLC) in Chinese Han population.Methods A single nucleotide polymorphisms (rs12953717) from SMAD7 was detected via Sequenom system in 528 NSCLC cases and 762 healthy controls.Data was statistically analyzed by unconditional Logistic regression method.Results rs12953717 had significant differences between non-small cell lung cancer patients and the controls.Compared with CC/TT (CC combined with TT) genotype,the adjusted odds ratio for the CT genotype was 4.107 (95% CI:3.206 ~ 5.260,P =0.000 1).Smokers had a 2.004 odds ratio (95 % CI =1.583 ~ 2.537,P =0.000 1) of NSCLC compared with the controls.There was a 10.074-fold increased risk of NSCLC among the subjects with CT genotype and smokers.Conclusion The polymorphism of rs12953717 may have relation with risk of NSCLC.Heterozygote (CT) is a susceptibility genotype of NSCLC.Smoking is one of the risk factors of NSCLC.Smoking and CT genotype have synergistic effects on NSCLC susceptibility.

Objective To evaluate the technique of Kirschner with a hole and tensile developed from the Kirschner tensile band wire.Methods Forty-two cases with fracture of patella and 23 cases with fracture of ulna olecranon were successfully operated with this apparatus.Average age was 42 years old(range,24~78 years),including 38 male patients and 27 females totally.Results Fracture healing rate was 100%,the rate of excellent and good result was 95% after 9 months to 3 years follow-up.No tenderness,skin penetrating caused by the bolt ends,and loosen fixations were found.Conclusion This apparatus can be considered as a rigid,safe and effective method and can meet the biomechanics principle of the Kirschner tensile band wire,complication of the Kirschner tensile band wire could be avoided by using this technique.

Objective: To investigate alteration and cross link of the aortic intima and platelet endogenous L-Arg/NOS/NO pathway induced by water immersion restraint (WIR) stress. Methods: After 7 h of WIR stress, the aortic intima was isolated and prepared the platelet, then NO_2- production released from aortic intima and platelet was measured with Greiss regent, NOS activity and L-arginine transport activity were detected by isotope tracer method. Results: After 7 h of WIR stress, the levels of NO_2- from platelet and aortic intima obviously decreased by 57% and 46% respectively as comparied with the control rats (P

Objective Pulmonary artery atresia (PAA) with intact ventricular septum (IVS) is an anatomically heterogeneous entity. A variety of surgical strategies is possible. We sought to evaluate the clinical results of various surgical corrections of PAA with IVS. Methods A retrospective review of our surgical database revealed 17 patients with PAA and IVS operation between January 1992 to August 2004. There were 9 males and 8 females. The age ranged from 15 days to 12 years [(25.5?7.9) months]. The body weight was 3.5 to 28.0 kg [(7.8?5.4) kg]. Radical operation was performed in 10 cases with the Z score -2.3~1.2 (-0.78?0.34), the pulmonary artery index (PAI) 149.53~297.89 mm~2/m~2 (206.35?82.15 mm~2/m~2). Two infants received BT shunt operation for the severe hypoxia at first postoperative day. Palliative operation was performed in 6 cases with the Z score -6.1~0.2 (-2.7?0.92), the PAI 39.88~218.29 mm~2/m~2 (131.85?72.93 mm~2/m~2), including bi-directional Glenn bypass (2 cases), systemic-to-pulmonary arterial (BT) shunt (1 case), right ventricular outflow tract (RVOT) reconstruction and BT shunt (3 cases). One patient accepted one and a half ventricular repair, first underwent bi-directional Glenn bypass operation, two years later ,underwent ASD occulsion、PDA occlusion and RVOT reconstruction. Results 3 patients(16.7%) died at perioperative time [two patients who had the radical operation, but next day, had the BT shunt operation, one patient had the right ventricular outflow tract (RVOT) reconstruction and BT shunt]. The rest recovered smoothly. The main complications included low cardiac output in 3 patients, hypoxemia in 3 patients, hydrothorax in 1 patients and right heart failure in 3 patients. Conclusion Surgical outcome for patients with the PAA with IVS maybe satisfactory, strategries are to be chosen according to the anatomic subtypes such as the tricuspid valve diameter, right ventricular size, pulmonary artery index and coronary anatomy.

To ensure the quality of direct digital radiography images, the management and control of image quality, basic adjustment of facilities post-processing, and raising technicians' professional quality mut be performed. To protect patients from radiation should be emphasized in medical staffs. Radiation should be reduced when ensuring the images' quality, and green examination concepts should be advised.

Objective To investigate the serum level of vascular endothelial growth factor (VEGF) in patients with coronary artery disease (CAD) and its clinical significance. Methods The study included 36 patients with CAD and 10 non-coronary heart disease patients as the control. The concentrations of serum VEGF in the coronary veins and the aorta were measured by an enzyme-linked immunsorbent assay (ELISA). Total mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation, and were cultured in M199 medium supplemented with 20% fetal bovine serum. After 7 days culture, attached cells were collected. The effect of VEGF on the migration of endothelial progenitor cells (EPCs) were assayed with modified Boyden chamber assay. Results The serum VEGF levels of stable angina pectoris (SAP) patients (208.46?44.74 ?g/L) and acute coronary syndrome (ACS) patients (267.29?93.99 ?g/L) were much higher than that of the controls group (120.77?26.25 ?g/L,P
