Objective To explore the significance of mediastinum drainage tube in prevention and treatment of intrathoracic anastomotic leak after esophagectomy. Methods The morbidity and prognosis of intrathoracic anas-tomotic leak after esophagectomy in 180 patients with esophageal or cardia carcinoma (group A) who used mediasti-num drainage tube in operation from 2006 to 2008 was studied retrospectively,and were compare with 154 patients (group B) without mediastinum drainage tube from 2004 to 2006. Results The morbidity of intrathoracic anasto-motic leak after esophagectomy was 1.67% (3/180) in group A,and 4.55% (7/154) in group B,but no difference between them(χ2=1.4807, P>0.05) were found. Compared to group B, the final diagnosis of anastomotic leak in group A was early [(6.7±0.6) vs (10.0±2.1) days after operation (t=2.62, P<0.05)] and the duration of fe-ver was short [(5.3±1.5)vs (43.0±20.9) hours (t=4.39, P<0.01)]. The prognosis of 3 cases in group A was well, who all recovered without operation and had shorten hospital days than group B [(23.7±5.9)d vs (45.3± 5.0)d,t=4.86,P<0.01)]. In 7 cases of group B,there were 5 cases underwent second operation,but only 3 cases recovered, the case fatality rate was 2.60% (4/154), higher than in group A (0, Fisher, P<0.05). Conclusions Although the mediastinum drainage tube used or not used in esophagectomy is unrelated with the occurrence of anas-tomotic leak, and the significance to use it is that it can help to discover anastomotic leak early, and control mediasti-num infection effectively without reoperation,and improve patients' prognosis.

Objective To evaluate and analyze the diagnostic accuracy of 256-slice computed topographic angiog-raphy (CTA) and coronary angiography (CAG) in patients with coronary artery disease (CAD). Methods One hundred and one patients (suspected CAD and confirmed CAD with re-examination) underwent the 256-slice CTA and CAG were includ-ed in this study. The coronary artery imaging data of 101 patients were retrospectively collected and analyzed. Calculations for accuracy were conducted on a segmental basis. A total of 1 313 comparable segments were evaluated. The accuracy of 256-slice CTA was evaluated in the diagnosis of moderate and severe stenosis of coronary artery(stenosis in segments of cor-onary artery≥50%). The values for diagnostic accuracy of 256-slice CTA were analyzed, including mild stenosis: ＜50%, moderate stenosis:50%~75%, severe stenosis:76%~100%and complete occlusion. Results The sensitivity of 256-slice CTA for diagnostic accuracy to coronary heart disease was 94.87%, and the specificity was 52.17%. The positive predictive value was 87.06%and the negative predictive value was 75.00%. The accuracy rates of 256-slice CTA for evaluating the cor-onary artery stenosis were:mild stenosis (44.23%), moderate stenosis (44.23%), severe stenosis (40.00%) and total occlusion of coronary artery (51.77%), respectively. Conclusion The diagnostic value of 256-slice CTA for the degree of coronary ar-tery stenosis is insufficient, which can be used as a potential alternative screening examination to detect coronary artery ste-nosis in suspected patients and a method of re-examination in low risk patients with CAD.

Objective To compare the proteome difference between multiple myeloma cell line U266 cells treated and untreated with PS-341, to investigate the potential drug targets, and to provide theoretical evidence for clinical therapy of multiple myeloma. Methods Two-dimensional gel electrophoresis (2-DE) was performed to separate proteins from treated and untreated U266 cells with proteasome inhibitor PS-341. ImageMaster 2D Platinum software was used to analyze 2-DE image, and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify the differentially expressed proteins. The expression levels of differential protein BAG-2 in the 2 groups of U266 cells lines were detected by Western blot. Results The 2-DE reference pattern of treated and untreated U266 cells with PS-341 was established. A total of 31 differential proteins were identified by MALDI-TOF-MS, 27 of which were down-regulated after PS-341 treatment. The differential expression level of BAG-2 in the 2 groups of U266 cells was confirmed by Western blot. Conclusion Some down-regulated proteins may be the potential drug targets of proteasome inhibitor PS-341.

ObjectiveTo study the morphology, normal values and lateral asymmetry of Chinese calcarine sulcus on MRI. Methods High-resolution and transverse MRI were obtained from 40 female volunteers. Brainvisa software was used to reconstruct the calcarine sulcus and measure its average length, depth and width automatically. Results The posterior branch of calcarine sulcus showed six types in the median sagittal plane: bifurcation(32.50%), single peak(25.00%), flat (16.25%), S-shaped (15.00%), double peak(7.50%) and other shape (3.75%); its location had three types: inferior(72.50%), middle(21.25%)and superior(6.25%). The depth of left calcarine sulcus was (15.24±2.67)mm, and the right one was (16.97±3.25)mm, which revealed great statistical significance (P＜0.000 1). The width of left calcarine sulcus was (3.14±0.91)mm, and it was (3.19± 0.83)mm in the right side. The bottom length of calcarine sulcus: the left was (86.47±16.85)mm, the right was (83.62±17.10)mm. The top length of calcarine sulcus: the left was (70.52±12.40)mm, the right was (64.90±15.17)mm. There were not statistical significance in width, bottom length and top length between left and right calcarine sulci. More than half of the end part of calcarine sulci turned to the lateral surface of cerebral hemisphere.Totally 63 cases (78.75%) were found with prominent calcar avis. Conclusion Significant difference of depth between left and right calcarine sulcus of female was found. Three-dimensional reconstruction is an effective method to study the anatomy of calcarine sulcus.
