A canine model of electro-physiologic-electropharmacologic testing on ischemic ventricular tachyarrhythmias were established in the open-chest dogs subjected to programmed electrical stimulation (PES) on 5~8days after acute my-ocardial infarction produced with two -stage occlusion of left anteriol decending coronary artery (LAD) followed by partly reperfusion. The electrophysiologic -electropharmacologic effects of pro-cainamide (PA ) were observed in this canine model. pA distinctly lengthened the QTc interval and the effective refractory period ( ERP) of normal and infarct myocardium in both ventricles and decreasedthe dispersion of ERP in infarct myocardium (IDR) as well as the dispersion of ERP in left ventricle (VDR). The PES - induced ventricular tachycardia (VT) or ventricular fibrillation (VF) was prevented in 5 out of 6 PA treated dogs (n = 6),Normal saline (NS) did not prevented PES- induced VT/VF. The results suggest that PA may be effective in preventing the onset of reentrant ventricular tachyarrhythmias after myocardium ischemic damage.

Objective To explore the practical ways on establishing fine course of oral and maxillofacial surgery effectively. Methods Relying on the advantages of the discipline,great efforts had been made in step-by-step enhancement of the quality of teachers,teaching contents,teaching methods and administration. Results Through the establishing of fine course,we could improve the curriculum system,enhance the force of education team,and improve the quality of education. Conclusion Establishing fine course of oral and maxillofacial surgery depends on the environment of sharing educational resources,adjusting the curriculum system and establishing an excellent educational team.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Its pathogenesis is not only related to abnormal activation of trypsinogen, but also related to calcium overload, mitochondrial dysfunction, impaired autophagy and endoplasmic reticulum stress. However, the mechanism has not been fully elucidated and needs to be further studied. Currently, there is no effective treatment for AP. It is difficult to prevent the loss of pancreatic function. An in-depth understanding of the pathophysiological mechanisms of AP may help to identify the potential therapeutic targets. Therefore, the purpose of this study is to review recent advances in the mechanism of AP in order to provide more research direction for treatment.

OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.
METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.
RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.
CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.
