Objective: To evaluate the safety and feasibility of hybrid thoracoscopic surgery and catheter ablation in treating the patients of long-standing persistent atrial fibrillation (AF) with preliminary experience. Methods: A total of 15 consecutive relevant patients treated in our hospital by hybrid thoracoscopic surgery and catheter ablation from 2014-04 to 2016-03 were studied. The average AF time was (4.0±3.9) years including 13 male. All patients received thoracoscopic surgical ablation including pulmonary vein isolation, left atrial (LA) posterior wall isolation, Waterston's groove Ganglionated plexi ablation by bipolar radiofrequency ablation clamp and LA appendage removal, Marshall ligament dividing. Then establishing LA 3D-modeling, based on LA 3D voltage mapping, catheter ablation was conducted to reinforce surgical ablation or modification in order to confirm bidirectional blocking. Meanwhile, LA ridge and mitral isthmus ablation was performed, some patients received LA anterior wall and tricuspid isthmus ablation. The patients were followed-up at 3, 6 and 12 months after the procedure. Results: 13 patients were restored to sinus rhythm after the procedure and no operative complications occurred. The average follow-up time was (12.1±11.5) months. 2 patients with recovered sinus rhythm had re-catheter ablation since atrial flutter at 3 months post-procedure and sinus rhythm was restored. The overall success rate was 86.7% (13/15), no patient had anti-arrhgthmia medication. Conclusion: Hybrid thoracoscopic ablation and catheter ablation have been a minimally invasive, safe and effective method in treating the patients of long-standing persistent AF.

Objective: To observe the effects of electroacupuncture (EA) with three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) on the apoptosis of neurons and c-Jun N-terminal kinase (JNK) signaling pathway in the hippocampus of rats with vascular dementia (VD), and explore the mechanism of EA intervention for VD. Methods: Fifty male Sprague-Dawley rats were randomly divided into a model group, a sham operation group, a 100 Hz EA group, a 2 Hz EA group, and a 2 Hz/100 Hz EA group, with ten rats in each group. The VD model rats were established by repeated ischemia-reperfusion of bilateral common carotid arteries. The rats in the EA groups received EA intervention at Baihui (GV20), Dazhui (GV14), Geshu (BL17) and Zusanli (ST36), once a day for 14 d. Afterward, Morris water maze was used to examine the learning and memory performances of the rats in each group, hematoxylin-eosin staining to observe the histomorphological changes in the hippocampal CA1 region, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling to test the apoptosis of neurons in the hippocampal CA1 region, and Western blot to detect the protein expression levels of JNK, phosphorylated JNK (p-JNK), Caspase-8, and Caspase-3 in the hippocampus tissue. Results: Compared with the sham operation group, the escape latency of the model group in water maze test was prolonged; the number of crossing the original platform was decreased (P<0.01); the hippocampal neurons were severely damaged and the number of surviving neurons was decreased (P<0.01), whereas the number of apoptotic neurons was increased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were significantly increased (P<0.01). Compared with the model group, the escape latency of each EA group was significantly shortened; the number of crossing the original platform was significantly increased (P<0.01); the damage of hippocampal neurons was alleviated, the number of surviving neurons was increased (P<0.01), and the number of apoptotic neurons was decreased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were decreased (P<0.01). The results in the 2 Hz EA group and the 2 Hz/100 Hz EA group were superior to those in the 100 Hz EA group. Conclusion: EA with the three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) can improve the learning and memory performances in VD rats subjected to ischemia-reperfusion, its mechanism may be related to the inhibition of neuronal apoptosis and the regulation of the related protein expression of JNK signaling pathway, and the intervention effects of EA with 2 Hz and 2 Hz/100 Hz are more significant.

OBJECTIVETo retrospectively evaluate the results of deep sternal wound infection (DSWI) after cardiac surgery.
METHODSBetween January 2010 and September 2013, 139 patients suffering from DSWI after median sternotomy. The incidence of DSWI was 0.47% (139/29 574). There were 111 (79.9%) male and 28 (20.1%) female patients. The mean age was (61 ± 11) years, the mean body weight was (74 ± 14) kg. The incidence of postoperative DSWI was 0.88% (91/10 341) after isolated coronary artery bypass grafting (CABG), 0.70% (15/2 143) after valve surgery or other cardiac surgery plus CABG, 0.21% (24/11 429) after valve surgery, 0.15% (3/2 002) after thoracic aortic surgery, and 0.19% (6/3 158) after congenital heart disease. The sternotomy was re-opened and extensive debridement of the wound was performed in all patients. When the wound was clean and there was a bed of fresh granulation tissue, the sternum was rewired. The surgical procedure performed included debridement, drainage, sternal wire reclosure and pectoralis major muscular transpositions depended on the clinical condition of the patient.
RESULTSThe in-hospital mortality was 9.3%. Failure of secondary sternal refixation appeared in 15 (10.8%) patients, the reoperation procedure of these 15 patients was pectoralis major muscular transpositions. Other complications included sepsis in 13 patients, perivalvular leakage in 3 patients, and cardiac rupture during the surgical procedure in 3 patients. The mean hospitalization was (39 ± 30) days.
CONCLUSIONDeep sternal wound infection is a life-threatening complication after cardiac surgery associated with high morbidity and mortality.
