Objective To explore the safety of the laparoscopic surgery in radical resection for different stage rectal cancer.Methods Clinical data of 200 cases with rectal cancer underwent laparoscopic radical resection(observation group) were analyzed retrospectively,including 52 cases of stage 0-Ⅰ,148 cases of stage Ⅱ-Ⅲ.Two hundred cases patients with rectal cancer underwent open radical surgery were selected as control group,including 44 cases of stage 0-Ⅰ,156 cases of stage Ⅱ-Ⅲ.The length to distal resection margin,the number of harvested lymph nodes,the incidence of postoperative complications and the prognosis of recent situation were observed,the safety of the laparoscopic surgery was analyzed.Results Whether rectal cancer of stage 0-Ⅰ or Ⅱ-Ⅲ,there were no significant differences in terms of the length of distal resection margin((2.5±0.9) cmvs.(2.4±1.1) cm,t=0.490,P=0.625;(3.1±1.0) cm vs.(3.2±1.3) cm,t=0.749,P=0.454),the number of harvested lymph nodes((12.3±4.2) vs.(12.7±3.9),t=0.480,P=0.632;(13.9±5.4) vs.(15.1±4.9),t=2.369,P=0.118),the incidence of postoperative complications (17.3％ vs.18.2％,x2 =0.012,P=0.911;27.7％ vs.28.8％,x2=0.049,P=0.825),the rate of local recurrence(1.9％vs.2.3％,x2 =0.014,P =1.000;4.1％ vs.3.2％,x2=0.157,P=0.692),the distant metastasis (3.8％ vs.2.3％,x2=0.195,P=1.000;5.4％ vs.4.5％,x2=0.137,P=0.712) and 3-year survival rate (96.2％vs.95.5％,x2=0.010,P=0.808;83.8％ vs.85.3％,x2=0.132,P=0.714) between the observation group and control group (P＞0.05).Conclusion For rectal cancer of stage 0-Ⅰ,laparoscopic surgery has good safety,and worthy of popularization and application.For rectal cancer of stage Ⅱ-Ⅲ,due to its operation for a long time as well as the possible risk in postoperative anastomotic fistula,the implementation of laparoscopic surgery should be more cautious.

Objective To explore the value of preoperative spleen-liver volume ratio (SLVR) for predicting recurrence of primary liver cancer after hepatectomy.Methods Clinical data of 86 cases of hepatocellular carcinoma undergoing hepatectomy were analyzed retrospectively from January 2009 to December 2014.According to the preoperative SLVR,these patients were divided into two groups:SLVR ＜ 0.8 group (low SLVR group) and SLVR≥0.8 group (high SLVR group).Patients were followed-up until June 2015.Cox ratio risk pattern analysis was used for the recurrent correlative factors.Results The 1-,3-,and 5-year survival rates were 95.5％,88.6％,and 81.8％ in the low SLVR group,and 73.8％,47.6％,and 40.5％ in the high SLVR group,respectively.The difference were statistically significant between two groups (P ＜0.05).Cox regression analysis revealed that SLVR≥0.8,AFP-L3％ ≥10％,the maximum diameter of the tumor ＞ 5 cm,and hepatic or portal vein tumor thrombus were independent predictors of poor disease-free survival after hepatectomy for hepatocellular carcinomas (P ＜ 0.05).Conclusions Preoperative SLVR≥0.8 is an independent adverse predictor of poor disease-free survival.

Objective To investigate the effects and mechanism of Sufentanil on Hep3B cell viability in liver cancer.Methods Sufentanil of different concentrations (0.01,0.1,1,5,10,1 5 μmol/L)was used to treat Hep3B cells.The changes of cell cycle,apoptosis and protein expression were detected to explore the potential mechanisms by MTT method,flow cytometry and Western blot,respectively.Results Reduced viability of Hep3B cells,arrested cell cycle in the G0/G1 phase,decreased expression of survivin protein,and increased expression of caspase-3 protein were observed with the increase of Sufentanil concentration. Conclusion Sufentanil inhibited the viability of Hep3B cells through affecting cell cycle,promoting cell apoptosis and changing protein expressions of survivin and caspase-3.

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.
