Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups (n = 90 each): CT group (group C) and Mimics group (group M). The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C (P < 0.05). 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups (P < 0.05). The VAS score was 1.6 ± 0.3 in group C and 1.3 ± 0.4 in group G, there was no statistical significance (P > 0.05) between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.

Objective To study the significance of treating advanced primary hepatic carcinoma by using the different methods combined with chemotherapy. Methods One hundred and fifteen cases with advanced primary hepatic carcinoma were divided into 5 groups by accepting different chemotherapy: the groups of interventional-chemotherapy (group A, 40 cases), whole body hyperthermia combined with chemotherapy (group B, 16 cases), only chemotherapy (group C, 9 cases), local heat chemotherapy (group D, 26 cases), symptomatic supportive (group E, 24 cases) for comparing response rate (RR) and survival time between each other. Results The RR in group A,B,C were 30.5 % (12/40), 12.5 % (2/16), 11.1 % (1/9) respectively, and there was no significant difference among three groups (P>0.05). The mid-survival time of five groups were 7.7, 9.2, 7.9, 6.0, 4.7 months, and there was significant difference between group B and group E (P<0.05). The 0.5-, 1-, 2-year survival rate in group B were higher than those in group E with significant difference (81.2%vs. 29.1%, 37.5%vs. 12.5%, 12.5%vs. 0, all P<0.05). Conclusions The RR of only routine chemotherapy is low, while the RR of interventional-chemotherapy and local heat chemotherapy is high with non-prolonged survival time. Whole body hyperthermia combined with chemotherapy have active effects in helping to improve the efficacy and prolong the survival time in retreatment patients with advanced hepatic tumor.

OBJECTIVE:To determine the therapeutic effect of transpedicular instrumentation without fusion on patients with thoracolumbar burst fractures.METHODS:A total of 63 patients with thoracolumbar burst fractures (the inclusion criteria was neurologically intact spine with a kyphotic angle >20° and/or decreased anterior vertebral body height > 50%) who were treated with transpedicular instrumentation without fusion were studied,including 40 cases treated by AF internal fixation,16 cases by Tennor screw-rod fixation system and 7 cases by Diapason screw-rod fixation.All patients underwent a radiological and clinical assessment (including the loss of kyphotic angle,decreased anterior vertebral body height,the midsagital diameter of the canal and the Low Back Outcome Score) preoperatively,postoperatively and after 24 months.The deformity of angulation was measured by Cobb angle.RESULTS:All pstients were followed for a 24 months,with average stay of 13.4 days.There were averaged 3.8 days from admitted to operation,and the internal fixation was removed within 8-12 months in 51 cases,followed a 9.4-day hospital stay.According to low back outcome score,46 patients achieved excellent,9 good,5 fair and 3 poor,with excellent and good rates of 88%.The Cobb's angle was 20.1° preoperatively,6.2° postoperatively,and 11.9° after 24 months.The average lose of anterior vertebral body height was changed from 49.1% preoperatively to 17.4% postoperatively,which was 20.4% after 24 months.The midsagittal diameters was 49.8% (n=63) preoperatively,78.1% (n=28) postoperatively,and 91.7% (n=25) after 24 months.The implant failure occurred in 5 patients.The radiographic parameters had no associativity to the outcome of LBOS.CONCLUSION:Transpedicular instrumentation without fusion is conductive to treating burst fractures of the thoracolumbar spine without nerve injury.The routine posterior or posterolateral fusion is unnecessary in the operative management of these fractures.

Objective To investigate the incidence of occult pancreatobiliary reflux and to evaluate its relation to gallbladder epithelial dysplasia and cancer. Methods From July 2006 to Feb 2008,956 cases underwent selective biliary procedure or preoperative endoscopic retrograde cholangiopanereatography (ERCP), bile was collected and amylase was measured. All removed gallbladders were pathologically examined for dysplasia and cancer. Results Occult pancreatobihary reflux was found in 75 of 754 patients in this study, with an incidence of 9. 9%. The biliary amylase values in the patients with occult pancreatobiliary reflux and in controls were 7701±20 378 IU/L and 16±51 IU/L, respectively ( P <0. 01 ).Gallbladder dysplasia and cancer were found in 31.0% and 3.4% of the patients with occult pancreatobiliaryreflux, respectively, and both were higher than those in the patients without pancreatobiliary reflux ( P <0. 05). In the patients with occult pancreatobiliary reflux, the biliary amylase level with gallbladder dysplasia or cancer was 2388 ± 2745 IU/L and was higher than those without gallbladder dysplasia or cancer (P < 0. 01 ). Conclusions With an incidence of 9.9% in patients of normal pancreatobiliary junction,the occult pancreatobihary reflux may contribute to the pathogenesis of gallbladder epithelial dysplasia and cancer.

Objective To investigate the safety and effectiveness of different intravenous anesthesia methods for pediatric ERCP . Methods Data of 45 children undergoing ERCP at the Affiliated Hangzhou Hospital of Nanjing Medical University from August 2013 to July 2016, including intravenous anesthesia,the procedure of ERCP, adverse reactions and the waking time were retrospectively studied. Results A total of 45 patients in two groups under intravenous anesthesia successfully underwent ERCP . Seventeen patients ( 37. 8%) whose body weights were over 20 kg and the duration of surgery was predicted less than 30 minutes received deep sedation without airway intubation. Twenty?eight patients ( 62. 2%) with an initial weight of less than 20 kg and the duration of surgery was predicted more than 30 minutes received general anesthesia with airway intubation. In patients with deep sedation, the mean time of waking was 7. 2±6. 3 minutes, body movement reaction occurred in 1 case ( 5. 9%) and with transient decreasing of pulse blood oxygen ( beyond 95%) occurred in 2 cases ( 11. 8%) . In patients receiving endotracheal anesthesia with intubation, the mean waking time was 10. 5±8. 7 minutes without adverse reactions associated with anesthesia. Conclusion Both deep sedation and general anesthesia with airway intubation are safe for pediatric ERCP. However, general anesthesia with airway intubation is an ideal method ensuring the airway safety and oxygen supply for children less than 20 kg undergoing first?time ERCP or the duration of surgery lasting over 30 minutes.
