Objective To explore denture re-repair method, the key steps and the results. Method The clinical data of the 72 cases with complete denture re-repair were retrospectively malyzed. Results The results of repair of 48 cases were effective( 15 cases with one of titanium palatal care), accounting for 67 percent, repair,23 cases were effective, accounting for 32%, Repair ineffective in 1 case, accounting for 1%. Repair effect of satisfaction with the extent of alveolar bone absorption was no significant relationship between the 72 cases in the mandibular alveolar ridge had the 58 cases of Lowland Technology, accounting for 80%. Conclusions In the process of making dentures,it is necessary to carefully deal with every step to obtain good denture retention. Improve denture retention for denture repair is essential. Repair material selection and a good physician-patient relationship is also a help to enhance effect.

Objective To estimate the diagnostic value of cytology, DNA-ICM(DNA-image cytometry),cytology combined with DNA-ICM for pancreatic malignancy,and to explore the cut-off value for DNA-ICM. Methods Patients with suspicious pancreatic malignancy were retrospectively identified. In total,145 EUS-FNA specimens acquired from 140 separate patients were examined by cytology and DNA-ICM. Diagnostic values among cytology, DNA-ICM and the combination of the techniques in detecting pancreatic malignancy were compared. Results Compared with cytology, DNA-ICM had a lower sensitivity (63.0% VS 82.4%)and accuracy(69.7% VS 85.5%). After combining the techniques, the diagnostic value for pancreatic malignancy significantly improved compared with that by cytology(0.941 VS 0.912, P=0.007 0)or DNA-ICM only(0.941 VS 0.815, P<0.000 1). By using the Youden index, the cut-off value for DNA-ICM to detect pancreatic malignancy was one cell with DI(DNA index)≥2.5. Notably,with this standard, the sensitivity and accuracy of DNA-ICM significantly increased to 72.3% and 77.2%, and those of the combined techniques increased to 91.6% and 93.1%, respectively. Conclusion Automated DNA-ICM is an objective and effective method for pancreatic malignancy. Although DNA-ICM has a lower diagnostic value than that of conventional cytology, an improved value was obtained after combining the techniques.

Objective To investigate the clinical outcome of pancreatic pseudocyst(PPC)treated with non-surgical methods,and to compare the efficacy and safety between percutaneous drainage and endoscopic drainage in the management of PPC.Methods From February 2010 to July 2017,clinical data of patients with PPC,who received percutaneous drainage or endoscopic drainage,were retrospectively analyzed.The symptom relief rate,short-term and long-term radiologic remission rate,complication rate, recurrence rate and length of hospital stay were compared between patients treated by ultrasound guided percutaneous drainage(percutaneous group),by endoscopic ultrasonography-guided drainage(EUS group)and by endoscopic retrograde pancreatography guided transpapillary drainage(ERP group).Two independent samples t test,one-way analysis of variance,non-parametric test and Fisher′s exact test were performed for statistical analysis.Results A total of 153 patients were treated and the operation was successfully conducted in 148 patients(96.7%),of whom 39 were in percutaneous group,73 in EUS group and 36 in ERP group.The median follow-up time was 26 weeks(two weeks to 358 weeks).The symptom relief rate,long-term radiographic remission rate,complication rate,recurrence rate and retreatment rate of percutaneous group,EUS group and ERP group were 87.2%(34/39),79.5%(58/73),80.6%(29/36);81.5%(22/27),88.6%(39/44),66.7%(16/24);17.9%(7/39),28.8%(21/73),16.7%(6/36);15.0%(3/20),13.8%(8/58),10.0%(2/20);and 10.3%(4/39),8.2%(6/73),2.8%(1/36),respectively.There was no statistically significant difference among three groups (all P> 0.05).The short-term radiographic remission rate of ERP group was significantly lower than those of percutaneous group and EUS group(46.7%,14/30 vs 77.1%,27/35 and 87.7%,64/73),and the differences were statistically significant(χ2 =6.442 and 19.450,both P<0.01).The median hospital stay of percutaneous group was longer than those of EUS group and ERP group(14.0 days vs 9.0 days and 8.0 days),and the differences were statistically significant(Z= -3.687 and -2.630,both P<0.01).Conclusions The efficacies of percutaneous drainage and EUS-guided drainage are both better than ERP,and they are effective and safe methods especially for the patients with complication of pseudocysts and necrosis debris in pseudocysts.However,the hospitalization time of percutaneous drainage is longer. In addition,percutaneous drainage can be an alternative method after failed endoscopic drainage.
