Objective:To explore a method for setting up three dimensional finite element model of posterior glass fiber reinforced composite resin-bonded-fixed-partial dentures (GFRC-RBFPD) including restoration, periodontal tissue and alveolar bone. Methods:A stone model was fabricated including abutments and pontic of restoration, then it was scanned with laser scanner. Acquired data were integrated in Geomagic 5.0. Basic 3D geometric model was established. Different parts of abutement and prosthesis were designed in I-DEAS 10 NX Series and Geomagic, then periodontal tissue and alveolar bone were set up in Geomagic 5.0. Completed 3D geometric model was input into MSC.Marc Mentat 2003 for mesh generation. Boundary conditions were defined. Model was calculated in Mentat 2003. Results:3D geometric model and finite element model including GFRC-RBFPD, abutments, periodontal membrane and bone (bone lamina dura,cortical bone and cancellous bone) were established.Little contour information was lost, comparability between models was improved.Conclusion:The 3-dimensional laser scanning technique, CAD and mesh generation technique are effective in the establishment of 3-dimensional finite element model of GFRC-RBFPD.

Objective To assess the incidence,risk factors and mortality of acute kidney injury(AKI)in patients with chronic myelogeneous leukemia(CML)after myeloablative allogenetic hematopoietic stem cell transplantation(HSCT). Methods Renal function in 93 CML patients undergone myeloablative allo-HSCT was retrospectively analyzed by the RIFLE criteria. Results Thirty-nine patients (41.9%) developed AKI at a median of 40 days after allo-HSCT, including 24 AKI-R patients(25.8%), 10 AKI-I patients(10.8%) and 5 AKI-F patients (5.4%). The morbidity of AKI in patients with ≥Ⅲ acute graft-versus-host disease (aGVHD) and without ＜Ⅲ GVHD was (81.82±11.63)% and (36.59±5.32)% (P=0.0037)rospectively. The morbidity of AKI in patients with increased total bilirubin and without increased total bilirubin was (72.73±13.43)% and (37.04±5.37)%(P=0.0192) respectively. ≥Ⅲ aGVHD was peor-prognostic factor of AKI and RR was 2.773 [95%CI (1.073-7.167), P=0.035]. RR of AKI-I and AKI-F in patients with ≥Ⅲ aGVHD was 6.320195%CI (1.464-27.291), P=0.013]. The mortality within 100 days after allo-HSCT of patients with AKI was significantly different as compared to patients without AKI (P=0.001). Six-mouth survival rates of different class AKI patients after myeloablative allo-HSCT were (86.96±7.02)% (AKI-R), (70.00±14.49)% (AKI-I), 0 (AKI-F) (P=0.000)respectively. Conclusions AKI is one of the main complications in CML patients after myeloablative allo-HSCT. ≥Ⅲ aGVHD and increased total bilimbin are poor-prognostic factors of AKI, and higher morbidity of AKI-I and AKI-F can be found in patients with ≥Ⅲ aGVHD. With the deteriorated AKI, 6-month survival is decreased. RIFLE criteria is sensitive to the early diagnosis of renal function. Moreover RIFLE can monitor the progression of AKI and predict the clinical outcome.

Objective To analyze morbidity and prognosis of acute kidney injury (AKI) in patients with acute leukemia after myeloablative allogenetic hematopoietic stem cell transplantation (HSCT).Methods Renal function and related clinical data in 66 patients receiving myeloablative alloHSCT were retrospectively analyzed.Renal function was evaluated by RIFLE criteria,which defines AKI as three grades of severity-risk (AKI-R),injury (AKI-I) and failure (AKI-F).Results Thirtyseven recipients (56.1%) developed AKI at a median of 29 days after allo-HSCT,including AKI-R(19 recipients,28.8 %),AKI-I (11 recipients,16.7 %),AKI-F (7 recipients,10.6 %).Compared with baseline value,serum creatinine level in the recipients was significantly increased at the 21st day after transplantation (P＜0.05).During 100 days after HSCT,the morbidity of AKI-F in recipients with HVOD and without HVOD were respectively (55.56 ± 22.22)% and (9.01 ± 4.75)% (P＜0.01).The morbidity of AKI in recipients with or without increased total bilirubin was respectively (68.75 ± 24.54)% and (8.38 ± 4.17)% (P＜0.01).The morbidity of AKI in recipients with or without increased CsA concentration was respectively (66.67 ± 10.29) % and (44.44 ± 8.28) % (P＜0.05).100-day survival rate in recipients after myeloablative allo-HSCT without AKI,with AKI-R,AKI-I and AKI-F was respectively (89.66 ± 5.66) %,(83.88 ± 8.54) %,(81.82 ± 11.63) % and (42.86 ± 18.7) % (P＜0.05).Conclusion AKI is one of the main complications in patients with acute leukemia after myeloablative allo-HSCT.The influence of different class AKI on the mortality was different.The earlier diagnosis,prophylaxis and treatment of AKI by the RIFLF criteria might increase the survival rate in recipients with HSCT.

Objective To explore the efficacy of endoscopic sphincterotomy with small incision combined with balloon dilatation (sEST+EPBD)in the treatment of patients with choledocholithiasis and juxtapapillary duodenal diverticula (JPDD).Methods From January 2011 to January 2015 ,149 patients with choledocholithiasis and JPDD who underwent endoscopic retrograde cholangio-pancreatography (ERCP)were enrolled.Among them,60 patients were in sEST+EPBD group and 89 were in endoscopic sphincterotomy (EST)group.Success rate of ERCP and first-time stone removal,changes of total bilirubin (TBil)and direct bilirubin (DBil)levels,as well as the incidence of postoperative complications between the two groups were compared.Chi-square test or t-test was performed for statistical analysis. Results The ERCP success rate sEST+EPBD group was 100.0% (60/60),and the first-time success rate of stone removal was 91 .7%(55/60);correspondingly,ERCP success rate of EST group was 98.9%(88/89),and the success rate of first-time stone removal was 77.5 %(69/89).There was no statistically significant difference in success rate of ERCP between the two groups (χ2 =0.19,P =0.410).The first-time success rate of stone removal of sEST +EPBD group was higher than that of EST group,and the difference was statistically significant (χ2 =5 .53,P =0.020).After operation,the TBil level of sEST+
EPBD group was (152.62 ±109.04 )μmol/L,which was lower than that before operation ((266.02 ± 143.31)μmol/L),and the difference was statistically significant (t =4.88,P <0.01 ).After operation, the DBil level of sEST +EPBD group was (87.13 ±65 .90)μmol/L,which was lower than that before operation ((175 .70 ± 100.53 )μmol/L),and the difference was statistically significant (t = 5 .71 ,P <0.01).After operation,the TBil level of EST group was (251 .90 ±247.90)μmol/L,which was lower than that before operation ((340.20 ±176.20 )μmol/L),and the difference was statistically significant (t=2.74,P <0.05).After operation,the DBil level of EST group was (168.10±140.60)μmol/L,which was lower than that before operation ((228.40 ±139.60 )μmol/L),and the difference was statistically significant (t = 2.87,P = 0.005).The complication rate of sEST + EPBD group after operation was 8.3%(5/60),which was lower than that of EST group (20.2%,18/89 ),and the difference was statistically significant (χ2 =3.88,P =0.049 ).Conclusion sEST+EPBD could increase the first-time success rate of stone removal in patients with choledocholithiasis and JPDD,and it is a safe and effective treatment.
