Objective:To find absorbable adhesives with suitable bonding properties for the absorbable polylactic acid root canal post. To test and compare the bond strengths of absorbable polylactic acid root canal post with three different adhesives. Methods:The absorbable polylactic acid root canal posts were used to restore the extracted teeth, using 3 different adhesives: cyanoacrylates, fibrin sealant and glass ionomer cement. The teeth were prepared into slices for micro-push-out test. The bond strength was statistically analyzed using ANOVA. The specimens were examined using microscope and the failure mode was divided into four categories:cohesive failure between absorbable polylactic acid root canal posts and adhesives, cohesive failure between dentin and adhesives, failure within the adhesives and failure within the absorbable polylactic acid root canal posts. Results:The bond strength of cyanoacrylates [(16. 83 ± 6. 97) MPa] and glass ionomer cement [(12. 10 ± 5. 09) MPa] were significantly higher than fibrin sealant [ ( 1 . 17 ± 0 . 50 ) MPa ] , P <0 . 001 . There was no significant difference between cyanoacrylates and glass ionomer cement (P =0. 156). In the group of cyanoacrylates, the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 25 . 0%, the cohe-sive failure between the dentin and the adhesives was 16. 7%, the failure within the adhesives was 33. 3%, and the failure within the absorbable polylactic acid root canal posts was 25 . 0%. In the group of fibrin sealant , the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 66 . 7%, the cohesive failure between the dentin and the adhesives was 22 . 2%, the failure within the ad-hesives was 11. 1%. In the group of glass ionomer cement, the cohesive failure between the absorbablepolylactic acid root canal posts and the adhesives was 87. 5%, the failure within the adhesives was 12. 5%. The major failure mode in fibrin sealant and glass ionomer cement was the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives. No major failure modes were found in the group of cyanoacrylates. Conclusion:The bond strength of fibrin sealant is low, which cannot meet the requirement of clinical use. The bond strengths of cyanoacrylates and glass ionomer cement are suitable for clinical use. The cyanoacrylates are a kind of absorbable adhesive which has suitable bonding proper-ties for the absorbable polylactic acid root canal post.

Human Interleukin-11 (hIL-11) is a multifunctional cytokine which plays an important role in regulating the proliferation and differentiation of cells in the hematopoeitic,lymphoid system etc. To obtain the IL-1 1 cDNA, a primary culture of Chinese fetal lung fibroblast was prepared from fresh tissue. Then the human IL-11 cDNA without the N-terminal signal peptide sequence was cloned by RT-PCR from the cells induced by PMA. The sequnce indicated that there are three bases different from those previously reported,but with no change of the amino acids. The cDNA was inserted into the 3′ end of trxcA gene in thioredoxin gene fusion expression system pTRXFUS to construct the trxA and hIL-1 1 fusion expression vector, and expressed in E. coli. The fusion hIL-11 accounts for more than 20 % of the total bacteria proteins.The expression product is present in soluble forms and has the full biological and immunological activities.

Objective To evaluate the value of 18F-FDG PET/CT in preoperative diagnosis and staging of suspected extrahepatic cholangiocarcinoma (EHCC).Methods The clinical data of 116 patients (72 males,44 females;age range 26-89 years) with suspected EHCC from January 2013 to October 2014 were retrospectively analyzed.All patients received preoperative whole body 18F-FDG PET/CT scan.The imaging results were compared with final clinical diagnosis.The diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 18F-FDG PET/CT were calculated.Two-sample t test was applied to compare lesion SUVmax of malignant and benign diseases.One-way analysis of variance was applied to compare SUVmax of highly,moderately and poorly differentiated tumors.x2 test was used to compare the difference of diagnostic sensitivities for hilar cholangiocarcinomas and common bile duct tumors.Results All patients were confirmed by exploratory laparotomy and subsequent histologic examination.A total of 94 cases (93 adenocarcinomas and 1 squamous carcinoma) were confirmed malignant and 22 cases (11 biliary calculi,9 cholangitis,1 choledochal cyst,1 tuberculosis) were confirmed benign.The diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 18F-FDG PET/CT for primary tumor were 61.7％ (58/94),77.3％ (17/22),92.1％ (58/63),32.1％ (17/53),64.7％ (75/116),respectively.The diagnostic sensitivity and specificity for regional lymph node metastasis were 45.5％(15/33),91.4％(53/58),and those for distant metastasis were 3/4,94.3％(82/87).The SUVmax of malignant tumors were higher than that of benign lesions (4.57± 3.75,2.72± 2.48;t =2.83,P＜ 0.05),while the differences of SUVmax among highly,moderately and poorly differentiated tumors were not significant (4.89±4.75,4.23±2.49,4.47±2.73;F=0.269,P＞0.05).18F-FDG PET/CT showed a lower sensitivity in hilar cholangiocarcinomas than that in common bile duct tumors,while no statistical significance was observed:48.6％ (17/35) vs 69.0％ (40/58),x2=3.827,P＞0.05.Conclusions The value of 18F-FDG PET/CT in preoperative diagnosis and staging of EHCC is limited.It can distinguish some benign diseases from malignant tumors,but with higher false positive for cholangitis.It can help to adjust treatment strategies by detecting distant metastasis.

AIM: To examine the relationship between corneal lymphangiogenesis and hemangiogenesis after keratoplasty.METHODS: Nineteen human corneas were obtained from 19 patients undergoing a second corneal transplantation in Zhongshan Ophthalmic Center in 2005. Blood and lymphatic vessels in human transplanted corneas were identified by lymphatic vessel endothelial receptor(LYVE-1) and platelet endothelial cell adhesion modecule-1(PECAM-1) immunohistochemistry, and double enzyme-histochemistry; then the association of corneal blood vessel counting (BVC) with lymphatic vessel counting (LVC) was examined.RESULTS: Corneal hemangiogenesis was present in 12 cases (63%), and lymphangiogenesis occurred in 5 cases (26%) of human transplanted corneas. In addition, corneal lymphangiogenesis was only present in vascularized corneas. LVC was strongly and positively correlated with BVC(r=0.725;P<0.01).CONCLUSION: Corneal lymphangiogenesis develops after keratoplasty, and strongly associates with hemangiogenesis.

OBJECTIVETo evaluate the capillary isoelectric focusing (CIEF) method for the estimation of blood hemoglobin A2 (Hb A2) concentrations in routine thalassemia screening.

METHODSA total of 105 samples from healthy adults and 93 samples with positive phenotypes were collected by routine thalassemia screening. CIEF was compared with Helena spife combo electrophoresis system for Hb A2 measurement and its precision and reproducibility were tested by analyzing intra-assay or inter-assay coefficient of variations(CVs). The reliability and veracity of Hb A2 measurement by CIEF for the detection of alpha- and beta- thalassemia including Hb E were evaluated by genotyping of 93 consecutive samples for routine thalassemia screening.

RESULTSBy us e of CIEF for measurement of Hb A2 in a local healthy adult population, the range of reference value(3.59%-5.23%) was obtained. The results of CIEF showed good linearity relation to that of conventional Hb electrophoresis assay. All thalassemia carriers (43 cases of alpha-thals and 44 of beta-thals) or Hb E carriers (6 cases) presumptively identified by the present CIEF for the quantification of Hb A2, combined with routine RBC parameters for indicating microcytosis and hypochromia were confirmed to be the heterozygous or compound heterozygous defects of alpha- or beta- globin gene by molecular diagnosis, without any false positive or false negative results.

CONCLUSIONThe measurement of Hb A2 by CIEF method is rapid, precise and reproducible; it could be used in routine screening for alpha- or beta- thalassemia.
