Objective: To study clinical application value of dobutamine stress echocardiography (DSE) and nitroglycerin stress single photon emission computed tomography (SPECT) for evaluation of restenosis after percutaneous coronary intervention (PCI). Methods: A total of 39 patients after PCI were examined by DSE and SPECT one week before coronary angiography (CAG). Dose incremental program of dobutamine included five levels:5μg•kg-1•min-1, 10μg• kg-1• min-1, 20μg•kg-1•min-1, 30μg•kg-1•min-1, 40μg•kg-1•min-1, and each level maintained for three minutes. Sensitivity, specificity and accuracy of DSE and SPECT were determined according to CAG examined result and examined results were compared between DSE and SPECT. Results: Compared with CAG, SPECT and DSE were no significant differences (P>0.05)in sensitivity (83.3% vs. 75.0%) and accuracy (71.8% vs. 87.2%) for evaluating restenosis after PCI, but compared with SPECT, DSE possessed higher specificity (66.7% vs. 92.6%). Conclusions: Dobutamine stress echocardiography is accurate, and its specificity is better than that of SPECT for evaluating restenosis after percutaneous coronary intervention.

BACKGROUND: Hip arthroplasty and internal fixation with intramedullary cannulated screws are mainly used for senile femoral neck fractures. However, osteoporosis can usually lead to failure in internal fixation.OBJECTIVE: To analyze the joint function after fixed with intramedullary cannulated screws in elderly patients with femoral neck fractures, and to explore the factors related to functional recovery.METHODS: Clinical data of 89 patients with femoral neck fractures undergoing internal fixation with intramedullary cannulated screws after 2-year follow-up were analyzed retrospectively. The sex, age, Garden type, bone mineral density, body mass index, screw distribution, reduction index, operation time, bearing time and Harris hip scores were analyzed. Rank related analysis and accumulative Logistic regression analysis were performed on SPSS18.0 software. RESULTS AND CONCLUSION: (1) Normal Q-Q plot and normality test results indicated that the Horris scores in all patients after 2-year follow-up presented with skewed distribution (P=0.000). (2) Rank related analysis showed that age,Garden type, bone mineral density, and reduction index were related with Harris score (P < 0.05 or P < 0.01). (3) Accumulative Logistic regression analysis showed that the independent variables including age, Garden type, bone mineral density, and reduction index made significant effect on Harris hip scores. (4) To conclude, age, Garden type,bone mineral density, and reduction index are important factors for functional recovery of the hip after fixed with intramedullary cannulated screws.

Objective To evaluate the palatal rugae individual-specific properties and stability before and after orthodontic treatments for investigating the reliability of palatal rugae for individual identification of forensic dentistry based on the palatal rugae model ananlysis. Methods Maxillary models of 70 patients were obtained before and after orthodontic treatments respectively. Palatal rugae morphologic changes and individual identification were examined by model analysis including changes in number, orientation, shape, and length of palatal rugae, as well as mesial and distal endpoint displacement in the anterioposterior(AP) and mesiodistal (MD) direction. Furthermore, The examination of palatal rugae average match accuracy(%) was performed between the pre-treatment and post-treatment orthodontics models and post-treatment and duplicated post-treatment orthodontics models. Results ① The palatal rugae morphological changes were found and the incidence of palatal rugae changes were showed in length(28.6%), segmenta-tion(4.3%); unification(2.9%); orientation(1.4%) and shape(1.4%) after orthodontic treatment. Also the displacement of the distal endpoint of palatal rugae was 45.7% for anterioposterior indirection, 40% for mesiodistal indirection after orthodontic treatment, while the anterioposterior displacement of the mesial endpoint of palatal rugae was 32.9% and mesiodistal displacement was 17.1%. ② The identical palatal rugae patterns were not found both the pre-treatment and post-treatment groups. ③ The palatal rugae average match accuracy was 92.19% between pre-treatment and post-treatment groups, however, the rate had increased by 99.05% when matching the palatal rugae patterns of post-treatment groups to their duplicates. Conclusion Palatal rugae patterns have the high specific properties to each indivi-dual. Although there are some changes in morphology of palatal rugae after orthodontic treatment, it still can be used as a novel method for individual identification in forensic dentistry.

OBJECTIVETo analyze the influence of optimal codon usage on the expression levels and immunogenicity of DNA vaccines, encoding the human papillomavirus type 6b (HPV 6b) E7 gene.
METHODSThe full length E7 gene of HPV 6b was modified to substitute human preferred codon for rarely used codon, and three mutations were introduced into the pRB binding site of HPV 6b E7 to eliminate its transformation potential. The codon optimized and mutated E7 gene (hu-mE7) were cloned into the Kpn I and EcoR I site of the pcDNA3 mammalian expression vector, the in vitro expression of the hu-mE7 gene and the immunogenicity of hu-mE7 DNA vaccine were compared with the wt-E7gene.
RESULTSThe in vitro expression of pcDNA3-hu-mE7 was much higher than the classical wt-E7 plasmid in monkey COS-1 cell line. Mice immunized intramuscularly with the pcDNA3-hu-mE7 showed that the codon modified E7 gene induced a stronger IFN-gamma ratios than the wt-E7 gene.
CONCLUSIONSThese results suggest that the optimized codon usage contributes to the enhancement of gene expression and immunogenicity of HPV 6b E7 gene.
