This paper presents a unit free-form deformation (FFD) method applied to rapid three-dimensioanl (3D) bone reconstruction, which was based on traditional FFD. With the femur as an example, we reconstructed a 3D model of femur from two X-ray images and a standardized model by taking advantage of unit FFD algorithm. The X-ray images and its parameters were taken by C-arm device. Those parameters and X-ray contour are contributed to 3D reconstruction. The out contours of X-ray image and standard model were connected by point matching algorithm. The unit-FFD lattice was built to reconstruct standard model and finally made the contour of X-ray image and standard model exactly the same. Experiments on shape accuracy, robustness and time consuming, carried out by 35 specimen from cadaver, showed that mean error of shape (0. 52 mm) and mean construction time (112 s) were lower than those using traditional method (0.7-2.6 mm, 8-20 min). The method proposed in this paper shows a good prospect in clinical application and related research.

Background Excessive elongation of axis and expansion of sclera is one of the hot topics in the study of the pathogenesis of high myopia.To establish a human scleral fibroblasts (HSFs)-collagen matrix culture model is helpful for understanding the reciprocal and adaptive interactions between HSFs and the collagen matrix in tissue.Objective The aim of this study was to establish a HSFs-seeded collagen three-dimension culture system that may mimic the sclera remolding in myopia.Methods HSFs were isolated and cultured from donor eyes by explant culture and purified by passages culture in vitro.The expressions of vimentin and keratin in the cells were detected by immunofluorescence technique to identify the cells.Rat tail tendon was obtained from 8-week-old SPF SD rats to prepare the collagen matrix.The mixed solution of 400 μl collagen matrix and 1 100 μl PBS,200 μ1 nutrient medium,50 μ1 NaOH and HSF suspension were mixed to prepare the collagen gel three-demension culture system.The growth and morphology of the cells in the culture system were observed under the inverted phase contrast microscope,and IPP-5 software was used to measure the contraction area of collagen gel,and the mechanical creep properties of the HSFs-seeded collagen matrix were measured by a biomechanics test instrument.Results HSFs emigrated from tissue 7 days after culture and passage could be performed 14 days after culture.The expression of keratin was absent in HSFs,while vimentin was positively expressed.The free-cell collagen gel was clear and unchanged in the experimental duration.However,the cells were obviously increased on the three-demension culture system and showed a tissue-like structure of net-like arrangement on dozens of layers.In 7-14 days after culture,the collagen gel area in a three-demension collagen matrix revealed a decrease of 90％.Duotriode-like and fusiform cells were seen 24 hours after culture.The biomechanical creep curve of HSFs-seeded collagen matrix consisted of the nonlinear section (0-100 seconds) and linear section (100-600 seconds),and the former appeared to be an elastic change of the gel under the temporal stress,and the latter was the creeping of the gel with the time.Conclusions Rat tail collagen appears to have a good biocompatibility to HSFs.HSFs-seeded collagen matrix can retain the mechanical creep properties,and it may be a good tool for the study on the relationship between HSFs and extracellular matrix or intercellular biological behaviour for scleral remodeling.

Objective To explore the pancreatic kininogenase enteric-coated tablets in the treatment of diabetic retinopathy (DR) patients and its effect on the optic disc and macula retinal hemodynamics. Methods 86 cases (140 eyes) of DR patients were randomly divided into pancreatic kininogenase group and normal group with 43 cases in each group, two groups were treated with basic therapy, pancreatic kininogenase group were combined with pancreatic kininogenase treatment. The best corrected visual acuity and the clinical effect of optic disc and macula retinal hemodynamic changes were compared between two groups. Results After treatment, the best corrected visual acuity (BCVA) in pancreatic kininogenase group was greater than the normal group (P<0.05), the retinal neovascularization and fluorescein leakage area in pancreatic kininogenase group was less than the normal group (P<0.05). The disc vascular and macular retinal blood flow volume (VOL), blood flow velocity (FLW)values in pancreatic kininogenase group were larger than those of normal group, and the clinical curative effect of pancreatic kininogenase group was better than that of normal group (P<0.05). Conclusion Pancreatic kininogenase enteric-coated tablets in the treatment of DR patients can improve the optic disc and macular retinal hemodynamic parameters, improve visual acuity and reduce the retinal neovascularization and fluorescein leakage area, so as to improve the clinical treatment effect.

Objective To investigate the level of caregivers′burden and the coping style among parents of cancer children. Methods Totally, 229 parents of cancer children participated in the investigation by Chinese version of zarit burden interview (ZBI), Chinese version of coping health inventory for parents (CHIP) and self-designed general information questionnaire. The associations between caregivers′burden and coping styles were tested by Spearman correlation analysis. Results The caregiver′s burden on the parents was in the middle level with a total score of (30.50 ± 12.24). The coping style the parents took most frequently was to unite the family and keep a positive attitude and regard it as most effective. The caregiver′s burden was negatively associated with the positive coping style . Conclusion The parents of cancerous children suffer from middle level of burden . Nurses should assess the caregiver′s burden, provide targeted interventions to relieve it, help the to establish effective coping style and change their psychological and mental state and ultimately improve their quality of life.

Objective To investigate the level of CD73 expression in CD4+ regulatory T(Treg) cells in patients with systemic lupus erythematosus ( SLE ) and explore its role in the pathogenesis of SLE.Methods We selected 29 untreated/active SLE patients and 22 healthy controls. Frequencies of CD4+ CD25+CD73+ T cells and levels of FOXP3 protein expressed in CD4+ CD73+ CD4+ CDhi25, CD4+ CDhi25, CD4+ CD25+ T cells were analyzed by flow cytometry. Meanwhile, the levels of SLE disease activity index ( SLEDAI), C reactive protein (CRP), ESR,immunoglobulin and complement were measured. Results The percent of CD4+ CD25+ CD73+ T cells was decreased in new-onset SLE compared with healthy controls[(1.25±1.32) % vs (2.35±1.09) %, P ＜0. 01], and it had no correlation with the levels of SLEDAI, CRP, ESR, et al and anti-C1qand anti-nucleosome antibodies ( P ＞ 0.05 for each). Both in groups of new-onset SLE and healthy controls, CD73 level expressed in CD4+ CDhi25CDhi25T cells[(29.05 ± 12. 53)%, (43.35 ± 10. 09)%]was higher than that expressed in CD4+ CD25+ T cells[( 17.48 ± 6. 92 ) %, ( 29. 98 ± 10. 39 ) %, P ＜ 0.01]. In both SLE patients and healthy controls, levels of FOXP3 protein expressed in CD4+ CD73+ T cells[(65. 36 ± 14. 40)%,(63.80±14.05)%]and CD+4 CDhi25CD4+ CDhi25 T cells[(67. 30 ± 13.04)%, (56. 30 ±9. 21 )%]were higher than those in CD4+ CD25+T cells[(45.70 ± 12. 74)%, (43.98 ±5. 17)% ,P ＜0. 001], while it had no significant difference between the CD4+ CDhi25CD4+ CDhi25 and CD4+ CD73+ T cells(P＞0.05). Conclusion These results demonstrate that CD73 may be a new surface marker of regulatory T cells, and the abnormal expression of CD73 in Treg cells may participate in the pathogenesis of SLE.

Objective To clone, express Tp0319 gene from Treponemapallidum (T. pallidum), and to assess the immunocompetence of recombinant protein. Methods The immuno-dominant region of Tp0319gene was chosen by computer analysis, amplified from T. pallidum complete genome by PCR, subcloned into the expression vector pQE32 to construct a recombinant plasmid, pQE32/Tp0319, which was then expressed in E. coli M15. The recombinant protein was purified with Ni-NTA affinity chromatography, and identified by using sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and Western blot. New Zealand rabbits were immunized with the recombinant protein, and the titer of anti-Tp0319 antibodies in sera from immunized rabbits were measured with indirect ELISA. Also, indirect ELISA with the recombinant Tp0319 as coating antigen was performed to detect the anti-Tp0319 antibody in sera from 200 normal human controls and 200 patients with syphilis. Results The prokaryotic expression vector pQE32/Tp0319 was constructed successfully, and the recombinant protein Tp0319 with a molecular weight of about 30 000 was attained. Specific humoral response was elicited by the recombinant protein in New Zealand rabbits and the specific antibody titer was more than 1: 10 240 after immunization for 3 times. Western blot proved that the recombinant protein could specifically react with anti-T. pallidum IgG antibody-positive sera. Indirect ELISA was successfully developed with the recombinant Tp0319, and detected antibodies to T. pallidum in control sera with a sensitivity and specificity of 100% (40/40), respectively. Compared with T. pallidum particle agglutination (TPPA) assay, the sensitivity and specificity of the indirect ELISA were 92.6% and 100%, respectively, in the detection of T. pallidum in sera from patients and controls, and the concordance between the indirect ELISA and TPPA was 96%. Conclusions The prepared recombinant protein shows a satisfactory immunocompetence, which may lay a foundation for its further application in the serodiagnosis of syphilis.
