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.

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.

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.

This article focused on summarization of the available new screening technology for traditional Chinese medicine (TCM) new drug, including high throughput screening (HTS), biological chip, molecular biological chro-matography, high content screening (HCS), network pharmacology, proteomics, and computer-aided drug design (CADD).

Objective To investigate the antimicrobial resistance and genotype distribution of staphylococcal cassette chromosome mec (SCCmec) of staphylococcus aureus (S.aureus) isolated from children hospitalized at Pediatric People's Hospital of Zhongjiang County.Methods Seventy-seven strains of S.aureus were collected by nasopharyngeal swabs at the Pediatric Department of People's Hospital of Zhongjiang County from January to December 2015.Methicillin-resistant staphylococcus aureus (MRSA) and methicillin-susceptible staphylococcus aureus (MSSA) were identified by cefoxitin disc diffusion and detection of mecA method.The minimum inhibitory concentrations (MIC) of antibiotics were determined by E-test method.SCCmec typing on MRSA strains was performed by using multiplex PCR.Results MRSA accounted for 54.5％ (42 strains) strains of 77 strains.All MRSA strains were resistant to Penicillin,and the rates of antibiotic resistance to Cefuroxime,Ceftriaxone,Erythromycin were 78.6％,95.2％ and 97.6％,respectively.The rates of antibiotic resistance of 35 MSSA to Penicillin and Erythromycin were 97.1％ and 62.9％,and they were also sensitive to other antibiotics.In 42 strains of MRSA,SCCmec type Ⅳa was the predominant type (27 strains,64.3 ％),which was followed by type Ⅳ g and Ⅴ (each 5 strains,11.9％),type Ⅳ c and Ⅳh (each 1strain,2.4％).Non-susceptibility rate of SCCmec Ⅳ to cefuroxime was significantly higher than that of other SCCmec types (P ＜ 0.05).Conclusions All strains from children hospitalized in People's Hospital of Zhongjiang County are often resistant to Penicillin and Erythromycin.The proportion of MRSA isolated from hospitalized children was high.SCCmec type Ⅳa is the main genotype of MRSA.

Though Runx2 and Osterix are both key transcription factors in the pathway of osteoblast differentiation, whether Runx2 positively regulates Osterix being unknown. It was showed that Runx2 induced the gene expression of Osterix both in the non-osteoblastic cell lines, either pluripotent or differentiated, and in the osteoblastic cell lines. At the same time, the results also indicated that Runx2 up-regulated the activity of the 3.2 kb human Osterix promoter. Further experiments identified a highly conserved and functional Runx2 binding site "AGTGGTT" within the promoter. Thus the results support the hypothesis that Runx2 is involved in the regulation of the Osterix gene expression. Moreover, the transient transfection and dual-luciferase assay showed Osterix up-regulated the activity of the 2.3 kb type Ⅰ collagen promoter in the non-osteoblastic cells, but Runx2 did not. This difference implies that Osterix, the down stream transcription factor of Runx2 during osteoblast differentiation, is needed to stimulate the osteoblast-specific gene expression of type Ⅰ collagen.
