Translational medicine, characterized by multi-disciplinary cooperation, is a new research area focusing on patients. Although translational medicine is still in its early stages in China, it has attracted increasing attention. To apply translational medicine, it is essential to implement the principles and methods of systematic biology to break the inherent barriers between basic and clinical science. Moreover, it is important to update research ideas, strengthen the transformation of scientific and technological achievements, and construct public library research resources and exchange platforms.

BACKGROUND:Silicon plays an essential role in bone development and bioactive silicate glasses pioneered the current era of bioactive materials. Various biomaterials have been developed based on the biological function of silicon. OBJECTIVE:To explore the biological function of silicon and research process of silicon in biomaterials. METHODS: A computer-based retrieval of CNKI, PubMed, SpringerLink and Elsevier ScienceDirect databases was performed to search the relevant literatures concerning the biological function of silicon and its application in biomaterials. Al data were primarily screened to exclude repeated and irrelevant articles. Literatures about the application of silicon in biomaterials were included. RESULTS AND CONCLUSION:A total of 68 eligible English articles are enroled. Silicon plays important chemical and biological roles in bone. Silicon in the extracelular matrix interacts with glycosaminoglycans and proteoglycans during their synthesis and form ionic substitutions in the crystal lattice structure of hydroxyapatite. In addition, the dissolution products of bioactive glass (mainly silicic acid) expose significant influence on the molecular biology of osteoblasts in vitro, and can regulate the expressions of several genes including osteoblastic markers, cel cycle regulators and extracelular matrix proteins. Silicon has been proved to improve the bioactivity of numerous materials and do no harm to their mechanical properties and without cytotoxicity.

With the progresses of the research on "Digital Human", more and more information has been needed for the setting up of the three-dimensional digital models of human organs. In the present paper, based on the method of block mapping with a normal-style bump mapping method, we normalized the vector of the surface of the models, computed offset of the texture coordinates and added to them. The projection of the coordinates to the tangential space complemented the disturbance to the vector of models' surface. The method was proposed with bump texture mapping on the surface of the biological models of organs to improve the impression of the visualization of the organ models and to enhance the sense of reality of the models.

Objective To discuss the value of percutaneous compression plate (PCCP) in treating intertrochanteric fractures. Methods A retrospective study was done on 57 patients with intertrochanteric fractures treated by PCCP from January 2008 to January 2009 to evaluate the operative effect.Results All the fractures were healed in 11-15 weeks after the operation, with no incision infection, hematoma, internal fixation failure or fracture collapse. Two surgical incisions were for 2 cm, with no blood transfusion found in any patient. According to Harris score, the postoperative excellent rate reached 92.6%. Conclusion PCCP can attain similar effect wiht DHS and now is the choice of treatment in treating intertrochanteric fracture in the elderly patients.

ObjectiveToexploretheeffectof ceremideonprocess of peritoneal mesothelial cells(PMCs) apoptosis induced by peritoneal dialysis solution(PDS).Methods PMCs were cultured with normal DMEM,1.5% PDS and 4.25% PDS.4.25% mannitol was used as high osmotic pressure control.Ceremide were detected by LC-MS-MS.Flow cytometry was used in apoptosis analysis.Bax,p53 and bcl-2 protein expressions were detected by Western blotting.Results (1) PDS caused the increase of intracellular ceremide in PMCs,and normal and high osmotic pressure controls had no such effect.As the acidic sphigomyelinase inhibitor,desipramine significantly inhibited the production of ceramide induced by 4.25% PDS [(56.08±12.24) μg/L vs (91.25:t:15.89) μg/L,P<0.01]. (2) Compared with 1.5% PDS,4.25% PDS stimulated PMCs apoptosis (26.65%±6.21% vs 4.04%±1.86%,P<0.01),up-regulated bax and p53 proteins expression (P<0.01),and down-regulated bcl-2 protein exprssion(P<0.05).Desipramine obviously inhibited the apoptosis induced by 4.25% PDS,decreased bax and p53 proteins expression,increased bcl-2 protein expression(P<0.05).Exogenous C2-ceremide reversed the effect of desipramine(P<0.05).Conclusion The increase of intracellular ceremide may play an important role in the PMCs apoptosis induced by high glucose PDS.

ObjectiveTo investigate the preventive strategy of early post-operative complications of closed spinal dysraphisms in children.MethodsOne hundred and nine children with closed spinal dysraphisms underwent surgery from January 2004 to December 2008,were enrolled in this study.After dural closure,the wound was washed completely with saline to clear the tissue debris to prevent postoperative infection. We routinely made a horizontal incision to prevent postoperative infection. Results After operation,all patients were recovered and were discharged from hospitalNo post-operative complications,including cerebrospinal fluid leakage, wound infection and flap necrosis, were encountered. ConclusionThe sophisticated microsurgical technique and the delicate surgical manipulation is the prerequisite for the prevention of early operational complication of closed spinal dysraphisms in children.

Objective To explore the value of multiple-mouse MRI in evaluating the therapeutic effect of endostatin for transplantation tumor models of colorectal carcinoma in mice.Methods 24 subcutaneously transplantation tumor’s models of colorectal carcinoma (CT-26) in mice were established, 1 week later, 16 tumor-bearing mice were sieved out and divided randomly into two groups: endostatin (ES) group and normal saline (NS) group, treated with intraperitoneal injection of endostatin 6 mg/kg?d 0.2 ml and equal volume of saline respectively for 14 days. Subsequently, MMMRI was performed, and then the mice were killed immediately and the tumors were cut into sections which were stained with hematoxylin and eosin (H&E). Results Subcutaneous fat layer in NS group presented thinner or disappeared on T1WI,while subcutaneous fat layer in ES group presented thicker. The tumors presented inhomogeneous high signal and intratumoral stippled necrosis on T2WI. The tumor’s volumes measured by MRI and pathology were(2723.26?1136.91) mm3 and (3505.76?1350.12) mm3 respectively,there was no difference between these two measures. And there was correlation between MRI results and pathological results. There was no difference of absolute signal intensity between ES group and NS group on T1WI and T2WI. The signal intensity ratio of ES group (3.19?0.28) was higher than which of NS group (2.60?0.47) on T2WI, and there was no difference on T1WI. Conclusion The therapeutic effect for endostatin on transplantation tumor models of colorectal carcinoma in mice can be displayed distinctly in MMMR image, and the inhibition rate of results can be displayed exactly and noninvasively.
