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.

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.

Objective To summarize the experience of the simple neuroendoscopic endonasal transsphenoidal surgery for the large pituitary adenoma and discuss it's application value.Methods Seventy-eight cases of the large pituitary adenoma treated by simple neuroendoscopic endonasal transsphenoidal surgery from July,2011 to May,2014 were analyzed retrospectively.Tumors were resected using 0 and 30 degree endoscope after opening the same side of the anterior wall of the sphenoidal sinus and sellar bone using the abrasive drilling during operation.Results The tumor removal was total in 62 (79.49％),subtotal in 12 (15.38％),major in 3(3.85％) and part in 1 (1.28％).Seventy-one cases were followed up for 2 months to 2 years after operation and no recurrence was founded,the symptoms of headache disappeared in 49 cases;The vision of patients was improved in 47 cases,menstruation resumed in 12 cases;The acromegaly of patients reduced in 21 cases.Hormone level review of PRL returned to normal in 32 cases,GH returned to normal in 21 cases,ACTH returned to normal in 2 cases.Conclusion The endoscopic transsphenoidal surgery for large pituitary tumors is the safely,minimally invasive surgical techniques.With the development of endoscopic equipment constantly updated and the operational flexibility and comfort is improved ceaselessly,endoscopic transsphenoidal surgery for the sellar tumor will be carried out more widely.

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.

Objective To investigate the efficacy and safety of the minimally invasive percutaneous surgery in the treatment of thoracolumbar fracture combined with posterior ligament injury.Methods The 94 cases of thoracolumbar fracture combined with posterior ligament injury who were admitted into our hospital from Septenber 2012 to January 2016 were selected and equally divided into the observation group and the control group(47 cases in each group) according to different methods.Patients of the observation group were treated with short segment of minimally invasive percutaneous surgery,while patients of the control group were underwent single segment of minimally invasive percutaneous surgery.Recorded the outcomes and prognosis of the two groups.Results There was no significant difference in the operation time and blood loss between the two groups(P ＞ 0.05).The postoperative volume of drainage and the length of stay in the observation group were significantly shorter than those in the control group(P ＜ 0.05).The JOA score of the observation group 1 month after operation was significantly better than that of the control group(P ＜ 0.05).The incidence of complications including pedicle screw breakage,pedicle screw loosening,incision infection,and pulmonary infection in the observation group was 4.3％,which was significantly less than 21.3％ in control group (P ＜ 0.05).The Cobb's angle of the obervation group and control group 1 month after operation were (8.55 ± 1.34) ° and (16.30 ± 2.33) ° respectively,which were significantly lower than (32.19 ± 1.98) ° and (32.08 ± 2.08) ° before operation (P ＜ 0.05).And the Cobb's angle 1 month after operation in the observation group were significantly lower than that of the control group(P ＜ 0.05).Conclusion The short segment of minimally invasive percutaneous surgery for the treatment of thoracolumbar fracture combined with posterior ligament injury can reduce the incidence of postoperative complications,promote the patient's rehabilitation,correct the kyphosis and promote the recovery of neural function,which was safer and more efficient.

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.

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.
