The rutile structure titanium oxide (Ti-O) film was prepared on the pure titanium material TA2 (99.999%) surface by the magnetic filter high vacuum arc deposition sputtering source. The method can not only maintain the material mechanical properties, but also improve the surface properties for better biocompatibility to accommodate the physiological environment. The preparation process of the Ti-O film was as follows. Firstly, argon ions sputtered to the TA2 substrate surface to remove the excess impurities. Secondly, a metal ion source generated Ti ions and oxygen ions by the RF discharge. Meanwhile a certain negative bias was imposed on the sample. There a certain composition of Ti-O film was obtained under a certain pressure of oxygen in the vacuum chamber. Finally, X-ray diffraction was used to research the structure and composition of the film. The results showed that the Ti-O film of the rutile crystal structure was formed under the 0.18 Pa oxygen partial pressure. A Nano scratch experiment was used to test the coating adhesion property, which demonstrated that the film was stable and durable. The contact angle experiment and the platelet clotting experiment proved that the modified surface method had improved platelet adhesion performance, and, therefore, the material possessed better biocompatibility. On the whole, the evaluations proved the modified material had excellent performance.

Objective To establish an animal model of sciatic nerve firearms injury in rabbits Methods All of 26 rabbits were divided into A, B, C, D and E groups at random The hit point was the middle point of the body surface projection of sciatic nerve in the right thigh The rabbits were injured with the type 53 musket by balls of 0 38 g and 1 03 g and with the dynamite amounts of 0 35 g, 0 65 g, and 1 20 g The injury velocity of ball was detected, and the transmission energy of steel ball was calculated The pathological changes of sciatic nerve were observed with light and electron microscopy Results In group A, B and D, typical pathological changes occurred In group B, resulting from a ball of 0 38 g and dynamite of 0 65 g, the primary velocity was (939 8?16 0) m/s, the mean transmission energy was (80 0?8 5) J Conclusion Animals inflicted with a type 53 musket with a ball of 0 38 g and dynamite of 0 65 g show typical sciatic nerve injury in a steady situation and can serve for experiment usage

Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.

Objective To investigate the mechanism of renal damage due to rupture of atheroselerotic plaque of renal artery in apolipoprotein E (ApoE) knock-out mice. Methods The model for atherosclerotie renal artery stenosis (ARAS) was established by using ApoE knockout mice. The model mice with renal artery stenosis <50% were divided into the plaque rupture group and the non-plaque rupture group. Wild-type C57BL/6J mice were used as the control group. All the mice were raised under the same conditions. The renal arteries and kidneys were collected for the following analysis. Nuclear factor-kappa-Bp65 (NF-kBp65), intercellular adhesion molecule 1 (ICAM-1) and P-selectin (P-sel) were determined by Western blotting. The expression of interleukin 6 (IL-6) mRNA was detected by RT-PCR. Immunohistochemistry was performed by using serial sections to detect F4/80-related macrophages. Urine n-acetyl-β-d-glucosaminidase (NAG) activity was determined by direct enzyme-substrate coloration. Results In comparison with the nonplaque rupture group and the control group, the expression of NF-kBp65 protein in the blood, renal artery and kidney increased significantly in the plaque rupture group (P<0.05). The expression of F4/80, ICAM-1, P-sel, and IL-6 mRNA were increased significantly in the plaque rupture group (P<0.05), as compared with the non-plaque rupture group and the control group. The Ser and the activity of urine NAG in the plaque rupture group were higher than those in the non-plaque rapture group. The expression of NF-KBp65 protein differed insignificantly between the control group and the non-plaque rupture group (P>O.05). The group differences in the expression of F4/80, ICAM-1, P-sel, and IL-6 mRNA were similar to those in the expression of NF-KBp65 protein. The group differences in the activity of urine NAG and the Scr were similar to those in the expression of NF-kBp65 protein. Conclusion Rupture of atherosclerotic plaque of renal artery causes renal pathology change and renal function damage, which is mediated by inflammation.

Objective To prospectively assess the therapeutic procedure and outcome of MR-guided percutaneous sclerotherapy in patients with venous vascular malformations of the extremities. Methods Fifty-seven percutaneous sclerotherapy treatments were performed under MR guidance in 28 patients with venous vascular malformation. Assessment was conducted to analyze (1) individual success of therapy, (2) improvement of clinical symptoms, ( 3 ) occurrence of complications, (4) volume changes at follow-up examinations, (5) contrast-to -noise ration (CNR) changes. Paired-t test was used to compare the volume and CNR of pre- and postintervention. Results All MR-guided percutaneous sclerotherapy were performed successfully and without serious complications. Individual predominant symptoms were improved, especially about the pain and functional impairment. The mean lesion volumes of pre- and post-intervention were (56. 8 ± 11.7 ) cm3 and ( 27.0 ± 7.2 ) cm3 respectively, which showed significant difference ( t = 8. 90, P < 0. 01 ). The percentage of volume shrinkage ranged from 28. 5% to 74. 4% [ mean ( 54. 4 ± 5. 3 ) % ]. The CNR of the pre and post-interventional images were 21.9 ± 2. 0 and 8.4 ± 0. 9 respectively. There was significant difference(t = 21.76, P < 0.01 ) between them, and the percentages of CNR decrease were 40.0% to 78. 0% [ the mean(61.0 ± 3.6)%]. Conclusion MR-guided sclerotherapy of venous vascular malformations of the extremities is a safe and efficient technique.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
