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 evaluate plasma natriuretic peptide brain (BNP) levels in elderly male patients with type 2 diabetes and primary osteoporosis.Methods A total of 122 elderly male patients with type 2 diabetes were divided into 3 groups according to bone mineral density(BMD):normal group (41 cases),osteopenia group (40 cases) and osteoporosis group (41 cases),and another 33 age matched healthy subjects as control group.Plasma BNP levels were determined by ELISA.Results Plasma BNP levels in osteoporosis group [(1.95 ± 0.49) pmol/L] and osteopenia group [(1.64±0.48) pmol/L] were significantly elevated compared with that in normal group [(1.32±0.38) pmol/L] and control group [(1.26±0.39) pmol/L] (all P＜0.01).There was a statistical difference between osteoporosis group and osteopenia group (t=3.539,P＜0.05),and also between normal group and control group (t=2.726,P＜0.05).Plasma BNP levels had negative correlation with BMD of 2na-4th lumbar vertebra (r=-0.366) and femoral neck (r=-0.375),body mass index (r=-0.288) and estrodiol (E2) (r=-0.352) (all P＜0.05); while had a positive correlation with parathyroid hormone (PTH) (r=0.353,P＜0.05).Conclusions With BMD declining,plasma BNP levels are elevated in elderly male type 2 diabetes,which may be related to the compensatory increase in PTH and the decrease in estradiol.

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 Investigate the clinical efficacy of treating retreated smear-positive tuberculosis patients with conventional anti-tuberculosis chemotherapy combined with levofloxacin. Methods Divide 60 retreated smear-positive tuberculosis patients registered in our hospital between October 2012 and October 2014 into two groups using random number table method: levofloxacin group and conventional treatment group. Each group contains 30 patients that were treated for 9 months , and the efficacy the both treatment methods were compared. Results The sputum conversion rate in the levofloxacin group is 93.33% and 96.67% after treating for 6 months and 9 months , respectively; which are substantial higher than that of the conventional treatment group with sputum conversion rate of 70% and 73.33% after 6 months and 9 months of treatment , respectively (P < 0.05). The absorption rate of the levofloxacin group is significantly higher than that of the conventional treatment group (P < 0.05). The cavity improvement rate of the levofloxacin group is 73.33%, which is significantly higher than that of the conventional treatment group (33.33%) (P < 0.05). The clinical efficacy of the LVFX group is substantially higher than the routine treatment group (P < 0.05). The overall effectiveness of LVFX group reached 100% , which is significantly higher than that of the conventional treatment group (86.67%) (P < 0.05). Conclusions Levofloxacin combined with conventional anti-tuberculosis chemotherapy can effectively improve the clinical efficacy in the treatment of tuberculosis.

Objective To investigate the value of theory-practice integrated in the course of medical imaging diagnosis. Methods The teaching method of bone and joint system was adjusted based on theory-practice integration. 212 students of department of medical imaging were divided into group A (95 students, Grade 2009) and group B (117 students, Grade 2010). The traditional teaching method was adopted in group A, and the theory-practice integrated teaching method was adopted in group B. The teaching effect was evaluated by the exam results(theory and experimentation) and ques-tionnaire. SPSS 13.0 software was used and the measurement date were expressed by x±s. Statistical analysis was performed using t test, with the level of test α=0.05. Results The results of theoretical exam (P=0.024),practical exam (P=0.017) and questionnaire of group B was higher than group A (P=0.00). Conclusions LBL、CBL、TBL integrated teaching method is better than traditional teaching method, especially in improving the students' ability of linking up theory with practice, learning initia-tive, teamwork.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

Objective To investigate the effect of high-mobility group box protein1 (HMGB1) on the expression of TNF-αand its mechanism in 16HBE in vitro. Methods groups with different HMGB1 (0, 100, 500, 2 000 ng/mL) concentration was set; RAGE antagonizing groups were as control, HMGB1-2000ng, anti-RAGE and anti-RAGE+HMGB1. The changes of TNF-αmRNA and secretion were determined by quantitative PCR and ELISA. RAGE protein level was measured by western blotting. Results HMGB1 intervention and TNF-α expression of 16HBE presented a positive dose-dependent relationship. Thechanges of RAGE was HMGB1positively concentration dependent. In comparison with HMGB1 2 000 ng/mL group, anti-RAGE+HMGB1showed a remarkable reduction of TNF-α secretion. Conclusion In vitro, HMGB1 increases TNF-α expression in 16HBE with a dose-dependent manner through RAGE.
