OBJECTIVEThis study aims to construct a long-term, osteogenesis-targeting HU-308 drug delivery implant by the layer-by-layer electrostatic self-assembly (LBL) technique, and observe the features of its delayed release in vitro.

METHODSA heparin (Hep) and chitosan (Chi) multilayer was coated on pure titanium using the LBL technique, and the titanium implants were dipped into the solution to load HU-308. The amount of loaded drug and release rates were measured using a UV-Vis spectrophotometer. The relationships between the loading efficiency, release time, and multilayer films were evaluated. The morphology of all the multilayers was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM).

RESULTSThe results showed that the Hep/Chi self-assembly multilayer was gradually fabricated on the titanium surface. HU-308 was successfully loaded on the titanium implants. The amount of loaded drug increased with the amount of multilayer films, except in the T20 group. In vitro drug release study showed that drug release was more difficult in the system with thicker films, and large amounts of multilayer films decreased the release speed. Both SEM and AFM measurements showed typical LBL deposition of Hep and Chi.

CONCLUSIONThe HU-308 drug delivery implant is successfully fabricated via LBL technology. It could provide sustained release of HU-308 over 30 d. This type of implant may provide a new possi- bility of promoting implant-bone osseointegration for osteoporotic patients.

According to the theory of microscopic system reform in higher education, a total of 927 college students of different majors from Beijing University of Chinese Medicine were investigated by using SIMPP method. It indicated that through promoting the study of self-prepared, learning state and learning effect, students can enhance their learning ability of the admission acceptance. From the perspective of teachers, the students' self-study ability can be fully mobilized using individual person-alized teaching method. Then, the initiative of university education in the teaching and learning can be improved. Ultimately, the efficiency of student learning can be improved.

Interest in learning can not only stimulate students' enthusiasm for learning, but also directly affect the quality of higher education. In this paper, the questionnaire of the related factors of college students' interest was designed to carry out micro-system engineering research. The factors as-sociated with college students' interest in learning and their complex relationships were investigated by using methods of systems science and systems engineering. The results shows that the students who can actively participate in after-school learning discussions , feel good in lectures and have clear learning objectives, are interested in learning. And at the same time, the teacher's influence and his active guidance in classroom teaching will raise students' interest in learning. This study provides a more comprehensive basis and clues to improve students' interest in learning and education reform.

Objective To discuss the impact of relevant psycho-social factors on the driving adaptability. Methods A total of 870 vehicle drivers were screened out by stratified cluster sampling,and 620 drivers were finally selected for this study after eliminating those who had 1 -2 accidents. The 620 drivers were divided into accident group and non-accident group. Demographic questionnaire, life event scale, SCL-90 Scale and Eysenck Personality Questionnaire were applied to investigate their general condition, life event, mental health and personality. All data were analyzed by t test and stepwise Fisher discriminatory, and then the discriminatory equations of driving eligibility were established. Results The scores of factors including positive life events, negative life events, family events, work events and social events in accident group were 9.62 ± 11.36, 34.53 ± 30.01, 24.05 ± 23.09, 16.78 ± 17. 12 and 2.82 ± 5.07, respectively, which were higher than 4.67 ± 6.25, 6.38 ± 10. 15, 6.48 ± 9.43, 3.96 ±6.55 and 2.02 ± 5.43 respectively in the non-accident group ( P ＜ 0. 01 ). The total SCL-90 score and the scores of all factors in the accident group were higher than those in the non-accident group ( P ＜0. 01 ). The Eysenck Personality Questionnaire scores of the accident group were significantly higher than the non-accident group in N dimension ( 56. 32 ± 8.77 vs. 45.23 ± 8.06 ) and P dimension (52.22 ±10.43 vs. 48.31 ± 9.35 ) ( P ＜ 0. 01 ). Fisher discriminatory equations: Faccident group = 0. 258 × X6 + 0.119 ×X9 +0.637 ×X17 +0.043 × X5-7.476; Fnon-accident group =0. 137 × X6-1. 000 ×X9 + 1.423 ×X17 +0.003× X5-2.601. Total discrimination accuracy of verification was 88.3%, and the total accuracy of prospective discrimination was 88.0%. Conclusions There is clear correlation of driving adaptability with coercion, anxiety, emotion and negative factors. The discriminatory equations are useful for selecting drivers because of high accuracy, and may play an important role in reducing the occurrence of traffic accidents.

Objective To investigate the effect of atorvastatin on the expressions of long non-coding RNA (LncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)and inflammation factors in human umbilical vein endothelial cells (HUVECs) stimulated by high glucose. Methods The expression of MALAT1 in HUVECs incubated with high glucose(30 mmol/L) for different time periods were detected by real-time PCR. Under high glucose condition, the expressions of MALAT1, interleukin-6(IL-6), and interleukin-8 (IL-8) in HUVECs were detected after MALAT1 was silenced by siRNA or atorvastatin was added. Results (1) After HUVECs were incubated with high glucose for different time periods, the expressions of MALAT1 were increased to some extent(P<0.05), with the peak at 12h (P<0.01). The levels of IL-6 and IL-8 expression and secretion were increased after HUVECs were stimulated by high glucose for 12h (P<0.05). (2)The silence of MALAT1 markedly suppressed high glucose-stimulated expression and secretion of IL-6 and IL-8 (P<0.05). (3) Atorvastatin significantly inhibited high glucose-stimulated expressions of MALAT1, IL-6, and IL-8(all P<0.05). Conclusions High glucose induces the secretion of inflammatory factors by stimulating MALAT1 expression in endothelial cells. Atorvastatin significantly inhibits high glucose-stimulated MALAT1 expression and decreases inflammatory reaction.
