Objective To investigate the genetic stability, immunogenicity and protective efficacy of AdC68-rab. gp, a novel rabies vaccine based on the replication-defective chimpanzee adenoviral vector AdC68-ept. Methods The recombinant adenovirus AdC68-rab. gp expressing the glycoprotein of rabies vi-rus ERA strain was constructed. Genomes of the AdC68-rab. gp of different generations were extracted and analyzed. HEK293 and Huh7 cells were infected with the AdC68-rab. gp of different generations. ICR mice were immunized with the AdC68-rab. gp and blood samples were collected 4 weeks or 6 months after immuni-zation. Rapid fluorescent focus inhibition test ( RFFIT) was performed to detect the neutralizing antibody against rabies virus in mice serum samples. ICR mice were challenged with lethal dose of rabies virus 4 weeks after the immunization with AdC68-rab. gp to evaluate the protective efficacy of AdC68-rab. gp. Re-sults The genome of AdC68-rab. gp was stable after 15 passages, which was identical to that of the 5th and 1st generations. High levels of neutralizing antibody against rabies virus in serum samples were detected in mice immunized with AdC68-rab. gp and maintained for a long period of time. Immunization mice with one dose of AdC68-rab. gp could protect all mice from the lethal dose challenge of rabies virus. Conclusion The novel AdC68-rab. gp was characterized by good genetic stability and ideal protective effi-cacy. The adenoviral vector based vaccine could be further developed as a potential candidate for the substi-tute of current rabies vaccine.

By combing the domestic and foreign papers on patient ethical responsibility education, this paper summarized the educational elements of patient ethical responsibility education, including the educational subject, educational object, educational content, and educational path. At present, there are limitations in the research on patient ethical responsibility education both domestically and internationally, such as incomplete theoretical system, insufficient empirical research on the transformation from theory to practice, and the lack of educational effectiveness evaluation tools. It is expected to provide useful reference to improve the theoretical system of patient ethical responsibility for future research on patient ethical responsibility education, explore the path of ethical responsibility education and practice, and formulate effective tools for evaluating the effectiveness of ethical responsibility education, and improve patients’ awareness and performance of ethical responsibility.

Objective:To analyze students' learning behavior in the teaching practice of the presentation-assimilation-discussion (PAD) class based on Xuexitong platform.Methods:The PAD class based on Xuexitong platform was applied to the course of child and adolescent health in the specialty of preventive medicine. And the data were collected from the platform to analyze students' learning behavior, including the number of visits and its rules, the completion rate and duration of homework submission, the completion rate of task points, and the number of students participating in discussions. Questionnaires were used to investigate students' evaluation of the learning effect. SPSS 17.0 was used for Mann-Whitney U test, Kruskal Wallis H, and Chi-square test. Results:A total of 99 students visited the platform 40 322 times over 84 days, with a peak on the day of the discussion class, with the highest number of visits from 16:00 to 20:00, and 29.3% (29/99) of them visited the platform for less than 40 days. The completion rate of homework submission was 98.0% (582/594), with 31.1% (181/582) of the person-times less than 6 hours of homework submission duration. The completion rate of task points was 99.0% (3 919/3 960), and the number of students participating in discussions was 3 (2,7). In total, 86.9% to 90.9% of the students thought that the five aspects of learning effect were partly or basically achieved.Conclusion:Students' learning behavior is good on the whole, but their participation in discussion is few, and some of them learn passively, which needs to be further improved.

Objective: To investigate the effects of oxidized low-density lipoprotein/β2 glycoproteinⅠ/β2 glycoproteinⅠantibody (oxLDL/β2GPⅠ/β2GPⅠ-Ab) complex on the phenotypic transformation and lipid transpoters on the surface of rat thoracic aorta smooth muscle cell line (A7r5), and their correlation with toll-like receptor 4 (TLR4) signaling pathway. Methods: A7r5 cells were stimulated by oxLDL, oxLDL/β2GPⅠ complex, oxLDL/β2GPⅠ-Ab complex, β2GPⅠ/β2GPⅠ-Ab complex and oxLDL/β2GPⅠ/β2GPⅠ-Ab complex respectively, and then total RNA and protein were collected. The expressions of α-smooth muscle actin (α-SMA), macrophage surface marker CD68, galectin-3 (LGALS3), scavenger receptor class B member 3 (CD36) and ATP-binding cassette transporter A1/G1 (ABCA1/ABCG1) were detected by real-time quantitative PCR (RT-qPCR), western blot and immunofluorescence (IF) respectively. The roles of TLR4 and its downstream signaling molecules in the phenotypic transformation and expression changes of lipid transporters of A7r5 cells induced by oxLDL/β2GPⅠ/β2GPⅠ-Ab complex were investigated by the pretreatment of TLR4 blocker TAK-242 (5 μmol/L) or c-Jun N-terminal kinases 1/2 (JNK 1/2) blocker SP600125 (90 nmol/L). Results: The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex significantly increased the levels of CD68 and LGALS3, and decreased the level of α-SMA, while TAK-242 could reverse this phenomenon. The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex could promote the expression of CD36 and inhibit the expression of ABCA1/ABCG1, while TAK-242 and SP600125 could reverse this process. Conclusion The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex promotes the phenotypic transformation of A7r5 cells to macrophage-like cells, regulates the expression of lipid transport-related molecules and enhances the ability of lipids transport into cells. TLR4 and JNK1/2 are closely related to this process.

Objective: To investigate the effects of β2 glycoprotein Ⅰ/anti-β2 glycoprotein Ⅰ complex (β2/aβ2) on oxidized low density lipoprotein (oxLDL)-mediated lipid accumulation and focal adhesion kinase (FAK) activation in THP-1 macrophage, as well as the role of Toll-like receptor 4 (TLR4) during the process. Methods: THP-1 cells were differentiated into THP-1 macrophage by PMA (100 ng/mL). THP-1 macrophages were treated with RPMI 1640 medium, oxLDL, oxLDL+β2/aβ2 or oxLDL+lipopolysaccharide (LPS). The mRNA expressions of lipid transportation molecules, ACAT1, ABCA1 and ABCG1 were detected by RT-qPCR. Intracellular total cholesterol (TC) and free cholesterol (FC) in THP-1 macrophages were evaluated by Trinder assay, then the content and proportion of intracellular cholesteryl ester (CE) were calculated. The expression and phosphorylation of FAK were detected by immune fluorescence, RT-qPCR and western blot. To evaluate the role of TLR4, THP-1 macrophages were pre-treated with or without TLR4 inhibitor TAK-242 (1 μg/mL). Results: β2/aβ2 treatment significantly inhibited oxLDL-mediated lipid accumulation and FAK expression and phosphorylation in THP-1 macrophages, which could be reversed by TLR4 blockage. Conclusion β2/aβ2 inhibits the oxLDL-mediated lipid accumulation and FAK activation of THP-1 macrophage, which is related to the function of TLR4.

OBJECTIVE To explore the regulatory mechanism of compatibility of ginseng and gecko dispensing granule on kidney yang deficiency model rats. METHODS Male SD rats were randomly divided into normal group （no modeling ，no administration），model group （modeling，no administration ），Jinkui shenqi pill group （modeling，dose of 2.33 g/kg），ginseng group（modeling，dose of 0.53 g/kg），gecko group （modeling，dose of 0.21 g/kg）and compatibility group （modeling，ginseng 0.53 g/kg and gecko 0.21 g/kg）. The body mass and anal temperature of rats were measured at different time points ；the serum levels of cAMP ，cGMP，CRH，ACTH，CORT，T，T3，T4，E2，IgG and IgM were measured ；the pathomorphological changes of adrenal gland ，thyroid gland and testis were observed ；mRNA expression of CRH ，thyroid stimulating hormone releasing hormone （TRH）and gonadotropin releasing hormone （GnRH）in hypothalamus were detected.
