1.Thinking about improving the cross-cultural communication capacity of the teaching foreign language on Chinese medicine
Chinese Journal of Medical Education Research 2011;10(9):1047-1049
The purpose of foreign language teaching in Chinese medicine is not only translation,but also clearly the role and the purposes of translation.Inputing a culture to another culture is not culture exchange,but cultural coagulation.Expressions with modem scientific system allow speculative natural philosophy freed from the ancient Chinese-style paper into the theory expressed by modem scientific language in order to solve the problems of teaching foreign languages of traditional Chinese medicine texts.

Chinese Journal of Biologicals 2025;38(09):1035-1042
Objective To synthesize an iron-based metal organic framework(MOF) material and investigate its adjuvant effect on immune response in mice. Methods The iron-based MOF material was synthesized via the hydrothermal reaction method, of which the morphology and composition were characterized by transmission electron microscope(TEM), scanning electron microscope(SEM), dynamic light scattering particle analyzer(DLS), X-ray photoelectron spectrometer(XPS), and specific surface area analysis(Brunauer Emmett Teller, BET). Using ovalbumin(OVA) as immunogen, 20 female BALB/c mice were randomly divided into iron-based MOF + OVA group(60 μg iron-based MOF + 20 μg OVA), Alu + OVA group(50 μg Alu+ 20 μg OVA), OVA group(20 μg OVA), and blank group(0. 9% normal saline), and were injected intramuscularly through the lateral thigh at 0, 14 and 28 d, respectively, with 100 μL/mouse. Blood samples were collected from the tail vein at 7, 21 and42 d after the initial immunization, the serum was separated, and the specific IgG antibody level was determined by ELISA.At 42 d after the initial immunization, the levels of specific IgG subtype antibodies in serum, IFNγ secreted by splenocytes,as well as IFNγ, IL-2 and IL-4 secreted by CD4~+T and CD8~+T cells were detected by ELISA, ELISPOT and flow cytometry,respectively. The body mass of mice at 0, 7, 14, 21, 28, 35, and 42 d after the initial immunization was measured, and the behavior of mice in various groups was observed. Results The synthesized iron-based MOF material exhibited a spherical morphology, an average particle size of approximately 129. 4 nm, a specific surface area of 16. 7 m~2/g and a pore diameter of7. 73 nm, containing C, N, S and Fe elements with more content of Fe element. At 42 d after the initial immunization, there was no significant difference in IgG level between iron-based MOF + OVA group and Alu + OVA group(F = 1. 00, P > 0. 05),but IgG2a and IgG2b levels increased significantly in iron-based MOF + OVA group(F = 16. 90 and 16. 57, respectively,each P < 0. 05);the level of IFNγ secreted by spleen cells increased significantly(F = 19. 47, each P < 0. 05);the level of IFNγ secreted by CD4~+T cells increased significantly(F = 14. 94, P < 0. 01), but that secreted by CD8~+T cells had no significant difference(F = 1. 00, P > 0. 05), and the levels of IL-2 and IL-4 secreted by CD8~+T cells increased significantly(F =100. 00 and 945. 80, each P < 0. 001). During the whole immunization process, there were no abnormal behaviors such as depilation or refusal to eat, and the body mass of mice in various groups changed little. Conclusion The prepared iron-based MOF material is simple to synthesize, stable in structure with nano-scale size, which can elicit humoral and cellular immune responses in mice, and is expected to become a new vaccine adjuvant.

Acta Pharmaceutica Sinica 2011;46(4):400-5
Based on the report of previous clinical study which showed cholinergic receptor antagonist scopolamine had antidepressant activity, this study was to investigate the antidepressant activity of scopolamine and explore its effective dose in mice, and to evaluate the effect of scopolamine on the central nervous system and learning/memory ability at its antidepressant effective dose. Tail suspension test, forced swimming test, step-down passive avoidance test and open field test were used to evaluate its effects on mice. Compared with the vehicle control group, single-dose administration of scopolamine (0.1-0.4 mg x kg(-1), ip) significantly decreased the immobility time (P < 0.01 or P < 0.001) in tail suspension test, and significantly decreased the immobility time (P < 0.001) in forced swimming test, but had no effect on the step-down latency and errors in step-down passive avoidance test. Scopolamine (0.1 and 0.2 mg x kg(-1), ip) had no influence on the locomotor activity in open field test, while at dose of 0.4 mg x kg(-1) significantly increase the locomotor activity. These results showed that scopolamine produced reliable antidepressant effect at doses of 0.1 and 0.2 mg x kg(-1), without impairment on learning and memory, as well as excitory or inhibitory effect on central nervous system in mice.

8.SMAD7 prevents heterotopic ossification by regulating endothelial-mesenchymal transition after Achilles tendon imjury
Chinese Journal of Tissue Engineering Research 2017;21(8):1178-1185
BACKGROUND: The endothelial-mesenchymal transition is known to play a central role in the pathological process of heterotopic ossification. OBJECTIVE: To verify the inhibitory effect of SMAD7 on endothelial-mesenchymal transition such as myofibroblast transformation and to explore whether it is a potential target for heterotopic ossification.METHODS: A lentivirus overexpressing SMAD7 was contructed and the optimal titre and transfection efficiency in rat aortic endothelial cells were determined. The lentivirus was then injected into a rat model of Achilles tendon injury, while the controls were given the injection of normal saline. Expressions of endothelial and mesenchymal markers at the injured site were analyzed by quantitative PCR and western blot assay. The heterotopic ossification was observed radiologically and histologically.RESULTS AND CONCLUSION: Local injection of SMAD7-delivering lentivirus resulted in an upregulation of CD31 and VE-cadherin, and a downregulation of N-cadherin and vimentin, suggesting that the endothelial-mesenchymal transition is blocked due to local SMAD7 overexpression. The inhibitory effect became more evident at 10 weeks than at 6 weeks after modeling. Radiology and histological staining further confirmed that the ossified structures in the tendon tissue disappeared after injection of SMAD7-delivering lentivirus, as opposed to the control group. These data suggest that local overexpression of SMAD7 can prevent postoperative heterotopic ossification with no effect on wound healing.
