Rehabilitation medicine is a comprehensive multi-discipline. It is important to use varied Methods , modern and traditional, rationally in teaching rehabilitation medicine to improve the quality and efficiency. Some of these Methods were discussed.

Objective: To construct the prokaryotic expression vector bearing fusion gene NT4-ADNF-9 and lay foundation for further study on genetic therapy of neurosensory deafness. Methods: By means of asymmetrical primer/ template, double stranded cDNA of activity dependent neurotrophic factor-9 (ADNF-9) was obtained, which included restriction enzymes sites on the two extremities. ADNF-9 cDNA was ligated to the signal and leader peptides of neurotrophin 4 (NT4), and the fusion gene was named NT4-ADNF-9. Then it was subcloned into prokaryotic expression vector pBV220, and called pBV220/ NT4-ADNF-9. Results: Evidences of DNA sequence analysis and restriction enzymes digestion showed that we recombined ADNF-9 cDNA to the 3′terminal of the signal and leader peptides of NT4, and the fusion gene was subcloned into pBV220 successfully. Bioactivity of the products was proved that it could support the cell survival and neurite growth in the primary cultures of dorsal root ganglia (DRG) of embryonic day-8 chicken neurons as compared to the control. Conclusion: Prokaryotic expression vector pBV220/NT4-ADNF-9 can be constructed successfully and the bioactivity is satisfactory.

Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.Further,epigenetics and microRNA might be involved in this process.Our review will summarize the most recent findings in each of these areas.

Objective To observe the clinical efficacy of Kuijiening Paste acupoint application on ulcerative colitis (UC) patients of spleen-kidney Yang deficiency type, and its effect on serum levels of IFN-γand IL-4. Methods Sixty UC patients were divided into treatment group, control group and combined treatment group, 20 cases in each group, and were given Kuijiening Paste acupoint application plus placebo, oral sulfasalazine plus comfort paste and Kuijiening Paste acupoint application plus sulfasalazine respectively for 60 days. The clinical efficacy, mucosal lesions efficacy, mucosal pathology efficacy, changes of serum IFN-γand IL-4 were observed after treatment. Results There was no significant difference in clinical efficacy, mucosal lesions efficacy and mucosal pathology efficacy among the three groups (P>0.05). After treatment, IFN-γlevels of the three groups significantly reduced, and IL-4 levels significantly increased (P<0.01). The difference between the treatment group and the control group was significant (P<0.05). The difference between the combined treatment group and the control group was significant (P<0.01). Conclusion Kuijiening Paste acupoint application combined with sulfasalazine can regulate the level of immune cytokine in UC patients of spleen-kidney Yang deficiency type, and receive good clinical efficacy.

Objective To study cell proliferation and apoptosis of renal corpuscle in normal developing mouse.Methods PCNA immunohistochemisty method,terminal deoxynucleotidyl transferase mediated dUTP-biotin nick endlabeling(TUNEL staining method)and light,electron microscopy were used to observe proliferation and apoptosis within corpuscle at different stages of development.Results Nearly all cells in Ⅰ and Ⅱ stages had nuclear PCNA immunolabeling.The number of PCNA immunolabeling cells during Ⅲ and Ⅳ stages was gradually decreased,and to less in Ⅴ stage.TUNEL positive cells could be easily observed before birth and identified in Ⅲ and Ⅳ stages.Electron microscope revealed that the mitotic activity was observed in all cells of Ⅰ and Ⅱ stages renal corpuscles.The mitotic phases of endothelial cells and podocytes could be seen in Ⅲ stage,but only endothelial mitotic activities in Ⅳ stage of renal corpuscle.Apoptotic activities of endothelial cell and Bowman's parietal cell were noted,predominantly in Ⅲ and Ⅳ stages.Conclusion Proliferation and apoptosis exist universally in the course of developing renal corpuscle,and supervise and control the regular development of renal corpuscle cooperatively.

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective To study clinical significance of S-100B protein in umbilical cord blood of asphyxial neonates with hypoxic-ischemic encephalopathy(HIE).Methods Forty-three cases of healthy infants were regarded as control group(group 1).Sixty cases of asphyxial neonates were divided into two groups(44 cases without HIE as group 2;another 16 cases with HIE as group 3).S-100B protein levels in umbilical cord blood of three groups were measured with enzyme-linked immunosorbent assay retrospectively. Results Levels of S-100B protein in group 1,group 2 and group 3 were(1.055?0.356) ?g/L,(1.572?0.533) ?g/L and(2.394?(0.943) ?g/L,) respectively.S-100B protein levels in umbilical cord blood of group 2 and group 3 were significantly higher than that of group 1(t=2.306,7.991 P
