The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.

①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。

Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.

Estrogen deficiency can increase the mRNA expression of MMP-1、MMP-3 and IL-1β in OA synovia tissue. Estrogen could inhibit the mRNA expression of MMP-1、 MMP-3 and IL-1β in OA synovia tissue. Progestin could even decrease this expression. Estrogen could slightly increase the mRNA expression of TIMP-1. It is suggested that low dose of estrogen supplement play a protective effect on OA cartilage, and progestin could increase this protective effect.

Results: 1 Tritiated thymidine incorporation assay showed that 1μM adenosine plus coformycin slightly inhibited CTLL-2 proliferation, while 5-20μM adenosine elicited marked inhibition on CTLL-2 proliferation responded to IL-2 a dose-dependent fashion. 2 Coformycin alone could also inhibit CTLL-2 proliferation at the concentration of 2.5μM. The underlying reason maybe due to the endogenous adenosine produced by CTLL-2 cells.

结果：11μM腺苷对CTLL-2增殖仅有轻微的抑制作用，而5、10、20μM腺苷的存在可显著抑制CTLL-2的增殖，并且呈剂量相关，P值均小于0.05.2CTLL-2经过2.5μM助间型霉素的单独处理也可引起轻度的增殖受抑现象，分析其可能原因是T细胞自身可以分泌腺苷，所以该抑制现象的出现与内源性腺苷有关。3本实验所用腺苷浓度对CTLL-2的活细胞百分率影响轻微。
