BACKGROUND: There are various methods to observe and detect early angiogenesis in the process of entochondrostosis, but each holds certain deficiencies.OBJECTIVE: To explore the possibility of tetracycline and alizarin complexone as an indirect marker ofangiogenesis in the process of entochondrostosis.METHODS: New Zealand white rabbit models of bilateral radial bone defects were prepared, followed by β-tricalcium phosphate implantation, and then given the injection of tetracycline and alizarin complexone at 1 and 15 days,respectively. Samples were collected at 28 days, some of which were observed using fluorescence/light microscope after ink perfusion and hard tissue slicing, and the others were decalcified and observed using immunohistochemistry. The uniformity between lumen structures labeled with bone affinity fluorescein and vascular structures marked by immunohistochemistry and ink perfusion was compared.RESULTS AND CONCLUSION: The lumen structure labeled with bone affinity fluorescein was confirmed to be a CD34 positive vascular structure. Under the fluorescence microscope, the bone affinity fluorescein labeled vascular morphology was consistent with ink perfusion-labeled, and black ink lines could be observed in the lumen structures labeled with bone affinity fluorescein after ink perfusion. In addition, the color of the lumen labeled with fluorescein was more gorgeous,three-dimensional structure more vivid, and the vascular evolution process distinguished more easily by different fluorescein colors, exhibiting unique advantages. Therefore, it is available to detect the early angiogenesis in the process of entochondrostosis.

Objective To assess the effect of anticoagulant drugs,elastic compression stockings(ECS)and(Daflon) on the prevetion of the post-thrombotic syndrome(PTS).Methods Fifty-eight deep venous(thrombosis)(DVT) patients were divided into control group and treatment group I and II.The control group (n=15) did not take anticoagulant drugs or the time of anticoagulant drug administration was less than 1 month,and the use of(ECS) was less than 3 months.The treatment group I(n=24) took warfarin for 6 months and the ECS were used in the follow-up time;the treatment group II(n=19),besides warfarin therapy and ECS,took Daflon for 12 months.All the patients were followed up,the general conditions were assessed with clinical score,and the therapeatic results of the 3 groups were assessed.Results The rate of PTS occurrence in control group was significantly higher than that in treatment group 1 and treatment group 2.At 6 months,the clinical score of treatment groups 1 and 2 was significantly lower than that of control group.At 1 and 1.5 years after discharge,the clinical score of treatment group 2 was significantly lower than that of treatment group 1.Conclusions The long-term comprehensive and systemic therapy(including warfarin,ECS and daflon) for DVT could prevent PTS.
