Functional bone tissue engineering scaffold used to repair tuberculosis bone defect / 中国组织工程研究

BACKGROUND:Repairing tuberculosis bone defect has become a research focus with the development of anti-tuberculosis functional bone tissue engineering scaffold. OBJECTIVE:To evaluate the preparation, drug release performance and osteogenic properties of the anti-tuberculosis functional bone tissue engineering scaffold. METHODS:PubMed, Chinese Journal Ful-text Database, Wanfang databases were searched by computer for articles addressing functional bone tissue engineering scaffold for repair of tuberculosis bone defect. The keywords were“bone tissue engineering scaffold;tuberculosis;bone defect”in English and Chinese. RESULTS AND CONCLUSION:The anti-tuberculosis functional bone tissue engineering scaffold has good drug delivery, biocompatibility, osteogenic properties and anti-tuberculosis properties. As a good choice to avert bone defect relapse, the scaffold enables a long and stable drug release into bone defects to enhance the therapeutic efficacy of anti-tuberculosis drugs topical y. Given the technical deficiencies, we can only combine two drugs with the anti-tuberculosis bone tissue engineering scaffold, although the combined use of three or four anti-tuberculosis drugs is preferred. Additional y, a complete course of anti-tuberculosis treatment often lasts for 6-12 months, which cannot be achieved by the existing anti-tuberculosis bone tissue engineering scaffold. Up to now, the effect of this scaffold has not yet been confirmed in animal models, although how to prepare this scaffold has been reported.

THE ALTERATION OF AFP mRNA CONCENTRATION IN PERIPHERAL BLOOD WITH HEPATOCELLULAR CARCINOMA DURING TRANSHEPATIC ARTERAL CHEMOTHERAPY AND EMBOLIZATION / 解放军医学杂志

To find the rule of alterations in AFP mRNA concentration in peripheral blood in patients with hepatocellular carcinoma(HCC) before and after the treatment with transhepatic arterial chemotherapy and embolization(TAE), 15 cases of the pateints with HCC were included in this survey. The AFP mRNA concentration in peripheral blood of the patients were investigated using compatitive RT PCR technique before and 1,2,3,4, 5,6,7, 14, 28 days after TAE. The results showed that AFP mRNA concentration on the third day after TAE was the highest. It declined to the level before treatment during one week.It suggested that AFP mRNA concentration changed with a rule, and following the rule, preventive measure to distant metastasis could be instituted in clinical work.
