Selective COX-2 inhibitors can promote the apoptosis of tumor cells and block the growth of new blood vessels through the inhibition of ring oxidase,vascular endothelial growth factor,microvessel and so on. Research shows that COX-2 is overexpressed in vascular and endothelial cells of lung cancer,select COX-2 inhibitors to adjuvant chemotherapy,not only can directly inhibit the tumor proliferation,but also can reduce the adverse reaction of chemotherapy drugs,and enhance the curative effect. To investigate the effects of selec-tive COX-2 inhibitors and cisplatin in lung cancer angiogenesis and its mechanism,will be a hope for the clini-cal treatment of tumor.

Objective To know the situation of nurses obtaining osteoporotic fractures related knowledge ,and provid guiding basis for further education and relevant training on target people .Methods Questionnaire survey and semi -structured interviews methods were used to investigate 595 nurses ,9 clinical nurse workers and nurse managers who come from a tertiary comprehensive teaching hospital were interviewed personally .Results The scores of the related knowledge in nurses were 35 .70 ± 6 .36 ,score rate was 67 .36% ;Interview data analysis showed that lack of professional training ,training was not systematic ,the approach obtain knowledge was simple were result in lack of the related knowledge in nurses ;By the multiple liner stepwise regression ,The educa‐tion level and professional title were main factors which affect nurses acquired osteoporosis knowledge .Conclusion It is necessary to focus on improving the strengthen of related knowledge education for the nurses with low education background and low profes‐sional title ,At the same time ,related departments of the hospital should strengthen the training of professional knowledge .

Objective To observe the effectiveness of the percutaneous transluminal angioplasty (PTA) and percutaneous transluminal stenting (PTS) for central vein occlusion in maintenance hemodialysis patients.Methods From January 2010 to August 2015,a total of 42 patients with center vein occlusion of arteriovenous fistula were treated with maintenance hemodialysis,and the surgery and postoperative conditions,revascularization and improvement of vascular stenosis were observed.Results Among the 42 patients,38 cases were successfully carried out with PTA,and the patency rate was 90.5%(38/42).A total of 32 intravascular stents were placed in 30 patients whose vein stenosis were still greater than 30% after PTA.After surgery,the swelling of the patient receded rapidly and the internal fistula went back to normal.Conclusion PTA and PTS are effective methods for maintenance hemodialysis patients with central vein occlusion,and they could help protecting functional access in patients with autogenous fistulas with smaller wounds and faster effects.

Background To construct and analyze the differentially expressed gene library in the SD rat's brain of Parkinson's disease.Methods The lateralization Parkinson's disease model of SD rat was established by stereotaxis injection of 6-OHDA in lateralization corpora striatum. Suppression subtractive hybridization was utilized to isolate the cDNA fragments in both control and experimental groups. Then the cDNA fragments were directly bound to pMD18-T to set up the subtractive library. Amplification of the library was carried out by transformation of E. coli with high voltage electroperforation. Ninety five positive bacteria clones were randomly picked up and identified by colony PCR.Results The amplified library contained more than 1500 positive bacteria clones. Ninety-five clones were analyzed randomly by colony PCR. And there were 81% clones contained 100 ～600 bp DNA fragments. They might be the cDNA fragments of differentially expressed genes of Parkinson's disease.Conclusions A differentially expressed genes subtracted cDNA library of Parkinson's disease of SD rat was constructed successfully with SSH and T/A cloning techniques. The library is efficient and it was useful in screening and cloning new and specific differential expression genes of Parkinson's disease.

0.4,P0.05)with HHS.[Conclusion]The result of this study suggest that HHS can not capture additional important quality of life domains except for physical function and pain relief that are influenced by THA.So it's necessary to combine HHS and a quality of life survey such as SF-36 to allow a more global assessment of THA.
