0.05).There was significant difference in the 3-year survival rate between A and C group. Conclusions The 3-year survival rate was dramatically increased with combined therapy mainly by cisplatin, the dose of 60～80mg is tolerant for the elderly aged above seventy years, and perioperation complications can be cured.

Objective To study the complications related to and its management after retrieving temporary and retrievable IVC filters.Methods From Jul 2007 to Mar 2012,576 consecutive cases of deep venous thrombosis secondary to bone fractures confirmed by Duplex ultrasonography,received IVCF deployment to avoid fatal pulmonary embolism during perioperative period.There were 192 cases receiving temporary filters and 384 cases with retrievable filters.The temporary and retrievable filters were removed 2 to 4 weeks after implantation.Results The success rate of temporary filter removing was 100％.In 24 cases,the filters captured huge thrombi,and they were removed after thrombolysis using the Uni-fuse catheter.One patient received permanent filter deployment before removing the tempo-filter.Filters were successfully removed in 367 out of 384 cases with retrievable ones with a successful rate of 95.57％.In 7 cases the filters were removed with large thrombi.Double-snare-technique was used to retrieve 15 seriously tilted filters.After a mean 22 months follow-up,no pulmonary embolism occurred,but symptomatic DVT were revealed in 26 patients,and the conditions were improved after anticoagulation treatment.Conclusions The application of Uni-fuse thrombolysis catheter increases the success rate of filters retrieving,double-snare-technique helps retrieve seriously tilted filters and decrease long-term complications of permanent filters.

Objective To compare the sub-cellular proteome of isoniazid ( INH)-resistant Mycobacterium tuberculosis (MTB) with that of sensitive strains for identifying of unique proteins of these strains and discussing their preliminary application in clinical diagnosis. MethodsProteins of cell wall and membrane of 5 INH-resistant strains and 5 INH-sensitive strains were extracted by density gradient centrifugation.The extracts were subsequently analyzed using weak cation exchange (WCX) liquid chromatography ( LC )followed reverse phase (RP) liquid chromatography to compare the sub-cellular protein patterns. A total of 1280 fractions were collected and identified by matrix assisted laser desorption ionization-time of flight-tandem mass spectrometry (MALDI-TOF MS/MS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for cell component and biological process analysis. Normalized Spectral Abundance Factors (NASF) was used for semi-quantity of protein expression. 5 proteins significantly up-regulated in INH-resistant strains and 2 proteins significantly up-regulated in INH-sensitive strains were selected for ELISA analysis with autologous sera respectively. Results A total of 347 proteins were identified. Cell component analysis showed that 58％ proteins were cells well or membrane proteins. Biological process analysis showed that 31％ proteins involved in carboxylic/monocarboxylic acid biosynthetic and metabolic process, 26％ and 15％ proteins involved in organic acid or fatty acid biosynthetic and metabolic process,while 28％ proteins involved in lipid biosynthetic , metabolic, transport and localization process. O-succinylbenzoate synthase, monooxygenase, hypothetical protein Rv2255c, nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase and membrane phosphatidate cytidylyltransferase cdsA were up-regulated in INH-resistant strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-sensitive sera. The differences between the INH-resistant sera and the INH-sensitive sera were significant ( t = 0.028, 0.044, 0.066, 0.064, 0.083, all P＜0.01 ). Chain A of Rv2002 Gene Product and Chain A of Crystal Structure Of Rv2632c were up-regulated in INH-sensitive strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-resistant sera. The differences between the INH-sensitive sera and the INH-resistant sera were significant (t=0.053, 0.073, both P＜0.05). ConclusionThe combination of density gradient centrifugation and 2D-LC MS/MS technology is useful in enrichment and identification of differential expressed proteins between INH-resistant and INH-sensitive strains at sub-cellular level. It is useful in finding antigens associated with INH-resistant MTB infection, which may prove useful for further study in the mechanism of INH resistant, as well as interaction between MTB and host.

OBJECTIVE To provide the clinical anatomy data of the lingual artery for clinical application concerning about the lingual artery. METHODS CTA examination of the carotid artery was performed in 80 adult volunteers. The 3D reconstruction images of the carotid artery with hyoid bone were obtained by using 64-slices spiral CT. At the same time, 20 extraoral dissections of the submandibular region were performed on 10 human cadavers. The origin, pathway, and anatomic relations of the lingual artery in CTA and cadavers were studied. The distance from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were separately measured, and the distance between the segment of the greater horn of hyoid bone of lingual artery and the middle of greater horn of hyoid bone were also measured. And the contrast analysis was carried on the result. RESULTS The lingual artery was mainly come from the external carotid artery (74.4 % in the CTA; 80% in the Cadavers), the next origin was come from the facial artery (23.1 % in the CTA; 20 % in the Cadavers), and it was few to found that the lingual artery had origin in the superior thyroid artery, which was 2.5 % in CTA and none in Cadavers. The path of the lingual artery had high variation, but the position between the segment of the greater horn of hyoid bone of lingual artery and the greater horn of hyoid bone had constancy relatively. The lingual artery run forward with approximation parallel to the greater horn of hyoid bone into tongue,and which located in thesuperior to the greater horn of hyoid bone (2.32?1.29 mm) or in the inferior to the greater horn of hyoid bone (2.00?1.68 mm). The distances from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone in CTA and cadavers were (12.93?7.36) mm, (10.40?5.75) mmand (14.80?6.18) mm, (8.35?5.44) mm respectively. CONCLUSION The lingual artery can be show clearly in CTA and can get the anatomy data in physiological condition with CTA.
