Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

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： The authors used the serial analysis of gene expression (SAGE) method to analyze transcripts present in the immortalized BEP2D cells and the malignant transformed BEP2D cells. Methods： As a step toward understanding the complex gene expression differences between the immortalized BEP2D cells and the malignant transformed BEP2D cells induced by α  particle,SAGE method was introduced into this experiment. Technological methods included total RNA extraction, mRNA isolation, full length of dscDNA synthesis, PCR, transformation and sequencing. SAGE SoftWare was used to analyze tag sequences and compare the abundance of tags between two SAGE libraries. Results： Two independent SAGE libraries were constructed from the immortalized BEP2D cells and the malignant transformed BEP2D cells induced by 1.5 Gy α  particles. A total of 2 331 SAGE tags were identified for the sequences, representing 252 unique transcripts. Though up to now the obtained information is limited, comparison of the two SAGE libraries indicated a remarkable similarity in the expression profiles. Of the 252 transcripts detected, 12 transcripts (4.8％ ) matched no reliable known genes in UniGene library. Combination of Northern blot hybridization, the expression level of TGF β induced Smad7 gene in the malignant transformed cells was higher than that in the immortalized cells. Conversely, Chemokine receptor CCR11 gene was expressed at lower levels in the malignant transformation cells. Conclusion： (1) Out of results given by SAGE,the tendency of the abundance of gene expression and the gene expression differentiation between two cell lines were described. (2) The expression level of TGF β induced Smad7 gene in the malignant transformed BEP2D cells was higher than that in the immortalized cells and chemokine receptor CCR11 gene was expressed at lower levels in the malignant transformed BEP2D cells. (3)SAGE was a powerful method in a quantitative and simultaneous analysis of a large number of transcripts in any particular cell system, especially in defining functions of known genes.

OBJECTIVETo study the efficacy and safety of multimodal prevention of postoperative venous thromboembolism for hip fractures.

METHODSFrom March 2009 to July 2011, preoperatively, patients were assigned to two groups on the basis of an assessment of their risk factors. One hundred and twelve patients were considered to be low risk, involving 47 males and 65 females,with an average age of (72.40 +/- 13.29) years ranging from 42 to 88,and were managed with aspirin (100 mg once daily for 14 days) as well as intermittent gasing compression devices. Twenty-six patients were considered to be high risk, involving 12 males and 14 females with an average age of (78.50 +/- 12.76) years ranging from 65 to 84,and were managed with low-molecular-weight heparin (0.4 ml,subcutaneous injection once daily for 14 days) and intermittent gasing compression. All patients were underwent Doppler ultrasonography within 24 hours before hospital discharge. All patients were followed-up for 3 months postoperatively. The incidence of deep venous thrombosis of lower limb, pulmonary embolism, gastrointestinal hemorrhage were recorded.

RESULTSOverall, there were no fatal pulmonary embolism, 1 case of symptomatic pulmonary emboli in low risk group, and none were detected in the high-risk group. Deep venous thrombosis was detected in association with 6 (6.25%) of the 112 procedures in the low-risk group and 2 (7.69%) of the 26 operations in the high-risk group. Paitents were selected in opened reduction and internal fixation, the quantity of bleeding, decrease of hemoglobin, hematoma rate, and gastrointestinal hemorrhage rate of low risk group were (538.10 +/- 390.20) ml, (30 +/- 19) g/L, 0, and 1 (1.03%) respectively; those of the high-risk group were (585.95 +/- 403.96) mL, (32 +/- 20) g/L,1 (4.76%), (4.76%), there were no significant different between the two groups, all P > 0.05.

CONCLUSIONThere were no statistic significances between the aspirin as well as intermittent gasing compression devices and the low-molecular-weight heparin and intermittent gasing compression in preventing venous thromboembolism (VTE) in postoperative postoperative venous thromboembolism for hip fractures. However, there are potential advantages to reduce complications of bleeding and cardiovascular disease. Multimodal prevention of postoperative venous thromboembolism can protect postoperative patients with hip fractures.
