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.

Cell-free DNA, also referred to as extracellular DNA, has been detected in many kinds of human body fluids, including blood plasma, urine, cerebrospinal fluid, bronchoalveolar lavage fluid, amniotic fluid, and seminal plasma. At present, cell-free DNA has been reported widely as promising noninvasive biomarkers for disease diagnosis and research. Recent years have witnessed some progress in the studies of the general characteristics of cell-free DNA, such as its concentration, extent of molecular weight, origin and existing forms, as well as in its clinical application. Cell-free seminal DNA has been proposed as promising noninvasive biomarkers for the studies and diagnosis of male idiopathic infertility, and the early diagnosis, treatment evaluation and outcome prediction of testicular germ cell tumors and prostatic cancer. This review summarizes the general characteristics and biological functions of cell-free DNA, and outlines the research status and application perspective of cell-free seminal DNA.

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.
