120 casea of bronchogenic carcinoma treated 286 times by BAI revealed several types of bronchial arterial variations in 12 cases and multiple feeding arteries in 56 cases by way of selective Bronchial arteriography.The article emphasizes the significance of the existence bronchial arterial anomalies and multiple feeding arteries in BAI.And also we ex plored the selective catheterization technique in the bronchial arteriography.

0.05) when all cases were put together. But the observed morbidity in group B (20%) was less than that in group A (40%) with the difference being statistically significant (?~2=4.41,P=0.036). ConclusionsThe POSSUM methodology allows satisfactory prediction of mortality and morbidity rates in patients undergoing colorectal tumor surgery.

Objective To introduce the preliminary experience of using rigid neuroendoscope in repair of spinal meningocele or myelomeningocele. Methods 3 infantile patients aging between 13 months and 22 months underwent the resection and repair of spinal meningocele or myelomeningocele in May, 2013. The operations were performed under the direct visualization of the rigid neuroendoscope in the aid of the intraoperative electrophysiological monitoring. All the surgical manipulations were accomplished outside the sheath of the endoscope. Results The surgical procedures were smooth. All the patients recovered satisfactorily. There was no postoperative complication. At the one-year follow-up, they were developing normally. Conclusions The rigid neuroendoscope is useful to the resection and repair of spinal meningocele and myelomeningocele. It could simplify the surgical procedures.

Objective:Some antigens of M.tb to culture with peripheral blood mononuclear cells ( PBMC) for assaying their proliferation and activation,so as to signify whether lipid antigens of M.tb have specific immune responses in host against M.tb infection or not.Methods:We treated PBMC with several lipid antigens of M.tb to explore the ability of these antigens to activate immunity in healthy individuals.We measured and analyzed cell proliferation by labeling cells with carboxyfluorescein succinimidyl amino ester (CFSE) and subjecting them to flow cytometry (FCM).The production of IFN-γ,TNF-αand IL-4 by T cell subsets (NKT,CD4+, CD8+,andγδT) from healthy donors was analyzed by FCM after stimulation with autologous immature dendritic cells pre-cultured with M.tb lipid antigens.The tested M.tb lipid antigens were the total lipid (TLIP),Acetone-Soluble Lipids (ASLIP),Purified Sulfolipid (PSLIP),Lipoarabinomannan (LAM) and Lipomannan (LM) levels.Medium free of lipid antigens(WCL,CFP,LPS,Mtb-HAg and blank) was used as a control.Results:We found the proportion of proliferative NKT and CD8+T cells significantly increased in all lipid groups (P<0.05).ASLIP,LAM and LM promoted non-proliferative CD4+T cells to secrete IL-4 and proliferative ones to secrete IFN-γ( P<0.05).All lipid antigens promoted both proliferativeγδT cells and CD8+T cells to secrete IFN-γand TNF-α,but the proportion of TNF-α-secreting cells in these populations decreased in the LM group ( P<0.05 ).Conclusion: Lipid antigens may affect the CD1-restricted T cells of the host to fight M.tb infection.

Objective To analyze the pitfalls of 18F fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET-CT) scan in the diagnosis of 60 patients of tuberculosis mimicking malignancy.Methods The study included 60 patients with PET-CT diagnosis of probable malignancy.Fifty patients were proved to be tuberculosis by pathological examinations and 10 were diagnosed by clinical followup.The images of whole body were acquired at 60 min after administration of 222-555 MBq 18F-FDG.The PET-CT imaging characteristics and clinical data,including lesion size,distribution,standardized uptake value (SUV) were retrospectively analyzed.After the whole body scan of PET-CT,each patient had a chest spiral CT scan for detailed observation of lung lesions.Contrast enhanced CT (CECT) was performed in 8 patients.Results (1)Thirty patients were misdiagnosed as lung cancer,14 patients as malignant lymphoma,6 patients as malignant mesothelioma,3 as intestine carcinoma,2 as bone malignancy,1 patient as hepatocarcinoma,spleen malignancy,ovarian cancer,laryngocarcinoma and nasopharyngeal carcinoma respectively.(2) 90.9％ (20/22) of patients showed normal level of serum CEA and 100％ (13/13) of patients showed normal level of CA199.Increasing serum CA125 was found in all patients (6/6) with activeTB patients accompanied with ascites,pleural fluid and (or) pericardial effusion.(3) 93.3％ (28/30)active tuberculosis showed accumulated 18F-FDG which was incorrectly interpreted as malignancy.The most common sites of TB lymphadenopathy were bilateral cervical tissues,which was accounted for 85.7％(12/14).CECT revealed characteristics of peripheral enhancement and central necrosis in tubercular lymphadenopathy,which was 87.5％ (7/8).Conclusions The diverse manifestations of TB on imaging and high uptake of 18F-FDG on PET imaging result in misdiagnosis of malignancy.It is important for radiologists and nuclear medicine physicians to identify the common imaging features and patterns of TB to make a correct diagnosis.Integration of reconstruction HR CT,PET-CT and lab examinations may improve the diagnostic accuracy.
