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.

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.

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 investigate the predicting value of serial serum human stromelysin-2 (ST2)testing on prognosis in elderly patients with acute heart failure(AHF).Methods 75 AHF patients aged 60 to 90 were selected in our study who were in Beijing Hospital during 2013.1 ～ 2014.8,blood sampling of serum ST2 took place at admission and 72-96 h later.Moreover,38 healthy people aged 70 to 80 were chosen as control group.Follow-up was performed 1 year after acute attack.We defined the end of observation as recurrence of heart failure or any cause of death.The data was analyzed by SPSS19.0.Results Among 55 AHF patients,sST2 level was higher in patients with endpoint events than those without it on the two moment(P=0.000).And we found that the change in sST2 was higher in patients with endpoint events than those without it(P=0.023);and the percentage change in sST2 was also significantly different(P=0.033).Receiver operator curve analysis of the change in sST2 from baseline to 72-96 h later was strongly reflective of prognosis with area under the curve(AUC) of 0.696(P=0.013).And the change in sST2 Combined with the sST2 level at admission to predict the prognosis of AHF,the result would be more exciting,the area under the receiver operating characteristic (ROC) curve is 0.861 (P ＜ 0.001).The endpoint event rate of the patients whose level of sST2 at admission was below 1408 ng/L and the change level in sST2 below 101 ng/L was 21.4％(3/14),while the data in patients whose level of sST2 at admission is above 1 408 ng/L and the change level in sST2 above 100 ng/L was 85.7％(12/14).Conclusions in elderly patients of AHF,sST2 elevate markedly.The result shows that the level of sST2 may be used to evaluate AHF prognosis.And the change in sST2 are able to predict the prognosis of AHF.Compared with NT-proBNP,serial sST2 testing appears to be a promising candidate for monitoring these patients.
