ABSTRACT
Objectives Objectives To investigate how the imbalance of innate lymphoid cells (ILCs)in the peripheral blood of patients with lung adenocarcinoma affects the balance of downstream mononuclear macrophages and T helper (Th) cells, and to identify the impact of the imbalance of ILCs on the immune status and prognosis of lung adenocarcinoma. Methods The peripheral blood of 20 patients with lung adenocarcinoma and normal controls were collected. The percentage of ILCs, mononuclear macrophages and T lymphocyte in peripheral blood were analyzed by flow cytometry. The characteristic cytokine secretion levels of various types of immune cells in peripheral blood were detected by real-time fluorescence quantitative PCR. Results Compared with the normal controls, the proportion of M2 mononuclear macrophages, ILC1 and ILC2 in patients with lung adenocarcinoma was up-regulated, while the proportion of M1 mononuclear macrophages, CD4+ T and CD8+ T was down-regulated. The mRNA expression of related cytokines of M1 mononuclear macrophages and ILC1 were decreased; while the mRNA expression of related cytokines of M2 mononuclear macrophages and ILC2 were increased. Along with the decreased CD4+T cells-associated cytokine T-bet mRNA expression, and the increased GATA3 mRNA expression. Moreover, the expression of PD-1 in CD8+ T cells was also up-regulated. Conclusion The imbalance of ILCs in peripheral blood of patients with lung adenocarcinoma promotes the imbalance of mononuclear macrophages and Th cells, which altogether maintains the immunosuppression in patients with lung adenocarcinoma, and promotes the development of lung adenocarcinoma.

Objective To compare of the clinical using effect of implantable venous -access port(VAP) among different methods and the postoperative complication.Methods From 2011 to 2014,a total of 359 patients with VAP were included in this study.All patients were divided into two groups according to the surgery approaches methods,307 cases were implanted through internal jugular vein,and other 52 cases were through subclavian vein intubation.Statistics of postoperative flow conditions and complication between the two groups were gathered and com-pared.Results There were 3 cases of postoperative infected,and 13 cases were not free of transfusion,while 2 cases catheter were shed and shifted in the 307 cases of implantation through internal jugular vein,the complication rate was 5.86%;In other group,which in total of 52 cases of implantation through subclavian vein,including 2 cases were post-operative infected,6 cases were not free of transfusion,2 cases are of catheter fracture and5 cases were local hemato-ma,the complication rate was 28.85%.There was difference in rate of catheter leakage,catheter tip dystopy and cath-eter related infection between two groups[the proportion of through internal jugular vein vs that the group through sub-clavian vein:5.86%(18 /307)vs 28.85%(15 /52),χ2 =28.140,P =0.000].Conclusion The study suggests that the two ways of different operation methods of VAP are safe and reliable for long term intermittent venous access.The internal jugular vein implanted group has a slight advantage over the group of subclavian vein implanted,when it comes to develop the patients′living quality.
