Objective To investigate the immune response of IL-10 to Schistosoma japonicum infection in the early infectioin model and SEA immunization model of the IGTP~(-/-) and IRG-47~(-/-) mice.Methods In the early infection model,the IGTP knock out (IGTP~(-/-)) mice,IRG-47 knock out (IRG-47~(-/-)) mice and wild-type (WT) C57BL/6J mice were exposed to 300 S.japonicum cercariae via the pinna and sacrificed on day 7 post-infection.Each mouse pinna section was stained with hematoxylin-eosin (HE) to detect the pathological lesions,and the culture supernatant of pinna was used to test the levels of Th1/Th2 cytokines by indirect ELISA.In the SEA immunization model,IGTP~(-/-) IRG-47~(-/-) and WT mice were immunized with SEA twice and sacrificed in 3 weeks after the initial immunization.SEA-specific IgG antibody in sera was detected by indirect ELISA;the levels of Th1/Th2 cytokines were tested in culture supernatant of splenocytes by indirect ELISA;the proportions of CD4~+ T cells,CD8~+ T cells,B cells,Th1 and Th2 cells in the spleen were assayed by FACS.Results Although no obvious differences on the pathology of pinna were observed among the three mouse groups,the level of IL-10 in the culture supernatant of pinna of IRG-47~(-/-) mice was lower than that of IGTP~(-/-) mice in 7 days after the exposure.Following SEA immunization,the level of SEA-specific IgG antibody in sera of IGTP~(-/-) mice was lower than that in WT mice,the level of IL-10 in the culture supernatant of splenocytes of IRG-47~(-/-) mice was higher than that of IGTP~(-/-) and WT mice with the stimulation of SEA.However,the proportion of Th2 cells in the spleen of IRG47~(-/-) mice was the lowest among the three mouse groups.Conclusions SEA is the stimulus of IRG-47 deficiency mice to defend Schistosoma japanicum infection and promote the host to produce a protective response,and IL-10 may play an important role in immune regulation in this process.

Background and objective The aim of this study is to assess the effect of video-assisted thoracoscopic surgery (VATS) and video-assisted mini-thoracotomy (VAMT) in the treatment of non-small cell lung cancer (NSCLC). Methods We searched PubMed, EMbase, CNKI, VIP and ISI Web of Science to collect randomized controlled trials (RCTs) of VATS versus VAMT for NSCLC. Each database was searched from May 2006 to May 2016. Two reviewers independently assessed the quality of the included studies and extracted relevant data, using RevMan 5.3 meta-analysis software. Results We finally identified 13 RCTs involving 1,605 patients. There were 815 patients in the VATS group and 790 patients in the VAMT group. The results of meta-analysis were as follows: statistically significant difference was found in the harvested lymph nodes (SMD=-0.48, 95%CI: -0.80--0.17), operating time (SMD=13.56, 95%CI: 4.96-22.16), operation bleeding volume (SMD=-33.68, 95%CI: -45.70--21.66), chest tube placement time (SMD=-1.05, 95%CI: -1.48--0.62), chest tube drainage flow (SMD=-83.69, 95%CI: -143.33--24.05), postoperative pain scores (SMD=-1.68, 95%CI: -1.98--1.38) and postoperative hospital stay (SMD=-2.27, 95%CI: -3.23--1.31). No statistically significant difference was found in postoperative complica-tions (SMD=0.83, 95%CI: 0.54-1.29) and postoperative mortality (SMD=0.95, 95%CI: 0.55-1.63) between videoassisted thoracoscopic surgery lobectomy and video-assisted mini-thoracotomy lobectomy in the treatment of NSCLC. Conclusion Compared with video-assisted mini-thoracotomy lobectomy in the treatment of non-small cell lung cancer, the amount of postoperative complications and postoperative mortality were almost the same in video-assisted thoracoscopic lobectomy, but the amount of harvested lymph nodes, operating time, blood loss, chest tube drainage flow, and postoperative hospital stay were different. VATS is safe and effective in the treatment of NSCLC.
