RESUMO
Objective To systemic evaluate postoperative pulmonary function between segmentectomy and lobectomy in patients with early stage non-small cell lung cancer.Methods Computer searched was performed up to September 2016 at the Cochrane Library,PubMed,EMBASE,CBM,CNKI,VIP and Wanfang database,collected postoperative pulmonary function between segmentectomy and lobectomy in Patients with early stage Non-Small Cell Lung Cancer.Study selection,data collection and critical assessment of the included studies were performed according to the recommendations of the Cochrane Collaboration.Results Eight studies included 308 segmentectomy and 386 lobectomy were identified for inclusion.FVC％ (MD =9.91,95％ CI:3.53-16.30,P =0.002),postoperation / preoperation FVC％ (MD =6.74,95％ CI:5.52-7.79,P ＜0.05),FEV1％ (MD =13.25,95％ CI:10.25-16.26,P ＜ 0.05),postoperation / preoperation FEV1％ (MD =7.18,95 ％ CI:5.88-8.48,P ＜ 0.05) showed significant difference.Conclusion Pulmonary function index was superior to lobectomy after segmentectomy in patients with early stage lung cancer,and segmentectomy resection was more beneficial to preserve lung function.

RESUMO
Objective:To analyze a novel epitope of Homo sapiens synapse associated protein and synthesize polyclonal antibody.Methods:FRG4 full-length sequence was obtained by PCR from human fetal liver library;by bioinformatics to detect the second structure of amino acids encoded by FRG4 and its epitope and motifs;by solid-phase peptide synthesis method to synthesize FRG4 peptides,then peptides were immunized to rabbits;by immunohistory to detect the expression of FRG4 in HepG_2 cells.Results:Select 13-peptides PKLVKEEVFWRNY by bioinformatics to synthesize rabbit anti-human FRG4 polyclonal antibody.Antibody purity was 82.79% and antibody dilution was 1∶16 000 detected by ELISA.The antibody had a good reaction and speciality in Western blot,it was mainly expressed in cytoplasm of HepG_2 cells.Conclusion:A novel Homo sapiens synapse associated protein(FRG4) antibody was synthesized successfully.
