Objective To construct human single-chain antibody gene library associated with lung adenocarcinoma, and screen lung adenocarcinoma cell A549-specific antibody. Methods The lymphatic tissue near lung adenocarcinoma was used to construct human single-chain antibody gene library. The specific antibody to lung adenocarcinoma cell A549 was screened from the antibody library. Positive clone bacteria were transformed to E. coli HB2151, and their dissolvability was observed. The soluble scFv was purified by affinity chromatography and its relative molecular mass was determined by SDS-PAGE and Western blotting. The specificity of scFv to human lung adenocarcinoma cells was identified with ELISA. Results The phage antibody library of 4.6?107 was constructed successfully. Single-chain antibody of human lung adenocarcinoma was enriched. The ratio of yield was increased gradually, 181 times higher after 5 rounds of panning than after the first round of panning. SDS-PAGE and Western blotting results showed soluble scFv' molecular mass was about 30 000. ELISA showed dissolved antibody had high specificity to bind A549 cells, not MDA-MB-435. Conclusion The single-chain antibody gene library of human lung adenocarcinoma was constructed successfully, and specific antibodies to lung adenocarcinoma were screened, providing the basis for single-chain antibody radionuclide imaging and treatment.

BACKGROUND: Intramyocardial transplantation of autologous umbilical cord-derived mesenchymal stem cells for repair of myocardial tissue damage is paid increasing attention in the cardiovascular field. OBJECTIVE: Human umbilical cord mesenchymal stem cells were isolated and cultured. Passage 2 human umbilical cord mesenchymal stem cells were treated with various concentratins of 5-azacytidine (2.5, 5, 10, 20, 40, 80 μmol/L) for 24 hours . After removal of 5-azacytidine, cells were cultured for another 4 weeks. RESULTS AND CONCLUSION: Before 5-azacytidine treatment, filament-like structures or particles were not observed in the cells, but the amount of cytoplasm was less and uniform, nuclear/cytoplasm ratio was high, cells exhibited typical fusiform appearance and grew in a swirl-like manner, and nucleolus was obvious. After treatment with 5-azacytidine for 24 hours, some cells died in each group, and typical fusiform appearance turned into stick-like or column-like appearance, especial y in the 40 and 80 μmol/L 5-azacytidine groups. Reverse transcription-PCR results showed that atrial natriuretic peptide and α-skeletal actin gene expression levels were detected on human umbilical cord mesenchymal stem cells after treatment with 2.5 or 40 μmol/L 5-azacytidine for 4 weeks or with 5, 10, 20 μmol/L 5-azacytidine for 1, 2, 3 and 4 weeks. These findings suggest that 5-azacytidine-induced human umbilical cord mesenchymal stem cells express the specific gene of myocardiocytes.

Objective To evaluate the effect of nursing interventions on the quality of life of patients undergoing continuous ambulatory peritoneal dialysis (CAPD).Methods Randomized controlled trials (RCTs) involving nursing interventions were collected from the databases of Cochrane,PubMed,Elsevier Science Direct,VIP,CNKI and WanFang.Data were analyzed with RevMan 5.1 software.Results 8 articles met the inclusion criteria.The results of Meta-analysis showed that there was considerable heterogeneity across the analysis,which might be resulted from length of intervention and patients of different ages according to subgroup analysis,and that gender was not the factor causing heterogeneity.In the experimental group,both physical and emotional aspects after receiving nursing interventions were significantly improved than the control group.Conclusions Nursing interventions can improve the quality of life of patients with CAPD.
