Objective:To explore the incidence and factors of the influence of preoperative related factors on postoperative orthopedic evaluation, through the evaluation of thoracic shape orthopedic evaluation of children pectus excavatum, during plate implantation after Nuss procedure.Methods:From April 2012 to April 2019, the clinical data were analyzed retrospectively for 159 hospitalized cases of Nuss procedure for pectus excavatum in Xi’an Children’s Hospital.The mean age was(6.8±3.4) years old(3.2-17.0 years old); males 124, females 35; Haller index 4.0±1.0(2.7-7.5); 6 cases(4%) were poor orthopedic evaluation with the thoracic shape, males 5, femal 1; 23 cases (14%) were average satisfied with the thoracic shape, males 16, femals 7; 130 cases (82%)were good orthopedic evaluation with the thoracic, males 103, femals 27. Follow-ups were conducted for at least 2 years, Retrospective analysis of the relationship between postoperative thoracic satisfaction and age, gender, Haller index, how the plates were placed during surgery and symmetry of funnel chest, t test and χ2 test were used for statistical analysis. Results:There were statistically significant differences between thoracic orthopedic evaluation after postoperative and classification of pectus excavatum ( P=0.001), and poor orthopedic evaluation after asymmetric pectus excavatum operationand ; There were no significant differences in gender, Haller index, surgical method and how the plates were placed during surgery( P>0.05). However, it can be seen from the mean and percentage that with the decrease of age, and the increase of Haller index, the orthopedic evaluation gradually becomes worse. Conclusion:According to our single-center study, asymmetric pectus excavatum is a factor for poor orthopedic evaluation during plate implantation after Nuss, especially for young children and children with larger Haller index.

Chemotherapy is one of the most important methods of cancer treatment.However,multidrug resistance (MDR) has been the main factors affecting their efficacies.Recent studies show that the amplification of MDR1 gene in tumor cells,the over expression of the related drug resistance protein and the cell cycle and apoptosis pathway in signal transduction are the main causes for the failure of chemotherapy.

Objective To investigate the expression of hypoxia inducible factor-1?(HIF-1?) and heparanase(HPA),and their relationship during hypoxia in human ovarian cancer cell line SKOV3.Methods SKOV3 cells were incubated in different groups,immucytochemistry was applied to qualitatively assay HPA protein,Western-blot was used to detect the protein expression of HIF-1? and HPA,and mRNA expression was determined by RT-PCR.Results The positive expression of HPA localized in cytoplasma.Western-blot analysis revealed that the protein expression of HIF-1? was significantly increased(P
