ABSTRACT
Objective:To investigate the current situation of clinical help-seeking of anesthesiologists and analyze the influencing factors of help-seeking behaviors in order to provide a basis for improving the help-seeking ability of anesthesiologists.Methods:The anesthesiologists in 35 public hospitals in Hubei province were investigated using a self-designed questionnaire, and the demographic differences and influencing factors related to help-seeking were analyzed.Results:The score for the help-seeking attitude questionnaire of anesthesiologists was (3.6±0.4). The score for the help-seeking needs sub-questionnaire of anesthesiologists was (2.7±0.6), and the score for the help-seeking behavior sub-questionnaire was (3.0±0.4). The item with the highest score was " special patients or patient emergency needs help", and the item with the lowest score was " self injury potential needs help". There was a statistically significant difference in the scores for the help-seeking needs sub-questionnaire for anesthesiologists of different ages and working years ( P<0.05), and there was no statistically significant difference in the scores for the help-seeking attitude questionnaire and help-seeking behavior sub-questionnaire for anesthesiologists of different genders, ages, professional titles, working years, personnel types, and whether they obtained a doctor′s license ( P>0.05). The percentage of anesthesiologists who believed that " they did not ask for help timely or without asking for help" was 35.4%, and the percentage of anesthesiologists who believed that " colleagues did not ask for help timely or without asking for help" was 50.7%. Among the reasons why the need for help did not translate into help-seeking behavior, the percentage of anesthesiologists who believed that " doctors think they can solve" was the highest (74.0%). Conclusions:Anesthesiologists in public hospitals have a positive attitude towards seeking-help and can better translate the need for help into behaviors. The main reasons for delay in seeking-help or non-seeking-help are inaccurate assessment of their own ability and inability to grasp the opportunity of seeking-help, and targeted training should be carried out to improve the doctors′ help-seeking ability.
ABSTRACT
We constructed recombinant adenoviruses expressing miR-29b2c (Ad-miR29b2c), and analyzed their effects on the proliferation and migration of HGC-27 and MGC-803 cells. miR-29b2c gene was amplified by PCR from genomic DNA and cloned into the pAdTrack-CMV vector to create the shuttle plasmid pAdT-29b2c. The recombinant plasmid was verified by restriction enzyme digestion and sequencing. The linearized shuttle vector was mixed with an adenoviral backbone plasmid (pAdEasy-1), followed by cotransformation into competent BJ5183 cells to generate the recombinant plasmid pAd-miR-29b2c. Finally, recombinant adenoviral vectors were generated by transfecting the recombinant plasmid into 293A packaging cell line. HGC-27 and MGC-803 cells were infected with the recombinant adenoviruses expressing pAd-miR-29b2c, then MTT and wound-healing assay were used to analyze the effects of pAd-miR-29b2c on the proliferation and migration of HGC-27 and MGC-803 cells. The miR-29b and miR-29c levels were significantly increased in HGC-27 cells after infected with pAd-miR-29b2c. MTT and wound-healing analysis also revealed a significant decrease in proliferation and migration of HGC-27 and MGC-803 cells compared to the control Ad-GFP-infected cells. Furthermore, western blotting results demonstrated that the protein expression level of δ-catenin was reduced in pAd-miR-29b2c transfected HGC-27 and MGC-803 cells. Taken together, the recombinant adenoviral vector was generated, and it can significantly inhibit the proliferation and migration of HGC-27 and MGC-803 cells.
