Objective To constructe ,package and identificate the lentiviral vector with overexpression gene Grp78 .Methods We used lentiviral vector and genetic engineering technology to obtain the aim gene fragment and to constructe recombinant plas‐mid .we prepared competent cells and transform the cells .Through positive clone sequencing ,lentivirus was packaged and virus titer was tested .Results Positive cloning sequence comparison results show that the test was passed .Melt curve did not appear mixed peak ,also did not appear abnormal peak broadening .It means that does not appear pollution ,primer dimers and nonspecific amplifi‐cation in the experiments .Conclusion The construction ,packaging and identification of lentiviral vector with over expression gene Grp78 are sucessful .

Objective: To understand the status quo and differences of the rights and interests of primary medical staff in a community, and to provide targeted suggestions for improving the rights of such staff. Methods: From October to November 2018, a questionnaire survey was conducted on all the medical staff of 8 community health service centers in a district of Shanghai, and 562 valid samples were obtained. Results: The primary medical staff had the highest demands for " pay rise" (4.783±0.598), " paid vacation" (4.569±0.873)and " additional reserve fund" (4.553±0.963); the lowest demands were placed on " education-based promotion" (3.797±1.382), " refresher training" (3.801±1.314), and " opinion feedback mechanism" (4.018±1.223). At the same time, the rights and interests of these staff in different occupational categories were significantly different(P<0.05)in " daily reimbursement" , " housing subsidy" , " refresher training" and " opinion feedback mechanism" . Conclusions The salary demands of the primary medical staff are the most obvious, and there are differences in the demands of medical staff in different occupational categories. It is suggested to establish a more reasonable salary system and pay attention to the differentiated appeals of different medical personnel.
