Among them, 200 clients who underwent physical examination from August to October 2021 were selected as the control group to implement routine physical examination mode, another 200 clients who underwent physical examination from August to October 2022 were selected as the experimental group to implement the "4M1E" comprehensive management mode. The ultrasonic examination time, passing rate, bladder filling, pre-examination knowledge score and satisfaction of the two groups were compared.Results:The ultrasonic examination time of experimental group was (9.54 ± 3.25) min, lower than (12.33 ± 5.07) min of control group, and the difference was statistically significant ( t=6.53, P<0.05). The passing rates of ultrasonic examination at 1 time, 2 times and 3 times in the experimental group were 86.0% (172/200), 12.0% (24/200) and 2.0% (4/200), respectively, which were better than 73.5% (147/200), 20.5% (41/200) and 6.0% (12/200) in the control group with statistical significance ( χ2=10.05, P<0.05); the proportions of overfilling, proper filling and poor filling in the experimental group were 1.0% (2/200), 86.0% (172/200) and 13.0% (26/200), respectively, which were better than 2.0% (4/200), 70.0% (140/200) and 28.0% (56/200) in the control group, the differences of two groups were statistically significant ( χ2=14.93, P<0.05). Pre-examination knowledge score of experimental group (8.16 ± 1.43) was higher than that of control group (6.19 ± 1.94) points, and the difference was statistically significant ( t=-11.48, P<0.05). The overall satisfaction score of the experimental group (20.55 ± 2.46) was higher than that of the control group (18.45 ± 2.86). The differences was statistically significant ( t=-7.87, P<0.05). Conclusions:The "4M1E" comprehensive management mode can make physical examination clients fully prepare for the examination, reduce the time of ultrasonic examination, complete the examination efficiently, and comprehensively improve the sense of experience and satisfaction.

Construction of recombinant adenovirus expressing capsid protein of serotype O foot-and-mouth disease virus and analysis of its immunogenicity / 生物工程学报

In order to construct a recombinant replication deficient human type 5 adenovirus (Ad5) expressing a foot-and-mouth disease virus (FMDV) capsid protein, specific primers for P12A and 3B3C genes of FMDV-OZK93 were synthesized. The P12A and 3B3C genes were then amplified and connected by fusion PCR, and a recombinant shuttle plasmid pDC316-mCMV-EGFP-P12A3B3C expressing the FMDV-OZK93 capsid protein precursor P12A and 3B3C protease were obtained by inserting the P12A3B3C gene into the pDC316-mCMV-EGFP plasmid. The recombinant adenovirus rAdv-P12A3B3C-OZK93 was subsequently packaged, characterized and amplified using AdMaxTM adenovirus packaging system, and the expression was verified by infecting human embryonic kidney cell HEK-293. The humoral and cellular immunity levels of well-expressed and purified recombinant adenovirus immunized mice were evaluated. The results showed that rAdv-P12A3B3C-OZK93 could be stably passaged and the maximum virus titer reached 1×109.1 TCID50/mL. Western blotting and indirect immunofluorescence showed that rAdv-P12A3B3C-OZK93 expressed the FMDV-specific proteins P12A and VP1 in HEK-293 cells. In addition, the PK cell infection experiment confirmed that rAdv-P12A3B3C-OZK93 could infect porcine cells, which is essential for vaccination in pigs. Comparing with the inactivated vaccine group, the recombinant adenovirus could induce higher FMDV-specific IgG antibodies, γ-IFN and IL-10. This indicates that the recombinant adenovirus has good immunity for animal, which is very important for the subsequent development of foot-and-mouth disease vaccine.
