To develop a quality control checklist for the prevention and control of coronavirus disease 2019 (COVID-19) in fever clinic and isolation ward of the general hospital and to assess its application. Based on the relevant prevention and control plans and technical guidelines for COVID-19,Delphi method was used to identity items for evaluation,and a quality control checklist for the prevention and control of COVID-19 in the fever clinic and isolation ward was developed in Sir Run Run Shaw Hospital. The checklists included 8 dimensions and 32 items for fever clinic,7 dimensions and 27 items for the isolation ward. The appointed inspectors conducted daily quality control for each shift with this checklist. The expert authority coefficient was 0.88,the mean of the importance of each index in the quality control table was not less than 4.8,and the coefficient of variation was not more than 0.07. During the entire February 2020,8 problems were found and rectified on-the-spot with the application of the checklist. Quality inspection rate was 100% in both isolation wards and fever clinic. The compliance rate and accuracy rate of hand hygiene were 100%; the correct rate of wearing and removing protective equipment increased from 96% to 100%. During the same period,a total of 1915 patients were admitted to the fever clinic,including 191 suspected patients (all were isolated in the hospital,3 were confirmed). There were no medical staff infected with COVID-19,no cross infection of patients and their families in the hospital. A quality control checklist for the prevention and control of COVID-19 has been developed and applied in the isolation wards and fever clinic,which plays an important role in preventing nosocomial infection.

Objective To investigate the effect and mechanism of HPV16-E7 gene specific CRISPR/Cas (clustered regularly interspaced short palindromic repeat/CRISPR associated system) on the cell apoptosis and proliferation of human cervical cancer SiHa cell line.Methods HPV16 positive cervical cancer SiHa cells and HPV16 negative human embryonic kidney HEK293 cells were cultured and each of the cells were divided into 3 groups respectively in the experiment:the control group was untreated,the C9 group was transfected only with Cas9 plasmid,and the Cri group was cotransfected with guide RNA (gRNA) plasmid and Cas9 plasmid (1∶3).T-7endonuclease Ⅰ assay was used to detect double strand break (DSB) formation in SiHa cells.The apoptosis rates of SiHa and HEK293 cells were detected by flow cytometry (FCM).CCK-8 was used to evaluate the proliferation of SiHa and HEK293 cells.Western blotting was applied to detect E7 and pRb protein expression.Results The SiHa cells in Cri group showed DSB formation at 48 h after transfection.The apoptosis rate of Cri group at 48 h was 26.6%,higher than 2.6% in control group (x2 =5.455,P =0.020) and 3.1% in C9 group (x2 =6.279,P =0.012).The apoptosis rates of control,C9 and Cri group were 7.4%,7.6%,7.9% for HEK293 cells respectively.Compared with the control and C9 group,the apoptosis rate of the Crigroup showed no statistical significance (x2 =0.032,P =0.858;x2 =0.034,P =0.853).After 72 h transfection,the inhibition rate of SiHa cells in Cri group was 29.4%,higher than 15.0% in control group (x2 =22.481,P =0.000) and 18.0% in C9 group (x2 =24.879,P =0.000).The inhibition rate of the HEK293 cells in Cri group was 3.2%,and it showed no significant difference compared with the inhibition rate of C9 group (2.2%,x2 =2.857,P =0.091) and control group (2.3%,x2 =3.438,P =0.064) respectively.Down-regulated expression of E7 protein and up-regulated expression of pRb protein were detected of the SiHa cells in Cri group compared with the control group,while the E7 protein and pRb protein level did not show difference in the C9 group.Conclusion CRISPR specifically targeting HPV16-E7 oncogene can promote apoptosis of SiHa cells,and inhibit the cell proliferation.It is speculated that CRISPR system may induce DSB event of E7 gene,and result into increased expression of tumor suppressor protein pRb.

Enthusiasm is an intrinsic motive that drives the ethical and moral aspects of nursing practice.Love is the source of enthusiasm.An enthusiastic nurse loves life,work and patients.Loving patients is essential to inflame passion for patient care.A desire for and pursuits of benevolence is the key to enthusiasm.Only the element of benevolence integrated into enthusiasm can nurses arouse a sense of compassion,responsibility and honour,which is then advanced to the realm of humanitarian-Heal the Wounded,Rescue the Dying.The essence of enthusiasm is sincerity,that is,providing patients wholehearted care rather than hypocritical act.Caring for patients is based on goodwill and altruism.Enthusiasm is also the driving force for nurses' creativity.It inspires a positive life,pushes to pursue self-actualization and propels continuous creation.
