Objective:To select human chronic myeloid leukemia (CML) cell line K562 as the experimental object, and use lentivirus mediated CRISPR/Cas9 gene editing technology to construct a stable CML cell line K562/TCRP1-KO that knocks out the tongue cancer resistance related protein 1 (TCRP1) gene; and through functional tests such as cell proliferation, apoptosis, and drug sensitivity, compare the phenotypic differences between K562/TCRP1-KO and control cells (K562/cas9-CTL), and preliminarily explore the possible mechanism of TCRP1 gene involvement in the pathogenesis of CML.Methods:The small guide RNA (sgRNA) targeting TCRP1 was designed at a specific location. After annealing, the oligonucleotide fragments were recombined with the linearized Cas9 expression vector, and the lentivirus packaging system was transfected into 293T cells. The purified virus was collected and infected with K562 cells. Positive polyclons were screened for puromycin pressure, and monoclonal K562/TCRP1-KO was further screened by limited dilution method. Stable cell lines were successfully knocked out by sanger sequencing and Western blot detection; Simultaneously, K562 cells transfected with lentiCRISPR vector were constructed as control cell lines (K562/cas9-CTL); Using cell counting method, cell counting kit 8 (CCK8) method, imatinib (IM) gradient dilution method, and flow cytometry cell proliferation, drug sensitivity, and apoptosis analysis were performed on K562/TCRP1-KO and K562/cas9-CTL, respectively.Results:The sgRNA-Cas9 recombinant plasmid vector for TCRP1 knockout was successfully constructed, and after transfection into 293T cells, TCRP1 knockout monoclonal cell lines were successfully screened using limited dilution method. Compared with K562/cas9-CTL cells, the proliferation ability of K562/TCRP1-KO cells was significantly reduced, IM drug sensitivity was significantly enhanced, and the process of cell apoptosis was significantly accelerated (all P<0.05). Conclusions:A CML cell line with TCRP1 knockout was successfully constructed using CRISPR/Cas9. TCRP1 may act as a cancer related gene to affect the proliferation, IM resistance, and apoptosis process of CML cells.

ObjectiveTo describe the differences in imported malaria cases before and after the COVID-19 pandemic in Pudong New Area, Shanghai, to explore the possible impact of isolation measures during the pandemic on malaria, and to provide a basis for formulation of malaria control strategies during the prevention and control of major infectious diseases in the future. MethodsInformation on malaria cases reported in Pudong New Area from 2017 to 2022 was collected and divided into two groups: cases before the COVID-19 pandemic (2017‒2019) and cases after the COVID-19 pandemic (2020‒2022). Analysis was conducted on information such as gender, age, parasite species, country of infection, place of onset, time of onset, time of first diagnosis, time of confirmed diagnosis, hospitalization, and duration of treatment for both groups. ResultsThe pre-COVID group consisted of 21 cases, and post-COVID group consisted of 28 cases, with male and falciparum malaria predominating in both groups. There were statistically significant differences between the two groups in terms of Shanghai residency status, use of preventive measures, and adherence to standardized treatment (P<0.05). The time interval from symptom onset to first diagnosis was longer in the pre-COVID group than that in the post-COVID group (Z=-2.617, P<0.05 ). The interval from the first diagnosis to the confirmed diagnosis and duration of treatment were shorter in the pre-COVID group than that in the post-COVID group (Z=-3.381, P<0.05; Z=-4.148, P<0.05). There was no significant difference in gender, age, malaria classification, source of infection, onset area, length of hospital stay, complications, severe cases, and interval between onset and diagnosis between the two groups (P>0.05). ConclusionAfter the outbreak of COVID-19, the medical priority plan prolongs the treatment time of malaria patients, increasing the risk of severe illness and death.
