Objective:To detect the expression of microRNA-218 (miR-218) in human acute lymphocyte leukemia (ALL) T lymphocytes ( CCRF-CEM) ,explore its effects on the biological features of CCRF-CEM cells and the expression of its target gene c-kit, so as to provide new insights for leukemia treatment.Methods: Using the quantitative real-time polymerase chain reaction ( qRT-PCR) ,we detected the expression of miR-218 in the normal peripheral blood T lymphocytes and CCRF-CEM cells.Forty-eight hours after the miR-218 mimic was transfected into the CCRF-CEM cells,the expression of miR-218 in the CCRF-CEM cells was detected by qRT-PCR.The effect of miR-218 on the CCRF-CEM cell viability was detected using MTT.The effect of miR-218 on the proliferation and apoptosis of CCRF-CEM cell was analyzed using flow cytometry.c-kit gene was identified to be a target gene of miR-218 by luciferase reporter enzyme system,and the effect of miR-218 on the expression of KIT protein in cells were determined using Western blot.Results:As shown by qRT-PCR,compared with that in the normal peripheral blood T lymphocytes,the expressions of miR-218 in ALL T lymphocytes cell lines were significantly decreased ( P<0.01 ) .Compared with the control group, the expression of miR-218 increase significantly in CCRF-CEM cells transfected with miR-218 mimic for 48 hours ( P<0.01).MTT showed that the cell viability decreased significantly after the over-expression of miR-218 in the CCRF-CEM cells ( P<0.05 ) .Flow cytometry showed that the S-phase fraction significantly declined after the over-expression of miR-218 ( P<0.01 ) , and meanwhile the apoptosis of cells also significantly increased (P<0.01).Luciferase reporter gene assay showed that,compared with the control group,the relative luciferase activity significantly declined in the miR-218 mimic transfection group (P<0.01).Compared with the control group,the expression of KIT protein in the CCRF-CEM cells transfected with miR-218 mimic for 48 hours significantly decreased ( P<0.01).Conclusion:The expression of miR-218 decreases in ALL T lymphocytes cell lines.MiR-218 can negatively regulate the expression of KIT protein,inhibit the proliferation and increase the apoptosis of CCRF-CEM cells.Treatment based on the enhanced expression of miR-218 may be a promising strategy for leukemia.

Objective To establish a scientific and sensitive evaluation index system of nursing quality for cancer hospital. Methods The evaluation index system of nursing quality for cancer hospital was formulated based on literature,semi- structured interviews and expert group discussion. Then, developing the evaluation index system of nursing quality for cancer hospital by two rounds of Delphi consultation. Results The experts′ authority coefficient was 0.862.

The Kendall coordination coefficients of the importance of the three level indicators were 0.354,0.217,and 0.243, The Kendall coordination coefficients of the feasibility of the three level indicators were 0.234,0.313,and 0.339. Conclusions Scientific nature and concentration indicator system of nursing quality for cancer hospital was developed. It will be used to provide quantitative basis for the control of nursing quality in cancer hospital.

Objective: To investigate the efficacy and safety of using pegylated recombinant human granulocyte-colonystimulating factor (PEG-rhG-CSF) in preventing neutropenia in multiple chemotherapy cycles. Methods: A multicenter, prospective, open-label, singlearmstudy was designed. Patients with malignant tumors, such as lung, ovarian, and colorectal cancers, who received multiple cycles of chemotherapy with the prophylactic use of PEG-rhG-CSF for 2-4 consecutive cycles participated in the study. Results: After the prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 4.76% (13/273) in the first cycle to 1.83% (5/273), 1.15% (2/174), and 2.08% (2/96) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 11.36% (31/ 273) in the first cycle to 6.23% (17/273), 2.87% (5/174), and 3.13% (3/96) in subsequent cycles. The incidence of febrile neutropenia (FN) during the first cycle was 0.73% (2/273). The duration of FN was 2 days in one case and 5 days in another case. FN was not observed during the second, third, or fourth cycle. After the secondary prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 25% (7/28) to 3.57% (1/28), 0% (0/28), and 6.67% (1/15) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 71.43% (20/28) to 10.71% (3/28), 14.29% (4/28), and 0% (0/15) in subsequent cycles. The proportion of patients who received antibiotic therapy during the entire chemotherapy period was 10.48% (44/420). Conclusion: The application of PEG-rhG-CSF once per chemotherapy cycle can effectively reduce the occurrence of neutropenia in patients under multiple cycles of chemotherapy treatment with good safety.
