Objective To explore the moves that creating magnetic work environment in hospital, in order to improve the nurses job satisfaction and reduce the turnover rate then stable the nursing team. Methods Through a series of measures such as the establishment of scientific rational allocation of human resources, implementing fair performance evaluation and allocation mechanism, carrying out the nurse grading management system to create magnetic nursing work environment, the nurse job satisfaction and turnover rate were compared before and after the measures. Results In January 2014 a total of 520 questionnaireswere issued, 519 valid questionnaires, and the effective recovery rate was 99.81%(519/520);And 559 were valid of 577 issued questionnaires, which was 96.88% (559/577). The overall score of nurses′job satisfaction increased from (3.20±0.46) points in 2013 to (3.41±0.52) points in 2014 (t=9.40, P= 0.000); The nurse turnover rate fell to 1.97%(13/661) from 5.13% (30/585) (χ2= 10.27, P= 0.003). Conclusions That is very important for remain stable and high quality nursing team to carry out scientific and fine management according to the demand of nurses, so as to create a safe, harmonious, positive, cooperative magnetic nursing work environment which have development direction and space.

The practice of general practice emphasizes that the general practitioner is the backbone, and the primary health institution is the main body, which solves the main health problems of the commu-nity and meets the basic health service needs of the residents. Rehabilitation medicine occupies a prominent position in the community health service, and its related knowledge and skills are the important part of the whole medical education. However, rehabilitation medicine has more teaching contents, less training time and out-of-date teaching model, which have made the effect of rehabilitation medicine teaching not good. In the rehabilitation medicine teaching for training general practitioners, by strengthening the concept of reha-bilitation, elaborating teaching content, optimizing teaching ward-round, and outstanding ability as well as reforming evaluation way, we try to exercise the students' clinical thinking and improve clinical skills, to cultivate outstanding qualified general medical practitioners for community rehabilitation ultimately.

Objective:To explore the effect of case-based learning (CBL) guided by ICF (International Classification of Functioning, Disability and Health) in rehabilitation practice teaching.Methods:Fifty-eight rehabilitation undergraduates who had practiced in the Department of Rehabilitation Medicine in The First Affiliated Hospital of Chongqing Medical University from February 2019 to December 2019 were randomized into observation group and control group. The observation group adopted ICF-guided CBL method for practice teaching, while the control group adopted traditional teaching methods. At the end of the internship, all the students were assessed in terms of their theoretical knowledge, case analysis and clinical practice ability. At the same time, questionnaires were used to conduct a satisfaction survey on the teaching method, and the results of the two groups were compared and analyzed by ttest and rank-sum test through SPSS 25.0. Results:The scores of the observation group were higher than those of the control group, with statistical significance ( P<0.05) . In the satisfaction survey, the observation group was superior to the traditional teaching method in terms of self-thinking ability and learning initiative, with statistical significance ( P<0.05). Conclusion:ICF-guided CBL method can strengthen students' independent thinking ability and learning initiative, and improve the students' clinical comprehensive ability of rehabilitation treatment.

Background and purpose:Adenosine triphosphate-binding cassette superfamily G member 2 (ABCG2), which has been found over-expressed in a variety of cancer cells, takes part in the drug resistance of cancer through effux of anticancer drugs. The purpose of this study was to investigate the mechanisms of human glioblastoma cells sensitivity to pyropheophorbide-a methyl ester (MPPa)-mediated photodynamic therapy (PDT) eradicating tumour cells and its relationship to ABCG2.Methods:U87 and A172 glioma cell lines in the logarithmic growth phase were selected and exposed to the treatment of MPPa-PDT and MPPa-PDT+fumitremorgin C (FTC) respectively. The cell viability was measured with the use of CCK-8 assay. The expression of ABCG2 was detected by Western blot. The intracellular contents of MPPa in each group without illumination were tested by lfow cytometry. Flow cytometry with AnnexinⅤ-FITC/PI double staining was used to detect the cell apoptotic rate. DCFH-DA staining was used to assess the generation of intracellular reactive oxygen species (ROS).Results:The MPPa-mediated PDT could eradicate A172 and U87 cancer cells in an energy-dependent manner. The light energy density in A172 was 8 times of that in U87 when the cell viability reached median lethal dose after MPPa-mediated PDT. The high expression of ABCG2 in A172 cells affected the accumulation of intracellular MPPa. Inhibition of ABCG2, not only could enhance the eradicating effect of MPPa-PDT on A172 cells, but also could increase the yield of ROS triggered by MPPa-PDT and the accumulation of intracellular MPPa.Conclusion:The human glioblastoma cell line A172 is insensitive to MPPa-mediated PDT. The mechanism may relate to ABCG2, which decreases the MPPa content in cancer cells through effux of MPPa, resulting in decline of cytotoxicity.

Objective:To explore the effect of a new teaching mode, which includes bridge-in, outcome, pre-test, participation, post-test and summary (BOPPPS), on the online teaching of radiobiology related knowledge for cancer radiotherapy practitioners.Methods:Taking the cell survival curve, cell cycle and radiosensitivity as examples, the radiotherapy practitioners in multiple university-affiliated hospitals were organized to carry out a multicenter prospective randomized control study. All practitioners were randomly divided into BOPPPS group and control group. The courses for BOPPPS group were designed as an online classroom, consisting of pre-class preparation, online teaching and post-class stages. The online teaching stage included video viewing, basic knowledge learning, literature discussion, group discussion and others. The control group employed the traditional teaching mode. The χ2 test was used to compare the consistency of general conditions between the two groups, and nonparametric test was used to compare the differences in scores between two or more groups. Results:The score of the pre-class test was 58.56 ± 0.99. Post-class average score for BOPPPS group was 85.48±0.85 and for control group 77.79±1.10, with the former being higher 7.69 ( Z=5.31, P<0.001) than the latter. The average answer time was (296.62±15.40) s for BOPPPS group and (386.41±21.27) s for control group, with the former being shorter 89.79 s ( Z=3.34, P=0.001) than latter. Subgroup analysis shown that the scores of BOPPPS group were significantly rising, regardless of whether or not the students had studied radiobiology courses. Among the students who have not studied these courses, the scores were rising greatly. Moreover, From the analysis of different positions, it was found that both the scores of BOPPPS group and control group have risen, especially for doctors, deputy chief doctors, physicists and technicians. There were also statistically differences between different degrees, with significantly rise in scores for undergraduate and doctoral students ( Z=3.64, 4.18, P<0.001). Conclusions:The flexible application of BOPPPS teaching mode to the online education of such boring disciplines, like radiobiology, is of great significance to raise the theoretical basis of radiotherapy practitioners.

Objective:To investigate the clinicopathological features, treatment programs and prognosis of patients with primary diffuse large B-cell lymphoma (DLBCL) in cavernous sinus.Methods:The clinical data of a patient with primary DLBCL in cavernous sinus who were admitted to Wuhan No.1 Hospital in December 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 63-year-old female who underwent resection of the cavernous sinus lesion, and the pathological diagnosis was DLBCL. The patient received 6 courses of R-CHOP regimen chemotherapy, lumbar puncture + intrathecal injection of chemotherapy drugs, and twice additional rituximab immunochemotherapy, and no tumor cells were found in the results of liquid-based thin layer cytology for cerebrospinal fluid exfoliated cells; twice magnetic resonance imaging (MRI) re-examination after the operation showed no recurrence and adjacent metastasis of the tumor. The patient's symptoms were significantly improved without residual neurological sequelae.Conclusions:Primary DLBCL in cavernous sinus is rare in clinical practice, early diagnosis is crucial for the prognosis of patients, and different protein expression may indicate the prognosis. Biopsy, complete resection of the tumor under the premise of preserving important anatomical structures and functions, and standardized chemotherapy combined with intrathecal injection local chemotherapy can effectively prolong the survival time of patients and improve the quality of life.
