Objective To build an evaluation index system of medical practitioners'competency for county-level public hospitals. Methods By means of the Iceberg Model based on competence and professionalism, and following two rounds of consultations of 47 experts, the evaluation indexes and weights of medical practitioners' competency were determined using SPSS frequency, mean, Kendall harmony coefficient and factor analysis. Three county-level public hospitals in Shaanxi province were selected for example verification of service competency. Results The evaluation index system of county-level public hospitals included 4 level-1 indexes and 16 level-2 indexes. The 4 level-1 indexes were diagnosis competency, treatment competency, communication competency and self-development competency. The weights of these indexes were 0.3,0.3,0.2 and 0.2 respectively. Conclusions Such hospitals should start with these competencies to strengthen the cultivation of medical practitioners' competency and constantly improve their comprehensive service level.

Objective:To survey the working status of outpatient nurses in general practice departments of general hospitals.Methods:From March to April 2021, personal in-depth interviews were conducted with outpatient nurses from general practice residency training bases in Beijing. The thematic framework analysis method was used to analyze the interview data and refine the themes.Results:Fourteen nurses working in general practice outpatient clinics were interviewed in this study. Four themes were extracted from the interview data: (1) inadequate staffing of full-time outpatient nurses in general practice departments of comprehensive hospitals; (2) unclear job functions for outpatient nurses in general practice departments; (3) no standardized patient health education in the department; (4) no relevant training received systematically.Conclusion:General practice departments in general hospitals should setup full-time general practice nurse positions, clarify the job responsibilities, strengthen the relevant training and enhance core competency for nurses working in general practice department.

Objective: To investigate the overexpression frequencies of BRE and EVI1, the correlation between BRE and EVI1 expressions and their possible clinical implications in 11q23/MLL rearrangement acute leukemia. Methods: Cytogenetic examination of bone marrow cells was performed by short-term culture method. R-banding technique was used for karyotype analysis. 47 patients were detected by interphase fluorescence in situ hybridization (FISH) with dual-color break apart MLL probe. The expressions of EVI1 and BRE genes were detected by real time quantitative reverse transcription polymerase chain reaction (RQ-PCR) . The correlation and prognostic significance were statistically tested. Results: 11q23/MLL rearrangements were confirmed by karyotyping and FISH, respectively in 47 patients. According to immunophenotypic analyses of 37 patients, 5 patients showed positive for CD19, CD79a or CD10, 1 for CD7; the others for CD33, CD13, CD14 and CD15, and 16 of them for CD34. Of the 47 patients, 18 patients showed EVI1 overexpression and most of them presented with t (6;11) and M₄/M₅. The EVI1 expression was high in t (6;11) or t (9;11) subgroup comparable with levels observed in normal subgroup (P=0.038, 0.022, respectively) . 15 patients showed high BRE expression, and most of them presented with t (9;11) and M₄/M₅. High BRE expression was found in t (4;11) , t (6;11) , t (9;11) and t (11;19) subgroups, respectively by comparing with normal subgroup. The BRE expression was higher in t (4;11) (P=0.004) or t (9;11) (P=0.012) subgroup than in t (6;11) subgroup. Patients with EVI1 overexpression had a short survival compared with those with low EVI1 expression (P=0.049) and it also did in t (9;11) subgroup (P=0.024) . Patients with t (9;11) and high BRE expression had a long survival compared with those with t (9;11) and low BRE expression (P=0.024) . Conclusion The EVI1 overexpression was significantly frequent in acute leukemia patients with 11q23/MLL rearranged, especially within t (6;11) subgroup and M₄/M₅, which was associated with an inferior outcome. High BRE expression was observed frequently in 11q23/MLL-rearranged acute leukemia especially within t (9;11) subgroup and M₅.

OBJECTIVETo report clinical and laboratory features of 4 cases of myeloid neoplasm with t (5;12) (q33;p13).

METHODSCytogenetic examination of bone marrow cells obtained from patients was performed by 24 h culture method. R banding technical was used for karyotype analysis. PDGFRβ gene rearrangement was detected by FISH using dual color break apart PDGFRβ probe. ETV6-PDGFRβ fusion genes were detected by multiple-reverse transcription polymerase chain reaction (RT-PCR). Direct sequencing analysis was performed on the PCR products in case 1. Immunophenotype analysis was carried out by flow cytometry. Four cases were treated with imatinib (IM) and followed up.

RESULTSThe diagnoses included 3 MPN and 1 AML-M2. The t (5;12) (q33;p13) was a primary abnormality in 3 cases of MPN and a secondary abnormality in 1 case of AML-M2. PDGFRβ gene rearrangement and ETV6-PDGFRβ fusion genes were detected by FISH and multiple-RT-PCR in 4 cases, respectively. The immunophenotypical analysis of leukemia cells showed positive for CD13, CD33 and CD34. Two cases obtained MMR after the treatment of IM, one case complete hematologic and complete cytogenetic response. ETV6-PDGFRβ was negative detected by multiple-RT-PCR after the treatment of IM, but relapsed and died soon in case 4.

CONCLUSIONSThe t (5;12) myeloid neoplasm was a subtype with unique features. The t (5;12) maybe a primary chromosome abnormality in MPN and a secondary in AML. MPN with t (5;12) could benefit from IM, but not for AML. Dual-FISH was a reliable tool for detecting PDGFRβ rearrangement.
