Objective To investigate the expression of SOX4 and C/EBPα mRNA in chronic myeloid leukemia (CML) and their clinical significances. Methods Bone marrow samples from 68 cases of CML including 57 newly diagnosed patients and 11 patients treated with imatinib were collected, and peripheral blood mononuclear cells from 30 healthy people were collected as healthy control. The expression of SOX4 and C/EBPαmRNA and protein levels were detected by RT-PCR and Western blot, respectively. The relations between the expression of SOX4 and C/EBPα and the influences of imatinib on SOX4 and C/EBPα were analyzed. Results The expression level of SOX4 mRNA was increased in newly diagnosed CML patients compared with that of normal control group (6.545 5±1.495 2 vs. 0.059 6±0.018 8, t=3.139, P=0.002 3), but the expression level of C/EBPαmRNA was significantly decreased (0.238 8±0.033 8 vs. 0.810 5±0.056 2, t=9.240, P<0.000 1). The expression levels of SOX4 and C/EBPαmRNA had no significant correlation with age, gender, white blood cell count (WBC) and bcr-abl of newly diagnosed patients (all P>0.05). The expression level of SOX4 mRNA in 5 patients treated with imatinib was decreased (0.120 6 ±0.044 9 vs. 0.557 9±0.144 8, t=2.885, P=0.020 4), and the expression level of C/EBPαmRNA was increased (0.330 3±0.042 4 vs. 0.150 5±0.046 5, t=2.855, P=0.021 3). The expression level of SOX4 mRNA in 6 patients who developed blast phase during the treatment of imatinib was increased (0.469 9±0.123 0 vs. 0.050 2±0.036 6, t=2.370, P=0.039 3), and the expression level of C/EBPα mRNA was decreased (0.197 9 ±0.064 7 vs. 0.378 7±0.042 9, t=2.327, P=0.042 3). The expression of SOX4 mRNA was negatively correlated with C/EBPα mRNA (t=-0.554 6, P=0.002 8). Conclusions In newly diagnosed CML, the expression level of SOX4 is increased, C/EBPα is decreased compared with that of healthy control, and both have negative correlation. In the patients in blast phase after imatinib treatment, SOX4 gene is up-regulated, and C/EBPα is down-regulated. C/EBPα-SOX4 axis may play a role in the occurrence and development of CML. SOX4 may be a new molecular target for the treatment of CML.

Objective To investigate the etiology spectrum of hand , foot and mouth disease ( HFMD) and to analysis the molecular characteristics of three predominant human enterovirus stains in Qingdao in 2013.Methods The total enterovirus (EV) strains and strains of EV71, CVA16 and CVA6 in throat swabs of HFMD cases were detected by using multiplex real time RT-PCR.The full-length of the viral VP1 genes of the EV strains were amplified and sequenced .The sequences were phylogenetically analyzed by using the MEGA5.0 software package .Results A total of 841 patients with mild HFMD and 107 patients with serious HFMD were recruited in this study and 64 .3%of them were positive for EV .The predominant pathogens were EV71 (44.8%), CVA6 (28.2%) and CVA16 (9.5%) in 2013.CVA6 replaced CVA16 as the second most common pathogen for HFMD , accounting for 42.7% of all pathogens in children aged less than 3 years and 22.2%of all pathogens in the serious patients .The proportions of CVA6 in the etiology spectrum showed a downtrend along with the increasing age of the patients (P<0.001).Phylogenetic analy-sis of the complete VP1 gene sequences showed that all of the EV 71 strains identified in this study belonged to the subgenotype C4 (evolutionary branch C4a) and all of the CVA16 strains belonged to the subgenotype B1 (evolutionary branches B1a and B1b).There were 6 genogroups (A to F) regarding to the VP1 gene of CVA6 and all of the CVA6 strains identified in this study belonged to genogroups A and D .Among the CVA6 strains isolated in Qingdao in 2013, 83.9% belonged to genogroup A, while the rest 16.1% belonged to genogroup D.66.7%of the CVA6 strains isolated in 2012 belonged to genogroup A, while the rest 33.3%belonged to genogroup D .All of the CVA6 strains isolated from year 2008 to 2011 in Qingdao belonged to genogroup D.Conclusion EV71, CVA6 and CVA16 were the prevalent pathogens responsible for the de-velopment of HFMD in Qingdao in 2013.The proportions of CVA6 strains in the etiology spectrum showed a downtrend with the increasing age in children .C4a was the major subtype of EV71 strains circulating in Qingdao in 2013, while B1a and B1b were the major subtypes of CVA16 strains.The pattern of endemic cir-culation of CVA6 strains showed a trend of changing from genogroup D to A from year 2008 to 2013 .

Objective To investigate health literacy before and after the medical intervention and its influencing factors so as to provide evidence for public health promotion.Methods Stratified multi-stage random sampling method was applied for residents aged 15-69 years from 8 urban or rural communities of Taishun County of Lucheng District.The comprehensive health literacy promotion and intervention was carried out,and a unified citizen health literacy questionnaire was designed.Residents' health literacy,the three aspects of health literature and five categories of health literacy issues levels were compared before and after the intervention,and Chi-square test was used for data analysis.Results The overall rate of having health literacy was 11.8％ and 16.3％ in 2012 and 2013,respectively (x2=7.20,P＜ 0.01).The rate of basic health concept and knowledge,health lifestyles and behaviors,and medical skills were significantly raised from 18.5％,9.4％ and 23.5％ to 28.0％,14.6％ and 33.5％,respectively (x2 values were 21.60,11.07 and 20.85,respectively; all P＜0.01).As to the five issues of health literacy,the level of the scientific healthy literacy,the chronic disease literacy,the literacy of infectious disease,the safety and first aid literacy and the basic health literacy were significantly inclined (52.4％ vs.40.4％,39.3％ vs.31.8％,27.8％ vs.22.4％,74.0 ％ vs.58.2％ and 41.9％ vs.33.8％,respectively; x2 values were 27.79,34.95,8.10,43.07 and 13.61,respectively; all P＜0.01).Conclusion Health education was helpful in the promotion of healthy literacy.Healthy lifestyles and behavior literacy and chronic disease prevention literacy should be important for the rural,elderly,low-education level and low-income populations.

Objective To observe the effect of brain-derived microvesicles (BDMVs) on cytoskeleton in human umbilical vein endothelial cells (HUVECs).Methods BDMVs were prepared in vitro and identified by transmission electron microscopy and particle size identification.HUVECs were co-cultured with PKH26-1abeled BDMVs for 0.5,1,and 2 h;flow cytometry was used to detect the phagocytosis of HUVECs for BDMVs at different time points.HUVECs cultured in vitro were divided into control group,BDMVs treatment group and nimodipine treatment group;cells in the BDMVs treatment group were given 1.5× 107/mL BDMVs;cells in the nimodipine treatment group were pretreated with 2 μg nimodipine (0.2 mg/mL) for 10 min,and then,given 1.5×107/mL BDMVs.After being stained with rhodamine-labeled phalloidin,the fluorescence intensity and number of stress fibers of fibroactin in HUVECs were observed by laser confocal microscopy.Results BDMVs had complete membrane structure with a diameter of 100-1000 nm under transmission electron microscopy.The proportion of cells phagocytizing BDMVs increased significantly with prolonged incubation time,enjoying significant differences (0.5h:22.7％±1.2％;1 h:52.3％±1.3％;2h:71.6％±1.9％,P＜0.05).Laser confocal microscopy showed that,as compared with the control group,the fluorescence intensity ofcytoskeletal protein was obviously increased and the number of stress fibers increased was obviously larger in the BDMVs treatment group.As compared with those in the BDMVs treatment group,the fluorescence intensity of cytoskeletal protein was decreased and the number of stress fibers was obviously smaller in the nimodipine group.Conclusion The role of BDMVs in phagocytosis of HUVECs becomes stronger as time being prolonged,and BDMVs phagocytosis leads to cytoskeletal remodeling,which can be partially blocked by nimodipine.

Objective:To understand the current situation of male nurses in Dalian area and explore its future development direction.Methods:From August to September in 2020, 189 male nurses who had been engaged in clinical nursing for more than one year in 29 hospitals in Dalian were selected by convenient sampling method, and they were investigated by questionnaire. SPSS 25.0 software was used for statistical analysis. The counting data were described by rate or constituent ratio. Logistic regression analysis was used to analyze the important factors influencing male nurses′ willingness to change profession.Results:A total of 189 male nurses were investigated, 137 of them were under 30 years old, accounting for 72.5%. They had high education background and low professional title, mainly concentrated in ICU, operation room and emergency department of public owned 3A or 3B hospitals, with a monthly income of 3 000 to 8 000 yuan. 33 nurses(17.5%) chose nursing profession because they couldn′t change careers by profession adjustment. 135 nurses (71.4%) considered that work pressure was high. 70 nurses (37.0%) had the idea of changing careers. The main influencing factors included:nursing career was not in accordance with individual interest, dislike of female boss, low income. The prominent problem in nursing career was "inconvenience in gender""the confusion of self-positioning".Conclusions:The hospital should improve the income of male nurses, reduce the work pressure, establish magnetic hospital, establish career planning for them, and expand the team of male nurses. Male nurses should take the initiative to improve their professional ability and professional title, so as to provide necessary conditions for the realization of nursing managers, educators, researchers and other professional goals.

Objective To establish the measurement of IgA1 O-glycan-specific antiglycan autoantibodies in patients with IgA nephropathy (IgAN),and evaluate their role in the development and progression of IgAN.Methods In the IgAN regular follow-up cohort of Peking University Institute of Nephrology from January 2006 to December 2015,170 patients drawn by stratified randomization were enrolled in this study.Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of plasma galactose-deficient IgA1 (Gd-IgA1) and antiglycan autoantibody (IgG and IgA1).The correlation between antiglycan autoantibodies and clinicopathological parameters was analyzed by linear correlation and multiple linear regression analysis.The receiver operating characteristic curve (ROC) was used to evaluate the value of plasma anti glycide antibodies in the diagnosis of IgAN.Results IgG and IgA1 antiglycan antoantibodies that specifically recognized Fab-hinge region (Fab-HR) antigens could be detected in both IgAN and healthy control group.Agglutinin inhibition test showed that the specific antigen epitope was N-acetylgalactosamine (GalNAc) residue exposed to galactose deficiency in IgA1 hinged region.There was no significant difference in the absolute levels of plasma IgG antiglycan autoantibodies between IgAN and healthy controls (P=0.963).After adjustment of the plasma level of IgG,the normalized antiglycan autoantibody (ln[IgG antiglycan antibody/IgG]) in patients with IgANwas significantly higher than that in healthy controls (0.58±0.31 vs 0.37±0.11,P ＜ 0.01).The normalized level of IgG antiglycan autoantibody in IgAN patients was positively correlated with 24 h urine protein level during renal biopsy (Spearman r=0.183,P ＜ 0.05),and was also significantly correlated with 24 h urinary protein level after adjusting for baseline clinical and pathological factors (β=0.713,95％CI 0.323-1.102,P ＜ 0.01).The area under ROC curve (AUC) of normalized IgG antiglycan autoantibody in the diagnosis of IgAN was 0.764 (95％ CI 0.682-0.845,P ＜ 0.05).Using the cut-off value of 0.396,the sensitivity and specificity of normalized IgG antiglycan autoantibody for IgAN were 0.729 and 0.700 respectively.There was no significant difference in the absolute or normalized levels of IgA1 antiglycan autoantibodies between IgAN patients and healthy controls.Conclusions Gd-IgA1-specific antiglycan autoantibodies can be detected both in IgAN patients and healthy controls.They are elevated in some patients with IgAN and possibly involved in the development of IgAN.
