Inhibition of lncRNA KCNQ1OT1 Improves Apoptosis and Chemotherapy Drug Response in Small Cell Lung Cancer by TGF-β1 Mediated Epithelial-to-Mesenchymal Transition / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. @*Materials and Methods@#In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. @*Results@#The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. @*Conclusion@#Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.

Mediating effect of resilience and depression between social support and self-neglect in empty-nest community-dwelling elderly / 中华行为医学与脑科学杂志

Objective:To explore the mediating effects of resilience and depression on the relationship between social support and self-neglect.Methods:From July to October 2020, a cross-sectional survey was conducted among 549 empty-nest community-dwelling elderly in the community using the social support rating scale, Connor and Davidson resilience scale, geriatric depression scale and elderly self-neglect scale. SPSS 22.0 and AMOS 24.0 were used for data analysis, including descriptive analysis, correlation analysis and structural equation modeling.Results:The scores of social support, resilience and self-neglect of the empty-nest elderly were (38.63±7.47), (64.30±14.57) and (3.72±2.67) respectively, and 31.70% (174/549) of the subjects had depressive symptoms. The score of self-neglect was negatively correlated with the score of social support ( r=-0.597, P<0.01) and resilience ( r=-0.557, P<0.01), and positively correlated with depression score ( r=0.675, P<0.01). The score of social support was positively correlated with resilience score ( r=0.531, P<0.01) and negatively correlated with depression ( r=-0.597, P<0.01). Social support could affect self-neglect directly ( β=-0.485, P<0.05), and it could also influence self-neglect indirectly through the partial mediating effect of resilience ( β=-0.451, P<0.05). The mediating effect of resilience and depression accounted for 12.18% and 36.00% of the total effects respectively. Conclusion:Social support could influence self-neglect directly or indirectly through resilience and depression. The empty-nesters should be encouraged to participate more in social activities so as to improve their resilience, reduce the occurrence of self-neglect.

Establishment of A Patient-derived Xenotransplantation Animal Model for Small Cell Lung Cancer and Drug Resistance Model / 中国肺癌杂志

BACKGROUND@#Small cell lung cancer (SCLC) is characterized by poor differentiation, high malignancy and rapid growth fast, short double time, early and extensive metastatic malignancy. In clinical, chemotherapy is the main treatment method, while resistance to multiple chemotherapy drugs in six to nine months has been a major clinical challenge in SCLC treatment. Therefore, It has important clinical value to building SCLC aninimal model which is similar to patients with SCLC. Animal model of xenotransplantation (PDX) from the patients with small cell lung cancer can well retain the characteristics of primary tumor and is an ideal preclinical animal model. The study is aimed to establish SCLC PDX animal model and induce the chemoresistance model to help to study the mechanism of chemoresistance and individual treatment.@*METHODS@#Fresh surgical excision or puncture specimens from SCLC patients were transplanted into B-NSGTM mice subcutaneous tissues with severe immunodeficiency in one hour after operation the B-NSGTM mice subcutaneous in 1 hour, and inject chemotherapy drugs intraperitoneally after its tumor growed to 400 mm³ with EP which is cisplatin 8 mg/kg eight days and etoposide 5 mg/kg every two days until 8 cycles. Measure the tumor volum and mice weights regularly, then re-engrafted the largest tumor and continue chemotherapy.@*RESULTS@#Nine cases were conducted for B-NSG mice modeling. Three of nine cases could be engrafted to new B-NSG mice at least two generation. The SCLC PDX animal models have been established successfully. After adopting chemotherapy drugs, the chemoresistance PDX models have been established. High homogeneity was found between xenograft tumor and patient's tumor in histopathology, immunohistochemical phenotype (Syn, CD56, Ki67).@*CONCLUSIONS@#The SCLC PDX animal model and the chemoresistance PDX animal model have been successfully constructed, the success rate is 33%, which provides a platform for the clinical research, seeking for biological markers and choosing individual treatment methods of SCLC.

Current status of professional identity among undergraduates majoring in public affairs management and the related influencing factors / 中华医学教育探索杂志

Objective@#To investigate the current status of professional identity among the undergraduates majoring in public affairs management and the related influence factors.@*Methods@#A stratified cluster sampling method was used to conduct a questionnaire survey among the 115 undergraduates majoring in public affairs management in a medical university in Harbin, China, and the contents of the questionnaires included general status and professional identity. The t-test, one-way analysis of variance, and multiple linear regression analysis were used to analyze the influencing factors of professional identity. In-depth interviews were conducted for some students to explore the profound influencing factors for professional identity among the students majoring in public affairs management.@*Results@#The overall level of professional identity was low among the undergraduates majoring in public affairs management in the medical university in Harbin, and the score of professional identity was 3.25±0.56. The scores of cognitive dimension, emotional dimension, behavioral dimension, and applicable dimension were 3.41±0.69, 3.21±0.78, 3.24±0.71, and 3.13±0.72, respectively. The multivariate analysis showed that grade, academic performance, major selection, and children number in family had significant influence on their professional identity. The students who were at grade four, who had high academic record (b=-0.276, P<0.01), who chose this major independently (b=-0.277, P<0.01), and who were the only child (b=-0.233, P<0.05) had a high score of professional identity. As for the undergraduates at different grades, the undergraduates at grades two and three had a significantly lower score of professional identity than those at grade four (b=-0.296 and -0.369, P<0.05), while there was no significant difference between the undergraduates at grades one and four (b=-0.008, P>0.05). Furthermore, the students with a high score of professional identity had higher possibility to pursue the job related to this major than those with a low score (3.39±0.53 vs. 2.92±0.49, t=4.414, P<0.01).@*Conclusion@#Universities should strengthen the publicity of the major of public affairs management, optimize the curriculum, and add job experience, so as to enhance professional identity among students with this major and provide talent for the field of public health management.
