circZNF124 regulates the proliferation, migration and invasion of colorectal cancer SW620 cells by targeting miR-4262 / 中国临床药理学与治疗学

AIM: To explore the effect and mechanism of circZNF124 on the proliferation, migration and invasion of colorectal cancer SW620 cells. METHODS: The expression levels of circZNF124 and miR-4262 in colorectal cancer tissues were measured by qRT-PCR method. Human colorectal cancer cells SW620 were cultured in vitro, and were randomly grouped into si-NC group, si-circZNF124 group, miR-NC group, miR-4262 group, si-circZNF124 j anti-miR-NC group, si-circZNF124 j antimiR-4262 groups. CCK-8 method, plate clone formation test, scratch test and Transwell test respectively were used to detect cell proliferation, clone formation, migration and invasion of SW620 cells. The dual luciferase reporter experiment analyzed the targeted binding of circZNF124 to miR-4262. Western blot was used to detect the expression of E-cadherin and N-cadherin protein. RESULTS: The expression of circZNF124 in colorectal cancer tissue was increased by about 3.75 times compared with that in the adjacent tissue (P i 0.05), and the expression of miR-4262 was decreased by about 0.73 times compared with the adjacent tissue (P i 0.05). Compared with the si-NC group, the cell viability, scratch healing rate and the protein level of N-cadherin in the si-circZNF124 group were decreased (P i 0.05), the number of cell clone formation and the number of invasive cells were decreased (P i 0.05), while the protein level of E-cadherin was increased (P i 0.05). circZNF124 could negatively regulate the expression of miR-4262. Compared with the miR-NC group, the cell viability, scratch healing rate and the protein level of N-cadherin in the miR-4262 group were reduced (P i 0.05), the number of cell clones and the number of invasive cells were reduced (P i 0.05), while the protein level of E-cadherin was increased (P i 0.05). Inhibition of miR-4262 expression reversed the effect of interfering circZNF124 expression on the proliferation, migration and invasion of SW620 cells.CONCLUSION: Interference with the expression of circZNF124 can attenuate the proliferation, migration and invasion of colorectal cancer cells by targeting miR-4262.

Analysis on current situation and influencing factors of filial piety value among children whose parents were advanced cancer patients / 中国实用护理杂志

Objective:To investigate the filial piety value level and the influencing factors of filial piety among children whose parents were diagnosed as advanced cancer.Methods:A convenient sampling method was used to recruit 383 participants in Tumor Hospital, Tianjin Medical University.Results:The total score of Filial Piety Value Scale among children whose parents were advanced cancer patients was (66.50±4.10) . The age of the patient, the number of hospitalization and the degree of awareness of the condition, the age of the children, whether the child was the-only-child, whether the child was living with the patient, and the average daily care time influenced the filial piety values of children whose parents were advanced cancer patients ( Z=16.64-62.94, U=2.04-4.27, P<0.05). Conclusion:Children whose parents were with advanced cancer have a better understanding of filial piety. Nurses understand the values of filial piety of children in the context of traditional filial piety and family care mode in China, which can enhance the experience of filial piety and filial piety of both children and parents, also improve the mental health problems of patients, and finally improve the quality of life of patients with advanced cancer.

Dose-Dense Rituximab-CHOP versus Standard Rituximab-CHOP in Newly Diagnosed Chinese Patients with Diffuse Large B-Cell Lymphoma: A Randomized, Multicenter, Open-Label Phase 3 Trial / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone administered every 3 weeks (R-CHOP-21) is the standard care for diffuse large B-cell lymphoma (DLBCL). It is unknown whether the dose-dense R-CHOP (R-CHOP-14) could improve the outcome of the disease in Asian population. MATERIALS AND METHODS: Newly diagnosed DLBCL patients were centrally, randomly assigned (1:1) to receive R-CHOP-14 or R-CHOP-21. R-CHOP-14 was administered every 2 weeks, and R-CHOP-21 was administered every 3 weeks. Primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS), progression-free survival (PFS), response rate and toxicities. RESULTS: Seven hundred and two patients were randomly assigned to receive R-CHOP-14 (n=349) or R-CHOP-21 (n=353). With a median follow-up of 45.6 months, the two groups did not differ significantly in 3-year DFS (79.6% for R-CHOP-14 vs. 83.2% for R-CHOP-21, p=0.311), 3-year OS (77.5% for R-CHOP-14 vs. 77.6% for R-CHOP-21, p=0.903), or 3-year PFS (63.2% for R-CHOP-14 vs. 66.1% for R-CHOP-21, p=0.447). Patients with an International Prognostic Index (IPI) score ≥ 2 had a poorer prognosis compared to those with an IPI score < 2. Grade 3/4 hematologic and non-hematologic toxicities were manageable and similar between R-CHOP-14 and R-CHOP-21. CONCLUSION: R-CHOP-14 did not improve the outcome of DLBCL compared to R-CHOP-21 in Asian population. With manageable and similar toxicities, both of the two regimens were suitable for Asian DLBCL patients. For high-risk patients with IPI ≥ 2, new combination regimens based on R-CHOP deserve further investigation to improve efficacy.

The Status research of ICU Nurses career situations of tertiary general hospital in Shangdong Province / 中国实用护理杂志

Objective To understand the status quo of ICU nurses career situations and its influencing factors in Shandong province. Methods A total of 247 ICU nurses were investigated by questionnaires on career condition. Results The career condition score was 79.19 ± 11.63. In addition, statistical significances were revealed by occupational career questionnaire of ICU nurses in different aspect of the scores with age, gender, working years in the ICU, access years to ICU nurses specialist, whether to participate in career training. The scores of career condition and career identity ICU nurses were different, the 40-years-older group was higher than 31-40 years group (P=0.007, P=0.005). The dimension scores of male nurses organizational commitment was higher than that of female nurses(P=0.002). The scores of career condition whose ICU working life more than 16 years were higher than those of within 5 years(P=0.013). The career condition scores of the ICU nurses with access years of specialist qualifications 7-9 years was higher than those of within 3 years(P=0.011). Conclusions The career condition score of ICU clinical nurse specialists was at a medium level, it still needs to be further improved, managers should pay attention to the different levels of nurses to provide career training, in order to promote the professional development of critical care nurses.

Effect of darbufelone on the proliferation and apoptosis of SGC-7901 cell line / 中国药理学通报

Aim To investigate the effects of dual COX-2/5-LOX inhibitor darbufelone on the inhibition of gastric adenocarcinoma in vitro.Methods MTT assay was used to detect the inhibition of gastric adenocarcinoma cell line SGC-7901 by darbufelone in different concentrations and at different times.TUNEL staining was used to evaluate the apoptosis of SGC-7901 cells.The changes of 5-LOX and COX-2 mRNA expression were studied by reverse transcription polymerase chain reaction.5-LOX and COX-2 protein expressions were analyzed by immunocytochemistry in SGC-7901 cells.Results darbufelone could decrease the proliferation significantly in a dose-dependent and time-dependent manner in SGC-7901 cells.After treating SGC-7901 with darbufelone at concentration of 1.5?10-5,1.0?10-5,5?10-6 mol?L-1 for 72 hs,apoptosis index(%) of SGC-7901 was(30.3?2.1)%,(23.0?2.0)%,(15.0?1.5)%,respectively,which was significantly higher than(0.6?0.1)% that in control group(P
