45, 95% CI [1.01, 2.09], p = 0.043) and CM4 but not significant (HR [95% CI] 1.29 [0.91, 1.83], p = 0.15). Adjusted odds of more rapid control within 6 months were twofold higher for CM2 (p = 0.04) and CM4 (p = 0.055), respectively, versus CM1. CM2 did not differ from CM1. DM control was less likely for CM by telephone only than face-to-face in clinic. To benefit vulnerable patients with uncontrolled DM, in-person engagement may be required.Purpose Cytokines are vital pro-inflammatory factors and involved in tumor immune infiltration, and immune infiltration is closely related to PD-1/PD-L1 blockades immunotherapy. selleck kinase inhibitor This study aims to explore the associations between cytokines and prognosis and also PD-1/PD-L1 expression in early lung adenocarcinoma, which is seldom reported. Methods 324 early lung adenocarcinoma patients with prior surgical resection were included and the associations between overall survival time and clinical factors and also cytokines including IL-1β, IL-6 and TNF-α were analyzed by multivariate cox regression and Kaplan-Meier curve (log-rank test). Resected tumor samples were randomly obtained to detect the PD-1/PD-L1 expression by immunohistochemistry, and Chi square test was used for relations between cytokines and PD-1/PD-L1 expression. Results In this study group, 26.2% patients showed a high level of IL-1β and patients with high IL-1β level showed 19 months shortened mOS than those with normal IL-1 β expression (mOS 24.00, 95%CI 11.98-36.02 vs 43.00, 95% CI 37.37-48.63, p = 0.017). Among detected samples, the positive rate of PD-1 was 25.0% (13/52), and the positive rate of PD-L1 was 37.3% (19/52). The positive rate of PD-1 was 36.1% higher in high-IL-1 β-level group as compared to normal-IL-1β-level group (50.0% vs 13.9%, p = 0.012). No significant association was found between IL-1 β and PD-L1 expression. Conclusion High expression level of IL-1β was correlated with poor prognosis and higher positive rate of PD-1 expression, which gave us insights into biomarkers of survival prediction and immunotherapy in lung adenocarcinoma. Further studies were still needed.Purpose The prognosis of AML patients with chemotherapy is poor, especially those who are insensitive to and resistant to chemotherapy drugs. To clarify the underlying pathogenesis of AML and provide new therapeutic targets for clinical treatment, we explore the role of circRNA in leukemia. Methods High-throughput circRNA sequencing analysis was performed in patients with leukemia and healthy donors. RT-qPCR and western blot analysis were used to determine expression of GSK3β. RNA pull-down assay was used to detect miRNAs pulled down by hsa_circ_0121582. RNA immunoprecipitation assay was performed to evaluate the binding capacity between TET1 and hsa_circ_0121582. Results A new and highly stable circRNA was found, which was derived from the reverse splicing of GSK3β exon 1 to exon 7, and hsa_circ_0121582 was down-regulated in leukemia cells. In gain-of-function experiments, the up-regulated hsa_circ_0121582 inhibited the proliferation of leukemia cells in vitro and in vivo. In the cytoplasm, hsa_circ_0121582 could act as a sponge for miR-224, attenuate the inhibiting effect of miR-224 on GSK3β, and thus up-regulate the expression level of GSK3β. In addition, hsa_circ_0121582 could bind to GSK3β promoter in the nucleus, and recruit DNA demethylase TET1 to ensuring the transcription of GSK3β. The upregulated GSK3β inhibited the Wnt/β-catenin signaling pathway, and reduced the aggregation of β-catenin in the nucleus, thus inhibited the proliferation of leukemia cells. Conclusions This study found that hsa_circ_0121582 was involved in the inhibition of tumor proliferation, and the restoration of hsa_circ_0121582 could be an effective treatment strategy for patients with leukemia.Purpose The COVID-19 pandemic has forced healthcare stakeholders towards challenging decisions. We analyse the impact of the pandemic on the conduct of phase I-II trials for paediatric cancer during the first month of state of alarm in Spain. Methods A questionnaire was sent to all five ITCC-accredited Spanish Paediatric Oncology Early Phase Clinical Trial Units, including questions about impact on staff activities, recruitment, patient care, supply of investigational products, and legal aspects. Results All units suffered personnel shortages and difficulties in enrolling patients, treatment continuity, or performing trial assessments. Monitoring activity was frequently postponed (73%), and 49% of on-going trials interrupted recruitment. Only two patients could be recruited during this period (75% reduction in the expected rate). Conclusions The COVID-19 crisis has significantly impacted clinical research practice and access to innovation for children with cancer. Structural and functional changes are under way to better cope with the expected future restrictions.Purpose To investigate the effect of shRNA-regulated S100A4 expression on the proliferation and apoptosis in KLE endometrial cancer cells. Methods S100A4-OVER and S100A4-shRNA were transfected into KLE endometrial cancer cells using lentiviral sh-RNA technology. Passive OVER-NC cell line and shRNA-NC cell line were used as a negative control group and non-transfected Control cell line as a blank control group. After 48 h of transfection, the expressions of S100A4 and protein were detected by real-time fluorescence quantitative PCR and Western blotting, respectively. CCK-8 detection and flow cytometer were used to detect cell proliferation and apoptosis, respectively. Results Compared with the normal control group and the negative control group, the transfection efficiency and shRNA targeting of the shRNA-interfered S100A4 gene were verified at the levels of mRNA and protein expression. The expression of the disrupted S100A4 gene at S100A4 mRNA and protein levels in endometrial cancer cells was determined. The proliferation efficiency of KLE cells in S100A4-OVER group was significantly higher than that in other four groups; the proliferation rate of S100A4-shRNA cells decreased slightly;, the apoptotic rate of KLE cells in S100A4-shRNA group increased significantly, and the apoptotic rate of KLE cells in S100A4-OVER group decreased compared with NC group. Conclusion Specific regulation of S100A4 gene expression, the enhanced expression of the S100A4 gene may promote the proliferation of KLE endometrial cancer cells; the inhibited expression of the S100A4 gene may promote the apoptosis of KLE endometrial cancer cells. S100A4 expression is closely related to the biological characteristics of endometrial cancer.
