Background To explore the status of postoperative psychological stress and the expression of stress-related factors heat stress protein 70 (HSP70) and interferon γ (IFN-γ) in patients with early lung cancer, and to provide scientific basis for psychological rehabilitation and index detection of patients with lung cancer. Methods Patients with early lung cancer hospitalized in People's Hospital of Rizhao from April 2014 to March 2017 were selected as the research subjects, and a cross-sectional survey research method was used to conduct a questionnaire survey on the research subjects. The questionnaire included General Data Questionnaire and the SCL-90 Self-Assessment Scale for Health Symptoms, which were used to research the postoperative psychological stress of patients with early lung cancer. The enzyme-linked immunosorbent assay was used to detect the serum levels of HSP70 and IFN-γ. Results A total of 178 patients with early lung cancer were investigated, including 126males (70.8%) and 52 females (29.2%).ors HSP70 and IFN-γ in patients with different levels of psychological stress, which are of certain clinical value as the monitoring index of response psychological stress.Background To illustrate the role of DERL3 in regulating the development of Colorectal cancer (CRC) and the underlying molecular mechanisms. Methods Relative levels of DERL3 in CRC tissues and adjacent normal ones were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The relationship between DERL3 level and clinical indicators in CRC patients was analyzed by Chi-square test. After intervening DERL3 level in HT29 and HCT-8 cells, phenotype changes were assessed by cell counting kit-8 (CCK-8) and Transwell assay. The interaction between DERL3 and its downstream target MYCN, and their involvement in the malignant development of CRC were explored. SF1670 concentration The influence of DERL3 on in vivo growth of CRC was determined by establishing xenograft model in nude mice bearing CRC. Results DERL3 was lowly expressed in CRC tissues than adjacent normal ones. Compared with CRC patients expressing a high level of DERL3, those with a low level presented high rate of lymphatic metastasis or distant metastasis. Overexpression of DERL3 in HT29 cells suppressed proliferative, migratory and invasive capacities, and knockdown of DERL3 in HCT-8 cells yielded the opposite results. MYCN was the downstream target binding DERL3, which was upregulated in CRC tissues and cell lines. MYCN was capable of reversing the regulatory effects of DERL3 on proliferative, migratory and invasive capacities in CRC cells. In vivo overexpression of DERL3 in nude mice bearing CRC inhibited tumor growth by reducing the average tumor volume and tumor weight of CRC tissues. Conclusions DERL3 is downregulated in CRC samples. Its level is closely linked to lymphatic metastasis or distant metastasis rate in CRC patients. Through negatively regulating MYCN level, DERL3 suppresses proliferative, migratory and invasive capacities in CRC.Background To uncover the clinical significance of LINC00858 in the development of Wilms' tumor and the potential molecular mechanism. Methods LINC00858 levels in Wilms' tumor species and cell lines were determined by quantitative real-time polymerase chain reaction (qRT-PCR). The clinical significance of LINC00858 in influencing pathological features and prognosis in patients with Wilms' tumor was analyzed. Proliferative and migratory changes in Wilms' tumor cells with LINC00858 knockdown were assessed. The downstream gene of LINC00858 was verified by luciferase assay, and its involvement in the development of Wilms' tumor was further explored. Results LINC00858 was highly expressed in Wilms' tumor tissues and cell lines. High level of LINC00858 was correlated to high rate of lymphatic metastasis and poor prognosis in patients with Wilms' tumor. Knockdown of LINC00858 suppressed proliferative and migratory potentials in HFWT and 17-94 cells. MiR-653-5p was targeted by LINC00858. It was lowly expressed in Wilms' tumor tissues and negatively regulated by LINC00858. Knockdown of miR-653-5p partially abolished the regulatory effects of LINC00858 on proliferative and migratory potentials in Wilms' tumor cells. Conclusions LINC00858 is highly expressed in Wilms' tumor species, and correlated to lymphatic metastasis rate and overall survival in patients with Wilms' tumor. Knockdown of LINC00858 suppresses Wilms' tumor cells to proliferate and migrate via targeting miR-653-3p.Background Although esophageal pressure measurement could help clinicians to improve the ventilatory management of ARDS patients, it has been mainly used in clinical research. Aim of this study was to compare the measurements of end-expiratory esophageal pressure, end-expiratory transpulmonary pressure and lung stress by three systems a dedicated manual device, taken as gold standard, a new automatic system (Optivent) and a bedside equipment, consisting of a mechanical ventilator and a hemodynamic monitor. Methods In sedated and paralyzed mechanically ventilated ARDS patients the esophageal pressure was measured at three PEEP levels in random fashion (baseline level, 50% higher and 50% lower). Results Forty patients were enrolled (BMI 25 [23-28] Kg/m2, PaO2/FiO2 187 [137-223] and PEEP 9±3 cmH2O). The mean esophageal pressure measured during an expiratory pause by the dedicated system, the bedside system and Optivent were 10.0 ± 4.2, 10 ± 4 and 9.9 ± 4.0 cmH2O, respectively. The respective bias and limits of agreement between the dedicated system and Optivent and between the dedicated system and the bedside system were as follows end-expiratory esophageal pressure, 0.2 cmH2O, (-0.4 to 0.9) and -0.1 cmH2O (-1.9 to 1.7); end-expiratory transpulmonary pressure, -0.6 cmH2O (-1.7 to 0.4) and -0.4 cmH2O, (-2.2 to 1.5); lung stress -0.9 cmH2O (-3.0 to 1.1) and -1.5 cmH2O (-4.4 to 1.4). Conclusions Both Optivent and the bedside system showed clinically acceptability if compared to the gold standard device. The possibility to apply one of these systems could allow a wider use of esophageal pressure in clinical practice.
