Abstract Background Lung cancer stands as the second most prevalent malignant neoplasm worldwide. Addressing the underlying mechanisms propelling the progression of non-small cell lung cancer is of paramount importance. In this study, we have elucidated the pivotal role of PHF12 in this context. Materials and methods We harnessed clinical lung cancer tissue samples and non-small cell lung cancer cell lines to discern the expression pattern of PHF12. In vitro assays probing cell proliferation were conducted to substantiate the functional impact of PHF12. Furthermore, an in vivo Xenograft model was employed to dissect the role of PHF12. Employing ChIP assays and qRT-PCR, we delved into the intricate binding dynamics between PHF12 and HDAC1. Mechanistic insights into the PHF12-HDAC1 axis in lung cancer progression were pursued via RNA-seq and GSEA analyses. Results Notably, PHF12 exhibited a substantial upregulation within tumor tissue, concomitant with its correlation to HDAC1. The trilogy of cell proliferation assays, transwell assays, and the Xenograft model collectively underscored the promoting influence of PHF12 on lung cancer proliferation, both in vitro and in vivo. The ChIP assay unveiled the transcriptional regulatory role of PHF12 in governing HDAC1 expression. This correlation extended to both mRNA and protein levels. PHF12 promotes NSCLC progression through regulating HDCA1 expression. Intriguingly, the rescue of function within NSCLC cell lines post PHF12 knockdown was achievable through HDAC1 overexpression. Additionally, our findings unveiled the capacity of the PHF12-HDAC1 axis to activate the EGFR/AKT signaling pathway, thereby further corroborating its significance in lung cancer progression. Conclusion Our study identified PHF12 as an oncogenic role in lung cancer proliferation and migration for the first time. PHF12 transcriptionally regulate HDAC1 and activate EGFR/AKT signaling pathway in NSCLC progression. PHF12 may serve as an important target in lung cancer therapy.

Objectives: Few studies illustrate the mechanism between air temperature and blood pressure (BP) in childhood. This study aims to investigate the associations between air temperature, humidity exposure, and BP trajectories in children and adolescents, and explore the potential mediating roles of lipid profiles in these relationships. Methods: This prospective cohort study included 5,971 children with 10,800 person-times measurements at baseline from the Chongqing Health Cohort, with evaluations conducted in 2014–2015 (baseline) and follow-ups in 2016 (urban areas) and 2019 (urban and rural areas). Multilevel mixed-effects models were used to analyse the impacts of air temperature and humidity on BP levels and the incidence of elevated BP, while accounting for potential confounders. Mediation analyses were performed to evaluate the mediating effects of lipid profiles, including low-density lipoprotein (LDL), total cholesterol (TC), and specific lipid species. Results: After adjusting for covariates, higher air temperature quartiles were associated with both decreased BP levels and elevated BP risk (RR: 0.83; 95 % CIs: 0.78, 0.89; P = 0.028). Conversely, higher humidity quartiles exhibited a U-shaped relationship with BP levels. Greater variability in air temperature was linked to increase BP levels. The cumulative effects of air temperature exposure on BP were significant from pregnancy to age 10, with females exhibiting larger effects (β:-3.291, 95 % CIs: −4.242,-2.340, P

Abstract This paper presents a world-leading scintillation light yield among inorganic crystals measured from a 0.5 kg pure-CsI detector operated at 77 Kelvin. Scintillation photons were detected by two 2-inch Hamamatsu SiPM arrays equipped with cryogenic front-end electronics. Benefiting the light yield enhancement of pure-CsI at low temperatures and the high photon detection efficiency of SiPM, a light yield of 30.1 photoelectrons per keV energy deposit was obtained for X-rays and $$\gamma $$ γ -rays with energies from 5.9 to 59.6 keV. Instrumental and physical effects in the light yield measurement are carefully analyzed. This is the first stable cryogenic operation of kg-scale pure-CsI crystal readout by SiPM arrays at liquid nitrogen temperatures for several days. The world-leading light yield opens a door for the usage of pure-CsI crystal in several fields, particularly in detecting the coherent elastic neutrino-nucleus scattering of reactor neutrinos. The potential of using pure-CsI crystals in neutrino physics is discussed in the paper.

Background: Asthma is one of the most prevalent diseases worldwide and is closely related to environmental exposure. The prevalence of asthma and the relationship between asthma and the duration of environmental exposure in adolescents has not been reported in Chongqing, China. Objectives: To examine the prevalence of asthma among adolescents in Chongqing and investigate the relationships between asthma and environmental exposure. Methods: The subjects were recruited from a previous cohort study. The data, demographics and respiratory characteristics were collected after a monthly follow-up visit. PM 2.5 concentrations were matched to the residential addresses of participants. Results: This study included 4146 samples (11.74 ± 0.71 years) and the prevalence of asthma was 3.98 % (165/4146). In terms of PM 2.5 exposure, the annual average PM 2.5 level was significantly higher in adolescents with asthma, and the annual average PM 2.5 was positively associated with asthma (OR = 1.252, 95%CI: 1.049, 1.495). After adjusting for multiple potential confounding factors, comparing with PM 2.5 concentration in the first interquartile range (Q1), seasonal PM 2.5 (OR = 1.791, 95%CI: 1.119, 2.866) and monthly PM 2.5 (OR = 1.484, 95%CI: 0.929, 2.373) in the third interquartile range (Q3), there was a statistically significant increased risk of asthma. In terms of weather-related factors, seasonal humidity (OR = 3.157, 95%CI: 1.168, 8.536), monthly humidity (OR = 2.397, 95%CI: 1.307, 4.397) and temperature (OR = 2.510, 95%CI: 1.157, 5.447), they were positively correlated with asthma. Conclusions: This study illustrated the impact of chronic exposure of PM 2.5, temperature and humidity on asthma in adolescents.
