BACKGROUND: Peripheral helper T (T PH ) cells are uniquely positioned within pathologically inflamed non-lymphoid tissues to stimulate B-cell responses and antibody production. However, the phenotype, function, and clinical relevance of T PH cells in hepatocellular carcinoma (HCC) are currently unknown. METHODS: Blood, tumor, and peritumoral liver tissue samples from 39 HCC patients (Sep 2016-Aug 2017) and 101 HCC patients (Sep 2011-Dec 2012) at the Third Affiliated Hospital of Sun Yat-sen University were used. Flow cytometry was used to quantify the expression, phenotype, and function of T PH cells. Log-rank tests were performed to evaluate disease-free survival and overall survival in samples from 39 patients and 101 patients with HCC. T PH cells, CD19 + B cells, and T follicular helper (T FH ) cells were cultured separately in vitro or isolated from C57/B6L mice in vivo for functional assays. RESULTS: T PH cells highly infiltrated tumor tissues, which was correlated with tumor size, early recurrence, and shorter survival time. The tumor-infiltrated T PH cells showed a unique ICOS hi CXCL13 + IL-21 - MAF + BCL-6 - phenotype and triggered naïve B-cell differentiation into regulatory B cells. Triggering programmed cell death protein 1 (PD-1) induced the production of C-X-C motif chemokine ligand 13 (CXCL13) by T PH cells, which then suppressed tumor-specific immunity and promoted disease progression. CONCLUSION Our study reveals a novel regulatory mechanism of T PH cell-regulatory B-cell-mediated immunosuppression and provides an important perspective for determining the balance between the differentiation of protumorigenic T PH cells and that of antitumorigenic T FH cells in the HCC microenvironment.

A self-supervised super-resolution reconstruction method based on scale adaptive and coordinate encoding is proposed to realize super-resolution reconstruction of anisotropic brain magnetic resonance images with different slice thicknesses even in the absence of paired isotropic brain magnetic resonance images.Firstly,an image encoding module that integrates super-resolution scale information is used to learn the specific features of images with different slice thicknesses.Subsequently,a coordinate encoding module is employed to facilitate the deep fusion of coordinate information and image features.Finally,an overall loss function comprising reconstruction loss and brain tissue edge perception loss is adopted to optimize the recovery of edge high-frequency information,while global residual learning is introduced to enhance network training.Experimental results on the HCP-1200 and OASIS-1 datasets demonstrate that the proposed method outperforms other self-supervised super-resolution reconstruction methods.

Objective It aims to investigate the status quo of nurses'emotional exhaustion in tertiary public hospitals in China and analyze its influencing factors,so as to provide suggestions for formulating targeted policy measures to reduce nurses'emotional exhaustion.Methods Relying on the fifth"The Third-Party Evaluation of the China Healthcare Improvement Initiatives"project,it surveyed nurses from 143 tertiary public hospitals across 31 provinces(including autonomous regions and municipalities)and the Xinjiang Production and Construction Corps.Univariate analyses were performed using the Pearson chi-square test.Multifactorial analyses were performed using ordered multicategorical logistic regression analysis.Results The score of nurses'emotional exhaustion in tertiary public hospitals in China was 8.00(2.00～16.00),of which mild exhaustion accounted for 79.00％,moderate exhaustion accounted for 10.00％,and severe exhaustion accounted for 11.00％.Gender,age,number of children,region,type of hospital,department,employment form,assume scientific research task,excessive workload,salary and hospitals carry out psychological guidance were the influencing factors of nurses'emotional exhaustion.Conclusion Nurses in tertiary public hospitals in China are at a mild level of emotional exhaustion,but in some groups the degree is more serious.Policy makers and hospital managers should focus on special groups,implement the reform of salary system,reduce nurses'workload,reasonably arrange working hours,improve the working environment of hospitals,and strengthen nurses'psychological guidance.
