Clinical Characteristics Analysis of 30 Cases of Interferon-γ Autoantibody-Positive Patients with Concurrent Mycobacterial Infection: A 6-Year Retrospective Study.

Purpose: This study aimed to investigate and elucidate the clinical characteristics, immune status, infection types and patterns, treatment responses, and disease progression in patients with positive anti-interferon-gamma (IFN-γ) autoantibodies in combination with Mycobacterium infections.

Patients And Methods: We conducted a retrospective analysis of clinical data from patients with positive anti-IFN-γ autoantibodies and concurrent Mycobacterial infections, including Mycobacterial infections (MTB) and non-tuberculous mycobacteria (NTM). The study included cases treated at the Fourth People's Hospital of Nanning, Guangxi, from 2018 to 2023.

Single-cell analysis of diverse immune phenotypes in malignant pleural effusion.

The complex interactions among different immune cells have important functions in the development of malignant pleural effusion (MPE). Here we perform single-cell RNA sequencing on 62,382 cells from MPE patients induced by non-small cell lung cancer to describe the composition, lineage, and functional states of infiltrating immune cells in MPE. Immune cells in MPE display a number of transcriptional signatures enriched for regulatory T cells, B cells, macrophages, and dendritic cells compared to corresponding counterparts in blood.

[Effect of Pongamia pinnata root flavonoids on the quality of ulcer healing and expression of EGF and TGF-alpha in the rat model of gastric ulcer induced by acetic acid].

Objective: To observe the effects and mechanisms of Pongamia pinnata root flavonoids (PRF) on the experimental gastric ulcer induced by acetic acid and to study the mechanism of PRF on the quality of ulcer healing.

Methods: The models were established by acetic acid erosion, the quality of ulcer healing of PRF on the model of gastric ulcer were observed. The contents of epidermal growth factor (EGF) in serum were determined by radioimmunoassay.
