Immunotherapy combined with chemotherapy without locoregional radiotherapy in metastatic nasopharyngeal carcinoma: two case reports and a literature review.

Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.

To analyze the efficacy of endoscopic CO₂ laser arytenoidectomy in treating bilateral vocal cord paralysis. Ninety-five patients who underwent endoscopic CO₂ laser arytenoidectomy for bilateral vocal cord paralysis at the First Affiliated Hospital of Naval Medical University（Changhai Hospital） of Shanghai from January 2009 to December 2022 were included in this study. Among them, 59 patients underwent endoscopic CO₂ laser arytenoidectomy as their first glottic enlargement surgery（Group A）, while 36 patients, who had previously undergone two unsuccessful CO₂ laser-assisted posterior cordotomies, underwent endoscopic CO₂ laser arytenoidectomy as a subsequent surgery（Group B）.

[The key problems of diagnosis and treatment of vocal cord paralysis].

Vocal cord paralysis is a common condition that significantly impairs laryngeal function and can even be life-threatening. Over nearly a century, researchers have conducted extensive animal and clinical studies to achieve accurate diagnosis and restore laryngeal function, making significant progress. Approaches have evolved from mechanically narrowing the glottis to restore phonation, to enlarging the glottis to relieve breathing difficulties, and ultimately to the development of surgical techniques aimed at restoring vocal cord mobility, significantly advancing the field.

Neoadjuvant chemoimmunotherapy for laryngeal preservation in locally advanced hypopharyngeal cancer.

Objectives: To retrospectively investigate the pathological response rate, laryngeal preservation surgery (LPS) rate and progression free survival (PFS) of neoadjuvant chemoimmunotherapy in the treatment of locally advanced hypopharyngeal cancer (LAHPC).

Materials And Methods: In this study, LAHPC patients, who were first diagnosed and underwent surgery at the First Affiliated Hospital of Naval Medical University between January 2021 and January 2024, preoperatively administered PD-1 inhibitor and TP induction regimen (albumin-bound paclitaxel 260 mg/m and cisplatin 80 mg/m). The primary endpoint was major pathological response (MPR), with ORR rate, LPS rate and PFS as the secondary endpoints.

Role of tympanocentesis in the prevention of middle ear barotrauma induced by fast buoyant ascent escape from 200 m underwater.

Introduction: We aimed to study middle ear barotrauma caused by fast compression followed by buoyant ascent escape from 200 m underwater and its effect on the auditory system, and to validate the preventive effect of tympanocentesis on middle ear barotrauma.

Methods: Twenty Sprague Dawley rats were divided into two groups: rats in group A underwent a simulated fast buoyant ascent escape from a depth of 200 m, while those in group B underwent tympanocentesis before the procedure described for group A. Ear endoscopy, acoustic conductance, and auditory brainstem response (ABR) tests were conducted before and after the procedure to evaluate the severity of middle ear barotrauma and auditory function in both groups.

Long noncoding RNA MALAT1 as a ceRNA drives mouse fibroblast activation via the miR-335-3p/P2ry2 axis.

Fibrosis is a complex pathological process that can lead to the permanent loss of biological function, with P2ry2 playing a crucial role in this process. Long non-coding RNAs (lncRNAs) have been reported to play an critically important role in the fibrotic process. However, it remains unclear whether lncRNAs can regulate fibrosis through P2ry2.

Identification of ENTPD1 as a novel biomarker linking allergic rhinitis and systemic lupus erythematosus.

Several studies reveal that allergic rhinitis (AR) is a significant risk factor of systemic lupus erythematosus (SLE). However, studies investigating the common pathogenesis linking AR and SLE are lacking. Our study aims to search for the shared biomarkers and mechanisms that may provide new therapeutic targets for preventing AR from developing SLE.
