Serum sphingolipids aid in diagnosing adult HIV-negative patients with pulmonary cryptococcosis: a clinical cohort study.

Background: Pulmonary cryptococcosis (PC) contributes to the ongoing global disease burden in human immunodeficiency virus (HIV)-negative populations. Since some PC patients are misdiagnosed under existing diagnostic guidelines, new diagnostic markers are needed to improve diagnostic accuracy and therapeutic efficacy and reduce disease risk.

Methods: Our previously established sphingolipidomic approach was employed to explore the use of serum sphingolipids (SPLs) in diagnosing HIV-negative patients with PC.

Case Report: Nintedanib for Pembrolizumab-Related Pneumonitis in a Patient With Non-Small Cell Lung Cancer.

Pembrolizumab, an immune checkpoint inhibitor (ICI) approved for advanced non-small cell lung cancer (NSCLC) treatment, has shown superior survival benefits. However, pembrolizumab may lead to severe immune-related adverse events (irAEs), such as checkpoint inhibitor-related pneumonitis (CIP). The routine treatment of CIP was based on systemic corticosteroids, but the therapies are limited for patients who are unsuitable for steroid therapy.

Anlotinib Plus S-1 for Patients with EGFR Mutation-Negative Advanced Squamous Cell Lung Cancer with PS Scores of 2-3 After Progression of Second-Line or Later-Line Treatment.

Objective: The study aimed to analyze the efficacy and safety of combination regimen of anlotinib and S-1 for Chinese patients with EGFR mutation-negative advanced squamous cell lung cancer (SqCLC) with poor performance status (PS,2-3) after progression of second-line or later-line chemotherapy.

Methods: Clinical data of 70 SqCLC patients with PS scores of 2-3 treated in the First Affiliated Hospital of Guangzhou Medical University between January 1, 2018 to September 31, 2019 who failed second- or more-line treatment were analysed retrospectively. The patients were divided into two treatment groups: anlotinib (12mg) plus S-1 (25mg) combination group and anlotinib (12mg) monotherapy group.

Clinical features, treatment, and survival outcome of primary pulmonary NUT midline carcinoma.

Objective: NUT midline carcinoma (NMC), a rare type of squamous cell carcinoma, is genetically characterised by NUT midline carcinoma family member 1 (NUTM1) gene rearrangement. NMC can arise from the lungs; however, there is no standard for the management of primary pulmonary NMC. This study aimed to confirm the clinical features and report the treatments, especially with immune checkpoint inhibitors (ICIs), and outcomes of patients with primary pulmonary NMC.

Case report: dermatomyositis associated with lung cancer with heterogeneous morphology.

Dermatomyositis (DM) complicated with non-small cell lung cancer (NSCLC) is not rare, and could rapidly develop into severe lung cancer [performance-status score (PS) between 2 and 4]. Moreover, tumor has remarkable heterogeneity, and it is not possible to properly target treatments in cases of relapse without knowing pathological diagnosis. We retrospectively analyzed the diagnosis and treatment of a patient with DM complicated with NSCLC, which developed into severe lung cancer with heterogeneity of the tumor during chemotherapy.

CYP1A1 MspI polymorphisms and lung cancer risk: an updated meta-analysis involving 20,209 subjects.

Published data describing the association between CYP1A1 MspI gene polymorphism and lung cancer risk are inconclusive. To determine a more conclusive relationship, we performed an updated meta-analysis of all eligible studies and conducted the subgroup analysis by stratification according to the ethnicity source, histological types of lung cancer, gender and smoking status of case and control populations. A total of 51 studies comprising 20,209 subjects were included in the analysis.

[Effect of heparin upon inflammatory reaction of endotoxin-induced acute lung injury in rat].

Objective: To investigate the effects of heparin upon inflammatory reaction and associated mechanism of endotoxin-induced acute lung injury (ALI) in rat.

Methods: Thirty-six male Sprague-Dawley rats were randomly divided into three equal groups namely: ALI group, heparin treatment group and normal control group. The ALI rats were induced by injecting endotoxin intravenously and sacrificed at 4 h after model establishment.

Antithrombin-III without concomitant heparin improves endotoxin-induced acute lung injury rats by inhibiting the activation of mitogen-activated protein kinase.

Background: Antithrombin-III (AT-III), the major inhibitor of thrombin in plasma, also has anti-inflammation property and might have positive effect on sepsis. The present study aimed to investigate the effects of AT-III on inflammatory reaction and pulmonary protection in endotoxin-induced acute lung injury (ALI) rat.

Methods: Sixty male Sprague-Dawley rats were randomly assigned equally to normal control group, ALI group, AT-III treatment group, AT-III + heparin treatment group, and heparin treatment group.

Prognostic value of vascular endothelial growth factor expression in patients with lung cancer: a systematic review with meta-analysis.

Background: Vascular endothelial growth factor (VEGF) has been implicated in tumorigenesis and metastasis, and it presumably mediates the proliferation of endothelial cells and promotes vascular permeability. However, the prognostic value of VEGF overexpression in patients with lung cancer remains controversial.

Methods: Survival data from published studies were aggregated following a methodological assessment.
