Purpose: Nutritional status is related to the clinical outcomes of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The aim of this study was to investigate the association between nutritional status, measured by the prognostic nutritional index (PNI), and adverse hospitalization outcomes in patients with AECOPD.

Methods: Consecutive AECOPD patients admitted to the First Affiliated Hospital of Sun Yat-sen University between January 1, 2015 to October 31, 2021 were enrolled.

Purpose: Previous studies have shown that the red cell index (RCI) can be considered as a simple and useful method to evaluate respiratory function. However, at present its association with adverse hospitalization outcomes in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is not fully understood. Our study aimed to examine the relationship between adverse hospitalization outcomes and RCI among AECOPD patients.

Objective: To explore the role of the interaction between glycogen synthase kinase-3β (GSK-3β) and endoplasmic reticulum stress (ERS) in the high glucose (HG)-induced injury in human umbilical vein endothelial cells (HUVECs).

Methods: HUVECs treated with 40 mmol/L glucose for 24 h were examined for expression levels of GSK-3β, GRP78, CHOP and cleaved caspase-3 protein using Western blotting. The cell viability was examined using CCK-8 assay and cell apoptosis was detected with Hoechst 33258 nuclear staining and photofluorography.

Aims: To investigate the impact of telomerase reverse transcriptase (TERT) gene polymorphism and additional SNP-SNP interaction on non-small cell lung cancer (NSCLC) risk in Chinese population.

Methods: A total of 828 participants (526 males, 302 females), with a mean age of 71.3 ± 15.

Due to the fact that Candida albicans colonizes in the upper respiratory tracts of healthy people, whether or not its isolation from airway secretions is sufficient to warrant treatment remains controversial. The animal models of immunosuppressive rats with pulmonary candidiasis were established by the intratracheal inoculating suspensions of C. albicans, and the animals were divided into the following three groups: (1) antifungal treatment group, (2) saline control group, and (3) blank control group.

Since there is no consensus about the most reliable assays to detect invasive aspergillosis from samples obtained by minimally invasive or noninvasive methods, we compared the efficacy of an enzyme-linked immunosorbent assay (ELISA) for galactomannan (GM) detection and quantitative real-time PCR assay (qRT-PCR) for the diagnosis of invasive pulmonary aspergillosis. Neutropenic, male Sprague-Dawley rats (specific pathogen free; 8 weeks old; weight, 200 ± 20 g) were immunosuppressed with cyclophosphamide and infected with Aspergillus fumigatus intratracheally. Tissue and whole blood samples were harvested on days 1, 3, 5, and 7 post-infection and examined with GM ELISA and qRT-PCR.

Objective: To explore the easily applicable indicators of practical value to evaluate the prognosis of acute respiratory distress syndrome (ARDS).

Methods: Blood and biochemical tests and blood-gas analyses were performed upon entry into the ICUs, 12 h, 24 h, 48 h and 72 h after that in 72 ARDS patients (who were admitted to the ICUs of our hospital from January 2000 to December 2009). Then APACHE II scores were achieved by combining relevant physiological parameters and laboratory results.

Aspergillus fumigatus is an intracellular opportunistic fungus causing invasive pulmonary mycosis, characterised by hyphal invasion and destruction of pulmonary tissue. Th1 cytokines could enhance fungicidal activity. The effects from the combination of interleukin-12 (IL-12) and IL-2 are rarely known in invasive pulmonary aspergillosis infection.

Up to now, there have been few reports concerning changes in lupus activity and immune indices of tuberculosis in patients with systemic lupus erythematosis (SLE). A retrospective investigation was given to survey the case data of SLE patients companied with tuberculosis that were treated in our hospital from 2001 to 2010 and compared with that of sex- and age-matched patients with single SLE. Changes in autoantibodies, lupus activity, inflammatory indices, positive rates of tuberculin (PPD) test and tuberculosis antibody (TB-Ab) of both groups were observed.

Objective: To investigate the risk factors of pulmonary fungal infections related to mechanical ventilation and the prognosis of patients.

Methods: A retrospective case-controlled study was conducted to analyze the culture results of the pulmonary secretions in patients with pulmonary fungal and nonfungal infections in association with mechanical ventilations. The risk factors of pulmonary fungal infections related to mechanical ventilation were identified and their impact on the clinical outcome of the patients was evaluated.

Objective: To study the therapeutic effect of interleukin-2 (IL-2) and interleukin-12 (IL-12) with and without amphotericin B on pulmonary fungal infection of mice.

Methods: A mouse model of pulmonary invasive aspergillus fumigatus (IPA) infection was established and the mice were divided into different groups, treated with IL-2 and IL-12 with and without amphotericin B. The survival number of mice in 15 days and the colony count of lung tissue in the different groups were observed.
