Efficacy and safety of different inhaled corticosteroids for bronchopulmonary dysplasia prevention in preterm infants: A systematic review and meta-analysis.

Background: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of inhaled corticosteroids (budesonide, beclomethasone, or fluticasone propionate) in preventing bronchopulmonary dysplasia (BPD) for premature infants.

Method: Electronic databases, including PubMed, EMBASE, Web of science, Scopus, and Cochrane library, were searched from databases inception to January 2022 for eligible randomized controlled trials. Clinical outcomes such as BPD, mortality, BPD or death, adverse events, and neurodevelopmental outcomes were assessed.

Innate Immune Evasion by Human Respiratory Syncytial Virus.

Respiratory syncytial virus (RSV) is the leading cause of severe respiratory infection in young children. Nearly all individuals become infected in their early childhood, and reinfections with RSV are common throughout life. Primary infection with RSV is usually involved in the symptom of bronchiolitis and pneumonia in the lower respiratory tract, which accounts for over 3 million hospitalizations and approximately 66,000 deaths annually worldwide.

The diterpenoid adenanthin upregulates the expression of natural killer group 2D receptor ligands in hepatocellular carcinoma cells.

Objective: The natural killer (NK) group 2D (NKG2D) receptor plays a crucial role in NK cell-mediated anti-tumor immunity. NKG2D anti-proliferative effect is mediated by direct interactions of the receptor with its ligands that may be considered as a potential target for NK-based immunotherapeutic strategy in cancer cells.

Methods: Here we report that a natural product adenanthin significantly promotes NKG2D ligands expression in hepatoma cells.

A New Method for Screening Natural Products to Stimulate IFN-γ Production in Jurkat Human T Lymphocytes.

Interferon-γ (IFN-γ) is a critical cytokine in the defense against viral and bacterial infection. It is mainly produced by natural killer cells and activated T cells. Given its regulatory role in coordinating cellular and humoral immune responses, IFN-γ is considered to be an effective therapeutic agent in the treatment of viral infection.

[Effects of 37 centigrade volume resuscitation on coagulation function and blood lactic acid in neonates with septic shock].

Objective: To investigate the effect of volume resuscitation with normal saline (NS) at 37 centigrade on the coagulation function and microcirculation of neonates with septic shock.

Methods: Children with septic shock admitted to neonatal intensive care unit (NICU) of the First Affiliated Hospital of Gannan Medical University were enrolled. Twenty-four newborns with septic shock were divided into two groups by random number table method (12 in each group), and were resuscitated with 10 mL/kg at 25 centigrade NS and 37 centigrade NS respectively on the basis of routine treatment.
