The Efficacy of Liposomal Bupivacaine in Thoracic Surgery: A Systematic Review and Meta-Analysis.

Purpose: Patients undergoing thoracic surgery suffer from severe postoperative pain, and a series of complications will occur if there is no effective analgesic treatment. Liposomal bupivacaine (LB) is a novel multivesicular formulation with up to 72 hours of analgesia, which can be used in thoracic surgery. This meta-analysis aimed to evaluate the efficacy of LB in improving recovery in patients undergoing thoracic surgery compared with non-liposomal local anesthetics.

Bioinformatics analysis revealed underlying molecular mechanisms associated with asthma severity and identified GABAergic related pathway as a potential therapy for Th2-high endotype asthma.

Background: Asthma, a principally T helper 2 (Th2) cell mediated immunological disease, is categorized into Th2-high and Th2-low endotypes. The influence of these endotypes on clinical characteristics and treatment responsiveness in asthma is yet to be completely understood. This study delves into the underlying molecular mechanisms of Th2 endotypes on asthma.

Electroacupuncture-induced activation of GABAergic system alleviates airway inflammation in asthma model by suppressing TLR4/MyD88/NF-κB signaling pathway.

Background: Electroacupuncture (EA) has been shown to attenuate airway inflammation in asthmatic mice; however, the underlying mechanism is not fully understood. Studies have shown that EA can significantly increase the inhibitory neurotransmitter γ-aminobutyric acid (GABA) content in mice, and can also increase the expression level of GABA type A receptor (GABAAR). Furthermore, activating GABAAR may relieve inflammation in asthma by suppressing toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-kappa B (NF-κB) signaling pathway.

Toll-like receptor 4 signaling pathway in sensory neurons mediates remifentanil-induced postoperative hyperalgesia via transient receptor potential ankyrin 1.

Remifentanil-induced postoperative hyperalgesia (RIH) refers to a state of hyperalgesia or aggravated pre-existing pain after remifentanil exposure. There has been considerable interest in understanding and preventing RIH. However, the mechanisms responsible for RIH are still not completely understood.

Effects of colloid preload on the incidence of hypotension in spinal anesthesia for cesarean section: a systematic review and meta-analysis.

Background: Hypotension is a common complication caused by spinal anesthesia (SA), which may have adverse impacts on the condition of the parturient and fetus. Liquid infusion was found to be relatively effective for reducing the incidence of hypotension. However, the question of whether colloid preload can optimize hemodynamic variables in the cesarean section remains controversial.

Risk of True Allergy to Local Anesthetics: 10-Year Experience from an Anesthesia Allergy Clinic in China.

Background: Local anesthetics (LAs) have been widely used throughout the healthcare settings, especially in local anesthesia and pain management. The incidence of allergic reactions to LAs remains uncertain. The danger of allergic reactions to the use of LAs in every day of clinical practice is a matter of great concern.

A monomer purified from Paris polyphylla (PP-22) triggers S and G2/M phase arrest and apoptosis in human tongue squamous cell carcinoma SCC-15 by activating the p38/cdc25/cdc2 and caspase 8/caspase 3 pathways.

Recent studies have shown that the aqueous, ethanolic extracts and a monomer compound of Paris polyphylla exhibit anticancer activity toward several types of cancer cell lines, but the anticancer activity of (3β,17α,25R)-spirost-5-ene-3,17-diol 3-O-α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranoside, a monomer isolated from P. polyphylla (PP), named PP-22, has not been reported previously. In this study, we investigated the effect of PP-22 on human tongue squamous cell carcinoma SCC-15 cells in vitro.
