Ethnopharmacological Relevance: Schisandra chinensis is used as a traditional Chinese medicine to treat a variety of diseases. Schisandra chinensis lignans (SCL) are one of the most active components extracted from Schisandrae chinensis fructus, exhibit a broad array of pharmacological properties, especially anti-inflammatory and hepatic lipid-lowering effects, suggesting SCL may have potential anti-nonalcoholic steatohepatitis (NASH) ability. However, the therapeutic efficacy of SCL against NASH and the underlying mechanism of this action remains unclear.

Background: Chronic bronchitis (CB), a type of chronic obstructive pulmonary disease (COPD), poses a significant global health burden owing to its high morbidity and mortality rates. Eucalyptol, limonene and pinene enteric capsules (ELPs) are clinically used as expectorants to treat various respiratory diseases, including CB, but their acting mechanisms remain unclear. In this study, we investigated the anti-CB effects of ELP in a rat model of lipopolysaccharide (LPS)-induced CB.

Spinal muscular atrophy (SMA) is a type of autosomal recessive genetic disease, which seriously threatens the health and lives of children and adolescents. We attempted to find some genes and mutations related to the onset of SMA. Eighty-three whole-blood samples were collected from 28 core families, including 28 probands with clinically suspected SMA (20 SMA patients, 5 non-SMA children, and 3 patients with unknown etiology) and their parents.

Aim: To investigate whether electroacupuncture ST36 activates enteric glial cells, and alleviates gut inflammation and barrier dysfunction following hemorrhagic shock.

Methods: Sprague-Dawley rats were subjected to approximately 45% total blood loss and randomly divided into seven groups: (1) sham: cannulation, but no hemorrhage; (2) subjected to hemorrhagic shock (HS); (3) electroacupuncture (EA) ST36 after hemorrhage; (4) vagotomy (VGX)/EA: VGX before hemorrhage, then EA ST36; (5) VGX: VGX before hemorrhage; (6) α-bungarotoxin (BGT)/EA: intraperitoneal injection of α-BGT before hemorrhage, then EA ST36; and (7) α-BGT group: α-BGT injection before hemorrhage. Morphological changes in enteric glial cells (EGCs) were observed by immunofluorescence, and glial fibrillary acidic protein (GFAP; a protein marker of enteric glial activation) was evaluated using reverse transcriptase polymerase chain reaction and western blot analysis.

Aim: The aim of this study was to investigate the effect of electroacupuncture at ST36 (EA ST36) on gastric emptying and mucosal blood flow during intragastric resuscitation with pyruvate-enriched oral rehydration solution (Pyr-ORS) in scalded rats.

Methods: The rats were subjected to a 35% total body surface area (TBSA) of scald injury and randomly divided into five groups (N=24) and two subgroups (n=12) in each group. The Pyr-ORS was delivered intragastrically according to the Parkland formula immediately after scalding at a dose of 1 mL kg(-1) %TBSA(-1) in 1 h.

Objective: To investigate the significance of changes in plasma high mobility group box-1 protein (HMGB1) levels and its relationship with sepsis and endotojemia in severely burned patients.

Methods: Totally 25 large area burned patients ( > 30% total body surface area) were included in this study, and 8 healthy volunteers served as normal controls. The plasma levels of HMGB1 were measured by ELISA, and endotoxin concentrations was determined by the modified chromogenic limulus amebocyte lysate (LAL) assay on posthurn days 1, 3, 5, 7, 14, 21, and 28.

Aim: To explore the expression of avian reticuloendotheliosis viral(v-rel) oncogene-related B (RelB) mRNA in vitro in murine mature and immature myeloid dendritic cells (DCs).

Methods: The bone marrow was collected from the femur and tibias of C57BL/6 mice in sterile condition. Bone marrow precursors were cultured with recombinant mouse granulocyte-macrophage colony-stimulating factor (rmGM-CSF) and interleukin-4 (rmIL-4) to produce immature DCs.

Objective: To establish a simple and economic method for in vitro culture of tolerogenic dendritic cells (Tol-DC) from mouse bone marrow to facilitate further research of the application of Tol-DC in autoimmune disease.

Methods: The dendritic cells were derived from in vitro culture of the precursor cells from mouse bone marrow with recombinant mouse granulocyte-macrophage colony-stimulating factor (rmGM-CSF) and interleukin (IL)-4, respectively. Eighteen hours before completion of cell culture, lipopolysaccharide (LPS) was added in the medium for stimulating rmGM-CSF-treated cells, but not IL-4-treated cells.
