An investigation into the HIF-dependent intestinal barrier protective mechanism of Qingchang Wenzhong decoction in ulcerative colitis management.

Ethnopharmacological Relevance: Ulcerative colitis (UC) is a chronic, non-specific inflammatory disease affecting the colon and rectum with an etiology that remains elusive. Traditional Chinese medicine (TCM) has been widely used on long-term UC treatment to better maintain the efficacy than traditional aminosalicylic acid or glucocorticosteroids and to ease financial burden of patients. Qingchang Wenzhong Decoction (QCWZD) is a modern TCM decoction with established clinical efficacy but the mechanism of its protection on intestinal barrier function remains unclear.

[Effect of superfine powder and aqueous extract of Polygonati Rhizoma on rats with natural perimenopausal syndrome].

This study aims to examine the effect of superfine powder and aqueous extract of Polygonati Rhizomaon on natural perimenopausal syndrome in rats and explore the underlying mechanism. To be specific, a total of 60 female SD rats(14-15 months old) with estrous cycle disorder were screened by the vaginal smear and randomized into model control group, β-estradiol 3-benzoate group(0.1 mg·kg~(-1)), superfine powder of Polygonati Rhizoma group(0.

Effects of ultrafine powder on sub-health mice induced by unhealthy lifestyle based on neuroendocrine immune system.

Sub-health status, in which a person's mind and body exist in a low-quality state of being between disease and health, has become an urgent public health problem that cannot be ignored globally. One of the most apparent sub-health symptoms is fatigue, and it also shows a significant decrease in mental vitality and adaptability caused by disruption of the neuroendocrine-immune system. (DOF) has a long history of use in China as a medicinal food with immune-regulating, anti-fatigue, anti-oxidant, and hypoglycemic effects.

Total alkaloid fraction of Leonurus japonicus Houtt. Promotes angiogenesis and wound healing through SRC/MEK/ERK signaling pathway.

Ethnopharmacological Relevance: Leonurus japonicus Houtt., also known as motherwort, is a traditional Chinese medicine that was first identified in Shennong Bencao Jing, the first and essential pharmacy monograph in China. L.

Two Novel Phenylpropanoid Trimers From Hort With Inhibitory Activities on Alpha-Hemolysin Secreted by .

The emergence of antibiotic resistance in has necessitated the development of innovative anti-infective agents acting on novel targets. Alpha-hemolysin (Hla), a key virulence factor of , is known to cause various cell damage and death. In this study, with bioassay-guided fractionation, a pair of unusual epimeric lignan trimers, ligustchuanes A and B ( and ), were isolated from the rhizomes of Hort, together with two known phthalides being identified by UPLC-QTOF-MS.

The anti-infective activity of against by attenuating accessory gene regulator system-mediated virulence.

Due to the rapid evolution of antibiotic resistance in , antivirulence therapy may be a promising alternative for the effective control of the spread of resistant pathogens. The Chinese Materia Medica has been widely used for the treatment of diseases and production of health foods, and it remains a valuable resource for the discovery of compounds possessing antivirulence activity. Through a infection model, an EtOAc-soluble fraction of 80% EtOH extract of Bunge (SMEA) was found to possess potential anti-infective activity against .

Evaluation of the Activity and Efficacy of Anidulafungin-Loaded Human Serum Albumin Nanoparticles Against .

Recent decades have seen a significant increase in invasive fungal infections, resulting in unacceptably high mortality rates. Anidulafungin (AN) is the newest echinocandin and appears to have several advantages over existing antifungals. However, its poor water solubility and burdensome route of administration (i.

Homocysteinylation and Sulfhydration in Diseases.

Homocysteine (Hcy) is an important intermediate in methionine metabolism and generation of one-carbon units, and its dysfunction is associated with many pathological states. Although Hcy is a non-protein amino acid, many studies have demonstrated protein-related homocysteine metabolism and possible mechanisms underlying homocysteinylation. Homocysteinylated proteins lose their original biological function and have a negative effect on the various disease phenotypes.

Chondroitin Sulfate Alleviates Diabetic Osteoporosis and Repairs Bone Microstructure Anti-Oxidation, Anti-Inflammation, and Regulating Bone Metabolism.

Diabetic osteoporosis (DOP) belongs to secondary osteoporosis caused by diabetes; it has the characteristics of high morbidity and high disability. In the present study, we constructed a type 1 diabetic rat model and administered chondroitin sulfate (200 mg/kg) for 10 weeks to observe the preventive effect of chondroitin sulfate on the bone loss of diabetic rats. The results showed that chondroitin sulfate can reduce blood glucose and relieve symptoms of diabetic rats; in addition, it can significantly increase the bone mineral density, improve bone microstructure, and reduce bone marrow adipocyte number in diabetic rats; after 10 weeks of chondroitin sulfate administration, the SOD activity level was upregulated, as well as CAT levels, indicating that chondroitin sulfate can alleviate oxidative stress in diabetic rats.

[Protective effects of Dendrobium officinale superfine powder against LPS-induced intestinal mucosal injury in mice].

This study aims to investigate the preventive effect of Dendrobium officinale in LPS-induced intestinal mucosal damage. Forty SPF-grade C57 BL/6 J male mice were randomly divided into normal group(NC), model group(LPS), and two superfine powder groups of Dendrobium officinale(DOF)(DOF-L, 0.30 g·kg~(-1)and DOF-H, 0.

Luteolin ameliorates lipopolysaccharide-induced microcirculatory disturbance through inhibiting leukocyte adhesion in rat mesenteric venules.

Background: Microcirculatory disturbance is closely associated with multiple diseases such as ischemic and septic stroke. Luteolin (3,4,5,7-tetrahydroxyflavone) is a vascular protective flavonoid present in several dietary foods. However, how luteolin plays a role in microcirculatory disturbance is still unknown.

Preventing from subverting host plasminogen for invasive infection treatment.

is a common fungal pathogen in humans that colonizes the skin and mucosal surfaces of the majority healthy individuals. How disseminates into the bloodstream and causes life-threatening systemic infections in immunocompromised patients remains unclear. Plasminogen system activation can degrade a variety of structural proteins and is involved in several homeostatic processes.

Hydrogen sulfide attenuates postoperative cognitive dysfunction through promoting the pathway of Warburg effect-synaptic plasticity in hippocampus.

Postoperative cognitive dysfunction (POCD) is deemed to a severe surgical complication without effective treatment. Previous work has confirmed the important modulatory role of hydrogen sulfide (HS) in cognitive function. This study was proposed to explore whether HS relieves POCD and the possible mechanisms.

TLR3 inhibitor and tyrosine kinase inhibitor attenuate cigarette smoke/poly I:C-induced airway inflammation and remodeling by the EGFR/TLR3/MAPK signaling pathway.

Tobacco smoke is the major risk factor for developing chronic obstructive pulmonary disease (COPD). Viral infection is a major cause of COPD exacerbation, which lacks effective drug treatments. In the present study, to mimic the pathogenesis of COPD, we employed a TLR3 ligand [Poly (I:C), PIC] to mimic viral infection to determine whether it enhances the effects of cigarette smoke (CS)-induced airway inflammation and remodeling.

Dectin-1 Facilitates IL-18 Production for the Generation of Protective Antibodies Against .

Invasive candidiasis (IC) is one of the leading causes of death among immunocompromised patients. Because of limited effective therapy treatment options, prevention of IC through vaccine is an appealing strategy. However, how to induce the generation of direct candidacidal antibodies in host remains unclear.
