Shenqi Fuzheng Injection (SFI) a well-known traditional Chinese medicine (TCM) formula, has been extensively used as an adjuvant to chemotherapy for cancer treatment in clinic. However, the chemical constituents in SFI, especially water-soluble ingredients, had not been investigated so far. In this study, an ultra-fast liquid chromatography (UFLC) coupled(More)
There is a need of in vivo COPD models for mucus hypersecretion study. The current study compared three rat models induced by cigarette smoke (CS) exposure alone or combined with pre- or post-treatment with lipopolysaccharide (LPS). Forty rats were randomly divided into the four following groups: control group, LPS + CS group (CS exposure for 4-wk combined(More)
ETHNOPHARMACOLOGICAL RELEVANCE Radix Codonopsis and Radix Astragali, of which Shenqi Fuzheng Injection (SFI) is composed, are commonly used in traditional Chinese medicine to improve immune function against chronic diseases. AIM OF THE STUDY The present study was thus designed to systematically elucidate the in vivo immuno-enhancement effects of SFI in(More)
Naringin has been reported as an effective anti-inflammatory compound. We previously showed that naringin had antitussive effect on experimentally induced cough in guinea pigs. However, the effects and mechanism of naringin on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice are not fully understood. In this study, our aim was to evaluate(More)
The present study evaluates protective effects of naringin against paraquat (PQ)-induced acute lung injury (ALI) and pulmonary fibrosis in mice. Survival probability against PQ intoxication was tested by a single intraperitoneal injection of PQ. Results showed that survival rates of mice exposed to PQ only (50 mg/kg within 7 days) were much lower than that(More)
SCOPE Resveratrol, a powerful natural compound for human health, is widely reported for its immunity-related beneficial properties. However, few works have studied its effect mechanism on immunity. The present study was conducted to investigate the effects of resveratrol on splenic immunity in restraint stressed mice and the mechanism was further studied as(More)
Naringin is a flavonoid that exists in many plants and traditional Chinese medicines. In this study, a highly sensitive and specific electrospray ionization (ESI) liquid chromatography-tandem mass spectrometry (LC/MS/MS) method was developed for quantification of naringin and its two metabolites, naringenin and naringenin glucuronide. Naringin and(More)
Naringenin, the aglycone of naringin, has been reported to attenuate MUC5AC secretion by inhibiting activity of nuclear factor kappa B (NF-κB) via EGFR-PI3K-Akt/ERK MAPKinase signaling pathways. However, previous studies demonstrated that the MUC5AC promoter was located in two different regions: an activator protein-1 (AP-1) binding site and a NF-κB binding(More)
Naringin has been reported to act as an effective anti-inflammatory compound. In a previous study, we demonstrated that the anti-inflammatory effect of naringin on lipopolysaccharide (LPS)-induced acute lung injury in mice correlated with the inhibition of the nuclear factor-κB (NF-κB) pathway. However, the effects(More)
Target identification of the known bioactive compounds and novel synthetic analogs is a very important research field in medicinal chemistry, biochemistry, and pharmacology. It is also a challenging and costly step towards chemical biology and phenotypic screening. In silico identification of potential biological targets for chemical compounds offers an(More)
