Methods： Four clinical antibiotic-resistant H. pylori strains were isolated and incubated in liquid medium containing Jinghua Weikang Capsule or Chenopodium ambrosioides L. By means of time-kill curve method, the average colony counts and bactericidal rate were calculated at time points of 0, 4, 8 and 24 h after the incubation and the time-kill curves were charted. Results： Both Jinghua Weikang Capsule and Chenopodium ambrosioides L. at a concentration of 0.64 g/L showed obvious bactericidal effect against antibiotic-resistant H. pylori after 4 h of incubation. Conclusion： Jinghua Weikang Capsule and Chenopodium ambrosioides L. are considered to be active against antibiotic-resistant H. pylori in vitro.展开更多
Objective： To study the effect of Jinguo Weikang Capsule （金果暖康胶囊, JWC） on the gene expression of H-ras, epidermal growth factor receptor （EGFR）, P53 and C-myc of the gastric mucosa in rats with gastric prec...Objective： To study the effect of Jinguo Weikang Capsule （金果暖康胶囊, JWC） on the gene expression of H-ras, epidermal growth factor receptor （EGFR）, P53 and C-myc of the gastric mucosa in rats with gastric precancerous lesions, and to investigate the action mechanism of JWC on gastric precancerous lesions. Methods： A rat model with paratypical proliferation of the gastric epithelium mucosa was established by using ^60Co irradiation. Rats were divided into the normal group, model group, high-, medium-, low-dose JWC treatment groups, and the vitacoenzyme control group, and were treated for 30 days. The expression of H-ras, EGFR, P53 and C-myc genes of the gastric mucosa was detected by using immunohistochemical methods. Results： The expression and over-expression rates of H-ras, EGFR, P53 and C-myc gene in the high- and medium-dose JWC treatment groups were significantly lower （P〈0.05） as compared with those of the model group. Conclusion： JWC can inhibit the expression of the H-ras, EGFR, P53 and C-myc genes expression of the gastric mucosa in rats, which may be one of mechanisms involved in suppressing or reversing gastric carcinogenesis.展开更多
OBJECTIVE: To investigate the inhibitory effect of Jinghua Weikang capsule(JWC) on gastric inflammation induced by Helicobacter pylori(H. pylori)via the nuclear factor-kappa B(NF-κB) signaling pathway in Kunming mice...OBJECTIVE: To investigate the inhibitory effect of Jinghua Weikang capsule(JWC) on gastric inflammation induced by Helicobacter pylori(H. pylori)via the nuclear factor-kappa B(NF-κB) signaling pathway in Kunming mice.METHODS: We investigated the anti-inflammation potential of JWC extract in vivo in a H. pylori-induced gastritis mouse model. The expression of inflammation-related molecules was evaluated by Western blotting, and the concentrations of in vivo inflammatory markers were measured by enzyme-linked immunosorbent assay. Inflammatory cell infiltration was evaluated by histopathological examination, and m RNA levels of related genes were evaluated by quantitative reverse transcription polymerase chain reaction.RESULTS: JWC had a dose-dependent protective effect against H. pylori-induced gastritis by protecting gastric epithelial cells and inhibiting inflammatory cell infiltration. Mechanistically, JWC decreased the protein levels of phosphorylated IκBαand NF-κB p65, m RNA levels of NF-κB pathway molecules, and plasma levels of tumor necrosis factor-α and interleukin 1 beta.CONCLUSION: An important finding of our study is that JWC attenuated gastrointestinal inflammation and ulceration and exerted a protective effect against gastric injury via inhibition of inflammation reactions and regulating the canonical NF-κB signaling pathway in vivo.展开更多
