BanXiaXieXin decoction treating gastritis mice with drug-resistant Helicobacter pylori and its mechanism

BACKGROUND Helicobacter pylori(H.pylori)is the main pathogen that causes a variety of upper digestive diseases.The drug resistance rate of H.pylori is increasingly higher,and the eradication rate is increasingly lower.The antimicrobial resistance of H.pylori is an urgent global problem.It has been confirmed that Banxia Xiexin decoction(BXXXT)demonstrates the effects of treating gastrointestinal diseases,inhibiting H.pylori and protecting gastric mucosa.The purpose of the present study is to further explore the therapeutic effects of BXXXT on drug-resistant H.pylori.AIM To confirm that BXXXT demonstrates therapeutical effects in vivo and in vitro on gastritis mice with drug-resistant H.pylori and explain its mechanism to provide an experimental basis for promoting the application of BXXXT.METHODS The aqueous extract of BXXXT was gained by water decocting method.The inhibitory effect of the aqueous extract on H.pylori was detected by dilution in vitro;drug-resistant H.pylori cells were used to build an acute gastritis model in vivo.Thereafter,the model mice were treated with the aqueous extract of BXXXT.The amount of H.pylori colonization,the repair of gastric mucosal damage,changes of inflammatory factors,apoptosis,etc.,were assessed.In terms of mechanism exploration,the main medicinal compositions of BXXXT aqueous extract and the synergistic bacteriostatic effects they had demonstrated were analyzed using mass spectrometry;the immune function of peripheral blood cells such as CD3+T and CD4+T of mice with gastritis before and after treatment with BXXXT aqueous extract was detected using a flow cytometry;the H.pylori transcriptome and proteome after treatment with BXXXT aqueous extract were detected.Differently expressed genes were screened and verification was performed thereon with knockout expression.RESULTS The minimum inhibitory concentration of BXXXT aqueous extract against H.pylori was 256-512μg/mL.A dose of 28 mg/kg BXXXT aqueous extract treatment produced better therapeutical effects than the standard triple therapy did;the BXXXT aqueous extract have at least 11 ingredients inhibiting H.pylori,including berberine,quercetin,baicalin,luteolin,gallic acid,rosmarinic acid,aloe emodin,etc.,of which berberine,aloe emodin,luteolin and gallic acid have a synergistic effect;BXXXT aqueous extract was found to stimulate the expressions of CD3+T and CD4+T and increase the number of CD4+T/CD8+T in gastritis mice;the detection of transcriptome and proteome,quantitative polymerase chain reaction,Western blotting and knockout verification revealed that the main targets of BXXXT aqueous extract are CFAs related to urea enzymes,and CagA,VacA,etc.CONCLUSION BXXXT aqueous extract could demonstrate good therapeutic effects on drug-resistance H.pylori in vitro and in vivo and its mechanism comes down to the synergistic or additional antibacterial effects of berberine,emodin and luteolin,the main components of the extract;the extract could activate the immune function and enhance bactericidal effects;BXXXT aqueous extract,with main targets of BXXXT aqueous extract related to urease,virulence factors,etc.,could reduce the urease and virulence of H.pylori,weaken its colonization,and reduce its inflammatory damage to the gastric mucosa.

姜制半夏传统制作工艺考证

姜半夏传统制作工艺:完整半夏姜制法多在前期生半夏汤洗的基础上进行,亦有直接用姜汤洗的记载。半夏片为汤洗后切片,再用姜汁浸、炒、煮、蒸等,以炒法为优。半夏粉为半夏汤洗切片研细粉,再用姜汤浸澄,多用于制作糊丸或包衣。半夏饼为汤洗后半夏研粉与生姜汁或去皮生姜混合制成的饼状物,再经炙、煨、炒等法而成。半夏曲始于宋代,当时半夏曲有制饼与发酵两种,均以生姜为辅料。制饼者并没有发酵的过程,实为半夏饼。半夏曲的配方众多,生姜必不可少。地方炮制经验中将生半夏水浸泡,生姜煮取汁,再共同煮制为主流。地方炮制规范中多为生半夏水浸透,姜汤矾水共煮。现代学者的研究方向主要集中在炮制工艺优选与炮制原理两方面。建议恢复姜半夏的传统汤洗姜制工艺。
