文摘Chronic superficial gastritis(CSG)is a common disease of the digestive system that possesses a serious pathogenesis.Jinhong tablet(JHT),a traditional Chinese medicine(TCM)prescription,exerts therapeutic effects against CSG.However,the molecular basis of its therapeutic effect has not been clarified.Herein,we employed ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(UPLC-Q/TOF-MS)based chemical profile identification to determine the chemical components in JHT.Further,we applied network pharmacology to illustrate its molecular mechanisms.A total of 96 chemical constituents were identified in JHT,31 of which were confirmed using reference standards.Based on the bioinformatics analysis using the symptom-guided pharmacological networks of“chi,”“blood,”“pain,”and“inflammation,”and target screening through the interaction probabilities between compounds and targets,matrix metalloproteinase 2(MMP2),dopamine d2 receptor(DRD2),and Aldo-keto reductase family 1 member B1(AKR1B1)were identified as key targets in the therapeutic effect exhibited by JHT against CSG.Moreover,according to the inhibitory activities presented in the literature and binding mode analysis,the structural types of alkaloids,flavonoids,organic acids,including chlorogenic acid(10),caffeic acid(13),(-)-corydalmine(33),(-)-isocorypalmine(36),isochlorogenic acid C(38),isochlorogenic acid A(41),quercetin-3-O-a-L-rhamnoside(42),isochlorogenic acid B(47),quercetin(63),and kaempferol(70)tended to show remarkable activities against CSG.Owing to the above findings,we systematically identified the chemical components of JHT and revealed its molecular mechanisms based on the symptoms associated with CSG.
文摘目的:观察金红片联合西药对腹泻型肠易激综合征(irritable bowel syndrome-diarrhea,IBS-D)老年患者胃肠道及生活质量的影响,以探讨金红片的临床效果。方法:研究对象为80例老年IBS-D患者,选取随机数字表法将其分为两组,研究组40例和对照组40例。所有患者给予马来酸曲美布汀治疗,研究组加用金红片治疗,对照组加用藿香正气水治疗,均给予连续治疗1个月。观察两组在治疗前后胃肠道的症状、大便的频率、Bristol评分和生活质量量表(Quality of Life,QOL)评分变化情况,比较金红片与藿香正气水的临床治疗效果。结果:研究组经治疗后显效例数为28例,有效例数为10例,经治疗后总有效率达到95.0%,对照组经治疗后显效例数为14例,有效例数为16例,经治疗后总有效率为75.0%,两组比较具有显著性差异(P<0.05),提示临床诊疗效果研究组明显优于对照组。研究组经治疗胃肠道症状评分、大便频率评分、Bristol评分降低显著优于对照组(P<0.05),QOL评分升高显著优于对照组(P<0.05)。结论:金红片可明显改善老年IBS-D患者的胃肠道症状,缓解焦虑情绪,提高老年人的生活质量。
