With the progression of CKD, the risk of cardiovascular death increases, which is associated with the elevated levels of uremic toxins （UTs）. Representative toxins such as indoxyl sulfate and p-cresyl sulfate are involed in CKD progression and cardiovascular events inseparable from the key role of endothelial dysfunction. The therapeutic strategies of UTs are aimed at signaling pathways that target the levels and damage of toxins in modem medicine. There is a certain relevance between toxins and ＂turbid toxin＂ in the theory of Chinese medicine （CM）. CM treatments have been demonstrated to reduce the damage of gut-derived toxins to the heart, kidney and blood vessels. Modern medicine still lacks evidence-based therapies, so it is necessary to explore the treatments of CM.展开更多

The infection is generally acquired in childhood, but can persist into adulthood. Eradication therapy has undergone several modifications. The aim of this study was to evaluate the different therapeutic strategies used in the eradication of Helicobacter pylori infection in the Centre Hospitalier Universitaire La Reference Nationale of N’Djaména. Patients and Methods: This was a prospective, descriptive analytical study spread over one year, from September 2021 to September 2022. Patients at least 15 years of age presenting with dyspeptic symptoms, seen consecutively in a hepato-gastroenterology consultation and with a positive stool test for H. pylori infection, were included in the study. Equally, 1/3 of patients were treated with dual or triple therapy. The remaining third received quadritherapy. Results: A total of 268 patients were included in the study (mean age 38.40 ± 14.66 with extremes of 16 and 80 years). Males predominated in 58% of cases. Overall therapeutic efficacy was 88.9%. According to different therapeutic strategies, efficacy was 90.75% for dual therapy with PPI (Rabeprazole) and Amoxicillin. On the other hand, efficacy was 87% and 88.88% for PPI-based triple therapy and dual antibiotic therapy, and for PPI-based quadruple therapy and triple antibiotic therapy. Conclusion: H. pylori infection is a common disease in Chad. Dual therapy with rabeprazole combined with a high dose of amoxicillin over a period of at least two weeks showed similar if not better efficacy than triple or quadruple therapy.展开更多

文摘目的研究24 h咽喉反流事件发生的时间点分布特征。方法回顾性分析2013年1月至2020年3月在解放军总医院第六医学中心耳鼻咽喉头颈外科医学部就诊的408例患者[男339例,女69例,年龄23~84(55.08±11.08)岁]的24 h腔内多通道阻抗pH监测(24 h MII-pH)数据,分析气体酸/弱酸反流、气液混合酸/弱酸反流、液体酸/弱酸反流和碱反流事件在不同时间点的发生次数,采用SPSS 26.0软件进行统计学分析。结果基于24 h MII-pH,咽喉反流(LPR)阳性率为77.45%(316/408),气体弱酸反流阳性率显著高于其他类型的反流事件(χ^(2)=297.12,P<0.001)。除气体弱酸反流以外,其余类型反流事件的发生率均呈现餐后升高的趋势,尤其在晚餐后更明显。液体酸反流事件主要发生在晚餐后到次日晨起期间,其中47.11%(57/121)发生在晚餐后3 h内。反流症状量表评分与气体弱酸反流(r=0.127,P<0.01)、液体酸反流(r=0.205,P<0.01)和液体弱酸反流(r=0.103,P<0.05)事件之间有显著正相关关系。结论除气体弱酸反流以外,其余类型反流事件的发生率均呈现餐后升高的趋势,尤其在晚餐后更明显。气体弱酸反流在反流事件中的占比最大,其致病机制还需要进一步探索。
