研究目的:

本研究拟通过临床研究比较调肠方灌肠治疗与单纯西药治疗对SP患者在胃肠功能障碍相关指标(i-FABP、D-LA、SCFA、GPR43)、安全性评价、炎性指标等方面的差异,从而了解 SP 患者在西医治疗基础上加用调肠方灌肠能够更快、更有效改善患者临床症状及炎性指标,是否立足“肺-肠”轴,从SCFA/GPR43通路干预重症肺炎合并胃肠功能障碍的一个潜在靶标,为调肠方的应用提供依据。

Objectives of Study:

This study aims to compare through clinical research the differences between Tiaochang Formula enema therapy and conventional Western medicine treatment in severe pneumonia (SP) patients regarding gastrointestinal dysfunction-related markers (i-FABPD-LA) short-chain fatty acids (SCFAs) GPCRs expressionsafety evaluationand inflammatory indicators.The study seeks to determine whether adding Tiaochang Formula enema to standard Western treatment can more rapidly and effectively improve clinical symptoms and inflammatory markers.Based on the "gut-lung axis" theory.it will investigate potential mechanisms through the SCFAs/GPCRs pathway for treating severe pneumonia complicated with gastrointestinal dysfunction.to provide scientific evidence for clinical application of Tiaochangfang.

药物成份或治疗方案详述:

对照组(西医常规组):参照《中国急诊重症肺炎临床实践专家共识》西医常规治疗。 治疗组在西医常规治疗基础上,用调肠方灌肠: 调肠方组成为:寒水石9g 滑石15g 木香6g 大黄6g 石膏45g 厚朴6g 丹皮6g 枳实9g 诃子6g。 由内蒙古自治区中医医院药剂中心提供,中药200ml保留灌肠,20分钟/次,每日一次,疗程7天

Description for medicine or protocol of treatment in detail:

Control group (conventional Western medicine group): Received standard Western medical treatment according to the "Chinese Expert Consensus on Clinical Practice for Severe Pneumonia in Emergency Medicine". Treatment group: Based on the conventional Western medicine treatment Tiaochangfang rectal infusion.

纳入标准:

肺炎诊断标准:具备下述前4项中任何1项加上第5项,并除外肺结核、肺部肿瘤、非感染性肺问质性疾病、肺水肿、肺不张、肺栓塞、肺嗜酸性粒细胞浸润症、肺血管炎等即可诊断。包括:①新近出现的咳嗽、咯痰或原有呼吸道症状加重,出现脓性痰,伴或不伴胸痛;②发热;③肺实变体征和(或)湿性哕音;④外周血白细胞计数(WBC)>10×109/L或<4×109/L,伴或不伴核左移;⑤胸部影像学检查显示新出现片状、斑片状浸润性阴影或间质性改变,伴或不伴胸腔积液。 重症肺炎诊断标准:符合下列1项主要标准或≥3项次要标准者可诊断为重症肺炎。主要标准:①气管插管需要机械通气;②感染性休克积极体液复苏后仍需要血管活性药物。次要标准:①呼吸频率R>30次;②Pa02/Fi02<250 mmHg;③多肺叶浸润;④意识障碍和(或)定向障碍;⑤血尿素氮≥7 mmol/L;⑥低血压需要积极的液体复苏。 胃肠功能障碍诊断标准 参考2012年欧洲危重病学会提出的AGI分级诊断标准,AGI II级(胃肠功能障碍):肠道缺乏完整的消化和吸收功能,无法满足机体对营养物质和水的需求,但胃肠功能障碍未影响到患者的一般状况。如胃轻瘫伴有大量胃潴留或反流、下消化道麻痹、腹泻、腹腔内高压I级(腹腔内压力12~15mmHg)、胃内容物或粪便中可见出血、食物不耐受(尝试肠内营养途径72小时未达到20 kcal/kg BW/d目标)。 西医诊断符合重症肺炎并胃肠道功能障碍的诊断标准;中医证型符合痰热腑实证:   ① 咳嗽甚则胸痛; ② 痰黄或白干黏;③ 发热,口渴; ④ 大便干结或腹胀;⑤ 舌质红或舌苔黄或黄腻,或脉数或滑数。具备 ① 、②、④ 中的 3 项,加 ③、⑤ 中的 1 项。 年龄18岁以上。患者或其授权人签署知情同意书。
