Effect of herbal cake-partitioned moxibustion on MEK1/2 and ERK1/2 expressions of gastric tissues in rats with spleen deficiency syndrome

Objective： To observe the effect of herbal cake-partitioned moxibustion on the expressions of mitogen-activated protein kinase （MEK：1/2） and extracellular regulatory protein kinase （ERK：1/2） in gastric tissues of rats with spleen deficiency syndrome, and to explore the possible mechanisms of herbal cake-partitioned moxibustion in treating spleen deficiency syndrome. Methods： Sixty Sprague-Dawley （SD） rats were randomly divided into a blank control group （group A）, a model group （group B）, a ranitidine group （group C）, and a herbal cake-partitioned moxibustion group （group D） by random digit, 15 rats in each group. Rat models of spleen deficiency syndrome were made by intragastric administration of 4℃ 200% concentrated Da Huang （Radix et Rhizoma Rhei）. After successful modeling, the rats in group C were treated with 25 mg/（kg.bw） ranitidine by intragastric adminstration and rats in group D were treated with herbal cake-partitioned moxibustion at Zusanli （ST 36） and Zhongwan （CV 12）, for 8 d. Excepted for rats in group A, all the other rats were treated with indomethacin at 5 mg/（kg.bw） at 8：00 a.m. on the second day after finishing all the intervention and sacrificed 7 h later to isolate the stomach. Histopathological changes of the gastric tissues were observed under light microscope after hematoxylin-eosin （HE） staining. The protein expressions of MEK：1/2 and ERK：1/2 in the gastric tissues were detected by immunohistochemistry. Results： After intervention, the gastric mucosal injury in group B was significantly severer than that in group A, with large breakage and ablating; the damage of gastric mucosa was decreased in group C compared with group B; the gastric mucosal surface remained relatively complete, and the status of breakage and ablating was significantly improved. After intervention, compared with group A, the protein expressions of MEK：1/2 and ERK：12 in gastric tissues of the other groups were significantly higher （P〈0.01）. Compared with group B, the protein expressions of MEK：1/2 and ERK：1/2 in group C and D were significantly higher （all P〈0.01）. Compared with group C, the protein expressions of MEK：1/2 and ERK：1/2 in group D were significantly higher （P〈0.01）. Conclusion： Herbal cake-partitioned moxibustion promotes the repair of gastric mucosa in rats with spleen deficiency syndrome, via improving protein expressions of MEK：1/2 and ERK：1/2 in gastric tissues, as well as activating MEK/ERK signaling pathway.

Appraisal of treatment outcomes in integrative medicine using metabonomics:Taking non-alcoholic fatty liver disease with spleen deficiency syndrome as an example

Objective:Appraisal of treatment outcomes in integrative medicine is a challenge due to a gap between the concepts of Western medicine(WM)disease and traditional Chinese medicine(TCM)syndrome.This study presents an approach for the appraisal of integrative medicine that is based on targeted metabolomics.We use non-alcoholic fatty liver disease with spleen deficiency syndrome as a test case.Methods:A patient-reported outcome(PRO)scale was developed based on literature review,Delphi consensus survey,and reliability and validity test,to quantitatively evaluate spleen deficiency syndrome.Then,a metabonomic foundation for the treatment of non-alcoholic fatty liver disease with spleen deficiency syndrome was identified via a longitudinal interventional trial and targeted metabolomics.Finally,an integrated appraisal model was established by identifying metabolites that responded in the treatment of WM disease and TCM syndrome as positive outcomes and using other aspects of the metabonomic foundation as independent variables.Results:Ten symptoms and signs were included in the spleen deficiency PRO scale.The internal reliability,content validity,discriminative validity and structural validity of the scale were all qualified.Based on treatment responses to treatments for WM disease(homeostasis model assessment of insulin resistance)or TCM syndrome(spleen deficiency PRO scale score)from a previous randomized controlled trial,two cohorts comprised of 30 participants each were established for targeted metabolomics detection.Twenty-five metabolites were found to be involved in successful treatment outcomes to both WM and TCM,following quantitative comparison and multivariate analysis.Finally,the model of the integrated appraisal system was exploratively established using binary logistic regression;it included 9 core metabolites and had the prediction probability of 83.3%.Conclusion:This study presented a new and comprehensive research route for integrative appraisal of treatment outcomes for WM disease and TCM syndrome.Critical research techniques used in this research included the development of a TCM syndrome assessment tool,a longitudinal interventional trial with verified TCM treatment,identification of homogeneous metabolites,and statistical modeling.

Clinical treatment of myasthenia gravis with deficiency of spleen and kidney based on combination of disease with syndrome theory

OBJECTIVE: To study the use of Jianjining in the treatment of myasthenia gravis (MG) patients with a deficiency of both spleen and kidney via the theory on the combination of disease with syndrome. METHODS: Sixty MG patients with a deficiency of both spleen and kidney were randomly divided into an treatment group (n=30) treated with Jianjining granules and Western Medicine (prednisone or pyridostigmine bromide) and a control group (n= 30) treated with Jianjining granules. The dosage of the three drugs was reduced over the course of treatment. After 3 and 6 months of treatment, the curative effect was evaluated with the muscle weakness severity scale (MWSS). RESULTS: The MWSS score after treatment declined significantly in both groups. The score in the treatment group was much lower than that in thecontrol group (P<0.05). The total effective rate was 63.33% (19/30) in the treatment group and 36.67% (11/30) in the control group after 3 months of treatment, and 80.00% (24/30) and 50.00% (15/30), respectively, after 6 months of treatment. The obvious and total effective rates in the treatment group were much higher than those in the control group (P<0.05). After 6 months of treatment, there were no obvious differences (P>0.05) in the obvious and effective rates between the 2 groups. However, the total effective rate in the treatment group was much higher than that in the control group (P<0.01). CONCLUSION: Using the theory on the combination of disease with syndrome, we found that the curative effect of Jianjining and Western Medicine on MG patients with deficiency of both spleen and kidney is worth further exploration.

基于解痉多肽表达化生病证结合的小鼠模型探讨胃癌前病变脾胃虚实证候的本质

目的为了构建病证结合的小鼠模型及进行胃癌前病变(gastric precancerous lesions,GPL)脾胃虚实证候的本质研究。方法采用他莫昔芬(tamoxifen,TMXFR)诱导构建解痉多肽表达化生(spasmolytic peptide expression metagenesis,SPEM)小鼠模型,并在SPEM模型基础上分别模拟构建脾胃湿热证、脾气虚证模型,结合TMXFR诱导的SPEM模型具有自恢复的特性,以TMXFR组及生理盐水处理组作为对照组,监测小鼠一般情况,HE染色检测SPEM模型的构建及恢复情况,ELISA检测小鼠血清胃泌素水平,PCR检测各组小鼠胃黏膜中miR-7a-5p含量,免疫组化检测各组小鼠胃黏膜中白细胞介素-1β(interleukin-1β,IL-1β)、白细胞介素-13(interleukin-13,IL-13)表达。结果病证结合的脾胃湿热证、脾气虚证组较TMXFR组、SPEM组织恢复明显延迟;脾胃湿热证较对照组及TMXFR组的胃泌素表达异常升高(P<0.05),SPEM模型组小鼠胃黏膜中miR-7a-5p较对照组水平降低(P<0.05),病证结合的脾胃虚实组miR-7a-5p表达较TMXFR有下降趋势;病证结合的脾胃虚实组IL-1β表达较TMXFR组、对照组升高(P<0.05),脾胃湿热证、脾气虚证组中IL-13表达有升高趋。结论此项研究结果侧面证实了在癌前病灶已形成的前提下,虽无幽门螺杆菌感染,在外感湿热之邪、进食肥甘厚腻、饥饱失常、过劳伤脾等诱因下,机体可突破自身代偿修复能力,延缓SPEM恢复甚至使GPL进一步进展。这可能跟miR-7a-5p介导炎症因子IL-1β使得Th1/Th2细胞失衡相关,但具体机制尚待进一步研究。

脾虚证动物模型研究述评

中医界运用现代科学方法进行相关研究已有多年历史,在病证动物模型上颇有收获。本文对脾虚证动物模型发展历程进行回顾,对动物选择、造模方法、评价指标、消化系统病证结合模型进行总结和评论。模型动物多选用以大鼠为代表的小型啮齿类。目前,多基于病因病机造模,而较少使用化学药物与物理因素造模,复合因素造模法最常见。评价指标则分为中医证型指标、与“脾”功能和特性有关量化指标,以及方剂反证。功能性腹泻/消化不良为代表的脾虚证病证结合模型是目前研究的重心。脾虚证动物模型研究成绩斐然的同时仍存在许多不足,如缺乏脾虚证模型行业标准和共识,评价指标缺乏系统性和整体性,脾虚理论的现代阐释缺乏统一,学界亟需解决上述问题以促进发展。

目的探讨芪黄益肾汤治疗3~4期脾肾亏虚型慢性肾脏病(CKD)的临床疗效。方法选取3~4期脾肾亏虚型CKD患者82例,随机分为观察组和对照组,每组41例。两组患者均接受常规治疗,观察组加用芪黄益肾汤治疗。治疗前后比较两组患者中医证候(面色晦暗、倦怠乏力、气短懒言、食少纳呆、腰膝酸软)积分、肾功能指标[血尿素氮水平、血肌酐水平、估算肾小球滤过率(eGFR)]、血清炎症因子[血管内皮生长因子(VEGF)、转化生长因子(TGF)⁃β1、白细胞介素(IL)⁃6]水平,治疗后比较两组的临床疗效。观察治疗期间两组患者不良反应发生情况。结果治疗后,两组患者的中医证候积分降低,观察组的中医证候积分低于对照组(P<0.05);两组患者的血尿素氮、血肌酐水平降低,eGFR升高,观察组的血尿素氮水平、血肌酐水平、eGFR优于对照组(P<0.05);两组患者血清VEGF、TGF⁃β1、IL⁃6水平降低,观察组上述指标低于对照组(P<0.05);观察组总有效率高于对照组(P<0.05)。治疗期间,两组的不良反应发生率差异无统计学意义(P>0.05)。结论芪黄益肾汤可以改善3~4期脾肾亏虚型CKD患者的中医证候积分,提高临床疗效,其机制可能与下调VEGF、TGF⁃β1、IL⁃6水平有关。

1746例胃息肉中医证型与内镜特征、病理类型的相关性研究

【目的】探究胃息肉中医证型与内镜特征、病理类型的相关性。【方法】选择广州中医药大学东莞医院总院脾胃病科收治的胃息肉住院患者1746例,收集患者的各项临床资料,包括性别、年龄、中医四诊资料以及胃息肉的病理类型、好发部位、数量、大小等,分析胃息肉患者的中医证型分布规律及其与内镜特征、病理类型的相关性。【结果】(1)性别方面,1746例患者中,女性1107例(63.40%),男性639例(36.60%),男女之比为1∶1.73;年龄方面,发病率与年龄呈正相关(P<0.01),年龄越大,发病率越高,中老年人是胃息肉的好发人群,≥40岁者占比高达87.40%。(2)中医证型方面,胃息肉患者的中医证型以脾胃气虚证最多[418例(23.94%)],其他按分布频次从高到低依次为寒湿阻滞证394例(22.57%)、脾胃湿热证353例(20.22%)、气滞痰阻证311例(17.81%)和痰瘀互结证70例(15.46%)。(3)不同性别中医证型分布比较,差异有统计学意义(P<0.01),其中脾胃气虚证、寒湿阻滞证、气滞痰阻证、痰瘀互结证女性多于男性,而脾胃湿热证男性多于女性;不同年龄段中医证型分布比较,差异有统计学意义(P<0.01),其中<30岁患者多见脾胃气虚证,30~39岁和40~49岁患者多见脾胃湿热证,50~59岁患者多见气滞痰阻证,≥60岁患者多见寒湿阻滞证。(4)病理类型方面,胃息肉患者的主要病理类型为胃底腺息肉1327例(76.00%),其他依次为增生性息肉266例(15.23%)、炎性息肉146例(8.36%)、腺瘤性息肉7例(0.40%);不同病理类型中医证型分布比较,差异有统计学意义(P<0.01),其中胃底腺息肉以脾胃气虚证为主,增生性息肉以气滞痰阻证为主,炎性息肉以寒湿阻滞证为主,腺瘤性息肉以痰瘀互结证为主。(5)胃息肉数量方面,以多发性息肉为主[1120例(64.15%)],单发性息肉较少[626例(35.85%)];不同胃息肉数量的中医证型分布比较,差异有统计学意义(P<0.05),其中多发性息肉以脾胃气虚证的占比最高(25.45%),单发性息肉以脾胃湿热证的占比最高(24.28%)。(6)好发部位及大小方面,胃息肉好发于胃体、胃底等部位,直径常≤0.5 cm;但不同发病部位及胃息肉大小之间的中医证型分布比较,差异均无统计学意义(P>0.05)。【结论】胃息肉患者的中医证型与性别、年龄、病理类型和数量具有相关性;发病率与年龄呈正相关,中老年是胃息肉的好发人群;女性明显高于男性,脾胃湿热证男性多于女性,其余证型均以女性多见;胃底腺息肉以脾胃气虚证为主,增生性息肉以气滞痰阻证为主,炎性息肉以寒湿阻滞证为主,腺瘤性息肉以痰瘀互结证为主。
