Anti-inflammatory Effect of Wumen Zhike Gancao Decoction on Rats with Lumbar Disc Herniation Associated with Lipid Metabolic Disorder

[Objectives] To study the anti-inflammatory effect of Wumen Zhike Gancao Decoction (ZKGC) on rats with lumbar disc herniation (LDH) associated with lipid metabolic disorder.[Methods] A rat model of LDH was established by implantation of the autologous nucleus pulposus from the coccygeal vertebra of each rat tail, and histopathology, immunohistochemistry and biochemistry assays were employed to evaluate the treatment effects of ZKGC. In addition, the metabolic characteristics of LDH and ZKGC treatment were investigated with a liquid-chromatography with time-of-flight mass spectrometer (LC/Q-TOF-MS)-based metabolomics study. Nucleus pulpous tissues from rat models were collected and analyzed by metabolomics.[Results] By metabolism network analysis, lipid metabolism was up-regulated in LDH rat models and the treatment with ZKGC significantly reversed the abnormal up-regulated lipid metabolism. Meanwhile, the treatment of ZKGC also regulated the markers of neuron autophagy and inflammatory response in serum.[Conclusions] These results indicated that a complex mechanism, including abnormal lipid metabolism, associates with the progress of LDH, and multiple pathways might be involved in ZKGC s therapeutic effects on LDH.

Proteomic analysis of a chronic obstructive pulmonary disease mouse model to determine the efficacy of treatment using Guben Zhike decoction

Background:Guben Zhike decoction(GBZKD)is derived from the experience of Professor Enxiang Chao,an esteemed master of Chinese medicine,while treating chronic obstructive pulmonary disease(COPD).GBZKD reinforces the healthy qi and consolidates defensive qi.This study explored the efficacy and potential mechanism of action of GBZKD in a COPD mouse model using proteomics.Methods:A COPD mouse model was established through cigarette smoke exposure and intranasal lipopolysaccharide administration.The model was verified through lung function test and lung histopathological observation.Label-free quantitative proteomics was used to detect the lung tissue proteins of mice from the GBZKD,COPD,and control groups.Results:GBZKD markedly improved the lung function and associated pathological conditions in the COPD mouse model.Proteomic analysis identified 4316 proteins,of which 3696 were quantitative proteins.We highlighted 287 and 184 proteins with significant regulatory roles in the lung tissues of COPD mice and GBZKD-treated mice,respectively.These proteins participated in multiple functions,including complement/coagulation cascade,immune response,and metabolic pathways.Conclusion:GBZKD exhibits multitarget and multipathway therapeutic effects in a COPD mouse model.

Long-term Toxicity of Maxing Erchen Zhike Granules

[Objectives]To study the long-term toxicity of Maxing Erchen Zhike granules to rats after intragastric administration,so as to provide reference for its preclinical safety evaluation.[Methods]Total 80 rats were randomly and evenly divided into high-dose group(1.2 mL/100 g,120 g/kg),middle-dose group(96.0 g/kg),low-dose group(72.0 g/kg)and blank control group.The rats in the treatment groups were administered with corresponding doses of Maxing Erchen Zhike granules,and those in the blank control group were given with equal-amount normal saline.The administration lasted for 30 consecutive days.During the experiment,the rats'feed intake,activity,feces and other conditions and toxicity reactions were observed every day.After 24 h of the last administration,12 rats(half male and half female)were randomly selected from each group.Each of the rats was anesthetized with 10%chloral hydrate solution(0.3 mL/100 g)through intraperitoneal injection and subjected to abdominal aorta blood collection(two tubes)for hematological examination and blood biochemical examination(serum).Then,the main organs of the rats were weighed,and pathological examinations were performed.After that,the main organs were weighed and pathological examination was performed.The remaining rats in each group were discontinued and observed for 14 d.On the 15th d,they were subjected to the same treatment,and the body weight,organ coefficients,hematological indices,blood biochemical indices and pathological indices were examined.[Results]After 30 d of administration,there was no abnormality in the appearance and behavior of the animals.There was no significant difference in the daily consumption of feed among the groups,and there was no special case of weight gain.Among the blood biochemical indices,the ALB and ALT levels of each administration group were significantly different from those of the blank control group(P<0.05).The results of histopathological examination show that there was one case of interstitial pneumonia in each of the high-dose group,middle-dose group and blank control group.After 14 d that the administration was stopped,one case of focal myocarditis appeared in the high-dose group,and one case of interstitial pneumonia appeared in the middle-dose group.[Conclusions]Maxing Erchen Zhike granules are safe to be administered to rats at 100 times the clinical dose.and there should be no safety hazards clinically when used at conventional doses.

目的研究宣肺化湿止咳汤治疗咳嗽变异性哮喘的临床效果及对呼出气一氧化氮(FeNO)数值的影响。方法选择2018年7月—2019年12月收治的120例咳嗽变异性哮喘患者作为研究对象,40例采用沙美特罗替卡松粉(舒利迭)吸入治疗作为西药组,40例采用宣肺化湿止咳汤治疗作为中药组,最后40例采用二者联合治疗作为联合组。观察三组治疗效果、咳嗽症状积分、FeNO水平、咳嗽生活质量以及不良反应情况。结果联合组的治疗总有效率为97.5%(39/40),明显高于西药组的80.0%(32/40)、中药组的82.5%(33/40),差异有统计学意义(P<0.05);治疗后联合组FeNO水平低于西药组和中药组,莱切斯特咳嗽问卷(LCQ)评分高于西药组和中药组,日间积分与夜间积分均低于西药组和中药组,差异均有统计学意义(P<0.05);西药组和中药组FeNO水平、LCQ评分、日间积分与夜间积分对比,差异无统计学意义(P>0.05)。结论宣肺化湿止咳汤联合西药治疗咳嗽变异性哮喘,效果较好,能明显减轻患者临床症状,提高生活质量,降低炎症反应,值得临床应用及推广。

基于cAMP/PKA/CREB信号通路探讨固本止咳方治疗慢性阻塞性肺疾病稳定期小鼠的作用机制

目的基于环磷酸腺苷(cAMP)/蛋白激酶A(PKA)/cAMP反应元件结合蛋白(CREB)信号通路探讨固本止咳方(GBZK)治疗慢性阻塞性肺疾病(COPD)稳定期小鼠的作用机制。方法60只BALB/c小鼠随机分为对照组、模型组、GBZK组、地塞米松组,除对照组外,其余组均使用烟草烟雾暴露联合脂多糖复制COPD稳定期小鼠模型。造模成功后,GBZK组予GBZK 0.2 mL/d灌胃,地塞米松组予1.0 mg/kg地塞米松注射液腹腔注射,2次/d,所有小鼠均给药28 d。观察各组小鼠一般情况,酶联免疫吸附测定法(ELISA)检测小鼠肺组织匀浆cAMP水平,利用Western blot检测小鼠肺组织匀浆中cAMP、p-PKA、CREB、p-CREB蛋白表达情况。结果与模型组比较,GBZK组小鼠的喘息气促有所改善,肺组织匀浆中cAMP含量及cAMP、p-PKA、CREB、p-CREB蛋白表达均提高(P<0.05)。结论固本止咳方可能通过激活cAMP/PKA/CREB信号通路,进而发挥对COPD稳定期小鼠的保护作用。
