A Novel Apprehension of the Primary Lung Meridian, Sinew Channel, Divergent Channel, Luo-Connecting Channel Acting as a Single Unit System to Serve Respiration Function Based on Modern Neurophysiology and Kinesiology

The TCM philosophy of a meridian and associated channels pertains to the specific function of one or more organs. We define the Lung Primary Meridian (LUM) together with the Lung Sinew (LUSC), Divergent (LUDC), Luo-connecting (LULCC) Channels as a system of routes plus some parts of the body (such as muscles) to fulfil respiration, as a main function under different situations. There is very limited information about the Lung associated channels in classical literature of TCM. With a clear focus on the function of respiration, we have carried out a detailed analysis of the biomedical consequence of stimulating the LUM, analysed the roles played by LUSC, LUDC, and LULCC. The updated LUM and LUDC include acupoints of other meridians, serving the same purpose of performing satisfactory respiration starting from checking the quality of the inflow through the nose. The LUSC includes the respiratory muscles (plus the associated connective tissues) extending to various parts of the body. The muscles of the limb (as part of the LUSC) embrace the nerves that provide routes for somatosensory reflexes and play the role of locomotion, providing voluntary respiration via the pectoralis muscles. The muscles of LUSC are bounded by stiff connective tissue layers, forming compartments, and are part of the pulley system for various body locomotions. Within a compartment, the interstitial fluid, blood, lymph flows must be potent to protect the associated nerves related to LUM;the healthy state of the LUSC also provides freedom of various types of locomotion. The LULCC exists because the vagus nerve has a part of it passing through the spinal cords all the way down to the sacrum domain, with exiting nerve innervating two-third of the large intestine. The crucial steps of our deductions are supported by experimental evidence based on modern neurophysiology and kinesiology. We discover that all the four channels stated above work as a unit system to allow respiration to be possible under various postures/conditions. The complexity of structures and processes is eased off by providing 29 figures and 13 tables for the relevant muscles and nerves. In addition to respiration, the Lung system in TCM context includes interaction of this system with the sweat gland and neuroendocrine system;such aspects will be left to another study.

Experimental Study on the Mechanism of Protective Effect of Free Fu on Gut-derived Endotoxin-Mediated Lung Damage

The effect of tumor necrosis factor-α (TNF-α) on endotoxin (ET)-mediated lung damage caused by incomplete ligation of large intestine and the influence of free Fu on the expression of TNF-α mRNA were explored. Forty SD rats were randomly divided into 4 groups: normal control group, model group, ligation group and treatment group (n=10 in each group). The models were made by the method of partly ligating the rectum outside the body. The plasma level of lipopolysaccaride was measured by dynamic nephelo metric method and the serum level of TNF-α was detected by the method of radioactive immunity. The expression of TNF-α mRNA in lung tissue was detected by RT-PCR method. The results were compared among the 4 groups. The results showed the plasma levels of ET and serum TNF-α in the model group and the expression of TNF-α mRNA in the lung tissues were remarkably higher than those in the normal control group (P<0.01). After the treatment of free Fu, all of the above indexes in the treatment group were all decreased as compared with model group (all P<0.01), and the damage to lung was alleviated. It was concluded that TNF-α might play a very important role in the ET-mediated lung damage caused by incomplete ligation of large intestine, free Fu could protect the lung from damage.

The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang on the concentration of trace elements in the main organs of COPD rats

Objective:To test two theories from traditional Chinese medicine:'exterior -interior relationship between the lung and large intestine' and 'treating from the intestine principle for lung disorders'.The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang (XBCQT) on the concentration of three trace elements-copper (Cu),zinc (Zn),and manganese (Mn)-was observed in the tissues of the lung,small intestine,large intestine,and stomach of rats suffering from chronic obstructive pulmonary disease (COPD).Methods:Thirty-five male Wistar rats were divided randomly and equally into five groups:control;model;Fei treatment (A);Chang treatment (B);and Fei-Chang treatment (C).A rat model of COPD was prepared by tracheal injection of lipopolysaccharide plus exposure to cigarette smoke.Treatments with medicinal herbs started day-22 of administration and exposure to cigarette smoke for 7 days.The control group and model group were administered physiologic (0.9%) saline solution via the stomach.After 7 days of intervention,the tissues of the lung,small intestine,large intestine,and stomach were removed.Inductively coupled plasma-atomic emission spectroscopy was used to detect the levels of Cu,Zn,and Mn in those tissues.Results:Compared with the control group,the Cu concentration in the tissues of the small intestine,large intestine,and stomach increased significantly in the model group (P <.05);the Mn concentration in the tissues of the lung,large intestine,and stomach increased significantly in the model group (P <.05);the Zn concentration in the tissues of the lung and large intestine decreased significantly in the model group (P <.05).In comparison of the model group:the Cu concentration in the tissues of the lung and large intestine decreased significantly in the B group (P <.05);the Mn concentration in the tissues of the lung,small intestine,and large intestine decreased significantly in the B group (P <.05);the Zn concentration in the tissues of the lung,small intestine,and large intestine increased significantly in the B group (P <.05).For the A group versus C group comparison,the Zn concentration in the tissues of the small intestine and stomach increased significantly in the latter (P <.05).Conclusion:This study showed that 'treating from the intestine' using Xuan Bai Cheng Qi Tang and its modified formulae can regulate the concentration of trace elements in the main organs of COPD rats.This may be one of the mechanisms for intestine-based treatment for COPD.

The Association between Pulmonary Function Impairment and Colon Inflammation in Ulcerative Colitis Patients： A Scientific Basis for Exterior-Interior Correlation between Lung and Large Intestine

Objective： To investigate the involvement of pulmonary function impairment in ulcerative colitis（UC）, and explore a scientific basis for the Chinese medicine（CM） theory of exterior-interior correlation between Lung（Fei） and Large intestine（Dachang）. Methods： Totally 120 patients with a diagnosis of UC were recruited and the demographics, clinical data, and blood samples were collected. C-reactive protein（CRP） and erythrocyte sedimentation rate（ESR） concentrations were measured. Every patient accepted pulmonary function test and took chest radiograph（CXR）. Results： Pulmonary function abnormalities were present in 72 of 120 patients. The median（interquartile range） vital capacity（VC）, forced vital capacity（FVC）, forced expiratory volume in 1 s（FEV_1）, carbon monoxide diffusion capacity（DL_∞） of lung, total lung capacity（TLC） and functional residual volume（FRV） were decreased in distal UC and pancolitis compared with ulcerative prochitis（P〈0.0005）. Male patients had increased VC, FEV_1/FVC, and residual volume（RV）/TLC compared with female（P〈0.0005）, but decreased DLCO and carbon monoxide iffusion capacity（KCO） of lung/alveolar ventilation（P〈0.0005）. Age was strongly correlated with RV（Spearman rank correlation coefficient（rs）=–0.57, P〈0.0001）, and RV/TLC（rs=0.48, P〈0.0001）. Age was also correlated with FEV_1/FVC（rs=–0.29, P=0.001）, forced expiratory flow in 75% vital capacity（FEF75%, rs=–0.20, P=0.03）, DLCO（rs=–0.21, P=0.02）, TLC（rs=–0.25, P=0.006）, and FRV（rs=–0.28, P=0.002）. The course of disease was correlated with FEF75%（rs=–0.18, P=0.049） and KCO（rs=–0.19, P=0.036）. Chest radiograph abnormalities were presented in 38 of 120. Pulmonary symptoms were presented in 10 of 120. Other extraintestinal complications were presented in 21 of 120. Conclusions： Pulmonary function impairment was more frequently than other extraintestinal complications in UC patients, which may be affected by sex, age, extent and course of disease. These results may be a scientific basis for the theory of exterior-interior correlation between Lung and Large intestine.

Infrared Thermal Imaging-Based Research on the Intermediate Structures of the Lung and Large Intestine Exterior-Interior Relationship in Asthma Patients

Objective: By observing body surface temperature variation of the intermediate structures of the Lung(Fei) and Large Intestine(Dachang) exterior-interior relationship in asthmatic patients, to investigate the pathological response on the pathway of channels and to substantiate the objective existence of the intermediary structures. Methods: The study included 60 subjects meeting the bronchial asthma inclusion criteria(experimental group) and 60 healthy subjects(normal control group). ATIR-M301 infrared thermal imaging device was used for detecting body surface temperature of the subjects and collecting the infrared thermal images. The temperature values of the intermediate structures of Lung and Large Intestine exterior-interior relationship [throat, Quepen, elbow, nose, Lieque(LU 7), Pianli(LI 6)], control areas(0.2 cm lateral to the above structures) and Yintang(EX-HN 3) were measured on the infrared thermal image by infrared imaging system. Then, the above temperature values were compared and analyzed within and between two groups. Results: There were insignificant differences between the temperature on the left and right sides of the intermediate structures(Quepen, elbow, LU 7, LI 6) in normal control group(P>0.05). Except for that of Quepen, there were insignificant differences between the temperature of the intermediate structures and their corresponding control areas in normal control group(P>0.05). In the experimental group, the temperature on the left and right sides of the intermediate structures(Quepen, elbow, LU 7, LI 6) showed statistically significant differences(P<0.05 or P<0.01); the temperature difference between intermediate structure(throat, Quepen, elbow, nose, LI 6) and their respective control areas were also significant(P<0.05 or P<0.01). The temperature of the intermediate structures(throat, Quepen, elbow, LU7, LI 6) between the experimental group and normal control group showed significant differences(P<0.05 or P<0.01). Conclusions: This study is an initial step to validate the objective existence of Lung and Large Intestine exterior-interior relationship intermediate structures, as described in the Chinese classical medical literatures, through the functional imaging angle. The intermediate structures are the pathological reaction areas of the bronchial asthmatic patients.

Understanding the viscera-related theory that the lung and large intestine are exterior-interiorly related

Pairing of the viscera and bowels is an important theory,which provides guidance to traditional Chinese medicine(TCM) clinical practice.Investigating this theory has been the focus of research on the basic theory of TCM.Recently,researchers have performed many studies on the theory that the lung and large intestine are exterior-interiorly related,which is a different point of view to that of previous literature,recent clinical studies and experimental studies,and these recent studies have enforced the theoretical connotation of the statement.However,there are problems in some of these studies including recent clinical studies and experimental studies.In the current article,literature on the viscera-related theory of the lung and large intestine are exterior-interiorly related is reviewed from physiological,pathological,and clinical views,and some opinions on the current research status are discussed.

从“金郁泄之”论治溃疡性结肠炎

“金郁泄之”理论出自《黄帝内经》,“金”是肺与肠的基本属性,“郁”指郁滞,壅塞不通的异常状态,故“金郁”可理解为属金脏腑如肺、大肠所发壅滞、阻塞之证。“泄之”是五行属金脏腑郁滞的治疗方法,其具体含义应随“金郁”的病理产物、病位的不同而不同。溃疡性结肠炎多由邪蕴肠腑,气血瘀滞,肠道传导失司,湿、热、瘀于大肠相互搏结成郁,改变肠道属金肃降之性所致,其核心病机为湿热内蕴,气血瘀滞,属于“金郁”的范畴,病位虽在大肠,可波及于肺。故治疗应顺应“泄之”的法则,以祛除肺肠之郁为主,包括清泄与宣泄两种方法,同时补益肺、脾、肾三脏之气,以恢复肺肠之功能,达到扶正祛邪,标本兼顾的目的,促进溃疡性结肠炎的愈合。

A Comparative Study of The Regular Pattern of Syndrome and Treatment of Lung-intestine Related Diseases in Ancient and Modern Medical Cases Based on Data Mining

Objective: To analyze the similarities and differences of the applications of "the lung and large intestine being interior-exteriorly related"between the ancient and modern clinical practices, and to reveal the theory meaning.Method: Based on the ancient and modern medical cases database, 245 ancient medical records and 373 modern medical records were studied with the general statistical description and analysis of association rules, and the results were compared to summarize the similarities and differences of the regular pattern of syndrome and treatment on lung-large intestine related diseases in ancient and modern medical records.Results: In modern medical cases, intestinal diseases appeared with the main symptom of constipation due to deficiency of lung qi and qi stagnation of large intestine were always treated by purgation together with replenishing and restoring lung qi. In ancient medical cases, large intestine heat was always caused by lung heat and a variety of diarrhea symptoms appeared. They were always treated by clearing heat and moistening lungs. In addition, the symptom of bound stool caused by qi stagnation of large intestine due to lung qi stagnation was always treated by lowering lung qi to regulate and smooth large intestine qi. And Armeniae Amarum Semen was used by both as a core medicinal herb.Conclusion: Ascending-descending of qi movement is the core of the lung and large intestine relationship. In other words, the lung and the large intestine communicate through qi.

基于“肺与大肠相表里”理论和“整体观念”探讨慢性肺系病合并功能性便秘的诊治思路

慢性肺系病和功能性便秘均是临床常见的难治性疾病,且易合并出现。对二者分别进行干预是现代医学的常规治疗模式,但疗效及安全性均不能令人满意。课题组在临床实践中发现,中医药治疗慢性肺系病合并功能性便秘具有独特的优势。笔者在中医“肺与大肠相表里”理论和“整体观念”指导下,提出慢性肺系疾病合并功能性便秘的病机涉及肺失宣肃致腑气不通、大肠传导失司致肺气上逆、脾失健运、肾精亏损、气血两虚、久病瘀滞等方面,治疗当以“肺肠合治”为总则,辅以健脾益肾、补气养血以扶本虚,行气化瘀以祛实邪,并据此整理临床常用方药,系统总结了本病的中医诊治思路。

从肠论治脓毒症所致ALI/ARDS有效性的Meta分析

目的系统评价在中医“肺与大肠相表里”理论下指导下,从肠论治脓毒症所致急性肺损伤/急性呼吸迫综合征(ALI/ARDS)的临床疗效,为临床提供循证参考。方法通过计算机检索中国知网(CNKI)、万方数据库、维普中文期刊数据库、中国生物医学文献数据库(CBMdisc)荷兰医学文摘Embase数据库、美国国立医学图书馆PubMed数据库、Cochrane图书馆数据库中,从建库至2020年10月8日发表的将通腑法作为干预措施治疗脓毒症所致ALI/ARDS的随机对照试验(RCT)。对照组采用常规西医治疗,试验组在常规西医治疗基础上联合通腑法治疗。由2名研究者筛选文献并对符合纳入标准的文献进行数据提取,运用改良Jadad量表进行质量评价,采用RevMan5.4和Stata16.0软件对数据进行Meta分析。结果最终纳入13篇文献,均为单中心RCT,其中≥4分的文献7篇,<4分的文献6篇。共纳入579例患者,其中试验组290例,对照组289例。Meta分析显示,与对照组比较,联合通腑法治疗能明显提高脓毒症所致ALI/ARDS患者氧合指数[PaO_(2)/FiO_(2),均数差(MD)=62.55,95%可信区间(95%CI)为55.74~69.37,P<0.05],降低白细胞介素-6(IL-6,MD=-29.70,95%CI为-48.34~-11.06,P<0.05)、肿瘤坏死因子-α(TNF-α,MD=-2.94,95%CI为-5.28~-0.59,P<0.05)降钙素原(PCT,MD=-1.34,95%CI为-2.17~-0.51,P<0.05)和C-反应蛋白(CRP,MD=-22.41,95%CI为-36.52~-8.29,P<0.05)水平,缩短机械通气时间(MD=-2.26,95%CI为-2.86~-1.66,P<0.05)和重症监护病房(ICU)住院时间(MD=-4.15,95%CI为-7.47~-0.84,P<0.05),降低28d病死率[相对危险度(RR)=0.43,95%CI为0.24~0.76,P<0.05]和急性生理学与慢性健康状况评分Ⅱ(APACHEⅡ,MD=-3.53,95%CI为-5.41~-1.64,P<0.05)。结论从肠论治对减轻脓毒症所致ALI/ARDS患者病情及改善预后有一定价值,但仍需进一步开展高质量的RCT以验证其疗效,为临床治疗提供更准确的循证医学证据。

从“肺-肠”轴角度探讨肠道菌群与过敏性鼻炎的关系

过敏性鼻炎属于全球高发的气道变应性疾病,较多人群深受其影响,关于其更安全有效的治疗方式仍不断被探寻与挖掘。近年来关于肠道微生态与肺部疾病的相互关系被深入研究,文章基于肺肠关系,结合中医“肺与大肠相表里”理论,并从西医胚胎发育、菌群微环境、内分泌代谢、黏膜免疫等角度探讨肺-肠关系,在此基础上,认为肠道菌群可从细胞因子免疫平衡、机体黏膜等方面影响过敏性鼻炎的发生发展,以期为临床治疗过敏性鼻炎提供更多思路。

基于“肺与大肠相表里”综述中药干预肺系疾病对肺、肠组织炎性因子及菌群变化

肺是维系呼吸道健康的重要门户,各种原因如感染细菌或病毒、接触过敏原、吸烟、遗传因素等均可引起肺部疾病,引发不同程度的炎症反应。呼吸道感染可伴随不同程度的肠道症状,即“肺病及肠”,故“肺与大肠相表里”这一中医理论在临床对此类症状疾病的治疗中应用广泛,且疗效显著。文章通过对近年来相关文献的研究,试从肺、肠道组织炎症因子、菌群变化等角度出发,综述中医药治疗肺系疾病的作用机制及疗效,以期为日后的研究开展新方向。

基于烟草对癌变的影响探讨肺与大肠相表里

目的 通过分析烟草对人体各部位癌症发病率的影响,探讨肺肠轴理论与“肺与大肠相表里”的中医理论的关系。方法 收集从2017年—2021年来院就诊的137591人中的2477例肿瘤患者的一般信息、吸烟史、肿瘤原发部位等,对收集的资料进行肿瘤发病率统计分析和比较。结果 吸烟可提高消化系统癌症的病发率,仅次于呼吸道并远高于其他部位的癌症病发率。这一现象符合“肺与大肠相表里”的中医理论和现代医学中肺肠轴学说。结论 肺系疾病易引发肠道疾病,而肠道疾病也易引发肺系疾病,此现象可用中医“肺与大肠相表里”解释,肺-肠轴理论可作为“肺与大肠相表里”理论的翻译。

中医学对肠道菌群与非酒精性脂肪性肝病的理论认识

近年来,非酒精性脂肪性肝病全球流行率逐年升高,但发病机制至今尚未明确。中医学将非酒精性脂肪性肝病归属于“臌胀”“肝癖”“痰浊”“积聚”等,认为肝体用失调、脾肾亏虚是本病主要特点,痰、湿、浊、瘀、热为本病主要病理因素。随着对肠道菌群研究的不断深入,肠道菌群及其代谢产物有改善胰岛素抵抗、减少氧化应激、调节脂质代谢和调节免疫等多种作用,与肝脏功能及非酒精性脂肪性肝病之间的关系也受到广泛关注。许多研究揭示了肠-肝轴与非酒精性脂肪性肝病发生发展相关,饮食、抗生素、益生菌及益生元、粪菌移植、微生态制剂、噬菌体等干预措施均可以通过改变肠道菌群来缓解非酒精性脂肪性肝病。从现代医学对肠道菌群生理功能的研究中,我们发现现代医学“肠”的消化吸收、调节代谢、改善免疫等功能可属于中医“脾主运化”“脾主升清”功能的范畴。文章从中医“肝脾相关”“肝与大肠相通”“肝从左升,肺从右降,肺与大肠相表里”等理论视角出发,就中医学对肠道菌群与非酒精性脂肪性肝病关系的认识及相关治疗作一综述,阐述中医学治疗本病的理论基础,结合现代医学理念,以期为非酒精性脂肪性肝病的中医治疗提供新思路、新方法。

基于“肺与大肠相表里”理论探讨肠屏障损伤与慢性阻塞性肺疾病的关系

在中西医不同的理论里,肺与大肠均存在密切的联系,在西医的理论里,肺与大肠在分化发育、生理病理、功能协作、物质联系上有结构、功能、菌群基础作为支撑依据,而这种联系与中医经典《黄帝内经》中所讲“肺与大肠相表里”不谋而合,在中医的“肺与大肠相表里”理论里肺与大肠通过经脉相络属,生理相协调以达到相互联系的目的,在汗牛充栋的历代医案中,也不乏肺病从肠论治,肠病从肺论治的治疗策略,现代医学研究发现,肠屏障的损伤与慢性阻塞性肺疾病之间可相互影响彼此的疾病病理发展进程,其中微生物屏障(主要为肠道菌群)可能是将肺与大肠进行动态联系的重要活性基础,其调节方式主要通过肠道菌群代谢产物实现,如维生素、短链脂肪酸等,因此维持肠道菌群的动态平衡及修复受损的肠屏障可能成为慢性阻塞性肺疾病的一种潜在治疗策略。文章通过系统归纳总结梳理了目前国内外学者对于肺与大肠在肠屏障损伤与慢性阻塞性肺疾病之间的潜在联系及最新的研究进展,综述了有关于肺与大肠在分化发育、生理病理、功能协作及物质联系之间的相互关系,阐释肠屏障损伤与慢性阻塞性肺疾病之间相互影响的联系,以期对该理论有进一步的认识并为临床上对肺肠疾病的治疗提供新思路。
