Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic and progressive fibrosing inter-stitial pneumonia. Till now, it is lack of effective and safe treatment. In recent years, more and more clinical trials of traditional Chinese medicine (TCM) have been conducted with different evaluation criteria and indexes. The knowl-edge is disunity and unsystematic. From the perspective of combination of disease and TCM syndrome model, this ar-ticle summarized and organized the current data and medical standards, and then come up with the new evaluation system of clinical effect and describe important indexes and methods. This article was aimed to improve the clinical trial design and provide high quality evidences for evidence-based medicine.

This study was aimed to discuss the anti-inflammatory and immunization properties ofRe-Du-Ning (RDN) injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with phlegm-heat stagnated in the lung syndrome. A total of 110 in-patients were collected from January 2012 to December 2013. Cases were randomly divided into the treatment group (basic treatment plan + 20 ml RDN injection + 250 mL of 5% GS injection, once a day, intravenous injection) and the control group (basic treatment plan + 20 ml of 0.9% NS injection + 250 mL of 5% GS injection, once a day, intravenous injection), with 55 cases in each group. The treatment course was 14 days. Observations were made on traditional Chinese medicine (TCM) symptom score, clinical effect, blood routine examination, blood gas analysis and T lymphocyte subgroups before and after the treatment in both groups. The results showed that in the aspects of TCM symptom score and clinical effect, the posttreatment TCM symptom score and total integration in the treatment group were obviously improved compared to the control group except for shortness of breath, dry mouth and thirsty, flushing (P < 0.05). The total effective rate was obviously better than that of the control group. In the aspect of anti-inflammation, the total white blood cell (WBC) count and the normal neutrophil percentage of both pretreatment and posttreatment in the treatment group were obviously decreased compared to pretreatment (P < 0.05). However, there were no statistical differences on WBC count and normal neutrophil percentage compared to posttreatment in the control group. In the aspect of blood gas analysis, the posttreatment PaCO2 and PaO2 of the treatment group were obviously better than the control group (P < 0.05). In the aspect of immune regulation, the posttreatment T lymphocyte subgroups CD3+ and CD4+ of the treatment group were higher than the control group. The expression inhibition / cytotoxic lymphocyte (CD8+) was obviously lower than the control group (P < 0.05). The CD4+ / CD8+ was back to the normal reference level. It was concluded that in the treatment of AECOPD with phlegm-heat stagnated in the lung syndrome, on the basis of western medicine symptomatic treatment plan, RDN injection was assisted to clear heat, relieve toxin and remove phlegm. It can obviously improve patient’s clinical symptoms and increase the clinical therapeutic effects. The treatment was especially targeted to infection-induced respiratory failure patients combined low immunity with possible identified therapeutic effects.

Idiopathic pulmonary fibrosis(IPF)is a progressive and inflammatory interstitial lung disease,clinically divided into stable and acute exacerbation periods of idiopathic pulmonary fibrosis(AE-IPF),which faces great difficulties in prevention and treatment,increasing the health and life burden of patients.At present,the diagnostic methods of AE-IPF are relatively limited,while biomarkers are safe,simple and specific,which are of great significance for the diagnosis and treatment of AE-IPF.Based on the theoretical connotation of AE-IPF(lung heat and collateral obstruction syndrome),this paper explores the application value of combining AE-IPF lung heat stagnation syndrome and biomarkers,explains the pathogenesis of AE-IPF lung heat stagnation syndrome at the molecular level,and analyzes the guiding role of combining syndromes and biomarkers in the clinical application of traditional Chinese medicine for AE-IPF lung heat stagnation syndrome.

Bitter taste is one of the important contents in the theory of"Five tastes"in traditional Chinese medicine(TCM).It has the functions of"releasing,dryness and firmness"and plays an important role in the treatment of respiratory diseases.Bitter taste receptors(T2Rs)is a kind of G-protein-coupled receptors,studies have shown that it can act on human airway smooth muscle,relax smooth muscle and dilate bronchus,and play a vital role in the treatment of bronchial asthma and chronic obstructive pulmonary disease.It can also inhibit the inflammatory reaction and reduce the damage of lung tissue by reducing the release of inflammatory factors and promoting the apoptosis of inflammatory cells.The therapeutic mechanism of bitter Chinese herbs action may depend on the effect of T2Rs,the effects of bitter Chinese herbs such as"lowering qi","releasing heat","eliminating dampness"are quite consistent with the cognitions of western medicine that bitter taste receptors could"relaxe bronchus","reduce airway resistance","inhibits inflammatory factors"and"reduces mucus secretion".Based on the understanding of bitter taste in TCM theory and modern research,this study aims to discuss the effect of bitter Chinese herbs depend on T2Rs as the starting point,so as to provide a new research direction for clinical treatment of pulmonary diseases such as bronchial asthma and chronic obstructive pulmonary disease.

In the past decades,numerous chemical analysis studies have identified numerous compounds in tobacco smoke,and the number is increasing,as of 2013,9582 compounds have been identified in tobacco smoke,including nicotine,tobacco smoke-specific nitrosamines,benzo[alpha]pyrene and other substances,as well as cotinine,4-(methylnitrosamine)-1-(3-pyridyl)-1-butanol and other products that are metabolized in the body.The products of metabolic transformation,such as cotinine and 4-(methylnitrosamine)-1-(3-pyridyl)-1-butanol,can target the heart,lungs and other organs,inducing chronic obstructive pulmonary disease,coronary heart disease,lung cancer,esophageal cancer and other types of cancer.Chinese medicine's understanding of"toxicity"originates from the Nei Jing,which believes that"poisonous evil"can be an external pathogenic factor,but can also cause the five organs to lose harmony and produce phlegm and stagnation and other pathological products that accumulate into internal toxicity.The modern medical understanding of tobacco smoke toxic substances and their metabolites is quite consistent with the understanding of"external toxicity"and"internal toxicity"in Chinese medicine,so the author intends to explore the main components and pathogenic mechanisms of tobacco smoke harmful substances and their metabolites.To clarify the etiological characteristics and pathogenic transformation characteristics of"internal"and"external"tobacco smoke toxicity,so as to explore the modernization of"tobacco smoke toxicity"and the combination of tobacco smoke pathogenesis and TCM theory for TCM.Theoretical foundation is laid.

Animal experiment is a key link in the scientific research of traditional Chinese medicine,and the syndrome animal model is an important research object in the animal experiment of traditional Chinese medicine.Good reproducibility,repeatability,specificity,safety,convenience and economy are the basic requirements of animal model.In recent years,with the continuous development of animal experimental studies on lung diseases,the animal model construction and evaluation methods of related syndromes have been improved to a certain extent.However,in terms of model evaluation,problems such as more subjective descriptions,less accurate quantification,more macro representations,less microscopic evidence,more disease-related indicators,less syndrome-related indicators,and lack of primary and secondary stratification of indicators continue to be prominent.Therefore,based on the literature review method,the author systematically reviewed the current research progress of lung disease syndrome models,and proposed that strengthening the research on the four-diagnosis manifestations and reaction characteristics of model animals,standardization of modeling interventions,four-diagnosis information collection tool and the objective evaluation study,and the TCM syndrome model evaluation scale study might be feasible approaches for future model optimization.In order to provide new ideas and methods for the study of the syndrome model of lung disease in the future.

The aging disease associated with type 2 diabetes mellitus(T2DM)is a hot research topic in the field of diabetes at present.Sarcopenia has become the third major complication of T2DM after microvascular and macrovascular diseases,which could lead to the occurrence and development of various adverse events such as fracture,disability,and dysfunction.The spleen belongs to the earth,is in the middle jiao,governs transportation and transformation,and governs muscle.The functional activities of the spleen manifesting in normal transformation and transportation,the distribution of cereal essence,and the nourishment of muscles are necessary for normal physiological functions to be exerted.Recent studies have shown that skeletal muscle cell ferroptosis plays an important role in the pathogenesis of T2DM sarcopenia.Based on the theory of"spleen governing transportation and transportation and governing muscle",this study explores the pathogenesis of T2DM sarcopenia from the perspectives of the pathogenesis of"dysfunction of spleen in transportation,deficiency of cereal essence,obstruction of dampness and turbidity,and muscle dystrophy"in traditional Chinese medicine and the pathological mechanism of"skeletal muscle cell ferroptosis"in modern medicine.It summarizes the principles of traditional Chinese medicine prevention and treatment for T2DM sarcopenia based on the spleen,to provide theoretical support for enriching the theoretical connotation of spleen visceral state,as well as basic research and clinical trials on the prevention and treatment of T2DM sarcopenia with traditional Chinese medicine.

Type 2 Diabetes Mellitus(T2DM)is a chronic metabolic disease characterized by disorders of insulin and glucose.As a disease closely related to our daily diet,the molecular mechanism of its pathogenesis is still unclear.Sweet taste receptors are a kind of G protein-coupled receptors with 7 times transmembrane.Although the research on the pathogenesis of T2DM has been gradually deepened,there are few studies on the mechanism of sweet taste damage in the state of disease.Therefore,in-depth study of the pathological mechanism of T2DM sweet taste receptor damage is of great significance to further understand the molecular characteristics of sweet taste receptors and explore new targets of traditional Chinese medicine in the treatment of T2DM.In this paper,the biological characteristics of sweet taste receptors,signal transduction mechanism of sweet taste receptors,sweet taste receptors and T2DM,sweet taste receptors and"spleen is sweet"are reviewed in order to provide the latest opinions for the targeted prevention and treatment of this kind of diseases by traditional Chinese medicine and the elucidation of related pathological mechanism.

Objective To explore the biological basis of different diseases with the same syndrome for pulmonary related comorbidities(pulmonary hypertension,obstructive sleep apnea syndrome,chronic obstructive pulmonary disease,lung cancer)in idiopathic pulmonary fibrosis(IPF)through genomic bioinformatics analysis.Methods GSE110147,GSE113439,GSE135917,GSE106986 and GSE118370 datasets were downloaded as research subjects.The differential genes between each disease group and the control group were screened.Cytoscape 3.10.0 software was used for topology analysis to screen core genes.OmicShare was used to perform GO and KEGG pathway enrichment analyses on core genes.Results A total of 23 core genes related to IPF was obtained.GO enrichment analysis showed that core genes were mainly enriched in biological processes such as cellular process,metabolic process,biological regulation/biological process,developmental process,localization,response to stimulus,immune system process and signaling;in cellular components such as cellular anatomical entity and protein-containing complex;in molecular functions such as binding,catalytic activity,structural molecule activity,molecular adaptor activity,molecular function regulator and transcription regulator activity.KEGG pathway enrichment analysis showed that core genes were mainly enriched in ribosome biogenesis in eukaryotes,AGE-RAGE signaling pathway in diabetic complications,Th17 cell differentiation,JAK-STAT signaling pathway,RNA polymerase,neutrophil extracellular trap formation.Conclusion Using genomic bioinformatics analysis to explore the core genes and signaling pathways of pulmonary related comorbidities in IPF can reveal the mechanism of different diseases with the same syndrome for pulmonary related comorbidities in IPF to a certain extent.

Chronic obstructive pulmonary disease （COPD）， as a chronic respiratory disease that can be prevented and intervened but cannot be completely cured， has increasing incidence and mortality rates year by year， often complicated by one or more comorbidities. However， there is currently no specific treatment available. Therefore， the healthcare issues related to COPD are urgent and prominent. Traditional Chinese medicine （TCM） delays the progression of COPD through multiple mechanisms， pathways， and targets. As a result， exploring the pathogenesis of COPD and identifying TCM treatment approaches and effective prescriptions are key issues that urgently need to be addressed in clinical practice. In TCM， COPD is categorized into syndromes such as "cough"， "asthma"， and "lung distension". It is believed that the deficiency in the origin runs through the entire disease. When external pathogens invade， Qi becomes disordered， and phlegm and blood stasis begin to accumulate， leading to an excess condition in the manifestation. Modern medicine research on the pathogenesis of COPD mainly involves aspects such as inflammatory response， oxidative stress， autophagy imbalance， and aging. Studies have found that Chinese medicine monomers， single herbs， and compound prescriptions can improve COPD by inhibiting inflammation， reducing oxidative damage， correcting autophagy， and delaying aging. However， there is no study that intuitively organizes the various pathogenesis mechanisms of COPD and their interrelationships. At the same time， research on the therapeutic effects of TCM on COPD primarily focuses on exploring a single mechanism or pathway， without integrating multiple mechanisms， pathways， and targets. Additionally， there are very few studies that summarize the corresponding relationships between the various pathogenesis mechanisms of COPD and the regulatory effects and signaling pathways of Chinese medicine. This study， for the first time， combines the latest literature in China and abroad to explain the various pathogenesis mechanisms of COPD and their interrelationships using a combination of graphs， text， and tables. It also outlines the signaling pathways， targets， and mechanisms of Chinese medicine monomers， single herbs， and compound prescriptions in regulating COPD， in order to provide new ideas and strategies for the in-depth research and systematic treatment of COPD with TCM.
