RESUMEN
The present study explored the regularity of prescriptions for the treatment of intermediate and advanced lung cancer to provide references for clinical medication. CNKI, Wanfang, VIP, and CBM were searched for the research papers on the treatment of lung cancer by Chinese medicine published from database inception to May 31, 2021. The relevant information of qualified papers was extracted to establish a database. The Chinese medicines with frequency >3% underwent analysis of the latent structure and association rules by Lantern 5.0 and SPSS Molder 14.1, respectively, and the prescription regularity in the treatment of intermediate and advanced lung cancer was analyzed based on the frequency description. A total of 713 papers were included, involving 327 Chinese medicines with a cumulative frequency of 12 794 and 106 prescriptions with a cumulative frequency of 824. The commonly used Chinese medicines were dominated by deficiency-tonifying, heat-clearing, phlegm-resolving, and cough/dyspnea-relieving drugs, such as Astragali Radix, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Ophiopogonis Radix, Poria, and Hedyotis Diffusa, which are cold, warm, and plain in nature and sweet, bitter, and pungent in flavor, and mainly act on lung, spleen, and stomach meridians. Commonly used prescriptions included Shashen Maidong Decoction, Liujunzi Decoction, and Baihe Gujin Decoction. The latent structure analysis revealed 32 latent variables and 65 hidden classes. Six comprehensive clustering models and 11 core prescriptions were obtained by professional knowledge inference. The common syndromes of intermediate and advanced lung cancer were inferred to be Qi and Yin deficiency in the lung, Qi deficiency in the lung and spleen, Yin deficiency in the liver and kidney, combined phlegm and stasis, phlegm-heat obstructing lung, and Qi stagnation and blood stasis. Forty-four strong associations were screened out by association rules analysis, including four pairwise strong associations(Polygonati Odorati Rhizoma→Ophiopogonis Radix, Polygonati Odorati Rhizoma→Glehniae Radix, Amomi Fructus→Atractylodis Macrocephalae Rhizoma, and Polygonati Rhizoma→Astragali Radix) and 40 triplet strong associations(such as Trichosanthis Radix+Glehniae Radix→Ophiopogonis Radix, Polygonati Odorati Rhizoma+Glehniae Radix→Ophiopogonis Radix, Trichosanthis Radix+Ophiopogonis Radix→Glehniae Radix, and Scutellariae Barbatae Herba+Codonopsis Radix→Hedyotis Diffusa). In the treatment of intermediate and advanced lung cancer, Qi-replenishing and Yin-nourishing drugs are mainly employed, assisted with cancer-resisting, toxin-removing, spleen-invigorating, phlegm/stasis-resolving, and blood-activating drugs based on syndrome differentiation. The roots were treated following the principles of tonifying lungs and replenishing the spleen, and symptoms following the principles of removing the toxin, dispelling stasis, and resolving phlegm.

Objective:To explore the syndrome distribution of cough cases in ancient Chinese medical books. Method:A total of 9 323 cough cases in the database of lung diseases in ancient Chinese medical books were extracted. Lantern 5.0 was used to construct the latent structure model for the 100 manifest variables based on the first 50 symptoms and 50 Chinese herbal medicines, and different latent nodes were interpreted. The syndrome differentiation patterns of syndromes with symptoms and Chinese herbal medicine (formula) were quantitatively revealed by the comprehensive clustering weights of latent structure. The correlation of diseases with syndromes was fitted through the binary Logistic regression analysis. Result:There were 204 syndromes involved in 9 323 cough cases with 18 syndromes showing a frequency higher than 100. As demonstrated by the model established on the first 50 symptoms and 50 Chinese herbal medicines, 35 latent variables, 98 latent classes, and 10 comprehensive clustering models were obtained, where <italic>Z</italic>5<italic> </italic>was the highest in the threshold value (6.7), <italic>Z</italic>6 in the information coverage of productive cough (52%), and <italic>Z</italic>7 in the score (19). The binary Logistic regression model fitted the correlation between different disease types and five syndromes, where the dominance ratio of external wind to the syndrome of wind-heat invading lung reaching up to 88.919, those of syndrome of phlegm-heat accumulating in lung to diseased heat and sputum 51.594 and 15.861, and those of the syndrome of phlegm-dampness obstructing lung to dampness, phlegm, and fluid retention 31.415, 34.370, and 4.936, respectively. Conclusion:The newly discovered cough syndromes included lung heat and yin deficiency, external cold and internal fluid retention, weakness of spleen and stomach, and phlegm and blood stasis in lung. In most cases, multiple syndromes were observed clinically, such as syndrome of deficiency of both Qi and Yin in lung combined with yin deficiency in lung and kidney. Since differentiation of traditional Chinese medicine (TCM) syndrome is subjective, the weight can indicate the difference in the contributions of different symptoms to the syndrome, which is of guiding significance for syndrome inference. The latent structure model combined with Logistic regression analysis can solve the problem of quantification in TCM syndrome differentiation and can be used to explore the syndrome distribution of diseases.

OBJECTIVE@#Critical effective constituents were identified from Bufei Yishen formula (BYF), a traditional herbal compound and combined as effective-constituent compatibility (ECC) of BYF I, which may have potential bioactive equivalence to BYF.@*METHODS@#The active constituents of BYF were identified using four cellular models and categorised into Groups 1 (Bufeiqi), 2 (Bushen), 3 (Huatan) and 4 (Huoxue) according to Chinese medicinal theory. An orthogonal design and a combination method were used to determine the optimal ratios of effective constituents in each group and the ratios of "Groups 1 to 4" according to their pharmacological activity. We also comprehensively assessed bioactive equivalence between the BYF and the ECC of BYF I in a rat model of chronic obstructive pulmonary disease (COPD).@*RESULTS@#We identified 12 active constituents in BYF. The numbers of constituents in Groups 1 to 4 were 3, 2, 5 and 2, respectively. We identified the optimal ratios of effective constituents within each group. In Group 1, total ginsenosides:Astragalus polysaccharide:astragaloside IV ratio was 9:5:2. In Group 2, icariin:schisandrin B ratio was 100:12.5. In Group 3, nobiletin:hesperidin:peimine:peiminine:kaempferol ratio was 4:30:6.25:0:0. In Group 4, paeoniflorin:paeonol ratio was 4:1. An orthogonal design was then used to establish the optimal ratios of Group 1, Group 2, Group 3 and Group 4 in ECC of BYF I. The ratio for total ginsenosides:Astragalus polysaccharide:astragaloside IV:icariin:schisandrin B:nobiletin:hesperidin:peimine:paeoniflorin:paeonol was determined to be 22.5:12.5:5:100:12.5:4:30:6.25:25:6.25. A comprehensive evaluation confirmed that ECC of BYF I presented with bioactive equivalence to the original BYF.@*CONCLUSION@#Based on the ECC of traditional Chinese medicine formula method, the effective constituents of BYF were identified and combined in a fixed ratio as ECC of BYF I that was as effective as BYF itself in treating rats with COPD.
RESUMEN
Objective:To explore cough cases recorded in ancient traditional Chinese medicine (TCM) books based on the Rules of Latent Structure Differentiation. Method:The 9 323 cough cases in the database of ancient TCM books and pulmonary diseases were extracted. At first, Lantern 5.0 software was used to construct the top 120 TCM hidden structure model with the frequency>100. Then, the obtained hidden variables were comprehensively clustered and interpreted. Result:The 46 hidden variables and 114 hidden classes were obtained through the modeling of 120 traditional Chinese medicines. According to the bayesian information measure (BIC) score, the model score was -161 242.92. The model diagram was formed with Y0, Y5, Y7, Y13, Y35 and Y38 as the cores, and Y36, Y38, Y24, Y19 and Y17 involved 4 hidden classes. Ten comprehensive clustering models were summarized according to the hidden structure flow chart, among which the highest score of Z5 external cold and internal decoction syndrome was 8.4, indicating that the result of syndrome differentiation rules of Z5 had a high degree of support, and the highest mutual information degree and information coverage of Pinellia sinensis were 0.31 and 63%. Z2 had a low score for the syndrome of deficiency of lung qi and Yin, which was -2, and Schisandra had the lowest score of -15, indicating that the syndrome differentiation rules of Z2 was less supportive. Forsythia and Notopterygium both had the highest score of Z6 wind-heat attack lung syndrome and Z10 phlegm and blood-stasis pulmonary syndrome, which was 19.1, indicating that these two TCMs had a great contribution to it. According to the test, the common syndromes of cough were cold and dryness attacking the lung, kidney-Yin deficiency, kidney-Yin deficiency of the lung, cold and internal decoction, wind heat invading the lung, liver fire invading the lung, lung heat burning, phlegm-dampness blocking the lung, phlegm-stasis blocking the lung. The newly discovered cough syndromes were external cold and internal rheum syndrome and phlegm-stasis blocking the lung syndrome. Conclusion:Based on the syndrome differentiation rules of hidden structure, the improved classification of cough syndromes provides ideas for the demonstration of tacit knowledge of TCM and methodological reference for the improvement of syndromes of other diseases, and is conducive to the development of valuable new prescriptions.
RESUMEN
To explore the medication rules of famous veteran traditional Chinese medicine (TCM) doctors in treatment of chronic bronchitis, a structured medical record database for famous veteran TCM doctors in modern clinical books was established. First, Lantern 3.1.2(Kongmin light) implicit structure analysis software was used to build an implicit structure model and make an implicit interpretation. Then, SAS 9.1 was adopted to mine herb-herb, herb-symptom and herb-syndrome association rules. Through the mining, 1 274 commonly used herbs for chronic bronchitis were found, including liquorice, bitter almond, pinellia, dried tangerine or orange peel, poria cocos. The medicine types included antiasthmatic medicine, qi-tonifying medicine, and heat-phlegm removing medicine. The medicine tastes included sweet, pungent and bitter. The meridian distributions included lung, spleen and stomach channels. The famous commonly used prescriptions included Xiaoqinglong decoction, Maxing Shigan decoction and Erchen decoction. The 147-herb implicit structure model for the first diagnosis was built to get 44 hidden variables, 88 hidden classes, 7 comprehensive clustering models, 9 dual herb associations, 50 triple herb associations and 89 quadruple associations. Totally 297 medical records for the second diagnosis were compared to obtain 24 herb-symptom associations, which reduced ephedra, bitter almond, pinellia and added poria cocos, atractylodes, dangshen, 20 dual herb associations and 8 triple herb associations. A model for the top 83 symptoms and top 96 herbs in the first diagnosis was built to get 50 hidden variables and 101 hidden classes. The commonly used herbs of famous veteran TCM doctors included bitter almond, pinellia, dried tangerine or orange peel, poria cocos, which feature mild property and sweet favor and enter lung, spleen, kidney meridians; the commonly herbal pairs included atractylodes and poria cocos, asarum, fructus schisandrae and pinellia, as well as poria cocos, dangshen, pinellia and dried tangerine or orange peel. The herb-syndrome associations involved ephedra, bitter almond, cassia twig and scanty sputum, pinellia and external cold and internal fluid syndrome, turbid phlegm obstructing lung syndrome and spleen deficiency syndrome, bitter almond and turbid phlegm obstructing lung syndrome, phlegm-heat accumulated in the lung and wind-cold invading the lung. The implicit structure model can be used to quantify tacit knowledge of TCM, extend to the herb and syndrome level for the first time, and quantify the major, minor and compatible statues of different variables in the same data. This study concluded that the medication rules of famous veteran TCM doctors in treatment of chronic bronchitis have certain reference value for the clinical diagnosis and treatment. The data sources, analysis methods and mining results were relatively reliable and objective, and can provide a reference for rules of other disease treatment based on syndrome differentiation.
RESUMEN
Previous studies showed that three methods for regulating and invigorating lung and kidney (lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, and Qi supplementing and kidney nourishing) could regulate inflammatory signaling pathways of chronic obstructive pulmonary disease (COPD) in rats, so as to alleviate inflammation. In the present study, R-value comprehensive evaluation method was used to evaluate the comprehensive effect of three methods for regulating and invigorating lung and kidney on inflammatory signaling pathways. Rats were randomly divided into control, model, lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline groups. The COPD rat models were established by cigarette smoking combined with bacterial infection, and orally administered with drugs between the 9th and 20th week. Afterwards, efforts were made to observe the long-term effects between the drug withdrawal and the 32rd week and detect indicators in two batches in the 20th week and 32th week. Specifically, (1) Linking JAK/STAT signaling pathway: JAK2 mRNA, and protein expressions of STAT-1, STAT-3, STAT-5, JAK-2; (2) NF-kappaB signaling pathway: Smad2 mRNA and protein expressions of I-kappaB, NF-kappaB, TGF-beta1; (3) PPARgamma and antioxidant signaling pathway: SOD, PGE mRNA, PPARgamma protein. According to the results, 5 indicators in JAK/STAT pathway, 4 indicators in NF-kappaB pathway, and 3 indicators in PPARgamma pathway were significantly rectified by three methods for regulating and invigorating lung and kidney in between the 20th week and 32nd week. Between the 20th and 32nd week, the recipes for rectifying JAK/STAT pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, Qi supplementing and kidney nourishing, lung invigorating and kidney tonifying, aminophylline, particularly those for lung invigorating and spleen strengthening; The recipes for rectifying NF-kappaB pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline, particularly the first three types of drugs. The recipes for rectifying PPARgamma and antioxidant signaling pathway with intensity from high to low were recipes for lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing, lung invigorating and spleen strengthening and aminophylline. Therefore, three methods for regulating and invigorating lung and kidney showed better long-term effects in regulating COPD lung inflammation signaling pathways. Specifically, recipe for lung invigorating and spleen strengthening showed a better effect in JAK/STAT and NF-kappaB pathways, while recipe for lung invigorating and kidney tonifying and Qi supplementing and kidney nourishing showed better effects in PPARgamma and antioxidant signaling pathways. In conclusion, R-value comprehensive evaluation method can evaluate the comprehensive effect of medicines and define the ranking of multiple drugs and their main targets.

In the study, the effects of Panax notoginseng saponins (PNS) on alveolar epithelial to mesenchymal transition (EMT) and extracellular matrix degradation were observed in a type of human alveolar epithelial cell, A549 cells, stimulated by TGF-beta1. Firstly, MTT method was applied to evaluation of cellular proliferation and found that PNS from 12.5 mg x L(-1) to 200 mg x L(-1) dosage could not inhibit significantly cellular proliferation. Then, cells were divided into five groups, normal group, TGF-beta1 group, TGF-beta1 + 50 mg x L(-1) PNS group, TGF-beta1 + 100 mg x L(-1) PNS group and TGF-beta1 + 200 mg x L(-1) PNS group. Normal cells were not stimulatec by TGF-beta1; TGF-beta1 cells were only stimulated by TGF-beta1 and the other cells were stimulated by TGF-beta1 with different doses of PNS, respectively. After stimulation, cells and supernatants were collected for assays. Cellular roundness was applied to quantitative evaluation of morphological change. Immunocytochemistry was applied to examine E-cadherion, a-SMA and FN proteins expression in the cells. Enzyme linked-immunosorbent assay was applied to MMP-9 and TIMP-1 levels. The results showed that EMT of A549 cells was induced by TGF-beta1, showing significant change of roundness, E-cadherion, alpha-SMA and FN (P < 0.05, P < 0.01). Compared to TGF-beta1, PNS significantly inhibited the changes of roundness (P < 0.05), FN and alpha-SMA (P < 0.05, P < 0.01) and not significantly inhibited the change of E-cadherion. Furthermore, MMP-9 levels were significantly increased by TGFbeta1 stimulation (P < 0.05), without significant change of TIMP-1. Compared with TGF-beta1, PNS could significantly increase MMP-9 level (P < 0.05) and decrease TIMP-1 levels (P < 0.05, P < 0.01). In conclusion, PNS could inhibit alveolar epithelial cell EMT induced by TGF-beta1, with increase of extracellular matrix degradation ability, which showed anti-fibrosis of lung ability.

<p><b>OBJECTIVE</b>To evaluate the impact and long-term effect of three prescriptions regulating and tonifying lung and kidney (prescription tonifying lung and spleen, prescription tonifying lung and kidney, and prescription tonifying Qi and kidney) on JAK/STAT signaling of COPD rats.</p><p><b>METHOD</b>Rats were randomly divided into the control group, the model group, the Bufeijianpi group, the Bufeiyishen group, the Yiqizishen group and the aminophyline group. The COPD rat model was established by smoke inhalations and bacterial infections. In the 9th week, the control group and the model group were administered with normal saline, while the remaining groups are orally given corresponding medicines. In the 20th and 32nd week, the rats were sacrificed in batches to observe the pathology in their lung tissues, protein expressions of JAK2, STAT1, STAT3, STAT5, and expressions of JAK2 and SOCS3 mRNA.</p><p><b>RESULT</b>In the 20th and 32nd week, protein expressions of JAK2 mRNA and phosphorylation-JAK2, STAT1, STAT3 and STAT5 in the model group were higher than the control group (P < 0.01), whereas the three traditional Chinese medicine (TCM) (Bufeijianpi, Bufeiyishen and Yiqizishen) groups and the aminophyline group were significantly lower (P < 0.05, P < 0.01). The expression of SOCS3 mRNA in the model group was higher than the control group (P < 0.01), whereas the level was notably higher in the three TCM groups and the aminophylline group (P < 0.01). The three TCM groups were remarkably higher than the aminophylline group (P < 0.05, P < 0.01). Compared with the figures in the 20th week, JAK2 mRNA and phosphorylation-JAK2, STAT3 and STAT5 were significantly lower in the Bufeijianpi group in the 32nd week (P < 0.05, P < 0.01), and so did phosphorylation-STAT3 in Bufeiyishen group (P < 0.01) and phosphorylation-STAT3 and STAT5 in the Yiqizishen group (P < 0.05, P < 0.01). However, the aminophylline group showed no significant difference in above indicators.</p><p><b>CONCLUSION</b>The three medicines regulating and tonifying lung and kidney can effectively relieve injury of lung tissues, and have long-term effect, which may be related to the regulation of JAK/ STAT signaling. Specifically, prescription tonifying lung and spleen shows good effect in reducing JAK2, STAT3 and STAT5, prescription tonifying lung and kidney shows good effect in reducing p-STAT3, and prescription tonifying Qi and kidney shows good effect in reducing p-STAT3 and p-STAT5.</p>

<p><b>BACKGROUND</b>Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. Pulmonary rehabilitation (PR) is an established intervention for the management of patients with COPD. Exercise training is an important part of PR, and its effectiveness in patients with COPD is well established. However, alternative methods of PR training such as Daoyin have not been appropriately studied. Hence, alternative forms of exercise training that require less exercise equipment and no specific training place should be evaluated. This paper describes the study protocol of a clinical trial that aims to determine if pulmonary Daoyin training will improve the exercise capacity and psychosocial function of patients with COPD in China.</p><p><b>METHODS AND DESIGN</b>A multicenter, randomized, controlled trial will be conducted. A total of 464 patients meeting the inclusion criteria will be enrolled into this study with 232 patients in each of the trial group and the control group. Based on patient education, patients in the trial group will receive pulmonary Daoyin and continue with their usual therapy for three months. In the control group, patients will continue with their usual therapy. The primary outcome measures are exercise capacity assessed by the six-minute walking distance test and lung function. Secondary outcomes include dyspnea and quality of life. Measurements will be taken at baseline (month 0) and after the study period (month 3).</p><p><b>DISCUSSION</b>It is hypothesized that pulmonary Daoyin will have beneficial effects in improving exercise capacity and psychosocial function of patients with stable COPD, and will provide an alternative form of exercise training that is accessible for the large number of people with COPD.</p><p><b>TRIAL REGISTRATION</b>This trial has been registered in ClinicalTrials.gov. The identifier is NCT01482000.</p>

Rats in the RFIP group, the RFIS group, the BQNS group, and the aminophylline group were administrated with Bufei Jianpi Recipe, Bufei Yishen Recipe, Yiqi Zishen Recipe, and aminophylline from week 9 to 20. After rats were sacrificed at week 20 and 32, lung pathological impairments and the levels of T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+ / CD8+) and CD4+ CD25+ in the peripheral blood and the bronchoalveolar lavage fluid (BALF) were detected.</p><p><b>RESULTS</b>At week 20 and 32, the impairments in the lungs were obvious in rats of the model group, while the levels of CD3+, CD4+, CD8+, and CD4+ CD25+ were significantly lower in the peripheral blood and the BALF in the model group than in the controls group (P < 0.05, P < 0.01), and they were higher in the four groups than in the model group (P < 0.05, P < 0.01). However, the levels of CD3+ and CD4+ in the peripheral blood and the BALF were higher in the three TCM-treated groups than in the aminophylline group (P < 0.05, P < 0.01). CD4+ in the peripheral blood in the RFIP group was higher than in the RFIS group and the BQNS group (P < 0.01). At week 20, the ratio of CD4+ /CD8+ was higher in the RFIP group than in the aminophylline group (P < 0.01). CD4+ was higher in the three TCM-treated groups than in the aminophylline group (P < 0.05, P < 0.01). At week 32, the ratio of CD4+ / CD+ in the three TCM- and aminophylline-treated groups was higher than that of the model group (P < 0.05). CD4+ in the RFIP group and the RFIS group was higher than that of the aminophylline group (P < 0.05, P < 0.01). Compared with that at week 20, the ratio of CD4+/CD8+ in the BALF group was significantly higher in the RFIP at week 32 (P < 0.05). The CD4+ CD25+ levels in the peripheral blood and BALF of the BQNS group was significantly lower (P < 0.05).</p><p><b>CONCLUSIONS</b>The efficacy and long-term effects of three methods for regulating and invigorating Fei-Shen might be possibly associated with regulating T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+ / CD8+) and CD4+ CD25+ levels. Of them, RFIP showed significant effects in regulating CD4+ and CD4+ / CD8+ in the peripheral blood and BALF.</p>

Objective. This study was intended to evaluate the efficacy and safety of ligustrazine injection for chronic pulmonary heart disease (CPHD). Method. Randomized controlled trials (RCTs) of clinical therapeutic studies on CPHD when using ligustrazine injection were included. Searches were applied to the following electronic databases: the PubMed, the Cochrane Library, EMBASE, CBM, and AMED. No language restriction was used. All trials included were analyzed according to the criteria of the Cochrane Handbook. Review Manager 5.0 software was used for data analysis. Result. 34 RCTs with low methodological quality were included. Compared to conventional medicine treatment alone, ligustrazine injection plus conventional medicine treatment showed improvement in New York Heart Association classification of clinical status (Odds ratio 0.22; 95% CI 0.17 to 0.28) and depression of pulmonary artery hypertension (weighted mean difference -4.77; 95% CI -5.85 to -3.68). Three studies had reported adverse events. No serious adverse effects were reported. Conclusion. While there is some evidence that suggests potential effectiveness of ligustrazine injection for CPHD, the results were limited by the methodological flaws of the studies. High quality studies are needed to provide clear evidence for the future use of ligustrazine injection.
RESUMEN
<p><b>OBJECTIVE</b>To observe the effects of Bufei Jianpi Recipe (BJR) on the diaphragmatic neural discharge and the diaphragmatic muscle function in rats with chronic obstructive pulmonary disease (COPD).</p><p><b>METHODS</b>Rats were randomly divided into the normal control group, the model group, the high dose BJR group (9.68 g/kg x d(-1)), the medium dose BJR group (4.84 g/kg x d(-1)), the low dose BJR group (2.42 g/kg x d(-1)), and the aminophylline group (2.3 mg/kg x d(-1)). The stable phase COPD rat model was prepared using repeated smoke inhalations and bacterial infections. The high, medium, and low dose BJR and aminophylline was respectively administered to rats from the ninth week to the twentieth week. The sampling was taken. The lung function, diaphragmatic neural discharge time (Td), and diaphragmatic neural discharge interval (Tdi), diaphragmatic neural discharge range (Rd), diaphragmatic neural discharge area (Ad), expiratory time (Tex), inspiratory time (Tin), respiratory rate (RR), respiratory excursion (RE), respiratory area (RA), and diaphragmatic muscular tension and endurance were detected.</p><p><b>RESULTS</b>Compared with the normal control group, the tidal volume (TV), peak expiratory flow (PEF), and 50% tidal volume expiratory flow (EF50) significantly decreased in the model group (P < 0.01). Td, Tdi, Tex, and Tin were significantly prolonged (P < 0. 05, P < 0.01). Ad, Rd, RR, RE, RA, diaphragmatic muscular tension and endurance significantly decreased (P < 0.05, P < 0.01). The ratio of type I and IIA diaphragmatic fibers significantly increased and type IIB significantly decreased (P < 0.01). The activity of ATP decreased and the activity of SDH increased (P < 0.01). The aforesaid indices were improved to different degrees in BJR groups, especially in the high dose BJR group and the medium dose BJR group (P < 0.05, P < 0.01).</p><p><b>CONCLUSIONS</b>BJR could significantly improve the diaphragmatic neural discharge and the diaphragmatic muscle function. Its efficacy was better than that of aminophylline.</p>

Chronic obstructive pulmonary disease (COPD) remains a severe public health problem. Acute exacerbation of COPD (AECOPD) is a major factor that influences the process of COPD. Strengthening the treatment of AECOPD is very essential. AECOPD risk window (AECOPD-RW) refers to the period from AECOPD remission to the time before the stable phase. The condition is very unstable. Symptoms are relieved but continually exist. The lung function has not restored to the levels of the stable phase. The inflammatory reactions continually exist. In this period patients are most liable to suffer from AECOPD, resulting in higher hospital admission rate and higher mortality. Dispelling pathogens should be taken as the main principle for AECOPD treatment. However, when it transforms from AECOPD to AECOPD-RW, strengthening the body resistance should be taken as the main principle. The proposal of AECOPD-RW has provided new thoughts and strategies for COPD. In this period deficiency syndrome dominates, most being lingering pathogens due to deficient vital qi. Qi deficiency and qi-yin deficiency are the most common syndromes, involving Fei, Pi, and Shen. Deficiency of both Fei and Shen dominates, complicated with phlegm and stasis. Therefore, the treatment principle of AECOPD-RW should focus on tonifying the deficiency and strengthening the body resistance, assisted with dissipating phlegm and activating blood circulation.
