From the perspective of state differentiation and treatment， it is believed that the pathogenesis of acute respiratory distress syndrome （ARDS） is that evil poisons injured the lungs， and the lung qi suddenly collapsed， then blocked and exhausted， and the qi failure to control blood and liquid， then the fluids overflow outside the vessels， and damp phlegm， stasis， and toxins became knotted up in the body， which ultimately leads to qi dysfunction， and a series of symptom arise， so qi impairment is the principal mechanism of ARDS. A combination of Chinese and Western medicine was proposed to treat ARDS by combining tangible qi and intangible qi， using Chinese herbal medicine to boost qi and relieve collapse， percolate and drain dampness with bland medicinals， resolve toxins and dissolve stasis， and regulate qi， and combining with Western medicine to assist qi circulation to improve qi's consolidation， propulsion， and transformation， so as to make the evil qi go away， the positive qi restored， the viscera qi circulated， qi， blood， yin， and yang connected， and the activities of life maintained， and thus to achieve the goal of treating ARDS by integrated Chinese medicine and Western medicine.

Primary multiple pulmonary nodules have a high incidence,and the size and number of pulmonary nodules on computed tomography images increase with time.Postoperative pathology of multiple pulmonary nodules shows chronic inflammation,adenomatoid change,carcinoma in situ,microinvasive carcinoma,infiltrating carcinoma,and other forms.There is a possibility of"inflammation-cancer transformation"in multiple pulmonary nodules with prolonged time and external irritation.The accumulation of dampness phlegm and blood stasis is the basis of the theory of"inflammation-cancer transformation."Healthy qi deficiency is the key to the"inflammation-cancer transformation."Qi and yang deficiency are the root cause of healthy qi depletion.Emotional depression,dampness,phlegm,and blood stasis transforming into toxins provide the impetus for"inflammation-cancer transformation."There are struggle between healthy qi and evil qi,and waxing and waning of dampness,phlegm and blood stasis in the process of"inflammation-cancer transformation."The dampness phlegm and blood stasis will increase when evil qi increases and healthy qi decreases.In contrast,the size,number,and malignancy of nodules will increase during healthy qi deficiency,showing a dynamic shift from inflammation to atypical adenomatous hyperplasia to cancer.The dampness phlegm and blood stasis will be absorbed as the healthy qi increases and evil qi decreases so that lung cancer can be reversed.External irritation,such as acute inflammatory stimulation,may accelerate the transformation of"inflammation-cancer"in multiple pulmonary nodules.

ObjectiveTo observe the clinical efficacy and safety of treating mediate-risk pure ground glass pulmonary nodules （pGGNs） based on the state theory. MethodsA prospective clinical randomized controlled trial was used. Totally 141 cases of mediate-risk pGGNs were divided into treatment group （92 cases） and control group （49 cases） according to the random table method. The treatment group was given the basic Sanjie Formula （基础散结方） orally with modification according to the identification of traditional Chinese medicine （TCM） state， 1 dose per day， 3 months as a course of treatment.Three months after the treatment patients were checked by CT. Patients who were clinically judged as cure， moderate to low risk， and turned to surgical resection do not carry out a second course of treatment，and the rest of the patients continued to complete the second courses. Patients in the control group did not receive any treatment and were only followed up periodically. Patients in both groups received a CT review 3 months and 6 months after enrolled. Comprehensive curative effect was evaluated according to the reduction rate of the area of pulmonary nodules shown in chest CT， to further explore the clinical effective difference for patients at different TCM state； the risk of malignancy index （Mayo score） was calculated by Mayo model at enrollment and 3 months and 6 months after enrolled. Adverse events were monitored continuously during the study. ResultsDuring the follow-up， 8 cases in the treatment group and 7 cases in the control group were lost. A total of 126 cases completed the whole process， including 84 cases in the treatment group and 42 cases in the control group. The total effective rates at 3 months and 6 months of the treatment group were 46.15% （30/65） and 45.71% （32/70） in the treatment group， while the total effective rates at 3 months and 6 months in the control group were 12.5% （4/32） and 10.00% （4/40）. Compared with the control group， the comprehensive curative effect of 3 months and 6 months of enrollment in treatment group was significantly better than that in corresponding control group （P＜0.01）. The pulmonary nodule area and Mayo score in the treatment group decreased after 3 and 6 months of enrollment （P＜0.01）. In contrast， there was no statistically significant difference in nodule area between pre- and post-enrollment time points in the control group （P＞0.05）， and probability of Mayo risk increased in the control group after 6 months of enrollment compared to pre-enrollment （P＜0.05）. Among the 84 patients in the treatment group， there were 15 cases of qi deficiency state， 7 cases of yin deficiency state， 5 cases of yang deficiency state， 20 cases of qi depression state， 32 cases of damp-heat state， and 5 cases of harmonious state； the difference in the distribution of the total clinical effective rate of the patients with different TCM states after treatment was statistically significant （P＜0.05）， and the total effective rate of two-by-two comparison of qi depression state was higher （13/20，65.00%） than that of the total effective rate of damp-heat state （8/32，25.00%， P＜0.00833）. There were no significant changes in blood routine， urine routine， liver function and kidney function in both groups， and no adverse events occurred. ConclusionTreating mediate-risk pGGNs based on the state theory can effectively reduce the area of pulmonary nodules and inhibit the growth of malignant risk of pulmonary nodules.

ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.

OBJECTIVETo observe the influence of the 4 parts of forming of Yiqi Qingwen Jidu Heji(YQQWJDHJ) to lung inflammatory cytokines of the model rats infected with influenza virus dynamically, and to discuss the mechanism of 4 parts of forming to anti-influenza immune injury and restoration.

METHODAt the different stages of infection with the model rats infected by FM1 influenza, expression in lung of TNF-alpha, IL-6, IL-1, IL-10 and IFN-gamma was detected after the intervention of 4 parts of forming using ELISA method.

RESULTThe expression of TNF-alpha, IL-6, IL-1 and IFN-gamma of model rats infected by FM1 were higher than the control group, the expression of IL-10 did not change. The expression of TNF-alpha was significantly reduced in 3 to 5 days after infection. By the method of relieving superficies with acrid-cold, clearing away heat and poison and replenishing Qi, the lung expression of IFN-gamma was significantly increased in the stage after infection.

Japanese kampo medicine originated from traditional Chinese medicine. But different from TCM pattern of "Tracing the etiology by syndrome differentiation-establishing therapeutic methods-prescribing formula", during the process of development, Japanese kampo medicine has gradually formed a different diagnostic and therapeutic mode, which was "corresponding prescription and pattern". This therapeutic mode directly chose formula from ancient books, especially Shanghanlun (Treatise on Febrile Diseases), according to the constitution, symptoms and signs of patients. The diagnostic and therapeutic mode of Japanese kampo medicine provides references for integration of traditional Chinese and western medicine.

To observe the effects of tetramethylpyrazine (TMP) on the proliferation and type I collagen synthesis of rat cardiac fibroblasts (CFBs) induced by angiotensin II (Ang II), and to explore the mechanism of TMP in treating myocardial fibrosis.

OBJECTIVE: To observe the effects of Feixian Formula, a compound traditional Chinese herbal medicine for treating pulmonary fibrosis, on bleomycin-induced pulmonary fibrosis in rats, and its influence on serum transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factor (PDGF). METHODS: Seventy-two male Wistar rats were infused with bleomycin (1 mg/kg) through tracheal intubation to induce pulmonary fibrosis, and they were randomly divided into untreated group (n=24), prednisone-treated group (n=24) and Feixian Formula-treated group (n=24). Fifteen male Wistar rats of the sham-operated group were infused with equivalent normal saline. Twenty-four hours after operation, prednisone (5 mg/kg) and Feixian Formula (1.25 g/kg) were given to the prednisone-treated group and Feixian Formula-treated group respectively by intragastric administration once a day. Equivalent saline was administered to rats of the untreated group and sham-operated group. On the 14th, 28th and 45th day, 5 rats in the sham-operated group and 8 rats in each of the other three groups were dissected to observe pathologic changes of the lung tissues, and the levels of serum TGF-beta1 and PDGF were determined by enzyme-linked immunosorbent assay. RESULTS: At the 45th day, the degree of pulmonary interstitial fibrosis was lesser in rats of the Feixian Formula-treated group as compared with those of the untreated group and prednisone-treated group. The levels of serum TGF-beta1 and PDGF were increased, and were significantly higher than those of the sham-operated group, especially on the 45th day (P<0.05). Changes of TGF-beta1 level in the prednisone-treated group and the Feixian Formula-treated group were similar to untreated group (P>0.05), and there was no significant difference between the prednisone-treated group and the Feixian Formula-treated group (P>0.05). PDGF in the Feixian Formula-treated group reached the highest level on the 14th day, significantly higher than those of the other three groups (P<0.01). Then it decreased, and was close to that of the sham-operated group on the 45th day (P=0.792). The levels of PDGF in untreated group and prednisone-treated group were increased depending on time, and were obviously higher than that of the sham-operated group on the 45th day (P<0.01). CONCLUSION: Feixian Formula can relieve bleomycin-induced pulmonary fibrosis in rats, and the mechanism of its action may be related to down-regulating serum PDGF.

OBJECTIVE: To study the approach for developing a rat model of pulmonary fibrosis induced by bleomycin (BLM). METHOD: Different doses (7, 6, 5, 3.4, 2, 1 mg/kg) of bleomycin A5-saline were infused into the rats' lung in bleomycin-treated group through tracheal intubation, and rats in sham-operated group were infused with same volume of saline. The living state and lung pathology of the rats were observed. The author deeply studied the condition of the rats in 1 mg/kg bleomycin-treated group, and the changes of body weight and lung pathology were observed. Lung quotient, the content of transforming growth factor beta1(TGF-beta1) and platelet-derived growth factor (PDGF) in serum were measured on the 14th, 28th and 45th day of the experiment. RESULTS: The study demonstrated that infusing large doses of bleomycin A5 quickly through tracheal intubation had a high mortality, and infusing 1 mg/kg quickly could successfully develop an animal model of pulmonary fibrosis. Compared with the sham-operated group, fibrosis was appeared obviously in the rats' lung in 1 mg/kg bleomycin A5-treated group after 14 days of experiment, diffuse fibrosis was appeared after 28 days of experiment, and the fibrosis became more severe after 45 days of experiment. The body weight of the rats in bleomycin-treated group was declined after 3, 7 and 14 days of experiment as compared with the sham-operated group (P<0.01). Twenty-one days after the experiment, the body weight was declined too, but there was no significant difference between the bleomycin-treated group and the sham-operated group (P>0.05). Lung quotient was increased 14, 28 and 45 days after the experiment (P<0.01), the level of serum TGF-beta1 began to increase since 28 days after the experiment (P<0.05, P<0.01), and the level of serum PDGF also increased gradually 45 days after the experiment (P<0.05). And the mortality rate of 1 mg/kg bleomycin A5-treated group was lower than those of the other doses of bleomycin A5-treated groups. CONCLUSION: A rat model of pulmonary fibrosis can be duplicated successfully by infusing 1 mg/kg bleomycin A5 quickly through tracheal intubation.
