Objectives: Patients with respiratory diseases are increasing as air pollution due to fine dust gets worse. Diseases that occupy a large proportion of respiratory diseases in medical institutions are acute bronchitis, chronic bronchitis and Allergic rhinitis. The number of patients with all three diseases is gradually increasing. This study was to suggest assignment of medicine policy for improving accessibility to Korean medical treatment of respiratory diseases analyzing the current treatment status of acute bronchitis, Chronic bronchitis and Allergic rhinitis patients in Western medical and Korean medical institutes in this situation. Methods: This study used 2017 National patient sample data from the Korean Health Insurance Review and Assessment Service for research. Acute bronchitis, Chronic bronchitis, Allergic rhinitis was according to KCD code. This research contains Socio-demographic analysis classified by sex and age, the number of three disease's patients. Also the number of medical treatment, the expense of recuperation cost, medical practices were analyzed compare with Western and Korean medicine. Results: The incidence of three diseases is higher among female than male. There are many patients under the age of 10 in the case of acute bronchitis and allergic rhinitis, while there are many patients over 50 years of age in chronic bronchitis. Western medical treatment take up a larger proportion than Korean medical treatment in part of the number of three disease's patients, the number of medical treatment, the expense of recuperation cost. Conclusions: Much more patients of these diseases visit in Western medical clinic and hospital than Korean medical clinic and hospital for treatment. There are many parts of Korean medical treatment that are not covered by Health insurance benefits like herbal decoction, pharmacopuncture, etc. Korean medicine need to do the efforts for expanding medical field in variety. Also it is demanded for institutional support for reduction of the cost burden and improving on accessibility of Korean medical treatment in order to treat with the increase in respiratory diseases due to fine dust.

Broussonetia papyrifera and Lonicera japonica have long been used in the treatment of inflammatory disorders in Chinese medicine, especially respiratory inflammation. Previously, a new phytoformula (BL) containing B. papyrifera and L. japonica was found to exert strong anti-inflammatory activity against several animal models of inflammation, especially against an animal model of acute bronchitis. In the present investigation, the effects of BL on animal models of septic inflammation and chronic bronchitis are examined. Against lipopolysaccharide (LPS)-induced septic inflammation in mice, BL (200-400 mg/kg) reduced the induction of some important proinflammatory cytokines. At 1 h after LPS treatment, BL was found to considerably inhibit TNF-${\alpha}$ production when measured by cytokine array. At 3 h after LPS treatment, BL inhibited the induction of several proinflammatory cytokines, including IFN-${\gamma}$ and IL-$1{\beta}$, although dexamethasone, which was used as a reference, showed a higher inhibitory action on these biomarkers. Against chronic bronchitis induced by LPS/elastase instillation in rats for 4 weeks, BL (200-400 mg/kg/day) significantly inhibited cell recruitment in bronchoalveolar lavage fluid. Furthermore, BL considerably reduced lung injury, as revealed by histological observation. Taken together, these results indicate that BL may have a potential to treat systemic septic inflammation as well as chronic bronchitis.

Background: Chronic bronchitis (CB) is an important phenotype in chronic obstructive pulmonary disease (COPD). The purpose of this study is to evaluate different pattern of COPD assessment test (CAT) score between CB and non-CB patients. Methods: Patients were recruited from 45 centers in Korea, as part of the Korean COPD Subgroup Study cohort. CB was defined when sputum continued for at least 3 months. Results: Total 958 patients with COPD were eligible for analysis. Among enrolled patients, 328 (34.2%) were compatible with CB. The CAT score was significantly higher in patients with CB than non-CB, and each component of CAT score showed a similar result. CB was significantly associated with CAT score when adjusted with age, sex, modified Medical Research Council, and post-bronchodilator forced expiratory volume in 1 second. Each component of CAT score between patients with CB and non-CB showed different pattern according to Global Initiative for Chronic Obstructive Lung Disease grade. Conclusion: CAT score is significantly higher in patients with CB than non-CB. Each component of CAT score was significantly different between two groups.

Background: Chronic cough is a common symptom that requires the systematic diagnostic approach for proper evaluation. Postnasal drip syndrome(PNDS), bronchial asthma, gastroesophageal reflux disease(GERD), and chronic bronchitis are among the common causes. This study was conducted to evaluate the spectrum and the frequency of the causes of chronic cough. Methods: We prospectively evaluated 93 patients who had chronic cough despite normal chest radiographic finding. History and physical examination were done along with paranasal sinus radiograph, spirometry, bronchoprovocation test and 24-hours' ambulatory aesophageal pH monitoring as necessary. Results: Forty-nine(52%) of the 93 patients had PNDS, 15 patients(16%) bronchitis, 10 patients(11%) asthma, 4 patients (4%) GERD, 7 patients (8%) both PNDS and asthma, 4 patients (4%) undiagnosed condition and 4 patients(4%) were taking ACE inhibitor. Sixty-nine percent of the patients with PNDS improved after follow up, 73% patients with bronchitis, 80% patients with asthma, 50% patients with GERD, 100% patients with both PNDS and asthma, and 100% patients with ACE inhibitor. Conclusion: PNDS was the most common causes of chronic cough. Bronchitis was the second and asthma the third in frequency. The etiology of chronic cough can be determined easily by history and physical examination, successful therapy initiated in most patients. The response to specific therapy also was important in evaluation of chronic cough.

Background : Excessive extracellular matrix (ECM) deposition by airway inflammation is presumed to play an important role in the pathogenesis of worsening airflow obstruction (Ed- acceptable three-word noun) seen during acute exacerbations of chronic bronchitis. Although many proteases can cleave ECM molecules, matrix metalloproteinases (MMPs) and their inhibitors are likely to be the physiologically relevant mediators of ECM degradation. Objectives ; The purpose of this study was to demonstrate that antibiotic treatment can change airway MMPs and TIMP-1 concentrations/levels by controlling airway inflammation in acute exacerbation of chronic bronchitis. Methods : We studied 40 patients, all of whom had an acute exacerbation of chronic bronchitis. The patients were treated with two different antibiotics, moxifloxacin and clarithromycin, in a double-blind manner for 7 days. Sputum samples were induced and collected before and after antibiotic therapy. We measured the sputum concentration of MMP-1,-9, TIMP-1, IL-8 and secretory leukocyte proteinase inhibitor (SLPI) in sputum supernatants by ELISA method. Results : There was no difference after antibiotic treatment in the sputum concentrations of MMP-1,-9, TIMP-1, IL-8 and SLPI between the patients treated with moxifloxacin and those treated with clarithromycin. But the sputum concentrations of TIMP-1, and SLPI, and the TIMP-1/MMP-1 ratio were significantly reduced by the antibiotic therapy. There were significant positive correlations between sputum TIMP-1 levels and IL-8 levels (p<0.01, r=0.751), and between the sputum TIMP-1/MMP-1 ratio and IL-8 levels (p<0.01, r=0.752). The sputum SLPI levels were significantly elevated by antibiotic treatment and were negatively correlated with sputum TIMP-1 levels (p<0.01, r=-0.496) and TIMP-1/MMP-1 levels (p<0.01, r=-0.456). Conclusion : The study shows that the worsening of airway inflammation in acute exacerbation of chronic bronchitis is associated with an imbalance between the concentrations/levels of TIMP-1 and MMPs. Antibiotic treatment can prevent progression of airway narrowing in acute exacerbation of chronic bronchitis by modulation of the protease and anti-protease imbalance.

Chronic cough is one of the most common respiratory symptoms, especially in children. And it can be the sale presenting manifestation of bronchial asthma. Although most coughs are self limiting, chronic cough often proves to be a frustrating problem. It is commonly defined as a persistent or recurrent cough exceeding 3weeks duration. The post nasal syndrome has been determined to be the most common cause of chronic cough, followed by asthma, chronic bronchitis, gastroesophageal reflux and bronchiectasis. This study was performed at both City-Oriental Medicine Hospital and Pundang Cha Oriental Medicine Hospital from January,1,1998 to November 31,1998, and 114 children with chronic cough persisting for longer than 3 weeks were evaluated. We investigated the clinical findings and evaluated the etiology in children with chronic cough syndrome including: type of cough (with or with out sputum and daily onset) and associated signs & symptoms. The results were as follows: The most common cause of chronic cough was asthma with sinusitis (27.2%); The second and third were post nasal drip syndrome(22.8%) and bronchial hypereactivitic cough(14.9%). The other causes included asthma, paranasal sinusitis, bronchitis and rhinitis. Therefore, in the diagnostic and therapeutic approach to this symptom, it should be considered that the cause of this type of cough is either bronchus and pulmonary disease or that associated with another problem, especially sinusitis, gastroesophageal reflux and allergic disease. Also, in infants and toddlers, congenital abnormaly should be considered.

Quantitative sputum cytometry facilitates in assessing the nature of bronchitis associated with exacerbations of chronic obstructive pulmonary disease (COPD). This is not assessed in most clinical trials that evaluate the effectiveness of strategies to prevent or to treat exacerbations. While up to a quarter of exacerbations may be associated with raised eosinophil numbers, the vast majority of exacerbations are associated with neutrophilic bronchitis that may indicate airway infections. While eosinophilia may be a predictor of response to corticosteroids (oral and inhaled), the limited efficacy of anti-interleukin 5 therapies would suggest that eosinophils may not directly contribute to those exacerbations. However, they may contribute to airspace enlargement in patients with COPD through various mechanisms involving the interleukin 13 and matrix metalloprotease pathways. The absence of eosinophils may facilitate in limiting the unnecessary use of corticosteroids. The presence of neutrophiia could prompt an investigation for the specific pathogens in the airway. Additionally, sputum measurements may also provide insight into the mechanisms of susceptibility to airway infections. Iron within sputum macrophages, identified by hemosiderin staining (and by more direct quantification) may impair macrophage functions while the low levels of immunoglobulins in sputum may also contribute to airway infections. The assessment of sputum at the time of exacerbations thus would facilitate in customizing treatment and treat current exacerbations and reduce future risk of exacerbations.

Background: Lung cancer was one of the most common cancers in both men and women all over the world. In this study, we aimed to clarify who could survive after long term chemotherapy in patients with advanced non-small cell lung cancer (NSCLC). Methods: We enrolled 186 patients with stage IV NSCLC after long term chemotherapy from Jun 2006 to Nov 2014 diagnosed in Jiangsu Cancer Hospital. Multiple variables like age, gender, smoking, histology of adenocarcinoma and squamous-cell cancer, number of metastatic sites, metastatic sites (e.g. lung, brain, bone, liver and pleura), hemoglobin, lymphocyte rate (LYR), Change of LYR during multiple therapies, hypertension, diabetes, chronic bronchitis, treatments (e.g.radiotherapy and targeted therapy) were selected. For consideration of factors influencing survival and response for patients with advanced NSCLC, logistic regression analysis and Cox regression analysis were used in an attempt to develop a screening module for patients with elevated survival after long term chemotherapy become possible. Results: Of the total of 186 patients enrolled, 69 survived less than 1 year (short-term group), 45 one to two years, and 72 longer than 3 years (long-term group). For logistic regression analysis, the short-term group was taken as control group and the long-term group as the case group. We found that age, histology of adenocarcinoma, metastatic site (e.g. lung and liver), treatments (e.g. targeted therapy and radiotherapy), LYR, a decreasing tendency of LYR and chronic bronchitis were individually associated with overall survival by Cox regression analysis. A multivariable Cox regression model showed that metastatic site (e.g. lung and liver), histology of adenocarcinoma, treatments (e.g. targeted therapy and radiotherapy) and chronic bronchitis were associated with overall survival. Thus metastatic site (e.g. lung and liver) and chronic bronchitis may be important risk factors for patients with advanced NSCLC. Gender, metastatic site (e.g. lung and liver), LYR and the decreasing tendency of LYR were significantly associated with long-term survival in the individual-variable logistic regression model (P<0.05). On multivariate logistic regression analysis, gender, metastatic site (e.g. lung and liver) and the decreasing tendency of LYR associated with long-term survival. Conclusions: In conclusion, female patients with stage IV adenocarcinoma of NSCLC who had decreasing tendency of LYR during the course therapy and had accepted multiple therapies e.g. more than third-line chemotherapy, radiotherapy and/or targeted therapy might be expected to live longer.

Background : Unexplained weight loss, which commonly occurs in patients with chronic obstructive pulmonary disease(COPD), is important because weight loss is an independent risk factor of mortality and morbidity in these patients. Leptin is known to play an important role in regulating body weight. In addition, the tumor necrosis factor($TNF-{\alpha}$) might also play a potential role in the weight loss experienced in chronic wasting disease. The aim of this study was to determine the influence of plasma leptin and the circulating $TNF-{\alpha}$ system to the difference in the body compositions in patients with COPD. Methods : Spirometry, body composition analysis and the plasma concentrations of leptin, $TNF-{\alpha}$ and a soluble TNF receptor (STNF-R55, -R75) were measured in 31 patients with chronic bronchitis and 10 patients with emphysema. The COPD subtype was classified by the transfer coefficient of carbon monoxide, DLco/VA. Results : The circulating levels of leptin were significantly lower in those patients with emphysema($108.5{\pm}39.37pg/ml$) than those with chronic bronchitis($180.9{\pm}57.7pg/ml$). The circulating levels of sTNF-R55 were significantly higher in the emphysema patients($920.4{\pm}116.4pg/ml$) than in those with chronic bronchitis($803.2{\pm}80.8pg/ml$). There was no relationship between the circulating leptin levels and the activated TNF system in patients with chronic bronchitis and emphysema. However, the circulating leptin levels correlated well with the BMI and fat mass in both patient groups. Conclusion : These results suggest that the weight loss noted in emphysema patients may be associated with the activation of the $TNF-{\alpha}$ system rather than the plasma leptin level.
