Abstract
The QuEChERS (quick, easy, cheap, effective, rugged and safe) conditions were optimized for efficient determination of the U.S. Environmental Protection Agency (US EPA) and European Union (EU) priority polycyclic aromatic hydrocarbons (PAHs) for the categories of grains, tuber & starchy vegetables, soy beans and products, fish & seafood, and poultry & meat, including raw materials and their corresponding products. The PAHs were analyzed using ultrahigh-performance liquid chromatography with temperature-controlled fluorescence detection and gas chromatography with tandem mass spectrometry. The established conditions had good accuracy, repeatability, and precision. Environmental pollution and processing methods influence the level of PAHs in samples. The low molecular weight PAHs were present in all raw materials, and processing increased high and low molecular weight PAHs in the products. The excess cancer risk for consumption of PAHs in cooked samples was mostly acceptable; a small number of samples might be of slight concern in certain age groups.

Abstract
In an in vitro culture system, primary hepatocytes usually display a low proliferation capacity, accompanied with a decrease of viability and a loss of hepatocyte-specific functions. Previous studies have demonstrated that the combination introductions of certain hepatocyte-specific transcription factors are able to convert fibroblasts into functional hepatocyte-like cells. However, such combinational usage of transcription factors in primary hepatocytes culture has not yet sufficiently studied. The forkhead box protein A3 (FoxA3) and hepatocyte nuclear factor 4α (Hnf4α) are liver-enriched transcription factors that play vital roles in the differentiation, and maintenance of hepatocytes. Thus, we simultaneously overexpressed the two genes, Foxa3 and Hnf4α, in rat hepatocytes and observed that the combinational augmentation of these two transcription factors have enhanced the proliferation and stabilized the hepatocyte-specific functions of primary hepatocytes over a long-term culture period.

Abstract
Objective: To investigate the application value of household dynamic monitoring of exhaled nitric oxide (FeNO) and pulmonary ventilation function in daily management of asthma. Methods: A total of 22 untreated patients with uncontrolled asthma who visited the Respiratory Disease Clinic of China-Japan Friendship Hospital from October 2019 to December 2020 were enrolled. Demographic characteristics, asthma history, comorbidities, asthma control test (ACT), and mini-asthma quality of life questionnaire (mini-AQLQ) were collected through face-to-face surveys. FeNO, pulmonary ventilation function, sputum eosinophil ratio and blood eosinophil count before treatment were collected through medical records. During the treatment of inhaled corticosteroids (ICS), the subjects were monitored at home for 4 weeks by FeNO analyzer and mobile electronic vital capacity at fixed time in the morning and evening. After the treatment, the above indicators were measured again to evaluate the treatment effect. Diurnal and dynamic changes of FeNO and pulmonary ventilation function monitored at home during treatment were analyzed. Results: The age of the subjects was (40±14) years, and 14 cases were female. After 4 weeks of ICS treatment, ACT score, mini-AQLQ score, forced expiratory volume at 1 second (FEV1, L) and FEV1/forced vital capacity (FVC, %) were 23±2, 5.49±1.04, 2.89±0.60 and 72.2±7.8, respectively, higher than before treatment [16±4, 4.06±0.95, 2.47±0.76 and 66.4±14.3, respectively]. FeNO [ppb (part per billion)], sputum eosinophil percentage (%) and blood eosinophil levels (×106/L) [M (Q1, Q3)] were 27 (18, 47), 2.8 (1.0, 14.0) and 255 (188, 280), respectively, lower than before treatment [80 (56, 117), 25.8 (15.0, 59.6) and 380 (283, 658)] (all P values<0.05). The level of FeNO in the morning was higher than that in the evening 2 weeks before routine monitoring (P=0.028), and no statistical difference was found in pulmonary ventilation function between day and night (P>0.05). The curve fitting of daily monitoring of FeNO and lung ventilation function showed that FeNO and lung ventilation function were gradually improved, and the effective time of treatment determined by FeNO was 3.5 (3.0, 5.3) d, which was earlier than all lung ventilation function indicators (all P values<0.05). The maximum action time of FeNO was (14.5±2.2) d, which was earlier than that of FEV1 (20.7±2.8) d (all P values<0.05), but there was no statistically difference between the maximum effect time determined by other lung ventilation function indicators (all P values>0.05). Conclusion: Household dynamic daily monitoring of FeNO and pulmonary ventilation function can be used to assess the response to ICS treatment, with FeNO being the more sensitive indicator.

Abstract
Airway inflammation is the most important pathological basis of chronic airway diseases. The detection and evaluation of airway inflammation is helpful for the diagnosis, treatment and management of airway diseases. Exhaled nitric oxide is the most widely used noninvasive airway inflammation detection technique in recent years, which provides a simple and quick reference for the diagnosis and management of chronic airway diseases, but there are still some controversies and deficiencies. This paper briefly expounds the biological significance of exhaled nitric oxide and detecting technique, summarizes the clinical application and the deficiencies of exhaled nitric oxide detection. In the future, with the further researchers on technology and the accumulation of application experiences, the detection technology of exhaled nitric oxide will play a more significant role in the accurate management of chronic airway diseases.

Abstract
Objective: To screen core differentially expressed genes of bronchial asthma and conduct bioinformatics analysis. Methods: Macrophage microarray data GSE22528 from asthma patients were downloaded from gene expression database (GEO). The dataset included transcriptome information from 10 human alveolar lavage fluid samples, and five of them were from allergic asthmatic subjects and five from control subjects. Differential expression genes (DEGs) were screened by R 4.0.4 software. Gene ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to select DEGs using DAVID 6.8 database. Protein interaction network (PPI) was constructed from DEGs encoded proteins using STRING online database. Cytoscape software was used to construct core modules and determine core DEGs. Results: Alveolar lavage fluid samples were all collected from Caucasian Canadians, with age range as (20, 37) and (18, 36) years, respectively, including 3 males for each group. In asthmatic patients, 449 genes were up-regulated and 47 down-regulated. GO analysis showed that the up-regulated genes in asthmatic patients were mainly involved in biological processes such as response to folded proteins, and the molecular function was focused on binding of folded proteins and growth factors. Down-regulated genes were mainly involved in biological processes such as histone deacetylation and ubiquitin-mediated protein degradation, and their molecular functions focused on histone deacetylation activity. KEGG pathway enrichment analysis showed that pathways were mainly enriched by up-regulation genes, involving Hippo signaling pathway, hypertrophic cardiomyopathy, estrogen signaling pathway, arrhythmogenic right ventricular cardiomyopathy, basal cell carcinoma, neuro-activated receptor ligand interaction, dilated cardiomyopathy and adhesion and connection signaling pathways. Two core modules were obtained by PPI analysis, and 14 core DEGs were screened out. They were pro-melanin concentrating hormone (PMCH), prepronociceptin (PNOC), Sphingosinol-1-phosphate receptor 2 (S1PR2), Sphingosinol-1-phosphate receptor 5 (S1PR5), CC-type chemokine ligand 21 (CCL21), Kelch-like protein 25 (KLHL25), ubiquitin binding enzyme E2V2 (UBE2V2), F-box protein 17 (FBXO17), taste receptor type 2 member 3 (TAS2R3), somatostatin receptor 2 (SSTR2), metabolic glutamate receptor 2 (GRM2), Lister E3 ubiquitin protein ligase 1 (LTN1), LIM domain specific protein 7 (LMO7) and ring finger protein 19A gene(RNF19A), in which LTN1 and UBE2V2 were down-regulated and the rest were up-regulated. Conclusion: DEGs was found in macrophages of asthmatic and control individuals. PMCH, PNOC, S1PR2, S1PR5 and CCL21 might be the core genes in the pathological process of asthma.

Abstract
Objective: To explore the effect of human bone marrow mesenchymal stem cells(MSC) on the steroid resistance of human airway epithelial cells. Methods: Ovalbumin (OVA)/lipopolysaccharide (LPS) were used to construct steroid resistant BEAS-2B cells, which were then co-cultured with MSC. Groups were set as follows: blank group, model group, Glucocorticoid group, MSC group, MSC+Glucocorticoid group (MSC+bud group). The expression of interleukin (IL)-8 in the cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA); the expression of reactive oxygen species (ROS) in the cells was detected by flow cytometry; the expression of glucocorticoid receptor α (GRα) and histone deacetylase 2 (HDAC2) protein in the cell was detected by Western blotting; and the expression of GRα and HDAC2 mRNA was detected by reverse transcription-polymerase chain reaction (RTPCR). Results: The expression level of IL-8 in the MSC group was significantly lower than that in the Glucocorticoid group (31.7±0.7 vs. 49.8±3.6, P<0.01). The expression of ROS in the MSC group was significantly lower than that in the Glucocorticoid group (2754±154 vs.4624±228, P<0.05). The expression level of HDAC2 mRNA in the MSC group was significantly higher than that in the Glucocorticoid group(1.749±0.005 vs. 1.283±0.098, P<0.05). The expression level of GRα mRNA in the MSC group was significantly higher than that in the Glucocorticoid group (1.623±0.079 vs.1.047±0.220, P<0.01). The expression of HDAC2 protein in the MSC group was significantly higher than that in the Glucocorticoid group (1.067±0.100 vs. 0.620±0.083, P<0.01). The expression of GRα protein in the MSC group was significantly higher than that in the Glucocorticoid group (0.834±0.053 vs. 0.579±0.017, P<0.01). ROS was positively correlated with the IL-8 expression (r=0.796, P<0.01) and negatively correlated with the HDAC2 and GRα mRNA expression (r=-0.893 3, P<0.01; r=0.931 4, P<0.01, respectively), as well as the HDAC2 and GRα Protein expression (r=-0.929 5, P<0.01;r=-0.864 3, P<0.01, respectively). Conclusions: Human MSC can improve steroid resistance of airway epithelial cells in an exocrine manner. The mechanism may be related to the down-regulation of ROS and up-regulation of HDAC2, which lead to GRα overexpression. In addition, MSC may improve the steroid resistance by reducing the expression of IL-8.

Abstract
Objective: To observe the efficacy and safety of Kangbingdu granules (KBD) in the treatment of influenza. Methods: A multicenter, randomized, double-blind, double-dummy, and positive-drug parallel control trial was conducted in 27 Grade ⅢA hospitals in China and the subjects were randomly assigned to the KBD test group or the oseltamivir phosphate capsule control group at a ratio of 1∶1. 200 subjects were planned to be enrolled in each group. The experimental group was given KBD (18g each time, 3 times a day) and oseltamivir phosphate simulator orally, while the control group was given oseltamivir phosphate capsule (75 mg each time, twice a day) and KBD simulator orally for 5 days. The primary efficacy indicators included the remission time of major clinical symptoms and the time of complete defervescence. The secondary efficacy indicators included dosage of acetaminophen, the change of traditional Chinese medicine (TCM) syndrome score and the remission time of other important clinical symptoms. The efficacy of KBD in the test group and Oseltamivir phosphate control group were compared. Adverse events or adverse reactions were observed at the same time to evaluate the safety of KBD Granules. Results: A total of 393 subjects from 27 Grade ⅢA hospitals in China were enrolled. The experimental group included 195 subjects and 191 subjects (97.95%) completed the trial, While the control group included 198 subjects and 195 subjects (98.48%) completed the trial. There was no significant difference in the shedding rate and rejection rate between the two groups (P>0.05). In the Full Analysis Set (FAS), the mean age of the experimental group was (34.9±14.4) years old, with 83 males (42.78%). The mean age of the control group was (33.3±13.5) years old, with 78 males (39.59%). There were no statistically significant differences between the two groups in demographic data, physical examination, viral pathogen detection, total score of TCM syndromes and scores of each symptom at baseline (P>0.05). In the FAS, the remission time M (Q1, Q3) of major clinical symptoms was 3.0 (3.0, 4.0) days in the experimental group and 3.0 (3.0, 4.0) days in the control group, and the difference was not statistically significant (P>0.05). The time M (Q1, Q3) of complete defervescence was 34.0 (20.3, 49.0) hours in the experimental group and 36.5 (19.6, 48.8) hours in the control group, and the difference was not statistically significant (P>0.05). KBD granules had the same effect as Oseltamivir phosphate capsule (P>0.05) in terms of acetaminophen dosage, TCM syndrome effect and disappearance rate of most important clinical symptoms. Meanwhile, the disappearance rate of dizziness and chest distress on day 3 in the KBD granules group was better than that of oseltamivir phosphate capsule (P<0.05). Conclusion: KBD granules have the same efficacy as Oseltamivir Phosphate capsule in the treatment of influenza and the drug safety is good.

Abstract
Objective: To assess the effectiveness of bronchial thermoplasty (BT) in "real-world" patients with severe asthma at 2 years post therapy. Method: Outcomes of 70 patients with severe asthma undergoing bronchial thermoplasty from March 2014 to November 2017 in China-Japan Friendship Hospital were retrospectively analyzed two years post therapy. The scores of Asthma Control Test (ACT) and Mini Asthma Quality of Life Questionnaire (mini-AQLQ), the number of severe exacerbations, emergency department visits and hospitalizations for asthma symptoms in the past year, indicators of pulmonary function including forced expiratory volume in one second (FEV(1)), FEV(1) as a percentage of predicted value (FEV(1)%pred) and FEV(1)/forced vital capacity (FEV(1)/FVC), maintenance asthma medications, the cost of asthma drugs and the total annual cost of asthma treatment were evaluated and analyzed before and 2 years after BT therapy, and the subjective assessment about effectiveness of BT were given by the patients. Results: Before and 2 years after BT, the numbers of subjects suffering severe exacerbations in the past year were 70 (100%) and 37 (52.9%), and the numbers of total severe exacerbations were 575 and 162 respectively. The numbers of patients having emergency department visits due to asthma exacerbation were 46 (65.7%) and 9 (12.9%), and the numbers of emergency department visits were 186 and 19 respectively. The numbers of patients hospitalized due to asthma exacerbation were 43 (61.4%) and 16 (22.9%), and the numbers of total hospitalizations were 124 and 24, respectively. The rate of severe exacerbation, emergency department visit and hospitalization were significantly reduced two years after the treatment by 71.9%, 88.9% and 83.3% (all P<0.001). The scores of ACT and mini-AQLQ were significantly increased [22 (21, 24) vs 17 (13, 19), (5.57±0.89) vs (3.83±0.92); both P<0.001]. Two years after BT, 4 patients (5.7%) were weaned off inhaled corticosteroids (ICS) and long-acting β(2)-agonist (LABA), while 14 patients (37.8%) were weaned off oral corticosteroid (OCS), with daily dose of ICS and OCS significantly decreased (both P<0.05). The proportion of patients treated with montelukast sodium and theophylline was also significantly reduced after BT (40.0% vs 81.4%, 27.1% vs 71.4%; both P<0.001). In addition, the indicator of FEV(1), FEV(1)%pred and FEV(1)/FVC ratio were all greatly improved two years after the treatment [2.27 (1.84, 2.82) vs 2.10 (1.70, 2.61) L, (76.8±19.5)% vs (72.5±19.8)%, (66.3±13.6)% vs (63.8±13.0)%; all P<0.05]. The annual cost for asthma drug and asthma treatment after BT were significantly decreased (P<0.001). Fifty-nine patients (84.3%) subjectively assessed the treatment as effective. Conclusion: The bronchial thermoplasty in "real-world" patients with severe asthma could significantly improve the asthma control, lung function and quality of life, and reduce severe exacerbations, emergency department visits and hospitalizations for asthma symptoms, while the maintenance asthma medications, the cost of asthma drugs and the total annual cost of asthma treatment are significantly decreased.

Abstract
Objective: To investigate the effects of bronchial thermoplasty (BT) on airway remodeling, asthma control and quality of life in patients with severe asthma. Methods: From January to September 2019, 11 patients with severe asthma were recruited from China Japan Friendship Hospital to receive BT treatment. The treatment was performed over three sessions separated by 3-week intervals. The right lower lobe, the left lower lobe and the bilateral upper lobes were treated respectively. In this study, patients' self-control method was used. The timepoint before the first BT treatment was defined as pre-treatment group, and the timepoint before the third treatment was defined as post-treatment group. Histological staining was used to detect the airway remodeling of the left lower lobe in two groups, including the mass of airway smooth muscle (ASM) and collagen in airway wall, and the thickness of basement membrane. The cell classification of bronchoalveolar lavage fluid (BALF) from the left lower lobe and peripheral blood, total serum IgE, asthma control test (ACT), mini asthma quality of life questionnaire (miniAQLQ) and the forced expiratory volume in 1 second expressed as percent predicted (FEV(1)%pred) were evaluated in the two groups. The correlation was analyzed between airway remodeling and asthma control and quality of life. Results: Effects of BT in post-treatment group, compared with pre-treatment group: the mass of ASM and collagen in airway wall was significantly decreased [(9.8±2.5)% vs (25.8±7.7)%, (12.9±4.0)% vs (17.4±5.6)%] (both P<0.05), while basement membrane thickness was not significantly different (P>0.05); the percentage of eosinophils in BALF and peripheral blood, and total serum IgE were not significantly different (all P>0.05); ACT score and miniAQLQ score were significantly increased [(23.1±1.8) vs (13.8±6.2) points, (5.3±1.3) vs (3.6±1.5) points] (both P<0.05), while FEV(1)% pred was not statistically different (P>0.05). The mass of ASM was negatively correlated with ACT score (r=-0.712), miniAQLQ score (r=-0.557) and FEV(1)%pred (r=-0.477), while the mass of collagen was negatively correlated with ACT score (r=-0.549) and miniAQLQ score (r=-0.639) (all P<0.05). Conclusion: BT treatment could improve airway remodeling, asthma control and quality of life in patients with severe asthma; besides, the reduction of remodeling is related to the improvements of asthma control and quality of life.

Abstract
Objective: To investigate the prevalence of asthma among the elderly people in China and to analyze the clinical features, self-management and cognitive level of elderly asthma patients. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the last epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) and seven regions (north, northeast, southern china, east, south, southwest and northwest) in China from February 2010 to August 2012. 2 034 were diagnosed as asthma. The elderly patients aged ≥65 years were selected from the 2 034 asthma patients. The clinical characteristics, comorbidities, the status of asthma control and self-management and insights of the disease in elderly asthma patients were analyzed. Results: Among the 2 034 asthma patients, 584 (28.7%) were elderly asthmatics aged ≥65 years old and 1 450 (71.3%) were<65 years old. In the elderly asthma group, Early-onset asthma accounted for 439 (75.2%) and 145 (24.8%) were late-onset. The common clinical manifestations of elderly asthma patients were: chest distress 395 (67.6%), wheezing 304 (52.1%), cough 298 (51.0%). Common comorbidities of elderly asthmatics were: chronic obstructive pulmonary disease 144 (24.7%), allergic rhinitis 122(20.9%), gastroesopheal reflux disease (GERD) 114(19.5%), allergic conjunctivitis 86 (14.7%), eczema 82 (14.0%), chronic bronchitis 76 (13.0%). The Asthma Control Test (ACT) scores of elderly asthmatics and non-elderly asthmatics were (18.5±3.2) and (21.7±3.4) respectively. There was a significant difference between the two groups (P=0.042). Of the elderly asthmatics, only 13 (2.2%) patients monitored daily using a peak flow meter. 93 (15.9%) patients aware that asthma was characterized by chronic airway inflammation. 64 (11.0%) asthmatics understood that the treatment goal. Conclusions: The clinical manifestations of elderly asthmatics are atypical, especially paroxysmal wheezing. Asthma in elderly people causes more comorbidities and mortality. The self-management and cognitive level of patients with asthma needs to be improved.

Abstract
Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of Coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

Abstract
Objective: To investigate the clinical characteristics and risk factors of severe bronchial asthma in Chinese people over 14 years old. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) located in seven regions (north, northeast, east, central China, south, southwest and northwest) of China from February 2010 to August 2012. A total of 2 034 were diagnosed as asthma. The clinical characteristics and related risk factors of patients with severe asthma in China were analyzed. Results: Among all asthma patients, 560 were newly diagnosed, accounting for 27.5% (560/2 034) and the percentage of previously confirmed patients was 72.5% (1 474/2 034). A total of 145 were eligible for severe asthma, accounting for 9.8% (145/1 474) of previously confirmed asthmatics and 7.1% (145/2 034) of all asthmatics. 83.5% (121/145) severe asthmatics had at least one trigger factor. Correlation analysis showed that the risk factors of severe asthma were: smoking (OR=1.543, 95%CI: 1.250-1.814), obesity (OR=2.186, 95%CI: 1.972-2.354), petting (OR=2.135, 95%CI: 1.904-2.283), combined with allergic rhinitis (OR=3.456, 95%CI: 2.721-4.326), gastroesophageal reflux disease (OR=1.842, 95%CI: 1.682-2.140), bronchiectasis (OR=1.665, 95%CI: 1.347-1.912) or chronic obstructive pulmonary disease (OR=1.312, 95%CI: 1.171-1.694). Conclusions: The most common comorbidities in severe asthmatics in China are allergic rhinitis and gastroesophageal reflux disease. The risk factors of severe asthma include obesity, allergic rhinitis, gastroesophageal reflux disease, chronic obstructive pulmonary disease, bronchiectasis, smoking and petting.

Abstract
Objective: To observe the effects of artesunate on airway responsiveness and airway inflammation in asthmatic mice. Methods: Thirty female BALB/c mice aged 6-8 weeks were randomly divided into control group, asthma group and artesunate group. In the asthma group and the artesunate group, the mice were sensitized by intraperitoneal injection of 20 μg of ovalbumin (OVA) and 0.2 ml of aluminum hydroxide suspension (2 mg) on day 0 and 14, respectively, and 1% OVA 10 ml dissolved in sterile phosphate (PBS) buffer was aerosolized for 30 min from the 21st to 28th day. The control group was sensitized with 0.2 ml of 2 mg suspension of aluminum hydroxide on day 0 and 14, and aerosolized by 10 ml of sterile PBS from the 21st to 28th day. Before the challenge, the artesunate group was intraperitoneally injected with 0.2 ml of artesunate. Artesunate was replaced with the same amount of normal saline in the control group and the asthma group. The mice were treated after 24 hours of last stimulation. The airway responsiveness of mice was measured by airway intubation and the changes of airway resistance and compliance were observed. Bronchoalveolar lavage fluid (BALF) was classified by cytology, and pathological changes of left lung tissue were observed and scored. Results: The airway resistance of the three groups increased and the lung compliance decreased with the increase of methacholine (Ach) concentration. The airway resistance and lung compliance of the three groups were different under the same concentration (P<0.05). The airway resistance of the artesunate group at Ach 6.25, 12.5, 25, 50, 100 mg/ml was lower than that of the asthma group at the same concentration [(1.01±0.48) vs (1.30±0.22), (1.06±0.44) vs (1.70±0.31), (1.30±0.64) vs (2.66±0.79), (1.82±0.55) vs (3.38±1.35), (2.49±0.85) vs (4.07±1.34) cmH(2)O·s(-1)·ml(-1)(1 cmH(2)O=0.098 kPa); t=3.862, 7.376, 9.113, 7.051, 6.685, all P<0.05]; the degree of lung compliance decrease at the concentration of Ach 3.125, 6.25, 12.5, 25, 50, 100 mg/ml was lower than that of the asthma group at the same concentration [(3.89±0.55)×10(-2) vs (3.07±0.63)×10(-2), (3.61±0.52)×10(-2) vs (3.04±0.58)×10(-2), (3.48±0.38)×10(-2) vs (2.78±0.57)×10(-2), (3.09±0.52)×10(-2) vs (1.73±0.62)×10(-2), (2.32±0.60)×10(-2) vs (1.29±0.54)×10(-2), (1.87±0.59)×10(-2) vs (1.15±0.44)×10(-2) ml/cmH(2)O; t=-6.295, -4.921, -6.533, -11.135, -8.48, -6.319, all P<0.05]. The proportion of eosinophils in artesunate group in BALF was significantly lower than that in asthma group [(16.63±8.58)% vs (40.44±12.94)%; t=4.336, P<0.05]. In the asthma group, the inflammatory cells infiltration of the bronchi and the perivascular area, the bronchial epithelial edema and degeneration can be observed, and the artesunate could reduce the infiltration of inflammatory cells around the bronchus and blood vessels, and the mucus secretion was also reduced in the artesunate group. Conclusion: Artesunate can improve airway hyperresponsiveness and airway inflammation in asthmatic mice and has a certain therapeutic effect on asthma.

Abstract
Objective: To investigate the distribution of airway inflammation phenotypes in patients with bronchial asthma and its correlation with asthma control level. Methods: Patients who met GINA 2017 asthma diagnostic criteria from October 2017 to April 2018 in respiratory outpatient department of China-Japan Friendship Hospital were included. The clinical data of non-acute asthma patients were prospectively collected, including general data, asthma control level, pulmonary function, induced sputum cell classification, serum total IgE, exhaled nitric oxide (FeNO), blood cell classification. The correlation between phenotype distribution of airway inflammation and airway inflammation markers (eosinophils in sputum, FeNO, blood eosinophil, serum IgE) and asthma control was analyzed by correlation analysis. The correlation between sputum eosinophil level and FeNO, blood eosinophil count, serum total IgE, forced expiratory volume in one-second (FEV(1)) predicted (FEV(1)%pred) was analyzed by correlation analysis too. Results: A total of 97 asthmatic patients were enrolled. There were 38 males (39.2%) and 59 females (60.8%), aged (48±14) (range 22 to 80). Control level of asthma:13 cases (13.4%) were controlled, 39 cases(40.2%) were partially controlled and 45 cases (46.4%) were uncontrolled. The phenotypes of airway inflammation were eosinophilic 51 cases (52.6%), neutrophilic 9 cases (9.3%), mixed 35 cases (36.1%) and paucigranulocytic 2 cases (2.1%). There was no significant correlation between airway inflammation phenotype distribution, airway inflammation markers and asthma control level (P>0.05). Sputum eosinophil level was positively correlated with FeNO level in controlled and uncontrolled patients (r=0.420, P=0.008 and r=0.325, P=0.031); sputum eosinophil level was positively correlated with blood eosinophil level in uncontrolled asthma patients (r=0.328, P=0.037). There was no significant correlation between sputum eosinophil level and FEV(1)%pred (P>0.05). Conclusions: Eosinophil type is the dominant type of airway inflammation in asthmatic patients, and there is no significant correlation between airway inflammation and asthma control level. At present, airway inflammation cannot be used to assess asthma control level.

Abstract
Objective: To improve the understanding of Eosinophilic granulomatosis with polyangiitis (EGPA). Methods: A total of 30 EGPA patients from the China-Japan Friendship Hospital between August 2005 and April 2017 were included, and a systematic retrospective study about clinical manifestations, laboratory findings, imaging features, pathology and so on was conducted. Results: There were 9 males and 21 females. Mean age was (44.5±13.9) years at diagnosis. Among these patients, 26 (86.7%) had asthma, duration was 45.0 (20.0, 78.7) months, and 15 (50.0%) had asthma as their first symptom. Rhinitis/nasosinusitis occurred in 27 (90.0%), skin lesions in 13 (43.3%), neuropathy in 10 (33.3%), heart disease in 8 (26.7%), renal involvement in 3 (10.0%) and gastro-intestinal manifestations in 3 (10.0%) of the patients. Peripheral blood eosinophil>10% accounted for 23/30 (76.7%). There were 3 patients (10.0%) who had positive anti-neutrophil antibody, and the pattern by immunofluorescence was mainly perinuclear. Migratory infiltrates often observed on the chest radiograph, and the main presentation was ground-glass opacity, amounting for 21/30 (70.0%). The pathological manifestations were extravascular eosinophilic tissue infiltration, necrotizing vasculitis, and extravascular granulomas, and the latter two of which were fewer. Conclusion: The manifestations of EGPA are individual, complex, with a lack of pathognomonic symptoms, and female predominated.

Abstract
The protective efficacy of litchi (Litchi chinensis Sonn.) flower proanthocyanidin fraction (LFPF) composed of (-)-epicatechin and proanthocyanidin A2 against vascular endothelial growth factor (VEGF) generation induced by nickel (Ni) in hepatocellular carcinoma (Hep G2) cells was studied. VEGF is an angiogenic inducer, which promotes tumor angiogenesis, leading to rapid tumor growth and metastasis. VEGF could be substantially induced in the Ni-mediated Hep G2 cells. Through LFPF treatment, the Ni-induced VEGF generation could be suppressed significantly. The inhibition of HIF-1α expression by blocking phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathways, and the suppression of Janus kinase 2 (JAK2)/signal transducers and activators of transcription 3 (STAT 3), and Raf-1 proto-oncogene, serine/threonine kinase (RAF1)/mitogen-activated protein kinase (MEK1/2)/extracellular-signal-regulated kinase (ERK1/2) pathways are important molecular mechanisms for the LFPF action. LFPF should probably reduce the risk of liver cancer in Ni-contaminated environments by inhibiting VEGF expression. PRACTICAL APPLICATIONS: LFPF mainly contained (-)-epicatechin and proanthocyanidin A2. Our results demonstrated that LFPF considerably suppressed the Ni-induced VEGF expression through inhibition of JAK2/STAT 3 and RAF1/MEK1/2/ERK1/2 pathways and prohibited HIF-1α expression through blocking PI3K/AKT/mTOR pathway. Litchi flowers might have the potential to diminish the liver cancer risk in a Ni-contaminated environment through suitable treatment.

Abstract
Objective: To understand the seasonal distribution of patient hospitalization due to asthma exacerbation in 7 geographic areas in China. Methods: This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout 7 geographic areas in the mainland of China (northeast, north, central, east, south, northwest and southwest). The numbers of asthmatic patients and total inpatients of the respiratory department of each hospital were recorded. The monthly ratio of asthmatic patients to the total inpatients in every area was calculated and compared. Results: During the study period, 6 480 patients were admitted for asthma exacerbation, accounting for 3.14% of all the 206 135 patients admitted to the respiratory departments in the 29 hospitals. The ratio of asthmatic patients to total inpatients in the northeast area (5.61%) was highest, and the ratio in east area was lowest (1.97%). Statistical analysis showed that the difference among different areas was significant (P<0.000 1). In most areas, both the number and proportion of hospitalized asthmatic patients peaked in spring (February-April) and autumn (September-October). In the northeast area, east area and south area, the peaks in spring were more obvious, while in the north area and southwest area, the peaks in autumn were more obvious. In the northwest area the peaks occurred in winter (December-January) and summer (June-August), respectively. The differences in hospitalization due to asthma among different months were significant in the northeast, north, and southwest areas (P<0.005). Conclusion: The number of patients hospitalized for asthma exacerbation fluctuated with season in different areas in China. In most areas, more asthmatic patients were admitted to hospitals in spring and autumn.

Abstract
Objective: To study the seasonal characteristics of patients hospitalized for asthma exacerbation in China. Methods: This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout mainland China during 2013-2014. The number of patients hospitalized for asthma exacerbation in each hospital was calculated, as well as the ratio of asthmatic patients to all the hospitalized patients. The analysis by month was conducted. The number and ratio of asthmatic patients in the northern and southern cities were calculated respectively. Results: During the study period, there were 6 480 patients hospitalized for asthma exacerbation, accounting for 3.14% (6 480/206 135) of all the hospitalized patients of the respiratory department in 29 hospitals. The analysis by month showed that the ratio of patients hospitalized for asthma exacerbation was highest in March (3.49%), then declined from April to June, then rose again from July, reaching a second peak at September (3.28%), and then declined again from October to December. The ratio of asthmatic patients in every month was higher in northern cities than in southern cities. Conclusions: The ratio of patients hospitalized for asthma exacerbation in China fluctuates with the changes of seasons, and March and September are the two peak months. Northern cities have a higher ratio of asthmatic patients than southern cities.

Abstract
Objective: To investigate warning symptoms of asthma attack and evaluate asthma self-management status of asthma patients in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out from 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of frequency and warning symptoms of asthma attack, the time from warning symptoms to asthma attack, the impact of asthma attack and asthma self-management were collected from asthma patients of outpatient department. Results: Altogether 3 875 asthmatic outpatients were recruited. 78.1% (3 026/3 875) of the patients reported restriction of exercise and daily activities during asthma exacerbation. 82.5% (3 160/3 829) of the patients had warning symptoms before asthma attack, the most common warning symptoms were cough, chest tightness and shortness of breath. The median time from warning symptoms to asthma attack was 2 h, the mean time was 90 h. Only 4.4% (167/3 829) of the patients had definite confidence to control asthma when symptoms deteriorated. 76.7% (2 937/3 828) of the patients used medications to control asthma when asthma symptoms deteriorated. Medication choice: inhaled corticosteroid (ICS) + formoterol 45.8% (1 776/3 875), short-acting beta-agonist (SABA) 23.9% (927/3 875). Conclusions: Most asthma patients have warning symptoms before asthma attack, the most common symptoms are cough, chest tightness and shortness of breath. The proportion of patients conducting effective asthma self-management remains low.

Abstract
Objective: To assess the overall asthma control level in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out in 30 provinces in China (except Tibet). Asthmatic outpatients who met the inclusion criteria were recruited consecutively from 30 sub-centers from October 2015 to May 2016. Data of demographic characteristics, asthma control, asthma management, asthma exacerbations and self-management, and disease perception were collected by face-to-face interviews. Results: Totally 3 875 asthmatic outpatients were recruited. Asthma control level was assessed according to GINA 2015. The prevalence of asthma control was 28.5%(1 099/3 854). Among 10 cities, which were also involved in the asthma control survey in 2008, the level of asthma control improved from 28.7% in 2008 to 39.2%(533/1 361) in 2016. The rate of hospitalizations due to asthma exacerbations was 26.4%(1 017/3 858) and the rate of emergency visits was 22.4%(864/3 858). Among adult patients, 18.4%(568/3 092) of them had been absent from work while 63.6%(63/99) adolescent patients had been absent from school because of asthma attacks in the previous year. Conclusion: Although the level of asthma control in China is still far from ideal at present, the status has been improved in some cities. Poorly controlled asthma resulted in increase of hospitalizations, emergency department visits and work/school absences.

Abstract
Objective: To study the characteristics of patients hospitalized for asthma exacerbation in 29 teaching hospitals in China and to evaluate the hospitalization costs of these patients. Methods: This was a retrospective study and involved patients hospitalized for asthma exacerbation in 29 hospitals throughout China during 2013-2014. Information about the demographic features, conditions before the admission, the outcome, the complications, and the costs was collected using the pre-designed case report form. The influencing factors of the hospitalization costs were analyzed. Results: 3 240 asthmatic patients (1 369 males and 1 871 females) were included and data were analyzed. There were 41.5% (1 346/3 240) patients who had a history of previous hospitalization or emergency department visits during the last year. Only 28.0% (907/3 240) patients had used asthma-controlling medications regularly before the admission. Seventy-three(2.3%) patients were admitted to ICU and used mechanical ventilation. Mortality among these patients hospitalized for asthma exacerbation was 0.25% (8/3 240). The median hospitalization costs was 9 045(6 431, 13 035) RMB. The costs of medications, examinations and treatment accounted for 52.1%, 27.6%, and 9.6% respectively. The costs of asthma medications accounted for only 22.7% of the total medication costs, while the costs of antibiotics accounted for 44.0%. The patients who were admitted to ICU, used mechanical ventilation, complicated with pneumonia, or had a history of hospitalization or emergency department visits during the last year due to asthma exacerbations tended to cost more. Conclusion: In this study, we demonstrated that only a minority of the patients had used asthma controllers regularly before the admissions with exacerbations. The in-hospital mortality of asthma patients in this study was much lower than that reported in other countries. The average cost of hospitalization was much higher than the yearly cost of maintenance therapy. Medication was the predominant component of the total hospitalization costs, and the costs of antibiotics made up the major part of the total medication costs.

Abstract
Objective: To study the treatment of patients hospitalized for asthma exacerbation in China. Methods: This was a retrospective study and involved patients hospitalized for asthma exacerbation in 29 hospitals throughout China during Jan 2013 to Dec 2014. Information of the demographic features, the severity of the exacerbation, the medicine prescribed during the hospitalization and the use of mechanical ventilation were collected and analyzed. Results: During the study period, there were 3 240 patients hospitalized for asthma exacerbation, and 1 369(42.3%) of them were males 1 871(57.7%)were females. Patients of mild, moderate, severe, and life-threatening exacerbation counted for 41.7%, 37.8%, 19.2% and 1.0%, respectively of the total patients. Of all the patients, 72.6% used bronchodilators by nebulizer, 70.8% used inhaled corticosteroids by nebulizer, 60.5% used intravenous corticosteroids, 17.3% used oral corticosteroids, and 80.5% used antibiotics. The percentages of patients using systemic corticosteroids and antibiotics were higher in patients with more severe exacerbation. In patients with mild exacerbation, there were 74.9% and 52.2% who used antibiotics and systemic corticosteroids, respectively. A total of 73 patients (2.3%) used mechanical ventilation, and 62 of them used noninvasive ventilation, 16 used invasive ventilation, and 5 used both. Conclusions: Nebulizer therapy has been accepted as the main administration route of medicine in the treatment of asthma exacerbation. A large amount of patients used antibiotics and systemic corticosteroids during hospitalization, indicating there may be some overuse of these medicines.

Abstract
Objective: In order to evaluate disease perception of asthma patients in urban China and provide evidence for further specific patient education. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out in 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of disease perception [Question 1: the disease nature of asthma; Question 2: medication choice of first-line in chronic asthma; Question 3: the occasion of using short-acting aerosols of receptor agonists; Question 4: perception of asthma treatment goal; Question 5: reason for not using peak flow meter (PFM)] were collected from asthma patients of outpatient department. These results were compared with the same type of survey results from 2007-2008. Results: Altogether 3 875 asthmatic outpatients were recruited. 69.0% (2 660/3 857) of the patients had right perception on the disease nature of asthma, 60.2% (2 321/3 857) of the patients considered inhaled corticosteroids (ICS)/inhaled corticosteroids plus long-acting beta2-agonists (ICS+ LABA) as daily-used first-line medication for chronic asthma. 85.7% (3 277/3 823) of the patients had right perception on the condition of using short-acting beta2-agonists (SABA). 75.4% (2 761/3 661) of the patients had right perception on asthma treatment goal. Only 10.1% (388/3 837) of the patients used PFM. Of the reasons for not using PFM, 65.2% (2 518/3 860) of the patients chose doctors never introduced. Among the 10 cities, which were also involved in the asthma control survey in 2007-2008, 71.1% (968/1 361) of the patients had right perception on the disease nature of asthma, 61.6% (839/1 362) of the patients considered ICS/ICS+ LABA as daily-used first-line medication for chronic asthma. 88.7% (1 207/1 361) of the patients had right perception on the condition of using SABA. 74.5% (1 013/1 360) of the patients had right perception on asthma treatment goal. 17.9% (244/1 360) of the patients used PFM. Of the reasons for not using PFM, 76.2% (931/1 221) of the patients chose doctors never introduced. Compared to the survey conducted in 2007-2008, the perception on disease nature and medication choice as daily-used first-line medication for chronic asthma significantly improved, the perception on occasion of using SABA and asthma treatment goal was comparable, while the rate of PFM usage showed no significant improvement. In reasons of not using PFM, doctors never introduced ranked the first. Conclusions: Compared to the similar survey conducted in 2007-2008, the overall status of disease perception of asthma patients has been improved in urban China, while the rate of PFM usage showed no significant improvement. Asthma education on asthma and asthma self-management should be further pushed forward.

Abstract
Objective: To study the mortality and death-related risk factors of patients hospitalized for asthma exacerbation in Chinese urban areas. Methods: A retrospective study was carried out in 29 hospitals of 29 provinces throughout mainland China. Patients hospitalized for asthma exacerbation during 2013-2014 in each hospital were included. For each patient, information about demography, admission time, comorbidities, severity of diseases, intense care unit (ICU) admission, use of mechanical ventilation and the outcome was obtained. The mortality of patients hospitalized for asthma exacerbation was calculated, and the basic information and causes of death of the patients who died were summarized. The death-related risk factors and numbers of comorbidities were compared between the patients who survived and those who died during hospitalization. Results: A total of 3 240 patients (median age 57.0) were included and among them 8 patients (median age 68.5) died. The mortality of patients hospitalized for asthma exacerbation was 0.25%. All the patients who died were admitted during the winter and spring. One patient died of acute myocardial infarction, one of cardiac shock, one of tension pneumothorax, one of sudden death, one of respiratory failure and three of unknown causes. The average number of comorbidities of patients who died was 1.10, larger than that of patients who survived (0.83) (P>0.05). More patients had diabetes, coronary artery diseases and hypertension as comorbidities in the patients who died (2/8) than those who survived[7.6% (246/3 232), 7.6% (246/3 232), 22.6% (731/3 232), respectively](all P>0.05). Conclusions: The in-hospital mortality of patients hospitalized for asthma exacerbation of China in this study is low. The patients who died are much older, and with more comorbidities, and a higher percentage of comorbidities such as diabetes, coronary artery diseases, and hypertension.

Abstract
Objective: To investigate the current perception of disease among asthmatic patients in Chinese urban areas, and to address its association with asthma control. Methods: This was a nationwide, multi-center, cross-sectional study covering 30 third-level, grade A hospitals in 30 provinces, municipalities and autonomous regions (not including Tibet) across Chinese mainland. The survey was carried out from October 2015 to May 2016. Asthmatic outpatients were selected to receive face-to-face questionnaire survey on asthma control including Asthma Control Test (ACT) score, classification of asthma control level[according to the Global Initiative for Asthma (GINA) 2015 classification system, as assessed by the physician completing the survey], perception of asthma (including question 1: nature of asthma as a disease; question 2: selection of first-line therapeutic agents to be regularly used daily for asthma; question 3: appropriate timing of the use of short-acting aerosols of β(2) receptor agonists; and question 4: therapeutic goals for asthma). Results: A total of 3 875 asthmatic outpatients were included; among them, 69.0% (2 660/3 857) were aware that asthma is "an airway inflammatory disorder resulting from the combined effects of heredity and environment" ; 60.2% (2 321/3 857) considered "inhaled glucocorticoids or their compound preparations" to be the first-line therapeutic agents to be regularly used daily for patients with persistent chronic asthma; 85.7% (3 277/3 823) considered it appropriate to use short-acting aerosols of β(2) receptor agonists "as needed in the event of disease aggravation or acute exacerbation" ; and 75.4% (2 761/3 661) were aware that asthma "can be adequately or completely controlled in the long term" . The ACT score[20 (16, 23) vs 19 (16, 22) points; Z=-3.928, P<0.001]and asthma control rate (29.92% vs 25.31%; χ(2)=8.616, P=0.003) were significantly higher, and the rate of uncontrolled asthma (19.92% vs 23.48%; χ(2)=6.267, P=0.012) was significantly lower among the 2 660 (69.0%) patients correctly answering question 1 than among the 1 197 (31.0%) patients giving incorrect answer. The ACT score[21 (17, 23) vs 19 (15, 22) points; Z=-9.190, P<0.001] and asthma control rate (32.66% vs 22.20%; χ(2)=49.614, P<0.001) were significantly higher, and the rate of uncontrolled asthma (18.40% vs 25.00%; χ(2)=24.267, P<0.001) was significantly lower among the 2 321 (60.2%) patient correctly answering question 2 than among the 1 536 (39.8%) patients giving incorrect answer. Conclusions: Compared to previous surveys, there has been improved perception of disease among asthmatic patients in Chinese urban areas. Correct perception of disease is favorable for improving asthma control level.

Abstract
Cyclea gracillima Diels is a Taiwanese native medicinal herb. However, there are currently few relevant reports on its biochemical activity. In this study, the antioxidant attributes of the ethanol and hot water extracts of this herb were assayed using in vitro models, including the following: 2,2-diphenyl-1-(2,4,6-trinitrophenyl)-hydrazyl radical scavenging, Trolox equivalent antioxidant capacity, reducing power, and chelating ferrous ions. The following biochemical models were also assayed: inhibition of human low density lipoprotein oxidation, inhibition of human erythrocyte hemolysis, and scavenging oxygen radicals in human blood. The composition and content of flavonoids and phenolic acids in these extracts were also analyzed. The results showed that these extracts with high polyphenol levels presented remarkable antioxidant effects in all assays, especially when extracted with ethanol. Six phenolic acids (mainly ferulic acid, sinapic acid, and syringic acid) and 12 flavonoids (mainly narigenin, myricetin, naringin, and apigenin) were found in these extracts.

Abstract
Objective: To study the relationship between bronchial asthma and smoking status in Chinese people. Methods: Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012. Asthma was diagnosed based upon case history, clinical signs and lung function test. Smoking status was investigated by questionnaire. Results: Sampling population was 180 099 and 164 215 were valid. A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women. The overall prevalence rate of asthma was 1.24% (2 034/164 215). Smokers were 23.8% (39 137/164 215) in the whole population. Smokers were 34.5% (702/2 034) in asthmatic patients, compared with 23.7% (38 435/162 181) in no-asthmatic population. The incidence of asthma was 1.79% and 1.06% in smokers and non-smokers respectively (P<0.001), suggesting that OR of smoking was 1.70 (95% CI 1.55-1.86, P<0.001). According to asthma control test (ACT) score, the level of asthma control in non smoking group was higher than that in smoking group(43.2% vs 35.3%). The times of hospitalization due to acute exacerbations(0.51 vs 0.41 events/person/year), total hospitalization rate(27.35% vs 20.12%), annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77% vs 24.47%) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients, indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients. Conclusions: The smoking rate in Chinese people over 14 years is still high. The prevalence rate of asthma in smokers is significantly higher than that of non-smokers. The level of asthma control in smokers is significantly worse than that in non smokers.

Abstract
Objective: To analyze the short-term (3 weeks) adverse respiratory events after bronchial thermoplasty(BT) in patients with severe asthma. Methods: The China-Japan Friendship Hospital recruited 62 patients with severe asthma for BT treatment from March 2014 to July 2016, with a total of 183 BT procedures. The data of adverse respiratory events within 3 weeks after procedure were collected to analyze the factors that might potentially influence the occurrence of adverse events. Results: Forty-three patients (69.4%) experienced adverse respiratory events within 3 weeks after treatment. Totally 153 adverse respiratory events occurred after 87 procedures(47.5%). The main adverse events were cough (15 events, 8.20%), sputum production (37 events, 20.22%), temporary PEF reduction (37 events, 20.22%), chest distress (12 events, 6.56%), blood in sputum (11 events, 6.01%), asthma exacerbation (10 events, 5.46%), and pneumonia(6 events, 3.28%). Most events were relieved or resolved with standard therapy in 1 week. No severe adverse events including tracheal intubation, malignant arrhythmias or death occurred within 3 weeks after procedure. The baseline eosinophil percentage in induced sputum and blood, operation times, and preoperative FEV(1) (% predicted) might influence the occurrence of adverse events after treatment. Patients with preoperative FEV(1) (% predicted) ≥60% had lower risk of adverse events. Conclusion: BT showed a good security profile in treating patients with severe asthma within 3 weeks after procedure.

Abstract
Important/potential value of macrolides has been proved in the management of chronic respiratory diseases by increasing basic and clinical trials.Through three face-to-face discussions, 10 experts examined important data and drafted this consensus related to macrolides: (1) mechanism of non-antiinfective effects; (2) clinical use in chronic respiratory diseases; (3) cautions of long-term use.The mechanism out of non-antiinfective effects includes anti-inflammatory effect, modifying airway secretion, immune-regulation related to antibacterial effect, corticoid saving effect and anti-viral effect.The efficacy of long-term use of low-dose macrolides is definitely confirmed in diffuse panbronchiolitis, chronic rhinosinusitis. It is considerably used in bronchiectasia, cystic fibrosis, severe asthma and chronic obstructive pulmonary disease. Further studies should be conducted in cryptogenic organizing pneumonia and respiratory viral infection. It should be paid attention to its possible adverse effects (including drug interactions, cardiac toxicity, ototoxicity and disturbance of intestinal flora) and drug resistance in long-term use.A Chinese consensus for non-antiinfective effects and clinical use of macrolides is developed for the first time, which aims to expand their rational use and the further research.

Abstract
Objective: To analyze the prevalence of severe asthmain China. Methods: The epidemiological data was collected from 2 034 asthmatics who were diagnosed in the last epidemiological survey from 2009 to 2010 in 8 provinces. Results: According to the questionnaire survey, among the 2 034 patients, the previously diagnosed patients accounted for 72.47% (1 474/2 034) and the percentage of newly-diagnosed patients was 27.53% (560/2 034). In those 1 474 previously diagnosed asthmatics, 122 (8.28%) were classified into severe asthma, while 6.00% (122/2 034) of all asthmatics and 0.07% (122/164 215) of total respondents presented as severe cases. Statistically, there was no difference in the prevalence of severe patients between men and women. The morbidity rate of severe asthma was the lowest in the 21-30 year old group and the highest in 61-70 year old group (0.85% and 8.31% respectively). The difference among ages was statistically significant (χ2=18.791, P=0.005). In addition, the prevalence rates of severe asthma were also significantly diverged among patients with different education background(χ2=24.639, P<0.000 1). A negative relation was found between education level and the proportion of severe cases. Moreover, the morbidity of severe asthma in smoking patients and non-smoking patients were significantly different as well (χ2=7.447, P<0.05). Compared with asthma patients who do not smoke, smokers were more likely to suffer severe asthma (OR=1.663, 95% CI 1.150-2.404). Conclusions: The prevalence rate of severe asthma in China is similar to that in other countries.Elderly patients have higher risk of severe asthma. Smoking is considered as a risk factor for severe asthma.

Abstract
OBJECTIVE To systematically estimate the regional distributions of invasive pneumococcal disease (IPD)'s serotypes in children of Chinese mainland. METHODS The literatures which described at least 20 strains of streptococcus pneumonia samples isolated from children with IPD in Chinese mainland were included in this study. Finally, 39 literatures met the inclusion criteria and were reviewed in this study. The average frequency of each serotype of streptococcus pneumonia was calculated and the uncertainty of each serotype range was described by 95% CI. RESULTS This study analyzed a total of 7 391 strains of streptococcus pneumoniae samples which mainly came from north China, east China, central China, south China and southwest regions of China. The results showed that the most common streptococcus pneumonia serotype causing IPD was 19F[30.05% (28.16%-31.98%)], and the second serotype was 23F[12.16% (10.00%-14.28%)], and the others were 19A[9.19% (7.01%-11.37%)], 6B[7.30% (5.09%-9.50%)], 14[7.02% (4.82%-9.23%)], 6A[6.08% (3.87%-8.30%)]and 15B[6.53% (2.88%-7.34%)]. CONCLUSION The most common streptococcus pneumoniae serotype is 19F, 23F, 19A, 6B, 14, 6A and 15B in Chinese Mainland.

Abstract
OBJECTIVE To explore the effects of artesunate on cigarette smoke-induced lung oxidative damage in mice and the expression of Nuclear factor-E2-related factor 2 (Nrf2). METHODS In vivo: A total of 40 female specific pathogen free BALB/c mice were divided randomly into four groups: normal group, cigarette smoke group, vehicle group and artesunate group. The latter three groups were exposed on cigarette smoke for 40 days. Vehicle (5% NaHCO3 containing 5% dimethyl sulfoxide, 0.1 ml of each mice) or artesunate (30 mg/kg, dissolved in the 0.1 ml vehicle) was given by intraperitoneal injections before each passive smoking of the vehicle or artesunate group. Saline of 0.1ml was given to the normal and cigarette smoke groups as negative controls. Cells in bronchoalveolar lavage fluid (BALF) were collected and analyzed by absolute different cell counts. Interleukin (IL)-8 levels in BALF and 3-nitrotyrosine (NT) levels in lung tissue were tested by emzyme linked immunosorbent assay (ELISA). Malondialdehyde levels in serum, total superoxide dismutase (SOD) activity and total glutathione peroxidase (GPx) activity in lung tissue were detected. The pathological changes of lung tissues were observed by HE staining. And the expression levels of Nrf2 were measured by Westernblotting. In vitro: 16HBE cells were cultured and transfected with Nrf2 siRNA. Cigarette smoke extract (CSE) were used to stimulate the secretion of IL-8 in cells. Cells were divided into five groups: blank group, non-transfected non-artesunate group, non-transfected artesunate group, transfected non-artesunate group and transfected artesunate group. The latter four groups were incubated with CSE, and non-transfected artesunate and transfected artesunate groups were intervened with artesunate (30 μmol/L) before CSE incubation. The IL-8 levels of each group were measured using ELISA kit. RESULTS In vivo: The total cell counts of BALF in artesunate group were significantly lower than the vehicle group [21.00(2.50)×10(4)/ml vs 35.50(2.50)×10(4)/ml, P<0.001], especially neutrophil counts [6.00(5.12)×10(4)/ml vs 13.60(5.25)×10(4)/ml, P<0.001]. The IL-8 levels in BALF, malondialdehyde levels in serum, 3-NT levels and total SOD activity in lung tissue of artesunate group were all drastically lower than those in the vehicle group [(508±55) vs (912±68) ng/L, (38.2±8.8) vs (48.7±10.6) μmol/L, (28.5±5.8) vs (50.0±9.7) μg/L and (11.8±1.8) vs (18.0±5.3) U/mg protein, respectively, all P<0.05]. No significant difference of total GPx activity existed in these four groups. And the expression level of Nrf2 in artesunate group significantly increased than that in vehicle group (P=0.008). In vitro: The IL-8 level of the non-transfected artesunate group was significantly lower than the non-transfected non-artesunate group [(352±26) vs (765±22) ng/L, P<0.001], while the IL-8 levels between the transfected artesunate and transfected non-artesunate groups had no significant difference. CONCLUSION Arteunate attenuates cigarette smoke-induced lung oxidative damage in mice and increases the expression level of Nrf2, and its effects might be mediated by the actions of nuclear Nrf2.

Abstract
We used a simple and efficient method to construct the bicistronic eukaryotic expression vector pIRES2-NGF-VEGF165. The nerve growth factor (NGF) gene was obtained from the genomic DNA of human peripheral blood mononuclear cells by polymerase chain reaction. The NGF cDNA fragment was inserted into the multiple cloning sites of the pIRES2-EGFP vector to generate the bicistronic eukaryotic expression plasmid pIRES2-NGF-EGFP. The vascular endothelial growth factor 165 (VEGF165) gene was obtained from the pIRES2-VEGF165-EGFP plasmid by polymerase chain reaction. Next, the VEGF165 cDNA fragment was cloned into pIRES2-NGF-EGFP in place of enhanced green fluorescent protein creating the plasmid pIRES2-NGF-VEGF165. pIRES2-NGF-VEGF165 was transfected into HEK293 cells and reverse transcription-polymerase chain reaction and Western blot analysis were used to test the co-expression of double genes. The NGF and VEGF165 genes were cloned and the DNA was sequenced, which revealed that NGF and VEGF165 were consistent with the sequence recorded in GenBank. Restriction analysis showed that the NGF and VEGF165 genes were inserted into the expression vector pIRES2-EGFP. Transfection of pIRES2-NGF-VEGF165 into HEK293 cells resulted in expression of the double gene at the mRNA and protein levels. The NGF and VEGF165 coexpression plasmid provides a novel expression system, enabling further study of the functions of the NGF and VEGF165 genes.

Abstract
We used a simple and efficient method to construct a bicistronic eukaryotic expression vector pIRES2-LIF-NT-3. The leukemia inhibitory factor (LIF) and neurotrophin-3 (NT-3) genes were obtained from the genomic DNA of human peripheral blood mononuclear cells by polymerase chain reaction. The LIF cDNA fragment was inserted into the multiple cloning sites of a vector containing internal ribosome entry site and enhanced green fluorescent protein (EGFP) (pIRES2-EGFP) to generate the bicistronic eukaryotic expression plasmid pIRES2-LIF-EGFP. Next, the NT-3 cDNA fragment was cloned into pIRES2-LIF-EGFP in place of EGFP to create the plasmid pIRES2-LIF-NT-3. pIRES2-LIF-NT-3 was transfected into HEK293 cells and reverse transcription-polymerase chain reaction and Western blotting were used to test the co-expression of double genes. LIF and NT-3 genes were cloned and the DNA was sequenced. Sequencing analysis revealed that LIF and NT-3 were consistent with the sequence recorded in GenBank. Restriction analysis indicated that the LIF and NT-3 genes were inserted correctly into the expression vector pIRES2-EGFP. Following transfection of pIRES2-LIF-NT-3 into HEK293 cells, the double gene was expressed at the mRNA and protein levels. The LIF and NT-3 coexpression plasmid is a novel expression system that will enable further study of the functions of the LIF and NT-3 genes.

Abstract
Litchi (Litchi chinensis Sonn.) flower ethanolic extract (LFEE) was found to contain five flavanoids [total amount, 102.73 ± 5.50 mg/g of dried extract (gDE)], nine phenolic acids (total amount, 60.31 ± 4.52 mg/gDE), and proanthocyanidin A2 (79.31 ± 2.95 mg/gDE). LFEE was used to evaluate the inhibitory effects on lipopolysaccharide- (LPS-) induced pro-inflammatory mediators in RAW264.7 cells. The results showed that LFEE treatment could suppress the expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the productions of nitric oxide (NO) and prostaglandin E2 (PGE2), and the secretions of pro-inflammatory cytokines [interleukin-1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α)] in the LPS-mediated RAW264.7 cells. The attenuation of LPS-induced inflammatory responses by LFEE was found to be closely related to the inhibition of the translocation of nuclear factor κB (NF-κB) p50/p65 subunits correlated with suppression of the activation of the inhibitor of κB kinase (IKK) α/β and downregulation of activation of extracellular signal-regulated kinase (ERK) and Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3).

Abstract
To investigate the variance of exogenous gene expression driven by different promoters by in vivo electroporation, 3 plasmid vectors carrying different promoters were selected, and their driving strength was compared in developing chicken embryos. The 3 promoters included: 1) the CAG promoter (containing the cytomegalovirus (CMV) immediate early enhancer and the chicken β-actin promoter), 2) the CMV promoter (the human CMV immediate early region enhancer), and 3) the SV40 promoter (Simian virus 40). The intensity of GFP expression driven by the 3 promoters was detected by fluorescence microscopy. The results clearly showed that the expression intensity of the reporter gene differed significantly among the 3 promoters. Chicken β-actin promoter induced the highest intensity of GFP expression, while SV40 promoter induced the lowest intensity. Our results indicate that plasmids with appropriate promoters should be carefully selected to obtain strong exogenous gene expression by in vivo electroporation.

Abstract
Protocadherins constitute a large family belonging to the cadherin superfamily; they function in various tissues of a wide variety of multicellular organisms. However, their functions and expression modes are still unknown in many of these species and tissues. We developed a fast and low-cost method to produce polyclonal antibody against chicken protocadherin 1 (Pcdh1) that could be used in assays for immunological assessment of protein expression levels of chicken Pcdh1. Primers were designed with DNAStar, using the nuclear sequence of pcdh1 as a template; the pcdh101 fragment was amplified, identified by sequencing and cloned into expression vectors pGEX-2TK and pET-32a, separately, resulting in 2 recombinant plasmids, pGEX-2TK-pcdh101 and pET-32a-pcdh101. These were confirmed by double-enzyme digestion and sequencing. The recombinant expression vectors were transformed and expressed in Escherichia coli BL21. The recombinant oligopeptides glutathione-S-transferase (GST)-Pcdh101 and (His)6-Pcdh101 fused with the carrier protein GST and (His)6 separately, and were purified. Rats were immunized by injecting the emulsified GST-Pcdh101 antigen subcutaneously into their hind footpads, followed by a booster injection after 2 weeks. One week after the booster, the sera were collected and examined for antibody titer by indirect ELISA. The optimal dilution of this antiserum was 1:300. The specificity of the antiserum was confirmed by Western blotting. This antiserum had good specificity and could be used to detect chicken Pcdh1 in Western blot analysis. This method allows production of specific rat polyclonal antisera for Western blots in less than 1 month at a relatively low cost.
