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.

J Med Internet Res 2020; 22:e16322. [PMID: 33337340 PMCID: PMC7775818 DOI: 10.2196/16322] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 07/03/2020] [Accepted: 11/11/2020] [Indexed: 11/13/2022] Open
Abstract
Background Mobile health apps have emerged as useful tools for patients and clinicians alike, sharing health information or assisting in clinical decision-making. Prostate cancer (PCa) risk calculator mobile apps have been introduced to assess risks of PCa and high-grade PCa (Gleason score ≥7). The Rotterdam Prostate Cancer Risk Calculator and Coral–Prostate Cancer Nomogram Calculator apps were developed from the 2 most-studied PCa risk calculators, the European Randomized Study of Screening for Prostate Cancer (ERSPC) and the North American Prostate Cancer Prevention Trial (PCPT) risk calculators, respectively. A systematic review has indicated that the Rotterdam and Coral apps perform best during the prebiopsy stage. However, the epidemiology of PCa varies among different populations, and therefore, the applicability of these apps in a Taiwanese population needs to be evaluated. This study is the first to validate the PCa risk calculator apps with both biopsy and prostatectomy cohorts in Taiwan. Objective The study’s objective is to validate the PCa risk calculator apps using a Taiwanese cohort of patients. Additionally, we aim to utilize postprostatectomy pathology outcomes to assess the accuracy of both apps with regard to high-grade PCa. Methods All male patients who had undergone transrectal ultrasound prostate biopsies in a single Taiwanese tertiary medical center from 2012 to 2018 were identified retrospectively. The probabilities of PCa and high-grade PCa were calculated utilizing the Rotterdam and Coral apps, and compared with biopsy and prostatectomy results. Calibration was graphically evaluated with the Hosmer-Lemeshow goodness-of-fit test. Discrimination was analyzed utilizing the area under the receiver operating characteristic curve (AUC). Decision curve analysis was performed for clinical utility. Results Of 1134 patients, 246 (21.7%) were diagnosed with PCa; of these 246 patients, 155 (63%) had high-grade PCa, according to the biopsy results. After confirmation with prostatectomy pathological outcomes, 47.2% (25/53) of patients were upgraded to high-grade PCa, and 1.2% (1/84) of patients were downgraded to low-grade PCa. Only the Rotterdam app demonstrated good calibration for detecting high-grade PCa in the biopsy cohort. The discriminative ability for both PCa (AUC: 0.779 vs 0.687; DeLong’s method: P<.001) and high-grade PCa (AUC: 0.862 vs 0.758; P<.001) was significantly better for the Rotterdam app. In the prostatectomy cohort, there was no significant difference between both apps (AUC: 0.857 vs 0.777; P=.128). Conclusions The Rotterdam and Coral apps can be applied to the Taiwanese cohort with accuracy. The Rotterdam app outperformed the Coral app in the prediction of PCa and high-grade PCa. Despite the small size of the prostatectomy cohort, both apps, to some extent, demonstrated the predictive capacity for true high-grade PCa, confirmed by the whole prostate specimen. Following our external validation, the Rotterdam app might be a good alternative to help detect PCa and high-grade PCa for Taiwanese men.

Abstract
Mammalian STE20-like kinase 1 (MST1/STK4/KRS2) encodes a serine/threonine kinase that is the mammalian homolog of Drosophila Hippo. STK4 plays an important role in controlling cell growth, apoptosis, and organ size. STK4 has been studied in many cancers with previous studies indicating an involvement in colon cancer lymph node metastasis and highlighting its potential as a diagnostic marker for colon cancer. However, the role of STK4 defect in promoting colon cancer progression is still understudied. Here, we found that STK4 was significantly downregulated in colon cancer and was associated with distal metastasis and poor survival. Furthermore, STK4 knockdown enhanced sphere formation and metastasis in vitro and promoted tumor development in vivo. We found that STK4 colocalized with β-catenin and directly phosphorylated β-catenin resulting in its degradation via the ubiquitin-mediated pathway. This may suggest that STK4 knockdown causes β-catenin phosphorylation failure and subsequently β-catenin accumulation, consequently leading to anchorage-independent growth and metastasis in colon cancer. Our results support that STK4 may act as a potential candidate for the assessment of β-catenin-mediated colon cancer prognosis.

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
PURPOSE To develop a novel Taiwanese prostate cancer (PCa) risk model for predicting PCa, comparing its predictive performance with that of two well-established PCa risk calculator apps. METHODS 1545 men undergoing prostate biopsies in a Taiwanese tertiary medical center between 2012 and 2019 were identified retrospectively. A five-fold cross-validated logistic regression risk model was created to calculate the probabilities of PCa and high-grade PCa (Gleason score ≧ 7), to compare those of the Rotterdam and Coral apps. Discrimination was analyzed using the area under the receiver operator characteristic curve (AUC). Calibration was graphically evaluated with the goodness-of-fit test. Decision-curve analysis was performed for clinical utility. At different risk thresholds to biopsy, the proportion of biopsies saved versus low- and high-grade PCa missed were presented. RESULTS Overall, 278/1309 (21.2%) patients were diagnosed with PCa, and 181 out of 278 (65.1%) patients had high-grade PCa. Both our model and the Rotterdam app demonstrated better discriminative ability than the Coral app for detection of PCa (AUC: 0.795 vs 0.792 vs 0.697, DeLong's method: P < 0.001) and high-grade PCa (AUC: 0.869 vs 0.873 vs 0.767, P < 0.001). Using a ≥ 10% risk threshold for high-grade PCa to biopsy, our model could save 67.2% of total biopsies; among these saved biopsies, only 3.4% high-grade PCa would be missed. CONCLUSION Our new logistic regression model, similar to the Rotterdam app, outperformed the Coral app in the prediction of PCa and high-grade PCa. Additionally, our model could save unnecessary biopsies and avoid missing clinically significant PCa in the Taiwanese population.

Abstract
Muscle-invasive urinary bladder urothelial carcinoma (UBUC) is a lethal disease for which effective prognostic markers and potential therapy targets are still lacking. Previous array comparative genomic hybridization identified that 3q27 is frequently amplified in muscle-invasive UBUCs, one candidate proto-oncogene, B-cell CLL/lymphoma 6 (BCL6), mapped to this region. We therefore aimed to explore its downstream targets and physiological roles in UBUC progression. Methods: Specimens from UBUC patients, NOD/SCID mice and several UBUC-derived cell lines were used to perform quantitative RT-PCR, fluorescence in situ hybridization immunohistochemistry, xenograft, gene stable overexpression/knockdown and a series of in vitro experiments. Results: Amplification of the BCL6 gene lead to upregulation of BCL6 mRNA and protein levels in a substantial set of advanced UBUCs. High BCL6 protein level significantly predicted poor disease-specific and metastasis-free survivals. Knockdown of the BCL6 gene in J82 cells inhibited tumor growth and enhanced apoptosis in the NOD/SCID xenograft model. In vitro experiments demonstrated that BCL6 inhibited cytostasis, induced cell migration, invasion along with alteration of the expression levels of several related regulators. At molecular level, BCL6 inhibited forkhead box O3 (FOXO3) transcription, subsequent translation and upregulation of phosphorylated/inactive FOXO3 through phosphoinositide 3-kinase (PI3K)/AKT serine/threonine kinase (AKT) and/or epidermal growth factor receptor (EGFR)/mitogen-activated protein kinase 1/2 (MAP2K1/2) signaling pathway(s). Two BCL6 binding sites on the proximal promoter region of the FOXO3 gene were confirmed. Conclusion: Overexpression of BCL6 served a poor prognostic factor in UBUC patients. In vivo and in vitro studies suggested that BCL6 functions as an oncogene through direct transrepression of the FOXO3 gene, downregulation and phosphorylation of the FOXO3 protein.

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 objective of this study was to examine the expression level of cytochrome P450 4B1 (CYP4B1) protein and its clinical significance in specimens from patients with urothelial carcinomas (UC) including upper tract urothelial carcinoma (UTUC, n = 340) and urinary bladder urothelial carcinoma (UBUC, n = 295). Data mining on public domains identified five potential candidate transcripts which were downregulated in advanced UBUCs, indicating that it might implicate in UC progression. Immunohistochemistry was performed to analyze the CYP4B1 protein levels on 635 tissues from UC patients retrospectively. Immunoexpression of CYP4B1 was further estimated using the H-score method. Correlations between CYP4B1 H-score and important clinicopathological factors, as well as the significance of CYP4B1 expression level for disease-specific and metastasis-free survivals were evaluated. In UTUCs and UBUCs, 118 (34.7%) and 92 (31.2%) patients, respectively, were identified to be of CYP4B1 downregulation. The CYP4B1 expression level was found to be associated with several clinicopathological factors and patient survivals. Downregulation of CYP4B1 protein was correlated to advanced primary tumor (p < 0.001), nodal metastasis (p < 0.001), high histological grade (p = 0.001), vascular invasion (p < 0.001), perineural invasion (p = 0.017) and mitotic rate (p = 0.036) in UTUCs and/or UBUCs. Low CYP4B1 protein level independently predicted inferior disease-specific (p = 0.009; p < 0.001) and metastasis-free (p = 0.035; p < 0.001) survivals in UTUC and UBUC patients. Our findings showed that downregulation of CYP4B1 protein level is an independent unfavorable prognosticator. Loss of the CYP4B1 gene expression may play an important role in UC progression.

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.
