Progress in Gasdermin B gene and its related diseases / 中华微生物学和免疫学杂志

Human Gasdermin B (GSDMB) gene, as a member of the Gasdermin (GSDM) gene family, may be associated with the development of asthma, tumor and immune system diseases. Recent studies have found that cell pyroptosis can be mediated by GSDMB protein. The N-terminus of GSDMB cleaved by Granzyme A (GZMA), which is secreted by cytotoxic lymphocytes, can directly promote cell pyroptosis. Moreover, GSDMB protein promotes the cleavage of Gasdermin D (GSDMD) by binding to cysteinyl aspartate specific proteinase-4 (caspase-4), thus indirectly promoting cell pyroptosis. This article summarized the progress in the mechanism of GSDMB gene-mediated cell pyroptosis and the related diseases.

Research progress on the anti-inflammatory effect of interleukin 37 and its role in asthma / 中华微生物学和免疫学杂志

IL-37 is a member of the IL-1 family of cytokines, which functions as a natural suppressor of inflammatory and immune responses. IL-37 likely functions to limit excessive inflammation, accordingly, IL-37 levels are abnormal in patients with inflammatory and autoimmune diseases. In this review, we provide an overview of the anti-inflammatory mechanism of IL-37. It also summarizes the research progress of expression and its role in bronchial asthma, a heterogeneous chronic airway inflammatory disease.

Hospitalization Due to Asthma Exacerbation: A China Asthma Research Network (CARN) Retrospective Study in 29 Provinces Across Mainland China

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Experts consensus for the diagnosis, treatment, and prevention of coronavirus disease 2019 in the elderly / 中华内科杂志

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.

Add-on Tiotropium in Chinese Patients With Moderate Asthma: A Pooled Subgroup Analysis of MezzoTinA-Asthma 1 and 2

PURPOSE: Asthma affects approximately 30 million patients in China; however, tiotropium data for Chinese patients is limited. This study aimed to assess the efficacy and safety of tiotropium in Chinese patients with moderate symptomatic asthma. METHODS: A post hoc subgroup analysis was conducted on 430 Chinese patients pooled from two 24-week, replicate phase 3 trials (NCT01172808 and NCT01172821), in which they received once-daily tiotropium 2.5 µg (Tio R2.5) or 5 µg (Tio R5) (n = 106 or 109, respectively), twice-daily salmeterol 50 µg (Sal 50) (n = 110), or placebo (n = 105), while maintaining inhaled corticosteroids (ICS). The co-primary endpoints assessed in week 24 were forced expiratory volume in 1 second (FEV1) peak0–3h response, trough FEV1 response, and responder rate as assessed using the Asthma Control Questionnaire (ACQ). RESULTS: For both FEV1 peak0–3h responses and trough FEV1 responses, the mean treatment differences were greater for Tio R2.5, Tio R5, and Sal 50 compared with placebo at 0.249 L, 0.234 L, and 0.284 L, and 0.172 L, 0.180 L, and 0.164 L, respectively (P< 0.001). The ACQ responder rate in placebo, Tio R2.5, Tio R5, and Sal 50 was 58.7%, 62.3%, 59.3%, and 69.1%, respectively. Furthermore, 11 (2.6%) of 430 patients had serious adverse events (Tio R5, n = 4; Tio R2.5, n = 1; Sal 50, n = 1; and placebo, n = 5). CONCLUSIONS: Once-daily tiotropium, as add-on to medium-dose ICS, was effective and well tolerated for Chinese patients with moderate symptomatic asthma, consistent with the main analysis.

Evaluation of asthma management from the surveys in 30 provinces of China in 2015-2016 / 中华内科杂志

Objective To evaluate the general level of asthma management in urban areas of China and further promote the national asthma management plan. Methods A multi-center, cross-sectional survey was carried out in 30 provinces of China (except for Tibet) during Oct 2015 to May 2016. It's a questionnaire-based face-to-face survey which included asthma management using peak flow meter (PFM) and pulmonary function test,medication choice of maintenance therapy and asthma education.Results A total of 3 875 asthmatic outpatients were recruited including 2 347(60.6%)females and 1 528(39.4%)males. The mean age was(50.7±16.7)years ranging from 14 to 99.Only 10.1%(388/3 837)patients used PFM as monitoring, whereas 62.1%(2 405/3 874) patients underwent pulmonary function test during the past year. There were 57.4%(2 226/3 875) patients treated with inhaled cortical steroid plus long-acting β2-agonist combinations (ICS+LABA) as daily medication. 43.3%(1 661/3 836) patients were followed up by physicians. Among this population, 1 362 asthmatic outpatients were recruited, who also took part in the asthma control survey in 2007-2008 in 10 cities.In this subgroup,17.9%(244/1 360)were tested by PFM and 66.6%(907/1 362)by pulmonary function test during last year.As to the medication,63.1%(860/1 362) selected ICS+LABA for daily control. There were 50.4%(685/1 359) patients in the follow-up cohort by physicians.Compared to the similar survey conducted in 2007-2008,the proportion of patients with ICS+LABA regimen and follow-up by physicians were markedly higher,while the rate of PFM use did not have significant improvement. Conclusion Although the present level of asthma management in China is still far from ideal, asthma management has improved compared to 8 years ago. Yet the use of PFM does not significantly improve.Asthma action plan and application of PFM should be further promoted to improve the level of asthma management.

A retrospective study of the inducing factors and clinical characteristics of patients hospitalized for asthma exacerbation in China in 2013-2014 / 中华内科杂志

Objective To study the inducing factors and clinical characteristics of patients hospitalized for asthma exacerbation in China. Methods Patients hospitalized for asthma exacerbation at 29 hospitals in China were retrospectively recruited during 2013-2014. Results Clinical data of 3 240 asthmatic patients were collected and analyzed including 1 369(42.3%) males and 1 871(57.7%)females. The patients hospitalized for asthma exacerbation counted for 2.95% (6 375/215 955) of all patients hospitalized during the same period. The leading six inducing factors, in sequence, were acute upper respiratory tract infection[42.3%(1 370/3 240)],changes of weather[22.8%(738/3 240)],noxious gas[(4.3% (140/3 240), allergy challenges [3.5%(115/3 240)], strenuous exercise [1.8%(57/3 240)], and air pollution [1.5%(49/3 240)].In older patients,more exacerbations were induced by weather changes,yet less sensitive to allergy challenges. As to middle-aged patients, they were less sensitive to upper respiratory tract infections,however the difference was not statistically significant(P>0.05).In winter more asthma patients were induced by upper respiratory tract infections,while in autumn more patients were induced by weather changes,strenuous exercise and air pollution.In spring and summer more patients were induced by allergy challenges, but the differences failed to achieve statistical significance (P>0.05). In northern cities more patients were induced by upper respiratory infections, whereas in southern cities more by noxious gases. Allergy challenges and air pollution tended to affect more patients in northern cities,but the difference was of no significance (P>0.05). The differences of inducing factors among patients of different gender, with or without a smoking history, and with different exacerbation severity didn't show any statistical significance. The patients with severe and life-threatening exacerbations counted for 20.1%(652/3 240).The percentage of patients older than 60 years was higher in patients with severe or life-threatening exacerbations than in whose with mild or moderate exacerbations,so did the percentage of male patients,of patients with disease duration longer than 10 years, with smoking history, and with a history of hospitalization or emergency department visits due to asthma exacerbation during the last year.Conclusion The acute upper respiratory tract infection ranks top among all the inducing factors. Senility, male gender, long duration of disease, smoking history, and a history of frequent hospital visits might be the risk factors for severe or life-threatening asthma exacerbations.

Seasonal distribution of patient hospitalization due to asthma exacerbation in 7 geographic areas in China / 中华流行病学杂志

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.

The relationship between smoking status and epidermiology of asthma in people aged over 14 years in China / 中华内科杂志

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 nonsmokers 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.

Chinese expert consensus for non-antiinfective effects and clinical use of macrolides / 中华内科杂志

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 nonantiinfective 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.

Dynamic monitoring of the neutrophil/lymphocyte ratio could predict the prognosis of patients with ;bloodstream infection / 中华危重病急救医学

Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.

A survey of knowledge on common cold and its treatment situation among physicians from various levels of hospitals in mainland China / 中华内科杂志

Objective To investigate the cognition of the common cold and current situation of the treatment among physicians from various levels of hospitals in Chinese mainland,so as to provide evidence for future continuing medical education and rational medication.Methods A questionnaire designed for this survey was used to learn about the general information,cognitive degree of the common cold and prescription habits of physician who prescribed for cold within last three months,from various levels hospitals.Results A total of 1001 physicians were interviewed.Among them,749 physicians chose right options that the cold was the common cold and the influenza with 79.84％ in resident physicians and 56.76％ in chief physicians.A total of 745 physicians chose options that the course of common cold will be lasting 4 to 7 days; 895 physicians chose options that old people are the most susceptible for complication; 669 physicians thought the common cold was the most common infection in winter; 841 physicians used clinical methods to diagnose the common cold; 736 physicians thought although the cold was a kind of self-limited disease and symptomatic treatment could alleviate symptoms and improve life quality,patients should see doctor in time if it turns to severer; and 745 physicians held the opinion that treatment of the common cold should focus on relieving symptoms first. In addition, 61.60％ physicians had made prescription based on clinical symptoms; 505(54.24％ ) of them thought compound drugs were priority in treating the common cold.However,there were still 43 physicians prescribed antibiotics for common cold.Conclusions There is misunderstanding and discrepancy in cognition towards common cold and treatment among physicians from various levels of hospticals in mainland China.Physicians should standardize diagnosis and treatment for the common cold according to the domestic and foreign guidelines.

A survey of knowledge on common cold in outpatient clinics / 中华内科杂志

Objective To investigate outpatients' cognition towards common cold and their habituated medication so as to provide evidence for future public healthcare education.Methods Patients who attended hospital for diagnosis and treatment of common cold at least within past three months were asked to fill a questionnaire independently so as to learn their cognition towards common cold and medication habit.Results Among the patients underwent survey,52.2 ％ had incorrect knowledge about common cold; 2.99％ didn't know about the hazards of common cold; 34.80％ couldn't distinguish common cold from influenza; 30.07％ considered common cold couldn't get relief without treatment; 68.24％ didn't know about the proper effects of influenza vaccination; 6.4％ often took oral medicine even intravenous injection when they caught a common cold; 59.77％ often took medication from drugstore without prescription by doctor,and a few asked doctors to prescribe medicine on their request; 9.42％ didn't know about the side effects of drug for cold treatment; and 9.72％ didn't know about the active ingredients of drug for cold treatment.There were significant differences in the common cold cognition among population of different ages and education background.The older or the higher education status patients had a better cognition ( P ＜0.0 ).Conclusion There exist a certain degree of wrong cognition towards common cold among patients of different literacy degree and different age. Public health education on common cold need to be further strengthened.

The analysis for the degree of the asthmatic patients' understanding of the disease / 中华健康管理学杂志

Objective To learn the degree of the asthmatic patients'understanding of the disease, and to provide references for formulating the plan of the asthma patient's education and management infuture.Methods One hundred and one outpatients were surveyed by questionnaire face to face.Results Among 101 patients,the percentages of mild intermittent,mild persistent,moderate persistent and severepersistent asthma assessed by current symptom were 23%,29%,30%,18%.Among these patients thosewho understanding the inflammatory nature of asthma account occupied 70.3%,those who realizing the importance of inhaled corticosteroids(ICS)and taking ICS as the first-line medicine for asthma occupied67.3%,those who knowing the indication about rational use of short-acting beta-2-agonists(SABA)occupied 88.1%,those who realizing the goal of asthmatic therapy occupied 71.3%.All these results were significantly better than both the reporter in the asthma insights and reality in Asia-Pacific and the realizing degree to asthma of the respiratory professionals in Beijing's urban district hospitals in 1997.Conclusion After long term systematic education and management,asthmatic patient's understanding of the disease has been improved greatly.

Impact of "three-in-one" asthma education and management model on asthma control in adult patients / 中华内科杂志

Objective To evaluate the impact of the asthma education and management model developed by Peking University People's Hospital on the level of asthma control. Methods Trained respiratory physicians from 6 large teaching hospitals in the urban districts of Beijing conducted a successive questionnaire survey in the form of face-to-face interviews with adult asthma patients attending their respective clinics. The results were used to compare the levels of asthma control between patients who were administered "three-in-one" asthma education and management (education group) and those who were not(control group). Results Among the 100 patients in the education group, 85% showed asthma control test(ACT) values ≥20 points. This was significantly higher than that in the 427 control group patients (37%,χ2 =74.345 ,P <0.01 ). During the past 1 year, the rate of hospitalization due to exacerbation of asthma,number of emergency treatments, and missed working days were significantly lower in the education group than in the control group ( 4%, 18%, 20% vs 23%, 32%, 55%, respectively; χ2 = 19.431,7.515 and 17.853 respectively; and P < 0.01 for all). Conclusion The " three-in-one" asthma education and management model can significantly improve asthma control.
