RESUMO
To evaluate the effectiveness of community-based comprehensive intervention and internet-based intervention on influenza and pneumococcal vaccination in patients with diabetes or chronic obstructive pulmonary disease (COPD) in communities. Before the onset of influenza in 2015 and 2016, five demonstration areas for comprehensive prevention and control of chronic diseases were selected in the study. Patients aged 35 years old and above with diabetes and COPD were selected from selected demonstration areas as study participants. Two communities were selected from each demonstration area and randomly divided into Group A with the community-based comprehensive intervention and Group B with the combination of community-based comprehensive intervention and internet-based intervention within 6 months. The differences of vaccination knowledge, vaccination intention and vaccination proportion in study participants between the two groups before and after interventions were analyzed and compared. A total of 15 226 patients were included in the study. After the intervention the increase in the vaccine knowledge score, vaccination intention and vaccination proportion of patients in the two groups were all higher than those before the intervention. After intervention, the increase of the median score of vaccine knowledge in group B (50.00 points) was higher than that in Group A (42.86 points). The increase of influenza vaccination intention in Group B (6.91%) was higher than that in Group A (4.16%). The increase of proportion of influenza vaccination in Group B (7.35%) was lower than that in Group A (16.61%). The increase of pneumococcal vaccination intention in Group B (7.90%) was lower than that in Group A (9.08%). The proportion of pneumococcal vaccination in Group B (3.37%) was lower than that in Group A (4.06%). Community-based comprehensive intervention could improve the level of vaccine knowledge, vaccination intention and vaccination proportion of patients in this study. Combined with community-based intervention, internet-based intervention could have a better effect on improving vaccine knowledge and influenza vaccination intention, but its impact on vaccination proportion needs to be further explored.

Objective: To assess the impact of Chinese Cervical Cancer Screening Program for Rural Area (NACCSPRA) on population-based screening rates. Methods: The subjects were selected from 2013-2014 Chinese Chronic Diseases and Risk Factors Surveillance (CDRFS2013), which adopting multi-stage stratified cluster sampling from 31 provinces. A total of 169 632 participants aged 18 years and older in 297 surveillance points were interviewed, of whom 65 476 women aged 35-64 years were included in the analysis. The surveillance points in CDRFS 2013 were divided into the screening areas and the control areas by matching points in CDRFS2014 with counties in NACCSPRA. The difference in socioeconomic status between areas was compared. The screening rates and 95% confidence interval (95%CI) were estimated by Tylar series variance method. The Propensity Score was evaluated for individuals by multivariate logistic regression and the greedy matching method based on propensity score value was used to conduct 1â¶1 matching sample for the screening areas and the control areas. After matching, multivariate conditional logistic regression model was fitted to assess the impact of national cervical cancer screening intervention on the likelihood of undergoing cervical cancer screening at population level. Results: Among 65 476 subjects, 48.6% (n=31 794) was in the screening areas. Before matching, in the rural area the screening rate in the screening areas (24.0% (4 763/19 838), 95%CI: 21.8%-26.3%) was higher than that in the control areas (15.6% (2 331/14 942), 95%CI: 13.4%-17.8%); whereas in the urban area the screening rate in the screening areas (28.5% (3 413/11 956), 95%CI: 26.1%-31.0%) was similar to that in the control areas (26.3% (4 923/18 740), 95%CI: 24.1%-28.4%). After matching, in rural area the screening rate in the screening areas (23.2% (3 454/14 875), 95% CI: 20.9%-25.5%) was higher than that in the control areas (15.6% (2 315/14 875), 95% CI: 13.3%-17.8%); in urban area the screening rate in the screening areas (28.7% (3 202/11 146), 95% CI: 26.2%-31.2%) was higher than that in the control areas (23.1% (2 571/11 146), 95%CI: 20.9%-25.3%). Multivariate conditional logistic regression model showed that the cervical cancer screening rates in intervention areas significantly increased among women aged 35-64 years both in urban areas (OR=1.44, 95%CI: 1.34-1.54) and rural areas (OR=1.78, 95%CI: 1.67-1.90) as compared with those in control areas. Conclusion: The implementation of Chinese cervical cancer screening program during the five years substantially increased the population-based screening rates both in urban and rural areas.

Cervical cancer is one of the most common malignancies among women. Screening programs for cervical cancer have been implemented in many developed countries. Comprehensive systems for cervical cancer prevention and control have improved over the past 30 years, which has led to a significant decline in the morbidity and mortality of cervical cancer. Since 2009, the Chinese government has conducted the Cervical Cancer and Breast Cancer Screening Program for Rural Women on a national scale, which has substantially improved cervical cancer prevention and control. However, a comprehensive system for cervical cancer prevention has been not established in China. It is essential to investigate suitable strategies for cervical cancer prevention system in the country by referring to the experiences of developed nations in comparison with the situation in China, with respect to system operations, compatibility with the existing health care system, choice of suitable technologies, and information and evaluation platforms.

OBJECTIVE: To describe the changing demographic profile over time of pregnant women diagnosed with HIV infection, and trends in mode of delivery and pregnancy outcome. METHODS: An observational investigation was conducted based on a population of 1 128 HIV-positive pregnant women at eight sites in China in provinces with high prevalence of HIV among pregnant women and children between 2007 and 2013. The study area included Shangcai and Weishi counties in Henan province; Ruili and Longchuan counties and Linxiang prefecture in Yunnan province; Yining County in Xinjiang; and Lingshan county and Babu district in Guangxi province. Main outcome measures were maternal characteristics, mode of delivery, and related trends over time by Cochram-Mantel-Haenszel(CMH) χ(2)-test. RESULTS: A total hospital delivery rate of 96.4% was reported. For each year during the period 2007-2013, hospital delivery rates were 95.1% (253/266), 94.8% (188/198), 93.7% (164/175), 98.8% (159/161), 98.6% (141/143), 97.4% (114/117), and 100.0% (68/68), respectively (χ(2)CMH=7.68, P=0.006). The neonatal survival rate increased by 0.7% incrementally from 2007 to 2013, with 98.5% (262/266), 99.0% (196/198), 99.4% (174/175), 99.4% (160/161), 100.0% (143/143), 100.0% (117/117), and 100.0% (68/68), respectively (χ(2)CMH=4.58, P=0.030). The proportions of vaginal deliveries in those years were 62.2% (166/266), 54.8% (109/198), 59.9% (105/175), 61.7% (100/161), 66.7% (96/143), 58.8% (69/117), and 66.7% (46/68), respectively (χ(2)CMH=1.19, P= 0.276). The average rate for midwives skilled in procedures such as artificial rupture of membranes and episiotomy was 37.8% (261/691), with proportions decreasing during the study period at 39.2% (65/166), 47.4% (52/109), 35.9% (38/105), 46.0% (46/100), 25.5% (25/96), 31.2% (22/69), and 28.3% (13/46), respectively (χ(2CMH)=6.76, P=0.009). CONCLUSION: The annual rate of reported hospital delivery increased between 2007 and 2013, with a declining rate of skilled midwifery over the same period. Survival of neonates born to HIV-infected mothers in China has increased to nearly equivalent levels as those of developed countries.

Objective: To understand the current status of occupational exposure to dust or harmful gases and occupational protection in people aged ≥40 years in China, and provide data support for the prevention and control of occupational dust or harmful gas exposure. Methods: The data were obtained from the surveillance for chronic obstructive pulmonary disease (COPD) in adults aged ≥40 years selected by multi-stage stratified cluster sampling from 125 surveillance points in 31 provinces (autonomous regions and municipalities) during 2014-2015 and 2019-2020, and relevant information about occupational dust or harmful gas exposure and protection measures were collected through face-to-face interviews. Occupational dust or harmful gas exposure rate and occupational protection rate were estimated by using weighting complex sampling methods, and then the results were compared. Results: From 2014 to 2015 and from 2019 to 2020, a total of 71 061 and 71 023 individuals aged ≥40 years were surveyed, respectively. The rate of occupational exposure to dust or hazardous gas was 33.8% (95%CI: 29.9%-37.7%) during 2019-2020. The occupational exposure rate was higher in men than in women and in rural residents than in urban residents. With the increase of education level, the rate of occupational exposure to dust or harmful gas showed a downward trend. The protection rate against occupational dust or hazardous gas exposure was 47.9% (95%CI: 43.2%-52.6%) during 2019-2020. Compared with 2014-2015, the rate of occupational exposure to dust or hazardous gas decreased by 10.7 percentage points in different gender, area and occupational groups and the occupational protection rate increased by 21.9 percentage points during 2019-2020. The decrease in occupational exposure rate was higher in western China than in eastern and central China, and the increase in occupational protection rate was higher in western China than in eastern and central China. Conclusions: The rate of occupational exposure to dust or harmful gas decreased and the rate of occupational protection against dust or harmful gas exposure increased in China during 2019-2020. However, about one-third of the population still suffer from the occupational exposure, and less than half of them take protection measures. It is necessary to pay more attention to the key populations, such as workers with lower cultural level and rural migrant workers, in occupational health practice.

Objective: To understand the passive smoking exposure status in adults aged ≥40 years in China. Methods: Local residents aged ≥40 years were enrolled as study subjects from 125 areas of chronic obstructive pulmonary disease (COPD) surveillance during 2014-2015 and 2019-2020 in 31 provinces of China. A total of 74 559 adults aged ≥40 years were selected through multi-stage stratified cluster sampling for a face to face questionnaire survey and the data from 64 142 study subjects were used for the analysis. The passive smoking exposure rate, the proportions of the adults reporting passive smoking exposure at four types of places and the proportion of the adults living with daily smokers were described by using complicated sampling weighting method, the related factors were analyzed and the results were compared with the data of COPD surveillance during 2014-2015. Results: The passive smoking exposure rate in the adults aged ≥40 years was 46.4% (95%CI: 44.1%-48.8%) in China during 2019-2020, and the rate was higher in women (47.2%, 95%CI:44.8%-49.7%) than in men (44.8%, 95%CI:42.0%-47.6%) and lower in the older people. The office workers had the highest passive smoking exposure rate. The proportions of those reporting passive smoking exposure at homes, workplaces, restaurants, and public transports were 24.3% (95%CI:22.2%-26.4%)ã23.3% (95%CI:21.1%-25.5%)ã6.6% (95%CI:5.3%-7.9%) and 2.2% (95%CI:1.6%-2.7%). The higher education level the adults had, the less passive smoking exposure at home they reported. The proportions of those living with daily smokers before 14 years old and since 14 years old were 56.4% and 59.2%. Compared with the data during 2014-2015, the overall passive smoking exposure rate in the adults aged ≥40 years during 2019-2020 showed an increase, and the difference was not significant (P=0.356); The passive smoking exposure rate at homes declined, but the exposure rate at workplaces increased, with the biggest increase found in those being engaged in farming, forestry, husbandry, fishery and water conservancy. Multivariate analysis indicated that the factors influencing the passive smoking exposure and the exposure proportions at different places included gender, age, occupation, and education level. Conclusions: The passive smoking exposure rate in China is still high, especially in those being engaged in farming, forestry, husbandry, fishery and water conservancy. It is necessary to strengthen supervision of the enforcement of current smoking bans in public places and promote the legislation of ban smoking in public places. More attention should be paid to smoking ban and protection against passive smoking exposure in women, people with lower education level and people being engaged in in farming, forestry, husbandry, fishery and water conservancy.

Objective: To understand the performance of pulmonary function tests in people aged ≥40 years and its changes in China, and provide evidence for the evaluation of the effect of chronic obstructive pulmonary disease (COPD) prevention and control in China. Methods: The subjects of the survey were from COPD surveillance during 2014-2015 and during 2019-2020, which covered 31 provinces (autonomous regions and municipalities) in China. The survey used multi-stage stratified cluster random sampling method, the trained investigators conducted face-to-face interview to know whether subjects had previous pulmonary function testing or not. Complex sampling weighting was used to estimate the rate of pulmonary function testing in people aged ≥40 years, and the pulmonary function testing rates of the two COPD surveillance periods were compared. Results: A total of 148 427 persons were included in the analysis, including 74 591 persons during 2014-2015 and 73 836 persons during 2019-2020. In 2019-2020, the pulmonary function testing rate in Chinese residents aged ≥40 years was 6.7% (95%CI: 5.2%-8.2%), the rate in men (8.1%, 95%CI: 6.7%-9.6%) was higher than that in women (5.4%, 95%CI: 3.7%- 7.0%), and the rate in urban residents (8.3%, 95%CI: 6.1%-10.5%) was higher than that in rural residents (4.4%, 95%CI: 3.8%-5.1%). The rate of pulmonary function testing increased with the increase of education level. During 2019-2020, the residents with history of chronic respiratory diseases had the highest rate of pulmonary function testing (21.2%, 95%CI: 16.8%-25.7%), followed by the residents with respiratory symptoms (15.1%, 95%CI: 11.8%-18.4%) , the pulmonary function testing rate in those who knew the name of chronic respiratory disease was higher than that in those who did not knew the name of respiratory disease, and the pulmonary function testing rate in former smokers was higher than that in current smokers and non-smokers. Those exposed to occupational dust and/or harmful gases had a higher rate of pulmonary function testing compared with those who were not exposed, and those who used polluted fuels indoors had a lower rate of pulmonary function testing than those who did not use polluted fuels indoors (all P<0.05). Compared with 2014-2015, the pulmonary function testing rate in residents aged ≥40 years in China increased by 1.9 percentage points during 2019-2020, and the rate of pulmonary function testing in groups with different characteristics all increased, and the rates of pulmonary function testing increased by 7.4 percentage points and 7.1 percentage points in residents with respiratory symptoms and in those with history of chronic respiratory diseases (all P<0.05). Conclusions: Compared with 2014-2015, the rate of pulmonary function testing increased in China during 2019-2020 and the increase in residents with history of chronic respiratory diseases and respiratory symptoms was relatively obvious, but the overall pulmonary function testing rate was still at a low level. Effective measures should be taken to further increase the rate of pulmonary function testing.

Objective: To understand the prevalence of exposure to household cooking oil fumes in women ≥40 years old. Methods: The data were from Chronic Obstructive Pulmonary Disease (COPD) Surveillance in China during 2019-2020, which selected permanent residents ≥40 years old from 125 counties (districts) in 31 provinces (autonomous regions and municipalities) across the country by multi-stage stratified cluster random sampling method. The relevant demographic information and cooking oil fumes were collected by face-to-face interview. Our study served 37 164 women with complete cooking practice information as the subject. After complex sample weighting, we analyzed the prevalence of cooking oil fumes exposure in women from cooking time, kitchen characteristics, and Self-reported cooking oil fumes exposure. Results: In 2019, 83.9% (95%CI: 82.1%-85.7%) and 4.5% (95%CI: 3.8%-5.2%) of Chinese women ≥40 years old cooked daily and often, respectively. The average daily cooking duration is 1.8 hours/day, 31.1% of women who cooked daily more than 2.0 hours, and the average cumulative cooking years of cooking women were 32.8 years. 79.3% of cooking women used ventilation devices, and 3.2% cooked in the living room. 8.9% and 7.2% of cooking women in south China and northwest China cooked in the living room, significantly higher than in other regions (P=0.036). The self-reported exposure rate to cooking oil fumes was 81.0% (95%CI: 79.3%-82.7%). Rural, older, lower education level and women engaged in agriculture had a higher proportion of cooking daily, average daily cooking duration, cumulative cooking years, the proportion of cooking in the living room, and rate of self-reported cooking oil fumes exposure, but a lower proportion of using ventilation devices during cooking (P<0.001). Conclusions: The exposure to household cooking oil fumes was serious in Chinese women, and some women still did not take any ventilation measures when cooking. More attention should be paid to the exposure to home cooking oil fumes and its health hazards in women, especially those with lower socioeconomic status.

Objective: To understand the prevalence of smoking and its change in adults aged ≥40 years in China and provide evidence for the development of chronic obstructive pulmonary disease (COPD) prevention and control strategies. Methods: The data of this study were obtained from COPD surveillance in China during 2014-2015 and during 2019-2020. The surveillance covered 31 provinces (autonomous regions and municipalities). A multi-stage stratified cluster random sampling were used to select residents aged ≥40 years, and face-to-face interviews were conducted to collect the information about their tobacco use. After complex sampling weighting of the samples, the current smoking rate, average age to start smoking and average daily cigarette consumption of people with different characteristics during 2019-2020 were estimated, and the changes in the current smoking rate and average daily cigarette consumption were analyzed from 2014-2015 to 2019-2020. Results: During 2019-2020, the current smoking rate in adults aged ≥40 years was 27.2%, and the rate was much higher in men (52.1%) than in women (2.5%).The average age of the smokers to start smoking was 20.0 years old, and men usually started smoking at younger age (19.6 years) compared with women (27.9 years). The average daily cigarette consumption of daily smokers was 18.0 sticks, and the consumption of men (18.3 cigarettes) was higher than that of women (11.1 cigarettes). Compared with the surveillance results during 2014-2015, the current smoking rate had decreased by 2.8 percentage points in the general population, 4.1 percentage points in males, 1.6 percentage points in females, and the urban and rural areas fell by 3.1 percentage points and 2.5 percentage points, respectively. The average daily cigarette consumption decreased by 0.6 sticks. Conclusions: In recent years, the current smoking rate and average daily cigarette consumption in adults aged ≥40 years decreased in China, but smoking is still common in more than quarter of this population and more than half of men aged ≥40 years. It is necessary to take targeted tobacco control measures based on population and regional characteristics to further reduce the smoking level of the population.

Objective: To investigate the clinical features of coronavirus disease 2019 (COVID-19) in patients with aplastic anemia (AA) undergoing immunosuppressive therapy (IST) . Methods: In this prospective cohort study, we collected the demographic and clinical data of patients with AA and COVID-19 from December 1, 2022, to January 31, 2023. We described the clinical features of COVID-19 among patients with AA and evaluated the effects of IST on the signs and severity of COVID-19. Results: A total of 170 patients with AA and COVID-19 were included. The common early symptoms, including fever, dizziness or headache, muscle or body aches, and sore throat, disappeared within 1-2 weeks. Approximately 25% of the patients had persistent fatigue within 2 weeks. Many patients experienced cough after an initial 1-3 days of infection, which lasted for more than 2 weeks. There were no differences in the duration of total fever episodes and maximum body temperature when patients were stratified according to whether or not they underwent IST, by IST duration, or by use of anti-lymphocyte globulin (ALG) (P>0.05). No differences were observed in the occurrence of symptoms in either the early or recovery stages when patients with AA were stratified according to whether or not they underwent IST, or by IST duration (P>0.05). However, patients who received ALG had fewer fever episodes within 1 week after infection (P=0.035) and more sore throat episodes within 2 weeks after infection (P=0.015). There were no other significant differences in clinical symptoms between patients who did and patients who did not receive ALG (P>0.05) . Conclusion: The majority of patients with AA and COVID-19 recovered within 2 weeks of noticing symptoms when treated with IST.

Objective: To understand the prevalence of chronic cough, chronic expectoration and dyspnea and related factors in residents aged ≥40 years in China, and provide basic data for the prevention and control of chronic respiratory diseases. Methods: Data were from 2014-2015 chronic obstructive pulmonary disease surveillance in China. The information about chronic respiratory symptoms were collected by face-to-face interview. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms and their 95%CI were estimated with complex sampling weights. Results: A total of 75 082 subjects were included in the analysis. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in the Chinese aged ≥40 years were 3.75% (95%CI: 3.38%-4.11%), 5.83% (95%CI: 5.40%-6.26%), 2.45% (95%CI: 2.02%-2.87%) and 8.93% (95%CI: 8.25%-9.62%), respectively. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in patients with chronic respiratory diseases were relatively higher, which were 10.27%, 13.85%, 6.43%, 20.72% respectively. Multivariate logistic regression analysis showed that age, region, education level, occupation, BMI, family history of respiratory diseases, history of severe respiratory infections in childhood, exposure to dust or chemicals in workplace and smoking status affected the prevalence of chronic cough, chronic expectoration and dyspnea. The prevalence of the three types of chronic respiratory symptoms increased significantly with age, which were higher in western region, smokers and underweight/obese subjects. The three prevalence rates mentioned above were higher in those with a history of severe respiratory infection in childhood, those exposed to biomass fuel in household, and those exposed to dust or chemicals in workplace. Conclusions: The prevalence rate of chronic respiratory symptoms was high in residents aged ≥40 years in China. Many factors affected the prevalence of chronic respiratory symptoms. Comprehensive prevention and control measures targeting risk factors should be taken to reduce the burden of chronic respiratory diseases.

Objective: To understanding tobacco dependence and its influencing factors among smokers aged 40 or older in China and provide scientific data for the implementation of smoking cessation intervention. Methods: The data of this study were collected from 125 surveillance sites in 31 provinces (autonomous regions and municipalities) of chronic obstructive pulmonary disease (COPD) surveillance in China (2014 and 2015). The relevant variables of smoking status and tobacco dependence among people aged 40 or older were collected by face-to-face interview. The weighted proportion of tobacco dependence and its 95%CI and influencing factors among current smokers and daily smokers aged 40 or older in China were estimated with complex sampling weights. Results: A total of 22 380 current smokers and 19 999 daily smokers were included in the analysis. The proportion of high tobacco dependence of current smokers aged 40 or older was 31.1% (29.3%-32.9%). The proportion of high tobacco dependence was higher in men than in women, and higher in rural smokers than urban smokers. The proportion was 33.3% (31.3%-35.2%) in 40 to 59 years old smokers, which was higher than older age group. The proportion of high tobacco dependence among daily smokers aged 40 or older was 35.0% (33.0%-37.0%), and was 35.8% (33.8%-37.8%) in men and 22.0% (16.8%-27.2%) in women. Among current smokers and daily smokers, with the decrease of education level, the proportion of high tobacco dependence increased. The proportion of high tobacco dependence of smokers who started smoking before 18 years old was significantly higher than those who started smoking after 18 years old. The ratio of high tobacco dependence of smokers with chronic respiratory symptoms was higher than that of asymptomatic smokers. There was no significant difference in the tobacco dependence between patients with chronic diseases or chronic respiratory diseases and non patients (P>0.05). Smokers with diabetes, cardiovascular and cerebrovascular diseases and hypertension had a slightly lower proportion of high tobacco dependence than smokers without above diseases (P<0.05). Multivariate logistic regression analysis showed that men, central and eastern regions, 40-59 age group, engaged in agriculture, forestry, animal husbandry, fishery industry, water conservancy, manufacture, transportation and commercial services occupation, low education level and smoking onset age less than 18 years old had a high risk of high tobacco dependence. Conclusions: The proportion of high tobacco dependence among current smokers aged 40 or older is high in China, so there is a huge demand for smoking cessation interventions. Effective measures should be taken to promote smoking cessation intervention in China.

Objective: To explore the diagnostic process and outcomes of patients with aplastic anemia (AA) who received outpatient treatment in a real-world setting. Methods: The diagnostic processes, treatment regimens, and outcomes of 176 patients with AA treated in outpatient centers from January 2018 to December 2019 were reviewed. Results: The median interval from the onset of symptoms to the first visit was 7 (5-120) months. Complaints during the first visit included bleeding (52.3% ) , anemia (51.7% ) , and infection (6.8% ) . For diagnosis, 168 patients (95.5% ) underwent bone marrow aspiration; however, only 22 of them (17.1% ) consented aspiration in multiple sites (sternum) . The completion rate of bone marrow biopsy was 85.1% (143/168) ; flow immunophenotype and karyotype analyses were performed on 59.5% (100/168) and 58.9% (99/168) of AA patients, respectively, and the culture of clonal forming units by bone marrow mononuclear cells was performed on 26.8% (45/168) of AA patients. The most preferred regimen was cyclosporine combined with androgen and levamisole (43.8% , 77 patients) , followed by cyclosporine combined with androgen (25.6% , 45 patients) . Cyclosporine alone was administered in 24 patients (13.6% ) and androgen alone in 16 patients (9.1% ) . Furthermore, 14 patients (7.9% ) did not consent to any drugs or only chose traditional Chinese medicine. The patients were divided according to the frequencies of follow-up: regular follow-up group (≥4 times/year, n=130) and irregular group (<4 times/year, n=46) . The former had a higher 6-month remission rate (52.5% vs 28.0% , P=0.005) , a greater high-quality remission rate in 12 months (40.7% vs 16.7% , P=0.027) , and a lower relapse rate in 24 months (4.4% vs 36.4% , P=0.001) . Conclusion: In real-world settings, bone marrow aspiration in multiple sites should be addressed in outpatient treatment for AA diagnostic work-up, including PNH clone screening, flow immunophenotype, chromosome karyotype analysis, and culture of clonal forming units. Patients with AA who follow regular visits were more likely to achieve high-quality remission and a lower relapse rate. Visits at least four times per year are recommended for AA patients undergoing outpatient treatment.

Objective: To explore the efficacy and safety of ibrutinib treatment for relapsed/refractory (R/R) primary autoimmune hemolytic anemia (AIHA) . Methods: Two cases of primary AIHA with relapse events were refractory to glucocorticoid, anti-CD20 monoclonal antibody, immunosuppressive drugs, and splenectomy (case 1 only) . Ibrutinib treatment was administered at an initial dose of 280 mg/d (420 mg/d for case 1 from the 3rd to 8th week) . Results: Both patients achieved transfusion independence and HGB>20 g/L above baseline after 2 weeks (partial response) . For case 1, HGB concentration restored to 113 g/L but with incomplete hemolysis recovery after 10 weeks; HGB reached the level of 118 g/L, also with incomplete hemolysis recovery, after 6 weeks in case 2. They all acquired complete response with incomplete hemolysis recovery (CRi) . The responses sustained 14 weeks and 10 weeks after follow-up at 16 weeks and 12 weeks, respectively. During the treatment, hematologic and nonhematologic toxicity is mild and acceptable. Conclusion: Ibrutinib alone is effective for the 2 R/R primary AIHA cases. We need further clinical trial to identify its efficacy and safety.

Objective: To understand the situation of respiratory rehabilitation and oxygen inhalation therapy in chronic obstructive pulmonary disease (COPD) patients aged 40 years or older in China, and provide basic information for the development of pulmonary rehabilitation. Methods: The data were from 2014-2015 COPD surveillance in China. Chinese residents aged 40 years or older were recruited through a complex multi-stage stratified cluster sampling from 125 COPD surveillance points in 31 provinces (autonomous regions, municipalities). Standardized face to face electronic questionnaires were used to collect information about respiratory rehabilitation and oxygen inhalation therapy of the patients. Spirometry was performed on all participants, and patients with post- bronchodilator FEV(1)/FVC<70% were diagnosed with COPD. The number of defined COPD patients was 9 134. Based on the complex sampling design, the respiratory rehabilitation treatment rate and oxygen inhalation therapy rate of COPD patients aged 40 years old or older in China were estimated, and the influencing factors were analyzed. Results: A total of 9 118 COPD patients aged 40 years or older were included in the analysis. The rate of respiratory rehabilitation was 0.8% (95CI: 0.6%-1.0%), and the rate of oxygen inhalation therapy was 2.5% (95%CI: 2.0%-2.9%). Among patients with severe symptoms or high risk of acute exacerbation (combined COPD assessment groups B, C, D), the rate of respiratory rehabilitation was 1.4% (95%CI: 0.9%-1.9%), and the rate of oxygen inhalation therapy was 5.4% (95%CI: 4.4%-6.4%). Multivariate logistic regression analysis showed that urban or rural residences, geographic area, awareness of COPD, history of acute exacerbation and severity of airflow restriction had influences on the respiratory rehabilitation rate in the COPD patients. Gender, geographic area, awareness of COPD, history of acute exacerbation, mMRC scores and severity of airflow restriction had influences on the patients' oxygen inhalation therapy rate. Conclusions: The rate of respiratory rehabilitation and oxygen inhalation therapy in COPD patients aged 40 years or older was relatively low in China. It is necessary to explore an effective model of pulmonary rehabilitation and COPD management, so that more COPD patients may have access to scientific pulmonary rehabilitation treatment.

Objective: To understand the smoking cessation behaviors in chronic obstructive pulmonary disease (COPD) patients aged 40 years or older in China and provide evidence for COPD control and prevention. Methods: COPD patients with post-bronchodilator FEV(1)/FVC<70% were selected from COPD surveillance (2014-2015) of China, in which 5 791 current or former smokers defined by questionnaire survey were included in the study. The smoking cessation rate/ratio and the successful smoking cessation rate in COPD patients, the successful smoking cessation rate in COPD patients who ever smoked daily and the rate of attempting to quit smoking in current smokers with COPD were estimated using data adjusted by complicated sampling method. Results: The smoking cessation rate was 25.0% and the successful smoking cessation rate was 19.1% in COPD patients aged 40 years or older who ever smoked. The smoking cessation ratio was 23.1% and the successful smoking cessation ratio was 17.6% in COPD patients who ever smoked daily. The rate and ratio were higher in urban area than rural area (P<0.05) and increased with age (P<0.05). Patients who were aware of smoking being a risk factor for COPD had higher rate and ratio than patients who were not aware (P<0.05). Patients with more severe airflow limitation and patients smoking less had higher rate and ratio (P<0.05). Conclusions: The smoking cessation rate and ratio were low in COPD patients in China. More health education for COPD patients about smoking cessation needs to be strengthened. It is suggested for healthcare workers to actively advise smoking cessation and suggest smoking cessation ways for patients who smoke in their routine clinical service to increase the successful smoking cessation rate/ratio in COPD patients.

Objective: To understand the pneumococcal vaccination rate in chronic obstructive pulmonary disease (COPD) patients aged 40 years or older in China and provide evidence for COPD control and prevention. Methods: COPD patients with post-bronchodilator FEV(1)/FVC<70% in COPD surveillance (2014-2015) of China were used as study subjects, in which 9 067 patients with definite pneumococcal vaccination status were included. The pneumococcal vaccination rate and its 95%CI in COPD patients were estimated using data adjusted by complicated sampling method. The factors in association with the vaccination rate were also identified. Results: The pneumococcal vaccination rate was 0.8% in the past five years in COPD patients aged 40 years or older in China (95%CI: 0.3%-1.4%). The vaccination rate was 0.3% in the patients aged 40 to 59 years (95%CI: 0.2%-0.5%) and 1.2% in the patients aged 60 years or older (95%CI: 0.3%-2.1%) (P<0.05). The rate was higher in the patients living in urban area (1.5%) than in those living in rural area (0.4%) (P<0.05). The vaccination rate increased with the severity of airflow limitation (P<0.05). The patients with comorbidities of other chronic lung diseases or diabetes had higher vaccination rate (1.7% and 2.1%) compared with those without comorbidities (P<0.05). The vaccination rate was 1.4% in former smokers and 0.6% in current smokers. The pneumococcal vaccination rate in COPD patients was associated with age, education level, occupation, the severity of airflow limitation and the history of influenza vaccination. Conclusions: The pneumococcal vaccination rate was extremely low in COPD patients aged 40 years or older in China. It is necessary to strengthen the health education and recommendation for pneumococcal vaccination in COPD patients through different measures.

Objective: To understand the awareness of chronic obstructive pulmonary disease (COPD) status and awareness of COPD-related knowledge and its influencing factors in COPD patients aged ≥40 years in China in 2014-2015. Methods: The study subjects were selected through multi-stage stratified cluster sampling from 125 COPD surveillance points in 31 provinces (autonomous regions, municipalities) in China. The number of the subjects was 75 107. The relevant variables about COPD diagnosis and COPD-related knowledge awareness were collected by electronic questionnaire in face to face interviews. A total of 9 134 participates with post-bronchodilator FEV(1)/FVC<70% were diagnosed with COPD. Based on the complex sampling design, the awareness rate of COPD status and related knowledge were estimated, and the influencing factors were analyzed. Results: A total of 9 132 COPD patients were included in the analysis. Among COPD patients aged ≥40 years in China, 0.9% were aware of their COPD status (95%CI: 0.6%-1.1%), and 5.7% were aware of COPD related knowledge (95%CI: 4.8%-6.6%), and 3.4% were aware of pulmonary function test (95%CI: 2.8%-4.0%). The COPD status awareness rate was 3.9% in the patients with history of chronic respiratory disease (95%CI: 2.9%-4.8%), 2.4% in the patients with respiratory symptoms (95%CI: 1.7%-3.1%), and 7.1% in the patients with COPD related knowledge awareness (95%CI: 4.5%-9.8%) respectively. The results of multivariate logistic regression analysis showed that chronic respiratory disease history, respiratory symptoms, occupational dust and/or harmful gas exposure and COPD related knowledge awareness had influences on the awareness rate of COPD status. Educational level and chronic respiratory disease history had influences on the awareness rate of COPD related knowledge. And ethnic groups, educational level and history of chronic respiratory diseases had influences on the awareness rate of pulmonary function test. Conclusions: The awareness rates of COPD status, COPD-related knowledge and pulmonary function test in COPD patients in China were low. The comprehensive intervention of COPD should be carried out to improve the level of diagnosis and the awareness COPD status of COPD patients.

Objective: To understand the rate of spirometry examination and its related factors among chronic obstructive pulmonary disease (COPD) patients aged ≥40 years in China from 2014 to 2015, and provide evidence for diagnosis, treatment and management of COPD patients normatively. Methods: Data were obtained from 2014-2015 COPD surveillance, China. The previous lung function examination status and other information of the subjects were collected by face-to-face survey. We defined COPD as a post-bronchodilator FEV(1): FVC less than 70%. A total of 9 130 COPD patients were included in the analysis of this study. The rate of spirometry examination and its 95% confidence interval (CI) were estimated in COPD patients aged ≥40 years with complicated sampling weights. Meanwhile, the spirometry examination related factors were analyzed. Results: The estimated rate of spirometry examination among COPD patients was 5.9% (95%CI: 4.9%-6.9%), 6.1% (95%CI: 5.2%-7.1%) for men and 5.3% (95%CI: 4.0%-6.6%) for women. The rate was significantly higher in urban population than in rural (P<0.001). With the increase of education level, the rate of spirometry examination among COPD patients increased gradually (P<0.001). The rate of spirometry examination was 4.0% (95%CI: 3.1%-4.9%) among COPD patients in agricultural industry. The rate of spirometry examination among COPD patients with awareness of pulmonary function test was 32.3% (95%CI: 26.4%-38.1%). The rate of spirometry examination among COPD patients with previous chronic respiratory disease and respiratory symptoms were 13.7%(95%CI:11.5%-15.9%), 8.8%(95%CI:7.2%-10.4%), respectively. The rate of spirometry examination among COPD patients exposed to occupational dust and/or harmful gases was 5.7% (95%CI: 4.6%-6.9%). The rate of spirometry examination in former smokers among COPD patients was 10.2% (95%CI: 8.0%-12.4%), higher than those in current smokers (4.2%, 95%CI: 3.3%-5.1%) and non-smokers (6.3%, 95%CI: 5.1%-7.6%). Conclusion: The rate of spirometry examination is extremely low among COPD patients aged ≥40 in China, and the standardized diagnosis, treatment and management of COPD patients need to be improved urgently.
