RESUMO
Objective: To evaluate the influencing factors of poor treatment adherence in patients with uncontrolled asthma in China. Methods: From April 2017 to April 2018, all asthma patients with uncontrolled asthma and poor compliance in 32 third-class hospitals in 28 provinces and cities of China mainland included in the "National Mobile Asthma Assessment and Management Project" were selected as the subjects. A total of 923 patients were enrolled in the study including 388 males and 535 females. By analyzing the baseline data of the patients at the initial visit when enrolled, the influencing factors of poor adherence of adult asthma was analyzed by inter-group comparison and χ2 test. Results: Poor compliance in asthma was related to the following factors: age from 59 to 68 years old, course of disease more than 20 years, low education level, non-local follow-up, having obstructive ventilation dysfunction and low awareness of the disease[P values were 0.026(t=1.20), 0.004(t=3.97), 0.001(t=4.92), 0.003(t=3.98), 0.032(t=1.22) and 0.001(t=4.99), respectively]. Totally, 243 patients (26.33%) answered all the questions about asthma correctly. Their medication adherence rating scale (MARS-A) scores were significantly higher than those who answered incompletely correctly (36.23±5.85 vs. 31.77±5.74, P=0.001). Conclusions: The adherence of adult asthma patients was affected by individual and external environment factors. Clinicians should choose individualized methods based on the characteristics of patients. Patient education should be strengthened to improve patients' awareness of the disease at the same time.

Objective: To investigate the correlation and sex difference between obstructive sleep apnea hypopnea syndrome (OSAHS) and liver injury. Methods: A total of 974 OSAHS patients (444 cases of mild to moderate, 530 cases of severe) and 111 cases of simple snoring in the First Affiliated Hospital of Fujian Medical University and Zhangzhou Municipal Hospital from November 2015 to September 2019 were included in the study. The basic information of the patients was obtained through face-to-face survey with self-made questionnaire, physical examination, sleep monitoring and blood biochemical and liver function index detection were carried out among the included subjects. Multiple logistic regression model was used to analyze the correlation between OSAHS and liver injury and the gender differences. Results: The subjects were (50±14) years old, including 841 males (77.5%). Statistically significant differences in total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), fasting blood glucose, alamine aminotransferase (ALT), aspartate aminotransferase (AST), ALT/AST, gamma glutamyltransferase (GGT), the rate of elevated ALT, AST and liver injury were observed among the three groups (all P values<0.05). There was no significant difference in total bilirubin and ALP among all groups (all P values>0.05). Multivariate logistic regression showed that after adjusting for confounding factors, severe OSAHS was positively correlated with liver injury [OR (95%CI): 2.25 (1.22-4.14)]. Subgroup analysis by gender showed that severe OSAHS was positively correlated with liver injury in males [OR (95%CI): 2.20 (1.04-4.65)], but not in females, mild to moderate OSAHS [OR (95%CI): 1.56 (0.52-4.71)] or severe OSAHS [OR (95%CI): 2.07(0.64-6.75)], after adjusting for confounding factors. Conclusion: Severe OSAHS is positively correlated with liver injury in males, while female OSAHS is not associated with liver injury.

Objective: To analyze the related factors that affect the one-year mortality in elderly patients following hip fracture surgery. Methods: The clinical data of the elderly patients who needed a surgery for hip fracture in the Second Affiliated Hospital of Wenzhou Medical University from January 2017 to April 2018 were retrospectively analyzed. According to the inclusion criteria of the study, 489 cases were included. Then the information of patients including age, sex, Charlson comorbidity index, type of fracture, Braden score at admission, American Society of Anesthesiologists (ASA) score, length of hospital stay, type of anesthesia, whole blood cells analysis were collected. Univariate and multivariate Cox regression analyses were conducted to investigate the factors related to one-year mortality of patients. Results: After excluding 39 patients, 450 patients were finally included. Patients in this cohort study had a mortality rate of 3.33% (15/450) at 1 month, 7.78% (35/450) at half a year, and 10.89% (49/450) at 1 year after surgery. Univariate analysis showed that age, sex, ASA score, type of fracture, Charlson comorbidity index, Braden score at admission, type of analgesia, preoperative hemoglobin concentration, preoperative albumin concentration, postoperative delirium of high activity correlated with one-year mortality after surgery. Further, multivariate Cox regression analysis revealed that age>80 years old (HR=2.32, 95%CI: 1.11-4.85, P=0.025), Charlson comorbidity index ≥ 3 (HR=3.24, 95%CI:1.75-6.03, P<0.001), Braden score at admission ≤16 (HR=1.93, 95%CI:1.03-3.57, P=0.040) and postoperative delirium of high activity (HR=2.49, 95%CI:1.16-5.35, P=0.019) were risk factors for one-year mortality. Conclusions: The current study indicates that one-year mortality rate of elderly patients following hip fracture surgery is 10.89%. Meanwhile, age>80 years, Charlson comorbidity index ≥ 3, Braden score at admission ≤ 16, postoperative delirium of high activity are risk factors for one-year mortality.

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.

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 ß(2)-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.

Objective: To investigate the regulation and possible mechanism of microRNA (miR)-1249 on myocardial apoptosis in chronic intermittent hypoxia rats. Methods: A total of 16male SD rats aged 8 weeks were randomly divided into 2 groups by the random number table: normoxia control group and chronic intermittent hypoxia group (CIH) (n=8 each). The CIH group was exposed to intermittent hypoxia every day from 9: 00 to 17: 00 for 8 consecutive weeks, while the control group received the same frequency of pulse air. Hemodynamic values were measured via a cannula inserted into right common carotid artery. The expressions of miR-1249 and microtubule-associated protein light chain 3 (LC3) mRNA were observed by real-time PCR. The expressions of LC3 and Cleaved Caspase-3 were detected by Western bolt. TUNEL staining was performed to detect myocardial apoptosis. The rat cardiomyocyte cell H9C2 was divided into normoxia group, intermittent hypoxia (IH) group and miR-1249 inhibitor transfected and IH treatment group (inhibitor group). At the end of the experiment, the activation of LC3 protein in each group of cells was determined. Results: Compared with normoxia control group, left ventricle end diastolic pressure (LVEDP) increased [(4.6±0.4) vs (2.2±0.1) mmHg (1 mmHg=0.133 kPa)], left ventricular systolic pressure (LVSP) , maximal rate of pressure decline (-dp/dtmax), and maximal rate of pressure development (+ dp/dtmax) decreased in CIH group [(92.7±4.1) vs (135.3±3.2) mmHg, (4 247±108) vs (7 626±235) mmHg/s, and (3 168±105) vs (6 028±81) mmHg/s] (all P<0.001). The expression of miR-1249 and LC3 mRNA were significantly higher in CIH group than that in normoxia control group (all P<0.001), and a positive correlation was found between the expression of LC3 mRNA and miR-1249. The expression of LC3 and Cleaved Caspase-3 protein in myocardial tissue of CIH rats were significantly higher than that of the normoxia control group (all P<0.001). The proportion of myocardial cell apoptosis in CIH rats was significantly higher than that in the normoxia control group [(23.84±4.94)% vs (2.93±0.73)%] (P<0.001). The activation of LC3 in myocardial cells of inhibitor group was significantly lower than that of IH group, but higher than that in normoxia group. Conclusions: CIH could induce LC3 by raising the expression of miR-1249, and then induce the activation of apoptosis protein Caspase3. It ultimately induces myocardial apoptosis.

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.

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.

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.

Objective: To evaluate the changes of asthma control, disease management and perception in recent years in China. Methods: We conducted 2 multi-center, cross-sectional surveys. Outpatient asthmatic patients from 10 cities in mainland China (2007-2008) and 30 central cities from 30 provinces in China (except Tibet)(2015-2016) were recruited respectively. Data of asthma control, disease management and perception from the 2 surveys were compared for 10 cities which took part in both of the 2 surveys. Chi-square test was used for comparison between groups. Results: The asthma control level improved from 28.7%(839/2 928) in 2007-2008 to 39.2%(533/1 361) in 2015-2016(P<0.01). The rate of emergency visits was 18.2%(248/1 362) in 2015-2016, which was lower than that in 2007-2008(33.9%, 1 032/3 044)(P<0.01). The rate of peak flow meter (PFM) usage was 17.9%(244/1 360) in 2015-2016, which was slightly lower than the PFM usage rate in 2007-2008(21.8%, 660/3 030)(P=0.004). 56.0%(763/1 362) of the patients used inhaled corticosteroid (ICS) + formoterol to control asthma when asthma symptoms deteriorated in 2015-2016, which was higher than the result of 2007-2008(31.8%, 803/2 524)(P<0.01). 71.1%(968/1 361) of the patients in 2015-2016 had a right perception on disease nature, while the result in 2007-2008 was 63.3%(1 889/2 986)(P<0.01). 61.6%(839/1 362) of the patients in 2015-2016 had a right perception on medication choice on daily-use first-line medication for chronic asthma, while the result in 2007-2008 was 51.0%(1 500/2 942)(P<0.01). Conclusion: The current level of asthma control and disease perception in China improved significantly in recent years, while the rate of PFM usage showed no significant improvement. Asthma action plan including PFM monitoring and asthma self-management should be further promoted nationwide.

Objective: To investigate the effects of Yiqi Huatan Quyu prescription on oxidative stress and pathological changes in chronic intermittent hypoxia rats liver. Methods: A total of 24 male SD rats aged eight weeks were randomly divided into 3 groups by the random number table: normal control group (NC), chronic intermittent hypoxia group (CIH) and chronic intermittent hypoxia plus Yiqi Huatan Quyu prescription supplement group (Chinese medicine group, CM)(n=8 each). The CIH group and CIHN group were exposed to intermittent hypoxia every day for 8 consecutive weeks. In addition, the CIHN group received Yiqi Huatan Quyu prescription via gavage 30 min before the CIH. Eight weeks later, serums were collected to test alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level. Meanwhile, rat livers were extracted to evaluate malondialdehyde (MDA), total superoxide dismutase (T-SOD), glutathione (GSH) and Nuclear factor κB (NF-κB) and observe the pathological changes of liver. Results: The levels of serum ALT and AST in the CIH group were significantly higher than those of NC group[(112.1±31.7) vs (41.3±6.6) U/L, (295.4±39.8) vs (104.5±12.3) U/L], the contents of the MDA and NF-κB in the CIH group were notably higher than those of NC group[(7.9±1.1) vs (3.6±0.7) nmol/mgprot, (16.2±3.3) vs (5.7±2.2) ng/L], the activities of T-SOD and GSH in the CIH group were significantly lower than those of control group[(181.6±28.6) vs (304.3±42.9) U/mgprot, (5.5±1.3) vs (14.9±2.4) mg/gprot](all P<0.001). The levels of the serum ALT and AST in CM group were significantly lower than those of CIH group[(52.2±8.6) vs (112.1±31.7) U/L, (148.1±20.4) vs (295.4±39.8) U/L], the contents of liver MDA in CM group was notably lower than those of CIH group[(4.5±0.7) vs (7.9±1.1) nmol/mgprot], the activities of liver T-SOD and GSH in CM group were significantly higher than those of CIH group[(226.9±38.9) vs (181.6±28.6) U/mgprot, (10.3±1.7) vs (5.5±1.3) mg/gprot](all P<0.05). Compared with CIH group, declining tendency was observed from contents of NF-κB in CM group, but there was no statistical difference[(15.8±2.1) vs (16.2±3.3) ng/L, P>0.05]. Pathology observation showed the CIH group had abundant inflammatory cells infiltration in the liver portal area and the inflammatory cells infiltration decreased following Chinese medicine treatments. Conclusion: Yiqi Huatan Quyu prescription has some protection to CIH rat liver, which might mediate by the reduction of oxidative stress and inflammatory mediator.

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.

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.

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

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.

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.

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.

Analysing the relations between TCM syndrome differentiation type and pathology in 312 patients with gastric cancer, the authors put forward the syndrome differentiation type of deficiency of vitality and excess in superficiality. The studies showed that the four syndrome types of deficiency of vitality such as Spleen-Stomach deficiency, Qi-Xue deficiency, Yin deficiency and inner heat, Spleen-Kidney Yang deficiency and the three syndrome types of excess in superficiality such as Liver-Stomach disorder, blood stasis and stagnation of Qi, Phlegm-dampness and stagnation of toxic. The same changes in pathologic characteristic of both were from early to late stage, the infiltration getting deeper, the tumor getting larger and the metastasis of lymph nodes around the stomach from little to much. Their difference was that in the deficiency of vitality syndrome-type, the chief manifestation was in nest or spread infiltration type which became serious by degrees, whereas in excess in superficiality type, the reaction of lymphoidocytes around the cancer was decreasing. The studies also showed that in most syndrome types of Spleen-Kidney Yang deficiency and Phlegm-dampness and stagnation of toxic, the tumor occurred in wide-range and the degree of tissue differentiation was quite low. The authors suggested that there might be morphopathologic basis in TCM syndrome differentiation types and the conclusion has practical value in guiding clinics.

The syndromes among 674 cadres over 45 years in age with case-control study were investigated, and the TCM susceptible factors (TCM-SF) of senile lipid metabolic disturbance (SLMD) were analysed statistically, which indicated that Kidney-Deficiency, Phlegm-Turbid and Blood-Stasis were the main TCM-SF for SLMD. Compared with the results of presenility, it indicated that the Deficiency in origin was the intrinsic factors in development of LMD in presenile and senile period. Among which, Kidney-Deficiency possibly was the main factor. It is inferred the Deficiency in origin might cause the LMD in presenile and senile stage, and develop gradually as Syndrome of Deficiency in origin and Excess in superficiality, the latter aggravate the former as well. Both of these two Syndromes in origin affected the process of lipid metabolism. The results provided the prevention and treatment of SLMD, for further exploring the pathogenic factor and pathogenesis of the disease.

In 743 cases, the TCM and WM susceptible factors of senile cataract (SC) was studied by the clinical epidemiological investigation. By single factor analysis, the result showed that in WM, the susceptible factors of SC mostly related to (1) case history: coronary heart disease, old ages, smoking, multiple offsprings; (2) physical sign: short build, with coronary sulcus, higher systolic pressure, pulse pressure and average arterial pressure; (3) cardiovascular function: abnormal EKG, higher heart beat index, short microcirculatory stasis time, lower carrier viscosity of blood; (4) dysfunction of brain; (5) deficiency of pulmonary function; (6) lower RBC ATPase, higher whole blood reduction viscosity. While in TCM, it was related to (1) old aged and general asthenia, (2) deficiency of Qi, Heart, Liver or Kidney, (3) Blood Stasis. By stepwise regression analysis, the result showed that SC occurred through the combination with 13 factors of TCM and WM, including Yin Deficiency, senility index, hemorheology index, brain function, pulmonary function, blood pressure, body height, character, optical fundus, etc.
