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.

RESUMO

OBJECTIVE: Heated and humidified high-flow nasal cannula (HFNC) therapy has been used to manage different respiratory conditions in pediatric patients. However, no review has summarized its efficacy for the management of pediatric obstructive sleep apnea (OSA). MATERIALS AND METHODS: PubMed, Embase, CENTRAL, and Google Scholar were searched for all types of studies assessing the efficacy of HFNC for pediatric OSA. We compared pre-treatment and post-treatment obstructive apnea-hypopnea index (OAHI), obstructive hypopnea index (OHI), obstructive apnea index (OAI), SPO2 nadir and SPO2 mean values in a random-effect meta-analysis model. RESULTS: Six studies reporting data of 67 pediatric patients treated with HFNC were included. Most of the data were from one-time titration. Meta-analysis revealed a statistically significant reduction in OAHI with HFNC therapy (MD: 15.58 95% CI: 8.30, 22.86 I2=77% p=0.001). Similarly, pooled analysis revealed that both OHI (MD: 12.35 95% CI: 0.78, 23.92 I2=98% p=0.04) and OAI (MD: 7.54 95% CI: 2.10, 12.98 I2=79% p=0.007) were significantly reduced with HFNC treatment. Also, HFNC led to statistically significant improvement in SPO2 nadir values (MD: -8.17 95% CI: -10.40, -5.94 I2=21% p<0.00001) but it did not change the mean SPO2 values before and after treatment (MD: -0.85 95% CI: -1.94, 0.25 I2=52% p=0.13). CONCLUSIONS: Evidence from a limited number of heterogeneous and uncontrolled titration studies indicates that HFNC improves OAHI and minimum oxygen saturation in pediatric patients with OSA. However, further research is required on the long-term efficacy and compliance of HFNC therapy with a focus on different pediatric age groups.

RESUMO

CsV_{3}Sb_{5} is a newly discovered Z_{2} topological kagome metal showing the coexistence of a charge-density-wave (CDW)-like order at T^{*}=94 K and superconductivity (SC) at T_{c}=2.5 K at ambient pressure. Here, we study the interplay between CDW and SC in CsV_{3}Sb_{5} via measurements of resistivity, dc and ac magnetic susceptibility under various pressures up to 6.6 GPa. We find that the CDW transition decreases with pressure and experience a subtle modification at P_{c1}≈0.6-0.9 GPa before it vanishes completely at P_{c2}≈2 GPa. Correspondingly, T_{c}(P) displays an unusual M-shaped double dome with two maxima around P_{c1} and P_{c2}, respectively, leading to a tripled enhancement of T_{c} to about 8 K at 2 GPa. The obtained temperature-pressure phase diagram resembles those of unconventional superconductors, illustrating an intimated competition between CDW-like order and SC. The competition is found to be particularly strong for the intermediate pressure range P_{c1}≤P≤P_{c2} as evidenced by the broad superconducting transition and reduced superconducting volume fraction. The modification of CDW order around P_{c1} has been discussed based on the band structure calculations. This work not only demonstrates the potential to raise T_{c} of the V-based kagome superconductors, but also offers more insights into the rich physics related to the electron correlations in this novel family of topological kagome metals.

RESUMO

OBJECTIVE: The aim of this study was to explore the mechanism of miR-98-5p in influencing the malignant proliferation and metastasis capacities of breast cancer cells. PATIENTS AND METHODS: Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) was used to detect the expression level of miR-98-5p and GRB2-associated-binding protein 2 (Gab2) in breast cancer samples and cells. On-line target gene prediction software and Dual-Luciferase reporter assay were used to predict and verify the target genes of miR-98-5p, respectively. Cell proliferation was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. Meanwhile, migration and invasion abilities, as well as the changes of epithelial-mesenchymal transition (EMT) after transfection were detected by transwell assay and Western blot assay, respectively. RESULTS: Compared with adjacent non-tumor tissues and MCF-10A cells, the expression level of miR-98-5p in tumor tissues and MCF-7 cells was significantly declined, whereas Gab2 was markedly up-regulated. Besides, Gab2 was predicted as a target gene of miR-98-5p. Subsequent experiments indicated that the proliferation, migration, invasion and EMT of MCF-7 cells transfected with miR-98-5p were significantly inhibited. However, up-regulation of Gab2 attenuated the biological function of miR-98-5p on malignant abilities of breast cancer cells. CONCLUSIONS: We showed that miR-98-5p served as anti-oncogene in breast cancer, which might provide a new therapeutic target for its treatment.

RESUMO

Objective: To explore the role of lung dendritic cells (DCs) and Th17/regulatory T cells (Treg) pathway in the pathogenesis of chronic obstructive pulmonary disease(COPD). Methods: COPD patients who received lobectomy from Sep. 2015 to Mar. 2016 in our hospital were enrolled and classified into non-smoking non-COPD group, smoking without COPD group and COPD group. The expression of CD(80), chemokine recepter-6 (CCR6), interleukin-17A (IL-17A) and fork-head transcription factor P3 (FoxP3) were detected by immunohistochemistry (IHC) in lung tissue. Mature DCs (mDCs), immature DCs (imDCs), Th17 cells and Treg cells in lung tissue were detected by flow cytometry (FCM) and the correlation between Th17/Treg cells with lung function was analyzed. Results: (1) The expression of CD(80) and FoxP3 in COPD group was decreased, while the expression of CCR6 and IL-17A was increased (P<0.05). (2) The percentage of mDCs and Treg in lung tissue of COPD group was significantly decreased. In contrast, the proportion of imDCs and Th17 cells in COPD group was significantly increased (P<0.05). (3) The imbalance of Th17/Treg ratio in lung tissue was seen in patients with COPD, suggesting the potential mechanism of Th17 cell-mediated proinflammatory response. (4) The percentage of Th17 cells and Th17/Treg ratio in COPD patients was negatively correlated with forced expiratory volume in the first second (FEV(1)) as a percentage of predicted value (FEV(1)% pred), forced vital capacity(FVC) as a percentage of predicted value (FVC% pred), FEV(1)/FVC. On the other hand, the percentage of Treg cells was positively correlated with FEV(1)% pred, FVC% pred, FEV(1)/FVC. Conclusions: The data in this study demonstrate the maturation disorder of dendritic cells in lung tissue of COPD patients. The imbalance of Th17/Treg ratio suggests that Th17 cell-mediated proinflammatory response may be involved in the pathogenesis of COPD.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Objective: To explore the technical advantages of artery approach in lymph node sortingofrectal cancer. Methods: Sixty patients with rectal cancer who treated in general surgery department of Henan provincial tumor hospitalfrom July 2015 to January 2016 were enrolled. Patientswere divided into two groupsrandomly.Lymph node sorting methods of control group andobservation group were the traditional method and the artery approach method respectively. The total number of lymph nodes, the average inspection number, the patients number of lymph nodes less than 12, the number of positive lymph nodes, the metastasis rate of the patients, the number of average diameter less than 5 mm, the number of the positive lymph nodes which average diameter less than 5 mm, the sorting time of lymph nodes, the total number of every stationand other indicators were collected and compared. Results: There wasa significant difference between the observation group and the control groupin the total number(553 vs 395, P<0.05), the number of positive ones(96 vs 54, P<0.05), average inspection number(18.43±5.93 vs 13.27±1.96, P=0.000), the sorting time (min) (14.1±2.5 vs 17.4±3.2, P=0.000), the average diameter less than 5 mm number(4.73±1.31 vs 1.23±1.14, P=0.000), the number of positive ones average diameter less than 5 mm(0.97±1.03 vs 0.20±0.55, P=0.010), the first(8.17±4.58 vs 5.07±1.96, P=0.000) and second station(6.57±1.87 vs 4.90±1.69, P=0.001)inspection number.The inspection number less than 12, the positive rate of lymph node, the metastatic rate of the patient and the inspection number of third station have no significant differences (all P≥0.05). Conclusion: Theartery approach method inrectal cancer lymph node inspectionhas many advantages such as simple operation, obtaining more lymph nodes and more accurate pathological staging.

RESUMO

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.

RESUMO

OBJECTIVE: To investigate the advantages of thoracoabdominal radical gastrectomy for advanced Siewert type Ⅱ adenocarcinoma of the esophagogastric junction. METHODS: Clinical data of 86 patients with Siewert type Ⅱ adennocarcinoma of the esophagogastric junction who received surgical treatment at the Henan Provincial Tumor Hospital from January 2015 to January 2016 were retrospectively analyzed. Among them, 44 patients underwent abdominal operation (abdominal group), and 42 patients underwent thoracoabdominal radical gastrectomy (thoraco-abdominal group). The operation time, lymph node number, distance between the tumor and cutting edge, amount of intraoperational blood loss, postoperative pulmonary complications, and postoperative hospital stay in the two groups were compared. RESULTS: Comparing the thoracoabdominal group with the abdominal group, the number of removed lymph nodes was 41.57±9.22 vs. 35.09±10.61 (P<0.01), the number of removed mediastinal lymph nodes was 6.38±1.50 vs. 3.52±1.42 (P<0.01), the distance between the tumor and cut edge was (5.62±0.73) cm vs. (3.30±0.85) cm (P<0.01), whereas the operation time, intraoperative blood loss, postoperative pulmonary complications, occurrence of anastomotic leakage and hospital stay were statistically not significantly different (P>0.05 for all). CONCLUSIONS: For patients with advanced Siewert type Ⅱ adenocarcinoma of the esophagogastric junction, radical gastrectomy through thoracoabdominal approach can resect a longer segment of the esophagus, dissect more mediastinal lymph nodes, and does not increase post-operative complications and extend hospital stay, thus, exhibits obvious advantages in the surgical treatment of Siewert Ⅱ adenocarcinoma of the esophagogastric junction.
