ABSTRACT
AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.
ABSTRACT
Objective To analyse the prognosis and risk factors of lung cancer with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Tongchuan City, and to provide a theoretical basis for improving the prognosis of patients with lung cancer complicated with AECOPD. Methods A total of 280 patients with lung cancer combined with AECOPD admitted to Tongchuan People's Hospital from January 2021 to August 2022 were selected and divided into survival group and death group according to whether the patients survived during hospitalization. Serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA 21-1) and other tumor markers were compared between the two groups. Lung function was measured by lung function instruments, and the levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC and other lung function indicators were compared between the two groups. The patients' clinical data were collected from the medical record system, and univariate analysis and logistic regression were used to analyze the independent risk factors affecting the prognosis of patients with lung cancer complicated with AECOP. Results The values of FEV1, FVC and FEV1/FVC in the death group were significantly lower than those in the survival group (P<0.05). Serum CEA and CYFRA 21-1 levels in the death group were significantly higher than those in the survival group (P<0.05). Multiple logistic regression analysis showed that albumin level <35 g/L (OR=2.728), TNM stage III to IV (OR=2.416), multidrug-resistant bacterial infection (OR=2.982), and GOLD grade III to IV (OR=3.417) were independent risk factors for death in patients with lung cancer complicated with AECOPD in Tongchuan City (P<0.05). Conclusion Patients with lung cancer complicated with AECOPD in Tongchuan City have a high risk of death during hospitalization, especially patients with TNM stage III to IV and GOLD grade III to IV. Multi-drug resistant bacteria infection should be actively controlled to improve the albumin level of patients, which is conducive to the prognosis of patients.
ABSTRACT
ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV1）， forced vital capacity （FVC）， one second rate （FEV1/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ2=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.
ABSTRACT
This study aimed to evaluate the effectiveness and safety of eight oral Chinese patent medicines in the treatment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) by network Meta-analysis. Randomized controlled trial(RCT) on the treatment of AECOPD with eight oral Chinese patent medicines was retrieved from databases including CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, EMbase, and Cochrane Library from database inception to August 6, 2022. The information was extracted from the included literature and the quality of the included studies was evaluated using the Cochrane risk of bias assessment tool. The data were analyzed using Stata SE 15.1 and ADDIS 1.16.8 software. Finally, 53 RCTs were included, with 5 289 patients involved, including 2 652 patients in the experimental group and 2 637 patients in the control group. Network Meta-analysis showed that Lianhua Qingwen Capsules+conventional western medicine were optimal in improving clinical effective rate, Shufeng Jiedu Capsules+conventional western medicine in improving FEV1/FVC, Qingqi Huatan Pills+conventional western medicine in improving FEV1%pred, Feilike Mixture(Capsules)+conventional western medicine in improving PaO_2, Lianhua Qingwen Capsules+conventional western medicine in reducing PaCO_2, and Qingqi Huatan Pills+conventional western medicine in reducing C-reactive protein(CRP). In terms of safety, most of them were gastrointestinal symptoms, and no serious adverse reactions were reported. When the clinical effective rate was taken as the comprehensive index of efficacy evaluation, Lianhua Qingwen Capsules+conventional western medicine were the most likely to be the best treatment for AECOPD. There are some limitations in the conclusion of this study. It only provides references for clinical medication.

OBJECTIVE@#To observe the clinical effect of electroacupuncture (EA) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with gastrointestinal dysfunction.@*METHODS@#A total of 100 patients with AECOPD complicated with gastrointestinal dysfunction were randomly divided into an EA group (50 cases, 2 cases dropped off, 1 case excluded) and a medication group (50 cases). Both groups were treated with symptomatic and supportive treatment such as low flow oxygen, nebulized inhalation of short-acting β2 agonist (SABA) or short-acting muscarinic antagonist (SAMA) combined with inhaled corticosteroid (ICS). The EA group was treated with EA at Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Shuifen (CV 9), Tianshu (ST 25), Chize (LU 5) and Lieque (LU 7), with discontinuous wave, 2 Hz in frequency, 30 min each time, once a day. In the medication group, oral mosapride citrate tablets were given, 3 times a day, 5 mg each time. Both groups were treated for 5 d. Before and after treatment, the gastrointestinal symptom rating scale (GSRS) score was observe, serum procalcitonin (PCT), C-reactive protein (CRP), and plasma oxygenation index (PaO2/FiO2) were detected, and patient satisfaction degree was evaluated in the two groups.@*RESULTS@#Compared with before treatment, except for diarrhea dimension in the medication group, the total scores and each dimension scores of GSRS were decreased (P<0.05), serum PCT and CRP were decreased (P<0.05), plasma PaO2/FiO2 was increased (P<0.05) in the two groups after treatment. After treatment, in the EA group, the total score and abdominal pain, dyspepsia, constipation and diarrhea scores of GSRS were lower than those in the medication group (P<0.05), meanwhile serum PCT and CRP were lower and plasma PaO2/FiO2 was higher than those in the medication group (P<0.05). The improvement of gastrointestinal symptoms, life quality and overall satisfaction degree in the EA group were superior to those in the medication group (P<0.05).@*CONCLUSION@#EA could improve the symptoms of patients with AECOPD complicated with gastrointestinal dysfunction, reduce inflammatory response, improve oxygenation and patient satisfaction degree.

@#BACKGROUND: To investigate the effects of early standardized enteral nutrition (EN) on the cross-sectional area of erector spine muscle (ESMcsa), plasma growth differentiation factor-15 (GDF-15), and 28-day mortality of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with invasive mechanical ventilation (MV). METHODS: A total of 97 AECOPD patients with invasive MV were screened in the ICUs of the First People's Hospital of Lianyungang. The conventional EN group (stage I) and early standardized EN group (stage II) included 46 and 51 patients, respectively. ESMcsa loss and GDF-15 levels on days 1 and 7 of ICU admission and 28-day survival rates were analyzed. RESULTS: On day 7, the ESMcsa of the early standardized EN group was significantly higher than that of the conventional EN group, while the plasma GDF-15 levels were significantly lower than those in the conventional EN group (ESMcsa: 28.426±6.130 cm2 vs. 25.205±6.127 cm2; GDF-15: 1661.608±558.820 pg/mL vs. 2541.000±634.845 pg/mL; all P<0.001]. The 28-day survival rates of the patients in the early standardized EN group and conventional EN group were 80.40% and 73.90%, respectively (P=0.406). CONCLUSION: ESMcsa loss in AECOPD patients with MV was correlated with GDF-15 levels, both of which indicated acute muscular atrophy and skeletal muscle dysfunction. Early standardized EN may prevent acute muscle loss and intensive care unit-acquired weakness (ICU-AW) in AECOPD patients.
ABSTRACT
ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.
ABSTRACT
Objective To analyze the positive rate of serum mycoplasma pneumoniae antibody IgM in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Liangjiang New Area of Chongqing and the related risk factors, so as to provide a theoretical basis for clinical diagnosis and treatment of AECOPD. Methods Retrospective analysis of 728 cases of AECOPD patients from January 2020 to December 2021 in Chongqing Liangjiang New Area Third Class Hospital. ELISA was used to determine Mycoplasma pneumoniae IgM antibodies. According to the detection of Mycoplasma pneumoniae IgM antibodies, the patients were divided into infection group and non-MP infection group. Clinical data such as gender, age, length of stay, place of residence, smoking status, home oxygen therapy, GOLD grade of COPD, number of acute exacerbations in the previous year, mechanical ventilation, and application of anti-infective drugs were collected. Univariate analysis and logistic regression were used to analyze the risk factors of MP infection in AECOPD patients. Results The positive rate of MP-IgM in 728 AECOPD patients was 15.38% (112/728), including 67 males and 45 females. There was no significant difference in the positive rate of MP-IgM in AECOPD patients between different seasons (χ2=2.840, P>0.05). Age ≥60 (OR=3.243), smoking (OR=2.559) and GOLD grade 3-4 (OR=3.760) were independent risk factors for MP infection in AECOPD patients. Conclusion The incidence of MP infection in AECOPD patients in Liangjiang New Area of Chongqing is relatively high, especially in AECOPD patients with age ≥ 60, smoking, GOLD grade 3-4, which should be warned of the possibility of mycoplasma pneumoniae infection , and targeted treatment measures can improve the cure rate.
ABSTRACT
Objective:To explore the predictive value of exhaled nitric oxide (FeNO) for the risk of acute exacerbation in stable chronic obstructive pulmonary disease (COPD) patients over the next year and evaluate whether it can guide the use of inhaled corticosteroids (ICS).Methods:This study was a multicenter, retrospective and observational cohort study. The subjects of this study were stable COPD patients who were hospitalized in 12 hospitals in Hunan Province and Guangxi from January 2017 to December 2021. The patient′s basic Demography information, previous acute exacerbation history, pulmonary function, FeNO, chronic obstructive pulmonary disease assessment test questionnaire (CAT) score, modified British Medical Research Council dyspnea questionnaire (mMRC) score, chronic obstructive pulmonary disease control questionnaire (CCQ) score, and detailed treatment plan were collected. Based on FeNO 25 ppb, patients were divided into a high FeNO group and a normal FeNO group. All patients were followed up for 1 year and information on acute exacerbation was recorded.Results:A total of 825 patients were included, aged (63.5±9.1)years, with a median of 25 ppb of FeNO. A number of 825 patients were followed up for 1 year, of which 262(31.8%) experienced acute exacerbation. Multivariate logistic regression found that FeNO, CAT score, smoking cessation, and past history of acute exacerbation were independent factors predicting acute exacerbation in COPD patients in the next year (all P<0.05). High FeNO was a protective factor for acute exacerbation in COPD patients in the next year, with an OR value of 0.10 ( P<0.001). Further analysis found that the proportion of patients in the high FeNO group using ICS was significantly higher than that in the normal FeNO group [58.8%(247/420) vs 48.6%(197/405), P=0.003]. In the high FeNO group, using ICS can reduce the incidence of acute exacerbation of COPD in the next year [8.9%(22/247) vs 15.6%(27/173), P<0.05], while in the normal FeNO group, there was no statistically significant difference in the frequency of acute exacerbation between patients using ICS and those not using ICS ( P>0.05). Conclusions:FeNO is an independent factor predicting the acute exacerbation of COPD in the next year, and patients with high FeNO levels may consider using ICS in combination.
ABSTRACT
Objective:To explore the risk factors of acute exacerbation (AE) of chronic obstructive pulmonary disease (COPD) and whether Eosinophil (EOS) in peripheral blood can guide the treatment of inhaled corticosteroids (ICS).Methods:This study was a single center, Prospective cohort study. The subjects of this study were from stable COPD patients who were treated in the Department of Respiratory Medicine of the Xiangya Second Hospital of Central South University from January 2020 to December 2021. Patient general information, past year AE status, exposure risk factors, modified version of the British Medical Research Council Respiratory Difficulty Questionnaire (mMRC) score, Chronic Obstructive Pulmonary Disease Assessment Questionnaire (CAT) score, ICS usage, lung function, blood routine, etc. were collected. We followed up the patient for one year. During the follow-up period, the clinical characteristics of patients with and without AE were compared to analyze the correlation between blood EOS and ICS use.Results:The median blood EOS of 617 stable COPD patients was 0.13×10 9/L, 289 patients (46.8%) with chronic obstructive pulmonary disease had a history of AE, and 207 patients (33.5%) experienced AE during 1-year follow-up. The results of univariate analysis showed that the future occurrence of AE in COPD was correlated with body mass index (BMI), AE history, Global Initiative for Chronic Obstructive Lung Disease (GOLD) grading, GOLD grouping, mMRC score, and CAT score (all P<0.05). The results of logistic multiple factor regression analysis showed that patients with BMI<24 kg/m 2, AE in the past year, severe AE in the past year, smoking history and other exposure factors, GOLD level 2 or above, GOLD C and D groups, and mMRC score≥ 2 had a higher risk of future AE (all P<0.05). There was no statistically significant difference in the incidence of AE between patients with COPD with different levels of EOS and those without ICS during a 1-year follow-up period (all P>0.05). Conclusions:The past 1-year AE history, BMI, exposure risk factors, degree of airflow restriction, and respiratory symptoms of patients with chronic obstructive pulmonary disease can predict future AE risk. There is no significant difference in future AE risk among patients with different levels of EOS, and EOS cannot guide ICS treatment to reduce AE risk.
ABSTRACT
Objective:To analyze the association between serum leptin and the risk of acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:The clinical data of 127 COPD patients admitted to the Ninth People′s Hospital of Suzhou from November 2019 to December 2021 were retrospectively analyzed. According to whether acute exacerbation occurred in COPD patients, they were divided into acute exacerbation group (35 cases) and stable group (92 cases). General data of all patients were collected, including gender, age, body mass index (BMI), education level, disease course, smoking history, hypertension, diabetes, pneumonia, asthma and treatment methods. The forced expiratory volume in the first second/forced vital capacity (FEV 1/FVC), partial pressure of carbon dioxide (PCO 2), arterial blood pH and laboratory indicators [serum leptin, tumor necrosis factor (TNF-α) and C-reactive protein (CRP) levels] were detected. Receiver operating characteristic (ROC) curve was used to analyze the value of serum leptin, TNF-α and CRP in predicting acute exacerbation in COPD patients, and non-conditional logistic stepwise regression was used to analyze the risk factors of acute exacerbation in COPD patients. Results:Compared with the stable group, the proportion of patients with BMI<18.5 kg/m 2, complicated with pneumonia and asthma was higher, and the levels of serum leptin, TNF-α and CRP were also higher in acute exacerbation group (all P<0.05); ROC analysis showed that leptin≥3.683 ng/ml, TNF-α≥95.746 pg/ml and CRP≥22.405 mg/L were the best cut-off values of acute exacerbation in COPD patients(all P<0.05). Logistic regression analysis showed that BMI<18.5 kg/m 2, combined pneumonia, combined asthma, leptin≥3.683 ng/ml, TNF-α≥95.746 pg/ml, CRP≥22.405 mg/L were the risk factors for acute exacerbation of COPD patients(all P<0.05). Conclusions:Serum leptin level is elevated in COPD patients, and elevated serum leptin can lead to increased risk of acute exacerbation of COPD. In addition, low BMI, combined pneumonia or asthma, abnormally elevated TNF-α and CRP may be risk factors for acute exacerbation of COPD patients.
ABSTRACT
OBJECTIVE@#To study epidemiological characteristics and hospitalization costs of female inpatients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Beijing.@*METHODS@#A retrospective study was conducted to analyze electronic hospitalization summary reports of female inpatients with AECOPD in Beijing from 2013 to 2020. Clinical characteristics (age distribution and comorbidities), epidemiological characteristics (temporal and spatial distribution characteristics), hospi-talization times and costs of patients were described.@*RESULTS@#A total of 57 911 subjects in 166 hospitals were included in this study, with a mean age of (78.84±8.59) years and the highest number of patients aged 80-89 years (49.06%), followed by patients aged 70-79 years (31.08%), and the lowest number of patients under 50 years (0.41%). The proportions of patients with coronary heart disease, hypertension and heart failure were 30.60%, 30.52% and 26.54% respectively. The median number of daily hospitalizations during the study period was 18 (IQR: 16). The number of daily hospitalizations for AECOPD showed an overall growth trend over the eight years from 2013 to 2020, starting to increase significantly in 2015 and continuing to increase until 2019, then followed by a decline in 2020. The proportion of inpatient admissions was higher in winter and spring (54.09%) than that in summer and autumn (45.91%). The top three districts in terms of the proportion of total inpatient admissions were Xicheng district (14.18%), Chaoyang district (14.12%) and Fengtai district (13.47%). The density of inpatients was relatively high in the western regions, central urban areas and northeastern regions of the city, while the density of inpatients was relatively low in the near suburbs. The median number of hospital days for female patients with AECOPD was 12 days, and the median hospital costs was CNY 20 648.37. Patients from urban areas had longer hospitalization times and higher hospitalization costs than those from suburban areas (P < 0.001). Western medicine expenses accounted for the largest proportion of total hospital expenses (33.32%). During the study period, hospitalization costs exhibited an overall pattern of initial growth, followed by subsequent decline, eventually stabilizing. The differences in hospitalization costs among the patients with different comorbidities were significant.@*CONCLUSION@#Female hospitalized patients with AECOPD in Beijing were older than 70 years, often complicated by cardiovascular disease. AECOPD occurred mainly in winter and spring, with regional differences. The hospitalization costs were closely associated with the patients' age, comorbidities, and the geographicical region.

BACKGROUND@#Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is an important occurrence in the natural history of idiopathic pulmonary fibrosis (IPF), associated with high hospitalization rates, high mortality and poor prognosis. At present, there is no effective treatment for AE-IPF. Chinese herbal medicine has some advantages in treating IPF, but its utility in AE-IPF is unclear.@*OBJECTIVE@#The treatment of AE-IPF with Kangxian Huanji Granule (KXHJ), a compound Chinese herbal medicine, lacks an evidence-based justification. This study explores the efficacy and safety of KXHJ in patients with AE-IPF.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#We designed a randomized, double-blind, placebo-controlled, exploratory clinical trial. A total of 80 participants diagnosed with AE-IPF were randomly assigned to receive KXHJ or a matching placebo; the treatment included a 10 g dose, administered twice daily for 4 weeks, in addition to conventional treatment. Participants were followed up for 12 weeks after the treatment.@*MAIN OUTCOME MEASURES@#The primary endpoints were treatment failure rate and all-cause mortality. Secondary endpoints included the length of hospitalization, overall survival, acute exacerbation rate, intubation rate, the modified British Medical Research Council (mMRC) score, and the St George's Respiratory Questionnaire for IPF (SGRQ-I) score.@*RESULTS@#The rate of treatment failure at 4 weeks was lower in the intervention group compared to the control group (risk ratio [RR]: 0.22; 95% confidence interval [CI]: 0.051 to 0.965, P = 0.023). There was no significant difference in all-cause mortality at 16 weeks (RR: 0.75; 95% CI: 0.179 to 3.138; P > 0.999) or in the acute exacerbation rate during the 12-week follow-up period (RR: 0.69; 95% CI: 0.334 to 1.434; P = 0.317). The intervention group had a shorter length of hospitalization than the control group (mean difference [MD]: -3.30 days; 95% CI, -6.300 to -0.300; P = 0.032). Significant differences in the mean change from baseline in the mMRC (between-group difference: -0.67; 95% CI: -0.89 to -0.44; P < 0.001) and SGRQ-I score (between-group difference: -10.36; 95% CI: -16.483 to -4.228; P = 0.001) were observed after 4 weeks, and also in the mMRC (between-group difference: -0.67; 95% CI: -0.91 to -0.43; P < 0.001) and SGRQ-I (between-group difference: -10.28; 95% CI, -15.838 to -4.718; P < 0.001) at 16 weeks. The difference in the adverse events was not significant.@*CONCLUSION@#KXHJ appears to be effective and safe for AE-IPF and can be considered a complementary treatment in patients with AE-IPF. As a preliminary exploratory study, our results provide a basis for further clinical research.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR1900026289).

Objective To analyze the relationship between acute exacerbation of chronic obstructive disease (COPD) hospitalization and climate change in Enshi, Hubei province, and to provide theoretical basis for the prevention and treatment of COPD in Enshi . Methods Patients with acute COPD in Enshi district of Hubei Province from January 2019 to December 2019 were selected, and the clinical data of all patients on admission, including symptoms, signs, onset month, lung function indicators and serum inflammatory factors, were analyzed . FEV1% predictive value, FEV1/FVC and other lung function indexes were determined by pulmonary function detector. CRP and WBC levels were determined by biochemical detector. At the same time, meteorological factors data in Enshi , were collected , including monthly mean temperature, monthly mean humidity, monthly mean wind speed , monthly mean sunshine in Hubei province , etc. Spearman linear correlation was used to analyze the meteorological factors affecting the number of hospitalized AECOPD patients . Results The age of patients with ACUTE exacerbation of COPD was mainly 70-79 years old (34.63%) in Enshi area of Hubei Province , followed by 60-69 years old (22.49%) , and the lowest was 40-49 years old (13.75%). The incidence time mainly concentrated to may for the peak in March , November to January for the secondary peak , June to October for a relatively small number of cases. The main symptoms of COPD acute recombination are frequent cough , shortness of breath , increased sputum volume, etc., while the main signs are emphysema , wheezing , dry and wet rales . The predictive value of FEV1 and FEV1/FVC value of acute recombinant COPD were significantly lower than those of non-acute recombinant COPD (P1=-0.519 , r2=-0.428, P1=0.124 , r2=0.176, P>0.055) . Conclusion The number of patients with ACUTE exacerbation of COPD shows obvious seasonality, and the occurrence of AECOPD should be actively prevented in months with great changes in temperature and humidity.
ABSTRACT
After systematically reviewing the syndrome distribution， evolution， diagnostic criteria， effectiveness evaluation and genomics study on acute exacerbation of chronic obstructive pulmonary disease （AECOPD） in the past decade， we found that there are problems such as inconsistency in the nomenclature of syndrome， lack of quantitative diagnostic tools for syndrome， less developed evaluation tools for syndrome efficacy， and singularity of genomics technique. Based on this， it was proposed that we should pay attention to the standardisation of syndrome naming， strengthen the research on quantitative diagnostic methods， establish standardised and quantitative diagnostic tools， further improve the existing assessment tools of syndrome effectiveness， and integrate the existing genomics techniques to conduct research， so as to support the further research on AECOPD syndromes.
ABSTRACT
ObjectiveTo analyze the effect and possible mechanism of the synergistic treatment with Qingjin Huazhuo Formula （清金化浊方， QHF） on the occurrence of thrombotic events in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease （AECOPD） and phlegm heat stasis obstructing in the lung syndrome. MethodsIn a retrospective cohort study， 305 AECOPD inpatients with the syndrome of phlegm heat stasis obstructing in the lung were included. According to whether using QHF （the course of treatment ≥ 7 days）， they were divided into the exposure group （193 cases） and the non-exposure group （112 cases）. Totally， 109 pairs of cases were obtained by 1∶1 propensity score matching （PSM）. After matching， the occurrence of thrombotic events during hospitalization， the remission of main symptoms or signs （including cough， expectoration， wheezing， cyanosis） after 10 days （±3 days） of treatment， and the difference of the indicators including D-dimer， percentage of neutrophils （NEUT%）， C-reactive protein （CRP）， arterial partial pressure of oxygen （PaO2）， and arterial partial pressure of carbon dioxide （PaCO2） before treatment and after 10 days （±3 days） of treatment during the first auxiliary examination. ResultsAfter matching， the incidence of thrombotic events during hospitalization in the exposure group （5 cases， 4.59%） were lower than that of the non-exposure group （15 cases， 13.76%， P＜0.05）. The exposure factor that taking QHF for 7 days or above was a protective factor for thrombotic events in AECOPD hospitalized patients with phlegm heat stasis obstructing in the lung syndrome （RR = 0.333， 95% CI 0.126 to 0.885）. The remission rates of cough （100/109， 91.74%）， expectoration （103/109， 94.50%）， wheezing （102/109， 93.58%）， and cyanosis （97/109， 88.99%） in the exposure group were significantly higher than those in the non-exposure group （90/109， 82.57%； 94/109， 86.24%； 89/109， 81.65%； 86/109， 78.90%） after treatment （P＜0.05）. After treatment， the levels of D-dimer， NEUT%， CRP and PaCO2 in both groups significantly decreased （all P＜0.05）， and the level of PaO2 significantly increased （P＜0.05）. The difference of the levels of D-dimer， NEUT% and PaO2 in the exposure group before and after treatment were larger than those in the non-exposure group （P＜0.05）， while the pre-post difference of CRP and PaCO2 were not significantly different between the two groups （P＞0.05）. ConclusionThe synergistic treatment with QHF can effectively reduce the occurrence of thrombotic events， alleviate the clinical symptoms or signs such as cough， expectoration， wheezing， and cyanosis， and can improve lung function in hospita-lized patients with AECOPD and phlegm heat stasis obstructing in the lung syndrome. Its mechanism may be related to improving blood coagulation and inflammatory status.
ABSTRACT
Background: Chronic obstructive pulmonary disease (COPD) is not only a respiratory disease but is also a systemic disease associated with comorbidities such as diabetes mellitus (DM), hypertension, osteoporosis, etc. Diabetes being one of the comorbidities, COPD is thought to be a causative factor for developing insulin resistance. Similarly, poor glycemic control is associated with worsened COPD outcomes. Thus, this study has been taken up to analyze the effect of hyperglycemia on the duration of hospital stay and rate of mortality, and other outcomes in patients with COPD with exacerbation. Methods: It was an observational study conducted for 1 year in KLES Dr. Prabhakar Kore Hospital & Medical Research Centre, Belagavi, Karnataka, India. A total of 84 patients were enrolled and divided into two groups based on the mean random blood sugar (RBS) levels. Group I had 40 patients with mean RBS <250 mg/dL and group II had 44 patients with mean RBS ?250 mg/dL. Outcomes and variables of the patients with COPD were compared between both groups. Results: Patients in group II had poor outcomes compared to group I. The mean duration of hospital stays in groups I and group II were 5.43 and 7.34, respectively, with a significant p < 0.0001. The mean duration of intensive care unit (ICU) stay was 3.33 and 4.47 in groups I and II, respectively, which was statistically significant. The rate of mortality in groups I and II was 5.00 and 11.36%, respectively. Conclusion: Patients with hyperglycemia had an increased duration of hospital stay and rate of mortality. Optimal glycemic control plays a significant role in patients with COPD in reducing the severity of exacerbation and mortality.

Conclusions:Male patients are more prone to phlegm and turbidities than female patients. PCT and D-D were the main risk factors of phlegm-heat obstruction syndrome. Elevated hemoglobin is a risk factor for patients with phlegm stasis and lung syndrome. Heart function classification is the main risk factor of phlegm-dampness-stasis heat syndrome.
ABSTRACT
ObjectiveIn view of the problems of large errors and poor accuracy in pulmonary function testing in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), a predictive classification model of pulmonary function in patients with AECOPD was proposed by comparing the prediction performance of different machine learning models to find the optimal model. MethodsFrom January, 2018 to February, 2020, 90 patients with different degrees of COPD from the Affiliated Suzhou Science and Technology Town Hospital of Nanjing Medical University were collected. Six machine learning model algorithms (K-nearest neighbor, logistic regression, support vector machine, naive Bayes, decision tree and random forest) were used to establish AECOPD predictive classification models. Their area under the curve of receiver operating characteristic (AUC-ROC) and accuracy were compared. Ten-fold cross-validation method was used to validate the data set. ResultsThe model based on random forest worked best in predicting and classifying AECOPD patients, with an accuracy rate of 0.844 and an AUC-ROC of 0.916. ConclusionRandom forest-based predictive model is a powerful tool for identifying patients with AECOPD, providing decision support when it is difficult to give a definitive diagnosis.
