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.

Clinical features, risk factors and treatment of type 2 diabetes mellitus in patients with acute exacerbation of chronic obstructive pulmonary disease / 中国临床药理学与治疗学

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.

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.

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.

Effects of early standardized enteral nutrition on preventing acute muscle loss in the acute exacerbation of chronic obstructive pulmonary disease patients with mechanical ventilation / 世界急诊医学杂志（英文）

@#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.

Overviews of systematic and meta-analysis on the TCM treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) / 国际中医中药杂志

Objective:To re-evaluate the methodological quality, evidence quality and reporting quality of the systematic review and meta analysis of Traditional Chinese Medicine (TCM) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:We searched the databases of CNKI, Wanfang, VIP, Cochrane Library, PubMed, EMbase, and retrieved the systematic reviews or meta-analysis literatures on the treatment of AECOPD with TCM from the establishment of the database to February 28, 2021. We applied AMSTAR2 scale and GRADE Tools, PRISMA statement to evaluate methodological quality, evidence quality and report quality.Results:A total of 15 systematic reviews were included, including 85 outcome indicators. The evaluation results of AMSTAR2 scale showed that 9 articles were low-quality methodology and 6 articles were very low-quality methodology. The GRADE results showed that the quality of evidence for 23 outcome indicators was moderate, the quality of evidence for 30 outcome indicators was low, and the quality of evidence for 32 outcome indicators was very low. The results of the PRISMA statement showed that the quality of the reporting is relatively adequate.Conclusion:TCM combined with western medicine can improve the clinical efficacy of AECOPD to a certain extent, but the methodological quality of reviews and the quality of evidence are generally low. In the future, researchers should standardize the writing of systematic reviews/meta-analysis, in order to provide clinicians with more authentic and reliable evidence-based evidence.

Assessment of diaphragmatic dysfunction by two-dimensional speckle tracking imaging in patients with acute exacerbation of chronic obstructive pulmonary disease / 中华超声影像学杂志

Objective:To explore the application value of two-dimensional speckle tracking imaging (2D-STI) in evaluating diaphragm function, and to compare the ability of 2D-STI and conventional diaphragm ultrasonography in diagnosing diaphragmatic dysfunction and evaluating disease severity in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A total of 58 AECOPD patients admitted to the First Affiliated Hospital of Xi′an Jiaotong University from January to October 2021 were retrospectively enrolled as AECOPD group, and 34 healthy subjects were recruited as control group during the same period. Repeatability test of diaphragmatic 2D-STI was performed. According to modified Medical Research Council (mMRC) dyspnea scores system and COPD Assessment Test (CAT), mMRC 0-1 and CAT<10 was classified as group A, mMRC≥2 and CAT≥10 was classified as group B. The baseline characteristics, conventional diaphragm ultrasonography parameters(thickening fraction and excursion) and 2D-STI parameters (longitudinal and radial strains) were compared between the AECOPD group and the control group, and the Spearman correlation between parameters of AECOPD group and forced expiratory volume in one second (FEV1) was analyzed. The differences of these parameters between group A and B were also compared. The ROC curve of conventional diaphragm ultrasonography parameters and 2D-STI parameters was plotted to differentiate group A from group B, and the diagnostic efficacy was evaluated.Results:Great intra- and inter-observer reproducibility was found for all diaphragmatic 2D-STI parameters, with ICCs above 0.80 for all measurements. The control group and the AECOPD group did not differ in age, sex and body mass index( P>0.05), whereas there were significant differences in smoking history, lung function, bilateral thickening fraction, excursion, longitudinal and radial strains( P<0.05). Compared with control group, patients in group A had a significant increase in diaphragm thickness ( P<0.05), while there was no significant difference in that between group B and control group ( P>0.05). The bilateral longitudinal strains, radial strains and thickening fraction of diaphragm were linearly correlated with FEV1 (right side rs=0.828, 0.794, 0.843, respectively; all P<0.001; left side rs=0.757, 0.704, 0.752, respectively; all P<0.001 ), while the correlation between excursion and FEV1 was not significant(right side rs=0.247, left side rs=0.253; all P>0.05). There were significant differences in bilateral longitudinal strains, radial strains and thickening fraction between group A and group B(all P<0.05), whereas there was no significant difference in excursion between the two groups ( P>0.05). ROC analysis showed bilateral longitudinal and radial strains had higher accuracy in distinguishing group A from group B than thickening fraction and excursion(right side AUCs 0.90, 0.84, 0.78 and 0.62, respectively; left side AUCs 0.85, 0.83, 0.77 and 0.62, respectively). Conclusions:2D-STI is a real-time noninvasive technique for diaphragm function assessment, which has high clinical value. Compared with conventional ultrasonography, 2D-STI shows more accuracy and effectiveness in diagnosing diaphragmatic dysfunction and evaluating disease severity of patients with AECOPD.

Objective:To explore the changes of peripheral blood Th17/Treg and serum cytokines in AECOPD patients with secondary pulmonary fungal infection.Methods:Selected the clinical data of 27 AECOPD patients who were admitted between January 2018 to March 2020 in the Department of Respiratory Medicine, Hai'an People's Hospital Affiliated to Nantong University with fungal infection (fungal infection group), and 58 AECOPD patients without fungal infection (non-fungal infection group) who received treatment in the hospital during the same period. Compared the general clinical data, peripheral blood Th17 and Treg cell levels, Th17/Treg ratio, interleukin-17 (IL-17), interleukin-23 (IL-23), interferon-γ (interferon-γ, IFN-γ), and transforming growth factor-β (TGF-β) levels. Meanwhile, compared the levels of Th17 and Treg cells in peripheral blood, the ratio of Th17/Treg and serum cytokines in patients with different infection severity in fungal infection group. The measurement data with normal distribution were compared by independent samplet t-test between the two groups, one-way ANOVA between multiple groups, LSD-t test for pairwise comparision, and χ 2 test for counting data. Results:In the 27 AECOPD patients with fungal infection group, the pathogen distribution was 65.52% (19/27) of candida albicans, 10.34% (3/27) of candida tropicalis,10.34% (3/27) of candida albicans, and 6.90% (2/27) of Aspergillus. The level of Th17 [(16.18±3.15) % and (12.34±2.64) %, t=5.87, P<0.001)], the ratio of Th17/Treg [(4.70±0.85) and (2.41±0.51), t=22.87, P<0.001] in Patients with fungal infection group were higher than those in the non-fungal group. The level of Treg [(3.42±0.42) % and (5.13±0.51) %, t=20.77, P<0.001] in Patients with fungal infection group was lower than those in the non-fungal group. The levels of IL-17 [(85.67±21.51) μg/L and (53.64±14.36) μg/L, t= 8.12, P<0.001], and IL-23 [(61.38±16.58) μg/L and (38.29±12.60) μg/L, t=7.10, P<0.001] in Patients with fungal infection group were higher than those in non-fungal infection group, but the levels of IFN-γ ((47.75±17.72) μg/L and (62.37±19.06) μg/L, t=3.37, P=0.001) and TGF-β ((110.34±26.03) μg/L and (131.40±35.03) μg/L, t=2.87, P=0.007) were lower than those in non-fungal infection group, and the differences were statistically significant. There were statistically significant differences in the ratio of Th17/Treg, and the levels of Th17, Treg cells and cytokine among patients with different infection severity in the fungal infection group. With the increase of infection severity, the levels of Th17 ((13.06±1.98)%, (15.94±2.11)%, (17.75±2.20)%, F=10.19, P<0.001), the ratios of Th17/Treg ((5.01±0.60), (5.66±0.69), (6.52±0.65), F=10.77, P<0.001), the levels of IL-17 ((63.39±11.64) μg/L,(78.66±12.82) μg/L, F=9.01, P=0.001), and IL-23 ((42.52±13.11) μg/L, (59.97±15.25) μg/L, (69.75±14.30) μg/L, F=7.41, P=0.003) were increase, the levels of Treg ((4.33±0.39)%, (3.32±0.42)%, (2.50±0.35)%, F=44.42, P<0.001), IFN-γ ((57.78±10.52) μg/L, (48.82±10.39) μg/L, (38.90±10.56) μg/L, F=6.50, P=0.006), TGF-β ((126.62±18.94) μg/L, (115.34±13.66) μg/L, (102.52±17.73) μg/L, F=4.25, P=0.026) were significantly decreased. Conclusion:The imbalance of Th17/Treg ratio and related serum cytokines play an important role in the process of lung fungal infection in AECOPD patients, and their imbalance is related to the severity of fungal infection. Therefore, the levels of Th17/Treg and serum cytokines should be closely monitored in AECOPD patients.

A clinical study on the wean effect of setting parameters of proportional pressure support on acute exacerbation of chronic obstructive pulmonary disease patients with difficult weaning / 中华危重病急救医学

Objective:To investigate the clinical effect of setting proportional pressure support (PPS) parameters by target tidal volume (VT) method.Methods:The study was conducted retrospectively on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients admitted to Tianjin Third Central Hospital from January 2016 to December 2020. According to the PPS parameter setting method, the patients were divided into the airway blocking group and target VT group. The baseline characteristics, initial setting values of flow assist (FA) and volume assist (VA), respiratory system parameters, and clinical outcomes were collected and compared between the two groups.Results:Fifty-nine patients were enrolled, 29 patients in the airway blocking group, and 30 in the target VT group. There was no statistically significant difference in baseline characteristics, compliance, resistance, and initial settings of FA and VA between the two groups. Compared with the target VT group, the respiratory rate (RR), mean arterial pressure (MAP), VT, and arterial partial pressure of oxygen (PaO 2) recorded 1 hour after the initial setting of the PPS parameters in the airway block method group were significantly reduced [RR (times/minute): 21.0 (18.5, 22.5) vs. 23.0 (21.0, 25.0), MAP (mmHg, 1 mmHg = 0.133 kPa): 84.0 (79.0, 90.5) vs. 90.0 (87.0, 96.2), VT (mL): 305.24±41.07 vs. 330.87±46.84, PaO 2 (mmHg): 68.0 (66.0, 73.5) vs. 74.0 (69.8, 82.5), all P < 0.05], while arterial partial pressure of carbon dioxide (PaCO 2) and oral closure pressure (P0.1) were both increased significantly [PaCO 2 (mmHg): 41.0 (39.0, 46.0) vs. 37.5 (35.0, 42.2), P0.1 (cmH 2O, 1 cmH 2O = 0.098 kPa): 1.42±0.78 vs. 0.90±0.67, both P < 0.05]. Compared with airway blocking group, the duration of weaning, ICU stay, and hospital stay in the target VT group were significantly shorter [duration of weaning (hours): 42.0 (24.0, 70.5) vs. 64.0 (30.5, 97.5), ICU stay: 10.00±3.38 to 13.28±5.41, hospital stay (days): 12.07±3.40 vs. 15.41±5.60, all P < 0.05]. There was no statistically significant difference in the invasive mechanical ventilation time, weaning failure rate, ICU mortality and in-hospital mortality between the two groups. Conclusion:This study suggested that the target TV method has the advantages of practicality, safety, convenience, and rapid to set PPS parameters than the airway block method, which shortens the duration of weaning and ICU stay, and has a good clinical prospect.

Improvement Effects of Weijing Decoction on AECOPD Model Rats and Its Mechanism / 中国药房

OBJECTIVE：To study the improvement effects of Weijing deco ction on AECOPD model rats and its possibile mechanism. METHODS ：Totally 55 male SD rats were randomly divided into normal group ，model group ，Weijing decoction low-dose and high-dose groups （8.37，16.74 g/kg，by crude drug ），dexamethasone group （positive control group ，0.09 mg/kg），with 11 rats in each group. Except for normal group ，AECOPD model was induced by cigarettes combined with lipopolysaccharide in other groups. After modeling ，normal group and model group were given constant volume of water intragastrically ，and other groups were given relevant medicine intragastrocally ，twice a day ，for 14 days. After last intragastric administration ，the serum level of IL- 1 β was determined，and pathological changes of lung tissue and bronchus were observed in each group ；mRNA expression of MMP-9 and TIMP- 1 genes in lung tissue were detected ；protein expression of Ras homologous gene family member （RhoA）， dishevelled associated activator of morphogenesis- 1（DAAM1）and hyperplasic suppress gene （HSG）in lung tissue were also determined. RESULTS ：Compared with normal group ，the levels of IL- 1β in serum，mRNA expression of MMP- 9 and TIMP-1 as well as protein expression of RhoA and DAAM 1 in lung tissue were increased significantly in the model group（P＜0.05），while protein expression of HSG in lung tissue was decreased significantly （P＜0.05）；there were many chronic inflammatory cells infiltrating around the bronchus ，some airway mucosa epithelium exfoliating ，alveolar compensatory dilation，pulmonary septal capillary dilation and hyperemia. Compared with model group ，the levels of IL- 1β in serum，mRNA expression of MMP- 9 and TIMP- 1 in lung tissue were decreased significantly in Weijing decoction high-dose group （P＜0.05）；the protein expression of RhoA and DAAM 1 in lung tissue were decreased significantly in Weijing decoction low-dose and high-dose groups（P＜0.05），while the protein expression of HSG in lung tissue was increased （P＜0.05）；the pathological changes of Weijing decoction high-dose group ，such as inflammatory cells infiltrating around the bronchus and shedding of airway mucosa ， were improved significantly ， and there was complete alveolar epithelium structure but no obvious pulmonary dilation. CONCLUSIONS：Weijing decoction can improve AECOPD model rats to certain extent ；its mechanism may be associated with down-regulating mRNA expression of MMP- 9 and TIMP -1 as well as protein expression of RhoA and DAAM 1 in lung tissue ， up-regulating protein expression of HSG in lung tissue so as to inhibit the airway remodeling.
