Lung function, mMRC score, CAT score, and comorbidity index were not different between the groups. The annual rate of all exacerbations and severe exacerbations required hospital admission were not different between ACO and COPD alone (0.20 vs 0.14, 0.12 vs 0.10, events per person, respectively). Mortality was significantly higher in patients with COPD alone compared with those with ACO during the study period (P=0.037).

The results of our study indicate that ACO is not associated with poor clinical features nor outcomes in an outpatient COPD cohort receiving appropriate treatment.

The forced mid-expiratory flow (FEF

) value is a potentially sensitive marker of obstructive peripheral airflow. We aimed to assess whether FEF

can be an early predictor of chronic obstructive pulmonary disease (COPD).

Between July 1, 2007 and June 31, 2009, we identified 3624 patients who underwent a pulmonary function test (PFT) in Gangnam Severance Hospital. We selected 307 patients aged over 40 years without COPD who had normal PFT results at baseline and who had follow-up PFT records more than 1 year later. A FEF

z-score less than-0.8435was considered low. We defined COPD as a forced expiratory volume in one second/forced vital capacity value of less than 0.7 before July 31, 2019.

Among 307 patients, 91 (29.6%) had lowFEF

at baseline. After 10 years, the incidence rate of COPD in the low FEF

group was significantly higher than that in the normal FEF

group (41.8% vs 7.4%;

<0.001). The Cox proportional hazard model showed that age (hazard ratio [HR]1.09;

-value<0.001), smoking status (occasional smoker HR, 4.59;

-value<0.001and long-term smoker HR, 2.18;

-value=0.023), and lowFEF

(HR, 3.31;

-value<0.001) were predictive factors for the development of COPD.

The FEF

value in patients with normal lung function is a useful predictor for the development of COPD. We should carefully monitor patients who present with low FEF

values, even if they have normal lung function.

The FEF25-75% value in patients with normal lung function is a useful predictor for the development of COPD. We should carefully monitor patients who present with low FEF25-75% values, even if they have normal lung function.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an essential occurrence in COPD management and is the leading cause of morbidity and mortality. Chinese herbal medicine is widely used in the treatment of AECOPD, but high quality randomized controlled trials are limited. This study aimed to evaluate the efficacy and safety of Chinese herbal medicine as adjuvant therapy for patients with AECOPD.

This was a randomized, double-blind, placebo-controlled study of 378 participants from eight centers in China. Participants were randomly assigned to receive 10 g of Chinese herbal medicine (according to the type of Traditional Chinese medicine syndrome Sanhanhuayin, Qingrehuatan, or Zaoshihuatan granules) or placebo, two times per day, for 14 days, in addition to conventional medicine. Participants were followed up for 84 days after the treatment. The primary end point was the COPD assessment test (CAT) score. Secondary end points included the Modified British Medical Research Council (mMRC) 0.892; P=0.010), and significantly lower number of readmissions due to AECOPD (RR, 0.41; 95% CI, 0.193 to 0.865; P=0.015). Significant differences in the number of treatment failures or successes, deaths, and intubation were not observed. The difference in safety variables and adverse events between the two groups was not observed.

Chinese herbal medicine appears to be safe and beneficial for AECOPD and can be considered a complementary treatment for patients with AECOPD.

Sepsis-associated intestinal injury has a higher morbidity and mortality in patients with sepsis, but there is still no effective treatment. Our research team has proven that inhaling 2% hydrogen gas (H

) can effectively improve sepsis and related organ damage, but the specific molecular mechanism of its role is not clear. In this study, isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics analysis was used for studying the effect of H

on intestinal injury in sepsis.

Male C57BL/6J mice were used to prepare a sepsis model by cecal ligation and puncture (CLP). The 7-day survival rates of mice were measured. 4-kd fluorescein isothiocyanate-conjugated Dextran (FITC-dextran) blood concentration measurement, combined with hematoxylin-eosinstain (HE) staining and Western blotting, was used to study the effect of H

on sepsis-related intestinal damage. iTRAQ-based liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was used for studying the proteomics assocntestinal protection of sepsis. H

-related differential proteins were notably enriched in the following signaling pathways, including thyroid hormone synthesis signaling pathway, nitrogen metabolism signaling pathways, digestion and absorption signaling pathways (vitamins, proteins and fats). H

reduced intestinal injury in septic mice by down-regulating the expressions of SAA1, NDRG1, DMBT1 and IRS2.

A total of 199 differential proteins were related with H2 in the intestinal protection of sepsis.

To investigate the comparative effectiveness of certain biological injectable stimulants for the healing of skin wounds and criteria for its assessment.

A comparative study of the effectiveness of mesenchymal stem cells (SC group), collagen (Collagen group), and deproteinized calf blood hemoderivative (DCBH group) was carried out using an acute wound model. https://www.selleckchem.com/products/ly3522348.html Control wounds were injected with isotonic sodium chloride solution (Control group). A total of four groups (28 wounds per group) were included in the study. Aged male Wistar rats were used as experimental animals. A dynamic assessment of the wound areas and edges, microvasculature assessment via laser Doppler flowmetry, histological and morphometric analyses to determine the quantitative and qualitative fibroblasts composition, as well as the degree of newly synthesized collagen maturity, was conducted on days 0, 3, 7, and 14.

The administration of SCs provided a rapid but short-lasting effect, whereas the administration of collagen resulted in a delayed but long-lasting wound-healing effect.
