To explore the clinical significance of the combined detection of Clara cell secretory protein 16 (CC16) and soluble receptor for advanced glycation end product (sRAGE) in the diagnosis and prognosis of acute respiratory distress syndrome (ARDS).

100 ARDS patients admitted to the intensive care unit (ICU) of Chu Hsien-I Memorial Hospital of Tianjin Medical University from July 2019 to September 2020 were enrolled as the ARDS group, and 100 non-ARDS patients admitted to the ICU during the same period were enrolled as the control group. The general information, vital signs, blood gas analysis, serum CC16 and sRAGE levels, duration of mechanical ventilation, length of ICU stay and prognosis during hospitalization were collected. The receiver operating characteristic (ROC) curve was drawn and the area under ROC curve (AUC) was calculated to evaluate the clinical value of CC16 and sRAGE lonely or combination in the diagnosis and prognosis of ARDS.

The duration of mechanical ventilation in the ARDS group was ve clinical value for the diagnosis and prognosis of ARDS. The combined detection of them is superior to individual detection for early prediction of ARDS and prognosis.

To establish a risk prediction model for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) using regression analysis and verify the model.

The risk factors and acute exacerbation of 1 326 patients with chronic obstructive pulmonary disease (COPD) who entered the stable phase and followed up for 6 months in the four completed multi-center large-sample randomized controlled trials were retrospectively analyzed. Using the conversion-random number generator, about 80% of the 1 326 cases were randomly selected as the model group (n = 1 074), and about 20% were the verification group (n = 252). The data from the model group were selected, and Logistic regression analysis was used to screen independent risk factors for AECOPD, and an AECOPD risk prediction model was established; the model group and validation group data were substituted into the model, respectively, and the receiver operating characteristic (ROC) curve was drawn to verify the effectiveness of the risk prediction model in predi decision in a certain degree.
The AECOPD risk prediction model based on the regression analysis method had a moderate predictive power for the acute exacerbation risk of COPD patients, and could assist clinical diagnosis and treatment decision in a certain degree.
To investigate the possible mechanism of mesenchymal stem cells (MSC) secreting hepatocyte growth factor (HGF).

(1) C57BL/6 mouse mesenchymal stem cells (mMSC) were cultured in vitro, and mMSC with high expression of chemokine receptor 7 (CXCR7) were transduced by lentivirus plasmid. Blank control group and empty carrier control group were set at the same time. After 20 generations of cell culture, the transfection efficiency was identified by fluorescence microscopy and flow cytometry. The mRNA expression levels of CXCR7 in mMSC were detected by real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-PCR). (2) mMSC with passage number 4-6 were divided into MSC control group [MSC-blank group, 100 μg/L lipopolysaccharide (LPS) was added to wild-type MSC], highly expressed CXCR7 group (MSC-OE-CXCR7 group, 100 μg/L LPS was added to mMSC transduced by lentivirus plasmid with high expression of CXCR7), highly expressed CXCR7 control group (MSC-OENC-CXCR7 group, 100 μg/L LPS was aCXCR4 in MSC can increase the expression of ID-1 and promote the secretion of HGF, thus promoting pulmonary microvascular endothelial repair.
To observe the effects of berberine on procoagulant and fibrinolytic inhibitory factors produced by rat type II alveolar epithelial cell (AEC II) induced by lipopolysaccharide (LPS).

AEC II cells (RLE-6TN cells) were cultured in vitro, and the cells in logarithmic growth phase were collected. The cytotoxicity text of berberine was detected by cell counting kit-8 (CCK-8) to determine the drug concentration range according to inhibition concentration of half cells (IC
). The RLE-6TN cells were divided into five groups, the cells in blank control group were cultured in DMEM; the cells in LPS group were stimulated with 5 mg/L LPS; and the cells in berberine pretreatment groups were pretreated with 20, 50 and 80 μmol/L berberine for 1 hour, and then were co-cultured with 5 mg/L LPS. The cells were collected after LPS induced for 24 hours. The protein and mRNA expression levels of tissue factor (TF), tissue factor pathway inhibitor (TFPI) and plasminogen activator inhibitor-1 (PAI-1) in the cells were detecteds. 18.6±0.9, TAT (ng/L) 222.1±2.8 vs. 287.6±7.0, both P < 0.01].

Berberine could inhibit the LPS-induced expressions of procoagulant and fibrinolytic inhibitory factors in rat AEC II cells and promote the expressions of anticoagulant factors in a dose-dependent manner. Berberine may be a new therapeutic target for alveolar hypercoagulability and fibrinolysis inhibition in acute respiratory distress syndrome (ARDS).

To explore the effect of different tidal volumes (VT) on the hemodynamics of right heart in acute respiratory distress syndrome (ARDS) rats induced by oleic acid (OA).

Sixty adult male Sprague-Dawley (SD) rats were divided into control group (n = 20), ARDS model group (n = 20), low VT (LVT) group (n = 10) and high VT (HVT) group (n = 10) by random number table. ARDS model was reproduced by injecting OA 0.15 mL/kg through a jugular vein. The control group was given the same amount of normal saline. The success of modeling was judged by the oxygenation index (PaO
/FiO
) 2 hours after modeling, at the same time, the lung tissues were collected, the wet/dry weight (W/D) ratio was determined, and the lung histopathological changes were measured by lung injury score. The rats in the LVT group and HVT group were given mechanical ventilation with VT of 6 mL/kg or 20 mL/kg for 4 hours, respectively at 2 hours after modeling. The rats in the control group and the ARDS model group maintained spontaneous breathing. parameters of the right ventricle and protect the function of the right heart in ARDS rats.

To investigate the effect and mechanism of exosomes derived from human-induced pluripotent mesenchymal stem cells (iMSC-Exos) on alveolar macrophages (AM) pyroptosis.

The exosomes in the culture supernatant of human-induced pluripotent mesenchymal stem cells (iMSC) were extracted by rotating ultrafiltration, and the extracted exosomes were identified by transmission electron microscopy, Western blotting and high-resolution adjustable resistance pulse. The rat alveolar macrophage cells (NR8383 cells) were cultured in vitro and the logarithmic growth phase cells were divided into three groups the control group was added with an equal volume of phosphate buffered saline (PBS) in the AM supernatant; in LPS/ATP group AM cells were stimulated with 500 μg/L LPS for 23 hours and then 5 mmol/L ATP was added for 1 hour to induce pyrolysis; iMSC-Exos group was incubated with AM and 100 mg/L iMSC-Exos for 3 hours before giving LPS and ATP. The cytotoxic activity was detected by cell counting kit-8 (CCK-8) and lactatein (cleaved caspase-1/β-actin) 0.42±0.07 vs. 1.22±0.17, both P < 0.01] and pyrolysis-related protein was significantly inhibited [GSDMD protein (GSDMD/β-actin) 0.57±0.05 vs. 1.22±0.05, P < 0.01].

iMSC-Exos successfully reversed the AM pyroptosis and inflammatory factor expression induced by LPS/ATP, which may be due to the targeted inhibition of NLRP3 inflammasome pathway, suggesting that iMSC-Exos can exert anti-inflammatory effects by inhibiting the pyrolysis of AM.

To evaluate the value of neutrophil to lymphocyte and platelet ratio (N/LPR) for predicting 28-day mortality in sepsis patients.

A retrospective analysis was conducted. The clinical data of 154 sepsis patients admitted to intensive care unit (ICU) of the Affiliated Hospital of Jiangsu University from June 2017 to June 2020 were enrolled. The time of first diagnosis of sepsis in ICU was taken as the research starting point, and the death or 28 days as the end point. The 28-day outcomes of patients were recorded. The counts of peripheral blood neutrophil (NEU), lymphocyte (LYM) and platelet (PLT) were collected from all the enrolled patients within 3 days after diagnosis of sepsis. The ratios of N/LPR and NEU/LYM (NLR) were calculated respectively. The differences of N/LPR and NLR between survival group and death group were compared. Receiver operating characteristic (ROC) curve analysis was used to analyze the value of N/LPR and NLR on predicting the 28-day mortality of sepsis patients. According to the best cut-off value of ROC curve analysis, the 28-day mortality of patients with sepsis was analyzed by subgroup analysis, and the 28-day cumulative survival of patients with sepsis was analyzed by Kaplan-Meier survival curve.
