To investigate the therapeutic effect of different prone position ventilation (PPV) on patients with severe acute respiratory distress syndrome (ARDS) at high altitude.
The severe ARDS patients who met the Berlin standard admitted to the department of intensive care unit (ICU) of Qinghai Provincial People's Hospital from January 2017 to January 2020 were enrolled. 6-pentadecylsalicylic Acid The patients with classic PPV treatment (i.e. alternate prone supine position, about 16 hours per day) were included in the discontinuous PPV group; the patients with modified PPV treatment (i.e. alternate left and right prone positions 20 degree angle-30 degree angle, every 4 hours and continuous treatment for 24 hours per day) were included in the continuous PPV group. The oxygenation index (PaO
/FiO
), mechanics of breathing, ventilator parameters before treatment and 72 hours after treatment, and mechanical ventilation time, the length of ICU stay, and related complications between the two groups were analyzed.
Eighteen cases were treatemplications are did not increased in prolonged time of PPV.
Continuous PPV is more effective than discontinuous PPV in the treatment of severe ARDS patients at high altitude, and the related complications are did not increased in prolonged time of PPV.
To determine the effect of andrographolide (AD) on the expression of procoagulant and fibrinolytic inhibitory factors in rat type II alveolar epithelial cells (AEC II) stimulated by lipopolysaccharide (LPS).
The AEC II cells RLE-6TN in the logarithmic growth phase were divided into 5 groups the normal control (NC) group, the LPS group, and the 6.25, 12.5, and 25 mg/L AD groups (AD 6.25 group, AD 12.5 group, AD 25 group). The NC group was cultured with RPMI 1640 conventional medium. In the LPS group, 5 mg/L LPS was added to the RPMI 1640 conventional medium for stimulation. Cells in the AD groups were treated with 6.25, 12.5, and 25 mg/L AD in advance for 1 hour and then given LPS to stimulate the culture. The cells and cell culture supernatant were collected 24 hours after LPS stimulation. The protein and mRNA expressions of tissue factor (TF), tissue factor pathway inhibitor (TFPI), and plasminogen activator inhibition-1 (PAI-1) in cells were detected by Western blotting and real-time fluorescent quantit and the decrease of PAI-1 protein expression and PIIIP level in the supernatant were also statistically significant compared with AD 12.5 group.
Andrographolide in the dose range of 6.25-25 mg/L can dose-dependently inhibit the expression and secretion of procoagulant and fibrinolytic inhibitor-related factors in AEC II cells RLE-6TN stimulated by LPS, and promote the secretion of anticoagulant factors. 25 mg/L has the most obvious effect.

To investigate the effect and mechanism of 6-formylindolo[3,2-b]carbazole (FICZ) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice.
Male C57BL/6J mice aged 8-12 weeks were divided into 4 groups with 8 mice in each group, according to the method of simple random sampling. Sepsis-induced ALI mice model was established by intraperitoneal injection of LPS 5 mg/kg (LPS group), and phosphate buffer saline (PBS) control group (PBS group) was injected with equal volume of PBS. The LPS+FICZ group was intervened by intraperitoneal injection of 1 μg FICZ 1 hour after LPS stimuli, while the FICZ control group (FICZ group) was given the same amount of FICZ 1 hour after intraperitoneal injection of PBS. Serum and lung tissue were collected 24 hours after LPS stimuli, and the pathological changes of lung tissue were analyzed by hematoxylin-eosin (HE) staining and wet/dry weight (W/D) ratio of lung tissue. The concentrations of inflammatory factors in serum and lung tissue were detected by enzyme linkedcreased (5.38±0.10 vs. 6.60±0.30, P < 0.01), so as serum IL-6 (ng/L 15.55±3.77 vs. 32.22±3.84) and lung IL-6 mRNA expression (2
0.79±0.21 vs. 6.89±0.92, both P < 0.01). The mRNA expressions of GRP78, PERK and CHOP were also significantly decreased [GRP78 mRNA (2
) 1.90±0.16 vs. 7.55±1.29, PERK mRNA (2
) 1.68±0.20 vs. 4.54±0.89, CHOP mRNA (2
) 1.13±0.24 vs. 4.44±1.13, all P < 0.05], and the protein expressions of GRP78, PERK, ATF6 and CHOP were significantly decreased (GRP78/GAPDH 0.59±0.02 vs. 0.77±0.01, PERK/GAPDH 0.48±0.03 vs. 1.04±0.05, ATF6/GAPDH 0.51±0.03 vs. 0.65±0.01, CHOP/GAPDH 0.91±0.05 vs. 1.11±0.07, all P < 0.05).
FICZ protects LPS-induced ALI possibly via suppressing endoplasmic reticulum stress and reducing IL-6 expression in blood and lung tissue.

To explore the correlation between early inflammation indicators and the severity of coronavirus disease 2019 (COVID-19).
A retrospective study was conducted. Patients with COVID-19 admitted to Wenzhou Central Hospital from January 17 to February 14, 2020 were enrolled. The general information, chest CT before admission, the first laboratory parameters and chest CT within 24 hours after admission were collected. Patients were followed up for 30 days after the first onset of dyspnea or pulmonary imaging showed that the lesions progressed more than 50% within 24 to 48 hours (according to the criteria for severe cases) as the study endpoint. According to the endpoint, the patients were divided into two groups mild type/common type group and severe/critical group, and the differences in general information and inflammation index of the two groups were compared. Logistic regression was used to analyze the inflammation index and the severity of COVID-19. Receiver operating characteristic (ROC) curve was draw topment of severe/critical illness.
To analyze the immunotherapy and clinical characteristics of coronavirus disease 2019 (COVID-19) patients, and focus on exploring the effects of immunotherapy and mesenchymal stem cells (MSC) transplantation in the critically ill patients' treatment.
Fity-five COVID-19 patients were admitted to the Fifth People's Hospital of Wuxi from January 23rd to March 31st, 2020 as the research object. The demographic characteristics of the cases and the methods of immunotherapy were analyzed, focusing on the immunized indicators, positivity of pathogens and clinical indicators of critically ill COVID-19 patient, and the effects of immunotherapy and stem cell transplantation were evaluated.
Aged, male and people with comorbidities were the main risk factors in the development of severe and critical COVID-19. All of confirmed COVID-19 cases (n = 55) had been treated with interferon-α (IFN-α), of which 81.8% (n = 45, mild and ordinary) of the patients were recovered, 14.6% (n = 8) of the patients were converted to severe, 3.
