ion 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). read more The mRNA expressions of GRP78, PERK and CHOP were also significantly decreased [GRP78 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 seable.
In addition to IFN, gamma globulin, antiserum and MSC transplantation therapy can help clear the virus and reduce inflammation. Although MSC transplantation fail to completely change the immunecompromised state of critically ill patients, it controlled the progression of inflammation in the liver and kidneys.

Lots of studies have been conducted to solve COVID-19-related problems. Therefore, we reviewed the annual progress for COVID-19-related issues including antivirals threapies, respiratory support and immunomodulatory therapies and other critical issues, including the effect of antibiotic on mitochondrial damage and its relationship with sepsis, the goal and direction of antimicrobial de-escalation, drug prophylaxis of constipation, bleeding in gastrointestinal disorders and management of critical illness in the informalization era and so on. We hope to provide reference for clinical and scientific research work of the intensivists.Earth is home not only to humans, but also to everything, including viruses. In the current globalization of coronavirus disease 2019 epidemic, the fluctuations of novel coronavirus makes epidemic prevention and control work normal, and the initiator of the accident, 2019 novel coronavirus, will coexist with human society for a long time. How we can coexist peacefully with them in this state is worth to thinking and studying.read more
