We proposed that the pharynx, as a common organ of the respiratory and digestive tracts, may be a respiratory and digestive tract cross cryptic transmission pathway for 2019-nCoV infection from the nasal cavities to the pharynx and lung, then to nasal cavities by aerosol (respiratory route) to the pharynx and the gastrointestinal tract, then to the oral cavity by feces (fecal-oral route) and to pharynx, lungs, or gastrointestinal tract.

To investigate the clinical value of changes in the subtypes of peripheral blood lymphocytes and levels of inflammatory cytokines in patients with COVID-19, the total numbers of lymphocytes and CD4+ lymphocytes and the ratio of CD4+/CD8+ lymphocytes were calculated and observed in different groups of patients with COVID-19. The results show that the lymphocytopenia in patients with COVID-19 was mainly manifested by decreases in the CD4+ T lymphocyte number and the CD4+/CD8+ ratio. The decreased number of CD4+ T lymphocytes and the elevated levels of TNF-α and IL-6 were correlated with the severity of COVID-19 disease.

In order to discover novel hypoxia-inducible factor 1 (HIF-1) inhibitors for the cancer metastasis treatment, 68 new aryl carboxamide compounds were synthesized and evaluated for their inhibitory effect by dual luciferase-reporter assay. Based on five rounds of investigation on structure-activity relationships step by step, compound was discovered as the most active inhibitor (IC = 0.32 μM) with no obvious cytotoxicity (CC > 50 μM).

A novel diagnostic scheme that includes pancreatic β‑cell dysfunction analysis for the diagnosis of traumatic multiple organ dysfunction syndrome (MODS) was investigated to assist in the early diagnosis and detection of MODS. Early intervention and treatment of MODS has been associated with a reduced mortality rate. A total of 2,876 trauma patients (including patients post‑major surgery) were admitted to the intensive care unit of the authors' hospital between December 2010 and December 2015 and enrolled in the present study.

Background: Insulin, as an anti-inflammatory drug, could not be freely used in patients who experienced trauma according to the degree of inflammation, because of the side effect of hypoglycemia. In vivo experimental evidence is lacking concerning whether the effect is dosage dependent and whether it relies on controlling hyperglycemia.

Methods: By adjusting the dosage ratio of glucose and insulin, different dosages of insulin were used to treat severely scalded MODS rats to achieve uncontrolled or controlled hyperglycemia.

Background: Inflammation response and oxidative stress promote the occurrence and development of multiple-organ dysfunction syndrome (MODS).

Methods: Eighty MODS rats with third-degree burns were divided randomly into 4 groups: insulin, ethyl pyruvate (EP), insulin combined with EP, and control. Blood levels of glucose, alanine aminotransferase (ALT), creatine (CRE), creatine kinase (CK), tumor necrosis factor α (TNF-α), high-mobility group box 1 (HMGB-1), malondialdehyde (MDA), and total antioxidant capacity (TAC) before as well as 1, 3, 5, and 7 days after burns were measured.

Intestinal barrier damage after scald and burns, other trauma or major operations result in severe intestinal infections that cause serious consequences. Therefore, it is important to develop methods to protect intestinal barrier after severe burns. This study used rats that had full-thickness burn of approximately 30% of the total body surface area to investigate the effect and mechanism of glucose-insulin-potassium (GIK) and provide experimental evidence for application of GIK in protecting the intestine after burns or other trauma and major surgeries.

Objective: To evaluate the influence of glucose-insulin-potassium treatment (GIK) on the levels of inflammatory cytokines in the scalded rats with MODS.

Methods: One hundred and twenty Sprague Dawley rats were inflicted with 30% TBSA full-thickness scalding, and MODS model was reproduced with intraperitoneal injection of endotoxin following burn injury. Then the rats were randomly divided into GIK, glucose (G) and control (C) groups, with 40 rats in each group.
