Antibacterial tellurium-containing polycarbonate drug carriers to eliminate intratumor bacteria for synergetic chemotherapy against colorectal cancer.

Intratumor microbes have attracted great attention in cancer research due to its influence on the tumorigenesis, progression and metastasis of cancer. However, the therapeutic strategies targeting intratumoral microbes are still in their infancy. Specific microorganisms, such as Fusobacterium nucleatum (F.

Correlation of Krebs von den Lungen-6 and fibronectin with pulmonary fibrosis in coronavirus disease 2019.

Objective: Coronavirus Disease 2019 (COVID-19) caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still spreading worldwide, which may progress to pulmonary fibrosis (PF), leading to the worsen outcome. As the markers of lung injury, the correlation of Krebs von den Lungen-6 (KL-6) and fibronectin (Fn) with pulmonary fibrosis in COVID-19 was still unclear.

Methods: 113 patients diagnosed as COVID-19 were enrolled in this retrospective study, and divided into three categories as mild, moderate and severe cases.

Evaluation of serum hepatic enzyme activities in different COVID-19 phenotypes.

Coronavirus disease 2019 (COVID-19) is a newly emerging infectious disease. Our understanding of the clinical characteristics of liver damage and the relationship with disease severity in COVID-19 is still limited. To investigate the serum hepatic enzyme activities in different phenotypes of COVID-19 patients, evaluate their relationship with the illness severity and analyze the correlation of glycyrrhizin treatment and abnormal liver enzyme activities, one hundred and forty-seven patients with COVID-19 were enrolled in a retrospective study that investigated hepatic dysfunction.

Epidermal growth factor alleviates cerebral ischemia-induced brain injury by regulating expression of neutrophil gelatinase-associated lipocalin.

Neutrophil gelatinase-associated lipocalin (NGAL) may be a biomarker candidate for brain injury and a novel therapeutic target in ischemic stroke. Epidermal growth factor (EGF) has protective effects on ischemic injury via activating EGF receptor (EGFR). Whether the protection mechanism of activating EGF-EGFR axis against brain injury is involved in regulating NGAL is still unknown.

Procalcitonin is a good tool to guide duration of antibiotic therapy in patients with severe acute pancreatitis. A randomized prospective single-center controlled trial.

Objective: To investigate the clinical usefulness of procalcitonin (PCT) for guiding duration of antibiotic therapy in patients with severe acute pancreatitis (SAP).

Methods: A total of 71 patients with confirmed severe acute pancreatitis from March 2009 to September 2011 in the Department of Critical Care Medicine of Huizhou Municipal Central Hospital, Guangdong, China were enrolled in this study. Procalcitonin was measured daily by a semi-quantitative immunoassay in the study group.
