Development and validation of a nomogram to predict risk of septic cardiomyopathy in the intensive care unit.

The aim of this study was to develop a simple but effective nomogram to predict risk of septic cardiomyopathy (SCM) in the intensive care unit (ICU). We analyzed data from patients who were first admitted to the ICU for sepsis between 2008 and 2019 in the MIMIC-IV database, with no history of heart disease, and divided them into a training cohort and an internal validation cohort at a 7:3 ratio. SCM is defined as sepsis diagnosed in the absence of other cardiac diseases, with echocardiographic evidence of left (or right) ventricular systolic or diastolic dysfunction and a left ventricular ejection fraction (LVEF) of less than 50%.

MicroRNA-21: A Critical Pathogenic Factor of Diabetic Nephropathy.

Diabetic nephropathy (DN), one of the most common and intractable microvascular complications of diabetes, is the main cause of terminal renal disease globally. MicroRNA-21 (miR-21) is a kind of miRNA early identified in human circulation and tissues. Mounting studies have demonstrated that miR-21 plays an important role in the development and progression of DN.

[Setup a model for study the interfere between chemokine and immunocyte].

Objective: To investigated the effect of chemoattractant of rhTNF-alpha on TB-LCL. Set up a model for study the interaction between cytokine and B cells.

Method: PTC were transfected with Epstein Barr virus, to get tonsil B lymphoblastic cell line(TB-LCL).
