CUX1 attenuates the apoptosis of renal tubular epithelial cells induced by contrast media through activating the PI3K/AKT signaling pathway.

Objective: Contrast media (CM) is a commonly applied drug in medical examination and surgery. However, contrast-induced acute kidney injury (CIAKI) poses a severe threat to human life and health. Notably, the CUT-like homeobox 1 (CUX1) gene shows protective effects in a variety of cells.

Atorvastatin reduces contrast media-induced pyroptosis of renal tubular epithelial cells by inhibiting the TLR4/MyD88/NF-κB signaling pathway.

Background: Contrast-induced acute kidney injury (CI-AKI) is the third most common cause of hospital-acquired renal failure. However, there is no effective treatment of CI-AKI, and its mechanism is unknown. Interestingly, atorvastatin has been reported to be effective in renal injury.

Friend or Foe? Flipped Classroom for Undergraduate Electrocardiogram Learning: a Randomized Controlled Study.

Background: Interpreting an electrocardiogram (ECG) is not only one of the most important parts of clinical diagnostics but also one of the most difficult topics to teach and learn. In order to enable medical students to master ECG interpretation skills in a limited teaching period, the flipped teaching method has been recommended by previous research to improve teaching effect on undergraduate ECG learning.

Methods: A randomized controlled trial for ECG learning was conducted, involving 181 junior-year medical undergraduates using a flipped classroom as an experimental intervention, compared with Lecture-Based Learning (LBL) as a control group.

Effect of Mini-Tyrosyl-tRNA Synthetase/Mini-Tryptophanyl-tRNA Synthetase on Angiogenesis in Rhesus Monkeys after Acute Myocardial Infarction.

Aims: The purpose of this study was to clarify the effect of mini-tyrosyl-tRNA synthetase/mini-tryptophanyl-tRNA synthetase (mini-TyrRS/mini-TrpRS) in ischemic angiogenesis in rhesus monkeys with acute myocardial infarction (AMI).

Methods: A 27-gauge needle was incorporated percutaneously into the left ventricular myocardium of rhesus monkeys with AMI. All monkeys were randomized to receive adenoviral vector mini-TyrRS/mini-TrpRS, which was administered as five injections into the infarcted myocardium, or saline or ad-null (control groups).

Preliminary investigation into application of problem-based learning in the practical teaching of diagnostics.

Background: Problem-based learning (PBL) is a pedagogical approach based on problems. Specifically, it is a student-centered, problem-oriented teaching method that is conducted through group discussions. The aim of our study is to explore the effects of PBL in diagnostic teaching for Chinese medical students.

New ideas for teaching electrocardiogram interpretation and improving classroom teaching content.

Background: Interpreting an electrocardiogram (ECG) is not only one of the most important parts of diagnostics but also one of the most difficult areas to teach. Owing to the abstract nature of the basic theoretical knowledge of the ECG, its scattered characteristics, and tedious and difficult-to-remember subject matter, teaching how to interpret ECGs is as difficult for teachers to teach as it is for students to learn. In order to enable medical students to master basic knowledge of ECG interpretation skills in a limited teaching time, we modified the content used for traditional ECG teaching and now propose a new ECG teaching method called the "graphics-sequence memory method.

[Continuous blood purification therapy on 16 patients with diabetic ketoacidosis and acute kidney injury].

Objective: To determine the effectiveness of Continuous blood purification (CBP) therapy on diabetic ketoacidosis (DKA) and acute kidney injury (AKI) in diabetic nephropathy (DN) patients.

Methods: Sixteen DN patients who developed severe DKA and AKI between 2008 and 2011 in the West China Hospital were recruited. All of the recruited patients presented with severe metabolic acidosis, electrolyte disturbance and dehydration.
