Structure-activity relationship study of novel evodiamine amino acid conjugates with potent anti-colorectal cancer efficacy.

Evodiamine has been a promising lead structure with broad-spectrum antitumor activity. Druggability optimization is the most challenging part of evodiamine-based lead-to-candidate campaign. Amino acids as building blocks for conjugates are widely incorporated into approved drug and drug candidates, demonstrating highly attractive druggability.

The application effect of the segmented teaching method in training medical students on clinical practice skills.

Background: The surgical clinical practice skill training is an important part of medical undergraduate education. Surgical skills are complex and difficult to master. However, the traditional teaching method has some disadvantages, for example, low student participation, weak learning atmosphere, inadequate mastery of the subject matter.

Comparative effectiveness of myocardial patches and intramyocardial injections in treating myocardial infarction with a MitoQ/hydrogel system.

In cardiac tissue engineering, myocardial surface patches and hydrogel intramyocardial injections represent the two primary hydrogel-based strategies for myocardial infarction (MI) treatment. However, the comparative effectiveness of these two treatments remains uncertain. Therefore, this study aimed to compare the effects of the two treatment modalities by designing a simple and reproducible hydrogel cross-linked with γ-PGA and 4-arm-PEG-SG.

Study on preoperative treatment of acute Type-A aortic dissection with endotracheal intubation combined with deep analgesia and sedation.

Objectives: To investigate the efficacy and safety of endotracheal intubation combined with deep analgesia and sedation in the prevention of preoperative dissection rupture in acute Standford type A aortic dissection.

Methods: This study evaluated the impact of preoperative endotracheal intubation combined with deep analgesia and sedation on acute Stanford Type-A aortic dissection. Conducted at the First Affiliated Hospital of the University of South China's cardiac intensive care unit from June 2018 to December 2021, 134 diagnosed patients participated.

[Corrigedum] miR‑185 inhibits non‑small cell lung cancer cell proliferation and invasion through targeting of SOX9 and regulation of Wnt signaling.

Subsequently to the publication of the above paper, an interested reader drew to the authors' attention that, for the Transwell invasion assay experiments with the SK‑MES‑1 cell line shown in Fig. 4A on p. 1748, the 'mimic'NC' and 'inhibitor‑NC' data panels showed overlapping sections, such that these data may have been derived from the same original source even though they were intending to show the results of different experiments.

Transthoracic Color Doppler Ultrasound-Guided Grooved Negative Pressure Drainage Tube Implantation in Pericardial Effusion After Cardiac Surgery.

Introduction: Pericardial effusion is a common complication without a standard postoperative effusion treatment after cardiac surgery. The grooved negative pressure drainage tube has many advantages as the emerging alternative for drainage of pericardial effusion, such as it changes the structure of the traditional side hole, uses the capillary function to ensure drainage smooth, etc. The purpose of this study was to assess the feasibility and effectiveness of transthoracic color Doppler ultrasound-guided grooved negative pressure drainage tube implantation in pericardial effusion after cardiac surgery.

miR‑185 inhibits non‑small cell lung cancer cell proliferation and invasion through targeting of SOX9 and regulation of Wnt signaling.

SRY-box 9 (SOX9) is an important transcription factor required for development, which has additionally been reported to be an independent prognostic indicator for the survival of patients with non‑small cell lung cancer (NSCLC). Accumulating evidence has indicated that dysregulation of microRNAs (miRNAs/miRs) may contribute to the initiation and progression of cancer. SOX9 may be regulated by a number of miRNAs in different types of cancer, including in NSCLC.
