Deptor protects against myocardial ischemia-reperfusion injury by regulating the mTOR signaling and autophagy.

Deptor knockout mice were constructed by crossing Deptor Floxp3 mice with myh6 Cre mice, establishing a myocardial ischemia-reperfusion (I/R) model. Deptor knockout mice exhibited significantly increased myocardial infarction size and increased myocardial apoptosis in vivo. ELISA analysis indicated that the expression of CK-MB, LDH, and CtnT/I was significantly higher in the Deptor knockout mice.

False lumen patency status and outcomes after endovascular repair of uncomplicated chronic type B dissection.

Background: Thoracic endovascular aortic repair (TEVAR) remains a controversial treatment for uncomplicated chronic type B aortic dissection (cTBAD). This study was performed to investigate the postoperative outcomes of TEVAR, such as survival and reintervention, and the risk factors for prognoses.

Methods: In total, 41 patients with uncomplicated cTBAD who underwent TEVAR from 2014 to 2021 were reviewed.

Basic investigation into the present burn care system in China: burn units, doctors, nurses, beds and special treatment equipment.

Objective: The aim of the study was to survey the current burn units in China to understand the burn care system in the country and supply basic data for the National Burn Repository of China (NBRC) and further research.

Method: A questionnaire was developed and sent to burn unit directors in China via e-mail, which was followed up with reminder text messages to obtain information for the study.

Results: Of the 405 hospitals from the 31 provinces in mainland China that responded to the questionnaire, 63.

Successful Treatment of a Patient With Complicated Diabetic Foot Wound: A Case Report.

Foot ulceration is one of the most serious complications of diabetes mellitus and may lead to amputation of the lower extremity. Timely prophylaxis and treatment of diabetic foot ulceration are important to maintain a good quality of life. This article reports a complicated diabetic patient with severe limb-threatening necrotizing infection.

In vitro evaluation of Panax notoginseng Rg1 released from collagen/chitosan-gelatin microsphere scaffolds for angiogenesis.

Background: The emergence of skin substitutes provides a new approach for the treatment of wound repair and healing. The consistent and steady release of angiogenic factors is an important factor in the promotion of angiogenesis in skin substitutes, which usually lack, yet need, a vascular network.

Methods: In this study, ginsenoside Rg1, a natural compound isolated from Panax notoginseng (PNS), was incorporated into a collagen/chitosan-gelatin microsphere (CC-GMS) scaffold.

The roles of knitted mesh-reinforced collagen-chitosan hybrid scaffold in the one-step repair of full-thickness skin defects in rats.

Full-thickness skin defects represent a significant and urgent clinical problem. Dermal substitutes serving as a regenerative template to induce dermal reconstruction provide a promising method to treat serious skin defects. Although collagen-chitosan dermal scaffolds display good biocompatibility and a suitable porous structure for angiogenesis and tissue regeneration, their poor mechanical properties compromise their application.

[Advances in research of the strategies for promoting angiogenesis in tissue engineering].

Rapid angiogenesis is one of the major issues in the field of tissue engineering, and it is an urgent problem to be solved. The process and related mechanism of angiogenesis have been deeply researched. Meanwhile, various methods or strategies for promoting angiogenesis, involving the application of stem cells and growth factors, and construction and modification of biomaterial scaffolds, have also been reported.
