A New Definition for Alar Flare Based on "Alar Flare Angle".

Background: An accurate diagnosis and an appropriate treatment are important parts of successful rhinoplasty. We proposed a new definition for alar flares to guide our clinical work.

Methods: A retrospective study was conducted on patients with alar flares from July 2017 to July 2021, and the follow-up time ranged from 12 to 27 months, mean of 16 months.

The impact of COVID-19 on plastic and reconstructive surgery in China: A single-centre retrospective study.

Background: This study aimed to investigate the volume of plastic surgery operations in a large public hospital and figure out the changes in the related factors associated with Coronavirus Disease 2019 (COVID-19) and identify the potential problems.

Methods: We created a survey and collected clinical data from 1 January 2018 to 31 December 2020. Information on procedure time, patient gender, patient age, and procedure type was collected from the database.

Clinical Application of Pre-Expanded Perforator Flaps.

Challenging large soft tissue defects are typically treated with microvascular free tissue transfer; however, success has been noted with pre-expanded perforator flaps. To report outcomes and complications from pre-expanded perforator flaps. A retrospective chart review of patients undergoing tissue reconstruction with pre-expanded perforator flaps between 2014 and 2020.

A comprehensive analysis of the correction of alar retraction in rhinoplasty: A systematic review.

Background: Alar retraction, as a type of alar deformity, seriously affects the esthetic perception of the nose in patients. Despite the rapid development of rhinoplasty in recent years, the treatment of alar retraction is still a challenge work in plastic surgery. This systematic review highlights the etiology, treatment, and prevention of alar retraction to further guide practitioners.

[Angiopoietin-like 4 modulates aldolase A expression in human melanoma cell in a PKC dependent manner].

Objective: To investigate the association between angiopoietin-like 4 (ANGPTL4) and aldolase A (ALDOA) in human melanoma cell. 


Methods: Overexpression or knockdown of ANGPTL4 was performed in WM-115 or WM-266-4 cells, respectively. The expression of ANGPTL4 and ALDOA was measured by RT-PCR and Western blot, respectively.

[Application of four-dimensional computed tomography angiography in the study of vascular structure of the deep inferior epigastric artery perforator].

Objective: To explore the vascular structure of the deep inferior epigastric artery perforator with the four-dimensional computed tomography (CT) angiography.

Methods: 10 abdominal specimens harvested from fresh cadavers were cannulated with trocar and injected with contrast medium in the deep inferior epigastric artery at different levels, including the deep inferior epigastric artery, its bifurcations, the lateral or medial large perforators. During the perfusion of the contrast medium in the flap, the flap was scanned by three-dimensional CT (four-dimensional defined as three dimensional CT plus time).

[Clinical application of intensive CT in pedicled deep inferior epigastric perforator flap design].

Objective: To explore the effect of the intensive CT on the deep inferior epigastric perforator (DIEP) flap design strategy.

Methods: From June 2007 to March 2008, 7 patients received reconstructive operation of the vertical DIEP flap, among whom there were 5 females with congenital absence of vagina and 2 males with peno-scrotal Paget's disease, aged 18-62 years old. Before the operation, the intensive CT scans were applied to all the patients in search for DIEP.
