Safety and efficacy of the amino acid crosslinked hyaluronic acid in the treatment of temple hollowing.

Background: Loss of volume in the temples is an early sign of aging and often gives the impression of a gaunt and emaciated appearance.

Objective: The authors conduct a clinical study to investigate the safety and effectiveness of the amino acid crosslinked hyaluronic acid (ACHA) for the treatment of temple hollowing.

Methods: 75 subjects with Temple Hollowing Scale (THS) from 2 to 4 were enrolled and assigned according to the ratio of 2 (ACHA group, n = 50): 1 (no treatment control group, n = 25).

Botulinum Toxin Type A Alleviates Androgenetic Alopecia by Inhibiting Apoptosis of Dermal Papilla Cells via Targeting circ_0135062/miR-506-3p/Bax Axis.

Botulinum toxin type A (BTXA) has the potential to treat androgenetic alopecia (AGA); however, its impact on the apoptosis of dermal papillary cells (DPCs) is not yet fully understood. Noncoding RNAs play a crucial role in AGA. In this study, we investigated the potential mechanism by which BTXA alleviates apoptosis induced by dihydrotestosterone (DHT) in DPCs.

Treatment of Chin Retrusion With Botulinum Toxin Plus Hyaluronic Acid Filler in Comparison With Hyaluronic Acid Filler Alone: A Randomized, Evaluator-Blinded, Controlled Study.

Background: Hyaluronic acid (HA) has already been widely administered for chin augmentation. Patients with chin retrusion frequently present with increased chin hypertonia. Monotherapy with HA falls short in addressing the multifaceted cosmetic concerns associated with chin retrusion.

CircAGK regulates high dihydrotestosterone-induced apoptosis in DPCs through the miR-3180-5p/BAX axis.

The incidence of androgen alopecia (AGA), also known as seborrheic alopecia, has surged in recent years, and onset is occurring at younger ages. Dermal papilla cells (DPCs) are key to maintaining hair cycling, and apoptosis-driven processes in DPCs are closely related to hair follicle regeneration. Circular RNAs (circRNAs) are widely present in the human body and are closely related to the occurrence and development of many diseases.

Application of lncRNA-miRNA-mRNA ceRNA network analysis in the treatment of androgenic alopecia.

Background: Long noncoding RNAs (lncRNAs) can be used as competitive endogenous RNAs (ceRNAs) to bind to microRNAs (miRNAs) to regulate gene expression. Previous studies have demonstrated that ceRNAs play an important role in the development of tumors. However, it is not clear whether the lncRNA-miRNA-mRNA ceRNA network plays a role in androgenic alopecia (AGA).

Graphene oxide accelerates diabetic wound repair by inhibiting apoptosis of Ad-MSCs via Linc00324/miR-7977/STK4 pathway.

Many studies have shown that graphene oxide (GO) promotes proliferation and differentiation of a variety of stem cells. However, its effect on adipose-derived mesenchymal stem cell (Ad-MSCs) apoptosis is still unclear. Apoptosis is a significant factor affecting stem cell-based treatment of diabetic wounds.

Three-Dimensional Rapid Printing-Assisted Individualized Total Nasal Reconstruction Based on a Database of Normal External Noses.

Background: The nose is an unpaired facial structure. Applying three-dimensional rapid printing to total nose reconstruction is difficult because no paired structure is available for reference. In this study, three-dimensional laser scanning was used to create a database of normal external noses of Han Chinese individuals in East China to assist in total nose reconstruction.

Correction of breast asymmetry by autologous fat grafting with the aid of 3D laser-scanning technology.

Background: Currently, the lack of clinically accurate measurement and evaluation methods for breast asymmetry has considerably limited the use of autologous fat grafting in the correction of breast asymmetry.

Objective: This study calculated the volume difference in the bilateral breasts by three-dimensional (3D) laser scanning technology, established a bridge between digitalization and surgery to guide the correction of breast asymmetry by autologous fat grafting, and evaluated the surgical effect.

Methods: In the experimental group (3D group), the measurement range was defined by standardized methods, the algorithm to calculate the volume difference in the bilateral breasts was determined by the established software instructions, and the volume of intraoperative autologous fat grafting was guided by personalized data.

Exosomal microRNA⁃93⁃3p secreted by bone marrow mesenchymal stem cells downregulates apoptotic peptidase activating factor 1 to promote wound healing.

Wounds are soft tissue injuries, which are difficult to heal and can easily lead to other skin diseases. Bone marrow mesenchymal stem cells (BMSCs) and the secreted exosomes play a key role in skin wound healing. This study aims to clarify the effects and mechanisms of exosomes derived from BMSCs in wound healing.
