Ultrasound-Guided "Cross Injection" Technique for Mouth Corner Lift with Botulinum Toxin Type A.

Background: Drooping mouth corner may lead to a sad, tired or aging appearance, which could be corrected by injection of botulinum neurotoxin. In the article, we describe a novel "cross injection" technique for mouth corner lift with botulinum neurotoxin injection guided by ultrasound.

Methods: Patients with drooping mouth corner were treated with botulinum neurotoxin injection using ultrasound-guided "cross injection" technique.

A prospective and randomized study comparing ultrasound-guided real time injection to conventional blind injection of botulinum neurotoxin for glabellar wrinkles.

Background: Botulinum neurotoxin injections are the most frequently performed cosmetic procedures, but conventional blind injection for glabellar wrinkles remains to have some limitations.

Aims: We intend to directly inject botulinum neurotoxin into the glabella complex guided by real time ultrasound. We aim to propose a more efficient and safer botulinum neurotoxin injection strategy for glabellar wrinkles.

Bibliometric research on analysis of links between periodontitis and cardiovascular diseases.

Background: Periodontitis (PD) and cardiovascular diseases (CVD) rank among the most prevalent pathologies worldwide, and their correlation has been a subject of prolonged investigation. Numerous studies suggest shared etiological factors; however, a definitive causal connection remains unestablished. The objective of this study was to employ bibliometric and visual analyses in order to comprehensively examine the overarching characteristics, focal areas of research, and prospective trends pertaining to the PD-CVD relationship.

Scientometric Research on Trend Analysis of Nano-Based Sustained Drug Release Systems for Wound Healing.

Nanomaterials, such as the nanoparticle (NP), nanomicelle, nanoscaffold, and nano-hydrogel, have been researched as nanocarriers for drug delivery more and more recently. Nano-based drug sustained release systems (NDSRSs) have been used in many medical fields, especially wound healing. However, as we know, no scientometric analysis has been seen on applying NDSRSs in wound healing, which could be of great importance to the relevant researchers.

[Application of local skin flaps in adjustment of reconstructed nasal alars at second stage].

Objective: To investigate the effectiveness of local skin flaps such as V-Y advancement flap (V-Y plasty) and transposition flap (Z plasty) in the adjustment of reconstructed nasal alars at second stage.

Methods: Between June 2012 and January 2017, 14 cases of reconstructed nasal alars by nasolabial flap or expanded forehead flap were recruited. There were 9 males and 5 females with an average age of 34.

Enhanced Repairing of Critical-Sized Calvarial Bone Defects by Mussel-Inspired Calcium Phosphate Cement.

The goal of this study is to investigate the biological response of mussel-inspired calcium phosphate cement (CPC) in vivo. Polydopamine (PDA), which is analogous to that of mussel adhesive proteins, was added in CPC. PDA-CPC was implanted into the femur, muscle, and critical-sized calvarial bone defects of rabbits.

[EFFECTIVENESS OF DEEP INFERIOR EPIGASTRIC ARTERY PERFORATOR FLAP FOR REPAIR OF PERINEAL AND PERIANAL CICATRICIAL CONTRACTURE].

Objective: To discuss the effectiveness of deep inferior epigastric artery perforator flap to repair perineal and perianal cicatricial contracture.

Methods: Between March 2007 and December 2013, 23 patients with perineal and perianal cicatricial contracture were treated with deep inferior epigastric artery perforator flap. There were 15 males and 8 females, aged from 21 to 62 years (mean, 42 years).

Effect of polydopamine on the biomimetic mineralization of mussel-inspired calcium phosphate cement in vitro.

Inspired by the excellent adhesive property of mussel adhesive protein, we added polydopamine (PDA) to calcium phosphate cement (PDA-CPC) to enhance its compressive strength previously. The mineralization and mechanism on PDA-CPC were investigated by soaking it in simulated body fluid in this study. The results indicated that PDA promoted the conversion of dicalcium phosphate dihydrate and α-tricalcium phosphate to hydroxyapatite (HA) in the early stage but inhibited this conversion subsequently.

New horizontal v-shaped osteotomy for correction of protrusion of the zygoma and the zygomatic arch in East Asians: indication and results.

Protrusion of the zygoma is commonly considered undesirable and unattractive among East-Asians, and many try to achieve a harmonious oval midface by having various cosmetic operations. However, effective contouring for a severe protruding zygoma has rarely been reported .The objectives of this study therefore were to investigate the feasibility and effectiveness of a horizontal V-shaped ostectomy for correction of protrusion of the zygoma and zygomatic arch, and to discuss its indications.

High conversion self-curing sealer based on a novel injectable polyurethane system for root canal filling.

Low monomer-polymer conversion is the key factor leading to cytotoxicity for resin-containing restorative materials. This paper provides a new root canal filling system based on self-curing injectable polyurethane which can achieve high conversion in a short time. Traced FTIR spectra show more than 90% NCO group participated in the curing reaction after 4h, and only about 5% remained after 24h.

Preliminary evaluation of a novel strong/osteoinductive calcium phosphate cement.

We developed a novel calcium phosphate cement (CPC) by combining the silk fibroin and osteogenic supplements (β-glycerophosphate, ascorbic acid, and dexamethasone) with α-tricalcium phosphate cement. Mesenchymal stem cells (MSCs) were cultured on the novel CPC scaffold. Results showed that the novel CPC scaffold was biocompatible and favorable for the adhesion, spreading, and proliferation of MSCs.
