Use of High-Resolution Ultrasound (HRU) in the Assessment of Deep Injections of CHAP-Hyaluronic Acid (CHAP-HA) Fillers for Midface Lift

High-resolution ultrasound (HRU) imaging is a useful tool to study hyaluronic acid (HA) filler injection in the face. It is noninvasive, quick, well-tolerated, and can provide in vivo and dynamic information. The formations of pools or pearls in HA fillers could be observed real time during injection. The plane of injection could be determined accurately, and there were no specimen manipulation artifacts. It was observed that HA gel fillers with differing production technologies showed distinct spread and distribution patterns in the periocular tissues on HRU examination. The authors used HRU to assess deep injections of CHAP-Hyaluronic Acid (CHAP-HA) fillers for midface lift. 10 patients who underwent bilateral midface deep injections using CHAP-HA filler were examined with HRU before and immediately after treatment, and in 2 weeks and one month later. The CHAP-HA appeared as hypoechoic densities within the preperiosteal plane in HRU. CHAP-HA adopted variable morphology within the tissue depending on individual tissue densities and the compliance of the tissues in the plane of injection. CHAP-HA was unidentifiable with surrounding tissue after one month in 13 of the 20 injection sites. HRU allows in vivo study of CHAP-HA injection behavior and could be a tool for further studies of HA-tissue reactions.

Relationship between Serum Hyaluronic Acid Level and Patient Prognosis in Hepatocellular Carcinoma Patients Who Underwent Hepatectomy

We examined the relationship between hyaluronic acid (HA) and tumor-related factors after hepatectomy in 158 patients with hepatocellular carcinoma (HCC) who underwent hepatectomy. We examined serum HA levels before hepatectomy by evaluating data for clinicopathological parameters, surgical records, postoperative complications and survival. The mean HA level was 190 ± 202 ng/ml. Patients were divided into 3 groups: group A had serum HA levels less than 50 ng/ml (normal range), group B had levels between 50 and 190 ng/ml, and group C had levels over 190 ng/ml. Group C had a higher rate of poor liver function compared to others. Multiple tumors were significantly more frequent in groups B and C compared to A. The grade of fibrosis and the inflammatory responses were positively correlated with the serum HA level. Postoperative long-term ascites was significantly more frequent in group C compared to others. Although the recurrence rate and the relapse-free period were not significantly related to the serum HA level, the serum HA level was significantly associated with overall survival after hepatectomy (p 0.05). Cox’s multivariate analysis did not show a significant relationship between HA level and survival. Serum HA reflects progression and survival in HCC patients.

A Face Serum Containing Palmitoyl Tripeptide-38, Hydrolyzed Hyaluronic Acid, Bakuchiol and a Polyherbal and Vitamin Blend Improves Skin Quality

A face serum composed of a combination of biologically active compounds was evaluated for safety and efficacy in vitro, in a repeat insult patch test and in a human clinical efficacy trial. The serum inhibited tyrosinase activity modestly, decreased collagenase activity and exhibited notable free radical scavenging activity in vitro. It is gentle to the skin, as the serum did not irritate the skin or produce symptoms of allergic contact dermatitis in the 55 healthy adults that participated in the repeat insult patch test. In the efficacy trial, daily application of the face serum for 30 days significantly increased skin hydration, with all 35 volunteers experiencing improvement. Substantial improvements in skin elasticity, roughness (fine lines and wrinkles), and brightness also occurred during the trial. Dermatological examination also revealed a trend for reduced comedone count with use of the serum. Self-assessment responses revealed that all volunteers experienced improvements in multiple skin quality parameters and that participant perceptions are consistent with the results of the instrumental analyses. These findings indicated that the measured improvements in skin quality are not only statistically significant but are also clinically relevant as they were great enough for users of the face serum to feel and recognize.

CHAP-Hyaluronic Acid (CHAP-HA) Filler as an Optimal Candidate for Forehead Filler Augmentation Using a 3-Point Injection Technique

Minimally invasive forehead augmentation is becoming increasingly popular in Asia. However, treatment of the glabella is associated with injection-related complications. The safety of injections can be increased through a thorough understanding of the anatomy and precise injection planes. The authors propose a 3-point injection technique for forehead augmentation in Asian patients that uses CHAP-hyaluronic acid (CHAP-HA) filler. The longevity of the filler was assessed using high-resolution ultrasound (HRU) imaging. Fifteen patients were examined using HRU before and immediately after treatment and at 1 month, 3 months, 6 months, and 12 months. As evident in HRU imaging, CHAP-HA remained visible within surrounding tissue for 6.4 ± 3.7 months. The mean Global Aesthetic Improvement Scale rating was 2.4 ± 0.5 immediately after treatment, 2.8 ± 0.3 at 1 month, 2.7 ± 0.5 at 3 months, 2.1 ± 0.6 at 6 months, and 1.5 ± 0.6 at 12 months. Minimal side effects were reported. The authors demonstrated that CHAP-HA filler may be an optimal candidate for forehead filler augmentation using a 3-point injection technique.

Effect of the hyaluronic acid-poloxamer hydrogel on skin-wound healing: in vitro and in vivo studies

Background: Recent research into skin injury and wound healing has focused mainly on post‐trauma hemostasis, infection prevention, dermal regeneration and angiogenesis. However, less attention has been paid to air permeability and moisture loss prevention which also play important roles in injury healing. Methods: In the present work, we prepared a hyaluronic acid‐poloxamer (HA‐POL) hydrogel and tested the therapeutic effect of the hydrogel on skin‐wound healing. Results: The HA‐POL hydrogel transformed from sol to gel at 30°C, close to body temperature, and had stable moisturizing properties. HA‐POL hydrogel promoted skin‐wound healing and increased protein accumulation in the wound area. HA‐POL hydrogel allowed greater air permeability than Band‐aid, a typical wound covering. Results from transwell assays showed that the HA‐POL hydrogel effectively isolated skin‐wounds from bacterial invasion. Conclusion: This work demonstrates the advantages of using HA‐POL gel materials in the treatment of cutaneous wounds.

A Guide to Cheek Augmentation: Single-Point Deep Injection of Hyaluronic Acid Filler at Midface in Close Proximity to Medial Suborbicularis Oculi Fat (SOOF) Area

Loss of volume in midface can result in an aged, wasted appearance. Osseous and fat atrophy with aging may further contribute to the loss of soft tissue support and midface ptosis. In the aging of periorbital area and midface, fat atrophy occurs mostly in the suborbicularis oculi fat (SOOF) area. The authors proposed that injection of hyaluronic acid (HA) filler to support the SOOF area could counteract the aging sign due to fat atrophy, restore volume loss and achieve a more youthful appearance. The authors described the treatment of 10 female patients who received CHAP®-particle hyaluronic acid (CHAP®-HA) injections for cheek augmentation, using single-point deep injection technique at midface in close proximity to SOOF area. Such approach provides satisfactory cheek augmentation results without significant complications. The authors discussed a rationale for their choice of dermal filler and provided an injection technique for restoring volume in the midface region with CHAP®-HA. Such technique is relatively quick to perform, have little down time, and result in a high rate of patient satisfaction.

流体剪切力下CD44-HA介导的MDA-MB-231细胞及HL60细胞的滚动黏附

目的探究胞外基质中的透明质酸(hyaluronic acid,HA)如何调控血流中CD44+肿瘤细胞的黏附滚动行为。方法采用平行平板流动腔装置,观察记录流场中MDA-MB-231细胞及HL60细胞在固定HA上的运动,提取细胞滚动黏附特征参数。结果MDA-MB-231细胞在HA底板上的黏附受到HA浓度的正向调控,但不受HA分子量影响;与物理吸附相比,生物素-亲和素固定的HA可显著提高细胞的黏附比率。在30~50 mPa剪切力范围内,剪切力的增加加快了细胞的滚动速度,降低了细胞的黏附比率,但对细胞的栓缚时间影响不大。同样流场中,与MDAMB-231细胞比较,CD44表达水平较低的HL60细胞在HA底板上的栓缚时间短、滚动速度快、黏附比率低(<1.5%)。结论流体剪切力可能通过调节CD44-HA的结合速率而非解离速率来调控MDA-MB-231细胞的滚动速度;CD44-HA相互作用参与HL60细胞的初始黏附,但不起主要作用。研究结果为抗肿瘤药物的开发提供参考。
