Liquid crystal elastomer actuator with serpentine locomotion.

A snake-mimic soft actuator composed of a bilayered liquid crystal elastomer ribbon and two serrated feet is reported in this work. Under repeated on/off near-infrared light irradiation, this actuator can move forward relying on a reversible shape morphing between S-curve structure and reverse S-curve structure, which is similar to the serpentine locomotion of snakes.

Surgical Management of Plantar Melanoma: A Retrospective Study in One Center.

Cutaneous melanoma is a highly malignant skin tumor, and in China, the planta pedis is a commonly involved site. The sites of plantar melanomas are a challenge to reconstruct after wide excision. Our experience with surgical management of melanomas was based on the 4 different anatomic subunits of the planta pedis.

Surgical management of giant neurofibroma in soft tissue: a single-center retrospective analysis.

Neurofibroma, a common benign tumor in soft tissue, continues to grow, and often appears to be giant. In this study, we retrospectively analyzed the surgical treatment of 26 patients with giant neurofibromas in our clinic in the past 10 years from Jan. 2004 to Dec.

Surgical Management of Giant Scalp Neurofibroma After Ultra-Selective Embolization of Nutrient Artery.

Objectives: Neurofibroma, a common benign tumor in soft tissue, continues to grow, so it often appears to be giant. Surgical management of giant neurofibroma is a challenge due to the risk of excessive bleeding. Embolization of tumor's nutrient artery may reduce the blood loss in operation.

Percutaneous sinus angiography and three-dimensional CT imaging showing morphological and draining features of venous malformations in soft tissue.

Objective: Venous malformation (VM) is a common vascular malformation in soft tissue. Its morphological and draining features, relationship with main vein, and hemodynamics in the lesion are not completely clear till now. Above information is important for choice of treatment.

[Treatment of complicated cavernous venous malformation with retained copper wires combined with pingyangmycin injection].

Objective: To evaluate the therapeutic effect of retained copper wires combined with pingyangmycin (PYM) injection for complicated cavernous venous malformation.

Methods: The location of venous malformation was detected by physical examination and MRI. The copper wires in 0.

[Central wedge resection and asymmetric Z-plasty for minor labia reduction].

Objective: To investigate the therapeutic effect of central wedge resection and asymmetric Z-plasty for minor labia reduction.

Methods: Based on the Giraldo procedure, the incision was designed and the redudent tissue was resected quantitatively. The Z-plasty was modified to rectangle flap with deviated incision.

[Plastic treatment of Paget's disease of the scrotum and penis].

Objective: To explore the clinical features and plastic treatment of Paget's disease of the scrotum and penis.

Methods: We analyzed 11 cases of Paget's disease of the scrotum and penis treated from 1997 to 2007. Extended excision of the focus of infection was performed and the skin absence was repaired by free skin grafting, local random skin flap, and island skin flap.

[The expression and role of glucose transporter-1 in infantile hemangioma].

Objective: To investigate the expression and role of glucose transporter-1 (Glut1) in infantile hemangioma.

Methods: Fifty-two samples from infantile hemangioma, 25 in cavernous venous malformation, 9 in arteriovenous malformation, 2 in capillary malformation and 5 in normal skin samples were involved in this study. The EnVision immunohistochemical stain was used to investigate the expression of Glut1 protein in these samples.

[Allograft transplantation with compound tissue of two ears and skin of head and neck: A report of 1 case, China].

Objective: To investigate the possibility and efficacy of allograft transplantation in treating patient with huge tissue defect after radical giant malignant melanoma resection.

Methods: A male person received blood type matching was chosen as donor. Immediately after the donor's brain death, allograft was excised with the depth to the layer intervenient between periosteum and epicranial fascia in calvaria, the superficial layer of deep temporal fascia in both sides of temporal regions, close to zygomatic bones and mandibles including masseter and auricles upon in face, and cervical soft tissues including sternocleidomastoid muscles, cervical and external jugular vessels of both sides were excised simultaneously.
