Design and Construction of Carbon-Coated Fe O /Cr O Heterostructures Nanoparticles as High-Performance Anodes for Lithium Storage.

Transition metal oxides, highly motivated anodes for lithium-ion batteries due to high theoretical capacity, typically afflict by inferior conductivity and significant volume variation. Architecting heterogeneous structures with distinctive interfacial features can effectively regulate the electronic structure to favor electrochemical properties. Herein, an engineered carbon-coated nanosized Fe O /Cr O heterostructure with multiple interfaces is synthesized by a facile sol-gel method and subsequent heat treatment.

Preparation of BiO-YSZ and YSB-YSZ Composite Powders by a Microemulsion Method and Their Performance as Electrolytes in a Solid Oxide Fuel Cell.

BiO is a promising sintering additive for YSZ that not only decreases its sintering temperature but also increases its ionic conductivity. However, BiO preferably grows into large-sized rods. Moreover, the addition of BiO induces phase instability of YSZ and the precipitation of monoclinic ZrO, which is unfavorable for the electrical property.

Fractal analysis of rat dermal tissue in the different injury states.

Scar formation and chronic ulcers can develop following a skin injury. They are the result of the over- or underproduction of collagen. It is very important to evaluate the quality and quantity of the collagen that is produced during wound healing, especially with respect to its structure, as these factors are very important to a complicated outcome.

Primary repair of broad bilateral complete cleft palate with hard palate rotation flap.

It was hard to achieve primary repair for infants with broad bilateral complete cleft palate, and usually multiple procedures are demanded, resulting in multiple injuries and scar hyperplasia, which could influence infants' long-term phonetic function. In this study, primary repair was carried out on 12 cases of 18- to 30-month-old infants who had complete cleft palate by using rotated hard palate flap with a pedicle on the edge of the fissure modified on the basis of traditional von Langenbeck palatoplasty. Eight infants were subjected to initial phonetic sound evaluation at 1 to 2 years after the operation.

Surgical treatment of hermaphroditism: experience with 25 cases.

This article is a summary of our experience with surgical treatment of 25 patients with hermaphroditism. We treated 25 patients with hermaphroditism since 1985, including 12 with male pseudohermaphroditism, 9 with female pseudohermaphroditism and 4 with true hermaphroditism. Decision on sex reassignment for these patients was made according to their genetic sex, gonad sex, social sex, psychologic sex, and the request of the patients and their relatives.

[Immediate reconstruction of tissue defects on eyelid caused by tumor excision].

Objective: To introduce the methods for immediate reconstruction of tissue defects on eyelid caused by tumor excision.

Methods: Single or combined local skin flaps were used to repair tissue defects on eyelids after tumor excision.

Results: Since 1994, 216 patients (224 sides) were treated.

The island myocutaneous flap reconstruction in electrical burn injuries of severely traumatized cervical region.

Trauma patients with high-energy injuries often present with severe tissue damage that extends beyond the immediate zone of injury and require recruitment of vascularized and massive tissues. The objective of this study was to evaluate the utility of the island myocutaneous flap for the reconstruction of the electrical burn injuries on the cervical region. We conducted a retrospective chart review on all trauma patients treated by the Department of Plastic Surgery at Changhai Hospital, Second Military Medical University who required a large amount of vascularized tissue for the reconstruction of the electrical burn injuries on the cervical region from July 1994 to June 2006.

[Application of flap in repair of heel skin and soft tissue defect].

Objective: To introduce the experience and comprehend of application of many kinds of skin flaps in repair of heel skin and soft tissue defect.

Methods: From August 1993 to April 2007, 242 cases of skin and soft tissue defect on heel were treated. There were 157 males and 85 females aged 27-76 years.

Treatment for long-term poorly closed incisions after hepatobiliary surgery.

Background: Effective measures are lacking to treat long-term poorly closed incisions after hepatobiliary surgery, including chronic sinus tract and keloid. This study aimed to introduce the treatment experiences with the abdominal wall and costal margin complications after hepatobiliary surgery, and to investigate the method for prevention of this kind of complication.

Methods: We retrospectively studied 26 patients with complications of abdominal wall and costal margin after hepatobiliary surgery, who had been admitted to our hospital since 1998.

[Local flap for reconstruction of nasal tip defect: functional and aesthetic evaluations].

Objective: To introduce the experience of reconstruction of nasal tip defect, which could obtain good functional and aesthetic results.

Methods: Based on the aesthetic subunit principle, according to the size, shape, depth of nasal tip defect, and the conditions of surrounding skin, homologous local flap (include: frontonasal flap, bilobed flap, nasolabial flap, reforming rhomboid flap and forehead flap, etc.) was designed to cover the defect wound.

[Discoidin domain receptors (DDRs) expression in pathological scar fibroblast formation].

Objective: To explore the role of discoidin domain receptors (DDRs) in the formation of the keloid.

Methods: The real-time quantitative PCR was used to compare the DDRs expression in the keloids and normal fibroblasts.

Results: The level of DDR1 expression was significantly higher in keloid than in normal fibroblast (20.

[Expression of alpha-melanocyte-stimulating hormone in human split-thickness skin graft].

Objective: To investigate the expression of alpha-melanocyte-stimulating hormone (alpha-MSH) in human split-thickness skin autograft and the role of alpha-MSH in hyperpigmented process of the grafted skin.

Methods: Immunohistochemical technique was used to detect the expression and distribution of alpha-MSH in the split-thickness grafted skin and normal skin separately.

Results: The expression of alpha-MSH in most of the split-thickness grafted skin was much stronger than the control skin.

[The effects of chitosan on different-derived fibroblasts].

Objective: To investigate the effects of chitosan on the biological activities of the fibroblasts derived from different tissues.

Methods: The biological activities of the fibroblasts derived from different tissues were evaluated with a MTT method for fibroblast proliferation, photic and electronic microscope for morphologic and subcellular structure, 3H-proline uptake method for collagen secretion and ELISA box for the secretion of TGF-beta 1, FGF-AB, and IL-8.

Results: This study showed that the chitosan inhabited the proliferation of the fibroblasts and the secretion of the TGF-beta 1, FGF-AB and collagen of the fibroblasts with a dose-depended manner in the normal skin, hypertrophic scar and keloid groups, but it stimulated the IL-8.
