Psoriasis is a chronic skin disease characterized by abnormal proliferation and inflammation of epidermal keratinocytes. Fibroblast growth factor 12 (FGF12) is implicated in the regulation of diverse cellular signals; however, its precise mechanism in psoriasis requires further investigation. In this study, high expression of FGF12 is observed in the epidermis of skin lesion in psoriasis patients and imiquimod (IMQ)-induced psoriasis like-dermatitis.

Objectives: Diabetes mellitus is associated with refractory wound healing, yet current therapies are insufficient to accelerate the process of healing. Recent studies have indicated chemically modified mRNA (modRNA) as a promising therapeutic intervention. The present study aimed to explore the efficacy of small skin engineered to express modified mRNAs encoding the stromal cell-derived factor-1α (SDF-1α) facilitating wound healing in a full-thickness skin defect rat model.

Systemic sclerosis is a complex process of pathogenesis, and the contributions of inherited genes, infections, and chemicals remain largely unknown. In this study, we showed that p90 ribosomal S6 protein kinase 2 (RSK2) was selectively upregulated in fibrotic skin and fibroblasts treated with the profibrotic cytokine TGF-β. Moreover, knockout of Rsk2 specifically in skin fibroblasts or pharmacological inhibition of RSK2 attenuated skin fibrosis in a mouse model.

Objectives: Ultraviolet light B (UVB) irradiation can induce skin injury and result in keratinocytes proliferation inhibition. However, the molecular understanding of the repair during UVB-induced cell proliferation inhibition remains poorly understood. The purpose of this study was to explore the role and potential mechanism of FGF10 in promoting keratinocytes cell cycle and proliferation after UVB injury.

Osteoarthritis (OA) is a chronic degenerative disease wherein the articular cartilage exhibits inflammation and degradation. Scutellarin (SCU) is a flavonoid glycoside with a range of pharmacological activities, as shown in previous studies demonstrating its anti-inflammatory activity. How SCU impacts the progression of OA, however, has not been explored to date.

Cartilage lesion repair is difficult due to the limited self-repair capability of cartilage and its lack of vascularization. Our previous study established a sandwich model for engineering cartilage with acellular cartilage sheets (ACSs) and chondrocytes. However, there is still debate over which agent achieves the optimal decellularization of cartilage sheets.

Background: The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft.

Article Synopsis
  • The study examines the use of a specific type of flap (bilobed innervated radial artery superficial palmar branch perforator flap) to reconstruct completely degloved fingers after severe injuries.
  • Detailed anatomical research was conducted on cadavers to identify arterial structures and test the flap-raising technique, confirming the presence of key perforators for flap viability.
  • In a trial involving 12 patients, the new flap design was successful in all cases, achieving good functional outcomes without complications or the need for reoperation.

Objective: To investigate the effect of vacuum sealing drainage (VSD) combined with artificial dermis for treatment of the ankle and foot soft tissue defects.

Methods: A total of 15 patients with skin and soft tissue defect of ankle and foot were treated from January 2011 to December 2013, including 10 males and 5 females, with an average age of 32.5 years old ranging from 3 to 55 years old, involving 8 cases by traffic accident, 2 cases by machine accident, 5 cases by crush injury;8 cases with soft tissue exposure, 2 cases with tendor exposure, 5 cases with bone exposure.

Objective: To analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

Methods: From January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3.

Fibroblast growth factor (FGF)21 functions in the maintenance of glucose homeostasis and exerts protective effects on the liver, heat and kidneys. However, the roles of FGF21 in other tissue types are yet to be fully elucidated. The present study detected elevated expression levels of FGF21 in skin tissue.

Objective: To investigate the effectiveness of dorsal pentagonal flap for reconstruction of the web space in congenital toe syndactyly.

Methods: Between January 2009 and June 2014, 10 patients with congenital toe syndactyly were treated for web space reconstruction with dorsal pentagonal flap. There were 6 boys and 4 girls with the average age of 42 months (range, 8 months to 9 years).

Objective: To evaluate the clinical effects by comparing three different fixation methods: tension band, hollow lag screw and anatomical plate.

Methods: From January 2010 to January 2012, 82 patients with olecranon fractures who underwent surgical treatments were followed-up. All the patients were divided into three groups: tension band fixation group (group A), hollow lag screw fixation group (group B), anatomical plate fixation (group C).
