[Chinese experts consensus on the use of oral propranolol for treatment of infantile hemangiomas].

Infantile hemangioma (IH) is one of the most common benign vascular tumors in children. A variety of treatment methods have been documented for the management of IH over the past years, including pharmacotherapy via oral administration or injection of corticosteroids, vincristine, alpha interferon and bleomycin; laser therapy, radionuclide therapy, cryotherapy and excisional surgery. The therapeutic efficacy of each treatment modality is variable, while adverse effects or complications are common and sometimes serious.

A practical guide for diagnosis and treatment of arteriovenous malformations in the oral and maxillofacial region.

Arteriovenous malformations (AVMs) are congenital vascular malformations (CVMs) resulting from birth defects of the vasculature. It is rarely seen, only accounting for 1.5% of all vascular anomalies, and 50% of the lesions are located in the oral and maxillofacial region.

Guidelines for the treatment of head and neck venous malformations.

Venous malformation is one of the most common benign vascular lesions, with approximately 40% of cases appearing in the head and neck. They can affect a patient's appearance and functionality and even cause life-threatening bleeding or respiratory tract obstruction. The current methods of treatment include surgery, laser therapy, sclerotherapy, or a combined.

Effects of nerve growth factor delivery via a gel to inferior alveolar nerve in mandibular distraction osteogenesis.

Inferior alveolar nerve (IAN) injury is a concern in mandible distraction osteogenesis (DO). We have previously demonstrated that repeated local injections of human nerve growth factor beta (NGF-beta) have significantly enhanced the histologic recovery of the IAN in a rabbit model of DO. This study was to further test the effect of a single injection of human NGF-beta delivered via a collagen/nanohydroxyapatite/kappa-carrageenan gel to the recovery of the IAN in DO.

[The preparation of series of the controllable degradation coral-hydroxyapatite (SCHA-200R) and the on its application as the scaffold in bone tissue-engineering].

Objective: Fabricate series of the controllable degradation coral-hydroxyapatite.

Methods: The natural coral undergo a chemical reaction with (NH4)2 HPO4 at high temperature and pressure for different time-lengths. After getting the products, the components and the special structures were analyzed.

Fusion expression of major antigenic segment of JEV E protein-hsp70 and the identification of domain acting as adjuvant in hsp70.

Hsp70 potentiates specific immune responses to some antigenic peptides fused to it. A recombinant hsp70 protein expression vector in methylotrophic yeast, Pichia pastoris, was developed that fused the major antigenic segment of Japanese encephalitis virus (JEV) E protein to the amino terminus of Mycobacterium tuberculosis hsp70. The C-terminal peptide binding domain of hsp70 stimulated Th1-polarizing cytokines, CC chemokines and an adjuvant effect.

[Bone formation by seeding bone marrow stromal cells on the sodium calcium phosphate/beta tricalcium phosphate scaffold].

Purpose: To observe the osteogenesis of sodium calcium phosphate/beta-tricalcium phosphate scaffold loaded with marrow stromal cells in a nude mice subcutaneous model.

Methods: To transform the sintered bovine cancellous bone into NaCaPO(4)/beta-TCP biphasic calcium phosphate ceramic by physical and chemical methods. Bone marrow stromal cells (BMSCs) were obtained by harvesting the cancellous bone from the iliac crest of a rabbit.

[A histologic observation of bone formation induced by subperiosteal implantation of resorbable porous block beta-tricalcium phosphate on calvarial surface in rabbits].

Objective: By the histologic observation of samples, understanding the osteoconductive histologic behaviour and resorbable mechanism of beta-tricalcium phosphate (beta-TCP).

Methods: Porous block beta-TCP samples were implanted into calvarial surface. Tissue slices dyed with methods of HE and Masson's were observed by microscope and compared with hydroxyapatite(HA).

[Transforming the sintered ostrich cancellous bone to multiphasic calcium phosphate ceramic].

Objective: To transform the sintered ostrich cancellous bone(ostrich true bone ceramic, OTBC) to multiphasic calcium phosphate ceramic and study its components and characterization.

Methods: The OTBC blocks were soaked in different concentration of sodium pyrophosphate (Na(4)P(2)O(7).H(2)O,NP) solution and heated to 1100 degrees C to transform its constitution from HAP into multiphasic calcium phosphate ceramics.
