Chinese Journal of Plastic Surgery.2014;30(6):448-451.

OBJECTIVETo explore the effect of microneedle combined with Lauromacrogol on skin capillary network.

METHODS24 male Leghone (1.5-2.0 kg in weight) were randomly divided into three groups as group A (microneedle combined with Lauromacrogol), B (microneedle combined with physiological saline) , and C(control). The cockscombs were treated. The specimens were taken on the 7th, 14th, 21th , and 28th day postoperatively. HE staining, immunohistochemical staining and special staining were performed for study of the number of capillary and collagen I/III , as well as elastic fibers.

RESULTSThe color of cockscombs in group A became lightening after treatment. The number of capillary decreased as showing by HE staining. The collagen I and III in group B was significantly different from that in group A and C (P < 0.05). Special staining showed proliferation of elastic fibers in group B.

CONCLUSIONSIt indicates that microneedle combined with Lauromacrogol could effectively reduce the capillary in cockscomb without any tissue fibrosis. Microneedle can stimulate the proliferation of elastic fiber, so as to improve the skin ageing process.

Chinese Journal of Plastic Surgery.2014;30(6):442-447.

OBJECTIVEBy observing the adipogenic and angiogenic microenvironment impact on the morphology of newly generated tissue for exploring the key factors which inducing mature adipose tissue regeneration in tissue engineering model.

METHODS24 healthy 6 months' New Zealand rabbits were picked and put into four groups according to different microenvironment. Every group has 6 rabbits and divided as follows: no axial-blood supply fat flap(0 ml), granular fat only(0.6 ml), axial blood vessel only (0.05 ml), axial vascularized fat flap ((0.6 ml). We separated or combined adipogenic and angiogenic environment within these groups. After 8 weeks, samples were harvested for histologic observation including macroscopic observation, volume analysis and HE testing.

RESULTSIn granular fat group, its volume decreased by (0.25 ± 0.10) ml after 8 weeks as the shortage of blood supply and finally it could be enveloped. In axial blood vessel group, its volume increased by (0. 37 ± 0. 04) ml after 8 weeks with fibrous tissue formation as shortage of adipogenic microenvironment. The no axial-blood supply fat flap group grew into(0.12 ± 0.03) ml, which can' t support large volume adipose tissue formation because of lacking independent blood supply. Only axial vascularized fat flap model could generate mature adipose tissue in large volume(3.45 ± 0.48) ml. The number of new capillary in every group was different after 8 weeks. By counting the numbers in every single view, no axial-blood supply fat flap group 15 ± 3.5)and granular fat only group(5 ± 2.5)had a significant difference with axial vascularized fat flap group 22 ± 5) respectively.

CONCLUSIONOnly both adipogenic or angiogenic microenvironment exist could induce mature adipose tissue in large volume in tissue engineering chamber model.

OBJECTIVETo analyze the effect of mandibular distraction on the maxilla growth in children with hemifacial microsomia through measurement with the posterior-anterior cephalometric X-ray films and Three-dimensional CT reconstruction images.

METHODSThe deviation angular of maxilla occlusion plane and nasal base plane from the infra-orbital plane were measured on the posterior-anterior cephalometric X-ray films in 22 patients before and half a year after operation. The vertical distance from the midpoint of 5th teeth alveolar and the lowest point of maxillary sinus to reference plane were measured on 3D reconstruction images in 15 patients. The data were statistically analyzed.

RESULTSOn posterior-anterior cephalometric X-ray films, the cant of occlusion plane were significantly reduced (P < 0.05), While the angular of nasal base plane and the infra-orbital plane had no significant change. On 3D reconstruction images, all the detection points had significantly declined except the lowest point of maxillary sinus on normal side.

CONCLUSIONSDistraction osteogenesis of mandible can promote the growth of the maxilla in children with HFM, the accelerated growth parts include alveolar bone and maxillary sinus.
