OBJECTIVETo explore the expression of GSK-3beta, CDK-5 and PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 after neural stem cells (NSCs) are transformed into neurons.
METHODSTo culture NSCs from the dentate gyrus of newborn rats(24 h) hippocampus in vitro. NSCs of the third passage were induced towards neurons; the expressions of GSK-3beta(pTyr279,216), PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 were tested by the immunofluorescence cytochemical staining after NSCs had been induced for one week; The expressions of GSK-3beta, CDK-5, PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 were detected with RT-PCR.
RESULTSImmunofluorescence cytochemisty showed that neural cells from NSCs which had been differentiated after one week could express GSK-3j (pTyr279,216)and PP2A. Abeta(25-35) could enhance the expression of GSK-3beta(pTyr279,216), meanwhile it also restrained the expression of PP2A. Moreover ginsenoside Rb1 could reverse the affect of Abeta(25-35). RT-PCR found that neural stem cells which had been differentiated after one week could express GSK-3beta, CDK-5, PP2A . The expression of GSK-3beta and CDK-5 rose up and the expression of PP2A weakened when they were treated by Abeta(25-35). However, the effect of Abeta(25-35) was restrained when they were pretreated by ginsenoside Rb1.
CONCLUSIONThese observations indicated that NSCs which were cultured and induced in vitro can express GSK-3beta, CDK-5 and PP2A; moreover Abeta(25-35) and ginsenoside Rb1 can regulate the expressions of GSK-3beta, CDK-5 and PP2A. It hints that cells which differentiated from neural stem cells in vitro have protein phosphorylation regulation system of normal cells.

OBJECTIVETo explore an ideal method for repairing the skin-soft tissue defects according to the different anatomical units of cheek, and find reasonable design principles to transfer the expanded flaps.
METHODSAccording to the location of the defect, we placed 1-3 appropriate expanders nearby, when the flap expanded enough we adopted advanced skin flaps, rotation-advanced skin flaps or transposition skin flaps to repair the defect. In this group of 269 cases, the defects were secondary to hemangioma, various scars, nevus or nevus excision.
RESULTSIn all 269 cheek defects, 305 expanded flaps were developed which included 145 rotation-advanced flaps, 121 advanced skin flaps and 39 transposition skin flaps. 52 of them generated complications, including blood circulation disorder of the distal part of flaps, hematoma, infection, injection, lower eyelid ectropion, expander extrusion and capsule contracture. Mostly, these complications didn't affect the final results.
CONCLUSIONSThe principles presented in this article are the guidelines to treat the skin-soft tissue defect of check with tissue expansion. The satisfied results come from the reasonable flap designs.

OBJECTIVETo analyze the sectional anatomical features of auricular and middle ear malformation in patients with microtia so as to improve the clinical classification and the instruction of surgery.
METHODSFrom Jun. to Dec. 2009, 36 cases with microtia were selected in the center of auricular reconstruction in Plastic Surgery Hospital, including 22 cases of unilateral microtia and 14 cases of bilateral microtia. 22 patients with unilateral microtia were studied with the contralateral healthy ears as controls. Spiral CT was performed for high-resolution scan of the temporal bone. The coronal, sagittal and 3D reconstruction images were created with Mimic software. Several distances and degrees were measured.
RESULTSThe patients were classified by Max classification. The anteroposterior diameter and the vertical diameter of tympanic cavity were (7.75 +/- 1.92) mm and (14.66 +/- 4.75) mm for type I; (6.17 +/- 2.56) mm and(14.35 +/- 5.12) mm for type II; (6.31 +/- 3.40) mm and (9.97 +/- 4.36) mm for type III (P = 0.001). The mastoid pneumatization degree for type I, II, III were 13.33%, 13.64%, 30.77% in sclerotic type, 13.33%, 18.18%, 7.69% in diploe type, 0, 9.09%, 38.46% in composite type, 73.33%, 59.09%, 23.08% in pneumatic type (chi2 = 24.11, P = 0.002). The cover of fenestra vestibuli by facial nerve was 21.43%, 47.62%, 54.55% (chi2 = 23.44, P = 0.002) for type I, II, III. There was a statistical difference between the microtia group and the control group.
CONCLUSIONSAccording to the Max classification, the middle ear malformation changed along the auricular malformation. The anatomical variations was complicated in type II microtia, which should be sub-classified.
