OBJECTIVETo prepare a decellularized whole laryngeal scaffold by utilizing a perfusion-decellularized technique, reseed cells on it, and construct decellularized laryngeal muscles.
METHODSPerfusion decellularized larynxes were obtained by common carotid arterious perfusion with detergents. Then they were performed by macroscopic view, histological examination, scanning electron microscopy (SEM) and cartilage viability. Decellularized laryngeal scaffold were then reseeded with inducted mesenchymal stem cells (MSCs). Composites were transferred into greater omentums of rabbits after one day's adherence and harvested after eight weeks. Macroscopic view, histological examination and immunohistochemistry were performed.
RESULTSPerfusion larynxes became transparent after two hours. Histology and SEM indicated that perfusion method showed better decullularized effect. More vintages and collagen fibers but no intact cell or nuclei were retained in the decellularized matrix. Porosity measured by Image pro plus 6.0 was 80.4% +/- 3.2% (x +/- s). Chondrocyte vitality assay indicated chondrocyte vitality rate in the perfusion group was 86.9% +/- 1.5%. After eight weeks, vascularization formed and integrated cartilage frameworks still remained. Histological examination could clearly show the presence of muscle bundles and vessels. Immunohistochemical examination indicated that sarcomeric-alpha actin expressed positively in corresponding areas.
CONCLUSIONSIt is feasible to reseed MSCs into the decellularized laryngeal muscle matrix for constructing tissue-engineered laryngeal muscles. This in vivo maturation into the omentum could be the first step before in situ implantation of the construct.

OBJECTIVETo evaluate the immunogenicity of the decellularized laryngeal scaffold.
METHODSTwelve perfused, decellularized laryngeal scaffolds were obtained from rabbits through common carotid artery perfusion with detergents. The twelve decellularized laryngeal scaffolds and the twelve fresh larynxes were then implanted in para-laryngeal muscles of rabbits and harvested after two weeks, four weeks, twelve weeks and twenty-four weeks, respectively. Macroscopic view, histological examination and lymphocyte infiltration test were performed.
RESULTSThe decellularized larynxes were implanted and preserved the laryngeal extracellular matrix and laryngeal architecture. The decellularized larynx did not show obvious immunological rejection after implanted into the para-laryngeal muscles of the recipient rabbits. The volume of implanted larynx became smaller but retained cartilage scaffold. The larynxes in the control group presented the serious immunological rejection and the majority tissues of the larynxes were disintegrated and substituted by the fibrous connective tissues after four weeks. The peripheral tissues were damaged and necrotic at different degrees. The quantity of the lymphocyte infiltration in the control group was higher than that in the experiment group and the result had the statistical significance (P < 0.01).
CONCLUSIONSPerfused, decellularized technique can construct a low immune laryngeal cartilage scaffold which could be a satisfactory material for laryngeal repair.

Objective To investigate the genetic polymorphism of 21 autosomal STR loci and DY S391 locus of SiFaSTRTM 23plex DNA ID system in Han population of eastern China and to evaluate its ap-plication value in forensic science. Methods Typing test of 2000 unrelated individuals was performed using SiFaSTRTM 23plex DNA ID system. The population genetic parameters of STR loci were statistically analysed. A total of 3198 parentage confirmed cases were detected with that system and the mutation conditions were observed in 21 autosomal STR loci. Results All the 21 autosomal STR loci showed no significant departure from Hardy-Weinberg equilibrium (P>0.05). The Ho ranged from 0.6175 to 0.9270. The DP ranged from 0.7964 to 0.9869, as well as the PIC distributed from 0.5611 to 0.9123. The CDP was 0.999999999999999. The CPEduo was 0.999997431701961, while CPEtrio was 0.999999999654865. Five alleles were detected in DY S391 locus, with the allele frequency from 0.0040 to 0.7290, and GD was 0.4189. Except D13S317 and D10S1248, seventy-six mutation events were observed at the rest nineteen autosomal STR loci. Among them, seventy-five (98.68%) were one step mutation, and only one (1.32%) was three steps mutation. The mutation rate ranged from 0.2465×10-3 to 2.7114×10-3, and the averaged mutation rate was 0.8921×10-3 (95% CI: 0.70×10-3-1.10×10-3). In 33 trio mutation cases, the proportion of the paternal mutation and the maternal mutation was 2.09:1. Conclusion The involved STRs are highly polymorphic in Eastern Han population with acceptable mutation rates by the SiFaSTRTM 23plex DNA ID system, which is suitable for paternity testing and individual identification.

OBJECTIVETo screen low molecular weight protein biomarkers relevant to portal vein tumor thrombi (PVTT) in serum of hepatocellular carcinoma (HCC) patients.
METHODSSerum samples were obtained from 12 healthy volunteers, 12 HCC patients without PVTT and 12 HCC patients with PVTT. Using two-dimensional gel electrophoresis (2-DE) in which the second dimension was 16% SDS-PAGE, serum protein images of the 3 groups were analyzed by ImageMaster software. The differential protein spots were further identified by MALDI-TOF MS/MS.
RESULTSComparing the results using 12.5% SDS-PAGE gel, there were more protein bands (between 3 x 10(3) and 20 x 10(3)) and low molecular weight (MW) protein spots (less than 20 x 10(3)) were clearly shown in the 16% SDS-PAGE gel. Fifteen differential protein spots representing 5 proteins were found in the 3 groups by inter-class comparison and they were then identified. Compared with those in the healthy group, apolipoprotein A-I, lipoprotein CIII, transthyretin and DNA topoisomerase II were all down regulated in HCC groups and haptoglobin-2 was over expressed. All 5 proteins decreased more in the PVTT group than in the non-PVTT group.
CONCLUSIONThe expression of low MW serum protein obviously changes in the beginning and in the progressive stage of HCC, and differentially expressed low MW proteins might be potential biomarkers in an early prognostic prediction and surveillance in the treatment for HCC and PVTT.
