OBJECTIVETo investigate the aberrance of histone H3 lysine 4 trimethylation (H3K4me3) in patients with IgA nephropathy (IgAN).
METHODSIn 15 patients with IgAN and 15 healthy volunteers, H3K4me3 variations in peripheral blood mononuclear cells (PBMCs) were analyzed using chromatin immunoprecipitation and microarray analysis (ChIP-chip). ChIP real-time PCR was used to validate the microarray results. Quantitative real-time PCR (qRT-PCR) was carried out to examine the correlations between the mRNA expression profiles and H3K4me3 levels.
RESULTSWe identified 83 genes that displayed significant H3K4me3 differences in IgAN patients compared with healthy subjects. Among them, 39 genes showed increased H3K4me3 and 44 genes had decreased H3K4me3 levels. The results of ChIP real-time PCR were well consistent with the microarray data. Quantitative RT-PCR revealed the correlations between the mRNA expressions and the methylation levels of H3K4me3.
CONCLUSIONIgAN patients have significant alterations in H3K4me3, and the genes with aberrant H3K4me3 may provide insights into the pathogenesis of IgAN.

OBJECTIVETo study gene expression profiling in human type I and II endometrial carcinoma.
METHODSSix Affymetrix human genome genechips were utilized to investigate the differences in gene expression profiles between type I and II endometrial carcinoma with bioinformatic analysis.
RESULTSMany genes were highly expressed in estrogen-dependent endometrial carcinoma, and some of them were involved in the metabolism and conversion of estrogen, while some others in estrogen regulation. CYP2C9, for instance, was involved in the conversion of estrogen sulfate to 16-hydroxy sulfate metabolite, DDC in estrogen-dependent pathogenesis of endometrial carcinoma possibly by DDC interaction with AR to enhance steroid receptor transcription.
CONCLUSIONHigh expression of these genes in estrogen-dependent endometrial carcinoma may provide insights into their roles in the pathogenesis and prognosis of this malignancy.

OBJECTIVETo investigate an ideal method for finger reconstruction with extended the second toe flap transfer.
METHODSThe second toe free flap was created, combined with an pedicled skin flap from the fibular side of the great toe inlaid in the ventral side of the second toe, a double-wing flap and the distal part of the metatarsal bone. The composite free flap was transferred by vascular anastomosis for finger reconstruction.
RESULTSThe reconstructed finger exhibited nice looking and better function. The procedure had little influence to the appearance and function of the donor foot.
CONCLUSIONThis method is effective in ameliorating the appearance and function of the reconstructed finger with the second toe transfer.

OBJECTIVETo evaluate the role of gastric mucosa apoptosis in the stress of ischemic stroke, and to discuss the relationship between gastric mucosa apoptosis and gastric barrier.
METHODSTen dogs were artificially made ischemic stroke by operation (IS group), and another 10 shamly-operated dogs were served as control group. Sucrose permeability were measured after the operation. All dogs were sacrificed 24 hours after operation to measure the gastric mucosal apoptosis index, gastric gross classification, and histological score.
RESULTSThe gastric mucosal apoptosis index in the IS group were significantly higher than in the control group (14.83 +/- 4.41 vs. 5.60 +/- 2.61, P < 0.05). The gastric mucosal apoptosis index were correlated with the sucrose permeability (r = 0. 89, P < 0.05) , gastric gross classification (r = 0. 87, P < 0.05), and histological score (r = 0.92, P < 0.05).
CONCLUSIONSAlthough ischemic stroke will not cause the obvious damage in the respiratory and circulatory system, it is responsible for the apoptosis of epithelial cell in the gastric mucosa and gastric barrier dysfunction. The apoptosis index is closely correlated with the damage of the function and morphology of the gastric barrier, indicating that the epithelial cell apoptosis acceleration in the gastric mucosa may result in the damage of gastric barrier function.

OBJECTIVETo investigate the protective effects on allografts and the possible mechanism of adeno-associated heme-oxygenase-1 (AdHO-1) gene therapy against chronic rejection injury.
METHODSEx vivo AdHO-1 gene therapy was performed in vascular and renal transplantation models. The structure and function, the expression of therapeutic genes and proteins, and the immune modulation were analyzed.
RESULTSAdHO-1 gene therapy protected renal transplant against chronic rejection, but the effect was not as remarkable as that in vascular transplant. The transfected empty vehicle aggravated chronic rejection damage in renal transplantation. AdHO-1 decreased the infiltration of macrophages and CD4(+) T cells.
CONCLUSIONSAdHO-1 gene therapy can lessen damage of chronic rejection in allografts. It plays roles by protecting transplants, down-regulating immune response and inducing immune deviation.
