Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Purpose To detect the expressions of stress induced phosphoprotein 1 (STIP1) and estrogen receptor-α(ER-α) in papil-lary thyroid carcinoma and to analyse the relationship between STIP1 and ER-α. Methods 54 cases of paraffin-embedded tissues of papillary thyroid carcinoma, 18 cases of papillary thyroid carcinoma with lymph node metastasis, 15 cases of Hashimoto’ s thyroiditis, 10 cases of adjacent normal thyroid tissue were collected. The expressions of STIP1 and ER-αwere detected by immunohistochemistry, and the relationship between the expressions and clinicopathological features of papillary thyroid carcinoma was analyzed. Results The expression of STIP1 and ER-α in papillary thyroid cancer group ( 55. 6% and 44. 4%) were higher than that of normal thyroid group (10% and 0) and Hashimoto’s thyroiditis group (8. 3% and 0, all P<0. 05). STIP1 expressions was related to lymph node metastasis ( P<0. 05 ) , while ER-α expression was related to gender, TG-Ab and the merger of nodular goiter, but not related to lymph node metastasis (P>0. 05). The expressions of STIP1 and ER-α in papillary thyroid carcinoma were not related to patients’ age , tumor location, number of tumors, tumer size, invasion of capsule, the concomitant Hashimoto’ s thyroiditis and TPO-Ab ( all P>0. 05). And the expressions of STIP1 was not related to gender, TG-Ab and the merger of nodular goiter (all P>0. 05). A positive correlation was found between the expressions of STIP1 and ER-αin thyroid papillary carcinoma (P<0. 05). Conclusion STIP1 and ER-α in papillary thyroid carcinoma may be related with lymph node metastasis.

Objective To study the expression and change of neuropeptide substance P (SP) during the wound healing of deep partial thickness scalding in diabetic rats. Methods Eighty-four Wistar rats were randomly divided into diabetes mellitus group (n=42) and control group (n=42). Diabetic rat models were established by intraperitoneal injection of streptozotocin (STZ) in diabetes mellitus group, and those in control group were intraperitoneally injected with aseptic citrate buffer solution. Deep partial thickness scalding with diameter of 2 cm on the back were prepared in all the rats. The pre-scalding and post-scalding wound specimens of different time points were obtained, and the percentages of wound closure were calculated. The wound specimens were also obtained for immunohistological staining to compare the areas with positive staining of SP, and ELISA was employed to detect the expression of SP in the wound tissues. Results The percentage of wound closure was significantly lower in diabetes mellitus group than that in control group from 7 days post-scalding (P< 0.01). The areas with positive staining of SP in diabetes mellitus group were much smaller than those in control group at different time points, which was most significant on the seventh day post-scalding[(1 350.93±99.28) μm2 vs(1 715.86± 103.41) μm2](P < 0.01). The expression of SP in the wound tissues was significantly lower in diabetes mellitus group than that in control group at different time points, which was most significant on the seventh day post-scalding[(114.04±9.96) vs(143.39±8.94)](P<0.01). Conclusion The significantly lower expression of SP in wound site may be one of the causes of delayed wound healing in diabetic rats.

The effects of epigenetic modification on the differentiation of islet cells and the expression of associated genes (Pdx-1, Pax4, MafA, and Nkx6.1, etc) were investigated. The promoter methylation status of islet differentiation-associated genes (Pdx-1, Pax4, MafA and Nkx6.1), Oct4 and MLH1 genes of mouse embryonic stem cells, NIH3T3 cells and NIT-1 cells were profiled by methylated DNA immunoprecipitation, real-time quantitative PCR (MeDIP-qPCR) techniques. The histone modification status of these genes promoter region in different cell types was also measured by using chromatin immunoprecipitation real-time quantitative PCR methods. The expression of these genes in these cells was detected by using real-time quantitative PCR. The relationship between the epigenetic modification (DNA methylation, H3 acetylation, H3K4m3 and H3K9m3) of these genes and their expression was analyzed. The results showed that: (1) the transcription-initiation-sites of Pdx-1, MafA and Nkx6.1 were highly methylated in NIH3T3 cells; (2) NIH3T3 cells showed a significantly higher level of DNA methylation modification in the transcription-initiation-site of Pdx-1, Pax4, MafA and Nkx6.1 genes than that in mES cells and NIT-1 cells (P<0.05); (3) NIT-1 cells had a significantly higher level of H3K4m3 modification in the transcription-initiation-site of Pdx-1, Pax4, MafA and Nkx6.1 genes than that in mES cells and NIH3T3 cells (P<0.05), with significantly increased level of gene expression; (4) NIH3T3 cell had a significantly higher level of H3K9m3 modification in the transcription-initiation-site of Pdx-1, Pax4, MafA and Nkx6.1 genes than that in mES cells and with NIT-1 cell (P<0.05), with no detectable mRNA expression of these genes. It was concluded that histone modification (H3K4m3 and H3K9m3) and DNA methylation might have an intimate communication between each other in the differentiation process from embryonic stem cells into islet cells.

Background The pathogenesis of primary open angle glaucoma(POAG) and high myopia are very complex.To construct the regulatory network of virulence genes and relevant genes that involved in pathogenicity are helpful for reveal of the pathogenesis.Objective The aim of this study was to investigate myocilin(Myoc),a gene that contributes to POAG and high myopia in eyes of BXD Recombinant Inbred(BXD RI)mice and construct the regulatory network of Myoc.Methods The affymetrix microarray system was used to detect the differential expression of Myoc in the eyes of C57BL/6J(B6),DBA/2J(D2) and BXD RI mice.Expression quantitative trait loci (eQTL) mapping was performed to construct the regulatory network of Myoc gene.Results The average expression level of the Myoc gene in the BXD strains was 10.83,and the gene exhibited expression levels ranging from 8.39 in BXD55 mice tol 1.43 in B6 mice.The eQTL mapping for the Myoc gene showed a significant likelihood ratio statistic (LRS) of 21.78.The QTL was mapped in chromosome 2,and Myoc was located on chromosome 1,indicating that the Myoc gene was a trans-acting QTL.Olfml2a was identified to be a candidate upstream gene of Myoc by analysis of bioinformatics.Genetic regulatory network analysis demonstrated that a series of genes associated with Myoc probably played roles in the pathogenesis and development of POAG and high myopia.Conclusions The genetical genomics approach provides a powerful tool for constructing pathways that contribute to complex traits,such as POAG and high myopia.
