Objective To evaluate the heterozygous ambiguity resolution primers (HARPs) method in resolving ambiguous genotyping results of human leukocyte antigen (HLA) genes in Chinese Hart population, and choose some appropriate HARPs primers. Methods HLA-A, HLA-B and HLA-DRB1 genes of 416 southern Chinese Han individuals were genotyped by sequence-based-typing(SBT) method and then the ambiguous genotyping samples were sequenced again by HARPs primers provided by American Atria company. Results The percentage of ambiguous genotyping samples resolved by HARPs for HLA-A, HLA-B and HLA-DRBI locus was 86.3% (132/153), 73.9% (130/176) and 38.1% (85/223) respectively. Among them, 48.5% (64/132)HLA-A, 80.0% (104/130)HLA-B and all HLA-DRB1(85/85)samples only need one primer, 47.7 % (63/132)HLA-A and 20.0% (26/130)HLA-B samples need two primers. Three to six different HARPs primers can resolve more than 90% ambiguities. Conclusion HARPs is a convenient method and could be a routine method to resolve ambiguities for HLA-A, HLA-B and HLA-DRB1 genes genotyped by SBT in Chinese Han population.

BACKGROUND: The judgment of the engraftment of hematopoietic stem cells after transplantation mainly depends on various genetic labeling in vivo, which are different in sensitivity and effectiveness, thus a method with powerful differential ability, high sensitivity and not restricted by sex is to be established.OBJECTIVE: To observe the DNA genetic loci of short tandem repeat in the blood samples of both donors and recipients before allo-hematopoietic stem cell transplantation and those of recipients at different time points after transplantation.DESIGN: An observation measurement.SETTING: Laboratory of Immunogenetics, Shenzhen Institute of Transfusion Medicine, Shenzhen Blood Center.PARTICIPANTS: Blood samples of 18 pairs of donors and recipients, who were successfully matched and accepted hematopoietic stem cell transplantation, were selected from the Laboratory of Immunogenetics, Shenzhen Institute of Transfusion Medicine, Shenzhen Blood Center from February 2004 to December 2005. Among the 18 patients, there were 10 males and 8 females, with a mean age of 35 years old, including 6 cases of them were donated by relatives with blood relationship, and 12 cases by volunteers without blood relationship. Informed consents were obtained from all the participants.METHODS: The blood samples of both donors and recipients before transplantation and the blood samples of recipients after transplantation were collected, and the fluorescence labeling short tandem repeat technique was used to detect the 15 loci for short tandem repeat and Amelogenin sex locus, so that the differential loci between the donor and recipient could be screened. The engraftment and dynamic changes of the short tandem repeat genes of the donors in the recipients after transplantation were observed, the times for the earliest occurrences of short tandem repeat genes of the donors and the complete chimerism were recorded.MAIN OUTCOME MEASURES: ① Differential genes between the donors and recipients before transplantation;②Times for the earliest occurrences of short tandem repeat genes of the donors and the complete chimerism.RESULTS: All the 18 pairs of donors and recipients were involved in the final analysis of results. Satisfactory results of the typing at the 15 loci for short tandem repeat and 1 sex locus in the 18 pairs of samples of both donors and recipients before transplantation and the sample of the recipients after transplantation respectively. Averagely 12.4 (8-15) differential loci for short tandem repeat could be distinguished between the donors and recipients. ②After transplantation, short tandem repeat genes could be detected the earliest at 8 (5-14) days averagely, It took 14 (9-23) days averagely for short tandem repeat loci to convert from recipient type completely into donor type, and the engraftment converted from the recipient chimerism types completely into the donor types.CONCLUSION: The fluorescence labeling compound amplification of short tandem repeat technique can precisely measure the number of PCR products, describe the engraftment of hematopoietic stem cells and the whole process of development. It can also provide accurate and timely information for the early judgement of engraftment, predicting failure of transplantation and controlling recurrence.

Objective To investigate the expression of hypoxia inducible factor 1α (HIF-1α) and glucose transporter 1 (GLUT1) in lung adenocarcinoma and its correlation with tumor metastasis. Methods SP immunohistochemistry was used to detect GLUT1 and HIF-1α protein expression in 125 lung adenocarcinoma, including 41 cases without metastasis, 38 cases with lymphatic metastasis and 46 cases with brain metastasis. The correlation of GLUT1 and HIF-1α in lung adenocarcinoma metastasis was analyzed by using x 2 test and Pearson correlation analysis. Results Most lung adenocarcinoma were histologically heterogeneous, which contained more than one adenocarcinoma type. 73.2 % (30/41) cases were acinar predominant adenocarcinoma in lung adenocarcinoma without metastasis; 53.6 % (15/38) cases were acinar predominant adenocarcinoma and 26.3 % (10/38) cases were solid predominant adenocarcinoma in lung adenocarcinoma with lymphatic metastasis; 47.8 % (22/46) cases were papillary predominant adenocarcinoma and 34.8 % (16/46) cases were solid predominant adenocarcinoma in lung adenocarcinoma with brain metastases. The expression level of GLUT1 and HIF-1α in lung adenocarcinoma with lymphatic metastasis group was higher than that of the group without tumor metastasis (P< 0.05); the expression of GLUT1 and HIF-1α were positively correlated (r=0.407, P=0.000). Conclusions Papillary adenocarcinoma is the most histological type in lung adenocarcinoma with brain metastasis, suggesting that papillary adenocarcinoma is more prone to brain metastasis. The expression of GLUT1 and HIF-1α play an important role in lymph node metastasis and brain metastasis of lung adenocarcinoma.

Objective:
To study the expression and mechanism of long-chain non-coding RNA PVT1 in tumor by bioinformatics analysis and experimental verification, and to provide new ideas for the study of the pathogenesis of tumors.
Methods:
The expression of PVT1 in 14 common tumors was downloaded from starBase v2.0 public database, which also was verified by PVT1 RNA-in situ hybridization.The upstream transcription factors, the downstream target microRNA(miRNA) for PVT1 and the target genes for the target miRNAs were predicted and analyzed by using bioinformatics based on the database of UCSC Genome Browser, HMDD v2.0, miRTar Base, JASPAR databases.
Results:
StarBase database analysis and RNA in situ hybridization showed that PVT1 was highly expressed in kidney clear cell carcinoma and colon and rectal adenocarcinoma. PVT1 was regulated by the upstream transcription factors CREB1, Atf1, SP1, KLF5, STAT3, while it could control the expression of the downstream target miR-16. bcl-2, VEGFA, CCNE1, CCND1 and SHOC2 showed an interaction with the transcription factor of PVT1, which formed a feedback regulatory pathway.
Conclusions
PVT1 is highly expressed in kidney clear cell carcinoma and colon and rectal adenocarcinoma.The predictive analysis of bioinformatics demonstrates that transcription factor/PVT1/miR-16/target gene signal axon may be an important molecular mechanism, which provide a valuable clue for further functional mechanism research of long-chain non-coding RNA.

OBJECTIVETo study the expression and prognostic significance of ERG and SPINK1 expression in endocrine-treated prostatic cancer.
METHODSProstatic needle biopsies from 118 prostatic cancer patients primarily treated with endocrine therapy were reviewed. Immunohistochemical study for ERG and SPINK1 protein was carried out.
RESULTSCo-expression of ERG and SPINK1 was not observed. The frequency of ERG protein expression in the 118 biopsies studied was 9.3% (11/118). The positive expression correlated with T stage (P=0.04) but not with patient age at diagnosis, prostatic specific antigen level, Gleason's score, M stage, tumor area and progression-free survival. Positive expression of SPINK1 was demonstrated in 11.0% (13/118) of the biopsies. SPINK1-positive cases carried a significantly shorter progression-free survival, as compared with SPINK1-negative cases (P=0.022). The expression was not associated with any other clinicopathologic variables. The following expression pattern showed statistically significant correlation with the clinical progress (P=0.029): ERG+/SPINK1- (11/118, 9.3%), ERG-/SPINK1+ (13/118, 11.0%) and ERG-/SPINK1- (94/118, 79.7%).
CONCLUSIONSERG and SPINK1 proteins are mutually exclusive.SPINK1 expression is associated with more aggressive clinical behavior and can serve as a prognostic biomarker in prostatic cancer.
