OBJECTIVETo investigate the molecular genetics basis for HLA novel allele HLA-DRB1*1212 in Chinese population.
METHODSGenomic DNA was extracted from whole blood by salting-out method. HLA-DRB1 gene exon 2 was amplified by PCR with group-specific primers from genomic DNA. PCR products were cut back from agarose gels and purified to sequence directly. The polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSO) was performed to confirm the mutations which were detected by sequencing in this study.
RESULTSThe sequencing results showed HLA-DRB1 alleles of the proband as DRB1*090102 and the novel allele. The sequences of the novel allele have been submitted to GenBank (AY899825). Through BLAST analysis, the novel allele was found to be different from DRB1*120101 at position 199A-->C in exon 2, that results in an amino acid change from Ile to Leu at codon 67.
CONCLUSIONThis allele is a novel and has been officially named as DRB1*1212 by the WHO Nomenclature Committee.

OBJECTIVETo study the effect of the Qingxin Kaiqiao fang on learning and memory ability and shape hippocampal nerve cells in Alzheimer disease (AD).
METHODOne handred and fifty mice were divid into five groups: blank group, model group, two groups of treatment by Qingxin Kaiqiao fang (14.82, 7.41 g x kg(-1)), piracetan comparison group (0.42 g x kg(-1)). The model group was orally given AlCl3 (200 mg x kg(-1)) every day. For Qingxin Kaiqiaofang and piracetan groups, AlCl3 treatment was given for 6 days at the beginning, followed by giving orally AlCl3 in the morning and drug in the afternoon for 8 weeks. Then, learning and memory aility, the contents of nitric oxide (NO), NO synthase (NOS) and acetylcholinesterase (AchE) in brain, and morphology of hippocampal nerve cells were investigated.
RESULTLearning and memory ability of Qingxin Kaiqiaofang groups was improved, compared with comparison group; the difference was significant (P < 0.05, P < 0.01). The drug could prevent hippocampal nerve cells from damaged obviously. The contents of NO, NOS and AchE in mice of treatment groups were lower than those of comparison group; the difference was significant (P < 0.05, P < 0.01).
CONCLUSIONQingxin Kaiqiaofang can improve learning and memory ability of AD mice, prote chippocampal nerve cells, and treat Alzheimer disease.

OBJECTIVETo study the expression of centromere protein A (CENP-A) and its significance in hepatocellular carcinoma (HCC) and adjacent non-neoplastic liver tissue.
METHODSThe expression levels of CENP-A mRNA in 20 samples of HCC and adjacent non-neoplastic liver tissue were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and real-time quantitative polymerase chain reaction (qRT-PCR). Immunohistochemical study for CENP-A and p53 proteins was also performed on tissue microarrays containing 80 samples of HCC and adjacent liver tissue.
RESULTSThe expression level of CENP-A mRNA in HCC (0.64 +/- 0.18) was higher than that in adjacent non-neoplastic liver tissue (0.09 +/- 0.09) (t = 12.78, P < 0.01). Of the 80 samples of HCC, 57 cases (71.25%) and 60 cases (75%) expressed CENP-A and p53 proteins respectively. The positivity rates of CENP-A and p53 proteins in non-neoplastic liver tissue were 43.75% (35/80) and 16.25% (13/80) respectively. There was a statistically significant difference in CENP-A and p53 protein expression between HCC and non-neoplastic liver tissue (P < 0.01). The coincident rate between CENP-A and p53 expression was 88.75% (71/80). Expression of CENP-A protein showed a positive correlation with that of p53 protein (r = 0.57, P < 0.01).
CONCLUSIONThe over-expression of CENP-A occurs at transcriptional level and may be related to malignant proliferation of HCC via possible interaction with p53 gene.
