Thirst study was purposed to explore the genetic polymorphism of Chinese Zhuang population at HLA-Cw locus by sequence based typing (SBT). A total of 150 unrelated blood samples from Chinese Zhuang population were subjected to sequencing at exon 2, 3 and 4 of HLA-Cw gene in both directions by using SBT technique established by our laboratory. The purified products of sequencing reaction were run by means of electrophoresis on the ABI 3730 DNA Sequencer and the assignment of HLA-Cw genotype was accomplished by using the Assign 3.5 software. The consensus sequence at exon 2, 3 and 4 of HLA-Cw gene for each sample was imported into the Assign 3.5 software. The results showed that 33.33% of tested samples could obtain an unique genotype, genotype in 63.33% of tested samples with ambiguous results could be assigned by ruling out the rare alleles according to the NMDP Rare Allele List File; however, the final genotype in rest 3.33% of the detected samples could be defined when subjected to further confirmatory testing by PCR-SSP. In this detection 16 HLA-Cw alleles were identified, the common alleles with a frequency of > 10% were Cw*0304 > Cw*0102 > Cw*0801 > Cw*0702. The value for gene diversity (GD) was 0.9297, The frequency for Cw*01, 03, 07, 08, 12, 14 (Cw 1 allele group) and Cw*02, 04, 05, 06, 15, 16, 17, 18 (Cw 2 allele group) was 0.8967 and 0.1032, respectively, which indicated that the Cw 1 allele group is the dominant ligand for KIR in Chinese Zhuang population. 51 genotypes were determined and the distribution of genotype frequency was in line with Hardy-Weinberg principle. It is concluded that the obtained HLA-Cw allele frequency and its distribution characteristics of Chinese Zhuang population can provide valuable data in the studies of anthropology and the association of HLA-Cw with disease.

OBJECTIVETo explore the effect of burying testis in thigh pocket on spermatogenesis.

METHODSGuizhou miniature male pigs at child-bearing period were randomly divided to receive operation of scrotum incision and dissection with the testis burying in thigh pocket (experimental group) or without (control group). 3 months later, testis biopsy was performed on 2 pigs from each group for pathological examination. Then every male pig from both experimental (n = 6) and control group (n = 6) got a mating partner and lived together for 3 months. The fertility of the male pigs was observed. 6 months after operation, testis biopsy was performed again on all the animals from both the groups.

RESULTSBoth at 3 months and 6 months after operation, the pathological examination showed the spermatogenic cells of all stage in contorted seminiferous tubules markedly decreased with no mature sperm in experimental group, while normal spermatogenic cells with mature sperm in control group. After the male pigs lived with mating partners for 3 months, no female pigs staying with the experimental group became pregnant, but the male pigs in control group had a normal fertility.

CONCLUSIONSBurying testis in thigh pocket impedes spermatogenesis in the miniature male pig. So burying testis in thigh pocket is not recommended for patients with scrotum skin defect who wish to remain fertile.

Objective To observe the efficacy and safety of applying sirolimus-eluting stents in emergency percutaneous coronary intervention (PCI) for the patients with acute myocardial infarction (AMI).Methods In total,220 patients with AMI were enrolled in this study at Shanghai Tongji Hospital, divided into two groups,one with bare-metal stent and the other with sirolimus-eluting stent.Cardiovascular fatality,major adverse cardiac events (MACE) and target vessel revascularization (TVR) were observed one and six months after PCI in the two groups.Results There was no significant difference in overall fatality and MACE in the 1~(st) or 6~(th) months after PCI between the two groups.Three cardiogenic deaths occurred in bare-metal stent group with a fatality of 2.8 percent,and five deaths in sirolimus-eluting stent group with a fatality of 4.5 percent in six months after PCI.However,rate of restenosis in those with sirolimus-eluting stents was significantly lower than that of bare-metal stents (6.0 percent vs 16.1 percent,P

Objective　To observe the curative effect and sid e effect of the gastrokinetic agent mosapride citrate by RCT. Methods　 42 cases of functional dyspepsia (FD) were divided into two groups rando mly, the group of mosapride(21 cases):orally administrated mosapride, 5mg, t.i.d for 4 weeks, and the control (21 cases):orally administrated domperidone, 5mg, t.i.d for 4 weeks. Symptoms and side effects were recorded before and at d 14, d 28 after administration of the medicines according to GCP and double blind pri ciple. Gastric empting test was also carried out in randomly selected patients. Results　Mosapride and domperidone were significantly effective on alleviating symptoms of the patient with FD. In mosapride treated group the half emptying time was shortened and the 120 min remain rate was reduced. No sid e effect was found. Conclusion　These results suggest that mosa pride 5 mg t.i.d. is effective and safe on alleviating symptoms of patients with FD and improving the ga stric empting time.

OBJECTIVETo analyze human leukocyte antigen (HLA) polymorphism and search for new alleles in Chinese Han population bone marrow registry donors.

METHODSDNA-based HLA genotyping methods were used including PCR-SSP, BST and molecular cloning.

RESULTSA total of 6965 unrelated donors, 4707 from South China origin and 2258 from north, were typed for HLA-A, B, and DRB1 loci. Seventy-two specificities of HLA alleles were identified. The HLA-A25, A34, A74, B41, B42, B53, B73 and B81 that were rarely reported in previously Chinese population studies were identified in this study. Estimation of gene frequency indicated that the blank gene frequency was less than 0.2% for HLA-A, 0.25% for HLA-B and 0.70% for HLA-DRB1 loci. Three novel alleles were identified and officially assigned by the World Health Organization (WHO) Nomenclature Committee as A*0253N, A*1114 and B*5610.

CONCLUSIONLarge-scale DNA-based HLA genotyping used in bone marrow registry donors is highly accurate and reliable for estimating gene frequency and searching for new alleles. The discrepancy of HLA gene distribution between South and North China Han population showed the necessity of setting the more regions in South and North China to screen the bone marrow registry donors for bone marrow transplant.

OBJECTIVETo investigate the role of D-galactose, especially in the structural and functional changes of the immune system in aging.

METHODSSerum levels of advanced glycation end-products (AGE) were determined by ELISA method. Ultra-structures of thymus and spleen were detected by transmission electron microscopy. MTT method was used to determine the lymphocyte proliferation. IL-2 activity was determined by bioassay. Northern blot was used to detect the IL-2 mRNA levels.

RESULTSSerum AGE levels of D-galactose- (P < 0.01) and AGE-treated (P < 0.05) mice (n = 8) were increased significantly. The ultra-structures of thymus and spleen in D-galactose- and AGE-treated mice showed regressive changes similar to those in the aged control group. The lymphocyte mitogenesis and IL-2 activity of spleen were also decreased significantly (P < 0.01, n = 8). The change of IL-2 activity shown by Northern blot resulted from the change of mRNA expression. The AGE plus aminoguanidine group, however, showed no significant change in these parameters in comparison with the young control group (P < 0.01 or P < 0.05, n = 8).

CONCLUSIOND-galactose and AGE lead to a mimic regression change of aging in the immune system in vivo.

OBJECTIVETo analyze the status of HLA-DPA1 and DPB1 matching for unrelated donor-recipient pairs matched at high-resolution allele level for HLA-A, B, C, DRB1 and DQB1 loci.

METHODSA total of 76 unrelated donor-recipient pairs matching at allele level for HLA-A, B, C, DRB1 and DQB1 loci were subjected to HLA-DPA1 and DPB1 sequence-based typing (SBT). HLA-DPA1and DPB1 matching status at high-resolution allelic level was also analyzed.

RESULTSThe allelic identity ratio for single HLA-DPA1 and DPB1 were 17.1% and 9.2%, respectively. HLA-DPA1 and DPB1 allelic identity ratio were both very low. The majority of unrelated donor-recipient pairs (73.7%) had an incompatibility at 1 HLA-DPA1 allele, 9.2% of pairs had an incompatibility at 2 DPA1 alleles. As for the high-polymorphic HLA-DPB1 gene, 57.9% of studied donor-recipient pairs had an incompatibility at 1 HLA-DPB1 allele, almost 1/3 (32.9%) of them were completely incompatible. When HLA-DPA1 and DPB1 genes were analyzed together, the donor-recipient pairs matched at 2/4 was the most common (51.4%), 4/4 allelic complete matched pairs accounted for 5.6%, and 0/4 matched pairs accounted for 8.3%.

CONCLUSIONOur results indicated that the ratio of HLA-DPA1 and DPB1 complete match in the unrelated donor-recipient pairs matching at allelic level for HLA-A, B, C, DRB1 and DQB1 loci were very low. The effect of HLA-DPA1 and DPB1 matching status on clinical unrelated stem cell transplantation still needs to be elucidated.
