Results The M-value of insulinoma group was significantly higher than that of control group(P0.05).The M-value and MBG of diabetes group were higher than those of insulinoma group and control group(P

OBJECTIVETo summarize our clinical experience in adult-to-adult living donor liver transplantation (ALDLT).

METHODSClinical data of 12 patients with ALDLT performed in our center from September 2000 to June 2005 were analyzed, retrospectively.

RESULTSLeft lobe (segments II, III, IV, including the middle hepatic veins) transplantation was performed in 3 patients and right lobe (segments V, VI, VII, VIII, with or without the middle hepatic veins) transplantation was performed in 9 patients. Donors: There were no operative deaths. The median operative time was 6.20+/-1.40 hours and their blood loss ranged from 300 ml to 1200 ml. Postoperative complications included biliary fistula (1 donor) and wound fat liquefaction (1 donor). During a 6-12 months follow-up, no long-term complications were found. Recipients: The operating time ranged from 5 to 11 hours and their blood loss ranged from 800 to 7000 ml. Modified outflow reconstruction, microvascular reconstruction of the hepatic artery and duct-to-duct biliary reconstruction were done during the recipient operations. The median cold ischemia time was 1.90+/-0.50 hours. The median anhepatic phase of recipients was 1.63+/-0.43 hours. Graft/recipient weight ratio (GRWR) was (1.20+/-0.26)%. One recipient presented a postoperative complication of biliary fistula and another recipient died 1 month after the operation from serious infection. The other 11 recipients had long-term survivals.

CONCLUSIONALDLT is an effective treatment for decompensated end-stage liver disease patients and is relatively safe for the donors.

OBJECTIVETo analyze the association of variants of hepatocyte nuclear factor-1alpha (HNF-1alpha) gene with type 2 diabetes in Chinese population.

METHODSIn 152 unrelated type 2 diabetes patients and 93 unrelated controls, eleven single nucleotide polymorphisms (SNPs) were identified and genotyped. Statistical analyses were performed to investigate whether these SNPs were associated with diabetes status in our samples.

RESULTSIn the individual SNP study, no SNP differed significantly in frequency between type 2 diabetes patients and controls. In the haplotype analysis, two haplotype blocks were identified. In haplotype block 1, no evidence was found between common HNF-1alpha haplotypes and type 2 diabetes. However, in haplotype block 2, a common haplotype GCGC formed by four tagging SNPs (tSNPs) was found to be associated with decreased risk of type 2 diabetes (odds ratio [OR] 0.6011, 95% confidence interval [CI] 0.4138-0.8732, P = 0.0073, empirical P = 0.0511, permutation test). A similar trend was also observed in the diplotype analysis, indicating that the increasing copy number of the haplotype GCGC was associated with the decreased frequency of diabetes (P = 0.0193).

CONCLUSIONThe results of this study provide evidence that the haplotype of HNF-1alpha decreases the risk of type 2 diabetes in Chinese individuals.

OBJECTIVETo found new interface of human hepatocyte/poly propylene with good cytocompatibility for made polypropylene hollow fibers bioreactor of bioartificial liver in future.

METHODSUsing the macromolecular hydroperoxide groups on the polypropylene membrane surface as initiators, acrylamides were polymerized on the polypropylene membranes, under induction by both UV irradiation and Fe2+ reduction. Growth characteristics of human hepatocyte L-02 were detected when it was cultured on polystyrene, polypropylene and modified polypropylene membrane surface.

RESULTSWater contact angle measurement of the polypropylene and the modified polypropylene membranes decreased from (72 +/- 5) degrees to (30 +/- 4) degrees , which indicated that the hydrophilicity of the membrane was improved obviously after the grafting modification. Human hepatocyte L-02 could not adhere and spread on modified polypropylene membrane surface, and grown in spheroidal aggregate with higher density and higher proliferation ratio measured by MTT method.

CONCLUSIONSAcrylamide polymerized on the polypropylene membranes is a good method which not only improved human hepatocytes cytocompatibility but also found a new simple culture method with spheroidal aggregate culture of human hepatocyte.

OBJECTIVETo investigate the relationship between the vascular endothelial growth factor A gene (VEGFA) rs9369425 single nucleotide polymorphism (SNP) and type 2 diabetes in Chinese Han population.

METHODSOne thousand eight hundred and ninety two type 2 diabetes patients and 1808 controls with normal glucose were recruited in this study. Phenotypes including body mass index, waist, waist hip ratio, plasma glucose and serum insulin levels of blood obtained both at 0 and 120 minute during standard 75-gram glucose oral glucose tolerance tests, were analyzed. Insulin resistance and beta cell function were assessed by homeostasis model assessment (HOMA-IR and HOMA-B). Genotyping was performed by time-of-light mass spectrum using a Sequenom platform.

RESULTSThe frequencies of minor allele G in the diabetic patients and controls were 10.8% and 11.3% respectively. No significant difference of allele distribution was detected between the cases and controls (P=0.5086). No significant difference (P>0.05) was detected on the association between rs9369425 SNP and clinical phenotypes.

CONCLUSIONVEGFA rs9369425 was not associated with type 2 diabetes in Chinese Han population. Whether there is association in any other loci in this gene remained to be investigated.

OBJECTIVETo apply linkage disequilibrium (LD) maps to associations studies with high throughput single nucleotide polymorphisms (SNPs).

METHODSSeven hundred and fifty-four SNPs were genotyped in 160 Shanghai Chinese. LD maps were constructed in cases and controls separately. By comparing the decline of LD unit with distance between the two groups, disease susceptible loci were estimated. This method was compared with traditional analyses including LD analysis, single SNP and haplotype analyses.

RESULTSThe analysis of LD maps could detect the chromosome regions with different LD patterns between the cases and controls. The alleles and/or haplotypes frequencies of SNPs within the regions had significantly different distributions or trends of significantly different distributions.

CONCLUSIONThis method may be applied to analyze the data from association studies with high throughput SNPs genotype information.

OBJECTIVETo investigate the relationship between adiponectin receptor 1 gene (ADIPOR1) single nucleotide polymorphism (SNP) and glucose metabolism and insulin resistance in the Chinese.

METHODSThe genotypes of -3881T/C of ADIPOR1 were determined through polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) in 664 Chinese in Shanghai. Among them, 370 were subjects with normal glucose tolerance and 294 were newly diagnosed diabetic patients without taking any drug. Phenotype measured were: height, weight to calculate body mass index; systolic blood pressure and diastolic blood pressure; plasma glucose level, serum insulin and C-peptide levels of blood obtained both at 0 and 120 minute during a standard 75-gram glucose oral glucose tolerance test. Insulin resistance and beta cell function were assessed by homeostasis model assessment (HOMA-IR and HOMA-B).

RESULTS(1) The frequencies of two alleles did not differ between the type 2 diabetic patients and ones with normal glucose tolerance (P is 0.6749). (2) The frequency of C allele is significantly lower in type 2 diabetic patients with insulin resistance compare with those without insulin resistance (P is 0.0121). (3) In type 2 diabetic patients, the C allele carriers had a significantly lower diastolic blood pressure (P is 0.0466) and HOMA-IR (P is 0.0498). (4) In subjects with normal glucose tolerance, the C allele carriers had a significantly lower fasting plasma glucose (P is 0.0140).

CONCLUSIONThese findings suggest that variant of ADIPOR1 plays a role in glucose metabolism and insulin resistance in the Chinese.
