Objective To identify and investigate B(A)02 allele in a patient. Methods Serological tests were performed with standard serological methods in a patient with B(A)02 allele. DNA sequences of all seven exons and exon-intron boundaries of ABO gene were analyzed by polymerase chain reaction (PCR), direct DNA sequencing and sequencing after gene cloning. In order to analyze the allele, PyMOL software was used to establish 3D model of Glycosyltransferases B (GTB). Results The serological results showed the characteristics of B(A) phenotype. DNA analysis revealed that ABO gene of the individual was heterozygous of B(A)02/O01 allele. 700C>G mutation was identified in B101 allele, which resulted in the amino acid substitution P234A in GTB. Through the analysis of the 3D structure of GTB, it was speculated that the P234A replacement affected the intermolecular forces of the 234 amino acid and Met-266, thus changed the conformation of the donor-binding pocket of GTB,that made GTB capable of recognizing and tranferring the GalNac to the H antigen, which can lead to the formation of the weak A antigen on membrane of red blood cells. Conclusion The P234A replacement can affect the spatial conformation of the specific recognition region conformed by Met-266 and Ala-268 residues, which leads to the antigenicity change of the ABO blood group.

OBJECTIVETo evaluate the clinical value of different regional lymph node staging system and to establish a predictive prognostic model for stage III( colon cancer.

METHODSA total of 256 Patients with stage III( colon cancer from January 1999 to December 2008 were identified from the China Medical University Cancer and underwent radical surgery. Based on information on regional lymph nodes, lymph nodes were staged LNR staging using pN stage in the 7th edition of the AJCC, the jN stage of the JGR, and LNR-stage on the basis of Log-rank statistics, respectively. Using the linear trend chi-square test, likelihood ratio Chi-square test, concordant index(c-index) to evaluate the homogeneity, monotonicity, and discrimination power of the staging system. Univariate and multivariate analyses were used to determine the clinical and pathological prognostic impact factors. After relevant diagnostic models were established, the Akaike Information Criterion (AIC) value was calculated to compare and identify the best diagnostic model.

RESULTSLog-rank statistics found that 0.11 and 0.39 were the optimal cut-off point. LNR staging system included LNR1 (LNR<0.11), LNR2 (0.11,0.39), and LNR3(0.39,1). The concordance indices were 0.624 for pN, 0.611 for jN, and 0.700 for LNR. The heterogeneity was the lowest for LNR. Cox regression model was used to establish prognostic models for pN, jN, and LNR, and the AIC was 99.937, 71.631, and 65.548, respectively. The prognostic value was the highest for LNR.

CONCLUSIONLNR staging is the ideal staging system for stage III( colon cancer patients, which is better than the latest version of the current AJCC pN stage and JGR jN staging.
