OBJECTIVETo investigate the role of different immunoglobulin- like receptor (KIR)haplotypes in haplo- identical hematopoietic stem cell transplantation (HSCT).
METHODKiller cell KIR genotyping was performed on 468 individuals from 156 unrelated families by PCR-SSP. A total of 624 KIR haplotypes from the parents were used for haplotype analysis. Ninety-two patients received haplo-identical HSCT from one of the parents.
RESULTSThe family study showed segregation of one A haplotype and at least 20 unique B haplotypes. The frequency of haplotype A was 72.92% (455/624). The most commonly observed haplotypes in group B were B1, B2, and B3, present at a frequency of 10.26%, 5.77%, and 4.48%, respectively. Compared to KIR gene matched donors (n=17), grafts from KIR gene mismatched donors (n= 14) had a positive effect on survival after haplo- identical HSCT for AML/MDS patients (OS: 88.2%vs 42.9%,P=0.015; RFS: 88.2%vs 35.7%,P=0.007). No effect was observed for ALL/NHL patients (OS: 76.0%vs 75.0%,P=0.727; RFS: 68.0%vs 65.0%,P=0.866). A significantly lower survival rate was observed for transplants from AA (n=52) and AB1/AB2 donors (n=15), compared to other group Bx donors (n=25) (OS: 53.3%vs 96.0%,P=0.017; RFS: 53.3%vs 92.0%,P=0.019). Meanwhile, the risk of relapse was much higher in AA group (n=52) compared to Bx group (n=40) (25.0%vs 5.0%,P=0.009). A higher risk of TRM was observed in AB1/AB2 group (P=0.012). In addition, transplant from donors carried Cen-B was associated with an increased survival compared with Cen-A homozygous donors (OS: 94.7%vs 68.5%,P=0.036; RFS: 89.5%vs 64.4%,P=0.045).
CONCLUSIONOverall, KIR genotyping and haplotype analyses should be useful for selection of the most optimal donors with favorable KIR gene grafts. KIR gene mismatch donors should be preferred for AML/MDS patients. Selecting donors carried Cen- B and avoiding the selection of donors of KIR genotype AA/AB1/AB2 was strongly advisable for haplo-identical HSCT.

Objective:Establish the decision threshold value of mean fluorescence intensity of anti-human leukocyte antigen(HLA)antibody through statistical analyzing the results of international proficiency testing(PT)organized by American Society for Histocompatibility and Immunogenetics(ASHI).Methods:Single antigen reagent and liquid chip(Luminex)technique were used to detect anti-HLA antibody. A retrospective analysis of the HLA antibody PT results of 55 quality control samples from 11 times organized by ASHI from 2012 to 2019 was reviewed.Results:Among 79 kinds of HLA-I antibodies, 21, 43 and 15 types of HLA-A, B and Cw antibodies were detected respectively, while among 44 kinds of HLA-Ⅱ antibodies, 18, 7 and 19 types of HLA-DRB1, DQB1 and DPB1 antibodies were detected respectively. After analyzing the MFI detection value of different specific antibodies in each PT samples at our laboratory and the coincidence rate of the negative / positive results judged by ASHI through summarizing the results of multicenter participating in the same period, MFI values of HLA antibody were arranged from high to low into the intervals of possible saturation value, positive decision value, positive judgment threshold value, suspicious positive reference value and suspicious negative reference value , according to the coincidence rate of 95%, 90%, 80%, 79%~50% and <50%.Thus, the decision limit value table of HLA specific antibody at our laboratory was established. And 42 kinds of HLA antibody types were detected with complete data.When the MFI values of various HLA-I or HLA-Ⅱ antibodies are found to be 80% or more in the table, it can be used to judge the detection of HLA antibodies. When HLA antibody MFI value reaches the positive decision value, it may have a certain guiding significance for clinical diagnosis and treatment. And when antibody MFI value reaches the saturation value and lies in the suspicious positive or suspicious negative reference threshold, it just suggests that the clinical need for dynamic follow-up of anti-HLA antibody detection.Conclusions:The decision limit value of MFI of laboratory HLA antibody is established based on the international PT experimental results, which is of reference value for the interpretation of experimental results and clinical diagnosis and treatment. A transplant ation center should pay attention to the quality control of comparison test between laboratories in the detection of HLA antibodies.

ObjectiveTo observe the effect of Guben Jiedu prescription (GBJ) on the epithelial-mesenchymal transition (EMT) of lung cancer A549 cells and to explore the mechanism based on phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodThe GBJ-medicated serum was prepared. Cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay to screen the optimal doses of GBJ-medicated serum for further experiment. A549 cells were classified into normal serum group, low-, medium-, and high-dose GBJ-medicated serum groups (2.5%, 5%, and 10% GBJ-medicated serum), PI3K/Akt pathway activator SC79 group, and high-dose GBJ-medicated serum + SC79 group. Cell migration ability was measured by wound-healing assay. The protein expression of E-cadherin, N-cadherin, vimentin, Akt, phosphorylated Akt (p-Akt), glycogen synthase kinase-3β (GSK-3β), and phosphorylated GSK-3β (p-GSK-3β) was detected by Western blotting, and the mRNA expression of N-cadherin and vimentin by Real-time PCR. ResultCompared with the normal serum, GBJ-medicated serum (2.5%, 5%, 10%, 20%, 40%) decreased the viability of A549 cells (P<0.05), and 10%, 5%, 2.5% GBJ-medicated serum was respectively selected for the follow-up experiment. The migration ability of cells in the high-, medium-, and low-dose GBJ-medicated serum groups was lower than that in the normal serum group. The expression of N-cadherin mRNA and Vimentin mRNA in A549 cells in the three GBJ-medicated serum groups was significantly lower than that in the normal serum group (P<0.01). The protein expression of E-cadherin was higher in the high- and medium-dose GBJ-medicated serum groups than in the normal serum group (P<0.01). The three GBJ-medicated serum groups showed lower protein expression of N-cadherin, vimentin, p-Akt, and p-GSK-3β (P<0.01) and lower expression of p-Akt/Akt, p-GSK-3β/GSK-3β (P<0.05, P<0.01) than normal serum group. Compared with the SC79 group, the high-dose GBJ-medicated serum group demonstrated high protein expression of E-cadherin (P<0.01) and low expression of N-cadherin, vimentin, p-Akt, p-GSK-3β, and p-Akt/Akt, p-GSK-3β/GSK-3β (P<0.01). Compared with the high-dose GBJ-medicated serum group, high-dose GBJ-medicated serum + SC79 group showed low protein expression of E-cadherin (P<0.01) and high protein expression of N-cadherin, vimentin, p-Akt, p-GSK-3β, p-Akt/Akt, and p-GSK-3β/GSK-3β (P<0.01). ConclusionGBJ can inhibit the migration and EMT of lung cancer A549 cells by regulating the PI3K/Akt signaling pathway.
