Concordance of identifying the presence or absence of KIR genes by Flow-rSSO and PCR-SBT methods: a comparative study / 中国输血杂志

【Objective】 To study the concordance of identifying the presence or absence of KIR genes using flow reverse sequence-specific oligonucleotide probe (Flow-rSSO) hybridization and sequencing based typing-PCR (PCR-SBT) methods. 【Methods】 A total number of 131 cases of DNA samples from Han population were subjected to identify the presence or absence of all 16 KIR genes by Flow-rSSO method, and then sequenced at coding sequence for all 14 functional KIR genes using our in-house KIR PCR-SBT assay. The concordance of identifying the presence or absence of all functional KIR genes by Flow-rSSO and PCR-SBT was analyzed. Samples with inconsistent initial results were re-tested using the Flow-rSSO commercial kits with different Lot number, and further tested using the PCR-SSP commercial kit. 【Results】 The presence or absence of 14 functional KIR genes for 129 of 131 samples were completely in accordance via the PCR-SBT and Flow-rSSO methods. Two samples, one with 3DL1 negative, the other with both 2DS3 and 2DS5 negative initially-identified by Flow-rSSO, were actually all positive tested by PCR-SBT. Further retest by Flow-rSSO commercial kits with different Lot number and PCR-SSP commercial kit indicated that the two samples were all positive, which agreed well with PCR-SBT results. 【Conclusion】 In this paper, the initial test results of the presence or absence of KIR genes identified by Flow-rSSO for 2 samples were wrong, which indicated the importance of carrying out the quality control for reagents in KIR gene testing.

【Objective】 To explore the polymorphism of HPA-1-6w, HPA-15 and 32bw-35bw in platelet donors in Deyang, Sichuan, and estimate whether to include the detection of 32bw-35bw in the platelet bank. 【Methods】 Polymerase chain reaction with sequenced based typing (PCR-SBT) was used to sequence the HPA-1-6w, HPA-15 and 32bw-35bw loci of 205 platelet donors in Deyang. Allele frequencies were calculated by the direct counting method. The frequencies of HPA-1-6 and 15 alleles in northern and southern Chinese, Japanese and Australian population were compared, and those HPA loci and HPA-32bw-35bw were searched in the Chinese Millionome Database (CMDB) and genomAD to obtain the polymorphism data. Then the Chi-square test was performed with the data of this study through GraphPad Prism 9 software. 【Results】 The allele frequencies of HPA-1b, 2b, 3b, 5b, 6bw and HPA-15b were 0.005(2/410), 0.037(15/410), 0.471(193/410), 0.020(8/410), 0.010(4/410) and 0.461(189/410), respectively, b allele of HPA-32bw-35bw and HPA-4 was not detected. Statistical significance was observed between the HPA-1b allele frequency of this study and northern Chinese, Australian population and genomAD global population sample (P< 0.05, 0.005 vs 0.014 vs 0.145 vs 0.122). The frequency of HPA-2b alleles in this study, Japanese population and genomAD global population samples was 0.037 vs 0.120 vs 0.100, with statistical difference(P<0.05). Comparison of HPA-5b and HPA-6bw allele frequencies with those of genomAD global population showed a statistical difference (P<0.05, 0.020 vs 0.089 and 0.010 vs 0.000 008, respectively). 【Conclusion】 The polymorphisms of HPA-1-6w and HPA-15 of donors in Deyang has characteristics of the southern Chinese. The frequencies of HPA-32bw-35bw were extremely low, which could be excluded from the platelet bank in Deyang.

Genetic diversity of BoLA-DRB3 gene in Colombian creole Hartón del Valle cattle / Diversidad genética del gen BoLA-DRB3 en el ganado criollo colombiano Hartón del Valle / Diversidade genética do gene BoLA-DRB3 em gado crioulo colombiano Hartón del Valle

The objective of this study was to evaluate the genetic diversity of ball-DRB3 gene in the Colombian creole Hartón del Valle cattle. A total of 93 Hartón del Valle (HV), 30 Lucerne (LUC), and 30 Holstein (HOL) animals were evaluated for DRB3 gene polymorphism using the PCR-SBT method. The number of alleles found were 27, 17 and 14 for HV, LUC, HOL, respectively. The most frequent alleles were DRB3*1101 (14.5%) in HV; LUC DRB3 * 0701 in LUC; and *1107, *1501 and *2301 in HOL (11.7%). Expected heterozygosity values were higher than observed, which resulted in a low fixing index, positive F IS (significant only for HV), and no significant deviations from Hardy- Weinberg equilibrium for LUC. The molecular analysis of variance reflected little variation between breeds (3%) and a moderate genetic differentiation (F ST = 0.056 p<0.01). Regarding sequence, LUC was the most diverse breed, no neutral selection is occurring, and none of the breeds is in selection equilibrium. Comparison with reports on other breeds showed high genetic diversity in Colombian breeds. We conclude that HV has high genetic diversity in BoLA-DRB3 locus. The cause of this polymorphism may be due in part to the origin of HV. This high variation can be maintained by selection equilibrium.

El objetivo de esta investigación fue evaluar la diversidad genética del gen BoLA-DRB3 en el ganado criollo Colombiano Hartón del Valle. En 93 animales Hartón del Valle (HV), 30 Lucerna (LUC) y 30 Holstein (HOL) se evaluó el polimorfismo del gen DRB3 usando la metodología PCR-SBT. Se encontraron 27 alelos en la raza HV, 17 en LUC y 14 en HOL. El alelo más frecuente en HV fue el DRB3*1101 (14,5%), en la raza LUC los alelos DRB3*0701, *1107, *1501 y *2301 al igual que el alelo DRB3*0701 en la raza HOL tuvieron la frecuencia más alta (11,7%). Los valores de heterocigocidad esperada fueron más altos que la observada, lo que se tradujo en un valor bajo del índice de fijación, valores de F IS positivos solo significativo en el HV y desviaciones del equilibrio de Hardy-Weinberg no significativos en LUC. El análisis de varianza molecular reflejó poca variación entre razas (3%) y una diferenciación genética moderada (F ST= 0,056 p<0,01). A nivel de secuencia se resalta que, la raza más diversa es LUC, que no se está presentando selección neutral y que ninguna de las razas se encuentra en equilibrio de selección balanceadora. La comparación con otras razas reportadas, mostró alta diversidad genética en las razas colombianas. Se concluye que la raza HV tiene alta diversidad genética en el locus BoLA-DRB3, que el origen del polimorfismo puede deberse en parte al origen de la raza y que esta alta variación puede ser mantenida mediante equilibrio de selección.

Development of apoptosis after small bowel transplantation in rats / 中国康复理论与实践

@#ObjectiveTo investigate the development of apoptosis during ischemia/reperfusion (IR) injury and acute rejection, and to explore the significance of apoptosis in the Graft Mesenteric Lymph Node (GALT) in a rat heterotopic small bowel transplant (SBT) model.MethodsSBT was performed in F344/N rats with either freshly harvested or preserved (4 h, in ringer lactate solution at 4 ℃) syngeneic and allogeneic (Wistar/A-F344/N) grafts. Bowel and GALT samples were collected 2 h after reperfusion and on small bowel transplant postoperative days (POD) 1, 4, and 7. Histopathology assessment of the graft and GALT were prepared for hematoxylin-eosin (H&E) staining. Apoptosis was detected by the TUNEL and the electron microscope. ResultsThe number of apoptotic cells 2 h after reperfusion increased profoundly in association with preservation. After a significant decrease on POD 1, the apoptotic cells rose again between POD 3 and 7 only in allogeneic grafts. On the other hand, the apoptotic cells in allogeneic GLAT markedly increased from POD 1 to day 3; at that time point, neither histological findings of rejection nor increase in apoptotic crypt cells were present in the graft jejunum. ConclusionIR injury and acute rejection may both induce extensive apoptosis. The graft jejunum distinct second increase in apoptosis may be an early and specific sign of acute rejection. Apoptosis of GLAT cells was well correlated with and ahead of progression of acute rejection.

Distribution of HLA-A, B, C Allele and Haplotype Frequencies in Koreans / 대한진단검사의학회지

BACKGROUND: The HLA system is known to be the most polymorphic gene cluster in the human genome. HLA allele and haplotype distribution varies widely among different ethnic groups. In this study, we examined the frequency of HLA class I alleles and haplotypes in 309 healthy Koreans. METHODS: We typed HLA-A, -B, and -C genes at the allelic level in 109 unrelated Korean individuals using a sequence-based typing. With the additional data of 200 healthy Koreans from dbMHC (http: //www.ncbi.nlm.nih.gov/mhc/), allele and haplotype frequencies were estimated by the maximum likelihood method. Serological typing results of 49 individuals were compared with the results highly resolved. RESULTS: A total of 22 HLA-A, 41 HLA-B, and 21 HLA-C alleles were found in this study. Alleles showing frequencies of more than 10% in each HLA locus were A*2402 (22.5%), A*0201 (15.7%), A*3303 (14.4%), A*1101 (11.0%), B*5101 (12.1%), Cw*0102 (18.8%), and Cw*1402 (10.2%). The most common A-B-C haplotypes at a frequency of more than 3% were A*3303-B*5801-Cw*0302 (5.2%), A*2402-B*5101-Cw*1402 (4.5%), A*1101-B*1501-Cw*0401 (4.3%), A*3303-B*4403-Cw*1403 (4.0%), A*3001-B*1302-Cw*0602 (3.7%), and A*0207-B*4601-Cw*0102 (3.2%). Misassignment of HLA-C antigen by serotyping was detected in 11 (22.4%) of 49 individuals. CONCLUSIONS: Our results will be useful as a basic data for studies on anthropology, disease association, and bone marrow transplantation. Misidentification of HLA-C by serotyping is so high that it would be desirable to perform a DNA typing especially in unrelated bone marrow transplantation.

Reliability and Validity of the Korean Version of Short Blessed Test (SBT-K) as a Dementia Screening Instrument / 신경정신의학

We aimed to develop the Korean version of Short Blessed test (SBT-K) by analyzing its reliability and validity, showing its usefulness as a dementia screening instrument. The translation, including back translation procedure, was carried out, keeping the basic structure of SBT. SBT-K. The Korean Version of Blessed Dementia Scale-Activity of Daily Living (BDS-ADL-K) and Clinical Dementia Rating Scale (CDR) were administered to 224 dementia patients and 191 control subjects, and The Korean Version of Consortium to Establish a Registry of Alzheimer's Disease-Mini-Mental State Examination (CERAD-MMSE-K) was to 157 patients and 167 controls. The correlation of SBT-K scores between two raters, correlation between the test and retest after one month, and its internal consistency were analyzed. To verify the concurrent validity of SBT-K, its correlation with each test: CERAD-MMSE-K, BDS-ADL-K, and CDR was analyzed. The sensitivity and specificity for each cut-off point of SBT-K were calculated and the Receiver Operator Characteristic (ROC) curve analysis was done to get its optimal cut-off point. SBT-K was found to have significantly high internal consistency, inter-rater reliability, and test-retest reliability. The significant correlation of SBT-K with each test described above was also shown. Its optimal cut-off point was estimated as 10/11, and the sensitivity and specificity were 0.85 and 0.90, respectively. The ROC curve analysis indicated that the diagnostic efficiency of SBT-K was comparable with CERAD-MMSE-K. We conclude that SBT-K has not only high reliability and validity, but also usefulness as a screening instrument for dementia.
