[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.

Immunological Journal 2025;41(5):337-344
Objective To explore the correlation between cold-induced RNA binding-protein(CIRP)and NF-κB levels with cognitive dysfunction in elderly patients with ischemic cerebral small vessel disease.Methods 135 elderly patients with ischemic cerebral small vessel disease admitted to our hospital from March 2021 to June 2024 were selected as research subjects.They were divided into a cognitive normal group(n=48)and a cognitive impairment group(n=87)based on whether cognitive dysfunction occurred.Multiple linear regression was used to analyze the relationship between cognitive impairment and inflammatory indicators,while the dose-response relationship of CIRP and NF-κB with cognitive impairment were estimated using restricted cubic spline method.The cognitive impairment group was further divided into mild cognitive impairment group(n=30),moderate cognitive impairment group(n=32),and severe cognitive impairment group(n=25)based on the severity of the condition.Ordered regression analysis was used to investigate the impact of CIRP and NF-κB on patient's condition;ROC curve was used to evaluate the predictive value of CIRP and NF-κB for moderate to severe cognitive impairment,and explore the mediating role of inflammation related factors between CIRP/NF-κB and mini-mental state examination(MMSE)scores.Results TNF-α,IL-6,IL-1β,CIRP and NF-κB are all factors affecting cognitive impairment(P<0.05).CIRP and NF-κB were significantly positively correlated with TNF-α,IL-4,IL-10,IL-1β,MCP-1,TGF-β1 and hs CRP(P<0.05),and significantly negatively correlated with TGF-β1(P<0.05).The correlation of CIRP and NF-κB levels with cognitive impairment showed a non-linear dose-response relationship(P<0.05).There was still an independent correlation(P<0.05)of TNF-α,IL-6,IL-1β,CIRP and NF-κB with the severity of cognitive impairment.High levels of CIRP and NF-κB showed a synergistic effect with high levels of TNF-α,IL-6 and IL-1 β.The AUC value of CIRP and NF-κB for predicting severe cognitive impairment were 0.745 and 0.792,respectively,with a combined prediction AUC of 0.840.TNF-α,IL-4,IL-10,IL-1β,MCP-1,TGF-β1 and hs CRP play a mediating regulatory role between MMSE score and CIRP/NF-κB.Conclusion CIRP and NF-κB participate in the regulation of inflammatory responses and are closely related to cognitive dysfunction and severity of elderly patients with ischemic cerebrovascular disease.Monitoring the changes of CIRP and NF-κB are beneficial for clinical evaluation of patients' cognitive function.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

Objective To investigate the expression changes of T-cell exhaustion-related genes in multiple myeloma(MM)and their potential causal relationships.Methods A bidirectional summary-level Mendelian randomization(MR)analysis was used to explore the causal relationship between T-cell exhaustion and MM.The eQTL data and genome-wide association study(GWAS)were used to summarize data,and corresponding single nucleotide polymorphisms(SNPs)were extracted as instru-mental variables.Four methods,namely inverse variance weighted(IVW)method,MR Egger,weighted median,and weighted mode were used to assess the reliability of the causal relationship.The robustness of the results was validated using Cochran's Q heterogeneity test and pleiotropy test.In cel-lular models,RNA interference was used to silence key target genes,and phenotypic changes such as myeloma cell viability,colony-forming ability,and apoptosis were observed to experimentally confirm the causal effects revealed by MR.Results The genes PRDM1,ENTPD1,PTPN11,and HLA-B were involved in the T-cell exhaustion process in MM.The presence of the PRDM1 gene(OR=0.998 5,95%CI,0.997 1 to 0.999 8,P=0.024 6)may reduce the risk of MM,whereas ENTPD1(OR=1.000 4,95%CI,1.000 1 to 1.000 7,P=0.015 8),HLA-B(OR=1.000 4,95%CI,1.000 1 to 1.000 8,P=0.012 4),and PTPN11(OR=1.002 5,95%CI,1.001 0 to 1.003 9,P=0.001 2)were associated with an increased risk of MM.Real-time quantitative polymerase chain reaction showed overexpression of PTPN11 in MM cell lines and patients' samples.By assessing cell viabili-ty,colony formation and detecting apoptosis,it was found that inhibiting PTPN11 promoted apopto-sis in MM cell lines.Conclusion A causal relationship exists between T-cell exhaustion and MM.Targeted interventions against specific T-cell exhaustion-related genes may help reduce the incidence of MM.

Objective To analyze the impact of digital conversion of screen-film chest radiographs on image quality in patients with pneumoconiosis. Methods Ten high-kilovoltage screen-film chest radiographs from pneumoconiosis patients were digitally converted using three devices, including a digital single-lens reflex camera, a smartphone, and a medical film scanner. The image quality and optical density values before and after image adjustment were compared across different image formats. Results Before adjustment, among the 30 JPEG images, 24 had diagnostic defect areas and 26 had unqualified optical density values. In RAW format, optical density values were not qualified in 18 out of 30 images. In DICOM format, optical density values were not qualified in nine of ten images. After adjustment, optical density values were not qualified in 13 JPEG images, 12 RAW images, and one DICOM image. Comparisons of chest radiograph quality grade distributions before and after adjustment showed significant differences for all three image formats (all P<0.05). Conclusion After being digitally converted by taking images in RAW format with digital photographic equipment and undergoing post-processing adjustment, the quality of screen-film chest radiographs for pneumoconiosis can meet the diagnostic requirements.
