Objective: To review the current development of artificial intelligence (AI) technology in the field of transfusion medicine. Methods: A systematic search was conducted in the Clarivate Web of Science Database from inception to December 2024 for literature related to AI and transfusion. A total of 4 775 publications were identified. Based on inclusion and exclusion criteria, 133 original studies were ultimately included and analyzed using a narrative synthesis approach. Results: Research on AI in transfusion has surged since 2020 (accounting for 77% of all publications), with China ranking second globally in publication volume. Among the included studies, 69.2% focused on predicting individual transfusion needs, followed by inventory management (8.3%), diagnosis and prediction of adverse transfusion reactions (6.0%), factors influencing transfusion outcomes (5.3%), blood group identification (5.3%), blood quality testing (4.5%), and precise blood volume measurement (1.5%). Additionally, 4.5% of the studies were published in journals with an impact factor greater than 10; 19.5% developed software or applications; 31.5% were multi-center studies; 48.1% utilized decision tree methods, while 31.5% employed neural network approaches; and 14.2% conducted external validation of the algorithms. Conclusion: AI demonstrates significant potential in transfusion risk prediction, decision support, and blood management. However, challenges remain, including limited model generalizability, insufficient algorithm interpretability, and barriers to clinical translation. The deep integration of AI with transfusion medicine will accelerate the advent of precision transfusion era, maximizing blood resource utilization, reducing waste, and ensuring transfusion safety.

[Objective] To investigate the implementation of emergency transfusion strategy of uncrossmatched type O suspended RBCs based on the single-center clinical practice, which is "emergency transfusion is initiated by the authorized doctor of the emergency department, and no more than 4 U of type O uncrossmatched suspended RBCs are issued within 15 minutes in the transfusion department"(referred as the Practice), so as to provide reference for blood management. [Methods] A retrospective analysis of the information of patients who received uncrossmatched type O suspended RBCs in West China Hospital of Sichuan University from August 2019 to April 2024 was conducted. The analysis included reasons for emergency blood transfusion, time of receiving transfusion application and blood distribution, total bilirubin, indirect bilirubin, lactate dehydrogenase before and after transfusion, blood group of patients, and disease outcome. [Results] From August 2019 to April 2024, 39 cases applied for emergency transfusion of type O suspended RBCs, and a total of 90 U uncrossmatched suspended RBCs were transfused. All patients were Rh(D) positive, including 14 cases of blood group A, 6 cases of blood group B, 16 cases of blood group O, 2 cases of blood group AB, one case of undetermined blood group, and 2 cases with positive antibody screening. The main cause of emergency transfusion of type O suspended RBCs was traffic accident, accounting for 46% (18/39), with a mortality rate at 51.28% (20/39). The cause of death was primary injury, and no adverse reactions were reported. There was no significant difference in total bilirubin (TBIL), indirect bilirubin (IBIL) and lactate dehydrogenase (LDH) before and after blood transfusion (P>0.05). The median duration from admission to receiving transfusion application was 30.20 minutes, and 5.30 minutes from receipt of the application to blood distribution. [Conclusion] The single-center based Practice is safe, but there is room for optimization before the link of blood transfusion application sent to the transfusion department when applying for emergency transfusion of type O suspended RBCs.

Objective To investigate the expression levels of serum hemoglobin β(HBB)in hepatocellular carcinoma(HCC)patients and its correlation with topoisomeraseⅡα(TOP2A)gene.Methods A total of 48 HCC patients visited the Second Affiliated Hospital of Nantong University from August 2023 to September 2024 were selected as the HCC group,and 32 healthy individuals who underwent physical examination during the same period were selected as the healthy control group.Their blood samples were collected,and the ex-pression levels of serum HBB and TOP2A genes were detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).Then,the relationship between the expression of HBB gene and clinicopathological parameters of the patients was ana-lyzed.The Kaplan-Meier Plotter database was used to evaluate the relationship between the expression of HBB gene and the prognosis of HCC.The diagnostic value of the expressions of serum HBB and TOP2A genes for HCC was assessed by the receiver operating charac-teristic(ROC)curve.Spearman rank correlation analysis was used to evaluate the correlation between the expressions of serum HBB and TOP2A genes in HCC patients.The regulatory effect of HBB gene on TOP2A gene was verified by the cell experiment.Results The expression levels of serum HBB gene in HCC patients(0.097[0.055,0.155])were significantly lower than that in healthy controls(1.029[0.625,1.434],U=19,P＜0.001).The expression levels of serum TOP2A gene in HCC patients(1.810[0.825,3.623])were significantly higher than that in healthy controls(1.047[0.604,1.364],U=495,P=0.007).The expression level of serum HBB gene in HCC patients was significantly negatively correlated with that of TOP2A gene(ρ=-0.384,P=0.007).The analysis results of clinicopathological parameters showed that the expression level of HBB gene was only related to tumor size(χ2=4.090,P＜0.05).The Kaplan-Meier survival analysis showed that the 5-year overall survival rate of the patients with low expression of HBB gene was signifi-cantly lower than that with high expression(HR=0.680,95%CI:0.470-0.970,P＜0.05).The analysis of the ROC curve showed that the area under the ROC curve(AUCROC)of HBB gene in diagnosing HCC was 0.987(95%CI:0.963-1.000).When the cut-off value was 0.228,its sensitivity was 100%and specificity was 97%.The AUCROC of TOP2A gene for the diagnosis of HCC was 0.677(95%CI:0.559-0.797).When the cut-off value was 1.285,its sensitivity was 65%and specificity was 75%.The combined detection of HBB and TOP2A genes for the diagnosis of HCC had an AUCROC of 0.988(95%CI:0.965-1.000).When the cut-off value was 0.657,its sensitivity was 100%and specificity was 97%.The cell experiment results showed that the overexpression of HBB gene could inhibit the expression of TOP2A gene,while the knockout of HBB gene had the opposite effect.Conclusion HBB gene is lowly expressed in the serum of HCC patients and is significantly negatively correlated with the expression of TOP2A gene.

Objective To observe the effect of Baduanjin exercise on depression,sleep quality and life quality of patients with breast cancer in the rehabilitation period.Methods A total of 76 breast can-cer patients in postoperative rehabilitation were randomly divided into an intervention group of 38 with 2 dropping out,and a control group of 38 with 3 dropouts.Both groups received routine nursing and rehabilitation after breast cancer surgery,while the intervention group additionally practised Baduanjin for 6 weeks.The Beck Depression Inventory-Ⅱ(BDI-Ⅱ-C),Pittsburgh Sleep Quality Index(PSQI)and Quality of Life Questionnaire Core 30(EORTC QLQ-C30)were used to evaluate both groups be-fore,as well as 3 and 6 weeks after intervention.Results After 3-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimen-sion of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the scores of physical,emotional,cognitive,social and role function in EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Three weeks lat-er,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimension of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the various scores of EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Compared with after 3-week intervention,after 6-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of its all dimensions except for the sleep disorder dimension of the intervention group decreased significantly,while all dimension scores of EORTC QLQ-C30 except the cognitive function dimension increased sig-nificantly(P<0.05 for all).Conclusion Baduanjin is feasible in improving the sleep and life quality of patients in the rehabilitation period after breast cancer surgery,and relieving their depression.

Background::Liver cancer remains the sixth most commonly diagnosed cancer and the third leading cause of cancer-related deaths worldwide, causing a heavy burden globally. An updated assessment of the global epidemiology of the liver cancer burden that addresses geographical disparities is necessary to better understand and promote healthcare delivery.Methods::Data were extracted from the GLOBOCAN 2022 database, including the number, crude, and age-standardized rates of incidence and mortality at the global, country, continent, and human development index (HDI) regional levels. Age-standardized rates (incidence and mortality) per 100,000 person-years were adjusted based on the Segi-Doll World standard population. The mortality-to-incidence ratios (MIR) for each region and country were calculated. The HDI and gross national income (GNI) for 2022 were obtained, and a Pearson correlation analysis was conducted with the incidence, mortality, and MIR.Results::In 2022, approximately 866,136 new liver cancer cases and 758,725 related deaths were recorded worldwide, with a global MIR of 0.86. Males had a disproportionately higher burden than females across all levels, and the highest burden was observed in the elderly population. Geographically, the regions with the highest incidence rates included Micronesia, Eastern Asia, and Northern Africa, and the regions with the highest mortality rates included Northern Africa, Southeastern Asia, Eastern Asia, and Micronesia. Notably, Mongolia had a strikingly high burden compared to other countries. The highest MIR was observed in North America and the lowest in Africa. Negative associations of HDI and GNI with liver cancer mortality and MIR were identified, irrespective of sex.Conclusions::The current liver cancer burden underscores the presence of remarkable geographic heterogeneity, which is particularly evident across countries with varying HDI levels, highlighting the urgent need to prioritize health accessibility and availability to achieve health inequities.

With the recent ongoing autumn/winter 2022 COVID-19 wave and the adjustment of public health control measures, there have been widespread SARS-CoV-2 infections in Chinese mainland. Here we have analyzed 369 viral genomes from recently diagnosed COVID-19 patients in Shanghai, identifying a large number of sublineages of the SARS-CoV-2 Omicron family. Phylogenetic analysis, coupled with contact history tracing, revealed simultaneous community transmission of two Omicron sublineages dominating the infections in some areas of China (BA.5.2 mainly in Guangzhou and Shanghai, and BF.7 mainly in Beijing) and two highly infectious sublineages recently imported from abroad (XBB and BQ.1). Publicly available data from August 31 to November 29, 2022 indicated an overall severe/critical case rate of 0.035% nationwide, while analysis of 5706 symptomatic patients treated at the Shanghai Public Health Center between September 1 and December 26, 2022 showed that 20 cases (0.35%) without comorbidities progressed into severe/critical conditions and 153 cases (2.68%) with COVID-19-exacerbated comorbidities progressed into severe/critical conditions. These observations shall alert healthcare providers to place more resources for the treatment of severe/critical cases. Furthermore, mathematical modeling predicts this autumn/winter wave might pass through major cities in China by the end of the year, whereas some middle and western provinces and rural areas would be hit by the upcoming infection wave in mid-to-late January 2023, and the duration and magnitude of upcoming outbreak could be dramatically enhanced by the extensive travels during the Spring Festival (January 21, 2023). Altogether, these preliminary data highlight the needs to allocate resources to early diagnosis and effective treatment of severe cases and the protection of vulnerable population, especially in the rural areas, to ensure the country's smooth exit from the ongoing pandemic and accelerate socio-economic recovery.

OBJECTIVE: To explore the genetic basis for a fetus with severe heart defect and mosaic trisomy 12, and the correlation between chromosomal abnormalities and clinical manifestations and pregnancy outcome. METHODS: A 33-year-old pregnant woman who presented at Lianyungang Maternal and Child Health Care Hospital on May 17, 2021 due to abnormal fetal heart development revealed by ultrasonography was selected as the study subject. Clinical data of the fetus were collected. Amniotic fluid sample of the pregnant women was collected and subjected to G-banded chromosomal karyotyping and chromosomal microarray analysis (CMA). The CNKI, WanFang and PubMed databases were searched with key words, with the retrieval period set as from June 1, 1992 to June 1, 2022. RESULTS: For the 33-year-old pregnant woman, ultrasonography at 22+6 gestational weeks had revealed abnormal fetal heart development and ectopic pulmonary vein drainage. G-banded karyotyping showed that the fetus has a karyotype of mos 47,XX,+12[1]/46,XX[73], with the mosaicism rate being 1.35%. CMA results suggested that about 18% of fetal chromosome 12 was trisomic. A newborn was delivered at 39 weeks of gestation. Follow-up confirmed severe congenital heart disease, small head circumference, low-set ears and auricular deformity. The infant had died 3 months later. The database search has retrieved 9 reports. Literature review suggested that the liveborn infants with mosaic trisomy 12 had diverse clinical manifestations depending on the affected organs, which had included congenital heart disease and/or other organs and facial dysmorphisms, resulting in adverse pregnancy outcomes. CONCLUSION Trisomy 12 mosaicism is an important factor for severe heart defects. The results of ultrasound examination have important value for evaluating the prognosis of the affected fetuses.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

Objective To investigate the application value of tenofovir alafenamide fumarate (TAF) in elderly patients with chronic hepatitis B (CHB) and its influence on bones and kidneys. Methods A total of 36 CHB patients, aged ≥60 years, who received TAF antiviral therapy in Qingdao Municipal Hospital, The Affiliated Hospital of Qingdao University, Qingdao Sixth People's Hospital, Chengyang People's Hospital, and Jimo People's Hospital from June 2021 to October 2022 were enrolled in this study, and all patients received TAF (25 mg/d) antiviral therapy. Related data were collected at baseline and weeks 24 and 48 of treatment, including virological indicators, biochemical parameters, urinary protein electrophoresis indices, transient elastography (FibroScan), and bone mineral density. Virological indicators included high-sensitivity HBV DNA quantification; biochemical parameters included total bilirubin, direct bilirubin (DBil), indirect bilirubin (IBil), alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bile acid (TBA), glucose, blood urea nitrogen, creatinine, estimated glomerular filtration rate, and cystatin C (Cys C); urinary protein electrophoresis indices included urinary β2 microglobulin (β2-MG), urinary retinol (URBP), and urinary α1 microspherin (α1-MG). The paired t -test was used for comparison of normally distributed continuous data before and after treatment, and the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment; the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 36 CHB patients completed 24 weeks of follow-up. The complete virological response rate after 24 weeks of treatment was higher than that at baseline [83.3% (30/36) vs 77.8% (28/36), χ 2 =0.36, P =0.55], and there were significant reductions in DBil ( t =-2.42, P =0.02) and Cys C ( t =-4.34, P < 0.001) from baseline to week 24. A total of 18 CHB patients completed 48 weeks of follow-up. The complete virological response rate after 48 weeks of treatment was higher than that at baseline (94.4% vs 77.8%, χ 2 =2.22, P =0.34), and there were significant increases in IBil ( t =2.43, P =0.03), TBA ( Z =-2.24, P =0.03), and bone mineral density T score of lumbar vertebra ( t =2.92, P = 0.01) and femoral neck ( t =2.42, P =0.03) and a significant reduction in liver stiffness measurement ( t =-2.31, P =0.03). There were no significant changes in β2-MG, URBP, and α1-MG after treatment (all P > 0.05). Conclusion TAF has a good antiviral effect in CHB patients aged ≥60 years and can help more CHB patients achieve complete virological response, without causing damage to the kidney, and it can also improve bone mineral density and liver fibrosis degree.
