Blood transfusion is an important life-support measure in modern medicine. As clinical demand for transfusion continues to rise, blood supply remains under persistent strain, making the efficient utilization of this precious medical resource a critical component of blood management. Accurate prediction of transfusion needs is of great significance for optimizing blood resource allocation and conserving blood products. Traditional transfusion decision-making relies on clinical experience and simplified scoring systems, which are insufficient to meet the demands of precision medicine. Machine learning (ML) technology can integrate multidimensional data—including demographic characteristics, laboratory indicators, surgical information, and dynamic physiological waveforms—to construct high-performance predictive models, offering a new approach to transfusion prediction. This article systematically reviews the application progress of ML in transfusion prediction across clinical scenarios such as trauma, the perioperative period, and obstetrics. In trauma, ML has been applied to early massive transfusion prediction, prehospital transfusion decision-making, and precise prediction in pediatric trauma. In the perioperative field, applications span specialties including traumatic brain injury, orthopedic surgery, cardiovascular and major vascular surgery, and hepatic surgery. In obstetrics, models can effectively predict postpartum hemorrhage and transfusion requirements associated with cesarean section. Studies have shown that algorithms such as random forest, gradient boosting machines, and deep neural networks achieve area under the receiver operating characteristic curve (AUC) values of 0.83-0.98 in massive transfusion prediction, 0.75-0.97 in perioperative scenarios, and 0.80-0.89 in obstetric transfusion prediction—significantly outperforming traditional scoring tools. However, current studies are generally limited by single-center retrospective designs, insufficient external validation, and inadequate reporting standards; limited model interpretability and challenges in clinical integration further constrain practical translation. Future research should focus on constructing multicenter data cohorts, integrating multimodal data, conducting prospective implementation studies, and deeply embedding models within electronic health record systems, thereby advancing the application of ML to optimize clinical transfusion decision-making.

Objective:To discuss the effect of acupuncture on the differentiation and apoptosis of quadriceps muscle satellite cells in model rats with knee osteoarthritis(KOA),and to clarify its related mechanism.Methods:A total of 40 SPF-grade rats were selected and randomly divided into control group,model group,celecoxib group,and acupuncture group,with 10 rats in each group.The rats in control group only underwent joint cavity incision followed by suturing,while the rats in model group,celecoxib group,and acupuncture group were used to replicate the KOA models.The maximum circumference of the femoral segment of the affected limb,rat body mass,and quadriceps wet weight of the rats in various groups were measured;the quadriceps wet weight maintenance rate and quadriceps wet weight/body

proteins in quadriceps muscle tissue of the rats in model group were significantly decreased(P<0.05);compared with model group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05);compared with celecoxib group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05).Compared with control group,the expression levels of B-cell lymphoma 2(Bcl-2),B-cell lymphoma-xl(Bcl-xl),and myeloid cell leukemia 1(MCL1)proteins in quadriceps muscle tissue in model group were significantly decreased(P<0.05),and the

quadriceps muscle satellite cells and inhibit muscle cell apoptosis in the model rats with KOA,and the mechanism may be related to the up-regulation of expressions of IL-6,JAK,and STAT3 proteins in the quadriceps muscle tissue.

As a crucial barrier to ensuring blood transfusion safety, blood virus inactivation technology plays an irreplaceable role in addressing the "window period" of detection, the threat of emerging pathogens, and the limitations of detection technologies. This article systematically reviews the current status and technical characteristics of mainstream blood virus inactivation technologies, and conducts an in-depth discussion on the application prospects and challenges of emerging technologies in this field. Among conventional technologies, the photochemical methods (including methylene blue, psoralen S-59/INTERCEPT system, and riboflavin/Mirasol system) have been widely used in clinical practice due to their broad-spectrum inactivation capacity. However, these methods are associated with functional impairment of blood components. The organic solvent/detergent (S/D) method performs excellently in inactivating viruses in plasma products yet is ineffective against non-lipid-enveloped viruses. Short-wave ultraviolet (UVC) direct irradiation technology eliminates the need for chemical additives, though its inactivation efficiency and compatibility with blood components requires optimization. The chemical modification method, while specifically designed for red blood cells, faces safety challenges such as potential immunogenicity. For emerging technologies, cold plasma technology shows great potential owing to its multi-target synergistic inactivation mechanism, though challenges regarding its biocompatibility and selectivity remain. Electrolyzed water technology has the advantages of low cost and operational simplicity, yet in-depth research is needed on the non-specific damage caused by active substances to blood components. Novel photodynamic therapy significantly improves inactivation efficiency by developing high-efficiency targeted photosensitizers and has broad prospects for combined applications with antibodies, nanomaterials, and other substances. Future development trends point to the "combination therapy" strategy, which leverages the synergy of multiple technologies to achieve the optimal balance between efficient virus inactivation and functional prservation of blood components. The development of such technologies needs to shift from "single-method" to "integrated approach", from "inactivation" to "viability preservation", and bridge the translation gap from "laboratory" to "global application". The ultimate goal is to establish a standardized, automated, and cost-controllable comprehensive blood safety assurance system.

Objective To investigate the expression and clinical significance of CD155 in oral squamous cell carci-noma(OSCC)tissues,as well as its impact on migration,proliferation and invasion.Methods Immunohisto-chemistry(IHC)was used to analyze the expression of CD155 in OSCC tissues and its correlation with clinicopath-ological features and prognosis.The transcription levels of CD155 were assessed by Western blot and RT-qPCR.Cell experiments were conducted to evaluate the effects of CD155 on OSCC cells following transfection with CD155 siRNA.Results CD155 was predominantly expressed on the cell membrane in OSCC tissues,with higher expres-sion levels compared to normal tissues(x2=50.750,P＜0.000 1).High CD155 expression was associated withⅢ+Ⅳ disease stages(x2=25.488,P=0.001),poor differentiation(x2=6.299,P=0.012),T3+T4 depth of invasion(x2=23.820,P=0.001)and lymph node metastasis(x2=7.830,P=0.005)in OSCC patients;survival analysis revealed a correlation between high CD155 expression and shorter patient survival(P＜0.05).COX regression analysis identified lymph node metastasis as an independent factor affecting the survival of OSCC patients(P＜0.05).Both CD155 protein expression and mRNA transcription levels were significantly upregulated in OSCC cells(P＜0.05).Transfection with siRNA-CD155 in OSCC cells resulted in significantly reduced prolif-eration,migration and invasion abilities compared to the control group(P＜0.05).Conclusion CD 155 is highly expressed in OSCC tissues and is associated with poor patient prognosis.Modulating CD155 expression can influ-ence the biological functions of OSCC cells,leading to and inhibition of proliferation,migration,and invasion.

The concept of holographic law is widely reflected in the theory and clinical practice of traditional Chinese medicine （TCM）. From philosophical perspective， TCM encompasses rich holographic law concepts， such as the theory of qi as the fundamental essence， mutual rooting and mutual storage of yin and yang， and mutual storage and classifications of the five phases. Through philosophical exploration of holographic law in TCM， this paper aimed to elucidate the connection between holographic law and TCM， and analyze the value and limitations of holographic law in TCM. Future research on holographic law in TCM should not only philosophically scrutinize the relationship between the whole and its parts under the guidance of holographic law thinking， but also incorporate qualitative and quantitative studies by referring to modern disciplines such as anatomy， physiology， and pathology， in order to better understand and validate the holographic law concepts in TCM.

Objective:To investigate the correlation between clinical phenotypes and genetic characteristics of children with ring chromosomes (RCs).Methods:Case series study.The clinical data of 11 434 children who received treatment and peripheral blood chromosome karyotype detection in Henan Children′s Hospital from October 2008 to October 2023 due to growth retardation, intellectual impairment or congenital malformation were analyzed retrospectively.A total of 25 children with RCs were selected.Their age at diagnosis, karyotype distribution, clinical manifestations, and genetic detection results were analyzed.Results:RCs were detected in 25 out of 11 434 children, with a detection rate of 0.21%.The genome-wide copy number variation (CNV) analysis was performed on 7 RCs cases, and it found that pathogenic variation existed in all of them.Among the 25 RC cases (11 males and 14 females of social gender), the age at diagnosis ranged from 2 months to 14 years; there were 20 autosomal rings and 5 sex chromosome rings; 13 cases had chimeric karyotypes, and 12 cases had non-chimeric karyotypes.Most of the 25 children showed clinical manifestations of mental or developmental retardation, and some also presented with specific clinical manifestations, such as short stature, congenital malformation, and epilepsy.Conclusions:The pathogenesis of RCs is complex.The clinical manifestations are determined by both RCs syndrome and specific phenotypes caused by the dose effect and exhibit high heterogeneity, so it is easy to miss or misdiagnose.The combined application of cellular and molecular genetic detection technology can facilitate early diagnosis and treatment of RCs, and the correlation analysis of phenotypes and genetic characteristics can provide guidance for genetic counseling.
