The median number of Flaer-negative white blood cells was 94.0% (13.0% - 99.9%) ; the median CD59 negative red blood cells was 46.7% (9.0% - 93.0%). The deposition of C5b-9, C3, C4b, and FB on red blood cells, white blood cells, and platelets in patients with PNH was significantly higher than that in NC (all <i>P</i><0.05). C5b-9 deposition level was significantly higher than that of C3, C4b, and FB on all three blood cell lineages in PNH patients (all <i>P</i><0.01). The deposition of all complement fragments on red blood cells was significantly lower than that on white blood cells and platelets (all <i>P</i><0.01). C5b-9 deposition on red blood cells was positively correlated with Ret in PNH patients (<i>P</i>=0.005). C3 (<i>P</i>=0.001) and C4b (<i>P</i>=0.017) deposition levels on white blood cells and C3 deposition on platelets (<i>P</i>=0.002) in patients with TEE history were lower than those without. <b>Conclusions:</b> C5b-9, C3, C4b, and FB deposition levels on all three blood cells in patients with PNH were higher than NC. Increased C5b-9 on red blood cells may indicate active hemolysis. Reduced C3 and C4b levels on white blood cells and low C3 deposition on platelets may indicate TEE risk.</p>","PeriodicalId":24016,"journal":{"name":"Zhonghua xue ye xue za zhi = Zhonghua xueyexue zazhi","volume":"46 4","pages":"314-320"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12158814/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144162633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some patients still face relapse or refractory issues, as well as the risk of death due to treatment-related adverse reaction. Treatment has fully entered the era of targeted therapy in recent years, with the deepening research on cHL. Novel drugs, represented by targeted CD30 antibody-drug conjugates and immune checkpoint inhibitors, have further improved the prognosis of patients with newly diagnosed and relapsed/refractory cHL. This study aims to determine the mechanism of achieving comprehensive optimization management of cHL in the new era of drugs, improve patient prognosis, enhance therapeutic efficacy, and reduce the occurence of adverse reactions.</p>","PeriodicalId":24016,"journal":{"name":"Zhonghua xue ye xue za zhi = Zhonghua xueyexue zazhi","volume":"46 4","pages":"364-371"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12158810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
