AIM: To study the relationship between anti-β2- glycoprotein Ⅰ (aβ2GPⅠ) antibodies and platelet activation state in patients with ulcerative colitis (UC) and its significance. METHODS: Peripheral blood samples were collected from 56 UC patients (34 males and 22 females, aged 43.5 years, range 21-66 years), including 36 at active stage and 20 at remission stage, and 25 sex-and age-matched controls. The level of aβ2GP Ⅰ was measured by ELISA. The platelet activation markers, platelet activation complex- Ⅰ (PAC- Ⅰ ) and P-selectin (CD62P) were detected by flow cytometry. RESULTS: The A value for IgG aβ2GP Ⅰ in the active UC group was 0.61 ± 0.13, significantly higher than that in the remittent UC and control groups (0.50 ± 0.13 and 0.22 ± 0.14, P 〈 0.01). There was a significant difference between the two groups (P 〈 0.01). The A value for IgM aβ2GP Ⅰ in the active and remittent UC groups was 0.43 ± 0.13 and 0.38 ± 0.12, significantly higher than that in the control group (0.20 ± 0.12, P 〈 0.01). However, there was no significant difference between the two groups (P 〉 0.05). The PAC- Ⅰ positive rate for the active and remittent UC groups was 30.6% ± 7.6% and 19.6% ± 7.8% respectively, significantly higher than that for the control group (6.3% ± 1.7%,P 〈 0.01). There was a significant difference between the two groups (P 〈 0.01). The CD62P positive rate for the active and remittent UC groups was 45.0% ± 8.8% and 31.9% ± 7.8% respectively, significantly higher than that for the control group (9.2% ± 2.7%, P 〈 0.01). There was a significant difference between the two groups (P 〈 0.01). In the active UC group, the more severe the state of illness was, the higher the A value for IgG aβ2GP Ⅰ was, and the positive rate for PAC-Ⅰ and CD62P was positively correlated with the state of illness (Faβ2GP Ⅰ = 3.679, P 〈 0.05; FPAC-Ⅰ (%) = 5.346, P 〈 0.01; and FCD62P (%) = 5. 418, P 〈 0.01). Meanwhile, in the same state of illness, the A value for IgG aβ2GP Ⅰ was positively correlated to the positive rates for PAC-Ⅰ and CD62P. CONCLUSION: aβ2GP Ⅰ level, platelet activation state and their relationship of them are closely correlated with the pathogenesis and development of UC. 展开更多

Treatment of hepatocellular carcinoma(HCC)in the caudate lobe is technically challenging.This retrospective study was designed to evaluate the clinical outcome of both superselective transcatheter arterial chemoembolization(TACE)and liver resection(LR)for HCC occurring exclusively in the caudate lobe.From January 2008 to September 2021,a total of 129 patients were diagnosed with HCC of the caudate lobe.The Cox proportional hazard model was used to analyze the potential clinical factors and established prognostic nomograms with interval validation.Of the total number of patients,78 received TACE and 51 received LR.The overall survival(OS)rates(TACE vs.LR)at 1,2,3,4,and 5 years were 83.9%vs.71.0%;74.2%vs.61.3%;58.1%vs.48.4%;45.2%vs.45.2%;and 32.3%vs.25.0%,respectively.However,subgroup analysis revealed that TACE was superior to LR for treating patients with stage IIb Chinese liver cancer(CNLC-IIb)in the entire cohort(p=0.002).Interestingly,no difference was found between TACE and LR in the treatment outcomes of CNLC-IIa HCC(p=0.6).Based on Child-Pugh A and B calculations,TACE tended to lead to a better OS than LR(p=0.081 and 0.16,respectively).Multivariate analysis showed that Child-Pugh score,CNLC stage,ascites,alpha fetoprotein(AFP),tumor size,and anti-HCV are related to OS.Predictive nomograms for 1,2,and 3 years were performed.Based on this study,TACE may provide a longer OS than liver resection for patients with CNLC-IIb HCC of the caudate lobe.Because this suggestion is limited by the study design and relatively small sample size,additional randomized controlled trials are needed. 展开更多
