Objective:To investigate the predictive value of microRNA-1(miR-1),brain natriuretic peptide(BNP)and ischemia-modified albumin(IMA)for unstable angina pectoris(UAP).Methods:We enrolled 237 UAP patients admitted to Xining Second People's Hospital between June 2018 and December 2020 as UAP group.Another 86 healthy subjects undergoing physical examination simultaneously were enrolled as control group.MiR-1 expression,BNP and IMA levels were measured.General data between UAP group and control group,serum miR-1 expression,BNP and IMA levels among different Braunwald class and prognosis were compared.Receiver operat-ing characteristic(ROC)curve was employed to analyze predictive value of miR-1,BNP,IMA and their combina-tion for prognosis in UAP patients.Results:Compared with participants in the control group,those in UAP group had significant higher serum miR-1 expression[(1.80±0.59)vs.(0.93±0.11)],BNP[(107.34±37.46)pg/ml vs.(52.31±10.64)pg/ml]and IMA[(79.76±19.29)g/L vs.(53.16±6.43)g/L](P＜0.001 all).As Braun-wald class increased(class Ⅰ～Ⅲ),serum miR-1 expression,BNP and IMA levels elevated(P＜0.001 all).Com-pared with patients in favorable outcome group,those in unfavorable outcome group had significant higher serum miR-1 expression[(2.31±0.54)vs.(1.53±0.41)],BNP[(147.03±29.63)pg/ml vs.(85.95±19.46)pg/ml]and IMA[(97.24±15.35)g/L vs.(70.35±13.88)g/L](P＜0.001 all).ROC curve indicated that AUC of com-bined detection for predicting unfavorable outcome in UAP patients was 0.925(95％CI 0.884～0.955),which was significantly higher than miR-1(AUC=0.880,95％CI 0.831～0.918),BNP(AUC=0.863,95％CI 0.813～0.904)and IMA(AUC=0.900,95％CI 0.854～0.935)alone(Z=2.884,3.130,2.090,P＜0.05 or＜0.01).Conclusion:MiR-1 expression,BNP and IMA levels significantly increase in UAP patients,and they are associated with the severity of disease.Combined detection has good predictive value for unfavorable outcome in UAP pa-tients.

OBJECTIVE: To explore and evaluate the efficacy and safety of a modified thiotepa-based conditioning regimen combined with autologous hematopoietic stem cell transplantation (ASCT) for the treatment of primary central nervous system lymphoma (PCNSL). METHODS: In a retrospective, single center, single arm study, we collected data of 28 patients with PCNSL who underwent high-dose chemotherapy followed by autologous stem cell transplantation (HDC-ASCT) at our center from March 2021 to December 2024. The clinical characteristics of the patients, the conditioning regimen details, treatment-related toxicities and adverse reactions, post-transplant disease remission status, and survival outcomes were analyzed. RESULTS: A total of 28 patients were included. Among them, 19 patients received ASCT as first-line consolidation therapy in complete response (CR) or partial response (PR) status, and 9 patients with relapsed/refractory disease underwent salvage ASCT. The median time to neutrophil engraftment was 9 days (range: 5-11 days), and the median time to platelet engraftment was 10 days (range: 6-13 days). All patients achieved CR at the initial efficacy evaluation post-ASCT. The main complications during the transplantation period were febrile neutropenia (26 cases) and grade 3 diarrhea (9 cases). No transplantation-related mortality occurred. Post-ASCT, 19 patients received maintenance therapy, which was demonstrated to be safe and effective. Three patients relapse, and one patient died. The median progression-free survival (PFS) and overall survival (OS) of patients were not reached. The estimated 1-year and 2-year cumulative PFS rates were 88.4% and 66.3%, respectively, while the 1-year and 2-year OS rates were both 94.1%. CONCLUSION The modified thiotepa-based conditioning regimen combined with ASCT is safe and effective for the treatment of PCNSL.

【Objective】 To explore the risk factors for the production of anti-HLA antibodies in patients with hematological diseases before hematopoietic stemcell transplantation. 【Methods】 The results and clinical data of 1 008 patients with hematological diseases in our hospital who underwent anti-HLA antibody testing were collected by using Luminex technology platform before transplantation from 2016 to 2018 for statistical analysis. 【Results】 The total positive rate of anti-HLA antibodies in 1 008 patients was 24.08%. Multivariate analysis showed that independent risk factors associated with the production of anti-HLA antibodies included age≥30 years old(P=0.046, OR1.467, 95%CI1.007-2.136), time from disease diagnosis to antibody testing≥41 days(P=0.000, OR1.830, 95%CI1.306-2.565), initial platelet count<20×10⁹/L(P=0.020, OR1.543, 95%CI1.072-2.220), prior pregnancy(P=0.000, OR5.187, 95%CI3.689-7.293), transfusions before admission(P=0.001, OR1.762, 95%CI1.257-2.470)and total platelet transfusion volumes after admission≥30 U(P=0.000, OR2.352, 95%CI1.638-3.376). Age ≥30 years old(P=0.023, OR=1.839, 95%CI1.088-3.108)and prior pregnancy(P=0.042, OR=5.258, 95%CI1.062-26.038)are associated with the production of anti-HLA class Ⅰ and class Ⅱ antibodies, respectively. The time from disease diagnosis to antibody testing≥41 days(P=0.000, OR=2.873, 95%CI1.612-5.119), initial platelet count<20×10⁹/L(P=0.008, OR=2.164, 95%CI1.225-3.822), prior pregnancy(P=0.002, OR=6.734, 95%CI1.993-22.751), transfusions before admission(P=0.001, OR=2.746, 95%CI1.531-4.925)and total platelet transfusion volumes after admission>30 U(P=0.006, OR=3.459, 95%CI1.416-8.451)are associated with the production of anti-HLA class Ⅰ and Ⅱ antibodies. 【Conclusion】 Older age, longer course of disease, lower PLT count, history of pregnancy and blood transfusion, and higher total amount of PLT transfusion are risk factors which affect the production of anti-HLA antibodies.Therefore, it is advisable to test for anti-HLA antibodies according to the situation before transplantation, which is of great value in guiding donor selection, monitoring antibody changes and improving transplant prognosis.

Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age. Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively. Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk. Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.

Objective To explore the incidence of long CO VID symptoms in patients infected with Omicron variant of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Methods According to the inclusion and exclu-sion criteria of literatures,relevant studies without language restrictions published up to 2024 were retrieved from both Chinese and English databases.The Chinese databases were China National Knowledge Infrastructure(CNKI),Wanfang Database,and VIP databases,and the foreign databases were PubMed,Embase,and Web of Science.Three-step screening was used to select literatures,and Stata 17.0 software was used for analysis.Results The incidence of at least one sequelae in patients infected with Omicron variant was 29.62％.The most common symptoms included fatigue(19.10％),joint or muscle pain(11.06％),memory loss(9.71％),brain fog(8.80％),cough(8.42％),headache(7.26％),and sore throat(6.68％).Subgroup analysis results showed that with the extension of follow-up(3 months vs 6 months),the incidence of smell or taste changes was significantly re-duced(7.22％vs 0.78％).The higher the proportion of women(＜50％vs 50％-65％vs＞65％),the higher the incidence of joint or muscle pain(1.09％vs 4.62％vs 19.53％);the greater the median age(≥45 years vs＜45 years),the higher the incidence of chest pain or chest distress(0.90％vs 3.86％),all with statistically significant differences(all P＜0.05).Conclusion Incidence of long COVID in Omicron-infected patients is high and can cause various symptoms.Follow-up time,median age and gender proportion have significant impacts on the incidence of some symptoms.
