Endovascular thrombectomy for acute large-vessel occlusion in patients with active cancer remains a difficult clinical decision. Multiple cohort studies and meta-analyses indicate that, when standard imaging and clinical criteria are applied, reperfusion success is high and symptomatic intracranial hemorrhage is broadly comparable with non-cancer populations, arguing against categorical exclusion. At the same time, registries show lower 90-day functional independence and higher 90-day mortality in active-cancer cohorts—effects likely driven by malignancy-related systemic factors and pre-existing functional compromise rather than procedural harm. This narrative review synthesizes efficacy and safety signals, highlights decision-grade outcomes that are seldom reported—early neurological change, performance status around 90 days, and whether systemic anticancer therapy is started or resumed. It sets out a clinical–ethical–economic framework to support selection, consent, and aftercare, including a pragmatic pathway for under-resourced settings based on non-contrast computed tomography (CT) or single-phase CT angiography where advanced perfusion imaging or magnetic resonance imaging are unavailable. We outline an Asia–Pacific collaborative program designed to identify subgroups that may benefit from reperfusion and initiation of active cancer care.

Objective:To construct a triple pre-rehabilitation intervention program for patients undergoing radical prostatectomy, to provide a basis for promoting pre-rehabilitation in patients undergoing radical prostatectomy.Methods:Literature analysis was used to search domestic and foreign databases such as China National Knowledge Infrastructure, Wanfang, PubMed, etc, on triple pre-rehabilitation and rapid rehabilitation of patients undergoing radical prostatectomy, with a search time frame from January 1, 2013 to December 31, 2023. The Delphi expert letter consultation was conducted later, and the final draft of the triple pre-rehabilitation intervention program for patients with radical prostatectomy was finally formed.Results:A total of 20 experts completed 2 rounds of inquiries, all were female, with an age of (40.85 ± 5.40) years old. The response rates for the 2 rounds of expert inquiries were both 100%(20/20). The authority coefficients of the experts were 0.87 and 0.90, respectively. Kendall coordination coefficients were 0.11 and 0.21, respectively. The coefficient of variation for each item in the second round of inquiries ranged from 0 to 0.15. The triple pre-rehabilitation intervention program for patients with radical resection of prostate cancer was constructed, including 4 primary indexes, 8 secondary indexes and 25 tertiary indexes.Conclusions:It is scientific, targeted and feasible to construct a triple pre-rehabilitation intervention program for patients undergoing radical prostatectomy based on Delphi method, which can provide clinical basis for pre-rehabilitation of elderly patients undergoing prostate cancer surgery.

Objective To explore the preventive and therapeutic effects of quercetin(QU)loaded with different nanomate-rials on high altitude cerebral edema(HACE)in rats and their mechanisms.Methods Thirty male SD rats were selected and equally divided into a normoxic group,a HACE group,a HACE+QU group,a HACE+carbon quantum dots(CQDs)-loaded QU(QU@CQDs)group,a HACE+mesoporous silica(MS)-loaded QU(QU@MS)group and a HACE+zeolitic imida-zolate framework-8(ZIF-8)loaded QU(QU@ZIF-8)group.The rats except those in the normoxic group were exposed to a simulated 5 000 m altitude in a low-pressure oxygen chamber,which were orally administered QU at a dose of 5 mg/g body mass 1 h before hypoxic exposure except those in the HACE group.The groups were compared in terms of the effects of the materials on the water content of rat brain tissue,cerebrovascular leakage,hematological changes and NF-κB-related mechanisms.Statistical analysis was performed using SPSS 26.0 software.Results When compared with the rats in the normoxic group,the ones in the HACE group showed significant increases in brain tissue water content,cerebrovascular leakage,leukocytes,erythrocytes,lymphocytes,monocytes,granulocytes,mean erythrocyte volume,hemoglobin,hematocrit,platelets,reactive oxygen species and malondialdehyde and NF-κB protein levels,with obvious oxidative damage and statistically decreased oxidative stress parameters including glutathione peroxidase,glutathione and superoxide dismutase(all P＜0.05).When compared with the HACE+QU@CQDs and HACE+QU@MS groups,the HACE+QU@ZIF-8 group gained advantages with the lowest brain tissue water content,improved cerebrovascular leakage,leukocytes,erythrocytes,lymphocytes,monocytes,granulocytes,mean erythrocyte volume,hematocrit,platelets and hemoglobin,decreased oxidative damagea and oxidative stress,enhanced antioxidant enzyme levels and the statistically lowered NF-κB protein level.Conclusion ZIF-8 loaded QU behaves better than CQDs and MS in reducing inflammation and brain edema formation in HACE rats.[Chinese Medical Equipment Journal,2025,46(5):27-33]

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

Objective:To clarify the prognostic significance of 1q21 amplification in multiple myeloma(MM),and explore the efficacy and prognosis of ixazomib in the treatment of MM patients with 1q21 amplification.Methods:A retrospective analysis of clinical data was conducted on 77 patients with newly diagnosed MM who were hospitalized in Zhongshan Hospital,Xiamen University from January 2010 to December 2022.To analyze the clinical features of MM patients with 1q21 amplification,evaluate the mitigation rate and survival treated with ixazomib-based regimens.Results:Among the 77 newly diagnosed MM patients,40 patients had 1q21 amplification,while 37 didn't.Multivariate Cox regression analysis revealed that 1q21 amplification was an independent risk factor affecting the prognosis of MM patients(P＜0.05).Compared to patients without 1q21 amplification,those with 1q21 amplification had poorer progression-free survival(PFS)and overall survival(OS)(both P＜0.05).When the 1q21 amplification ratio exceeded 66.7％,both PFS and OS were worse(P＜0.05).There were no statistical differences in the deep remission rate(≥VGPR),overall response rate and PFS between the 1 q21 amplification positive and negative groups treated with ixazomib-based regimens(P＞0.05),but OS showed a significant difference(P＜0.05).Among the patients who switched to ixazomib treatment from bortezomib,there was a statistically significant difference in the complete response rate(P＜0.05).Compared to other treatment regimens,ixazomib-based regimens resulted in a significant reduction in adverse reactions such as peripheral neuropathy(P＜0.05).Conclusion:Ixazomib-based chemotherapy regimens can overcome the poor prognosis associated with 1q21 amplification and improve mitigation rates and PFS in patients.Ixazomib has low incidence of adverse reactions,good safety profile and prolonged duration of therapy.

Objective:To analyze the proportion of nonobstructive azoospermia(NOA)patients opting for sperm bank donation under different sperm retrieval methods[percutaneous testicular sperm aspiration(TESA),microdissection testicular sperm extraction(mTESE)]and its influencing factors.Methods:Retrospective data from assisted reproductive technology(ART)cycles at the Center for Reproductive Medical,Peking University Third Hospital(from January 2019 to December 2023)were collected.Data-complete ART cycles involving NOA patients and their partners(using the last treatment cycle as the endpoint)were selected.Sperm donation utilization rates were compared across retrieval methods(fresh mTESE,fresh TESA,thawed mTESE,thawed TESA).Log-linear models were used to analyze the rela-tionship between sperm retrieval method and sperm source.Results:Among the 1 730 couples,the over-all sperm donation utilization rate was 12.66％.The highest rate occurred in the fresh mTESE group(23.42％),followed by the thawed mTESE group(5.87％).The rates for the fresh TESA and thawed TESA groups were 5.22％and 0％,respectively.Log-linear analysis demonstrated that sperm retrieval method was significantly associated with sperm source(mTESE:Estimate=4.499;TESA:Estimate=2.780;P＜0.001).Conclusion:The low overall sperm donation utilization rate in ART cycles may re-flect the efficacy of synchronous sperm retrieval ART.The proportion of NOA patients opting for sperm donation was influenced by the retrieval method.Compared with patients undergoing TESA,those under-going mTESE were more inclined to utilize donor sperm after retrieval failure.

Oncological microdissection testicular sperm extraction (onco-micro-TESE) represents a significant breakthrough for patients with nonobstructive azoospermia (NOA) and a concomitant in situ testicular tumor, to be managed at the time of sperm retrieval. Onco-micro-TESE addresses the dual objectives of treating both infertility and the testicular tumor simultaneously. The technique is intricate, necessitating a comprehensive understanding of testicular anatomy, physiology, tumor biology, and advanced microsurgical methods. It aims to carefully extract viable spermatozoa while minimizing the risk of tumor dissemination. This review encapsulates the procedural intricacies, evaluates success determinants, including tumor pathology and spermatogenic tissue health, and discusses the implementation of imaging techniques for enhanced surgical precision. Ethical considerations are paramount, as the procedure implicates complex decision-making that weighs the potential oncological risks against the profound desire for fatherhood using the male gametes. The review aims to provide a holistic overview of onco-micro-TESE, detailing methodological advances, clinical outcomes, and the ethical landscape, thus offering an indispensable resource for clinicians navigating this multifaceted clinical scenario.

OBJECTIVE: To determine the carrier rate for thalassemia mutations in the ethnic Miao population of Qianxinan Prefecture. METHODS: Ethnic Miao people suspected for thalassemia trait at the People's Hospital of Qianxinan Prefecture, Guizhou Province between November 2020 to September 2024 were selected as the study subjects. Gap-PCR technology combined with high-throughput sequencing was used to screen a total of 666 individuals. ArcMap v10.8.2 was used to create a spatial distribution map of thalassemia based on the screening results. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2016-01). RESULTS: In total 254 positive cases were detected, with an overall positive rate of 38.14%. Among these, 173 cases were α-thalassemia (25.98%), 77 cases were β-thalassemia (11.56%), and 4 cases were αβ compound thalassemia (0.60%). The most common genotypes for α-thalassemia were αα/--^SEA (positive rate = 10.06%, accounting for 38.73%), αα/-α^3.7 (positive rate = 8.86%, accounting for 34.10%), and α^CSα/αα (positive rate = 4.95%, accounting for 19.08%). The most common genotypes for β-thalassemia were β^41/42(-TTCT)/β^A (positive rate = 5.11%, accounting for 44.16%) and β^{17 (A>T)}/β^A(positive rate = 4.20%, accounting for 36.36%), with these two genotypes accounting for as much as 80.52%. The spatial distribution map indicated that the highest overall detection rate of thalassemia and α-thalassemia in the Miao population of Qianxinan Prefecture was in Xingyi City. The highest detection rate of β-thalassemia was in Zhenfeng County, and the highest detection rate of αβ compound thalassemia was in Wangmo County. CONCLUSION The detection rate of thalassemia among the ethnic Miaos from Qianxinan Prefecture is relatively high, which primarily consisted of α-thalassemia. Regular monitoring and educational outreach should be conducted.
