    Abstract: More than 10 years have passed since the two best-known clinical trials of ruptured aneurysms (International Subarachnoid Aneurysm Trial [ISAT] and Barrow Ruptured Aneurysm Trial [BRAT] ) indicated that endovascular coiling (EC) was superior to surgical clipping (SC). However, in recent years, the development of surgical techniques has greatly improved; thus, it is necessary to reanalyze the impact of the differences in treatment modalities on the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). METHODS The authors retrospectively reviewed all aSAH patients admitted to their institution between January 2015 and December 2020. The functional outcomes at discharge and 90 days after discharge were assessed using the modified Rankin Scale (mRS). In-hospital complications, hospital charges, and risk factors derived from multivariate logistic regression were analyzed in the SC and EC groups after 1:1 propensity score matching (PSM). The area under the receiver operating characteristic curve was used to calculate each independent predictor’s prediction ability between treatment groups. RESULTS A total of 844 aSAH patients were included. After PSM to control for sex, aneurysm location, Hunt and Hess grade, World Federation of Neurosurgical Societies (WFNS) grade, modified Fisher Scale grade, and current smoking and alcohol abuse status, 329 patients who underwent SC were compared with 329 patients who underwent EC. Patients who underwent SC had higher incidences of unfavorable discharge and 90-day outcomes (46.5% vs 33.1%, p 〈 0.001; and 19.6% vs 13.8%, p = 0.046, respectively), delayed cerebral ischemia (DCI) (31.3% vs 20.1%, p = 0.001), intracranial infection (20.1% vs 1.2%, p 〈 0.001), anemia (42.2% vs 17.6%, p 〈 0.001), hypoproteinemia (46.2% vs 21.6%, p 〈 0.001), and pneumonia (33.4% vs 24.9%, p = 0.016); but a lower incidence of urinary tract infection (1.2% vs 5.2%, p = 0.004) and lower median hospital charges ($12,285 [IQR $10,399–$15,569] vs $23,656 [IQR $18,816–$30,025] , p 〈 0.001). A positive correlation between the number of in-hospital complications and total hospital charges was indicated in the SC (r = 0.498, p 〈 0.001) and EC (r = 0.411, p 〈 0.001) groups. The occurrence of pneumonia and DCI, WFNS grade IV or V, and age were common independent risk factors for unfavorable outcomes at discharge and 90 days after discharge in both treatment modalities. CONCLUSIONS EC shows advantages in discharge and 90-day outcomes, in-hospital complications, and the number of risk factors but increases the economic cost on patients during their hospital stay. Severe in-hospital complications such as pneumonia and DCI may have a long-lasting impact on the prognosis of patients.

    Abstract: The optimal microsurgical timing in ruptured brain arteriovenous malformations (AVMs) is not well understood and is surrounded by controversy. This study aimed to elucidate the impacts of microsurgical resection timing on clinical outcomes. METHODS The authors retrieved and reviewed the records on all ruptured AVMs treated at their institution and registered in a nationwide multicenter prospective collaboration registry between August 2011 and August 2021. Patients were dichotomized into an early resection group (≤ 30 days from the last hemorrhagic stroke) and a delayed resection group ( 〉 30 days after the last hemorrhagic stroke). Propensity score–matched analysis was used to compare long-term outcomes. The primary outcome was neurological status as assessed using the modified Rankin Scale (mRS). The secondary outcomes were complete obliteration rate, postoperative seizure, and postoperative hemorrhage. RESULTS Of the 3649 consecutive AVMs treated at the authors’ institution, a total of 558 ruptured AVMs were microsurgically resected and had long-term follow-up. After propensity score matching, 390 ruptured AVMs (195 pairs) were included in the comparison of outcomes. The mean (± standard deviation) clinical follow-up duration was 4.93 ± 2.94 years in the early resection group and 5.61 ± 2.56 years in the delayed resection group. Finally, as regards the distribution of mRS scores, short-term neurological outcomes were better in the delayed resection group (risk difference [RD] 0.3%, 95% CI −0.1% to 0.6%, p = 0.010), whereas long-term neurological outcomes were similar between the two groups (RD 0.0%, 95% CI −0.2% to 0.2%, p = 0.906). Long-term favorable neurological outcomes (early vs delayed: 90.8% vs 90.3%, p 〉 0.999; RD 0.5%, 95% CI −5.8% to 6.9%; RR 1.01, 95% CI 0.94–1.07) and long-term disability (9.2% vs 9.7%, p 〉 0.999; RD −0.5%, 95% CI −6.9% to 5.8%; RR 0.95, 95% CI 0.51–1.75) were also similar between these groups. In terms of secondary outcomes, postoperative seizure (early vs delayed: 8.7% vs 5.6%, p = 0.239; RD 3.1%, 95% CI −2.6% to 8.8%; RR 1.55, 95% CI 0.74–3.22), postoperative hemorrhage (1.0% vs 1.0%, p 〉 0.999; RD 0.0%, 95% CI −3.1% to 3.1%; RR 1.00, 95% CI 0.14–7.04), and hospitalization time (16.4 ± 8.5 vs 19.1 ± 7.9 days, p = 0.793) were similar between the two groups, whereas early resection had a lower complete obliteration rate (91.3% vs 99.0%, p = 0.001; RD −7.7%, 95% CI −12.9% to 3.1%; RR 0.92, 95% CI 0.88–0.97). CONCLUSIONS Early and delayed resection of ruptured AVMs had similar long-term neurological outcomes. Delayed resection can lead to a higher complete obliteration rate, although the risk of rerupture during the resection waiting period should be vigilantly monitored.

    Abstract: The hemodynamics of a brain arteriovenous malformation (AVM) nidus may be closely related to clinical presentation. The authors of this study aimed to explore the hemorrhagic quantitative hemodynamic indicators of the nidus through quantitative digital subtraction angiography (QDSA). METHODS The quantitative hemodynamic parameters were generated from QDSA. Three data sets were used to explore independent quantitative hemodynamic indicators associated with AVM rupture. The training data set was exploited to discover independent quantitative hemodynamic indicators of AVM rupture by performing univariate and multivariate logistic regression analyses. The authors plotted receiver operating characteristic curves to validate the diagnostic performance of the hemorrhagic hemodynamic indicators using the training and two external validation data sets. Kaplan-Meier survival analysis was adopted to verify the predictive power of these risk indicators of future hemorrhage in the external prospective validation data set. RESULTS A total of 151 patients were included in this study, 91 in the training set and 30 in each of the two validation sets. A higher stasis index and slower transnidal relative velocity (TRV) of the nidus were significantly correlated with AVM rupture. The areas under the curve (AUCs) of the stasis index (nidus) were 0.765 and 0.815 and those of the TRV (nidus) were 0.735 and 0.796, respectively, in the training and retrospective external validation sets. Kaplan-Meier survival analysis confirmed the validity of the stasis index and TRV in predicting future rupture risk in the prospective validation data set (p = 0.008 and 0.041, respectively, log-rank test). CONCLUSIONS A higher stasis index (nidus) and slower TRV (nidus) in QDSA were associated with AVM rupture and were effective indicators of future hemorrhage, suggesting that the core mechanisms underlying AVM rupture could be intravascular blood stasis and occlusive hyperemia of the nidus.

    Abstract: 9536 Background: Cancer-related fibroblasts (CAFs) are important components of the tumor microenvironment (TME) and play a key role in tumor progression. There is growing evidence that CAF levels in tumors are highly correlated with treatment response and prognosis. However, the effect of CAFs on immunotherapy response remains unknown. Methods: RNA-seq and clinical data were downloaded from TCGA and GEO. The SVA package ComBat function was used to remove batch effects. The ssGSEA algorithm was used to assess the level of cell infiltration in each sample. OS (overall survival) and DFS (disease free survival) were analyzed using the Kaplan–Meier method. GO enrichment analysis was used to assess the biological processes of subgroup differential genes. The Tumor Immune Dysfunction and Exclusion (TIDE) algorithm and subclass mapping were used to predict the clinical response to immune checkpoint blockade. Results: We evaluated the infiltration abundance of 24 types of immune cells and fibroblasts in 1768 NSCLC samples and found that almost all IMFRs (immune cells / fibroblasts) are beneficial to the prognosis. This phenomenon is called “CAFs-mediated immune resistance pattern (CMIRP)”. We evaluated the infiltration abundance of 24 types of immune cells and fibroblasts in 1768 NSCLC samples and found that almost all IMFRs (immune cells / fibroblasts) are beneficial to the prognosis. This phenomenon is called “CAFs-mediated immune resistance pattern (CMIRP)”. The prognosis according to CD8+ T cells was not strong, but CD8+ T cells / fibroblasts (CFR) were significant protective prognostic factors [n = 1588; hazard ratio (HR), 0.66; 95% confidence interval (CI), 0.56–0.78; P 〈 0.001]. Multivariate analysis revealed that the CFR was an independent prognostic biomarker. The TCGA pan-cancer cohort confirmed the widespread presence of CMIRP in cancer. We further defined the CFR high and CFR low subgroups. CFR high samples were enriched with immune activation pathways including T cell activation, cytolysis, and antigen presentation, while CFR low was associated with immunosuppression including activation of transforming growth factor β, epithelial-mesenchymal transition, and angiogenesis pathways. Finally, we combined TIDE and submap to speculate that CFR is a potential prognostic marker of immunotherapy for NSCLC. Conclusions: We proposed the term “CMIRP” to shed light on a more accurate assessment of immune status. CFR is a potential marker for prognosis and predictive efficacy of immunotherapy in NSCLC.

    Abstract: Long noncoding RNAs (lncRNAs) have emerged as diverse functional regulators involved in mammalian development; however, large-scale functional investigation of lncRNAs in mammalian spermatogenesis in vivo is lacking. Here, we delineated the global lncRNA expression landscape in mouse spermatogenesis and identified 968 germ cell signature lncRNAs. By combining bioinformatics and functional screening, we identified three functional lncRNAs ( Gm4665 , 1700027A15Rik , and 1700052I22Rik ) that directly influence spermatogenesis in vivo. Knocking down Gm4665 hampered the development of round spermatids into elongating spermatids and disrupted key spermatogenic gene expression. Mechanistically, lncRNA Gm4665 localized in the nucleus of round spermatids and occupied the genomic regulatory region of important spermatogenic genes including Ip6k1 and Akap3 . These findings provide a valuable resource and framework for future functional analysis of lncRNAs in spermatogenesis and their potential roles in other biological processes.

    Abstract: Oxidative stress plays crucial roles in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). Thioredoxin-interacting protein (TXNIP) is essential in the process of triggering oxidative stress. However, its role and mechanism in CRSwNP remain unclear. The present study sought to explore the role and mechanism of TXNIP in the pathogenesis of CRSwNP. Methods Western blotting, real-time PCR and immunohistochemistry (IHC) were employed to assess TXNIP, thioredoxin (TRX) expression in nasal tissue samples from patients with CRSwNP and control subjects. MDA level and SOD activity in nasal tissue homogenates were measured using MDA and SOD Assay Kit. To evaluate the role and mechanism of TXNIP in CRSwNP, human nasal epithelial cells (HNECs) were cultured and stimulated using TXNIP siRNA, with or without N-acetylcysteine (NAC, an ROS scavenger). Western blotting, real-time PCR, ROS detecting dye DCFH-DA, MDA and SOD Assay Kit were performed to assess the effects and mechanisms of stimulators on the cells. Results We found significantly increased levels of TXNIP and decreased levels of TRX protein, mRNA, positive cells, increased MDA level and decreased SOD activity in CRSwNP patients compared with control subjects. In vitro study, significantly altered levels of TXNIP, TRX, MDA, SOD and ROS in HNECs were found following treatment of TXNIP siRNA with or without NAC on HNECs. Conclusion TXNIP expression was increased and TRX expression was decreased in CRSwNP at both protein and mRNA levels. MDA levels were increased and SOD activities were decreased in CRSwNP. TXNIP may have negative association with TRX, and then decrease SOD activities and increase MDA levels, resulting in the upregulation of ROS and oxidative stress in HNECs, which may play a pivotal role in the pathogenesis of CRSwNP. Future studies are expected to further explore the role and mechanism of TXNIP in CRSwNP.
