Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Liver metastases (LMs) are common in lung cancer. Despite substantial advances in diagnosis and treatment, the survival rate of patients with LM remains low as the immune-suppressive microenvironment of the liver allows tumor cells to evade the immune system. The impact of LMs on the outcomes of immune checkpoint inhibitors in patients with solid tumors has been the main focus of recent translational and clinical research. Growing evidence indicates that the hepatic microenvironment delivers paracrine and autocrine signals from non-parenchymal and parenchymal cells. Overall, these microenvironments create pre- and post-metastatic conditions for the progression of LMs. Herein, we reviewed the epidemiology, physiology, pathology and immunology, of LMs associated with non-small cell lung cancer and the role and potential targets of the liver microenvironment in LM in each phase of metastasis. Additionally, we reviewed the current treatment strategies and challenges that should be overcome in preclinical and clinical investigations. These approaches target liver elements as the basis for future clinical trials, including combinatorial interventions reported to resolve hepatic immune suppression, such as immunotherapy plus chemotherapy, immunotherapy plus radiotherapy, immunotherapy plus anti-angiogenesis therapy, and surgical resection.

[摘 要] 目的：探讨α-常春藤皂苷（α-Hed）诱导非小细胞肺癌（NSCLC）细胞凋亡的作用靶点及其潜在机制，明确α-Hed与顺铂（DDP）联用后对相应的靶点蛋白表达的影响。方法：采用CCK-8法检测不同浓度α-Hed处理后NSCLC细胞A549、H1299和PC-9的存活率，采用Annexin Ⅴ-FITC/PI染色流式细胞术检测细胞凋亡率，采用WB法检测细胞中C-caspase-3和Bcl-2蛋白的表达。通过网络药理学相关方法筛选α-Hed的潜在靶点，利用分子对接法分析其结合效果，WB法检测靶点蛋白的表达。通过CCK-8法、细胞集落形成实验和WB法检测α-Hed与DDP联用对NSCLC细胞的抑制作用。结果：给药24和48 h后，10、15和20 μmol/L α-Hed可以显著抑制NSCLC细胞增殖活力（均P<0.01）；与对照组相比，20 μmol/L α-Hed处理后细胞凋亡率显著升高（P<0.01）；α-Hed可上调NSCLC细胞中C-caspase-3的表达（P<0.05），下调Bcl-2的表达（P<0.05）。网络药理学和分子对接筛选出结合亲和力小于-5 kcal/mol的靶点AKT1、STAT3、EGFR和JAK2。WB法检测结果显示，α-Hed处理后A549、H1299细胞中EGFR、p-AKT/AKT、p-STAT3/STAT3和JAK2蛋白的表达均明显下调（均P<0.05）。α-Hed与DDP联用后，更显著地抑制NSCLC细胞的增殖（P<0.01），进一步下调EGFR、p-AKT/AKT、p-STAT3/STAT3和JAK2蛋白的表达（P<0.05或P<0.01）。结论：α-Hed通过下调EGFR和JAK2的表达抑制STAT3和AKT的磷酸化，诱导NSCLC细胞凋亡，与DDP联用后其抑制效果增强，EGFR/AKT和JAK2/STAT3通路也进一步被抑制。

Metastasis is the leading cause of cancer-related death. Despite extensive treatment, the prognosis for patients with metastatic cancer remains poor. In addition to conventional surgical resection, radiotherapy, immunotherapy, chemotherapy, and targeted therapy, various nanobiomaterials have attracted attention for their enhanced antitumor performance and low off-target effects. However, nanomedicines exhibit certain limitations in clinical applications, such as rapid clearance from the body, low biological stability, and poor targeting ability. Biomimetic methods utilize the natural biomembrane to mimic or hybridize nanoparticles and circumvent some of these limitations. Considering the involvement of immune cells in the tumor microenvironment of the metastatic cascade, biomimetic methods using immune cell membranes have been proposed with unique tumor-homing ability and high biocompatibility. In this review, we explore the impact of immune cells on various processes of tumor metastasis. Furthermore, we summarize the synthesis and applications of immune cell membrane-based nanocarriers increasing therapeutic efficacy against cancer metastases via immune evasion, prolonged circulation, enhanced tumor accumulation, and immunosuppression of the tumor microenvironment. Moreover, we describe the prospects and existing challenges in clinical translation.

OBJECTIVE: This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients. METHODS: This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group. RESULTS: Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation. CONCLUSION The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

PURPOSE: Multiple virus infections may affect clinical severity. We investigated the effect of coinfection of respiratory syncytial virus (RSV) and influenza virus with other respiratory viruses on clinical severity. METHODS: Data from 634 samples of a single tertiary hospital between September 2014 and April 2015 were analyzed for clinical characteristics (fever duration and O2 need, steroid use, and ICU care) between single infection and coinfection of RSV (n=290) and influenza virus (n=74) with 16 common respiratory viruses from hospitalized children. RESULTS: The RSV coinfection group (n=109) (3.1±2.7 days) showed significantly longer fever duration than the RSV single infection group (n=181) (2.6±2.6 days) (P=0.04), while there was no difference in O2 need, steroid use or ICU care in the 2 groups. The influenza coinfection group (n=38) showed significantly higher O2 need than the influenza single infection group (n=36) (21.1% vs. 5.6%, P=0.05), while there was no difference in fever duration between the 2 groups. CONCLUSION: The results indicate that RSV and Influenza coinfections can increase clinical severity and that the severity may be influenced by the nature of coinfecting viruses.

PURPOSE: To determine the relationship between vaginal reflux (VR) and urinary tract infection (UTI) in female children aged < 36 months. METHODS: A single center retrospective study was performed for 191 girls aged < 36 months, with a diagnosis of febrile UTI, who underwent a voiding cystourethrography (VCUG) for assessment of vesicoureteral reflux (VUR) at Sanggye Paik Hospital. Fifty-one girls, who underwent VCUG for assessment of congenital hydronephrosis or renal pelvis dilatation, without a UTI, formed the control group. The correlation between the presence and grade of VR and UTI was evaluated. RESULTS: The prevalence rate of VR was higher in the UTI (42.9%) than control (13.7%) group (P < 0.05), with a higher VR severity grade in the UTI (mean, 0.64) than control (mean, 0.18) group (P < 0.05). On subanalysis with age-matching (UTI group: n=126, age, 5.28±2.13 months; control group: n=22, age, 4.79±2.40 months; P=0.33), both VR prevalence (43.65% vs. 18.18%, P < 0.05) and grade (0.65 vs. 0.22, P < 0.05) remained higher in the UTI than control group. Presence and higher grade of VR were associated with UTI recurrence (P < 0.05). VR was correlated to urosepsis (P < 0.05). The renal defect rate of patients with VR (VR [+]/VUR [+]) was not different from that of patients without VR (74% vs. 52%, P=0.143) in the VUR group; however, it was higher than that of VR (+)/VUR (−) patients (74% vs. 32%, P=0.001). If a child with VR (+)/VUR (+) is exposed to a UTI, the risk of renal defect increases. CONCLUSION: Occurrence of VR is associated with UTI recurrence and urosepsis in pediatric female patients.
