Yes-associated protein (YAP), the key transcriptional co-factor and downstream effector of the Hippo pathway, has emerged as one of the primary regulators of neural as well as glial cells. It has been detected in various glial cell types, including Schwann cells and olfactory ensheathing cells in the peripheral nervous system, as well as radial glial cells, ependymal cells, Bergmann glia, retinal Müller cells, astrocytes, oligodendrocytes, and microglia in the central nervous system. With the development of neuroscience, understanding the functions of YAP in the physiological or pathological processes of glia is advancing. In this review, we aim to summarize the roles and underlying mechanisms of YAP in glia and glia-related neurological diseases in an integrated perspective.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Objective To construct a prediction model for in-hospital mortality in the elderly(≥65 years)patients undergoing unsynchronous cardioversion in ICU and to evaluate its effectiveness.Methods A retrospective study was conducted on 276 elderly eligible patients in the ICU of the Ninth and the First Medical Centers of Chinese PLA General Hospital between June 2022 and August 2024.According to their clinical outcomes,they were divided into a non-in-hospital dead group(111 cases)and an in-hospital dead group(165 cases).Clinical data were collected,and pre-dictive factors for in-hospital mortality were screened.And then a nomogram prediction model was developed based on the obtained predictive factors,which was evaluated with ROC curve and deci-sion curve analyses.Results When compared to the non-in-hospital dead group,the in-hospital dead group had significantly higher heart rate,ratio of hemodialysis,and levels of alanine amin-otransferase,aspartate aminotransferase,lactate dehydrogenase,alkaline phosphatase,serum cre-atinine,blood glucose,lactate,low base excess,sequential organ failure assessment(SOFA)score,model for end-stage liver disease score,and larger proportions of ventricular fibrillation/flutter and structural heart disease induced by pulseless ventricular tachycardia,and had significantly lower Glasgow Coma Scale(GCS)(P＜0.05).Multivariate logistic regression analysis identified body temperature＞37℃(OR=0.426,95％CI:0.198-0.915,P=0.029),chronic obstructive pulmonary disease(OR=2.333,95％CI:1.217-4.473,P=0.011),GCS score(OR=0.622,95％CI:0.410-0.944,P=0.026),hemoglobin(OR=0.817,95％CI:0.715-0.934,P=0.003),lactate(OR=1.365,95％CI:1.174-1.587,P=0.000),heart rate＞100 bpm(OR=2.757,95％CI:1.397-5.441,P=0.003),and SOFA score(OR=1.112,95％CI:1.032-1.198,P=0.005)as pre-dictors of in-hospital mortality.ROC curve analysis showed an AUC value of above indicators combined together in the prediction was 0.797,with a sensitivity of 76.97％and a specificity of 65.77％.Calibration curve analysis demonstrated good consistency between predicted and observed outcomes.Decision curve analysis indicated favorable clinical utility of the model.Conclusion This study identifies independent risk factors for in-hospital mortality among elderly patients in the ICU who underwent asynchronous cardioversion.Based on these factors,a nomo-gram model is established,demonstrating good discrimination,calibration,and model fit,with high clinical applicability.

BACKGROUND:Previous studies have shown that knee joint moment changes in patients with knee osteoarthritis,but there are few reports on the correlation of moment changes with knee extensor muscle strength and gait spatiotemporal parameters. OBJECTIVE:To explore the correlation of knee extensor muscle strength and gait spatiotemporal parameters with peak knee flexion moment and knee adduction moment in female patients with knee osteoarthritis. METHODS:Twenty knee osteoarthritis female patients with single knee disease hospitalized in Guizhou Hospital,Beijing Jishuitan Hospital from February to August 2022 were selected as the knee osteoarthritis group,and an additional 20 healthy females without musculoskeletal disease were selected as the control group.The knee extensor force at 60(°)/s was measured with the Biodex isokinetic instrument.The gait spatiotemporal parameters and peak knee flexion moment and knee adduction moment were collected with the Italian BTS infrared motion capture system and force measuring platform.Pearson correlation analysis was used to explore the correlation of muscle strength and gait spatiotemporal parameters with peak knee adduction moment and knee flexion moment,and the variables significantly related to knee joint moment were further included in the multiple stepwise regression analysis. RESULTS AND CONCLUSION:(1)Compared with the control group,the knee osteoarthritis group had significantly lower knee extensor force,step speed,step frequency,step length,step width,peak knee adduction moment and knee flexion moment at 60(°)/s(P<0.05).(2)Pearson correlation analysis showed that the 60(°)/s centripetal extensor force,step speed,step frequency and step length were positively correlated with the peak knee flexion moment,and negatively correlated with the peak knee adduction moment,with a statistically significant difference(P<0.05).(3)The results of multiple stepwise regression showed that step speed and 60(°)/s knee extensor force were the strongest predictors of peak knee flexion moment,and the total R2 value of the two factors was 0.426,indicating that 42.6%of the total variance of this parameter could be explained.Step length and 60(°)/s centripetal extensor force were the strongest predictors of peak knee adduction moment.The total R2 value of the two factors was 0.602,indicating that 60.2%of the total variance of this parameter could be explained.(4)It is concluded that knee extensor strength,step speed and step length are the main variables affecting peak knee adduction moment and knee flexion moment.Therefore,these variables can be used for clinical gait monitoring and guidance to change knee joint load during knee osteoarthritis rehabilitation.

Objective:To study the safety and efficiency of endovascular treatment in pediatric severe cerebral venous sinus thrombosis(CVST).Methods:This was a case series study.Data of pediatric severe CVST patients who received endovascular treatment in the Department of Neurointerventional, the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2023 were retrospectively analyzed.The technical success rate, periprocedural complications, neurologic and radiologic outcomes were collected to study the safety and efficacy of endovascular treatment in pediatric severe CVST.Results:A total of 15 patients were included in this study, including 6 males(40.0%) and 9 females(60.0%) with a mean age of(14.60±2.26) years.The modified Rankin Scale score(mRS) before endovascular treatment was(3.47±1.06) points, and the time from onset to endovascular treatment was 17(12-26) days.Thirteen patients(86.7%) received mechanical thrombectomy through catheter aspiration and/or stent-retriever thrombectomy followed or not followed by intrasinus thrombolysis(IST), and 2 patients(13.3%) received IST only.The technical success rate was 100%.Three patients(20.0%) had periprocedural complications.Ten patients(66.7%) had mRS≤2 points at discharge.Twelve patients(80.0%) had valuable neurologic and radiologic follow-ups with a duration of 9.5(3.5-19.0) months, and they all had mRS≤2 points.Among the 12 patients, 8(66.7%) had good cerebral venous recanalization.Conclusions:Endovascular treatment is technically feasible in pediatric severe CVST patients, with acceptable safety and efficacy.

Objective:To evaluate the necessity, safety and efficacy of endovascular treatment for cerebral infarction caused by middle cerebral artery (MCA) stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.Methods:The clinical and surgical data of patients with MCA atherosclerotic disease who underwent endovascular treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to October 2021 were retrospectively analyzed. A total of 6 patients with cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery were selected. The preoperative and postoperative clinical imaging characteristics, perioperative complications and follow-up of these 6 patients were summarized and evaluated.Results:After the endovascular treatment, the imaging of the lenticulostriate artery in all the 6 patients was clearer than that before the operation, and the number of main trunks of the lenticulostriate artery shown by imaging in 2 patients was more than that before operation. The computer tomography perfusion of 6 patients after the endovascular treatment showed that perfusion in the supply area of the lenticulostriate artery was significantly improved compared with pre-operation. No stroke, transient ischemic attack (TIA) and death occurred during the perioperative period. The time of clinical follow-up was 360 (322, 495) days, and there were no stroke, TIA or death occurring in the corresponding artery. All the 6 patients underwent imaging follow-up, of which 3 patients underwent digital subtraction angiography and 3 underwent CT angiography. The lumen of the target vessels showed patency in all patients.Conclusions:With rigorous imaging evaluation, endovascular treatment may be safe and effective for cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.
