Objective To analyze the application of NCompass nitinol stone retrieval basket in ureteroscopic holmium laser lithotripsy, and to evaluate its roles in reducing stone retropulsion and improving stone-free rate(SFR)and stone acquisition rate.Methods A retrospective analysis was conducted on the data of patients with upper ureteral stones>1 cm who underwent ureteroscopic holmium laser lithotripsy at China-Japan Friendship Hospital during Jan.2018 and Dec.2023, including 96 cases were in the NCompass group, and 68 cases in the non-basket group.The operation time, stone retropulsion rate, usage rate of flexible ureteroscopy, SFR and stone acquisition rate were compared between the two groups.Results There were no significant differences in the operation time [(29.2±8.4)min vs.(30.9±7.2)min, P=0.170] and stone retropulsion rate(15.6% vs. 27.9%, P=0.055)between the NCompass group and non-basket group.The NCompass group had significantly lower usage rate of flexible ureteroscopy than the non-basket group(24.0% vs. 47.1%, P=0.002), higher SFR 2 days(80.2% vs. 45.6%, P<0.001)and 1 month(93.8% vs. 83.8%, P=0.040)after operation, as well as the stone acquisition rates 2 days(100% vs. 44.1%, P<0.001)and 1 month(100% vs. 58.8%, P<0.001)after operation. Conclusion The NCompass nitinol stone retrieval basket plays dual roles in ureteroscopic holmium laser lithotripsy, which can effectively intercept stones and extract stone fragments, thus significantly improving the SFR and stone acquisition rate, and reducing stone retropulsion and the use of flexible ureteroscopy.

Acute lung injury (ALI) is a life-threatening condition characterized by uncontrolled pulmonary inflammatory responses, presenting high morbidity and mortality rates that pose serious threats to patient health. The pathogenesis of ALI involves complex interactions among pathological mechanisms including immune-inflammatory responses, disruption of the alveolar-capillary barrier, mesenchymal stem cell dysfunction, metabolic disorders, ferroptosis, and alterations in the gut microbiota. The dysregulation of programmed cell death (PCD) has increasingly emerged as a research focus. PCD represents a genetically regulated autonomous process of cell death, crucial for maintaining the internal stability of organisms. Recent studies indicate that multiple PCD modes, including apoptosis, pyroptosis, necroptosis, autophagy, and ferroptosis, participate in the development and progression of ALI by mediating pathological processes such as alveolar epithelial cell injury and vascular endothelial barrier disruption. Current therapeutic approaches for ALI encompass lung-protective ventilation, body fluid management, mesenchymal stem cell therapy, and pharmacological interventions. While these measures may alleviate clinical symptoms, they remain unable to reverse the pathological progression of lung injury. Traditional Chinese medicine (TCM) possesses the unique advantages of a holistic perspective and syndrome differentiation-based treatment, achieving breakthrough progress in targeted PCD intervention for ALI. It can mitigate pulmonary tissue injury by suppressing inflammatory responses, regulating immune function, and improving coagulation disorders, thereby delaying the onset and progression of ALI. This paper delves into the molecular mechanisms of PCD in ALI, systematically reviewing the effects of TCM extracts, active constituents (terpenoids, saponins, flavonoids, and phenols), and compound formulas (e.g., Qingjie Huagong prescription, Maxing Kugan Tang, and Yifei Jianpi prescription) in improving pulmonary epithelial cell function and mitigating lung injury by modulating PCD pathways. This review aims to provide theoretical underpinnings and novel directions for drug development in the clinical prevention and treatment of ALI.

Objective To construct a glioma microfluidic chip model to simulate tumor microenvironment for evaluating the medicinal efficacy of anti-glioma traditional Chinese medicines. Methods Glioblastoma cells U251 were seeded into microfluidic chips with different culture modes, and the cell viability and tumour microenvironment within the constructed model were characterized. Fluorescence staining was used to evaluate the effects of the positive drugs temozolomide (TMZ) and docetaxel (DOC) on the cell activity and apoptosis within the model, which was applied to evaluate the medicinal efficacy of the extracts of the herb Scutellaria barbata on gliomas. Results The cells in the constructed U251 microfluidic chip model displayed high viability and were able to mimic the hypoxic microenvironment of tumor to a certain extent. The viability of the U251 cells in the microfluidic chips decreased with the increasing of the concentration of the positive drug, and the viability of the 3D cultured U251 cells was higher than that in the 2D condition (P<0.05). The intracellular mitochondrial membrane potential decreased with the increasing of the concentration of the positive drug. And the 2 mg/ml Scutellaria barbata extract killed U251 cells to a certain extent and reduced the mitochondrial membrane potential of the cells in the model. Conclusion This study successfully constructed a microfluidic chip model of glioma that could effectively simulate the tumor microenvironment and rapidly evaluate the anti-tumor medicinal efficacy, which provided a new strategy for the medicinal efficacy evaluation and active components screening of anti-glioma traditional Chinese medicines.

Objective:To identify the risk factors for postoperative sleep disturbance (PSD) in patients undergoing spine surgery.Methods:In this case-control study, patients who underwent spine surgery from December 2023 to June 2024 at Beijing Tiantan Hospital of Capital Medical University, were selected as the subjects of the study. The quality of postoperative sleep was assessed using the Athens Insomnia Scale (AIS). The baseline characteristics and various perioperative indicators of the patients were collected. The patients were divided into PSD group and non-PSD group according to whether they had PSD. The variables with statistically significant differences from the univariate analysis were included in a multivariate logistic regression to identify the risk factors for PSD.Results:The results of the multivariate logistic regression analysis showed that preoperative sleep disturbance (odds ratio [ OR]=2.23, 95% confidence interval [ CI] 1.06-4.72, P=0.036), course of disease > 12 months ( OR=2.20, 95% CI 1.14-4.24, P=0.019) and AIS score > 2 on the night before surgery ( OR=2.06, 95% CI 1.02-4.16, P=0.045) were the independent risk factors for PSD in patients undergoing spine surgery. Conclusions:Preoperative sleep disturbance, course of disease > 12 months and AIS score > 2 on the night before surgery are independent risk factors for PSD in patients undergoing spine surgery.

Objective To explore the neurophysiological signatures of auditory event-related potentials(AERP)during propofol-induced graded sedation depths,and their correlations with sedation levels and behavioral responsiveness,and further to evaluate the feasibility of AERP components as potential biomarkers for quantifying consciousness states.Methods An auditory Oddball paradigm was used to evoke AERP responses in healthy volunteers under propofol-induced graded sedation.Linear mixed model was applied to explore the relationships between the mean amplitudes of AERP components[mismatch negativity(MMN);P300]and both sedation-induced conscious states[Modified Observer's Assessment of Alertness/sedation Scale(MOAA/S)scores]and behavioral performance(response accuracy).Results Twenty-two healthy volunteers were included.Data analysis revealed significant negative correlations between the mean amplitudes of MMN components[MMN-Dev:β=-0.62(-2.70--0.07),P=0.04;MMN-Nov:β=-0.15(-0.27--0.03),P=0.02]and MOAA/S scores during propofol sedation.Novel stimulus-evoked MMN amplitudes also correlated with response accuracy[MMN-Nov:β=-5.08(-7.78--2.37),P<0.01].There was a weak positive correlation between novel stimulus-evoked P300 amplitudes and MOAA/S scores[β=0.16(0.04-0.39),P=0.04],however,the correlation was no significant difference after adjusting for confounding factors including age,education level,and cognitive level.Conclusion The mean amplitude of MMN component elicited during auditory tasks was correlated with conscious states and behavioral accuracy under propofol-induced graded sedation.MMN holds promise as a potential neurophysiological indicator for quantifying conscious states or behavioral responsiveness during sedation.
