Abstract
Iron overload can lead to oxidative stress and intestinal damage and happens frequently during blood transfusions and iron supplementation. However, how iron overload influences intestinal mucosa remains unknown. Here, the aim of current study was to investigate the effects of iron overload on the proliferation and differentiation of intestinal stem cells (ISCs). An iron overload mouse model was established by intraperitoneal injection of 120 mg/kg body weight iron dextran once a fortnight for a duration of 12 weeks, and an iron overload enteroid model was produced by treatment with 3 mM or 10 mM of ferric ammonium citrate for 24 h. We found that iron overload caused damage to intestinal morphology with a 64 % reduction in villus height/crypt depth ratio, and microvilli injury in the duodenum. Iron overload mediated epithelial function by inhibiting the expression of nutrient transporters and enhancing the expression of secretory factors in the duodenum. Meanwhile, iron overload inhibited the proliferation of ISCs and regulated their differentiation into secretory mature cells, such as goblet cells, through inhibiting Notch signaling pathway both in mice and enteroid. Furthermore, iron overload caused oxidative stress and ferroptosis in intestinal epithelial cells. In addition, ferroptosis could also inhibit Notch signaling pathway, and affected the proliferation and differentiation of ISCs. These findings reveal the regulatory role of iron overload on the proliferation and differentiation of ISCs, providing a new insight into the internal mechanism of iron overload affecting intestinal health, and offering important theoretical basis for the scientific application of iron nutrition regulation.

Abstract
AIMS The findings from previous epidemiological studies of the association between regional body fat and depressive symptoms have been unclear. We aimed to determine the association between the body fat in different regions and depressive symptoms based on data from the National Health and Nutrition Examination Survey (NHANES). METHODS This study included 3393 participants aged ≥ 20 years from the NHANES performed during 2011-2018. Depressive symptoms were assessed using the Patient Health Questionnaire-9. The fat mass (FM) was measured in different regions using dual-energy X-ray absorptiometry to determine the total FM, trunk FM, arm FM, and leg FM. The FM index (FMI) was obtained by dividing the FM in kilograms by the square of the body height in meters. Weighted data were calculated in accordance with analytical guidelines. Linear logistic regression models were used to quantify the association between regional FMI and depressive symptoms. Univariate and stratified analyses were also performed. RESULTS The participants in this study comprised 2066 males and 1327 females. There were 404 (11.91%) participants with depressive symptoms, who were aged 40.89 ± 11.74 years and had a body mass index of 30.07 ± 7.82 kg/m². A significant association was found between total FMI and depressive symptoms. In the fully adjusted multivariate regression model, a higher total FMI (odds ratio = 2.18, 95% confidence interval [CI] = 1.08-4.39) was related to a higher risk of depressive symptoms, while increased total FMI (β = 1.55, 95% CI = 0.65-2.44, p = 0.001), trunk FMI (β = 0.57, 95% CI = 0.04-1.10, p = 0.036), and arm FMI (β = 0.96, 95% CI = 0.33-1.59, p = 0.004) were significantly associated with PHQ-9 (Patient Health Questionnaire-9) scores, whereas the leg FMI was not (p = 0.102). The weighted association between total FMI and depressive symptoms did not differ significantly between most of the subpopulations (all p values for interaction > 0.05). The risk of having depression was higher in individuals who were non-Hispanic Whites, smokers, drinkers, obese, and had diabetes and thyroid problems (p < 0.05). CONCLUSION These findings suggest that the population with a higher regional FMI is more likely to have depressive symptoms, especially in those who also have an increased total FMI. The association is more pronounced in individuals who are smokers, drinkers, obese, and have diabetes and thyroid problems.

Abstract
Principal component analysis (PCA) is one of the most widely used unsupervised dimensionality reduction algorithms, but it is very sensitive to outliers because the squared l2 -norm is used as distance metric. Recently, many scholars have devoted themselves to solving this difficulty. They learn the projection matrix from minimum reconstruction error or maximum projection variance as the starting point, which leads them to ignore a serious problem, that is, the original PCA learns the projection matrix by minimizing the reconstruction error and maximizing the projection variance simultaneously, but they only consider one of them, which imposes various limitations on the performance of model. To solve this problem, we propose a novel robust principal component analysis via joint reconstruction and projection, namely, RPCA-RP, which combines reconstruction error and projection variance to fully mine the potential information of data. Furthermore, we carefully design a discrete weight for model to implicitly distinguish between normal data and outliers, so as to easily remove outliers and improve the robustness of method. In addition, we also unexpectedly discovered that our method has anomaly detection capabilities. Subsequently, an effective iterative algorithm is explored to solve this problem and perform related theoretical analysis. Extensive experimental results on several real-world datasets and RGB large-scale dataset demonstrate the superiority of our method.

Abstract
BACKGROUND Movement and tone disorders in children and young adults with cerebral palsy are a great source of disability. Deep brain stimulation (DBS) of basal ganglia targets has a major role in the treatment of isolated dystonias, but its efficacy in dyskinetic cerebral palsy (DCP) is lower, due to structural basal ganglia and thalamic damage and lack of improvement of comorbid choreoathetosis and spasticity. The cerebellum is an attractive target for DBS in DCP since it is frequently spared from hypoxic ischemic damage, it has a significant role in dystonia network models, and small studies have shown promise of dentate stimulation in improving CP-related movement and tone disorders. METHODS Ten children and young adults with DCP and disabling movement disorders with or without spasticity will undergo bilateral DBS in the dorsal dentate nucleus, with the most distal contact ending in the superior cerebellar peduncle. We will implant Medtronic Percept, a bidirectional neurostimulator that can sense and store brain activity and deliver DBS therapy. The efficacy of cerebellar DBS in improving quality of life and motor outcomes will be tested by a series of N-of-1 clinical trials. Each N-of-1 trial will consist of three blocks, each consisting of one month of effective stimulation and one month of sham stimulation in a random order with weekly motor and quality of life scales as primary and secondary outcomes. In addition, we will characterize abnormal patterns of cerebellar oscillatory activity measured by local field potentials from the intracranial electrodes related to clinical assessments and wearable monitors. Pre- and 12-month postoperative volumetric structural and functional MRI and diffusion tensor imaging will be used to identify candidate imaging markers of baseline disease severity and response to DBS. DISCUSSION Our goal is to test a cerebellar neuromodulation therapy that produces meaningful changes in function and well-being for people with CP, obtain a mechanistic understanding of the underlying brain network disorder, and identify physiological and imaging-based predictors of outcomes useful in planning further studies. TRIAL REGISTRATION ClinicalTrials.gov NCT06122675, first registered November 7, 2023.

Abstract
Triptolide, a natural bioactive compound derived from herbal medicine Tripterygium wilfordii, has multiple biological activities including anti-cancer effect, which is being tested in clinical trials for treating cancers. However, the exact mechanism by which Triptolide exerts its cytotoxic effects, particularly its specific protein targets, remains unclear. Here, we show that Triptolide effectively induces cytotoxicity in gastric cancer cells by increasing reactive oxygen species (ROS) levels. Further investigations reveal that ROS accumulation contributes to the induction of Endoplasmic Reticulum (ER) stress, and subsequently autophagy induction in response to Triptolide. Meanwhile, this autophagy is cytoprotective. Interestingly, through activity-based protein profiling (ABPP) approach, we identify peroxiredoxins-2 (PRDX2), a component of the key enzyme systems that act in the defense against oxidative stress and protect cells against hydroperoxides, as direct binding target of Triptolide. By covalently binding to PRDX2 to inhibit its antioxidant activity, Triptolide increases ROS levels. Moreover, overexpression of PRDX2 inhibits and knockdown of the expression of PRDX2 increases Triptolide-induced apoptosis. Collectively, these results indicate PRDX2 as a direct target of Triptolides for inducing apoptosis. Our results not only provide novel insight into the underlying mechanisms of Triptolide-induced cytotoxic effects, but also indicate PRDX2 as a promising potential therapeutic target for developing anti-gastric cancer agents.

Abstract
INTRODUCTION Passive smoking is considered a major public health issue in China. Prospective evidence regarding the link between secondhand smoke (SHS) and ischemic stroke in China is scarce. METHODS The China Kadoorie Biobank (CKB) study in Liuzhou City recruited 50,174 participants during 2004-2008. Of these 30,456 never-smokers were included in our study. The median follow-up period was 10.7 years. The incidence of ischemic stroke was obtained through the China Disease Surveillance Points (DSP) system and the Health Insurance (HI) database. Cox proportional risk models were used to evaluate the association between SHS exposure and ischemic stroke. RESULTS During 320,678 person-years of follow-up, there were 2059 patients with ischemic stroke observed and the incidence of ischemic stroke was 6.42 per thousand person-years. Participants exposed to SHS daily faced a 21 % higher risk of ischemic stroke (HR = 1.21, 95 %CI: 1.09-1.34) compared to those exposed to SHS less than once a week. Subgroup analyses revealed that daily SHS exposure was linked to heightened risk of ischemic stroke among women, non-employed, and non-weekly tea drinkers. CONCLUSIONS Daily SHS exposure was associated with higher risks of ischemic stroke. Proactive tobacco control strategies are necessary to decrease the risk of ischemic stroke in never smokers.

Abstract
Osteosarcoma, the most prevalent primary bone tumor in children and young adults, can often be successfully treated with standard chemotherapy and surgery when diagnosed at an early stage. However, patients presenting with metastases face significant challenges in achieving a cure. Despite advancements in classical therapies over the past few decades, clinical outcomes for osteosarcoma have not substantially improved. Recently, there has been increased understanding of the biology of osteosarcoma, leading to the identification of new therapeutic targets. One such target is MET, a tyrosine kinase receptor for Hepatocyte Growth Factor (HGF) encoded by the MET gene. In vitro and in vivo studies have demonstrated that the HGF/MET pathway plays a crucial role in cancer growth, invasion, metastasis, and drug resistance across various cancers. Clinical trials targeting this pathway are already underway for lung cancer and hepatocellular carcinoma. Moreover, MET has also been implicated in promoting osteosarcoma progression. This review summarizes 3 decades' worth of research on MET's involvement in osteosarcoma and further explores its potential as a therapeutic target for patients with this disease.

Abstract
Perovskite photovoltaics, typically based on a solution-processed perovskite layer with a film thickness of a few hundred nanometres, have emerged as a leading thin-film photovoltaic technology. Nevertheless, many critical issues pose challenges to its commercialization progress, including industrial compatibility, stability, scalability and reliability. A thicker perovskite film on a scale of micrometres could mitigate these issues. However, the efficiencies of thick-film perovskite cells lag behind those with nanometre film thickness. With the mechanism remaining elusive, the community has long been under the impression that the limiting factor lies in the short carrier lifetime as a result of defects. Here, by constructing a perovskite system with extraordinarily long carrier lifetime, we rule out the restrictions of carrier lifetime on the device performance. Through this, we unveil the critical role of the ignored lattice strain in thick films. Our results provide insights into the factors limiting the performance of thick-film perovskite devices.

Abstract
Patients with schizophrenia (SCZ) smoke up to three times more than general people. However, there are conflicting results regarding the relationship between tobacco smoke and clinical symptom severity in SCZ. The aim of this study was to assess the impact of smoking on clinical symptoms after antipsychotic treatment in a 12-week cohort study after controlling for confounding factors. One hundred and forty-five male patients with drug-naïve first-episode (DNFE) SCZ received antipsychotic monotherapy for 12 weeks. Symptom severity was assessed at baseline and at week 12 by the Positive and Negative Syndrome Scale (PANSS). We found no differences in clinical symptoms among male smokers with SCZ compared with male nonsmokers. However, male smokers showed greater improvement in negative symptoms after 12 weeks of treatment, controlling for age, years of education, onset age, and baseline body mass index (BMI). Our study showed that after 12 weeks of treatment with antipsychotics, male smokers showed greater improvement in negative symptoms than male nonsmokers.

Abstract
Hepatic ischemia/reperfusion injury (HIRI) is a common and inevitable factor leading to poor prognosis in various liver diseases, making the outcomes of current treatments in clinic unsatisfactory. Metformin has been demonstrated to be beneficial to alleviate HIRI in recent studies, however, the underpinning mechanism remains unclear. In this study, we found metformin mitigates HIRI-induced ferroptosis through reshaped gut microbiota in mice, which was confirmed by the results of fecal microbiota transplantation treatment but showed the elimination of the beneficial effects when gut bacteria were depleted using antibiotics. Detailedly, through 16S rRNA and metagenomic sequencing, we identified that the metformin-reshaped microbiota was characterized by the increase of gamma-aminobutyric acid (GABA) producing bacteria. This increase was further confirmed by the elevation of GABA synthesis key enzymes, glutamic acid decarboxylase and putrescine aminotransferase, in gut microbes of metformin-treated mice and healthy volunteers. Furthermore, the benefit of GABA against HIRI-induced ferroptosis was demonstrated in GABA-treated mice. Collectively, our data indicate that metformin can mitigate HIRI-induced ferroptosis by reshaped gut microbiota, with GABA identified as a key metabolite.

Abstract
Nocardia is a rarely encountered opportunistic gram-positive bacterium that exhibits marked invasiveness and dissemination. Typically, acquired through trauma or inhalation, this pathogen primarily affects immunocompromised individuals and is a potentially life-threatening risk in severe cases. Nocardia otitidiscaviarum is a particularly rare subtype of Nocardia infection, and the occurrence of concurrent Aspergillus infection is extremely rare. In cases where both infections manifest concomitantly, rapid and accurate diagnosis is essential to facilitate the subsequent selection of appropriate anti-infective interventions. This paper reported the diagnostic and therapeutic experience in managing a case of pulmonary co-infection with Nocardia otitidiscaviarum and Aspergillus. The patient presented with an acute onset, rapid progression, and early manifestation of respiratory failure. The diagnostic process included respiratory pathogen culture and bronchoscopy, which was supplemented with targeted next-generation sequencing (tNGS). These comprehensive diagnostic modalities led to the identification of pulmonary co-infection with Nocardia otitidiscaviarum and Aspergillus. After adjustment of the antibiotic regimen, the patient's condition improved rapidly, culminating in a timely discharge.

Abstract
Purpose: Papillary thyroid cancer (PTC) stands as one of the most prevalent types of thyroid cancers, characterized by a propensity for in-situ recurrence and distant metastasis. The high mobility group protein (HMGB1), a conserved nuclear protein, plays a pivotal role in carcinogenesis by stimulating tumor cell growth and migration. Nevertheless, the underlying mechanism driving aberrant HMGB1 expression in PTC necessitates further elucidation. Materials and methods: Our study unraveled the impact of low and overexpression of USP15 on the proliferation, invasion, and metastasis of PTC cells. Through a comprehensive array of molecular techniques, we uncovered the intricate relationship between HMGB1 and USP15 in the progression of PTC. Results: In this study, we identified USP15, a deubiquitinase in the ubiquitin-specific proteases family, as a true deubiquitylase of HMGB1 in PTC. USP15 was shown to interact with HMGB1 in a deubiquitination activity-dependent manner, deubiquitinating and stabilizing HMGB1. USP15 depletion significantly decreased PTC cell proliferation, migration, and invasion. In addition, the effects induced by USP15 depletion could be rescued by further HMGB1 overexpression. But when HMGB1 is knocked down, even overexpression of USP15 could not promote the progression of PTC cells. Conclusion: In essence, our discoveries shed light on the previously uncharted catalytic role of USP15 as a deubiquitinating enzyme targeting HMGB1, offering a promising avenue for potential therapeutic interventions in the management of PTC.

Abstract
Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This is a retrospective case series study. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged (M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery. There were 15 cases of the right coronary artery from the left aortic sinus of Valsalva, 6 cases of left coronary artery from the right aortic sinus of Valsalva, 3 cases of the sigle coronary artery. Only 3 patients had no obvious related symptoms (2 cases were complicated with a positive exercise stress test and 1 case with other intracardiac malformations), 21 cases had a history of chest tightness, chest pain, or syncope after exercise. Three patients suffered syncope after exercise and underwent cardiopulmonary resuscitation (2 cases were treated with an extracorporeal membrane oxygenerator (ECMO)). The gap from the first symptom to the diagnosis was 4.0 (11.5) months (range: 0.2 to 84.0 months). The detection rate of coronary artery abnormalities suggested by the first cardiac ultrasound was only 37.5% (9/24). Seven patients were complicated with other cardiac diseases (4 cases with congenital heart defects, 2 cases with coronary atherosclerotic heart disease, 1 case with mitral valve disease). Results: All 24 patients underwent surgical treatment (23 cases underwent abnormal coronary artery unroofing, 1 case underwent coronary artery bypass grafting), and 5 patients underwent other intracardiac malformation correction at the same time. There were no death or surgery related complications in the hospital for 30 days after the operation. A patient with preoperative extracorporeal cardiopulmonary resuscitation was continuously assisted by ECMO after emergency AAOCA correction and had complications such as limb ischemia necrosis and renal dysfunction after the operation. During the follow-up of 2.2 (3.3) years (range: 1 month to 7.2 years), one patient who previously underwent percutaneous transluminal coronary angioplasty with a stent implant experienced significant postoperative symptomatic relief, and the other discharged patients had no related symptoms. Conclusions: The accurate rate of initial diagnosis for high-risk AAOCA is still low, but the risk of cardiovascular accidents is high. For sports-related chest pain and other symptoms, more attention should be paid to the detection of AAOCA, especially for adolescents. Exercise stress testing can be helpful in evaluating the cardiovascular risk of asymptomatic AAOCA. Instant surgical treatment can achieve satisfactory curative effects.

Abstract
BACKGROUND Paediatric healthcare is always highlighted in medical and health care system reform in China. Zhejiang Province established a new diagnosis-related group (DRG) point payment reform in 2020 to regulate provider behaviours and control medical costs. We conducted this study to evaluate impacts of the DRG point payment policy on provider behaviours and resource usage in children's medical services. METHODS Data from patients' discharge records from July 2019 to December 2020 in Children's Hospital, Zhejiang University School of Medicine were collected for analysis. We employed the interrupted time series approach to reveal the trend before and after the DRG point payment reform and the difference-in-differences analysis to estimate the independent outcome changes attributed to the reform. RESULTS We found that the upward trend of length of stay slightly slowed, and the total costs began to decrease at the post-policy stage. Although independent effects of the reform were not presented among the whole sample, the length of stay and hospitalisation costs of moderate-hospital-stay paediatric patients, non-surgical patients, and infant patients were found to decrease rapidly after the reform. CONCLUSION DRG point payments can changed the provider behaviours and eventually reduce healthcare resource usage in children's medical services.

Abstract
Bacille Calmette-Guérin (BCG) is a live strain of Mycobacterium bovis (M.bovis) for use as an attenuated vaccine to prevent tuberculosis (TB) infection, while it could also lead to an infection in immunodeficient patients. M.bovis could infect patients with immunodeficiency via BCG vaccination. Disseminated BCG disease (BCGosis) is extremely rare and has a high mortality rate. This article presents a case of a 3-month-old patient with disseminated BCG infection who was initially diagnosed with hemophagocytic syndrome (HPS) and eventually found to have X-linked severe combined immunodeficiency (X-SCID). M.bovis and its drug resistance genes were identified by metagenomics next-generation sequencing (mNGS) combined with targeted next-generation sequencing (tNGS) in blood and cerebrospinal fluid. Whole exome sequencing (WES) revealed a pathogenic variant in the common γ-chain gene (IL2RG), confirming X-SCID. Finally, antituberculosis therapy and umbilical cord blood transplantation were given to the patient. He was successfully cured of BCGosis, and his immune function was restored. The mNGS combined with the tNGS provided effective methods for diagnosing rare BCG infections in children. Their combined application significantly improved the sensitivity and specificity of the detection of M.bovis.

Abstract
Objective: To evaluate the intermediate and long-term outcomes and technical aspects of transcatheter closure (TCC) of coronary cameral fistulas (CCF) in pediatric patients. Methods: This was a case-control study. All pediatric patients with CCF who underwent TCC between January 2005 and December 2019 were retrospectively reviewed. Data was collected from medical records, including demographic characteristics, procedural details, intraoperative and postoperative serious adverse events, follow-up results and prognosis. Patients with serious adverse events and without serious adverse events were compared regarding their clinical features and CCF characteristics. Comparisons between groups were performed with independent sample t test, chi-square test or Fisher exact test. Results: A total of 66 CCF patients (34 boys, 32 girls, 3.9 (1.9, 6.2) years old, 15 (11, 20) kg) underwent attempted TCC. All of the CCF were all medium or large fistulas including 55 proximal fistulas (83%) and 11 distal fistulas (17%). The CCF originated more frequently from the right coronary artery (38 cases (58%)), followed by the left coronary artery (28 cases (42%)). The incidence of coronary artery aneurysms (CAA) was 61% (40/66).Procedural treatment was achieved in 64 patients and procedural success was achieved in 59 patients (92%). Six (9%) serious adverse events occurred in 5 patients during the perioperative period. Acute complications included procedure-related death in one patient and acute myocardial infarction in one patient. Periprocedural complications occurred in 3 patients at one day postoperatively including acute myocardial infarction (2 cases), occluder detachment (1 case), and tricuspid chordae tendinae rupture (1 case). Clinical follow-up data were available in 58 of the 62 patients who underwent initial successful TCC with a follow-up period of 9.3 (6.5, 13.4) years. Ten adverse events occurred in 9 patients including 5 complications consisted of aortic valve perforation (1 case), coronary thrombosis (1 case), progressive aneurysmal dilation after reintervention (1 case), and new-onset tricuspid valve prolapse with significant regurgitation (2 cases) and large residual shunts due to fistula recanalization (5 cases). Therefore, the incidence of intermediate and long-term adverse events was 17% (10/58). During the periprocedural and follow-up period, 16 adverse events occurred in 13 patients, whereas no adverse events occurred in 51 patients. Patients with seriovs adverse events presented with larger proportion of large CCF (11/13 vs. 39% (20/51), P=0.005), giant CAA (10/13 vs.14% (7/51), P=0.030), and higher mean pulmonary artery pressure ((20±9) vs.(16±6) mmHg, 1 mmHg=0.133 kPa, t=2.02, P=0.048) compared to patients without serious adverse events. Conclusions: TCC in CCF children appears to be effective with favorable intermediate and long-term outcomes. Strict indication of TCC is mandatory.

Abstract
Kupffer cells are liver resident macrophages and play critical role in fatty liver disease, yet the underlying mechanisms remain unclear. Here, we show that activation of G-protein coupled receptor 3 (GPR3) in Kupffer cells stimulates glycolysis and protects mice from obesity and fatty liver disease. GPR3 activation induces a rapid increase in glycolysis via formation of complexes between β-arrestin2 and key glycolytic enzymes as well as sustained increase in glycolysis through transcription of glycolytic genes. In mice, GPR3 activation in Kupffer cells results in enhanced glycolysis, reduced inflammation and inhibition of high-fat diet induced obesity and liver pathogenesis. In human fatty liver biopsies, GPR3 activation increases expression of glycolytic genes and reduces expression of inflammatory genes in a population of disease-associated macrophages. These findings identify GPR3 activation as a pivotal mechanism for metabolic reprogramming of Kupffer cells and as a potential approach for treating fatty liver disease.

Abstract
Invariant natural killer T cells are a rare, heterogeneous T-cell subset with cytotoxic and immunomodulatory properties. During thymic development, murine invariant natural killer T cells go through different maturation stages differentiating into distinct sublineages, namely, invariant natural killer T1, 2, and 17 cells. Recent reports indicate that invariant natural killer T2 cells display immature properties and give rise to other subsets, whereas invariant natural killer T1 cells seem to be terminally differentiated. Whether human invariant natural killer T cells follow a similar differentiation model is still unknown. To define the maturation stages and assess the sublineage commitment of human invariant natural killer T cells during thymic development, in this study, we performed single-cell RNA sequencing analysis on human Vα24+Vβ11+ invariant natural killer T cells isolated from thymocytes. We show that these invariant natural killer T cells displayed heterogeneity, and our unsupervised analysis identified 5 clusters representing different maturation stages, from an immature profile with high expression of genes important for invariant natural killer T cell development and proliferation to a mature, fully differentiated profile with high levels of cytotoxic effector molecules. Evaluation of expression of sublineage-defining gene sets revealed mainly cells with an invariant natural killer T2 signature in the most immature cluster, whereas the more differentiated ones displayed an invariant natural killer T1 signature. Combined analysis with a publicly available single-cell RNA sequencing data set of human invariant natural killer T cells from peripheral blood suggested that the 2 main subsets exist both in thymus and in the periphery, while a third more immature one was restricted to the thymus. Our data point to the existence of different maturation stages of human thymic invariant natural killer T cells and provide evidence for sublineage commitment of invariant natural killer T cells in the human thymus.

Abstract
Objective: To investigate the distribution characteristics of cognition-related lifestyles of elderly in communities and explore the integrated effects on early cognitive decline. Methods: The participants were from the Project of Prevention and Intervention of Neurodegenerative Disease for Elderly in China. A total of 2 537 older adults aged ≥60 years without dementia in the 2015 baseline survey and the 2017 follow-up survey were included. The information about their cognition-related lifestyles, including physical exercise, social interaction, leisure activity, sleep quality, smoking status, and alcohol consumption, were collected through questionnaire survey and the integrated scores were calculated. Multivariate logistic regression analysis was used to assess the association between integrated cognition-related lifestyle score and early cognitive decline. Results: In the 2 537 older adults surveyed, 28.7% had score of 5-6, while only 4.8% had high scores for all 6 healthy lifestyles. Significant differences in healthy lifestyle factor distributions were observed between men and women. Multivariate logistic regression model showed that the risks for early cognitive decline in the older adults who had lifestyle score of 4 and 5-6 were lower than that in those with lifestyle score of 0-3 (OR=0.683, 95%CI: 0.457-1.019; OR=0.623, 95%CI: 0.398-0.976; trend P=0.030). In the women, the risks for early cognitive decline was lower in groups with score of 4 and 5-6 than in group with score of 0-3 (OR=0.491, 95%CI: 0.297-0.812; OR=0.556, 95%CI: 0.332-0.929; trend P=0.024). Conclusion: Cognition-related healthy lifestyles are associated with significantly lower risk for early cognitive decline in the elderly, especially in women.

Abstract
About one third of patients with diffuse large B-cell lymphoma (DLBCL) have a relapsing/refractory (R/R) disease after first line chemo-immunotherapy, with particularly poor outcomes observed in patients with primary refractory disease and early relapse. CD19 specific chimeric antigen receptor (CAR) T cell therapy is a game changer that results in durable and complete response rates in almost half of the patients with R/R DLBCL. Other emerging CD19-targeting therapies include monoclonal antibodies, bispecific antibodies and targeting antibody-drug conjugates, which also show encouraging results. However, the timing and sequencing of different anti-CD19-targeting agents and how they might interfere with subsequent CAR T cell treatment is still unclear. In this review, we summarize the results of the pivotal clinical trials as well as evidence from real-world series of the use of different CD19-targeting approved agents. We discuss the effect of various therapies on CD19 expression and its implications for treatment sequencing.

Abstract
Objective: To investigate whether heat shock protein 90 (HSP90) participates in the necroptosis of C57BL/6 mouse neurons and spatial memory impairment induced by Aluminum maltol [Al (mal) (3)] through RIP1/RIP3/MLKL pathway. Methods: In March 2022, Thirty-two C57 mice were randomly divided into control group, Low dose group, a medium dose group, and a high-dose group, with 8 mice in each group, and injected intraperitoneally with physiological saline, 20, 40, and 80, respectivelyμmol/kgAl (mal) (3) was administered, it was injected 5 days a week and discontinued 2 days for 60 days. Morris water maze test was used to test the spatial learning and memory ability of mice. Nissl staining was used to observe the pathological changes of brain tissue. The protein expression levels of RIP1, RIP3, MLKL and HSP90 in hippocampus were determined by Western blotting. Results: In the water maze experiment, compared with the control group, the number of mice crossing the platform decreased in each dose group, the difference was statistically significant (H=9.50, P=0.023), and the number of mice crossing the platform was statistically significant among each dose group (P <0.05). Compared with the control group, the number of hippocampal nerve cells in each dose group decreased, the arrangement was disordered, and the Nissellite bodies decreased. Western blotting results showed that compared with the control group, the expression level of RIP1 protein in the hippocampus of mice in high-dose group was higher, and the difference was statistically significant (P <0.05). The expression levels of RIP3, MLKL and HSP90 in hippocampal tissue of mice in medium and high dose groups were increased, and the differences were statistically significant (P<0.05). After siRNA intervention decreased the expression of HSP90 protein, the expressions of HSP90, RIP1, RIP3 and MLKL in Al (mal) (3) groups were increased, and the differences were statistically significant (P<0.05) . Conclusion: Through RIP1/RIP3/MLKL pathway, HSP90 is involved in neuronal programmed necrosis and spatial memory impairment induced by maltol aluminum in C57 mice.

Abstract
PURPOSE Capecitabine has extensive utilization in the treatment of diverse solid tumors, and its efficacy has been substantiated. Its oral administration and minimal toxicity in clinical practice render it advantageous. Nevertheless, uncertainty remains regarding whether capecitabine can substitute anthracycline drugs in chemotherapy regimens to achieve a lower risk of anthracycline-induced degradation. Consequently, we conducted a meta-analysis of randomized controlled trials (RCTs) to assess the potential of capecitabine as a replacement for anthracycline drugs in chemotherapy regimens for breast cancer. METHODS We systematically searched PubMed, Embase, Web of Science, and the Cochrane Controlled Trials Register (CENTRAL) to retrieve eligible studies published before July 18, 2023. Two independent reviewers extracted relevant data from the included studies using a pre-established data extraction form. The primary endpoints of interest encompassed overall survival (OS) and progression-free survival (PFS) for postoperative adjuvant therapy, as well as pathological complete response (PCR) following neoadjuvant therapy. Adverse events were considered as secondary outcomes. The statistical analysis was performed using Revman 5.4.1. RESULTS A total of six studies involving 2348 breast cancer patients were deemed eligible according to the selection criteria. The pooled meta-analysis revealed that there were no statistically significant differences observed in the primary outcomes of overall survival (OS) (HR 1.06, 95% CI 0.88-1.28) and progression-free survival (PFS) (HR 1.10, 95% CI 0.90-1.34) across the four postoperative adjuvant chemotherapy trials, as well as in the two neoadjuvant chemotherapy trials with respect to the primary outcome of pathological complete response (PCR) (OR 1.65, 95% CI 0.93-2.95) when comparing regimens containing anthracycline drugs to those without. In terms of adverse events, the probability of experiencing diarrhea (OR 3.94, P = 0.004) and hand-foot syndrome (OR 10.89, P = 0.004) was significantly higher in the capecitabine group, attributable to the drug characteristics. Conversely, the likelihood of developing neutropenia (OR 0.50, P = 0.03) was higher in the anthracycline group. CONCLUSIONS According to the current evidence, there was no statistically significant difference in the primary outcomes when capecitabine was substituted for anthracycline drugs. Thus, capecitabine can be regarded as a feasible alternative in the subset of patients who necessitate the exclusion of anthracyclines.

Abstract
In primates, foveal and peripheral vision have distinct neural architectures and functions. However, it has been debated if selective attention operates via the same or different neural mechanisms across eccentricities. We tested these alternative accounts by examining the effects of selective attention on the steady-state visually evoked potential (SSVEP) and the fronto-parietal signal measured via EEG from human subjects performing a sustained visuospatial attention task. With a negligible level of eye movements, both SSVEP and SND exhibited the heterogeneous patterns of attentional modulations across eccentricities. Specifically, the attentional modulations of these signals peaked at the parafoveal locations and such modulations wore off as visual stimuli appeared closer to the fovea or further away towards the periphery. However, with a relatively higher level of eye movements, the heterogeneous patterns of attentional modulations of these neural signals were less robust. These data demonstrate that the top-down influence of covert visuospatial attention on early sensory processing in human cortex depends on eccentricity and the level of saccadic responses. Taken together, the results suggest that sustained visuospatial attention operates differently across different eccentric locations, providing new understanding of how attention augments sensory representations regardless of where the attended stimulus appears.

Abstract
To stabilize and transport them through complex systems, nanoparticles are often encapsulated in polymeric nanocarriers, which are tailored to specific environments. For example, a hydrophilic polymer capsule maintains the circulation and stability of nanoparticles in aqueous environments. A more highly designed nanocarrier might have a hydrophobic core and a hydrophilic shell to allow the transport of hydrophobic nanoparticles and pharmaceuticals through physiological media. Polydimethylsiloxane, PDMS, is a hydrophobic material in a liquid-like state at room temperature. The preparation of stable, aqueous dispersions of PDMS droplets in water is problematic due to the intense mismatch in surface energies between PDMS and water. The present work describes the encapsulation of hydrophobic metal and metal oxide nanoparticles within PDMS nanodroplets using flash nanoprecipitation. The PDMS is terminated by amino groups, and the nanodroplet is capped with a layer of poly(styrenesulfonate), forming a glassy outer shell. The hydrophobic nanoparticles nucleate PDMS droplet formation, decreasing the droplet size. The resulting nanocomposite nanodroplets are stable in aqueous salt solutions without the use of surfactants. The hierarchical structuring, elucidated with small-angle X-ray scattering, offers a new platform for the isolation and transport of hydrophobic molecules and nanoparticles through aqueous systems.

Abstract
Principal component analysis (PCA) is a typical unsupervised dimensionality reduction algorithm, and one of its important weaknesses is that the squared l2 -norm cannot overcome the influence of outliers. Existing robust PCA methods based on paradigm have the following two drawbacks. First, the objective function of PCA based on the l1 -norm has no rotational invariance and limited robustness to outliers, and its solution mostly uses a greedy search strategy, which is expensive. Second, the robust PCA based on the l2,1 -norm and the l2,p -norm is essential to learn probability weights for data, which only weakens the influence of outliers on the learning projection matrix and cannot be completely eliminated. Moreover, the ability to detect anomalies is also very poor. To solve these problems, we propose a novel discrete robust principal component analysis (DRPCA). Through self-learning binary weights, the influence of outliers on the projection matrix and data center estimation can be completely eliminated, and anomaly detection can be directly performed. In addition, an alternating iterative optimization algorithm is designed to solve the proposed problem and realize the automatic update of binary weights. Finally, our proposed model is successfully applied to anomaly detection applications, and experimental results demonstrate that the superiority of our proposed method compared with the state-of-the-art methods.

Abstract
Low-density lipoprotein (LDL), especially oxidative modified LDL (Ox-LDL), is the key risk factor for plaque accumulation and the development of cardiovascular disease. Herein, a highly specific Ox-LDL-triggered fluorogenic-colorimetric probe Pro-P1 is developed for visualizing the oxidation and aggregation progress of lipoproteins and plaque. A series of green fluorescent protein chromophores with modified donor-acceptor structures, containing carbazole as an electron donor and various substituents including pyridine-vinyl (P1), phenol-vinyl (P2), N, N-dimethylaniline-vinyl (P3), and thiophene-vinyl (P4), have been synthesized and evaluated. Emission spectroscopy and theoretical calculations of P1-P4 indicate that P1 shows enhanced green fluorescence (λem = 560 nm) by inhibiting its twisted intramolecular charge transfer in the presence of Ox-LDL. This feature allows the selection of P1 as a sensitive probe to directly visualize ferroptosis and Cu2+ -mediated LDL oxidative aggregation via in situ formation of fluorophore-bound Ox-LDL in living cells. The red-emissive probe Pro-P1 (λem = 660 nm) is prepared via borate protection of P1, which can be cleaved into P1 under high expression of HOCl and Ox-LDL condition at the lesion site, resulting in enhanced green emission. The plaque area and size with clear boundaries can be delineated by colorimetric fluorescence imaging and fluorescence lifetime imaging with precise differentiation.

Abstract
N6-methyladenosine (m6A) maintains maternal RNA stability in oocytes. One regulator of m6A, ALKBH5, reverses m6A deposition and is essential in RNA metabolism. However, the specific role of ALKBH5 in oocyte maturation remains elusive. Here, we show that Alkbh5 depletion causes a wide range of defects in oocyte meiosis and results in female infertility. Temporal profiling of the maternal transcriptomes revealed striking RNA accumulation in Alkbh5-/- oocytes during meiotic maturation. Analysis of m6A dynamics demonstrated that ALKBH5-mediated m6A demethylation ensures the timely degradation of maternal RNAs, which is severely disrupted following Alkbh5-/- depletion. A distinct subset of transcripts with persistent m6A peaks are recognized by the m6A reader IGF2BP2 and thus remain stabilized, resulting in impaired RNA clearance. Additionally, reducing IGF2BP2 in Alkbh5-depleted oocytes partially rescued these defects. Overall, this work identifies ALKBH5 as a key determinant of oocyte quality and unveil the facilitating role of ALKBH5-mediated m6A removal in maternal RNA decay.

Abstract
Vinyl-functionalized graphene oxide (VGO) was used as a reactive compatibilizer to prepare poly(lactic acid)/polybutylene adipate-co-terephthalate (PLA/PBAT) blends. The linear rheological and scanning electron microscopy results confirmed that the VGO nanosheets were quite efficient in compatibilizing PLA/PBAT blends. The size of the PBAT dispersed phase was remarkably decreased in the presence of VGO nanosheets. Moreover, the VGO nanosheets exhibited strong nucleating effects on the crystallization process of PLA. The crystallinity of PLA component in the compatibilized blend with various VGO nanosheets was higher than 40%, upon the cooling rate of 20 °C/min. The prepared PLA/PBAT pellets were applied to 3D printing, using a self-developed screw-based 3D printer. The results showed that all the prepared PLA/PBAT blend pellets can be 3D printed successfully. The notched Izod impact test results showed that, in the presence of VGO, an increase of at least 142% in impact strength was achieved for PLA/PBAT blend. This could be attributed to the compatibilizing effect of the VGO nanosheets. Thus, this work provides a novel way to prepare tough PLA-based materials for 3D printing.

Abstract
CDK4/6 inhibitors have become the standard of care for HR-positive, HER2-negative advanced breast cancer. However, there is still a lack of standard recommendations for the subsequent treatment of patients with CDK4/6 inhibitor resistance, especially those with primary resistance or rapid progression. Currently, appropriate treatment strategies included re-challenge of CDK4/6 inhibitors, combination with PI3K/AKT/mTOR inhibitors, new antibody drug conjugate (ADC), novel endocrine therapy drugs, and chemotherapy. In addition, many new targeted drugs and new combination treatment strategies are also being explored. In the future, precise treatment strategies based on biomarkers should be established, as well as the optimal sequence of use of different therapies.

Abstract
Objective: To examine the association between smoking status and related mortality among elderly people aged 60 and above in urban and rural areas of Beijing City. Methods: Based on Beijing City Elderly Comprehensive Health Cohort Study from 2009 to 2014, a total of 4 499 eligible older adults included in the baseline survey were followed up and investigated to collect information on survival and death. The Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs), and the dose-response relationship was estimated between the smoking index, the years of quitting and mortality. Results: The median (IQR) age of 4 499 subjects was 70.00 (10.00) years old, including 1 814 (40.32%) males. The proportion of non-smokers, former smokers and current smokers was 69.50% (3 127/4 499), 13.20% (594/4 499) and 17.30% (778/4 499), respectively. After adjusting for confounding factors such as demographic and sociological characteristics, lifestyle, etc., the results of multivariate Cox regression analysis showed that, compared to non-smokers, former smokers had a 30.6% increased risk of all-cause mortality [HR (95%CI): 1.306 (1.043-1.636)] and the HR (95%CI) of all-cause, malignant tumor and lung cancer mortality among current smokers has increased by 50.0% [HR (95%CI): 1.500 (1.199-1.877)], 80.3% [HR (95%CI): 1.803 (1.226-2.652)] and 212.6% [HR (95%CI): 3.126 (1.626-6.012)], respectively. The smoking index was positively associated with the increased risk of all-cause, malignant tumor and lung cancer mortality, while the years of smoking cessation were negatively associated with that risk (P<0.05). Conclusion: Smoking is associated with tobacco-related mortality among elderly people in Beijing City.

Abstract
Individuals generally form their unique memories from shared experiences, yet the neural representational mechanisms underlying this subjectiveness of memory are poorly understood. The current study addressed this important question from the cross-subject neural representational perspective, leveraging a large functional magnetic resonance imaging dataset (n = 415) of a face-name associative memory task. We found that individuals' memory abilities were predicted by their synchronization to the group-averaged, canonical trial-by-trial activation level and, to a lesser degree, by their similarity to the group-averaged representational patterns during encoding. More importantly, the memory content shared between pairs of participants could be predicted by their shared local neural activation pattern, particularly in the angular gyrus and ventromedial prefrontal cortex, even after controlling for differences in memory abilities. These results uncover neural representational mechanisms for individualized memory and underscore the constructive nature of episodic memory.

Abstract
Objective: To systematically evaluate the efficacy and safety of new systemic therapies (biological agents and JAK inhibitors) in moderate-to-severe elderly atopic dermatitis. Methods: The database of Embase, PubMed, Web of Science,Cochrane, the Global Resource of Eczema Trials database, ClinicalTrials. Gov, CNKI, Wanfang, VIP were used to search for literatures of randomized controlled trials (RCTs) and real-world studies of the treatment of moderate-to-severe AD with the new systemic therapies from January 2014 to February 2023. Two reviewers independently screened the literature, extracted the data and evaluated the risk of bias included in the study. Data were analyzed by Review Manager 5.3 software for meta-analysis and odds ratio (OR) and 95% confidence interval were used as the effect statistics. The heterogeneity and publication bias were assessed. Results: A total of five studies (523 elderly patients and 802 young patients) using dupilumab were included for meta-analysis. Dupilumab showed good efficacy in elderly AD, with 74.6%(390/523) of patients whose EASI reached 75, which there was no significant difference with young patients (OR=0.79, 95%CI:0.58-1.07, P=0.122); the proportion of elderly patients with NRS improvement≥4 was 68.7%(244/355), and there was no significant difference with young patients (OR=0.79, 95%CI:0.55-1.14, P=0.213). The most common adverse reactions were conjunctivitis, facial and neck erythema and injection site reactions, and there are no serious adverse events in both groups. The incidence of adverse events in elderly patients was 24.3%(65/267), which was not significantly different from that in young patients (OR=1.07, 95%CI:0.65-1.77, P=0.789). There are few studies on other biological agents and JAK inhibitors in elderly AD patients. We only found 4 studies of elderly AD patients using JAK inhibitors (2 studies on abrocitinib and 2 studies on upadacitinib). The clinical efficacy of abrocitinib in the elderly was not significantly different from that in the young. The incidence of serious adverse events of abrocitinib and upadacitinib increased in the elderly and was dose-related. Conclusion: The efficacy and safety of dupilumab in elderly AD patients were similar to those in the young patients, and the JAK inhibitor needs to be further studied and verified.

Abstract
Objective: To evaluate the effect of compound chamomile and lidocaine hydrochloride gel on oropharyngeal complications after the use of laryngeal mask airway with positive pressure ventilation. Methods: A total of 64 patients undergoing elective surgery under general anesthesia using laryngeal mask airway (LMA) with positive pressure ventilation in Beijing Tongren Hospital Affiliated to Capital Medical University From January to March 2023 were prospectively selected and divided into two groups by the random number table method: normal saline group (n=32), with 18 males and 14 females, aged 28-64 (48.4±10.6) years, and the compound chamomile and lidocaine hydrochloride gel group (chamomile gel group, n=32), with 18 males and 14 females, aged 24-64 (46.3±10.8) years. Patients in both groups received total intravenous anesthesia. Before LMA placement, the front, shoulder and back of LMA were lubricated with normal saline and compound chamomile and lidocaine hydrochloride gel in the normal saline group and the chamomile gel group, respectively. The main outcome measure was the incidence of postoperative oropharyngeal mucosal inflammation at different time points after the removal of the laryngeal mask. Secondary outcome measures included oropharyngeal mucositis score, sore throat score, hoarse voice score, cough score and throat dryness score at different time points after LMA removal, the number of LMA insertion times, time of successful insertion and leakage pressure, as well as stress reactions such as cough and agitation before and after LMA removal, and adverse reactions such as tongue numbness and protective pharyngeal reflex limitation during recovery. Results: The incidence of oropharyngeal mucositis in the chamomile gel group was 25.0% (8/32), 31.3% (10/32), 28.1% (9/32) and 3.1% (1/32) at 0.5, 3, 6 and 24 h after LMA removal, respectively, which were lower than those of normal saline group [53.1% (17/32), 59.4% (19/32), 59.4% (19/32) and 21.9% (7/32)] (all P<0.05). The oropharyngeal mucositis scores of patients in the chamomile gel group were 0 (0, 0.8), 0 (0, 1.0), 0 (0, 1.0) and 0 (0, 0) respectively at 0.5, 3, 6 and 24 h after LMA removal, which were lower than those in the saline group [1.0 (1.0, 1.8), 1.0 (0, 2.0), 1.0 (0, 2.0) and 0 (0, 0)] (all P<0.05). The cough score of the patients in the chamomile gel group was 0 (0, 0) and 0 (0, 0) at 3, 6 h after LMA removal, which were lower than those of the normal saline group [(0, 0) and 0 (0, 0)] (both P<0.05). The throat dryness score of the patients in the chamomile gel group was 0 (0, 1.0) at 3 h after LMA removal, which was lower than that of the normal saline group [1.0 (0.3, 1.0)] (P=0.019). The time of successful LMA insertion in the chamomile gel group was 25.0 (20.3, 29.8) s, which was shorter than that in the saline group [29.0 (25.0, 32.0) s] (P=0.016). There were no significant differences in the number of LMA insertion, leakage pressure, postoperative sore throat and hoarse voice scores between the two groups (all P>0.05). Likewise, there were no stress reactions such as cough and agitation before and after LMA removal, and no adverse reactions such as tongue numbness and limited protective pharyngeal reflex during recovery. Conclusion: Compound chamomile and hydrochloride lidocaine gel can reduce the incidence of postoperative oropharyngeal mucositis, relieve the symptoms of postoperative oropharyngeal mucositis, pharyngeal dryness and cough, and improve the postoperative comfort of patients using the laryngeal mask airway with positive pressure ventilation.

Abstract
Objective: To investigate the distribution characteristics of sex hormones and their relationship with all-cause mortality in Hainan female centenarians. Methods: All the subjects were from China Hainan Centenarian Cohort Study. A total of 717 female centenarians were included in the final analysis. Kaplan-Meier method was used to draw the survival curve, and Cox proportional hazard regression was used to analyze the relationship between sex hormones and survival time. Results: The M(Q1, Q3) of estradiol and progesterone among female centenarians was 32.60 (18.40, 58.70) pmol/L and 0.62 (0.32, 1.01) nmol/L. The estradiol (pmol/L) and progesterone (nmol/L) in the survival and death groups were 26.65 vs.37.80, 0.54 vs.0.69, respectively, with statistical differences (P<0.05). Cox multivariate analysis showed that estradiol and progesterone were significantly associated with death (P<0.05), the hazard ratio (HR) of estradiol Q4 was 1.58 (95%CI: 1.17-2.15), and the HR of progesterone Q3 was 1.53 (95%CI: 1.10-2.12), HR for Q4 was 1.63 (95%CI: 1.15-2.32). Subgroup and cross-analysis showed that estradiol was statistically significant with hypertension, diabetes, and low high-density lipoprotein cholesterol (P<0.05), and progesterone interacted with diabetes (P=0.016), while testosterone interacted with low high-density lipoprotein cholesterol (P=0.034). Conclusion: It is suggested that the estrogen levels of female centenarians in Hainan were associated with a higher mortality risk and an increased risk of cardiovascular metabolic disease (such as diabetes, hypertension, and abnormal lipid metabolism).

Abstract
Objective: To explore the impact of a new type of modified nasopharynx airway preserving spontaneous breathing under general anesthesia on the postoperative recovery quality of patients undergoing hysteroscopic daytime surgery. Methods: A total of 80 patients undergoing hysteroscopic daytime surgery at Beijing Tongren Hospital from August to December 2022 was prospectively selected. The patients were randomly divided into two groups using a random number table method: patients in the laryngeal mask mechanical ventilation general anesthesia group (laryngeal mask group, n=40) aged (46.8±10.1) years (20-65 years), while patients in the modified nasopharyngeal airway preserving spontaneous breathing general anesthesia group (nasopharyngeal airway group, n=40) aged (45.5±12.1) years (26-65 years). The main outcome measures were the clinical recovery score (CRS) and modified alertness and sedation score (MOAA/S) of patients at different postoperative time points. Secondary observation indicators included anesthesia induction time, awakening time, and extubation time, changes of hemodynamic indicators between preoperative and intraoperative period, and incidence of adverse reactions during and after surgery. Results: The CRS scores [M (Q1, Q3)] of patients in the nasopharyngeal airway group were 8 (8, 9), 8 (8, 9), 8 (8, 9), 9 (9, 9) and 10 (10, 11) at postoperative awakening, immediately after extubation, 5 minutes after extubation, 15 minutes after extubation, and 30 minutes after extubation, respectively, which were higher than those in the laryngeal mask group [7 (6, 8), 7 (7, 8), 7 (7, 8), 8 (8, 8) and 9 (8, 9)] (all P<0.001). The MOAA/S scores of the nasopharyngeal airway group were 5 (5, 5), 5 (5, 5), 5 (5, 5) and 5 (5, 5) at postoperative awakening, immediately after extubation, 5 minutes after extubation, and 15 minutes after extubation, respectively, which were higher than those in the laryngeal mask group [4 (3, 5), 4 (4, 5), 5 (5, 5) and 5 (5, 5)] (all P<0.05). The anesthesia induction time, awakening time, and extubation time of the nasopharyngeal airway group were (47.8±4.3) s, (4.1±1.7) min and (4.5±1.7) min, respectively, which were shorter than those of laryngeal mask group [(138.8±4.2) s, (7.2±2.9) min and (8.1±2.7) min] (all P<0.05). The mean arterial pressure (MAP) of patients in the nasopharynx airway group during extubation was (84.9±10.2) mmHg (1 mmHg=0.133 kPa), which was lower than that of the laryngeal mask group [(93.2±7.5) mmHg] (P<0.05). The partial pressure of end-tidal carbon dioxide (PetCO2) during cervical dilation was (22.0±5.9) mmHg, which was lower than those of the laryngeal mask group [(37.2±2.2) mmHg] (P<0.05). The PetCO2 during intrauterine operation and extubation were (45.5±6.7) and (41.6±4.5) mmHg, which were higher than those of the laryngeal mask group [(39.2±4.1) mmHg and (38.6±3.6) mmHg] (both P<0.05). The incidence of respiratory depression and body movement during surgery in the nasopharyngeal airway group were 27.5% (11/40) and 17.5% (7/40), respectively, which were higher than those in the laryngeal mask group [0 and 0] (both P<0.05). The incidence of postoperative drowsiness was 2.5% (1/40), which was lower than that of the laryngeal mask group [17.5% (7/40)] (P<0.05). There was no severe physical activity or intraoperative awareness in the two groups. Conclusion: The new modified general anesthesia method of preserving spontaneous breathing through the nasopharynx airway can improve the postoperative recovery quality of patients, and reduce the occurrence of adverse reactions, which facilitates rapid recovery after hysteroscopic daytime surgery.

Abstract
Objective: To evaluate the preventive effect of atropine premedication during anesthesia induction on vagal reflex in patients undergoing suspension laryngoscopy. Methods: A total of 342 patients (202 males and 140 females) scheduled for suspension laryngoscopy under general anesthesia in Beijing Tongren Hospital from October 2021 to March 2022 were prospectively enrolled, with a mean age of (48.1±11.9) years. The patients were randomly divided into two groups using the random number table method: the treatment group (n=171) and the control group (n=171). Patients in the treatment group were administrated with 0.5 mg atropine intravenously guttae (ivgtt) while patients in the control group were given equivalent volume of normal saline. For all patients, if heart rate (HR)<50 beats/min happened during the insertion of the suspension laryngoscope, the operation should be stopped and the laryngoscope should be removed. Patients without HR recovery after the removal of the laryngoscope should be given 0.5 mg atropine, and the operation should be continued after the HR recovered. The primary outcome was the incidence of HR fluctuation over 20% (ΔHR>20%) before and immediately after suspension laryngoscope fixation, and the secondary outcomes included HR, mean arterial pressure (MAP) of the two groups recorded before and after anesthesia induction, before and immediately after suspension laryngoscope fixation, and the incidences of sinus bradycardia, laryngoscope removal and atropine treatment during operation. Results: The incidences of ΔHR>20% and bradycardia immediately after the suspension laryngoscope fixation were 14.6% (25/171) and 12.9% (22/171) in the treatment group, which were significantly lower than those in the control group [28.1% (48/171) and 29.8% (51/171)] (both P<0.05). The HR immediately after the suspension laryngoscope fixation in the treatment group [(66.4±13.5) beats/min] and in the control group [(60.8±15.7) beats/min] was significantly lower than those before the suspension laryngoscope fixation [(74.7±11.1) beats/min and (67.6±12.8) beats/min, respectively] (both P<0.05). There were no significant differences in MAP between the two groups at each time point (all P>0.05). The incidence of laryngoscope removal once plus 0.5 mg atropine administration, laryngoscope removal twice plus 0.5 mg atropine administration and laryngoscope removal twice plus 1.0 mg atropine administration was 9.9% (17/171), 1.8% (3/171) and 0 (0) in the treatment group, respectively, which was significantly lower than those in the control group [24.0% (41/171), 5.8% (10/171) and 2.3% (4/171), respectively] (all P<0.05). Conclusion: Atropine premedication during anesthesia induction can effectively reduce the occurrence of vagal reflex in patients undergoing suspension laryngoscopy.

Abstract
AIMS The association between serum albumin and depressive symptoms has been unclear in previous epidemiological studies. We explored whether serum albumin is associated with depressive symptoms based on the National Health and Nutrition Examination Survey (NHANES) data. METHODS This cross-sectional study included 13,681 participants aged ≥ 20 years from the NHANES performed during 2005-2018, which produced nationally representative database. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Serum albumin concentration was measured using the bromocresol purple dye method, and participants were divided into quartiles of serum albumin concentrations. Weighted data were calculated according to analytical guidelines. Logistics regression and linear regression models were used to assess and quantify the association between serum albumin and depressive symptoms. Univariate and stratified analyses were also performed. RESULTS There were 1551 (10.23%) adults (aged ≥ 20 years) with depressive symptoms among the 13,681. A negative association was found between serum albumin concentration and depressive symptoms. Compared with the lowest albumin quartile, the multivariate-adjusted effect size (95% confidence interval) for depressive symptoms of the fully adjusted model in the highest albumin quartile was 0.77 (0.60 to 0.99) and - 0.38 (- 0.66 to - 0.09) using logistics regression and linear regression models respectively. Current smoking status modified the association between serum albumin concentration and PHQ-9 scores (p for interaction = 0.033). CONCLUSION This cross-sectional study revealed that albumin concentration is significantly more likely to be a protective factor for depressive symptoms, with the association being more pronounced in non-smokers.

Abstract
Introduction The combination of a PD-L1 inhibitor plus carboplatin/cisplatin and etoposide (EC/EP) has become a new standard first-line treatment for extensive-stage small-cell lung cancer (ES-SCLC). Combining concurrent palliative hypofractionated radiotherapy of the thorax (HFRT) and immunochemotherapy may have a synergistic effect. In this study, we explored an optimal model of combination radiotherapy with immunochemotherapy as first-line treatment of ES-SCLC. Patients and methods In this multicenter single-arm phase 2 trial, patients with ES-SCLC received atezolizumab with EC/EP for two cycles (induction phase), then, those who did not progress received concurrent palliative HFRT and two cycles of atezolizumab with EC/EP (combination phase). Afterward they received atezolizumab every 3 weeks for a maximum of 2 years after study enrolment (maintenance phase). Prophylactic cranial irradiation (PCI) was recommended. The primary endpoints were safety and tolerance; the second endpoints were progression-free survival (PFS). Results Forty patients were enrolled, and all had completed palliative HFRT and four cycles of immunochemotherapy. There were seven grade 3 adverse events (3 decreased neutrophil count, 1 anemia, 2 pneumonitis, 1 esoenteritis), two grade 4 adverse events (2 decreased white cell count) and no grade 5 toxicities. The pneumonitis rate was 12.5% (three grade 2 and two grade 3 events). At the median follow-up of 14.2 months (range, 6.8-28.7), the median PFS was 8.6 months (95%CI, 6.1-11.1). Conclusion The addition of concurrent hypofractionated thoracic radiotherapy to first-line immunochemotherapy for ES-SCLC was well tolerated and showed promising clinical efficacy. Additional randomized trials are needed to validate benefits. Clinical trial registration https://clinicaltrials.gov/ (NCT04636762).

Abstract
Learning statistical regularities of target objects speeds visual search performance. However, we do not yet know whether this statistical learning effect is driven by biasing attentional selection at the early perceptual stage of processing, as theories of attention propose, or by improving the decision-making efficiency at a late response-related stage. Leveraging the high-temporal resolution of the event-related potential (ERP) technique, we had 16 human observers perform a visual search task where we inserted a fine-grained statistical regularity that the target shapes appeared in different colors with six unique probabilities. Observers unintentionally learned these regularities such that they were faster to report targets that appeared in more likely target colors. The observers' ERPs showed that this learning effect resulted in subjects making faster decisions about the target presence, and not by preferentially shifting attention to more rapidly select likely target colors, as is often assumed by the attentional selection account, supporting a post-selection account for statistical learning of the probabilistic regularities of target features. These results provide fundamental insights into the attentional control mechanisms of statistical learning. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
OBJECTIVE This study's objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. METHODS Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. RESULTS The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%-79.0%), 75.0% (95% CI: 64.1%-83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. CONCLUSION PMTS is safe and effective in improving insomnia disorders.

Abstract
Ferroptosis was reported to be involved in cerebral ischemia-reperfusion injury (CIRI), on which the effects of berberine (BBR) remain unclear. Moreover, based on the critical role of gut microbiota in pleiotropic actions of BBR, we hypothesized that BBR can suppress CIRI-induced ferroptosis by modulating the gut microbiota. In this study, the results showed that BBR obviously attenuated the behavioral deficits of CIRI mice, accompanied with the improved survival rate and neuron damages, as phenocopied by dirty cage experiment. The typical morphological changes in ferroptotic cells and biomarkers of ferroptosis were attenuated in BBR- and its fecal microbiota-treated mice, accompanied by reduced malondialdehyde and reactive oxygen species, and the increased glutathione (GSH). BBR was found to alter the gut microbiota of CIRI mice with decreased abundance of Muribaculaceae, Erysipelotrichaceae, Helicobacteraceae, Streptococcaceae and Tannerellaceae, but elevated Bacteroidaceae and Enterobacteriaceae. KEGG analysis based on the 16S rRNA results indicated that multiple metabolic pathways including ferroptosis and GSH metabolism, were altered by BBR. Oppositely, the antibiotics administration counteracted the protective properties of BBR. Summarily, this study revealed the therapeutic potential of BBR on CIRI via inhibiting neuronal ferroptosis, in which upregulated glutathione peroxidase 1 (GPX1) was possibly involved. Moreover, the BBR-modulated gut microbiota was shown to play the critical role in the underlying mechanism.

Abstract
Background Breast and thyroid cancer are increasingly prevalent, but it remains unclear whether the observed associations are due to heightened medical surveillance or intrinsic etiological factors. Observational studies are vulnerable to residual confounding, reverse causality, and bias, which can compromise causal inference. In this study, we employed a two-sample Mendelian randomization (MR) analysis to establish a causal link between breast cancer and heightened thyroid cancer risk. Methods We obtained the single nucleotide polymorphisms (SNPs) associated with breast cancer from a genome-wide association study (GWAS) conducted by the Breast Cancer Association Consortium (BCAC). The FinnGen consortium's latest and largest accessible GWAS thyroid cancer data at the summary level. We performed four MR analyses, including the inverse-variance-weighted (IVW), weighted median, MR-Egger regression, and weighted mode, to evaluate the potential causal connection between genetically predicted breast cancer and higher risk for thyroid cancer. Sensitivity analysis, heterogeneity and pleiotropy tests were used to ensure the reliability of our findings. Results Our study revealed causal relationship between genetically predicted breast cancer and thyroid cancer (IVW method, odds ratio (OR) = 1.135, 95% confidence interval (CI): 1.006 to 1.279, P = 0.038). However, there was no causal association between genetically predicted triple-negative breast cancer and thyroid cancer (OR = 0.817, 95% CI: 0.610 to 1.095, P = 0.177). There was no directional pleiotropy or horizontal pleiotropy in the present study. Conclusion This two-sample MR study supports a causal link between ER-positive breast cancer and heightened the risk of thyroid cancer. Our analysis did not reveal a direct correlation between triple-negative breast cancer and thyroid cancer.

Abstract
Background Recently, sexually transmitted diseases (STDs) remain a sensitive issue within generally healthy environments. Different countries have developed various principle-based approaches to tackle the ethical issues surrounding STDs. Due to lacking any relevant laws or code of conducts to deal with the ethical issue, it has become a notable ethical problem in China. Objective Ethical principles involve a sensitive clinical problem, this paper intends to reflect upon and discuss how nurses as moral agents deal with ethical dilemmas within Chinese culture and provided some orientations for further study. Methods This paper briefly presented the nurses' ethical dilemma related to the issue of confidentiality and disclosure of STD patients' information via a case scenario. Based on Chinese cultural tradition, we focused on how to solve this situation as a clinical nurse with ethical principles and philosophical theories. The process of discussion provided eight steps by the Corey et al model to solve the ethical dilemma. Conclusion The ability to deal with ethical dilemmas is a necessary quality for nurses. On the one hand, nurses should respect patients' autonomy and contribute positively to the relationship between confidentiality and the nurse-patient therapeutic relationship. On the other hand, nurses should combine with the current situation and make a targeted decision where necessary. Of course, professional code supported by related policies is necessary.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Blood-activating and stasis-transforming traditional Chinese medicines (BAST) are a class of herbs that have the effect of dilating blood vessels and dispersing stagnation. Modern pharmaceutical research has demonstrated that they are capable of improving hemodynamics and micro-flow, resist thrombosis and promote blood flow. BAST contain numerous active ingredients, which can theoretically regulate multiple targets at the same time and have a wide range of pharmacological effects in the treatment of diseases including human cancers. Clinically, BAST have minimal side effects and can be used in combination with Western medicine to improve patients' quality of life, lessen adverse effects and minimize the risk of recurrence and metastasis of cancers. AIM OF THE REVIEW We aimed to summarize the research progression of BAST on lung cancer in the past five years and present a prospect for the future. Particularly, this review further analyzes the effects and molecular mechanisms that BAST inhibit the invasion and metastasis of lung cancer. MATERIALS AND METHODS Relevant studies about BSAT were collected from PubMed and Web of science. RESULTS Lung cancer is one of the malignant tumors with the highest mortality rate. Most patients with lung cancer are diagnosed at an advanced stage and are highly susceptible to metastasis. Recent studies have shown that BAST, a class of traditional Chinese medicine (TCM) with the function of opening veins and dispersing blood stasis, significantly improve hemodynamics and microcirculation, prevent thrombosis and promote blood flow, and thereby inhibiting the invasion and metastasis of lung cancer. In the current review, we analyzed 51 active ingredients extracted from BAST. It was found that BAST and their active ingredients contribute to the prevention of invasion and metastasis of lung cancer through multiple mechanisms, such as regulation of EMT process, specific signaling pathway and metastasis-related genes, tumor blood vessel formation, immune microenvironment and inflammatory response of tumors. CONCLUSIONS BSAT and its active ingredients have showed promising anticancer activity and significantly inhibit the invasion and metastasis of lung cancer. A growing number of studies have realized their potential clinical significance in the therapy of lung cancer, which will provide substantial evidences for the development of new TCM for lung cancer therapy.

Abstract
Dissolved oxygen (O2) and hydrogen sulfide (H2S) are two important indicators of water quality, their levels are of intimate dependence and varying over time. It is of great significance to monitoring of dissolved O2 and H2S simultaneously in natural water, yet has not been reported because of lack of effective approaches. In this work, a portable electrochemical microsensor was developed for simultaneously quantifying dissolved O2 and H2S. Here, Pd@Ni nanoparticles (NPs) were self-assembled onto the microelectrode by MXene titanium carbide (Ti3C2Tx), which were of responsibility towards O2 and H2S detection within single electrochemical reduction process. On this regard, Pd NPs facilitated catalyzing the electrochemical reduction of O2, while Ni NPs were employed as recognition element for H2S detection. With the electrochemical reduction sweep, the initial application of a positive voltage rendered the Ni to be oxidized to be Ni ions, contributing to their following capture of surrounding S2- to form nickel sulfide. Nickel sulfide with highly electrochemical activity were capable of generating detecting reduction current. In consequence, the as-designed microsensor can simultaneously determine O2 concentrations ranging from 36 to 318 μM and H2S levels ranging from 0.1 to 2.5 μM with high selectivity. Finally, the portable microsensor was successfully applied to simultaneous detection dissolved O2 and H2S in natural water in-site, the results of which were comparable to the classical methods.

Abstract
Objective: To investigate the risk factors and treatment outcome of persistent inflammation-immunosuppression-catabolism syndrome (PICS) in patients with extensive burns. Methods: A retrospective case series study was conducted. From January 2017 to December 2021, 220 patients with extensive burns who were admitted to Guangzhou Red Cross Hospital of Jinan University met the inclusion criteria, including 168 males and 52 females, aged 18-84 (43±14) years. According to the occurrence of PICS, the patients were divided into PICS group (84 patients) and non-PICS group (136 patients). The general data such as sex, age, complication of underlying diseases and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on admission, sepsis-related organ failure evaluation (SOFA) scores on admission and 14 days post admission, and proportion of patients with mechanical ventilation over 48 h during treatment, special conditions such as total burn area, full-thickness burn area, proportion of patients admitted within 48 h post injury, and exposed deep wound area at the 30th day post injury, outcome indicators such as hospitalization day, total cost of hospital stay, number of surgeries, and death of patients in the 2 groups were collected and analyzed. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. The multivariate logistic regression analysis was performed on the indicators with statistically significant differences between the two groups except for outcome indicators, and the independent risk factors influencing secondary PICS in patients with extensive burns were screened. Results: The APACHE Ⅱ and SOFA scores on admission, and proportion of patients with mechanical ventilation over 48 h during treatment of patients in PICS group were significantly higher than those in non-PICS group (t=6.78, Z=-4.75, χ2=4.74, respectively, P<0.05). There were no statistically significant differences in the rest of general data of patients between the two groups (P>0.05). The total burn area, full-thickness burn area, and exposed deep wound area at the 30th day post injury in PICS group were significantly greater than those in non-PICS group (t=6.29, Z=-7.25, Z=-8.73, P<0.05), the exposed deep wound areas at the 30th day post injury in PICS group and non-PICS group were respectively 25% (15%, 35%) total body surface area (TBSA) and 8% (0, 13%) TBSA, while the proportion of patients admitted within 48 h post injury was significantly lower than that in non-PICS group (χ2=6.13, P<0.05). The hospitalization day, total cost of hospital stay, and number of surgeries of patients in PICS group were significantly higher than those in non-PICS group (with Z values of -7.12, -8.48, and -6.87, respectively, P<0.05), while the deaths of patients in the 2 groups were similar (P>0.05). The APACHE Ⅱ score on admission and exposed deep wound area at the 30th day post injury both were the independent risk factors for PICS in patients with extensive burns (with odds ratios of 1.15 and 1.07, 95% confidence intervals of 1.06-1.25 and 1.05-1.10, respectively, P<0.05). Conclusions: The APACHE Ⅱ score on admission and exposed deep wound area at the 30th day post injury are the independent risk factors for PICS in patients with extensive burns. The patients with secondary PICS had good prognosis with more surgical intervention and hospitalization day, and higher total cost of hospital stay.

Abstract
BACKGROUND Ethanol-induced gastric mucosal lesions (EGML) is one of the most common digestive disorders for which current therapies have limited outcomes in clinical practice. Prevotella histicola (P. histicola) has shown probiotic efficacy against arthritis, multiple sclerosis and oestrogen deficiency-induced depression in mice; however, its role in EGML remains unclear in spite of its extensive colonisation of the stomach. Ferroptosis, which is characterised by lipid peroxidation, may be involved in EGML. Herein, we aimed to investigate the effects and underlying mechanism of action of P. histicola on EGML in the ferroptosis-dependent pathway. METHODS P. histicola was intragastrically administered for a week, and deferoxamine (DFO), a ferroptosis inhibitor, was intraperitoneally injected prior to oral ethanol administration. The gastric mucosal lesions and ferroptosis were assessed via histopathological examinations, quantitative real-time PCR, Western blot, immunohistochemistry and immunofluorescence. RESULTS P. histicola was originally found to attenuate EGML by reducing histopathological changes and lipid reactive oxygen species (ROS) accumulation. The pro-ferroptotic genes of Transferrin Receptor (TFR1), Solute Carrier Family 39 Member 14 (SLC39A14), Haem Oxygenase-1 (HMOX-1), Acyl-CoA Synthetase Long-chain Family Member 4 (ACSL4), Cyclooxygenase 2 (COX-2) and mitochondrial Voltage-dependent Anion Channels (VDACs) were up-regulated; the anti-ferroptotic System Xc-/Glutathione Peroxidase 4 (GPX4) axis was inhibited after ethanol administration. However, the changes of histopathology and ferroptosis-related parameters induced by ethanol were reversed by DFO. Furthermore, P. histicola treatment significantly downregulated the expression of ACSL4, HMOX-1 and COX-2, as well as TFR1 and SLC39A14, on mRNA or the protein level, while activating the System Xc-/GPX4 axis. CONCLUSIONS We found that P. histicola reduces ferroptosis to attenuate EGML by inhibiting the ACSL4- and VDAC-dependent pro-ferroptotic pathways and activating the anti-ferroptotic System Xc-/GPX4 axis.

Abstract
The Artemisia argyi Lévl. et Van. growing in the surrounding areas of Qichun County in China are called Qiai (QA). Qiai is a crop that can be used both as food and in traditional folk medicine. However, detailed qualitative and quantitative analyses of its compounds remain scarce. The process of identifying chemical structures in complex natural products can be streamlined by combining UPLC-Q-TOF/MS data with the UNIFI information management platform and its embedded Traditional Medicine Library. For the first time, 68 compounds in QA were reported by the method in this study. The method of simultaneous quantification of 14 active components in QA using UPLC-TQ-MS/MS was reported for the first time. Following a screening of the activity of QA 70% methanol total extract and its three fractions (petroleum ether, ethyl acetate, and water), it was discovered that the ethyl acetate fraction enriched with flavonoids such as eupatilin and jaceosidin had the strongest anti-inflammatory activity, while the water fraction enriched with chlorogenic acid derivatives such as 3,5-di-O-caffeoylquinic acid had the strongest antioxidant and antibacterial activity. The results provided the theoretical basis for the use of QA in the food and pharmaceutical industries.
