Abstract
The aim of this study was to report the clinical experience of repairing mandibular defects with a deep circumflex iliac artery perforator flap with iliac crest (DCIAPF) and to analyse the relevant anatomical data to guide clinical application. Forty patients with mandibular defects, who underwent reconstruction with a DCIAPF after oncological resection were included in the study. During the operation, anatomical features relevant to the structure of the DCIAPF were measured, including the position of the perforator, mobility of the skin paddle, length of the vascular pedicle, and adipose tissue thickness of the skin paddle. Three types of DCIAPF perforator were identified: type I, with a dominant perforator, which was observed in 17 patients (42.5%); type II, with a dominant perforator that divides into multiple tiny branches, in 20 patients (50%); type III, with no visible dominant perforator, in three patients (7.5%). In summary, the DCIAPF provides adequate bone tissue and satisfactory soft tissue.

Abstract
The repair of mandibular defects is challenging due to the functional and structural complexity of the mandible. The aim of this study was to evaluate the learning curve of mandibular reconstruction using a vascularized iliac crest free flap (ICFF) performed by a single surgeon. This retrospective study used the cumulative sum (CUSUM) method to analyse the operation times of 60 patients who underwent mandibular reconstruction surgery with an ICFF between 2013 and 2022. The results showed that the learning curve could be divided into two phases according to the turning point: phase 1 comprised cases 1-17 and phase 2 comprised cases 18-60. The operation time and length of hospital stay were significantly longer in phase 1 than in phase 2, while there was no significant difference in the flap failure rate or follow-up outcomes between the two phases. In summary, the learning curve of mandibular reconstruction with an ICFF stabilized after approximately 17 cases.

Abstract
Objectives: To examine the proportion and trends of cervical adenocarcinoma in cervical cancer (ICC), mainly including cervical adenocarcinoma (CADC) and squamous cervical cancer (SCC) in China, and to analyze the distribution of human papilloma virus (HPV) in CADC and SCC. Methods: Published studies reporting HPVs distribution in various histological types or relative proportions of CADC in ICC in China were identified manually and searched systematically in Medline, Embase, Cochrane Library databases, CNKI and Wanfang since the databases were established until October 2022. Meta-analysis was performed using Stata 16.0 software. And we applied the random-effects models to estimate the combined effect values due to the high heterogeneity. Results: Twenty-three studies were eligible. The relative prevalence of CADC was 9.0% (95% CI, 7.7%-10.3%). According to the diagnosis time of ICC, the patients were divided into three time periods, which is 1979-2005, 2006-2011, 2012-2022 respectively. The prevalence of CADC by time was: 6.0% in 1979-2005, 8.1% in 2006-2011, and 9.5% in 2012-2022, respectively, with no statistically significant trend in proportions over time (χ2=5.03, P=0.081). Meanwhile, the percentage of CADC also varies by regions, and the highest percentage of CADC was found in the eastern region (11.2%), followed by the western region (7.3%) and the central region (5.9%). The total prevalence of HPV infection in CADC was 72.3%, which was lower than 92.0% in SCC, and the difference was statistically significant (χ2=300.89, P<0.01). To be specific, the top three HPV types prevalent in CADC were HPV18 (45.0%), HPV16 (22.0%), and HPV52 (7.3%), and those prevalent in the SCC were HPV16 (64.2%), HPV52 (5.6%), HPV18 (5.4%). The results of the Egger's test, and Begg's test showed that there was no publication bias in this study and sensitivity analysis showed that the results of this study were fairly stable. Conclusions: The proportion of CADC in China has increased in a limited way in the past decades, and there are regional differences in the proportion of CADC. The predominant type is HPV18 in CADC and HPV16 in SCC. To eliminate the limitations of the secondary literature, a multicenter study with consistent diagnostic levels and identical HPV genotyping tests is still needed in the future to better characterize the relative proportion of cervical adenocarcinoma and the trend of HPV changes, which will provide a basis for the improvement of HPV vaccine and screening policies.

Abstract
Objective: To assess the association between short-term ambient air pollution exposure and arterial stiffness and whether obesity modifies these associations. Methods: A cross-sectional study was conducted based on Fangshan family cohort in Beijing. The 24 hours average air pollutant levels on the day cohort participants took baseline survey were calculated as short-term air pollution. A generalized additive model (GAM) with Gaussian links was used to estimate changes in typical carotid artery intima-media thickness (CIMT), brachial-ankle pulse wave velocity (BAPWV), pulse pressure (PP) and ankle-branchial index (ABI) after short-term exposure to each air pollution (PM2.5, PM10, SO2, NO2, CO). The cross-product terms of each air pollution, body mass index (BMI), and waist-to-hip ratio were included in the GAM model to test the interaction. Further, they conducted a stratified analysis to test their effects on the relationship between short-term exposure to each air pollution and the arterial stiffness indicators. Results: A total of 4 211 individuals were included in the analysis. Individuals' age was (58.9±8.7) years, of which 2 268 (53.9%) were female. Several covariates, including sociodemographic factors, lifestyle behaviors, and history of drugs, were included in the analysis. The results of the GAM analysis showed that an increase in PM2.5 (β=2.912×10-4, 95%CI: 1.424×10-4-4.400×10-4, P<0.001), CO (β=0.027, 95%CI: 0.011-0.043, P<0.001), SO2 (β=2.070×10-3, 95%CI: 7.060×10-4-3.430×10-3, P=0.003), and NO2 (β=3.650×10-4, 95%CI: 2.340×10-5-7.060×10-4, P=0.036) were associated with an increase in CIMT, while an increase in PM10 (β=0.018, 95%CI: 0.002-0.033, P=0.028) was associated with an increase in PP in the study population. Besides, the waist-to-hip ratio had an effect-modification on the correlation of short-term exposure of PM2.5 (interaction P=0.015), NO2 (interaction P=0.008), and CO (interaction P=0.044) with CIMT, and the correlation between short-term exposure of PM2.5 (interaction P=0.002), NO2 (interaction P=0.010), CO (interaction P=0.029), PM10 (interaction P<0.001) with PP. The significant association between CIMT, PP, and air pollution concentrations was more visible in people with lower waist-to-hip ratios. Conclusions: Short-term ambient air pollution exposure was associated with arterial stiffness indicators, and there was an effect modification of waist-to-hip ratio on these associations, and lower waist-to-hip ratios may enhance the association between air pollution exposure and indicators.

Abstract
In order to investigate the clinical manifestations and laboratory findings associated with brucellosis for the purpose of facilitating prompt clinical diagnosis and effective treatment, as well as to offer a laboratory reference for the prevention of brucellosis outbreaks. In this study, a retrospective cohort design was employed to gather epidemiological characteristics, clinical symptoms, and associated laboratory data from 391 patients diagnosed with bacterial culture-positive brucellosis at the People's Hospital of Ningxia Hui Autonomous Region between 2019 and 2023. The patients were categorized into four age groups, with each group representing a 20 years age interval. Statistical analyses were conducted to examine the differences between these age groups using R version 4.3.2 and SPSS version 24.0 software. The results showed that among the 391 cases of brucellosis patients, fever (241 cases, 61.64%), lumbar and leg joint pain (225 cases, 57.54%), abnormal liver function (124 cases, 31.71%), spleen enlargement (78 cases, 19.95%), and cholecystitis (75 cases, 19.18%) were identified as the most prevalent clinical symptoms. Furthermore, the presence of clinical symptoms such as fever, lumbar and leg joint pain, abdominal pain and distension, headache, dizziness, rash, and complications including abnormal liver function, cholecystitis, spleen enlargement, exhibited statistical significance across four distinct age groups (P<0.05). The initial presentation of acute fever and rash was more pronounced in the pediatric cohort. In contrast, the youth group exhibited a higher prevalence of acute fever, liver function abnormalities, dizziness, headache, and splenomegaly. Furthermore, the strong-age group and the older age group more frequently experienced lumbar and leg joint pain, and symptoms related to the liver, gallbladder, spleen, and digestive system. In terms of laboratory examination, the rates of decreased white blood cell count (WBC), red blood cell count (RBC) and platelet count (PLT) were 18.91% (73 cases), 28.94% (112 cases) and 22.34% (86 cases), respectively. C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total biluric acid (TBA), adenosine deaminase (ADA), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), procalcitonin (PCT), and D-Dimer (D-Dimer). The proportion of patients with elevated quantitative test results was 88.56% (271 cases), 50.90% (197 cases), 52.20% (202 cases), 23.82% (91 cases), 75.72% (290 cases), 23.06% (89 cases), 40.89% (157 cases), 68.34% (218 cases) and 73.33% (209 cases), respectively. Among them, the quantitative detection results of CPR, ALP and D-Dimer had statistical significance among the 4 age groups (χ2=16.366,28.089,7.880,P<0.05). Abnormally elevated laboratory parameters, including C-reactive protein (CRP), alkaline phosphatase (ALP), and D-dimer, were more pronounced in middle-aged and older cohorts, with a positive correlation to advancing age. Among the 391 brucella culture positive specimens, the top three departments with the highest number of isolations were infectious disease (52.4%, 204 cases), emergency (9.5%, 37 cases) and orthopedics (8.4%, 33 cases). In conclusion, the clinical manifestations of brucellosis are multifaceted and heterogeneous, frequently involving multiple organ systems, and the laboratory test results exhibit considerable variability. These findings indicate that clinicians should integrate clinical features of brucellosis with laboratory test results, considering the patient's age group, to enhance diagnostic accuracy and triage efficiency in suspected cases. Improving relevant diagnostic examinations can thereby aid in the effective control and prevention of the disease.

Abstract
Statins therapy is efficacious in diminishing the risk of major cardiovascular events in diabetic patients. However, our research has uncovered a correlation between the prolonged administration of statins and an elevated risk of myocardial dysfunction in patients with type II diabetes mellitus (TIIDM). Here, we report the induction of sterol regulatory element-binding protein 1 (SREBP1) activation, associated lipid peroxidation, and the consequent diabetic myocardial dysfunction after statin treatment and explored the underlying mechanisms. In db/db mice, we observed that 40 weeks atorvastatin (5 and 10 mg/kg) and rosuvastatin (20 mg/kg) administration exacerbated diabetic myocardial dysfunction by echocardiography and cardiomyocyte contractility assay, increased myocardial inflammation and fibrosis as shown by CD68, IL-1β, Masson's staining and Collagen1A1 immunohistochemistry (IHC) staining, increased respiratory exchange ratio (RER) by metabolic cage system assessment, exacerbated mitochondrial structural pathological changes by transmission electron microscopy (TEM) examination, increased deposition of lipid and glycogen by TEM, Oil-red and periodic acid-schiff stain (PAS) staining, which were corresponded with augmented levels of myocardial SREBP1 protein and lipid peroxidation marked by 4-hydroxynonenal (4-HNE) staining. Comparable myocardial fibrosis was also observed in KK-ay and low-dose streptozotocin (STZ)-induced TIIDM mice. Elevated SREBP1 levels were observed in the heart tissues from diabetic patients, which was positively correlated with their myocardial dysfunction. To elucidate the role of statin induced SREBP1 in lipid peroxidation and lipid deposition and related mechanism, we cultured neonatal mouse primary cardiomyocytes (NMPCs) and treated them with atorvastatin (10 μM, 24 h), tracing with [U-13C]-glucose and evaluating for SREBP1 expression and localization. We found that statin treatment elevated de novo lipogenesis (DNL) and the levels of SREBP1 cleavage-activating protein (SCAP), reduced the interaction of SCAP with insulin-induced gene 1 (Insig1), and enhance SCAP/SREBP1 translocation to the Golgi, which facilitate SREBP1 cleavage leading to its nuclear trans-localization and activation in NMPCs. Ultimately, SREBP1 knockdown or l-carnitine mitigated long-term statins therapy induced lipid peroxidation and myocardial fibrosis in low-dose STZ treated SREBP1+/- mice and l-carnitine treated db/db mice. In conclusion, we demonstrated that statin therapy may augment DNL by activating SREBP1, resulting in myocardial lipid peroxidation and lipid deposition.

Abstract
Background Breast cancer (BRCA) constitutes one of the principal causes of death among women. The objective of this study was to explore the impact of glucose-aminotransferase 3 (GCNT3) on the growth, invasion, and metastasis of BRCA cells. Additionally, the aim of this research was to clarify the underlying molecular mechanisms through which GCNT3 influences the development and progression of BRCA and to ascertain the potential of GCNT3 as a novel BRCA biomarker. Methods Analysis involved data sourced from the The Cancer Genome Atlas database (TCGA). Expression levels of GCNT3 were measured using Western blot analysis and immunohistochemistry (IHC). Additionally, cell functionality tests were performed posttransfection with GCNT3-specific interference plasmids to assess the influence of GCNT3 in BRCA by using EdU assay, transwell assay, and flow cytometric assay, as well as PI3K/AKT signaling pathway. Results GCNT3 levels were notably elevated in BRCA tissues compared to adjacent noncancerous tissues. Reducing GCNT3 expression significantly diminished the proliferation, invasion, and migration capabilities of BRCA cells (P<0.05) and concurrently increased apoptosis (P<0.05). The data also indicated that GCNT3 may be involved in activating the PI3K/AKT signaling pathway. Conclusions Elevated GCNT3 expression in BRCA tissues suggests the potential of GCNT3 to be a biomarker for predicting BRCA prognosis. The regulation of p-PI3K and p-AKT levels by GCNT3 appears to considerably inhibit BRCA cell development and progression.

Abstract
OBJECTIVE To investigate the function of mitophagy in instructing T-cell differentiation of patients with rheumatoid arthritis (RA). METHOD The mRNA and protein levels of optic atrophy protein-1 were detected in T cells from 94 RA patients and 37 age- and sex-matched healthy individuals by quantitative polymerase chain reaction and Western blotting. The impact of mitophagy on the differentiation of T cells was determined by flow cytometry. The therapeutic effect of targeting mitophagy was explored in humanized RA chimeras. RESULTS Our study showed that T cells exerted high levels of mitophagy in RA patients. Since multiple T-cell subtypes play crucial roles in RA, we determined that mitophagy had a significant impact on the differentiation of tissue-resident memory T (Trm) cells, but not Th1 or Th17 cells. Importantly, we demonstrated that inhibiting mitophagy significantly reduced the number of Trm cells and downregulated inflammatory responses, as evidenced by diminished levels of T cell receptor β, interferon-γ, and interleukin-17A, in the humanized RA chimeras. CONCLUSIONS Mitophagy is elevated in RA T cells, leading to maldifferentiation of Trm cells in RA patients. Since these findings were obtained from clinical patients, mitophagy may be a potential therapeutic target for RA treatment.

Abstract
Epidemiology and medical statistics are essential courses for undergraduate students majoring in clinical medicine. By studying the two courses, they can obtain the core skills for their future clinical practice. High-level medical schools both at home and abroad have accumulated successful experiences in curriculum, teaching methods and teaching models of the two disciplines. These colleges have also carried out the exploration of the curriculum reform centering on "organ systems integration". This paper summarizes the current status of epidemiology and medical statistics teaching and curriculum integration in representative medical schools both at home and abroad, and puts forward suggestions for deepening teaching reform and optimizing the curriculum system to provide reference for the integration of epidemiology and medical statistics curriculums for undergraduate students majoring in clinical medicine in China.

Abstract
Inspired by human sense organs, AI is advancing toward multimodal perception, with display technology evolving into intelligent human-computer interaction tools. However, hardware networks with multimodal responses connected by different devices bring problems such as delayed information transfer and inefficiency. Thus, an innovative three-mode photosensitive synaptic LED (PSSL) is first proposed by adding a photosensitive layer indacenodithiophene-benzothiadiazole (IDTBT) to the quantum-dot light-emitting diode (QLED), switched by changing the bias voltage. The self-powered PSSL has a photoresponse range from 310 nm to 808 nm (ultraviolet-near-infrared, UV-NIR). The device exhibits a bipolar response under red and UV light at 1 V. When the voltage reaches the turn-on voltage, the PSSL device turns into a neuromorphic LED, exhibiting conductivity enhancement under red-light irradiation and suppression under UV-light irradiation. As a result, the PSSLs are expected to be applied in the field of optical encryption communication and in neuromorphic display.

Abstract
Atomic force microscopy (AFM) is a kind of high-precision instrument to measure the surface morphology of various conductive or nonconductive samples. However, obtaining a high-resolution image with standard AFM scanning requires more time. Using block compressive sensing (BCS) is an effective approach to achieve rapid AFM imaging. But, the routine BCS-AFM imaging is difficult to balance the image quality of each local area. It is easy to lead to excessive sampling in some flat areas, resulting in time-consuming. At the same time, there is a lack of sampling in some areas with significant details, resulting in poor imaging quality. Thus, an innovative adaptive BCS-AFM imaging method is proposed. The overlapped block is used to eliminate blocking artifacts. Characteristic parameters (GTV, Lu, and SD) are used to predict the local morphological characteristics of the samples. Back propagation neural network is employed to acquire the appropriate sampling rate of each sub-block. Sampling points are obtained by pre-scanning and adaptive supplementary scanning. Afterward, all sub-block images are reconstructed using the TVAL3 algorithm. Each sample is capable of achieving uniform, excellent image quality. Image visual effects and evaluation indicators (PSNR and SSIM) are employed for the purpose of evaluating and analyzing the imaging effects of samples. Compared with two nonadaptive and two other adaptive imaging schemes, our proposed scheme has the characteristics of a high degree of automation, uniformly high-quality imaging, and rapid imaging speed. HIGHLIGHTS: The proposed adaptive BCS method can address the issues of uneven image quality and slow imaging speed in AFM. The appropriate sampling rate of each sub-block of the sample can be obtained by BP neural network. The introduction of GTV, Lu, and SD can effectively reveal the morphological features of AFM images. Seven samples with different morphology are used to test the performance of the proposed adaptive algorithm. Practical experiments are carried out with two samples to verify the feasibility of the proposed adaptive algorithm.

Abstract
The onset of myasthenia gravis (MG) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) seriously threatens the survival of patients, since it is acute, and is prone to rapid progression. Two patients with acute myeloid leukemia (AML), who had undergone allo-HSCT developed shortness of breath, and gradually developed cervical weakness and dyspnea. The acetylcholine receptor (AChR) antibody and neostigmine test enabled the diagnosis of MG. The condition of the patients improved after treatment with pyridostigmine bromide, glucocorticoids and rituximab.

Recent Pat Anticancer Drug Discov 2024; 19:PRA-EPUB-143572. [PMID: 39360530 DOI: 10.2174/0115748928318948240920044716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 08/20/2024] [Accepted: 08/22/2024] [Indexed: 10/04/2024]
Abstract
OBJECTIVE To investigate the underlying mechanism by which quercetin (Que) regulates macrophage polarization and its subsequent therapeutic effect on liver fibrosis, an important pathological precondition for hepatocellular carcinoma (HCC). METHODS In vitro experiments were performed on the RAW264.7 mouse macrophage line. After the induction of M1-type macrophages with LPS, the effects of Que on cell morphology, M1/M2 surface marker expression, cytokine expression, and JAK2/STAT3 expression were analyzed. In vivo, male SD rats were used as a model of CCL4-induced hepatic fibrosis, and the effects of Que on serum aminotransferase levels, the histopathological structure of liver tissues, and macrophage-associated protein expression in liver tissues were analyzed. RESULTS In vitro experiments revealed that Que can suppress the activation of the JAK2/STAT3 signaling pathway, leading to decreases in the expression of M1 macrophage surface markers and cytokines. Additionally, Que was found to increase the expression of M2 macrophage surface markers and cytokines. In vivo, assays demonstrated that Que significantly ameliorated the development of inflammation and fibrosis in a rat liver fibrosis model. CONCLUSION Que can inhibit hepatic fibrosis by promoting M1 to M2 macrophage polarization, which could be associated with its ability to suppress the JAK2/STAT3 signaling pathway in macrophages.

Abstract
Aims Neratinib has emerged as significant theraputic option for breast cancer treatment. However, despite its approval, numerous adverse drug events (ADEs) associated to it remain unrecognized and unreported. This study aims to mine and analyze the signals of ADEs related to neratinib from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database, providing insights for safe and rational clinical use of drug. Methods All the neratinib-related ADEs data were collected from FAERS database from the third quarter (Q3) of 2017 to the fourth quarter (Q4) of 2023. After standardizing the data, 4 disproportionality methods were used to assess the correlation between neratinib and ADEs. Results Of the 1,544 ADEs implicating neratinib as the primary suspected drug, a combined total of 48 preferred terms (PTs) and 10 system organ classes (SOCs) showed significant disproportionality accross all four algorithms simultaneously. These SOCs included gastrointestinal disorders (n = 2,564, ROR 7.14), general disorders and administration site conditions (n = 958, ROR 0.77) and injury poisoning and procedural complications (n = 474, ROR 0.58) among others. Upon comparison with the neratinib manual, 34 ADEs not documented in the manual were found at the PT level. Conclusion Our study provide new real-world evidence for drug safety information of neratinib. While the majority of our findings were aligned with the information provided in the manual. We identified additional ADEs not previously documented. Consequently, further studies are needed to validate unreported ADEs to ensure the efficacy and safety of neratinib for patients.

Abstract
We propose and demonstrate a radio-frequency (rf) atomic magnetometer based on parametric resonances. Previously, most rf atomic magnetometers are based on magnetic resonances and their sensitivities are often limited by spin-exchange relaxation. Here, we introduce a novel scheme for an rf magnetometer where the rf magnetic field is measured by exciting the parametric resonances instead of magnetic resonances using parametric modulation fields. In this way, the spin-exchange relaxation is almost eliminated. Benefiting from the low spin relaxation rate, the parametric resonance scheme exhibits a narrower linewidth and stronger signal, which results in a higher sensitivity. With a 6×6×3 mm^{3} Rb atomic vapor cell, we developed an rf atomic magnetometer with a noise floor of 2 fT/Hz^{1/2}, which is about one order of magnitude higher than the sensitivity achieved in the magnetic-resonance-based scheme. The presented rf detection scheme holds promise in advancing rf atomic magnetometers and brings new insight into their various applications.

Abstract
Prior evidence suggests that altered energy metabolism plays a crucial role in the development of fibrotic diseases. Recent research indicates that systemic sclerosis (SSc) patients have potentially benefited from energy management, implying that basal metabolic rate (BMR), a vital energy metabolic parameter, may be related to SSc. However, the causal effect of BMR on SSc remains unknown. Thus, we aimed to elucidate the causal links between BMR and SSc. Based on summary statistics from the genome-wide association studies (GWAS) database, two-sample Mendelian randomization (MR) was applied to explore causality between BMR and SSc. The causal relationships were assessed employing inverse variance weighted (IVW), MR-Egger, and weighted median (WM) methods. Meanwhile, several sensitivity analyses were carried out to ensure the robustness of the findings. There was an underlying genetic association of BMR on SSc (OR = 0.505, 95% CI: 0.272-0.936, P = 0.030). Moreover, no significant causal effect between SSc and BMR was observed in the reverse MR analysis (OR = 0.999, 95% CI: 0.997-1.001, P = 0.292). According to the sensitivity analysis, the presence of heterogeneity and genetic pleiotropy was not detected. Our findings, derived from a genetic perspective, provide robust evidence of a causal connection between BMR and SSc. To verify these results and clarify the potential mechanisms, further research is warranted.

Abstract
Background Aprepitant, fosaprepitant, and netupitant are three common neurokinin-1 receptor antagonists (NK-1RAs) used to prevent chemotherapy-induced nausea and vomiting, following highly or moderately emetogenic chemotherapy. Understanding their different adverse event (AE) profiles may help clinicians make appropriate treatment decisions. Methods All data collected from the FDA Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the fourth quarter of 2023 underwent disproportionality analysis to detect, evaluate, and compare AE signals of the three NK-1RAs. Results A total of 3,904, 1,123, and 243 AE reports related to aprepitant, fosaprepitant, and netupitant, respectively, were extracted from the FAERS database. Of these, more than 50% of respondents were female, and most of them were aged 45-65 years. General disorders and administration-site conditions, and gastrointestinal disorders were the most frequent signals in the system organ class of the three NK-1RA drugs. In addition, aprepitant was strongly associated with joint deposit (ROR = 26.27) and fosaprepitant was closely related to seizure-like phenomena (ROR = 26.90); two preferred terms (PTs) were not mentioned in the manual. Statistically, netupitant was likely to induce death (N = 63, ROR = 8.78, 95% CI: 6.75-11.42). Additionally, neutropenic colitis, colitis, and stomatitis were unique to netupitant. Furthermore, the AE profiles of the three NK-1RA drugs were different by gender. Conclusion The AE profiles for aprepitant, fosaprepitant, and netupitant were different. In addition to paying attention to common AEs, clinicians need to pay attention to new emerging AEs, such as joint deposit, seizure-like phenomena, neutropenic colitis, colitis, and stomatitis, regarding the three NK-1RA drugs. Furthermore, the AE compositions of the three NK-1RA drugs were different in different genders, and clinicians should take these factors into account when selecting NK-1RAs for CINV treatment.

Abstract
Advancing biomagnetic measurement capabilities requires a nuanced understanding of sensor performance beyond traditional metrics. This study introduces Biomagnetism Evaluation via Simulated Testing (BEST), a novel methodology combining a current dipole model simulating cardiac biomagnetic fields with a convolutional neural network. Our investigation reveals that optimal sensor array performance is achieved when sensors are in close proximity to the magnetic source, with a shorter effective domain. Contrary to common assumptions, the bottom edge length of the sensor has a negligible impact on array performance. BEST provides a versatile framework for exploring the influence of diverse technical indicators on biomagnetic sensor performance, offering valuable insights for sensor development and selection.

Abstract
Recent research has identified that miR-539-3p impedes chondrogenic differentiation, yet its specific role and underlying mechanisms in childhood-onset osteoarthritis (OA) remain unclear. This study found that miR-539-3p levels were considerably lower in cartilage samples derived from childhood-onset OA patients compared to the control group. Enhancing miR-539-3p expression or suppressing RUNX2 expression notably reduced apoptosis, inflammation, and extracellular matrix (ECM) degradation in OA chondrocytes. In contrast, reducing miR-539-3p or increasing RUNX2 had the opposite effects. RUNX2 was confirmed as a direct target of miR-539-3p. Further experiments demonstrated that miR-539-3p targeting RUNX2 effectively lessened apoptosis, inflammation, and ECM degradation in OA chondrocytes, accompanied by changes in key molecular markers like reduced caspase-3 and matrix etallopeptidase 13 (MMP-13) levels, and increased B-cell lymphoma 2 (Bcl-2) and collagen type X alpha 1 chain (COL2A1). This study underscores the pivotal role of miR-539-3p in alleviating inflammation and ECM degradation in childhood-onset OA through targeting RUNX2, offering new insights for potential therapeutic strategies against this disease.

Abstract
Objective: To explore the menopause status of patients with rheumatoid arthritis (RA) and clinical characteristics of perimenopausal RA patients. Methods: A cross-sectional study. Female RA patients were recruited retrospectively in the Sun Yat-Sen Memorial Hospital from August 2015 to August 2023. Clinical data were collected, including onset age, disease duration, RA disease activity indicators, functional assessment, and radiographic scores. According to menopausal status, the patients were categorized as pre-menopausal, perimenopausal and post-menopausal groups to explore their menopausal and clinical characteristics. Results: A total of 1 151 female patients were enrolled, with a mean age of (50.2±13.0) years. At enrollment, there were 470 (40.8%), 140 (12.2%) and 541 (47.0%) patients in pre-menopause, perimenopause and post-menopause status, respectively. The mean age of menopause was (49.0±4.2) years. Compared with pre-menopausal group, perimenopausal RA patients had higher disease activity indicators [clinical disease activity index (CDAI) 17 (6, 26) vs 10 (3, 19) ], higher levels of inflammation [erythrocyte sedimentation rate (ESR) 35 (21, 65) vs 26 (14, 44) mm/1h, C-reactive protein (CRP) 6.2 (3.2, 16.8) vs 3.3 (3.2, 13.6) mg/L], and a higher proportion of functional limitation [25.0%(35/140) vs 10.4%(49/470)] (all P<0.016 7); while there was no significant differences in disease activity[M(Q1, Q3)] [CDAI 17 (6, 26) vs 14 (6, 25)], levels of inflammation [ESR 35(21, 65) vs 42 (23, 72) mm/1h, CRP 6.2 (3.2, 16.8) vs 6.2 (3.3, 23.9) mg/L] and functional limitation [25.0%(35/140) vs 28.8%(156/541)] when compared with those in post-menopausal group (all P>0.016 7). In RA patients during the perimenopausal period, 49 cases (35.0%) developed RA during this period. Compared with patients with RA onset during reproductive age, patients with RA onset during the perimenopausal period had higher numbers of 28-joint tender joints [7 (2, 10) vs 4 (0, 8)], higher CDAI [20 (12, 29) vs 14 (4, 24)], and higher ESR [45 (25, 72) vs 32 (18, 56) mm/1h] (all P<0.05). Conclusion: Perimenopausal patients with RA have severe disease activity and functional limitation.
