Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

INTRODUCTION: Endometriosis (EMS) is a common gynaecological disorder linked to metabolic disturbances. However, evidence on the associations between lipid accumulation product (LAP) and visceral adiposity index (VAI) with the risk of EMS remains limited. This study aimed to explore the potential associations between LAP, VAI and EMS. METHOD: Data were obtained from the 1999-2006 National Health and Nutrition Examination Survey (NHANES), including a total of 2046 samples. Weighted multivariable logistic regression models and smoothed curve fitting were used to assess the associations between LAP, VAI and EMS. Additionally, subgroup analyses and interaction tests were conducted to evaluate intergroup differences in the associations between LAP, VAI and EMS. RESULTS: In the fully adjusted model, higher Log2 LAP (odds ratio [OR] 1.256, 95% confidence interval [CI] 1.102-1.431, P=0.0014) and Log2 VAI (OR 1.287, 95% CI 1.105-1.498, P=0.0022) were significantly associated with increased EMS risk. Participants in the highest quartile of Log2 LAP (OR 1.983, P=0.0029) and Log2 VAI (OR 1.690, P=0.0486) had a higher risk of EMS. Subgroup analysis showed stronger associations among women with diabetes (Log2 LAP OR 3.681, P=0.009; Log2 VAI OR 4.849, P=0.041). CONCLUSION Elevated LAP and VAI were independently associated with an increased risk of EMS. LAP and VAI may serve as potential indicators for assessing EMS-related risk, suggesting that visceral obesity and lipid metabolic disturbances might play roles in the pathophysiological process of EMS. These findings underscore the potential of LAP and VAI as non-invasive markers for EMS risk, warranting further validation in clinical settings.

OBJECTIVE: To study the clinical effects of ibrutinib in the treatment of relapsed/refractory diffuse large B-cell lymphoma (RRDLBCL). METHODS: A total of 101 patients with RRDLBCL in Daqing People's Hospital from September 2019 to September 2022 were selected. 45 patients were received ibrutinib monotherapy, 36 patients were received a combination therapy of ibrutinib, rituximab, and lenalidomide, and 20 patients were received a combination therapy of ibrutinib and lenalidomide. The clinical effects were observed. RESULTS: The median duration of treatment for all patients was 4 (2-9) months. The disease control rates(DCR) and objective response rates(ORR) in the ibrutinib monotherapy group were 46.67% and 26.67%, respectively. In the combination therapy group of ibrutinib, rituximab, and lenalidomide, the DCR and ORR were 69.44% and 44.44%, respectively. In the combination therapy group of ibrutinib and lenalidomide, the DCR and ORR were 60.00% and 35.00%, respectively. The DCR and ORR in the combination therapy group of ibrutinib, rituximab, and lenalidomide were significantly higher than those in the ibrutinib monotherapy group (P < 0.05). There were no significant differences in DCR and ORR between the combination therapy group of ibrutinib and lenalidomide and the ibrutinib monotherapy group (P >0.05). The median follow-up time of all patients was 15 (5-35) months, with a median overall survival(OS) of 21.0 (15.8-26.2) months and a median progression-free survival(PFS) of 14.0 (12.1-15.9) months. In the ibrutinib monotherapy group, the median OS and PFS were 15.0 (12.1-17.9) months and 12.0 (11.0-13.0) months, respectively. In the combination therapy group of ibrutinib and lenalidomide, the median OS and PFS were 22.0 (13.3-30.7) months and 16.0 (14.1-19.7) months, respectively. In the combination therapy group of ibrutinib, rituximab, and lenalidomide, the median OS and PFS were 23.0 (19.7-26.3) months and 17.0 (14.8-19.1) months, respectively. The median OS and PFS in the combination therapy group of ibrutinib, rituximab, and lenalidomide were significantly higher than those in the ibrutinib monotherapy group (P < 0.05). There were no significant differences in median OS and PFS between the combination therapy group of ibrutinib and lenalidomide and the combination therapy group of ibrutinib, rituximab, and lenalidomide (P >0.05). Hematological adverse reactions included neutropenia in 14 cases (13.86%), thrombocytopenia in 16 cases (15.84%), and leukopenia in 13 cases (12.87%). Non-hematological adverse reactions mainly included nausea and vomiting in 33 cases (32.67%) and fatigue in 44 cases (43.56%). CONCLUSION Ibrutinib has certain clinical effects and good safety in the treatment of RRDLBCL.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)‍-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.

Objective To explore the value of metagenomic next-generation sequencing(mNGS)technology in the etiological diagnosis of sepsis in preterm infants following antibiotic use.Methods A retrospective analysis of medical records for 45 preterm infants with sepsis who were treated at Henan Provincial People's Hospital.All patients received antibiotic treatment for ≥3 days and underwent both blood culture and mNGS testing.The detection rates of pathogens by blood culture and mNGS testing were compared.Results The positive detection rate of pathogens by blood mNGS was higher than that by blood culture(44％vs 4％;P＜0.001).Blood mNGS detected 28 strains of pathogens,including 23 bacteria,4 fungi,and 1 Ureaplasma parvum.Blood culture identified one case each of Rhodotorula mucilaginosa and Klebsiella pneumoniae.In the group treated with antibiotics for＞10 days,the positive rate of blood mNGS testing was higher than that of blood culture(40％vs 3％;P＜0.001);similarly,in the group treated with antibiotics for ≤10 days,the positive rate of blood mNGS testing was also higher than that of blood culture(53％vs 7％;P=0.020).Treatment plans were adjusted based on blood mNGS results for 13 patients,with an effectiveness rate of 85％(11/13).Conclusions In preterm infants with sepsis following antibiotic use,the positive rate of pathogen detection by blood mNGS is higher than that by blood culture and is unaffected by the duration of antibiotic use.Therefore,mNGS testing can be considered for confirming pathogens when clinical suspicion of infection is high but blood culture fails to detect the pathogen.

The development, progression, and curative efficacy of head and neck squamous cell carcinoma (HNSCC) are influenced by complex interactions between epithelial and immune cells. Nevertheless, the specific changes in the nature of these interactions and their underlying molecular mechanisms in HNSCC are not yet fully understood. Cuproptosis, a form of programmed cell death that is dependent on copper, has been implicated in cancer pathogenesis. However, the understanding of cuproptosis in the context of HNSCC remains limited. In this study, we have discovered that cuproptosis-related long non-coding RNAs (CRLs) known as JPX play a role in promoting the expression of the oncogene urokinase-type plasminogen activator (PLAU) by competitively binding to miR-193b-3p in HNSCC. The increased activity of the JPX/miR-193b-3p/PLAU axis in malignant epithelial cells leads to enhanced cell proliferation, migration, and invasion in HNSCC. Moreover, the overexpression of PLAU in tumor epithelial cells facilitates its interaction with the receptor PLAUR, predominantly expressed on macrophages, thereby influencing the abnormal epithelial-immune interactome in HNSCC. Notably, the JPX inhibitor Axitinib and the PLAU inhibitor Palbociclib may not only exert their effects on the JPX/miR-193b-3p/PLAU axis that impacts the malignant tumor behaviors and the epithelial-immune cell interactions but also exhibit synergistic effects in terms of suppressing tumor cell growth and arresting cell cycle by targeting epidermal growth factor receptor (EGFR) and cyclin-dependent kinase (CDK4/6) for the treatment of HNSCC.

AIM: To evaluate the changes of retinal microvascular density in patients with sellar region tumor, and its correlation with the damage to visual field, and to explore its application value in evaluating optic nerve injury of those patients.METHODS: Cross-sectional study. A total of 157 patients(292 eyes)with sellar region tumor, including 82 cases(152 eyes)of pituitary adenoma and 75 cases(140 eyes)of craniopharyngioma, were selected from neurosurgery department and ophthalmology department of Beijing Tiantan Hospital, Capital Medical University between October 2018 and May 2022. A total of 90 people(180 eyes)during the same period, including the family members of patients, students and staff in Beijing Tiantan Hospital, Capital Medical University were collected as control group. All participants underwent optical coherence tomography angiography(OCTA)examination. The changes of retinal microvascular density and its correlation with visual field parameters were compared between the two groups.RESULTS: In patients with sellar region tumor, the radial peripapillary capillary(RPC)and superficial retinal capillary plexus(SRCP)density were significantly lower than that in the control group [50.81%(46.49%, 53.49%)vs. 52.78%(50.73%, 54.51%)and 50.57%(48.13%, 52.73%)vs. 51.63%(49.78%, 53.02%), all P<0.05]. The RPC density in the craniopharyngioma group was lower than that in the pituitary adenoma group [49.71%(44.33%, 53.14%)vs. 51.37%(47.42%, 53.95%), P<0.05]. The MD, PSD and VFI of the sellar region tumor group were -4.33(-12.22, -1.85)dB, 3.37(1.91, 8.82)dB and 92%(65%, 97%)respectively. RPC density of patients with sellar region tumor was positively correlated with MD and VFI, and was negatively correlated with PSD. The SRCP density of each quadrant was positively correlated with MD, and was positively correlated with VFI except Para-T and it was negatively correlated with PSD(all P<0.05).CONCLUSION: Retinal microvascular changes were present in patients with sellar region tumor. Lower vessel density indicates more severe damage to visual field. In the clinic, visual field examinations combined with OCTA were helpful to find the optic nerve injury of patients.

Objective:To evaluate the efficacy of ultrasound-guided superior laryngeal nerve block(SLNB) combined with intravenous anesthesia for improving pediatric fiberoptic bronchoscopy.Methods:Forty pediatric patients of either sex, aged 3-6 yr, of American Society of Anesthesiologists Physical Status classificationⅠor Ⅱ, with body mass index of 18-24 kg/m 2, undergoing fiberoptic bronchoscopy in Cangzhou Central Hospital in 2022, were divided into 2 groups ( n=20 each) by a random number table method: ultrasound-guided SLNB plus intravenous anesthesia group (group A) and topical anesthesia plus intravenous anesthesia group (group B). After sedation with dexmedetomidine and esketamine, ultrasound-guided bilateral SLNB was performed with 1% lidocaine 0.5 ml (for each side)in group A, and topical anesthesia was performed with 1% lidocaine in nasal and pharyngeal cavities in group B. After completion of the surgery procedure, propofol was continuously infused at 5 mg·kg -1·h -1 until completion of diagnosis and treatment. An increment of propofol 1 mg/kg was intravenously given if severe bucking or body movement occurred during operation. Mean arterial pressure (MAP), heart rate (HR) and SpO 2 were recorded on admission to the operating room (T 0), immediately after sedation (T 1), immediately after bronchoscopy entering the glottis (T 2), 5 min after start of treatment (T 3) and at the end of examination (T 4). The occurrence of intraoperative hypoxemia, HR <60 bpm, and MAP <50 mmHg were recorded, and the additional dose of propofol was recorded. The venous blood samples were collected at T 0 and T 4 to determine plasma cortisol concentrations by chemiluminescence.The surgeon′s satisfaction score was recorded. The complications of SLNB were also recorded within 2 h after operation in group A. Results:Compared with group B, HR was significantly decreased at T 2 and T 3, SpO 2 was increased, the intraoperative additional dosage of propofol and incidence of hypoxemia were decreased, and the surgeon′s satisfaction score was increased, and the concentrations of cortisol were decreased at T 4 in group A ( P<0.05). No HR<60 bpm and MAP<50 mmHg were found in two groups. No SLNB-related complications were observed after operation in group A. Conclusions:Ultrasound-guided SLNB combined with intravenous anesthesia is safer for pediatric fiberoptic bronchoscopy and can improve the analgesic effect and is more helpful in inhibiting intraoperative stress responses when compared with conventional anesthesia.
