Objective To discuss the application of the"rotating guidewire and correcting the filter recovery hook direction technique"("rotation-correction loop technique"for short),a technique invented by the authors in clinical practice,in the retrieval of complex inferior vena cava filter(IVCF),and to discuss its technical skills and advantages.Methods The clinical data of 417 patients carrying an IVCF,who were admitted to the Department of Vascular Surgery of Second Hospital of Shanxi Medical University of China to retrieve IVCF between January 2022 and December 2022,were retrospectively analyzed.Taking the time spent on the retrieval of IVCF and the intraoperative radiation dose as the evaluation indicators,the advantages and disadvantages of the standard filter retrieval technique,the"rotation-correction loop technique"and the other loop-assisted techniques were compared.Results Both the intraoperative radiation dose and the time spent on the retrieval of IVCF using"rotation-correction loop technique"were remarkably lower than those of other loop-assisted techniques(P＜0.000 1).Conclusion For the retrieval of complex IVCF,especially for the IVCF which is heavily tilted and/or its recovered hook is attached to the vascular wall,the use of"rotation-correction loop technique"can shorten the time spent on the the retrieval of IVCF and reduce the intraoperative radiation dose.This technique carries high safety and practicability,the device is simple and it can be manipulated by single physician,which is conducive to clinical application and promotion.(J Intervent Radiol,2024,33:289-294)

Objective To explore the effect and mechanism of hydroxysafflor yellow A(HSYA)on autophagy in bEnd.3 cells after oxygen-glucose deprivation(OGD).Methods The bEnd.3 cells were divided into normal group(conventional culture),model group(OGD model),HSYA group(OGD model+75 μmol·L-1 HSYA),3-methyladenine(3MA)group(5 mmol·L-1 3MA+OGD model)and 3 MA+HSYA group(5 mmol·L-1 3 MA+OGD model+75 μmol·L-1 HSYA).The level of apoptosis was determined by TUNEL fluorescence staining;Western blot was used to detect the expression of autophagy,blood brain barrier(BBB)related proteins;real time fluorescence quantitative polymerase chain reaction method for determining the expression of sirtuin-1(SIRT1)and forkhead box protein O3a(FOXO3A)mRNA.Results In the normal group,model group,HSYA group,3MA group and 3MA+HSYA group,the positive cells selected for TUNEL staining were 5.00±1.00,28.00±2.00,21.00±3.00,35.33±2.51 and 29.67±2.52;the expression levels of microtubule-associated protein 1 light chain 3-Ⅱ/-Ⅰ(LC3-Ⅱ/-Ⅰ)were 0.90±0.20,1.34±0.10,1.95±0.14,0.76±0.15 and 1.14±0.09;sequestosome 1(P62)were 0.99±0.02,0.60±0.02,0.38±0.01,0.67±0.04 and 0.54±0.01;occludin were 1.39±0.17,0.62±0.15,1.00±0.09,0.40±0.13 and 0.80±0.15;zonula occludens-1(ZO-1)were 1.63±0.20,0.64±0.06,0.98±0.14,0.37±0.14 and 0.87±0.04;SIRT1 mRNA were 1.00±0.00,0.75±0.07,1.69±0.09,0.31±0.02 and 0.56±0.01;FOXO3A mRNA were 1.00±0.00,0.80±0.05,1.47±0.09,0.40±0.01 and 0.62±0.09,respectively.Significant differences were found between model group and normal group,HSYA group and model group,3MA+HSYA group and 3MA group(P＜0.05,P＜0.01,P＜0.001).Conclusion HSYA may enhance autophagy levels in bEnd.3 cells after OGD through the SIRT1/FOXO3A pathway,inhibit cell apoptosis and alleviate BBB damage.

Background::Findings on the association of genetic factors and colorectal cancer (CRC) survival are limited and inconsistent, and revealing the mechanism underlying their prognostic roles is of great importance. This study aimed to explore the relationship between functional genetic variations and the prognosis of CRC and further reveal the possible mechanism.Methods::We first systematically performed expression quantitative trait locus (eQTL) analysis using The Cancer Genome Atlas (TCGA) dataset. Then, the Kaplan-Meier analysis was used to filter out the survival-related eQTL target genes of CRC patients in two public datasets (TCGA and GSE39582 dataset from the Gene Expression Omnibus database). The seven most potentially functional eQTL single nucleotide polymorphisms (SNPs) associated with six survival-related eQTL target genes were genotyped in 907 Chinese CRC patients with clinical prognosis data. The regulatory mechanism of the survival-related SNP was further confirmed by functional experiments.Results::The rs71630754 regulating the expression of endoplasmic reticulum aminopeptidase 1 ( ERAP1) was significantly associated with the prognosis of CRC (additive model, hazard ratio [HR]: 1.43, 95% confidence interval [CI]: 1.08-1.88, P = 0.012). The results of dual-luciferase reporter assay and electrophoretic mobility shift assay showed that the A allele of the rs71630754 could increase the binding of transcription factor 3 (TCF3) and subsequently reduce the expression of ERAP1. The results of bioinformatic analysis showed that lower expression of ERAP1 could affect the tumor immune microenvironment and was significantly associated with severe survival outcomes. Conclusion::The rs71630754 could influence the prognosis of CRC patients by regulating the expression of the immune-related gene ERAP1.

ObjectiveSpatial working memory (SWM) is an important function in cognitive behavior, and working memory impairment can seriously affect the patient’s life and cause great stress to the patient. Intermittent theta burst stimulation (iTBS) has been shown to regulate working memory function by entrainment of neural oscillations in different frequencies of the brain, but its regulation of working memory-related neural oscillations and their synchronization is not clear. The purpose of this study was to study the effect of iTBS on neural oscillation and synchronization in local and transbrain regions of rats, and to explore the mechanism of iTBS in regulating working memory. MethodsTwenty-four rats were randomly divided into four groups according to their age and whether they received iTBS stimulation (AS: adult stimulation group, AC: adult control group, ES: elderly stimulation group, EC: elderly control group). Using the methods of time-frequency distribution, phase synchronization and phase-amplitude coupling analysis, the changes of local field potential signal neural oscillations in the prefrontal and hippocampal brain regions of theta and gamma bands in the process of spatial working memory behavioral tasks in each group of rats were compared and analyzed, and the relationship between the changes of neural oscillations in the two brain regions and the changes in spatial working memory ability of rats was judged based on the Pearson correlation coefficient. ResultsWith the increase of age, the time taken by the elderly rats to learn the spatial working memory task rules increased significantly (P=0.005 6), and the time taken by iTBS stimulation to learn the SWM task rules in adult rats (P=0.001 1) and elderly rats(P=0.009 0) was shortened. At the same time, compared with adult rats, the time-frequency energy of theta and gamma band neural oscillations in the prefrontal and hippocampal brain regions of elderly rats (theta: P<0.000 1; gamma: P<0.000 1) and phase-amplitude coupling across brain regions (PFC-HPC: P=0.000 2; HPC-PFC:P=0.027 7) decreased to a certain extent, and iTBS stimulation could increase the time-frequency energy of neural oscillations of adult rats (theta: P<0.000 1; gamma: P<0.000 1) and elderly rats (theta: P=0.014 4; gamma:P=0.000 6) and the phase-amplitude coupling effect across brain regions in elderly rats (PFC-HPC: P=0.018 0; HPC-PFC: P=0.022 1). In addition, the time-frequency energy and phase-amplitude coupling of signals in each frequency band of the two brain regions were positively correlated with the behavioral accuracy of rats, while the phase synchronization of theta band and gamma band neural oscillations in the two brain regions during working memory was not correlated with the behavioral accuracy. ConclusioniTBS can enhance SWM ability and cognitive function in elderly rats, and this improvement is associated with increased coupling of time-frequency energy and cross-brain phase amplitude of neural oscillations across theta and gamma bands during SWM tasks. Similarly, in adult rats, iTBS enhances SWM ability and cognitive function by increasing the time-frequency energy of theta and gamma band neural oscillations in both brain regions during SWM tasks. Furthermore, in addition to the main findings, this study provides evidence supporting the state-dependent effects of iTBS stimulation to some extent.

Retinal vein occlusion (RVO) is one of the most important retinal vascular diseases in China that leads to severe loss of vision. In recent years, the emergence of various emerging imaging technologies and new drugs has not only deepened our understanding of the natural course of this disease, but also significantly changed the traditional treatment mode of retinal laser photocoagulation as the gold standard, thereby significantly improved the visual prognosis. However, currently in various regions and levels of hospitals in China, the diagnosis and treatment of RVO still rely mainly on their own experience. The awareness and knowledge of RVO among ophthalmologists in various regions still need to be improved. A standardized clinical diagnosis and treatment pathway is needed in order to meet the needs of most RVO patients. Led by the Fundus Disease Group of the Ophthalmology Branch of the Chinese Medical Association and the Fundus Disease Professional Committee of the Ophthalmology Branch of the Chinese Medical Association, based on the existing evidence-based evidence at home and abroad, and following the principles of consensus formulation, Expert consensus on clinical diagnosis and treatment path of retinal vein occlusion in China has been compiled. The consensus systematically and comprehensively elaborated a standardized diagnosis and treatment pathway for RVO. Interpreting the key points in this consensus is helpful to highlight the core ideas, and improve the utilization of this consensus by ophthalmologists from all levels of hospitals.

Objective To investigate the induction factors of hypotension during cesarean section for perilous placenta previa under combined spinal-epidural anesthesia (CSEA) and to construct a nomogram prediction model. Methods A total of 130 parturients who underwent cesarean section for perilous placenta previa under CSEA from January 2020 to December 2023 in Yulin Maternity and Child Healthcare Hospital were selected as study subjects. A self-designed general information questionnaire was used to investigate the basic information and the occurrence of hypotension of the subjects. According to the occurrence of intraoperative hypotension, the patients were divided into hypotension group (47 cases) and non-hypotension group (83 cases). Univariate analysis was performed on the general information of the two groups, and multivariate Logistic regression analysis was used to explore the induction factors of intraoperative hypotension. Results Univariate analysis showed that there were statistically significant differences in body mass index, anesthesia level, presence of multiple pregnancy, preoperative systolic blood pressure, operative time, and the occurrence of Bezold-Jarisch reflex between the two groups (P < 0.05). Multivariate Logistic regression analysis revealed that body mass index≥ 24 kg/m², anesthesia level was in the eighth thoracic vertebra(T8) or above, multiple pregnancy, preoperative systolic blood pressure < 90 mmHg, operative time >1.5 h, and the occurrence of Bezold-Jarisch reflex were independent risk factors for hypotension during cesarean section for perilous placenta previa under CSEA (P < 0.05). A regression equation for the induction factors of hypotension during cesarean section for perilous placenta previa under CSEA was constructed: Logit(P)=-23.211+1.079×(body mass index ≥ 24 kg/m²)+1.101×anesthesia level (≥T8)+3.193×multiple pregnancy+2.214×preoperative systolic blood pressure (< 90 mmHg)+4.606×operative time (>1.5 h)+2.011×occurrence of Bezold-Jarisch reflex. The nomogram showed high discrimination and accuracy for patients with preoperative systolic blood pressure < 90 mmHg. After 1, 000 times of Bootstrap resampling for the nomogram model, a calibration curve was obtained, and the consistency index was calculated as 0.850, indicating good calibration of the nomogram model. The receiver operating characteristic (ROC) curve was plotted, with an area under the curve of 0.896 and 95% confidence interval of 0.802 to 0.956, suggesting good predictive performance. Conclusion Body mass index ≥24 kg/m², anesthesia level ≥ T8, multiple pregnancy, preoperative systolic blood pressure < 90 mmHg, operative time >1.5 h, and the occurrence of Bezold-Jarisch reflex are induction factors for hypotension during cesarean section for perilous placenta previa under CSEA.

Objective: To investigate the differences in clinical characteristics, diagnosis, and treatment of pediatric septic shock in pediatric intensive care unit (PICU) among hospitals of different levels. Methods: This retrospective study enrolled 368 children with septic shock treated in the PICU of Beijing Children's Hospital, Henan Children's Hospital, and Baoding Children's Hospital from January 2018 to December 2021. Their clinical data were collected, including the general information, location of onset (community or hospital-acquired), severity, pathogen positivity, consistence of guideline (the rate of standard attainment at 6 h after resuscitation and the rate of anti-infective drug administration within 1 h after diagnosis), treatment, and in-hospital mortality. The 3 hospitals were national, provincial, and municipal, respectively. Furthermore, the patients were divided into the tumor group and the non-tumor group, and into the in-hospital referral group and the outpatient or emergency admission group. Chi-square test and Mann-Whitney U test were used to analyze the data. Results: The 368 patients aged 32 (11, 98) months, of whom 223 were males and 145 females. There were 215, 107, and 46 patients with septic shock, with males of 141, 51, and 31 cases, from the national, provincial, and municipal hospitals, respectively. The difference in pediatric risk of mortality Ⅲ (PRISM Ⅲ) scores among the national,provincial and municipal group was statistically significant (26(19, 32) vs.19(12, 26) vs. 12(6, 19), Z=60.25,P<0.001). The difference in community acquired septic shock among the national,provincial and municipal group was statistically significant (31.6%(68/215) vs. 84.1%(90/107) vs. 91.3%(42/46), χ²=108.26,P<0.001). There were no significant differences in compliance with guidelines among the 3 groups (P>0.05). The main bacteria detected in the national group were Klebsiella pneumoniae (15.4% (12/78)) and Staphylococcus aureus (15.4% (12/78)); in the provincial group were Staphylococcus aureus (19.0% (12/63)) and Pseudomonas aeruginosa (12.7% (8/63)), and in the municipal group were Streptococcus pneumoniae (40.0% (10/25)) and Enteric bacilli (16.0% (4/25)). The difference in the proportion of virus and the proportion of 3 or more initial antimicrobials used among the national,provincial and municipal group was statistically significant (27.7% (43/155) vs. 14.9% (13/87) vs. 9.1% (3/33), 22.8%(49/215) vs. 11.2%(12/107) vs. 6.5%(3/46), χ²=8.82, 10.99, both P<0.05). There was no difference in the in-hospital mortality among the 3 groups (P>0.05). Regarding the subgroups of tumor and non-tumor, the national group had higher PRISM Ⅲ (31(24, 38) vs. 22 (21, 28) vs.16 (9, 22), 24 (18, 30) vs. 17(8, 24) vs. 10 (5, 16), Z=30.34, 10.45, both P<0.001), and it was the same for the subgroups of in-hospital referral and out-patient or emergency admission (29 (21, 39) vs. 23 (17, 30) vs. 15 (10, 29), 23 (17, 29) vs. 18 (10, 24) vs. 11 (5, 16), Z=20.33, 14.25, both P<0.001) as compared to the provincial and municipal group. There was no significant difference in the in-hospital mortality among the 2 pairs of subgroups (all P>0.05). Conclusion: There are differences in the severity, location of onset, pathogen composition, and initial antibiotics of pediatric septic shock in children's hospitals of different levels, but no differences in compliance with guidelines and in-hospital survival rate.

OBJECTIVE: This study investigated the effects of bis (2-butoxyethyl) phthalate (BBOP) on the onset of male puberty by affecting Leydig cell development in rats. METHODS: Thirty 35-day-old male Sprague-Dawley rats were randomly allocated to five groups mg/kg bw per day that were gavaged for 21 days with BBOP at 0, 10, 100, 250, or 500 mg/kg bw per day. The hormone profiles; Leydig cell morphological metrics; mRNA and protein levels; oxidative stress; and AKT, mTOR, ERK1/2, and GSK3β pathways were assessed. RESULTS: BBOP at 250 and/or 500 mg/kg bw per day decreased serum testosterone, luteinizing hormone, and follicle-stimulating hormone levels mg/kg bw per day (P < 0.05). BBOP at 500 mg/kg bw per day decreased Leydig cell number mg/kg bw per day and downregulated Cyp11a1, Insl3, Hsd11b1, and Dhh in the testes, and Lhb and Fshb mRNAs in the pituitary gland (P < 0.05). The malondialdehyde content in the testis significantly increased, while Sod1 and Sod2 mRNAs were markedly down-regulated, by BBOP treatment at 250-500 mg/kg bw per day (P < 0.05). Furthermore, BBOP at 500 mg/kg bw per day decreased AKT1/AKT2, mTOR, and ERK1/2 phosphorylation, and GSK3β and SIRT1 levels mg/kg bw per day (P < 0.05). Finally, BBOP at 100 or 500 μmol/L induced ROS and apoptosis in Leydig cells after 24 h of treatment in vitro (P < 0.05). CONCLUSION: BBOP delays puberty onset by increasing oxidative stress and apoptosis in Leydig cells in rats. UNLABELLED The graphical abstract is available on the website www.besjournal.com.

The present study was aimed to investigate the role and mechanism of glutaminolysis of cardiac fibroblasts (CFs) in hypertension-induced myocardial fibrosis. C57BL/6J mice were administered with a chronic infusion of angiotensin II (Ang II, 1.6 mg/kg per d) with a micro-osmotic pump to induce myocardial fibrosis. Masson staining was used to evaluate myocardial fibrosis. The mice were intraperitoneally injected with BPTES (12.5 mg/kg), a glutaminase 1 (GLS1)-specific inhibitor, to inhibit glutaminolysis simultaneously. Immunohistochemistry and Western blot were used to detect protein expression levels of GLS1, Collagen I and Collagen III in cardiac tissue. Neonatal Sprague-Dawley (SD) rat CFs were treated with 4 mmol/L glutamine (Gln) or BPTES (5 μmol/L) with or without Ang II (0.4 μmol/L) stimulation. The CFs were also treated with 2 mmol/L α-ketoglutarate (α-KG) under the stimulation of Ang II and BPTES. Wound healing test and CCK-8 were used to detect CFs migration and proliferation respectively. RT-qPCR and Western blot were used to detect mRNA and protein expression levels of GLS1, Collagen I and Collagen III. The results showed that blood pressure, heart weight and myocardial fibrosis were increased in Ang II-treated mice, and GLS1 expression in cardiac tissue was also significantly up-regulated. Gln significantly promoted the proliferation, migration, mRNA and protein expression of GLS1, Collagen I and Collagen III in the CFs with or without Ang II stimulation, whereas BPTES significantly decreased the above indices in the CFs. α-KG supplementation reversed the inhibitory effect of BPTES on the CFs under Ang II stimulation. Furthermore, in vivo intraperitoneal injection of BPTES alleviated cardiac fibrosis of Ang II-treated mice. In conclusion, glutaminolysis plays an important role in the process of cardiac fibrosis induced by Ang II. Targeted inhibition of glutaminolysis may be a new strategy for the treatment of myocardial fibrosis.
