BACKGROUND:The extracellular-regulated protein kinase 5(ERK5)signaling protein is essential for the survival of organisms,and resveratrol can promote osteoblast proliferation through various pathways.However,whether resveratrol can regulate osteoblast function through the ERK5 signaling protein needs further verification. OBJECTIVE:To explore the regulatory effect of ERK5 on the proliferation of MC3T3-E1 cells and related secreted proteins,and to further verify whether resveratrol can complete the above process by activating ERK5. METHODS:Mouse MC3T3-E1 preosteoblasts were treated with complete culture medium,XMD8-92(an ERK5 inhibitor),epidermal growth factor(an ERK5 activator),resveratrol alone,XMD8-92+EGF,and resveratrol+XMD8-92,respectively.Western blot assay was used to detect the expression of ERK5 and p-ERK5 proteins,proliferation-related proteins Cyclin D1,CDK4 and PCNA,and osteoblast-secreted proteins osteoprotegerin and receptor activator of nuclear factor-κB ligand in MC3T3-E1 cells of each group.The fluorescence intensity of ERK5,osteoprotegerin and receptor activator of nuclear factor-κB ligand in each group was detected by cell immunofluorescence staining,and cell proliferation was detected by EdU staining,respectively.The appropriate concentration and time of resveratrol intervention in MC3T3-E1 cells were determined by cell morphology observation and cell counting kit-8 assay. RESULTS AND CONCLUSION:The activation of ERK5 signaling protein could effectively promote the proliferation of MC3T3-E1 cells,up-regulate the osteoprotegerin/receptor activator of nuclear factor-κB ligand ratio.The appropriate concentration and time for resveratrol intervention in MC3T3-E1 cells was 5 μmol/L and 24 hours,respectively.Resveratrol could activate ERK5 signaling protein,thereby promoting osteoblast proliferation and up-regulating the osteoprotegerin/RANKL ratio.All these results indicate that resveratrol can promote the proliferation of MC3T3-E1 cells and up-regulate the osteoprotegerin/RANKL ratio by activating the ERK5 signaling protein.

Perceptual decision making refers to the process by which individuals make choices and judgments based on sensory information, serving as a fundamental ability for human adaptation to complex environments. While traditional research has focused on perceptual decision making in isolated contexts, growing evidence highlights the profound influence of social contexts prevalent in real-world scenarios. As a crucial factor supporting individual survival and development, social context not only provides rich information sources but also shapes perceptual decision making through top-down processing mechanisms, prompting researchers to recognize the inherently social nature of human decisions. Empirical studies have demonstrated that social information, such as others’ choices or group norms, can systematically bias individuals’ perceptual decisions, often manifesting as conformity behaviors. Social influence can also facilitate performance under certain conditions, particularly when individuals can accurately identify and adopt high-quality social information. The impact of social context on perceptual decisions is modulated by a variety of external and internal factors, including group characteristics(e.g., group size, response consistency), attributes of peers (e.g., familiarity, social status, distinctions between human and artificial agents), as well as individual differences such as confidence, personality traits, and developmental stage. The motivations driving social influence encompass three primary mechanisms: improving decision accuracy through informational influence, gaining social acceptance through normative influence, and maintaining positive self-concept. Recent computational approaches have employed diverse theoretical frameworks to provide valuable insights into the cognitive mechanisms underlying social influence in perceptual decision making. Reinforcement learning models demonstrate how social feedback shapes future choices through reward-based updating. Bayesian inference frameworks describe how individuals integrate personal beliefs with social information based on their respective reliabilities, dynamically updating beliefs to optimize decisions under uncertainty. Drift diffusion models offer powerful tools to decompose social influence into distinct cognitive components, allowing researchers to differentiate between changes in perceptual processing and shifts in decision criteria. Collectively, these models establish a comprehensive methodological foundation for disentangling the multiple pathways by which social context shapes perceptual decisions. Neuroimaging and electrophysiological studies provide converging evidence that social context influences perceptual decision making through multi-level neural mechanisms. At early perceptual processing stages, social influence modulates sensory evidence accumulation in parietal cortex and directly alters primary visual cortex activity, while guiding selective attention to stimulus features consistent with social norms through attentional alignment mechanisms. At higher cognitive levels, the reward system (ventral striatum, ventromedial prefrontal cortex) is activated during group-consistent decisions; emotion-processing networks (anterior cingulate cortex, insula, amygdala) regulate experiences of social acceptance and rejection; and mentalizing-related brain regions (dorsomedial prefrontal cortex, temporoparietal junction) support inference of others’ mental states and social information integration. These neural circuits work synergistically to achieve top-down multi-level modulation of perceptual decision making. Understanding the mechanisms by which social context shapes perceptual decision making has broad theoretical and practical implications. These insights inform the optimization of collective decision-making, the design of socially adaptive human-computer interaction systems, and interventions for cognitive disorders such as autism spectrum disorder and anorexia nervosa. Future studies should combine computational modeling and neuroimaging approaches to systematically investigate the multi-level and dynamic nature of social influences on perceptual decision making.

Objective To compare the clinical efficacy of intraoperative slide rail CT combined with C-arm X-ray assis-tance and just C-arm for percutaneous screw in the treatment of pelvic posterior ring injury.Methods A retrospective analysis was performed on the patient data of 76 patients with posterior pelvic ring injury admitted to the Department of Orthopedic Trauma from December 2018 to February 2022.Among them,39 patients in the CT group were treated with C-arm combined with slide rail CT-assisted inline fixation including 23 males and 16 females with an average age of(44.98±7.33)years old;and the other 37 patients in the C-arm group were treated with intraline fixation treatment under only C-arm fluoroscopy in-cluding 24 males and 13 females with an average age of(44.37±10.82)years old.Among them,42 patients with anterior ring fractures were treated with percutaneous inferior iliac spines with internal fixation(INFIX)or suprapubic support screws to fix the anterior pelvic ring.Postoperative follow-up time,operation time,complications of the two groups were compared.Results of Matta reduction criteria,Majed efficacy evaluation,the CT grading and the rate of secondary surgical revision were com-pared.Results The nailing time of(32.63±7.33)min in CT group was shorter than that of(52.95±10.64)min in C-arm group(t=-9.739,P＜0.05).The follow-up time between CT group(11.97±1.86)months and C-arm group(12.03±1.71)months were not statistically significant(P＞0.05).The postoperative complication rates between two groups were not statistically significant(x2=0.159,P＞0.05).Results of Matta reduction criteria(Z=2.79,P＜0.05),Majeed efficacy evaluation(Z=2.79,P＜0.05),CT grading(Z=2.83,P＜0.05)in CT group were better than those in C-arm group(P＜0.05);the secondary surgical revision rate in the CT group was significantly lower than that in the C-arm group(x2=5.641,P＜0.05).Conclusion Compared with traditional C-arm fluoroscopy,intraoperative slide rail CT combined with C-arm assisted percutaneous sacroiliac joint screw placement surgery has the characteristics of short operation time,high accuracy and safety,and significant decrease in postoperative sec-ondary revision rate,and is one of the effective methods for re-establishing the stability of the posterior ring of pelvic fracture.

Objective To explore the magnetic resonance imaging(MRI)manifestations of acute cerebral infarction(ACI)and the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2),cystatin C(Cys C)and short-term prognosis.Methods A total of 110 ACI patients admitted to the department of neurology in our hospital from January 1,2022 to January 1,2023 were selected as the study objects.The clinical data and multimodal MRI were collected,and the serum Lp-PLA2 and Cys C levels of patients were detected.The patients were divided into the good prognosis group and the poor prognosis group according to the modified Rankin scale(mRS)score 90 days after onset.The predictive value of MRI manifestations and Lp-PLA2 and Cys C levels for short-term poor prognosis was analyzed.Results There were statistically significant differences in the time from onset to admission,National Institute of Health Stroke Scale(NIHSS)score on admission,hypertension or diabetes,coronary heart disease or atrial fibrillation of patients between the good prognosis group and the poor prognosis group(P<0.05).The proportions of patients with ischemic penumbra,HV positive,cortical-subcortical infarction,large perforating branch infarction,small perforating branch infarction,bilateral anterior circulation infarction,posterior circulation infarction,anterior-posterior circulation infarction,middle cerebral artery(MCA)stenosis or occlusion,both internal carotid artery(ICA)and MCA stenosis or occlusion,posterior cerebral artery(PCA)or vertebral artery(VA)stenosis or occlusion and hemorrhage transformation in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).The Lp-PLA2 and Cys C levels of patients in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).Small penetrating branch infarction,posterior circulation infarction,anterior-posterior circulation infarction,MCA stenosis or occlusion,both ICA and MCA stenosis or occlusion,hemorrhage transformation,serum Lp-PLA2 and Cys C had certain predictive value for patients with short-term poor prognosis(P<0.05).Conclusion MRI manifestations(ischemic penumbra,HV positivity,different types of cerebral infarction,and vascular stenosis)and serum Lp-PLA2 and Cys C levels can predict the short-term prognosis of ACI patients and provide important reference for the formulation of clinical treatment plans.

This study was aimed at analyzing the changes in the cell proteome of HTR-8/Svneo human villous trophoblasts during infection with Listeria monocytogenes,to explore the mechanisms involved in L.monocytogenes infection of the placenta at the molecular level in host cells.Tandem Mass Tag(TMT)proteomics was used to compare the quantitative proteome be-tween the HTR-8/Svneo infection group and control group.The Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)databases were used to analyze enrichment in the molecular functions,biological processes,and metabolic pathways of differentially expressed proteins.A total of 76 285 peptides and 6 979 quantifiable proteins were identified.A total of 356 proteins showed significant differential expression:153 up-regulated and 203 down-regulated.The protein with the high-est fold change was microtubule motor protein(B4DYE2),and the protein with the lowest fold change was translation initia-tion factor 1(Q6IAV3).GO functional enrichment and KEGG metabolic pathway enrichment analyses indicated that the up-regulated proteins were involved primarily in biological processes and metabolic pathways such as the movement of microtubules and microfilament as well as autophagy,whereas the down-regulated proteins were involved mainly in primary metabolic pathways,such as carbon metabolism,nitrogen metabolism,amino acid biosynthesis,and nucleic acid metabolism,as well as ubiquitin mediated protein hydrolysis.In the process of infection of HTR-8/Svneo by L.monocytogenes,the basal metabolism of host cells may be significantly diminished,and the autophagy level may be high.The significant up-regulation of cell migration-inducing and hyaluronan-binding protein CEMIP(Q8WUJ3)suggested an important role of this protein in regulating the migration and invasion of trophoblast cells,thus causing adverse pregnancy outcomes.Our findings may provide new ideas for the study of the molecular mechanism of L.monocytogenes infection of the placenta.

Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People's Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS)rate was 46.01％and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3％and 61％,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4.ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.

Objective:To investigate the clinical and pathological characteristics of adrenocortical carcinoma (ACC) patients, and to analyze the correlation between clinical features and Ki-67 index.Methods:Retrospectively analyze the clinical data of ACC patients admitted into Peking Union Medical College Hospital from January 1984 to January 2024. Inclusion criteria: ①The patient underwent puncture or surgery, and was diagnosed as ACC; or those who had typical manifestations of adrenocortical multi-band disorders, extremely high FDG uptake in the adrenal area and distant metastasis, and the diagnosis of ACC was considered after multidisciplinary consultation in our hospital; ②The patient had undergone thoracic, abdominal and pelvic CT scan, and could determine the size of the tumor and whether metastasis occurred. Exclusion criteria: ①without pathological diagnosis of ACC or no diagnosis of ACC without multidisciplinary consultation in our hospital; ②no records of symptoms, signs, examinations and other information at the time of initial diagnosis. The baseline data (age, gender, tumor side, etc.), clinical manifestations, endocrine examination, imaging and pathological examination results of the patients were collected, and the relationship between the maximum tumor diameter, the stage of the European Network for the Study of Adrenal Tumors (ENSAT), the functional status of the tumor, the maximum uptake value of 18F-FDG (SUVmax) and the Ki-67 index was analyzed. Results:A total of 164 patients were included in this study. There were 65 males and 99 females, with a male to female ratio of 1∶1.52. The median age at diagnosis was 48 (40, 58) years old. 71 tumors were located (43.29%) on the left side with 91 cases (55.49%) on the right side, and 2 cases (1.22%) on both sides. The median tumor diameter was 9 (7, 12) cm, of which 147 cases (147/158, 93.04%) were>5 cm. A total of 162 patients had ENSAT stages, including 9 stages Ⅰ(5.56%), 72 stage Ⅱ (44.44%), 51 stage Ⅲ (31.48%) and 30 stage Ⅳ(18.52%), respectively. Among the 154 cases with evaluable symptoms, 101 had no typical clinical manifestations and 53 patients had typical clinical manifestations. There were 41 cases (26.62%) of Cushing syndrome, 36 (23.38%) cases of abnormal sexual characteristics, and 19 cases (12.34%) of primary aldosteronism. 100 patients (64.94%) had abnormal endocrine examinations. The results of pathological examination showed 138 cases (90.20%) of traditional subtype, 13 cases (8.50%) of eosinophilic subtype, 1 case of mucinous type (0.65%) and 1 case of sarcomatoid ACC (0.65%). The detection rate of intravascular tumor thrombus was 14.63% (24/164), and the inferior vena cava and renal vein thrombus (10.37, 17/164) were the most common. The median Ki-67 index was 20% (10%, 40%), and 93.13% (122/131) had a Ki-67 index higher than 5%. The median Ki-67 index of ENSAT stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 20%(10%, 35%), 15%(10%, 30%), 30%(20%, 60%), 30%(20%, 60%), respectively. Compared with stage Ⅱ, ENSAT stage Ⅲ ( P=0.0007) and stage Ⅳ ( P=0.0011) ACC had a higher Ki-67 index; there was no statistical correlation between Ki-67 index and tumor maximum diameter, SUVmax of the primary lesion, and functional status of tumor (all P>0.05). Conclusions:ACC has the characteristics of late staging upon initial diagnosis, low proportion of patients with typical symptoms, and low detection rate of intravascular tumor thrombus. ENSAT stage was correlated with the Ki-67 index. Compared with Stage Ⅱ, ENSAT stage Ⅲ and Ⅳ ACC had a higher Ki-67 index.

Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.

Four cases of multiple lung metastases were treated with radiotherapy combined with mitotane. According to the postoperative pathological examination results, record the pathological Weiss score and MIB-1. Analyze the correlation between MIB-1 and clinical pathological indicators and prognosis of patients. Results:There were 59 cases in the ACC group, 35 cases of R0 resection, 19 cases of R1 resection and 5 cases of R2 resection.The postoperative pathological examination showed an average weight of approximately (371±52)g, with 42 cases having a tumor mass ≤ 300 g and 17 cases having a tumor mass>300 g. The positive rate of MIB-1 in the control group was 1% to 5%, while the positive rate of MIB-1 in the ACC group was greater than 5%, the difference between the two groups was statistically significant ( P<0.01). 53 patients diagnosed with capsule invasion, capsule rupture, intravascular tumor thrombus, and MIB-1>10% through postoperative pathological examination were treated with tumor bed radiotherapy and mitotan medication, followed by second-line combination immunotherapy and EDP chemotherapy. The 5-year survival rates of ACC patients with different tumor stages were 65% in stage Ⅰ, 58% in stage Ⅱ, 38% in stage Ⅲ, and less than 5% in stage Ⅳ. The total survival time of the two subgroups with low and high staging was 3.6 years and 1.1 years respectively ( P=0.003), while the disease-free survival time of the two groups was 25 months and 11 months, respectively ( P=0.011). R0 resection has a better prognosis than R1 and R2 resection, and its five-year survival rate is higher ( P=0.03). The 5-year survival rates of R0, R1, and R2 groups were 61%, 31%, and 17%, respectively( P=0.030).Survival analysis showed that adrenal cortical cancer patients with MIB-1 greater than 10% had a worse prognosis, with 5-year OS of 17% and 32% for both groups, respectively ( P=0.021). The Weiss score of the ACC group was (7±2). There were 21 cases in the Weiss score 3-5 group and 38 cases in the 6-9 group, the 5-year survival rates of the two groups were 62% and 19%, respectively ( P=0.017). Conclusions:MIB-1 can serve as an auxiliary diagnostic and prognostic indicator, and high expression of MIB-1 can contribute to the early diagnosis and determination of treatment strategies for ACC.
