OBJECTIVE: To observe the effects of electroacupuncture at the pterygopalatine region on nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3)-mediated pyroptosis and inflammatory factors in rats with allergic rhinitis (AR). METHODS: Twenty-four SD rats were randomly divided into a blank group, a model group, an acupuncture group and an electroacupuncture group, 6 rats in each group. Except for the blank group, OVA-induced AR model was established in the remaining groups. In the electroacupuncture group, the rats were treated with electroacupuncture at the bilateral pterygopalatine region, with disperse-dense wave, in frequency of 2 Hz/100 Hz and current of 0.5-1 mA, 15 min each time, once every other day, for 3 times. In the acupuncture group, the rats were treated with acupuncture at bilateral pterygopalatine region simply, without electrical stimulation. The rhinitis symptom score was observed, the pathomorphology of the nasal mucosa was observed by HE staining; the serum levels of OVA-specific immunoglobulin E (OVA-sIgE), interleukin (IL)-4, IL-6 and IL-1β were detected by ELISA; the mRNA expression of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC), cysteinyl aspartate specific proteinase-1 (caspase-1) and IL-18 in the nasal mucosa was detected by real-time PCR; the protein expression of NLRP3, ASC, caspase-1 and IL-18 in the nasal mucosa was detected by Western blot. RESULTS: Compared with the blank group, in the model group, the rhinitis symptom score was increased (P<0.01), the serum levels of OVA-sIgE, IL-4, IL-6 and IL-1β were increased (P<0.05), the nasal mucosa showed pathomorphology of inflammatory infiltration; the mRNA and protein expression of NLRP3, ASC, caspase-1 and IL-18 in the nasal mucosa was increased (P<0.05). Compared with the model group, in the electroacupuncture group, the rhinitis symptom score was reduced (P<0.01), the pathology of the nasal mucosa was improved; the serum levels of OVA-sIgE, IL-4, IL-6 and IL-1β were decreased (P<0.05); the mRNA and protein expression of NLRP3, ASC, caspase-1 and IL-18 in the nasal mucosa was decreased (P<0.05). CONCLUSION Electroacupuncture at the pterygopalatine region can exerting the anti-inflammatory effect by inhibiting NLRP3-mediated pyroptosis and inflammatory factor imbalance, thus alleviate rhinitis symptoms in AR rats.

BACKGROUND: Neuroticism has been associated with numerous health outcomes. However, most research has focused on a single specific disorder and has produced controversial results, particularly regarding mortality risk. Here, we aimed to examine the association of neuroticism with morbidity and mortality and to elucidate how neuroticism affects trajectories from a healthy state, to one or more neuroticism-related disorders, and subsequent mortality risk. METHODS: We included 483,916 participants from the UK Biobank at baseline (2006-2010). Neuroticism was measured using the Eysenck Personality Questionnaire. Three clusters were constructed, including worry, depressed affect, and sensitivity to environmental stress and adversity (SESA). Cox proportional hazards regression and multistate models were used. Linear regression was used to examine the association between neuroticism and immune parameters and neuroimaging measures. RESULTS: High neuroticism was associated with 37 non-overlapping diseases, including increased risk of infectious, cardiometabolic, neuropsychiatric, digestive, and respiratory diseases, and decreased risk of cancer. After adjustment for sociodemographic variables, physical measures, healthy behaviors, and baseline diagnoses, moderate-to-high neuroticism was associated with a decreased risk of all-cause mortality. In multistate models, high neuroticism was associated with an increased risk of transitions from a healthy state to a first neuroticism-related disease (hazard ratio [HR] [95% confidence interval (CI)] = 1.09 [1.05-1.13], P  <0.001) and subsequent transitions to multimorbidity (1.08 [1.02-1.14], P  = 0.005), but was associated with a decreased risk of transitions from multimorbidity to death (0.90 [0.84-0.97], P for trend = 0.006). The leading neuroticism cluster showing a detrimental role in the health-illness transition was depressed affect, which correlated with higher amygdala volume and lower insula volume. The protective effect of neuroticism against mortality was mainly contributed by the SESA cluster, which, unlike the other two clusters, did not affect the balance between innate and adaptive immunity. CONCLUSION This study provides new insights into the differential role of neuroticism in health outcomes and into new perspectives for establishing mortality prevention programs for patients with multimorbidity.

The oxytocin receptor (OXTR) has garnered increasing attention for its role in regulating both mature behaviors and brain development. It has been established that OXTR mediates a range of effects that are region-specific or period-specific. However, the current studies of OXTR expression patterns in mice only provide limited help due to limitations in resolution. Therefore, our objective was to generate a comprehensive, high-resolution spatiotemporal expression map of Oxtr mRNA across the entire developing mouse brain. We applied RNAscope in situ hybridization to investigate the spatiotemporal expression pattern of Oxtr in the brains of male mice at six distinct postnatal developmental stages (P7, P14, P21, P28, P42, P56). We provide detailed descriptions of Oxtr expression patterns in key brain regions, including the cortex, basal forebrain, hippocampus, and amygdaloid complex, with a focus on the precise localization of Oxtr⁺ cells and the variance of expression between different neurons. Furthermore, we identified some neuronal populations with high Oxtr expression levels that have been little studied, including glutamatergic neurons in the ventral dentate gyrus, Vgat⁺Oxtr⁺ cells in the basal forebrain, and GABAergic neurons in layers 4/5 of the cortex. Our study provides a novel perspective for understanding the distribution of Oxtr and encourages further investigations into its functions.

Objective:To explore the clinical features, histopathological morphology, and differential diagnosis of lymphoepithelioma-like carcinoma with abnormal expression of follicular dendritic cell markers.Methods:From 2020 to 2021, 4 cases of lymphoepithelioma-like carcinoma with abnormal expression of follicular dendritic cell markers diagnosed in Fujian Cancer Hospital (2 cases) and the Second Affiliated Hospital of Fujian Medical University (2 cases) were collected. Different ancillary procedures such as HE, special stains, immunohistochemistry, and in situ hybridization techniques were used to assess the histopathological features and immunophenotypes. The clinical data were collected and literature was reviewed.Results:All 4 cases of lymphoepithelioma-like carcinoma with abnormal expression of follicular dendritic cell markers were male. They were 32, 45, 67 and 39 years old, respectively. The main clinical manifestations were bloody phlegm, abdominal pain, fatigue and anorexia. The clinical stages at diagnosis were stage Ⅳ (3 cases) and stage Ⅱ (1 case). Cases 2 and 3 had two pathological examinations at different sites, with a total of six pathological examinations. The histomorphology showed singly scattered or nests of tumor cells in a background of abundant small lymphocytes. The tumor cells were enlarged and pleomorphic, some appeared polygonal with inconspicuous cell borders, and they were arranged in a syncytial pattern. There were megakaryocytes, multinucleated tumor cells, and a few spindle-shaped cells seen. Atypical mitosis was commonly noted. By immunohistochemistry, the tumor cells were positive for CKpan(5/6), CK8/18(4/4), CAM5.2(2/5), CK-H(0/4), CK-L(3/4), EMA(4/5), CK5/6(3/6), p63(1/6), p40(1/6), E-cadherin (4/6), SSTR2(6/6), PD-L1(5/5), LCA(0/6), vimentin(5/6), CD2 (6/6), CD23(6/6), CD35(5/6), CXCL-13(4/5) and D2-40(1/5). The Ki-67 proliferative index was 60%-95%. In situ hybridization for EBER were all positive (6/6). Special stain for reticulin showed positive staining surrounding nests of tumor cells.Conclusions:The expression of follicular dendritic cell markers in lymphoepithelioma-like carcinoma is very rare, which may be related to EBV infection. Occasionally, it can overlap with follicular dendritic cell sarcoma by morphology and immunophenotype, which can lead to misdiagnosis. Only by combining clinical information, morphological characteristics and immunophenotype can an appropriate diagnosis be made.

Objective:To explore the effectiveness of immersive virtual reality (VR)-guided core stability-assisted training in improving the balance of ischemic stroke survivors.Methods:Sixty-six hemiplegic ischemic stroke survivors were randomly divided into a conventional rehabilitation training group (CON) of 32 and an immersive VR-guided core stability-assisted training group (VR-TOT) of 34. In addition to basic internal medical treatment, the CON group underwent conventional rehabilitation therapy, while the VR-TOT group received VR-guided core stability-assisted training. Before and after 4 weeks of the treatments, the subjects′ balance was evaluated using the Fugl-Meyer balance scale. A three-dimensional force platform was used to collect the sway amplitude, sway speed, peripheral area and total trajectory length of the center of pressure COP of the bilateral plantar in the left-right and anterior-posterior directions while the subjects stood with the eyes open and closed.Results:After the treatments, the average Fugl-Meyer balance scores of both groups had improved significantly. In the eyes-open condition, after the treatment, there was a significant decrease in the average COP sway amplitude in the anteroposterior direction on the hemiplegic side among the CON group, as well as in both the mediolateral and anteroposterior directions on both sides in the VR-TOT group. The sway velocity in the anteroposterior direction on the hemiplegic side had decreased significantly in both groups, and the sway velocity in both the mediolateral and anteroposterior directions on the non-hemiplegic side had also decreased significantly. In the CON group the peripheral area on the non-hemiplegic side had decreased and the total trajectory length had shortened significantly. In the VR-TOT group there were significant decreases in the peripheral area on both sides and in the total trajectory length on both sides. Comparing the two groups after treatment, the peripheral area on the hemiplegic side in the VR-TOT group was significantly smaller. In the eyes-closed condition, the sway amplitude of the COP on the hemiplegic side in the anteroposterior direction and on the non-hemiplegic side in both the mediolateral and anteroposterior directions had decreased significantly in the VR-TOT group after the treatment. The average sway velocity had decreased significantly in the anteroposterior direction on the non-hemiplegic side in the CON group. In the VR-TOT group this was observed in the anteroposterior direction on the hemiplegic side and in both the mediolateral and anteroposterior directions on the healthy side. In the CON group the average peripheral area of the COP on the hemiplegic side had decreased, and the total trajectory length had shortened, both significantly. In the VR-TOT group, the peripheral area on the non-hemiplegic side had decreased significantly as well.Conclusions:Core stability-assisted training based on immersive virtual reality can effectively improve the balance of ischemic stroke survivors. It shows promise for clinical application.

Objective To explore the characteristics of latent profiles of ego depletion in patients with heart failure,and analyze the impacts of these profiles on patients' self-management behavior.Methods 280 heart failure patients who were hospitalized in a tertiary grade A hospital were conveniently selected in Nanjing from April to October 2024 as study subjects.The investigation utilized a general information questionnaire,the Ego-Depletion Scale for Heart Failure Patients,the Self-Management Scale of Heart Failure Patients,and the Chronic Disease Self-Efficacy Scale.The latent profile categories of ego depletion was explored in heart failure patients.Univariate analysis and multiple Logistic regression analysis were used to investigate the influencing factors of different latent profile categories and the impact of each category on patients' self-management levels.Results The ego depletion of 255 heart failure patients could be classified into 3 latent profiles:self-adaptive low depletion group(35.29％),symptom distressed moderate depletion group(43.53％),and social life change high depletion group(21.18％).Multiple Logistic regression analysis showed that residence,primary caregiver,education level,New York Heart Association cardiac function grade,and self-efficacy score were factors influencing the potential profile of ego depletion in heart failure patients(P＜0.05).The comparison of self-management scores among patients in different latent profiles of ego depletion showed statistically significant differences(P＜0.05).Conclusion The level of ego depletion in patients with heart failure is high with significant heterogeneity.Medical staff should pay attention to the heterogeneity and influencing factors of ego depletion in patients with heart failure in time,and develop personalized comprehensive intervention strategies to alleviate ego depletion and improve their self-management levels.

ObjectiveTo understand the prevalence of tobacco use among residents aged 15 years old and above in Jiading District of Shanghai, and to provide a scientific basis for formulating effective regional tobacco control policies. MethodsThe Probability Proportional to Size (PPS) sampling method was employed to select one neighborhood committee (village) from each of Jiading District’s 11 subdistricts as survey monitoring sites. From the household registry of each selected neighborhood committee (village), 50 residential households were randomly sampled, resulting in a total of 550 households surveyed. Within each selected household, one permanent resident aged 15 years old or above was randomly chosen to complete the questionnaire. The content covered general information, exposure to secondhand smoke, awareness of tobacco related health hazards, etc. Statistical analyses were performed using SPSS 27.0 software. ResultsA total of 550 questionnaires were distributed, with 549 valid responses collected, and the effective response rate was 99.82%. The survey findings revealed that in 2023, the current smoking rate among individuals aged 15 years old and above in Jiading District of Shanghai was 18.76%, with males accounting for 38.93% and females accounting for 2.62%. Male gender was identified as a relative factor for smoking (OR=34.108, 95%CI: 14.440‒80.722), whereas higher education attainment emerged as a protective factor against smoking (OR=0.388, 95%CI: 0.184‒0.820). Among non-smokers aged 15 years old and above in Jiading District, the secondhand smoke exposure rate was 46.86%, with statistically significant differences observed across different age groups and occupations (P<0.001). Restaurants exhibited the highest secondhand smoke exposure rate of 42.14%, followed by households bearing (36.79%). The overall awareness rate among individuals aged 15 years old and above in Jiading District regarding four smoking-related diseases, namely stroke, heart disease, lung cancer, and impotence, was 48.45%, while the awareness rate for three secondhand smoke-induced diseases, namely adult heart disease, pediatric pulmonary disease, and adult lung cancer, was 64.29%. ConclusionThere is still room for reduction in the prevalence of tobacco use among individuals aged 15 yeas old and above in Jiading District. The exposure to secondhand smoke is severe, and residents have low awareness of the harm of tobacco. Tobacco control law enforcement should be strengthened, smoke-free-home health education should be included in tobacco control efforts, and targeted health education should be carried out.

Objective To investigate the potential beneficial predictors for endovascular treatment(EVT)in case of acute anterior circulation large vessel occlusion with large-core infarction.Methods We made a retrospective inclusion of 92 patients with anterior circulation large vessel occlusion and core infarct volume ranging from 50 to 100 mL,who underwent EVT at Zhangzhou Municipal Hospital of Fujian Province from March 2018 to February 2021.All the patients were confirmed as anterior circulation large infarction and large infarct volume using computed tomography(CT),computed tomography angiography(CTA),and computed tomography perfusion(CTP)before EVT.All clinical and imaging data were collected to observe the postoperative recurrence rate,incidence of symptomatic intracranial hemorrhage(sICH),and functional prognosis 90 days.Then the patients were divided into favorable outcomes group(mRS≤3)and unfavorable outcomes group(mRS＞3)based on Rankin scores 90 days post-stroke.Univariate and multivariate Logistic analysis were conducted to analyze factors influencing the patients'prognosis.By combining the results of multivariate analysis,we constructed receiver operating characteristic(ROC)curves and identified the cut-off value to evaluate the predictive value of age for post-vascular treatment prognosis.Results Among the included patients,the postoperative revascularization rate(mTIICI≥2b)was 95％(88 cases),the rate of favorable outcomes at 90 days postoperatively(mRS≤3)was 32.61％(30 cases),the incidence of sICH was 13％,and the mortality rate was 31.5％.Compared with the unfavorable outcomes group,the favorable outcomes group had a younger age and a higher proportion of males.Multivariate analysis indicated that older age was an independent risk factor for adverse outcomes following endovascular treatment(OR=4.97,95％CI:1.78-13.90,P=0.002).The ROC curve indicated that the area under the curve was maximized at the age of 72.5 years(AUC=0.763,95％CI:0.661-0.864,P＜0.001).Its sensitivity and specificity was 0.565 and 0.833,respectively.Conclusion Age is an independent predictor of the prognosis of acute procirculatory large core stroke.Patients with large core infarction older than 72.5 years may not benefit from endovascular therapy,which needs to be confirmed by a multicenter large sample prospective randomized controlled trial.

Purpose To explore the clinicopathological features,diagnosis and differential diagnosis of mantle cell lymphoma(MCL)with aberrant expression of CD10.Methods 14 cases of MCL with aberrant expression of CD10 were analyzed using hematoxylin-eosin,immunohistochemical stains,in situ hybridization,and fluorescence in situ hy-bridization(FISH)techniques to observe the histological morphology,immunophenotype,and molecular genetic char-acteristics.The relevant literatures were reviewed.Results There were 11 males and 3 females,with a male-to-fe-male ratio of 11∶3.The age ranged from 49 to 80 years,with an average age of 64.4 years and a median age of 64 years.10 cases occurred in lymph nodes,1 case in the nasopharynx,1 case in the right colon,1 case in the right eye-lid,and 1 case in the right testis.According to the Ann Arbor staging system,8 cases were classified as stage Ⅳ and 5 cases as stage Ⅲ,and 1 case with undetermined staging.Histologically,there was diffuse effacement of the normal architecture by tumor cells infiltration.Transparent degenerate small blood vessels and scattered individual epithelial-like tissue cells could be observed in the background.Among them,8 cases(8/14,57.14％)were composed of uni-form small to medium-sized lymphocytes with slightly irregular nuclei,unevenly dispersed chromatin,inconspicuous nucleoli,and scant cytoplasm,along with observable mitotic figures.In 3 cases(3/14,21.43％),the tumor cells were large and markedly pleomorphic,with round or irregular nuclei,prominent nucleoli,frequent mitotic figures,and abundant pale cytoplasm.Tumor cells in 3 cases(3/14,21.43％)were resembling lymphoblasts,characterized by round nuclei,fine chromatin,inconspicuous nucleoli,frequent mitotic figures,and scant cytoplasm.Immunophenotyp-ically,CD21 staining showed residual follicular dendritic meshworks.The tumor cells were diffusely and strongly posi-tive for CD20(14/14),PAX5(7/7),CD5(14/14),Cyclin D1(14/14),SOX11(11/11),and BCL2(13/13),partially positive for BCL6(8/14,57.14％)and MUM1(6/9,66.67％),but negative for CD3(14/14)and CD23(14/14).Among 14 cases,10 cases were diffusely and strongly positive for CD10(10/14,71.43％),and 4 cases were partially positive for CD10(4/14,28.57％).The percentage of Ki67 index ranged from 10％to 90％.All cases were negative for EBER(8/8).FISH analysis was performed in 9 cases,among which 7 cases showed CCND1 gene rearrangement,another 2 cases failed to detect due to insufficient tissue samples.Bone marrow biopsy was performed in 13 cases,revealing involvement in 8 cases(8/13,61.54％)and no involvement in 5 cases(5/13,38.46％).Con-clusion MCL with aberrant expression of CD10 is very rare,which commonly exhibits a diffuse growth pattern and blastoid and pleomorphic variants.It often has a high Ki67 proliferation index and poorer prognosis,and should be dis-tinguished from other subtypes of CD1O-positive B-cell lymphomas.

Objective:To investigate the clinical manifestation, therapy, and prognosis of Susac syndrome and enhance the understanding of this disease.Methods:A case summary was made.The clinical data of two siblings with Susac syndrome treated at Children′s Medical Center, Peking University First Hospital in January 2024 were summarized.Reported cases of pediatric Susac syndrome were reviewed.Results:The onset of the disease in the two siblings was at the age of 3.00 and 6.75 years, with recurrent headaches, tinnitus, hearing loss and encephalopathy symptoms.Cranial magnetic resonance imaging showed multiple cerebral microbleeding and microinfarction lesions, " snowball like" in the corpus callosum and diffuse white matter edema in the brain.Audiometry revealed sensorineural hearing loss.In one case, ophthalmic fluorescein angiography revealed ischemic changes due to branch retinal artery occlusions.No pathogenic variants were detected in gene testing.This child was diagnosed with Susac syndrome, and the symptoms were improved after treatment with Corticosteroids and Rituximab.No relapse was observed during the 9-month follow-up.A total of 20 pediatric cases of Susac syndrome were retrieved, including 18 reported previously and 2 cases from this study.There were 2 boys and 18 girls, with the age of onset ranging from 2.5 to 17.0 years.The common initial symptoms included headache (19 cases), vertigo and tinnitus or hearing loss (9 cases), and vision impairment or visual field defect (4 cases). The symptoms were improved after immunotherapy.Conclusions:With a low incidence, Susac syndrome is rare in children and difficult to diagnose.There may be a genetic predisposition in such disease.Early diagnosis and immunotherapy can low the relapse and improve the prognosis.
