Objective To investigate the effect of vascular endothelial function on restenosis after carotid artery stenting(CAS).Methods A total of 236 patients with carotid artery stenosis who received CAS in Jinhua People's Hospital from January 2019 to December 2022 were selected as study objects.According to whether in-stent restenosis(ISR)occurred during follow-up,they were divided into ISR group(n=41)and non-ISR group(n=195).Blood lipid indexes[low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)],vascular endothelial indexes[endothelin-1(ET-1),von Willebrand factor(vWF),vascular endothelial growth factor(VEGF),vascular cell adhesion molecule 1(VCAM-1),thromboxane B2(TXB2),endothelial nitric oxide synthase(eNOS),nitric oxide(NO)],inflammatory factors[tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),C-reactive protein(CRP)]and oxidative stress indexes[malondialdehyde(MDA),glutathione peroxidase(GSH-Px),superoxide dismutase(SOD)]were collected and compared between two groups.Transcriptome sequencing was performed on peripheral blood of ISR group and non-ISR group.Multivariate Logistic regression was used to analyze the independent influencing factors of ISR after CAS.Results The levels of TC,TNF-α,CRP,IL-6,MDA,ET-1,vWF,TXB2 and VCAM-1 in ISR group were significantly higher than those in non-ISR group(P＜0.01),and the levels of HDL-C,SOD,GSH-Px,NO,eNOS and VEGF in ISR group were significantly lower than those in non-ISR group(P＜0.01).Transcriptome differential gene enrichment analysis showed that the signaling pathways such as inflammatory response activation,oxidative stress response,and endothelial cell dysfunction were significantly enhanced in ISR group.Multivariate Logistic regression analysis showed that TNF-α,IL-6,ET-1,vWF,VEGF,SOD,and GSH-Px were independent influencing factors for ISR after CAS(P＜0.05).Conclusion Inflammatory factors,oxidative stress indexes and vascular endothelial function jointly promoted the occurrence and development of ISR after CAS in patients with carotid artery stenosis.TNF-α,IL-6,ET-1,vWF,VEGF,SOD,GSH-Px were independent risk factors for ISR after CAS.

Depressive disorder ranks as a major bur-den of disease worldwide,yet the current antidepressant medications are limited by frequent non-responsiveness and significant side effects.The lateral septum(LS)is thought to control of depression,however,the cellular and circuit substrates are largely unknown.Here,we identified a subpopulation of LS GABAergic adenosine A2A receptors(A2AR)-positive neurons mediating depres-sive symptoms via direct projects to the lateral habenula(LHb)and the dorsomedial hypothalamus(DMH).Activa-tion of A2AR in the LS augmented the spiking frequency of A2AR-positive neurons leading to a decreased activation of surrounding neurons and the bi-directional manipula-tion of LS-A2AR activity demonstrated that LS-A2ARs are necessary and sufficient to trigger depressive pheno-types.Thus,the optogenetic modulation(stimulation or inhibition)of LS-A2AR-positive neuronal activity or LS-A2AR-positive neurons projection terminals to the LHb or DMH,phenocopied depressive behaviors.Moreover,A2AR are upregulated in the LS in two male mouse mod-els of repeated stress-induced depression.This identifica-tion that aberrantly increased A2AR signaling in the LS is a critical upstream regulator of repeated stress-induced depressive-like behaviors provides a neurophysiological and circuit-based justification of the antidepressant poten-tial of A2AR antagonists,prompting their clinical transla-tion.

Objective:To explore the effect of progressive focusing-based interview combined with standardized stoma nursing in patients with enterostomy.Methods:From June 2019 to June 2021, 150 patients with enterostomy admitted to Lishui Central Hospital were selected by convenience sampling method as the research objects.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .

Clostridioides difficile is a key pathogen of antibiotic related diarrhea and hospital associated infection, causing several outbreaks in Europe and North Americans and resulting in severe disease burden. However, the standardized diagnostic principle and detection specifications in C. difficile infection (CDI) survey are limited in China, and the infection rate and disease burden of CDI in China are unclear. Therefore, National Institute for Communicable Disease Control and Prevention,National Institute for Communicable Disease Control and Prevention, Chinese Center for Disease Control and Prevention, together with another 11 institutions, draft the group standard entitled "Diagnosis of Clostridium difficile infection (T/CPMA 008-2020)" of Chinese Preventive Medicine Association. Based on the principle of "legality, scientificity, advancement, and feasibility", this standard clarifies risk factors, diagnosis principles, diagnoses and differential diagnoses in order to improve the accuracy of CDI diagnosis in clinical practice, guide the surveillance for CDI, and understand the infection rate and disease burden of CDI in China .

ObjectiveTo investigate the characteristics of polysomnography （PSG） in depression patients complicating moderate-to-severe obstructive sleep apnea hypopnea syndrome （OSAHS）. MethodsA retrospective analysis was conducted on the outpatients， inpatients and physical examination population who completed overnight PSG monitoring in the sleep medicine center of Suzhou Guangji Hospital from December 2017 to October 2019. Four groups of subjects were finally enrolled， including depression patients with moderate-to-severe OSAHS （n=31）， depression patients without OSAHS （n=79）， moderate-to-severe OSAHS patients （n=96） and normal control group （n=32）. The sleep process related indicators （total sleep time， sleep latency， number of awakenings）， sleep structure related indicators （N1， N2， N3， percentage of REM sleep， REM latency， REM sleep duration）， sleep-related respiratory variables （oxygen reduction index） and other polysomnographic parameters of the four groups were compared. ResultsIn terms of sleep process， the total sleep time， sleep latency and number of awakenings yielded significant differences among the four groups （F=2.874， 3.959， 12.291， P<0.05 or 0.01）. In terms of sleep structure， the percentage of total sleep time in N2 and N3 stages demonstrated significant differences among the four groups （F=13.885， 48.013， P<0.01）. The REM latency， REM sleep duration and percentage of REM sleep manifested significant differences among the four groups （F=41.492， 11.827， 10.552， P<0.01）. In terms of sleep-related respiratory variables， the oxygen reduction index exhibited significant differences among the four groups （F=170.585， P<0.05）. ConclusionDepression patients complicating moderate-to-severe OSAHS suffer from severe sleep process and structural disturbances， accompanied by quite frequent and severe sleep-related respiratory events.

Objective To investigate radiation-induced carotid and cerebral vascular injury and its relationship with radiation-induced temporal lobe necrosis in nasopharyngeal carcinoma (NPC) patients.Methods Fifty-eight NPC patients with radiation-induced temporal lobe necrosis (TLN) were recruited in the study.Duplex ultrasonography was used to scan bilateral carotid arterials to evaluate the intima-media thickness (IMT) and occurrence of plaque formation.Flow velocities of bilateral middle cerebral arteries (MCAs),internal carotid arteries (ICAs) and basal artery (BA) were estimated through Transcranial Color Doppler (TCD).The result were compared with data from 33 patients who were free from radiation-induced temporal lobe necrosis after radiotherapy and 29 healthy individuals,to study the relationship between IMT,occurrence of plaque and ventricular diastolic dysfunction.Results Significant differences in IMT,occurrence of plaques of ICAs and flow velocities of both MCAs and ICAs were found between patients after and healthy individuals (t =18.624,8.221,P ＜0.05;x2 =17.886,P ＜0.05;t =14.367,10.112,P ＜0.05).IMT had positive correlation with post radiation interval (r =0.368,P =0.049).IMT or incidence of plaques may be related to dose of radiotherapy,course of treatment and T stage (x2 =-17.635,12.006,-3.125,P ＜ 0.05).Compared with result from patients without radiation-induced TLN,the mean IMT was significantly thicker in patients with TLN (t =10.208,P ＜ 0.05).Plaques were more common in patients with TLN than patients without TLN (x2 =13.118,P ＜0.05).In addition,flow velocities of MCAs and ICAs in patients with TLN were much faster (t =5.011,5.035,P ＜ 0.05).Among patients with unilateral TLN,flow velocity of MCAs was significantly different between ipsilateral and contralateral sides to the lesion (t =18.362,P ＜ 0.05).Conclusions Thickening of IMT,occurrence of plaque formation and hemodynamic abnormality are more common in patients after radiotherapy,especially in those with TLN,compared with healthy individuals.

β-Catenin plays a critical role in cartilage formation and development. To further understand the role of β-catenin in osteoarthritis (OA) development in temporomandibular joint (TMJ), we have generated β-catenin conditional activation mice (β-cat(ex3) ) by breeding Agc1-CreER mice with β-catenin mice. Results of histologic analysis showed the progressive TMJ defects in 3- and 6-month-old β-cat(ex3) mice (tamoxifen induction was performed at 2 weeks of age), including decreased chondrocyte numbers in the superficial layer associated with less Alcian blue staining, increased numbers of hypertrophic chondrocytes in deep layers, and rough articular surface. Compared to the TMJ phenotype of β-cat(ex3) mice, β-cat(ex3) mice showed much severe morphological defects in the superficial layer of TMJ. This may reflect that Agc1-CreER mice could efficiently target cells in the superficial layer of TMJ. Results of immunostaining showed significantly increased expression of MMP13, Col-X, Adamts4, and Adamts5 in TMJ of β-cat(ex3) mice. Results of proliferating cell nuclear antigen (PCNA), Ki67, and terminal deoxinucleotidyl transferase-mediated dUTP-fluorescein nick end labeling (TUNEL) staining further demonstrated that cell proliferation was decreased and cell apoptosis was increased in condylar cartilage of β-cat(ex3) mice. Our findings indicate that abnormal upregulation of β-catenin in TMJ leads to defects assembling to OA-like phenotype, further demonstrating that β-catenin plays a critical role in TMJ pathogenesis.
