Objective To describe the epidemiological characteristics, investigation and treatment process of the first monkeypox cluster outbreak in Wuhan, and to provide reference for the prevention and control of monkeypox cluster outbreak in the future. Methods Field epidemiological investigation was conducted on the cases, and throat swabs, anal swabs, shingles fluid, whole blood, and serum samples were collected from the cases. Subsequently, real-time fluorescence quantitative polymerase chain reaction was employed for the detection of monkeypox virus nucleic acid and subsequent gene sequencing. Results Two cases had a high-risk exposure behavior in a hotel in Wuhan on June 2, 2023. The first case exhibited the emergence of beige papules on June 5 and sought medical treatment at a tertiary hospital in Wuhan on June 11. The Chinese Center for Disease Control and Prevention conducted tests on herpes fluid samples, which yielded positive results for the presence of monkeypox virus nucleic acid. Genetic sequencing analysis revealed that the infecting strain of the monkeypox virus in this case belonged to the West African clade B.1. Conclusion Based on epidemiological investigation and laboratory results, this monkeypox cluster outbreak may be caused by latent men with men sexual transmission. Monkeypox has the risk of both overseas importation and local transmission in our country. It is very necessary to detect, report and deal with monkeypox outbreak early.

Objective A serum proteomic approach was used to explore the targets of action of Peitu Qingxin Granules(composed of Rhizoma Atractylodis Macrocephalae,Forsythiae Fructus,Imperatae Rhizoma,Pseudostellariae Radix,etc.)in the treatment of atopic dermatitis.Methods Five patients with atopic dermatitis were selected and treated with Peitu Qingxin Granules for 12 weeks,and five healthy volunteers were used as controls.The clinical core evaluation indexes of atopic dermatitis patients after treatment,including Eczema Area and Severity Index/Scoring Atopic Dermatitis(EASI/SCORAD),Pruritus Score,Patient-Oriented Eczema Measure(POEM),and quality of life index,were assessed.Serum samples were examined using data-independent acquisition-mass spectrometry(DIA-MS)technology,and serum differential proteins between atopic dermatitis patients and healthy people,as well as serum differential proteins in atopic dermatitis patients before and after treatment with Peitu Qingxin Granules were screened according to P＜0.05 and Fold Change>1.2.GO function enrichment analysis and KEGG pathway enrichment analysis were performed on the differential proteins.Results(1)Compared with the pre-treatment period,the clinical core evaluation indexes of patients with atopic dermatitis,including the EASI/SCORAD,Pruritus Score,POEM,and quality-of-life index,were significantly improved after treatment,and the differences were all statistically significant(P＜0.05,P＜0.01).(2)A total of 28 differential proteins were analyzed in the healthy control group and atopic dermatitis group,of which 12 proteins expressions were increased and 16 proteins were decreased,including ALAD(δ-aminolevulinic acid dehydrogenase),LTA4H(leukotriene A-4 hydrolase),CA1(carbonic anhydrase 1),F11(coagulation factor XI),and LCP1(lymphocyte cytoplasmic protein 1),etc..The main signaling pathways involved are PI3K-AKT signaling pathway,lipids and atherosclerosis,ECM-receptor interaction,platelet activation,NF-κB signaling pathway,and neutrophil extracellular trap formation.(3)A total of 12 different proteins were analyzed in atopic dermatitis patients before and after treatment with Peitu Qingxin Granules,of which 8 proteins were increased and 4 proteins were decreased,including ALAD,FGA(fibrinogen α-chain),IGHV3-64D,and IGHV3-38.They were mainly involved in signaling pathways such as lipids and atherosclerosis,complement pathway,Staphylococcus aureus infection,NF-κB signaling pathway,fluid shear stress and atherosclerosis.(4)The expressions of three protein targets including ALAD,FGA and IGHV3-64D,were significantly down-regulated in patients with atopic dermatitis and significantly up-regulated after treatment with Peitu Qingxin Granules.Conclusion The differentially expressed proteins ALAD,FGA and IGHV3-64D may be the action targets of Peitu Qingxin Granules in the treatment of atopic dermatitis,which lays the foundation for further experimental validation.

Objective:To investigate the alterations of multilayer network and dynamic causal connectivity in patients with bilateral sudden sensorineural hearing loss.Methods:The hearing ability, neural-scale data and resting-state functional magnetic resonance imaging(fMRI)data of 60 patients with bilateral sudden sensorineural hearing loss from the Department of Otolaryngology and 60 healthy controls from Physical Examination Center, Nanjing First Hospital were collected from January 2022 to January 2024. Multilayer brain network analysis was computed to identify the nodes with abnormal switching rate. Then these abnormal nodes were used as regions of interest (ROIs) in the subsequent dynamic causal model analysis. The SPSS 26.0 software was used to analyze causal connectivity between two groups based on independent-sample Mann-Whitney U test. And Pearson correlation coefficients between fMRI results and clinical parameters were calculated. Results:Pure tone audiometry test showed that the left and right hearing thresholds of bilateral sudden sensorineural hearing loss were significantly higher than those of healthy controls( Z=-9.460, -9.462, both P<0.01). The score of depressive emotion in patients with bilateral sudden hearing loss was 6.00(2.00, 9.00).Multilayer brain network analysis showed that the switching rates in the left superior frontal gyrus (0.073(0.049, 0.102), Z=3.603, P<0.001), left anterior cingulate gyrus (0.077(0.044, 0.105), Z=3.189, P=0.001), right hippocampus (0.080(0.045, 0.116), Z=3.616, P<0.001), left para-hippocampal gyrus (0.080(0.043, 0.108), Z=3.577, P<0.001), left superior parietal gyrus (0.079(0.047, 0.103), Z=3.160, P=0.002), and right inferior parietal gyrus (0.078(0.043, 0.105), Z=3.396, P<0.001) in patients with bilateral sudden sensorineural hearing loss were lower that those in healthy controls. These six brain areas were used as ROIs to compute dynamic causal model analysis, and the results showed that the connection strength from left superior frontal gyrus to the left para-hippocampal gyrus in patients with bilateral sudden sensorineural hearing loss was significantly higher than that in healthy controls ( Z=-2.593, P<0.05). Additionally, enhanced connectivity from left superior frontal gyrus to the left para-hippocampal gyrus was positively correlated with duration of hearing loss ( r=0.376, P=0.003). Conclusions:Bilateral sudden sensorineural hearing loss patients have decreased switching rates in many brain areas, and the causal connectivity from left superior frontal gyrus to the left para-hippocampal gyrus is enhanced.

Background/Aims: Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Methods: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activitygroups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using surveylogistic regression and restricted cubic splines. Results: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Conclusions Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Subjective tinnitus refers to the subjective sound perception of patients in the absence of an external sound stimulus.Tinnitus patients are often accompanied by emotional disorders, such as depression and anxiety, which seriously affect the quality of life of patients.Therefore, understanding the mechanism underlying the occurrence of tinnitus emotional disorders can help relieve the pain of tinnitus.Tinnitus was considered a simple ear disease in the early stages, but with the progress of neuroimaging technology and the development of animal models, increasing attention has been given to the changes in the neural structure and function of tinnitus patients.As a powerful technique for in vivo investigation of neural activity in the brain, multimodal magnetic resonance has been widely used in the study of subjective tinnitus.By observing the changes of brain structure in subjective tinnitus patients, the neural mechanism of the occurrence and development of tinnitus has been explored.This article reviewed recent multimodal magnetic resonance imaging studies on the neuroimaging mechanisms of tinnitus with mood disorders, compared the differences in neural activity between subjective tinnitus patients and healthy people, and found that the limbic system, default mode network and other neural network abnormalities were closely related to the mood disorders of tinnitus.The application and development of multimodal magnetic resonance techniques in subjective tinnitus were also discussed to elucidate the neural mechanism of subjective tinnitus accompanied by mood disorders with the help of multimodal magnetic resonance techniques.

Ulcerative colitis（UC）is a disease characterized by chronic persistent inflammation of the colorectal mucosa. Its complex pathological mechanism is related to immune inflammation and enhanced apoptotic activity. The Janus kinase（JAK）/signal transducer and activator of transcription（STAT）is an important regulatory pathway in the body's physiological function, which can regulate the release of intestinal pro-inflammatory factors and induce apoptosis, resulting in colon tissue damage. In the condition of UC, the biological activities and expression levels of JAK and STAT increased, and the tissue inflammatory response and apoptosis rate increased, which led to the destruction of intestinal mucosal tissues. At present, in the treatment of UC, glucocorticoids and immunosuppressants are mainly employed to reduce intestinal inflammation. Although they can block the progress of UC to some extent, the adverse reactions are severe. A large number of studies have shown that traditional Chinese medicine（TCM） has significant advantages in the prevention and treatment of UC and can significantly reduce the recurrence rate of this disease. In recent years, plenty of studies have been carried out to explore the role of TCM in the treatment of UC by regulating the JAK/STAT pathway. The results have shown that the JAK/STAT pathway is the key target pathway of TCM in the treatment of UC. Based on the etiology and pathogenesis of deficiency and excess, TCM regulates the JAK/STAT pathway by clearing heat, drying dampness, cooling and activating blood, invigorating the spleen, warming the kidney, and performing both tonification and elimination to maintain the balance between pro-inflammatory factors and anti-inflammatory factors, weaken colonic inflammatory response, inhibit apoptosis, and play a role in the treatment of UC. The present study analyzed the mechanism and effect of TCM in intervening in UC by targeting the JAK/STAT signaling pathway and summarized the molecular mechanisms of different cytokines such as interleukin-6（IL-6）, IL-10, IL-23, microRNA（miRNA）-146a, and suppressors of cytokine signaling 2/3（SOCS2/3） on many family subtypes of the JAK/STAT signaling pathway to facilitate the comprehensive understanding of researchers on the mechanism of TCM on the JAK/STAT pathway in UC, which is expected to provide a theoretical basis for the treatment of UC and further drug development.

Objective:To investigate the local consistency of inferior colliculus and ventrolateral orbital cortex by resting-state functional magnetic resonance imaging (fMRI) in rats with noise induced deafness and its relationship with anxiety- and depression-like behavior.Methods:Twenty-four clean grade male four-weeks old SD rats were randomly divided into noise group and control group with 12 rats in each group.Rats in the noise group were exposed to 122 dB broadband strong noise for 2 hours to induce severe bilateral hearing loss, while rats in the control group were placed in a quiet environment. Hearing thresholds were assessed by auditory brainstem response (ABR) test. The open field test (OFT) was conducted to examine anxiety-depression related behavior, and the local consistency in the rat brain was evaluated by fMRI.SPM12 software was used to process fMRI data, and Pearson correlation analysis was conducted by SPSS 22.0 software to calculate the correlation between fMRI data and behavior.Results:The results of ABR showed that the full band hearing threshold of rats in the noise group was higher than that of rats in the control group ((85.417±6.463) dB, (20.083±8.853) dB, t=46.168, P<0.001). And compared with control group, the rats in the noise group showed obvious anxiety-depression-like behavior in the open field test, that was, low activity level.The results of OFT showed that the total distance ((39.912±5.696) m, (47.993±10.820)m, t=-2.289, P=0.032), average moving speed ((13.306±1.900)cm/s, (15.998±3.607)cm/s, t=-2.290, P=0.032) and standing times ((13.333±5.960), (23.500±7.323), t=-3.730, P=0.001) of the rats in the noise group were all lower than those in the control group. Compared with the control group, the local consistency of hypothalamus in the noise group was significantly enhanced, while the local consistency of ventrolateral orbital cortex was significantly reduced, and the abnormal neural activity was lateralized. The correlation analysis showed that the neural activity of the inferior colliculus was negatively correlated with the total distance of rats in the noise group moving in the open field( r=-0.691, P=0.013), while the neural activity of the ventrolateral orbital cortex was not significantly correlated with the anxiety-depression-like behavior in the open field. Conclusions:The neural activity of inferior colliculus is closely related to anxious-depression behavior in rats with noise-induced deafness, while the ventrolateral orbital cortex may be related with other behaviors.

Objective:To investigate the application value of fetal heart quantification (fetal HQ) in the evaluation of fetal heart size, morphology and function in fetuses with right ventricular outflow obstruction (RVOTO).Methods:Fifty-five fetuses diagnosed as RVOTO by fetal echocardiography in Sir Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University from April 2020 to February 2021 were selected. They were divided into simple pulmonary artery stenosis (PS) group and conus arteriosus malformation (CTD) group according to whether they were combined with other cardiovascular malformations. On the standard four chamber view, the end diastolic basal apical length (4CV length) and transverse width (4CV width) were obtained by fetal HQ analysis technique, and the cardiac global spherical index (4cv-gsi) was calculated. The left and right ventricles (LV and RV) were divided into 24 segments from the base to the apex. The endocardial curve was obtained by total HQ tracking. The 24 segment transverse width (ED), spherical index (SI), short axis shortening (FS) and its Z-score were calculated. The LV and RV of RVOTO fetuses were compared and analyzed from the aspects of heart size, morphology and function.Results:The 4CV length of RVOTO fetal heart was in the normal range, 4CV width increased in varying degrees, GSI decreased, and the whole heart showed spherical changes. In PS group, LV-ED was larger than that of RV and the difference was statistically significant in 5-24 segments( P<0.05). LV was more spherical than RV. There was no significant difference in ED between LV and RV in CTD group( P>0.05), and RV was more spherical than LV. Twenty-four segment FS decreased in different degrees in RVOTO fetal heart, and the decrease of RV was more obvious than that of LV. There was significant difference between the LV and RV in PS group from S5 to 19 ( P<0.05), and there was significant difference between the left and right ventricles in CTD group from S1 to 11 ( P<0.05). Conclusions:Fetal HQ can provide new insights of cardiac size, morphology and function in fetuses with RVOTO.
