ObjectiveTo investigate the possible mechanism of Shenfuhuang Formula （参附黄配方） in prevention and treatment of epsis-associated encephalopathy from the perspective of brain genomics. MethodsC57BL/6 mice were randomly divided into sham surgery group， sepsis group， and Shenfuhuang group， with 20 mice in each group. The sepsis group and Shenfuhuang group were induced to develop sepsis by cecal ligation and puncture （CLP） procedure. At 4 hours after modelling， Shenfuhuang group were gavaged with 2.5 g/（kg·d） of Shenfuhuang Formula， 0.5 ml each time， at 12 hours intervals， for a total of 4 times after modelling. Sepsis group and sham surgery group were given 0.5 ml of purified water orally. At 48 hours after modeling， the transcriptome sequencing was used to explore the differential gene expression in the effects of Shenfuhuang Formula on the brain regions of septic mice， and real-time PCR and ELISA were later used to further validate the differential gene and proteins expression. ResultsA total of 4605 genes were differentially expressed in Shenfuhuang group compared with sepsis group， of which 2353 genes were up-regulated and 2252 genes were down-regulated. According to the results of previous publications， six key genes were screened， including serine/threonine-protein kinase （Nek1）， myelin-associated glycoprotein （Mag）， endothelial cell-specific tyrosine kinase receptor （Tek）， a disintegrin and metalloproteinase with thrombospondin motifs 20 （Adamts20）， lymphocyte antigen 86 （Ly86）， and E3 ubiquitin-protein ligase （Traip）. Further genetic and protein validation revealed that， compared to the sham surgery group， the mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip in the brain tissue of septic mice significantly reduced （P＜0.05）. In comparison to the sepsis group， Shenfuhuang group showed significantly increased mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip （P＜0.05）. ConclusionThe potential therapeutic targets of Shenfuhuang Formula for treating sepsis-associated encephalopathy may be related to the Nek1， Mag， Tek， Adamts20， Ly86， and Traip genes and their encoded proteins.

Objective To develop a risk assessment scale for immune checkpoint inhibitor (ICI)-associated myocarditis based on multidisciplinary collaboration, and to evaluate its diagnostic performance. Methods Based on multidisciplinary cooperation, integrating clinical experience from oncology and cardiology, literature data, and patient conditions, a risk assessment scale for ICI-associated myocarditis was developed. A total of 101 patients with malignancies who received immunotherapy at Zhongshan Hospital, Fudan University, from October 2020 to October 2024 were included as the validation cohort. Patients were stratified into low-risk (0-1 point), medium-risk (2-4 points), and high-risk (≥5 points) groups based on their scale scores. The association between pretictive risk stratifications and actual assessment results was assessed using the Cox proportional hazards regression model. The predictive value of the scale for ICI-associated myocarditis was evaluated using receiver operating characteristic (ROC) curve. Agreement between the scale scores and actual assessment results was assessed using Cohen’s Kappa coefficient. Results Based on the scale pretictive results, 28(27.7%), 8(7.9%), 65(64.4%) patients were at low risk, medium risk, and high risk for ICI-related myocarditis, respectively; however, 46(45.5%), 8(7.9%), 47(46.5%) were at low risk, medium risk, and high risk actually. Kaplan-Meier survival analysis showed that the cumulative incidence of ICI-related myocarditis in the high-risk group was significantly higher than that in the medium- and low-risk groups (P＜0.05). In the multivariable-adjusted Cox proportional hazards model, the ICI-related myocarditis risk in high-risk group was about 4 times that in the low-risk group. ROC curve analysis demonstrated that the average area under the curve (AUC) for predicting ICI-related myocarditis was 0.81, with an accuracy of 0.74. The Cohen’s Kappa coefficient was 0.55, indicating moderate agreement. In the actual high-risk group, no patient was predicted to be at low risk; in the actual low-risk group, 16 patients were predicted to be at high risk. Conclusions This risk assessment scale for ICI-associated myocarditis shows high predictive performance. It provides oncologists with a simple yet effective multidisciplinary diagnostic reference tool, potentially enhancing early identification of ICI-associated myocarditis.

Objective To investigate the effects of MCSO on physiological behavior and antioxidant index in D.melanogaster.Methods One-day-old wild type D.melanogaster was divided into control group,0.25％,0.5％,1％,2％and 4％dose groups,as well as male and female groups.The control group was exposed to the base medium,and each dose group was exposed to the MCSO medium added with 0.25％,0.5％,1％,2％and 4％concentrations,respectively.The optimal dosage concentration and time of administration were investigated by climbing experiment.Then the flies were divided into control group,model group and MCSO group.The model group was established by depriving the flies of sleep through repeated nocturnal light stimulation.Period of drug treatment,appetite test,negative geotaxis ability test,stress test,olfactory memory test,and sleep-wake rhythm detection were used to explore the effects of MCSO on their physiological behavior.The activities of super oxidase dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)were detected by enzyme-linked immunosorbent assay.Results MCSO enhanced the locomotory ability of 30-day-old D.melanogaster(P＜0.01),increased the activity of SOD and CAT(P＜0.01),and decreased the concentration of MDA(P＜0.01).Improve olfactory memory of senile fruit flies.After sleep deprivation,the night sleep time of female Drosophila model group was reduced(P＜0.05),and that of male Drosophila model group was reduced(P＜0.01).After feeding MCSO,the night sleep time of female drosophila model group was extended(P＜0.05),and that of male drosophila model group was extended(P＜0.01).Conclusions MCSO had a certain antioxidant effect,prolonging the sleep time and improving the olfactory memory of sleep-deprived Drosophila.

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.

Objective:To report a case of Kufor-Rakeb syndrome caused by novel ATP13A2 mutation, collect the cases related to ATP13A2 gene mutation published in recent years, summarize the clinical manifestations of the disease, and broaden the clinical diagnostic thinking. Methods:The clinical manifestations of a newly diagnosed patient with Kufor-Rakeb syndrome caused by ATP13A2 gene mutation admitted to Zhongda Hospital, Southeast University on November 26, 2021, were summarized. The related cases of ATP13A2 mutation published from January 2000 to December 2021 were searched through the PubMed and CNKI databases using the keywords "ATP13A2" and "Parkinson′s disease". The onset age, clinical symptoms, family history, genetic testing, and levodopa responsiveness results of the patients were collected. Results:The patient is a 52-year-old female with the main clinical symptoms of static tremor and bradykinesia. Physical examination showed a gear like increase in muscle tension in the right upper limb, involuntary shaking of the right hand and slow movement. She had good responsiveness to levodopa, and the magnetic resonance imaging and susceptibility weighted imaging of the head showed a lack of clear observation of bilateral black matter swallowtail sign. Whole exome sequencing showed that mutations c.3010A>G (p.S1004G) and c.1195+5G>A (splice) were found in the ATP13A2 gene, both of which were not reported. The c.3010A>G (p.S1004G) mutation originated from the mother, and the c.1195+5G>A (splice) mutation originated from the father. In the retrospective literature review, a total of 10 cases were collected, with onset ages ranging from 18 months to 24 years. Among them, 4/10 patients′ parents married close relatives, and the clinical manifestations were mainly motor symptoms of Parkinson′s disease. In addition, 5/10 patients had cognitive dysfunction, and 3/10 patients had mental symptoms. And demonstrations of most patients′ magnetic resonance imaging were normal in the early stage of the disease, and as the disease progressed, some patients′ imaging results showed specific changes, such as whole brain atrophy and changes in the corpus callosum. Meanwhile, 8/10 patients showed good responsiveness to levodopa. Conclusions:Kufor-Rakeb syndrome is a special type of adolescent levodopa responsive Parkinson′s disease caused by ATP13A2 mutation, which is an autosomal recessive disorder. In addition to motor symptoms such as static tremor and bradykinesia, its clinical manifestations may also be accompanied by non motor symptoms such as cognitive and psychiatric disorders. The disease responds well to treatment with levodopa.

Age-related macular degeneration (AMD) is one of the leading irreversible causes of blindness in China. The pathogenesis of AMD is not fully understood at present. Under various stress conditions, cellular senescence is activated, characterized by telomere shortening, mitochondrial dysfunction, DNA damage, and the release of various senescence-related secretory phenotype factors. Senescence is implicated in the pathogenesis of AMD through multiple pathways, contributing to chronic inflammation and the onset and progression of AMD. Mechanisms such as oxidative stress, lipofuscin, β amyloid protein and the membrane attack complex have become hotspots of study in the pathogenesis of AMD. The cyclic guanosine phosphate - adenosine synthase - interferon stimulating factor synthase-stimulator of interferon gene pathway has emerged as a critical signaling pathway in the early development of AMD, providing direction for further research on AMD. Currently, senolytics, selective agents targeting the induction of senescent cell apoptosis, show significant potential in the treatment of AMD. The integration of new technologies with cellular senescence may offer a novel approach to AMD treatment, and intervening in the AMD treatment through anti-cellular senescence pathways holds promising prospects.
