BACKGROUND:Agomelatine is a clinically proven treatment for neuropsychiatric symptoms,such as anxiety and depression.Furthermore,our previous study has demonstrated that agomelatine ameliorates cognitive behaviors,hippocampal synaptic plasticity,and brain pathology in a mouse model of Alzheimer's disease.However,it remains unclear whether agomelatine can improve anxiety and depression-like behaviors in Alzheimer's disease model mice. OBJECTIVE:To investigate the improving effects of agomelatine on anxiety-and depression-like behaviors in APP/PS1 transgenic mice and its underlying molecular mechanisms. METHODS:(1)Eighteen APP/PS1 transgenic mice were randomly divided into model control group(n=9)and model intervention group(n=9).Another wild-type mice were randomized into control group(n=9)and intervention group(n=9).Model intervention group and intervention group were intraperitoneally injected with 10 mg/kg agomelatine per day for 31 continuous days.Behavioral experiments,including the elevated cross maze and forced swimming tests,and mRNA sequencing of the hippocampus were then performed.(2)Mouse hippocampal neuronal cell lines(HT22)and brain microvascular endothelial cell lines(bEnd.3)were cultured and divided into four groups:blank group without any drug,drug group with 20 μmol/L agomelatine,model group with 10 μmol/L β-amyloid 1-42,and experimental group with 10 μmol/L β-amyloid 1-42+20 μmol/L agomelatine.After 24 hours of incubation,protein expression of S416p-tau and S9p-GSK3β in HT22 cells was detected by immunoblotting,and protein expression of low-density lipoprotein receptor-related protein 1 and glycosylation end-product receptor in bEnd.3 cells was detected by immunoblotting. RESULTS AND CONCLUSION:In the elevated plus maze test,the time spent in the open arms(P<0.01)and the entries into open arms(P<0.05)in the mice of model control group were evidently lower than those in the control group,whereas those were obviously increased in the model intervention group compared with the model control group(P<0.05).Forced swimming test results showed that the immobile time exhibited a marked increase in the model control group compared with the control group(P<0.05),but it was significantly decreased in the model intervention group compared with the model control group(P<0.05).Hippocampal tissue mRNA sequencing showed that agomelatine enhanced the expression of low-density lipoprotein receptor-related protein 1 in the hippocampus of APP/PS1 mice.Western blot analysis revealed that the level of S416p-tau in HT22 cells was higher in the model group than the blank group(P<0.05),while it was markedly decreased in the experimental group compared with the model group(P<0.05);the level of S9p-GSK3β in HT22 cells was higher in the drug group than the blank group(P<0.05)as well as higher in the experimental group than the model group(P<0.05).Moreover,the expression of low-density lipoprotein receptor-related protein 1 in bEnd.3 cells was higher in the experimental group than the model group(P<0.05).To conclude,agomelatine can alleviate anxiety-and depression-like behaviors in Alzheimer's disease mice by promoting the clearance of β-amyloid and phosphorylated tau.

Objective:To explore the genetic etiology and clinical phenotype of Feingold syndrome due to chromosome 2p24.3p24.2 microdeletion.Methods:The clinical data of a child admitted to Henan Provincial People′s Hospital in November 2021 and diagnosed as Feingold syndrome type 1 (FGLDS1) associated with chromosome 2p24.3p24.2 microdeletion were collected. The clinical and genetic variation characteristics of the patient were summarized, and 10 patients with chromosome 2p microdeletion reported until November 2022 were reviewed.Results:The boy was 12 years and 5 months old. He presented with backward physical development, motor development retardation, low intelligence, special body and facial appearance, finger developmental deformity and other manifestations, accompanied by hyperactivity and aggressive behavior, impulsive irritability, self-injury and other behavior problems. The proband showed normal chromosome karyotype; the genome-wide copy number variant sequencing and trio-whole exome sequencing revealed a 2.61 Mb deletion at chromosome 2p24.3p24.2 region, and 10 genes including MYCN gene (exons 1 to 3) in the deleted region.The same deletion was not found in either of his parents. The genetic features of 11 cases (including this case) with chromosome 2p microdeletion were summarized, all of whom had insufficient haploid dosage of the MYCN gene due to chromosome 2p microdeletion, and the clinical manifestations of these 11 patients matched the clinical diagnosis of FGLDS1. Conclusion:The proband is consistent with the clinical presentation of the typical Feingold syndrome, and the haploinsufficiency of the MYCN gene due to the microdeletion of chromosome 2 is the genetic etiology of the proband.

Objective:To observe the effects of acupuncture and moxibustion at Feishu(BL13)on inflammatory responses and intestinal short-chain fatty acids(SCFAs)in rats with asthma. Methods:Fifty-six Sprague-Dawley rats were randomly divided into a normal group(16 rats)and a modeling group(40 rats).Rats in the modeling group were subjected to establishing asthma models using ovalbumin(OVA).Model evaluation was conducted using 4 rats from each group.The remaining rats that successfully developed asthma were then randomly divided into a model group,an acupuncture group,and a moxibustion group,with 12 rats in each group.Rats in the acupuncture group received acupuncture treatments,and those in the moxibustion group received moxibustion treatments,both at Feishu(BL13)for 30 min.Following the treatments,the rats were exposed to atomization excitation with a 1%OVA solution for 20 min daily for 14 consecutive days.At the end of the experiment,inflammatory markers in the rats'peripheral blood were analyzed using a biochemical method.In addition,inflammatory cells in the bronchoalveolar lavage fluid(BALF)were counted using Wright-Giemsa staining.The lung tissue of rats was examined under a light microscope after staining with hematoxylin-eosin to observe morphological or pathological changes.Furthermore,real-time fluorescence quantitative polymerase chain reaction was utilized to measure the mRNA expression of inflammatory factors in the lung tissue.Lastly,the concentration of SCFAs in the rat's feces was determined using gas chromatography-hydrogen flame ionization. Results:The levels of eosinophils(Eos),neutrophils(Neu),and lymphocytes(Lym)in the peripheral blood,as well as Eos and Neu in the BALF,and the expression of interleukin(IL)-4,IL-5,IL-13,IL-33,and thymic stromal lymphopoietin(TSLP)mRNAs in the lung tissue were all found to be significantly increased(P<0.05 or P<0.01);the lung tissue structure displayed severe injuries;the levels of acetic acid,propionic acid,isobutyric acid,butyric acid,and valeric acid in the feces decreased significantly in the model group(P<0.05 or P<0.01).Compared with the model group,the peripheral blood levels of Eos,Neu,and Lym,as well as Eos in the BALF,and the mRNA expression levels of IL-4 and IL-5 in the lung tissue decreased significantly in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).This reduction was accompanied by alleviated pathological damage in the lung tissue.Additionally,there were significant increases in the levels of acetic acid,propionic acid,isobutyric acid,and butyric acid in the feces in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).In the acupuncture group,the expression levels of Lym in the BALF and IL-13 mRNA in the lung tissue decreased significantly(P<0.05 or P<0.01).In the moxibustion group,the mRNA expression levels of IL-33 and TSLP in the lung tissue also reduced significantly(P<0.05 or P<0.01).Furthermore,the level of valeric acid in the feces increased notably in the moxibustion group(P<0.01).Compared with the acupuncture group,it was found that the mRNA levels of IL-5 and IL-13 in the lung tissue,as well as the acetic acid level in the feces,were significantly higher in the moxibustion group(P<0.05 or P<0.01). Conclusion:Both acupuncture and moxibustion were effective in reducing abnormal inflammation and regulating intestinal SCFAs in asthma model rats.Acupuncture demonstrated superiority in inhibiting pro-inflammatory factors,particularly IL-5 and IL-13,while moxibustion exhibited better regulation on intestinal metabolites SCFAs,especially acetic acid.

Objective:To analyze the epidemiological characteristics of rabies in China from 2007 to 2023, and to provide reference evidence for tailoring strategies to facilitate the elimination of rabies in the country.Methods:Case data from 2007 to 2023 were obtained from China′s National Notifiable Infectious Disease Reporting Information System, and the spatial, temporal, and demographic features of cases were analyzed.Results:From 2007 to 2023, a total of 18 751 human rabies cases were reported in China, with an average annual incidence rate of 0.08 per 100 000. The average annual percentage change (AAPC) in incidence rate was -18.58% (95% CI: -21.32% to -15.75%, P<0.05), with three significant turning points in 2011, 2018, and 2021. Based on the trend of the epidemic, Chinese provinces can be roughly divided into five categories. The geographical range affected by rabies has decreased from 23 provinces and 984 counties (districts) in 2007 to 17 provinces and 101 counties (districts) in 2023. Since 2019, the high-incidence counties (districts) have been mainly concentrated in the southwestern part of Hunan, the southern part of Henan, and the western part of Anhui. Fourteen provinces have reported no cases for at least two consecutive years. Males (70.24%) and farmers (72.18%) were the main affected groups, and the proportion of cases aged 65 and above increased from 17.43% in 2007 to 36.07% in 2023. Conclusions:The incidence of rabies in China has changed from endemic in many areas to sporadic, with the remaining endemic regions mainly located in parts of the middle and lower reaches of the Yangtze River. The main vulnerable groups are middle-aged and elderly farmers. The current prevention and control measures can effectively curb the transmission of rabies, but the decline of cases has slowed down recently.
