Mice are a core model organism in neuroscience and are undergoing a technological transition in whole-brain atlas construction,as researchers shift from traditional anatomical approaches to multidimensional molecular-level analysis.This marks a new phase in brain research method ology,characterized by higher resolution and systemic integration.Spatial transcriptomics technologies have significantly advanced the biological depth of neuroscience studies,offering novel paradigms for exploring dynamic neural circuit evolution and cellular diversity in the brain.By combining traditional anatomical localization,single-cell molecular connectomics,and functional imaging for macroscopic dynamic tracking,brain atlas research achieves"molecule-circuit-behavior"tri-level integration,thereby constructing molecular regulatory networks underlying dynamic neural circuit remodeling.However,current challenges persist in technical integration.Reference brain atlases hold great promise for elucidating brain homeostasis mechanisms,identifying abnormal circuit metabolic features in neurological disorders(e.g.,anxiety),and screening therapeutic targets.Future brain atlas research must advance multimodal technology fusion and cross-dimensional data integration to achieve precise mapping from static structures to dynamic functional networks,and thus provide revolutionary tools for neuroscience.

Objective:To investigate the application effect of propofol combined with remifentanil for anesthesia in children undergoing plasma adenoidectomy.Methods:Clinical data of 103 children who underwent plasma adenoidectomy in our hospital from Apr 2023 to Apr 2024 were retrospectively analyzed.Children were divided into two groups according to different anesthesia schemes.Children who received propofol+ketamine anesthesia were enrolled in the control group(n=52)and children who received propofol+remifentanil anesthesia were enrolled in the study group(n=51).Hemodynamic parameters were compared between the two groups at four time points:before anesthesia(T0),immediately after extubation(T1),5 minutes after extubation(T2),and 10 minutes after extubation(T3).The pain scores(CHIPPS)of the two groups were compared at 10,20,and 30 min after extubation.Post-anesthesia evaluation of discomfort(PAED)and incidence of restlessness during recovery in children were compared.The indicators of stress response(cortisol and epinephrine)were measured preoperatively and 1 day postoperatively.Total perioperative adverse events were analyzed.Results:The recovery times for spontaneous breathing,eye-opening,and extubation in the study group were shorter than those in the control group(P<0.05).The heart rate and mean arterial pressure level in the study group at T1-T3 were lower than those in the control group(P<0.05).The CHIPPS scores at 10,20,and 30 min after extubation and PAED scores during the recovery period in the study group were lower than those in the control group(P<0.05).The incidence of restlessness during the recovery period in the study group was lower than that in the control group(P<0.05).The levels of cortisol and epinephrine in the study group were lower than those in the control group on day 1 after surgery(P<0.05).There was no significant difference in the overall incidence of adverse reactions between the two groups(P>0.05).Conclusion:The use of propofol combined with remifentanil in plasma adenoidectomy can effectively shorten the recovery time of anesthesia in children,enhance analgesic effects,reduce blood circulation fluctuations and stress reactions,and reduce the incidence of restlessness,with reliable safety.

The CRISPR/Cas system has emerged as a promising platform for multiplex nucleic acid detection in recent years. Compared with traditional methods such as qPCR and NGS, CRISPR-based assays offer distinct advantages, including simplicity, high sensitivity, and low cost, making them particularly suitable for pathogen screening and early cancer diagnosis. To address the core challenges of CRISPR-based multiplex detection, three types of strategies have been developed: one-pot, spatial separation, and logic gate.These strategies enable simultaneous recognition of multiple targets and effective signal amplification. Applications span viral detection, antimicrobial resistance profiling, and tumor biomarker analysis. Despite persistent challenges such as signal cross interference and system complexity, the technology is evolving rapidly and holds strong potential for clinical translation.

Objective:To observe and analyze the pathogenic genes and clinical phenotype characteristics of retinitis pigmentosa sinepigmento(RPSP).Methods:A retrospective clinical study. Two patients (proband) and five family members from two RPSP families admitted to Xiamen Eye Center of Xiamen University in December 2022 and Shenzhen Eye Hospital in July 2023 were included in the study. Two families have no blood relationship and were both Han Chinese. Detailed ocular and systemic medical history and specialized examinations were performed for all members, including color fundus photography, fundus autofluorescence (FAF), and full field electroretinogram (ff-ERG) examination. The peripheral venous blood of all members was collected, and genomic DNA was extracted. Pathogenic genes and their loci were screened using whole exome high-throughput sequencing technology. Sanger sequencing was used to verify the pathogenic genes in the two pedigrees. The pathogenicity of candidate variants was evaluated according to the American Society for American College of Medical Genetics and Genomics (ACMG) classification criteria and guidelines for genetic variants.Results:The two probands were male, aged 9 and 7 years, respectively. The main complaint was poor binocular vision for 6 and 3 years and poor treatment effect of amblyopia. The proband (Ⅱ2) in family 1 had a pale red color on the optic disc, with leopard-like changes in the posterior pole and thinner retinal arteries. FAF showed mottled fluorescence attenuation outside the macular vascular arch. There was no significant waveform in both bright and dark visual responses of ff-ERG. He also had 6-toed deformity of both feet, renal cysts, and a slightly overweight body. The clinical diagnosis was non-pigmentary retinitis pigmentosa. The proband of family 2 (Ⅱ1) had poor binocular vision in a dark environment and had atrophy lesions on the nasal side of the optic disc and leopard print like changes in the fundus. FAF showed uneven enhancement in the fovea. ff-ERG showed severe abnormalities in dark and light response, with significant decrease and delay in b-wave amplitude and latency. He had no other systemic abnormalities. The clinical diagnosis was binocular RPSP. There were no abnormal ocular and systemic manifestations in the two family members. Gene sequencing revealed a homozygous mutation (c.534+1G>T) of BBS2 gene, which was inherited from the mother and father respectively. Based on clinical manifestations and genetic testing results, the final diagnosis was Bardet Biedl syndrome. The genetic sequencing results confirmed a novel compound heterozygous mutation (c.950T>G: p. Leu317Arg missense mutation and c.849+1G>C splicing mutation) of BBS7 gene. His father (Ⅰ1) and mother (Ⅰ2) carried M1 heterozygous variants. Combined with the clinical manifestations and genetic testing results, the final diagnosis was Bardet-Biedl syndrome (BBS). Family 2 proband (Ⅱ1) carried the BBS7 gene C.950T>G (p.Leu317Arg) (M2) missense variation and C.849 +1G>C (M3) splice site variation. His father (Ⅰ1) and mother (Ⅰ2) carried M3 shear site variation and M2 missense variation, respectively. The two families all fit the autosomal recessive inheritance pattern, and the genotype and clinical phenotype were coseparated. According to ACMG guidelines, M1, M2 and M3 were all identified as possible pathogenic variants. Conclusions:BBS2 gene M1 homozygous variation and BBS7 gene M2, M3 complex heterozygous variation are the possible pathogenic genes in family 1 and family 2, respectively. Two families are affected by BBS and RPSP, respectively.
