Electroencephalogram (EEG) is a non-invasive, high temporal-resolution technique for monitoring brain activity. However, affected by the volume conduction effect, EEG has a low spatial resolution and is difficult to locate brain neuronal activity precisely. The surface Laplacian (SL) technique obtains the Laplacian EEG (LEEG) by estimating the second-order spatial derivative of the scalp potential. LEEG can reflect the radial current activity under the scalp, with positive values indicating current flow from the brain to the scalp (“source”) and negative values indicating current flow from the scalp to the brain (“sink”). It attenuates signals from volume conduction, effectively improving the spatial resolution of EEG, and is expected to contribute to breakthroughs in neural engineering. This paper provides a systematic overview of the principles and development of SL technology. Currently, there are two implementation paths for SL technology: current source density algorithms (CSD) and concentric ring electrodes (CRE). CSD performs the Laplace transform of the EEG signals acquired by conventional disc electrodes to indirectly estimate the LEEG. It can be mainly classified into local methods, global methods, and realistic Laplacian methods. The global method is the most commonly used approach in CSD, which can achieve more accurate estimation compared with the local method, and it does not require additional imaging equipment compared with the realistic Laplacian method. CRE employs new concentric ring electrodes instead of the traditional disc electrodes, and measures the LEEG directly by differential acquisition of the multi-ring signals. Depending on the structure, it can be divided into bipolar CRE, quasi-bipolar CRE, tripolar CRE, and multi-pole CRE. The tripolar CRE is widely used due to its optimal detection performance. While ensuring the quality of signal acquisition, the complexity of its preamplifier is relatively acceptable. Here, this paper introduces the study of the SL technique in resting rhythms, visual-related potentials, movement-related potentials, and sensorimotor rhythms. These studies demonstrate that SL technology can improve signal quality and enhance signal characteristics, confirming its potential applications in neuroscientific research, disease diagnosis, visual pathway detection, and brain-computer interfaces. CSD is frequently utilized in applications such as neuroscientific research and disease detection, where high-precision estimation of LEEG is required. And CRE tends to be used in brain-computer interfaces, that have stringent requirements for real-time data processing. Finally, this paper summarizes the strengths and weaknesses of SL technology and envisages its future development. SL technology boasts advantages such as reference independence, high spatial resolution, high temporal resolution, enhanced source connectivity analysis, and noise suppression. However, it also has shortcomings that can be further improved. Theoretically, simulation experiments should be conducted to investigate the theoretical characteristics of SL technology. For CSD methods, the algorithm needs to be optimized to improve the precision of LEEG estimation, reduce dependence on the number of channels, and decrease computational complexity and time consumption. For CRE methods, the electrodes need to be designed with appropriate structures and sizes, and the low-noise, high common-mode rejection ratio preamplifier should be developed. We hope that this paper can promote the in-depth research and wide application of SL technology.

Abstract The association of childhood sleep disorders and common oral diseases are increasingly recognized as public health challenges. The paper reviews epidemiological evidence on the bidirectional associations between multidimensional sleep indicators-including insufficient sleep duration,sleep related disorders (sleep apnea and bruxism) and evening chronotype and common oral diseases such as dental caries, periodontal diseases, and craniofacial developmental anomalies. It also explores potential neurobiological mechanisms underlying these associations. The review proposes that future research should employ longitudinal cohort studies and multi omics technologies to further validate prospective causal relationships, thereby providing a theoretical foundation for developing childhood health interventions.

Ulcerative colitis （UC） is a refractory disease of the digestive system characterized by diverse etiologies， complex pathogenesis， a prolonged course， and frequent relapses. In recent years， the incidence of UC has been increasing annually， severely impairing patients' quality of life， posing a risk of malignant transformation that may threaten patients' lives， and resulting in a substantial medical burden. Traditional Chinese medicine （TCM） compound formulas， with their advantages of multi-component and multi-target actions， have become a new therapeutic option for UC. The NOD-like receptor pyrin domain-containing 3 （NLRP3） inflammasome is a core component of innate immunity， and its aberrant activation is closely associated with the onset and progression of UC， involving multiple processes such as inflammation and oxidative stress， and exhibiting crosstalk with pathways including nuclear factor-κB （NF-κB）， nuclear factor erythroid 2-related factor 2 （Nrf2）， and thioredoxin-interacting protein （TXNIP）. At present， NLRP3 has become one of the most intensely studied hotspots in UC-related research. Although increasing studies have focused on the regulation of the NLRP3 inflammasome by TCM compound formulas for UC treatment， challenges remain due to the complex pathogenesis of UC and the compositional diversity of TCM， hindering the realization of precision therapy. In this context， by reviewing literature from the past decade， this paper summarizes the activation process of NLRP3 and its relationship with UC， and elucidates the roles and mechanisms by which TCM compound formulas regulate the NLRP3 inflammasome and related signaling pathways， with a view to providing a reference for further research into the pathogenesis of UC， TCM treatment strategies， and their mechanisms of action.

Aim To examine the neuroprotective im-pacts of total saponins from Trillium tschonoskii maxim(TST)on cerebral ischemia-reperfusion injury(CIRI)in rats and delve into the mechanisms of ferroptosis.Methods The CIRI model was prepared by dividing male SD rats into the model group,TST(0.1 g·kg-1)group,Donepezil hydrochloride(0.45 mg·kg-1)group,and sham group.The cognitive functions of rats in each group were assessed through the Morris water maze test,the changes in neurological function were evaluated using the Zea-Longa method,the infarct area was observed via TTC staining,and the pathologi-cal alterations in brain tissue were analysed using HE and Nissl staining.To further investigate the underly-ing mechanism,the mitochondrial structural changes were examined using transmission electron microscopy,and the levels of GSH-PX,MDA,and SOD were ana-lyzed.Additionally,the expressions of GPX4 and Nrf2 proteins were evaluated through immunohistochemistry and immunofluorescence.Furthermore,the protein lev-els of Keap1/Nrf2/HO-1 and Nrf2/SLC7A11/GPX4 pathways in rats were examined using Western blot-ting.Results The rats in the model group displayed diminished learning and memory capabilities in com-parison to those in the sham group,as well as a signifi-cantly increased cerebral infarction area and higher neurological function scores(P＜0.01),significantly increased cerebral infarct area,disordered and loosely arranged neurons,and reduced Nissl bodies.Addition-ally,mitochondria showed typical signs of ferroptosis.Changes related to ferroptosis included decreased activ-ities of SOD and GSH-PX(P＜0.01)and increased MDA levels(P＜0.01).The expression of GPX4 and Nrf2-positive cells was significantly reduced,along with decreased fluorescence intensity of GPX4.Further-more,the protein expression of Keap1,Nrf2,HO-1,GPX4,SLC7A11 in the hippocampus decreased(P＜0.05,P＜0.01).Following the administration of TST,these effects showed improvement.Conclusions TST has neuroprotective effects,enhancing learning and memory abilities while reducing oxidative stress levels.The mechanism may involve the inhibition of ferroptosis through the Keap-1/Nrf2/HO-1 and Nrf2/SLC7 A11/GPX4 pathways.

Aim To investigate the mechanism of py-roptosis mediated by the NLRP3/caspase-1/GSDMD signaling pathway and the intervention effect of Radix Angelica Sinensis and Radix Astragalus ultrafiltration extract(RAS-RA)in radiation-induced pulmonary fi-brosis.Methods Fifty Wistar rats were randomly di-vided into five groups,with ten rats in each group.Ex-cept for the blank control group,all other groups of rats were anesthetized and received a single dose of 40 Gy X-ray local chest radiation to establish a radiation-in-duced pulmonary fibrosis rat model.After radiation,the rats in the RAS-RA intervention groups were orally administered doses of 0.12,0.24 and 0.48 g·kg-1 once a day for 30 days.The average weight and lung index of the rats were observed after 30 days of contin-uous administration.Hydroxyproline(HYP)content in lung tissue was determined by hydrolysis method.The levels of IL-18 and IL-1 β in serum were detected by ELISA.Lung tissue pathological changes were ob-served by HE and Masson staining.Ultrastructural changes in lung tissue were observed by transmission e-lectron microscopy.The expression levels of NLRP3/caspase-1/GSDMD pyroptosis pathway-related proteins and fibrosis-related proteins in lung tissue were detec-ted by Western blot.Results Compared with the blank group,the HYP content in lung tissue and the levels of IL-18 and IL-1 β in serum significantly in-creased in the model group(P＜0.01).HE and Mas-son staining showed inflammatory cell infiltration and collagen fiber deposition.Transmission electron mi-croscopy revealed increased damaged mitochondria,disordered arrangement,irregular morphology,shallow matrix,outer membrane rupture,mostly fractured and shortened cristae,mild expansion,increased electron density of individual mitochondrial matrix,mild sparse structure of lamellar bodies,partial disorder,unclear organelles,and characteristic changes of pyroptosis.Western blot analysis showed increased expression of caspase-1,GSDMD,NLRP3,CoL-Ⅰ,α-SMA,and CoL-Ⅲ proteins(P＜0.01).Compared with the model group,the RAS-RA intervention group showed signifi-cant improvement in body mass index and lung index of rats,decreased levels of IL-18 and IL-1 β inflammatory factors(P＜0.01),improved mitochondrial structure,reduced degree of fibrosis,and decreased expression of caspase-1,GSDMD,NLRP3,COL-Ⅰ,COL-Ⅲ,and α-SMA proteins in lung tissue(P＜0.01).Conclusion RAS-RA has an inhibitory effect on radiation-in-duced pulmonary fibrosis,and its mechanism may be related to the inhibition of pyroptosis through the regu-lation of the NLRP3/caspase-1/GSDMD signaling pathway.

The distribution of Ixodes and Ana plasma carried by Ixodes ticks in Anhui Province was clarified as reference for prevention and control of anaplasmosis.In total,630 hard ticks were collected from Jinzhai County,Hanshan County,Jing-de County and Chaohu City in Anhui Province from April to August 2023.Ticks were identified by morphological analysis and 16S rRNA sequencing.Nested PCR with Anaplasma species-specific primers were used to detect 16S rRNA of Anaplasma spe-cies carried by ticks.A phylogenetic tree was constructed using MEGA11.0 software.Of the identified ticks,18.8％(18/96)were Rhipicephalus microplus and 81.2％(78/96)were Haemaphysalis longicorni in Jinzhai County of Anhui Province,all were H.longicorni in Hanshan County and Chaohu City,while the main species in Jingde County was R.microplus.The posi-tive rate of Anaplasma carried by H.longicornis was 30.9％(102/330),which included A.bovis at 1.8％(6/330),A.phagocytophilum at 21.8％(72/330)and uncultured Anaplasma species at 7.3％(24/330).R.microplus was positively cor-related to A.bovis(13.6％,18/132).The uncultured Anaplasma species was mainly detected in host-free ticks.A.phagocy-tophilum was detected in 24.4％of parasitic ticks and 15.8％of host-free ticks.The positive rates of host-free and parasitic ticks were 19.9％and 17.8％,respectively.These results show that H.longicornis and R.microplus were the dominant ticks in several counties of Anhui Province.H.longicornis and R.microplus as well as free and parasitic ticks all carried Anaplas-ma.

Objective:To investigate the incidence of PTPN11 gene mutation and its associated gene mutations in adult patients with acute myeloid leukemia(AML),and analyze its clinical characteristics.Methods:Second-generation sequencing and Sanger sequencing were used to detect 51 gene mutations,and multiplex-PCR was used to detect 41 fusion genes from 451 newly diagnosed adult AML patients admitted to Affiliated Hospital of Jiangnan University,Changzhou Second People's Hospital,Wuxi People's Hospital and Wuxi Second People's Hospital from January 2017 to July 2022.Results:Among 451 primary adult AML patients,the PTPN11 gene mutation was detected in 34 cases,and the mutation rate was 7.5％.In the 34 patients,37 PTPN11 alterations were found,which were exclusively missense mutations affecting residues located within the N-SH2(31 cases)and PTP(6 cases)domains and clustered overwhelmingly in exon 3.The platelet count of PTPN11 mutation patients was 76.5(23.5,119.0)× 109/L,which was significantly higher than 41.0(22.0,82.5)×109/L of wild-type patients(P＜0.05).While,there were no significant differences in sex,age,peripheral white blood cell count,hemoglobin,and bone marrow blast between PTPN11 mutation and wild-type patients(P＞0.05).In FAB subtypes,PTPN11 mutations were mainly distributed in M5,followed by M2 and M4,less frequently in M3 and M6.There was no significant difference in the distribution of FAB subtypes between PTPN11 mutation and wild-type patients(P＞0.05).A total of 118 AML patients were detected positive fusion gene,among which patients with PTPN11 mutations had a higher incidence of positive MLL-AF6 than wild-type ones(P＜0.01).97.1％of 34 patients with PTPN11 mutations were accompanied by other mutations,in descending order,they were respectively NPM1(38.2％),NRAS(32.4％),FLT3-ITD(32.4％),DNMT3A(32.4％)and KRAS(23.5％),etc.Conclusion:PTPN11 mutation has a certain incidence in AML patients and is clustered overwhelmingly in exon 3.ALL of them are exclusively missense mutations,and most often present in conjunction with NPM1 mutations.FAB typing of PTPN11 mutation is mostly manifested as M5 subtype,which is associated with higher platelet counts.

Objective:To analyze the type and distribution characteristics of irregular antibodies in 71847 hospitalized patients who prepared to accept blood transfusion,and to explore their role in safe blood transfusion. Methods:71847 patients who applied for red blood transfusion from January 2020 to October 2023 were selected.All specimens were screened and identified for the irregular antibody by microcolumn gel antiglobulin technique.Results:Among the 71847 patients preparing for accept blood transfusion,301 cases tested positive for irregular antibodies (0.42％).Of these 301 antibody-positive patients,252 (83.72％)exhibited alloantibodies.The Rh blood group system was the most common,accounting for 179 cases (59.47％).Antibodies in Rh blood group system included anti-E (135,44.85％),anti-E+c (24,7.97％),anti-C+e (10,3.32％),anti-c (6,1.99％),anti-D (3,1.00％),and anti-D+C (1,0.33％).By analyzing 301 cases with irregular antibodies,it found the positive rate of>60 years old group was higher than that in≤60 years old (0.61％vs 0.33％),female group was higher than that in male group (0.50％ vs 0.31％),internal medicine and gynaecology and obstetrics groups were both higher than that in surgery group (1.25％ vs 0.20％;0.32％ vs 0.20％),group with pregnancy/transfusion history was higher than that in non-pregnancy/transfusion history (0.64％ vs 0.13％),the differences were statistically significant (P<0.05). Conclusion:In the routine monitoring of the blood group,it is necessary to detect RhE,so as to reduce the positive rate of irregular antibodies greatly and further ensure the safety of blood transfusion.

Objective:To compare single-cell transcriptome sequencing data from skin samples of patients with atopic dermatitis (AD) and those from skin samples of healthy controls, and to investigate immunometabolic characteristics of inflammatory dendritic epidermal cells (IDECs) in skin lesions of patients with AD.Methods:An in-depth analysis was carried out on previously published single-cell sequencing data from 8 AD patients and 7 healthy controls in the Gene Expression Omnibus database (GSE 153760). Marker genes were used to screen out IDECs, and differentially expressed genes in IDECs between the two groups were analyzed. Kyoto Encyclopedia of Genes and Genomes enrichment analysis was performed on these differentially expressed genes, the "AddModuleScore" function in the Seurat package was used to evaluate the IDEC-involved inflammatory and metabolic pathways in the two groups, and Mann-Whitney rank sum test was used for statistical analysis; correlations between the IDEC-involved metabolic and inflammatory pathways were evaluated using the above scores and the "cor" and "cor.test" functions in R packages.Results:A large number of IDECs infiltrating the skin lesions of AD patients highly expressed Th2 chemokines (CCL17), antigen presentation-related genes (CD1B), endothelial growth-related genes (TYMP, AREG), inflammation-related genes (S100A8, S100A10, LGALS1), stromal fibrosis-related genes (MMP12, ADAM19), metabolism-related genes (LDHA, LIPA, GLUL), and danger signaling-related genes (HSPA1B, HSP90AA1, HSPB1, HSPH1). The activities of glucose energy metabolism, glycolytic metabolism, nucleotide metabolism, glutamate and glutamine metabolism, and amino acid metabolism were significantly upregulated in IDECs in AD patients, and were positively correlated with Th2 inflammation levels; the activities of oxidative phosphorylation and lipid metabolism were significantly downregulated in IDECs in AD patients, and the lipid metabolism level was negatively correlated with Th2 inflammation levels. Glutamine metabolism and glucose energy metabolism activities were positively correlated with Th22 inflammation levels; Th1 and Th17 inflammation levels were negatively correlated with the activities of pentose phosphate metabolism, nucleotide metabolism, glycolytic metabolism, and amino acid metabolism pathways.Conclusion:The inflammation- and metabolism-related genes were abnormally expressed in IDECs in skin lesions of AD patients, and activities of multiple metabolic pathways were markedly upregulated in IDECs, among which the glycolysis metabolism activity was mostly correlated with Th2 inflammation levels.
