OBJECTIVE: To analyze the rules of moxibustion for low back pain by ZHOU Meisheng by using data mining and knowledge graph technology. METHODS: Taking the medical cases of moxibustion for low back pain from ZHOU Meisheng's legacy manuscripts and existing works as the research objects, information on disease types, symptoms, tongue manifestations, pulse conditions, syndrome patterns, moxibustion methods and acupoints were collected. Frequency statistics and community analysis were conducted by the ancient and modern medical record cloud platform V 2.3.7, cluster analysis of high-frequency acupoints was performed by SPSS26.0, association rule analysis of high-frequency acupoints was performed by SPSS Modeler 18.0, and the generated linked data were imported into Cytoscape 3.9.1 for complex network analysis. Knowledge graph of moxibustion for low back pain by ZHOU Meisheng was constructed based on the results of data mining. The data storage and display of knowledge graph were realized through the Neo4j 3.5.25 graph database, and the Cypher query language was used for knowledge graph retrieval and discovery. RESULTS: A total of 219 medical cases were collected, involving 14 disease types, 85 related clinical symptoms, 5 related TCM syndrome types, and 6 moxibustion methods. The acupoints were mostly attributed to the governor vessel, the bladder meridian of foot-taiyang, non-meridian and non-acupoint areas. The core prescription of acupoints derived from complex network analysis included tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34), which were largely coincides with high-frequency acupoints. Cluster analysis obtained 4 cluster combinations. Community analysis yielded 6 communities, each corresponding to different acupoints.The constructed knowledge graph contained 187 nodes and 696 relationships, by retrieving clinical elements related to low back pain, the disease-moxibustion association graph, disease-acupoint association graph, accompanying symptom-acupoint association graph and syndrome type-matching point association graph were obtained. CONCLUSION When treating low back pain with moxibustion, ZHOU Meisheng adopts the principle of promoting circulation, distinguishing diseases to determine the treatment, selecting acupoints according to the diseases, and matching points according to the symptoms.And taking tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34) as core acupoints, combined with tenderness point selection, acupoint selection based on meridian and zangfu syndrome differentiation, "sunshine area" acupoint selection, yin-yang acupoint matching. Additionally, he skillfully employs special points, such as Zhongzhu (KI15) and ear tips, pays attention to the reform of moxibustion tools, and innovates the moxibustion techniques, using distinctive moxibustion tools and methods to treat low back pain.

POEMS syndrome is a rare condition associated with plasma cell disorders， and it often involves multiple systems and has diverse clinical manifestations. This article reports two cases of POEMS syndrome with hepatosplenomegaly as the initial manifestation. During the course of the disease， the patients presented with lower limb weakness， hepatosplenomegaly， lymph node enlargement， ascites， hypothyroidism， positive M protein， and skin hyperpigmentation， and ¹⁸F-FDG PET-CT imaging revealed bone lesions mainly characterized by osteolytic changes and plasma cell tumors. There was an increase in the serum level of vascular endothelial growth factor. The patients were finally diagnosed with POEMS syndrome， and the symptoms were relieved after immunomodulatory treatment.

Objective:To summarize the genotype and clinical phenotype characteristics of children with epilepsy associated with the SCN1B gene encoding the sodium channel β1 subunit. Methods:The genotypes and clinical phenotypes of patients with SCN1B variants among suspected genetic epilepsy cases treated at the Children′s Medical Center of Peking University First Hospital between May 2016 and July 2024 were analyzed. These variants were identified using next-generation sequencing and subsequently validated by Sanger sequencing or quantitative polymerase chain reaction methods. Results:A total of 17 patients were analyzed, including 8 males and 9 females. Ten cases of missense variations (including 2 with the same variations), 4 cases of deletion variations, and 1 case each of nonsense variations, splice site variations, and exons 4-5 deletions were identified. Among them, 6 cases had novel SCN1B variations. The variants in 11 cases were inherited from 1 parent. Eleven types of gene variants have not been reported yet. Onset of epilepsy ranged from 3 months to 5 years and 3 months old (median age: 14 months). Types of seizures included generalized tonic-clonic seizures (GTCS) in 14 cases, focal seizures in 9 cases, myoclonic seizures in 3 cases, atypical absence seizures in 2 cases and epilepsy spasms, tonic seizures and atonic seizures in 1 case each. Eleven cases had diverse seizure types. Fourteen cases (14/17) demonstrated fever sensitivity. Electroencephalography revealed focal discharges in 3 cases, coinciding with focal and generalized discharges in 3 additional cases, and multifocal discharges in 6 cases. Seizures were identified in 4 cases: 1 case of myoclonic seizures, 1 case of GTCS, 1 case of atypical absence seizures, and 1 case exhibiting both myoclonic and tonic seizures. Nine cases (9/17) were diagnosed with genetic epilepsy with febrile seizures plus, 1 case diagnosed with myoclonic epilepsy in infancy and 1 diagnosed with infant epileptic spasms syndrome. There were 2 cases of nonspecific developmental epileptic encephalopathy, while the remaining 4 cases could not be diagnosed with a specific epileptic syndrome. Effective antiseizure medications (ASMs) included valproate in 8 cases, levetiracetam in 5 cases, topiramate in 3 cases, clobazam in 2 cases, clonazepam and vigabatrin in 1 case each. Sodium channel blockers exacerbated seizures in 3 cases, specifically oxcarbazepine in 2 cases and lamotrigine in 1 case. At the last follow-up, seizures were controlled for at least 6 months in 14 patients (14/17), while seizures remained uncontrolled in 3 patients despite trialing 2 or more ASMs. Thirteen patients exhibited normal development, while 4 experienced developmental delays. Conclusions:The heterozygous variants in children with SCN1B gene-related epilepsy include missense, deletion, nonsense, splice site variants, and exon deletions. The correlation between different genetic variants and clinical phenotypes remains unclear. These variants are associated with epilepsy onset from infancy to early childhood, presenting with various seizure types, with GTCS being the most common. Phenotypic manifestations can vary significantly in severity, ranging from benign febrile seizures or febrile seizures plus to developmental epileptic encephalopathy. Valproic acid demonstrates the highest effectiveness rate, while the use of sodium channel blockers may worsen seizures in certain patients, necessitating cautious administration.

Objective:To summarize the clinical phenotype and genetic features of patients with relapsing encephalopathy with cerebellar ataxia (RECA) caused by ATP1A3 gene R756 variants. Methods:A retrospective analysis was performed on patients carrying the ATP1A3 gene R756 variants, identified by whole-exome sequencing of family members, at Capital Center for Children′s Health, Capital Medical University and Children's Medical Center, Peking University First Hospital from August 2005 to February 2024. Their clinical, laboratory, neuroimaging, electrophysiological and genetic characteristics were summarized. Results:A total of 13 RECA patients were enrolled in this study, including 8 males and 5 females. The age of onset was 8 months to 5 years, with a median age of onset of 18 months. All of 13 patients presented paroxysmal episodes of neurological decompensations triggered by fever and residual symptoms following the acute phase. During acute attack stage, ataxia was observed in all 13 cases, muscle weakness in 12 cases, dysarthria in 12 cases, altered consciousness in 10 cases, dysphagia in 10 cases, dystonic episodes in 4 cases, abnormal eye movement in 2 cases, choreoathetosis in 2 cases, and epileptic seizures in 1 case. All 13 patients had residual symptoms during the nonparoxysmal period, of whom 9 patients had ataxia, 9 patients had dysarthria, 4 patients had dystonia, 3 patients had cognitive disorders, and 1 patient had epileptic seizures. All 13 cases had ATP1A3 missense variants, and variant c.2266C>T/p.R756C was found in 6 cases, c.2267G>A/p.R756H in 5 cases, and c.2267G>T/p.R756L in 2 cases. Nine cases carried de novo variants, 4 with inherited variants. Conclusions:RECA caused by variants of ATP1A3 in residue 756 typically presents with an acute onset during infancy or early childhood, precipitated by febrile episodes and characterized by recurrent episodes of ataxia, with bulbar paralysis, muscle weakness and altered consciousness. Recurrence is common, and the most common persistent symptoms are cerebellar ataxia and dysarthria. A few patients have cognitive impairment. Three types of ATP1A3 gene variants R756C, R756H and R756L are related with RECA, and R756C is the most common variant.

Objective:To analyze the clinical features and diagnostic process of ring chromosome syndrome.Methods:Clinical data of 9 children with ring chromosome syndrome who were treated at the Children′s Medical Center of Peking University First Hospital from September 2009 to May 2025, were summarized and analyzed in a case series study. The data included clinical manifestations, types of epileptic seizures, genetic testing, treatment outcomes, and follow-up results, et al.Results:Among the 9 children with ring chromosome syndrome, there were 6 girls and 3 boys, including 4 children with ring chromosome 20 syndrome, 3 children with ring chromosome 14 syndrome, and 1 child each with ring chromosome 13 and 17 syndrome. All 9 children had de novo chromosomal variations. Among them, 3 children of ring chromosome 20 syndrome were mosaic, and the remaining 6 children were non-mosaic. All 9 children exhibited diverse clinical features, especially those with ring chromosome 20 syndrome, which presented with specific manifestations. The 4 children with ring chromosome 20 syndrome all had acute epileptic seizures as the initial symptom, with onset ages of 67, 39, 17, and 96 months, and all had focal seizures. One child with ring chromosome 20 syndrome had non-convulsive status epilepticus. Development of all 4 children with ring chromosome 20 syndrome was normal before seizure onset, but 3 children showed regression after onset. No physical deformities were observed in 4 children with ring chromosome 20 syndrome, and 2 children were misdiagnosed, 3 children underwent whole exome sequencing and copy number variation analysis in their families, with no abnormalities detected. All 4 children with ring chromosome 20 syndrome were diagnosed through chromosomal karyotype analysis, the intervals between onset and diagnosis were 2, 81, 19 and 13 months, respectively. Follow-up showed that epileptic seizures were not controlled in all 4 children with ring chromosome 20 syndrome. The other 5 children were characterized by developmental delay as the initial symptom, followed by epileptic seizures between 3 and 24 months of age. Developmental regression of the other 5 children did not occur after onset, 2 of them had microcephaly, and 3 had wide-set eyes. No misdiagnoses were reported in these 5 children, and the intervals between onset and diagnosis were 7, 3, 55, 3, and 106 months, respectively. Follow-up showed that epileptic seizures were controlled in these 5 children. Conclusions:Ring chromosome 20 syndrome typically manifest with epilepsy as the initial symptom and are refractory to drug treatment, their early development is entirely normal. Ring chromosome 13, 14, and 17 syndrome are characterized by developmental delay from an early age, followed by the onset of epileptic seizures, which are easily controlled. Conventional whole exome sequencing and copy number variation analysis in families rarely detect ring chromosome abnormalities. Early chromosomal karyotype analysis is essential for the diagnosis of ring chromosome syndrome.

Objective:To summarize the clinical phenotypes and genetic variations of children with epilepsy related to CLCN4 gene mutations. Methods:A retrospective analysis was conducted on 9 children with epilepsy who were diagnosed with CLCN4 gene mutations through whole-exome sequencing of family members. These children were treated at the Department of Pediatrics, Peking University First Hospital from December 2016 to March 2024. Their clinical manifestations, electroencephalogram, cranial imaging characteristics, and treatment follow-up were reviewed. Results:Among the 9 children, 6 were male and 3 were female. All cases involved de novo mutations. Three cases carried the c.823G>A/p.V275M variant, 2 cases carried the c.2152C>T/ p.R718W variant, 1 case carried the c.1630G>A/pG544R variant, and 1 case carried the c.2167C>T/ p.R723W variant. Two cases carried the unreported new variant c.848G>T/p.S283I and c.818G>A/ p.G273E. The onset age of epilepsy ranged from 55 days to 10 years, with a median onset age of 14 months. Seven out of 9 children had epilepsy onset before the age of 2 years. The types of seizures varied: 8 had focal seizures, 1 had generalized tonic-clonic seizures, 2 had myoclonic seizures, 1 had epileptic spasms, and 1 had atypical absence seizures. Three children experienced multiple types of seizures. All 9 children exhibited developmental delays to varying degrees: 8 had global developmental delay and 1 had cognitive developmental delay. Developmental delays were observed in 7 children before the onset of epilepsy. Clinically, 1 child was diagnosed with infantile epileptic spasms syndrome, 7 with unclassified developmental and epileptic encephalopathy, and 1 with focal epilepsy with developmental delay. At the last follow-up, the age of the children ranged from 2 years and 5 months to 13 years and 9 months. Seizures had been controlled in 3 children for a duration of 4 to 12 months. Conclusions:De novo variants are common in CLCN4 variants. Most seizures onset in infancy, seizure types are various, and focal seizures are common. Most of them have developmental delay and drug-resistant epilepsy, and some of them have developmental delay before seizure onset, which is consistent with the characteristics of developmental and epileptic encephalopathy.

Objective To study the brain functional connectivity(FC)changes in patients with normal tension glau-coma(NTG)and healthy volunteers using FC technique of resting-state functional magnetic resonance imaging(rs-fMRI)based on V1 region seed point(ROI),so as to explore the pathogenesis and early diagnosis of NTG.Methods Fourteen NTG patients(NTG group)who met the inclusion criteria and 14 healthy controls(HCs group)were enrolled.The clinical data of all subjects were collected,and rs-fMRI was performed in both groups.The magnetic resonance data was pre-pro-cessed by software,and bilateral A1 regions were taken as the ROI to analyze their correction with the whole brain voxel time series and obtain the FC value between the ROI and the whole brain by comparison of FC values in resting state be-tween the groups.Pearson correlation analysis was used to explore the relationship between FC value in the brain regions with significant differences with the ROI and clinical variables in the NTG group.Results Compared with the subjects in the HCs group,there were no statistically significant differences in age,gender,body weight,cup-disc ratio and 24 h mean intraocular pressure of patients in the NTG group(all P＞0.05),and there were statistically significant differences in the best corrected visual acuity(BCVA)of both eyes and peripapillary retinal nerve fiber layer thickness(RNFLT)(all P＜0.05).The Pearson correlation analysis showed that FC value of the brain regions with abnormal FC to V1 region were cor-related with RNFLT in the NTG group(P＜0.05).ROI1-left superior frontal gyrus,ROI1-right superior frontal gyrus,ROI2-left cingulate gyrus and ROI2-right middle frontal gyrus were significantly positively correlated with RNFLT(all P＜0.05).Compared with the HCs group,the brain regions with reduced FC to the right ROI in the NTG group were the left superior frontal gyrus and right superior frontal gyrus;the brain regions with reduced FC to the left ROI were the left cingulate gyrus and right middle frontal gyrus.Conclusion Compared to healthy individuals,NTG patients have significant changes in the functional connections between certain specific brain regions and V1 region,including bilateral superior frontal gyrus,left cingulate gyrus,and middle frontal gyrus.The changes in brain functional activity may be caused by visual dysfunction caused by NTG,leading to functional impairment of the visual and cognitive emotion processing brain regions,which may be one of the potential neuropathological mechanisms in NTG patients.
