Abstract
Objective: To explore the clinical and imaging features of acute encephalopathy with biphasic seizures and late reduced diffusion(AESD) in children. Methods: For the case series study, 21 children with AESD from Peking University First Hospital, Provincial Children's Hospital Affiliated to Anhui Medical University, Children's Hospital of Fudan University, and Shanxi Children's Hospital who were diagnosed and treated from October 2021 to July 2023 were selected. Clinical data were collected to summarize their clinical information, imaging, and laboratory tests, as well as treatment and prognostic characteristics. Descriptive statistical analysis was applicated. Results: Of the 21 cases with AESD, 11 were males and 10 were females, with the age of onset of 2 years and 6 months (1 year and 7 months, 3 years and 6 months). Of the 21 cases, 18 were typical cases with biphasic seizures. All typical cases had early seizures within 24 hours before or after fever onset. Among them, 16 cases had generalized seizures, 2 cases had focal seizures, and 7 cases reached the status epilepticus. Of the 21 cases, 3 atypical cases had late seizures in biphasic only. The late seizures in the 21 cases occurred on days 3 to 9. The types of late seizures included focal seizures in 12 cases, generalized seizures in 6 cases, and both focal and generalized seizures in 3 cases. Diffusion-weighted imaging (DWI) test on days 3 to 11 showed reduced diffusion of subcortical white matter which was named "bright tree sign" in all cases. The diffuse cerebral atrophy predominantly presented in the front-parietal-temporal lobes was found in 19 cases between day 12 and 3 months after the onset of the disease. Among 21 cases, 20 had been misdiagnosed as autoimmune encephalitis, central nervous system infection, febrile convulsions, posterior reversible encephalopathy syndrome, acute disseminated encephalomyelitis, and hemiconvulsion-hemiplegia-epilepsy syndrome. All the cases received high-dose gammaglobulin and methylprednisolone pulse therapy with poor therapeutic effect. By July 2023, 18 cases were under follow-up. Among them, 17 cases were left with varying degrees of neurologic sequelae, including 11 cases with post-encephalopathic epilepsy; 1 recovered completely. Conclusions: AESD is characterized by biphasic seizures clinically and "bright tree sign" on DWI images. Symptomatic and supportive treatments are recommended. The immunotherapy is ineffective. The prognosis of AESD is poor, with a high incidence of neurological sequelae and a low mortality.

Abstract
Objective: To investigate the clinical features, pathological phenotype, treatment and prognosis of Castleman's disease in children. Methods: Clinical data of 15 children diagnosed with Castleman's disease in Henan Provincial People's Hospital and the First Affiliated Hospital of Zhengzhou University from May 2010 to October 2019 were analyzed retrospectively. The clinical characteristics, laboratory examination and histopathological data were analyzed. Results: Among the 15 Castleman's disease patients, 12 were males and 3 females. The age of first visit was 12 (10, 15) years. The time from mass discovery to pathologic diagnosis was 9.0 (2.0, 13.0) months. The majority of patients were unicentric (13 cases), and the histopathological type was hyaline vascular (11 cases). Unicentric lesions were most common in the neck (11 cases), all 13 patients received complete surgical resection of the lesions, the follow-up time was 20.0 (13.5, 50.5) months, and the prognosis was good. Two cases were multicentric type, the pathological types were mixed variant, meeting the criteria of idiopathic Castleman's disease, the two children underwent partial surgical resection, one was treated with rituximab and prednisone and the other was treated with thalidomide and prednisone. The follow-up time was 32 months and 10 month, both of them had good prognosis. Conclusions: Most cases of Castleman's disease in children are diagnosed late, and the unicentric type is dominant. The most common pathological type is hyaline vascular, which is characterized by painless lymphadenopathy, while multicentric type has systemic symptoms and both of them have a good overall prognosis.

Abstract
Objective: To summarize the clinical characteristics of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and compare the differences in efficacy of different disease-modifying drugs. Methods: An ambispective cohort study was conducted in 42 children diagnosed with MOGAD at Department of Pediatrics, Peking University First Hospital from January 2012 to March 2021 and conducted long-term follow-up to analyze clinical phenotypes and compare the efficacy of different disease-modifying drugs such as rituximab, mycophenolate mofetil and azathioprine. Kruskal-Wallis H test was used to compare the annual relapse rate of disease-modifying drugs at different times, expanded disability status scale (EDSS) score at the last follow-up, and Wilcoxon rank test was used to compare the annual relapse rate before and after modified disease therapy. The Log-rank (Mantel-Cox) survival curve was used to compare the relapse rate of different disease-modifying drugs. Results: Of the 42 cases, 22 were male and 20 were female, with the age at disease onset of 5.96 (2.33-12.90) years. The disease duration was 4.46 (1.25-13.00) years at the last follow-up with 161 clinical acute attacks. Acute disseminated encephalomyelitis (ADEM) was the most common phenotype of first attack and all attacks during disease course ((60% (25/42) for first attack, 38% (61/161) for all attacks). The most common clinical syndrome was neuromyelitis optica spectrum disorders (NMOSD) (50%, 21/42). Of the 42 children, 5 (12%) showed encephalitis and 6 (14%) combined with anti-N-methyl-D-aspartate receptor (NMDAR) antibody overlap syndrome. The most commonly involved areas of brain magnetic resonance imaging (MRI) were subcortical white matter (71%, 88/124), cortex (26%, 32/124) and periventricular white matter (25%, 32/124). Spinal cord MRI was most frequently involved in cervical (70%, 16/23) and thoracic (61%, 14/23) medulla, and 43% (10/23) longitudinally extensive transeverse myelitis. Disease-modifying drugs were used in 34 patients. The annual relapse rate after treatment with rituximab, mycophenolate mofetil and azathioprine decreased (all P<0.05) and there was no statistically significant difference in the annual relapse proportion among the groups (P=0.307). Conclusions: The most common clinical attack of first and all of MOGAD in children is ADEM, and the most common clinical syndrome is NMOSD. Rituximab, mycophenolate mofetil and azathioprine can reduce the annual relapse rate, but it is not clear effect of which treatment is better.

Abstract
Objective: To analyze the incidence characteristics of occupational chronic benzene poisoning under two diagnostic criteria. Methods: In March 2020, 126 patients who were divided into the old criteria group (74 cases) and the new criteria group (52 cases) were retrospectively analyzed. These patients were diagnosed with occupational chronic benzene poisoning, and were diagnosed in our hospital during the period of January 2009 to December 2019. The gender composition, age of onset, years of benzene exposure, industry distribution, work type, benzene concentration in working environment and diagnostic grade of the two groups of patients were analyzed and compared. The follow-up of 22 benzene poisoning observation subjects under the old criteria were retrospectively analyzed. Results: There were no statistically significant differences in gender composition, age of onset, years of benzene exposure, industry distribution and work type between the old criteria group and the new criteria group (P>0.05) . In the old criteria group and the new criteria group, 41.9% (31/74) and 17.3% (9/52) of the patients' workplace benzene concentration exceeded the maximum allowable concentration, respectively. The composition of different benzene concentration in the workplace between the two groups showed statistically significant (P<0.05) . In the old criteria group, the proportion of mild poisoning (79.7%, 59/74) was the majority, while in the new criteria group, the proportion of moderate and severe poisoning (51.9%, 27/52) were the majority, and there was statistically significance in the composition ratio of diagnostic grade between the two groups (P<0.05) . Under the old criteria, after folow-up of 22 cases of benzene poisoning observation subjects, we observed that 8 cases (36.4%) progressed to the level of chronic benzene poisoning. Conclusion: The revision of diagnostic criteria for benzene poisoning may affect the composition of diagnosis classification. Based on the rights and interests of workers, formulating more complete diagnostic criteria and system policies will be more conducive to the development of occupational benzene poisoning prevention and control.

Abstract
Aims
The possibility of endovascular reconstruction of aortic valve, sinus of Valsalva, and ascending aorta by a minimal-invasive single endograft has not been proven in vivo. Combining our own long-term experiences from transcatheter aortic valve replacement (TAVR) and Thoracic Endovascular Repair (TEVAR) for ascending and arch dissection, we designed the special endo-graft: a novel one-piece valved-fenestrated-bifurcated endografting, and tried to endovascularly reconstruct the area from Left ventricular outflow tract to aortic arch in animal experiments.
Methods and results
For 20 healthy adult female pigs weighed between 62.3±2.2 kilograms, we did aortic compute tomography angiography (CTA) examinations and measured morphologic parameters of aortic root. Then we accordingly customized the valved-fenestrated-bifurcated endograft. The endograft was delivered through transapical access and endovascularly reconstructed the segment from aortic valve to proximal part of aortic arch. The overall technical success rate was 95% because of one case of delivery system failure. Instant transesophageal echography (TEE) and aortic CTA confirmed ideal position of the endograft, satisfactory function of aortic valve, and the patency of coronary arteries in all subjects. During follow-up, 12 subjects were sacrificed according to the plan and seven were followed up for 8.1±3.6 months. There was one unplanned death of cardiac infection (unplanned mortality: 5.3%). Follow-up re-examinations (aortic CTA, cardiac ultrasound, and electrocardiogram) found no adverse events. Among 12 sacrificed subjects, there was no evidence of fenestrations alignment lost and no myocardial ischemia according to the pathological analysis.
Conclusion
The novel one-piece valved-fenestrated-bifurcated endografting might be feasible for minimal-invasive reconstruction of aortic root in animal models, thus provided a prospect to simultaneously treat pathologies involving aortic valve and aortic root in endovascular way.

Abstract
Objective: To study the mutational characteristics of KCNT1 and its clinical features in children with early-onset epileptic encephalopathy. Methods: Retrospective analysis of clinical data of 175 children with early onset epilepsy from the Department of Pediatrics at Peking University First Hospital from January 2012 to December 2017. Gene-based analysis was performed on children with targeted capture second-generation sequencing and the source of mutations was verified by PCR-Sanger. The clinical features of children with KCNT1 mutation were summarized. Results: In 175 infants with early-onset epileptic encephalopathy, 6 children were found to have KCNT1 mutations, all of which were new mutations with an overall mutation rate of 3.4% (6/175). All the mutations were missense mutations. The age of onset was from 2 days to 32 days. Five children were diagnosed with epilepsy of infancy with migrating focal seizure, one case was diagnosed with epilepsy, focal seizures, focal seizures with generalization. A total of 6 children were treated with multi-antiepileptic drugs. The disease in 4 patients were partially controlled, while in 2 patients, the disease was not significantly alleviated. One patient died of "severe pneumonia" at one year and 4 months of age. Then, four cases were treated with quinidine. The seizure frequency had no change in 3 cases, the frequency decreased and then relapsed in 1 case. The case once ketogenic diet and failed. Ketogenic diet treatment was applied to 5 cases, no significant effect was achieved. All the 6 patients had severe developmental delay. They could not sit alone, follow the light and objects and had no language. Conclusions: The mutation of KCNT1 gene is mainly de novo. The onset of the disease was early, and mostly occurs in neonate and early infancy. The main seizure type was epilepsy of infancy with migrating focal seizure. Patients usually had severe psychomotor developmental delay. Antiepileptic drugs are ineffective. The efficacy of quinidine was not significant. Though, it still need studies on a large sample.

Abstract
Objective: To explore the clinical features, diagnosis, treatment and the prognosis of Farber disease by case report and literature review. Method: The clinical information of a case with farber's disease diagnosed in October 2015 at Peking University First Hospital was collected and analyzed, including clinical manifestation, electrophysiology, magnetic resonance imaging, pathology, treatments and prognosis.ASAH1 gene mutational analysis was conducted in the patient and her parents.By using "Farber's disease, ASAH1" as keywords, literature was searched from Pubmed, CHKD and HGMD database from January 1951 to January 2016. Result: The girl, 2 years 2 months old, was sent to our hospital in October 2015, with complains of "joint swelling for 17 months, development regress of intelligence and movement for 11 months, intermittent seizures for 2 months" .The clinical manifestation of the patient was characterized by painful and deformed joints, subcutaneous nodules, progressive hoarseness, and the progressive neurological system deterioration.Joints swelling and deformity behave as the first symptoms.A series of electroencephalogram showed slow background and spike wave.Visual evoked potential was significantly abnormal.Brain magnetic resonance imaging (MRI) showed hypomyelination and progressive diffuse brain atrophy.Histology of subcutaneous nodule showed proliferation of the connective tissue with hyalinization, cholesterol crystal like changes, and a large number of foamy cell infiltration.Compound heterozygous mutations of ASAH1 gene, c. 304_305 ins A (p.T102Nfs14) and c. 314T>C (p.L105p), were found in the patient, and the former is inherited from her mother, the latter from her father.Antiepileptic treatment and other symptomatic treatments were delivered to the patient, but the effectiveness was poor.One reference from China hownet and 35 references from Pubmed have reported a total of 26 cases.Twenty out of 26 patients (77%) had the onset under 1 year of age.By region, there were 12 patients (12/26, 46%) from India, and the others around world.Among these 12 indian patients, 10 lack of complete clinical data.Among the rest 16 patients, 4 patients' parents were consanguineous; 8 patients with the main clinical manifestation of painful and deformed joints, subcutaneous nodules, and hoarse cry; 4 patients with hepatic failure and impaired spleen; 5 patients with rapid neurological deterioration; 1 patient with bone destruction; 7 patients under liver and skin biopsies, pathologically showing a large number of foam cells and "Farber bodies" . There are 33 genetic mutations, and 45% (15/33) mutations are concentrated in ASAH1 exon 6-10. Conclusion: Farber disease is a rare autosomal recessive disease caused by deficiency of lysosomal acid ceramidase.Histopathology of granulomatous tissue plays an important role in the early diagnosis.

Abstract
BACKGROUND AND AIMS The objective of this study is to observe the effect of alpha-lipoic acid (ALA) on Pod injury by anti-inflammation and explore its possible renal protective mechanism. METHODS A total of 36 cases with type 2 diabetes with microalbuminuria and fasting plasma glucose (FPG) levels less than 9 mmol/L and glycated hemoglobin A1c (HbA1c) ≤9.0 % were recruited to be treated with ALA (600 mg, daily) for 6 months (group DA). Another 30 healthy individuals were chosen as normal controls (group NC). The levels of serum creatinine (Cr), FPG, and HbA1c were detected; blood pressure was recorded; and early morning urine samples (corrected for urinary Cr) were collected for the examination of urinary monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-β1 (TGF-β1), podocalyxin (PCX), nephrin, albumin and Cr in group NC and group DA at the baseline and the sixth month. RESULTS The excretions of urinary MCP-1, TGF-β1, PCX, nephrin and albumin to Cr ratio (abbreviated as UMCR, UTCR, UPCR, UNCR and UACR respectively) were significantly increased in group DA compared with group NC (all P < 0.01), and after 6-month treatment, all indexes mentioned above decreased markedly (P < 0.05), while FPG and HbA1c had no obvious changes. Additionally, there was a positive correlation between UMCR, UTCR with UPCR, UNCR and UACR, respectively (all P < 0.01). CONCLUSIONS Anti-inflammation of ALA in vivo and local kidney is implicated in the protection of glomerular Pod injury in patients with type 2 diabetes.

Abstract
In this study, conventional TiO2 powder was heated in hydrogen (H2) gas at a high temperature as pretreatment. The photoactivity of the treated TiO2 samples was evaluated in the photodegradation of sulfosalicylic acid (SSA) in aqueous suspension. The experimental results demonstrated that the photodegradation rates of SSA were significantly enhanced by using the H2-treated TiO2 catalysts and an optimum temperature for the H2 treatment was found to be of 500-600 degrees C. The in situ electron paramagnetic resonance (EPR) signal intensity of oxygen vacancies (OV) and trivalent titanium (Ti3+) associated with the photocatalytic activity was studied. The results proved the presence of OV and Ti3+ in the lattice of the H2-treated TiO2 and indicated that both were contributed to the enhancement of photocatalytic activity. Moreover, the experimental results presented that the EPR signal intensity of OV and Ti3+ in the H2-treated TiO2 samples after 10 months storage was still significant higher than that in the untreated TiO2 catalyst. The experiment also demonstrated that the significant enhancement occurred in the photodegradation of phenol using the H2-treated TiO2.

Abstract
Insulin-dependent diabetes mellitus (IDDM) is rare in Chinese children. There have been no reports on the prevalence of peripheral neuropathy in Chinese children with IDDM. This study aimed to determine prevalence of subclinical peripheral neuropathy in Chinese children with IDDM. Motor and sensory nerve conduction studies of both median, ulnar, peroneal, and tibial (motor nerves) and median, ulnar, and sural (sensory nerves) were performed in 38 children with IDDM (18 males, 20 females). The age was 4-21 years (mean = 12.7 years; median = 12 years, 6 months). The duration of diabetes was less than 5 years in 15, 5-10 years in 14, and more than 10 years in nine. Neurophysiologic evidence of subclinical peripheral neuropathy was present in 26 patients (68.4%) of which motor, sensory, or motor and sensory involvement was 26 (68.4%), eight (21.1%), and 26 (68.4%), respectively. Twelve (31.6%) and 14 (36.8%) children had mild and moderate degrees of peripheral neuropathy, respectively. Among the 26 children with abnormal nerve-conduction studies, two (7.7%) had symptoms of numbness and pain in the lower limbs. Thus, two children had symptomatic neuropathy and most (n = 24) had asymptomatic peripheral neuropathy. Two children had systemic hypertension, and one (3.8%) had laboratory evidence of early renal complications. Analysis of demographic and laboratory risk factors for the development of subclinical peripheral neuropathy revealed that the age of onset, duration of diabetes, level of hemoglobin A1c, triglyceride, cholesterol, serum creatinine, and urea, microalbumin/creatinine ratio, and urinary microalbumin excretion rate were significantly related to the development of subclinical peripheral neuropathy in specific nerves.

Abstract
The present study was undertaken to identify whether mitochondrial DNA (mtDNA) mutations were involved in the pathogenesis of Rett syndrome (RS). Mitochondrial DNA from 15 children with RS and 14 of their mothers was analyzed. No large deletions in mtDNA were found using Southern blot with a full-length mtDNA as a probe. Polymerase chain reaction amplification and single strand conformation polymorphism analysis showed mutations in region 2650-3000 encoding 16S rRNA of mtDNA in 13 cases of RS and 11 of their mothers. DNA sequence analysis and mismatch polymerase chain reaction results revealed a point mutation (C --> T) at position 2835 in 7 cases of RS and 6 of their mothers. The same mutation was not found in a total of 30 normal controls. These data indicate that mtDNA may play an important role in the pathogenesis of RS.

Abstract
The author used smear from Stensen's duct aspiration to observe exfoliated cytology in order to help diagnosis of early mumps.According to the smears from 100 cases of mumps and other 50 cases of bacteria parotitis and/or normal parotid as contro,the author revealed that if there are a lot of ductal epithelial cells,monocytes and polynuclear cells,monocytes and polynuclear phagocytes at same time,it could give diagnosis "Mumps" to that patient.In control group,it is unable to observe those three kind cells at same time.The author also discussed the mechanism of how would these three kind cells appear in mumps in accordance with references.
