Abstract
PURPOSE The FAT1 gene encodes FAT atypical cadherin 1, which is essential for foetal development, including brain development. This study aimed to investigate the relationship between FAT1 variants and epilepsy. METHODS Trio-based whole-exome sequencing was performed on a cohort of 313 patients with epilepsy. Additional cases with FAT1 variants were collected from the China Epilepsy Gene V.1.0 Matching Platform. RESULTS Four pairs of compound heterozygous missense FAT1 variants were identified in four unrelated patients with partial (focal) epilepsy and/or febrile seizures, but without intellectual disability/developmental abnormalities. These variants presented no/very low frequencies in the gnomAD database, and the aggregate frequencies in this cohort were significantly higher than those in controls. Two additional compound heterozygous missense variants were identified in two unrelated cases using the gene-matching platform. All patients experienced infrequent (yearly/monthly) complex partial seizures or secondary generalised tonic-clonic seizures. They responded well toantiseizure medication, but seizures relapsed in three cases when antiseizure medication were decreased or withdrawn after being seizure-free for three to six years, which correlated with the expression stage of FAT1. Genotype-phenotype analysis showed that epilepsy-associated FAT1 variants were missense, whereas non-epilepsy-associated variants were mainly truncated. The relationship between FAT1 and epilepsy was evaluated to be "Strong" by the Clinical Validity Framework of ClinGen. CONCLUSIONS FAT1 is a potential causative gene of partial epilepsy and febrile seizures. Gene expression stage was suggested to be one of the considerations in determining the duration ofantiseizure medication. Genotype-phenotype correlation helps to explain the mechanisms underlying phenotypic variation.

Abstract
OBJECTIVE Bone metabolism can be influenced by a range of factors. We selected children with self-limited epilepsy with centrotemporal spikes (SeLECTS) and lifestyles similar to those of healthy children to control for the confounding factors that may influence bone metabolism. We aimed to identify the specific effects of epilepsy and/or anti-seizure medications (ASMs) on bone metabolism. METHODS Patients with SeLECTS were divided into an untreated group and a monotherapy group, and the third group was a healthy control group. We determined the levels of various biochemical markers of bone metabolism, including procollagen type I nitrogenous propeptide (PINP), alkaline phosphatase (ALP), osteocalcin (OC), collagen type I cross-linked C-telopeptide (CTX), calcium, magnesium, phosphorus, parathyroid hormone (PTH), and vitamin D3 (VD3 ). RESULTS A total of 1487 patients (from 19 centers) were diagnosed with SeLECTS; 1032 were analyzed, including 117 patients who did not receive any ASMs (untreated group), 643 patients who received only one ASM (monotherapy group), and 272 children in the healthy control group. Except for VD3 , other bone metabolism of the three groups were different (p < .001). Bone metabolism was significantly lower in the untreated group than the healthy control group (p < .05). There were significant differences between the monotherapy and healthy control group in the level of many markers. However, when comparing the monotherapy and untreated groups, the results were different; oxcarbazepine, levetiracetam, and topiramate had no significant effect on bone metabolism. Phosphorus and magnesium were significantly lower in the valproic acid group than the untreated group (adjusted p < .05, Cliff's delta .282-.768). CTX was significantly higher in the lamotrigine group than in the untreated group (adjusted p = .012, Cliff's delta = .316). SIGNIFICANCE Epilepsy can affect many aspects of bone metabolism. After controlling epilepsy and other confounders that affect bone metabolism, we found that the effects of ASMs on bone metabolism differed. Oxcarbazepine, levetiracetam, and topiramate did not affect bone metabolism, and lamotrigine corrected some of the abnormal markers of bone metabolism in patients with epilepsy.

Abstract
Sirolimus is confirmed to be effective in the treatment of tuberous sclerosis complex (TSC) and related disorders. The study aims to establish a population pharmacokinetic model of oral sirolimus for children with TSC and provide an evidence-based approach for individualization of sirolimus dosing in the pediatric population. A total of 64 children were recruited in this multicenter, retrospective pharmacokinetic study. Whole-blood concentrations of sirolimus, demographic, and clinical information were collected and analyzed using a nonlinear mixed-effects population modeling method. The final model was internally and externally validated. Then Monte Carlo simulations were performed to evaluate and optimize the dosing regimens. In addition, the efficacy and safety of sirolimus therapy was assessed retrospectively in patients with epilepsy or cardiac rhabdomyomas associated with TSC. Finally, the sirolimus pharmacokinetic profile was described by a 1-compartment model with first-order absorption and elimination along with body weight and total daily dose as significant covariates. The typical population parameter estimates of apparent volume of distribution and apparent clearance were 69.48 L and 2.79 L/h, respectively. Simulations demonstrated that dosage regimens stratified by body surface area may be more appropriate for children with TSC. These findings could be used to inform individualized dosing strategies of sirolimus for pediatric patients with TSC.

Abstract
Objective: To examine the technique and effect of combined thoracic and abdominal organ clusters resection. Methods: From February 2019 to August 2021, totally 50 cases of combined thoracoabdominal organ cluster resection were completed at Transplant Medical Center, the Second Affiliated Hospital of Guangxi Medical University from donation after brain death donors. There were 47 males and 3 females, aging (34.8±12.3) years (range: 5 to 55 years). The length of hospital stay(M(IQR)) was 4(4) days (range: 2 to 43 days), the length of tube time was 4(2) days (range: 1 to 43 days). Through the midsternal incision and the abdominal grand cross incision, the cold perfusion was performing simultaneously when the perfusion lines of each target organ was established respectively. The combined resection was performed with the diaphragm as the boundary and the organ cluster as the unit. The heart and lung were separated on site and sent to the transplant hospital, and the abdominal organ cluster was directly preserved and returned to our hospital for further separation and repair. Results: Totaly 21 hearts, 47 pairs of lungs, 49 livers, 47 pairs of kidneys and 11 pancreas were harvested by this surgical treatment. The resection time was (32.6±6.5) minutes (range: 19 to 50 minutes), with no hot ischemia time. There was no accidental injury that affected organ quality and function. Heart transplantation was performed in 17 cases, combined heart-kidney transplantation in 2 cases, double lung transplantation in 43 cases, single lung transplantation in 6 cases, liver transplantation in 41 cases, combined liver-pancreas-duodenal cluster transplantation in 1 case, combined liver-kidney transplantation in 3 cases, combined pancreas-kidney transplantation in 9 cases, and kidney transplantation in 74 cases. Conclusion: Simultaneous perfusion and combined resection of thoracic and abdominal organ clusters for donation after brain death donors are feasible and effective.

Abstract
BACKGROUND Ornithine transcarbamylase deficiency (OTCD) is an X-linked inherited disorder and characterized by marked elevation of blood ammonia. The goal of treatment is to minimize the neurological damage caused by hyperammonemia. OTCD can be cured by liver transplantation (LT). Post-transplant patients can discontinue anti- hyperammonemia agents and consume a regular diet without the risk of developing hyperammonemia. The neurological damage caused by hyperammonemia is almost irreversible.
CASE SUMMARY An 11.7-year-old boy presented with headache, vomiting, and altered consciousness. The patient was diagnosed with late-onset OTCD. After nitrogen scavenging treatment and a protein-free diet, ammonia levels were reduced to normal on the third day of admission. Nevertheless, the patient remained in a moderate coma. After discussion, LT was performed. Following LT, the patient’s blood ammonia and biochemical indicators stabilized in the normal range, he regained consciousness, and his nervous system function significantly recovered. Two months after LT, blood amino acids and urine organic acids were normal, and brain magnetic resonance imaging showed a decrease in subcortical lesions.
CONCLUSION LT can significantly improve partial neurological impairment caused by late-onset OTCD hyperammonemic encephalopathy, and LT can be actively considered when early drug therapy is ineffective.

Abstract
Objective: To summarize the clinical phenotype of patients with developmental and epileptic encephalopathy 85 caused by SMC1A gene truncating variation. Methods: The clinical data of 4 patients with epileptic encephalopathy caused by SMC1A gene truncating variation from August 2016 to June 2020 were analyzed retrospectively. Related literatures up to October 2021 with the key words "SMC1A" "Developmental and epileptic encephalopathy 85" "SMC1A, epilepsy" and "SMC1A, truncating" in PubMed, CNKI, and Wanfang databases were searched. Relevant literature was summarized and reviewed. Results: These 4 patients were all female. The onset age of seizure were all in the infantile period. They were admitted to the hospital at 3, 2, 11 and 18 months respectively. Focal seizures occurred in all 4 patients, while 1 of them experienced infantile spasm. The characteristic of cluster was observed in all of them with an interval of 14 days to 5.0 months. The seizures were all refractory to different kinds of anti-seizure medications. All 4 patients had severe developmental retardation with microcephaly (head circumference<-2 s). The interictal electroencephalogram (EEG) was characterized by diffuse slow wave. The 4 SMC1A gene variants were p.Gly655fs, p.Glu811fs, p.Arg412fs and p.Ile143fs, all of which were de novo frameshift variation after parental validation. There were another 17 cases with SMC1A gene truncating variation reported in 6 English articles and 1 Chinese article. Among these 21 patients, who were all female, the onset of seizures occurred between 0.5 and 18.0 months of age. Seventeen cases (81%) had the characteristics of cluster attacks, and the intervals of attack cycles were different. Seizure types included generalized tonic-clonic seizure (12 cases (57%)), focal seizure (11 cases(52%)), myoclonic(4 cases(19%)), spasm (4 cases(19%)), atypical absence (3 cases(14%)), tonic seizure (2 cases (10%)), and atonia (1 case(5%)). In addition, 4 cases (19%) had status epilepsy. All patients had moderate to severe mental retardation. Microcephaly was found in all patients. Among 18 cases,EEG in 8 cases had diffuse slow wave background. Brain magnetic resonance imaging (MRI) was normal in 13 cases (62%). Other MRI changes included cerebellar atrophy (3 cases), thin corpus callosum (3 cases), and lateral ventricular enlargement (2 cases). Twenty patients did not respond well to antiepileptic drugs. Conclusions: The clinical phenotypes of patients with epilepsy encephalopathy 85 caused by SMC1A gene truncating variation are characterized by female, early-onset, clustering of seizures, development delay and microcephaly. Diffuse slow waves are shown in interictal EEG in partial. Response to treatment and prognosis are poor.

Abstract
Objective: To summarize the clinical characteristics of children with interleukin-1 receptor associated kinase 4 (IRAK4) deficiency. Methods: The clinical data of a child with IRAK4 deficiency who was admitted to the Department of Neurology of Shenzhen Children's Hospital for several times from June 2019 to August 2020 were retrospectively analyzed. Related literature up to January 2021 with the key words "IRAK4 gene variation", and "interleukin-1 receptor-associated kinase 4 deficiency" in PubMed, CNKI, Wanfang, and CQVIP databases were searched. The clinical characteristics of this disease were summarized and analyzed. Results: The boy was 6 years of age and had recurrent respiratory tract infections. He was improved after antibiotic treatment. His clinical manifestation included Streptococcus pneumoniae meningoencephalitis, multiple sclerosis, invasive discitis and inflammatory bone destruction. Family-based whole exome sequencing showed that the boy had a homozygous frameshift variation in the IRAK4 gene, NM_016123.3:C.540del (p.Phe180leufs*26), and both parents were heterozygous. A total of 23 cases were reported in ten English articles. Together with this case, there were 24 cases, including 13 males and 11 females. The age of onset was 8 days to 7 years. The main manifestations were recurrent invasive bacterial infection, including 11 cases with Streptococcus pneumoniae meningitis, 9 cases with Streptococcus pneumoniae and (or) Staphylococcus aureus septicemia, 1 case with Pseudomonas aeruginosa meningitis, 1 case of salmonella infection, and 1 case with Staphylococcus aureus skin abscess. Only 1 case had recurrent virus infection. There were 2 patients with autoimmune diseases, 1 with autoimmune encephalitis and the other one with juvenile idiopathic arthritis. Among the 24 cases, 10 died (9 in infancy). Most of the surviving children were diagnosed early and received antibiotics preventively and intravenous immunoglobulin (IVIG). Their susceptibility to infection decreased year by year, and could be close to normal children at the age of 14 years. Among the 24 cases, 21 cases had homozygous variation of IRAK4 gene and 3 cases had complex heterozygous variation. There were 15 kinds of variation, including 9 kinds of frameshift variation, 4 kinds of nonsense variation and 2 kinds of missense variation. One candidate variation hotspot was c.877 c>T (3 cases). Conclusions: IRAK4 deficiency mainly manifest as recurrent and invasive bacterial infection, with Streptococcus pneumoniae meningitis or septicemia being the most common. A few patients are complicated with autoimmune diseases. The mortality rate is high in infancy, early diagnosis and treatment can avoid severe illness or death.

Abstract
The effect of the chemical component and microstructure, not to mention their facile modification, of the coating/wrapping carbon layer on the electrochemical performance of the Si/C composite anode in lithium ion batteries (LIBs) hasn't been actively explored although Si/C has been recognized as one of the most promising route for the high energy density LIBs. Herein we propose a novel nitrogen-plasma doping route to modify the top carbon film in an elaborately constructed layered Si/C composite anode. The electrochemical performance, e.g., the initial coulombic efficiency (CE), cycle stability and specific capacity of the composite anode is drastically improved by this plasma processing due to the increased kinetics of lithium ions. By means of the appropriate adjustment of the N doping ratio and N chemical configuration in the carbon layer through a N2/H2 plasma processing, the lithium diffusion rate in the composite anode was memorably increased as the pseudocapacitance effects promoted. The optimized Si/C composite exhibits a high capacity of 1120.7 mA h g-1 and an initial CE of 80.8% at the current of 2 A g-1 after a long cycle of 1500, increasing by ~40% of specific capacity and ~29% of the initial CE.

Abstract
Infantile hypertonic myofibrillar myopathy is characterized by the rapid development of rigid muscles and respiratory insufficiency soon after birth, with very high mortality. It is extremely rare, and only a few cases having been reported until now. Here we report four Chinese infants with fatal neuromuscular disorders characterized by abdominal and trunk skeletal muscle stiffness and rapid respiratory insufficiency progression. Electromyograms showed increased insertion activities and profuse fibrillation potentials with complex repetitive discharges. Immunohistochemistry staining of muscle biopsies showed accumulations of desmin in the myocytes. Powdery Z-bands with dense granules across sarcomeres were observed in muscle fibers using electron microscopy. All patients carry a homozygous c.3G>A mutation in the CRYAB gene, which resulted in the loss of the initiating methionine and the absence of protein. This study's findings help further understand the disease and highlight a founder mutation in the Chinese population.

Abstract
Objective: To explore the clinical characteristics of pediatric glucose transporter type 1 deficiency syndrome (GLUT1 DS), evaluate the efficacy and safety of ketogenic diet therapy (KDT). Methods: Clinical data of 19 children with GLUT1 DS admitted to Children's Hospital of Fudan University, Tianjin Children's Hospital, Shenzhen Children's Hospital, Children's Hospital of Nanjing Medical University and Jiangxi Provincial Children's Hospital between 2015 and 2019 were collected retrospectively. The first onset symptom, main clinical manifestations, cerebrospinal fluid features and genetic testing results of patients were summarized, the efficacy and safety of ketogenic diet treatment were analyzed. Results: Among the 19 cases, 13 were males and 6 females. The age of onset was 11.0 (1.5-45.0) months,the age of diagnosis was 54.0 (2.8-132.0) months. Epilepsy was the first onset symptom of 13 cases. Different forms of tonic-clonic seizures were the most common types of epilepsy (7 cases with generalized tonic-clonic seizures, 5 cases with focal tonic or clonic seizures, 4 cases with generalized tonic seizures). Antiepileptic drugs were effective in 4 cases. Paroxysmal motor dysfunction was present in 12 cases and ataxia was the most common one. All patients had different degrees of psychomotor retardation. Among 17 patients received cerebrospinal fluid examination, cerebrospinal fluid (CSF) glucose level was lower than 2.2 mmol/L and CSF glucose/glycemic index was<0.45 in 16 cases, only 1 case presented normal CSF glucose level (2.3 mmol/L) and normal CSF glucose/glycemic index(0.47). SLC2A1 gene mutations were found in 16 patients, missense, frameshift and nonsense mutations were the common types with 5 cases, 5 cases and 3 cases respectively. All 19 patients were treated with ketogenic diet, which was effective in 18 cases in seizure control, 11 cases in dyskinesia improvement and 18 cases in cognitive function improvement. No serious side effects were reported in any stage of KDT. Conclusions: The diagnosis of GLUT1 DS is often late. It is necessary to improve the early recognition of the disease and perform CSF glucose detection and genetic testing as early as possible. The KDT is an effective and safe treatment for GLUT1 DS, but a small number of patients have not response to diet therapy.

Abstract
Objective: To explore the clinical characteristics of intellectual developmental disorder with cardiac arrhythmia syndrome (IDDCA) in a family caused by GNB5 gene variation and to review the literature. Methods: The clinical and genetic data of an infant with IDDCA, who visited Shenzhen Children's Hospital in September 2018, were collected and analyzed. His parents' and brother's gene analysis was also done by the next-generation sequencing and confirmed by Sanger sequencing. Related literature up to March 2020 was searched in Online Mendelian Inheritance in Man (OMIM), PubMed, CNKI and Wanfang databases with "GNB5" "IDDCA" "LADCI" "intellectual developmental disorder with cardial arrhythmia" "language delay and attention deficit-hyperactivity disorder or cognitive impairment with or without cardiac arrhythmia" as the key words. The related papers were retrieved and analyzed to summarize the clinical and genetic characteristics of this disorder. Results: The proband was an 11-month-old boy who presented with mental and motor developmental retardation, accompanied with convulsion and muscle weakness. Sinus arrest was also detected. His electroencephalogram (EEG) and flash visual evoked potential (FVEP) were both abnormal. Genetic analysis identified the homozygous frameshift variation of GNB5 gene (c.136delG, p.Glu46Argfs*8) in this infant and heterozygous variation in his parents, confirmed the diagnosis of IDDCA. The same GNB5 variation was identified in his brother, who was 4 years and 8 months old and had developed the similar clinical manifestations after birth. There were only 7 papers reporting this disease in the literature review, with a total of 27 patients from 14 families. Including these 2 cases, there were 29 patients in total, whose age of diagnosis ranged from 5.5 months to 23 years. Among all the patients, 20 cases (69%) were diagnosed as IDDCA, while 8 cases (28%) as LADCI; and 11 (38%) were males while 18 (62%) females. Regarding the clinical features, 66% (19/29) had mental retardation, 41% (12/29) had seizures, 79% (23/29) developed language delay and 62%(18/29) had sinus node dysfunction. Genetic tests showed that 4 patients from 3 families had complex heterozygous variation, and 25 patients (86%) from 12 families had homozygous variation. Seventeen patients from 8 families were consanguineous. Among the total 12 variations, there were 4 nonsense, 3 frameshift, 2 missense and 2 shear mutations, and 1 shear disorder caused by synonymous mutation. Conclusions: IDDCA caused by GNB5 gene variations mainly manifests as general developmental delay or severe mental retardation, and sinus node dysfunction. GNB5 associated syndromes have phenotypic heterogeneity and are inherited in an autosomal recessive manner.

Abstract
Benthic fauna refers to all fauna that live in or on the seafloor, which researchers typically divide into size classes meiobenthos (32/64 µm-0.5/1 mm), macrobenthos (250 µm-1 cm), and megabenthos (>1 cm). Benthic fauna play important roles in bioturbation activity, mineralization of organic matter, and in marine food webs. Evaluating their role in these ecosystem functions requires knowledge of their global distribution and biomass. We therefore established the BenBioDen database, the largest open-access database for marine benthic biomass and density data compiled so far. In total, it includes 11,792 georeferenced benthic biomass and 51,559 benthic density records from 384 and 600 studies, respectively. We selected all references following the procedure for systematic reviews and meta-analyses, and report biomass records as grams of wet mass, dry mass, or ash-free dry mass, or carbon per m2 and as abundance records as individuals per m2. This database provides a point of reference for future studies on the distribution and biomass of benthic fauna.

Abstract
Tremendous efforts have been made to improve the electrochemical performance of the lithium-sulfur batteries. However, challenges remain in achieving fast electronic and ionic transport while accommodate the significant cathode volumetric change. On the other hand, the severe capacity decay mainly attributed to polysulfide shuttle also hampers the practical applications. Here, we report a simple, low-cost, and eco-friendly method for the one-step preparation of a binder-free S-C composite cathode by plasma dissociation of CS2 containing gases at room-temperature. The key issue of polysulfide shuttle effect in Li-S batteries is also effectively resolved just by the introduction of N2 into the precursor gases. The electrode exhibits a high reversible capacity of ~600 mAh/g of the total hybrid of S + C at 100 mA/g after 100 cycles with an excellent initial coulombic efficiency of nearly 100%. The cells also demonstrate along cycle life and an extremely high capacity of ~306 mAh/g even after 300 cycles at 1 A/g with a high coulombic efficiency of about 100%. The proposed method will open the way for the plasma applications in facile preparation of Li-S batteries and the improvement of its electrochemical performance.

Abstract
Lysinuric protein intolerance (LPI) is an autosomal recessive disorder caused by SLC7A7 gene mutation and often involves severe lesions in multiple systems. Lung involvement is frequently seen in children with LPI and such children tend to have a poor prognosis. This article summarizes the clinical manifestations and gene mutation characteristics of three children diagnosed with LPI by SLC7A7 gene analysis. All three children had the manifestations of aversion to protein-rich food after weaning, delayed development, anemia, hepatosplenomegaly, and osteoporosis, as well as an increase in orotic acid in urine. In addition, interstitial pneumonia and diffuse pulmonary interstitial lesions were observed in two children. SLC7A7 gene detection showed three pathogenic mutations in these children, namely c.1387delG(p.V463CfsX56), c.1215G>A(p.W405X) and homozygous c.625+1G>A. After a definite diagnosis was made, all three children were given a low-protein diet and oral administration of citrulline [100 mg/(kg.d)], iron protein succinylate [4 mg/(kg.d)], calcium and zinc gluconates oral solution (10 mL/day) and vitamin D (400 IU/day). In addition, patient 3 was given prednisone acetate (5 mg/day). The children had varying degrees of improvement in symptoms and signs. It is hard to distinguish LPI from urea cycle disorder due to the features of amino acid and organic acid metabolism in LPI, and SLC7A7 gene analysis is the basis for a definite diagnosis of LPI.

Abstract
AIM To investigate whether patients with refractory epilepsy and healthy infants differ in gut microbiota (GM), and how ketogenic diet (KD) alters GM.
METHODS A total of 14 epileptic and 30 healthy infants were recruited and seizure frequencies were recorded. Stool samples were collected for 16S rDNA sequencing using the Illumina Miseq platform. The composition of GM in each sample was analyzed with MOTHUR, and inter-group comparison was conducted by R software.
RESULTS After being on KD treatment for a week, 64% of epileptic infants showed an obvious improvement, with a 50% decrease in seizure frequency. GM structure in epileptic infants (P1 group) differed dramatically from that in healthy infants (Health group). Proteobacteria, which had accumulated significantly in the P1 group, decreased dramatically after KD treatment (P2 group). Cronobacter predominated in the P1 group and remained at a low level both in the Health and P2 groups. Bacteroides increased significantly in the P2 group, in which Prevotella and Bifidobacterium also grew in numbers and kept increasing.
CONCLUSION GM pattern in healthy infants differed dramatically from that of the epileptic group. KD could significantly modify symptoms of epilepsy and reshape the GM of epileptic infants.

Abstract
PURPOSE The ketogenic diet (KD) is an effective treatment for intractable epilepsy (IE), however the therapeutic mechanism is still unclear. This study was designed to investigate T helper type 17/regulatory T cell (Th17/Treg) levels in children with IE and age-matched healthy controls following KD. METHOD Circulating levels of Th17/Treg cells were analyzed by flow cytometry. Plasma concentration of interleukin (IL)-17 was measured by cytometric bead array assay. Real-time PCR was performed to measure mRNA levels of mTOR, HIF1α and Th17/Treg associated factors in purified CD4(+)CD25(+) T and CD4(+)CD25(-) T cells. RESULTS By one-way ANOVA, the proportion of circulating Th17 cells and expression of IL-17A and RORγt were significantly higher (P<.05), while the proportion of circulating Tregs and expression of Foxp3, GITR, CTLA-4 were significantly lower (P<.05) in IE patients than healthy subjects. However, these alternations were reversed following KD (P<.05). In CD4(+)CD25(+) T and CD4(+)CD25(-) T cells mTOR and HIF1α expression were significantly higher in IE patients (P<.05), however KD reduced mTOR and HIF1α expression (P<.05). The plasma IL-17A concentrations were higher in IE patients than controls (P<.05). KD partially reduced IL-17A levels (P<.05). CONCLUSION Our results suggest that Th17/Treg imbalance is characteristic of childhood IE, and may contribute to IE pathogenesis. KD treatment is able to correct this imbalance, probably via inhabiting the mTOR/HIF-1α signaling pathway.

Abstract
OBJECTIVE To investigate the changes in brain injury after the induction chemotherapy in children with acute lymphoblastic leukemia (ALL) by cranial MRI. METHODS The clinical data and cranial MRI results of 62 children with ALL who were hospitalized from March 2014 to June 2015 were analyzed retrospectively. RESULTS Before chemotherapy, MRI showed bone marrow infiltration of the skull in 33 patients (53%); the children with WBC<20×10(9)/Lhad a significantly lower incidence rate of bone marrow infiltration of the skull than those with WBC≥20×10(9)/L (16 patients/42% vs 17 patients/71%; P<0.05), and the high-risk group had a significantly higher incidence rate of bone marrow infiltration of the skull than the non-high-risk group (71% vs 44%; P<0.05). Before chemotherapy, there were 4 cases (7%) of brain atrophy, and 2 cases (3%) of abnormal signals in the sensory conduction bundle. MRI reexamination in 28 patients after 3 months of chemotherapy showed 3 new cases (11%) of brain atrophy and 1 aggravated case of brain atrophy. CONCLUSIONS The children with ALL have bone marrow infiltration of the skull, brain atrophy, and abnormal signals in the sensory conduction bundle before chemotherapy, especially bone marrow infiltration of the skull, and some changes in brain injury disappear after treatment.

Abstract
BACKGROUND Seagrass beds are highly diverse and productive marine habitats for many associated organisms in nearshore coastal waters. The differences in abundance, diversity, and community structure of benthic invertebrates between seagrass beds and adjacent unvegetated sediments have been stated, whereas most studies are primarily focused on macrofauna or based on a comparatively long distance, i.e., more than 10 m. The present study is designed to test if the community structures of meiofauna, especially the free-living nematodes, differ between seagrass beds and adjacent unvegetated sediments on a meter scale. RESULTS There are 21 meiofaunal taxa and 63 nematode genera that have been identified from a tropical seagrass bedof Thalassia hemprichii inLudao, Taiwan. Although the compositions of higher meiofaunal taxa are undistinguished, according to correspondence analysis, the assemblages of nematode genera differ substantially between the seagrass bed and unvegetated sediments. Regarding the nematodes, approximately 50% of genera are restricted to the seagrass bed whereas 6% are restricted to unvegetated sediments, which indicate both habitats possessing distinct infaunas. The number of replicates for reasonable estimation of the local diversity index is calculated by the randomization technique. For local seagrass beds, only a single core is sufficient for reliably estimating meiofaunal diversity, but at least three cores or a sample size of 300 individuals is needed for the nematode community. CONCLUSIONS Nematode assemblages provide more particular differences between seagrass and unvegetated habitats than meiofaunal communities on small spatial scales. Both seagrass beds and adjacent unvegetated sediments harbor specific meiofaunal communities, and hence, the conservation strategy for seagrass should also consider the peripheral bare area of seagrass beds.

Abstract
OBJECTIVE To study the alterations of follicular T helper cells (CD4(+)CXCR5(+)Tfh cells, Tfh) on circulating T lymphocytes in children with asthma, and to study the expression of transcription regulatory factors BCL-6 and BLIMP-1 mRNA. METHODS Sixty-four children with asthma and 25 healthy controls were enrolled in this study. On the basis of the disease, the children with asthma were classified into acute phase group (n=36) and remission phase group (n=28). The flow cytometry was used to detect the proportion of CD4(+)CXCR5(+)Tfh cells on CD4(+)T lymphocytes. Real-time PCR was performed to detect the levels of BCL-6 mRNA and BLIMP-1 mRNA. The double -antibody Sandwich ELISA was used to detect plasma concentrations of total IgE, IL-2, IL-6 and IL-21. RESULTS The proportion of CD4(+)CXCR5(+)Tfh cells was significantly higher in the acute group than in the control group and the remission group (P<0.05). Transcription levels of BCL-6 mRNA were significantly higher, while the inhibitory factors BLIMP-1 mRNA was significantly lower in the acute group than in the remission group and control group (P<0.05). The plasma concentration of IL-6 in the acute group increased significantly compared with the control group (P<0.05). Plasma concentrations of total IgE and IL-21 increased significantly, in contrast, plasma IL-2 concentration decreased significantly in the acute group, compared with the control group and the remission group (P<0.05). Correlation analysis showed that both IL-21 and IL-6 concentrations were positively correlated with the proportion of CD4(+)CXCR5(+)Tfh cells (r=0.76, r=0.46 respectively; P<0.05), while IL-2 level was negatively correlated with the proportion of Tfh cells (r=-0.68, P<0.05). CONCLUSIONS The abnormal proportion of CD4(+)CXCR5(+)Tfh cells might be involved in the immunological pathogenesis of acute asthma in children. The increased expression of BCL-6 mRNA and decreased expression of BLIMP-1 mRNA as well as the alterations of plasma total IgE, cytokines IL-2, IL-6 and IL-21 in microenvironment might be account for the increased proportion of CD4(+)CXCR5(+)Tfh cells in children with acute asthma.

Abstract
PURPOSE Oxcarbazepine (OXC) is a promising alternative for patients who cannot tolerate carbamazepine. Recently, however, it has been reported that OXC-induced cutaneous adverse drug reactions (cADRs) are prevalent and may lead to drug discontinuation. Additionally, these reactions are thought to be associated with HLA-B*1502. This study aims to investigate the incidence, features and risk factors of OXC-cADRs, and to explore their relation to HLA-B alleles in Southern Han Chinese. METHODS A prospective study was performed to investigate the incidence, features and risk factors of OXC-cADRs, in which 252 new users were recruited. To examine the association between OXC-cADRs and HLA-B alleles, 14 maculopapular eruption (MPE) cases, including 9 additional cases beyond this prospective observation, were genotyped by PCR-SSP and sequencing. Thirty-five OXC-tolerant patients served as controls. RESULTS Five patients (2.0%) developed an OXC-cADR, and all were mild MPE. History of other AED allergy (p=0.005, OR=121.23) and non-AED allergy (p=0.006, OR=59.92) were significant risk factors for OXC-cADRs in multivariate logistic regression analysis. Only one patient with OXC-MPE was positive for HLA-B*1502; and the frequency of HLA-B*1502 in OXC-MPE did not differ significantly from that in OXC-tolerant controls. Four HLA-B*1302 alleles were detected in OXC-MPE cases, which was significantly different from that in general population of southern Han Chinese (p=0.001, OR=7.83). CONCLUSIONS The incidence of OXC-induced cADRs was low, and no severe reactions occurred. Patients with a history of allergy are more susceptible to OXC-cADRs. No significant association between HLA-B*1502 and OXC-MPE was found. The associations between OXC-MPE and HLA alleles warrant further studies.

Abstract
OBJECTIVE Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) which resulted from mutation in SLC25A13 gene can present transient intrahepatic cholestasis, low birth weight, growth retardation, hypoproteinemia and so on. This study aimed to identify the mutation type of NICCD patients by DNA sequencing. METHODS Twenty children diagnosed as NICCD were consented to enroll in this study. PCR assays were performed to amplify the eighteen exons and its flanking sequences of SLC25A13 gene, which were defined as the upstream and downstream 50 bp from starting and ending site of the exons. Then the PCR products were purified and followed by automated DNA sequencing. The IVS16ins3kb mutation was detected by nested PCR and RT-PCR. RESULTS Seven genetic variations of SLC25A13, termed as 851del4, 1638ins23, IVS16ins3kb, IVS6+5G>A, c.775C>T (p.Q259X), c.1505C>T (p.P502L) and c.1311C>T (p.C437C), were identified in the subjects, of which c.775C>T (p.Q259X), c.1505C>T (p.P502L) and c.1311C>T (p.C437C) were reported for the first time in NICCD patients. And a compound mutation of[1638ins23+IVS16ins3kb]was also identified. In 20 patients with NICCD, 6 patients were 851del4 homozygotes, 7 patients were compound heterozygotes, and 7 patients were heterozygotes of single mutation. 851del4 was the major mutation type (64%), followed by 1638ins23 (15%), IVS16ins3kb (12%) and IVS6+5G>A (6%). CONCLUSIONS 851del4 is the major mutation type in Chinese patients with NICCD.

Abstract
OBJECTIVE To investigate the pathogenesis, clinical characteristics and treatment of benign infantile convulsions with mild gastroenteritis (BICG). METHODS The clinical manifestations and laboratory findings were observed in 40 children with BICG. The antigen and antibodies of rotavirus and calicivirus in stool and cerebral spinal fluid (CSF) were tested by the golden standard method and ELISA. The neurological outcome was evaluated by a follow-up of six months or more. RESULTS All of the 40 children had mild gastroenteritis with or without minor dehydration. Cluster convulsions were observed in these children. There were normal findings in blood biochemistry (Na+, K+, Ca2+, Cl-, HCO3-, glucose) and cerebral CT or MRI examinations. The interictal EEG showed sprinkle central or frontal epileptiform discharges in 8 children; clear central and parietal epileptiform discharges in 1 child; and no abnormal findings were observed in the other 31 children. Positive rotavirus antigen was detected in 11 children and positive calicivirus antigen in stool samples in 4 children. Positive antibodies of rotavirus and calicivirus in CSF were not seen. Seizures recurred in 22 of 28 children who received prophylactic injections of phenobarbital(5-10 mg/kg). In a 6 months follow-up, one child developed epilepsy and the other 39 children had no seizures and neurological sequelae. CONCLUSIONS The digestive system manifestations are mild in children with BICG. Convulsions are always clustered in these children. The mechanism underlying convulsions is not clear. Conventional dose of phenobarbital is not effective for prevention of seizures. Most of children with BICG have a good prognosis.

Abstract
OBJECTIVE To evaluate of the efficacy and safety of adjunctive levetiracetam (LEV) in children younger than 4 years with refractory epilepsy. METHODS One hundred and twelve children at age of 4 months to 4 years with refractory epilepsy received LEV as adjunctive therapy. LEV was administered in two equal daily doses of 10 mg/kg. The dose was increased by 10 mg/kg every week up to the target dose (20-40 mg/kg). The efficacy and tolerability were evaluated. RESULTS At an average follow-up period of 13 months (6-22 months), LEV administration was found to be effective in 43 children (38.4%) (responders showing more than a 50% decrease in seizure frequency) and 14 children (12.5%) became seizure-free. Fifty-three children (47.3%) did not respond to the treatment and 2 children (1.8%) worsened. The therapy-related adverse events were mild, including restlessness, reduction in sleep time, night terrors, debility, somnolence, nausea and vomiting. The adverse events were either tolerable or resolved in time with dosage reduction in most of children, and only 3 cases required discontinuation. CONCLUSIONS LEV as adjunctive therapy is effective and well-tolerated in children younger than 4 years with refractory epilepsy, suggesting that it represents a valid option for the treatment of refractory epilepsy in this age group.

Abstract
OBJECTIVE To investigate the treatment outcome and risk factors for intractable seizures in children with tuberous sclerosis complex(TSC)complicated by epilepsy. METHODS The medical data of 66 cases of TSC were retrospectively studied. RESULTS Of the 66 children with TSC, 47 cases were available for follow-up. The follow-up period ranged from 7 months to 9.3 years (average 4.5 + or - 2.6 years). The patients' present average age was (7.7 + or - 4.1) years (median 8 years). Among the 47 cases, 19 (40%) had infantile spasms, 24 (51%) had tonic seizures, 15 (32%) had partial seizures, and 3 (6%) had tonic-clonic seizures, and additionally, multifocal seizures, atonic seizures, atypical absence seizures and hypomotor seizures each appeared in 1 case (2%) respectively. The average number of antiepileptic drugs used was 1.9 + or - 0.86 (median 1). Among the 47 patients, 12 (26%) still had epileptic seizures and 33 (70%)were seizure-free, and 4% were dead. Three cases underwent surgery and continued to receive medication after surgery. The three patients were seizure-free in a 1.5 years follow-up. Among the 30 children over 7 years old, 17 cases (57%) were enrolled in ordinary schools, 3 cases (10%) in special schools and the other 10 cases were off-school for disabilities of intelligence and speech. The non-conditional logistic regression showed that the age of onset (RR=1.8, 95% CI 1.0- 3.2, P=0.050), administration of multiple antiepileptic drugs (RR=4.8, 95% CI 1.2-18.6, P=0.024), tonic seizures (RR=0.003, 95% CI 0.0- 0.2, P=0.04) and sex (RR=0.016, 95% CI 0.0-0.5, P=0.017) were risk factors for intractable seizures. CONCLUSIONS The majority (70%) of children with TSC complicated by epilepsy can be seizure-free with suitable treatment. The risk factors of poor outcome in seizure control may involve in the early onset age, tonic seizures and the administration for multiple anti-epileptic drugs.

Abstract
OBJECTIVE To compare the efficacy of valproic acid (VPA) and lamotrigine as a monotherapy for absence epilepsy in children. METHODS A randomized, open-label design was used. Childhood absence epilepsy was diagnosed based on the presence of typical seizures and video-EEG findings. Eligible patients were randomly treated with VPA or lamotrigine. All patients were followed up for 12 months. RESULTS Forty-five out of 48 eligible children completed the study. There were 23 children in the VPA group and 22 children in the lamotrigine group. Seventeen children were seizure-free in the VPA group 12 months after treatment. Fifteen out of the 17 children showed normal EEG (no epileptic-formed discharge). Twelve children were seizure-free in the lamotrigine group 12 months after treatment. The proportion showing normal EEG in the lamotrigine group (6/22, 27.3%) was significantly lower than that in the VPA group (15/23, 65.2%) (P<0.05). Severe adverse effects were not found in both groups. CONCLUSIONS Both VPA and lamotrigine are safe and efficacious for treatment of absence seizures in children. VPA appears to be better than lamotrigine in tapering epileptic-formed discharge.

Abstract
OBJECTIVE To study the features of interictal epileptiform discharges (IED) during sleep and wakefulness in children with epilepsy. METHODS The polysomnography, active EEG and video EEG were performed on 48 children with epilepsy during the whole night, and wakefulness of pre- and post-sleep. The epileptiform sharp/spike discharge indexes during sleep and wakefulness were recorded. The positive rate of IED in focal and generalized epilepsy was compared. RESULTS Of the 48 patients, 25 showed IED, including 9 cases (36.0%) in the generalized seizure group and 16 cases (64.0%) in the focal seizure group (P<0.05). The epileptiform sharp/spike discharge indexes in the whole non-rapid eye movement (NREM) sleep stage (stages S1-S4: 21.13+/-19.96, 19.59+/-17.76, 22.85+/-18.99, and 20.37+/-16.63) were significantly higher than that in the wakefulness stage (8.20+/-6.21) (P<0.05). The discharge index in the S3 stage during NREM sleep was higher than that during the rapid eye movement (REM) sleep (22.85+/-18.99 vs 12.91+/-10.95; P<0.05). CONCLUSIONS The positive rate of IED in the focal seizure group was higher than that in the generalized seizure group. Sleep, especially NREM sleep, facilitates IED in children with epilepsy.

Abstract
OBJECTIVE P-glycoprotein 170 (P-gp) is a plausible biologic candidate for pharmacoresistance in epilepsy. The expression and efflux efficiency of P-gp is influenced by a polymorphism (C3435T) in the encoding gene (MDR1). The CC genotype at the MDR1 C3435T polymorphism was reported to be associated with the response to antiepileptic drug treatment. This study attempted to replicate this finding by examining the association of this genetic polymorphism with response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy. METHODS Two hundred and fourteen ethnic Han Chinese children with epilepsy were classified based on the response to antiepileptic drug treatment: drug-nonresponsive and drug-responsive. DNA samples were obtained from the patients. Genotypes of the C3435T polymorphism were determined by traditional polymerase chain reaction followed by restriction digestion (PCR-RFLP). The frequency of genotypes and alleles between the two groups was compared by Chi-square test. RESULTS Of the 214 patients, 164 were drug-responsive and 50 were drug-nonresponsive. There were no significant differences in the allele frequency and genotype frequency between the two groups. CONCLUSIONS There is no an association between the CC genotype or C allele at the locus of C3435T in MDR1 gene and response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy.

Abstract
Mechanisms underlying tolerance to and dependence on the anticonvulsant effect of clonazepam are not clear. Autoradiography of the NMDA receptors in amygdala-kindled rats with tolerance to and dependence on the anticonvulsant effect of clonazepam was carried out. When tolerance developed, the binding of [3H] TCP (N-(1-thieny) cyclohexylpiperidine) to NMDA receptors was found to be increased at the polymorphocellular layer of the right CA1, and decreased at the molecular layer of the cerebellar ansiform lobule. On day 7 of the discontinuation of clonazepam, the binding did not change further. These changes may be responsible for the tolerance to and dependence on the anticonvulsant effect of clonazepam. However, the exact significance of these results should be further investigated.

Abstract
The stroma layer (SL) cultured from mouse bone marrow cells for one week, had an inhibitory effect on the granulocyte-macrophage progenitor cells (CFU-GM). The inhibitory effect decreased in the 2nd week SL, while the 3rd week SL promoted CFU-GM growth greatly. When indomethacin (1 x 10(-7) mol/L) was added into the CFU-GM culture system, the score of CFU-GM on the 1st week SL was raised, and on the 2nd week SL was further increased significantly, but it leveled off on the 3rd week SL. The addition of exogenous 10(-8) mol/L PGF1 suppressed the CFU-GM growth on all the 1st to 3rd week SLs. When 1 x 10(-8) mol/L PGE1 was added with 2 x 10(-7) mol/L indomethacin, 1st week SL-CFU-GM increased to 42.61%, 2nd week SL-CFU-GM nearly to 100% of the control. For the 3rd week SL-CFG-GM, 1 x 10(-7) mol/L indomethacin was enough to reverse the inhibition induced by exogenous 1 x 10(-8) mol/L PGE1. It is suggested that definite amount of PGE was produced from cells in the 1st week SL. The secretion of PGE from SL was reduced during 2nd week, and almost stopped in the 3rd week SL. The results indicate that the modulation of granulopoiesis by marrow stroma is, at least partly, mediated by PGE.
