The dendritic cell(DC) has the most powerful function among the antigen presenting cells known hitherto,which stimulates naive T cells and plays a pivotal role in inducing T cell tolerance.The role of DC in rheumatoid arthritis(RA) has aroused more and more attention.This article reviews the role of DC in RA and the researches on the drug intervention in its treatment.

ObjectiveTo provide evidence for the development of national norm of coping style for petrol station employee.MethodsStratified random sampling surveys and individual interview were performed in 13 269 in-service petroleum employees.Taking gender,age,education level and marriage as independent variables and coping factors as dependent variables,t test or analysis of variance was completed.Results Our data indicated that coping style was significantly changed in different gender ( P＜0.05),age (F=4.596,P＜0.05),education (F=14.723,P＜0.05) and marriage groups (P＜0.05).Conclusion Specified working environment results in corresponding coping style,and the development of national norm may be important and necessary.

Objective To evaluate the predictive role of TEL/AML1 fusion gene in protocol CCLG-ALL-2008 and to identify relevant factors influencing the outcome of ALL with TEL/AML1 fusion gene. Methods Ninety-nine patients with ALL harboring TEL/AML1 fusion gene (positive) and 329 cases without any specific fusion genes (negative) at diagnosis of B-lineage ALL from June 2008 to December 2014 were enrolled and their clinical and biological features were analyzed. Following-up ended in October 2015, the survival status was calculated by K-M curve and prognostic factors were analyzed by COX model. Results There were no differences between the two groups in age, white blood cell at the diagnostic stage, and treatment responses at 4 time points, namely, prednisone good response on day 8, M3 status of BM on D15, and the minimal residual disease (MRD) more than 1.0×10-3 on day 33 and 12th week. During the follow-up period, the relapse rate was lower in the positive group than that in the negative group (14/99 vs 69/329), the mortality rate of the negative group was twice of that in the positive group (55/329 vs 8/99). The five-year overall survival (OS) rate, relapse-free survival (RFS) rate and event-free survival (EFS) rate of the positive group were (86.1 ± 4.9)%, (80.7 ± 5.1)% and (78.9 ± 5.1)%, respectively, and (79 ±2.8)%, (72± 3.1)%, and (69.6+ 3.1)% for the negative group as well. COX regression analysis indicated that relapse and MRD level at the 12th week were independent prognostic factors on OS, RFS, and EFS (P<0.05) for the two groups. Conclusions TEL/AML1 fusion gene could be regarded as a relatively good indicator of risks in ALL children treated by CCLG-ALL-2008 protocol. ALL patients with TEL/AML1 are recommended to receive more intensive therapy including hematopoietic stem cell transplantation when the patients were high level of MRD on the 12th week after treatment.

Objective:To evaluate the long-term safety, tolerability and efficacy of Lacosamide add-on therapy in Chinese children with partial-onset seizures.Methods:SP848 was a global multicenter single-arm study involving 60 Chinese children with partial-onset seizures with the age of 4-17 years who were managed by Lacosamide add-on therapy at seven hospitals across China from April 2018 to May 2019.After treatment with at least two kinds of anti-seizure medications simultaneously or sequentially, partial seizures were still poorly controlled and Lacosamide oral solution (syrup) or tablets were added.The minimum initial oral dose was 2 mg/(kg·d), and the maximum allowable dose was 12 mg/(kg·d)or 600 mg/d during the study period.The dose was adjusted according to the tolerance and seizure control level of partial-onset seizures children.Seizure frequency and the median percentage change in partial-onset seizures per 28 days from baseline to the final visit were recorded, including 50% responder rate and 75% responder rate.Results:A total of 60 Chinese children with the mean age of 9.18 (4.00-15.40) years were included in this interim analysis, involving 39 males and 21 females.The mean course of epilepsy was 5.04 (0.50-15.20) years.A total of 43 patients (71.7%) still have been treated.One patient (1.7%) has completed the 6-12 months of follow-up, and 14 patients (23.3%) have completed the follow-up for less than 6 months.The median change in the frequency of partial seizures every 28 days from baseline to the last visit was -2.91, with its median percentage as -25.46%, and the proportions of ≥50%, while ≥75% responder rate were 40.0% and 28.3%, respectively.A total of 52 patients (86.7%) had 265 treatment emergent adverse events (TEAE), 11 patients (18.3%) had 19 serious TEAE, 37 patients (61.7%) had 127 drug-related TEAE, and 11 patients (18.3%) had 16 TEAE leading to the discontinuation of the trial.The most common TEAE were upper respiratory tract infections (20 cases, 33.3%), followed by drowsiness (16 cases, 26.7%), dizziness (15 cases, 25.0%) and vomiting (13 cases, 21.7%). There were no abnormal changes in the electrocardiographic findings during the treatment.Conclusions:For Chinese patients with partial seizures who are older than the age of 4 years and poorly controlled by other drugs, Lacosamide is effective and well tolerated as an add-on therapy drug.The safety characteristics are consistent with those reported in children and adults.No new safety concerns are identified.

Objective:To investigate the clinical features and treatment effect of children with central nervous system demyelinating diseases and seropositivity to myelin-oligodendrocyte glycoprotein (MOG) antibody.Methods:The clinical characteristics of 28 had seropositivity to MOG among 115 children with central nervous system demyelinating diseases and who were hospitalized at Department of Neurology, Children′s Hospital of Zhejiang University School of Medicine from March 2017 to February 2019 were retrospectively analyzed.Results:Twenty-eight patients were included in this study, including 10 males and 18 females, with the ratio of male/female of 1.00∶1.80, and the median age of 7 years and 9 months.The clinical manifestations were diverse, including encephalopathy symptoms such as hea-dache, vomiting, and drowsiness (13/28 cases), vision loss (7/28 cases), spinal symptoms (6/28 cases), cerebellar symptoms such as ataxia, slurred speech (4/28 cases), convulsions (2/28 cases), and cranial nerve symptoms (1/28 cases). Among 24 cases who underwent CSF detection, 10 patients (41.7%) had slightly increased white blood cells, 2 patients (8.3%) had elevated protein, 6 patients (25.0%) had positive MOG antibody, and CSF-restricted oligoclonal band was negative in all 24 patients.Twenty-five cases (89.3%) showed brain magnetic resonance imaging (MRI) abnormalities, including cerebral white matter (20/28 cases), cerebellum (10/28 cases), cerebral gray matter (9/28 cases), thalamus/basal ganglia (6/28 cases), brainstem (6/28 cases), optic nerve (5/28 cases), and corpus callosum (4/28 cases). Of the 28 cases, 13 patients had spinal cord involvement, involving cervical spinal cord in 10 cases, thoracic cord in 9 cases and lumbar spinal cord in 5 cases; besides, 8 cases of them had long segmental spinal cord lesions with ≥ 3 segments.Fourteen patients received the visual evoked potentials′ examination, and the subclinical visual impairment was found in 2 of them with unobstructed clinical performance.All patients underwent high-dose Methylprednisolone therapy.The clinical symptoms of 16 patients who were treated with Gamma globulin were relieved in the acute phase.Seven patients had recurrence during the follow-up period, with the recurrence rate of 25.0%.Relapsed patients re-treated with high-dose Methylprednisolone therapy combined with Gamma globulin, clinical symptoms could be alleviated.Conclusion:The main clinical phenotype of children with central nervous system demyelinating diseases and seropositivity to MOG is acute disseminated encephalomyelitis.The spinal cord lesions are mainly involving cervical and thoracic segments.The current treatments of this disease include glucocorticoid and Gamma globulin, which have significant effect, but the disease is easy to relapse.The re-use of glucocorticoid and Gamma globulin after relapse is still effective.

The clinical data of a case with late-onset isolated sulfite oxidase deficiency(ISOD)admitted in the Department of Neurology, Children′s Hospital, Zhejiang University School of Medicine in July 2021 were retrospectively analyzed.Fifteen previously published cases of late-onset ISOD were also reviewed.The patient was a girl, who was hospitalized because of " motor regression with mental retardation for 5 days" at 1 year old.The manifestations of the patient were extrapyramidal symptoms, regression of motor development and seizures.The level of urinary sulfites in the patient was increased.Magnetic resonance imaging (MRI) features were bilateral pallidus and substantia nigra.Gene sequencing suggested a pure missense mutation of the sulfite oxidase( SUOX) gene c. 650(exon5)G>A(p.Arg217Gln). In 16 cases of late-onset ISOD, the median age at onset and diagnosis was 10.5 months and 34.0 months, respectively.The common clinical manifestations were hypotonia (13 cases), seizures (10 cases), movement disorders (9 cases), and ectopia lentis (6 cases). The most common brain MRI feature was pallidus changes (11 cases), followed by lesions of substantia nigra (5 cases), and cerebral atrophy (4 cases). Fourteen cases of late-onset ISOD showed a positive urinary sulfite test.The missense mutation of the SUOX gene was found in 9 cases.It suggested that brain MRI involvement of bilateral pallidus, high excretion of urine sulfites and the missense mutation of the SUOX gene were important diagnostic clues for late-onset ISOD.

A retrospective analysis was made on the clinical data and gene mutation characteristics of 2 children admitted to the Children′s Hospital of Zhejiang University School of Medicine for epilepsy without periventricular nodules caused by the ARF1 gene mutation from August 2023 to February 2024, and relevant literature was reviewed.Both patients presented with seizures and psychomotor retardation, and 1 of them was diagnosed with West syndrome.Whole exome sequencing confirmed that the 2 patients carried a missense mutation in the ARF1 gene (c.55C>A, p.R19S).Brain magnetic resonance imaging (MRI) of 2 patients revealed no obvious abnormalities.A summary analysis of 5 cases of ARF1 gene mutations reported in three foreign literatures showed that patients with ARF1 gene mutations usually presented with seizures, developmental delay, hypotonia, mental retardation, and motor stereotypies.MRI showed periventricular nodular heterotopia, corpus callosum dysplasia, subcortical white matter abnormalities, and delayed myelination.This study found for the first time that ARF1-related disorders can occur without significant brain structural malformations, indicating that there are inconsistencies in neuroimaging findings, adding valuable phenotypic information to this gene.The differences in imaging findings may be the result of genetic background or variation in ARF1-interacting proteins, or may be caused by altered regulatory mechanisms of protein activity.

Objective:To summarize the best evidence of thirst management in peripheral surgical patients in China, and to provide theoretical basis for clinical thirst management.Methods:According to the PIPOST model, research questions were raised. According to the "6S" model, literature published by various guide websites, evidence-based databases, original research databases and professional association websites at home and abroad from database establishment to January 30, 2022 were systematically retrieved. Two researchers independently evaluated the quality of the literature and extracted and integrated the evidence of the literature that met the quality standards. The research team graded the evidence and determined the recommendation level.Results:A total of 15 literatures were selected, including 2 systematic reviews, 3 clinical decisions and 10 randomized controlled trials (RCTS) . A total of 23 evidences were sorted out, including 8 aspects such as drug factors affecting thirst, thirst assessment tools, preoperative thirst intervention strategy, postoperative safe drinking water assessment, postoperative thirst intervention strategy, nursing observation, health education and precautions.Conclusions:In the absence of uniform standards for perioperative thirst management, the evidence summarized in this study can provide evidence-based evidence for clinical nursing work.
