Abiotic stresses substantially affect the growth and development of plants. Plants have evolved multiple strategies to cope with the environmental stresses, among which transcription factors play an important role in regulating the tolerance to abiotic stresses. Basic leucine zipper transcription factors (bZIP) are one of the largest gene families. The stability and activity of bZIP transcription factors could be regulated by different post-translational modifications (PTMs) in response to various intracellular or extracellular stresses. This paper introduces the structural feature and classification of bZIP transcription factors, followed by summarizing the PTMs of bZIP transcription factors, such as phosphorylation, ubiquitination and small ubiquitin-like modifier (SUMO) modification, in response to abiotic stresses. In addition, future perspectives were prospected, which may facilitate cultivating excellent stress-resistant crop varieties by regulating the PTMs of bZIP transcription factors.

Fetal echocardiography is the first-line imaging tool for diagnosing coarctation of aorta (CoA). Currently, there are some typical ultrasonic features, but no single one can be used for accurate prenatal diagnosis or differential diagnosis of fetal CoA and ultrasonic scoring system remains under investigation in diagnosing or risk classification of CoA. This paper reviews the progress in prenatal ultrasound diagnosis of fetal CoA.

Objective:To summarize the clinical characteristics of SYNGAP1-related epilepsy in children.Methods:Data of 13 patients with SYNGAP1 gene variants diagnosed with epilepsy at Department of Neurology, Beijing Children's Hospital were collected retrospectively from March 2017 to October 2020 and the patients were followed up. The clinical features, electroencephalogram(EEG), brain imaging, gene results and treatment were summarized.Results:Twelve patients were followed up successfully among the 13 patients with SYNGAP1 variants. The last follow-up age was 5 years and 7 months (3 years and 1 month to 9 years).The onset age of seizures was 2 years (4 months to 3 years). Seizure types included eyelid myoclonia with or without absence (9 cases), myoclonic seizure (5 cases), atypical absence (4 cases), suspicious atonic seizures(4 cases),unclassified fall attack (6 cases), and the frequency of seizures varied from several times to more than 100 times per day. Four cases had the mimic phenotype of myoclonic astatic epilepsy. The seizures of 10 cases could be triggered by eating (5 cases), emotion (5 cases), fever (3 cases), voice (2 cases), fatigue (2 cases), etc. Electroencephalography (10 cases) showed interictal generalized or focal epileptiform discharges (9 cases), and atypical aphasia (4 cases), myoclonic seizure (2 cases) and eyelid myoclonic seizure (1 case) were monitored. Of the 12 cases, 9 were added with valproate, all of which were effective (the frequency of seizures reduced>50%). Five cases received combined levetiracetam, in 3 the treatments were effective. To last follow-up, 3 cases were seizure free from 6 months to 1 year and 1 month, but the remaining 7 cases still had seizures, one or several times per day. All 13 cases had developmental retardation (speech ability impaired mostly), 2 cases were severe, 10 cases were moderate, 1 case was mild. The SYNGAP1 gene variants of 13 patients were all de novo, including 12 variants. Among them, 4 were frameshift variants, 4 were nonsense variants, 2 were missense variants and 2 were splice site variants.Conclusions:Patients with SYNGAP1-related epilepsy have an early onset age and many seizure types. The main seizure type is eyelid myoclonia with or without absence, and other seizure types include myoclonic seizure, atypical absence, unclassified fall attack, etc. Valproate is effective in most patients, but seizures in some patients might be intractable. Most patients have developmental delay (mainly moderate and severe), speech ability impaired mostly.

Objective:To summarize the clinical data of patients with acute pandysautonomia (APD) and discuss the treatment and prognosis of them.Methods:A total of 13 patients with APD in the Department of Neurology, Beijing Children′s Hospital, Capital Medical University, from January 2010 to December 2019, were investigated retrospectively.The general data, clinical symptoms, autonomic nerve examination and function test, laboratory examination, treatment and follow-up were collected and analyzed.Results:There were 4 males and 9 females in 13 patients with APD, with an average age was 8 years and 5 months (3 years and 8 months to 12 years and 5 months ). The average course of disease was 94.5 d (14-410 d). The common initial symptoms were gastrointestinal motility disorder (11 cases), dysuria (3 cases), and upright syncope/vertigo (3 cases). During the course of the disease, all the patients manifested with gastrointestinal motility disfunction and dyshidrosis, glands involvement and orthostatic hypotension in 12 cases, abnormal pupil in 9 case and urinary retention in 7 case.Other symptoms included fatigue in 9 cases, emotional disorder in 4 cases, limb weakness in 2 cases, and sensory disturbance in 2 cases.All the patients were treated with intravenous immunoglobulin (IVIG), and 3 cases combined with glucocorticoid.Six patients with severe gastrointestinal symptoms were treated with intravenous nutrition; 4 patients were fed with jejunum, 3 cases of whom returned to normal diet within 1-12 months, and 1 patient was followed up for 5 years and 2 months.Hyponatremia was found in 7 cases, which recovered in 2-30 d. Nine cases were followed up for 1 month to 9 years.Seven cases were normal in daily work and study, with satisfactory nutritional status, stable mood and no relapse.Conclusions:The clinical manifestations of APD are varied.The initial symptoms are gastrointestinal motility disorders, orthostatic hypotension, urinary retention and hyponatremia.Individualized multi-disciplinary comprehensive management for symptoms, especially the comprehensive treatment of gastrointestinal motility disorders, management of postural hypotension, and the urinary system diagnosis and individualized treatment of can shorten the length of hospital stay and improve the prognosis effectively.

Objective:To investigate the clinical and laboratory characteristics of subacute sclerosing panencephalitis (SSPE).Methods:The clinical, laboratory and electroencephalogram (EEG) data of eight patients with SSPE who admitted to the Department of Neurology, Beijing Children's Hospital, Capital Medical University, from May 2014 to February 2019 were retrospectively analyzed and followed up.Results:Four of the patients were male and four were female, who aged from two years and seven months to 13 years and five months with a median onset age of five years and six months. All of the eight cases had disease onset with progressive mental and physical regression, then developed periodic myoclonic seizures at the course of 11 days to 11 months. Video EEG examinations showed persistent generalized periodic complex waves with long interval (3-20 s). The IgG titers of measles virus in blood and cerebrospinal fluid of all cases were significantly increased. There was no significant abnormality in blood/urine metabolism screening nor head magnetic resonance imaging for the first time. Five cases performed head magnetic resonance imaging again, in which two cases with deepening hemispheric sulcus, two cases with cerebral white matter signal abnormalities. Antiepileptic drugs, gamma globulin, adrenocortical hormone and antiviral drugs were used after diagnosis though all were ineffective. All patients presented progressive deterioration. During the follow-up period of three months to two years and seven months, four patients died, of which three patients died at the time of five months, one year and two months, two years and six months after onset respectively, and the other one was unknown.Conclusions:The diagnostic clues of SSPE are progressive mental and physical regression, recurrent myoclonic seizures during period Ⅱ, as well as the extensive periodic complex waves of EEG. It is necessary to detect measles virus IgG antibody in blood and cerebrospinal fluid to make a definite diagnosis. There is no specific treatment for SSPE and its prognosis is very poor.
