Background: This study aimed to estimate temporal trends in metabolically unhealthy obesity (MUO) among United States (US) adults by age, sex, race/ethnicity, and income from 1999 to 2018. Methods: We included 17,230 non-pregnant adults from a nationally representative cross-sectional study, the National Health and Nutrition Examination Survey (NHANES). MUO was defined as body mass index ≥30 kg/m2 with any metabolic disorders in blood pressure, blood glucose, and blood lipids. The age-adjusted percentage of MUO was calculated, and linear regression models estimated trends in MUO. Results: The weighted mean age of adults was 47.28 years; 51.02% were male, 74.64% were non-Hispanic White. The age-adjusted percentage of MUO continuously increased in adults across all subgroups during 1999–2018, although with different magnitudes (all P<0.05 for linear trend). Adults aged 45 to 64 years consistently had higher percentages of MUO from 1999–2000 (34.25%; 95% confidence interval [CI], 25.85% to 42.66%) to 2017–2018 (42.03%; 95% CI, 35.09% to 48.97%) than the other two age subgroups (P<0.05 for group differences). The age-adjusted percentage of MUO was the highest among non-Hispanic Blacks while the lowest among non-Hispanic Whites in most cycles. Adults with high-income levels generally had lower MUO percentages from 1999–2000 (22.63%; 95% CI, 17.00% to 28.26%) to 2017–2018 (32.36%; 95% CI, 23.87% to 40.85%) compared with the other two subgroups. Conclusion This study detected a continuous linear increasing trend in MUO among US adults from 1999 to 2018. The persistence of disparities by age, race/ethnicity, and income is a cause for concern. This calls for implementing evidence-based, structural, and effective MUO prevention programs.

Objective To monitor heart-related parameters of hypoxic pulmonary hypertension(PH)mouse models induced by hypoxia alone and hypoxia combined with vascular endothelial growth factor receptor inhibitor SU5416 using echocardiography,and to construct the prediction equation of right ventricular systolic pressure(RVSP).Twenty-four C57BL/6J male mice were randomly divided into simple hypoxia group(group A),hypoxia combined with SU5416 group(group B),control group(group C),each group 8 mice.Hypoxic PH models were constructed with hypoxia alone and hypoxia combined with SU5416 in group A and group B,respectively.Echocardiography was performed before and during modeling(2,3,4 weeks after interventions),and the relevant parameters were obtained.RVSP was measured using right heart catheterization after the last echocardiography.The changes of ultrasonic parameters were observed,the correlations of ultrasonic parameters 4 weeks after intervention with RVSP were observed,and linear equations for predicting RVSP were established.Results With time going,during modeling,pulmonary artery diameter(PAD),PAD/aorta diameter(AOD)and right ventricle anterior wall thickness(RVAWT)increased,while heart rate,pulmonary artery acceleration time(PAAT),PAAT/pulmonary artery ejection time(PAET)and tricuspid annular plane systolic excursion(TAPSE)decreased in group A and B(all P＜0.05).Three and 4 weeks after interventions,PAET,PAAT/PAET and TAPSE in group B decreased compared with those in group A(all P＜0.05).Four weeks after interventions,RVSP in group A and B were highly correlated with PAD/AOD,RVAWT,PAAT,PAAT/PAET and TAPSE(all P＜0.05).The linear regression equations of PAAT/PAET and TAPSE for predicting RVSP in simple hypoxic PH mice models included RVSP=-161.7 ×(PAAT/PAET)+63.85,as well as RVSP=-36.53 ×TAPSE+71.55,while of predicting RVSP in hypoxia combined with VEGFR-2 inhibitor PH mouse models were as follows:RVSP=-266.4 ×(PAAT/PAET)+91.59,RVSP=-69.14 × TAPSE+116.5.Conclusion Four weeks after inerventions,the phenotypes of hypoxic PH mouse models induced by hypoxia alone and hypoxia combined with SU5416 became obvious.Prediction equations of RVSP established based on PAAT/PAET and TAPSE obtained with echocardiography could provide references for relevant research.

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 features, imaging findings and prognosis of children with overlapping syndrome of myelin oligodendrocyte glycoprotein (MOG) antibody disease and anti-N-methyl-D aspartate receptor (NMDAR) encephalitis (MNOS).Methods:The clinical manifestations, immunological antibodies in blood and cerebrospinal fluid, cranial image, treatment and follow-up of 11 patients diagnosed as MNOS in the Department of Neurology, Beijing Children′s Hospital from January 2011 to April 2019 were analyzed retrospectively.Results:A total of 11 patients, including 4 males and 7 females were analyzed, the age of onset was (10.4±2.3) years. A total of 29 episodes occurred in 11 children. At the last follow-up, 8 cases showed relapsed remission course, the interval of recurrence was 3 to 60 months. The onset symptoms of 11 patients included convulsions (10 cases), lethargy (6 cases), psychosis (6 cases). Among 29 episodes, the common symptoms were convulsions (16 episodes), psychosis (13 episodes),and lethargy (10 episodes). According to the diagnostic criteria of anti-NMDAR encephalitis and MOG-antibody disease, 29 episodes were divided into three phenotypes, including anti-NMDAR encephalitis(4 episodes), MOG-antibody diseases (10 episodes) and overlapping types (15 episodes).Twenty-seven times of acute stage cranial magnetic resonance imaging (MRI) were available, common lesions included cortical focus (22 times), subcortical white matter (7 times), brainstem (9 times). All patients were sensitive to first-line immunotherapy. Eight patients had recurrence during glucocorticoid reduction, 6 of them were treated with additional second-line immunosuppressive therapy, including cyclophosphamide (1 case) and mycophenolate mofetil (5 cases). The follow-up time of patients were 5-99 months. At the last follow-up, all patients were in remission, the pediatric cerebral performance category (PCPC) score was 1 (10 cases) and 2 (1 cases).Conclusions:MNOS mainly affects older children. In the period of acute episodes, convulsions and psychosis are common. The cranial MRI showed extensive brain involvement and mainly in the cortex. The recurrence rates of MNOS are relatively high, patients are sensitive to first-line immunotherapy. No significant neurological dysfunction was left in the remission stage.

Objective: To investigate the clinical features and diagnostic bases of childhood leukoencephalopathy with cerebral calcifications and cysts (LCC). Methods: The clinical data involving manifestations and laboratory examinations of 4 children with LCC admitted to Beijing Children's Hospital Affiliated to Capital Medical University from 2012 to 2017 were retrospectively summarized. Each patient had a follow-up visit ranging from 4 months to 5 years and 9 months after initial examination. Results: Patients consisted of 2 males and 2 females, whose age of onset was respectively 2 years and 9 months, 6 years and 2 months, 7 years and 10 months, and 5 years and 1 month. The main clinical symptoms of these cases included headache, dizziness, partial seizure and claudication, and two of these cases had insidious onset. Cerebral calcifications and cysts with leukoencephalopathy were detected by neuroimaging in all patients. In addition, multifocal microhemorrhages and calcifications were observed by magnetic susceptibility-weighted imaging (SWI) series in 3 patients. Brain biopsy performed on 1 case disclosed a neuronal reduction in the cerebral cortex, loosening of focal white matter, multifocal lymphocyte infiltration, fresh hemorrhages, and gliosis, as well as angiomatous changes of blood vessels with hyalinized thicken-wall, stenotic or occlusive lumina and calcification deposits. The compound heterozygous mutations of n.*10G>A and n.82A>G in SNORD118 were identified in 1 case by target-capture next-generation sequencing. Sanger sequencing verified that the variant n.*10G>A was a novel mutation and it was of paternal-origin, while the variant n.82A>G was of maternal-origin, which had already been reported to be pathogenic to LCC. Follow-up study had shown continued partial seizure in 1 case and remissive claudication in another, while the remaining 2 cases had a relatively favorable outcome without obvious neurological symptoms at present time. Conclusions The clinical manifestations of LCC are nonspecific, and the onset of the disease tends to be insidious. The triad neuroimaging findings of cerebral calcifications, cysts and leukoencephalopathy are essential to the diagnosis of the disease, and the signals of microhemorrhages revealed by SWI series provide another eloquent reference for the diagnosis. As biopsy is invasive and usually unavailable in the early stage, gene assessment, instead of pathological data, should be the gold standard in the diagnosis of LCC.

Esophageal squamous cell carcinoma (ESCC) is a deadly malignancy with regard to mortality and prognosis, and the 5-year survival rate for all patients diagnosed with ESCC remains poor. A better understanding of the biological mechanisms of ESCC tumorigenesis and progression is of great importance to improve treatment of this disease. In this study, we demonstrated that the glutathione metabolism pathway is highly enriched in ESCC cells compared with normal esophageal epithelial cells in an in vivo mouse model. In addition, treatment with L-buthionine-sulfoximine (BSO) to deplete glutathione decreased the ESCC tumor burden in mice, thus demonstrating the critical role of glutathione metabolism in ESCC progression. BSO treatment also led to decreased cell proliferation and activation of cell apoptosis in ESCC. Finally, BSO treatment blocked NF-κB pathway activation in ESCC. Our study reveals a new pathway that regulates ESCC progression and suggests that inhibition of glutathione metabolism may be a potential strategy for ESCC treatment.
