Dravet syndrome is a rare and severe developmental epileptic encephalopathy with variable clinical phenotypes.Dravet syndrome is difficult to diagnose and treat, and related comorbidities have a profound impact on the long-term quality of life of patients and their parents.SCN1A is the main pathogenic gene of Dravet syndrome, and SCN1A mutations are found in more than 85% of the patients.In recent years, with the development of genetic testing technology and the accumulation of cases, the understanding of the characteristics of epileptic seizures, comorbidities and SCN1A gene mutation characteristics in Dravet syndrome has gradually deepened.In addition to conventional antiepileptic drugs, new antiepileptic drugs(cannabidiol, fenfluramine)have also shown good antiepileptic effects and are expected to become second-line drugs for the treatment of Dravet syndrome seizures.This article mainly reviews the research progress of unique clinical phenotype, SCN1A gene mutation characteristics and new antiepileptic drugs of Dravet syndrome, in order to deepen clinicians′ understanding of the disease.

Abnormal expression and dysfunction of voltage-gated Calcium channels (VGCCs) can give rise to a variety of neurological disorders in children, including epilepsy, migraine and ataxia.In the past, only CACNA1A, CACNA1H, CACNA2D2 and CACNB4 were considered associated with epilepsy in children.In recent years, an increasing number of VGCCs gene associated with epilepsy in children have been found, especially developmental and epileptic encephalopathy genes.This study aims to review the research progress of VGCCs gene mutations associated with epilepsy in children.

Gestational diabetes mellitus (GDM) can lead to adverse pregnancy outcomes and epigenetic changes in offspring due to exposure to a high-glucose intrauterine environment, resulting in related short- and long-term complications. MicroRNA (miRNA)-mediated post-transcriptional regulation, a gene expression regulation mechanism that has gained much attention in recent years, may play a role in morbidity in offspring born to mothers with GDM, such as macrosomia, heart development, neurodevelopment, and long-term metabolic diseases. This article reviews the progress of miRNA in GDM and associated complications in the offspring.

Objective To investigate the relationship between the single nucleotide polymorphism of PPARG rs2290449 and the efficacy of combination therapy in sepsis patients with MODS.Methods 382 cases of sepsis with MODS were selected and divided into the effective group and the ineffective group,and a case-control study was conducted.PCR-RFLP and Sequenom MassARRAY were used to detect the genotype and allele frequencies of the loci.Unconditional Logistic regression was used to calculate odds ratio(OR)and 95％confidence interval(CI)to evaluate the efficacy of combination therapy for sepsis with MODS in patients with different genotypes.Re-sults There were G and A alleles in PPARG rs2290449 locus,GG、GA and AA genotype.Non-conditional Logis-tic regression analysis showed that compared with the GG genotype group,the GA genotype group had a significant correlation with the efficacy of combination therapy for sepsis with MODS(OR=0.449,95％CI=0.280-0.722,P=0.001).In the dominant model,there was a significant correlation between the GA+AA genotype and the effi-cacy of combination therapy compared with the GG genotype(OR=2.104,95％CI=1.332-3.321,P=0.001).After adjusting for confounding factors,unconditional Logistic regression analysis showed that compared with the GG genotype,the GA+AA genotype was significantly correlated with the efficacy of combination therapy in sepsis pa-tients with MODS(OR=2.307,95％CI=1.438-3.701,P=0.001).Stratified analysis showed that compared with the population carrying GG genotype,the population carrying GA+AA genotype was significantly correlated with the efficacy of combination therapy in sepsis with MODS in the stratified analysis of age,gender and ethnicity.Conclusion PPARG rs2290449 single nucleotide polymorphism is significantly correlated with the efficacy of com-bination therapy in sepsis patients with MODS in Yanbian area.

Objective To assess and summary the guideline best evidence on malnutrition risk screening in adult inpatients so as to provide a reference for malnutrition risk screening of adult inpatients. MethodsGuidelines on malnutrition risk screening in adult inpatients were systematically retrieved in nutrition association official website, guideline website and database and were screened. All of the guidelines were assessed by 4 trained researchers with the Appraisal of Guidelines for Research and Evaluation (AGREEⅡ). Guidelines with level C were excluded, and guidelines with level A and B were selected to extract, translate and summary the recommendations. ResultsA total of 213 guidelines were retrieved and 140 were selected after eliminating repetitive guidelines. Finally, 13 guidelines were included after eliminating 128 guidelines by reading titles and abstracts. AGREE Ⅱ evaluation results showed that there were 3 guidelines with level A and 10 guidelines with level B. Analysis and summary showed that a total of 16 items of 3 classes best evidence on malnutrition risk screening in adult inpatients were selected including screening qualification, population, time and tools. ConclusionsIn this study, guidelines best evidence on malnutrition risk screening in adult inpatients provides a credible reference for clinical practice. Population with high risk of malnutrition should be assessed in comprehensive nutrition and should be treated in nutritional department when necessary.

Background Precise prevention and control refers to the means of dividing a large area into several small areas, clarifying the disease information in each small area, and carrying out prevention and control program in the small areas accordingly. It is an important starting point for a comprehensive prevention and control program targeting liver cancer, which can make the prevention and control of liver cancer more accurate and efficient. At present, most of the mainstream research on liver cancer prevention and control at home and abroad is only on the provincial and municipal level, which is difficult to meet the requirements of precise prevention and control. Objective Taking S County, a typical county in Central China as an example, to explore the temporal and spatial distribution of liver cancer and environmental health risks at the township scale, so as to provide scientific reference for developing precise prevention and control program. Methods Based on the liver cancer data in the tumor registry data and related environmental variables of S County from 2009 to 2018, a spatiotemporal analysis was carried out by using geographic information system mapping, global Moran index analysis, and cold and hot spot detection. The correlations between liver cancer and various environmental factors [fine particulate matter (PM_2.5), aerosol optical depth (AOD), temperature, precipitation, proportion of cultivated land, normalized difference vegetation index (NDVI), population density, and per capita gross domestic product (GDP)] in S County were preliminarily evaluated by using geodetectors. The environmental factors and their cumulative exposure years that were closely related to the liver cancer in S County were investigated by random forest model. On this basis, the towns were categorized based on total, age-specified, and gender-specified incidences of liver cancer through quartile ranking, and precise prevention and control suggestions were proposed. Results ZD, HD and BYJ had the highest incidence rates of liver cancer, and the average annual incidence rate was 628/10⁵, 58.28/10⁵, and 40.21/ 10⁵, respectively. In addition to the above three townships, LW was a high incidence area of liver cancer in male population and people under the age of 60 years, whose average annual incidence rate was 50.47/10⁵ and 10.59/10⁵, respectively, while LianC was a high incidence area of liver cancer in female population and people aged 60 years and above, whose average annual incidence was 23.39/10⁵ and 131.10/10⁵ respectively. The incidence of liver cancer was closely related to population density, GDP per capita, NDVI, and AOD, and their importance indicators were 0.92, 0.50, 0.43, and 0.36, respectively. The average time interval between continuous exposure to dangerous environmental factors and the diagnosis of liver cancer was 10 years. Conclusion HD, ZD, and BYJ of S County should vigorously carry out liver cancer screening, diagnosis, and treatment in the follow-up prevention and control, while HD and LW should continue to implement environmental protection. LW needs to strengthen the prevention and treatment of liver cancer in male population and population under 60 years old. LianC needs to strengthen the prevention and control of liver cancer in female population and people of and over 60 years of age. The towns around HD need to prevent the sudden outbreak of liver cancer. In addition, it is also necessary to strengthen the willingness of people in the county, especially those of and over 60 years old, to participate in liver cancer screening. This study provides important reference for the analysis of environmental health effects at a fine scale and for the prevention and control of liver cancer and environmental protection in different populations.
