RESUMEN
Objective:The purpose of this study was to analyze the expression profile of miRNAs in children with autism spectrum disorders (ASD), and to discuss the clinical significance of differentially expressed miRNAs.Methods:MiRNA microarray was used to analyze the expression of miRNA in peripheral blood of 3 pairs of ASD patients-healthy controls; 17 pairs of ASD patients-healthy controls were used to verify the differentially expressed miRNA; Receiver operating characteristic (ROC) curve was used to analyze the differential expression the value of miRNA in the diagnosis of ASD.Results:A total of 32 differentially expressed genes were screened by 3 pairs of miRNA microarray including 12 up-regulated miRNAs and 20 down-regulated miRNAs. miRNA verification of 20 differentially expressed miRNAs showed miR-15a-5p, miR-27a-3p , miR-142-3p and miR-142-5p were significantly down-regulated in children with ASD, with statistically significant difference (all P<0.05). ROC curve analysis showed that the area under the curve (AUC) of the above four miRNAs diagnosing ASD were all greater than 0.70, with sensitivities 94.12%, 100%, 100%, and 82.35%, respectively. Conclusions:The expression of miR-142-3p, miR-27a-3p/miR-15a-5p, and miR-142-5p is down-regulated in the peripheral blood of ASD patients, and has the potential as biomarkers for early screening of ASD.
RESUMEN
Liver cirrhosis in China can be caused by many causes of which the most important one is chronic viral hepatitis. Hemorrhage and ascites were the main manifestations of decompensated liver cirrhosis, and the main cause of hemorrhage is viral hepatitis. The pathological basis of hemorrhage is portal hypertension and its secondary pathophysiological changes. Additionally, the deficiency of coagulation factors and the imbalance of coagulation and fibrinolysis both of which caused by the hypofunction of liver are also important reasons. This article reviews the mechanism of hemorrhage in decompensated liver cirrhosis in order to provide help for further research.

Objective To investigate the characteristics of the adverse drug reaction (ADR) in the traditional Chinese medicine (TCM) treatment followed the "COVID-19 Diagnosis and Treatment Program (trial version 7)" during the medical observation period, and to provide a guideline for rational clinical drug use. Methods 9 TCM induced ADR were collected from CNKI, Wanfang database and PubMed. Statistical analysis was conducted on gender, age, occurrence time, involved system/organ, treatment, outcome and relevance evaluation. Results 61 literatures were collected according to the inclusion and exclusion criteria with 70 cases and 5 TCM prescriptions. There was no significant bias in gender. The age span was large. Most ADR occurred within 1 day after administration. The involved systems/organs are extensive, mainly on the skin and its accessories. The most common therapeutic drugs were antihistamines and steroids, and other medications are mainly for symptom treatment. The turnaround time was 1 h in most cases (47%). Conclusions During the observation period, the incident population was widely distributed and there was no obvious characteristics. Medication monitoring should be reinforced to reduce the ADR incidence.
RESUMEN
Hand-foot-and-mouth disease (HFMD) is a common infectious disease caused by human enterovirus (EVs). It is more common in children under 5 years of age.The clinical symptoms are mainly rash and herpes in the hands, feet, mouth and other parts.Some serious cases may suffer from serious complications in nervous system, respiratory system or circulatory system.Since 1998, HFMD has been mainly caused by enterovirus 71 and coxsackievirus A16 (CV-A16). In the past 10 years, coxsackievirus A6(CV-A6) has gradually replaced EV-71 and CV-A16, and become a main pathogen of HFMD.Many literatures have shown that CV-A6 often causes atypical HFMD, which is mainly characterized by a wider and more serious rash and desquamation, and even onychomadesis.At present, there are some reports on the prevalence and detection methods of HFMD caused by CV-A6.The paper reviewed on CV-A6 related etiology, epidemiology, clinical manifestations and treatment of HFMD.
