Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

OBJECTIVE To study the improvement effects and mechan ism of thalidomide on Alzheimer ’s disease （AD）model of Caenorhabditis elegans . METHODS In this study ，the BR 5270 strain of C. elegans was used as AD model and BR 5271 strain as the control. The effects of thalidomide （0.5，2.0，6.0，15.0 mg/mL）on the motility of BR 5270 strains of C. elegans were studied by the basal slowing response assay ；the effects of thalidomide （0.5，2.0，6.0，15.0 mg/mL）on the survival time of BR 5270 strain of C. elegans were studied by life assay ；the effects of thalidomide （0.5，2.0，6.0 mg/mL）on learning and memory ability of BR 5270 strain of C. elegans were studied by short-term and long-term learning and memory assay. RT-PCR technology was used to study the effects of thalidomide （0.5，2.0，6.0 mg/mL）on mRNA expression of phosphatidylinositol 3-kinase（PI3K）/protein kinase B （Akt）signal pathway related genes （Age-1，Akt-1，Gsk-3）and calpain homologous gene （Clp-1）in BR 5270 strain of C. elegans . RESULTS After the intervention of thalidomide ，oscillation times of BR 5270 strain of C. elegans increased significantly within 30 s （except for 0.5 mg/mL group ），and the 10％ of maximum life span was prolonged significantly （only 0.5 mg/mL group ）；the short-term and long-term learning indexes were improved significantly （only 6.0 mg/mL group ）；mRNA expression of Age-1 and Akt-1（except for 0.5，2.0 mg/mL groups ）were increased significantly ，mRNA expression of Gsk-3（except for 0.5 mg/mL group ） and Clp-1 were decreased （P＜0.05 or P＜0.01）. CONCLUSIONS Thalidomide can ameliorate the dyskinesia of AD model of C. elegans，prolong the lifespan of this strain ，and enhance its learning and memory ability. Its mechanism of action may be related to activation of PI 3K/Akt signaling pathway and inhibition of calpain.

Objective:To summarize the clinical features and prognosis of acute kidney injury in patients with HBV related acute on chronic liver failure (ACLF).Methods:A total of 150 patients who developed acute kidney injury (AKI) in patients with HBV related ACLF from Sep. 2010 to Sep. 2019 were reviewed retrospectively, and the gender, age, laboratory examination, Child-pugh scores, and model for end-stage liver disease (MELD) were collected and the survival of the patients were followed up to analyze the prognosis.Results:Ninety-three percent of the patients were complicated with ascites, 81% with spontaneous peritonitis, 65% with hepatic encephalopathy and 58.7% with pulmonary infection; 60 patients (60.0%) were AKI stage 1, 44 patients (29.3%) were AKI stage 2, 16 patients (10.7%) were AKI stage 3. The patients with hyponatremia had lower albumin ( t=2.571, P=0.011), higher blood urea nitrogen, serum potassium and white blood cell levels than those without hyponatremia ( t=3.184, P=0.002; t=2.069, P=0.040; t=2.251, P=0.026); 74.7% of the patients died within 30 days, and the 90 days survival rate was 16.7%. The 30 days and 90 days mortality of patients with hyponatremia was higher than that of patients without hyponatremia ( χ2=4.11, P=0.044; χ2=3.901, P=0.049 7). Kaplan-Meier analysis revealed that the patients who had abnormal uric acid pre-diagnosis of AKI, hyponatremia when diagnosis of AKI, organ damage other than liver and kidney, metabolic acidosis, upper gastrointestinal tract bleeding, hepatic encephalopathy had a poor survival. Cox regression analysis showed that other organ function damage other than liver and kidney, metabolic acidosis, and the old age, were independent risk factors of death. Conclusions:Most of the AKI patients with HBV related ACLF had ascites and spontaneous bacterial peritonitis when AKI occurred, and AKI stage 1 was common. The mortality of patients with hyponatremia was high, and the risk of death was high in patients with severe organ damage other than liver and kidney, metabolic acidosis and the old age.

OBJECTIVE: To investigate the effect of the combination of atrial fibrillation (AF) ablation and left atrial appendage closure (LAAC) on cardiac function and the success rate of AF ablation. METHODS: We retrospectively analyzed the data of 56 patients with AF undergoing a one-stop procedure for AF ablation and LAAC in our hospital between May, 2015 and May, 2019. Propensity score matching (PSM) at the ratio of 1:1 was used to select 56 control patients undergoing AF ablation at high risk of stroke, for matching with the hybrid procedure group. The perioperative complications, thromboembolic events, recurrence of atrial arrhythmia and cardiac function were compared between the groups. RESULTS: The two groups of patients were comparable for age, gender, BMI, duration and type of AF, concomitant diseases, CHA2DS2-VASc and HAS-BLED scores ( CONCLUSIONS The combination of AF ablation and LAAC is safe but does not improve the success rate of AF ablation. The one-stop procedure can improve cardiac function of the patients, but AF ablation alone can achieve better improvement of cardiac function.
