Objective To investigate the clinical features and causes of misdiagnosis of complex partial status epilepticus (CPSE) in the elderly. Methods The clinical data of elderly patients with CPSE admitted in our department between January and December, 2008 with previous misdiagnosis were reviewed. The diagnosis of CPSE was established according to the diagnostic criteria of the International League Against Epilepsy (ILAE). All the patients underwent video-EEG examination, head magnetic resonance imaging (MRI), and routine biochemical examination, and were followed up for at least 3 months. Results Seven female CPSE patients were involved in this analysis including 2 with frontal lobe epilepsy and 5 with temporal lobe epilepsy. The conditions were misdiagnosed as a variety of diseases including Alzheimer's disease, cerebral infarction, coronary heart disease, encephalitis, hysterism, and schizophrenia, and the duration of the misdiagnoses ranged from 2 days to 40 years. Video-EEG showed slow background, continuous interictal discharges or high-voltage slow waves in the temporal or frontal lobe, or ictal discharges of complex partial seizures. After treatment with antiepileptic medications, 3 patients were free of epileptic episodes within 3 months, 3 still remained in complex partial status, and 1 had repeated CPSE. Conclusions Complex symptoms, atypical EEG, co-morbidity and social factors all contribute to misdiagnosis of CPSE in the elderly. Suspected patients should undergo video-EEG examination for a definite diagnosis as early as possible.

Objective To study the clinical features and genetic mechanism of myoclonic-astafic epilepsy (MAE) in infancy. Methods This study was conducted among 10 infants with MAE (including 7 male and 3 female patients) diagnosed between 2006 and 2008 according to the criteria of International League Against Epilepsy (2001). The clinical data including onset age, seizure type, physical signs, EEG, brain maguetic resonance imaging (MRI), effects of anti-epileptic drugs and prognosis were analyzed. The mutations of voltage-gated sodium channel subunit type 1 gene (SCN1A gene) were screened by denaturing high performance liquid chromatography and direct sequencing. Results The 10 MAE cases included 8 sporadic cases and 2 with a family history of febrile seizure and epilepsy. The onset age ranged from 5 months to 39 months, and all the MAE patients had multiple generalized seizure types, including myoclonic-atonic, myoclonic, atonic, tonic-clonic and absence seizures. Two patients had myoclonic status epilepticus, and 7 showed mental retardation. All the patients showed normal findings in MRI. SCN1A gene was screened in 8 of the MAE patients, and no mutation was found. Valproate, clonazepam and levetiracetam were effective in these MAE cases. Conclusion MAE is a rare epilepsy syndrome, whose genetic mechanism is still unclear. Valproate, clonazepam and levetiracetam are effective for MAE, which is associated with poor prognosis.

OBJECTIVETo study the effect and mechanism of mexican tea herb and pilular adina herb (abbreviated to MP) on concrescence of gastric mucosa in experimental gastric ulcer rats by observing the changes of epidermal growth factor (EGF), nitrogen monoxidum (NO) and expression of epidermal growth factor receptor (EGFR).
METHODSThe rat ulcer model was established by 100% glacial acetic injection into the subserosa. The ulcer index (UI) was measured by sliding caliper. The levels of NO and EGF in tissue and serum were measured by the nitrate reductase method and enzyme-linked immunosorbent assay, respectively. The expression of EGFR in the mucosa around the ulcer was detected by the immunohistochemical assay and microimage analysis system.
RESULTS(1) Compared with the model group, UI of MP groups (10, 15 and 20 mg.kg(-1).d(-1)) and ranitidine group was lower (P<0.05 or P<0.01), the levels of NO and EGF in the tissue and serum were higher (P<0.05), the thickness of regenerated mucous membrane increased, and the width loss of lamina muscularis mucosa decreased (all P<0.05). (2) The expression of EGFR is weakly positive in gastric mucosa cells in the normal group, mainly in the cytoplasm and cytomembrane. In the model group, the expression of EGFR was mainly in epithelial cells in cervical part and basilar part of gastric gland around the ulcer margin, and the number of cells with EGFR weakly positive expression was more than that in the normal group. Compared with that in the normal and model groups, the number of cells with EGFR positive in MP groups and ranitidine group increased (all P<0.05), with weakly positive expression.
CONCLUSIONMP can protect gastric mucosa, cure gastric ulcer, restrain the secretion of gastric acid, and boost multiplication, differentiation, migration and repair of the endothelial cell by promoting the secretion of NO and EGF, and increasing the expression of EGFR of gastric mucosa epithelial cells.

Chinese Journal of School Health 2019;40(12):1842-1845
Objective:
To explore the relationship between psychological resilience and cognitive bias towards school violence in grade 3-5 primary school students in Luzhou city, so as to provide scientific basis for prevention and control of school violence in primary school students.
Methods:
Students from grade 3-5 in primary schools in Luzhou were selected through stratified cluster random sampling method and were investigated with questionnaire survey.
Results:
A total of 5 976 valid questionnaires were included, with an average score of psychological resilience (40.08±8.05) and an average score of school violence cognition (62.55±6.38). Multivariate results showed that psychological resilience was an independently associated with school violence perception (OR=1.04, P<0.01). The awareness of campus violence increased with resilience score. In addition, public school (OR=0.45) was associated with low awareness of school violence; senior grades (OR=1.77), girls (OR=1.20), and a greater number of friends(OR=1.37), student cadre(OR=1.37), middle/upper score in class(OR=2.13), no game playing(OR=1.33), no off-campus wandering(OR=1.78), timely parenting (OR=1.45) was associated with high awareness of school violence(P<0.05).
Conclusion
Psychological resilience positively correlates with cognition bias towards school violence. The higher the psychological resilience, the more positive perception of campus violence. Family, school and community-based interventions to enhance the resilience of students, increasing awareness towards school violence and ultimately reducing potential adverse impacts of school violence.

OBJECTIVETo explore the changes of CD(14)(+) monocyte human leucocyte antigen DR (HLA-DR) and their relationship with multiple organ dysfunction syndrome (MODS) in severe sepsis.
METHODSNinety-one patients with a definite diagnosis of severe sepsis in the intensive care unit (ICU) were included. CD(14)(+) monocyte HLA-DR levels were detected by flow cytometry on the first, 4th and 7th days of the study, and Marshall scores and prognosis on day 28 were evaluated.
RESULTSThirty-four patients died within 28 days following the onset with a mortality rate of 37.4%. Persistently lowered levels of HLA-DR were detected and significantly increased Marshall scores were found in the fatal cases at all the time points (P<0.001). In the surviving patients, the levels of HLA-DR were significantly increased (P<0.01) and Marshall scores were gradually decreased (P<0.001). During the observation period, the levels of HLA-DR decreased significantly as the number of dysfunctional organs and Marshall scores increased (P<0.001). The levels of HLA-DR were significantly increased in severe sepsis patients with 2-4 dysfunctional organs and Marshall score of 5-12 (P<0.05 or P<0.001). No changes in HLA-DR levels in severe sepsis patients with 5-6 dysfunctional organs and Marshall scores of 13-22. The levels of HLA-DR showed a significant inverse correlation to Marshall scores (r=-0.368, P<0.001).
CONCLUSIONIn patients with severe sepsis, persistent low CD(14)(+) monocyte HLA-DR levels predicts high mortality. The levels of HLA-DR are significantly correlated to the severity of organ dysfunction.
