Objective:To explore whether life satisfaction has a mediating effect between child neglect and middle school student’ problematic mobile phone use.Methods:Totally 1 692 middle school students from four middle schools of Xiamen in June 2020 were selected by cluster stratified sampling.The self-rating questionnaire for adolescent problematic mobile phone use (SQAPMPU), child neglect scale (CNS) and quality of life scale for children and adolescents (QLSCA) were used for the survey. SPSS 23.0 software was used for descriptive statistics, correlation analysis, regression analysis and the mediating effect analysis.Results:The scores of CNS, QLSCA and SQAPMPU were (24.45±14.28), (134.44±19.34), (23.20±8.94)respectively.And the detection rate of problematic mobile phone use was 23.6%. There were significant differences in the scores of SQAPMPU scale in different grades, father's education degrees, mother's education degrees and monthly pocket money(all P<0.05). In SQAPMPU, high school students scored significantly higher than junior school students( t=-2.403, P=0.016), adolescents with undergrate education of their father and mother scored the lowest( F=3.411, P=0.017; F=2.729, P=0.043), adolescents with monthly pocket money of "500-1 000" and "1 000-2 000" scored significantly higher than those with monthly pocket money of "under 500". The total scores and sub scores of child neglect were significantly positively correlated with the total scores and sub scores of problematic mobile phone use ( r=0.177-0.360, all P<0.05). The total scores and sub scores of life satisfaction were significantly negative correlated with the total scores and sub scores of problematic mobile phone use ( r==-0.508--0.250, all P<0.05). Child neglect had a positive predictive effect on problematic mobile phone use ( t=15.598, R2=0.130, P<0.05), but had a negative predictive effect on life satisfaction ( t=-27.798, R2=0.321, P<0.05). There were the part intermediary role of life satisfaction between child neglect and problematic mobile phone use( t=-13.937, R2=0.222, P<0.05), and the mediating effect accounted for 58.29% of the total effect. Conclusion:The neglected experience in childhood of adolescents not only can directly affect problematic mobile phone use, but also can affect the problematic mobile phone use by affecting life satisfaction.

Objective:To investigate the clinical and imaging features of spontaneous convexal subarachnoid hemorrhage (cSAH) with acute cerebral infarction.Methods:Nine patients with cSAH complicated with acute cerebral infarction, admitted to our hospital from January 2018 to October 2021, were selected. The clinical data and efficacy of these patients were retrospectively analyzed.Results:The time from cSAH to the onset of acute cerebral infarction was 5-144 h, with median time of 2 d. The most common bleeding site of cSAH was the parietal lobe ( n=6); cSAH in the ipsilateral side of acute cerebral infarction was noted in 4 patients. Six patients had middle cerebral artery stenosis or occlusion, and 2 patients had anterior cerebral artery stenosis or occlusion. Hypertension ( n=7) was the most common primary disease; 7 patients were treated with antiplatelet drugs, anticoagulants and/or stents. The follow-up at 3 months after cSAH showed that 6 patients had good prognosis and one had poor prognosis. Conclusions:The cSAH often occurs 2 d after acute cerebral infarction; intracranial artery stenosis or occlusion may be the main cause of the disease. In patients complicated with cSAH, active antiplatelet, anticoagulation and/or stent therapy do not increase the risk of bleeding, and the prognosis is good.

Objective To investigate the clinical features,etiology,diagnosis and treatment of acute auditory agnosia.Methods We studied the clinical manifestation,diagnosis and treatment of acute auditory agnosia in a patient in our hospital.Results A 28 year oldyoung woman visited our department because she suffered from the tinnitus for 7 days and she could not distinguish the semantics for 1 day.There were no other abnormal symptoms in the central and peripheral nervous system on admission.Audiological testing showed normal,language testing showed that the speech discrimination score was zero.MRI showed extensive damage to temporal lope.MR spectroscopy revealed increased lactate and reduced N-acetyl aspartate.Acute auditory agnosia resulted from mitochondrial myopathy was considered.After symptomatic treatment,the symptoms were significantly improved.Molecular genetics examination showed the A3243G mtDNA mutation,further confirmed the diagnosis of mitochondrial encephalomyopathy with lactic acidosis and stroke like episodes (MELAS) syndrome.Conclusion Acute auditory agnosia and acute tinnitus can be the first symptoms in MELAS,thus,MELAS should be suspected in patients with acute auditory agnosia,acute tinnitus,sudden hearing loss in children and youth.Imaging examination plays an important role in the etiological diagnosis of acute auditory agnosia.
