OBJECTIVE: To investigate the role of anatomical abnormalities in non-sinusitis-related rhinogenous headache and to evaluate effects of nasal endoscopic surgery for non-sinusitis-related rhinogenous headache. METHOD: Sixty-eight patients diagnosed as non-sinusitis-related rhinogenous headache were selected in this study. They were treated with nasal endoscopic surgery after failed long-term medical treatment. Data from this group were analyzed retrospectively. RESULT: Multiple anatomical abnormalities were noted by endoscopy and sinus computed tomographic scans in the 66 patients. These included nasal septum deviation in 46 cases (67.6%), middle turbinate gasfication in 20 cases (29.4%), protruding ethmoid bulla or uncinate processor in 10 cases (14.7%) and abnormal middle turbinate in 8 case (11.8%). Fifty-six (82.4%) patients showed significant improvement after surgery. CONCLUSION Non-sinusitis-related rhinogenous headache can be significantly minimized with individual nasal endoscopic surgery, as long as a precise identification of the etiologic anatomical factor can be made.

Objective To explore the hemodynamic changes in the brains of newborns with intracranial hemorrhage.Methods Totally,61 newborns,born in Anyang Maternal and Child Health Hospital of Henan Province,with intracranial hemorrhage diagnosed by ultrasound in early neonatal period,and 50 healthy newborns,also born in the same hospital from December 1,2010 to June30,2012,were selected.Intracranial hemorrhage newborns were graded according to the severity of hemorrhage and divided into mild (n=45) and severe groups (n =7).The peak systolic flow velocity (Vs),end diastolic velocity (Vd),mean flow velocity (Vm) and resistance index (RI) in the middle cerebral artery (MCA) and anterior cerebral artery (ACA) of brain were measured by Doppler ultrasound.Ttest was applied for statistical analysis.Results Among the 61 neonates with intracranialhemorrhage,12(19.7％) were grade Ⅰ,42(68.9％) were grade Ⅱ,6(9.8％) were grade Ⅲ,and one (1.6％) was grade Ⅳ.The Vs,Vm and Vd of MCA and ACA in the mild and severe intracranial hemorrhage group were significantly lower than those in the control group,the differences were statistically significant [MCA:(55.1±9.1) cm/s,(53.0±6.5) cm/s vs (60.1± 10.3) cm/s;(34.2±6.1) cm/s,(32.5±5.2) cm/s vs (38.2±6.9) cm/s; (17.1±4.8) cm/s,(15.3± 4.0) cm/svs (20.2±5.3) cm/s.ACA:(41.3±11.7) cm/s,(39.4±9.2) cm/s vs (45.3±9.8) cm/s;(25.2±5.8) cm/s,(23.3±4.9) cm/s vs (28.1±5.9) cm/s;(15.0±3.9) cm/s,(13.2±3.1) cm/s vs (15.9±3.8) cm/s,all P＜0.05].But the RI values were significantly higher in the control group,the differences were statistically significant (MCA:0.70 ± 0.10,0.77 ± 0.07 vs 0.62 ± 0.10 ; ACA:0.67±0.06,0.73±0.08 vs 0.61±0.05;all P＜0.05).TheVs,Vm and Vd of MCA and ACA in the severe intracranial hemorrhage group were significantly lower than in the mild hemorrhage group,while the RI values were significantly higher,and the differences were statistically significant (all P＜0.05).Conclusions Newborns with intracranial hemorrhage have significant hemodynamic changes in the brain and more prominent changes could be found in those with severe intracranial hemorrhage.

Objective To understand the current status and the changes in main disability reasons in the elderly with physical disabilities during the past 20 years in China. Methods　The data of the elderly with physical disabilities aged 60 years and over that were from the national sample survey on disability in 1987 and 2006 were analyzed and compared by epidemiology methods. Results　In 2006.the main disability reasons in the elderly with physical disabilities aged 60 and over were disease factors,injury factors,other factors and congenital diseases and eccyliosis.The cause-specific disability prevalences were 5.262%,1.885%,1.000% and 0.200%respectively.Cerebrovaseular diseases showed the highest cause-specific disability prevalence of 2.552% in all the causes.Compared with the national sample survey in 1987,the cause-specific disability prevalences of disease factors and injury factors were obviously increased.The top five disability reasons in the elderly with physical disabilities aged 60 years and over in China were cerebrovascular diseases,arthropathy,miscellaneous traumas,other causes and unknown causes in the national sample survey in 2006;while vascular diseases,other traumas,other causes,unknown causes and pyogenic infection were the top five disability reasons in the national sample survey in 1987.The age-specific top five reasons were basically the same with the total top five disability reasons of the elderly with physical disabilities aged 60 years and over,and also the same relationship between sex-specific top five reasons and Iotal top five disability reasons in 1987 and 2006. Conclusions　Disease factors are the main disability reasons of the elderly with physical disabilities aged 60 years and over,and cerebrovascular diseases have the highest cause specific disability prevalence.The prevention and cure of cerebrovascular diseases,arthropathy and other traumas become the key points to prevent physical disability in the elderly.

BACKGROUND:Maxil ary sinus floor elevation via a lateral window approach is the most effective method of overcoming the shortage of bone mass deficiency in atrophic maxil ary posterior region. Bone transplantation is considered to be a prerequisite for the success of maxil ary sinus floor elevation. Platelet-rich plasma and platelet-rich fibrin have been used to accelerate bone formation, regeneration, and repair. However, few in-depth studies are reported on the effects of concentrated growth factors on new bone formation. OBJECTIVE:To investigate the effects of concentrated growth factors applied in maxil ary sinus floor elevation via a lateral window approach with simultaneous implant placement on repair of bone defects and new bone formation. METHODS:This was a randomized double-blind control ed trial, which was performed at the Hospital of Stomatology, Southwest Medical University, China. Forty patients presenting with loss of maxil ary molars and residual bone height of 2-5 mm in the posterior maxil ary region were included in this study. These patients were randomly assigned to either receive concentrated growth factors, hydroxyapatite and autogenous bone (experimental group, n=20) or hydroxyapatite and autogenous bone (control group, n=20) at bone defect sites. X-ray examination was performed 1, 3 and 6 months after surgery to evaluate bone regeneration and repair as per excel ent and good rate. The thickness of the cortical bone at the defect sites was measured using a dental cone beam CT scanner to reflect bone density. The study protocol had been approved by Ethics Committee of Hospital of Stomatology, Southwest Medical University, China, was performed in strict accordance with the Declaration of Helsinki, and had been registered with ClinicalTrial.gov (identifier NCT03046173). Written informed consent had been obtained from each patient prior to enrol ment. RESULTS AND CONCLUSION:This study was completed in 2016. Study outcomes were obtained as fol ows:X-ray images showed that 3 and 6 months after surgery, bone regeneration around the implant was better in the experimental group than in the control group (P<0.01) and better bone regeneration in the experimental group was observed at 6 months than at 3 months after surgery. At 1, 3 and 6 months after surgery, bone density at bone defect site was significantly greater in the experimental group than in the control group (P<0.01). These results suggest that concentrated growth factors applied in maxil ary sinus floor elevation via a lateral window approach with simultaneous implant placement can promote new bone formation and accelerate synosteosis.

This paper introduces the concept,the research paradigms and the related theory of the attentional blink,and reviews the relevant researches about the attentional blink of the children and adults with ADHD in the last 10 years.Compared to normal subjects,children and adults with ADHD did show more severe AB effect,and adults with ADHD showed more eye movement behavior.In future studies,standardized RSVP paradigm should be set up to provide convenience for the comparison of results of studies,and find out what kind of processing restrictions will affect the characteristics of different age ADHD groups in the time dimension of attention.In addition,ADHD and inhibitory control related closely,consideration should be given to the combination of inhibitory control paradigm and AB paradigm.

Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.

Objective:To explore the prevalence of posttraumatic stress symptoms among preschool children and its related factors after the Ludian earthquake.Methods:A total of 62 children's guardians were visited.They were interviewed with the Posttraumatic Stress Disorder Semi-Structured Interview for Infants and the Young Children and the Child Behavior Checklist-Posttraumatic Stress Disorder scale (CBCL-PTSD) consisted of 15 items from the CBCL.All of the participantsresided in Longtoushan settlement and Longtoushan town (the epicenter).They were randomly visited from west to east in that region.Results:The rate of scored 9 (or more) on the CBCL-PTSD among children was 51.9％ (27/52) in 1-2 months after the earthquake.However,based on the Semi-Structured Interview,the rate of the children's posttraumatic stress symptoms was 26.9 ％ (14/52).The numbers of posttraumatic stress symptoms,intrusion symptoms,avoidance symptoms,hyperarousal symptoms,the new symptoms and the CBCL-PTSD scores were positively correlated (0.30-0.73,P ＜0.05),except the relation between intrusion symptoms and hyperarousal symptoms.The rate of intrusion symptoms was significant higher among those who experienced earthquake than those who didn't (96.2％ vs.60.0％,P ＜0.01).And the rate of intrusion symptoms was also higher among those who was injured during the earthquake than those who wasn't (100％ vs.84.6％,P ＜ 0.05).And the other symptoms were not difference in children under different conditions (P ＞ 0.005).Conclusion:The preschool children who experienced earthquake or were injured suffer more posttraumatic stress symptoms.
