As the development of technology in Neonatal Intensive Care Unit,the neurology outcome of premature has become a critical issue for their future life quality.Early electroencephalogram (EEG) test is a noninvasive and convenient method to monitor brain function.Nowadays,EEG monitoring has been used to evaluate the maturity of background activity,to detect subclinical seizures and to predict future neurological outcomes.The guideline of American clinical neurophysiology society in 2011,and the guideline of French clinical neurophysiology society in 2015 have made recommendations for the indication,timing and duration of EEG monitoring.Interpret EEG needs both skill and experience,it is hard for clinicians to master the skill in a short time.Hence,despite the advantages of EEG monitoring,the application of EEG among premature is limited.The amplitude-integrated EEG and other quantitative EEG monitoring method have become the latest research hotspot for evaluation of preterm brain function.In order to improve the recognition of EEG in the area of preterm neurologic evaluation,now the latest researches are reviewed.

Objective To investigate the effect of naloxone on c-fos expression in hippocampus induced by repeated febrile seizures(FS).Methods Warm water induced rat FS model was developed in this study. Each rat was induced 7 febrile seizures with the interval of one day. Naloxone-treated rats and FS control rats received injection of naloxone(1 mg/kg,2 mg/kg) or saline once FS occurrence every 2 day respectively. All rats were sacrificed 24 hours after the last seizure. In hippocampus, c-fos expression distribution and semi-quantitative analysis was determined by immuhischemical staining measure and western-blotting respectively.Results Compared with FS control group, naloxone treatment could significantly relieve c-fos expression in hippocampus induced by repeated FS, mainly in dentate gyrus(DG) and CA3 region. The comparison between 1 mg/kg and 2 mg/kg naloxone-treated group showed that 2 mg/kg naloxone could reduce c-fos positive expression more significantly.Conclusion Naloxone of proper dosage may significantly alleviate c-fos expression after repeated FS ,which further proved its antiepileptic function and also implied that endogenous opioid may be involved in the regulation of c-fos expression during seizure.

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

Objective To investigate the relationship between the expression of p63, p73 proteins and the development of hemangioma. Methods The immunohistochemical technique and quantitative image analysis were used to detect the expression of p63 and p73 proteins in 40 cases of capillary hemangioma and 20 specimens of normal skin. Results The absorbance value (mean ? SD) of p63 and p73 expression in normal skin tissue, proliferative phase of hemangioma and involuting phase of hemangioma were 0.923 ? 0.191 and 0.953 ? 0.120, 8.271 ? 1.953 and 6.408 ? 2.151, 0.920 ? 0.187 and 1.073 ? 0.516, respectively. The expression of p63 and p73 in proliferative phase of hemangioma was significantly increased as compared with those in involuting phase of hemangioma and normal skin tissue (P 0.05). Conclusions It is suggested that p63 gene is not a tumor suppressor gene but an oncogene in hemangioma and may contribute to the proliferation of endothelial cell and be associated with angiogenesis, and p73 may play an important role in the proliferation of hemangioma.

Objective : To evaluate the effect of low dose naloxone on remote seizure susceptibility after repeated febrile seizures(FS) in developing age. Methods: Warm water induced rat FS model was developed in this study.Forty nine SD rats were randomly divided into two groups: normal control group( n =10) and hyperthermic seizure group( n =39).The latter was further divided into FS control group( n =13) and naloxone treated group( n =26). The dose of naloxone was different in the two naloxone treated groups(13/each group). One group dose was 1 mg/kg, and the other 2 mg/kg. Each rat of hyperthermic seizure groups was induced to have 7 febrile seizures at the interval of 1 day. The rats were weighed and injected intraperitoneally with naloxone once the FS occurred in naloxone treated group, while the rats of other groups were injected with 0.9% sodium chloride. After the seventh stimulation, all rats were left un stimulated for 2 months, then re stimulated. Re stimulated seizureincidence rate, seizure duration and seizure grade in different groups were observed and compared with each other. Hippocampal mossy fiber sprouting was detected by Timm stain. Results: In naloxone treated group, the rats'seizure duration and seizure grade [(5.66?2.78) min,(2.97? 1.18)] significantly decreased ( t =5.035, P

The association of coagulation function with progressive proteinuria in type 2 diabetic patients was retrospectively analyzed.With increasing microalbuminuria,fibrinogen level was increased significantly.Fibrinogen was an independent risk factor of microalbuminuria. In patients as the early-stage diabetic nephropathy (DN)progressed to clinical-stage DN,the baseline level of fibrinogen was also increased [ ( 3.5 ± 0.9 vs 3.0 ± 0.6 ) g/L,P＜0.05 ].Fibrinogen may serve as a useful predictor of progressive proteinuria in type 2 diabetes.

0.05).Compared with control group,significant decrease in positive group was found in the interval from first evacuation of HM to resolution of serum ?-hCG level,(83?18) days versus(126?31)days(P0.05).Conclusions Once HM is diagnosed,evacuation should be performed as soon as possible,the later the evacuation begins,the higher the risks of lung metastasis and chemotherapy are.It is not necessary to worry about lung metastasis before evacuation of HM,the outcome of post- chemotherapy is very good.

Aim To study the effect of Baoxinbao film on endothelin(ET) and nitric oxide(NO) secretion in patients with stable angina pectoris(SAP).Methods 76 patients with SAP were randomly divided into two groups, with 40 cases in the baoxinbao group plastered with baoxinbao film and 36 cases in the isosorbide dinitrate group receiving isosorbide dinitrate. The levels of plasma ET and NO before and after treatment were observed. Results The concentrations of plasma ET were increased and plasma NO reduced significantly in the SAP patients respectively, as compared with those in the control group(all P

Blood lipid level and its associations with insulin resistance were studied in patients with impaired glucose tolerance (IGT).Two hundred and twenty first degree relatives of type 2 diabetes mellitus were grouped into normal glucose tolerance (NGT) and IGT groups according to results of oral glucose tolerance test.Compared with the NGT group,the IGT patients had higher serum levels of total triglyceride (TG),total cholesterol (TC),low density lipoprotein-C (LDL-C) but a lower serum level of high density lipoprotein-C (HDL-C).Homeostasis model of assessment for insulin resistance index (HOMA-IR) and area under curve of insulin (AUCI) also increased.A positive relationship was found between TG and HOMA-IR (or AUCI),but a negative relationship existed between HDL-C and HOMA-IR.In conclusion,abnormal blood lipid metabolism is present in IGT patients and it has a close correlation with insulin resistance.

Objective To evaluate the inhibitory effect of statins on glucose-stimulated insulin secretion (GSIS) of pancreatic islet in rat and to explore its mechanisms. Methods According to the average volume, freshly isolated or 24-hour cultured pancreatic islets were randomly divided into control group( incubated with Kreb-Ringer bicarbonate buffer), the atorvastatin group( incubated with 100 μ mol/L atorvastatin), the fluvastatin group (incubated with 100 μ mol/L fluvastatin)and the pravastatin group (incubated with 100 μ mol/L pravastatin). Stimulated by 2. 8,5. 5,11.1,16. 7 mmol/L and 25.0 mmol/L glucose respectively, the effect of 100 μ mol/L statins on ATP content and GSIS was compared in the four groups. GSIS was performed by the 37℃ bath incubation method and ATP content was measured by chemiluminescence method. Results Incubated with 100 μ mol/L atorvastatin for 30 minutes, in the presence of 16. 7 mmol/L glucose, the ATP content [(9. 54 ± 1. 64) pmol/islet vs ( 12. 33 ± 1.89) pmol/islet] and GSIS (1.60 ± 0. 21 vs 2. 39 ± 0. 30) were significantly reduced in comparison with the control group (P＜0. 05). Cultured with 100 μmol/L fluvastatin for 24 hours, the ATP content [( 10. 24 ±2.01 )pmol/islet vs (12. 31 ±2. 16) pmol/islet] and GSIS (3. 12 ± 0. 32 vs 4. 17 ±0. 37 ) were all significantly decreased at the higher glucose concentration of 16. 7 mmol/L ( P ＜ 0. 05). Conclusion Atorvastatin and fluvastatin may inhibit GSIS by decreasing ATP content in pancreatic islet and the inhibitory effect is related to the strength of its lipophilicity.
