Objective To study the evaluative values of amplitude integrated electroencephalogram (aEEG) in screening neonatal seizures.Methods The aEEG and video electroencephalogram (VEEG) on 32 patients with seizures hospitalized in Peking University First Hospital was conducted on the same day.The parameters of aEEG including the integrated spectra band,background rhythm and primitive electro signal were analyzed and compared with VEEG.Results Seizures presented clinically by 12 cases were detected by VEEG,and their electric discharges were detected by aEEG.The sensitivity of aEEG was 100%.VEEG showed electric discharges during intermediate stage in twenty cases and thus the seventeen of this group were detected by aEEG with its sensitivity of 87% and 100% in the specificity.The positive and negative predictive values of aEEG were 80% and 100%,respectively.But aEEG could not discriminate the attack stage or intermediate stage electric discharges.The abnormal background activity was detected by VEEG in 13 cases and the sensitivity of aEEG was 100% and the specificity was 83%.The positive and negative predictive value by aEEG were 76% and 100% respectively.The electric discharges of 32 cases were detected by VEEG whenever they were in attack stage or intermediate stage.All electric discharges could be detected through primitive electro signal by aEEG.The electric discharges in 3 cases were not detected by integrated spectra band from aEEG,but were detected by primitive electro signal from aEEG.Conclusions The sensitivity and specificity in the screening of neonatal seizures by aEEG is useful and could be applied clinically as a simple and safe screening method for recognizing neonatal seizures.

OBJECTIVEThis study aimed to investigate the effects of different tooth preparations on the fracture strength and pattern of failure of teeth with severe wedge-shaped defect restored with post and core crowns.

METHODSAccording to whether the teeth above the wedge-shaped defect was removed (represented by B) or not (represented by A), the ferrule next to the wedge-shaped defect was prepared (represented by D) or not (represented by C), the cast post-and-core was chosen (represented by E) or glass-fiber post and resin core was chosen (represented by F). A total of 64 human mandibular premolar teeth were randomly divided into 8 groups: A1-1 (A + C + E), A1-2 (A + C + F), A2-1 (A + D + E), A2-2 (A + D + F), B1-1 (B + C + E), B1-2 (B + C + F), B2-1 (B + D + E), B2-2 (B + D + F), each group 8 teeth. All the teeth were prepared and restored accordingly and then mounted on an electronic pressure universal testing machine. The maximum fracture strength and the patterns of failure were recorded.

RESULTS1) The fracture strength of Group A1-1 > that of Group B1-1, Group A1-2 > Group B1-2, Group B2-1 > Group B1-1, and Group B2-1 > Group B2-2 with significant differences (P < 0.05). 2) The patterns of repairable fracture in Group A1-2 and B1-2 were both 37.5%, and that of the other groups were 0. Furthermore, the difference was significant, and Group A1-2 and B1-2 were higher than other groups.

CONCLUSIONThe maintenance of the overhang above the severe wedge-shaped defect aid in the improvement of the fracture strength of the tooth restored with post and core crown. The ferrule of the wedge-shaped defect is not recommended to be prepared. Furthermore, the glass-fiber post and resin core is favorable for the re-repair of the teeth than the cast post and core.

This article was aimed to study the optimum extraction process of paeonol. The extraction yield of paeonol was taken as investigation index. And the best extraction process was screened by orthogonal experimental design. The results showed that the optimum condition of extraction process was to soak coarse powder of Paeonia suffruti-cosa into 15-fold water for 0.5 h, and then the distillation lasted for 2.5 h. The distillate was collected and cooled to room temperature. The crystallization lasted for 24 h at 4℃, and then filtered and dried for 48 h at room tempera-ture. It was concluded that the selected technology was stable, reasonable and feasible. The extraction yield of paeonol is over 80%.

This article was aimed to study effect of D-ribose on the high-energy phosphate metabolism of skeletal muscle tissues of tired mice. The model was made by burden swimming. And then, the mice were divided into four groups, which were the model group, D-ribose group, caffeine group, and D-ribose with caffeine group). Intragastric administrations of drugs were given to all mice in four groups, three times per day. And all mice continued to swim for three days. The time of swimming was recorded. Gastrocnemius of mice were removed after swimming or 3 days later to measure the concentration of ATP, ADP, AMP and IMP with the HPLC. The results showed that compared with the control group, the time of burden s wimming was significantly prolonged for mice in the D-ribose group and the D-ribose with caffeine group. After three-day recovery, the concentration of ATP, AMP and IMP of gastrocnemius in the D-ribose group and the D-ribose with caffeine group mice was significantly increased. There was no significant difference in the caffeine group mice. It was concluded that D-ribose is involved in the high-energy phosphate metabolism of skeletal muscle tissues of tired mice . D-ribose promotes the recovery of ATP concentration in the gastrocnemius of tired mice, and prolongs the time of burden swimming. Therefore, it has a certain anti-fatigue effect .
