Electroencephalogram(EEG) is necessary in diagnosis of status epilepticus (SE),particularly in non-convulsive SE with minor or atypical clinical manifestations.SE is a dynamic process,as seizures continue,in which EEG changed and appeared nonepileptic rhythm discharges.Ictal EEG patterns of SE are non-specific and different types of SE have different EEG features.In this paper,the EEG of different type SE will be summarized.

Objective To study the effects of light on body weight,learning and memory of mice.Methods Fifty mice aged 20 days were randomly assigned to one of the five groups: 200 W light group,100 W light group,60 W light group,40 W light group and normal control group,with 10 in each.They were exposed to different intensities of light 8 hours per day for 1 week.Then we monitored their body weight,examined the mean latency and inaccuracy number in step-down test,and examined the mean latency using a Morris' water maze to observe the effect of light pollution on the mice's learning and memory.Results Compared with the other four groups,there were significant decelerations of body weight increase in 200 W light group.No significant difference in body weight gain was found among the other four groups.The four light-treatment groups had no significant differences from control group in the mean latency,inaccuracy number in step-down test or the mean latency,or the mean crosses to the target in the Morris' water maze.Conclusion Short time high-intensity light can inhibit body weight increase in mice,but short-time light has no effect on the learning and memory of mice.

Objective To study the effects of restructuring tissue inhibitor of matrix metatloproteinase-3 (rhTIMP-3) in combination with cisplatin (DDP) on the growth and apoptosis of A549 lung cancer cell line.Methods We made individual and combined use of different concentrations of rhTIMP-3 and DDP on A549 cells.Methyl thiazoyl terazolium (MTT) colorimetry was used to analyze cell growth inhibition,and flow cytometry technique was used to determine the cell cycle distribution and apoptosis rate.Results rhTIMP-3 and DDP both could inhibit the proliferation of A549 cells.rhTIMP-3 exerted its effect in the time-and concentration-dependent manners while DDP did so in the concentration-dependent manner;both induced the apoptosis of A549 cells.rhTIMP-3 could make the cells stay in S and G2/M phases,and DDP made the cells stay in S phase.The combination of them obviously strengthened the inhibition of A549 cell growth,and had obvious synergy in inducing apoptosis.Conclusion Both rhTIMP-3 and DDP can inhibit the proliferation of A549 cells and induce their apoptosis.The combined use of them not only can increase the inhibition of cell growth but also has synergy in inducing cell apoptosis.

Objective Breast intraductal papillary lesion ( BIPL) has a low incidence but a high rate of malignancy .This study discusses the diagnostic value of conventional ultrasonography ( US) combined with ultrasonic elastography ( UE) for breast papil-lary lesion. Methods We analyzed the preoperative ultrasound data of 48 patients with 63 BIPLs, and classified them according to the characteristics of two-dimensional ultrasound (2DUS) images.Then we compared their color Doppler ultrasound characteristics and UE features with the pathological results . Results Based on the 2DUS findings, the BIPLs were divided into 4 types.The sensitivi-ty, specificity, and accuracy of conventional US +UE in the diagnosis of BIPL were 93.2%, 88.9%, and 90.5%, respectively, markedly higher than those of conventional US (75.6%, 66.7%, and 73.0%), with statistically significant differences in the areas under the curve between the two methods (0.918 vs 0.838, P<0.05). Conclusion Conventional US combined with UE can im-prove the diagnosis of breast intraductal papillary lesion .

Self-assembly refers to the spontaneous process where basic units such as molecules and nanostructured materials form a stable and compact structure. Peptides can self-assemble by non-covalent driving forces to form various morphologies such as nanofibers, nano layered structures, and micelles. Peptide self-assembly technology has become a hot research topic in recent years due to the advantages of definite amino acid sequences, easy synthesis and design of peptides. It has been shown that the self-assembly design of certain peptide drugs or the use of self-assembled peptide materials as carriers for drug delivery can solve the problems such as short half-life, poor water solubility and poor penetration due to physiological barrier. This review summarizes the formation mechanism of self-assembled peptides, self-assembly morphology, influencing factors, self-assembly design methods and major applications in biomedical field, providing a reference for the efficient use of peptides.
