Objective A retrospective study was conducted to evaluate the clinical significance of Video EEG monitoring in the diagnosis of epilepsy and other paroxysmal events Methods Video EEG monitoring under the state of awaking and sleeping and evoked tests were performed continuously in 216 patients with epilepsy and other paroxysmal events Results The characteristic events were captured in 130(60%) of the 216 patients And out of the 130 patients, 53 had clinical events accompanying epileptiform discharge 73 patients had no epileptiform discharge in both ictal and interictal period Seizure types were defined in 80%of 80 patients with epileptiform discharge, and classification was different from the original 42% of the 64 patients Conclusions Video EEG can record much more epileptiform discharge than routine EEG It should be an effective method in both diagnosis and classification of epilepsy

To discuss the protective effect of aralosides (AS) on I/R-induced rat myocardial injury. The adult rat ventricular myocyte ischemia model was established through perfusion with sodium lactate perfusate and reperfusion with Ca(2+) -containing Tyrode's solution simulation. The cell contraction and ion concentration synchronization determination system was applied to detect the effect of AS on single I/R cell contraction and Ca2+ transients. According to the findings, AS could increase resting sarcomere length, contraction amplitude, ± dL/dt(max), calcium transient amplitude and speed of post-reperfusion myocardial cells (P < 0.05, P < 0.01), and decrease in time for achieving 90.0% of maximum relaxation, time for achieving peak value, resting calcium ratio, contraction period [Ca2+] i, time for achieving 50.0% of maximum relaxation and attenuation rate of intracellular calcium transient (P < 0.05, P < 0.01). Therefore, it is suggested that AS improved the post-reperfusion cell contraction and injury of calcium homeostasis.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).

RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.

CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.
