BACKGROUNDRecently, new anti-epileptic drugs (AEDs) have been more frequently selected to treat epilepsy. In the present study, we evaluated the dynamic changes of efficacy and safety of three newer AEDs for treating partial epilepsy in China.

METHODSPatients were collected sequentially and were divided into three groups which accepted oxcarbazepine (OXC), lamotrigine (LTG) or topiramate (TPM) therapy. Each group included monotherapy and add-on therapy subgroups. We followed all patients for one year and recorded the indexes of efficacy and safety in detail.

RESULTSA total of 909 patients finished the follow-up observation. No significant difference was found in proportion of patients with > or = 50% reduction, > or = 75% reduction and 100% seizure reduction in the LTG and OXC groups between the first and the second six months. In the TPM group there was a statistical difference between the first and the second six months in proportion of patients with > or = 50% reduction (P = 0.002), > or = 75% reduction (P < 0.0001) and 100% seizure reduction (P = 0.009) in the monotherapy subgroup, and about > or = 75% reduction and 100% seizure reduction in the add-on therapy subgroup (P < 0.0001). The efficacy between the add-on and monotherapy subgroups showed a statistical difference. The safety of the three newer AEDs was good.

CONCLUSIONSThe three newer AEDs all showed good efficacy and tolerability for partial epilepsy. And the efficacy can be maintained for at least one year.

OBJECTIVETo investigate the active constituents from Rumex dentatus.

METHODCompounds were isolated by silica gel, Sephadex LH -20 and ODS column chromatography and identified by chemical and spectroscopic methods.

RESULTTen compounds were obtained and identified as helonioside A (1), gallic acid (2), isovanillic acid (3), p-hydroxycinnamic acid (4), succinic acid (5), n-butyl-beta-D-fructopyranoside (6), quercetin (7), hexadecanoic acid 2, 3-dihydroxy propyl ester (8), beta-sitosterol (9) and daucosterol (10).

CONCLUSIONCompounds 1, 3-6 and 8 were isolated from the genus of Rumex for the first time.

Infantile spasm is an age-related refractory epilepsy. Topiramate is a new anticonvulsant with multiple mechanisms of action, and it may be effective for treating pediatric epilepsies. To evaluate the efficacy and tolerability of first-line topiramate treatment for infantile spasm, 20 patients received topiramate monotherapy during this study. They were treated with an initial dose of 1mg/kg/day, with a progressive titration of 1 mg/kg a week until their spasms were controlled and a maximum dose of 12mg/kg/day was achieved. The evaluation of the treatment efficacy was based on the spasm frequency data that was obtained by the scalp and video-EEG, and by the parental count of spasm. Thirty percent of the subjects became spasm-free during the study. Six of 20 subjects (30%) had cessation of spasm and disappearance of hypsarrhythmia as seen via the video EEG; four (50%) of eight idiopathic patients had a response, whereas two (17%) of 12 patients with symptomatic infantile spasm responded. Seventy of the patients, including the spasm-free patients, had a reduction in their seizure frequency of more than 50%, and 10% of the patients had a reduction in their seizure frequency of less than 50%. The clusters of spasm frequency decreased from 10.6 +/- 8.5 to 3.5 +/- 1.4 clusters/day. Topiramate is effective and tolerated in those patients suffering from infantile spasm. Our results suggest that this drug should be considered as a new first-line drug for treating infantile spasm.

The origin of 5-HMF (5-hydroxymethyl-2-furaldehyde) in a Shengmaiyin decoction was investigated by the RP-HPLC method below. A C(18) column (250 mm x 4.6 mm, i.d. 5 microm) with a column temperature of 25 degrees C was used. The mobile phase was a mixture of ultra-pure water-acetonitrile (95:5, V/V) and the flow rate was 1.0 ml/min. The detection wavelength was 280 nm. The injection volume was 1 microl and the running time was about 20 min. The addition of Schisandra was regulated to assess the contribution of an acid environment to the production of 5-HMF. In order to confirm the role of saccharides in the production of 5-HMF, different amount of fructose was used. The 5-HMF level in decoctions of processed and unprocessed Schisandra was investigated in order to determine the origin of 5-HMF. The results showed that 5-HMF was derived mainly from the decoction of Schisandra only and not the mixed decoction of Ophionpogon and Schisandra. The appearance of 5-HMF is not simply the result of the decomposition of saccharides under the acid environment created by Schisandra, but the processing procedure plays an important role in the production of 5-HMF.

AIMTo investigate the glycosidic constituents in the rhizomes of Alpinia officinarum Hance.

METHODSThe isolation and purification of glycosides were done with column chromatography on macro porous resin, polyamides and Sephadex LH-20, whilst the structure elucidation was done by HRCI-MS and NMR (1D and 2D) methods.

RESULTSA glycosidic ester identified as 4'-hydroxy-2'-methoxyphenol-beta-D-{6-0-[4"-hydroxy-3", 5"-dimethoxy (benzoate)]}-glucopyranoside (I), along with a known compound n-butyl-beta-D-fructopyranoside (II), were isolated and characterized.

CONCLUSIONI was found to be a new compound, named as alpinoside A, whilst II was isolated from the genus Alpinia for the first time.
