Objective To study effect of TCM-based syndrome differentiation combined with diet nursing and point massage on insomnia.Methods Five hundred and twelve patients with insomnia were randomized into control group(n=85)and intervention group (n=67).The patients in both groups received treatment by TCM-based syndrome differentiation.Besides,the control group was given conventional nursing while those in the intervention group received diet nursing and point massage.The two groups were compared in three months in terms of sleep quality and curative effect.Results In comparisons of sleep quality index,the two groups both had statistically significant improvements respectively(both P<0.05).In terms of time to sleep, duration of sleep an sleep efficacy and Pittsburg sleep quality index,the intervention group scored significantly lower than the control group(all P<0.05).In terms of curative effect,the intervention group was significantly higher than the control group(P<0.05).Conclusion The method of TCM-based syndrome differentiation combined with diet nursing and point massage is effective in improving the sleep quality of those with insomnia.

OBJECTIVETo characterize the structure of polysaccharide LTC-II obtained from Pyrola corbieri.

METHODThe polysaccharide was extracted from P. corbieri by hot water and ethanol precipitation. Crude polysaccharide was purified by DEAE-Cellulose chromatography and Sephacryl S-300 HR column chromatography. The purity and molecular weight of polysaccharide was determined by gel permeation chromatography. UV, IR, optical rotation, complete acid hydrolysis, periodate oxydation, Smith degradation, partial acid hydrolysis and methylation analysis were applied to determine the structural features.

RESULTA homogeneous fraction LTC-II was obtained and its relative molecular mass was 22 000 Da. It consisted of arabinose, mannose, glucose, galactose in the molar ratio of 35. 2: 1.0: 13. 4: 4. 2. LTC-II had a backbone consisting glucose, mannose, galactose and mainly contained (1 --> 6)-linkaged glucose. The side chain possessed arabinose, glucose, galactose and mainly contained (1 --> 5)-linkaged arabinose. The terminal sugar were mainly glucose and galactose.

CONCLUSIONStudies on the preliminary characterization of polysaccharide LTC-II from P. corbieri for the first time.
