Objective: To study the contents and constituents of LSPC (procyanidins from Lotus Seedpod) and its chemoprophylactic effects on 9,10-dimethyl-1,2-benzanthracene (DMBA)-induced golden hamsters buccal-pouch carcinomas. Methods: ESI-MS was used to analyze LSPC, and the change of body weight, mortality during test, and the value of serum MDA, GSH-Px, T-SOD,the gross and pathological change of buccal-pouch mucosa were investigated when golden hamsters were via gastric intubation or the buccal pouch mucosa was smeared with 100mg/(kg bw?d)LSPC. Results and conclusion: The contents of LSPC exceeded 98% and mono-, di-, tri-, tetrameric procyanidins as well as di-, trimeric galic ester were constituted of LSPC with molecular weight ranging from 290-1154. LSPC had chemoprophylactic effects on DMBA-induced golden hamsters buccal-pouch carcinomas, and the effect was superior through smearing LSPC rather then via gastric intubation .

Objective To discuss the signficance using nutrtional risk screening (NRS) to evaluate nutritional status in patients with severe stroke .In the meantime compare the clinical application value between enteral and parenteral nutritional support therapies .Methods A retrospective survey was adopted to analyze the nutritional status in 267 patients with severe stroke .Their nutritional statuses were evaluated by NRS 2002 nutrtional risk screening . Patients were divided into three groups ,including enteral nutrition (EN) group ,parenteral nutrition (PN) group and EN+ PN group based on the type of their nutritional support .By comparing changes of indicators before and after of adiministration of nutritional support ,the clinical efficacy and adverse reactions for each group were evaluated .Results In EN group and EN+ PN group total protein and albu-min level were significantly increased after 10 days nutritional support (P<0 .05) .Small changes in patients'liver and kidney function indices in EN group .The incidence of co-infection was 16 .67% in EN group ,which was lowest among three groups . Conclusion Enteral nutrition support could not only improve the nutritional status of patients with severe stroke ,but also could reduce the incidence of infections and gastrointestinal complications .It significantly improves the prognosis of patients .
