The aim of this study was to evaluate the probiotic effects of Lactobacillus strains against Vibrio parahaemolyticus causing gastroenteritis. Six-week-old ICR mice were pretreated with four Lactobacillus strains at three dosages, and then challenged with V. parahaemolyticus TGqx01 (serotype O3: K6). The results showed that V. parahaemolyticus TGqx01 caused severe intestinal fluid accumulation ( FA) and villi damage in control mice which were pretreated with phosphate-buffered saline. In contrast, significant alleviation of FA was seen in mice pretreated by with a high dose of Lactobacillus strains ( P < 0.05, n = 6) but not in mice that received low-dose pretreatments. Among middle-dose treatments, two highly adhesive strains, Lactobacillus rhamnosus H15 and Lactobacillus brevis Y29-4, significantly decreased intestinal FA and villi damage in treated mice ( P < 0.05). Two low-adhesive strains, Lactobacillus acidophilus Y14-3 and Lactobacillus fermentum F16-6, had no significant alleviating effects. At the same dosing levels, no significant differences in FA were observed in mice pretreated with strains with similar adhesive abilities but different antagonistic activities. Our findings suggest that Lactobacillus strains can alleviate V. parahaemolyticus-induced intestinal FA in mice, and the doses required for in vivo efficacy depend more on adhesive ability than on the antibacterial activity of strains.

Objective: To observe the clinical effect of Chinese medicine Sansheng Huatan Decoction combined with chemotherapy in treating advanced primary non-small-cell lung cancer and to evaluated the effect of Sansheng Huatan Decoction increasing clinical effect and decreasing toxicity in chemotherapy for non-small-cell lung cancer., Methods: One hundred and sixty patients of advanced primary non-small-cell lung cancer proved by pathological examination were randomized into two groups. The treatment group was treated with Sansheng Huatan Decoction and chemotherapy, and the control group was treated only with chemotherapy. The clinic effect, life quality, natural killer (NK) activities, liver and kidney functions, and blood routine test of the 2 groups were evaluated., Results: The clinical effective rates of the treatment and control groups were 56.7% and 48.2% respectively, and there was no statistic significance (P>0.10). The life quality, NK activities and blood routine test of the treatment group were better than those of the control group., Conclusion: Sansheng Huatan Decoction combined with chemotherapy is a better treatment for non-small-cell lung cancer as compared with chemotherapy.
