Objective To evaluate the effect of enteral nutrision (EN) containing dietary fiber complex (DFC) on intestinal mucosal barrier in rats with experimental colitis. Methods Ninety six SD rats were induced into ulcerative colitis by acetic acid enema.than were divided into 3 groups. The rats in group C received non-DFC nutrison, while the rats in group Tl or group T2 received soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) of the EN with different proportion (1:2 or 1:3, respectively). At the first-, third-,fifth- and seventh-day after the EN, the concentration of D-lactate and diamine oxidase (DAO) activity in plasma were detected and intestinal samples were obtained to observe the changes of intestinal mucosa. Results At the third-,fifth- and seventh-day,the D-lactate concentration and the DAO activity in plasma significantly reduced in group Tl and T2 when compared with group C (P<0. 05) , but there was no statistical difference between group Tl and group T2. The scores of histological damages of colon in the group Tl and group T2 decreased in comparison with group C at all time points (P < 0. 05). However, the scores of histological damages of colon significantly decreased in group T2 when compared with group Tl at day 5 and day 7 (P <0. 05). Conclusion EN containing DFC may reduce the intestinal permeability of colitis in rats, which has a protective effect on intestinal mucosal barrier. While different proportions of the SDF or IDF ratio result in different effects on the mucosal protection. This protective effect will be enhanced by increasing the ratio of IDF in a certain scale.

Objective: To investigate the effect of vascular endothelial growth factor-C (VEGF-C) on invasive capability and proliferation of human cholangiocarcinoma cells. Methods: The effect of VEGF-C on FRH0201 was assayed by MTT. The cycle pattern and apoptosis was assayed using flow cytometry. The effect of VEGF-C on homotypic adhesion and metastasis in FRH0201 was examined with 3H-TdR infiltration and Boyden chamber. Results: VEGF-C could enhance the proliferation of FRH0201 in a dose and time dependent manner. And VEGF-C could inhibit cell apoptosis significantly. After cultured for 2 hours with 1, 5, 10ng/ml of VEGF-C, there were more cells in the lower chamber than the control group. After 60, 90, 120 minutes induction by 1ng/ml、5ng/ml、10ng/ml, the cells showed significantly lower homotypic adhesion than that of the control group. Conclusions: VEGF-C could enhance the proliferation of FRH0201 and inhibit cell apoptosis. VEGF-C could decrease homotypic adhesion of FRH0201 and might be a cause of the metastasis.

Phosphodiesterase-5 inhibitors (PDE5i) have been used as the first-line treatment for erectile dysfunction (ED) in recent years. However, with the increased clinical application of PDE5i, the incidence rate of PDE5i-induced adverse reactions is on the rise, which may involve the cardiovascular, digestive, nervous, respiratory, and reproductive systems. Most of the adverse reactions are mild to moderate, occasionally with serious or rare complications. The probability and severity of the adverse reactions are associated with the dosage and frequency of medication as well as with individual differences. Therefore individualized medication is necessitated and, for the patients with cardiovascular disease, epilepsy, psychosis, or anaphylactic conditions, PDE5i should be cautiously given or avoided. This review provides an overview of PDE5i-induced adverse reactions and countermeasures in the treatment of ED.

BACKGROUND:With the consumption of acidic beverages, dental erosion becomes more serious. Erosion is related to direct loss of dental hard tissue, and causes dental over-abrasion, thus great threatening the dental health.
OBJECTIVE:To review the research work on the erosion of human teeth, erosion prevention, and teeth remineralization.
METHODS:A computer-based online retrieval of CNKI, Elsevier and Wiley databases between 1990 and 2013 was performed for articles abut human teeth erosion, erosion prevention and teeth remineralization. After repeated or old literatures were excluded, 58 literatures were included in the analysis.
RESULTS AND CONCLUSION:Current studies on dental erosion included three aspects, firstly, clinical observation of the symptoms and cause of dental erosion;secondly, the erosiveness of common acidic agents;and thirdly, the prevention of dental erosion. Many researchers focused on the prevention of dental erosion. It was suggested that dental erosion could be prevented through adjusting and control ing oral environment, enhancing the erosiveness of acidic beverages, and increasing the anti-erosion capacity of teeth. It should be noted that tooth erosion and friction/wear often occur simultaneously in the mouth. Therefore, future research should pay attention to the interaction mechanism of erosion, friction and wear of human teeth.
