The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D. officinale attached to different tree species, but the differences had no relationship with the form and nutrition of barks. The polysaccharides content of D. officinale mainly affected by the light intensity of environment, so reasonable illumination favored the accumulation of polysaccharides. Various polysaccharides content of D. officinal from different attached trees is due to the difference of light regulation, but not the form and nutrition of barks.

Objective To investigate the change of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the skin of diabetic rats, and to explore the potential role of MMP-9/TIMP-1. Methods Diabetic rats were induced with streptozotocin (STZ). Then all rats were maintained for 6 weeks. Routine pathological examination and immnnohistochemistry were made to reveal the histological and cytological appearances. RT-PCR and Western blotting were used to detect the expression of mRNA and protein of MMP-9 and TIMP-1 in the skin. Results Six weeks after STZ treatment, examination of HE-stained skin sections from normal and diabetic animals revealed that the epidermis and dermis layers were thinner in diabetic rats than those in control rats. The skin of diabetic rats showed features of atrophy such as disorganization of connective tissue fiber bundles and enlarged space between collagen fiber bundles. In contrast, thick bundles of connective tissue were observed in the dermis of normal rat skin. In normal skin, cells had a bipolar, spindle-shaped appearance in the thick collagen bundles, while in the skin of diabetic animals the interstitial cells had a rounded, shrunken and crenated appearance. The relative values of expression of MMP-9 in diabetic group were higher than those in normal group with significant difference, however, the relative values of expression of TIMP-I in diabetic group were lower than those in control group. Conclusion The changes in cutaneous histology and cytology appear earlier than skin wound. These "underlying disorders" may be associated with the imbalance of MMP-9/TIMP-1.
