To observe the effect of cyanidin-3,5-O-diglucoside(C3G) on intestinal fibrosis in a model of dextran sulphate sodium (DSS)-induced mice with colitis. Colitis was induced in C57BL/6 mice by addition of DSS to drinking water. Clinical (body weight, colon length and colon weight) and histologic changes were evaluated. In addition, colon levels of interleukin-1β, IL-6, IL-18, IL-17A, tumor necrosis factor(TNF)-α were detected by enzyme-linked immunosorbent assay. Relative to the DSS group, the mice in the C3G treatment group increased in body weight, colon length, and the ratio of colon weight to length was significantly lower (P<0.05). The DAI index of mice in the intervention group was lower than that in the colitis model group (P<0.05). Histological observation also found that the intervention of C3G is able to reduce the infiltration of inflammatory cells in colon tissue induced by DSS. The results of Masson staining suggest that the intervention of C3G also reduces the occurrence of intestinal fibrosis in mice with colitis. Our results suggested that C3G is an activity to improve inflammation and intestinal fibrosis in DSS colitis mice.

In this research, we used a twin-screw extruder to melt and blend PP-g-MA compatibilizer with bpolypropylene (PP)/polyamide 6 (PA6). The influences of the PA6 and PP-g-MA contents in PP/PA6 blends on crystallization and melting behavior of PP phase and morphology were investigated. The results showed that, when PP-g-MA copolymer was added to the b form of nucleated PP/PA6 blends, the anhydride groups in PP-g-MA and PA6 terminal amine groups react to form PP-g-PA graft copolymer in a two-phase interface. This reduces the interfacial tension, improves the interfacial adhesion, and reduces the size of PA6 domains in the blend. The generated PP-g-PA graft copolymer wrapped PA6 phase and buried the anhydride groups of PP-g-MA. When the proportion of PP-g-MA and PA6 was between 0.5 and 0.75, there was no longer interfering to the formation of b-crystals in the PP phase. The content of bcrystal of PP phase in blends was found to reach as large as 85.9%.

To explore the effect of C3G on intestinal mucosal injury in 5-FU induced BALB/c mice. Mice were randomly divided into normal, model and C3G groups. After the last administration, mice were anesthetized, and calculated the thymus and spleen indexes. The ileum was used to stain with H&E observation. Serum levels of IL-1β, IL-6, IL-10 and TNF-α were determined by ELISA kits. Compared with the normal group, the model group had diarrhea, body weight and thymus and spleen index decreased significantly, intestinal villus epithelial cells fell off, crypt structure was destroyed, and inflammatory cell infiltration was observed. The body weight, thymus and spleen indexes of the treatment group and the prevention group decreased less, and the levels of TNF-α, IL-1β and IL-6 were significantly decreased, and the level of IL-10 was significantly increased relative to the model group. The intestinal villi structure was relatively complete, and a small amount of crypt structure was destroyed, with a small amount of inflammatory cell infiltration, which reduced the mucosal damage. The administration of C3G could protect intestinal mucosa from 5-FU-induced injury.

To investigate the effects of AMP on letrozole-induced PCOS rats. All SD rats were randomly divided into normal, PCOS, metformin group (Met, 265 mg/kg) and AMP group (1 g/kg) and weighed every three days. After 21 days of continuous administration, oral glucose tolerance test was performed, and the blood glucose(BP) level was measured. After execution, calculate the relative weight of bilateral ovaries. Serum levels of FSH, LH, E2, T and FINS were detected by ELISA assay. Serum levels of TC, TG, HDL-C and LDL-C were detected by the kit and calculated the LH/FSH ratio and HOMA-IR level. Compared with the normal group, body weight and relative weight of ovaries, BP level and serum levels of T, LH, LH/FSH ratio, FINS, HOMA-IR, TC, TG, LDL-C, and E2, FSH, HDL-C in model group increased. Compared with the PCOS group, body weight in the Met group and AMP group was lower, BP level and serum levels of T, LH, FINS, HOMA-IR and LDL-C in the Met group and AMP group were significantly lower and the level of HDL-C was higher. Armillaria mellea polysaccharides can improve hormone disturbance, glucose metabolism and abnormal lipid level in letrozole-induced polycystic ovary syndrome model rats.

To observe the effect of SA on DSS-induced intestinal fibrosis in mice. The mice were randomly divided into normal, DSS and SA treated DSS mice group. Changes in body weight(BW), blood stool and diarrhea were observed. The serum levels of IL-1β, IL-6, IL-17A, IL-18 and TNF-α were determined by ELISA kits. The protein levels of NLRP3, caspase-1, ASC, IL-1 β, α-SMA, CollagenI, Beclin1, LC3II/I and p62 were detected by Western Blotting assay. Compared with the normal group, SA significantly inhibited the loss of BW and DAI score in colitis mice (P<0.05). H&E and Masson staining assay suggested the SA reduced epithelial cell damage, crypt structure loss, inflammatory cell infiltration, and the fibrogenesis in colon of colitis mice. The serum levels of IL-1β, IL-6, IL-17A, IL-18 and TNF-α were decreased by SA(P<0.05). SA was able to reduce the protein levels of NLRP3, Caspase-1, ASC, IL-1β, α-SMA, Collagen-I, p62, and increased the expressions of Beclin1 and LC3II/I in colitis mice. The study demonstrated that SA can modulate the activity of NLRP3 inflammasome and autophagy pathway to improve DSS induced intaestinal fibrosis in mice.

It has been observed that the formation of b-crystal is suppressed when b-polypropylene (b-PP) is blended with crystalline polymers, but the reason is still uncertain. In this study, we investigated the influence of the crystallization conditions of polytrimethylene terephthalate (PTT), such as melt crystallization, cold crystallization, isothermal crystallization temperature, and crystallization time on the b-nucleation behavior of PP phase in the b-PP/PTT blends. The results showed that the b-crystal content of PP phase in the blends decreases with increasing of PTT content. Cold crystallization of PTT would mainly induce the formation of a-crystal in PP component, whereas melt crystallization would induce the formation of b-crystal PP in their blends. The degree of crystallinity of PTT increases by improving the crystallization temperature or extending the time of crystallization, which leads to the production of more a-crystal in PP component. This means that the second component could inhibit the formation of b-crystal in PP.

Background: The purpose of this research was to assess the role of heparanase (HPSE)/syndecan1 (SDC1)/nerve growth factor (NGF) on cancer pain from melanoma. Methods: The influence of HPSE on the biological function of melanoma cells and cancer pain in a mouse model was evaluated. Immunohistochemical staining was used to analyze HPSE and SDC1. HPSE, NGF, and SDC1 were detected using western blot. Inflammatory factors were detected using ELISA assay. Results: HPSE promoted melanoma cell viability, proliferation, migration, invasion, and tumor growth, as well as cancer pain, while SST0001 treatment reversed the promoting effect of HPSE. HPSE up-regulated NGF, and NGF feedback promoted HPSE. High expression of NGF reversed the inhibitory effect of HPSE down-regulation on melanoma cell phenotype deterioration, including cell viability, proliferation, migration, and invasion. SST0001 down-regulated SDC1 expression. SDC1 reversed the inhibitory effect of SST0001 on cancer pain. Conclusions: The results showed that HPSE promoted melanoma development and cancer pain by interacting with NGF/SDC1. It provides new insights to better understand the role of HPSE in melanoma and also provides a new direction for cancer pain treatment.

This study was to investigate the ameliorative effect of GFPS on clinical symptoms in letrozole(1 mg/kg)-induced PCOS rats. The female SD rats were classified into 4 groups as follows: the normal group (gavaged with saline), the PCOS group(ingested letrozole daily for 21 days). Normal group and metformin group gavaged with letrozole followed by metformin (265 mg/kg) and GFPS(600 mg/kg), respectively. All rats were weighed every 3 days until the end of the experiment. The ovaries, perirenal, abdomen and periuterine fat were removed and the relative weights (g/bw×100) were calculated. Serum levels of FSH, LH, E2, T, TG, TC, LDL-C were measured by ELISA and calculated the LH/FSH ratio. GFPS reduced follicle number and increases granulosa cell layer thickness and luteal number. GFPS also reduced the increase of body weight, ovarian and visceral fat weight in PCOS rats (P<0.01). In addition, GFPS reduced the serum levels of T, LH/FSH, TC, TG, LDL-C and LH, and elevated the serum levels of E2 and FSH in PCOS rats. In conclusion, GFPS can improve follicular development and restore body weight, ovarian weight, serum hormone levels and lipid profile in PCOS rats.
