This study is to investigate the anti-allergic effect of anthocyanidin and to explore its possible mechanism. The experiments of passive cutaneous anaphylaxis reaction (PCA) and colorimetry were used to determine the effect of anthocyanidin on degranulation of mast cells in vivo. For in vitro study, various concentrations of anthocyanidin (100, 50 and 25 micromol x L(-1)) were added to the culture medium of mast cells cultured with 100 microg x L(-1) of dinitrophenyl (DNP) specific IgE overnight. The azelastine (100 micromol x L(-1)) was selected as the positive control. The antigen (DNP-human serum albumin, DNP-HAS)-induced release of degranulation was measured by enzymatic assay, histamine was determined by EIA, and interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured by Western blotting, separately. In addition, the effects of anthocyanidin on phosphorylation of NF-kappaB, p38MAPK and Akt were observed by Western blotting. The results showed that treatments with anthocyanidin (100 and 50 mg x kg(-1)) were followed by a decrease in PCA of rats. Anthocyanidin (100 and 50 micromol x L(-1)) obviously suppressed the degranulation from mast cells, whereas results from anthocyanidin (100 and 50 micromol x L(-1)) group indicated significant inhibitory effect on histamine, the calcium uptake, TNF-alpha, IL-6, phosphorylation of NF-kappaB, p38MAPK and Akt of mast cells induced by antigen. Anthocyanidin may suppress the anaphylactic reaction by inhibiting the action of mast cells. NF-kappaB, p38MAPK and Akt at least in part contribute to this event.

Objective To study the influence of fluoride on the expression of Runx2 in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarium of suckling Wistar rats were cultured in the media supplemented with NaF at different doses(0, 1,2 and 4 rag/L), and Runx2 Mrna expression and protein expression were evaluated by RT-PCR and ELISA, respectively. Results Runx2 Mrna expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h at different doses (0.613±0.055, 0.773±0.070 and 0.775±0.070 for 1,2 and 4 mg/L,respecfively) compared to the control (0.482±0.043 ,P< 0.05). Runx2 Mrna expression further increased after 72 h exposure to NaF(0.969±0.048,1.229±0.061,1.255± 0.063 for 1,2 and 4 mg/L, respectively) ,which is significantly higher than the control(0.724±0.036,P<0.05) and corresponding groups at 48 h. NaF doses and exposure time exhibited a significant synergistic effect on Runx2 Mrna expression (P<0.05). Similarly, NaF also enhanced Bunx2 protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed between groups exposed to NaF (1,2 and 4 rag/L) and control at48 h post-exposure (0.141±0.007, 0.143±0.008, 0.143±0.011 vs 0.129±0.012, P<0.05) as well as 72 h post-expesure(0.156±0.014, 0.168±0.018, 0.162±0.0100 vs 0.137±0.016, P<0.05). In addition, Runx2 protein expression at 72 h post-exposure was significantly higher than that at 48 h. Conclusions The results suggested that NaF could increase Runx2 expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

BACKGROUNDThe cholesterol-lowering statin drugs have some non-lipid-lowering effects, such as inhibiting myocardial remodeling. However, the underlying mechanism is still unclear.

METHODSThe left anterior descending coronary artery was ligated to establish a rat model of heart failure, and the rats were divided into a sham operation (SO) group, myocardial infarction model (MI) group, and MI-atorvastatin group. Changes in hemodynamic parameters were recorded after the final drug administration. Histological diagnosis was made by reviewing hematoxylin and eosin (HE) stained tissue. Real-time quantitative polymerase chain reaction (PCR) was performed to determine the expressions of type I and type III collagen, matrix metalloproteinase-2 (MMP-2), and tissue matrix metalloproteinase inhibitor-2 (TIMP-2). Further, primary rat cardiac fibroblasts were cultured and the MTT assay was performed to determine the effect of atorvastatin on cardiac fibroblast proliferation.

RESULTSThe model of heart failure was established and the results of HE staining and Masson's trichrome staining revealed that the rats in the heart failure group showed obvious hyperplasia of fibrotic tissue, which was significantly reduced in the atorvastatin group. Real-time quantitative PCR showed that the MI group showed a significantly increased expression of type I and type III collagen, MMP-2, and TIMP-2, but a significantly reduced MMP-2/TIMP-2 ratio. Compared with the MI group, the atorvastatin group showed significantly reduced expression of type I and III collagen, unchanged expression of MMP-2, significantly reduced expression of TIMP-2, and an increased MMP-2/TIMP-2 ratio. We further found that atorvastatin significantly inhibited the Ang II-induced fibroblast proliferation and the expression of type I and type III collagen in cardiac fibroblasts while increasing the MMP-2/TIMP-2 ratio.

CONCLUSIONSThese data suggest that atorvastatin can inhibit cardiac fibroblast proliferation and enhance collagen degradation by increasing the MMP-2/TIMP-2 ratio, thereby inhibiting the formation of myocardial fibrosis in rats with heart failure after myocardial infarction.

OBJECTIVESTo evaluate the characteristic morphology of heel spur, and to investigate the relationship of heel spur and plantar heel pain.

METHODSFrom June 2005 to April 2009, 210 cases (254 feet) with heel spur (according to Denis Pain Scale) were divided into cases group 1 (P2, n = 46), 2 (P3, n = 44), 3 (P4, n = 42), 4 (P5, n = 36) and controls group (P1, n = 42). Three-dimensional reconstruction of heel spur was performed in all groups using volume rendering based on multi-slice CT data by Super Image orthopedics edition 1.0. The characteristic morphology of heel spur was observed and the data were measured and analyzed, involving the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.

RESULTSParts of cases groups displayed coarse arcuate edge and undersurface with one or more little heel spurs adhere to heel spur, of which the numbers were greater than controls group, especially in cases group 4. No significant difference of the width of basilar part of heel spur was found among 5 groups (F = 2.32, P > 0.05). However, obvious difference was found in the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur (F = 8.23, 6.82, 5.87, P < 0.05). Compared with the controls group, the angle between heel spur and planta pedis of cases groups had higher degrees, but the difference of the other data presented irregular.

CONCLUSIONSThe characteristic morphology of heel spur varies in patients associated with plantar heel pain. No correlation is found between the severity and the morphological data, including the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.

OBJECTIVETo investigate prevalence, location, negotiation and the effect of operating microscope (OM) in the treatment of the second mesiobuccal canal (MB2) in maxillary molars.

METHODS113 maxillary molars were studied. The crowns of the teeth were removed 1 mm above the chamber bottom for searching MB2 canal. Initially location and negotiation of MB2 canal were attempted without OM. Teeth in which MB2 canal were not located or negotiated were further explored under OM. Canal orifices including MB orifice, MB2 orifice and palatal orifice were filled by red gutta-percha cones, then the teeth were scanned by scanner. The images were analyzed by Image-Proplus 4.0 software to measure the relationship between MB2 canal and other canals.

RESULTSThe MB-MB2 distance is (1.47 +/- 0.54) mm, MB-P distance is (5.77 +/- 0.66) mm, the vertical distance from MB2 to MB-P line is (0.53 +/- 0.28) mm, the angle between MB-P line and MB-MB2 line is 23.07 degrees +/- 13.08 degrees. MB2 orifices were located in 70 teeth (61.9%) and negotiated in 53 teeth (46.9%) without OM. With OM, additional MB2 orifices were located in other 6 teeth, 4 were negotiated; and 2 were negotiated in which MB2 canal were not negotiated without OM.

CONCLUSIONSMB2 canal can be located in 67.3% and negotiated in 52.2% of maxillary molars. Ability to locate and negotiate MB2 canal is facilitated by OM. The MB2 canal was located less than 1 mm mesially to the MB-P line and 2 mm palatally from the MB orifice.
