Objective To observe and identify the impact of a type of macro?pore bone block bioactive glass on osteo?blast in vitro. Methods Extract fluid of new bioactive glass was prepared withα?MEM culture medium as the bioactive medium group. And the concentrations of different ions were detected with Inductively Coupled Plasma?Atomic Emission Spectrometry in bioactive medium group andα?MEM medium group. MC3T3?E1 cells cultured in bioactive medium group were considered as ex?perimental group and cells cultured inα?MEM medium as control group. Giemsa and immunofluorescence staining was performed to detect the cell numbers, the karyoplasmic ratio and the average fluorescence intensity per cell. Cell proliferation and viability in different groups were detected by cell cycle analysis, MTT assay and BrdU assay, respectively. Total RNAs of cells in different groups were extracted and the expressions of ALP, OCN and collagenⅠwere measured by quantitative real time PCR. ALP stain?ing and alizarin red staining were performed to assess the differentiation and mineralization of MC3TC?E1 cells in different groups. Results The concentrations of Si and F were 40.02 ± 0.67 mg/L and 0.02 ± 0.001 mg/L in bioactive medium group, higher than 2.02±0.01 mg/L and 0.00 mg/L inα?MEM solution, and the concentration of Ca was lower than that inα?MEM solution. The con?centration of P and Na had no difference. In Giemsa staining, the cell number in 400 times field under a microscope was 106.0 ± 6.025 in bioactive medium group and 40.20 ± 3.639 inα?MEM medium group. In the immunofluorescence of vinculin, the karyo?plasmic ratio and the expression of vinculin were higher in bioactive medium group (40.85±5.720, 0.050 88±0.021 78) than inα? MEM medium group (21.93 ± 4.137, 0.023 60 ± 0.003 18). In cell cycle analysis, the proportion of cells retained in S and G2/M phase in the bioactive medium group was more than that in theα?MEM medium group after 72 hours of cell culture. In the BrdU and MTT assay, MC3T3?E1 cells in bioactive medium group both showed a higher proliferation rate with statistical significance. In MC3T3?E1 cells cultured with the bioactive medium, the expressions of osteogenesis?related genes were higher than those cultured with ordinaryα?MEM solution;in the ALP staining and alizarin red staining, the expression of ALP and the mineralization rate were higher in bioactive medium group (1.328%±0.015 36%, 2.953%±0.536 3%) than inα?MEM medium group (0.979%±0.030 59%, 1.000%±0.208 1%). Conclusion The bioactive medium promotes cell proliferation and osteoblastic differentiation of MC3T3?E1 cells, and has much more Si ions, which indicates that macro?pore bone block bioactive glass can promote cell proliferation and dif?ferentiation and has promising bioactivity.

Objective To investigate the relationship of omentin-1 with adiponectin and inflammatory cytokines in type 2 diabetes (T2DM) patients with nonalcoholic fatty liver disease (NAFLD). Methods The serum levels of omentin-1 and adiponectin were assayed by enzyme-linked immunosorbent assay (ELISA) in patients of T2DM with NAFLD (group A, n=63), T2DM without NAFLD (group B, n=63)and normal control group (group C, n=70). At the same time the biochemical markers and inflammatory marker, such as tumor necrosis factor (TNF)-α, high-sensitivity C-reactive protein (hs-CRP) and interleukin 6(IL-6) were detected in three groups. The correlation analysis and multiple regression analysis were used to de-tect the association of omentin-1 with adiponectin and inflammatory markers. The logistic regression was used to analyze fac-tors influencing NAFLD in patients with T2DM. Results The serum levels of omentin-1 and adiponectin were significant-ly lower in group A [ (27.02±2.82)μg/L and (11.98±3.63) mg/L] than those of group B [(31.52±2.81)μg/L and (15.85±3.28) mg/L] and group C [(35.92±2.80)μg/L and (19.88±3.44) mg/L], and there were significantly lower levels of them in group B than those of group C (P<0.01). The plasma omentin-1 level was positively correlated with adiponectin and high density li-poprotein (HDL-C) in group A. Also the plasma omentin-1 level was negatively correlated with TNF-α, IL-6, fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), visceral adipose tissue, waist, waist-to-hip ratio (WHR) and free fatty acid in group A (P<0.05 or P<0.01). Multiple stepwise regression analysis showed that adipo-nectin, TNF-αand IL-6 were independent factors influencing the level of plasma omentin-1. Logistic regression analysis showed that omentin-1 was one of independent factors influencing T2DM combined with NAFLD (P<0.01). Conclusion The incident of NAFLD in T2DM patients is related to the lower level of omentin-1, which may be influenced by adiponectin and inflammatory factors.

Objective To investigate the relationship between plasma soluble CD36 (sCD36) and nonalcoholic fatty liver disease (NAFLD) in patients combined with type 2 diabetes mellitus (T2DM). Methods Plasma levels of sCD36 were determined in normal control group (group A, n=39), patients of T2DM without NAFLD group (group B, n=39) and T2DM with NAFLD group (group C, n=59). Liver fat content (LFC) and nonalcoholic fatty liver fibrosis score (NFS) were calculated in group C. Glucose and lipid metabolic parameters, liver function parameters and inflammatory parameters were also detect?ed in all three groups. Variance analysis was applied to analyze the differences of the above parameters among three groups;Correlation analysis was used to analyze the relationship between sCD36 level and all the above parameters;Multiple step? wise regression analysis was applied to determine the influencing factors of sCD36 level in patients of group C. Results Plasma sCD36 (μg/L) levels in group B (3.87 ± 1.16) and group C (5.72 ± 1.79) are higher than that of group A (2.57 ± 0.93) (both P<0.01), and it is higher in group C than in group B (each P<0.05);Correlation analysis showed that sCD36 level was positively correlated with body mass index (BMI), waist, visceral adipose tissue,fast insulin (FINS), insulin resistance in?dex (HOMA-IR), free fatty acid (FFA), alanine transaminase (ALT), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), LFC and NFS (P<0.01 or P<0.05);Multiple stepwise regression analysis showed that FFA, LFC, TNF-αand IL-6 were in?fluencing factors of sCD36 level in patients of group C. Conclusion Plasma sCD36 level was related to fatty liver severity, liver injury and fatty liver fibrosis, it might be used as a plasma marker of T2DM combined with NAFLD. CD36 might con?tribute to the development of T2DM combined with NAFLD through inflammatory mechanisms.
