目的:测定硼硅酸盐玻璃的生物活性及其细胞相容性,开发一类以硼作为玻璃结构网络主要形成体的生物活性玻璃。方法:实验于2005-10/2006-08在上海同济大学材料科学与工程学院实验室完成。在硅酸盐生物玻璃,45S5玻璃,中引入B2O3,制备不同硼含量(摩尔百分比为15.4,30.7,46.1)的用于骨组织工程材料硼硅酸盐玻璃。以45S5玻璃为对照,通过X射线衍射方法确定生成羟基磷灰石晶体的速度,来评价硼硅酸盐的生物活性;在美国密苏里-罗拉大学生物实验室作成骨细胞在玻璃片上的接触实验和黏附试验,并通过扫描电镜和光学显微镜评价硼硅酸盐玻璃对成骨细胞的相容性。结果:①生物活性:随着硼含量提高,硼硅酸盐玻璃的羟基磷灰石生成速度加快,结晶度增加,说明它们的生物活性逐渐提高。②细胞相容性:与45S5玻璃相比,硼含量高的玻璃,对成骨细胞生长有抑制作用;但在玻璃片界面附近或玻璃片表面的成骨细胞,总体上仍然有较高的存活率,呈现出良好的生长形态。结论:硼硅酸盐玻璃是一类很有发展前景的骨组织工程支架材料,它不仅具有良好的生物活性,而且对成骨细胞具有较好的细胞相容性。

AIM: To identify plasma analytes using metabolomics that correlate with the diagnosis and severity of liver disease in patients with alcoholic hepatitis(ah).METHODS: We prospectively recruited patients with cirrhosis from ah(n = 23) and those with cirrhosis with acute decompen.a.ion.a.) from etiologies other than.a.cohol(n = 25). We used mass spectrometry to identify 29 metabolic compounds in plasma samples from fasted subjects. A receiver operating characteristics analysis was performed to assess the utility of biomarkers in distinguishing acute ah from alcoholic cirrhosis. Logistic regression.a.alysis was performed to build a predictive model for ah based on clinical characteristics. A survival analysis was used to construct kaplan Meier curves evaluating transplant-free ***: A comparison of model for end-stage liver disease(MELD)-adjusted metabolomics levels between cirrhosis patients who had AD or ah showed that patients with ah had significantly higher levels of betaine, and lower creatinine, phenylalanine, homocitrulline, citrulline, tyrosine, octenoyl-carnitine, and symmetric dimethylarginine. When considering combined levels, betaine and citrulline were highly accurate predictors for differentiation between.a. and AD(area under receiver operating characteristics curve = 0.84). The plasma levels of carnitine [0.54(0.18, 0.91); P = 0.005], homocitrulline [0.66(0.34, 0.99); P nd pen.a.oyl-carnitine [0.53(0.16, 0.90); P = 0.007] correlated with MELD scores in patients diagnosed with ah. Increased levels of many biomarkers(carnitine P = 0.005, butyrobetaine P = 0.32, homocitrulline P = 0.002, leucine P = 0.027, valine P = 0.024, phenylalanine P = 0.037, tyrosine P = 0.012, acetyl-carnitine P = 0.006, propionyl-carnitine P = 0.03, butyryl-carnitine P = 0.03, trimethyl-lisine P = 0.034, pen.a.oyl-carnitine P = 0.03, hexanoyl-carnitine P = 0.026) were associated with increased mortality in patients with ah.
