AIM: To assess the risk of relapse in ulcerative colitis (UC) patients in clinical remission using mucosal status and fecal immunochemical test (FIT) ***: The clinical outcomes of 194 UC patients in clinical remission who underwent colonoscopy were based on evaluations of Mayo endoscopic subscores (MESs) and FIT ***: Patients with an MES of 0 (n = 94, 48%) showed a ten-fold lower risk of relapse than those with an MES of 1-3 (n = 100, 52%) (HR = 0.10, 95%CI: 0.05-0.19). A negative FIT result (fecal hemoglobin concentrations ≤ 100 ng/mL) was predictive of patients with an MES of 0, with a sensitivity of 0.94 and a specific of 0.76. Moreover, patients with a negative FIT score had a six-fold lower risk of clinical relapse than those with a positive score (HR = 0.17, 95%CI: 0.10-0.28). Inclusion of the distinguishing parameter, sustaining clinical remission > 12 mo, resulted in an even stronger correlation between negative FIT results and an MES of 0 with respect to the risk of clinical relapse (HR = 0.11, 95%CI: 0.04-0.23).CONCLUSION: Negative FIT results one year or more after remission induction correlate with complete mucosal healing (MES 0) and better prognosis. Performing FIT one year after remission induction may be useful for evaluating relapse risk.

制备了低碱度硫铝酸盐水泥,并对由该水泥制备的砂浆和混凝土的物理性能进行了测试分析。结果表明:低碱度硫铝酸盐水泥砂浆和混凝土的抗压强度发展良好,过量的缓凝剂会降低其早期强度。在水灰比为0.65的情况下,其砂浆和混凝土的长期抗压强度发展缓慢。水灰比和抗压强度之间不存在线性关系。新拌混凝土会出现体积收缩,但随之转变为体积膨胀,并持续10～30d。当粉煤灰和石灰石粉作为掺合料替代部分水泥时,其砂浆和混凝土的强度会下降,但仍能满足实际应用的要求;此外,粉煤灰和石灰石替代部分水泥还能减小混凝土的绝热温升、改善其流动性。

关键词：低碱度硫铝酸盐缓凝剂新拌性能硬化性能
