利用马弗炉高温真空煅烧碳酸钙烧制氧化钙熟料,后经XRD分析煅烧熟料矿物组成、SEM(扫描电镜)观察和分析固体物质的表面形态和结构,并利用煅烧熟料配制静态破碎剂,给出了静态破碎剂的最优配比,研究了水灰比、环境温度以及拌和水温对静态破碎剂水化反应的影响。结果表明:随着煅烧温度的升高,碳酸钙分解成氧化钙的程度越高,氧化钙晶体收缩愈紧密,晶体微孔隙逐渐消失且变得越致密,表观密度增大,反应活性降低。静态破碎剂在测试钢管中的峰值温度随水灰比的增大先增大后减小;随环境温度以及拌和水温的升高而升高;但其温度随时间变化趋势大体一致。

2014第六届全国甲状腺肿瘤学术大会

Objective: The relationship between cervical lymphatic metastasis and TgAb is still not clear. This study is to investigate the relationship between positive TgAb and metastasis to cervical lymph nodes in Chinese population. Methods: A retrospective analysis was conducted on 595 consecutive patients who underwent thyroidectomy In Fujian Provincial Hospital between January and November in 2009. Ultrasonographic parameters, Serum concentrations of thyroglobulin antibodies（TgAb）, s-TSH and other molecular markers were measured before thyroidectomy. Surgical report confirmed the final outcome deciding a benign or malignant status. Results: There were 399 patients with benign thyroid nodules and 196 patients with malign thyroid nodules. Patients with malign nodules were likely to have smaller nodules（1.2±0.9 vs. 1.6±1.0 cm;p＜0.001）, higher levels of s-TSH（2.3±3.2 vs. 1.6±2.2 mIU/l;p=0.008）,lower HDL-C level（s1.3±0.3 vs. 1.4±0.4 mmol/L;p=0.017）,higher positive rate and levels of TgAb（5.9% vs. 20.6%, 6.8±12.2 vs. 16.0±22.1 mIU/L;both p＜0.001）. In the multivariate analysis, malignant nodule was associated with TgAb（OR=1.035,95%CI:1.018--1.052）, HDL-C（OR=0.323,95%CI:0.147--0.707）, lower sTSH level（OR=0.328, 95%CI: 0.118—0.916）, age, nodule size and nodule calcification. The prevalence of malignant cervical lymph nodules（MCLN） in the TgAb positive group was higher than the normal group（55.9 % vs. 44.2%, p for the trend=0.224）. Conclusion: Positive TgAb was associated with the thyroid cancer and a trend was demonstrated for the association with cervical lymph nodule metastasis in patients with thyroid cancer. There was a significant inverse association between HDL-C and the risk of thyroid cancer that is independent of LDL-C, TSH, age, sex.
