RESUMO
Objective To investigate the clinical significance of monitoring the serum levels of Thyroglobulin (Tg) and Thyroglobulin Autoantibody (TgAb) in the 131I ablation therapy for patients with differentiated thyroidcarcinoma (DTC).Methods 102 patients with DTC treated by 131I ablation therapy in our hospital from May 2014 to July 2016 were selected.The serum levels of Tg and TgAb were detected by radioimmunoassay before 131I ablation therapy,6 months after I 13 1I ablation therapy and 12 months after 131I ablation therapy.The body imaging were performed at seventh days after 1311 ablation therapy.Results The serum levels of Tg and TgAb at 6 months and 12 months after surgery were significantly lower than those before operation,and the difference were statistically significant (t =9.260,17.507,2.534,4.797,P ＜ 0.05).The serum levels of Tg and TgAb in metastasis group were higher than that in non-metastasis group (t =10.257,7.353,P ＜0.05).The serum levels of Tg and TgAb in the effective group were lower than those in the ineffective group,and the difference were statistically significant (t =7.325,4.978,P ＜ 0.05).The positive rate of Tg combined with TgAb was similar with 131I-WBS screening methods and the difference was not statistically significant (P ＞ 0.05).The positive rate of Tg screening method and the positive rate of TgAb were higher than that of 131I-WBS screening method,but the difference was not statistically significant (P ＞ 0.05).Conclusions The level of serum Tg and TgAb is an important reference index for the efficacy,metastasis and recurrence of DTC after operation,and Tg combined with TgAb has a higher accuracy in the screening prognosis of DTC after operation.
RESUMO
Objective To explore the correlation between the levels of liver fibrosis and liver fibrosis biochemical parameters of advanced schistosomiasis patients. Methods A total of 48 advanced schistosomiasis patients were investigated and they were examined by the liver biopsy and B ultrasound imaging. At the same time,the liver fibrosis biochemical parameters,including glu-tamine transpeptidase(GGT),alkaline phosphatase(AKP),procollagenⅢ(PC-Ⅲ),collagen typeⅣ(Ⅳ-C),hyaluronic acid (HA)and laminin(LN),were detected. The liver fibrosis levels were classified by the liver biopsy and B ultrasound imaging,re-spectively,and the correlation between the levels of liver fibrosis and liver fibrosis biochemical parameters were analyzed statisti-cally. Results There was no correlation between the liver fibrosis levels classified by the liver biopsy and all the liver fibrosis bio-chemical parameters;there was a weak correlation between the liver fibrosis levels classified by the B ultrasound imaging and GGT,AKP,LN and PC-Ⅲ,respectively;there was a significant correlation between the liver fibrosis levels classified by the B ul-trasound imaging and HA andⅣ-C,respectively. Conclusions B ultrasound examination is a better,noninvasive fibrosis in-spection method. Liver fibrosis biochemical parameters combined with the B ultrasound examination may better reflect the overall condition of liver fibrosis.
