In recent years,morbidity of thyroid carcinoma is rising,but its mortality decreased because of the standardized diagnosis and treatment.Pecially to the development and improvement of the surgical treatment.In this field,there has not reached the common understanding at present.In this article we review the extent of surgery,re-operation of the thyroid carcinoma,neck lymph dissection,131I ablation and thyroid hormone suppression therapy.

OBJECTIVE:To establish fingerprint of Zhizi jinhua pills(ZZJHW)and analyze the relationship of it with in vitro antioxidant activity,in order to provide the basis for the quality control of them. METHODS:HPLC method was adopted. The sep-aration was performed on a Sinochrom ODS-BP C18(200 mm×4.6 mm,5 μm)column with mobile phase consisted of 0.2% acetic acid(containing 3 mmol/L sodium heptanesulfonate solution)-acetonitrile(gradient elution)at the detection wavelength of 254 nm and flow rate of 0.8 ml/min. The column temperature was controlled at 38 ℃,and injection volume was 10 μl. The“Chromato-graphic Fingerprint Similarity Evaluation System for TCM”(2012.130723 edition) issued by Chinese Pharmacopoeia Commission was used to evaluate the similarity of the 12 batches of ZZJHW using baicalin as reference peak so as to attribute the common peak of fingerprint. DPPH free radical scavenging assay was used to investigate the in vitro antioxidant activity of 12 batches of ZZJHW,and the relationship between its fingerprint and antioxidant activity was studied. RESULTS:The fingerprint of 12 batches of ZZJHW was established and the similarity between the fingerprint of ZZJHW with their reference fingerprint were all above 0.9 (except S1,S2,S3,S12). 30 common peaks were marked,all of which were assigned to the herbs. Antioxidant experiment result showed the differences in the antioxidant capacity among different batches of ZZJHW;spectrum effect relationship showed that 13 common peaks were positively related with oxidation activity and 17 common peaks negatively related with it;among known com-ponents,oxidation activity components were mainly from Lonicera japonica,Scutellaria baicalensis and Rheum palmatum. CON-CLUSIONS:The spectrum effect relationship of established fingerprint with its antioxidant activity can provide reference for the quality control of ZZJHW.

Objectives: To explore the expression regulation of type 1 and type 2 (Th1 and Th2) cytokines from serum of coal miners and the evaluation in surveillance of coal workers' pneumoconiosis, 630 coal miners were studied. Methods: A total of 90 male patients diagnosed as coal workers' pneumoconiosis (CWP) in a institute for occupational health and 19 male workers newly diagnosed as CWP patients was chosen as CWP group with simple random sampling method from a coal mine group from January 2013 to December in 2015. 180 male coal miners with abnormal but not diagnosed as CWP were selected as CWP suspected group with simple random sampling methods, meanwhile 180 male coal miners with normal chest X-ray photograph was as dust-exposed group by 1∶1 matched as age. And 161 healthy males accepted pre-employed examination were selected as control group, CWP suspected group, dust-exposed group and control group called as non-CWP group. According to screening test and diagnosis test, the basic information and occupational history of all subjects were collected, and cytokines including IL-1β, IL-8, IFN-γ, IL-6 and IL-10 of serum were detected. Receiver operator characteristic (ROC) curve was used to determine the optimal cutoff value of each cytokine. Area under curve (AUC), the validity and reliability were calculated and judged. Results: The average age of control group, dust-exposed group, CWP suspected group and CWP group were (27.4±5.0) , (43.4±10.7) , (48.2±6.2) , (64.7±7.0) years old, respectively. The median level of IL-1β, IL-8, IFN-γ and IL-6 in cases group (1 638.30, 2 099.49, 815.18,140.32 pg/ml) were higher than that of non-cases group (1 445.57, 1 402.26, 736.38, 95.73 pg/ml) (P<0.05) . The level of IL-8 (1 503.99 pg/ml) in CWP suspected group was higher than that of control group (1 295.67 pg/ml) and dust-exposed group (1 376.94 pg/ml) , but the level of IL-10 (654.08 pg/ml) was lower than that of control group (596.64 pg/ml) . The ratio of IFN-γ/IL-6 ranged from 5 to 8, and the ratio in CWP group (5.87) was lower than that of non-CWP group (7.61) . The IL-6 and IL-8 among the subjects of dust-exposed group in terms of the age distribution of among had reached statistical significance. According to ROC, the cutoff value of IL-1β, IL-6, IL-8, IL-10 and INF-γ reached 1 582.65, 116.53, 1 791.54, 581.08 and 792.69 pg/ml, respectively. The AUC was 0.668, 0.895, 0.859, 0.716 and 0.637, respectively. It was found that IL-6 and IL-8 could be used as biomarkers in detecting CWP, the sensitivity and specificity was 82.6% and 84.6%, 78.0% and 84.8%, respectively; Youden's index was 0.674 and 0.628 and the consistency rate was 84.3% and 83.7%, while Kappa value was 0.55 and 0.52. Conclusion There was Type 1 and type 2 cytokine dysregulation in CWP patients. IL-6 and IL-8 can be used as effective biomarkers to forecast lung injury before X-ray changes.
