Objective To investigate the clinical efficacy and ultrasonographic changes treated with anti-thyroid drugs ( ATD ) in patients with primary hyperthyroidism(PHT).Methods 83 cases of PHT patients admitted to the department of ultrasound from February 2013 to August 2015 in Zhuji People's Hospital of Zhejiang Province were selected, the patients were divided into two groups according to the results of ultrasonography, echo nonuniform group 41 cases and echo uniform group 42 cases.ATD therapy was administered to the both groups (were treated with methimazole).The thyroid related indexes and hemodynamics of thyroid right superior diagnosed by color doppler ultrasound, and the curative efficacies of the two groups were analyzed.Results After treatment, the systemic vascular resistance index(RI) of echo uniform group was (0.62 ±0.17), and the echo nonuniform group was (0.65 ±0.18), there was no significant difference between the two groups.The echo uniform group of thyroid artery diameter on the right lobe(D), the peak systolic velocity(Vmax), minimum diastolic blood flow velocity(Vmin), thyroid volume(V) and blood flow volume(Q) were significantly lower than the echo nonuniform group, the difference was statistically significant (P <0.05).The total effective rate of the echo nonuniform group (48.78%) was significantly lower than that in the echo uniform group (85.71%), the difference was statistically significant(P <0.05).Conclusion ATD has a good effect in treating PHT, and can significantly improve the thyroid hemodynamics in patients, it has a positive effect on the regulation of thyroid-related parameters in patients, the clinical treatment is effective, and the effect is better especially in patients with uniform echo.

Objective To study the benzylphenethylamine alkaloids from the bulbs and flowers of Lycoris radiata.Methods Alkaloids were isolated by various column chromatographic methods and their structures were identified by spectral data.Results Fifteen known benzylphenethylamine alkaloids were isolated and identified as lycoramine(1),O-demethyllycoramine(2),N-demethyllycoramine(3),galanthamine(4),lycorine(5),caranine(6),ungminorine(7),narciclasine(8),5-hydroxy-10-O-demethyl-homolycorine(9),hippeastrine(10),ungerine(11),hippeastrine N-oxide(12),O-demethylhaemanthamine(13),haemanthidine(14),and 8-demethoxybostasine(15).Conclusion Compound 15 is first isolated from the plants in Amaryllidaceae,compounds 3,6,9,and 11 are first reported from the plants in Lycoris Herb.,and compounds 2,7,and 14 are isolated from L.radiata for the fast time.The 13C-NMR data of compouds 3,7,and 12 are first reported in the present study.Furthermore,the galasine-type alkaloid is isolated from the plants of Lycoris Herb.for the first time.

Objective To study the relationship between social support and subjective well-being(SWB) of labor workers.Methods 1038 labor workers in Shenzhen were evaluated by subjective well-being scale for Chinese citizen (SWBS-CC), social support rating scale ( SSRS ).Results There was no significant difference in SWB between male and female( ( 63.51 ± 11.03 ) vs ( 63.22 ± 12.02 ), t = 0.389, P ＞ 0.05 ).The 30 ～ 49 age group's score was significantly higher than the 16 ～29 age group's( (62.80 ± 11.80) vs (64.54 ± 11.28), t=2.21, P ＜ 0.05 ).The married group's score was significantly higher than the unmarried group's ( (62.50 ± 12.18)vs (64.27 ± 10.80 ), t= 2.44, P ＜ 0.05 ).Social support was significant positively correlative with subjective well-being ( r=0.075 ～0.391, P＜0.05), except support availability was not correlative with both subscales.Subjective support, support availability and objective support were significantly positive predictions of SWB, meanwhile subjective support was the biggest( β =0.297).Conclusion Subjective well-being of the labor workers in Shenzhen have significant relationship with age and social support.To increase the emotional support for the labor workers could possibly help to improve their subjective well-being.
