Objective To analysis and research the clinical pathological characteristics with papillary thyroid carcinoma(PTC)and nodular goiter.Methods 100 cases with thyroid disease were selected,the preoperative ultra-sound diagnosis and pathological diagnosis results were compared,and pathological features were analyzed.Results Ultrasound results:ther were 72 cases with PTC,and 28 cases with NG,and pathologically confirmed 48 cases with PTC,52 cases with NG.The difference of two diagnostic result was statistically significant (χ2 =5.263,P <0.05). Compared with 48 PTC cases,the ratio of single nodule in 52 NG patients was smaller,while multiple nodules and cystic lesions proportion were higher,the differences were statistically significant (χ2 =58.19,73.97,25.40,all P <0.05).PTC was characterized by solid nodules of gray matter,often located near the thyroid capsule.Large tumors may be cystic.NG was characterized by single or multiple nodules,with different size,and some nodules with incomplete capsule,some with thick fibrous capsule.Nodular cystic necrosis hemorrhage was common.Conclusion Ultrasound diagnosis and can make a more accurate judgment between NG and PTC,but there are still misdiagnosed on the two diseases,for PTC and NG accurate judgment also need to rely on pathological identification,so grasping the pathologi-cal features of both can improve diagnostic accuracy.

Objective To explore the competency of community health administrators in a survey of such administrators at large in Shanghai. Methods McClelland's Competency Dictionary was used to set two benchmark positions, while the behavioral event interviewing and questionnaires were made to survey 19 community health service centers in Shanghai. Results The competency model benchmarking on the head of a medical branch consists of 6 character clusters, 11 characteristic items, 27 evaluation dimensions and 27 typical behavior descriptions. The model benchmarking on the community team leader consists of 5 character clusters, 8 characteristic items, 21 evaluation dimensions and 21 typical behavior descriptions. Conclusion Findings of the survey provide objective criteria for competence appraisal of community health administrators, and serve as reference for formulating their development plans as well.

Insect antifreeze protein (AFP) has high antifreeze activity. Antifreeze proteins can be used in cryopreservation of biological tissues and cells. We expressed an antifreeze protein from the desert beetle Microdera punctipennis in yeast and determined the function of the protein at low temperatures. Yeast expression vector, pPIC9K-Mpafp698, was constructed and transformed into Pichia pastoris GS115. The expression of MpAFP698 was induced by methanol, and identified by tricine SDS-PAGE and Western blotting. Mpafp698 gene was inserted into the genome of the host yeast strain GS115, and correctly expressed. Hardly any yeast's own protein was secreted into the media. Cryoprotective experiments showed that MpAFP698 can significantly protect mouse liver as well as other mouse organs from cold damage compared with those in the control of Bovine serum albumin (BSA) addition. Besides, the hemolysis of blood cells protected by MpAFP698 at 4 degrees C was reduced and the survival rate of SF9 cells protected by MpAFP698 after freezing and thawing was increased compared to those of the control with BSA addition. Our results showed that MpAFP698 can be expressed in yeast, which allows a convenient purification of the MpAFP protein that has the cryoprotective effect.
