Objective To establish experimental autoimmune thyroiditis (EAT) rat model induced by bovine thyroglobulin (bTg) and to observe the effect of iodine on IP-10 in rat serum and IP-10 mRNA expression in rat thyroid tissue.Methods One hundred and thirty-five four-week old female Lewis rats were divided into normal control (NC,20 rats) group;TG group,25 rats;H Ⅰ group,20 rats;H Ⅰ + TG group,25 rats;H Ⅱ group,20 rats and H Ⅱ + TG group,25 rats according to a random number table.The water iodine concentration was 25.7 μg/L given to rats of HⅠ and H I + TG groups,and 423.3 μg/L of H Ⅱ and H Ⅱ + TG groups.Rats of NC and TG groups drank distilled water.Rats of TG,H Ⅰ + TG,H Ⅱ + TG groups were immunized with 0.1 ml bTg (8 g/L) in IFA.All rats were killed at the end of 15 weeks.Urinary iodine was determined by As3+-Ce4+ catalytic spectrophotometry (WS/T 107-2006).Pathological changes in thyroid tissue were observed by light microscope.Serum IP-10 was determined by enzyme-linked immunosorbent assay (ELISA),and IP-10 mRNA expression in thyroid was detected by real-time PCR.Results The differences of urinary iodine between groups were statistically significant (x2 =106.4,P ＜ 0.05).Compared with NC group (456.45 μg/L) urinary iodine in other groups increased significantly (TG,H Ⅰ,H Ⅰ + TG,HⅡ,HⅡ + TG:800.08,18 633.20,13 869.08,87 889.97,61 661.51 μg/L,all P ＜ 0.05).The pathological changes of rats in each group aggravated following increased iodine intake,NC group had normal thyroid structure;thyroid of TG group had a small amount of lymphocytes;thyroid of H Ⅰ group showed irregular follicular,part of the follicular was destroyed;a large number of lymphocytes infiltrated between follicular of H Ⅱ group;in H Ⅱ + TG group,the follicular was destroyed severely,diffuse inflammatory cell infiltration.The difference of serum IP-10 between groups no were statistically significant (F =1.462,P ＞ 0.05).The expression of IP-10 mRNA of H Ⅰ + TG (2.80 ± 1.73) rats thyroid was higher than that in NC (1.65 ± 1.62) and H Ⅰ (1.07 ± 1.00) groups,H Ⅱ (0.64 ± 0.64),H Ⅱ + TG (0.80 ± 0.49) were lower than H Ⅰ + TG group (all P ＜ 0.05).Conclusions Excessive iodine intake could have increased inflammatory cells in EAT rat and rats have showed more serious pathologic changes.These phenomena may be ralated with changed expression of IP-10 mRNA in EAT rat thyroid.

Objective To transform knowledge organization systems (KOS) about traditional Chinese medicine (TCM) domain into standardized ontologies, in order to achieve the publication, sharing, and fusion of TCM KOS on the Web, and to further improve the organization and management of TCM knowledge. Methods Simple knowledge organization system (SKOS), a technical specification recommended by World Wide Web Consortium, was used to transform TCM KOS into publishable ontologies on the Web. Results Traditional Chinese medicine language system was transformed into an SKOS ontology, which was stored into a knowledge base that could support SPARQL (standard query language of the Semantic Web) query access, and provide concept, terminology, and knowledge services for Semantic Web applications, such as semantic wiki and semantic search via Web service interfaces. Conclusion This research preliminarily verifies the applicability of SKOS in TCM domain, and exemplifies the process of transforming TCM KOS into SKOS ontologies.

Objective To study the relationship between macular pigment optical density (MPOD) and serum concentration of lutein and zeaxanthin in an adult population.Methods Twenty patients with mild cataract and 39 healthy subjects were enrolled in this study,including 15 males and 44 females.The average age was 43.75 years.Fifty-three subjects were non-smokers and 6 male subjects were smokers.Two subjects preferred meat diet,22 preferred meat-less diet,and 35 have balanced diet.MPOD was measured using heterochromatic flicker photometry at 0.25,0.5,1.0 and 1.75 degrees,and serum concentration of lutein and zeaxanthin was measured using high-performance liquid chromatography.The relationship between MPOD and serum concentration of lutein and zeaxanthin was analyzed.The differences of serum lutein and zeaxanthin between different gender,smokers and non-smokers and subjects with different dietary pattern were also analyzed.Results MPOD at 0.25,0.5,1.0 and 1.75 degrees were 0.59,0.48,0.34 and 0.18,and the average concentration of lutein and zeaxanthin were (0.45± 0.16) μmol/L and (0.11 ± 0.04) μmol/L respectively.Serum concentration of lutein and zeaxanthin in males were slightly higher than that in females,but it was not statistically significant (t=1.13,0.86;P=0.27,0.40).The differences of serum lutien and zeaxanthin between smokers and non-smokers (t=0.15,-0.11;P=0.87,0.91),among subjects of 3 dietary patterns groups were not statistically significant (Flutein=3.87,4.05,0.18;P=0.83,0.81,0.99.Fxeaxanbin=0.99,1.51,0.52;P=0.85,0.68,0.72).There was no correlation between MPOD and serum concentration of lutein (r=-0.06,-0.02,-0.07,0.03;P＞0.05) and zeaxanthin(r=0.02,0.12,0.09,0.11;P＞0.05).Conclusion MPOD was not statistically significantly correlated with serum concentration of lutein and zeaxanthin in the studied population.

All elements and refinements had been built in ontology with protégé 4.1, which can be used to record over 20 classic Chinese medicine books in related author, publisher, storage site, edition, form and arrangement of lines in calligraphy, and etc. It also realized the graphical display based on ontology. It gave brief analysis on elements which had been used or without using. Studies showed that Web Ontology Language (OWL) can express all elements of TCM literatures clearly. This study indicated that element refinements should be considered to add in the amendment of ISO International Standards application for further improvement.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

To explore the therapeutic effect of micro-traumatic surgery of loose seton and cutting seton by rubber bands in the treatment of high anorectal fistulae.Application of cutting seton (truss rubber bands) implemented the high part of fistulae and loose seton (ligation rubber band but non-fastened) for the low part of fistulae.133/136 patients undergoing micro-traumatic surgery were cured by one operation,2 cases had pseudo-healing and there was 1 recurrent case.And the curative rate was 97.8％.The microtraumatic surgery of loose seton and cutting seton by rubber bands in the treatment of high anorectal fistula has such multiple advantages as small incision,minor trauma,lesser pain,faster healing and a shorter course of treatment.And it may preserve the proper anal function and the integrity of anal skin.And its clinical efficacy is satisfactory.

Objective To investigate the diagnosis and treatment of idiopathic chronic colonic pseudo-obstruction(ICCPO). MethodsIn this study 69 patients admitted for “constipation” were finally found falling into one of the 4 groups: 11 cases of outlet obstructive constipation, 16 cases of slow transit constipation, 26 cases of mixed type, and 16 of ICCPO. ResultsThe main symptoms of these 16 ICCPO cases were intractable constipation, compared with that in other entities ICCPO tends to affect patients at younger age, with shorter clinical course, and often needs surgical intervention due to intractable bowel obstruction, usually total colectomy. ConclusionsICCPO, STC and mixed constipation are different clinical entities. The differentiation of ICCPO from other entities is sometimes very difficult especially when patients are suffering from acute onset of bowel obstruction.

Objective To study the anatomic data of the first metatarsal dorsal artery and to provide anatomical basis for clinical tissue transplantation based on the first metatarsal dorsal artery.Methods The 16 adult cadaver specimens with 32 feet were dissected and meas-ured by vernier caliper.Then the anatomic data of the first metatarsal dorsal artery were analyzed.Results Through the examinations of 32 feet sample,the first metatarsal dorsal artery were classified into 5 types.Type Ⅰ:the first metatarsal dorsal artery runs at the surface of the first dorsal interosseous muscle (13 sides,40.6%).Type Ⅱ:the first metatarsal dorsal artery runs in the interior of the first dorsal interosse-ous muscle (11sides,34.4%).Type Ⅲ:the first metatarsal dorsal artery runs underneath the first dorsal interosseous muscle (6 sides, 18.8%).Type Ⅳ:the first metatarsal dorsal artery is slender (1 side,3.1%).TypeⅤ:the first metatarsal dorsal artery is absent (1 side, 3.1%).Distance relationship was measured between the first metatarsal bone and the first metatarsal dorsal artery:the vertical distance be-tween the origin of the posterior branch of the first metatarsal dorsal artery and base of the first metatarsal bone was (2.4 ±0.3)mm,the ver-tical distance between the origin of the posterior branch of the first metatarsal dorsal artery and head of the first metatarsal bone was (10.1 ±1.0)mm;the vertical distance between the origin of the anterior branch of the first metatarsal dorsal artery and the first metatarso-phalangeal joint was (7.6 ±2.7)mm.Conclusion The first metatarsal dorsal artery has clinical reference significance for the hands and feet’s trauma and skin flap transplantation such as thumb reconstruction.

Autophagy dysregulation, mitochondrial dynamic abnormality and cell cycle re-entry are implicated in the vulnerable neurons of patients with Alzheimer's disease. This study was designed to testify the association among autophagy, mitochondrial dynamics and cell cycle in dividing neuroblastoma (N2a) cells. The N2a cells were cultured in vitro and treated with different concentrations of 3-methyladenine (3-MA). The cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay. They were randomly divided into control group (cells cultured in normal culture medium) and 3-MA group (cells treated with 10 mmol/L 3-MA). The cell cycle was analyzed in the two groups 3, 6, 12, and 24 h after treatment by flow cytometry. Western blotting was used to evaluate the expression levels of mitofission 1 (Fis1), mitofusin 2 (Mfn2), microtubule-associated protein 1 light chain 3 (LC3), cell cycle-dependent kinase 4 (CDK4) and cdc2. The flow cytometry revealed that the proportion of cells in G(2)/M was significantly increased, and that in G0/G1 was significantly reduced in the 3-MA group as compared with the control group. Western blotting showed that the expression levels of Fis1, LC3, and CDK4 were significantly up-regulated in the 3-MA group at the four indicated time points as compared with the control group. Mfn2 was initially decreased in the 3-MA group, and then significantly increased at 6 h or 12 h. Cdc2 was significantly increased in the 3-MA group at 3 h and 6 h, and then dropped significantly at 12 h and 24 h. Our data indicated that 3-MA-induced suppressed autophagy may interfere with the cell cycle progression and mitochondrial dynamics, and cause cell death. There are interactions among cell cycle, mitochondrial dynamics and autophagy in neurons.
