Analysis of Animal Models of Hyperthyroidism Based on Characteristics of Clinical Symptoms of Traditional Chinese and Western Medicine / 中国实验方剂学杂志

Hyperthyroidism is a systemic disease characterized by clinical signs and symptoms of hypermetabolism and sympathetic nervous excitement. Based on the clinical diagnostic criteria of traditional Chinese and western medicine for hyperthyroidism，the present study summarized and evaluated animal models of hyperthyroidism. In model evaluation，the models with high coincidence degree in western medicine included the exogenous drug delivery model， the model immune to adenovirus expressing thyrotropin receptor （TSHR），the model immune to nucleic acid， and the model of yin deficiency and effulgent fire syndrome in the disease-syndrome combination. The models with high coincidence degrees in traditional Chinese medicine included the exogenous drug delivery model， the model immune to adenovirus expressing TSHR，and the model of liver-yang ascendant hyperactivity syndrome and the model of yin deficiency and effulgent fire syndrome in the disease-syndrome combination. In light of the coincidence degree， and advantages and disadvantages of traditional Chinese and western medicine，the ideal hyperthyroidism animal models are the exogenous drug delivery model， and the model immune to adenovirus expressing TSHR. In addition to the evaluation of the coincidence degree of animal models of hyperthyroidism in traditional Chinese and western medicine，this study also analyzed the advantages，disadvantages， and problems of the animal models of hyperthyroidism. Most of the animal models of hyperthyroidism were not consistent with the complexity of hyperthyroidism in clinical practice， and standardized and unified syndrome differentiation standards and four-examination information collection standards have not yet been formed. Besides， there have been few studies on the hyperthyroidism model in disease-syndrome combination in traditional Chinese medicine. To make the animal models of hyperthyroidism suitable for clinical practice，the present study proposed the improvement directions of animal models of hyperthyroidism and the necessity of promoting the evaluation system to provide a theoretical basis for the evaluation of the curative effect of Chinese medicine on hyperthyroidism， and exploration of its pharmacological action， as well as the follow-up research on the pathogenesis，prevention， and treatment of hyperthyroidism，which is expected to establish a perfect disease-syndrome model of hyperthyroidism in line with clinical characteristics of traditional Chinese and western medicine.

Analysis of animal models of stable chronic obstructive pulmonary disease based on clinical features of traditional Chinese medicine and western medicine / 中国中药杂志

This study analyzed the advantages and disadvantages of existing animal models in China and abroad and their goodness of fit based on the clinical characteristics and diagnostic criteria of stable chronic obstructive pulmonary disease(COPD) in traditional Chinese medicine(TCM) and western medicine, followed by the collation and summarization of model evaluation methodologies. The results showed that the existing animal models of stable COPD were mainly modeled via smoke exposure or the combination of multiple methods like smoke exposure plus lipopolysaccharide or protease or bacterial infection. These animal models generally failed to simulate the clinical characteristics of TCM, and their goodness of fit in western medicine was higher than that in TCM. There is a lack of research on the animal models of stable COPD and the disease-syndrome combination models. Although the modeling is guided by the pathogenesis or mechanism of diseased humans, the established models were still not identical with the actual clinical situations. In-depth research is needed to develop quantitative standards for stable COPD models.

Clinical research progress on high mobility group protein box 1 / 中国小儿急救医学

High mobility group protein box 1 (HMGB1) is a highly conserved DNA binding protein, which is found in the nucleus of a variety of cells in the body, regulating the transcription of cell genes.It plays a role of nuclear binding protein in physiological state.Once released into the cell gap, it performances the role of inflammatory mediators.Recent studies showed that pathogenesis of HMGB1 not only involved in sepsis, autoimmune diseases, chronic liver disease, malignant tumor, but also involved in cell injury repair,which plays important role in a variety of diseases, organ damage, repair process.

Research Progress in Citrulline and Related Diseases / 沈阳医学院学报

Citrulline which is a nonprotein amino acid,synthesizes the peptide bond,but it is not incorporated into proteins. It's used to be known as no point, but there is a difficult result that citrulline is related to many diseases in recent research.Citrulline is a biomaker in gastrointestinal injury,a supplement of arginine in arginine deficiency patients,and the evidence of sepsis.Citrulline,as an antigen among the process of its creation ,is one of the nosogenesis of rheumatoid arthritis,and checking the antibodies of citrulline is effective in diagnosing the rheumatoid arthritis early. Citrulline is also meaningful in diagnosing and treatment of some unfrequent diseases. Citrulline is widely used.

Comparative study between clinical disease activity index and simplified disease activity index by assessing the activity of rheumatoid arthritis / 中华风湿病学杂志

ObjectiveTo compare the clinical disease activity index (CDAI) and simplified disease activity index(SDAI) as well as disease activity score 28(DAS28) by assessing the activity of rheumatoid arthritis (RA) and to explore which one is better.MethodsTwo hundred RA patients were enrolled.Swelling joint counts (SJC),tenderness joint counts(TJC ),patient's and doctor's global assessment of disease activity based on visual analogue scale(PGA,PhGA),health assessment questionnaire(HAQ) were recorded and the erythrocyte sedimentation rate(ESR),C reaction protein (CRP) of each patient were tested.DAS28,CDAI,SDAI of all patients were calculated for all patients.Statistical analysiswas carried out by Pearson correlation for the association between DAS28 and the above parameters,as well as CDAI,and SDAI.We created 4 patient groups based on DAS28,CDAI and SDAI ranks and used kappa statistics to assess the level of overall agreement of different disease activity categories between any of the two indices above for individual patients.We assessed the discriminating validity using receiver operating characteristic(ROC) curve analysis to compare the ability of the CDAI and SDAI to discriminate betwecn patients with remission, low and moderate,high disease activity.ResultsOf all the patients,CDAI(17.2±11.1) and SDA[(19.1±11.6) were correlated with DAS28 (4.3±1.5),the correlation coefficients were 0.876,0.861 (P＜0.05) respectively.CDAI and SDAI were correlated with HAQ (0.6±0.7),as well as DAS28.The correlation coefficients were 0.522,0.523,and 0.482(P＜0.05).The Kappa of CDAI and SDAI was 0.777.The Kappa of CDAI and DAS28,SDAI and DAS28 were 0.482,0.394.The areas under ROC of CDAI and SDAI were 0.906,0.888 if DAS28 was used as the gold standard.ConclusionCDAI and SDAI as well as DAS28 can be used to assess the activity of RA and both are better correlated with HAQ than DAS28.Though there is no CRP in CDAI when compared with SDAI,CDAI has very goodoverall agreement with SDAI and the overall agreement of CDAI and DAS28 is better than SDAI and DAS28.In addition, CDAI is better in discriminating between patients with remission/low and moderate/high disease activity.So,CDAI is a simple,convenient,accurate,quick assessment tool and is suitable for daily application.

Anti-endothelial cell antibodies and central nervous system involvement in Behçet's disease

INTRODUCTION: Previous studies have detected the presence of anti-endothelial cell antibodies (AECA) in patients with Behçet's disease (BD). However, no real evidence exists whether these antibodies exert any influence on clinical presentation and/or activity of this disease. OBJECTIVES: To determine the frequency of AECA in patients with BD and analyze possible clinical associations. METHODS: 50 patients with BD who fulfilled diagnostic criteria were selected. Thirty-seven patients were females, and 13 were males; the mean age was 44 ± 9 years with a mean follow-up time of 10 ± 7.5 years. AECA were assayed by ELISA using ECV-304 cells as the antigenic substrate. The prevalence of AECA was determined, and their possible relationships with present and past clinical features were investigated. RESULTS: AECA were detected in the sera of 38 percent of the patients (IgG in 13, IgM in four, and IgG plus IgM in two). An association was observed between AECA and a previous history of central nervous system involvement (OR= 5.4, p= 0.03). This association was more evident for IgG-AECA (OR= 6.0, p= 0.02). A trend of an increased risk of aneurysms was also observed in patients with IgG-AECA (OR= 2.58, p= 0.77). None of the other clinical characteristics showed a relevant association with these antibodies. CONCLUSION: Our data suggest that IgG-AECA may be a marker of more severe lesions in patients with BD based on the higher frequency of previous central nervous system manifestations in patients who presently display circulating AECA.

INTRODUÇÃO: Estudos anteriores detectaram a presence de anticorpos anti-célula endotelial (AACE) em pacientes com doença de Behçet, porém não há nenhuma evidência se a presença destes anticorpos exerce alguma influência na apresentação clínica ou atividade da doença. OBJETIVOS: Determinar a freqüência de AACE em pacientes com doença de Behçet e analisar possíveis associações clínicas. MÉTODOS: Foram selecionados 50 pacientes que preencheram corretamente os critérios diagnósticos para a doença de Behçet. Trinta e sete pacientes eram do sexo feminino e 13 do sexo masculino, média de idade de 44 ± 9 anos e tempo médio de seguimento de 10 ± 7,5 anos. O AACE foram analisados por ELISA utilizando células ECV-304 como substrato antigênico. A prevalência de AACE foi determinada e foram investigadas possíveis relações com características clínicas atuais e pregressas. RESULTADOS: Os AACE foram detectados no soro de 38 por cento dos pacientes (13 na forma IgG, 4 IgM e 2 nas formas IgG e IgM). Observamos uma associação entre o AACE e história pregressa de envolvimento de sistema nervoso central (OR=5,4; p=0,03). Esta associação era mais evidente para o AACE na forma IgG (OR=6,0; p=0,02). Observamos também uma tendência de risco aumentado de aneurismas em pacientes com AACE na forma IgG (OR=2,58; p=0,77). Nenhuma outra característica clínica mostrou-se relevante com o anticorpo estudado. CONCLUSÃO: Nossos dados sugerem que o AACE na forma IgG pode ser uma marcador de lesão mais grave em pacientes com doença de Behçet baseado no fato de encontrarmos uma maior freqüência de história pregressa de manifestação de sistema nervoso central em pacientes com AACE circulante.

Correlation of serum interleukin 8 with clinical disease activity in systemic lupus erythematosus (SLE) / 대한내과학회지

OBJECTIVES: To evaluate serum Interleukin 8 (IL-8) as a predictor of disease activity in SLE and to provide insight into the potential role of IL-8 in the pathogenesis of SLE. METHODS: Sixty-four paired sera from the 32 SLE patients and 10 healthy control sera were obtained. Serum IL-8 levels were determined by ELISA technique. Tests for other laboratory parameters, such as circulating immune complex (CIC), C3, C4, ANA, anti-dsDNA, Hb, Hct, leukocyte, lymphocyte, platelet and ESR, were performed for every sample coincidently with assessment of clinical disease activity by the Lahita scales. RESULTS: We found that serum IL-8 levels in SLE patients were significantly higher than those of healthy controls. Serum IL-8 levels significantly correlated with clinical disease activity. Serum IL-8 levels correlated with CIC, but it had no correlation with other laboratory parameters. CONCLUSON: These findings suggest that serum IL-8 can be used as a marker of disease activity in patients with SLE. These results may have implication in the pathogenesis of SLE.
