M2 polarization of monocytes in ankylosing spondylitis and relationship with inflammation and structural damage

The aim of this study was to evaluate the polarization of peripheral blood monocytes in the patients with ankylosing spondylitis (AS) and to determine the correlations between monocyte polarization and inflammation and structural damage. A total of 120 AS patients, 50 rheumatoid arthritis (RA) patients and 100 healthy controls were enrolled in the study. M1 (CD68+CD192+) and M2 (CX3CR1+CD163+) monocytes were characterized by flow cytometry. Demographic, clinical, radiographic and laboratory data were collected and analyzed. A large increase in M2 (CX3CR1+CD163+) monocytes was observed in AS, and M2/M1 ratio was 7.18 ± 6.12, 2.54 ± 3.14 and 35.61 ± 20.04 in control, RA and AS, respectively. The M2/M1 ratio correlated with modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) (r = 0.565; p < 0.001), ESR (r = ?0.321; p < 0.001, CRP (r = ?0.265; p < 0.001) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) (r = ?0.201; p = 0.028). Anti‐TNF‐α therapy induced a significant reduction in the percentage of M1 monocyte, ESR, CRP and BASDAI in AS patients. The present results demonstrated that M2 type polarized monocytes are predominant in the peripheral blood in AS and the M2/M1 ratio is correlated with structural damage (mSASSS), inflammatory biomarkers (ESR and CRP) and BASDAI.     

Trend of non-communicable disease mortality for three common conditions in the elderly population from 2002 to 2010: A population-based study in China

ObjectiveThere is a lack of data focusing on non-communicable disease (NCD) mortality in the Chinese elderly population over the past decade.MethodsUsing mortality data from the Chinese Health Statistics, we explored the crude and age-standardized mortality trend of three major NCDs in the Chinese population ≥65 years of age from 2002 to 2010, namely, malignant neoplasms, heart diseases, and cerebrovascular diseases. Subpopulations characterized as rural and urban residence, and by gender and age were examined separately.ResultsMortality increased with age and was higher among males than among females across the three NCDs, with the gender difference being most remarkable for malignant neoplasms and least for heart diseases mortality. Condition-specific crude mortalities increased between 2002 and 2010, overall and in all the pre-specified subpopulations. After age-standardization, rising trends were observed for people ≥65 years old, and condition-specific mortalities generally increased in rural regions and decreased in urban regions, especially for cerebrovascular diseases.ConclusionsThere were increasing trends for mortality due to malignant neoplasms, heart diseases, and cerebrovascular diseases in China between 2002 and 2010, which were largely driven by the population aging. Disparities existed by rural and urban residence, gender, and age.     

Stem cell transplantation for treating Duchenne muscular dystrophy A Web of Science-based literature analysis

OBJECTIVE: To identify global research trends in stem cell transplantation for treating Duchenne muscular dystrophy using a bibliometric analysis of Web of Science. DATA RETRIEVAL: We performed a bibliometric analysis of studies on stem cell transplantation for treating Duchenne muscular dystrophy from 2002 to 2011 retrieved from Web of Science. SELECTION CRITERIA: Inclusion criteria: (a) peer-reviewed published articles on stem cell transplantation for treating Duchenne muscular dystrophy indexed in Web of Science; (b) original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and (c) publication between 2002 and 2011. Exclusion criteria: (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) corrected papers. MAIN OUTCOME MEASURES: (1) Annual publication output; (2) distribution according to subject areas; (3) distribution according to journals; (4) distribution according to country; (5) distribution according to institution; (6) distribution according to institution in China; (7) distribution according to institution that cooperated with Chinese institutions; (8) top-cited articles from 2002 to 2006; (9) top-cited articles from 2007 to 2011. RESULTS: A total of 318 publications on stem cell transplantation for treating Duchenne muscular dystrophy were retrieved from Web of Science from 2002 to 2011, of which almost half derived from American authors and institutes. The number of publications has gradually increased over the past 10 years. Most papers appeared in journals with a focus on gene and molecular research, such as Molecular Therapy, Neuromuscular Disorders, and PLoS One. The 10 most-cited papers from 2002 to 2006 were mostly about different kinds of stem cell transplantation for muscle regeneration, while the 10 most-cited papers from 2007 to 2011 were mostly about new techniques of stem cell transplantation for treating Duchenne muscular dystrophy. CONCLUSION: The publications on stem cell transplantation for treating Duchenne muscular dystrophy were relatively few. It also needs more research to confirm that stem cell therapy is a reliable treatment for Duchenne muscular dystrophy.     

学生标准化病人在内科护理学客观结构化临床考试中的应用

目的了解内科护理学客观结构化临床考试（OSCE）中学生标准化病人（SSP）的模拟水平，分析SSP在模拟病人方面存在的问题，从而为进一步改进SSP提供依据。方法自行设计问卷，以我院参加内科护理学出科考试的74名学生作为调查对象，评价SSP的模拟水平。结果学生对SSP模拟病人逼真程度评价总分为（15．69±1．951）分，其中SPP能自然地回答学生提出的问题评价评价得分为（3．24±0．463）分。所有学生均认为运用SSP考核学生的临床能力是有效的，97％学生认为与传统考试模式相比标准化病人考核模式更能真实地反映学生的临床实际水平。结论培训护理专业学生为sP用于内科护理学OSCE考试可行性好，但需要进一步采取措施提高SSP模拟体征的逼真程度及各站SSP表演的协调一致性程度。     

Increase of toll-like receptor 4 but decrease of interleukin-8 mRNA expression among ischemic stroke patients under aspirin treatment

ObjectivesToll-like receptors (TLRs) are molecules conserved in evolution for detecting pathogen invasions and tissue damage and are involved in atherogenesis. This study explores the mRNA expression of TLRs and their probable role in further disease occurrence among ischemic stroke patients.Design and MethodsA total of 89 ischemic stroke patients and 166 controls were recruited for this study. Total RNA was extracted and mRNA was reverse-transcribed to cDNA and was analyzed for TLRs and interleukin 8 (IL8).ResultsThe TLR4 mRNA expression level is significantly higher in the stroke group. Conversely, IL-8 mRNA levels decreased significantly in the patient group.ConclusionOur results suggest that TLR4 overexpression in mRNA levels is observed in stroke patients, which might account for the probable inflammatory injury before or after stroke. A reduction of IL-8 expression could result from the downregulatory effects of aspirin.     

Analysis of IgG subclass antibodies and expression of T-Cell receptor signaling molecules in anti-CD4 monoclonal antibody treated mice with autoimmune cardiomyopathy

T-cell immune abnormality in patients of dilated cardiomyopathy has been intensively studied over the past 10 years. In this study, we aim to focus on the molecular mechanism of T-cells in autoimmune cardiomyopathy mouse model by detecting the expression of three T-cell signaling molecules. Balb/C mice (n = 12) were immunized with the peptides derived from human ADP/ATP carrier on the 1st, 14th, 28th, 49th and 79th days, and half of them were also injected with anti-L3T4 McAb on the ? 1st, 0 and 1st days. The sham-immunized mice were taken as the controls (n = 6). The main result shows that the antibody response of IgG subclasses such as IgG1, IgG2b and IgG3 were definitely blocked except IgG2a in CD4⁺ cell-depleted Balb/C mice. In addition, the average mRNA expression of p56lck, p59fyn and zap-70 were all found to be dramatically higher in the mice immunized with only ADP/ATP carrier peptides than in the control-group. At meantime, reduced levels of the protein kinases p56lck, p59fyn and zap-70 were clearly observed in anti-CD4 McAb immunized group compared with DCM group. We propose that the proliferation of T-cells was significantly inhibited in anti-CD4 treated mice and CD4⁺ T-cells may play a critical role in ADP/ATP carrier caused mouse DCM.
