ABSTRACT

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0%(29/42) vs. 39.9%(89/223) and 57.1%(24/42) vs. 25.1%(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95% CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

ABSTRACT

Objective To investigate the relationship between different topographic locations and neurological deteriorations (ND) in patients with acute new isolated pontine infarction.Methods One hundred sixty-eight patients with acute new isolated pontine infarction during arch 2012 to March 2016 were identified by diffusion weighted imaging (DWI) for retrospective review.Patients were divided into two groups according to their clinical symptoms:patients with ND and patients without ND.According to neuroimaging of DWI,the topographic location of pontine infarction was divided into three types:The upper,middle,and lower ones,and the correlations of ND with risk factors,laboratory examination results,clinical manifestations and different topographic locations were explored by statistical tests.Results Of 168 patients,26.8% (45/168) were diagnosed with ND,and 73.2% (123/168) were diagnosed without ND.Univariate analysis showed that there were differences in female ratio [62.2% (28/45) vs 41.5% (51/ 123)],smoking ratio [13.3% (6/45) vs 26.0% (32/123)],mean length of hospital stay [(22.83 ± 7.12)d vs (19.31 ± 7.65)d],ratio of worse short-term clinical outcomes [77.8% (35/45) vs 33.3% (41/123)],and ratio of lower pontine infarction [55.6% (25/45) vs 26.0% (32/123)] between two groups (P < 0.05).Logistic regression analysis showed that lower pontine infarction was the independent risk factor of ND (OR =1.953,95% CI:1.092-3.535,P =0.029).Conclusions Topographic location of lower pons lesions may be reliable predictor of ND in acute new isolated pontine infarction.

ABSTRACT

Epithelial tissues covering the external and internal surface of a body are constantly under physical, chemical or biological assaults. To protect the epithelial tissues and maintain their homeostasis, multiple layers of immune defense mechanisms are required. Besides the epithelial tissue-resident immune cells that provide the first line of defense, circulating immune cells are also recruited into the local tissues in response to challenges. Chemokines and chemokine receptors regulate tissue-specific migration, maintenance and functions of immune cells. Among them, chemokine receptor CCR10 and its ligands chemokines CCL27 and CCL28 are uniquely involved in the epithelial immunity. CCL27 is expressed predominantly in the skin by keratinocytes while CCL28 is expressed by epithelial cells of various mucosal tissues. CCR10 is expressed by various subsets of innate-like T cells that are programmed to localize to the skin during their developmental processes in the thymus. Circulating T cells might be imprinted by skin-associated antigen- presenting cells to express CCR10 for their recruitment to the skin during the local immune response. On the other hand, IgA antibody-producing B cells generated in mucosa-associated lymphoid tissues express CCR10 for their migration and maintenance at mucosal sites. Increasing evidence also found that CCR10/ligands are involved in regulation of other immune cells in epithelial immunity and are frequently exploited by epithelium-localizing or -originated cancer cells for their survival, proliferation and evasion from immune surveillance. Herein, we review current knowledge on roles of CCR10/ligands in regulation of epithelial immunity and diseases and speculate on related important questions worth further investigation.

ABSTRACT

Objective To identify and analyze the effective compositions of Schistosoma japonicum 31-32 kDa proteins by using the techniques of proteomics.Methods The total proteins were prepared from 32-day adult worms of Schistosoma japonicum.After two-dimensional(2-D)gel electrophoresis,the distinct protein spots from 2-D gels were isolated and analyzed by MALDI-TOF-MS.Results A total of 13 protein spots,within the range of 31-32 kDa,were detected in the 2-D gels.Three of them had high homology with Actine-2 of S.mansoni,glycerol-3-phosphate dehydrogenase of S.japonicum and cathepsin B endopeptidase of S.mansoni.Conclusions The 31-32 kDa antigens contain 3 important antigens:actine-2,glycerol-3-phosphate dehydrogenase and cathepsin B endopeptidase,which have been demonstrated to have certain protective effect against S.japonicum.Our findings can facilitate the development of multi-epitope vaccine against S.japonicum.
