Association between matrix metalloproteinase-10 gene polymorphisms and instability of carotid plaque / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To assess the association between 2 single nucleotide polymorphisms (SNPs) located in exonic regions of matrix metalloproteinase-10 (MMP-10) gene and instability of carotid plaques in a Han Chinese population.</p><p><b>METHODS</b>Five hundred and eighty-five patients were divided into carotid vulnerable plaque group (n=206) and stable plaque group (n=379) based on results of carotid B-mode ultrasonography. The SNPs were genotyped by real-time polymerase chain reaction using an ABI 7300 TaqMan platform.</p><p><b>RESULTS</b>The distribution of rs17435959 between the two groups was significantly different at both genotypic (GC+CC vs. GG, P=0.006, OR=2.012) and allelic levels (C vs. G, P=0.001,OR=2.160). Above differences have remained significant with binary logistic regression analysis (P=0.007, OR=2.022; P=0.002, OR=2.104). The minor allele frequency of rs17293607 was 0.56%.</p><p><b>CONCLUSION</b>Above findings suggested that rs17435959 of the MMP-10 gene is associated with carotid vulnerable plaque in ethnic Chinese Hans. The C allele may be a susceptible predictor for carotid vulnerable plaque.</p>

Association between matrix metalloproteinase-8 -799C/T polymorphism and instability of carotid plaque / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the association between a -799C/T polymorphism in the promotor region of matrix metalloproteinase-8 (MMP-8) gene and instability of carotid plaque in Chinese Han population.</p><p><b>METHODS</b>A total of 451 acute infarction patients from the Department of Neurology of Taizhou Hospital were divided into carotid vulnerable plaque group and carotid stable plaque group according to the results of carotid B-mode ultrasonography. Serum MMP -8 level was measured by the means of enzyme-linked immunosorbent assay (ELISA). At the same time, the MMP-8 -799C/T polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.</p><p><b>RESULTS</b>Serum level of MMP-8 in the carotid vulnerable plaque group was higher than that in the carotid stable plaque group (t= 2.894, P= 0.004). The genotype distribution of -799C/T polymorphism between the two groups was significantly different (Chi-square = 13.65, P= 0.000). Serum level of MMP-8 in patients with TT genotype was higher than that in patients with CC genotype (t= 3.141, P= 0.001).</p><p><b>CONCLUSION</b>The present study suggested that serum level of MMP-8 and the -799C/T polymorphism of MMP-8 gene are associated with carotid vulnerable plaque in Chinese Han population, and the T allele may be a predictor for the susceptibility of carotid vulnerable plaque.</p>

Spatial distribution and risk factors of tuberculosis in Songjiang district, Shanghai during 2006 and 2009 / 中华预防医学杂志

<p><b>OBJECTIVE</b>To identify spatial distribution and risk factors among tuberculosis (TB) cases in Songjiang district, Shanghai, 2006 - 2009.</p><p><b>METHODS</b>All active TB cases and all bacteriologically confirmed TB cases diagnosed during the period from 2006 to 2009 were recruited into the study. Spatial scan statistics were used to identify spatial clusters. Using logistic regression, we compared the demographic and clinical characteristics of TB cases in spatial clusters versus TB cases not in spatial clusters.</p><p><b>RESULTS</b>A total of 1815 active TB cases and 730 bacteriologically confirmed TB cases were recruited during 2006 - 2009. Chedun township and Xinqiao township was detected to be a spatial cluste (RR = 1.38, LLR = 16.78, P < 0.01), which was the location of the municipal industrial zone. No spatial cluster was found during 2006 - 2007, while during 2008 - 2009 Chedun township was detected to be a spatial cluster (RR = 1.70, LLR = 15.06, P < 0.01). Among resident population, the spatial cluster of TB cases was located in the southwestern part of Songjiang district, which included five townships Xinbang, Shihudang, Xiaokunshan, Maogang and Yongfeng (RR = 1.49, LLR = 10.52, P < 0.01); while among migrant population, the spatial cluster of TB cases was located in Chedun township (RR = 1.55, LLR = 15.64, P < 0.01). There were higher proportions of resident TB cases who were farmers (AOR = 4.9, 95%CI: 1.9 - 12.3) or had other occupations (AOR = 2.6, 95%CI: 1.1 - 5.9) in the spatial cluster. There were higher proportions of migrant TB cases who lived here for less than 5 years (< 1 year: AOR = 5.9, 95%CI: 1.8 - 19.5; 1 - 5 years: AOR = 3.2, 95%CI: 1.0 - 9.9) or worked at other occupations (AOR = 2.8, 95%CI: 1.5 - 5.1) and lower proportions of migrant TB cases who came from Eastern region (AOR = 0.3, 95%CI: 0.1 - 0.8) or Middle region (AOR = 0.5, 95%CI: 0.3 - 0.9) in the spatial cluster.</p><p><b>CONCLUSION</b>In Songjiang district there was a spatial cluster in TB cases, which was Chedun township. Local residents with TB who were farmers or had other occupations were more likely to be in the spatial cluster. Migrants with TB who lived here for less than 5 years or came from Western region were more likely to be in the spatial cluster.</p>

Association of the ALOX5AP gene SG13S114 A/T polymorphism with atherosclerosis / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the relationship between the polymorphism of SG13S114 A/T in the 5-lipoxygenase-activating protein (ALOX5AP) gene and the stability of carotid atherosclerosis.</p><p><b>METHODS</b>Polymorphism of SG13S114 A/T in the ALOX5AP gene was analyzed in 152 cases of acute infarction with stable plaque, and 132 cases of acute infarction with vulnerable plaques, by using polymerase chain reaction and restriction fragment length polymorphism.

Cerebral magnetic resonance imaging characteristics of eclampsia:an analysis of 15 cases / 中华神经科杂志

Objective To investigate cerebral MRI characteristics of patients with eclampsia. Methods A retrospective study was conducted on 15 cases of eclampsia and items reviewed cover all data concerning clinical features,cerebral MRI findings and results of follow-up survey.Results All of these patients had clinical symptoms of.blurred vision,headache,seizure,hypertension,proteinuria and edema of lower extremity.As for the characteristics of imaging,13 cases had only abnormal symmetric signals in parieto-occipital lobes,frontal lobe and basal ganglia were involved in 2 cases,and temporal lobe was involved in 1 case.The signals of lesions in DWI were isointense or hypointense,however they were hyperintense in ADC map.Two cases had hyperintense signals in DWI.All the patients recovered well,and all brain lesions disappeared during follow up.Conclusion The most important imaging of eclampsia is vasogenic edema with a good prognosis.
