3视网膜微血管异常与MRI确诊的亚临床脑梗死:动脉粥样硬化风险的社区研究显示文摘Background and Purpose-Retinal microvascular abnormalities reflect cumulative small vessel damage from elevated blood pressure and may reflect subclinical cerebral microvascular changes.We examined their associations with MRI-defined cerebral infarcts.Methods-Population-based,cross-sectional study of 1684 persons 55 to 74 years of age without a history of clinical stroke,sampled from 2 US southeastern communities.Retinal photographs were obtained and graded for presence of retinal microvascular abnormalities,including arteriovenous nicking,focal arteriolar narrowing,retinal hemorrhages,soft exudates and microaneurysms.Photographs were also digitized,and retinal vessel diameters were measured and summarized as the arteriole-to-venule ratio(AVR).Cerebral MRI scans were graded for presence of cerebral infarct,defined as a lesion ≥ 3 mm diameter in a vascular distribution with typical imaging characteristics.Results-There were a total of 183 MRI cerebral infarcts.After adjustment for age,gender,race,6-year mean arterial blood pressure,diabetes,and other stroke risk factors,cerebral infarcts were associated with retinal microvascular abnormalities,with odds ratios 1.90(95% CI,1.25 to 2.88)for arteriovenous nicking,1.89(95% CI,1.22 to 2.92)for focal arteriolar narrowing,2.95(95% CI,1.30 to 6.71)for blot hemorrhages,2.08(95% CI,0.69,6.31)for soft exudates,3.17(95% CI,1.05 to 9.64)-for microaneurysms,and 1.74(95% CI,0.95 to 3.21)for smallest compared with largest AVR.In stratified analyses,these associations were only present in persons with hypertension.Conclusions-Retinal microvascular abnormalities are associated with MRI-defined subclinical cerebral infarcts independent of stroke risk factors.These data suggest that retinal photography may be useful for studying subclinical cerebrovascular disease in population-based studies.Cooper L S.

4Plecanatide-mediated activation of guanylate cyclase-C suppresses inflammation-induced colorectal carcinogenesis in Apc+/Min-FCCC mice显示文摘AIM To evaluate the effect of orally administered plecanatide on colorectal dysplasia in Apc^(+/Min-FCCC) mice with dextran sodium sulfate(DSS)-induced inflammation. METHODS Inflammation driven colorectal carcinogenesis was induced in Apc^(+/Min-FCCC) mice by administering DSS in their drinking water. Mice were fed a diet supplemented with plecanatide(0-20 ppm) and its effect on the multiplicity of histopathologically confirmed polypoid,flat and indeterminate dysplasia was evaluated. Plecanatide-mediated activation of guanylate cyclase-C(GC-C) signaling was assessed in colon tissues by measuring cyclic guanosine monophosphate(cG MP) by ELISA, protein kinase G-II and vasodilator stimulated phosphoprotein by immunoblotting. Ki-67, c-myc and cyclin D1 were used as markers of proliferation. Cellular levels and localization of b-catenin in colon tissues were assessed by immunoblotting and immunohistochemistry, respectively. Uroguanylin(UG) and GC-C transcript levels were measured by quantitative reverse transcription polymerase chain reaction(RT-PCR). A mouse cytokine array panel was used to detect cytokines in the supernatant of colon explant cultures. RESULTS Oral treatment of Apc^(+/Min-FCCC) mice with plecanatide produced a statistically significant reduction in the formation of inflammation-driven polypoid, flat and indeterminate dysplasias. This anti-carcinogenic activity of plecanatide was accompanied by activation of cG MP/GC-C signaling mediated inhibition of Wnt/b-catenin signaling and reduced proliferation. Plecanatide also decreased secretion of pro-inflammatory cytokines(IL-6, IL-1 TNF), chemokines(MIP-1, IP-10) and growth factors(GCSF and GMCSF) from colon explants derived from mice with acute DSS-induced inflammation. The effect of plecanatidemediated inhibition of inflammation/dysplasia on endogenous expression of UG and GC-C transcripts was measured in intestinal tissues. Although GC-C expression was not altered appreciably, a statistically significant increase in the level of UG transcripts was detected in the proximal small intestine and colon, potentially due to a reduction in intestinal inflammation and/or neoplasia. Taken together, these results suggest that reductions in endogenous UG, accompanied by dysregulation in GC-C signaling, may be an early event in inflammation-promoted colorectal neoplasia; an event that can potentially be ameliorated by prophylactic intervention with plecanatide.CONCLUSION This study provides the first evidence that orally administered plecanatide reduces the multiplicity of inflammation-driven colonic dysplasia in mice, demonstrating the utility for developing GC-C agonists as chemopreventive agents.Wen-Chi L Chang Shet Masih Anusha Thadi Viren Patwa Apoorva Joshi Harry S Cooper Vaseem A Palejwala Margie L Clapper Kunwar Shailubhai 2017World Journal of Gastrointestinal Pharmacology and Therapeutics2017,8,1:5
