Unlike the common development of renal angiomyolipoma, hepatic angiomyolipoma rarely occur in patients with TSC. We report here a patient with hepatic angiomyolipomas and concurrent hepatocellular carcinoma in TSC. This represents the first reported case in English literature. In this patient, multiple hepatic angiomyolipomas were diagnosed with recognition of their fat components and typical clinical settings. Hepatocellular carcinoma in the left liver lobe was definitely diagnosed by US guided biopsy. In such clinical settings, fat containing lesions in liver can be reasonably treated as angiomyolipomas, but non fat containing lesions must be differentiated from hepatocellular carcinoma, imaging guided biopsy can be adopted to confirm the diagnosis.展开更多

Routine group were treated with routine western medicine plus Danshen Dropping Pill, auricular point pressing group were treated with auricular point pressing on the basis of the therapy of routine group, and both groups had been continuously treated for 1 month. The differences in platelet function, inflammatory response and protease expression were compared between the two groups before and after treatment.Results:Before treatment, there was no statistically significant difference in the platelet activation index levels, serum inflammatory factor contents or protease expression between the two groups. After 1 month of treatment, peripheral blood platelet activation index CD42b level of auricular point pressing group was higher than that of routine group whereas CD63 and PAC-1 levels were lower than those of routine group;serum inflammatory factors IL-6, IL-10, IL-18 and hs-CRP contents were lower than those of routine group;serum proteases MMP-1, MMP-2 and MMP-9 contents were lower than those of routine group.Conclusion:Compound Danshen Dropping Pill combined with auricular point pressing can further optimize the platelet function and improve the systemic inflammatory state and protease expression in patients with stable angina pectoris.展开更多

Raf.) exhibited enhanced cold tolerance relative to their diploid progenitors.Transcriptome analysis revealed that whole-genome duplication was associated with higher expression levels of a range of well-characterized cold stress-responsive genes.Global DNA methylation profiling demonstrated that the tetraploids underwent more extensive DNA demethylation in comparison with the diploids under cold stress.CHH methylation in the promoters was associated with up-regulation of related genes,whereas CG,CHG,and CHH methylation in the 3’-regions was relevant to gene down-regulation.Of note,genes involved in unsaturated fatty acids(UFAs) and jasmonate(JA)biosynthesis in the tetraploids displayed different CHH methylation in the gene flanking regions and were prominently up-regulated,consistent with greater accumulation of UFAs and JA when exposed to the cold stress.Collectively,our findings explored the difference in cold stress response between diploids and tetraploids at both transcriptional and epigenetic levels,and gained new insight into the molecular mechanisms underlying enhanced cold tolerance of the tetraploid.These results contribute to uncovering a novel regulatory role of DNA methylation in better cold tolerance of polyploids.展开更多

文摘Polyploids have elevated stress tolerance,but the underlying mechanisms remain largely elusive.In this study,we showed that naturally occurring tetraploid plants of trifoliate orange(Poncirus trifoliata(L.) Raf.) exhibited enhanced cold tolerance relative to their diploid progenitors.Transcriptome analysis revealed that whole-genome duplication was associated with higher expression levels of a range of well-characterized cold stress-responsive genes.Global DNA methylation profiling demonstrated that the tetraploids underwent more extensive DNA demethylation in comparison with the diploids under cold stress.CHH methylation in the promoters was associated with up-regulation of related genes,whereas CG,CHG,and CHH methylation in the 3’-regions was relevant to gene down-regulation.Of note,genes involved in unsaturated fatty acids(UFAs) and jasmonate(JA)biosynthesis in the tetraploids displayed different CHH methylation in the gene flanking regions and were prominently up-regulated,consistent with greater accumulation of UFAs and JA when exposed to the cold stress.Collectively,our findings explored the difference in cold stress response between diploids and tetraploids at both transcriptional and epigenetic levels,and gained new insight into the molecular mechanisms underlying enhanced cold tolerance of the tetraploid.These results contribute to uncovering a novel regulatory role of DNA methylation in better cold tolerance of polyploids.
