Objective To investigate the effect of antisense oligonucleofide(PCNA ASON)and vascuiar endothelial growth factor (VEGF) gene traneduction on restenosis after balloon angiopasty.Memods chinese rabbits were randomly divided into control group(I),PCNA ASON(II),VEGF only (Ⅲ),PCNA ASON+VEGF(Ⅳ)groups.Each group included 7 rabbits.Restenosis wasevaluated by pathology immunohistochemistry and Western-blotting for the expression of PCNA,and the depth and area oftunica media and tunicca intima were measured. Results All rabbits experienced restenosis on different severities,especially in control group.Lesions were less severe in PCNA ASON and VEGF groups than in controls.The proliferation of smooth muscle and intima significantly ameliorated in PCNA ASON and VEGF combination group that in PCNA ASON or VEGF groups(P<0.01).But the difference between the PCNA ASON and VEGF group was not significant(P>0.7). Conclusion PCNA ASON and VEGF gene transductionn are effective in preventing restenosis after balloon angioplasty caused vessel injury in rabbits.

Objective Type A lamins are encoded by LMNA and a major component of the nuclear lamina, which have been suggested to play important roles in chromatin organization, transcription, DNA replication, and cell apoptosis. The aim of this study was to analyze the bioinformation of zebrafish lamins. Methods A phylogeny analysis was figured out with protein sequences of different species by Clustal X and MEGA 4?0 software. Then we compared the lamin protein sequences of different species with that of zebrafish by BLAST tool from NCBI. A figure of synteny analysis results was done with lamin sequence information of humans, murine and zebrafish cited from UCSC, Vega and Ensemble. Results The a?nalysis results showed that lmna, lmnb1, and lmnb2 genes of zebrafish are highly conservative and they may be homology of human LMNA, LMNB1 and LMNB2 genes. Conclusions Zebrafish lamins and human lamins have homologous sequence similarity, indicating that these two genes are orthologous genes.

Pituitary adenoma is a common neuroendocrine tumor, and its complex pathogenesis makes its treatment a clinical problem. Recently, studies have shown that long non-coding RNA (LncRNA), as a class of endogenous RNA with a length of more than 200 nucleotides and basically no protein-coding function, plays an important regulatory role in various forms in multiple tumors including pituitary adenoma, and is closely related to the proliferation, invasion and metastasis of pituitary adenoma. Based on the latest research status at home and abroad, this paper summarizes the research progress of LncRNA in pituitary adenoma, hoping to provide new ideas for the diagnosis, treatment and prognosis of pituitary adenoma.

Chronic subdural hematoma (cSDH) occurs in acute subdural hemorrhage after head trauma or converts from effusion. Traditional treatment is based on conservative treatment and surgical drainage. The effective rate of conservative treatment is only 3%-18%; even with drilling drainage treatment, the recurrence rate is as high as 33%. Recently, the middle meningeal artery embolization technique based on pathological analysis can greatly reduce the recurrence rate, and the operation is simple and curative effect is exact. This article reviews the pathogenesis of cSDH and progress of interventional therapy.
