With the advances of medical management and surgical techniques during cardiopulmonary bypass,children with congenital heart disease are increasingly surviving to adulthood.Research into their neurodevelopmental outcomes in the past 20 years had revealed sobering realizations about the adverse impact on the quality of life of these surgical survivors.A multitude of factors contribute to the incidence and severity of neurodevelopmental abnormalities and can be separated into preoperative,intraoperative,and postoperative events,in addition to genetic contributions and socioeconomic factors.This article highlight some of current understanding of these protean factors.Understanding should lead to modification of current techniques and management strategies,all with the ultimate goal of improving patients' quality of life.

Objective: To express and purify the inhibitor of differentiation(Id3) in E.coli.Methods: The DNA fragment in the coding region of the human Id3 gene was amplified by PCR and cloned into the pGEM-T Easy vector for sequencing.The Id3 cDNA fragment was then subcloned into the prokaryotic expression vector(pET-32a)(+) and transformed into E.coli BL 21(DE3).The expression of the histidine-tagged(His-Tag) fusion protein was induced with isopropy-?-D-thiogalactoside(IPTG),confirmed by Western blot and purified by the immobilized Ni2+ absorption chromatographic column.Results: The prokaryotic expression vector of Id3 was successfully constructed.Western blot confirmed the expression of the His-Tag fusion protein in E.coli BL 21(DE3) and that of the Id3 fusion protein with the relative molecular mass size of 33 000 after purified by the affinity chromatographic column. Conclusion: Recombinant Id3 can be expressed in E.coli BL 21(DE3) and the obtained fusion protein can be purified by the Ni-affinity chromatography column.

Integrins such as αvβ3, α5β1 play a key role in angiogenesis regulation, invasion and metastasis, inflammation, wound healing, etc. The up-regulation of integrin αvβ3 after cerebral ischemic stroke can promote angiogenesis, which in turn improves functional recovery. In addition, the integrin αvβ3 inhibitor can block the blood-brain barrier (BBB) leakage induced by vascular endothelial growth factor (VEGF) and also can reduce inflammatory reaction, decrease the deposition of fibrinogen. Other studies showed that integrin αvβ3 is not essential in revascularization. Therefore, the effect of integrin αvβ3 in the whole process of brain function recovery merits further study.

As a member of homeobox gene family,HOXC is expressed in many organs and can regulate gene expression,cell differentiation and morphogenesis.Abnormality of its function is closely related to the prognosis of leukemia,breast cancer,renal cell carcinoma,prostate cancer and so on.

Objective To explore the influencing factors of therapeutic effect and prognosis in patients with angioimmunoblastic T cell lymphoma (AITL). Methods The clinical data of 48 patients with AITL were collected in order to evaluate its therapeutic effect and the influencing factors of prognosis. Results In the 48 patients with AITL, complete remission (CR) was in 15 cases, partial remission (PR) was in 16 cases, and the total effective rate was 64.58%(31/48). The recent total effective rate in patients of international prognostic index (IPI) score ≤2 scores was significantly higher than that in patients of IPI score >2 scores: 84.00% (21/25) vs. 43.48% (10/23), and there was statistical difference (P<0.05). The 1-year, 2-year and 3-year overall survival rates were 75.00%(36/48), 52.08%(25/48) and 35.42%(17/48), and the median survival time was 24.5 months. The patients of Ann Arbor stage Ⅰ-Ⅱ, IPI score ≤ 2 scores, Ki-67<50% and using CHOP combined with asparaginase (ASP) regimen had a higher 3-year overall survival rate compared with the patients of Ann Arbor stage Ann Arbor stage Ⅲ -Ⅳ, IPI score >2 scores, Ki-67 ≥ 50% and using CHOP regimen: 8/13 vs. 25.71%(9/35), 52.00% (13/25) vs. 17.39% (4/23), 55.00% (11/20) vs. 21.43% (6/28) and 48.28% (14/29) vs. 3/19, and there were statistical differences (P<0.05). Conclusions AITL is a kind of disease with poor prognosis. IPI score is the important influencing factor of recent therapeutic effect. The Ann Arbor stage, IPI score, Ki-67 levels and using contained ASP chemotherapy are the important factors of prognosis in patients with AITL.
