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.

In general the valuation criterions of teaching quality in class are exactness,lifelikeness and profundity.The author's own understanding and some suggestions about the criterions will be put forward in this article.

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.

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.

OBJECTIVE: Polyurethane (PU) and silicon rubber have good biocompatibility, excellent mechanical properties, easy processing and controlled properties, etc. Therefore, their researches exhibit an important significance in the designs of the medical appliance and body apparatus.DATA SOURCES: The computer respectively indexed the database articles of abroad El, SCI, CA, Science Direct (Elsevier) and Chinese periodical full text from January 1995 to May 2006, the indexed words were "Silicon rubber, polyurethane, medical materials", the article language category was limited respectively in English and Chinese.STUDY SELECTION: The relevant articles (full text) that meet the study were selected by the first trial. Inclusion criteria: ① Related to silicon rubber and polyurethane. ② The medical rubber apparatus and body organ design. Exclusion criteria: The repetitive studies.DATA EXTRACTION: Collect totally 122 relevant articles that use the medicinal rubber materials, and expel the repetitive or similar research,therefore 16 articles meeting the request.DATA SYNTHESIS: ① Medicinal gum, hose and other products: The medical stopper used for sealing is requested to have the flexibility,resistant to cold, water, oil and disinfectant, and pinprick can still keep the original closeness and gastightness, etc. ② The abroad body organs: The material of repairing fracture, skull, meninges, bridge, auricle, mandible,windpipe, tear bolt, lung membrane, heart valve, stomach, intestine,peritoneum, penis, knuckle, muscle, knee membrane, skin and breast. ③ The research and expectation of the medicinal silicon rubber and polyurethane offer more medicinal apparatus and body organ.CONCLUSION: The study of the medicinal silicon rubber and polyurethane make people design and produce more cheap artificial organ and medicinal apparatus. More materials were applied to the clinic, so that satisfy the demand of many patients.

Objective:To discuss the experience accumulation and thinking tralning of clinical pharmacist in the pharmaceutical consultation with SOAP model. Methods:Clinical pharmacist performed the condition evaluation for one patient with Acinetobacter bau-rnannii infection after esophagus cancer surgery and was invited to the consultation for three times. Clinical pharmacist also provided the references for the drug treatment and monitored the whole process. Clinical pharmacist actively followed and pald return visits for the prognosis of the patient for one month. Results: After identifying the pathogen, the experiential therapy was given and the condi-tions of the patient were improved. According to the changes of the conditions, the treatment was adjusted in time with the most suitable drugs for the conditions and infection degree. Finally, the infection was controlled effectively, and the patient was discharged after the 35-day postoperative treatment. Conclusion:During the consultation, clinical pharmacist should correctly judge the conditions of pa-tients, summarize and evaluate the earlier therapy results, and then choose suitable drugs according to the property of PK/PD. Clinical pharmacist also should track the therapy results to assess the conditions of patients and individualize the treatment.
