A lot of children with congenital heart disease have an abnormal development of nervous system. A variety of biochemical and physical examination indices can be used to predict adverse outcome of neurodevelopment caused by congenital heart disease and they contribute to early intervention and improvement of neurodevelopmental disorders. In recent years, new progresses in the laboratory tests, neurological physiccal examination and perioperative management of the neurodevelopmental abnormalities caused by congenital heart disease have been made. The predictive factors of abnormal neurodevelopment caused by congenital heart disease were reviewed in this article.

Objective To determine the effects of maternal rats exposed to chronic unpredictable stress before pregnancy on the behavior and neurobiology of the mother and their offspring.Methods Two-month Virgin female Sprague-Dawley(SD) rats were applied to study.Females were housed with sexually experienced males (ratio 3:1) for propagation after 21-day chronic unpredictable stress.The behaviors of rats and their two-month-offspring were tested.The two-month rats were injected intraperitoneally with BrdU,then the brains were removed and 20 μm frozen sections were used to detect the neurogenesis of hippocampus.Results 1.Open field test:after lactation,CUS + Pre group ((720.52 ± 238.99) cm),CUS group ((995.62 ± 191.77) cm),CON group ((464.95 ±210.11)cm) and CON + Pre group((740.76 ± 281.48)cm) had statistic difference in total distance(P ＜ 0.05).The total distance((1281.10 ±247.89)cm) and border distance((1153.20 ±238.19)cm) in female two-monthprogeny were higher than these in male two-month-progeny ((1074.70 ± 263.35) cm,(957.28 ± 82.94) cm) in CUS + Pre group (P ＜ 0.05).2.Sucrose consumption test:after lactation,the sucrose intake ((13.00 ± 3.46) g)and sucrose consumption percentage((87.00 ±9.01)％) in CUS + Pre group were higher than that in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％,P ＜ 0.05).The sucrose intake ((12.43 ± 3.31) g) and sucrose consumption percentage((86.90 ± 5.80)％) in CON group were higher than that in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％,P ＜ 0.05).The sucrose intake ((14.71 ± 4.39) g) and sucrose consumption percentage ((91.54 ± 1.89) ％) in CON + Pre group were significantly higher than those in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％) (P ＜ 0.01).3.Immunohistochemistry:there was no statistic difference on the new neuron in dentate gyrus of hippocampus in both female and male two-month-progeny of CUS group and CON group((1.18 ±0.37) cells,(1.24 ± 0.41) cells,(1.38 ± 0.47) cells,(1.41 ± 0.35) cells) (P ＞ 0.05).Conclusion The 21d CUS before pregnancy induce the anxiety-like behavior and depressive-like behavior in maternal rats,and lactation can attenuate influence of stress to protect maternal rats.There is no effect on the behavior and cell proliferation of hippocampus in adult progeny by chronic unpredictable stress exposure before pregnancy.However,there is the difference of anxiety-like behavior in both female and male two-month-progeny.

BACKGROUND: Acellular vascular matrix as vascular scaffold has following advantages: acellular vascular matrix possesses complicated three-dimensional structure of natural blood vessels. Growth factor and structural domain on the surface of acellular matrix helps for cell adhesion and infiltration.OBJECTIVE: To prepare acellular vascular matrix material and to evaluate its biocompatibility in vivo and in vitro.METHODS: Trypsin and Triton X-100 were used to gradually dispose pig carotid artery and to prepare acellular vascular matrix. The biocompstibility of the material was evaluated by implantation in muscle, acute toxicity experiment and cytotoxicity test in vitro.RESULTS AND CONCLUSION: The acallular vascular matrix material possessed good chemical stability and did not release harmful factors that produced destruction and dissolution in erythrocytes, without acute hemolytic reaction or toxic effects on cell growth. The acellular vascular matrix material showed lots of inflammatory cell infiltration in eady stage of implantation, and no significant inflammatory cell infiltration in late stage of observation. Fibroblasts were visible in the acellular matrix. In addition, the acellular matrix material did not exhibit toxic effects on surrounding tissues, showing wound stage I healing. Simultaneously,histological sections demonstrated that there were good compatibility of scaffold material and surrounding tissues, without rejection. These indicated that acellular matrix material presented good biocompatibility in animals.

BACKGROUND: Titanium alloy implant has been widely used in the clinic. But there are few reports addressing on corrosion performance of medical titanium alloy dental implant, in particular in different physiological electrolytes. OBJECTIVE: To investigate the corrosion behaviors of medical titanium alloys in physiological saline, simulated saliva, and simulated body fluid. DESIGN, TIME AND SETTING: A randomized grouping, controlled observation was performed at the School of Stomatology, Lanzhou University and State Key Laboratory of Solid Lubdcation, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences between November 2008 and March 2009. MATERIALS: Medical titanium alloys (Ti-6Al-4V) were cut into 10 mm×10 min×1 mm sheets and were randomly divided into 3 groups, with 10 sheets in each group. METHODS: Corrosion performance of titanium alloys in physiological saline, simulated saliva, and simulated body fluid was investigated using electrochemical measurements. Following electrochemical corrosion, surface morphologies and wettability of samples were also observed using scanning electron microscope and CA-A type contact angle tester. MAIN OUTCOME MEASURES: Tafel curve, surface morphology, and contact angle of medical titanium alloys in three physiological electrolytes after 4 days of electrochemical corrosion. RESULTS: The corrosion of titanium alloys was most severe in simulated saliva, followed by simulated body fluid, and mildest in physiological saline. Scanning electron microscope results demonstrated that medical titanium alloy surface exhibited many holes after corrosion by physiological saline, showed rough surface with a slightly changed number of holes after corrosion by simulated body fluid, and presented with an increased number of holes, with aperture greatly increased in some holes after corrosion by simulated saliva. The contact angles of titanium alloys were all reduced after corrosion of three electrolytes. CONCLUSION: The corrosion of titanium alloy was most serious in simulated saliva. Thus, corresponding protection measures should be given in clinical application.
