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.

ObjectiveTo investigate the extracorporeal clearance rate of imipenem in severe infection patients in the mode of continuous vena-venous hemofiltration (CVVH) during continuous renal replacement therapy (CRRT), in order to approach if the concentration of imipenem in plasma could achieve effective levels of anti-infection, and to explore the effect of time and anticoagulation measure on imipenem clearance during CRRT treatment.Methods A prospective observational study was conducted. All adult severe infection patients complicating acute kidney injury (AKI) in the Department of Critical Care Medicine of the Fourth Hospital of Hebei Medical University from March 2013 to September 2014, who were prescribed imipenem as part of their required medical care, and CRRT for treatment of AKI were enrolled. 0.5 g doses of imipenem was administered intravenously every 6 hours or 8 hours according to random number table, and infused over 0.5 hour. The unfractionated heparin was used for anticoagulation in the patients without contraindications, and no anticoagulation strategy was used in the patients with high risk of bleeding. At 24 hours after first time of administration, postfilter venous blood and ultrafiltrate samples were collected at 0, 0.25, 0.5, 0.75, 1, 2, 5, 6, and 8 hours after imipenem administration. The concentration of imipenem in above samples was determined with liquid chromatography-mass spectrometer/mass spectrometer (LC-MS/MS).Results A total of 25 patients were enrolled. Thirteen patients received imipenem intravenously every 6 hours, and 12 patients, every 8 hours. The anticoagulation was conducted with heparin in 13 cases, and 12 cases without anticoagulation. The intra-day precision, inter-day precision, matrix effect, and recovery rate in low, medium, and high concentration of plasma and ultrafiltrate, and the stability of samples under different conditions showed a good result, the error of accuracy was controlled in the range of±15%. With the application of Prismaflex blood filtration system and AN69-M100 filter, under the mode with CVVH, the total clearance rate of imipenem was (8.874±2.828) L/h when the actual dose of replacement fluid was (31.63±1.48) mL·kg-1·h-1, the total CRRT clearance rate of imipenem in vitro was (2.211±0.539) L/h, which accounting for (30.1±15.7)% of the total drug clearance. In 6 hours interval dosage regimen, the percentages of the time> 4×minimum inhibitory concentration (MIC) at specific 4×MIC of 2, 4, 6, and 8μg/mL of imipenem were more than 40% of the dosing interval. But in the 8 hours interval dosage regimen, when the level was above the 4×MIC of 4μg/mL, maintaining time would drop below 40% of the dosing interval, with significant differences compared with that in 6 hours interval dosage regimen [4×MIC = 2μg/mL: (60.84±20.25)%vs. (94.01±12.46)%,t = 4.977,P = 0.001; 4×MIC = 4μg/mL: (39.85±15.88)% vs. (68.74±9.57)%,t = 5.562, P = 0.000; 4×MIC = 6μg/mL: (27.58±13.70)% vs. (53.97±8.36)%,t = 5.867,P = 0.000; 4×MIC = 8μg/mL:(18.87±12.43)% vs. (43.48±7.83)%,t = 5.976,P = 0.000]. No significant change in sieving coefficient of imipenem was found within a short time (6 hours), which indicated that there was no effect of anticoagulation on clearance of imipenem by AN69-M100 filter, and no statistical significance was found with repeated measure analysis (F = 0.186, P> 0.05).ConclusionsThe clearance rate of imipenem is increased significantly in vitro under the mode of CVVH with the actual dose of replacement fluid was (31.63±1.48) mL·kg-1·h-1 in severe infective patients with severe sepsis complicating AKI, affecting the level of plasma drug concentration, need to adjust the dosage regimen. When the time of the dosing interval was shortened, the concentration of imipenem in patients' plasma could be increased significantly. In a short period of time, the sieving coefficient of imipenem through AN69 filter is not affected by anticoagulation measures and time cleaning efficiency will not decline.

OBJECTIVE:To observe the effects of different routes of administration of tranexamic acid on coagulation function and amount of bleeding in patients with one stage posterior surgery of thoracic tuberculosis. METHODS:40 patients suffered from thoracic tuberculosis in our hospital from Jan. 2011 to Dec. 2013 were randomly divided into intravenous group(5% Glucose injec-tion 100 ml+tranexamic acid 10 mg/kg,through an intravenous drip at 30 min before closing the wound) and topical application group(5% Glucose injection 10 ml and tranexamic acid 10 mg/kg,through soaking the wound before closing the wound)with 20 cases in each group. Other 15 cases suffered from the thoracic tuberculosis in our hospital from Jan. 2009 to Dec. 2010 were includ-ed in control group. 3 groups received one stage posterior surgery of thoracic tuberculosis,interbody fusion and internal fixation. The difference of hemoglobin,coagulation function and the amount of suction drainage were observed before and after surgery, and followed up. Bone graft fusion and therapeutic condition of tuberculosis were observed in the study. RESULTS:There was no statistical significance in postoperative suction drainage between intravenous group and topical application group (P>0.05),but their decrease was more significant than control group,with statistical significance(P<0.05). There was no statistically difference in fiber protease,prothrombin time or activated partial thromboplastin time among 3 groups(P>0.05). The difference value of he-moglobin in control group before and after operation was significantly higher than in intravenous group and topical application group,with statistical significance (P<0.05);there was no statistical significance between intravenous group and topical applica-tion group(P>0.05). 55 patients were all followed up and bone graft of all cases were fused,and all patients were cured and no case recurred. CONCLUSIONS:Tranexamic acid by intravenous application or topical application can reduce hemorrhage and ane-mia after operation of thoracic tuberculosis,and has no effect on blood coagulative system.

Due to the characteristics and environmental factors, electrocardiogram (ECG) signals are usually interfered by noises in the course of signal acquisition, so it is crucial for ECG intelligent analysis to eliminate noises in ECG signals. On the basis of wavelet transform, threshold parameters were improved and a more appropriate threshold expression was proposed. The discrete wavelet coefficients were processed using the improved threshold parameters, the accurate wavelet coefficients without noises were gained through inverse discrete wavelet transform, and then more original signal coefficients could be preserved. MIT-BIH arrythmia database was used to validate the method. Simulation results showed that the improved method could achieve better denoising effect than the traditional ones.
