Objective To explore the relationship of neuron injury and its severity with the cause and the duration of convulsion Methods Patients were divided into 5 groups or 3 groups according to the causes of convulsion or duration of convulsion in children The levels of neuron specific enolase(NSE) and nitrogen monoxide and nitricoxide synthase(NO/NOS) in serum and cerebrospinal fluid(CSF) were tested by ELISA and spectrophotography at different time points after convulsion in children Results The levels of NSE and NO/NOS in serum and CSF of all objective groups except the febrile convulsion group were apparently higher than those in control group( t =15 4～47 7, P

Objective To detect the variation of neuron specific enolase (NSE) and D dimer in blood from neonates with hypoxic ischemic encephalopathy (HIE), and to explore the correlation of NSE and D dimer with brain damage. Methods NSE and D dimer levels in blood from neonates with HIE were measured by ELISA and turbidimetry before and after therapy. Results Blood NSE and D dimer levels in all objective cases were significantly higher than those in the control cases at 1 d after HIE and 5 d after therapy ( t =2.18-15.17, P

Objective:To investigate the pharmacokinetics of mycophenolic acid( MPA)and its metabolites in different stages af-ter the administration of enteric-coated mycophenolate sodium( EC-MPS)tablets in Chinese liver transplant recipients. Methods:The blood samples of 24 patients were collected in 0-12h of the 1st and 3rd week after the administration of EC-MPS. The concentrations of MPA,AcMPAG and MPAG in plasma were measured by LC-MS/MS developed in our lab. The pharmacokinetic parameters of MPA and its metabolites were estimated by non-compartmental method. Results:After 1-and 3-week therapy with EC-MPS,Cmax ,AUC0-12 and t1/2 was(18. 1 ± 8. 75)and(20. 7 ± 16. 0)μg ml-1 ,(42. 7 ± 17. 5)and(47. 1 ± 23. 9)μg·h·ml-1 ,(3. 33 ± 2. 81)and (3.30 ±1.89)h for MPA;(2.50 ±1.86)and(1.78 ±1.72)μg·ml-1,(14.5 ±11.7)and(6.97 ±6.57)μg·h·ml-1, (4. 48 ± 2. 53)and(3. 76 ± 1. 8)h for AcMPAG;(171. 6 ± 135. 4)and(152. 2 ± 115. 9)μg·ml-1 ,(1299 ± 1 204)and(1 051 ± 561)μg·h·ml-1 ,(8. 73 ± 4. 25)and(7. 75 ± 2. 87)h for MPAG,respectively. There was no significant difference in the PK parameters of MPA after the 1-and 3-week therapy. The Cmax ,Tmax and t1/2 of MPA in the patients received EC-MPS were significantly higher than those in the patients received MMF(P<0. 05). Cmax and AUC0-12 of MPAG in the patients received EC-MPS were signifi-cantly higher than those in the patients received MMF after the 3-week therapy(P<0. 05). Conclusion:There is no significant accu-mulation of MPA after the therapy with EC-MPS at different stages. The absorption of MPA is delayed after the therapy with EC-MPS compared with that with MMF. There is no difference in MPA exposure between EC-MPS and MMF in Chinese liver transplant patients.

Biotrickling filter often offers a cost effective and environmentally friendly alternative to conventional air pollutant control technologies,but major problems with clogging of the filters due to a high biomass accumulation will provent it from the industried uses.In this paper,the effect of the high biomass accumulation in an air pollution treatment with a biotrickling filter is discussed.Two parameters with specific surface area with biofilm growth(?_ f ) and the bed porosity with biofilm(?_ f )are used to analyse its principle of accumulation.Finally,some control measures including chemical methods,physical machine-made methods and other control methods are overviewed.

Objective To assess the clinical short-term to mid-term efficacy of transcatheter closure of coronary artery fistula by using patent ductus arteriosus occluder in pediatric patients. Methods During the period from Jan. 2008 to May 2013 at authors’ hospital, transcatheter closure of coronary artery fistula using patent ductus arteriosus occluder was performed in 8 pediatric patients. The clinical data, including follow-up information, were retrospectively analyzed. Results A total of 8 pediatric patients with a mean age of (4.1 ± 3.8) years were enrolled in this study. The fistula originated from the right coronary artery in five cases and from the left coronary artery in three cases. The blood flow shunted to the right atrium (n=4) or to the right ventricle (n = 4). Obstruction of the fistula was successfully accomplished in all patients. All patients were followed up for (2.2 ± 1.2) years. No procedure-related complications or cardiac ischemia occurred. Conclusion For the treatment of coronary artery fistula in pediatric patients, the use of domestic patent ductus arteriosus occluder is safe and effective with satisfactory short-term to mid-term clinical efficacy.
