Objectives To study health-related quality of life(HRQOL) of children with subclinical epileptiform electroencephalographic discharges.Methods Subjects were 30 children with subclinical epileptiform electroencephalographic discharges,50 children with clinical seizures,28 children without clinical seizures and 30 controls.Guardians completed a valid epilepsy-specific HRQOL questionnaire for children,the quality of life in children epilepsy questionnaire(QOLCE).Results Children with subclinical epileptiform electroencephalographic discharges have 8 subscales scores lower than control group,2 subscales scores higher than group with clinical seizures.Conclusions Quality of life of children with subclinical epileptiform electroencephalographic discharges is better than that of children with clinical seizures.However cognitive,behavior,daily life and social activity are impaired by subclinical epileptiform electroencephalographic discharges and lowered the HRQOL of children.

Objective To explore the changes of Clara cell secretory protein(CCSP) in asthmatic children and the effects of inhaling glucocorticoid (ICS) on CCSP.Methods Sixty children with asthma were selected as asthma group(in which 39 cases were male and 21 cases were female,aged 3-12 years old) and 30 healthy children were selected as healthy control group(in which 20 cases were male and 10 cases were female,aged 3-12 years old).Venous blood samples were collected in asthma group and healthy control group in morning before breakfast,and then sera were obtained by centrifuge in speed of 1 500 r?min-1 in 10 min.The dynamic levels of CCSP were measured in sera by enzyme-linked immunosorbent assay.Results 1.In asthmatic children,the CCSP levels in acute episode,3 months after ICS,6 months after ICS, and 12 months after ICS[(5.140?2.331)?g?L-1,(8.730?3.392)?g?L-1,(10.510?2.813)?g?L-1]were all lower than that in healthy control group[(13.230?4.010)?g?L-1](Pa0.05).2.Compared with acute episode,the patients who ICS for 3 months,6 months and 12 months had significantly higher levels of CCSP (Pa0.05).Conclusions CCSP may play a protective role in the airway inflammation of asthma.Glucocorticoid may increase CCSP level in asthmatic children.Glucocorticoid and CCSP may cooperate in anti-inflammation in airway of asthmatic children.

In the cultural construction of independent institute,there exist the contradiction between tradition and innovation,cultural conflicts between private enterprises and the university.Therefore,adhering to the people-centered concept,coordinating tradition and innovation,merging the advantages of university culture and private enterprises culture into a whole,cultivating the unique spiritual culture,harmonious system culture and unified material culture of independent institute,forming the distinctive “Institute Culture” with its own cultural tradition will provide reference for the theory and practice to enrich and improve the connotative development of independent institute.

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.

ObjectiveTo find out the electroencephalogram(EEG)change of the children with language retardation.MethodsThe EEG change and prognosis of 78 cases of language retardation children were analysed and compared with normal ones.ResultsThe EEG abnormal rate of language retardation was 69.3%,while that of the normal children was 10%(P<0.001).Conclusions The EEG is helpful to understand the developmental status of brain functions.

Objective To explore the establishment method of virtual three-dimensional model of the virtual artery and interven-tional devices,and its application value.Methods The virtual models including virtual artery system,catheter,guide wire,stent and coil were established by using the three-dimensional moulding software of 3D Studio MAX R3.The study about interventional preoperative simulation and assistant instruction were run in personal computer.Results ①All the virtual instruments and real in-struments were highly similar shape,the arterial system in the visual display was similar to realistic system.②All arteries branches had own name,could be arbitrarily adjusted curvature,diameter and established the lesion morphology.③The reference value of preoperative simulation results to guide the actual surgery included following aspects:to guide the reasonable shaping of micro-cathe-ter and micro-guide wire tip,to plan the coil and stent deployment location,number and size.④In training and teaching,the preop-erative simulation could assist doctors in learning and remembering the artery branch and establishing the concept of three-dimen-sional space,and enhanceing the intention understanding of surgery.Conclusion The establishment method of virtual model of the virtual artery and interventional devices is reliable.The preoperative simulation results can be used to guide practical operation with relatively high accuracy,and it has an important supporting role for the teaching and training of medical students.

Objective To explore the role and clinical significance of interleukin-6(IL-6) in children with bronchial asthma.Methods Sera were collected from 29 cases with asthmatic attacks,32 asthmatic children who in stable conditions,and 20 health children.Serum IL-6 concentrations were measured by radioimmunoassay(RIA).Results 1.Asthmatic children appeared significantly higher levels of serum IL-6 during asthmatic attacks as compared to those in stable conditions and healthy ones respectively(P3 years old had significantly higher serum IL6 concentrations than ≤3 years old children in remission.Conclusion IL-6 may participate pathogenesis of asthma,and it may play different biological roles during asthmatic attacksas or stable conditions.

Objective To identify a unique protein as a novel genetic marker for rapid molecular typing of Mycobacteriutn tuberculosis Beijing genotype strains by comparing the proteome of Beijing genotype strains with non-Beijing strains.Methods Fifty-six clinical isolates of Mycobacterium tuber- culosis were analyzed by spoligotyping to determine genotypes.The two-dimensional electrophoresis (2 DE)was used to compare the global protein patterns between Beijing genotype strains and non Bei jing strains.Differential expressed proteins were measured by matrix assisted laser desorption ioniza tion lime of flight mass spectrometry(MALDI-TOF-MS).The data obtained from peptide mass fingerprinting were compared in protein database.The genes encoding differential expressed proteins and their upstream were sequenced.Results Forty nine of the 56 isolates were Beijing genotype strains and 7 isolates were non-Beijing strains.A unique protein Rv0927c was identified,which is absent in Beijing genotype strains compared with 7 non Beijing strains and H37Rv.There were two characteristic mutations in Beijing genotype strains,a deletion of AGC at nucleotide position 421 of Rv0927c and a 127 G→A muta- tion in the upstream of Rv0927c.but not in non Beijing strains and H37Rv.Conclusion Characteris tic mutations of Rv0927c in Beijing genotype strains can be used as a novel genetic marker for rapid molecular typing of Mycobacteriuln tuberculosis Beijing genotype strains and non Beijing strains.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

OBJECTIVETo investigate the liver injury in model rats with endotoxemia and to observe the protective effect of Compound 912 Liquid on it.

METHODSRats were randomly divided into three groups, the endotoxemia model group (EMG, injected by lipoplysaccharides (LPS) peritoneally), the intervention group (IG, treated with Compound 912 Liquid via gastrogavage 1 h before model establishing) and the normal control group (NCG). Blood samples of rats were taken at the time points of the 2nd, 4th, 8th, 12th, 48th, 72nd hour and the 7th day after modeling for measuring liver function, levels of plasmatic endotoxin, tumor necrosis factor alpha (TNF-alpha), interleukin-10 (IL-10). The pathological change of liver was observed using light microscope and electro-transmission microscope.

RESULTSThe peak concentration of endotoxin detected at 2 hour after modeling in the IG was significantly lower than that in the EMG (0.358 +/- 0.056 vs 0.685 +/- 0.030), but insignificant difference (P > 0.05) was shown between them in TNF-alpha level. The level of IL-10 continuously rose in IG after treatment, it was still higher than normal level until day 7 (49.096 +/- 4.076 vs 43.454 +/- 5.928, P < 0.05).

CONCLUSIONLPS can induce the increase of serum inflammatory cytokines and anti-inflammatory cytokines in rats to injure liver. Therefore, the inflammatory reaction indicated by LPS may be one of the mechanisms for liver injury. Preventive medication with Compound 912 Liquid showed a significant liver protective effect.
