Objective To study the quality of life and influencing factors in children with epilepsy.Methods The psychology of 96 children with epilepsy and 50 normal children were evaluated with the American quality of life and the affecting factors were analyzed.Results The quality of life of the epilepsy children was remarkably lower than that of normal children.The main presentation was seizure worry,side effects of drugs and difficulty of social intercourse.The age of initial presentation.the course of ease and so on affected quality of life in children with epilepsy(P＜0.05 or P＜0.01).The factors such as depression,family.environment,memory function,drug influence and seizure worry played important roles in decreasing order of importance.Conclusion QOL of children with epilepsy was remarkablely lower than normal children.General comprehensive care should be applied to children with epilepsy.Adequate drug treatment to control the seizure attack was very important.

Objective:To investigate the effects of maternal malnutrition on the expression of the insulin signal transduction proteins in the liver of perinatal rats.Methods:(1)The dams were semi-starvation from the first day during pregnancy to build the animal model of intrauterine growth retardation(IUGR).On days 15,17,19,21(E15,E17,E19,E21)of gestation,the fetuses were delivered by cesarean section.The fetal rats,placenta,fetal liver and the fetal brain were weighed respectively.And the placenta weight to the body weight ratio(PWR),the liver weight to the body weight ratio(LWR),the brain weight to the body weight ratio(BWR)were calculated;The expressions of the hepatic insulin receptor(IR),insulin receptor substrate-1(IRS-1),insulin receptor subtrate-2(IRS-2),phosphatidyl inositol 3-kinse(PI3K)mRNA in the rats during perinatal period were detected by RT-PCR.Results:(1)The PWR of the IUGR fetus on E15 was lower than that in the control(P0.05).Conclusion:(1)In order to protect the development of brain,the fetus that suffered maternal malnutrition throughout the pregnancy had liver weight and body weight reduced much more than brain weight,which was known as "brain spare effects".(2)The expressions of hepatic IR mRNA and PI3K mRNA of the fetus were in normal ranges;But the expressions of the hepatic IRS-1 mRNA and IRS-2 mRNA of the IUGR fetus were decreased during the perinatal period.These may be related to the growth retardation and insulin resistance of the adult IUGR rats.

Objective:To investigate the expressions of the insulin receptor(IR),insulin receptor substrate-1(IRS-1),insulin receptor substrate-2(IRS-2),phosphatidyl inositol 3-kinase(PI3K) and insulin-like growth factor-1(IGF-1) of the livers of the male adult rats born with intrauterine growth retardation(IUGR),and to find out the relationship between IUGR and insulin resistance in their adult life.Methods:The foods were available ad libitum throughout the pregnancy to the control group and the rats in the experimental group were fed 50% of the control group to build the IUGR animal model.Liver samples were collected when the male offspring grew up to 12 weeks old.The mRNA expressions of hepatic IR,IRS-1,IRS-2,PI3K,and IGF-1 were detected by RT-PCR.The protein expressions of hepatic IR,IRS-1,and IRS-2 were analyzed by immunohistochemistry.Results:The mRNA expressions of hepatic IR in the adult male rats with IUGR were significantly lower than control group[(0.41?0.06) vs(0.62?0.11),P0.05] in both groups.The mRNA and protein expressions of the hepatic IRS-1[mRNA:(0.77?0.20) vs(1.32?0.42),P0.05].The expressions of hepatic IGF-1 mRNA of the rats with IUGR were significantly lower than those in control group [(0.55?0.12) vs(1.22?0.34),P

Eleven type 1 diabetic patients who received fixed regime of insulin Glargine were included in the study.The levels of fasting serum insulin were measured for each subject at 6:00 in three consecutive mornings.The variability of mean fasting serum insulin in each subject was 3.3%-41.5% (mean 15.4%).The variability did not correlate with the dose of Glargine statistically.

Objective To clone fliH, fliⅠ, fliY and fliN genes that encoding flagellum-associated proteins of L. interrogans for construction of their prokaryotic expression systems, and to determine the loca- tions of Flirt, FliⅠ, FIiY and FIiN. Methods The fliH, fliⅠ, fliY andfliN genes were amplified by PCR and sequenced after T-A cloning. Prokaryotie expression systems of the target genes were constructed subsequently. Expression of target recombinant proteins were demonstrated by SDS-PAGE and BioRad Gel Image Analyzer, and Ni-NTA affinity chromatography was performed to extract the target expression prod- ucts. Rabbits were subcutaneously immunized with the four recombinant proteins respectively to obtain anti- sera. ELISA was performed to measure the titers of antisera and Western blot assay was used to determine the immunobinding abilities among the antisera and their antigens. Immunoelectron microscopy was selected to locate the position of FliH, FliⅠ, FliY and FIiN. Results Segments of fliH, fliⅠ, fliY andfliN genes with 924, 1365, 1065 and 318 bp in size were successfully obtained by PCR. Similarities of nucleotide and puta- tive amino acid sequences from the four genes were 100% compared with the reported sequences. The con- structed prokaryotic systems efficiently expressed rFliH, rFliⅠ, rFliY and rFliN with the outputs of approxi- mate 20% of the total bacterial proteins. The rabbits immunized by rFliH, rFliⅠ, rFliY or rFliN could pro- duce antibody. The antisera had the titers above 1:100 000, and could recognize the corresponding recombi- nant proteins and membrane proteins of L interrogans to display positive Western hybridization bands. Flirt, FliⅠ, FliY and FliN were found to distribute on the external surface of inner envelope, the internal surface of outer envelope or the interspaces between the two layers of L. interrogans envelope. Conclusion The pro- karyotic expression systems was successfully constructed in this study, which could efficiently express flagel-lum-associated proteins FliH, FliⅠ, FliY and FliN of L. interrogans. The antisera with high titers to recognize their protein antigens were also obtained. Flagellum-associated proteins Flirt, FliⅠ, FIiY and FIiN are the inner envelope proteins and/or outer envelope proteins of L. interrogans.

Objective To evaluate the usefulness of baseline ultrasound(BUS) and contrast-enhanced ultrasound(CEUS) in diagnosis of portal vein(PV) patency and to explore the indication of CEUS. Methods The diagnostic capability of BUS and CEUS were assessed in 64 cases according to definition of PV on BUS,which was divided into high, moderate and low definition. Results Thirty-five patients with portal vein thrombosis(PVT) and 29 patients with normal portal vein were confirmed. The diagnostic accuracies by using BUS and CEUS were 93.1% and 96.6% with high definition of PV,56.3% and 87.5% with moderate definition,and 68.4% and 89. 5% with low definition, respectively. Conclusions In the case of high definition of PV,the validity of diagnosing of PV patency with BUS may be similar to that with CEUS,thus introduction of CEUS would probably not be necessary. Otherwise CEUS is recommended.

Objective To measure the dimensional error of three dimensional printing maxilla models for the clinical application to oral and maxillofacial surgery.Methods The FDM 3D printing was employed to make standard geometric shape models and maxillary models.After the surface finish of both models being observed,the contour data and fineness of geometric models,as well as the distance error of bony markers between maxillary models and jaw bones specimen were measured.Results Within the 3D printing standard geometric model,the fiber arrange horizontally in X-Z,Y-Z surface and crosswise in X-Y surface,and the accuracy errors range from-1.67％ to 1.47％.Moreover,the maximum resolution was 0.25 mm in X and Y axis,and 0.50 mm in Z axis.Within the maxillary model,the distance error of bony markers range from-0.08 ％ to 1.96 ％,and the mean errors were 1.59 ％,0.86％,0.42％ in X,Y and Z axis respectively.The mean error in X axis was significantly larger than that in Y or Z axis (P＜0.05).Conclusion 3D printing maxilla models may possess high accuracy and apply to clinical practice.

This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.
