Objective To explore the influence of lamotrigine(LTG)and valproate(VAP)on cognitive function in children with epilepsy.Methods Seventy-six epileptic children firstly diagnosed were chosen,36 cases received LTG monotherapy and 40 cases undwent the treatment of VPA.The intelligence quotient(IQ)value was measured before and after 6 months treatment respectively,and 20 healthy children were selected as healthy control.Results 1.The epileptic children had poor verbal intelligence quotient(VIQ),performance intelligence quotient(PIQ)and full intelligence quotient(FIQ)compared to the control subjects(Pa0.05).But among the subtestings,the know-ledge,wood-graph,coded score of the VPA groups had significant difference(Pa

OBJECTIVEThe purpose of this study is to construct a pyruvate oxidase gene deficiency variant strain of Streptococcus oralis (S. oralis).

METHODSThe sopox gene, which was got using polymerase chain reaction (PCR), and the 130-basepair segment of which was cut down with endonuclease BamHI, and transferred into S. oralis (ATCC10557) by using electrotransformation. The authors obtained a variant strain of S. oralis, and then the catalase activity of the first culture and 3-4 subcultures was examined.

RESULTSThe authors obtained a pyruvate oxidase gene deficiency variant strain of S. orlis. The catalase activity examination showed that the ability of producing H2 O2 of the variant strain of S. orlis declined, whose catalase activity was between those of the positive control (ATCC10557) and the negative control (Escherichia coli, JM109). But the produced H2 O2 quantity of their subcultures was less than that of the negative control.

CONCLUSIONThe construction of the pyruvate oxidase gene deficiency variant strain of Streptococcus oralis is successful.

AIM: To measure the macular thickness of normal young people by 3D 1000 optical coherence tomography (OCT) and study the repeatability of measuring results and the relationship between the thicknesses of macular and gender. At the same time, to compare our result with the data of other types of OCT, and to understand the consistency of the measuring results of macular thickness of different types of OCT.
METHODS: Totally 222 eyes in 111 young people were detected using 3D scan mode of Topcon 3D OCT 1000 (ver 2.4 ) . Twelve cases ( 24 eyes ) underwent repeatability check. We took transverse comparison between our measured results with other research's results.
RESULTS: There were 111 cases of young people, whose age were from 18-27 years old, all uncorrected and corrected visual acuity were≥1. 0, all intraocular pressure were <21mmHg. The average thickness of all macular region was 273. 32±17.08μm. Retinal volume of macular area was 7. 73 ± 0.37mm3 . Center thickness was 161 -264μm, and the average thickness was 200. 13±18. 81μm. Central macular thickness were 188 - 273μm, and the average thickness was 229. 00 ± 18. 20μm. The central macular thickness in men was significantly greater than that in women, and there was statistical difference. The results of repeated check of 12 cases ( 24 eyes ) in the macular area were no statistical difference except the outer ring of nasal quadrant, and the repeatability of average thickness in central macular thickness was better than in center thickness.
CONCLUSION:The repeatability of macular examination is good. The central macular thickness can be better repeated than the center thickness. The central macular thickness is 229. 00±18. 20μm in young people, according to the 3D 1000 OCT measurements. There are statistical difference of central macular thickness between different genders.

Objective To investigate the early-pathologic changes in children′s antrum infected with different types of Hp and study the Hp isolate′s pathogenic.Methods The serum types of CagA and VacA from Hp were determined by Westen-Blot in 70 patients with Hp positive and 36 patients with Hp negative.The standard of gastritis pathologic classification was accordance with that of international made in Sydney. The pathogenic of Hp affecting was evaluated by the degree of inflammation, severity of active gastritis,lymph follicles and atrophy.Results The detection rate of type Ⅰwith high virulence in Hp isolates was 68.1%,mid-type isolates was 27.7% and type Ⅱ with low virulence isolates was 4.2%.To observe the pathologic distinction in 49 patients with type Ⅰisolate,20 patients with mid-type isolate and 3 patients with type Ⅱ isolate,the type Ⅰ and mid-type isolates had significant difference in inflammation and their activity in either antrum or duodenal ampulla.Three patients with type Ⅱ isolate have not active gastritis.Type Ⅰand mid-type isolates had significant difference in lymph follicles,and the lymph follicles caused by type Ⅰwere significant higher than those caused by mid-type.But there were no significant differences in intestinal metaplasia and atrophy.Conclusions TypeⅠisolate with high virulence is the main detection isolate of children infected by Hp in our district.There is inflammation occurrence in antrum specimens in childhood who infected with Hp.

BACKGROUND:Poly(lactide-co-glycolide) (PLGA) scaffold is widely used in tissue engineering, but its poor cel adhesion ability and strong hydrophobicity limit its further development and application. OBJECTIVE: To study the biocompatibility of electrospun poly (lactide-co-glycolide)/polyethylene glycol (PLGA-PEG) nanofibrous scaffolds with mouse neural stem celsin vitro. METHODS:Neural stem cels were isolated from embryos of CD-1 mice at 15 embryonic days. Electrospinning was used to prepare PLGA and PLGA-PEG nanofibrous scaffolds. Scanning electron microscope was used for scanning observation of scaffolds. The 5th passage neural stem cels were seeded onto PLGA and PLGA-PEG scaffolds respectively, and culturedin vitro. RESULTS AND CONCLUSION: Interconnected porous network structure was observed in both two kinds of scaffolds under the scanning electron microscope. Fiber diameters and porosities of PLGA and PLGA-PEG scaffolds showed no significant differences (P > 0.05). Cel Counting Kit-8 detection showed neural stem cels grew wel on both two kinds of scaffolds and the absorbance value of two groups increased continuously with incubation time (1, 3, 5, 7, 9, 11 days). And there were statisticaly significant differences in the absorbance values between two groups at each time point (P < 0.05). Moreover, the cel adhesion rate was significantly higher in the PLGA-PEG group than in the PLGA group at 3, 6, 9 hours of culture (P < 0.05). Hoechst 33342 staining showed normal morphology and quality of the nuclei, and significantly more cels were observed in the PLGA-PEG group than the PLGA group (P < 0.05). Under the scanning electron microscope, compared with the PLGA scaffold, the PLGA-PEG scaffold was better for growth and matrix secretion of neural stem cels. In conclusion, PLGA-PEG nanofibrous scaffolds prepared by electrospinning are safe, non-toxic and suitable for neural stem cels growth with wel biocompatibility, appropriate aperture and porosity.
