Objective To explore the influence of subclinical epileptiform discharge(SED) on mathematics cognitive function. Methods Using event-related potential (ERP) detection method by stimulation of mathematical operation,11 patients with benign epilepsy of children with centrotemporal spikes (BECTS group),who treated with Valproate sodium (VPA) and clinical seizures got under control,but had frequent SED,and 11 normal children (NC group) were detected. The results were analysed. Results Compared with NC group,the P3 latencies of all leads in BECTS group were significantly prolongation (all P

Objective To study the MR imaging features of intracranial subependymomas and to improve the knowledge more about it. Methods The imaging features of intracranial subependymomas in 17 cases proved pathologically were retrospectively analyzed, among which 11 cases were male and 6 cases were female, 16 cases had MR images and 1 case only had CT images.Results MR appearances of intracranial subependymomas were as follows :16 cases were all hyperintense relative to the normal grey matter on T2-weighted images and hypointense or isointense on T1-weighted images. 12 cases showed no enhancement or minimal enhancement after Gd-DTPA administration . 9 of 16 cases were located in lateral ventricle, 2 were in septum pellucidum, and the rest 5 were in fourth ventricle ,third ventricle ,prepontine cistern, right CPA and chiasmatic cistern respectively. In one case , CT showed isodensity and was enhanced in CE-CT,the lesion was situated in fourth ventricle. In all 17 cases, 11 were accompanied with microcystic structures. Conclusion Intracranial subependymomas are best delineated by MR imaging. The diagnosis of intracranial subependymomas should be considered when above findings are confronted.

Objective To summarize the study on the feasibility of celiac axis ligation. Methods Literatures about celiac axis ligation were reviewed retrospectively. Results Celiac axis branches included common hepatic artery, splenic artery, left gastric artery which had many variation and collateral flow between celiac and mesenteric vessels by gastroduodenal artery and pancreaticoduodenal artery. Celiac axis could be possibly ligated without obvious complications in patients who had celiac axis injuries, celiac artery aneurysms, upper gastrointestinal haemorrhage, excision of carcinoma around the celiac axis and portal hypertension. However, gallbladder necrosis or perforation, focal infarction of the liver even higher mortality had also been reported. Conclusion Celiac axis ligation should not be performed routinely, but it is surgically possible and may be a life saving approach in certain circumstances.

Objective To investigate the internal relationship between the exp ression of inducible nitric oxide synthase (iNOS) and the activation of NF－? B p65 in the skin of patients with psoriasis vulgaris(PV) and their roles in the p athogenesis of PV. Methods The expression and distribution of iNOS and NF－? Bp 65 were studied by in situ hybridization and immunohistochemistry in 20 patients with PV and 12 healthy controls. The severity of PV was assessed by Psoriasis a nd Severity Index(PASI) score. Results① The expression of both iNOS mRNA and pr otein was significantly higher in lesional epidermis than those in non lesiona l epidermis and epidermis of the controls (P

Objective:To research the expression of HBsAg DNA vaccine in immunized mice.Methods:The expression of HBsAg DNA vaccine was detected by immunohistochemistry staining in muscle fibers,lymphoid nodes and spleens of mice after intramuscular injection.Anti-HBsAg antibody was assayed by ELISA and the proliferation of spleen cells was measured by MTT.Results:The positive expression was observed in the tissues mentioned above.The titer of serum antibody showed positive results.Spleen cells could be proliferated by stimulating with HBsAg or ConA.Conclusion:The positive expression and certain kinds of immune responses have been shown in immunized mice.

Objective To investigate the internal relationship between the expression of inducible nitric oxide synthase (iNOS) and the activation of NF-κ Bp65 in the skin of patients with psoriasis vulgaris(PV) and their roles in the pathogenesis of PV.Methods The expression and distribution of iNOS and NF-κ Bp65 were studied by in situ hybridization and immunohistochemistry in 20 patients with PV and 12 healthy controls.The severity of PV was assessed by Psoriasis and Severity Index(PASI) score.Results ① The expression of both iNOS mRNA and protein was significantly higher in lesional epidermis than those in non-lesional epidermis and epidermis of the controls (P<0.01).Weak exprssion of iNOS mRNA was found in basal cell layer in a small number of healthy controls, however, strong expression was observed in entire basal cell layer and focal parts of prickle cell layer in all PV epidermis.② There was significantly positive correlation between iNOS and NF-κ Bp65 protein expression in lesional epidermis (P< 0.01).③ There was significantly positive correlation between the level of expression of iNOS mRNA in lesional epidermis and PASI score of patients (P< 0.01).Conclusions The expression of iNOS and NF-κ Bp65 is markedly increased in lesional epidermis of patient with PV.The activation of NF-κ B probably takes part in the pathogenesis of PV.High-level expression of iNOS may be due to the activation of NF-κ B.

In this article , the hot ethical concerns related to totally endoscopic thyroidectomy have been ana-lyzed and discussed .The author considers that this procedure is consisted with the patient′s no-harm and advanta-geous ethical principles , and the patient′s privacy is well protected .However , different procedures and operative risks should be well understood by the patients before the operation .Patient′s independence should be respected .

Objective To explore the role of Th17/IL-17 in the pathogenesis of asthma in children.Methods Thirty asthma children (asthma group) and 20 healthy volunteers (control group) were selected as our subjects.Percentage of Th17 cell in peripheral blood mononuclear cell (PBMC) of asthma children was detected by flow cytometry,the level of IL-17 and IgE in plasma were examined by enzyme linked immunosorbent assay.Results Proportion of Th17 cells in PBMC of children in asthma group was (1.83 ± 1.01) ％,significantly higher than that in control group ((1.02 ± 0.49) ％ ; t =3.896 ; P ＜ 0.01).The IL-17 level in control group was (19.11 ± 3.23) ng/L,significant lower than that in asthma group ((34.23 ± 4.88) ng/L;t =6.261 ;P ＜ 0.01)).The Ig E level in asthma group was (399.4 ± 45.1) ng/L,significantly higher than in control group((58.2 ± 19.7) ng/L;t =7.244,P ＜0.01).The level of IL-17 in plasma had a postive relationship with the proportion of Th17 cells(r =0.882,P ＜0.01),but not relationship was seen with the level of IgE (r =0.375,P ＜ 0.05).Conclusion Th1 7 cell is associated with asthma development of children,and the reason may due to probably aggravating asthma condition through increasing inflammation secreting IL-17.
