2.The pediatric epilepsy surgery in China
Neurology Asia 2007;12(Supplement 1):33-35
There is rapid growth of pediatric surgery service in China in the recent years. A survey by the China
Association �A gainst �Epi�lepsy underta�ken in �June ����� 2006���� on the ma�jor cities in different parts of the
country showed a dramatic increase particularly in years 2004 and 2006. Surgery for temporal lobe
epilepsy accounts for half of the operation. Surgery has an important role in the treatment of drug
resistant pediatric epilepsy. With large population and vast geographical spread, it is important to
further develop pediatric epilepsy surgery service in China

Objective Helicobacter pylori (H. pylori )contains more than 30 genes and many of them in cag pathogenicity island (cag PAI) composed of cag Ⅰ and cag Ⅱ are involved in eliciting the transcription of interleikin 8 (IL 8) and the induction of IL 8 protein secretion in gastric epithelial cells, although some genes are not involved. This study was designed to observe the effect of ORF10 of H. pylori cag Ⅱ on the transcription of IL 8 in gastric epithelial cells and to test the possibility that certain genes in the cag PAI also downregulate (modulate) the transcription and expression of IL 8 in gastric epithelial cells. Methods Three strains of H. pylori mutants with deletion of ORF10 gene (ORF10, namely 28 1, 28 2, 28 3) and L5F11 cells containing IL 8 reporter gene were constructed. The constructed L5F11 cells were co cultured with the above strains and the luciferase activity (IL 8 transcription) was measured in a scintillation counter and the concentration of IL 8 protein was assayed by enzyme linked immunosorbent assay (ELISA). Results The activities of luciferase induced by 3 strains of H. pylori mutants with deletion of ORF10 gene were much higher than that of the mother strain 26695 [ 28 1:(1.49 ? 0.27)?10 6 cpm vs. (0.67 ? 0.08 )? 10 6 cpm, P

Objective To investigate the resistant status and to type the phenotype and plasmid profiles of prevalent gonococcal strains. Methods A total of 98 gonococcal strains isolated from 1998 to 1999 in Zhanjiang was identified systemically. The susceptibilities of 98 strains of gonococci to penicillin,tetracycline and ciprofloxacin were detected by agar dilution method. The β - lactamase production was tested by iodometric method. The plasmids were extracted by alkaline lysis technique. Results The prevalence of gonococcal strains resistant to penicillin, tetracycline and ciprofloxacin were 22.44% ,45.94% and 55.12% ,respectively. There were 6 positive strains for β - lactamase, accounting for 6.12% (6/98). The most common phenotypes were susceptiblePT、 CMRNGT、 CMRNGPT and TRNG, accounting for 43.86% ,23.46% ,10.20% and 10.20% ,respectively. The detection rate of plasmids were 91.84% .Among them, the percentages of 42.5 kb,39.5 kb,7.4 kb and 4.2 kb plasmids accounted for 11.22% ,41.82% ,59.16% and 67.32% ,respectively.There were 12 types of plasmid profiles(PP), the predominant types were 7.4kb+ 4.2kb and 39.5kb+ 7.4kb+ 4.2kb, accounting for 21.42% and 17.34% ,respectively. Conclusion The gonococcal strains resistant to ciprofloxacin are very high in Zhanjiang. The phenotype and plasmid profiles of the strains have characteristic distribution.

Objective To explore the diagnostic and therapeutic value of endoscopic retrograde cholangiopancreatography ( ERCP) in teenagers with chronic pancreatitis. Methods Thirteen teenagers with chronic pancreatitis diagnosed and treated by consecutive ERCP procedures in our hospital from Feb 1997 to Feb 2002 were studied retrospectively. Results Of the 13 patients 12 had abdominal pain and 10 had history of acute/chronic pancreatitis. The ERCP findings were as follows: pancreatic duct stricture and/ or dilation 12, pancreatic duct stones 7, pancreatic pseudocysts 2, pancreas divisum 3, and cholecystolithia-sis 1. Therapeutic interventions included EST 7 , basket stone extraction 6, placement of pancreatic duct stent 5 , pancreatic duct stricture bougie or balloon dilation 4, accessory papillotomy 2 and endoscopic papillary dilation 1. In the 6 - 68 months follow - up, 11 (84. 6% ) never had recurrence of pancreatitis or abdominal pain ,2 patients had no abdominal pain after the second ERCP procedure. There were procedure -related complications of hyperamylasemia in 4 cases(30. 8% ) and pancreatitis in 3 cases(23. 1% ). Conclusion ERCP has significant value in diagnosing and treating chronic pancreatitis in teenagers, but has a rather high rate of complication . It suggested that the restrict selection of indication and safe application of the procedures in pediatric patients may be expected to decrease the adverse events of ERCP.

Rough set is a mathematical approach to study imprecise, uncertain or incomplete information or knowledge. The data mining technology based on the rough set theory can be trained through the training data set. The technology is applied to such fields as the prognosis of the pain in the chest, emergence diagnosis in ICU, distinguishing and diagnosis of lung tumor and rheumatoid disease, diagnosis of galactophore disease, diagnosis of premature birth, classification and diagnosis of liver disease and acute appendicitis. The technology has a brilliant future in medical data mining.

Objective To investigate the impact of angiotension II (Ang II ) on the activation of nuclear factor-kappaB (NF-?B) signaling transduction pathway in cultured rat pancreatic stellate cells (PSCs). Methods Growth-arrested rat PSCs were incuhated for indicted time intervals with increasing concentrations of Ang II . The DNA binding activity of NF-?B was determined using electrophoretic mobility shift assay (EMSA). Western blot analysis was used to examine the degradation of inhibitory proteins of NF-?B (I?Bs). Expression of monocyte chemoattractant protein-1 (MCP-1) mRNA and protein were assessed by Northern blot and enzyme-linked immunosorbent assay (ELISA), respectively. Results Treatment of cells with Ang II led to a biphasic activation of NF-?B, which peaked at 15 min and 6 h later, and it was correlated with differential degradation of I?B? and I?B?. Ang II -induced NF-?B activation was greatly inhibited by antioxidants pyrrolidine dithiocarbamate ( PDTC), diphenylene iodonium. and N-acetylcysteine, suggesting the involvement of oxidative stress in this process. In PSCs, Ang II induced a dose-dependent increase in the expression of MCP-1 and this effect was markedly inhibited by blocking NF-?B activation with MG132 and PDTC, indicating that Ang II -induced MCP-1 gene expression was NF-?B-dependent. Conclusion The present results suggest that Ang II , through an oxidative stress-dependent mechanism, may activate a functional NF-?B signaling pathway in PSCs, through which it may participate in pancreatic inflammation and fibrosis.

To observe the protective effect of somatostatin (SS) on gastric mucosa of rats.Methods: Before gastric mucosal lesion were made in rats by pure alcohol, SS was intravenously droppedand anti-SS serum was injected into the vein, and the change of ulcer index and the degree of gastric mu-cosal lesion were observed. Results: Ulcer index of the SS group was much lower than that of the controlgroup (P

To determine the role of GMBF in gastric mucosal tolerant cytoprotection under stress and its possible regulator, SD rats were exposed to repeated WRS, during which L NAME , a non selective NOS inhibitor, or L Arg, a substrate for NO synthesis, was administered to inhibit or promote the synthesis of NO, GMBF was measured using LDF 3 Flowmeter, NO level in gastric mucosa was monitored by Griess reaction, and gastric mucosal lesions were evaluated by UI. The results showed that gastric tolerant cytoprotection was accompanied by increased GMBF and NO level in gastric mucosa. Inhibition of endogenous NO synthesis by L NAME worsened mucosal lesions induced by WRS. After repeated WRS, adaptive increase of GMBF was abolished and NO content in gastric mucosa significantly reduced. In contrast, enhancement of endogenous NO synthesis by L Arg attenuated mucosal erosions produced by WRS and GMBF, NO content in mucosa increased. Good relationships between the changes in GMBF, UI, NO content in mucosa were found. It suggested that GMBF might play an important role in gastric mucosal tolerant cytoprotection. Endogenous NO might be one of its regulators. Inhibition of its synthesis delayed the induction of tolerant cytoprotection, while enhancementpromoted it.
