This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.

Methods The target gene(EGFP and GDNF) was cloned into baculovirus transfer vector pFastBacDual, pFB-EGFP-GDNF was constructed and restriction enzyme analysis was conducted. pFB-EGFP-GDNF was transposited with baculovirus shuttle vector (Bacmid) into DH10Bac competent cells, and recombination baculovirus vector Bacmid-EGFP-GDNF was constructed. The plasmid was extracted and PCR was performed for identification. Bacmid-EGFP-GDNF was transfected with Sf9 insect cell package virus by liposomal transfection method. Immunofluorescent staining was employed to detect the expression of EGFP and GDNF protein in St9 cells. Results The target gene fragment was correctly cloned into pFastBaeDual vector, and recombinant Bacmid was constructed. Bacmid-EGFP-GDNF was successfully transfected, and higher virus titer was obtained. The coexpression of GDNF and EGFP protein in Sf9 cells was identified by immunofluorescent staining. Conclusion The recombinant baculovirus Bacmid-EGFP-GDNF can be successfully constructed, and the protein of EGFP and GDNF is coexpressed in St9 cells, which paves a way for the research of GDNF gene therapy.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.

OBJECTIVETo investigate the changes of the goblet cells in the intestine during the restitution process of the gut barrier after hemorrhagic shock.

METHODSForty-nine Sprague-Dawley rats with body weight of 250-300 g were divided into control group (n=7) and experimental group (n=42). Rats in the experimental group was further divided into 6 groups (n=7 each) according to different time point at 1, 3, 6, 12, 24, and 36 hours after hemorrhagic shock resuscitation. The specimens from ileum tissue were taken to observe the morphological chan ges of the intestinal mucosa. The number of goblet cells was determined by light microscope and/or electron microscope. The contents of trefoil factor family 3 (TFF3) of goblet cells were examined using GC-9A gas chromatographic instrument.

RESULTSAfter hemorrhagic shock, mucosal epithelial injury was obvious in the small intestine. Tissue restitution was found after 3 hours, and mostly established after 12 hours. Following tissue restitution,the denuded mucosal surface was covered intensively by goblet cells. The number of goblet cells on the intestinal mucosa was reduced significantly from 243+/- 13 at 1 h to 157+/- 9 at 24 h (r=- 0.910, P< 0.01), and returned to normal level at 36 h. In the experimental group, the content of TFF3 in the intestinal mucosa increased significantly at 12 hours, decreased, but was still higher at 24 hours (t=3.24, P< 0.05).

CONCLUSIONSThe goblet cells play a key role in the restitution of intestinal mucosa. High expression of TFF3 may facilitate the intestinal mucosal restitution in the early phase.

To investigate epidemiologic feature and genetic variance of Sapovirus among children in China, fecal specimens were collected from children under 5 years old with acute diarrhea from Feb 2006 to Jan 2007 in nine provinces including Anhui, Fujian et al. A total of 1,110 fecal samples were detected for Sapovirus by reverse transcriptase-PCR (RT-PCR). Ten samples (0.9%) were positive for Sapovirus. The PCR products were then sequenced and analysed by phylogenetic tree. The results indicated that the detected Sapovirus strains were classified into two genogroups and three genotypes, including G I/1, G I/3, G II/3.
