Objective To investigate the influence of different intervention models on autism spectrum disorder (ASD) children. Methods Eighty-eight children aged from 12-46 months and newly diagnosed ASD were randomly assigned to different intervention models, including standard intervention group (T1, n=55), non-standard intervention group (T2, n=11), and family intervention group (T3, n=22). The intervention data was recorded including time and methods. Chinese revised version of Psycho-Educational Profile (C-PEP) and social adaptive behavior scale were used to test the development quota?tion (DQ) before and after intervention. Results There were significant statistical differences in C-PEP scale and pathologi?cal score before and after intervention in T1 group (P<0.01). There were significant differences in the pathological score, in?terpersonal and cooperative behaviors, sensory patterns and language barriers after intervention in T2 group (P<0.05). And there were no significant changes in the developmental quotient. The perception, gross motor, cognitive performance and the developmental quotient of oral cognition were significantly reduced after the intervention in T3 group (P<0.05). There was no significant change in pathology score. Results showed that there were significant differences in the imitation, perception, cognitive performance, oral cognition and general development before and after the intervention between three groups ( P<0.05). Conclusion A significant effect is found in children with autism spectrum disorder after standard intervention.

Objective: To study the protective effect of glutamine on intestine in mice damaged by radiation. Methods: Mice were exposed to 137 Cs rays (dose of 4Gy) with the whole body. The protetive effects of glutamine on intestine radiational damages were studied. Result: After radiation, GSH contents, SOD activities, protein and DNA contents were decreased and MDA contents were increased in intestinal mucosa. Villus height was shortened, crypt depth was deepened, wall width and villus surface area were decreased. Glutamine supplement restrained the changes of indices above mentioned and made them close to normal levels. Conclusion: Glutamine supplement had the protective effect on radiation damage in mice.

OBJECTIVE:
To explore the feasibility of detecting of Y-STR of fetal DNA in maternal plasma using Ion Torrent PGM™ System.
METHODS:
A total of 16 fetal DNA samples from maternal plasmas (8 cases from 38 weeks gestational age and 8 ones from 12 weeks) were prepared and a multiplex assay with 7 STR loci (DYS390, DYS391, DYS393, DYS438, DYS437, DYS456, DYS635) was designed for multiplex-PCR amplification. Using Ion Torrent PGM™ System, the results of Y-STR sequences and capillary electrophoresis were obtained and compared.
RESULTS:
Y-STR specific alleles were detected in the maternal plasma of all the pregnant women having male babies of second and third trimester, which were higher than that detected by capillary electrophoresis. Consistent Y-STR genotypes were observed between fetal DNA from maternal plasma and genomic DNA from the newborn babies.
CONCLUSION
Based on Ion Torrent PGM™ System, the prenatal Y-STR detection method may provide a high-sensitive and high-throughput choice for prenatal STR detection in forensic testing.

AIM:To make compound demethycantharidin(including Radix astragali and Rhizoma bletillae) into stomach remaining-floating sustained-release preparation. METHODS:Radix astragal and Rhizoma betillae pulverized to superfine powders were combined with hydrophilic gel to manufacture stomach remaining-floating sustained-release tablet(floating tablet). RESULTS:The tablet started to drift in 3 min in the artificial gastric juice and float lasted for more than 8 h. By isotopic tracering,the floating tablets given on an empty stomach were retarded for 2-3 h and on large meal for 4-5 h in combination with ordinary tablet only retarded for 1 h. A pharmacopoeia dissolution method was set up to determine the release. 50% of tablets were disintegration in 5 h,70% in 8 h. The t 1/2 was 5.1 h(2-4 h for ordinary tablets),and the MRT was 8.3 h(3.3 h for ordinary tablets),and the remaining-floating sustained-release tablets showed a relative bioavailability of 230.71%. CONCLUSION:Pretreatment of raw herbs from compound demethylcantharidin and selection of the excipients will help to produce the herb-containing floating tablet.

10.Regulation of NOD like receptors and inflammasome during the inflammation.
Acta Physiologica Sinica 2012;64(6):741-750
The innate immune system plays a crucial role in the rapid recognition and elimination of invading microbes. Detection of microbes relies on germ-line encoded pattern recognition receptors (PRRs) that recognize essential bacterial molecules, so-called pathogen-associated molecular patterns (PAMPs). A subset of PRRs, belonging to the nucleotide binding oligomerization domain (NOD)-like receptor (NLR) families, detects viral and bacterial pathogens in the cytosol of host cells and induces the assembly of a multi-protein signaling platform called the inflammasome. The inflammasome serves as an activation platform for the cysteine protease Caspase-1, a central mediator of innate immunity. Caspase-1 initiates a novel form of cell death called pyroptosis. Inflammasome activation by pathogen-associated signatures results in the autocatalytic cleavage of Caspase-1 and ultimately leads to the processing and thus secretion of pro-inflammatory cytokines, most importantly interleukin (IL)-1β and IL-18. Here, we review the recent advancements of negative regulatory functions and mechanisms leading to the activation of NLRP1, NLRP3, NLRC4, and AIM2 inflammasomes.
