OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.
METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.
RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.
CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

Objective To investigate the characteristics of mental rotation in stroke patients and the relationship between mental rotation and visual-spatial cognitive function. Methods From March, 2012 to October, 2013, 30 stroke patients were selected as experimental group and 30 healthy subjects as control group. They were tested with hand mental rotation task, and assessed with visuospatial abilities from Mon-treal Cognitive Assessment (MoCA). Results The reaction time of hand mental rotation task was significantly longer in the experimental group than in the control group (F=95.6, P<0.001). The reaction time was longer with the increase of rotation angle in both groups, and was the longest as 180° of rotation (F=345.672, P<0.001). The response accuracy rate of hand mental rotation task was significantly lower in the experimental group than in the control group (F=6.444, P<0.05). The response accuracy rate was lower with the increase of rotation angle in both groups, and was the least as 180° of rotation (F=102.911, P<0.001). The reaction time negatively correlated with the score of visuospa-tial abilities, while the response accuracy rate positively correlated with it in the stroke patients (P<0.05). Conclusion The mental rotation ability is impaired in stroke patients, however, the respondent pattern is similar to healthy people. The mental rotation ability is correlated with visual-spatial cognitive functions in stroke patients.

Objective Platelet activating factor(PAF),which has been implicated in the pathophysiology of inflammation in asthma,is degraded and inactivated by PAF acetlhydrolase(PAF AH).To investigate the association of PAF AH activity with genotype in asthmatic children.Methods We studied 57 asthmatic children and 30 normal controls. The plasma PAF AH genotype was detected as representative case with 3 different genotypes (Val/Val,Val/Phe and Phe/Phe) by allele specific polymerase chain reaction(AS PCR).The PAF AH activity in plasam was examined by the changes of substrate assay.Results In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group,and plasma PAF AH activition was absent 15.4 %.In another three groups plasma PAF AH activation were absent 2 %-3 %.There was significant difference of plasma PAF AH activity among 3 groups of genotype(Val/Val,Val/Phe and Phe/Phe).In the similar genotype, there was no significant difference of plasma PAF AH activity between the groups of control and asthma.Conclusions There was imbalace of PAF/PAF AH in asthmatic children. In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group. PAF AH(Val279Phe) gene mutation was related with plasma PAF AH activity.
