OBJECTIVETo study the antalgic and antiphlogistic functions and mechanism of ronggudingtong (RGDT) plaster (traditional Chinese medicine).

METHODSThe painful models were established with hot plate test or acetic acid writhing and the inflammatory models were established with daubing dimethylbenzene on auricle or injecting formaldehyde in toe or synovial envelope to study the antalgic and antiphlogistic functions of RGDT Plaster. The total protein and leukotriene B4(LTB4) in inflammatory exudate were detected to investigate the antalgic and antiphlogistic mechanism of RGDT plaster. The mice were randomly divided into different groups (n = 11), on the basis of drug using, the indexes of pain threshold, swelling degree were observed. Sixty-six mice were used to establish gasbag synovitis model and randomly divided into normal control group,model control group, positive control group (Voltaren gel 0.8 mg/d)and low/medium/high dosage RGDT plaster treating groups(30 mg/d, 60 mg/d, 120 mg/d).

RESULTS30 mg/d, 60 mg/d,120 mg/d RGDT plaster could upgrade the pain thresholds, remit auricular and foot swelling (P < 0.05, P < 0.01), and degrade total protein and LTB4 in inflammatory exudates (P < 0.05, P < 0.01).

CONCLUSIONRGDT plaster has some antalgic and antiphlogistic functions, and one of the mechanisms is depressing synthesis of LTB4.

OBJECTIVETo investigate the protective effects of Yuyin Ruangan Decoction(YRD, traditional Chinese medicine) on experimental hepatic injury in mice.

METHODSThe mice were randomly divided into control group, model group and YRD low, middle and high dose group(n = 11). By ip injection of D-GalN, CCk or thioacetamide (TAA), three models of hepatic injury mice were established to investigate the effects of YRD through detecting the indexes of liver function in serum and, the content of antioxidant system in the hepatic tissue.

RESULTSYRD could decrease the content of alanine aminotransferase (ALT)and aspartate aminotransferase (AST) in serum and that of malonaldehyde (MDA) in the hepatic tissue, upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the hepatic tissue. Furthermore, the above effects were dosedependent in a certain degree. CoNCLUSION: YRD has some protection effects on the model of experimental hepatic injury in mouse.

OBJECTIVETo establish and evaluate a mouse model of bronchial asthma with Yin deficiency syndrome.

METHODSThe mouse model of bronchial asthma with Yin deficiency syndrome was established by the treatment with injecting ovalbumin (OVA) two times to sensitize, inhaling OVA 14 times to stimulate, and using thyroxin through lavage during late stimulation. This model was evaluated through body weight, asthmatic behaviors, respiratory function, autonomous activity, lung pathology, and pulmonary fluid clearance.

RESULTSOVA combined with thyroxin was an appropriate method to induce the mouse model with increased food and water intake, autonomous activity, asthmatic behaviors score, and respiratory rate, decreased body weight, tidal volume, and wet/dry ratio of lung, and changed with pathology of lung tissue. The changes of the above mentioned parameters indicated that the model was the bronchial asthma with Yin deficiency syndrome.

CONCLUSIONThe OVA combined with thyroxin is a good pattern to establish a mouse model of bronchial asthma with Yin deficiency syndrome successfully, which can highly simulate the clinical symptoms of this disease.

Objective:To analyze the distribution characteristics of IL-13 gene rs20541C/T site polymorphism in Guangxi population and compare the distribution differences among different populations.Methods: IL-13 genotypes were examined by using SNaPshot technique and DNA sequencing in 275 Guangxi people and analyzed the distribution frequencies of allele and genotype in this site.The result compared with the allele and genotype of other populations(Europeans,Beijingers,Japanses and Africans).Results:The polymorphism of rs20541C/T of IL-13 gene in Guangxi population existed.The genotype frequencies of CC,CT and TT were 40.0%,46.2% and 13.8% respectively.The frequencies of C and T allele were found to be 63.1% and 36.9%.The polymorphism had no significant difference between male and female(P>0.05).Compared rs20541C/T of IL-13 gene with those of HapMap-CEU, HapMap-YRI and Tianjin people,the distribution frequency of genotypes was significantly different(P<0.05).In this site,there were significant differences of allele frequency when compared with the other five populations(P<0.05).Conclusion: There are different degrees of diversity of rs20541C/T polymorphism of IL-13 gene among different races and regions.

AIM:To investigate the distribution characteristics of interleukin-22(IL-22)gene rs2227485C/T and rs2227491A/G polymorphisms in Guangxi people and the distribution differences with other ethnic groups ,and to ex-plore the difference levels of common lipid indexes in different genotypes.METHODS:SNaPshot technique and DNA se-quencing were used in 280 Guangxi persons to examine IL-22 genotypes and to analyzed the distribution frequencies of allele and genotype in these sites.The distribution frequencies in different sexes ,and the differences between groups and diffe-rence levels of common lipid indexes in different genotypes were analyzed statistically.RESULTS:Three genotypes of CC ,CT and TT were found in rs2227485C/T with the frequency distribution of 17.1％,49.3％and 33.6％,respectively.No significant difference between different sexes of each genotype and allele frequency in the Guangxi population was observed(P>0.05).Compared with the distribution frequencies of genotype and allele in HapMap -TSI,HapMap-HCB,HapMap-JPT and HapMap-MEX,those in Guangxi population showed statistically significant differences(P<0.05).Three geno-types of AA,AG and GG were found in rs2227491A/G with the frequency distribution of 16.1％,52.8％and 31.1％,re-spectively.There was no significant difference between different sexes of each genotype and allele frequency in the Guangxi population(P>0.05).The significant differences of genotype frequencies among Guangxi population ,HapMap-TSI,Hap- Map-JPT and HapMap-MEX were detected(P <0.05 ).Compared with the other 4 populations ,allele frequencies in Guangxi population had significant difference(P <0.05).There were significant differences in the levels of HDL-C and LDL-C among the 3 genotypes of rs2227491A/G.The level of HDL-C had difference between AG/AA genotype and GG genotype.In addition,the level of LDL-C had difference between AG/GG genotype and AA genotype(P<0.05).CON-CLUSION:rs2227485C/T and rs2227491A/G polymorphisms of IL-22 gene have differences in different populations.The rs2227491A/G polymorphism may be associated with serum lipid levels.
