0.05). In stratified studies, risk of asthma in individuals with null genotype of GSTM1 is 2.667 times of that with wild genotype after exposure to light air pollution. Risk of asthma in individuals living in heavy air pollution area is 2.125 time of that in light pollution area for all wild genotype of GSTM1 individuals, but without statistical significance. Conclusion It was not found that the relationship between GSTM1, GSTT1 polymorphism and asthma. Synergism of genotype of GSTM1, GSTT1 and air pollution was not also seen in this study.
3.Expression of Growth Arrest and DNA Damage Inducible Gene 45 ? during Preadipocyte Differentiation and Regulative Role of Tumor Necrosis Factor-Alpha
Journal of Applied Clinical Pediatrics 2006;0(17):-
Objective To investigate the changes of growth arrest and DNA damage inducible gene ?(GADD45?)expression during 3T3-L1 preadipocyte differentiation and analyze the regulative role of tumor necrosis factor-alpha(TNF-?) on GADD45? gene expression in matured 3T3-L1 adipocytes.Methods 3T3-L1 preadipocytes were cultured in vitro and differentiated into the matured adipocytes.TNF-? in different concentrations(0.1,1.0,10.0 ?g/L) was added into the culture medium of fully differentiated adipocytes(day 10) for various times(0.5,2,6,12,24 h).The levels of GADD45? gene mRNA expression were evaluated by reverse transcription polymerase chain reaction(RT-PCR).Results With the 3T3-L1 preadipocytes being differentiated into the matured adipocytes,the level of GADD45? gene mRNA expression was downregulated and reached the lower level in fully differentiated adipocytes.There was a significant difference between any 2 detected phases in the levels of GADD45? gene mRNA expression(P0.05).Treatment of day 10(3T3-L1) adipocytes with TNF-? of different concentrations resulted in a significant increase in the level of GADD45? gene mRNA expression.The induction effect of TNF? on GADD45? gene mRNA expression generally tended to be reinforced with the elongation of time course.Conclusions GADD45? gene may be involved in adipocyte differentiation and adipogenesis.TNF-? can upregulate the mRNA expression of GADD45? gene in matured adipocytes.The induction effect of TNF-? on GADD45? gene expression is generally(time-)correlated.

Objective To investigate the type of plasmid map of Y. pestis in the R. opimas natural plague loci in Junggar Basin. Methods A total of 39 plasmid DNA of Y. pestis which were isolated from the natural plague loci of Junggar Basin, Tianshan Mountain, Kunlun Mountain, Qinghai-Tibet Plateau and In-ner Mongolia were extracted by the methods of Kado and Liu. The plasmid map was analyzed by the methods of agarose gel eleetrophoretogram. Results Two types of plasmid map were found in 26 Y. pestis which were isolated from Junggar Basin. Of them 23 were 6 × 106, 45 × 106 and 65 × 106 type of plasmid map, and 3 were 6 × 106, 45 × 106 and 72 × 106 type. Conclusion There are two types of plasmid map in the R. opi-mus natural plague loci in Junggar Basin. One type, which is the dominant type in this area, is 6 × 106, 45 × 106 and 65 × 106 type. This type is also similar to the dominant plasmid map type of the nature plague loci of Tianshan Mountain, Kunlun Mountain, Qinghai-Tibet Plateau and Inner Mongolia. The other type is 6 × 106, 45 × 106 and 72 × 106 type, and this type is new plasmid map type of Y. pestis in our country.

Objective To explore the clinical efficacy and side effect of hepatocyte growth - promoting factor in treatment of infant hepatitis syndrome. Methods Sixty one cases of infant hepatitis syndrome were chased as the treatment group who hospitalized in our hospital from March 2002 to Feb 2003,and 54 cases of infant hepatitis syndrome as control group who hospitalized during March 2001 to Feb 2002. The treatment group were administrated with hepatocyte growth - promoting factor for 2 weeks. We obser-ved the recovery of patient's liver function (TBIL.ALT, AST) and the side effect of hepatocyte growth- promoting factor after two weeks of the treatment. Results After the treatment,TBIL and ALT decreased significantly in the treatment group of infant hepatitis syndrome. The treatment group was superior to the control group (P

Objective To explore the relationship between tumor necrosis factor(TNF)-? promoter G238A,G308A and interferon(IFN)-?+874A/T polymorphism and susceptibility to cytomegalovirus(CMV) hepatitis.Methods A TaqMan fluorescence polymerase chain reaction(PCR) in the IFN-?+874A/T and TNF-? gene promoter region single nucleotide polymorphism was tested in the subjects,including 87 infants with CMV hepatitis and 89 children without CMV hepatitis.Results No evident difference of TNF-? +238G/A and+308G/A allele frequency was found between infants with CMV hepatitis and controls.The cases of IFN-?+874 AA,AT and TT genotype were 64,20,3 cases in the infant CMV hepatitis group,and 45,26 and 18 cases in the control group,respectively.There was significant difference in IFN-?+874 allele genotype and frequency between infants with CMV hepatitis and the control group(P=0.001,P

With IL-6R as target, a new compound 2460A was identified from fungus using HTS screening model. The taxonomics of the produced strain was confirmed to be Trichoderma hazianum rifai after sequencing analysis of rDNA-ITS (internal transcribed spacer). Results showed that this compound has a binding activity on IL-6R competed with IL-6, thus it is a new ligand of IL-6R originating from microbe. With MTT assay, the anti-tumor activities of 2460A were demonstrated on CM126 and HT-29 cell lines separately, the IC50 are 2.17 x 10(-5) mol x L(-1) and 1.8 x 10(-5) mol x L(-1) respectively. The compound affected lightly the HT-29 cell cycle at S phase. Studies for the anti-tumor activity of 2460A in vivo are in progress in our lab.
