Object To investigate the correlation of IGF-2 exon 9 CpG island methylation and the expression of IGF-2,and further explore the mechanism of Wilms tumor. Methods The IGF-2 exon 9 methylation status and IGF2 gene expression in 42 cases of Wilms tumor and corresponding normal tissues were detected by using methylation-sensitive restriction enzyme PCR and allele-specific IGF2 gene expression analysis.Results IGF-2 exon 9 methylation rate was 15% in W ilms tumor group, and 97% in normal tissue group. The difference was significant (P < 0.01), and the difference in pathological type was also significantly different (P < 0.01). Exon 9 unmethylated tissues showing biallelic expressions of IGF-2 were significantly higher than that of methylated tissues (P < 0.05). Conclusion IGF-2 exon 9 unmethylation may be the cause of biallelic expression of IGF, which contritues to tumorigenesis in Wilms tumor.

This study was aimed to investigate the distribution of tumor necrosis factor-alpha (TNF-alpha)-308 gene polymorphism and its correlation with asthma in TCM syndromes between Han and Uyghur People in Xin-jiang. The polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) method was applied in the detection of TNF-alpha-308 gene polymorphism among 160 bronchial asthma cases and 40 healthy con-trols. Traditional Chinese medicine (TCM) syndrome differentiation standard on bronchial asthma was applied in the syndrome differentiation of 160 bronchial asthma cases. And gene distributions of TCM syndrome differentia-tion were compared. The results showed that there was no significant difference between the genotypes (wild-type and mutant) and allele distribution between the asthma group and the normal control group, the Uyghur asthma group and Uyghur normal control group, the Han asthma group and Han normal control group, Uyghur normal control group and Han normal control group (P > 0.05). There was no significant difference on the TNF-alpha-308 genotype distribution among different TCM syndromes. There was no significant difference on TCM syndrome distribution between Han asthma patients and Uyghur asthma patients. It was concluded that bronchial asthma in Xinjiang may be nothing to do with ethnic group, TNF-alpha-308 gene polymorphism. And the bronchial asthma syndrome differentiation type may be nothing to do with the TNF-alpha-308 genotype distribution.

Background The incidence of primary open angle glaucoma (POAG) is increasing in recent years.To study the risk factors of POAG pathogenesis is of great significance.Objective This study was to explore the association between Helicobacter pylori infection and POAG pathogenesis.Metbods The Chinese and English literature about Helicobacter pylori infection and pathogenesis from January 2000 to February 2015 was searched in PubMed,Embase,The Cochrane Library,VIP,Wanfang database and CNKI database with computer and supplemented by the relevant references,and these cases-control studies were evaluated using the Newcastle-Ottawa Scale (NOS).The odds ratio (OR) and 95％ confidence interval (CI) were calculated by using Stata 12.0 statistical software.Sensitivity analysis and subgroup analysis were used to process the heterogeneity (I2) among the studies.The effect size was analyzed using the randomized model in I2 ≥50％ and fixed model was used in I2＜50％.Results Eight cases-control studies from Erope,Asia and North America were included with the NOS scores ≥ 5.The examination methods for Helicobacter pylori included ELISA,Western blot and histopathology among the articles.Helicobacter pylori infection rate was 71.38％ (197/276) in the POAG group,and that in the control group was 42.90％ (151/352).Randomized model analysis showed a significant association between Helicobacter pylori infection and POAG pathogenesis (OR =3.23,95％ CI:1.65-6.23,P =0.001).No obvious interference from any paper was found by sensitivity analysis.The subgroup analysis based on different areas found that Helicobacter pylori infectious rate of POAG patients was highest in Europe area (OR =7.25,95 ％ CI:3.61-14.54,P =0.000,I2 =0.0％),the subgroup based on different detect methods found that histopathological examination had the highest detected rate of Helicobacter pylori (OR=9.13,95％ CI:3.78-22.04,P=0.000,I2 =0.0％),and the next was ELISA assay (OR=2.85,95％ CI:1.40-5.81,P =0.004,I2 =60.4％).No published bias was seen by funnel plots and Egger linear analysis.Conclusions Helicobacter pylori infection is associated with POAG pathogenesis.

AIM　To study the pharmacokinetics of 20(R)-ginsenoside Rg3 (GRg3) in human. METHODS　High-performance liquid chromatography-ultraviolet detection method was used in this study. RESULTS　The pharmacokinetics of GRg3 in 14 healthy volunteers were investigated. After a single oral dose of 3.2 mg.kg-1 in 8 male volunteers, the plasma concentration-time course fitted well to a two-compartment open model, with the following pharmacokinetic parameters: Tmax (0.66±0.10) h, Cmax (16±6) ng.mL-1, T1/2α (0.46±0.12) h, T1/2β (4.9±1.1) h, T1/2(Ka) (0.28±0.04) h, AUC0-∞ (77±26) ng.mL-1.h. No kinetic analysis was made after an oral dose of 0.8 mg.kg-1 GRg3 in 6 other volunteers because of the low concentration, but a good correlation between Cmax and dosage of the two groups was found. CONCLUSION The absorption of GRg3 was rapid in man, and its elimination was rapid after oral administration of ginsenoside Rg3. The pharmacokinetic results shows that it exhibited first order kinetic characteristics.
