Journal of International Oncology 2011;38(4):315-318
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.

Objective To observe the clinical efficacy of abdominal acupuncture plus moxibustion in treating cervical spondylosis of vertebral artery type.Method A hundred patients with cervical spondylosis of vertebral artery type were randomized into a treatment group and a control group, 50 cases in each group. The control group was intervened by abdominal acupuncture plus electroacupuncture; while the treatment group was by moxibustion in addition to the treatment given to the control group. After a treatment course, the onset and remission time of vertigo was observed, and the clinical efficacies were compared between the two groups.Result The total effective rate was 96.0% in the treatment group versus 93.8% in the control group, and the difference was statistically significant (P<0.05). There was a significant difference in comparing the onset and remission time of vertigo between the two groups (P<0.05). In comparing the relapse rates 3, 6, and 12 months after the intervention between the two groups, the difference were statistically significant (P<0.01).Conclusion Abdominal acupuncture plus moxibustion is an effective approach in treating cervical spondylosis of vertebral artery type.

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.

Objective We discussed the effect of body massage combined with massage of breast point (ruzhong point and rugen point) to facilitate the milk secretion, alleviate the swelling pain of breast, recover physical strength of mother, establishment of the confidence of breast feeding and increase the success rate of breast feeding. Methods We divided 212 parturients into the test group (104 cases) and the control group (108 cases). The test group received body massage combined with massage of breast acupuncture point based upon routine postpartum nursing. The control group received routine postpartum nursing We observed the time and volume of milk secretion in the two groups. Results The time of milk secretion of the test group was ahead of that of the control group and volume of milk secretion was increased in the test group than that of the control group (P<0.01). Conclusions Body massage combined with massage of breast point (ruzhong and ruzhong point) could place the time of milk secretion ahead, increase the volume of milk secretion. Besides, it could alleviate the swelling pain of breast and ensure the success d breast feeding.

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.

Glioblastoma(GBM)is one of the most common primary intracranial tumor that has high de-gree of malignancy ,invasive ability and a fatal prognosis .In recent years ,with the development of modern technol-ogy in biomedical sciences ,the understanding on GBM has developed gradually from pathological diagnosis to mo -lecular classifications ,which is based on the molecular characteristics of genetic signatures .Based on gene expres-sion and DNA methylation patterns , primary glioblastoma is divided into four subtypes , including the classical , neural,proneural and mesenchymal .These molecular classifications are closely relevant to the biological charac-teristics of glioblastoma .This review briefly introduces the molecular classifications of primary glioblastoma , but mainly focuses on the changes of the major genetic EGFR ,PTEN and PI3K,CDKN2A in the classical subtype of GBM,and discusses the treatment strategies for primary glioblastoma .

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.
