1.FHIT gene and tumor
Journal of International Oncology 2013;40(8):563-566
The human fragile histidine triad (FHIT) gene is a tumor suppressor gene,which is located at chromosome region 3p14.2.The fragile site FRA3B of the FHIT gene is the most unstable site.FHIT can promote apoptosis,and inhibit cell proliferation and tumorigenesis.High methylation status,loss of the various sections of the FHIT gene,changes of the fragile site FRA3B and abnormalities of FHIT transcripts can result in gene afunction,and then promote the development and progression of various types of cancers.Transfecting wild-type FHIT into tumor cells with low or lacking endogenous FHIT expression can induce apoptosis.The combined treatment with other genes may provide a new insight for the treatment of tumors.

AIM: To explore the effects of mindfulness- based stress reduction ( MBSR ) on anxiety, compliance and visual function in primary open angle glaucoma( POAG) patients. ·METHODS:Totally 64 patients, who were treated with topical medication and were diagnosed with POAG in the department of ophthalmology at Shaanxi Provincial People's Hospital, were randomly divided into the intervention group ( n=32 ) and the control group ( n=32 ) . Both groups received conventional mental health education while the intervention group was complemented with MBSR intervention. The patient's anxiety status, compliance rates and MD before and after the intervention were evaluated. ·RESULTS:After the MBSR intervention, the scores of HAMA of the intervention group were significantly lower than that of the control group (P<0. 01). The compliance of patients in intervention group was higher than that of the control group (P<0. 01). ·CONCLUSION:The MBSR intervention can effectively relieve the anxiety of patients and improve the compliance in primary open angle glaucoma patients. It can be promoted and put into clinical application.

Objective To study the effect of tetramethylpyrazine injection on proliferation and apoptosis of human acute lymphoblastic leukemia (ALL) cell line Jurkat and the relevant molecular mechanisms.Methods Cells were treated with tetramethylpyrazine injection at various concentrations (0,0.25,0.50,0.75,1.00,1.25 and 1.50 mg/ml),CCK-8 method was used to detect the inhibition rates at 24,48 and 72 h.After cells were treated with different concentrations of tetramethylpyrazine injection (0,0.50,1.00 and 1.50 mg/ml) for 48 h,the cell cycle and apoptosis were detected by flow cytometry,and the Aurora-B and Survivin protein expression were analyzed by Western blot.Results Compared with the control group (cells without tetramethylpyrazine injection treatment),various concentrations of tetramethylpyrazine injection could effectively inhibit Jurkat cells proliferation in a time-and dose-dependent manner (P < 0.05),and IC50 at 24 h,48 h and 72 h after treatment were (1.33±0.16),(0.91±0.10) and (0.67±0.11) mg/ml,respectively.After cells were treated with tetramethylpyrazine injection at different concentrations (0.5,1.0 and 1.5 mg/ml) for 48 h,the number of treated cells in G2/M phase was increased,but that in S phase was decreased,and the apoptosis rates were significantly higher than that of control group,with a dose dependence (P < 0.05).The results of Western blot showed that the expression levels of Aurora-B and Survivin in treated cells were lower than that of control group,also with a dose dependence (P < 0.05).Conclusions Tetramethylpyrazine injection can effectively inhibit proliferation and induce apoptosis of Jurkat cells in vitro,and its underlying mechanisms involve with down-regulation of the Aurora-B and Survivin protein expression.

Objective To investigate the relationship between methylenetetrahydrofotate reductase (MTHFR)C677T polymorphisms and H-type hypertension and increased plasma homocysteine (Hcy) levels. Methods From September 2013 to June 2014,4 012 permanent residents aged ≤30 year from 12 natural villages or communities in 6 regions of Hunan province were extracted according to the cluster random sampling method. Using computer random number table,571 residents were randomly selected as the research objects. According to the blood pressure and Hcy levels,571 residents were divided into 3 groups:a common hypertension group (n = 190),an H-type hypertension group (n = 94),and a normal blood pressure group (n = 287 ). Amplification refractory mutation system-polymerase chain reaction (ARMS-PCR)method was used to detect the MTHFR C677T polymorphisms in all the research objects and the penotyping was performed. Hcy levels were detected at the same time. Results There were significant differences in recessive model (CC + CT,TT)genotype frequencies among the H-type hypertension group (n = 66[70. 2%],n = 28[29. 8%]),common hypertension group (n = 156[82. 1%],n = 34[17. 9%]), and normal blood pressure group (n = 235[81. 9%],n = 52[18. 1%])(χ2 = 6. 797,P = 0. 033),and there were no significant differences in CC,CT,and TT genotype frequencies among the 3 groups (P >0. 05). In the recessive model,there were significant differences in TT genotype frequencies between the H-type hypertension group and the normal blood pressure group or the common hypertension group (χ2 = 5. 812,P = 0. 016;χ2 = 5. 212,P = 0. 022). There was no significant difference in TT genotype frequencies between the common hypertension group and the normal blood pressure group (P > 0. 05). The CC + CT and TT genotype Hcy levels of the MTHFR C677T recessive model in the H-type hypertension group were 17. 1 ±1. 6 and 19. 0 ±2. 9 μmol/ L respectively. There was significant difference between the genotypes (t = - 3. 115,P = 0. 004). The logistic regression analysis of MTHFR C677T recessive model genotype showed that after adjusting for sex and age,the residents with recessive model TT genotype had higher risk of H-type hypertension (OR,1. 946,95% CI 1. 172 -3. 232,P = 0. 01). Conclusion The TT MTHFR C677T gene mutation in this population may be an important genetic factor for the increased Hcy levels and the onset of H-type hypertension.

P53 gene (exon7~8) mutatins and p53 proteins and HPV 6,11,16,18-DNA were examined in 49 cervical carcinoma by immunohistochemistry, polymerase chain reaction (PCR) and single strand conformation polymorphism (SSCP) in order to investigate their role and mutual relation and clinical significance in the onco genesis of cervical carcinoma. The results showed that first, p53 proteins posit ive rate was 48.98%, and not outstandingly related to the differentiation and the invasive degree of cervical carcinoma(P>0.05); the defects of P53 gene (exon7~8) were not found but P53 (exon7~8) mutations were detected in 7 of 49(14.29%) cervical carcinoma; then, HPV16-DNA positive rate was much higher than HPV6,11,18-DNA positive rate respectively(P<0.001),and the different HPV-DNA was simultaneously tested in one cerv ical carcinoma; last, not all cases of P53 mutations had p53 proteins posi tive, but the cases of P53 mutations and p53 proteins negative certainly had HPV infections, and HPV positive cases were much more than its negative one in the cases of p53 proteins positive(P<0.001). These results proved that the oncogenesis of cervical carcinoma is mainly associated with HPV16 infections, and second related to P53 (exon7~8) mutations. p53 proteins positive results from P53 mutations or/and HPV infections in cervical carc inoma.
