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.

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.
