Objective To investigate the single nucleotide polymorphism of 5,10-methylenetetrahy-drofolate reduetase gene and its association with the treatment of methotrexate in rheumatoid arthritis (RA).Methods A total of 184 patients with RA were divided into methotrexate (MTX) treatment group, MTX+other DMARDs treatment group, and treatment with other DMARDs but not MTX group. The clinical and laboratory data were evaluated before treatment and 24 weeks later. Efficacy and toxieities of each medication were also analyzed. Real-time fluorescent quantitative PCR was conducted to test gene mutations in RA patients and 100 healthy controls. Results There was no significant difference in the frenqueney of 677CC,CT, "IT and 1298AA, AC, CC between RA patients and the healthy controls. There was significant difference in the frenqueney of 677CC, CT, Tr between RA patients with cardiovascular eomplieations and the healthy controls. In the MTX treatment group, there was significant difference in the frenqueney of 1298AC, CC between the group in which MTX was effective and the other groups in which MTX was not effective, the occurrence rate of side effects of MTX in the patients with 677TT was higher than those without mutation(CC).In MTX+other DMARDs group, the occurrence rate of side effects of MTX in the patients with 677TT and CT was higher than that without mutation (CC). Conclusion There is no relationship between the pathogenesis of RA and the 677C/T, 1298A/C mutation of MTHFR gene. MTHFR gene 677C/T mutation is probably one of the genetic risk factors for cardiovascular complications of RA patients and the side effects of MTX. MTHFR gene 1298A/C allel is associated with the efficacy of MTX.

Purpose:To detect the expression of MDR 1 / P-gp,C-erbB-2 in breast cancer and study the correlation between MDR 1 /P-gp and C-erbB-2. Methods:Expression of MDR 1 gene was measured with the flu orogenic quantitative RT-PCR method in 57 cases of breast cancer and 20 cases o f control group (including 10 cases of benign breast lesions and 10 cases of adj acent breast tissues). In addition, immunohistochemical analyses was used to det ect the expression of P-gp and C-erbB-2 protein in the above mentioned tissu es. Results:The amplification rate of MDR 1 gene and the expre ssion of P-gp protein in breast cancer group was 50.88% (29/57) and 42.11% (24/ 57), which had a significient difference as compared to the control group. The a mplification of MDR 1 gene were higher than the expression of P-gp protein ,there was close correlation between them but not complete correspondence.The p ositive rate was 28.07%(16/57) in detecting the overexpression of C-erbB-2 pro tein in breast cancer group, nevertheless, no positive case was found in the con trol group. The expression of MDR 1/P-gp was also correlated with the over expression of C-erbB-2. Conclusions:Multidrug resistance gene1(MDR 1)and protoonco gene C-erbB-2 were co-expressed in breast cancer,and their expression were po sitively related. The expression of above mentioned two genes have a relationshi p with multidrug resistance in breast cancer.

Objective To detect the hypermethylation of HOXB6 gene in gastric cancer tissue and investigate the relationship between the gene expression and the clinics.Methods seven types of gastric cancer cell line and 73 cases of gastric cancer biopsy tissues were measured by combined bisulfite restriction analysis method.The gene expression and the re-expression after demethylation were detected by RT-PCR.Results Of 7 cell lines examined, 4 showed hypermethylation.The methylating status of HOXB6 was found to be correlated with loss of expression,which was restored by 5-aza-2＇-deoxycytidine treatment.We also find hypermethylation in 20/73(27.40%)case of cancer tissues but no one in non cancer tissue.Conclusion There are close relationship between hypermethylation and gene silencing in the HOXB6 gene of gastric cancer,There are also a gene re-expression after its demethylation.Hypermethylation of HOXB6 gene can be a tumor marker for gastric cancer diagnosis,and the agent of demethylation maybe a new antineoplastic drug.

Objective We make a retrospective analysis , to compare to COPD group and discuss the risk factors and the clinical features in acute exacerbation in patients with ACOS to follow-up the exacerbating frequency after regular treatment in both two groups in one year. Methods There were 56 patients with ACOS and 80 patients with COPD from 2013 to 2015 in our hospital in 30%≤FEV1<80% in the stable phase. The common data of the enrolled patients included the age,sex,smoking, and allergic rhinitis or other allergic diseases in family. We analyzed laboratory index including PaO2,PaCO2,CRP,white blood cells,IgE of serums and compared the proportion of antibiotics,system used of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation and followed up exacerbating frequency after using ICS united LABA/LAMA. Results The age and smoking index in the ACOS group were lower than the COPD group (P < 0.05). The allergic rhinitis or other familial allergic diseases,lower age of 60,the high IgE in serum were risk factor, in ACOS. In acute exacerbation, the PaCO2,IgE and WBC in serum were higher than that of the COPD group(P <0.05). The midian length of stay in hosipital was 12 days in the ACOS group and 8 days in the COPD group. The proportion of antibiotics,systemic administration of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation in the ACOS group were higher than that of the COPD group (P < 0.05). The exacerbating frequency was decreased after using ICS united LABA/LAMA(1.2±0.6 vs 3.8±1.3,P < 0.05)in both ACOS and COPD groups. Conclusions The allergic diseases may participate in ACOS, in which it has familial tendency. In acute exacerbation, ACOS patients had even more inflammation and faster course than COPD patients. Using ICS united LABA/LAMA can reduce exacerbating frequency in ACOS.
