ObjectiveTo evaluate the effect of health education to women of childbearing age on knowledge of birthdefents.MethodsRandomly selected 200 case of maternal pre-pregnancy check-up in the hospital outpatient department were divided into two groups,The observation group of 100 cases,100 cases of the control group.the control group received rule progestation knowledge education,the observation group enforce health education intervention,apply the way of questionnaire survey,and the results were statistically analyzed.ResultsThe observation group answer correct rate is obviously higher than the control group ( all P ＜ 0.05 ).ConclusionTaking a variety of measures of health education for pregnant women during the physical examination for effective interventions,could significantly improve the population birth defects knowledge rate had positive significance to the prevention of birth defects.

Objectives To investigate the relationship of methylenetetrahydrofolate reductase (MTHFR) and methioninesynthase reductase (MTRR) with unexplained recurrent spontaneous abortion (URSA). Methods Case control study was used to select 244 patients with URSA (miscarriage group) and 116 normal women (control group) who were admitted to Tianjin Medical University General Hospital and Tianjin Women’s and Children’s Health Center from January 2013 to March 2015. The oral mucosal epithelial cells were extracted using fluorescence quantitative PCR to detect MTHFR gene C677T, A1298C and MTRR gene loci of A66G single nucleotide polymorphisms (SNP). The relationship between folate metabolism related gene polymorphisms of MTHFR and MTRR and URSA was analysed. Results The frequency of C677T genotype MTHFR was significantly higher in URSA group than that in the control group, and the frequency of CT genotype was significantly lower than that of the control group (P<0.05). There was no significant difference in the frequencies of A1298C MTRR and A66G MTHFR between the two groups. The activity of MTHFR, red cell folate and plasma folate levels were significantly lower in URSA group than those of control group. Homocysteine levels were significantly higher in URSA group than those of control group (P<0.05). There were no significant differences in serum folic acid, red cell folate, homocysteine cysteine levels between patients <35 years old and ≥ 35 years old in URSA group. Conclusion C677TMTHFR gene polymorphism is associated with unexplained recurrent spontaneous abortion.
