title: [Relationship between gene p53 codon 72 polymorphism and pathological scar formation after caesarean section].
abstract: OBJECTIVE
  To study the relationship between gene p53 codon 72 polymorphism and pathological scar formation occurrence after caesarean section.
  
  
  METHODS
  The method of molecular beacon with real-time PCR was applied to detect gene polymorphism of p53 codon 72 in blood samples taken from 303 pregnant women (within a week after caesarea section). The clinical visits were taken 3 times for 12th to 18th months to ascertain clinical formation of pathological scar and its relationship to genotype of p53. The chi-square method was used to analyze the relationship of p53 gene polymorphism and abnormal scar formation occurrence by statistical software SPSS 13.0.
  
  
  RESULTS
  Total of 303 pregnant women were assayed. 30 patients were found with pathological scar by clinical visit in the total 303 pregnant women. The genotype frequencies of total three types (C/C, C/G and G/G) of p53 gene codon 72 in patients with pathological scar are significantly different from that of normal pregnant woman. The frequency of C/C genotype in patients are higher than that of normal pregnant women (P < 0.01). The frequency of C/C genotype in these patients with pathological scar is higher (46.7%, 14/30) than C/G (33.0%, 10/30, P < 0.01) or G/G (20%, 6/30) genotype (P < 0.01). The C allele frequency in the patients is 63.7%. It is also higher than G allele (36.7%, P < 0.01). The OR value is 2.30. Therefore the C allele of p53 gene codon 72 is a risk factor for pathological scar.
  
  
  CONCLUSIONS
  There was a certain relationship between p53 gene codon 72 C allele and pathological scar formation after caesarean section.
