[DRD2/ANKK1 Taq IA polymorphism and early infant temperament].

Objective: To investigate whether there is an association between DRD2/ANKK1 Taq IA polymorphism and early infant temperament.

Methods: DRD2/ANKK1 Taq IA polymorphism (rs1800497) was determined using polymerase chain reaction-ligase detection reaction (PCR-LDR) techniques in 149 Chinese Han infants from Changsha City. Their mothers were asked to complete the Early Infant Temperament Questionnaires (EITQ) when the infants were 1 to 4 months old (mean: 2.

[Relationship between the levels of estradiol and monoamine neurotransmitters and postpartum depression].

Objective: To explore the relationship of estradiol (E(2)), monoamine neurotransmitters 5-hydroxytryptamine (5-HT), dopamine (DA) and postpartum depression.

Methods: Totally 342 women within 42 days after childbirth were assessed with Edinburgh postnatal depression scale (EPDS), Beck depression inventory (BDI), and general health questionnaire (GHQ). Above or equal to 13 of overall score of EPDS was the diagnosis standard of postpartum depression, and the women tested were divided into depression group and normal group accordingly, using the reagent box of radio immunoassay to test estradiol and 5-HT and DA level in the serum.

[Meconium-stained amniotic fluid and intra-amniotic infection].

Objective: To explore the relationship between meconium-stained amniotic fluid and Fifty-six women of cesarean section with intact membrane and intra-amniotic infection.

Methods: without parturient were divided into 3 groups according to the property of amniotic fluid (no meconium, I to approximately II degree meconium stainedness, and III degree mecomium stainedness). The content of interleukin-6 in amniotic fluid was measured with ELISA.
