ABSTRACT: This study evaluated the effect of transvaginal ultrasound-guided embryo aspiration plus local administration of low-dose methotrexate (MTX) on caesarean scar pregnancy (CSP). Sixty-eight cases of CSP were randomly grouped for (1) systemic administration of MTX plus curettage with hysteroscopy (control group); and (2) transvaginal ultrasound-guided embryo aspiration plus local administration of low-dose MTX (experimental group). Serum β-HCG and transaminase levels, length of hospital stay, occurrence of hypoleukocytosis, vaginal bleeding and genital infection were analyzed. No statistical differences in the duration needed for β-HCG normalization, genital infection and length of hospital stay were observed between the two groups. However, the occurrence of massive vaginal bleeding, hypoleukocytosis and elevated transaminase levels were significantly lower in patients who received transvaginal ultrasound-guided embryo aspiration plus local administration of low-dose MTX compared with patients in the control group. Our study suggested that transvaginal ultrasound-guided embryo aspiration plus local administration of low-dose MTX should be recommended as a safe and effective treatment of caesarean scar pregnancy.

ABSTRACT: To investigate psychological distress, serum levels of monoamine neurotransmitters and their metabolites, as well as their correlation with polycystic ovarian syndrome (PCOS).
Thirty infertility patients with PCOS were assigned as the experimental group and 30 infertility patients without PCOS were assigned as the control group. Psychological distress was self-evaluated in all patients with Symptom Checklist 90 (SCL-90). Serum concentrations of norepinephrine (NE) and its metabolite 3-methoxy-4-hydroxyphenylglycol (MHPG), 5-hydroxytryptamine (5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA) and its metabolites homovanillic acid (HVA) and dihydroxy-phenyl acetic acid (DOPAC) were measured by high-performance liquid chromatography.
The anxious and depressive subscales of SCL-90 were significantly higher in infertility patients with PCOS than those without PCOS (p < 0.05). The serum concentrations of 5-HT, 5-HIAA and HVA were significantly lower in infertility patients with PCOS than those without PCOS (p < 0.05). Importantly, the phobia subscale scores of SCL-90 positively correlated with serum MHPG level (p < 0.05), while the hostility subscale's scores negatively correlated with serum DOPAC level (p < 0.05).
Psychological and neurological factors play a crucial role in PCOS.

ABSTRACT: Alcohol induces hyperprolactinemia in both alcoholic men and women, but the mechanism is not fully established. The aim is to investigate the mechanism involved in elevation of serum prolactin level after chronic alcohol administration.
In this study, healthy female SD rats were given alcohol for 8 weeks and checked for serum prolactin level by radioimmunoassay. Interior pituitary cell proliferation was determined by immunohistochemistry score of Ki-67, and hypothalamic neurotransmitters were detected by Coulomb HPLC electrochemical array.
We demonstrated that serum prolactin level and wet pituitary weight of alcohol-fed rats were significantly increased. Interior pituitary cell proliferation was significantly enhanced; hypothalamic dopamine, 5-HT and GABA levels were reduced while glutamate level was increased by chronic alcohol administration; hypothalamic noradrenalin level remained unchanged.
Our study suggested that chronic alcohol administration resulted in elevated serum prolactin level in normal SD rats probably through enhancing pituitary gland cell proliferation combined with altered hypothalamic neurotransmitters that regulate prolactin level.
