A randomized trial of Chinese medicine Lirukang Granule combined with psychological intervention for cyclomastopathy and menoxenia.

OBJECTIVE: To observe the influence of therapy with Chinese medicine Lirukang Granule (, LRKG) combined with psychological intervention on anxiety states and sex hormones in patients with cyclomastopathy and menoxenia. METHODS: A total of 470 subjects were randomly assigned to three groups by the net-central randomization system, the treatment group (161 patients, treated with LRKG and psychological intervention), the Chinese medicine group (157 patients, treated with LRKG), and the psychological intervention group (152 patients, treated with psychological intervention). The dose of LRKG was 12 g three times per day; psychological intervention included establishing relations, cognitive intervention and psychological persuasion, 30-40 min per session, once a week. The therapy duration for all groups was three months. The efficacy was compared and anxiety state/State-Trait Anxiety Invertory (STAI) scoring was measured before and after treatment. The serum estradiol (E2), progesterone (P), prolactin (PRL) and follicle stimulating hormone (FSH) levels of 60 patients selected randomly from each group during the luteal phase were measured before and after treatment, and a group of 20 healthy women were evaluated for comparison. A follow-up was arranged for one year after treatment. RESULTS: Thirty subjects were lost to follow-up. (1) Comparison of efficacy: the markedly effective rate and the total effective rate of the treatment group were 86.67% (131/150) and 98.00% (147/150), respectively; of the Chinese medicine group, 64.58% (93/144) and 90.27% (130/144), respectively; and of the psychological intervention group, 0% (0/146) and 3.42% (5/146), respectively. The markedly effective rate and the total effective rate in the treatment group were significantly higher than those in the Chinese medicine and psychological intervention groups (P < 0.05). (2) Comparison of STAI scoring: STAI scoring was decreased dramatically in the treatment group after treatment compared with that of the Chinese medicine group (P < 0.01), but there was no significant difference compared with the psychological intervention group. (3) Comparison of levels of sex hormones: E2, P, PRL and FSH of the three patient groups were disordered before treatment, and significantly different from healthy women (P < 0.01). After treatment, the levels of P and FSH of the treatment group were significantly increased (P < 0.01), E2 and PRL were significantly reduced, which were also significantly decreased compared with the psychological intervention groups (P < 0.01). (4) FOLLOW-UP: the markedly effective rate and the total effective rate of the treatment group remained higher than those of the other two groups after one year of treatment (P < 0.05). (5) Adverse reactions: no obvious adverse reactions were found among the three groups. CONCLUSIONS: Therapy with Chinese medicine combined with psychological intervention was effective for short-term and long-term treatment of cyclomastopathy and menoxenia. The mechanism might be related to the regulation of sex hormones.
