title: [Improvement of the oocyte quality with electroacupuncture in infertility patients of kidney deficiency pattern].
abstract: OBJECTIVE
  To explore the impact and effect mechanism of electroacupuncture (EA) on oocyte quali ty in the patients with infertility of kidney deficiency pattern.
  
  
  METHODS
  Sixty-six cases differentiated as kidney de ficiency and with in vitro fertilization-embryo transplantation (IVF-ET), aged fromnt 35 to 42 years were rando- mized into an observation group and a control group, 33 cases in each one. The IVF-ET therapy of the long proto- col with gonadotrophin releasing hormone agonist was adopted in the two groups. In the observation group. on the 5th day of menstruation in IVF cycle, EA was applied to Sanyinjiao (SP 6). Zigong (EX CA 1), Zhongji (CV 3) and Guanyuan (CV 4). In the control group, the sham-acupuncture was applied to the same acupoints. The treatment was given once every two days till the date of egg collection and the needles were retained for 30 min each time. The change in the score of kidney deficiency syndrome, the high-quality oocyte rate, the high-quality embryo rate and clinical pregnant rate were observed in the two groups. The levels of insulin-like growth factor-i (IGF-1) and IGF-2 in follicular fluid and the serum β-endorphin β-EP) on the date of egg collection and the correlation with oocyte quality were compared bIetween the two groups.
  
  
  RESULTS
  1) In the observation group, the kidney deficiency syndrome score after treatment was reduced apparently as compared with that before treatment (P<0. 05), the score after treatment in the observation group was reduced much more apparently as compared with the control group (P<0.05). 2) The high-quality egg rate and the high-quality embryo rate in the observation group were both higher than those in the control group [81.3% (161/198) vs 57.6% (98/170), 59.8% (58/97) vs 37.7% (26/69), both P<0.05]. 3) Compared with the control group. the levels of IGF-1 and IGF-2 in follicular fluid and serum β-EP on the day of egg collection were all increased obviously in the observation group (all P<0. 05). 4) The levels of IGF-1 and IGF-2 in follicular fluid and serum β-EP presented the linear positive correlation with the high-quality egg rate.
  
  
  CONCLUSIONS
  EA effectively improves the expressions of IGF in follicular fluid and serum β-EP, increases the high-quality egg rate and high-quality embryo rate and relieves the symptoms of kidney deficiency.
