Hyperandrogenism is a core factor in the series of reproductive and endocrine metabolic disorders involved in polycystic ovary syndrome (PCOS). Abnormalities in enzymatic activity and the expression of ovarian granular cell layer P450arom and theca cell P450c17α can lead to an atypical environment of local ovarian hormones, including excessive androgen levels. Rat models prepared with letrozole exhibit similar endocrine and histological changes to those that occur in human PCOS. We used such a model to study the role of electro-acupuncture (EA) in regulating ovarian P450arom and P450c17α enzymatic activity and mRNA expression in PCOS rats. Female Sprague Dawley (SD) rats aged 42 days were randomly divided into 3 groups (control, PCOS, and PCOS EA) consisting of 10 rats each. The PCOS and PCOS EA groups were administered a gavage of 1.0 mg/kg-1 of letrozole solution once daily for 21 consecutive days. Beginning in the ninth week, the PCOS EA group was administered low-frequency EA treatment daily for 14 consecutive days. After the treatment, we obtained the following results. The estrous cycles were restored in 8 of the 10 rats in the PCOS EA group, and their ovarian morphologies and ultrastructures normalized. The peripheral blood measurements (with ELISA) showed significantly decreased androgens (i.e., androstenedione and testosterone) with significantly increased estrogens (i.e., estrone, estradiol) and increased P450arom with decreased P450C17α. Immunohistochemistry and Western blotting methods showed enhanced expression of ovarian granular cell layer P450arom as well as decreased expression of theca cell layer P450C17α. Fluorescence quantitative PCR methods showed enhanced expression of ovarian granular cell layer P450arom mRNA as well as decreased expression of theca cell layer P450C17α mRNA. These results may help explain the effects of electro-acupuncture in changing the local ovarian hyperandrogenic environment and improving reproductive and endocrine metabolic disorders in PCOS. © 2013 Sun et al.

In contrast to the reductionist approach of Western medicine that is based on modern anatomy, cell and molecular biology, Traditional Chinese Medicine (TCM) uses a unique theory system and an individualised and holistic approach to describe health and disease, based on the philosophy of Yin-Yang balance and an emphasis on harmony of functions. These two medicine systems disagree with each other in many situations as both of them may observe health from their limited perspective. GP-TCM aims to inform best practice and harmonise research of the safety and efficacy of TCM, especially Chinese herbal medicines (CHM) and acupuncture, in EU Member States using a functional genomics approach through exchange of opinions, experience and expertise among scientists in EU Member States and China. In 10 proposed work packages, we will take actions to review the current status, identify problems and solutions in the quality control, extraction and analysis of CHM. While these fundamental issues are addressed, discussion forums emphasising the use of functional genomics methodology in research of the safety, efficacy and mechanisms of CHM and acupuncture will be the core of this Coordination project. It will include the application of the technique in cell-based models, animal models and in clinical studies. Guidelines about good practice and agreed protocols in related research areas will be published to promote future TCM research in all the EU member states; online tools and research resources will be made available to EU member states; EU member states and additional China partners will be invited to join this network; The GP-TCM Research Association will be established during this project and kept running autonomously to continue the guidance and coordination of EU-China collaboration in TCM research.

OBJECTIVE: To explore the effect of electroacupuncture and Chinese kidney-nourishing medicine on insulin (INS), adiponectin (APN), leptin (LEP), and glucolipid metabolism of obese patients with polycystic ovary syndrome (PCOS). METHODS: Sixty-seven obese PCOS patients were randomly divided into two groups. Thirty-three patients in the acupuncture-medicine group were treated three times a week with electroacupuncture at the Tianshu (ST 25), Zhongwan (CV 12), Qihai (CV 6), Sanyinjiao (SP 6), Geshu (BL 17), and Ciliao (BL 32) acupoints. They also took the Chinese drug, Tiankui capsule, for 3 months as a course of treatment. Point-taking and treatment in the electroacupuncture group of 34 patients was the same as those in the acupuncture-medicine group. We observed and compared the changes in the obesity-related indexes of body weight (BW), body mass index (BMI), and waist-hip ratio (WHR), as well as fasting plasma glucose (FPG), fasting insulin (FINS), APN, and LEP. RESULTS: BW, BMI, WHR, and FINS decreased and insulin sensitivity index (ISI) and APN were higher in the acupuncture-medicine group than in the electroacupuncture group (P<0.01). There was no obvious difference in LEP between the two groups (P>0.05). CONCLUSION: Acupuncture combined with medicine is better than just electroacupuncture for obese PCOS patients by improving obesity-related indexes, insulin sensitivity, and APN level. This indicates that acupuncture-medicine therapy is worth clinical popularization. © 2013 JTCM. All rights reserved.
