Immediate Effect of Acupuncture at Sanyinjiao (SP6) and Xuanzhong (GB39) on Uterine Arterial Blood Flow in Primary Dysmenorrhea

OBJECTIVEnThe objective of this study was to compare immediate effect of acupuncture at SP6 on uterine arterial blood flow in primary dysmenorrhea with that of GB39.nnnDESIGNnThis was a prospective, randomized clinical trial.nnnSETTINGnSixty-six (66) patients with primary dysmenorrhea from the Affiliated Hospital of Shangdong University of Traditional Chinese Medicine were recruited.nnnINTERVENTIONSnThe SP6 group (n =32) was treated with manual acupuncture at bilateral SP6 for 5 minutes after obtaining needling sensation (de qi) during the period of menstrual pain, whereas the control group (n = 34) was needled at GB39 of both sides for 5 minutes when they suffered menstrual pain.nnnMAIN OUTCOME MEASURESnDifferences in pulsatility index (PI), resistance index (RI), and ratio of systolic peak and diastolic peak (A/B) in uterine arteries were the main outcome measures.nnnRESULTSnHighly significant reductions were observed in the SP6 treatment group 5 minutes after treatment in menstrual pain scores (8.17 ± 1.90 versus 11.20 ± 2.66; p < 0.001), values of PI (1.75 ± 0.48 versus 2.32 ± 0.70; p < 0.001), RI (0.72 ± 0.11 versus 0.78 ± 0.07; p < 0.001), and A/B (4.33 ± 1.37 versus 5.23 ± 1.67; p < 0.001). Compared with the GB39 control group, patients in the SP6 treatment group showed significant reductions in 5 minutes after treatment in the changes of menstrual pain scores (3.03 ± 2.36 versus 0.00 ± 0.29; p < 0.001), values of PI (0.57 ± 0.42 versus -0.10 ± 0.58; p < 0.001), RI (0.06 ± 0.08 versus -0.03 ± 0.15; p < 0.01), and A/B (0.90 ± 0.87 versus 0.23 ± 1.02; p < 0.01). There were no significant changes in menstrual pain scores, values of PI, RI, or A/B before and after treatment in the GB39 control group (p > 0.05). No adverse events from treatment were reported.nnnCONCLUSIONSnThis study suggests that needling at SP6 can immediately improve uterine arterial blood flow of patients with primary dysmenorrhea, while GB39 does not have these effects.

A clinical trial of acupuncture about time-varying treatment and points selection in primary dysmenorrhea

OBJECTIVEnTo observe the clinical therapeutic effects of acupuncture at single point Shiqizhui (EX-B8) and multi-points in time-varying treatment for primary dysmenorrhea.nnnMETHODSn600 patients with primary dysmenorrhea were randomly assigned to the single point group (n=200) including group A (treating before the menstruation, n=100) and group B (immediately treating as soon as pain occurrence, n=100), the multi-points group (n=200) including group C (treating before the menstruation, n=100) and group D (immediately treating as soon as pain occurrence, n=100), or the control group, group E (n=200, no treatment). The therapeutic effects were analyzed after treatment for three menstrual cycles and interviewed for three follow-up periods.nnnRESULTSnAcupuncture could effectively relieve menstrual pain for primary dysmenorrhea compared with the control group (P<0.05, P<0.01). Immediate pain relief occurred following acupuncture within 5 min in group B (P<0.01) and group D (P<0.01), and the two groups obviously relieved menstrual pain for VAS scores. Both group A and group C obviously relieved menstrual pain (P<0.01), and group C was better than group A (P<0.05). Compared with group D, Group C was much better for CMSS scores in cycle 1.nnnCONCLUSIONnTreating before the menstruation is better than immediately treating as soon as pain occurrence at the improvement in symptoms of dysmenorrheal at multi-points. And single point is better than multi-points when immediately treating as soon as pain occurrence. The present trial suggest Shiqizhui (EX-B8) should be chosen as a convenient point.

Randomized Clinical Trial: The Clinical Effects of Herb-Partitioned Moxibustion in Patients with Diarrhoea-Predominant Irritable Bowel Syndrome

Objective. To explore the efficacy of Herb-partitioned moxibustion in treating IBS-D patients. Method. 210 IBS-D patients were randomly assigned on a 3 : 3 : 2 basis to group HM, group FM, or group PB for 4-week treatment. The change of GSRS total score at weeks 4 and 8, the changes of GSRS specific scores, and adverse events were evaluated. Results. Patients in group HM and group FM had lower GSRS total score at week 4 (1.98 ± 0.303, 2.93 ± 0.302 versus 3.73 ± 0.449) and at week 8 (2.75 ± 0.306, 3.56 ± 0.329 versus 4.39 ± 2.48) as compared with patients score in group PB. However, there was no significant difference of GSRS total score between group HM and group FM. The effect of HM was significantly greater than that of orally taking PB in ameliorating the symptoms of rugitus (0.38 versus 0.59, P < 0.05), abdominal pain (0.28 versus 0.57, P < 0.01), abdominal distension (0.4 versus 0.7, P < 0.01), and increased passage of stools (0.06 versus 0.25, P < 0.01) at the end of treatment period. In the follow-up period, patients therapeutic effect in group HM remained greater than that in group FM (in abdominal pain, abdominal distension, and increased passage of stools) and that in group PB (in loose stools). Conclusions. HM appears to be a promising, efficacious, and well-tolerated treatment for patients with IBS-D.

Research of Herb-Partitioned Moxibustion for Primary Dysmenorrhea Patients Based on the LC-MS Metabonomics

Objective. To explore the efficacy and mechanism of primary dysmenorrhea patients were treated with herb-partitioned moxibustion through metabonomics. Methods. 20 patients with primary dysmenorrhea were randomized into two groups, separately treated with herb-partitioned moxibustion at CV8 (shenque) and acupuncture at SP6 (sanyinjiao). After three menstrual cycles treatment, the intensity of menstrual pain using VAS and the changes of metabolites of plasma using LC-MS were observed. Results. The VAS of two groups decreased with different descending range. Herb-partitioned moxibustion upregulated 20α-dihydroprogesterone, pregnenolone, prostaglandin E2 and γ-aminobutyric acid and downregulated the content of estrone and prostaglandin H2, while acupuncture upregulated pregnenolone and 20α-dihydroprogesterone and downregulated 2-methoxyestradiol-3-methylether, 15-hydroxyeicosatrienoic acid and 6-keto-prostaglandin. Discussion. It was effective in relieving the abdominal pain by these two therapies. Herb-partitioned moxibustion is superior to acupuncture for primary dysmenorrhea, which could be related to regulating the endocrine hormone.
