Acupuncture Point Injection of Vitamin K1 to Treat Severe Primary Dysmenorrhea: Case Series at a Women’s Health Service in Bologna

Introduction and Aim: Vitamin K acupuncture point injection is an effective and safe menstrual pain treatment derived from Traditional Chinese Medicine, commonly used in some Chinese hospitals. This case series investigated the effectiveness and safety of vitamin K acupuncture point injection on menstrual pain in patients with severe primary dysmenorrhea at a regional public health clinic at Bologna, Italy. Methods: From September 2006 to July 2010, 24 women were enrolled and treated during their first day of menstrual pain with an injection of 1 ml of solution containing 5 mg of vitamin K1 in an acupuncture point San Yin Jiao/Spleen 6 (SP6) bilaterally on the inside of each lower leg above the ankle. Results: Treatment was well tolerated and no major adverse events were reported. Pain relief was observed starting from 2 minutes after treatment and within 30 minutes. All treated women but one (96%) reported a substantial pain reduction (p 0.001). During the six post-treatment follow-up cycles, a trend toward a reduction of menstrual distress evaluated by the Cox Pain Intensity and Duration Scales was documented. Women reported fewer daily life restrictions and consumption of fewer analgesic tablets when compared to what they reported at the pre-treatment cycle. Conclusions: The results of this case series indicate that in primary dysmenorrhea a single vitamin K1 injection in the SP6 acupuncture point has an immediate pain-relieving effect and may ameliorate menstrual pain intensity and duration in post-treatment follow-up cycles.

Serum Metabolomic Characteristics of Primary Dysmenorrhea Rat Model Induced by Estradiol Benzoate Combined with Oxytocin

[Objectives]To investigate the serum metabolomic characteristics of primary dysmenorrhea rat model induced by estradiol benzoate combined with oxytocin,and to reveal its material basis.[Methods]20 female SD rats were randomly divided into control group and model group.The primary dysmenorrhea rat model was established by subcutaneous injection of estradiol benzoate for 10 consecutive days and intraperitoneal injection of oxytocin on the last day.The serum samples of rats in control group and model group were collected by ultra-performance liquid chromatography(UPLC)quadrupole time-of-flight mass spectrometry(Q-TOF-MS).The differential metabolites were identified by multivariable pattern recognition method and endogenous metabolite database,and the metabolic pathways were enriched by Metaboanalyst 5.0 platform.[Results]There were significant differences in serum metabolic profiles between the two groups.A total of 36 potential biomarkers of primary dysmenorrhea including L-tyrosine,glycocholic acid,citric acid,palmitoyl carnitine and cholesterol were screened and identified,mainly involving metabolic pathways such as phenylalanine,tyrosine and tryptophan biosynthesis,glycerophospholipid metabolism,and primary bile acid biosynthesis.[Conclusions]The serum metabolic profile of primary dysmenorrhea rats deviates significantly from that of healthy rats,and there are multiple metabolic pathway disorders,which are mainly related to phenylalanine,tyrosine and tryptophan biosynthesis,glycerophospholipid metabolism,and primary bile acid biosynthesis.

Analgesic effects and hemodynamic mechanisms of perpendicular and transverse needling at Sanyinjiao(SP 6) in patients with primary dysmenorrhea: A randomized controlled trial

Objective: To explore the analgesic effects and uterine hemodynamics of perpendicular needling(PN)and transverse needling(TN) at SP 6 in patients with primary dysmenorrhea(PD).Methods: In this randomized controlled trial, patients with PD diagnosed with cold-dampness congealing pattern were randomly assigned in a ratio of 1:1 to receive PN or TN at bilateral SP 6 for 10 min.Acupuncture was performed when the menstrual pain score was over 40 mm on the first day of menstruation, as measured using the visual analog scale for pain(VAS-P). The primary outcome was average menstrual pain(VAS-P). Secondary outcomes included the pulsatility index(PI), resistance index(RI), and systolic-diastolic peaks ratio(S/D) in uterine arteries as measured using color Doppler ultrasonography;anxiety as assessed using the Hamilton Anxiety Rating Scale(HAMA), blood pressure(BP),and heart rate(HR).Results: Forty-eight patients completed the study. The TN group exhibited a significant reduction in VAS-P scores(-5.71 mm, 95% confidence interval(CI): -8.78, -2.63, P =.001), RI values(-0.05, 95% CI:-0.09, -0.01, P=.015), and HAMA values(-2.50, 95% CI: -4.78, -0.22, P=.032) when compared with the PN group. No significant differences in PI, S/D, BP, or HR values were observed between the two groups(P >.05).Conclusion: TN at SP 6 was superior to PN in alleviating menstrual pain and anxiety in patients with PD.This analgesic effect of TN may be due to its better ability to improve uterine arterial blood flow via decreases in RI values.

A Systematic Review and Meta-Analysis of Herb-Partitioned Moxibustion in the Treatment of Primary Dysmenorrhea

OBJECTIVE: To systematically evaluate the clinical effects of herb-partitioned moxibustion on patients with primary dysmenorrhea. METHODS: Randomized controlled trials of herb-partitioned moxibustion for primary dysmenorrhea published from the year the database was established to November, 2017 were searched from CNKI,Wanfang Database, VIP database, CBM, PubMed, Embase, and Cochrane Library. Data extraction and quality evaluation were performed in papers meeting inclusion criteria. The outcomes measurements included clinical effect rate, visual analogue score(VAS), plasma PGF2α, adverse events, recurrence rate, and quality of life. The Rev Man 5.3 software was applied for meta-analysis. RESULTS:(1) A total of 16 studies were eligible and included in the meta-analysis involved1126 patients.(2) A statistically significant increasing in clinical effective rate was found in HMP group compared with control group [OR=3.49, 95%CI(2.25, 5.39), P<0.00001].(3) There was significant difference between two groups in visual analogue score [MD=–7.48, 95%CI(–9.93, –5.02), P<0.00001], which suggested the patients who received HPM had lower VAS scales than those who received no HPM.(4) There was significantly difference in serum PGF2α between the groups receiving HPM and the control group [MD=–4.61, 95%CI(–9.19, –0.03), P=0.05].(5) 2 trials reported followup duration, and all included studies did not mention the recurrence of PD during the follow-up stage, and all included studies did not mention the improvement of quality of life of PD during period of management and follow-up stage.CONCLUSIONS: Herb-partitioned moxibustion is beneficial for primary dysmenorrhea. However, the conclusion is not completely accurate with limitations of the current RCTs. The safety of herb-partitioned moxibustion remains to be defined by future studies. Attention should be paid to long-term effects of herb-partitioned moxibustion in clinical research. High-quality RCTs are required to confirm the effectiveness of herb-partitioned moxibustion for primary dysmenorrhea.
