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.

CONTROL OBSERVATION OF THERAPEUTIC EFFECTS ON SYNDROME OF THE 3^(rd) LUMBAR TRANSVERSE PROCESS WITH THICK SILVER WARMING NEEDLING AND ELECTRIC ACUPUNCTURE

Objective: To compare the clinical therapeutic effects on the syndrome of L3 transverse process between thick silver warming needling and electric acupuncture. Methods: One hundred and twenty cases of the syndrome of L3 transverse process were randomized into observation group and the control, 60 cases for each one. Thick silver warming needling was applied in observation group and electric acupuncture in the control. Results: The curative rate was 81.7% in observation group and 58.3% in the control, indicating significant difference （P<0.01）. The significant difference in the therapeutic effects between two groups had not been discovered yet for the cases within 3 months of sickness （P>0.05）, but, the therapeutic effect in observation group was superior to that in the control for the cases over 3 months of sickness （P<0.01）. Conclusion: The therapeutic effects of thick silver warming needling and electric acupuncture were quite advantageous on the syndrome of L3 transverse process, but that of thick silver warming needling was superior to electric acupuncture.

Creation of Super Long Transversely Polarized Optical Needle Using Azimuthally Polarized Multi Gaussian Beam

The intensity distribution in the focal region of a high-NA lens for the incident azimuthally polarized multi Gaussian beam transmitted through a multi belt spiral phase hologram is studied on the basis of the vector diffraction theory. Here we report a new method used to generate a needle of transversely polarized light beam with sub diffraction beam size of 0.366A that propagates without divergence over a long distance of about 22A in free space. We also expect that such a light needle of transversely polarized beam may find its applications in utilizing optical materials or instruments responsive to the transversal field only.

Transverse striation needling for 30 cases of cervical spondylosis

Objective To observe the clinical efficacy of transverse striation needling in treatment of cervical spondylosis.Method Thirty patients were diagnosed with cervical spondylosis in Guoyitang Clinic,Yanwu Branch of Zhongshan Hospital,Xiamen University from July,2013 to March,2015,and were included into this study.Transverse striation needling,i.e.transverse insertion into the transverse striation of the cervical vertebra,was adopted for the 30 patients,and conventional acupuncture at Fēngchí（风池 GB 20,bilateral）,Jiānj？ng（肩井 GB 21,bilateral） and Jiānzhōngshù（肩中俞 SI 15,bilateral） was combined.The treatment was conducted for once a day,twice a week,and 6 times were needed in total.Follow-up visit was performed two months after the treatment.Result Among the 30 patients,the markedly effective rate was 70.0%（21/30）,effective rate was 30.0%（9/30）,and the total effective rate was 100.0%.There was no relapse during two months after the treatment.Conclusion The therapeutic effect of transverse striation needling in treatment of cervical spondylosis was good.
