[Effect of acupuncture on migraine without aura: a resting-state functional magnetic resonance study].

Objective: To observe therapeutic effect of acupuncture on migraine without aura and the changes of brain functional connectivity (FC) using resting-state functional magnetic resonance imaging (rs-fMRI).

Methods: Thirty-four patients with migraine without aura were included into an observation group and treated with acupuncture at Baihui (GV 20), Xuanlu (GB 5), Shuaigu (GB 8), Taiyang (EX-HN 5), etc. Using G6805-Ⅱ electric acupuncture apparatus, the ipsilateral Fengchi (GB 20) and Shuaigu (GB 8) were connected and stimulated with continuous wave, 2 Hz in frequency and 0.

[Rolling needle pricking-cupping therapy and traditional pricking-cupping therapy for cervical spondylosis of neck type: a randomized controlled trial].

Objective: To compare the clinical efficacy between rolling needle pricking-cupping (RNP-C) and traditional pricking-cupping (TP-C) for cervical spondylosis of neck type.

Methods: A total of 96 patients with cervical spondylosis of neck type were randomly divided into an RNP-C group, a TP-C group and an electroacupuncture (EA) group, 32 cases in each group. Each group was treated with EA at Jingbailao (EX-HN 15), Fengchi (GB 20), Dazhui (GV 14), Jianjing (GB 21) and points with continuous wave and 2 Hz of frequency; each EA treatment lasted for 20 min, once every 3 to 5 days, totaling 6 treatments.

Laser-induced interstitial thermotherapy via a single-needle delivery system: Optimal conditions of ablation, pathological and ultrasonic changes.

This study aimed to examine the optimal conditions of laser-induced interstitial thermotherapy (LITT) via a single-needle delivery system, and the ablation-related pathological and ultrasonic changes. Ultrasound (US)-guided LITT (EchoLaser system) was performed at the output power of 2-4 Wattage (W) for 1-10 min in ex vivo bovine liver. Based on the results of the ex vivo study, the output power of 3 and 4 W with different durations was applied to in vivo rabbit livers (n=24), and VX2 tumors implanted in the hind limbs of rabbits (n=24).

Toward High Performance n-Type Thermoelectric Materials by Rational Modification of BDPPV Backbones.

Three n-type polymers BDPPV, ClBDPPV, and FBDPPV which exhibit outstanding electrical conductivities when mixed with an n-type dopant, N-DMBI ((4-(1,3-dimethyl-2,3-dihydro-1H-benzoimidazol-2-yl)phenyl)dimethylamine), in solution. High electron mobility and an efficient doping process endow FBDPPV with the highest electrical conductivities of 14 S cm(-1) and power factors up to 28 μW m(-1) K(-2), which is the highest thermoelectric (TE) power factor that has been reported for solution processable n-type conjugated polymers. Our investigations reveal that introduction of halogen atoms to the polymer backbones has a dramatic influence on not only the electron mobilities but also the doping levels, both of which are critical to the electrical conductivities.
