Abstract
There is currently no convincing evidence that acupuncture has any specific effects on autonomic nervous function as assessed by heart rate variability (HRV). We examined whether the stimulation of neighboring acupunctural points, Danzhong (CV17) and Zhongting (CV16) on the anterior median line of the thorax, induced different effects on HRV.

In 14 healthy males, epifascial acupunctural stimulation (single instantaneous needle stimulation on the fascial surface without producing De-Qi sensation) was performed at CV17 and CV16 on different days in a clinical study utilizing a cross-over design.

We found that the stimulation of CV17, but not of CV16, decreased the heart rate (P=0.01, repeated measures ANOVA) and increased the power of the high-frequency component of the HRV, an index of cardiac vagal activity (P=0.01).

The low-frequency to high-frequency ratio, an index of sympathetic activity showed no significant changes for either point. Our observations could not be explained as either nonspecific or psychological/placebo effects of needle stimulation.

This study provides strong evidence for the presence of a specific acupunctural point that causes the modulation of cardiac autonomic function.

Abstract:

OBJECTIVE AND METHODS:
The crucial symptom of atopic eczema is itch. Acupuncture has been shown to exhibit a significant effect on experimental itch; however, studies focusing on clinical itch in atopic eczema and corresponding mechanisms are lacking. The study design was a unicenter, single-blinded (observer), prospective, randomized clinical pilot trial with an additional experimental part. In 10 patients with atopic eczema, we investigated the effect of acupuncture treatment (n = 5) compared to no treatment (n = 5) on itch intensity and in vitro basophil CD63 expression upon allergen stimulation (house dust mite and timothy grass pollen) in a pilot trial.


RESULTS:
Mean itch intensity in a visual analog scale was rated significantly lower in the acupuncture group (-25% ± 26% [day 15-day 0]; -24% ± 31% [day 33-day 0]) than in the control group (15% ± 6% [day 15-day 0]; 29% ± 9% [day 33-day 0]). From day 0 (before treatment) to day 15 (after 5 acupuncture treatments) as well as day 33 (after 10 acupuncture treatments), the acupuncture group showed less CD63 positive basophils than the control group regarding stimulation with house dust mite and grass pollen allergen at various concentrations (5 ng/mL, 1 ng/mL, 0.5 ng/mL, or 0.25 ng/mL).

CONCLUSIONS:

Our results show a reduction of itch intensity and of in vitro allergen-induced basophil activation in patients with atopic eczema after acupuncture treatment. Reducing basophil activation can be a further tool in investigating the mechanisms of action of acupuncture in immunoglobulin E-mediated allergy. Due to the limited number of patients included in our pilot trial, further studies are needed to strengthen the hypothesis.

Gastrointestinal symptoms of infantile colic and their change after light needling of acupuncture: a case series study of 913 infants.

Date: 2011 Aug 11

Journal: Chin Med 6(1):28.

ABSTRACT:

Background Infantile colic is a common painful clinical condition associated with signs of distended intestines and an increase in colon peristalsis. However, clinical documentation of observed gastrointestinal functions in the condition is still lacking. Even though the ailment is common, no clear treatment guidelines exist.

While acupuncture with minimal stimulation has been shown to be effective in reducing crying behaviour of infants suffering from colic, the documented effect of acupuncture on gastrointestinal function in children with infantile colic is scarce.

This case series study aims to document the symptoms of routinely rated gastrointestinal function and the changes in these symptoms after minimal acupuncture in a larger group of children with infantile colic.


Methods:

This study included 913 infants with normal weights, and lengths at birth. The infants' mean age was 5.4 weeks when the observations started, and had colic symptoms since two weeks after birth. Light needling stimulation of the acupuncture point LI4 was performed for 10-20 seconds bilaterally on a daily basis for a mean of 6.2 consecutive days. A questionnaire with verbal rating scales for the parents' evaluation was used before and after the treatment period.

Results Before treatment the infants were assessed by the parents in terms of 'often have inflated stomachs' (99%) and 'seldom drool' (76%), 'regurgitate' (53%) and 'belch' (62%). Moreover, the reported frequency of defecation was 5-8 times per day (64%), with a yellowish-green colour (61%) and with a water-thin consistency (74%).

After treatment, the variables of inflated stomachs, drooling and regurgitating were systematically changed, and rated by the parents as occurring 'sometimes' while belching was rated as occurring 'often' and the frequency of defecation was reduced to 1-4 times/day with a mustard yellow colour and a gruel-like consistency. The parents also rated their impression of the infants' general colic symptoms including crying behaviour as much ameliorated in 76% of the cases.


Conclusion:

The results of the present study show that minimal acupuncture at LI4 in infantile colic is an effective and easy treatment procedure that, furthermore, is reported to be without serious side effects.
