Effect of Biaoben (标本) Acupoints Combination Needling on Anxiety-like behavior and Gut flora in Model Rats of Irritable Bowel Syndrome with Predominant Diarrhea and Anxiety
To explore the possible mechanism of Biaoben (标本) acupoints combination needling in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D) with anxiety.
Methods
2
Ten rats were randomly selected from 60 SD rats as blank group and the remaining rats were prepared with the IBS-D and anxiety model. The successful modeling rats were randomly divided into model group, routine acupoints needling group and Biaoben acupoints combination needling group, with 10 rats in each group. The model group was left untreated. In the routine acupoints needling group, “Tianshu (ST25)”,“Zusanli (ST36)” and “Shangjuxu (ST37)” were selected, while in the Biaoben acupoints combination needling group,“Neiguan (PC6)”,“Zusanli (ST36)”, and “Guanyuan (CV4)” were used. Both groups received acupuncture for 20 minutes each time, once a day for 14 days. Bristol stool form scale (BSFS) and abdominal withdrawal reflex were assessed. Anxiety was evaluated by sucrose preference test, open field test, and elevated plus maze test. The absolute fluorescence quantitative PCR method was used to detect Escherichia coli, Enterococcus, Bacteroides, Lactobacillus, Bifidobacterium, Peptostreptococcus, and Bacillus contents.
Results
2
Compared to those in the blank group, the model group had higher BSFS score, lower sucrose preference percentage, increased abdominal withdrawal reflex score at the diastolic pressure of 40, 60, and 80 mmHg, decreased visceral pain threshold, reduced distance of locomotion, number of uprights, and dwell time in the central area in the open field test, as well as the dwell time in the open arm, number of times into the open arm, and total distance in the elevated plus maze (
P
<0.05). Compared to those in the model group, the above-mentioned outcomes were significantly improved in both needling groups (
P
<0.05), and more improvements were found in the Biaoben
acupoints combination needling group in terms of the sucrose preference percentage, visceral pain threshold, open field test and elevated plus maze indicators (
P
<0.05). Regarding the gut flora, both needling groups could decrease the content of Escherichia coli, Enterococcus, Bacteroides, and Peptostreptococcus, and increase the content of Lactobacillus, Bifidobacterium, and Bacillus, with more improvements in the Biaoben
acupoints combination needling group (
P
<0.05).
Conclusion
2
The Biaoben acupoints combination needling is effective in improving the stool properties and relieving the anxiety-like negative emotions of IBS-D rats with anxiety, and the mechanism may be related to the regulation of the number of intestinal beneficial and pathogenic bacteria.
