Clinical study on electroacupuncture for obese patients with binge eating disorder: A retrospective study.

Binge eating disorder (BED) is a common dietary disorder among obese people. Obesity and eating disorders are related to mental health and physical health. At present, there is no definite and effective method for treatment in clinic. The curative effect of electroacupuncture on obesity is definite. Although there is no conclusive evidence to support its long-term benefits, electroacupuncture has been increasingly used in clinic. This retrospective study determined the prognosis and outcome of electro-acupuncture on obese patients with BED.One hundred forty-three patients with BED and obesity were found from 658 people who participated in the scientific experiment of obesity treatment in Nanjing Hospital of Traditional Chinese Medicine and Nanjing Brain Hospital from March 2015 to June 2018, and 84 patients (aged 18-40 years old) with valid data and uninterrupted treatment were found to be eligible for this retrospective study. According to the intervention methods, the patients were divided into electro-acupuncture combined with cognitive group (n = 32), cognitive therapy group (n = 28), and control group (n = 24). In this study, the 5th edition of Diagnosis and Statistics Manual of Mental Diseases, fasting blood glucose, fasting insulin, total cholesterol (TC), triglyceride, high-density lipoprotein, low-density lipoprotein, body fat rate, muscle mass, visceral index grade, nutrient intake (energy, protein, fat, carbohydrate), body weight, and weight changes before and after treatment were observed.Compared with the cognitive therapy group, negative emotion score, TC, triglyceride, high-density lipoprotein, waist circumference, BW, BMI, body fat percentage of the electroacupuncture combined with cognitive group were lower, while positive emotional scores were higher, and there were significant differences in negative emotional scores, TC, waist circumference and BMI (P < .05). The dietary energy and three major nutrients in the electroacupuncture combined with cognitive group were lower than those in the cognitive group and the blank group (P < .05).The current results suggest that electroacupuncture combined with cognitive therapy is more effective than cognitive therapy alone in treating obese patients with BED. Future prospective studies are necessary to further study the mechanism of electroacupuncture on the obese with BED.

Immunomodulatory Effects of Enzymatic-Synthesized α-Galactooligosaccharides and Evaluation of the Structure-Activity Relationship.

In this study, α-galactooligosaccharides (α-GOSs) were synthesized using galactose as the substrate and α-galactosidase from Aspergillus niger as the catalyst. In the reaction, synthesized products of U1, U2, U3, and U4 were detected by high-performance liquid chromatography. By mass spectrometry, nuclear magnetic resonance, and 1-phenyl-3-methyl-5-pyrazolone derivatization, U1 was the mixture of disaccharides of α-d-Gal p-(1→1)-α-d-Gal, α-d-Gal p-(1→2)-α-d-Gal, α-d-Gal p-(1→3)-α-d-Gal, α-d-Gal p-(1→4)-α-d-Gal, U2 was identified to be α-d-Gal p-(1→6)-α-d-Gal, U3 was the mixture of galactotrisaccharides linked by one α-(1→6)-glycosidic linkage and one other α-glycosidic linkage, and U4 was identified as α-d-Gal p-(1→6)-α-d-Gal p-(1→6)-α-d-Gal. Afterward, the synthesized α-GOSs (U1, U2, U3, U4, and their mixture) as well as α-GOSs (manninotriose, stachyose, ciceritol, and verbascose) obtained from natural materials were used as subjects to evaluate their immunomodulatory effects in vitro by culturing mouse macrophage RAW264.7 cells. The results showed that α-GOS with a higher degree of polymerization had better immunomodulatory activity, while to a certain extent, α-GOS linked with α-(1→6)-galactosidic linkage showed a better immunomodulatory effect.

Effects of α-Galactooligosaccharides from Chickpeas on High-Fat-Diet-Induced Metabolic Syndrome in Mice.

The gut microbiota has the ability to modulate host energy homeostasis, which may regulate metabolic disorders. Functional oligosaccharide may positively regulate the intestinal microbiota. Therefore, effects of α-galactooligosaccharides (α-GOS) from chickpea on high-fat-diet (HFD)-induced metabolic syndrome and gut bacterial dysbiosis were investigated. After 6 weeks of intervention, HFD led to significant increases in levels of blood glucose, total cholesterol, triglyceride, glycated serum protein, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol of mice compared to normal-chow-fed mice. Meanwhile, all of the α-GOS-treated groups significantly decreased above parameters compared to the HFD group. HFD could significantly decrease the content of all bacteria, especially Bacteroides (9.82 ± 0.09 versus 10.3 ± 0.10; p < 0.05) and Lactobacillus (6.67 ± 0.18 versus 7.30 ± 0.24; p < 0.05), and a decrease in the production of short-chain fatty acids was also observed. Treatment with α-GOS significantly increased the number of Bifidobacterium (6.07 ± 0.23 of the low-dose treatment versus 5.65 ± 0.20 of the HFD group) and Lactobacillus (7.22 ± 0.16 of the low-dose treatment). It also significantly promoted the secretion of propionic and butyric acids. These results indicate that α-GOS from chickpeas may affect the metabolic disorders and gut bacterial ecosystem in a positive way.
