Background: Migraine, a common neurological disorder, increases the risk of psychiatric disorders. Currently, the efficacy of conventional therapies is considered unsatisfactory. Acupuncture has been gaining popularity in treatment of neuropsychiatric disease. This study aimed to investigate the effect of acupuncture on medical expenditure and the risk of depression and anxiety in migraine patients. Methods: Patients with migraine were either selected for acupuncture treatment or no treatment based on the 1:1 propensity score-matched method from the Taiwanese National Health Insurance Research Database between 2000 and 2012 and followed up until the end of 2013. The observed outcome measures were comparison of medical expenditure and incidence of depression/anxiety in the two cohorts. Results: The acupuncture cohort had a lower medical expenditure within 1 year of the intervention than the non-acupuncture cohort (p < 0.001). The acupuncture cohort had a reduced risk of depression [adjusted hazard ratio [HR], 0.61, 95% confidence interval [CI], 0.39-0.95] and anxiety (adjusted HR, 0.51, 95% CI, 0.43-0.59) after adjusting for sex, age, monthly income, urbanization level, occupation category, baseline comorbidities, and medicines used. The Kaplan-Meier analysis revealed that the cumulative incidence of depression and anxiety was significantly lower in the acupuncture cohort than in the non-acupuncture cohort during the 13-year follow-up period (log-rank test, p < 0.001). Conclusions: Acupuncture could reduce medical expenditure and the risk of depression and anxiety during the long-term follow-up period in migraine patients. However, the regulatory effects and mechanisms should be assessed in further clinical research.
Vanillin is a natural dietary flavoring widely used in the food industry. Colorectal cancer (CRC) is one of the common malignancies in the world. Chronic intestinal inflammation is a risk factor for the development of CRC. We have previously found that vanillin improves and prevents colitis in mice. Here we evaluated the inhibitory activities of vanillin on a mouse model of colitis-induced CRC. Mice were challenged intraperitoneally with azoxymethane (AOM) and orally with dextran sodium sulfate (DSS). Various dosages of vanillin were orally administered for 13 consecutive weeks. Vanillin alleviated the development of tumors in AOM/DSS-induced mice. The total number of tumors in 100 mg/kg vanillin group was significantly reduced by 57.14 ± 7.67%, compared with sham group. Gene expression analysis showed that vanillin downregulated the expression levels of proteasome genes in colon tissues. Moreover, vanillin at 10 mM significantly suppressed proteasome activities in HCT-116 cells by 41.27 ± 0.41%. Furthermore, vanillin diminished the phosphorylation of mitogen-activated protein kinases (MAPKs) and reduced the number of p65-positive cells, proliferating cells, and granulocytes in colon tissues with statistical significance. In conclusion, our data suggested that vanillin was a bioactive compound that ameliorated the development of AOM/DSS-induced colon cancer in mice. Moreover, the amelioration of vanillin might be associated with the downregulation of proteasome, nuclear factor-κB, and MAPK pathways.
