Effects of Tuina Combined With Moxibustion on Breast Cancer-Related Lymphedema: A Randomized Cross-Over Controlled Trial.

The objective of this study is to evaluate the effect of Tuina combined with moxibustion on relieving breast cancer-related lymphedema (BCRL). A randomized cross-over controlled trial was conducted at our institution. All patients with BCRL were assigned to 2 groups: Group A and Group B. In the first period (weeks 1-4), tuina and moxibustion were performed in Group A and pneumatic circulation and compression garment in Group B. The washout period took place from weeks 5 to 6. In the second period (weeks 7-10), pneumatic circulation and compression garment were performed in Group A, and tuina and moxibustion in Group B. Therapeutic efficacy was evaluated by measuring the affected arm volume, circumference, and Visual Analog Scale for swelling. Regarding the results, a total of 40 patients were included, and 5 cases were dropped. After treatment, both the traditional Chinses medicine (TCM) treatment and complete decongestive therapy (CDT) was found to reduce the volume of the affected arm (P < .05). At the endpoint (visit 3), compared with CDT, the effect of the TCM treatment was more evident than that of CDT (P < .05). After the TCM treatment, the arm circumference at the elbow crease and proximal 10 cm to elbow crease was reduced, which was statistically different from that before treatment (P < .05). Post-CDT treatment, the arm circumference at proximal 10 cm to wrist crease and the elbow crease and proximal 10 cm to elbow crease decreased, which was statistically different from that before treatment (P < .05). At the endpoint (visit 3), the arm circumference at proximal 10 cm to elbow crease of the patients treated with TCM was less than that of CDT (P < .05). Moreover, the VAS scores for swelling were better after compared with before TCM treatment and CDT (P < .05). At the endpoint (visit 3), the subjective relief of swelling by TCM treatment was greater than CDT (P < .05). Ultimately, tuina combined with moxibustion can alleviate BCRL symptoms, which is primarily reflected in reducing the affected arm volume and circumference and relieving swelling.Trial registration: Chinese Clinical Trial Registry (Registration Number ChiCTR1800016498).

Comparative evaluation of the antioxidant effects of the natural vitamin C analog 2-O-ß-D-glucopyranosyl-L-ascorbic acid isolated from Goji berry fruit.

2-O-ß-D-Glucopyranosyl-L-ascorbic acid (AA-2ßG) is a natural derivative of vitamin C (Lascorbic acid, AA) isolated from Goji berry (Lycium barbarum L.) fruit. We evaluated the antioxidant activities of AA-2ßG and AA using in vitro and in vivo model systems. In vitro radical scavenging assays demonstrated that AA-ßG was capable of scavenging 1,1-diphenyl-2-picryl-hydrazyl and hydroxyl peroxide and inhibiting H(2)O(2)-induced hemolysis better than AA. AA-2ßG and AA had similar hydroxyl radical scavenging capabilities, but AA-2ßG was incapable of scavenging superoxide anion radicals, and its capacity to scavenge nitrite (NO(2) (-)) was lower than that of AA. The overall in vitro reduction capability of AA-2ßG was also significantly lower than that of AA. Moreover, in vivo studies demonstrated that AA-2ßG was capable of protecting the liver against carbon tetrachloride-induced acute liver injury in mice. These results suggest that AA-2ßG is an important antioxidant component of Goji berry fruit, which may share similar but distinct antioxidant mechanistic properties with AA. This study furthers our understanding of the mechanisms of Goji berry fruit pharmacological activities on antiaging and antitumor properties as a traditional medicine and dietary supplement.
