Qigong for women with breast cancer: An updated systematic review and meta-analysis.

OBJECTIVE: The purpose of this review was to evaluate the effectiveness of Qigong in improving the quality of life and relieving fatigue, sleep disturbance, and cancer-related emotional disturbances (distress, depression, and anxiety) in women with breast cancer. METHODS: The PubMed, Cochrane Central Register of Controlled Trials, Web of Science, Sinomed, Wanfang, VIP, and China National Knowledge Infrastructure databases were searched from their inceptions to March 2020 for controlled clinical trials. Two reviewers selected relevant trials that assessed the benefit of Qigong for breast cancer patients independently. A methodological quality assessment was conducted according to the criteria of the 12 Cochrane Back Review Group for risk of bias independently. A meta-analysis was performed by Review Manager 5.3. RESULTS: This review consisted of 17 trials, in which 1236 cases were enrolled. The quality of the included trials was generally low, as only five of them were rated high quality. The results showed significant effectiveness of Qigong on quality of life (n = 950, standardized mean difference (SMD), 0.65, 95 % confidence interval (CI) 0.23-1.08, P =  0.002). Depression (n = 540, SMD = -0.32, 95 % CI -0.59 to -0.04, P =  0.02) and anxiety (n = 439, SMD = -0.71, 95 % CI -1.32 to -0.10, P =  0.02) were also significantly relieved in the Qigong group. There was no significant benefit on fatigue (n = 401, SMD = -0.32, 95 % CI  0.71 to 0.07, P = 0.11) or sleep disturbance relief compared to that observed in the control group (n = 298, SMD = -0.11, 95 % CI  0.74 to 0.52, P = 0.73). CONCLUSION: This review shows that Qigong is beneficial for improving quality of lifeand relieving depression and anxiety; thus, Qigong should be encouraged in women with breast cancer.

[Study on surface infrared radiation spectrums of danzhong (CV 17) in the patient of hyperplasia of mammary glands].

OBJECTIVE: To compare differences of surface infrared radiation spectrums between Danzhong (CV 17) A high-sensitive PHE and non-acupoint control point in the patient of hyperplasia of mammary glands. METHODS: 201 surface infrared spectrograph was used to detect infrared radiation spectrums of Danzhong (CV 17) and non-acupoint control point at 1.5-16.0 microm wave band in the patient of hyperplasia of mammary glands. RESULTS: The shape of the infrared spectrums of Danzhong (CV 17) was similar to that of the non-acupoint control point, but with lower radiation intensity. Of the 59 wavelength spots detected, 13 (6.75-8.25 microm, 9.00 microm, 9.25 microm, 9.75 microm, 13.25-13.75 microm) had significant differences in infrared radiation intensity between Danzhong (CV 17) and non-acupoint control point (P<0.05). CONCLUSION: The intensity of infrared radition of Danzhong (CV 17) is lower and Qimen (LR 14) is higher than that of the non-acupoint control point in the patient with hyperplasia of mammary glands, showing that different channels are at different states of deficiency and excess under pathological condition of hyperplasia of mammary glands.
