Objective. This study aims to systematically assess the efficacy and safety of auricular therapy for cancer pain. Methods. A systematic search was conducted using PubMed, EMBASE, Cochrane library databases, CNKI, VIP, WanFang Data, and CBM for randomized controlled trials (RCTs). Review Manager 5.3 was used for meta-analysis. Results. Of the 275 screened studies, nine RCTs involving 783 patients with cancer pain were systematically reviewed. Compared with drug therapy, auricular therapy plus drug therapy has significant advantages both in the effective rate for pain relief (RR = 1.40; 95% CI 1.22, 1.60; P<0.00001) and adverse effects rate (RR = 0.46; 95% CI 0.37, 0.58; P<0.00001). And the result revealed that auricular acupuncture had superior pain-relieving effects as compared with sham auricular acupuncture (SMD = -1.45; 95% CI -2.80, -0.09; P=0.04). However, the analysis indicated no difference on the effective rate for pain relief between auricular therapy and drug therapy (RR = 1.24; 95% CI 0.71, 2.16; P=0.46). Conclusion. Our meta-analysis indicated that auricular therapy is effective and safe for the treatment of cancer pain, and auricular therapy plus drug therapy is more effective than drug therapy alone, whether in terms of pain relief or adverse reactions. However, the included RCTs had some methodological limitations; future large, rigor, and high-quality RCTs are still needed to confirm the benefits of auricular therapy on cancer pain.

Objective. This study aimed to investigate the efficacy of acupoint injection for alleviating side effects of chemotherapy in people with cancer. Methods. PubMed, EMBASE, Cochrane library databases, CNKI, VIP, WanFang Date, and CBM were searched for randomized controlled trials (RCTs) from inception through December 28, 2020. This meta-analysis was performed using Review Manager 5.3. Results. A total of 8 RCTs including 557 participants were eligible and included in the meta-analysis. The selected RCTs studied acupoint injection for alleviating side effects of chemotherapy in people with cancer. Statistically significant improvements were observed for the incidence of nausea and vomiting (RR = 0.39; 95% CI 0.26, 0.58; P  < 0.00001), the number of leukocyte (MD = 1.89; 95%CI 0.74, 3.03; P  = 0.001), and the number of platelet (MD = 28.82; 95%CI 19.33, 38.30; P  < 0.00001). Two of these studies suggested that acupoint injection can also reduce some other adverse reactions, which showed a statistical difference (RR = 0.29; 95% CI 0.11, 0.75; P  = 0.01). Conclusion. The analysis indicated that acupoint injection can alleviate side effects of chemotherapy in people with cancer. However, due to the high risk of bias and small sample size in the included studies, the results need to be further confirmed by further large, rigorously designed trials.

Life cycle cost (LCC) is introduced into product design stage, and consideration of LCC in the product's design process is the trend of science development. The product's creditability (RMS) is the most active factor of LCC, only attach importance to RMS when the project begins, can LCC make a real cut down. Fully considerating LCC in the design process of hyperstatic hydraulic support, and applying innovative structure and simple design can promote the RMS and reduce the LCC of hyperstatic hydraulic support, which can bring great economic benefits for enterprises.
