Background: Cancer is a complex systemic disease. As a key component of traditional Chinese medicine, acupuncture is a clinically proven medical treatment for many diseases, and it also has preventative effects as it balances the body, allowing it to self-regulate. For cancer patients, acupuncture is widely used as complementary therapy to boost the immune system and reduce the side effects of radiotherapy and chemotherapy. However, few studies have determined how acupuncture against cancer, especially in regulating the intestinal flora of the tumor-burdened mice. Methods: We treated osteosarcoma tumor-burdened mice by using needling on different acupoints and acupoints combination, thereafter determined the effects of acupuncture on tumor growth by using imaging technology in vitro. In addition, intestinal bacteria were analyzed for further understanding the holistic and systemic treatment effects of acupuncture in osteosarcoma tumor-burdened mice. Results: Acupuncture treatment can delay tumor growth and changes of intestinal bacteria in osteosarcoma tumor-burdened mice. In detail, the loss of body weight and the development of tumor volume of mice have been postposed by needling specific acupoints. In addition, acupuncture treatment has delayed the changes of the relative abundance of Bacteroidetes, Firmicutes and Candidatus Saccharibacteria at the phylum level. Moreover, the relative abundance of many bacteria (e.g., Catabacter, Acetatifactor and Aestuariispira) has been regulated by using acupuncture treatment, and the trend of structural changes of these bacteria at the genus level has also been postposed compared to that of the tumor-burdened mice model group. Conclusion: Our results suggest that acupuncture may provide a systemic treatment for cancer. Our findings encourage new and extensive research into the effects of acupuncture on changes of the intestinal microbiome associated with the development of cancer.

Background: In modern society, the incidence of diabetes is increasing yearly, and poor glycemic control can accelerate the progression and severity of diabetic peripheral vascular disease. External treatment with traditional Chinese medicine (TCM) has been widely used in the treatment of diabetes, but there is no systematic review on the external treatment of TCM for diabetic peripheral vascular disease; therefore, this study aimed to conduct a meta-analysis on the clinical efficacy and safety of external treatment of TCM in the treatment of diabetic peripheral vascular diseases. Methods: We searched The Cochrane Library, PubMed, Web of Science, EMBASE, China Science and Technology Journal, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Literature Database, and other sources from their respective inception dates to October 20, 2022, to identify potentially eligible studies. We will use Review Manager 5.4 software provided by the Cochrane Collaborative Network for statistical analysis. We then assessed the quality and risk of the included studies and observed their outcome measures. Results: Changes in the bilateral femoral artery, popliteal artery, dorsal artery diameter, blood flow, ankle/brachial index, and dorsal foot temperature: An overall reduction in symptoms (a reduction in diabetes-related symptoms that occur only during the intervention or as a result of the intervention, including peripheral vascular disease). Conclusion: The objective of this meta-analysis was to investigate the influence of external treatment of traditional Chinese medicine on diabetic peripheral vascular disease and to provide more methods for the clinical prevention and treatment of diabetic peripheral vascular disease.

Background:Primary dysmenorrhea (PD) is a painful disease that severely affects the daily lives of young women. External therapy using traditional Chinese medicine (TCM) is widely used in the clinical treatment of this disease and has achieved a good effect. There are many kinds of TCM external therapies, but the effectiveness, safety, and advantages of various methods have not been confirmed by high-quality meta-analyses. The purpose of this study was to evaluate the efficacy and safety of representative TCM external therapies in patients with PD.Methods:Published randomized controlled trials that assessed the efficacy of these interventions in patients with PD were included. We searched the following electronic databases: PubMed, Cochrane Library, Embase, Web of Science, China Science and Technology Journal, China National Knowledge Infrastructure, Wanfang, and Chinese Biomedical Literature Database and other sources. The main outcomes included menstrual pain intensity and the clinical effectiveness rate. The secondary outcomes were the quality of life and safety. The meta-analysis will be performed using the Review Manager version 5.3 software.Results:We will provide more practical results investigating the efficacy of external TCM therapy with high clinical frequency for PD patients in several respects, including the improvement of menstrual pain intensity, quality of life, and safety.Conclusion:This review systematically reviews the effectiveness and safety of common TCM external therapies for PD and provides clinicians with the best treatment options.Ethics and dissemination:This systematic review aimed to evaluate the efficacy and safety of external TCM therapy for PD. Since all data included were published, the systematic review did not require ethical approval.Registration number:CRD42021297078.
