BACKGROUND: Numerous literatures have reviewed and analyzed acupuncture and moxibustion for stress urinary incontinence; however, there are some limitations, such as no comprehensive or targeted analysis of the individual efficacy of acupuncture and moxibustion on female patients. OBJECTIVE: To analyze the characteristics of clinical research regarding acupuncture for treating stress urinary incontinence to provide reference for acupuncture in clinical practice. METHODS: Randomized controlled trials (RCTs) related to acupuncture intervention on stress urinary incontinence published before March 15, 2020 were searched in PubMed, Embase, Cochrane Library, Clinical Evidence, CNKI, VIP, WanFang and SinoMed. Bibliometrics was used to extract data and information from the documents that met the inclusion criteria, and Cochrane was used to evaluate the quality of literature. We quantitatively analyzed acupuncture treatment for stress urinary incontinence from the number of publications, diagnostic criteria, treatment methods, selection of acupoints and meridians, frequency and duration of treatment, curative effect standards and outcome indicators, characteristics of acupuncture operation methods, and design of clinical research methods. RESULTS AND CONCLUSION: A total of 115 Chinese and English documents that met the requirements were screened out. The number of publications has been increasing year by year and tends to be stablely increased since 2012. The use of diagnostic criteria and efficacy criteria is not uniform and standardized; treatment methods are mainly acupuncture alone or in combination with other therapies (pelvic floor muscle training and biofeedback), moxibustion alone or in combination with other therapies, acupuncture combined with other therapies. Single acupuncture therapy is mostly body acupuncture and electric acupuncture. The top 10 acupoints used are Guanyuan (RN 4), Zhongji (RN 3), Sanyinjiao (SP 6), Qihai (RN 6), Shenshu (BL 23), Huiyang (BL 35), Zusanli (ST 36), Zhongliao (BL 33), Ciliao (BL 32), Baihui (DU 20). The BL, RN, GB and KI meridians are the most used. Subjective and objective indicators are combined with each other, and the effective rate is the most frequently used as the outcome indicator. Both clinical operation methods and the course of treatment are different in the documents. The quality of methodology and clinical reports are generally poor, and researches with high argumentation intensity are rare. Methods of acupuncture for stress urinary incontinence are various, mainly based on local selection of acupoints combined with acupoints selection along the meridian. The standards of design and method are different in the clinical researches, which need to be standardized and improved in the future. [ABSTRACT FROM AUTHOR]

BACKGROUND: With the continuous development of three-dimensional (3D) printing technology and bone tissue engineering, more and more studies have applied 3D printing technology to bone tissue engineering, but the main research status, hot spots and development trend are not clear enough. OBJECTIVE: To explore the current research status, hotspots and development trends of this field through the literature metrology and visual analysis of research hotspots of 3D printing and bone tissue engineering. METHODS: The CNKI database was searched under the theme of “3D printing and bone tissue engineering research”. Based on the quantitative visual analysis method of CNKI literature, the author made a statistical analysis on the trend of the number of publications, publishing institutions and journals of the application of 3D printing technology in bone tissue engineering. VOSviewer software was used to analyze the author collaboration and keyword co-occurrence network of the literature, and the hot research topic was interpreted based on the literature. RESULTS AND CONCLUSION: (1) A total of 469 effective articles related to 3D printing and bone tissue engineering were retrieved. Since 2014, the research on 3D printing and bone tissue engineering has shown a steady growth trend. Chinese Journal of Tissue Engineering Research and Jilin University are the most published journal and institution in this field, respectively. The authors of the literature form five major groups, but there is very little cooperation between the groups. (2) Keywords co-occurrence network shows that the contents revealed by keywords commonly clustering into four research topics (bone tissue engineering scaffold material, 3D printing technology and its application in orthopedics, 3D printing and joint replacement, and others) and the top 10 keywords (3D printing technology, computer aided technology, bone tissue engineering, tissue engineering, fracture, bone defect, hydroxyapatite, three-dimensional, replacement, titanium alloy) really reflect the present situation and the hotspots of current 3D printing and the bone tissue engineering research, which can provide a reference for researchers in this field when choosing a research direction.
