Objective To systematically sort out the interventional studies on the application of auricular point sticking technique in patients with urinary calculi by means of evidence map analysis in order to understand the distribution of evidence in this field and the problems of the studies. Methods Chinese and English databases such as CNKI, Wanfang, VIP, China Biology Medicine (CBM) Database, PubMed, Cochrane Library, CINAHL complete, Web of Science, Elsevier Science Direct, Embase, etc. were systematically searched to screen for studies related to the application of auricular point sticking technique in patients with urinary calculi. The time frame of the review was from the database construction to June 2024, and the trend of publication, type of literature, sample size in the literature, interventions, distribution of acupuncture points, outcome indexes, and methodological quality of the literature were analyzed by using graphs and text. Results A total of 79 papers were included, including 65 randomized controlled studies, 5 quasi-experimental study, and 9 studies with unclear grouping basis. The overall trend of the number of publications was increasing, and the average sample size was 103.37 patients. The most frequently selected auricular acupuncture points were kidney, ureter, sympathetic point, Shenmen, and bladder, etc., and the endpoint indicators of greater concern were clinical efficacy, pain relief, and stone expulsion, etc. The methodological quality of the literature was not high. Conclusion Auricular point sticking technique has certain advantages in the treatment of urinary calculi, and the selection of acupoints and outcome indicators are diverse. However, most studies have shortcomings in scientific research design, personalized intervention measures, measurement and analysis of outcome indicators, etc. Therefore, more scientific and rigorous large-scale, multi-center randomized controlled studies are needed in the future to provide high-quality evidence-based basis for the application of auricular point sticking technique in patients with urinary calculi.

Objective: To investigate the functions of FABP5 in the carcinogenesis and development of cervical cancer. Methods: The expression of FABP5 was detected in several cervical cancer cell lines (C33A, Siha, Caski, HeLa and HCC94), 206 cases of cervical cancer tissues with stage Ⅰa2-Ⅱa2 and 40 cases of normal cervical tissues by real-time PCR and Western blotting. Then, the cells were infected with lentivirus-mediated siRNA-targeting FABP5. CCK-8 cell proliferation, colony formation, wound healing and transwell assays were used to investigate the effects of FABP5 on in vitro cell proliferation, migration and invasion. And in vivo xenograft model and lung metastasis model were used to observe the transplanted tumor growth and metastasis in female athymic nude mice. Furthermore, the total protein and RNA were extracted from the primary xenografts to determine the expression levels of FABP5, metalloproteinase-2 and metalloproteinase-9 using Enzyme linked immunosorbent assay (ELISA), real-time PCR and Western blotting. Results: FABP5 expression was found to be significantly unregulated in cervical cancer tissues than that in normal cervical tissues (P<0.05). Compared with the Siha-NC group and uninfected group, the expression of FABP5 mRNA and protein in Siha-FABP5-RNAi group was significantly inhibited along with the decrease of cell proliferation, colony formation, wound healing and invasion ability. The clone formation rates of Siha cells in uninfected group, Siha-NC group and Siha-FABP5-RNAi group were (84.6±4.5)%, (84.6±5.1)% and (21.2±2.6)%, respectively. Moreover, the transwell assay showed that invasive cells in three groups were (72.8±4.7)/HPF, (72.6±3.3)/HPF and (21.4±2.3)/HPF, respectively. All of the difference was statistically significant (P<0.05). Furthermore, FABP5 silencing significantly reduced tumor growth and lung metastases in nude mice in vivo (P<0.001). The subcutaneously xenografted volume in uninfected group, Siha-NC group and Siha-FABP5-RNAi group was (921.4±63.0) mm^3, (1 021.4±56.0) mm³ and (139.6±36.0) mm^3, respectively. The real-time quantitative PCR results showed that the relative expression levels of MMP-2 and MMP-9 mRNA were 1.00±0.10 and 1.00±0.10, 1.00±0.10 and 1.00±0.10 as well as 0.34±0.13 and 0.38±0.17 in xenografted tumor tissues of uninfected group, Siha-NC group and Siha-FABP5-RNAi group, respectively. MMP-2 and MMP-9 was significantly downregulated after FABP5 inhibition(P<0.05). Additionally, the protein expression trend of MMP-2 and MMP-9 in three groups was consistent with the mRNA levels. Conclusion FABP5 might promote the carcinogenesis and metastasis of cervical cancer via up-regulating MMP-2 and MMP-9.
