Objective: To observe the clinical efficacy of electroacupuncture (EA) in controlling myopia in children and its effect on retinal blood flow. Methods: Sixty-eight myopic children were randomly divided into an observation group and a control group, with 34 cases in each group. The control group was given auricular acupressure treatment alone, and the observation group was treated with EA once a week in addition to the treatment used in the control group. The spherical equivalent refraction (SER) and axial length (AL) were measured at baseline, and after 3 months and 6 months of treatment. Optical coherence tomography angiography was used to measure the vessel density (VD) and perfusion density (PD) in the surface layer of the retina. Results: After 3 months and 6 months of treatment, the changes in SER between the two groups were not statistically significant (P>0.05). After 3 months of treatment, the changes in AL between the two groups were not statistically significant (P>0.05); after 6 months of treatment, the change amount of AL in the observation group was smaller than that in the control group (P<0.05); after 3 months and 6 months of treatment, the changes in VD and PD in the surface layer of the retina in the observation group were significantly greater than those in the control group (P<0.01). Conclusion: EA treatment once a week for 6 months can delay the increase of AL and improve the retinal surface blood flow in myopic children.

[Abstract] Objective: To explore the expression of long non-coding RNA (lncRNA) GTSE1-AS1 in prostate cancer tissues and the mechanism that affects the proliferation and invasion of LNCaP cells. Methods: From November 2017 to December 2018, 68 pairs of prostate cancer tissue and para-cancerous tissue specimens were resected from prostate cancer patients at the Department of Urology of Luoyang Central Hospital Affiliated to Zhengzhou University; in addition, prostate cancer cell lines LNCaP, PC-3, C4-2B, 22Rv1, DU-145 and normal prostate follicular epithelial RWPE-1 cells were also chosen for this study. qPCR was used to detect the expression level of GTSE1-AS1 in cancer tissues and cell lines. The GTSE1-AS1 over-expression plasmid (experimental group) and negative control plasmid (control group) were respectively transfected into LNCap cells. MTT assay and Transwell chamber method were used to detect the effect of GTSE1-AS1 over-expression on the proliferation and invasion ability of LNCaP cells, respectively. The targeting relationship among GTSE1-AS1 and miR-324-3P as well as FBXW7 (F-frame/WD repeat domain protein 7) was verified by bioinformatics tools and dual-luciferin reporter gene assay. The effect of GTSE1-AS1 over-expression on downstream gene and protein expression was detected by qPCR and WB assay. Results: The expression level of GTSE1-AS1 in prostate cancer tissues was significantly lower than that in para-cancerous tissues (P<0.01), and the expression of GTSE1-AS1 in prostate cancer cell lines was significantly lower than that in RWPE-1 cells (P<0.05 or P<0.01). Over-expression of GTSE1-AS1 significantly inhibited the proliferation and invasion (P<0.05 or P<0.01) of LNCaP cells. Dual-luciferin reporter gene assay confirmed the complementary binding between GTSE1-AS1 and miR-324-3p as well as between miR-324-3p and FBXW7. Over-expression of GTSE1-AS1 significantly reduced the expression of miR-324-3p in LNCaP cells (P<0.01), and promoted the mRNA and protein expressions of FBXW7 (all P<0.01). Conclusion: GTSE1-AS1 is under-expressed in prostate cancer tissues and cell lines. Over-expression of GTSE1-AS1 can inhibit the proliferation and invasion of LNCaP cells, the mechanism of which may be related with the inhibition of miR-324-3p to further promote FBXW7 expression.
