ABSTRACT
BACKGROUND: To compare and rank the clinical effects of different acupuncture and acupuncture-related therapies on patients with poststroke cognitive impairment. METHODS: We evaluated the direct and indirect evidence from relevant studies using network meta-analysis. Eight databases were examined in order to find randomized controlled trials of acupuncture-related therapies for individuals with poststroke cognitive impairment. After 2 researchers independently scanned the literature, extracted the data, and assessed the risk of bias in the included studies, the data were analyzed using RevMan5.4, Stata15.0, and WinBUGS1.4.3 software. RESULTS: We assess the benefits and drawbacks of various acupuncture-related therapies, rank the efficacy of various acupuncture-related therapies in the treatment of poststroke cognitive impairment, and describe the best acupuncture intervention approaches or combinations based on the available data. CONCLUSION: This study will contribute to the existence of data on the safety and efficacy of acupuncture-related therapies in the treatment of poststroke cognitive impairment, and it may aid clinical guideline makers in selecting the best acupuncture treatment for poststroke cognitive impairment.

Long non-coding RNAs (lncRNAs) were playing critical roles in tumorigenesis. However, in prostate cancer, the roles and mechanisms of lncRNAs especially ANRIL were largely unknown. We investigated the effects of ANRIL on the proliferation and migration of prostate cancer cells using CCK-8 assay and Transwell migration assay. Real-time PCR and western blotting assays were used to analyze the levels of ANRIL, let-7a, TGF-ß1, p-Smad2 and p-Smad7. Our results showed that ANRIL was significantly overexpressed in prostate cancer tissues compared with corresponding normal tissues. Knockdown of ANRIL significantly inhibited the proliferation and migration of prostate cancer LNCap, PC3 and DU145 cells. Knockdown of ANRIL significantly decreased the levels of TGF-ß1 and p-Smad2, and increased the level of p-Smad7 in prostate cancer LNCap cells. We further found that knockdown of ANRIL significantly enhanced the expression of let-7a, and rescue experiment found that let-7a inhibitor recovered the suppressive effects of ANRIL silencing on the proliferation and migration of prostate cancer LNCap, PC3 and DU145 cells. And let-7a inhibitor recovered the suppressive effects of ANRIL silencing on the activity of TGF-ß1/Smad signaling pathway in prostate cancer LNCap cells. Taken together, our findings indicated that overexpression of lncRNA ANRIL promoted the proliferation and migration of prostate cancer cells via regulating let-7a/TGF-ß1/Smad signaling pathway.
