Efficacy and safety of warm acupuncture combined with Western medicine for sciatica: A protocol for systematic review and meta-analysis.

BACKGROUND: There are more and more clinical studies on the efficacy of warm acupuncture in treating sciatica, but the systematic review of the efficacy of warm acupuncture is still lacking. The objective of this study was to evaluate the efficacy and safety of warm acupuncture combined with conventional Western medicine in the treatment of sciatica. METHODS: The review was registered in the PROSPERO database (CRD42022379486) and was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The following databases will be used to search the existing literature (from inception to January 2023): Web of Science, Embase, Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature, Wanfang, Allied and Complementary Medicine Database, China Knowledge Network, and SPORT-Discus. Included studies are considered eligible if they met the population, intervention, comparator, outcomes, and study design criteria as follows: Population: patients with newly diagnosed sciatica; Intervention: warm acupuncture combined with conventional Western medicine; Comparator: Western medicine alone; Outcomes: total response rate, pain score and pain threshold, adverse events and recurrence rate. Study design: randomized controlled trials or non-randomized cohort studies. Review Manager (RevMan) V.5.3 will be used to perform statistical analyses and to generate forest plots. RESULTS: The review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

The Potential Inhibitory Effects of miR-19b on Ocular Inflammation are Mediated Upstream of the JAK/STAT Pathway in a Murine Model of Allergic Conjunctivitis.

Purpose: Thymic stromal lymphopoietin (TSLP) is a pro-allergic cytokine that initiates allergic inflammatory reaction between epithelial and dendritic cells (DCs). miR-19b was reported to suppress TSLP expression. The present study aimed to examine miR-19b expression, regulation, and function in allergic conjunctivitis (AC). Methods: A murine model of experimental AC was induced in BALB/c mice by short ragweed pollen. The serum, eye balls, conjunctiva, and cervical lymph nodes (CLN) were used for the study. Gene expression was determined by RT-PCR, whereas protein production and activation were evaluated by immunostaining, ELISA, and Western blotting. Results: In the murine AC model, miR-19b was aberrantly downregulated, whereas the levels of TSLP and p-STAT3, as well as the number of CD11c+ pSTAT3+ DCs were increased. Moreover, Th2 inflammatory cytokine expression was significantly increased. These severe phenotypes could be counteracted by either applying exogenous miR-19b mimic microRNAs or the JAK/STAT inhibitor CYT387. Moreover, overexpression of miR-19b repressed p-STAT3 expression and the number of CD11c+ cells in AC eye and CLN tissues. Conclusions: These findings suggested that miR-19b reduced ocular surface inflammation by inhibiting Stat3 signaling via TSLP downregulation in a murine AC model. Moreover, the present study further demonstrated the clinical potential of applying miR-19b and anti-JAK/STAT therapies in the treatment of AC.
