In the meanwhile, microRNAs have been reported to be effective in inhibiting the expression of several inflammatory\u0000 factors. In the current study, we used rat LDH model to explore the feasibility of MSCs overexpressing microRNA-182-5p as a treatment option for LDH. Changes of inflammatory factors and changes of histological properties of dorsal root ganglion were observed to test the efficacy of this treatment\u0000 option for lower back and extremity pain due secondary to LDH. All the rats survived by the end of eight week study period. The expression of TNF-α, IL-1, IL-6 both in dorsal root ganglia and blood serum were significantly lower in the experimental group than the control group\u0000 (P <0.01). Histopathologic examination results showed better preserved tissue structural integrity of nerve ganglion in rats treated with BMSCs overexpressing microRNA-182-5p. Those results indicated that, BMSCs overexpressing microRNA-182-5p can significantly inhibit inflammatory\u0000 reaction after LDH, and may be used as a therapeutic option to alleviate pain in patients with neurogenic pain after LDH.","PeriodicalId":15300,"journal":{"name":"Journal of Biomaterials and Tissue Engineering","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46413230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single nucleotide polymorphisms (SNPs) play an increasingly important role in predicting the prognosis of patients with HCC.\u0000 In this study, a cohort of 637 HCC patients was enrolled, and various online databases were comprehensively surveyed to identify SNPs that potentially impact HCC patient survival. The results of the Cox regression analysis demonstrated a significant association between rs3094165 and poor prognosis\u0000 among patients with HCC. Further PSM analysis was also employed to control potential biases, and the results remained consistent. These findings suggest that SNPs can serve as reliable prognostic markers for HCC patients. Then, we conducted functional experiments to explore the molecular mechanism\u0000 and confirmed that rs3094165 potentially regulates the progression of HCC by modulating the expression of the NDUFS1. Taken together, our study provides a comprehensive analysis of SNPs associated with HCC prognosis, and highlights the importance of rs3094165 as potential biomarkers for predicting\u0000 poor prognosis of HCC patients.

Results: Gender, place of employment, and specialization comparison between the doctor’s opinion and Fisher’s tests will be analyzed. The post-sale\u0000 service (66.6%), size and prosthesis variety (59%), ease of surgical and prosthetic stages (56.4%), geometry and surface, and kind of connections were the most significant factors. The most relevant element in choosing an implant system was the implant system’s popularity (51.2%), and\u0000 the least relevant aspect was a referral from a dentist (20.5%). One of the insignificant variables in choosing an implant system was the manufacturing country (25.6%).

As an emerging treatment, electroacupuncture (EA)-mediated BBB opening can temporarily increase the permeability of the brain blood vessels to increase\u0000 the concentration of the therapeutic agent in the brain parenchyma, which offers great clinical benefits. Recent studies have suggested that BBB opening with excessive exposure levels may cause tissue/cell damage and short-term behavioral changes. Here, we investigated whether the EA-mediated\u0000 BBB opening cause serious adverse events in the normal rat brain tissue and motor behavior, such as brain tissue damage, histopathologic alteration, or aggravated behavioral changes. EA was performed on the accupoint GV26 and GV20. Evans Blue Assay (EBA) and fluorescein isothiocyanate (FITC)–dextran\u0000 Assay were performed to assess the BBB permeability. Immunofluorescence of GFAP-positive cells was marked and Hematoxylin-eosin (HE) Staining was carried out for assessing brain cortex damage. Tunel Assay was conducted to assess cell apoptosis. ELISA was used to measure the contents of TNF-α\u0000 and IL-1β in brain tissue to explore the inflammatory response. The open field test, balance beam test and Y-Maze test were carried out to assess and neural behaviour. EA can induce an increase in BBB permeability on rats, allowing the macromolecular tracer Evans blue (EB) and\u0000 Fluorescein Isothiocyanate (FITC)–Dextran to enter the brain. Histological analysis indicated that there was no obvious red blood cell leakage and a cellular apoptotic response in the brain tissue of rats with EA treatment. In addition, EA stimulation at specific parameters did not impair\u0000 the rats’ motor ability, balance and coordination, and short-term spatial learning and memory.
