Baicalin exhibits antibacterial, anti‑viral, anti‑oxidative, antipyretic, analgesic, anti‑inflammatory and anti‑tumor properties. The chemical scavenges oxygen free radicals, protects the cardiovascular system and neurons, protects the liver, and has been used for the prevention and treatment of diabetes‑associated complications. The present study investigated the effect of baicalin on severe burn‑induced remote acute lung injury (ALI). The present study demonstrated that baicalin significantly decreased the lung wet‑to‑dry weight ratio, improved pulmonary histological alterations and reduced the expression of high mobility group protein B1 in the rat model of ALI. In addition, treatment with baicalin decreased tumor necrosis factor‑α, interleukin (IL)‑8, IL‑1β and IL‑18 concentrations in the serum, reduced myeloperoxidase activity and malondialdehyde content, and increased the level of superoxide dismutase in the serum in treated model rats with ALI. As a result, baicalin significantly suppressed nucleotide‑binding oligomerization, NACHT, LRR and PYD domains‑containing protein 3 (NLRP3), caspase‑1, nuclear factor‑κB and matrix metalloproteinase‑9 protein expression in the rat model of ALI. The results of the present study suggested that baicalin may serve a protective role against ALI in rats through the NLRP3 signaling pathway.
MicroRNAs (miRNAs) may function as tumor suppressor or onco‑miRNAs and have critical roles in the pathogenesis of gastric cancer (GC). The exact function and mechanism of miRNA (miR)‑320a in GC remains to be elucidated. The present study performed gain‑ and loss‑of‑function analyses by transfecting cells with mimics or inhibitors and subsequently performing colony formation, proliferation and cisplatin‑sensitivity assays. Additionally, in vivo xenograft models were also performed. Bioinformatics algorithms, luciferase reporter activity assay and western blotting were used to predict the potential target of miR‑320a. Additionally, the effect of knockdown or overexpression of ADAM metallopeptidase domain 10 (ADAM10) on cell growth and chemosensitivity was examined. The expression of miR‑320a and ADAM10 was also determined in primary tumors. The present study revealed that the expression of miR‑320a was reduced in GC cells and ectopic miR‑320a expression significantly inhibited cell growth in vitro and in vivo and enhanced the sensitivity of GC cells to cisplatin. ADAM10 was a direct target of miR‑320a in GC. Knockdown of ADAM10 attenuated the proliferative ability of GC cells, and increased the sensitivity of GC cells to cisplatin. The upregulated ADAM10 accelerated cell growth rate and reduced the cisplatin‑sensitivity of cells. Clinically, a significantly negative correlation was identified between the expression of miR‑320a and mRNA levels of ADAM10 in tumors. The findings of the present study suggested that miR‑320a may function as a tumor suppressor in GC progression and potential therapeutic strategies for GC may be based on the miR‑320a/ADAM10 axis.
In order to determine whether microRNA (miR)-300 is a diagnostic and prognostic biomarker in osteosarcoma, the miR-300 levels in serum of 114 osteosarcoma patients and 114 healthy controls were compared, followed by serum analysis of the differences between the pre-operative and post-operative sera of these osteosarcoma patients. It was observed that the concentration levels of miR-300 in the serum of osteosarcoma patients was significantly higher than those in the serum of healthy controls (P<0.01). Furthermore, the concentration levels of miR-300 in the post-operative serum were significantly reduced when compared with the pre-operative serum levels (P<0.001). High miR-300 levels in serum correlated significantly with clinical stage, distant metastasis and poor survival of osteosarcoma patients. Notably, serum miR-300 was an independent prognostic marker for osteosarcoma. In conclusion, our results suggested that serum miR-300 may be a potential and useful noninvasive biomarker for the early detection of osteosarcoma.
Introduction: Comparison of side-to-side brachiocephalic arteriovenous fistula (BCAVF) with ligation of the perforating vein with end-to-side BCAVF. Report: All side-to-side with ligation of the perforating vein and end-to-side BCAVFs which were created in two hospitals were followed up to determine complications and patency rate of AVFs. Forty-four patients (24 side-to-side) entered the study but two patients censored from analysis due to early mortality. Patients of both groups were free of steal syndrome and venous hypertension. There were no significant differences in maturation time and complications between two groups. Respectively 2 and 3 failures occurred in side-to-side and end-to-side groups (P > 0.05). One year patency rate was 95% and 86% for side-to-side and end-to-side groups respectively. Discussion: Although there was no significant difference regarding primary and secondary access failure during follow up period, one year patency rate was higher in side-to-side group using life table analysis. Also, there was no significant difference regarding complications. This may show end-to-side BCAVF has no superiority to our new technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
