To observe the influence of Baicalin and Octreotide on liver and kidney of rats with severe acute pancreatitis (SAP) and discuss the related mechanism. SAP rats were randomly divided into model control, Baicalin treated and Octreotide treated group ( n = 45). The same number of normal rats were included in sham-operated group ( n = 45). In all groups, the mortality rate, pathological changes as well as expression levels of NF-κB p65 and P-selectin protein in liver and kidney were observed at 3, 6 and 12 h after operation. The survival rate of treated group was 100% at 12 h significantly higher than that of model control group ( P < 0.05). The pathological changes of liver and kidney in treated groups were alleviated to different degrees, the NF-κB protein expression levels and pathological severity scores in liver and kidney of treated groups were significantly lower than those of model control group ( P < 0.05 or P < 0.001). The hepatic P-selectin protein expression level in Baicalin treated group was significantly lower than that of model control group at 3 h ( P < 0.01), and renal P-selectin expression level in Baicalin treated group at 3 and 6 h were significantly lower than those of model control group and Octreotide treated group ( P < 0.01). (1) Early treatment with Baicalin or Octreotide have obvious protecting effects on liver and kidney injuries in SAP with their mechanisms associated to inhibiting NF-κB and P-selectin expression of liver and kidney. (2) Comparing the pharmacologic effects of Octreotide and Baicalin, we believe Baicalin as a new drug with its protecting effects on liver and kidney of SAP rats similar to Octreotide is worth further studying. (3) The advantages of tissue microarrays in pathological examination include time and energy saving and highly efficient. But the restriction of small diameter weakens the representation of tissues to various extents, which may lead to the deviation of analysis. [ABSTRACT FROM AUTHOR]

Objective: To explore the potential biological roles of long noncoding RNA (lncRNA) RNCR3 in human hepatocellular carcinoma (HCC)., Methods: First, the expression of RNCR3 was detected by qRT-PCR. Then, in vitro experiments were performed to investigate the effects of RNCR3 on the proliferation, cell cycle, migration, and invasion of HCC cells, while the effects of RNCR3 on HCC tumor growth and metastasis were investigated using in vivo experiments. Finally, western blot was used to study the activation of the Akt/GSK3 β signaling pathway., Results: RNCR3 was highly expressed in both HCC tissues and cells, and the expression of RNCR3 was closely related to tumor size, tumor number, TNM stage, and overall survival time. In vitro , RNCR3 served as an oncogene to promote cell proliferation, migration, and invasion, and in vivo , RNCR3 promoted the growth and metastasis of HCC tumors. In terms of mechanism, RNCR3 induced the phosphorylation of Akt (thr308 and ser473) and GSK3 β (ser9) but decreased the expression of GSK3 β , which activated the Akt/GSK3 β signaling pathway., Conclusion: The high expression of lncRNA RNCR3 in HCC can promote the proliferation, migration, invasion, growth, and metastasis of HCC by activating the NF- κ B signaling pathway., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Qi Xie et al.)
