Objective To investigate the effect of long non-coding RNA small nucleolar RNA host gene 14(LncRNA SNHG14)on high glucose-induced podocyte injury by targeting microRNA-30a-5p(miR-30a-5p).Methods Podocytes were cultured in vitro and were divided into the following groups:the standard glucose(NG)group,the high glucose(HG)group,the si-NC+HG group,the si-SNHG14+HG group,the miR-NC+HG group,the miR-30a-5p mimics+HG group,the si-SNHG14+inhibitor NC+HG group and the si-SNHG14+miR-30a-5p inhibitor+HG group.Quantitative real-time polymerase chain reaction(RT-qPCR)was performed to detect expression levels of LncRNA SNHG14 and miR-30a-5p.Flow cytometry was used to determine cell apoptosis.Enzyme-linked immunosorbent assay(ELISA)was applied to measure levels of tumor necrosis factor-alpha(TNF-α),interleukin(IL)-6 and IL-1β.Xanthine oxidase method,ammonium molybdate colorimetry and thiobarbituric acid method were respectively used to detect superoxide dismutase(SOD),catalase(CAT)and malondialdehyde(MDA).Dual-luciferase reporter gene was conducted to verify the targeting relationship between LncRNA SNHG14 and miR-30a-5p.Western blot assay was performed to detect expression levels of apoptosis-related proteins.Results Compared with the NG group,the HG group exhibited increased expression levels of LncRNA SNHG14,cell apoptosis rate,as well as levels of TNF-α,IL-6,IL-1β and MDA,whereas the expression level of miR-30a-5p and levels of SOD and CAT were decreased(P<0.05).Compared with the HG group and the si-NC+HG group,the si-SNHG14+HG group exhibited decreased expression levels of LncRNA SNHG14,apoptosis rate,levels of TNF-α,IL-6,IL-1β and MDA,as well as expression levels of Bax and cleaved caspase-3 proteins,while the expression level of miR-30a-5p,levels of SOD and CAT and the expression level of Bcl-2 protein were increased(P<0.05).Compared with the HG group and the miR-NC+HG group,the miR-30a-5p mimics+HG group showed no significant difference in the expression level of LncRNA SNHG14(P>0.05).Meanwhile,the expression level of miR-30a-5p,levels of SOD and CAT,and expression level of Bcl-2 protein were increased,whereas the cell apoptosis rate,levels of TNF-α,IL-6,IL-1β and MDA,as well as expression levels of Bax and cleaved caspase-3 proteins were decreased(P<0.05).Compared with the si-SNHG14+HG group and the si-SNHG14+inhibitor NC+HG group,the si-SNHG14+miR-30a-5p inhibitor+HG group showed no significant difference in the expression level of LncRNA SNHG14(P>0.05),meanwhile,the expression level of miR-30a-5p,levels of SOD and CAT,and expression level of Bcl-2 protein were reduced,whereas the cell apoptosis rate,levels of TNF-α,IL-6,IL-1β and MDA,as well as expression levels of Bax and cleaved caspase-3 proteins were increased(P<0.05).The dual-luciferase reporter gene assay confirmed that LncRNA SNHG14 targeted and negatively regulated miR-30a-5p.Conclusion The inhibition of LncRNA SNHG14 can target miR-30a-5p to alleviate high glucose induced podocyte injury.

Objective To preliminarily explore the potential efficacy of Xuesaitong Soft Capsule(XST)against post-stroke depression(PSD),and to investigate the material basis of XST's anti-PSD effect based on the metabolomics results to analyze its related pharmacokinetic(PK)characteristics and further analyze the pharmacodynamic(PD)equation of representative ingredients.Methods The initial evaluation of drug effica-cy was conducted by detecting the depressive-like behavior and neurotransmitter levels in rats.The Pearson correlation analysis was employed to analyze the correlation between the main metabolites regulated by XST and the saponin components entering the bloodstream.At various time points after drug administration,the blood concentration of ginsenoside Re and the concentration of norepinephrine(NE)in the serum of PSD rats were measured,and the compartment model was fitted accordingly.Furthermore,the liquid chromatography-mass spectrometry was utilized to determine the content of ginsenoside Re in the liver,spleen,kidney,prefron-tal cortex,hippocampus and striatum of PSD rats.Results Ginsenoside Re showed the optimal correlation by the Pearson correlation analysis.Based on its pharmacokinetic parameters,the pharmacodynamic equation with NE was E=160.462 × Ce/(38.663+Ce).The contents of ginsenoside Re in the liver,spleen,kidney,prefron-tal cortex,hippocampus and striatum of rats were(17.23+11.90),(19.05+5.67),(1.95+0.79),(70.13+6.75),(57.03+3.11),and(72.45+5.45)ng/g,respectively.Conclusion XST could improve the depressive-like behaviors in PSD rats by regulating the expression levels of neurotransmitter NE and 5-HT.Ginsenoside Re may be the pharmacodynamical material foundation for XST's preventative treatment of PSD.

NDFIP1 has been previously reported as a tumor suppressor in multiple solid tumors, but the function of NDFIP1 in NSCLC and the underlying mechanism are still unknown. Besides, the WW domain containing proteins can be recognized by NDFIP1, resulted in the loading of the target proteins into exosomes. However, whether WW domain-containing transcription regulator 1 (WWTR1, also known as TAZ) can be packaged into exosomes by NDFIP1 and if so, whether the release of this oncogenic protein via exosomes has an effect on tumor development has not been investigated to any extent. Here, we first found that NDFIP1 was low expressed in NSCLC samples and cell lines, which is associated with shorter OS. Then, we confirmed the interaction between TAZ and NDFIP1, and the existence of TAZ in exosomes, which requires NDFIP1. Critically, knockout of NDFIP1 led to TAZ accumulation with no change in its mRNA level and degradation rate. And the cellular TAZ level could be altered by exosome secretion. Furthermore, NDFIP1 inhibited proliferation in vitro and in vivo, and silencing TAZ eliminated the increase of proliferation caused by NDFIP1 knockout. Moreover, TAZ was negatively correlated with NDFIP1 in subcutaneous xenograft model and clinical samples, and the serum exosomal TAZ level was lower in NSCLC patients. In summary, our data uncover a new tumor suppressor, NDFIP1 in NSCLC, and a new exosome-related regulatory mechanism of TAZ.

Objective To observe the influences of modified constraint-induced movement therapy (mCIMT)on lower-extremity walking ability and femoral artery blood flow among elderly patients with stroke. Methods Totally 67 patients with stroke were randomly divided into mCIMT group(n =35) aged ( 73.2 ± 5.2 ) years and neurodevelopmental treatment (NDT) group ( n =32) as control aged(76.4 ± 3.8) years.Patients in control group exercised by NDT 2 h/time,2 times/d,5 d/week for 6 weeks. Patients in mCIMT group exercised including: up and down exercise,100-120 times/d; movement flatbed exercise for 16-20 min/d; upstairs and downstairs exercise,balance training,standing in a single leg exercise,mandatory exercise time of lower-extremity about 4 h/d,5 d/week for 6 weeks.The patients were assessed for lower-extremities motor function using maximum walking speed (MWS),Berg balance scale (BBS),timed up to go test (TUGT) and Fugl-Meyer(FMA-L) at pre-treatment and post-treatment.The change of femoral artery blood flow velocity and lumen diameter on the affected lower limb were observed by color Doppler. Results There were no differences in the above scores,lumen diameter and blood flow velocity before treatment between the two groups (P> 0.05).After treatment,the scores of MWS (56.68 ± 6.57vs.45.61 ± 5.34),BBS(46.84 ± 4.05vs.29.84 ± 4.05),TUGT ( 14.55 ± 8.25vs.25.35 ± 8.70)were higher in mCIMT group than in NDT control group (t=15.09,17.38,15.25,all P=0.001)while no difference in FMA-L score between the two groups was found (35.24 ± 7.62 vs.31.32 ±3.28,t=19.99,P>0.05).Lumen diameter of femoral artery [(9.05±1.15) mm vs.(8.05±0.68)mm,t=6.72,P=0.001] and blood flow velocity[(92.55±18.25)cm/s vs.(69.35 8.7)cm/s,t=6.83,P=0.001] were increased in mCIMT group as compared with NDT group. Conclusions The mCIMT therapy is better in improving the lower-extremity walking function and blood flow velocity of femoral artery.
