Alcoholic liver disease (ALD) is a growing global health concern, and its early pathogenesis includes steatosis and steatohepatitis. Inhibiting lipid accumulation and inflammation is a crucial step in relieving ALD. Evidence shows that puerarin (Pue), an isoflavone isolated from Pueraria lobata, exerts cardio-protective, neuroprotective, anti-inflammatory, antioxidant activities. However, the therapeutic potential of Pue on ALD remains unknown. In the study, both the NIAAA model and ethanol (EtOH)-induced AML-12 cell were used to explore the protective effect of Pue on alcoholic liver injury in vivo and in vitro and related mechanism. The results showed that Pue (100 mg·kg-1) attenuated EtOH-induced liver injury and inhibited the levels of SREBP-1c, TNF-α, IL-6 and IL-1β, compared with silymarin (Sil, 100 mg·kg-1). In vitro results were consistent within vivo results. Mechanistically, Pue might suppress liver lipid accumulation and inflammation by regulating MMP8. In conclusion, Pue might be a promising clinical candidate for ALD treatment.

Extracorporeal membrane oxygenation (ECMO), a kind of life support technology that can replace lung and heart function, is widely used in critical respiratory and circulatory exhaustion. Because of the serious diseases and the use of interventional catheters, patients receiving ECMO life support are often administrated with broad-spectrum antimicrobial agents, which increase the risk of fungal infection. Fungal infection during ECMO can increase mortality. How to effectively control fungal infection is a thorny problem faced by clinicians. During the treatment of ECMO, the patient's physiological status, ECMO oxygenation membrane, circulation pipeline and other factors may change the pharmacokinetic profiles of antifungal drugs, thereby affect the clinical efficacy of drugs. This artical reviews the pharmacokinetic characteristics of antifungal drugs during ECMO support, in order to provide references for clinical antifungal treatment.

Background::NOTCH1 mutation is an essential molecular biologic aberration in chronic lymphocytic leukemia (CLL). CLL patients with NOTCH1 mutation have shown an unfavorable survival and a poor response to chemoimmunotherapy. This study aims to present the mechanisms of adverse prognosis caused by NOTCH1 mutation from the perspective of the splicing factor heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1). Methods::The microarray data in Gene Expression Omnibus datasets were analyzed by bioinformatics and the function of hnRNPA1 was checked by testing the proliferation and apoptosis of CLL-like cell lines. Afterward, quantitative reverse transcription-polymerase chain reaction and Western blotting were applied to explore the relationship among NOTCH1, c-Myc, and hnRNPA1.Results::RNA splicing was found to play a vital part in NOTCH1-mutated CLL cells; hence, hnRNPA1 was selected as the focus of this study. Higher expression of hnRNPA1 validated in primary NOTCH1-mutated CLL samples could promote proliferation and inhibit apoptosis in CLL. The expression of hnRNPA1 increased when NOTCH1 signaling was activated by transfection with NOTCH1 intracellular domain (NICD)-overexpressed adenovirus vector and declined after NOTCH1 signaling was inhibited by NOTCH1-shRNA. Higher expression of c-Myc was observed in NICD-overexpressed cells and hnRNPA1 expression was downregulated after applying c-Myc inhibitor 10058-F4. Moreover, in NICD-overexpressed cells, hnRNPA1 expression decreased through c-Myc inhibition. Conclusion::Overexpression of c-Myc-dependent hnRNPA1 could promote proliferation and inhibit apoptosis in NOTCH1- mutated CLL cells, which might partly account for the poor prognosis of patients with NOTCH1 mutation.

Acetaminophen (APAP) overdose is the leading cause of drug-induced liver injury, and its prognosis depends on the balance between hepatocyte death and regeneration. Sirtuin 6 (SIRT6) has been reported to protect against oxidative stress-associated DNA damage. But whether SIRT6 regulates APAP-induced hepatotoxicity remains unclear. In this study, the protein expression of nuclear and total SIRT6 was up-regulated in mice liver at 6 and 48 h following APAP treatment, respectively.

The aim of the present study was to investigate the effects and mechanisms of lidocaine on lipopolysaccharide(LPS)-induced matrix metalloproteinase(MMP)-9 and MMP-2 activity in plasma, and the effects of lidocaine on LPS-induced acute lung injury(ALI). Mice were pretreated with lidocaine(2, 4, 8 mg/kg )for 30 minutes, and then treated with 10 mg/kg LPS(ip)for 12 h to induce ALI. The 7-day survival rate and lung wet/dry weight ratio of mice were monitored. Phosphorylation level of p38 was measured by western blot. The activity of MMP-9 and MMP-2 in plasma was evaluated by gelatin zymography. The results showed that pretreatment with lidocaine could significantly reduce the death rate of ALI mice as well as the lung wet/dry weight ratio in a dose-dependent manner and suppress the activity of MMP-9 and MMP-2 in plasma. Moreover, lidocaine also markedly inhibited LPS-induced upregulation of p-p38 in a dose-dependent manner. In conclusion, lidocaine alleviated LPS-induced acute lung injury by suppressing MMP-9 and MMP-2 activity.

Objective To investigate the effects of Tianxiang capsule on Neurotransmitters and Hormone Level of rats with motion sickness. Methods Male SD rats were randomly divided into six groups, including blank control group, model control group, positive drug control group, low-dose, mid-dose and high-dose Tianxiang capsule groups with the method of random digital table, and every group had 10 mice. Except the normal group, the rats in the other groups were intragastrically pre-administered for 1 hour, and the low, medium and high doses of Tianxiang capsule were 0.91, 1.82, 3.64 g/kg, the positive drug control group was given scopolamine 1 mg/kg, and then the rat motion sickness model was induced by a rotary stimulation device. After the modeling, the feces, urine, standing hair, trembling were immediately observed and recorded, and the halo response index of the rats was calculated. The blood from the heart puncture was taken and the vestibular nucleus were put on the ice. Then, the content of histamine (HIS) in the vestibular nucleus and plasma was detected by ELISA. The expression of plasma cortisol (Cort) and arginine vasopressin (AVP) were measured by radioimmunoassay. Results Compared with the model control group, the motion sickness index of rats with low, medium and high doses of Tianxiang capsule (6.56 ± 2.16, 6.10 ± 1.35, 4.46 ± 2.50 vs. 8.90 ± 2.61) significantly decreased (P<0.05 or P<0.01). The HIS content in the vestibular nucleus (12.70 ± 3.86 μg/L, 11.45 ± 1.57 μg/L, 10.02 ± 1.30 μg/L vs. 17.50 ± 4.82 μg/L) significantly decreased (P<0.05 or P<0.01). The plasma content of HIS (4.24 ± 1.75 μg/L vs. 7.69 ± 3.06 μg/L), Cort (286.90 ± 8.72 ng/ml vs. 329.26 ± 29.04 ng/ml) and AVP (16.54 ± 2.48 pg/ml vs. 22.35 ± 3.08 pg/ml) in the high doses of Tianxiang capsule significantly decreased (P<0.05 or P<0.01). Conclusions The Tianxiang capsule could effectively reduce the motion sickness index of rats with motion sicknes, which might be related to the down-regulation of HIS in Vestibule Nucleus and HIS, Cort and AVP in plasma.
