e compared with the data of the LGT group. Data from low-, medium- and high-dose Morin groups showed no statistically significant differences (
<0.05).

The findings suggest that Morin improved experimental autoimmune thyroiditis in rats through regulating NLRP3/Caspase-1 pathway.

The purpose of this study was to investigate the protective effect of astragaloside Ⅳ (AS-Ⅳ) on neonatal rats' hypoxic/reoxygenated (H/R) injured myocardial cells and to explore its underlying mechanism.

Cardiac cells were extracted from newborn rats and divided into control, H/R, H/R-low AS-Ⅳ (0.1 μmol/L AS-Ⅳ), H/R-medium AS-Ⅳ (1 μmol/L AS-Ⅳ), H/R-high AS-Ⅳ (10 μmol/L AS-Ⅳ) and H/R-high AS-Ⅳ-AKT (10 μmol/L AS-Ⅳ+5 μmol/L AKT) groups. After 48 h of treatment, the contents of LC3-Ⅱ, p62, AKT, pAKT, rapamycin (mTOR) mammalian targets and uncoordinated 51-like kinase 1 (ULK1) in cardiac myocytes were compared. Immunofluorescence staining was used to detect the expression of P62 in myocardium autophagosome.

AS-Ⅳ improved the proliferative activity of cardio AS-Ⅳ improved the proliferative activity of cardiomyocytes in H/R injury in a dose-dependent manner and inhibited the level of cell autophagy. However, when AKT inhibitors were added, the effect of AS-Ⅳ was partially inhibited (
<0.05). Gene and protein expression showed that AS-Ⅳ had no significant effect on the expression of AKT and mTOR genes (
>0.05), but could significantly promote the phosphorylation of AKT and mTOR (
<0.05). Immunofluorescence staining results showed that high concentrations of the AS - Ⅳ can reverse H/R injury induced the expression of autophagy body P62.

AS-Ⅳ showed protection effect on H/R injured myocardial cells. selleck compound The possible mechanism is by reducing the autophagy level via activating the mTOR signal in the PI3K/AKT pathway, thereby preventing H/R damage in neonatal rat cardiomyocytes.

To investigate the effect of acrolein on the proliferation of pulmonary epithelial cells and its possible mechanism.

Two strains of pulmonary epithelial cells, A549 cells and MLE15 cells, were used as
models of pulmonary epithelial cell, and were treated with 80 μmol/L acrolein or phosphate buffer saline (PBS) as the control. The proliferation of pulmonary epithelial cells were determined with CCK-8 kit after cell culturing resumed for 12 h, 24 h, 36 h and 48 h post acrolein treatment, and the expression of period circadian regulator gene 1 (
1) was examined using Western blot test 24 h after acrolein treatment. In addition, after acrolein treatment, the cells were restored with transforming growth factor-β (TGF-β) added in the medium, and the cell proliferation and the expression of Per1 protein were also examined.

The proliferation of A549 cells and MLE15 cells decreased significantly after being treated with 80 μmol/L acrolein for 30 min, and the expression of Per1 protein was also downregulatedthat in cells restored in medium without TGF-β after acrolein treatment.
To investigate whether long-term exposure to inhaled sevoflurane, a volatile anesthetic, causes abnormal activities and memory impairment related to attention-deficit/hyperactivity disorder (ADHD) in neonatal rats.

On postnatal day 5 (P5), Sprague-Dawley rats were randomly assigned to two sevoflurane subgroups and two control subgroups and underwent experimental intervention. The two sevoflurane (SEVO) subgroups were exposed to 3% sevoflurane for 2 h and 4 h respectively, while the two control subgroups were given pure oxygen for the same amount and duration. Behavioral tests, including open-field test (OFT), five-choice serial reaction time task (5-CSRTT), fear-conditioning (FC) and Morris water maze (MWM), were applied to evaluate changes in cognition, memory, anxiety and ADHD-related behavioral changes in the rats in adolescence (-P25) and in adulthood (-P65).

In OFT, the SEVO 2 h and SEVO 4 h subgroups displayed activity level and exploratory behaviors similar to those of the control subgroups on P2ced compared to that the control group (
=0.048).

The findings suggest that four hours of inhaled sevoflurane exposure in neonate rats may cause memory impairment, but does no increase risks for ADHD-related abnormal activities.

To examine the infectivity of human adenovirus type 55 (HAdV-55) in human intestinal cells.

Caco-2 cells were cultured
, and infected with HAdV-3, 7, 14 and 55. The expression of viral proteins in infected cells was detected with immunofluorescence method. The intracellular and supernatant viral DNA levels were determined with fluorescent quantitative PCR at different points of time. The level of infectious virus particles in the supernatant of Caco-2 cells was determined with adenovirus sensitive HEp-2 infection assay.

Immunofluorescence assay showed positive result for the expression of HAdV-55 virus protein in Caco-2 cells 48 h post infection. HAdV-3, 7, 14, and 55 showed sustained replication and proliferation in Caco-2 cells. The level of viral DNA in infected cells and the supernatant increased with the infection time, and the viral DNA level of HAdV-55 was significantly higher than those of HAdV-3, 7 and 14. The infectious virus particles of HAdV-55 in Caco-2 supernatant were more than those of HAdV-3, 7 and 14, showing statistically significant difference (
<0.05). Caco-2 cells were infected with low doses of virus (1×TCID
), and the cytopathic effect (CPE) of HAdV-55 infection wells was more significant than that of HAdV-3, 7 and 14 infection wells.

This study found that human intestinal cells were susceptible to HAdV-55, and the infection level was higher than that of other common respiratory infections caused by adenovirus types 3, 7 and 14.
