Objective To investigate how puerarin affects cognitive behavior and pro-inflammatory factors in the hippocampal formation of 52％(v/v)alcohol exposure/withdrawal in mice and reveal the underlying neuroimmunological mechanism by which puerarin improves alcohol-induced cognitive dysfunction.Methods A total of 120 adult female mice were randomly divided into control,52％alcohol,puerarin+52％alcohol,and normal saline(NS)+52％alcohol groups.The cognitive function of the animals was assessed using the Morris water maze,and the expression of target proteins in the hippocampal formation was detected using Western blotting and immunohistochemi-stry.Results The cognitive ability of mice in the puerarin+52％alcohol group was significantly higher than that of mice in the 52％alcohol and NS+52％alcohol groups.At the 20th hour after alcohol withdrawal,IL-6,TNF-α,and IL-1β expressions in the hippocampal formation of the puerarin+52％alcohol group were higher than those of the 52％and NS+52％alcohol groups.However,no significant difference could be observed in the expression levels of these cytokines between the puerarin+52％alcohol and control groups.Con-clusion In a female mouse model chronically exposed to 52％alcohol,puerarin can improve cognitive dysfunction during acute alcohol withdrawal,potentially related to the involvement of puerarin in regulating pro-inflammatory factor expressions in murine hippocampus formation.

MicroRNA(miRNA)serves as a novel regulatory factor in viral and bacterial co-infections,exhibiting dual regulatory roles during pathogen infections.On the one hand,it exerts protective effects by modulating viral replication cycles and host anti-infection immune responses.On the other hand,it can be exploited by pathogens to promote infection progression,including influencing viral replication,antiviral immune responses,and regulating bacterial adhesion and proliferation.Mixed viral and bacterial infections lead to high mortality rates.By binding to specific target gene mRNA,miRNA degrades or inhibits its translation,thereby regulating target gene expres-sion,which may ultimately serve as potential diagnostic and therapeutic targets.This paper reviews recent ad-vances in research on the role of miRNA in viral and bacterial infections,particularly its mechanisms in co-infec-tions,aiming to provide theoretical reference for further research on the infection mechanisms.

OBJECTIVES: To investigate the effect of orexin-A-mediated regulation of ionotropic glutamate receptors for promoting motor function recovery in rats with spinal cord injury (SCI). METHODS: Thirty-six newborn SD rats (aged 7-14 days) were randomized into 6 groups (n=6), including a normal control group, a sham-operated group, and 4 SCI groups with daily intrathecal injection of saline, DNQX, orexin-A, or orexin-A+DNQX for 3 consecutive days after PCI. Motor function of the rats were evaluated using blood-brain barrier (BBB) score and inclined plane test 1 day before and at 1, 3, and 7 days after SCI. For patch-clamp experiment, spinal cord slices from newborn rats in the control, sham-operated, SCI, and SCI+orexin groups were prepared, and ventral horn neurons were acutely isolated to determine the reversal potential and dynamic indicators of glutamate receptor-mediated currents under glutamate perfusion. RESULTS: At 3 and 7 days after SCI, the orexin-A-treated rats showed significantly higher BBB scores and grip tilt angles than those with other interventions. Compared with those treated with DNQX alone, the rats receiving the combined treatment with orexin and DNQX had significantly higher BBB scores and grip tilt angles on day 7 after PCI. In the patch-clamp experiment, the ventral horn neurons from SCI rat models exhibited obviously higher reversal potential and greater rise slope of glutamate current with shorter decay time than those from sham-operated and orexin-treated rats. CONCLUSIONS Orexin-A promotes motor function recovery in rats after SCI possibly by improving the function of the ionotropic glutamate receptors.

Liver sinusoidal endothelial cells (LSECs) are the highest proportion of liver non-parenchymal cells with fenestrae structure and high endocytic ability maintaining liver homeostasis and playing an indispensable role in the physiology and patholo-gy of the liver.LSECs are involved in the regulation of patholog-ical process in nonalcoholic fatty liver disease(NAFLD),alco-holic fatty liver(AFL),hepatocellular carcinoma(HCC),liverregeneration and liver fibrosis mainly via antiinflammation,endocytosis,secretion of angiocrine signals and maintaining thequiescence phenotype of HSCs.This review highlights the physiological function of LSECs and the different roles in different pathological conditions,which aims to provide a new perspectivefor the treatment of liver diseases through targeting LSECs.

Objective To investigate the correlation between anxiety, depression and quality of life in patients undergoing in vitro fertilization and embryo transfer. Methods The psychological status of patients undergoing in vitro fertilization and embryo transfer in Nanjing General Hospital of Nanjing Military Command from November 2016 to March 2017 was investigated with the method of purposive sampling. Results The survey released a total of 300 questionnaires with effective recovery of 280, the effective recovery rate was 93.33%. The score of anxiety scale was (55.16 ± 3.92) points, the score of depression scale was (55.62 ± 8.45) points. Nearly 87%(244/280) patients showed anxiety symptom, and 48%(134/280) patients showed depression symptom. The score of quality of life was (62.55±12.09) points, and the anxiety and depression were negatively correlated with the quality of life (r=-0.581,-0.544). Multivariate regression analysis showed that factors affecting the fertility quality of life scores including anxiety, depression, age, educational level, family income, infertility years, type of infertility, previous receiving assisted reproductive history. Conclusions The patients with in vitro fertilization and embryo transfer show different degrees of anxiety and depression, and is correlated with quality of life. Medical staff should pay more attention to the psychological status of patients, adopt targeted interventions to improve anxiety and depression status of patients, help patients to actively take effective coping style to improve the quality of life of patients, improve the clinical pregnancy rate.

Nicotinamide adenine dinucleotide phosphate oxidase ( NOXs) contributes to the production of reactive oxygen species ( ROS) in liver fibrosis, resulting in the activation of endoplas-mic reticulum stress ( ERS ) and IRE1α-XBP1 signaling path-way. ROS is a series of oxygen metabolites and its derivatives, produced by the single electron reduction of molecular oxygen ( O2 ) , including superoxide anion ( O2- ) , hydroxyl radical (-OH) , hydrogen peroxide ( H2 O2 ) , hypochlorite ion ( OCl-) and so on. They can interact with a large number of molecules, including small inorganic molecules, proteins, lipids, carbohy-drates and nucleic acids, resulting in lipid peroxidation of cell damaging molecules. And as a second messenger, ROS can also affect the proliferation and activation of HSC in liver fibrosis, and induce the hepatocyte apoptosis through a variety of cellular signal transduction. Here we review the current status of the study on the mechanism of NOXs in liver fibrosis.
