Relationship between the start time of treatment and patient prognosis in cases of acute wild mushroom poisoning in a certain region of Guizhou Province, China from 2013 to 2020: A retrospective Observational Study and forecast.

Methods: This single-center, retrospective observational study was conducted on 455 patients with Undergoing Treatment for Mushroom Poisoning at Affiliated Hospital of Zunyi Medical University (AHZMU), the tertiary governmental hospital of China, between January 2013 and December 2020. We investigated the impact of prognostic factors, including the mortality rate of patients who completed treatment at AHZMU versus those transferred to AHZMU, average length of hospital stay, mortality rate for a latency period of > 6-h, major damaged organs, HOPE6-TALK scoring and established a predictive model to assess the severity of acute mushroom poisoning.

Results: In 2013-2020, there are 455 patients of mushroom poisoning at AHZMU.

The global, regional, and national burden of foreign bodies from 1990 to 2019: a systematic analysis of the global burden of disease study 2019.

Background: Foreign bodies (FBs) are a common emergency in medical institutions, that can occur in any area and among people of any age, which are common public health problems. Understanding the epidemiological characteristics of FBs is crucial for their prevention and control. The purpose of this study was to analyze the epidemiological characteristics of FBs worldwide through the data from the Global Burden of Disease Study 2019 (GBD 2019).

Actin Alpha 2 Downregulation Inhibits Neural Stem Cell Proliferation and Differentiation into Neurons through Canonical Wnt/-Catenin Signaling Pathway.

Our previous study has shown that actin alpha 2 (ACTA2) is expressed in NSC and ACTA2 downregulation inhibits NSC migration by increasing RhoA expression and decreasing the expression of Rac1 to curb actin filament polymerization. Given that proliferation and differentiation are the two main characteristics of NSC, the role of ACTA2 downregulation in the proliferation and differentiation of NSC remains elusive. Here, the results demonstrated that ACTA2 downregulation using ACTA2 siRNA held the potential of inhibiting NSC proliferation using cell counting kit-8 (CCK8) and immunostaining.

Protective effect of acute splenic irradiation in rats with traumatic brain injury.

Objective: To explore the protective effect of acute splenic irradiation against traumatic brain injury (TBI) in rats.

Methods: A rat model of TBI was established according to Feeney's method. Splenic irradiation was performed by the reverse intensity-modulated radiation therapy (IMRT) source-axis distance (SAD) irradiation technique.

[Diffusion tensor imaging and resting-state functional magnetic resonance imaging in patients with delirium in intensive care unit].

Objective: To analyze the brain function of patients with delirium in intensive care unit (ICU) using resting-state functional magnetic resonance imaging (fMRI), further analyze the structural changes in the brain using diffusion tensor imaging (DTI), and explore the correlations of brain function with structural changes in patients with delirium in ICU from a new perspective of functional imaging, provide visual evidence for the diagnosis of delirium.

Methods: Patients with delirium admitted to ICU of the Affiliated Hospital of Zunyi Medical University from January 1st to December 31st in 2017 were enrolled as subjects. During the same period, the healthy volunteers who matched the gender, age and education level of the patients with delirium were enrolled as control group.

Interleukin 17A exacerbates ER-stress-mediated inflammation of macrophages following ICH.

IL-17A contributes to the initiation of inflammation following intracerebral hemorrhage (ICH). Endoplasmic reticulum (ER) stress acts on protein folding and contributes to inflammatory diseases. The role of IL-17A in the regulation of ER stress following ICH has not been well characterized.

[Protective effect of 5-aminosalicylic acid on the kidney of paraquat poisoning rats by Nrf2-ARE signal pathway].

Objective: To investigate the protective effect of 5-aminosalicylic acid (5-ASA) on renal injury poisoned by paraquat (PQ) in rats and its mechanism.

Methods: Twenty-four healthy clean male Sprague-Dawley (SD) rats were randomly divided into four groups: normal saline (NS) control group, 5-ASA control group, PQ model group and 5-ASA treatment group, with 6 rats in each group. The rat model of PQ poisoning was reproduced by intraperitoneal injection of 2% PQ solution 20 mg/kg, and the same volume of NS was given in NS control group and 5-ASA control group.

IL-17A promotes microglial activation and neuroinflammation in mouse models of intracerebral haemorrhage.

Microglial activation is an important contributor to neuroinflammation in intracerebral haemorrhage (ICH). IL-17A has been demonstrated to be involved in neuroinflammatory diseases such as multiple sclerosis. However, the exact mechanism of IL-17A mediated microglial activation in ICH has not been well identified.

[Therapeutic effects of gastric lavage with fuller earth combined with QingyiII catharsis in treatment of oral paraquat poisoning in rabbits].

Objective: To observe the therapeutic effects of gastric lavage with fuller earth combined with Qingyi II catharsis in treatment of oral paraquat poisoning in rabbits.

Methods: Thirty healthy adult Japanese white rabbits were randomly divided into five groups: namely control group, model group, gastric lavage group (lavage of 10% fuller earth suspension), catharsis group (Qingyi II catharsis), and combination group (10 minutes after gastric lavage of fuller earth suspension liquid, giving Qingyi II for catharsis), with 6 rabbits in each group. All groups were challenged with paraquat (100 mg/kg) diluted to 5 mL with normal saline by lavage to reproduce the model of acute poisoning, while the control group was given 5 mL of normal saline instead.
