    This finding indicates that to reduce population heat vulnerability, the most important approach is to improve the health status of the whole population and reduce baseline mortality; additionally, regional-specific measures and emphasis should be adjusted reasonably along with the process of urbanization according to the characteristics and key factors of local heat vulnerability.

    Senkyunolide I (SEI), a component of a Chinese herb named Ligusticum Chuanxiong hort, which is included in the formulation of Xuebijing Injection, a medication used to treat sepsis in China. Our previous study showed that SEI was protective against sepsis-associated encephalopathy and the present study was performed to investigate the role of SEI in sepsis-induced lung injury in a murine model of cecal ligation and puncture (CLP).

    SEI (36mg/kg in 200μl) or vehicle was administered immediately after CLP surgery. The lung injury was assessed 24h later by histopathological tests, protein concentration in the bronchoalveolar lavage fluid (BALF), neutrophil recruitment in the lung tissue (myeloperoxidase fluorescence, MPO), pro-inflammatory cytokines and oxidative responses. Platelet activation was detected by CD42d/GP5 immunofluorescence and neutrophil extracellular trap (NET) were determined by immunofluorescence assays and enzyme linked immunosorbent assay (ELISA) of MPO-DNA. In vitro experiments were perfod by SEI treatment (P<0.05 compared with DMSO+CLP group). In vitro experiments showed that the MPO-DNA level stimulated by PMA was significantly reduced by SEI treatment (P<0.05 compared with DMSO treatment). Co-culture neutrophils with platelets from CLP mice resulted in higher level of MPO-DNA complex, while SEI partly reversed such effects of platelet on NET formation.

    SEI was protective against lung injury induced by CLP in mice. The NET formation was significantly reduced by SEI treatment, which might be involved in the mechanism of the protective effect.

Thirty adult male Wistar rats were randomly divided into five equal groups and were subjected to various treatment regimens for eight weeks as follows control group, vehicle control group, VC group orally received VC (120 mg/Kg BW/day), BL-treated group intramuscularly injected with BL (5 mg/kg BW, once/week), and BL+VC group received BL and VC. At the end of this experiment, blood and tissue samples (thyroid, thymus, and spleen) were subjected to hematological evaluation, biochemical analysis, histopathological, and immunohistochemical examinations. In comparison to controls, BL significantly increased the levels of serum proinflammatory interleukins (IL-1 β and IL-6), immunoglobulins (IgG and IgM), and complement 3 but reduced anti-inflammatory interleukin-10, lysosome, and nitric oxide. Besides, altered pnt of BL abuse.

    Coronavirus disease 2019 (COVID-19) has been a serious obstacle in front of public health. Interferon-beta 1a (IFN-β 1a) has been used to treat patients with COVID-19. We aimed to compare the effectiveness of high-dose IFN-β 1a compared to low dose IFN-β 1a in severe COVID-19 cases.

    In this randomized, controlled, and clinical trial, eligible patients with confirmed SARS-CoV-2 infections were randomly assigned to receive one of the two following therapeutic regimens The intervention group was treated with high-dose IFN-β 1a (Recigen) (Subcutaneous injections of 88μg (24 million IU) on days 1, 3, 6)+lopinavir /ritonavir (Kaletra) (400mg/100mg twice a day for 10days, orally) and the control group was treated with low-dose IFN-β 1a (Recigen) (Subcutaneous injections of 44μg (12 million IU) on days 1, 3, 6)+lopinavir /ritonavir (Kaletra) (400mg/100mg twice a day for 10days, orally).

    A total of 168 COVID- 19 confirmed patients underwent randomization; 83 were assigned to the intervention group and 85 were assigned to the control group. Median Time To Clinical Improvement (TTIC) for cases treated with low-dose IFN-β1a was shorter than that for cases treated with high-dose IFN-β1a (6 vs 10days; P=0.018). selleck The mortality rates in intervention and control group were 41% and 36.5%, respectively.

    The use of high-dose IFN-β 1a did not improve TTCI in hospitalized patients with moderate to severe COVID-19. Also, it did not have any significant effect on mortality reduction compared with treating with low-dose IFN-β 1a.

    This trial has been registered as ClinicalTrials.gov, NCT04521400.

Recent studies have shown that TIM-3 is also expressed on other immune cells, such as macrophages, dendritic cells, and monocytes. In addition, TIM-3 ligands also include Psdter, High Mobility Group Box 1 (HMGB1) and Carcinoembryonic antigen associated cell adhesion molecules (Ceacam-1), which have different effects upon biding to different ligands on immune cells. Studies have shown that TIM-3 plays an important role in autoimmune diseases, chronic viral infections and tumors. A large amount of experimental data supports TIM-3 as an immune checkpoint, and targeting TIM-3 is a promising treatment method in current immunotherapy, especially the new combination of other immune checkpoint blockers. In this review, we summarize the role of TIM-3 in different diseases and its possible signaling pathway mechanisms, providing new insights for better breakthrough immunotherapy.The developmental environment can have powerful, canalizing effects that last throughout an animal’s life and even across generations. Intergenerational effects of early-life conditions may affect offspring phenotype through changes in the hypothalamic-pituitary-adrenal axis (HPA). However, such effects remain largely untested in altricial birds. Here, we tested the impact of maternal and paternal developmental conditions on offspring physiology and morphology in the zebra finch (Taeniopygia guttata). Specifically, we exposed one generation (F1) to elevated corticosterone (CORT) during development and quantified the impact on offspring (F2) phenotype. We predicted that intergenerational effects would be apparent through effects of parental developmental treatment on offspring body mass, growth, body condition, body composition, and CORT levels. We found an intergenerational impact on CORT levels, such that F2 birds reared by CORT-treated fathers had higher baseline CORT than F2 birds reared by control fathers.
