10 compounds were predicted to have therapeutic potentials for treating UC. Among them, we selected meclofenamic acid to identify its therapeutic effect on UC treatment by animal experiments.
 
  The current study comprehensively analyzed the DEGs and immune infiltration in UC, as well as screened for potential agents for UC treatment.

  Ionizing radiation (IR) induces injuries to the hematopoietic and intestinal systems, which are the leading cause of death. Baicalein, a plant-derived flavonoid, shows anti-oxidative stress, anti-apoptosis, anti-inflammation effects in many diseases. In this study, we evaluated the effects and mechanism of baicalein on IR induced intestinal and hematopoietic injuries.
 
  Mice were divided into three groups Control, IR and IR+Baicalein. All of mice were intraperitoneally administered with 100mg/kg baicalein or normal saline for 1h before IR, and then a day post-IR. The changes in intestinal structure, function and molecular expression were observed by pathological experiments and western blot. 16S rRNA gene sequencing was performed to analyze gut microbiota and further predicted metabolic pathways through Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Hematopoietic function was evaluated by peripheral blood cells count and by flow cytometry analysis of hematopoietic cells composition.
 
  Baicalein improved intestinal structure and the ability of proliferation and regeneration after mice exposed to IR, in which the rebalance of gut microbial composition played an important role. KEGG results showed that p53-related apoptotic pathways played important roles in the composition changes of gut microbiota. Then we observed that baicalein inhibited the activation of p53 and p53 mediated mitochondrial apoptosis and death receptor apoptosis in the intestine. In addition, IR induced injuries to hematopoietic system also could be ameliorated by baicalein.
 
  These results provide new insights into the mechanism of baicalein and support the potential of baicalein as a radioprotective medicine.

AKI is considered one of the main drawbacks of the use of gentamicin that critically limits its clinical use. In this study, pirfenidone, an oral antifibrotic drug, was given to rats (200 mg/kg, p.o., daily) for seven days alone before the initiation of gentamicin treatment and continued for seven days alongside daily gentamicin injections. In gentamicin group, gentamicin was given to Wistar rats (100 mg/kg, i.p., daily) for seven days to induce AKI. Pirfenidone managed to alleviate gentamicin-induced AKI by improving kidney function parameters including serum creatinine, blood urea nitrogen (BUN), proteinuria, relative kidney-to-body weight ratio and creatinine clearance. Pirfenidone decreased cytotoxicity induced by gentamicin by decreasing lactate dehydrogenase (LDH) activity and improving histologic picture of tubules and glomeruli. Pirfenidone also alleviated oxidative stress induced by gentamicin by reducing malondialdehyde (MDA) and elevating reduced glutathione (GSH). Pirfenidone prevented the upregulated inflammasome pathway markers in the kidney. It succeeded in decreasing toll like recpetor-4 (TLR4), nuclear factor-kappa B (NF-κB), nucleotide-binding oligomerization domain [NOD]-like pyrin domain containing protein 3 (NLRP3), caspase-1, interleukin-1β (IL-1β) and IL-18 levels. Additionally, Pirfenidone caused a decrease in macrophage infiltration displayed by reduction in renal monocyte chemoattractant protein-1 (MCP-1) levels. To sum up, pirfenidone can effectively mitigate gentamicin-induced AKI by inhibiting oxidative stress, macrophage infiltration and inflammasome-dependent NLRP3 pathway-induced inflammation.
  This study aims to investigate the effects of intrauterine perfusion of granulocyte colony-stimulating factor (G-CSF) on a thin-endometrium rat model.
 
  Twenty rats in two groups of 10 were used. Group I was perfused with normal saline (NS) in the right uterine horn and 95% ethanol in the left one. Group II was bilaterally perfused with 95% ethanol into the uterine horns. After three estrous cycles, Group II was perfused with NS in the right uterine horn and G-CSF (30μg/kg) in the left one. Hematoxylin-eosin (HE) and immunohistochemistry (IHC) staining were used to detect changes in endometrial thickness and expression of cytokeratin 19 (CK19) and vimentin (Vim). The relative expression levels of vascular endothelial growth factor (Vegf) and leukemia inhibitory factor (Lif) were also tested via reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and Western-blot analyses.
 
  G-CSF treatment significantly increased the thickness of the endometrium in the 95% ethanol-induced thin-endometrium rat model. The expression levels of endometrial glandular epithelial cell marker for CK19 and stromal cell marker Vim were augmented in the G-CSF-treated group compared with the control group. Moreover, G-CSF treatment stimulated the expression of VEGF and LIF in the 95% ethanol-induced thin-endometrium rat model.
 
  G-CSF intrauterine perfusion improved endometrial receptivity in the thin-endometrium rat model by stimulating endometrial proliferation and angiogenesis.

Previous little evidence showed that DHCR24 (3-β-hydroxysteroid-Δ-24-reductase), also known as seladin-1 (selective Alzheimer's disease indicator-1), exerted potential anti-inflammatory property, however, the link between DHCR24 and microglial polarization has never been reported. Thus, the role of DHCR24 in microglial polarization in amyloid-beta 25-35 (Aβ25-35) treated BV-2 cells was evaluated in this study. Our results demonstrated that Aβ25-35 aggravated inflammatory response and facilitated the transition of microglia phenotype from M2 to M1 in BV-2 cells, by upregulating M1 marker (i-NOS, IL-1β and TNF-α) and downregulating M2 marker (arginase-1, IL-4 and TGF-β).
