OBJECTIVE To investigate the clinical characteristics of drug-induced liver injury （DILI） induced by glucagon- like peptide-1 receptor agonists （GLP-1RAs）， and to provide a reference for safe clinical medication. METHODS Using search terms such as “GLP-1”“GLP-1RAs”“semaglutide” “drug-induced liver injury”， relevant studies from PubMed， Embase， the Cochrane Library， CNKI， Wanfang Data and VIP were retrieved. Descriptive analysis was performed on cases of DILI induced by GLP-1RAs. RESULTS A total of 11 studies， comprising 11 patients， were included. Among them， 4 were male （36.4%） and 7 were female （63.6%）. Patient ages ranged from 17 to 64 years； 5 patients （45.5%） were between 50 and 65 years old. Six patients were treated for diabetes， and five for weight loss. Ten patients had underlying diseases. The shortest time to the onset of DILI was 5 days after medication， while the longest was approximately 180 days. The DILIs induced by GLP-1RAs were mainly hepatocellular injury type （6 cases）； severity levels included severe （3 cases）， moderate （6 cases）， and mild （2 cases）. Gastrointestinal symptoms and jaundice were the most common clinical manifestations. The association between DILI and GLP- 1RAs was assessed as “probable” in 10 cases and “possible” in 1 case. All 11 patients improved after drug discontinuation and （or） corresponding treatment. CONCLUSIONS DILI induced by GLP-1RAs is relatively concentrated in patients aged 50-65， with a higher incidence in females. The risk may be further increased in patients with underlying diseases. Clinical use of these agents should enhance pharmaceutical care， including identification of high-risk populations and patient education （especially symptom recognition）. When relevant symptoms appear， the drug should be discontinued immediately， with liver-protective therapy initiated when necessary， to ensure patient safety of drug use.

ObjectiveTo investigate the mechanism of Xuefu Zhuyu capsules against atherosclerosis via regulating polarization of macrophages based on Notch1/jagged canonical Notch ligand 1（Jagged1）/Hes family BHLH transcription factor 1（Hes1） signaling pathway. MethodThe mouse models with atherosclerosis were prepared by feeding the mice with an ApoE^-/- high-fat diet for four weeks， and they were randomly divided into the model group， Xuefu Zhuyu capsule group， and atorvastatin group. C57BL/6 mice were fed as a normal group. The Xuefu Zhuyu capsule group was intragastrically given Xuefu Zhuyu capsules （0.728 g·kg^-1·d^-1）， and the atorvastatin group was intragastrically given atorvastatin tablet （6.07 mg·kg^-1·d^-1）. The normal group and the model group were given equal volume of the deionized water by intragastric administration， and the intervention lasted for 12 weeks. Aortic plaque morphology was observed by hematoxylin-eosin （HE） staining， and aortic plaque area and lipid deposition were observed by oil red O staining. The positive expression levels of CD86 and CD206 in aortic tissue were detected by immunohistochemistry， and serum levels of tumor necrosis factor （TNF）-α， interleukin（IL）-1β， transforming growth factor （TGF）-β₁， and IL-10 were detected by enzyme-linked immunosorbent assay （ELISA）. The relative mRNA expressions of inducible nitric oxide synthase （iNOS）， arginase-1 （Arg-1）， Notch1， Jagged1， and Hes1 in aortic tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The relative protein expression of iNOS， Arg-1， Notch1， Jagged1， and Hes1 in aortic tissue was detected by Western blot. ResultCompared with the normal group， the model group had significant aortic plaque and lipid deposition， and the expression levels of pro-inflammatory cytokines TNF-α and IL-1β were increased （P<0.01）. The expression level of anti-inflammatory cytokine TGF-β₁ showed a downward trend， but the difference was not statistically significant. The mRNA and protein expressions of iNOS were increased （P<0.01）. The protein expression of Arg-1 was decreased （P<0.01）， and the mRNA expression of related pathway molecule Jagged1， as well as the protein expressions of Notch1， Jagged1， and Hes1 were increased in the model group （P<0.05， P<0.01）. Compared with those in the model group， the plaque area and lipid deposition had a decreasing trend in the Xuefu Zhuyu capsule group， and the expressions of TNF-α and IL-1β showed a downward trend. The expression of TGF-β₁ was increased （P<0.05）， and the expression of macrophage marker CD86 was decreased. The mRNA and protein expressions of iNOS were decreased （P<0.01）. The mRNA and protein expressions of Arg-1 were increased （P<0.05， P<0.01）. Furthermore， the mRNA and protein expressions of Notch1， Jagged1， and Hes1 were decreased （P<0.01）. ConclusionXuefu Zhuyu capsules can reduce aortic plaque area and lipid deposition in mice with atherosclerosis， alleviate inflammation， inhibit M1 macrophages， and promote the expression of M2 macrophages， and the mechanism may be related to the regulation of Notch1/Jagged1/Hes1 signaling pathway.

Background::Acute respiratory distress syndrome (ARDS) is a common cause of respiratory failure in many critically ill patients. Although inflammasome activation plays an important role in the induction of acute lung injury (ALI) and ARDS, the regulatory mechanism of this process is still unclear. When cells are stimulated by inflammation, the integrity and physiological function of mitochondria play a crucial part in pyroptosis. However, the underlying mechanisms and function of mitochondrial proteins in the process of pyroptosis are largely not yet known. Here, we identified the 18-kDa translocator protein (TSPO), a mitochondrial outer membrane protein, as an important mediator regulating nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containing protein 3 (NLRP3) inflammasome activation in macrophages during ALI.Methods::TSPO gene knockout (KO) and lipopolysaccharide (LPS)-induced ALI/ARDS mouse models were employed to investigate the biological role of TSPO in the pathogenesis of ARDS. Murine macrophages were used to further characterize the effect of TSPO on the NLRP3 inflammasome pathway. Activation of NLRP3 inflammasome was preformed through LPS + adenosine triphosphate (ATP) co-stimulation, followed by detection of mitochondrial membrane potential, reactive oxygen species (ROS) production, and cell death to evaluate the potential biological function of TSPO. Comparisons between two groups were performed with a two-sided unpaired t-test. Results::TSPO-KO mice exhibited more severe pulmonary inflammation in response to LPS-induced ALI. TSPO deficiency resulted in enhanced activation of the NLRP3 inflammasome pathway, promoting more proinflammatory cytokine production of macrophages in LPS-injured lung tissue, including interleukin (IL)-1β, IL-18, and macrophage inflammatory protein (MIP)-2. Mitochondria in TSPO-KO macrophages tended to depolarize in response to cellular stress. The increased production of mitochondrial damage-associated molecular pattern led to enhanced mitochondrial membrane depolarization and pyroptosis in TSPO-KO cells. Conclusion::TSPO may be the key regulator of cellular pyroptosis, and it plays a vital protective role in ARDS occurrence and development.

Objective To investigate the role of H9c2-derived exosomes in regulating angiogenesis in rat cardiomyocytes under hypoxia.Methods The hypoxia model of H9c2 cells was prepared by mixed gas method(the hypoxia model group),and the normal cultured cells were used as the control group.The exosomes secreted by the two groups of cells were extracted respectively.The concentration and particle size of exosomes were detected by nanoparticle tracking analysis.The morphology and size of exosomes were detected by transmission electron microscopy.Western blot assay was used to verify the exosome marker proteins.The hypoxia model of human umbilical vein endothelial cells(HUVEC)was established.HUVECs were incubated with H9c2 exosomes and divided into the normoxia group,the hypoxia group,the hypoxia+normal H9c2 exosomes(EXO-C)group and the hypoxia+hypoxia H9c2 exosomes(EXO-M)group.The proliferation,migration and tube formation of HUVECs were detected by CCK-8 method,cell scratch test and Matrigel in vitro three-dimensional forming test.Results The results of exosome identification showed that the particle concentration of H9c2 exosome samples was 1×107-1×1012 particles/mL and the particle size was 40-160 nm in the normoxia group and the hypoxia group.The morphological characteristics were spherical or saucer-like structure,uniform in size and complete in shape.Exosome marker proteins TSG101,CD63 and CD9 were expressed,and there was no expression of negative protein Calnexin.Compared with the normoxic group,the proliferation ability,migration area and migration rate of HUVEC were significantly decreased in the hypoxic group,and the length of tube,the number of branches and the number of nodes were decreased(P＜0.01).Compared with the hypoxia group,the proliferation ability of HUVEC cells was decreased,the migration area was decreased,the migration rate was decreased and the length and number of branches involved in tube formation were further decreased in the EXO-M group(P＜0.05).Compared with the EXO-C group,the proliferation ability of the EXO-M group decreased,the cell migration area decreased and the migration rate decreased(P＜0.01).Conclusion Exosomes derived from hypoxic H9c2 can inhibit the proliferation,migration and tube formation of HUVEC.

Bladder cancer is one of the most common malignancy in the urinary system over the world. Urine cytology and cystoscopy are important tools for bladder cancer diagnosis and recurrence monitoring. However, due to the limited sensitivity and invasive procedure, there is an urgent need to develop new non-invasive and highly sensitive liquid biopsy approaches. Urine biopsy is a research focus in the field and has great potential. This review focused on protein-based urine markers (including NMP22, BTA and UroVysion etc.) and DNA or RNA-based urine markers (including cfDNA, AssureMDx and Xpert BC Monitor etc.), which were used for bladder cancer diagnosis and recurrence monitoring, and summarized the sensitivity and specificity of each biomarker as well as their characteristics in the diagnosis and recurrence surveillance of bladder cancer. This study provides theoretical and empirical support for further optimization and application of these biomarkers in clinical practice.
