High mobility group box 1 (HMGB1), a ubiquitous non-histone protein in the nuclear chromatin of eukaryotic cells, plays an important role in inflammatory diseases, autoimmune diseases and cancer. The function of HMGB1 in the development and progression of tumor varies with its subcellular localization. On one hand, HMGB1 promotes the growth, proliferation, invasion and metastasis of tumor cells, and mediates immune escape and immune tolerance; on the other hand, HMGB1 possesses anti-tumor activity by maintaining the stability of genome, regulating the expression of tumor suppressor genes, inhibiting cell invasion and metastasis and improving the anti-tumor therapeutic effect. In recent years, increasing evidences have suggested that HMGB1 is closely associated with the development of tumor. Therefore, understanding the function of HMGB1 in cancer will provide enlightenment for preventive and therapeutic strategies. This review summarized the dual role of HMGB1 in tumor progression.

Intracerebral hemorrhage (ICH) is a common type of stroke in clinic. At present, its diagnosis and prognosis are mostly based on CT image features. Hematoma expansion is an important determinant for poor prognosis and high mortality in ICH patients. Prediction of hematoma expansion after ICH is very important for its treatment and prognosis. CT and its image features, such as CT plain scan, CT enhanced scan, radiomics and artificial intelligence, have been widely used in predicting hematoma expansion in recent years. This article reviews the research progress of CT image features in predicting hematoma expansion after ICH, in order to provide help for its prevention and treatment in clinical practice.

Objective:To observe the intervention mechanism of phlegm-stasis co-treatment for the JNK signaling pathway in the myocardium of diabetes rats.Methods:Totally 50 male SD rats of SPF grade were selected. Diabetes model was established by single intraperitoneal injection of 55 mg/kg streptozotocin (STZ) solution. After continued feeding for 3 weeks, the rats were divided into normal group, model group, alachloramine group, blood stasis removing group, phlegm removing group and phlegm-blood stasis co-treatment group according to random number table method, with 6 rats in each group. Xiaoxianxiong Decoction (4.05 g/kg), Xuefu Zhuyu Decoction (7.02 g/kg), Didang Xianxiong Decoction (8.10 g/kg) were administered to the stomach respectively in the phlegm removing group, the blood stasis removing group and the phlegm-blood stasis co-treatment group. Alachloramine (3 mg/kg) was administered to the stomach by gavage in the alachloramine group. After 8 weeks, HE staining was used to observe the morphological changes of myocardial tissue in diabetic rats. Masson staining was used to observe the deposition of collagen fibers in the myocardial interstitium in rats. The expression of JNK1 protein was determined by immunohistochemistry. JNK1 mRNA, IRS1 mRNA and NLRP3 expression levels were detected by Real-time PCR. Western blot was used to detect the protein expressions of IRS-1, p-Akt and NLRP3.Results:The myocardial cells in the model group were disorganized, with hypertrophy, blurred texture, inflammatory infiltration of interstitium, increased collagen fibers, and focal necrosis. All treatment groups could improve fibrosis, inflammatory infiltration and reduce myocardial collagen deposition in different degrees. Compared with the model group, the mRNA and protein expressions of JNK1 and NLRP3 bodies decreased ( P<0.01), the IRS-1 mRNA and protein increased ( P<0.01), and p-Akt protein expression increased ( P<0.01). Conclusions:The phlegm and stasis co-treatment can effectively improve the cardiomyopathy of diabetes rats, and the effect is better than the phlegm-resolving method or the stasis resolving method alone. The mechanism may be related to the inhibition of JNK signaling pathway activation, reduce the expressions of JNK1 and NLRP3, and increase the IRS-1 and Akt.

Objective:To investigate whether hepatitis B virus X protein (HBx) mediates the podocyte injury through reactive oxygen species (ROS) /nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) signaling pathway.Methods:HBx-overexpressing lentivirus was transfected into renal podocytes of mouse to mimic the pathogenesis of hepatitis B virus-associated glomerulonephritis. Podocytes were divided into the following five groups: blank control group (no special treatment), negative control group (transfected with control lentivirus), HBx overexpression group (transfected with HBx overexpression lentivirus), HBx overexpression+NLRP3 siRNA group (transfected with HBx overexpression lentivirus and NLRP3 siRNA), and HBx overexpression+ROS inhibitor group (transfected with HBx overexpression lentivirus and adding ROS inhibitor). The morphological changes of podocytes were observed with electron microscope. The generation of ROS was detected by dichlorodihydrofluorescein diacetate assay (DCFH-DA). Hoechst 33342 staining was used to observe the morphological and quantitative changes of podocyte nuclei. Enzyme-linked immunosorbent assay was used to detect caspase-1 activity, and the levels of lactate dehydrogenase, interleukin (IL)-1β and IL-18. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression levels of mRNA and protein of pyroptosis-related protein, such as NLRP3, apoptosis-associated speck-like protein containing card (ASC), caspase-1, IL-1β and IL-18. TUNEL staining and flow cytometer were used to detect the number of pyroptosis cells. Immunofluorescence staining was used to detect the expression levels of desmin and nephrin.Results:After successful infection of podocytes with HBx-overexpressing lentivirus, pyroptosis-related morphological changes in the cells were observed under electron microscope. The level of ROS in the HBx overexpression group was significantly higher compared to the negative control group ( P<0.05). Hoechst 33342 staining revealed condensed nuclei in the HBx overexpression group. TUNEL staining and flow cytometer demonstrated that podocytes underwent increased pyroptosis in the HBx overexpression group. The mRNA and protein expression levels of pyroptosis-related proteins such as NLRP3, ASC, caspase-1, IL-1β and IL-18 were up-regulated upon HBx overexpression (all P<0.05). Caspase-1 enzyme activity, lactate dehydrogenase and desmin expression levels were enhanced after HBx overexpression (all P<0.05). However, NLRP3 knockdown or addition of ROS inhibitors attenuated the pyroptosis and increased expression levels of pyroptosis-related proteins caused by HBx overexpression (all P<0.05). Conclusion:ROS/NLRP3 pathway plays an important role in HBx-induced podocyte pyroptosis.
