The present study observed the regulatory effect of total flavonoids of Ziziphora clinopodioides on autophagy and the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) signaling pathways in ApoE~(-/-) mice and explored the mechanism of total flavonoids of Z. clinopodioides against atherosclerosis(AS). ApoE~(-/-) mice were fed on a high-fat diet for eight weeks to induce an AS model. The model mice were randomly divided into a model group, a positive control group, and low-, medium-and high-dose groups of total flavonoids of Z. clinopodioides, while C57BL/6J mice fed on a common diet were assigned to the blank group. The serum and aorta samples were collected after intragastric administration for 12 weeks, and the serum levels of total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C), and high density lipoprotein-cholesterol(HDL-C) were detected by an automatic biochemical analyzer. The serum expression levels of intercellular adhesion molecule-1(ICAM-1), vascular cell adhesion molecule-1(VCAM-1), matrix metalloproteinase-2(MMP-2), and matrix metalloprotei-nase-9(MMP-9) were detected by enzyme-linked immunosorbent assay(ELISA). Oil red O staining was used to observe the aortic plaque area in mice. Hematoxylin-eosin(HE) staining was used to observe the aortic plaque and pathological changes in mice. The expression of P62 and LC3 in the aorta was detected by the immunofluorescence method. The protein expression of LC3Ⅱ/Ⅰ, Beclin-1, P62, p-PI3K, p-Akt, and p-mTOR in the aorta of mice was detected by Western blot. The results showed that compared with the blank group, the serum levels of TC, TG, LDL-C, ICAM-1, VCAM-1, MMP-2 and MMP-9 in the model group were significantly increased(P<0.01 or P<0.05), the content of HDL-C was decreased(P<0.05), intra-aortic plaque area was enlarged(P<0.01), the expression of LC3 in the aorta was significantly down-regulated, P62 expression was up-regulated(P<0.01 or P<0.05), the expressions of LC3Ⅱ/Ⅰ and Beclin-1 in the aortic lysate were significantly down-regulated, and the expressions of p-PI3K, p-Akt, p-mTOR and P62 were significantly increased(P<0.01). The medium-and high-dose groups of total flavonoids of Z. clinopodioides could reduce the serum levels of TC, TG, LDL-C, ICAM-1, VCAM-1, MMP-2, and MMP-9 in AS model mice(P<0.01 or P<0.05), and increase the content of HDL-C(P<0.01 or P<0.05). The aortic plaque area of mice after middle and high doses of total flavonoids of Z. clinopodioides was significantly reduced(P<0.01), the content of foam cells decrease, and the narrowing of the lumen decreased. The total flavonoids of Z. clinopodioides significantly increased the expression of LC3 in the aorta and the expression of LC3Ⅱ/Ⅰ and Beclin-1 in the lysate, and decreased the expression of P62 in the aorta and the expression of p-PI3K, p-Akt, p-mTOR and P62 in the lysate(P<0.01 or P<0.05). The results showed that the total flavonoids of Z. clinopodioides could improve the content of blood lipids and inflammatory factors, and reduce the generation of foam cells and plaques in aortic tissue, and the mechanism may be related to the regulation of PI3K/Akt/mTOR signaling pathway.

OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

Polysaccharide is among the main active components of Ganoderma lucidum for tumor prevention and treatment. Howe-ver, it remains unclear whether it has synergy with tumor immunotherapy. This study evaluated the effect of G. lucidum polysaccharides(GLP) on the infiltration of T lymphocytes into tumor and the underlying mechanism, in order to provide a reference for its application in tumor immunotherapy. GLP were prepared by water extraction and alcohol precipitation combined with Sevag method and then given(intraperitoneal injection) to the mice bearing B16-F10 cells at 25, 50 and 100 mg kg~(-1), respectively, to evaluate the effect on tumor growth. The infiltration of CD3~+ and CD8~+ T cells and the expression of intercellular cell adhesion molecule-1(ICAM-1) in tumor were detected by immunohistochemistry. EA.hy926 cells were treated with 50, 100 and 200 μg·mL~(-1) GLP, and the expression of ICAM-1 was determined by Western blot. The adhesion of EA.hy926 cells treated with GLP was measured with fluorescence-labeled Jurkat cells. To analyze the mechanism based on NF-κB pathway, this study determined the protein levels of nuclear factor kappa-B(NF-κB) p65, alpha inhibitor of NF-κB(IκBα), p-NF-κB p65 and p-IκBα by Western blot. The results showed that GLP can significantly inhibit the tumor growth in mice bearing B16-F10 cells, promote the infiltration of CD3~+ and CD8~+ T cells in tumor, and increase the expression of ICAM-1 in tumor. Meanwhile, GLP could also enhance the expression of ICAM-1 in EA.hy926 cells, thus strengthen the adhesion to Jurkat cells, induce phosphorylation and protein degradation of IκBα, and raise the expression and phosphorylation level of NF-κB p65. These results suggested that GLP could promote the expression of ICAM-1 through NF-κB pathway and further enhance the infiltration of T lymphocytes into tumor, thereby inhibiting tumor growth. This study lays a foundation for the further application of GLP in tumor immunotherapy.

Objective To investigate the role of proteasome inhibitor bortezomib (BTZ) in inflammatory response in abdominal aortic aneurysm (AAA) formation induced by angiotensin Ⅱ (Ang Ⅱ). Methods Ang Ⅱ-induced ApoEmice AAA models were established. Forty male ApoEmice (8-10-week-old) were randomly and equally divided into four groups:Sham group,BTZ group,Ang Ⅱ group,and Ang Ⅱ+BTZ group.HE staining,immunohistochemical staining,and flow cytometry were used to analyze the inflammatory response. Real-time quantitative polymerase chain reaction (qPCR) was used to analyze the mRNA expression of intercellular cell adhesion molecule-1 (ICAM-1). Western blotting was used to analyze the activation of nuclear factor κB signaling (NF-κB). Results The mean maximum suprarenal aortic diameter (Dmax) of Sham group,BTZ group,Ang Ⅱ group,and Ang Ⅱ+BTZ group were (1.00±0.01),(0.99±0.01),(1.50±0.13),and (1.20±0.04)mm,respectively (F=8.959,P=0.000). The Dmax of Ang Ⅱ group was significantly larger than those of Sham group (P=0.000) and Ang Ⅱ+BTZ group (P=0.015). The incidence of AAA in Ang Ⅱ group,Ang Ⅱ+BTZ group,and Sham group were 60%,17%,and 0,respectively. HE staining revealed that the abdominal aortic wall thickening was more severe in Ang Ⅱ group than in Sham group and Ang Ⅱ+BTZ group,similar with the infiltration of inflammatory cells. Immunohistochemical staining demonstrated that the CD3T lymphocyte count was significantly higher in Ang Ⅱ group than in Sham group (107.9±15.9 vs. 0,P=0.000) and Ang Ⅱ+BTZ group (107.9±15.9 vs. 0.8±0.5,P=0.000). Flow cytometry also demonstrated that the proportion of the CD3T lymphocytes of the Ang Ⅱ group [(13.50±0.69)%] was significantly higher than that in the Ang Ⅱ+BTZ group [(10.40±0.78)%] at week 1 (t=3.009,P=0.040),and the proportion of the CD3T lymphocytes of the Ang Ⅱ group [(22.70±0.93)%] was significantly higher than that in the Ang Ⅱ+BTZ group [(15.10±0.97)%] at week 4 (t=5.654,P=0.005). The qPCR analysis showed that the mRNA expression of ICAM-1 was significantly up-regulated in Ang Ⅱ group than in Sham group (1.93±0.54 vs. 1.00±0.15,P=0.011) and Ang Ⅱ+BTZ group (1.93±0.54 vs. 0.83±0.08,P=0.009). Western blot analysis showed a lower phosphorylation level of inhibitor of NF-κB in the Ang Ⅱ group compared with the Sham group or Ang Ⅱ+BTZ group,accompanied with an increased phosphorylation level of p65. Conclusion Proteasome inhibitor BTZ can attenuate AAA formation partially by regulating T lymphocytes infiltration through regulating the mRNA expression of ICAM-1 regulated by the activation of NF-κB signaling pathway.

OBJECTIVEThis study observed attenuating effect of hydroxysafflor yellow A (HSYA), an effective ingredient of aqueous extract of Carthamus tinctorius L, on lipopolysaccharide (LPS)-induced endothelium inflammatory injury.

METHODSEahy926 human endothelium cell (EC) line was used; thiazolyl blue tetrazolium bromide (MTT) test was assayed to observe the viability of EC; Luciferase reporter gene assay was applied to measure nuclear factor-κB (NF-κB) p65 subunit nuclear binding activity in EC; Western blot technology was used to monitor mitogen activated protein kinase (MAPKs) and NF-κB activation. Reverse transcription polymerase chain reaction (RT-PCR) method was applied to observe intercellular cell adhesion molecule-1 (ICAM-1) and E-selectin mRNA level; EC surface ICAM-1 expression was measured with flow cytometry and leukocyte adhesion to EC was assayed with Rose Bengal spectrophotometry technology.

RESULTSHSYA protected EC viability against LPS-induced injury (P <0.05). LPS-induced NF-κB p65 subunit DNA binding (P <0.01) and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor α (IκBα) phosphorylation was inhibited by HSYA. HSYA attenuated LPS triggered ICAM-1 and E-selectin mRNA levels elevation and phosphorylation of p38 MAPK or c-Jun N-terminal kinase MAPK. HSYA also inhibited LPS-induced cell surface ICAM-1 protein expression P <0.01) and leukocyte adhesion to EC (P <0.05).

CONCLUSIONHSYA is effective to protect LPS-induced high expression of endothelium adhesive molecule and inflammatory signal transduction.

BACKGROUNDToll-like receptor 4 (TLR4) is a crucial receptor in the innate immune system and noninfectious immune responses. It has been reported that TLR4 participates in the pathological course of ischemia/reperfusion (I/R) injury. However, the role of TLR4 in the process of I/R injury after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) is still unknown. In this study, we investigated the effects of TLR4 mutation on survival and neurological outcome in a mouse model of CA/CPR.

METHODSA model of potassium-induced CA was performed on TLR4-mutant mice (C3H/HeJ) and wild-type mice (C3H/HeN). After 3 min of untreated CA, resuscitation was attempted with chest compression, ventilation, and intravenous epinephrine. Behavioral tests were performed on mice on day 3 after CPR. The morphological changes in hippocampal neurons were assessed by light and electron microscopy. Expressions of TLR4 and intercellular adhesion molecule-1 (ICAM-1) were detected by Western blot. Levels of tumor necrosis factor-α (TNF-α) and myeloperoxidase (MPO) were measured with enzyme-linked immunosorbent assay (ELISA).

RESULTSOn day 3 after resuscitation the overall mortality was 33.33% in C3H/HeJ group compared with 53.33% in C3H/HeN group (P < 0.05). And there was much higher central tendency in C3H/HeJ group than C3H/HeN group during open field test (P < 0.05). Meanwhile, the percentage of nonviable neurons was 21.16% in C3H/HeJ group compared with 53.11% in C3H/HeN group (P < 0.05). And there were significantly lower levels of hippocampal TNF-α and MPO in C3H/HeJ mice (TNF-α: 6.85±1.19 ng/mL, MPO: 0.33±0.11 U/g) than C3H/HeN mice (TNF-α: 11.36±2.12 ng/mL, MPO: 0.54±0.17 U/g) (all P < 0.01). CPR also significantly increased the expressions of TLR4 and ICAM-1 in C3H/HeN group. However, the expression of ICAM-1 was much lower in C3H/HeJ group than in C3H/HeN group after CPR (P < 0.01).

CONCLUSIONTLR4 signaling is involved in brain damage and in inflammation triggered by CA/CPR.

OBJECTIVETo investigate whether I-tetrahydropalmatine (I-THP), an alkaloid mainly present in Corydalis family, could ameliorate early vascular inflammatory responses in atherosclerotic processes.

METHODSFluorescently labeled monocytes were co-incubated with human umbilical vein endothelial cells (HUVECs), which were pretreated with I-THP and then simulated with tumor necrosis factor (TNF)-α in absence of I-THP to determine if I-THP could reduce thecytokine-induced adhesion of monocytes to HUVECs. Then I-THP were further studied the underlying mechanisms through observing the transcriptional and translational level of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and the nuclear translocation of nuclear factor (NF)-κ B in HUVECs.

RESULTSL-THP could block TNF-α-induced adhesion of monocytes to HUVECs and could significantly inhibited the expression of ICAM-1 and VCAM-1 on cell surface by 31% and 36% at 30 μ mol/L. L-THP pretreatment could also markedly reduce transcriptional and translational level of VCAM-1 as well as mildly reduce the total protein and mRNA expression levels of ICAM-1. Furthermore, I-THP attenuated TNF-α-stimulated NF-κ B nuclear translocation.

CONCLUSIONThese results provide evidences supporting that I-THP could be a promising compound in the prevention and treatment of the early vascular inflammatory reaction in atherosclerosis by inhibiting monocyte adhesion to vascular endothelial cell through downregulating ICAM-1 and VCAM-1 in vascular endothelial cell based on suppressing NF-κ B.

To study the protective effect of Danqi Piantan capsule ( DPC) and its antelope horn substitution (DPCAS) on the cerebral ischemia, in order to preliminary study the possibility of replacing antelope horn with artificial bezoar. In this study, the left middle cerebral artery occlusion (MCAO) was adopted. Totally 150 SD rats were randomly divided into 5 groups: the sham operation group, the model group, the Danqi Piantan capsule (DPC) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn (DPCRA) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn and with double artificial bezoar (DPCDB) group (0.246 g x kg(-1) x d(-1)). The MCAO model was prepared 1 h later after the administration on the 5th day. At 24 h after the operation, the inner canthus blood was collected to determine the serum superoxide dismutase (SOD) activity and the endothelin (ET) content. At 72 h after the operation, the cerebral infarct size and the cerebral index were determined by TTC-staining. The fluorescent quantitative PCR method was used to detect brain Bcl-2, Caspase-3, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions. The mmunohistochemical method was used to detect ICAM-1, IL-1β, TNF-α, IL-6 expressions in ischemic penumbra. According to the results, compared with the model group, DPCDB and DPC groups showed almost consistent results, indicating both of the two group can significantly improved cerebral infarction index and cerebral index (P < 0.05), increase the serum SOD activity (P < 0.05), decrease the serum ET level and Caspase-3 expression, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions in brain tissues (P < 0.05) and expressions of ICAM-1, IL-1,6, TNF-α, IL-6 positive cells in ischemic penumbra (P < 0.05) and increase the Bcl-2 expression (P < 0.05). The DPCRA group showed much lower impacts on indexes than DPCDB and DPC groups. This suggests that DPCDB and DPC reveal similar efficacies and antelope horn in Danqi Piantan capsule can be substitutes by artificial bezoar.

OBJECTIVE: In order to understand which kind of function genes play an important role for estimating wound age, the variation of difference genes' mRNA expression were compared after injury. METHODS: The mRNA expression levels of seven candidate genes (ICAM-1, NF-κB, MX2, MT1, MT2, sTnI, and Cox6c) were analyzed in contused rat skeletal muscle at different time points using real-time fluorescent quantitative PCR (RT-qPCR). The raw Ct values were normalized relative to that of RPL32 mRNA, and converted to standard Ct values. At each time point after injury, the standard deviations (SD) of the standard Ct values were calculated by SPSS. RESULTS: The expression trends of the seven genes were all found to be related to wound age, but there were lower variation coefficients and greater reliability of s TnI and Cox6c when compared with other genes. CONCLUSION The genes encoding structural proteins or proteins that perform basic functions can be suitable for wound age estimation.

To study the protective mechanism of Danhong injection on brain microvascular endothelial cells (rBMECs) injured by hypoxic. In the experiment, primary suckling mouse's rBMECs cells were collected and identified with factor VIII to establish the 4 h injury model. Meanwhile, rBMECs were given Danhong injection (25, 50, 100 mL . L-1), and the superoxide dismutase (SOD) activity and the malonyldialdehyde (MDA) level were detected by the biochemical method. Cell MMP-9, ICAM-1 and P53 mRNA expression levels were detected by RT-PCR method. Changes in cells' microscopic structure were observed by transmission electron microscope. According to the results, primary rBMECs were notably injured by hypoxia. Compared with model group, Danhong injection (50, 100 mL . L-1) could remarkably resist the injury induced by hypoxic, increase intracellular SOD activity, decrease MDA level and significantly down-regulate ICAM-1, MMP-9 and P53 mRNA expressions. Danhong injection (100 mL . L-1) could protect the cells' normal morphology and microscopic structure, maintain the close intercellular junction, and inhibit the hypoxia-induced cell apoptosis. The results showed that Danhong injection plays a significant role in protecting rBMECs injured by hypoxia. Its mechanism may be related to the enhancement of cells' antioxidant capacity, the inhibition of inflammatory response and the cell apoptosis.
