Pyroptosis is a new way of programmed cell death,a number of researches have found that it is associated with a variety of diseases.Inflammasome and caspase protein family play key roles in regulating pyroptosis.Intracellular pattern recognition receptor oligomers under external stimulus,then assemble with apop-totic speck-like protein containing a caspase recruitment domain and caspase precursor into inflammatory com-plex body,thus activation of caspase can induce pyroptosis.While as the upstream regulation mechanism of pyroptosis,inflammasome might be double edged swordfor tumor growth.On the one hand,inflammasome can inhibit the proliferation of tumor cells by inducing pyroptosis;on the other hand,the cumulative effect of the inflammsome can also form a suitable microenvironment for tumor cells and promote tumor growth.

To construct an HSV-1 vector vaccine carrying HIV-1 antigens, HIV-1 gp160, gag, protease and the expression elements were chained together, and then inserted into the internal inverted repeat sequence region of HSV-1 by bacterial artificial chromosome technology. Firstly, HIV-1 gp160 (including type B and C), gag and protease genes were cloned into pcDNA3 in series to generate the pcDNA/gBgp and pcDNA/gCgp, then the recombinant plasmids were transfected into 293FT cells, and HIV-1 antigen was detected from transfected cells by Western blotting. Then the expression cassettes from pcDNA/gBgp and pcDNA/gCgp, comprising HIV-1 antigen genes and expression elements, were cloned into pKO5/BN to generate the shuttle plasmids pKO5/BN/gBgp and pKO5/BN/gCgp. The shuttle plasmids were electroporated into E. coli cells that harbor an HSV-BAC, the recombinant bacteria were screened, and the recombinant DNA was extracted and transfected into Vero cells. The recombinant virus was purified through picking plaques, the virus' DNAs were identified by Southern blotting; HIV-1 antigen was detected from the recombinant HSV-1 infected cells by Western blotting, and the virus' replication competent was analyzed. As the results, gp160 and gag proteins were detected from 293FT cells transfected with pcDNA/gBgp and pcDNA/gCgp by Western blotting. The recombinant bacteria were generated from the E. coli electroporated with pKO5/BN/gBgp or pKO5/BN/gCgp. The recombinant HSV was purified from the Vero cells transfected with the recombinant DNA, the unique DNA fragment was detected from the genome of recombination HSV by Southern blotting; gp120 and gp41 were detected from the infected cells by Western blotting, and the recombinant HSV retained replication competent in mammalian cells. The results indicate that the recombinant HSV carrying HIV-1 gp160, gag and protease genes was generated, the virus retains replication competent in mammalian cells, and could be used as a replicated viral vector vaccine.

OBJECTIVE: To observe the effects of rhubarb aglycone on pathological changes and activity of matrix metalloproteinase in cerebral ischemic tissue in rats with bone marrow mesenchymal stem cell (BMSC) transplantation, and to explore the action mechanisms of rhubarb aglycone in protecting against brain micrangium injury in rats. METHODS: The BMSCs were purified and amplified by methods of adherence and selection in vitro. One hundred and ninety rats were randomly divided into sham-operated group, untreated group, rhubarb aglycone group, BMSC transplantation group (abbreviated as transplantation group) and BMSCs combined with rhubarb aglycone group (abbreviated as combination group). Middle cerebral artery occlusion (MCAO) model was duplicated with nylon thread. Rats of transplantation and combination group were transplanted with BMSCs via carotid artery after 24-hour reperfusion. Rhubarb aglycone was used by intragastric administration in the rhubarb aglycone group and the combination group. The brain samples were taken at 7, 14 and 28 days after transplantation. Brain micrangium pathological changes were observed by light microscope, and immunohistochemical method was used to determine the expressions of immunoglobulin G (IgG), type IV collagen (Col IV), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1). RESULTS: Comparison with the normal control group revealed that brain micrangium in rats in the untreated group was obviously mutilated and damaged, the expression of IgG and MMP-9 increased, and showed a progressively enhanced tendency following the prolongation of reperfusion, while the expressions of Col IV and TIMP-1 were decreased, and TIMP-1 showed a attenuated tendency following the prolongation of reperfusion. Comparing with the untreated group, the improvements of brain micrangium structure in the rhubarb aglycone group (7 days after transplantation), the transplantation group (14 and 28 days after transplantation) and the combination group were significant; expression of IgG and activity of MMP-9 were decreased, while expressions of Col IV and TIMP-1 were increased in the rhubarb aglycone group and the combination group at each time point. The brain micrangium was integral and the expression of Col IV was enhanced in combination group (7 days after transplantation) as compared with those in transplantation group. MMP-9 activity in combination group (14 days after transplantation) was lower than that in the rhubarb aglycone group (14 days after transplantation), while expression of TIMP-1 in combination group also increased significantly as compared with that in transplantation group (28 days after transplantation). CONCLUSION: Rhubarb aglycone can decrease the degradation of basal lamina Col IV and the permeability of brain micrangium in cerebral ischemic rats with BMSC transplantation, and its mechanisms may be related to regulating the balance of MMP-9, especially by increasing the expression of TIMP-1.

OBJECTIVE: To study the protective effects of Naomaitong, a compound traditional Chinese herbal medicine, used together with thrombolysis therapy, on injuries of the lung and stomach in rats with cerebral ischemia. METHODS: Rats were randomly divided into sham-operated group, untreated group, urokinase group (thrombolysis group), Naomaitong group, thrombolysis plus Naomaitong group. Cerebral ischemia was induced in rats by autonomous blood blot and inserted nylon thread. Rats were administrated with thrombolysis therapy through artery 3, 6 and 9 h after cerebral ischemia respectively. Twenty-four hours after the administration, mortality of the rats, and the brain and stomach hemorrhage ratios, as well as the pathological changes of the brain, lung and stomach were observed, and then cerebral infarct size (CIS) and lung water ratio (LWR) were measured. RESULTS: Compared with the sham-operated group, the rat mortality, and the brain and stomach hemorrhage ratios increased, the CIS enlarged, pathological changes of the brain, lung and stomach appeared obvious, and the LWR increased. Naomaitong plus thrombolysis treatment improved the changes above significantly. In the untreated rats with cerebral ischemia, injuries of the brain, lung and stomach were aggravated, the CIS enlarged and the LWR increased in the 9 h group as compared with those in the 3 h group. In the thrombolysis plus Naomaitong group, the pathological changes were improved, the CIS diminished and the LWR reduced. CONCLUSIONS: Injuries of the lung and stomach can be caused by cerebral ischemia, and the impairment was exacerbated following the prolongation of the ischemia. Thrombolysis therapy can cause brain and stomach hemorrhage. Thrombolysis therapy used early can perform protection against the injuries. Naomaitong, used together with thrombolysis, can reduce the mortality, the brain and stomach hemorrhage ratios, and perform protective effects on the injuries of cerebral ischemia.
