Aim To study the effect of oxymatrine (OMT)on protecting human umbilical vein endothelial cells (HUVECs)from toxicity induced by high glucose in vitro.Methods The HUVECs were cultured with medium containing different concentrations of glucose or OMT. The cells were randomly divided into 6 groups:5.5 mmol·L -1 control group(Control),22.2 mmol·L -1 high glucose (22.2 mmol·L -1 ),44.4 mmol·L -1 high glucose (44.4 mmol·L -1 ),control+OMT(control +OMT),22.2 mmol·L -1 high glu-cose +OMT(22.2 mmol·L -1 +OMT),44.4 mmol ·L -1 high glucose +OMT (44.4 mmol · L -1 +OMT).The protective effect of oxymatrine was as-sessed by MTS assays.The expression of A2B in HU-VECs was detected by Real-time quantitative PCR (qPCR)and Western Blot methods.Results The glucose was shown to have caused cytotoxicity in HU-VECs.Oxymatrine (3 μmol·L -1 )was found to have protected HUVECs from glucose toxicity effectively, and reduced the expression of A2B significantly.Con-clusion Oxymatrine can obviously protect HUVECs from cytotoxicity induced by high glucose and the effect is performed partly by decreasing A2B expression.

Intracerebral hemorrhage is a neurological emergency with high disability and mortality. Studies have demonstrated that thrombin formation,erythrocytolysis and iron ions play important roles in the brain injury after intracerebral hemorrhage. This article reviews the mechanisms of thrombin and iron ions in intracerebral hemorrhage-mediated brain injury.

Objective To study the effect of the extract of Chrysanthemum Indicum(CI)on the expression of tumor necro-sis factor-α (TNF-α) and neutrophil function in chronic bronchitis (CB)rats and to explore the therapeutic mechanism for chronic bronchitis. Methods The extract of CI was prepared. Wistar rats were randomly divided into blank control group, model group, Chuanxiling group, and low-, middle-and high-dose CI extract groups. Rat model of CB was established by intratracheal injection with low-dose lipopolysaccharide. After drug intervention, the expression of TNF-α in rat serum and bronchoalveolar lavage fluid was detected by ELISA method. Phagocytic function of the neu-trophil and respiratory burst of the rats were measured by flow cytometry (FCM). Results Compared with the blank con-trol group, the phagocytic function of the neutrophil, respiratory burst of the rats, and the expression of TNF-α in rat serum and bronchoalveolar lavage fluid of the model group were increased significantly. CI extract significantly decreased the abnormal rising of the above indexes. Conclusion Down-Regulation of TNF-α expression, and decrease of the neutrophil phagocytic function and rat respiratory burst may be one of the therapeutic mechanisms of Chrysanthemum In-dicum extract for the treatment of CB.

Objective:To study the effect of Jianpi Qinghua Recipe ( JPQHR) on angiotensin II/NADPH oxidase pathway in 5/6 nephrectomized rat renal failure model and the underlying mechanisms.
Methods:The animals were divided into 4 groups:the sham-operated group, the renal failure group, the JPQHR-treated group and the losartan-treated group. After 60-days therapy, serum nitrogen and creatinine were measured. The expression of angiotensin II type 1 receptor (AT1) protein and the expression of p47phox mRNA in renal tissue was determined. SOD and MDA were also examined.
Results:Compared with the sham-operated group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in the renal failure group were significantly increased. hTe activities of SOD in renal tissue from the renal failure group was signiifcantly down-regulated while MDA was up-regulated (P<0.05). Compared with the renal failure group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in both JPQHR-treated group and losartan-treated group were signiifcantly decreased. hTe activities of SOD in renal tissue from JPQHR-treated group and losartan-treated group were signiifcantly up-regulated whereas the content of MDA were down-regulated (P<0.05). Compared with the losartan-treated group, the activities of SOD in renal tissue from the JPQHR-treated group was obviously increased (P<0.05), the decrease in AT1 protein and p47phox mRNA was more evident but not statistically different (P>0.05). The level of SCr and serum BUN and the content of MDA were also not statistically different (P>0.05).
Conclusion:hTrough decrease the expression of angiotensin II and NADPH oxidase, JPQHR can reduce the oxidative stress in chronic renal failure and delay the renal ifbrosis progression.

To establish a cell model in vitro that stable expressing HBV by integrating HBA1.3 DNA into cell chromosome. The HBV1.3 full-length DNA was obtained by digested pGEM-HBV1.3 plasmid with HindIII and then was linked with PU-21 vector digested by HindIII. This was resulted in generation of a recombined plasmid named PU21-HBV plasmid. The recombined plasmid was introduced into HepG2 cells by electroporation. The transfected cells were screened with G418. The insertion and expression of HBV were identified by X-gal staining, RT-PCR and Southern blot. The result of PU21-HBV plasmid sequence demonstrated that HBV1.3 DNA was linked correctly with PU-21 vector. A series of positive cell colonies were obtained with G418 screening followed transfecting PU21-HBV plasmid into HepG2 cells. The results of Southern blot and RT-PCR exhibit that HBV1.3 DNA had successfully integrated into the chromosomes of HepG2 cells and had functional HBV gene transcription. HBV1.3 DNA was inserted into HepG2 genome and could stable transcript HBV RNA. The stable HBV expression cell line was constructed successfully. There are LoxP sites in the trapping vector PU21. With the Cre enzyme, interesting genes could be excganged into the LoxP sites. Therefore, double stable expression of interesting gene and HBV cell lines could be generated. The cell lines will be useful for further research some target gene function on replication of HBV.
