0 05).Among them,WT but neither DN, Blank, nor Pio significantly ameliorated the increased concentrations of TGF-a1 and fibro nectin in culture medium induced by HG. Compared with DN and Blank, WT transfect ion significantly attenuated high glucose-caused elevation in c-fos, c-jun and p-ERK expression, reduction in Ⅰ-?B level, and incretio n in nucleus/cytosol ratio of NF-?B, while Pio demonstrated similarly signific ant changes only in p-ERK and NF-?B. No significant difference of GLUT-1 mRN A level was detected between HG groups. Conclusions Overexpressed PPAR?1 can su ppress increased ECM production from glomerular mesangial cells cultured in HG c ondition. Its inhibitory effects on activation of ERK/AP-1 and NF-?B pathways are involved. The further increase of PPAR?activity may have direct anti-fibr otic effect in diabetic kidney.

Medicinal properties are specific attributes of traditional Chinese medicines(TCM). The medicinal property theory is an important principle for the compatibility of traditional Chinese medicines. In this paper, medicinal properties, flavors and meridian tropism were combined to represent TCM medicinal properties; and multiple medicinal properties were further combined into medicinal property combination modes. TCMs and medicinal property combination modes were divided according to their efficacies, which were regarded as the concept of inductive logic programming and finally got medicinal property combination and compatibility rules with different efficacies. These medicinal property combination and compatibility rules were used to form the theoretical model through the entity grammar system, realize the automatic reasoning process from the medicinal property combination and compatibility to the efficacies, verify the reasoning result and analyze their rationality and limitations, in order to provide new ideas for revealing the relations between the TCM compatibility rules and efficacies.

Objective To study the influence of Captopril preconditioning on apoptosis and the expression of gp 130 in rats of acute myocardial injured. Method Wistar rats were randomly divided into three groups:control group, Iso group and Cap preconditioning group. Cardiomyocytes apoptosis was detected with TUNEL method. The expressions of Bcl-2 and Bax proteins in myocardium were tested by immunohistochemistry. The expression of gp 130 was tested with Western blot method. Results The index of cardiomyocytes apoptosis was decreased, the expressions of Bax proteins and gp 130 were decreased and the expression of Bcl-2 proteins was increased in Cap preconditioning group compared with Iso group (P<0.01 or P<0.05). Conclusion The expression of gp 130 could be decreased through Cap preconditioning, which can reduce the cardiomyocytes apoptosis.

Objective To observe NLS-KALA-SA-PTX (NKSP) for lung adenocarcinoma cell line A549 in vitro with paclitaxel monotherapy, and the mechanism thereof. Methods MTT assay was used to detect A549 cell proliferation influ-enced by different concentrations of NKSP (20, 40, 80, 100μg/L) and paclitaxel monotherapy (20, 40, 80, 100μg/L) for 24 h, 48 h and 72 h.. Subsequent experiments were divided into four groups, namely, group A (without any drug treatment), group B (added polypeptide 80μg/L of self-assembled nanoparticles, NKS), group C (80μg/L paclitaxel monotherapy) and group D (80μg/L NKSP). Flow cytometry was used to detect the cell apoptotic rates after 48 h and 72 h treatment in four groups. Western blot assay was used to analyse the protein expressions of bax and caspase-3 after 48 h and 72 h treatment in four groups. Results Both paclitaxel monotherapy and NKSP can inhibit the proliferation of A549 cells. The inhibitory rates of paclitaxel monotherapy group at 48 h and 72 h and NKSP group at 72 h showed an increasing trend in a dose-depen-dent manner (P<0.05). After treatment for 48 hours, the apoptotic rate was significantly higher in D group than that of C group (P<0.05). But the apoptotic rate at 72 h was lower in D group than that of C group (P<0.05). The protein expressions of bax and caspase-3 at 48 h were significantl lower in D group than those of C group, which were higher at 72 h in D group than those of C group (P<0.05). Conclusion Compared to paclitaxel monotherapy group, NKS promotes slow release of pa-clitaxol, which reduces the cytotoxicity and extends the antitumor effects.

Objective To observe the formation of asymmetric dimethylarginine (ADMA)and the expression of dimethylarginine dimethylaminohydrolase 2 (DDAH-2) of human umbilical vein endothelial cells (HUVECs) stimulated by uric acid (UA), and to explore the role of ADMADDAH axis in the vascular endothelial dysfunction induced by uric acid. Methods HUVECs were cultured in M199 medium supplemented with 10% FBS. Cells were exposed to different concentrations of UA (0, 60, 120 mg/L) for 6 h and 24 h. Under different concentrations and times, the level of ADMA in cell suspension was detected by high performance liquid chromatography (HPLC) technique; the gene and protein expressions of DDAH-2 were detected by RT-PCR and Western blotting; the fluorescence intensity of intracellular 2',7'-dichlorofluorescein (DCF) which represented the productions of ROS was detected by the flow cytometry (FCM). The activity of DDAH-2 in HUVCEs which were exposed to different concentrations of UA (0, 60, 120mg/L) or UA (120 mg/L) +NAC (10 mmol/L) for 24 h was estimated by directly measuring the amount of ADMA metabolized by the enzyme and the role of NAC in the activity was studied.Results The expression of ADMA induced by urid acid was dose-depent and higher at 24 h than that at 6 h in the same dosage (all P＜0.05). The dosage and stimulation time of UA did not have any influence on the expression of intracellular DDAH-2 (all P＞0.05). When HUVECs exposed to UA (120 mg/L) for 24 h, the production of intracellular ROS was significantly increased while the activity of DDAH-2 was decreasesd (all P＜0.05) as compared to 60 mg/L stimulation. This effect could be inhibited by the intervention of anti-oxidant NAC. Conclusions The high UA stimulation on HUVECs can increase the expression of intracellular ROS and inhibit the activity of DDAH-2 which increases the concentration of ADMA by decreasing the degradation of ADMA as well as the formation of NO. DDAH-ADMA axis may participate in the vascular endothelial dysfunction induced by UA.
