Objective To study the effect of Licofelone,a novel non-steroid anti-inflammatory drug,on the expression of Fractalkine induced by interleukin-18(IL-18) in mesangial cells.Methods Rat mesangial cells were cultured and divided into IL-18 stimulated group,Licofelone-treated group and normal control group.The cells in IL-18 stimulated group were stimulated by 10 ?g/L IL-18 for 24 h.In Licofelone-treated group,ahead of exposure of IL-18 for 24 h,cells were treated with Licofelone in the doses of 10,50 and 100 ?mol/L for 30 min.Additionally,the mesangial cells without treatment of IL-18 and Licofelone were used as normal control group.Reverse transcription-polymerase chain reaction(RT-PCR) was used to measure the level of Fractalkine mRNA.The expressions of Fractalkine protein in every group were detected with enzyme linked immunosorbent assay (ELISA).Results In normal control group,the expression level of Fractalkine mRNA was 179.0?21.0.After exposure of IL-18 for 24 h,the level of Fractalkine mRNA was 1 220.1?185.7,which was higher than that in normal control group (t=9.646 P

OBJECTIVETo observe the effect of Guilingji Capsule (GC) on the fertility, liver functions, and serum lactate dehydrogenase (LDH) of adult male SD rats exposed by 900 MHz cell phone.

METHODSTotally 18 adult male SD rats and 36 adult female rats in child-bearing period were selected and randomly divided into three groups according to weight equilibrium principle, i.e., the normal group, the radiated group, and the GC group, 6 males and 12 females in each group. Male rats in the normal group and all female rats were not radiated. Male rats in the radiated group and the GC group received radiation for 4 h per day, lasting for 18 successive days. Rats in the GC group received GC suspension at the daily dose of 0. 15 g/kg by gastrogavage at the same time. Equal volume of normal saline was administrated to other male rats. Then male rats were mated with corresponding female rats from the 14th radiation night to the 18th radiation night in the ratio of 1:2. Male rats were killed following on the next morning of ending the radiation. Female rats were normally fed and then killed before delivery. The pregnant outcomes of female rats in responding groups (the rates of pregnancy and the number of death fetus, birth weight, body length, and tail length) were observed and compared. Serum alanine aminotransferase (ALT), aspartate transferase (AST), AST/ALT, and LDH levels of the male rats were detected by colorimetry. Histological and morphological changes of liver were observed by HE staining.

RESULTSCompared with the normal group, the pregnancy rates of female rats decreased and the number of death fetus increased, the serum LDH level obviously increased in the radiated group (P < 0.05). Serum levels of ALT, AST, and AST/ALT were no significantly changed in the radiated group. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration appeared. Compared with the radiated group, the pregnancy rates increased, the number of death fetus dropped, and the serum level of LDH decreased in the GC group (P < 0.05). There was no obvious change in serum levels of ALT, AST, or AST/ALT. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration were significantly attenuated. The histomorphological structures recovered to normal basically in the GC group.

CONCLUSIONSThe pregnancy rates could be decreased, the number of death fetus increased, histomorphological structures abnormal, and serum LDH level increased by exposure toy GSM 900 MHz cell phone. GC could prevent and treat the aforesaid lesion. But there was no statistical difference in serum ALT or AST levels.

Objective:To investigate the expression of chemokine receptor CXCR4 in hepatocellular carcinoma tissues,hepatocellular carcinoma cell line-MHCC97,human umbilical vein endothelial cells(HUVECs)and the ascites level of CXCL12,ligand of CXCR4,so as to lay a foundation for studying the role of CXCR4 in the metastasis of hepatocellular carcinoma.Methods:The expression of CXCR4 mRNA and protein was examined by RT-PCR and Western blotting in 21 specimens of hepatocellular carcinoma tissues,MHCC97 cells,HUVECs,and 17 specimens of normal hepatic tissues.Meanwhile,the levels of CXCL12 in ascitic fluids were assayed by ELISA in 18 hepatic cancer patients.Results:The relative expression values of CXCR4 mRNA in hepatocellular carcinoma tissues,MHCC97 cells,and HVECs were 2.21?1.09,2.14?1.15 and 1.72?1.20,respectively;and those of CXCR4 protein were 1.51?0.12,1.76?0.25,and 1.89?0.24,respectively;and those of CXCR4 protein were 1.51?0.12,1.76?0.25,and 1.89?0.24,respectively.CXCR4 mRNA and protein were not detected in normal hepatic tissues.ELISA results showed that the 18 hepatocellular carcinoma samples had a CXCL12 concentration range of 783-8 364 pg/ml(median value 6 871 pg/ml)in ascitic fluids.Conclusion:CXCR4 is highly expressed in the hepatocellular carcinoma tissues and cells,which is not associated with the clinical staging of the cancer.The elevated CXCL12 level in the ascitic fluid of cancer patients indicate that CXCR4 may play an important role in the metastasis of hepatocellular carcinoma.

Aiming at molybdate and boron deficient acid purple soil from main peanut cultivated areas in Sichuan,and Mo and B requirement of peanut growth,the feasibility of Co-inoculum of peanut Bradyrhizobium and molybdate and boron was studied.The tolerance to molybdate and boron of the tested strains Spr2-9,Spr4-5 was inspected.The result indicated that the two tested strains could tolerate higher concentration of molybdate than that of boron.The compound inoculum of Bradyrhizobial strain and trace element Mo was developed.The optimum concentration of Mo was 0.4%.

Using universal primer Tyl-copia retrotransposon RT, the conserved reverse transcriptase domain of about 260 bp was amplified by RT-PCR from the Dendrobium officinale which induced by 100 micromol x L(-1) abscisic acid (ABA), indicating these retrotransposons activated by 100 micromol x L(-1) ABA. The amplicons were recovered and cloned,then sequenced and analyzed by related bioinformatics software. Forty-two Ty1-copia like retrotransposon RT transcriptionally activated were obtained with high heterogeneity. The length of these sequences varied from 247 to 266 bp, and was rich in AT and homology ranged from 46.3% to 98.9%. The same to Ty1-copia like retrotransposon RT of genome, different c/s-acting regulatory elements induced by stress conditions and the starting transcription signals, corresponding to CAAT box, TATA box conserved sequences and some other regulatory elements. The c/s-acting regulatory elements induced by stress conditions of reverse transcriptase transcriptionally activated of Tyl-copia retrotransposons were significantly increased than that of Ty1-copia like retrotransposon RT of genome. When being translated into amino acids, fifteen sequences presented stop codon mutation, nineteen sequences presented frameshift mutation, and all sequences presented conserved sequence "SLYGKQ" mutation. Five categories were identified through phylogenic analysis after alignment analyses of their amino acid sequences, and with Ty1-copia like retrotransposon RT of genome having low homology, which indicated that reverse transcriptase transcriptionally activated of Ty1-copia retrotransposons which induced by ABA had Significantly differences with Ty1-copia like retrotransposon RT of genome.
