Objective To explore the effects of gap junctional(GJ)proteins in pathogenesis of cerebral schistosomiasis, through observing the expression of gap junctional proteins Cx37 mRNA in cultured cerebral arterial endothelium incubated with soluble eggs antigen(SEA). MethodsCerebral artery endothelial cells of rabbits were incubated with SEA, and the experiments were divided into control group and SEA 1 - 5 groups (SEA concentrations were 10.0％ ,5.0％ ,3.3％ ,2.5％,2.0％, respectively), reverse transcription polymerase chain reaction (RT-PCR) and Western blotting were used to examine the expression of Cx37 mRNA and protein in cerebral artery endothelial cells of rabbits, respectively. Results Cx37 mRNA levels of control and SEA 1 - 5 groups were 0.239 ± 0.037, 0.260 ± 0.043, 0.218 ± 0.310, 0.647 ± 0.040, 0.419 ± 0.036, and 0.513 ± 0.038, respectively;SEA 3 - 5 groups were higher than control group of mRNA levels(all P＜ 0.05). Cx37 protein levels of control and SEA 1 - 5 group were 0.401 ± 0.045, 0.485 ± 0.048, 0.749 ± 0.052, 1.119 ± 0.063, 1.015 ± 0.057 and 0.605 ±0.047, respectively, of which SEA 2 - 5 groups were higher than control group(all P ＜ 0.05). ConclusionsExpression levels of Cx37 mRNA and protein in cultured cerebral artery endothelial cells incubated with SEA are higher than those of control cerebral artery endothelial cells, which suggests that the gap junction proteins may play an important role in pathogenesis of cerebral schistosomiasis through SEA and its secretion in infiltration of brain tissue and deposition in the cerebral arteries.

Moderate drought stress has been found to promote the accumulation of active ingredients in Glycyrrhiza uralensis root and hence improve the medicinal quality. In this study, the transcriptomes of 6-month-old moderate drought stressed and control G. uralensis root (the relative water content in soil was 40%-45% and 70%-75%, respectively) were sequenced using Illumina HiSeq 2000. A total of 80,490 490 and 82 588 278 clean reads, 94,828 and 305,100 unigenes with N50 sequence of 1,007 and 1,125 nt were obtained in drought treated and control transcriptome, respectively. Differentially expressed genes analysis revealed that the genes of some cell wall enzymes such as β-xylosidase, legumain and GDP-L-fucose synthase were down-regulated indicating that moderate drought stress might inhibit the primary cell wall degradation and programmed cell death in root cells. The genes of some key enzymes involved in terpenoid and flavonoid biosynthesis were up-regulated by moderate drought stress might be the reason for the enhancement for the active ingredients accumulation in G. uralensis root. The promotion of the biosynthesis and signal transduction of auxin, ethylene and cytokinins by moderate drought stress might enhance the root formation and cell proliferation. The promotion of the biosynthesis and signal transduction of abscisic acid and jasmonic acid by moderate drought stress might enhance the drought stress tolerance in G. uralensis. The inhibition of the biosynthesis and signal transduction of gibberellin and brassinolide by moderate drought stress might retard the shoot growth in G. uralensis.

OBJECTIVETo explore morphological character and clinical significance of superior-posterior acetabular wall by anatomically measuring and quantitatively analyzing thickness of posterior acetabular wall, then provide a theoretical reference for clinical treatment of acetabular fracture.

METHODSFifteen adult formalin-preserved cadaveric pelvises (8 males and 7 females) were used for this investigation. Excess soft tissue was removed and the whole acetabular posterior walls were marked with "angle" sector method and the thickness was measured with caliper in different levels of the different split points. The measurement results were validated and analyzed statistically.

RESULTSAt 5 mm away from acetabular rim, the average thickness of superior-posterior acetablar wall fluctuated between (6.47±0.61) mm and (7.43±0.71) mm; the average thickness of inferior-posterior acetabuluar wall fluctuated between (5.62±0.51) mm and (6.33±0.61) mm; the average thickness of acetabular roof fluctuated between (7.71±0.74) mm and (8.27±0.99) mm. There was no statistical difference between average thickness of superior-posterior wall of acetabulum and inferior-posterior wall of acetabulum (P>0.05), but the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.05). At 10 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (8.81±0.67) mm and (13.35±0.89)mm; the average thickness of inferior-posterior acetabular wall fluctuated between (7.02±0.63) mm and (7.66±0.69) mm; the average thickness of acetabular roof fluctuated between (14.46±0.97) mm and (17.05±1.35) mm. Comparatively, the average thickness of superior-posterior acetabular wall was significantly larger than inferior-posterior wall of acetabulum (P<0.05), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.01). At 15 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (12.08±0.78) mm and (19.84±1.03) mm; the average thickness of inferior-posterior acetabular wall fluctuated between (10.17±0.76) mm and (11.12± 0.77) mm; the average thickness of acetabular roof fluctuated between (23.23±1.12) mm and (26.01±1.53) mm. Comparatively, the average thickness of superior-posterior wall of acetabulum was significantly larger than inferior-posterior acetabular wall (P<0.01), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P< 0.01).

CONCLUSIONThe thickness of entire acetabular posterior edge revealed an increasing tendency from inferior-posterior wall to the superior-posterior wall to acetabular roof. And this trend became more obvious with increasing distance away from acetabular rim. Therefore, the superior-posterior acetabular wall could not only maintain the stability of hip joint but also bear loading.

OBJECTIVETo compare different expression profiles of all known chemokine receptors in human hepatocellular carcinoma (HCC) cell lines with different metastasis potentials.

METHODSEighteen pairs of chemokine receptor primers were designed using Premier software. Expression profiles of the 18 chemokine receptors on four HCC cell lines of lower to higher potentials of metastasis (SMMC-7721, MHCC97-L, MHCC97-H and HCCLM6) were analyzed by RT-PCR. Expression of CXCR4 was detected by RT-PCR.

RESULTSExpression profiles of chemokine receptors on four HCC cell lines with different metastatic potentials had significant differences (P < 0.01), in which CCR10, CXCR4 and CXCR6 expressions decreased gradually as the metastatic potential of the cell lines increased. The expressions of CCR3, CCR4, CCR10, CCR12 and XCR1 on HCCLM6 were significantly reduced compared with SMMC-7721 (P < 0.01), whereas the expressions of CXCR1 (P = 0.006) and CXCR5 (P = 0.003) exceeded that of SMMC-7721. Except for CXCR2, CXCR6 and XCR1, most of chemokine receptors on MHCC97-H were expressed differently compared with MHCC97-L (P < 0.05), in which expressions of CCR1 (P = 0.002), CCR2 (P = 0.004) and CCR5 (P = 0.046) exceeded MHCC97-L. CXCR4 was detected only on the positive controls and SMMC-7721 when the template of total RNA was reduced one-half in RT-PCR.

CONCLUSIONChemokine receptors are expressed very differently at mRNA level on HCC cell lines with different metastatic potentials. The different profiles of chemokine receptors in tumor microenvironment and the function of CXCR4 in HCC should be further studied. Our findings have important implications in understanding the relationship between chemokine receptors and the metastatic potential of HCC.

OBJECTIVETo investigate the inhibition mechanisms of BAY11-7082 (IkappaB-alpha phosphorylation inhibitor) and Lactacystein (proteosome inhibitor) in CD154-induced NF-kappaB activation.

METHODSWe used recombinant CD154 to stimulate EBV/LMP1 negative Ramos B cell and observed the effects of BAY11-7082 and Lactacystein in CD154-induced NF-kappaB luciferase activation, phosphorylation and degradation of IkappaB-alpha, phosphorylation of p65, and nuclear translocation of NF-kappaB subunits upon CD154 stimulation.

RESULTSBoth BAY11-7082 and Lactacystein abrogated CD154-induced NF-kappaB luciferase activation in Ramos cells. While CD154-induced phosphorylation of p65, phosphorylation and degradation of IkappaB-alpha, and nuclear translocation of p50, p65, and c-Rel were all blocked by BAY11-7082; Lactacystein only inhibited degradation of IkappaB-alpha and p65 nuclear translocation.

CONCLUSIONBAY11-7082 and Lactacystein inhibit CD154-induced NF-kappaB activation through different mechanisms.
