Objective To establish a method of detecting the expression of Lysine decarboxylase (LDC) -a key enzyme for the synthesis of alkaloid in the host promoted by the endophytic fungal elicitor of Sophora alopecuroides by using real-time fluorescence quantitative PCR (qRT-PCR). Methods Target gene primers QLDC-F/QLDC-R and reference gene primers Lectin-F/Lectin-R were designed according to LDC and Lectin gene sequences of S. alopecuroids; Five-fold gradient dilution of cDNA was used as the standard sample for the construction of the standard curve of target gene and the reference gene. Reaction system and reaction conditions of qRT-PCR were optimized, and the sensitivity of semi-quantitative PCR and qRT-PCR were analyzed and compared. Under different eliciting time of endophytic fungal elicitors NDZKDF13 of S. alopecuroides, the content of oxymatrine in the host was determined by HPLC, the expression of LDC gene was detected by qRT-PCR, and the relationship between LDC gene expression and the accumulation of OMA was analyzed. Results The results of qRT-PCR were better when the cDNA content in the system was 200 ng/μL and the annealing temperature was 61 ℃. The standard curve of the target gene and the reference gene was constructed, in which the cycle threshold and template concentration showed a good linear relationship, the amplification efficiency was above 99%, and the sensitivity was 25 times that of semi-quantitative PCR. Under the induction effect of endophytic fungal elicitor NDZKDF13, expression of host LDC gene reached the peak on the 6th day, which was 25.58 times that of the control. The increase of OMA content lagged the change of the LDC gene expression and reached the highest amount on the 9th day after the induction. Conclusion The qRT-PCR technique was successfully applied to the functional gene research of S. alopecuroides. Through the optimization of various conditions, a platform for accurate and simple detection of functional gene expression in S. alopecuroides was established.

Objective To investigate the specific anti-tumor immune response induced by dendritic cells (DCs) transfected with total RNA of human pancreatic cancer Capan-2 cells.Methods DCs were isolated and cultured from peripheral blood mononuclear cells (PBMCs) derived from six patients with pancreatic cancer.Total RNA of Capan-2 cells and MUC4 mRNA were transfected into DCs by electroporation.The survival rate of transfected DCs was determined by MTT method and the expression of MUC4 mRNA in DCs was detected by Western blotting.The activity of cytotoxic T lymphocyte cells (CTLs) induced by DCs transfected with total RNA of Capan-2 cells were evaluated by IFN-γ ELISA and the induction of specific CTL response to the killing effect on pancreatic cancer cell in vitro were measured by 51 Cr standard cytotoxicity test.Results The survival rate of DCs transfected with total RNA of Capan-2 cells (DC-Capan-2-total RNA) showed a decrease in a time dependent manner and the survival rate was reduced to 60.81％ after transfection for 96 h.The survival rate of MUC4 mRNA transfection DCs (DC-MUC4 mRNA) was stable at around 80％.The difference of DCs surviral rate between the two groups was statistically significant (P ＜ 0.05).The amount of MUC4 protein expression of DC-Capan-2-total RNA was significantly lower than that of DC-MUC4 mRNA (P ＜0.05).The quantity of CTL IFN-γ release induced by DC-Capan-2-total RNA was (89.34 ± 3.85)U/mL and the quantity of DC-MUC4 mRNA induced CTL IFN-γ release was (21.77 ± 21.77)U/ml There was statistically significant between the two groups (P ＜0.05).In addition,the specific CTLs induced by DC-Capan-2-total RNA could effectively identify and kill the HLA-A2+/MUC4+ Capan-2 and the HLA-A2+/MUC4-PANC 1 cells,and could not effectively identify and kill the HLA-A2 /MUC4-MiaPaCa-2 cells and the HLA-A2-/MUC4 + AsPC-1 cells.Conclusions A more pronounced CTL anti-tumor immune response can be induced by DCs transfected with total RNA of Capan-2 cells compared with a single tumor associated antigen,but it is limited by MHC class Ⅰ antigen presented.

Objective To provide a basis for further study and utilization of the functional gene family of Pht1 in Salviae miltiorrhizae, the Pht1 gene family members from S. miltiorrhizae genome should be explored, identified and functionally predicted. Methods By utilizing the bioinformatics methods, based on the genomic and NCBI database of S. miltiorrhiza, the sequences of Pht1 family candidate genes of S. miltiorrhiza were obtained firstly by screening, and then carried on the multiple sequence alignment, conserved structure lookup as well as phylogenetic tree construction. Finally, the characteristic analysis and biological function prediction were carried out. Results The results showed that 12 Pht1 candidate genes were extracted from the genome of Salvia miltiorrhiza, together with the reported Smpht1, there are 13 Pht1 members in total, their homology as high as 74.34%, and nine members of them could provide more reliable functional annotation. Among the gene family members, Smpht1 & Sm1, Sm4 & Sm6, Sm5 & Sm11, in which these three pairs may share similar function as well as coevolution relation between each other; Smpht1, Sm1, Sm3, Sm5, Sm7, and Sm11, all of the six members can be only expressed in the roots of S. miltiorrhiza. furthermore, except Sm7 induced by p-deficiency and Sm3 member unaffected by the phosphorus supply factor, the other four probably belong to the P-deficiency induced up-regulated expressive genotype, which play an important role in phosphorus absorption of S. miltiorrhiza; Moreover, both Sm7 and Sm16 are possible to expressed in the flower organs of S. miltiorrhiza and then participate in the regulation of phosphorus balance in the flowering stage of plants. In addition, Sm14 is likely to be a mycorrhizal-induced specific expressive gene with the function of phosphorus transfer in Pht1 family members. Conclusion The Pht1 gene family was screened and identified systematically from the genome of S. miltiorrhiza for the first time, in addition, the members with characteristic and biological function were found out, which will provide dependable background support and ideas reference for the further research on the role of Pht1 in the growth and development of S. miltiorrhiza.

Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.
