Background Glial cell line derived neurotrophic factor (GDNF) is determined to have a neurotrophy effect and promoting effect to the growth of axon.GDNF has been applied in ophthalmology.Research showed that artemin,a new member of GDNF family,has a better function in protection of neuron,but seldom relevant document of distruibution of artemin in retina is found so far.Objective The aim of the present study is to investigate the distribution and expression of artemin in normal rat retinal neuron cells and retinal ganglion cells,and imitate diabetic environment to observe the expression of artemin at the condition of high glucose.Methods Retinal tissue was isolated from clean neonatal SD rats and cultured by expand culture method in DMEM/F12 containing 10% fetal bovine serum.40 mmol/L of glucose was added in medium in the seventh day after culture for 12 hours as experimental group.The expression and location of artemin in retina were tested by real-time PCR and cell immunofluorescence assay.Use of experimental animals followed the Management Regulation of experimental animals of Jiangsu Province.Results Cultured cells showed the typical cell body and processes in the seventh day.Cultured retinal ganglion cells (RGCs) presented the red fluorescence for Thy1.1 antibody,and multiple fluorescence label revealed that RGCs exhibited the green fluorescence for artemin antibody and red fluorescence for Thy1.1 antibody,indicating artemin protein was positively expressed in cultured RGCs.The numbers of positive cells for Thy1.1 antibody was (442±9)/high field in normal culture group and (263±7) /high field in 40mmol/L glucose culture group,showing a significant difference between them (P<0.05).The expression of artemin mRNA in normal culture group and in 40 mmol/L glucose culture group,was showing a considerably difference between them(P<0.05).Conclusion Artemin can be expressed in cultured retinal neuron cells and RGCs in rats.High glucose environment down-regulate the expression of artemin.This study proved a new idea for protecting RGCs against damage.

High resolution melting (HRM) , an important technology for genotyping and mutation scanning, has broad prospects in the authenticity of traditional Chinese medicine. This paper selected universal CO I primers and used HRM to establish a new method for authenticity of Hairy Antler. PCR was conducted at the annealing temperature of 60 °C and 45 cycles. The range of the DNA template concentration, the primer concentration and the Mg2+ ion concentration were further optimized. The results showed that the Tm values of Cervus nippon were (81.96 ± 0.07), (84.51 ± 0.03) °C and Cervus elaphus was(82.58 ± 0.13), (85.95 ± 0.05) °C with 10-100 mg · L(-1) DNA template, 0.2 µLmol · L(-1) primer, 2.0 mmol · L(-1) Mg2+. This method can authenticate of hairy antler and is simple, fast, high-throughput, visualization.

To simply and rapid authenticate Lonicera japanica. Rapid allele-specific PCR primer was designed base on trnL-trnF 625 G/T Single nucleotide polymorphism and the PCR reaction systems including annealing temperature was optimized; optimized results were performed to authenticate L. japanica and its 9 adulterants. When 100 x SYBR Green I was added in the PCR product of 87 degrees C initial denatured 1 min; 87 degrees C denatured 5 s, 68 degrees C annealing 5 s, 30 cycle; L. japanica visualize strong green fluorescence under 365 nm UV lamp whereas adulterants without. The results indicate rapid allele-specific PCR could authenticate L. japanica and its adulterants rapidly and simply.

Molecular identification of Chinese traditional medicine has come from laboratory research into application, but there are some misunderstandings and problems emerging after rapid development. In this paper, we discuss the usage principle, hot field and technology innovation in molecular identification of Chinese traditional medicine. And molecular identification of traditional Chinese medicine has scientific and objective basis, follows the certain systematic research background, and adopts practical principles to establish case by case multi-class identification system.

Objective To determine the role of erythrocytes immunoadhering in the pathogenesis of the patients with mesangiopro-liferative glomerulonephntis (MsPGN). Methods The immunoadhering functions of erythroeytes and leukoeytcs were measured in 31 patients with no- IgAN,24 patients with IgAN and 30 normal children by rosette tests:RCR,RICR,TRR,TNR and TLR. Results 1. The immunoadhering functions of erythroeytes (RCR and TRR) of the patients with no- IgAN and IgAN were obviously decreased compared to those of control group,but RICR showed no significant difference;2. The immunoadhering functions of leukocytes (TNR and TLR ) of the patients with no- IgAN and IgAN were obviously decreased compared to those of control group;3 The degree of the decreased immunoadhering functions of erythroeytes was correlated respectively with that of the immunoadhering functions of leukoeytes. Conclusions The decrease of the function of erythroeyte and leukocyte immunoadhering plays an important role in the pathogenesis in patients with MsPGN. These rosette tests may be used in clinic.

As a treasure resource of novel drug lead compounds, how to rapidly and high-efficiently screen and isolate active components from natural products is critical. Thanks to its high resolution, high automation and flexible integration, online two-dimensional liquid chromatography has great potential for screening active ingredients from complex matrices by integrating a highly specific bio-recognition process into a two-dimensional liquid chromatography system before, on or after the column separation. This review comprehensively summarized recent developments, applications and shortcomings of online two-dimensional liquid chromatography for natural product screening from different integration modes, including pre-column, on-column and post-column screening methods.
