To establish a molecular identification method for Bletillae Rhizoma, this paper extracted genome DNA from Bletillae Rhizoma and its adulterants. The sequences of rDNA ITS2 were sequenced after amplifying. Then multiple alignments of ITS2 were constructed phylogenetic tree with Neighbor Joining by MEGA 5. 1 and found out SNPs loci. The result showed that rDNA ITS2 region could identify Bletillae Rhizoma and its adulterants. There existed the SNPs loci, which could identify Bletilla striata and B. ochracea. Furthermore, we designed specific primers against the SNPs loci of B. striata and B. ochracea, then screened primers and optimized the PCR amplification conditions. Finally, the DNA of B. striata and B. ochracea were specifically amplified by BJ59-412F, BJ59-412R and HHBJ-225R. The length of amplification products were respectively about 350 bp and 520 bp that were effectively identified of B. striata and B. ochracea. While, the adulterants of Bletillae Rhizoma were no-reaction occurring. To sum up, the amplification conditions of the primers can identify B. striata, B. ochracea and their adulterants successfully at the same time. This method was easy, time-saving, and reliable, which can be used as a rapid method for molecular identification of Bletillae Rhizoma.

In order to breed and spread a new cultivar of Curcuma wenyujin, the C. wenyujin germplasm resources were investigated in authentic regions. Better varieties were chosen by comparing the yield, economic characters and quality differences between different cultivars. The results showed that the character of new selected cultivar was stable, the yield of zedoary, turmeric and curcuma was reached 313.7, 177.9, 91.2 kg per 667 m2, respectively, it increased 11.6%, 10.2%, 14.2% comparing with farmer varieties. The volatile oil contents in zedoary and turmeric was 4.0%, 3.0%, respectively. The target ingredients (germacrone) content was stable. It is demonstrated that the new cultivar "Wenyujin No. 1" has value for extension at authentic regions.

Objective: To study the chemical constituents of Bletilla striata (Thunb. ) Reichb. f. Methods: The con-stituents were separated and purified by column chromatography with silica gel and Sephadex LH-20,and were identified byspectral analysis. Results: Five compounds were identified as: 2, 7-dihydroxy-4-methoxy-9, 10-dihydrophenanthrene (1), 2, 7-dihydroxy-3, 4-dimethoxyphenanthrene (2), 3, 7-dihydroxy-2, 4-dimethoxyphenanthrene (3 ), 3', 3--dihydroxy--5-methoxybiben-zyl(4), p-hydroxybenzaldehyde (5), Conclusion: Compound 2, 3, 4 are isolated from this plant for the first time.

A sandwich format immunochromatographic assay for detecting foot-and-mouth disease virus (FMDV) serotypes was developed. In this rapid test, affinity purified polyclonal antibodies from Guinea pigs which were immunized with sucking-mouse adapted FMD virus (A/AV88(L) strain) were conjugated to colloidal gold beads and used as the capture antibody, and affinity purified polyclonal antibodies from rabbits which were immunized with cell-culture adapted FMD virus (A/CHA/09 strain) were used as detector antibody. On the nitrocellulose membrane of the immunochromatographic strip, the capture antibody was laid on a sample pad, the detector antibody was printed at the test line(T) and goat anti-guinea pigs IgG antibodies were immobilized to the control line(C). The lower detection limit of the test for a FMDV 146S antigen is 11.7ng/ml as determined in serial tests after the strip device was assembled and the assay condition optimization. No cross reactions were found with FMDV serotype C, Swine vesicular disease (SVD), Vesicular stomatiti svirus (VSV) and vesicular exanthema of swine virus (VES) viral antigens with this rapid test. Clinically, the diagnostic sensitivity of this test for FMDV serotypes A was 88.7% which is as same as an indirect-sandwich ELISA. The specificity of this strip test was 98.2% and is comparable to the 98.7% obtained with indirect-sandwich ELISA. This rapid strip test is simple, easy and fast for clinical testing on field sites;no special instruments and skills are required, and the result can be obtained within 15 min. To our knowledge, this is the first rapid immunochromatogarpic assay for serotype A of FMDV.

ObjectiveTo investigate the expression of programmed death receptor ligand 1 ( PD-L1 ) of peripheral blood mononuclear cells (PBMCs) in patients with hepatic cystic echincccccosis (HCE) and its relation with interferon-γ.MethodsThe clinical data of 63 patients with HCE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from June 2010 to February 2011 were retrospectively analyzed.All patients were divided into HCE active group (38 patients) and HCE non-active group (25 patients) according to the system established by the World Health Organization's Informal Working Group on Echinocoecosis.Twenty patients with hepatic hemangioma or healthy individuals were recruited in normal control group.The positive rate of PD-L1 expression was detected by flow cytometry and immunocytochemistry.The expression of interferon-γ was detected by enzyme-linked immtmosorbent assay (ELISA).All data were analyzed by the t test,one-way analysis of variance,LSD test and chi-square test.The relationship between the expression of interferon-γ and positive rate of PD-L1 expression was analyzed by the Pearson test.ResultsThe results of flow cytometry showed that the positive rates of PD-L1 expression in the HCE active group,HCE non-active group and normal control group were 12.1％±3.8％,10.9％ ± 2.5％ and 9.1％ ±2.5％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =3.327,P ＜ 0.05 ).The results of immunohistochemistry showed that the positive rates of PD-LI expression in the HCE active group,HCE non-active group and normal control group were 11.9％ ± 3.4％,i0.6％ ± 2.9％ and 9.5％ ± 3.6％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =2.470,P ＜ 0.05 ).The expressions of intefferon-γ in the HCE active group,HCE non-active group and normal control group were ( 141 ± 38 ) μμg/L,( 124 ± 32 ) μg/L and ( 105 ± 42 ) μg/L.There wasasignificant difference in the expression of interferon-γ between the HCE active group and normal control group ( t =3.280,P ＜ 0.05).The results of flow cytometry and immunohistochemistry revealed that the positive rate of PD-L1 expression was positively correlated with the expression of interferon-γ( r =0.59,0.61,P ＜ 0.05 ).Conclusion With the help of interferon-γ,PD-L1 may play an important role in promoting the immune.evasion of echinococcus.

Objective Toanalyzetheclinicalcharacteristicsandtreatmentoutcomesofspinalfilum terminalevascularmalformation.Methods Theclinicaldataof6patientswithfilumterminalevascular malformation diagnosed and treated from January 2008 to December. 2013 were analyzed retrospectively. The definition of filum terminale vascular malformation is anterior/posterior spinal artery feeding arteriovenous fistula or arteriovenous malformation and located below conus medullaris,and does not complicate with spinal vascular lesions in the other part. The Aminoff & Logue score and MRI of spinal cord function were performedatoneyearaftermicroneurosurgeryand/orendovascularembolization.Results Allpatients were males. Their clinical presentations were the weakness of both lower extremities and sphincter disturbance. The mean course of disease was 17. 1 ± 5. 2 months. The pathological type of the 6 patients were all arteriovenous fistulas. The feeding arteries included lumbar artery,internal iliac artery,and median sacral artery. Two of the 6 patients underwent Onyx glue embolization,3 were treated with microneurosurgery,and 1 was treated with embolization in combination with microneurosurgery. They were all achieved anatomic cure. The Aminoff & Logue scores were improved after 1 year (3. 8 ± 1. 9 scores before procedure,2. 8 ± 2. 0 scores after procedure),there was no significant difference (P >0. 05). The myodynamia scores were improved in 3 patients,2 did not change,1 got worse. The urinary and bowel functions were improved in 2 patients,and4didnotchange.Conclusion Filumterminalevascularmalformationisararevascular malformation of spinal cord. Both embolization and surgical treatment can achieve anatomic cure. Although the spinal cord function can be only partially restored,but continuous deterioration can be prevented.
