The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

OBJECTIVETo investigate the relationship between B-type natriuretic peptides (BNP) and subclinical target organ damage in essential hypertensive (EH) patients.
METHODSA total of 317 EH patients were divided into 3 groups according to BNP levels, namely normal (BNP<600 ng/L) group (n=102), moderate (600-883.5 ng/L) group (n=116), and elevated BNP (>883.5 ng/L) group (n=99). The blood pressure, left ventricular mass index (LVMI), the intima media thickness (IMT) of the common carotid artery, the plaque size in the coronary artery (CS) and microalbuminuria levels were analyzed in these patients.
RESULTSThe EH patients with moderate and elevated BNP showed significantly higher LVMI, IMT, CS and microalbuminuria levels than those with normal BNP level (LVMI: 102.8∓23.12 and 123.9∓26.47 vs 91.09∓18.71 g/m2; IMT: 0.95∓0.32 and 1.16∓0.37 vs 0.84∓0.28 mm; microalbuminuria: 31.36∓20.55 and 36.73∓22.07 vs 23.21∓18.68, P<0.01). After adjustment, BNP was positively correlated to LVMI, IMT, CS and microalbuminuria level (r=0.45, 0.43, 0.39 and 0.41, respectively, P<0.01). Multivariate logistic regression analysis showed that age, systolic blood pressure, BNP, FPG, and microalbuminuria, LDL-C, and BMI were all related to the occurrence of subclinical target organ damages.
CONCLUSIONBNP is positively correlated to subclinical target organs damages in EH patients.

OBJECTIVETo explore the feasibility of evaluating complete ischemia-reperfusion injury (IRI) of the testis by contrast-enhanced ultrasonography with microbubbles (MB) targeted to P-selectin (MBp) in rabbits.
METHODSWe randomly divided 30 healthy adult rabbits into five groups of equal number (control, 0.5 h IRI, 1 h IRI, 2 h IRI, and 4 h IRI), prepared phospholipid MB and MBp, and performed contrast-enhanced ultrasonography of the bilateral testes with MB or MBp at an interval of 20 min at different times after IRI. When MB or MBp disappeared completely in the healthy testis at 4 to 5 min after intravenous injection, we recorded the power of the first frame (F-P) in the IRI testes followed by immunohistochemical staining of the testis tissue.
RESULTSCEU with MBp achieved a significantly higher F-P than that with MB in all the IRI groups (P < 0.05), which was (8.34 +/- 1.20) versus (1.87 +/- 0.25) 10(-5) AU at 2 hours, but there was no significant difference between MB and MBp in the control rabbits (0 AU, P > 0.05). Immunohistochemistry showed a significantly time-dependent increase in the expression of P-selectin in the vascular endothelial cells of the IRI testes, but not in those of the control.
CONCLUSIONContrast-enhanced ultrasonography with MBp can be used to evaluate the inflammatory reaction of testicular ischemia-reperfusion injury.

OBJECTIVETo observe the effect of rosuvastatin on left ventricular cardiac function, arteriosclerotic plaque and high sensitive C-reactive protein (hs-CRP) in hypertensive patients with mild elevation of LDL-C.
METHODSSeventy-nine patients with a SBP of 140-179 mmHg and/or a DBP of 90-109 mmHg and mild elevated LDL-C were treated with rosuvastatin for 12 months (n=40) or not (n=39). The changes of hs-CRP, arteriosclerosis plaque and cardiac function at the end of the 12-months treatment relative to the baseline levels were analyzed.
RESULTSAfter 12 months of treatment, LDL-C was decreased by 33.2% in rosuvastatin group but remained unchanged in patients without rosuvastatin treatment. The left ventricular peak filling rate (LVPFR) increased significantly from 1.85 to 2.59 (P<0.05) and the serum levels of hs-CRP reduced significantly (P<0.05) after rosuvastatin treatment. The size of the plaques reduced significantly after a 12-month rosuvastatin therapy.
CONCLUSIONRosuvastatin therapy on the basis of conventional anti-hypertensive drugs can obviously improve the left ventricular diastolic function and produce favorable effects on arteriosclerotic plaques.

Isobaric peptide termini labeling ( IPTL) is a technology which uses light and heavy isotopes to label C-terminus and N-terminus of peptides. As the masses of labeled peptides are equivalent, the complexity of sample is low when analyzing MS data produced by this technology. Besides, paired b and y ions are helpful while analyzing MS/MS data in this kind of experiments. On the basis of this, a novel scoring algorithm, all ions scoring algorithm (AISA), has been designed for IPTL experiments. The information of quantification and qualification can be acquired at the same time using AISA. On Q-Exactive HeLa 2D RPLC dataset, peptide spectrum matches ( PSMs) , distinct peptides and protein groups identified by AISA are 15%, 26%and 22% higher than Morpheus. On human-HCC-HL dataset, PSMs, distinct peptides and protein groups identified by AISA are 24%, 39% and 27% higher than Morpheus. Quantification ratio on Q-Exactive HeLa and human-HCC-HL datasets are 1. 18 and 0. 90, respectively, which are very close to 1. Besides, quantification ratios between 0. 5 and 2. 0 are 91% and 94%, respectively.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.
