Abstract
OBJECTIVE To investigate the genetic variations of Toxascaris leonina isolates from different hosts in Jiuquan City, Gansu Province. METHODS The mitochondrial sequences of partial mitochondrial nicotinamide adenine dinucleotide dehydrogenase subunit 1 (pnad1) and pnad5 of eleven T. leonina isolates from domestic dogs, foxes and pet dogs in Jiuquan City, Gansu Province, were amplified using PCR, and the amplification product was sequenced. The genetic variations of pnad1 and pnad5 genes in T. leonina isolates were analyzed. RESULTS The sequences of T. leonina pnad1 and pnad5 genes measured 530 bp and 550 bp in size, respectively. The nucleotide sequence homology was 99.4% to 100.0% for T. leonina pnad1 gene and 99.5% to 99.8% for T. leonina pnad5 gene, and the sequences of T. leonina pnad1 and pnad5 genes shared 99.2% to 99.9% and 99.1% to 99.9% with corresponding sequences of known T. leonina isolates. In addition, there were 19 and 24 polymorphic sites detected in the sequences of T. leonina pnad1 and pnad5 genes, with 10 and 9 haplotypes, haplotype diversity of 0.982 and 0.964 and nucleotide diversity of 0.039 4 and 0.034 2, respectively. Phylogenetic analysis based on pnad1 and pnad5 gene sequences showed that the eleven T. leonina isolates and known T. leonina isolates were clustered into the same branch with a random distribution, which were close to the branch where Toxocara canis was clustered, and far from the branch where other Ascaris species were clustered. CONCLUSIONS There is a minor genetic variation in pnad1 and pnad5 genes of T. leonina isolates from different hosts in Jiuquan City, Gansu Province, and the pnad1 gene is more suitable as a molecular marker than pnad5 gene for analysis of genetic variations in T. leonina.

Abstract
Expression of microRNA(miR)-142-3p has been implicated to be associated with several cancers, whereas its function in bladder cancer (BC) remains unknown. The present study aimed to explore the correlation between the expression of miR-142-3p and the proliferation, migration and invasion of bladder cancer cells by activating Rac1. qRT-PCR was used to measure the expression of miR-142- 3p in bladder cancer tissues and cell lines. RNA transfection was used to silence and accelerate the expression of miR-142-3p in bladder cancer cells. CCK-8 and trans-well assays were used to detect the proliferation, migration and invasion of cells before and after RNA transfection. The direct interaction between Rac1 and miR-142-3p was demonstrated by a dual luciferase reporter assay. qRT-PCR and Western blot assays were used to detect the expression changes in Rac1 before and after transfection. The results showed that miR-142-3p in bladder cancer tissues was significantly lower than that in adjacent tissues and lower than that in HT1376 and T-24 cells but higher than that in T5637 and BIU- 87 cells. Additionally, upregulating miR-142-3p expression not only inhibits the proliferation of SV-HUC-1 and BIU-87 cells but also inhibits migration and invasion, and downregulating miR-142-3p expression showed the opposite results. The expression of Rac1 was promoted after stimulating miR- 142-3p expression, but was inhibited after silencing miR-142-3p expression. In conclusion, miR-142-3p affects the proliferation, migration and invasion of bladder cancer cells by regulating Rac1.

Abstract
Objective: To explore the value of SYNTAX revascularization index (SRI) on evaluating the long-term prognosis of coronary artery disease (CAD) patients implanted with biodegradable polymer drug-eluting stents (BP-DES) and define the best threshold of SRI for predicting all-cause mortality in these patients. Methods: Data used in this study derived from the I-LOVE-IT 2 trial (evaluate safety and effectiveness of the Tivoli DES and the Firebird DES for treatment of coronary). I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, non-inferiority study. A total of 1 829 patients implanted with BP-DES were divided into 3 groups, namely SRI=100% group (n=963), 50%≤SRI<100% group (n=527) and SRI<50% group (n=339). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, myocardial infarction(MI), stroke, and/or any revascularization. The secondary endpoints were components of PoCE and definite/probable stent thrombosis at 48 months. The receiver operating characteristic curve was used to investigate the best cut-off point of SRI for 48-month all-cause mortality. The Cox regression analysis was used to identify independent predictors of the all-cause death and PoCE at 48 months. Results: Incidence of PoCE at 48 months was significantly lower in SRI=100% group than patients with 50%≤SRI<100%(17.34% (167/963) vs. 22.20% (117/527), P<0.05) and SRI<50% (17.34% (167/963) vs. 24.78% (84/339), P<0.05). Comparing with SRI=100% group, the patients with 50%≤SRI<100% suffered higher rates of all MI (7.78% (41/527) vs. 4.26% (41/963), P<0.05) and target vessel MI (6.45% (34/527) vs. 4.26% (41/963), P<0.05); patients with SRI<50% had higher rates of all-cause mortality (5.90% (20/339) vs. 3.12% (30/963), P<0.05) and any revascularization (14.16% (48/339) vs. 3.12% (30/963), P<0.05). The receiver operating characteristic curve analysis showed that the SRI=65% was the best cut-off point to predict the all-cause mortality at 48 months (area under the curve was 0.58, sensitive was 0.47, specificity was 0.70). Meanwhile, SRI<65% was an independent predictor of 48-month all-cause mortality (HR=2.06, 95%CI 1.25-3.38) and PoCE (HR=1.34, 95%CI 1.09-1.66). Conclusions: SRI serves as a good index for predicting long-term prognosis and SRI<65% is an independent predictor of 48-month PoCE and all-cause mortality for CAD patients with BP-DES implantation. Meanwhile, SRI≥65% might be a reasonable threshold of incomplete revascularization.

Abstract
We examined the variation in plasma levels of endothelin (ET), calcitonin gene-related peptide (CGRP), nitric oxide (NO), and malondialdehyde (MDA), as well as superoxide dismutase (SOD) activity, in acute myocardial ischemia reperfusion injury in a rabbit model. Seventy rabbits were randomly assigned into 3 groups. Open-chest surgery (OCS) was performed for all rabbits. Group A (N = 20) received sham-surgery, group B (N = 25) was the reperfusion group, and group C (N = 25) was the infarction group. At 12 h after chest clo-sure, plasma ET levels in groups B and C were clearly increased, while CGRP levels were clearly decreased, particularly in group B. At 24 h after chest closure, ET levels were higher than before OCS, while there was no significant difference between groups B and C. ET in group B was decreased, while that in group C was increased at 12 h. No significant difference in CGRP was observed between 12 and 24 h after chest closure. NO levels in groups B and C at 12 h after chest closure were significantly decreased compared to those before OCS. NO levels in group B at 24, 48, and 72 h were significantly lower than those at 12 h, while those of group C were not significantly changed after 12 h. Dynamic monitoring and comparison of plasma levels of ET, CGRP, NO, and MDA as well as SOD activity revealed that appropriate intervention of these factors may reduce reperfusion injury.

Abstract
A monoclonal antibody was prepared by the hybridoma technology. It reacted only with the protein of Liriomyza trifolii (Burgess) and not with that of Chromatomyia horticola Goureau or Liriomyza sativae Blanchard in indirect enzyme-linked immunosorbent assay. It was effective even after being diluted more than 8.192×10(6)-fold. The detection sensitivity of the antibody was 31.3 µg/ml under controlled conditions. Positive reaction was achieved with all laboratory-reared L. trifolii samples, including larvae, pupae, and adults. An indirect enzyme-linked immunosorbent assay system was successfully established to detect L. trifolii in the field. This antibody was successfully used to determine the L. trifolii collected in different locations, from different host plants, and in different seasons. More than 50% of leafminers collected on Brassica chinensis var chinensis, Apium graveolens (Miller) Persoon, Vigna unguiculata (L.) Walpers, Phaseolus vulgaris L., Lactuca sativa L., and Chrysanthemum coronarium (L.) Cassini ex Spach were L. trifolii, indicating that those six plant species might be the preference host plants of L. trifolii. Population of L. trifolii peaked in September, October, or November in Hangzhou, Zhejiang. These results suggest a great potential of using this McAb for precisely identifying L. trifolii and monitoring the population dynamics of L. trifolii in the field.

Abstract
BACKGROUND The prognosis of patients with intrahepatic cholangiocarcinoma (ICC) is currently unsatisfactory. The aims of this study were to identify prognostic factors after curative ICC resection, and to evaluate the effects of postoperative transcatheter arterial chemoembolisation (TACE). METHODS A retrospective analysis was conducted of 114 ICC patients who underwent curative resection from January 2005 to December 2006. Relationships between survival and clinicopathological factors were evaluated using univariate and multivariate analyses. The benefits of adjuvant TACE were investigated separately. RESULTS The cumulative 1-, 3-, and 5-year survival rates were 63%, 26%, and 15%, respectively. Multivariate analysis revealed that tumour size ≥ 5 cm (hazard ratio [HR] 1.875, 95% CI 1.139-3.088, P=0.013) and advanced TNM stage (stage III or IV) (HR 1.681, 95% CI 1.035-2.732, P=0.036) were independently associated with poor prognosis. Fifty-seven patients underwent adjuvant TACE. In patients with poor prognostic factors, TACE improved the survival rate (P<0.001). However, in patients without poor prognostic factors, TACE did not significantly change the survival rate (P=0.724). CONCLUSIONS Postoperative adjuvant TACE can prolong survival in ICC patients with tumour size ≥ 5 cm or advanced TNM stage.
