RÉSUMÉ

Objective· To compare the impacts on clinical efficiency and safety between 0.014 inch Synchro microwire and Transend microwire used during mechanical thrombectomy for acute ischemic stroke (AIS) caused by large artery occlusion.Methods· Forty-six patients undergoing mechanical thrombectomy with stent retrievers between October 2012 and January 2016 were included,who were classified into Synchro group (21cases) and Transend group (25 cases).The clinical outcome,procedure time,and safety were analyzed and compared between two groups.Results· The recanalization rates were similar between two groups (P=0.600),but time from puncture to vascular recanalization of Synchro group was much shorter than that of Transend goup (48.88 min vs 82.33 min,P=0.001).The rates of functional independence (modified Rankin scale score ≤ 2) were similar between two groups (P=1.000).There was no significant difference of the rates of post-procedure subarachnoid hemorrhage (PSAH) between two groups (P=1.000).However,there were two cases that had fatal subarachnoid hemorrhage with intracranial hematoma in Transend group,while there was only one case of mild subarachnoid hemorrhage who recovered well in Synchro group.Conclusion· Compared with Transend microwire,Synchro microwire can significantly shorten the procedure time of mechanical thrombectomy,and the risk of fatal subarachnoid hemorrhage is rather small.

RÉSUMÉ

A fast, specific, sensitive, convenient, and economical rapid-dot-immunogold staining (R-Dot-IGS) assay was used to detect serum antibodies in patients infected with Schistosoma japonicum. The soluble egg antigen of Schistosoma japonicum was added onto microspore membrane. After pre-reacting and blocking, the serum to be detected and sheep anti-human IgG labeled with chloroauric acid were added sequentially. The assay took 15 minutes. For comparison, the dot-immunogold silver staining (Dot-IGSS) and rapid micro-volume Dot-IGSS (RM-Dot-IGSS) assay were also performed. The positive rate to detect the serum of schistosomiasis japonica by the R-Dot-IGS, Dot-IGSS and RM-Dot-IGSS assay was 98%, 98% and 100%, respectively. Samples from 50 healthy controls, 10 cases of clonorchiasis, and 10 cases of paragonimiasis showed negative reactions except for one case of clonorchiasis with RM-Dot-IGSS assay. Compared with Dot-IGSS and RM-Dot-IGSS, R-Dot-IGS assay has similar sensitivity and specificity, but the latter is quicker, simpler, and cheaper. Therefore, R-Dot-IGS is strongly recommended for rapid diagnosis of schistosomiasis japonica both in epidemiological study and in the clinic.

RÉSUMÉ

By using different blocking and diluting fluids, different developing time and different gold-labeled anti-immunoglobulin (GLA-Ig) which had been preserved in different conditions, the influence on the dot-immunogold-siiver staining (Dot-IGSS) for diagnosis of schis-tosomiasis japonica was studied. The results suggested that using suitable amount of sheep/ bovine serum albumin (BSA) as blocking fluid and calf serum as diluting fluid was a good choice, and 20℃ 20 min was the appropriate time for development. The GLA-Ig without Na3N3 could be preserved in - 20℃ for 2 years if it was not frozen and melted repeatedly.

RÉSUMÉ

Objective To isolate and identify Cryptosporidium oocysts from feces of naturally infected cow. Methods Fecal samples were collected from Cryptosporidium infected cows confirmed by modified acid-fast staining method. Oocysts were isolated and purified with Sheather sucrose density gradient centrifugation technique. Genomic DNA was isolated with Chelex-100. Both primers were designed to amplify Cryptosporidium small subunit ribosome RNA gene (SSU rRNA) and Cryptosporidium oocyst wall protein gene (COWP), respectively. The PCR products were cloned into pGEM-T and pGEM-T Easy vector and sequenced subsequently. Homology and phylogeny were analyzed with BLASTn and MEGA software. Results The results suggested that the size of oocysts was (7.4?0.32)?m by(5.4?0.21)?m and the ratio of length and width was 1.37?0.07 (n=20). BLASTn revealed that the identity of SSU rRNA and COWP gene of Cryptosporidium isolated from cow to the counterparts of C.andersoni was 100% and 99% respectively. Phylogenetic reconstruction placed the isolated Cryptosporidium within the C.andersoni clade based on the sequence of SSU rRNA and COWP gene. Conclusion What isolated from naturally infected cow feces has been identified as C. andersoni.
