Endoscope-assisted styloidectomy via postauricular incision / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility of the endoscope-assisted styloidectomy.</p><p><b>METHODS</b>Sixty patients with Eagle's syndrome undergoing the endoscope-assisted styloidectomy via postauricular incision, including 7 unilateral and 53 bilateral, between June 2010 and March 2013 were reviewed.</p><p><b>RESULTS</b>The styloid processes in all patients were resected successfully via this approach, with the incision length range of 2.0 to 2.5 cm. The mean operative time was (21.3 ± 4.8) min(X(-) ± s), for unilateral surgery and (48.5 ± 11.4) min for bilateral surgery. Fifty-four patients symptom showed complete remission of symptom, 3 cases with decrease in symptom and other 3 cases with no significant relief of symptom after surgery. None case recurred for follow-up of 3 to 70 months. There were 3 sides with ear numbness after surgery for 3 months, and one case had transient facial paralysis and recovered after 3 months.</p><p><b>CONCLUSIONS</b>The endoscope-assisted styloidectomy via postauricular incision is effective and feasible.</p>

The construction of cDNA expression library from the tentacles of Sagartia rosea / 生物工程学报

A cDNA expression library of the tentacles of Sagartia rosea was constructed. The cDNA was cloned into eukaryotical expression plasmid pcDNA3. SMART protocol was used for cDNA library construction and bioinformatics analysis was carried out. 71 novel EST clones were obtained from 130 sequences in the library, of which there were 21 full-length clones, including cytolysin genes, flourescent protein, ubiquinol-cytochrome C reductase gene, elongation factor, ferritin gene riboflavin kinase gene, ribosomal protein. This provides a base for further investigating their biological activity and application.
