Propylenella binzhouense gen. nov., sp. nov. isolated from activated sludge, and proposal of Propylenellaceae fam. nov.

A Gram-stain-negative, non-spore-forming, non-motile, short-rod-shaped, and aerobic bacterial strain (designated L72) was isolated from propylene oxide saponification wastewater activated sludge obtained from a wastewater treatment facility in Binzhou (Shandong Province, PR China). Strain L72 grew between 25 and 40 °C (optimum growth at 30 °C). The pH range for growth was between 6.

[Association between lymphangiogenesis and clinicopathological features and prognosis in laryngeal carcinoma].

Objective: To detect lymphangiogenesis by labeling the lymphatic endothelial marker, lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1), and study the prognostic relevance of lymphangiogenesis in laryngeal squamous carcinoma.

Methods: Clinical files and specimens of 78 patients with histologically diagnosed laryngeal carcinoma were stained with LYVE-1 as a specific lymphatic endothelial marker. The lymphatic vessel density (LVD) was measured, and the correlation between LVD and clinicopathological features of the tumor cases was analyzed.

[Vocal fold augmentation by injection of autologous fascia and fat].

Objective: To evaluate the effect of combination of autologous fascia and fat injection into vocal fold for the treatment of patients with unilateral vocal fold paralysis and to observe the long-term effectiveness of this procedure.

Methods: A total of 26 unilateral vocal fold paralysis patients underwent vocal fold injection under general anesthesia, meanwhile, the mucosa of the injected point was sutured through laryngoscope under direct vision. There were 6 patients underwent autologous fat injection into vocal fold (group A), and 20 patients underwent autologous anterior rectus sheath fascia and fat injection (group B).

[Tubed pectoralis major myocutaneous flap for reconstruction of circumference pharyngoesophageal defects].

Objective: To investigate the feasibility and efficacy of tubed pectoralis major myocutaneous flap in the reconstruction of circumferential defects following resection for locally advanced hypopharyngeal and cervical esophageal carcinoma.

Methods: From Dec. 2004 to Oct.
