[Laryngeal reinnervation for unilateral recurrent laryngeal nerve injuries caused by thyroid surgery].

Objective: To explore the protocols and effects of laryngeal reinnervation for unilateral recurrent laryngeal nerve (RLN) injury caused by thyroid surgery.

Methods: Different protocols of laryngeal reinnervation were performed upon 29 patients with unilateral recurrent laryngeal nerve injury caused by thyroid surgery, just coming on to with a course of 2 years, including nerve decompression upon 8 cases, end to end anastomosis of recurrent laryngeal nerve upon 6 cases, and anastomosis of main branch of ansa cervicalis to recurrent laryngeal nerve upon 15 cases. All were been subjected to preoperative and postoperative voice recording, acoustic analysis, videolaryngoscopy, stroboscopy and electromyography.

Biochemistry and genetics of interorganelle aminoglycerophospholipid transport.

The organelle specific reactions that constitute the biosynthetic pathway for aminoglycerophospholipid synthesis provide an important means for examining the biochemistry and genetics of intracellular lipid transport. Biochemical studies with intact and permeabilized cells, and isolated organelles have defined some of the essential features of lipid transport between the endoplasmic reticulum and mitochondria and Golgi/vacuole. Genetic screens have now also identified mutations and genes that are involved in aminoglycerophospholipid traffic between different membranes in mammalian cells, yeast and bacteria.

The myelodysplastic syndromes: analysis of prognostic factors and comparison of prognostic systems in 128 Chinese patients from a single institution.

Introduction: Although retrospective analysis were frequently undertaken, and many prognostic systems for myelodysplastic syndromes (MDS) have been proposed worldwide, few such studies have been performed and the effectiveness of different scoring systems have not yet been verified in independent patient populations in China. The aim of this single center study was to evaluate the prognostic factors and compare the prognostic scoring systems in Chinese patients with MDS.

Materials And Methods: One hundred and twenty-eight patients diagnosed as primary MDS in our Institution were studied retrospectively to identify significant prognostic factors and to assess the predictive value of 11 previously described prognostic systems, including French-American-British (FAB) classification, World Health Organization (WHO) classification, Mufti, Sanz, Morra, Aul, Oguma, Toyama, Morel and international prognostic scoring system (IPSS).

Different RPGR exon ORF15 mutations in Canids provide insights into photoreceptor cell degeneration.

The canine disease, X-linked progressive retinal atrophy (XLPRA), is similar to human RP3, an X-linked form of retinitis pigmentosa, and maps to the same region in the X chromosome. Analysis of the physical map of the XLPRA and RP3 intervals shows a high degree of conservation in terms of genes and their order. We have found different mutations in exon ORF15 of the RPGR gene in two distinct mutant dog strains (XLPRA1, XLPRA2).
