Objective To observe the clinicopathological characteristics of pulmonary sclerosing hemangioma(PSH) and to analyze its expression and significance in immunohistochemistry,in order to improve the understanding and diagnostic level of this diesease. Methods The clinicopathological features of 6 patients with PSH in Whenzhou Center Hospital from January 2011 to May 2015 were analyzed.Using immunohistochemical methods,the expression of NapsinA,P63, TTF-1,EMA,CK,Vimentin,SP-B,CgA,Syn,CD34 and MC were observed. Results PSH exhibited the following histo-logical features:papillary,solid,hemorrhagic,sclerotic,and mixed.The majority of tumors showed a mixed pattern of histology. The tumor was composed of two distinct cellular components,the cuboidal or surface cells and the round or polygonal or stroma cells.Immunohistochemical staining revealed the both kinds of cells expressed TTF-1 and EMA,the cuboidal cells expressed NapsinA, P63, CK and SP-B,the round or polygonal cells expressed Vimentin.Neither of these two types of cells expressed MC,CD34 and Syn.Sporadic expression of CgA was observed in one case. Conclusion PSH is a rare lung tumor,with various histologie appearance,and often misdiagnosed as lung cancer. The immunohistochemical detection not only suggested that the tumor originates from the multiple potential of the primary respiratory epithelium, but also had important value in the diagnosis and differential diagnosis of PSH.

OBJECTIVETo determine the prevalence of sleep disordered breathing (SDB) in elderly patients with chronic congestive heart failure (CHF) and explore the relations between SDB and left ventricular function.

METHODSBy means of polysomnography, 56 elderly patients with CHF were divided into non-SDB, mild SDB, moderate SDB, and severe SDB groups, and the left ventricular ejection fraction (LVEF) was measure by (99)Tc equilibrium radionuclide angiography.

RESULTSIn the 56 elderly patients with CHF, 38 (67.9%) had SDB, including 12 (21.4%) mild SDB, 14 (25.0%) moderate SDB, and 12 (21.4%) severe SDB patients. Thirty (53.6%) of the 56 patients with CHF had obstructive sleep apnea (OSA), 4 (7.1%) had central sleep apnea and 22 (39.2%) had mixed sleep apnea. The moderate and severe SDB groups had lower minimum arterial oxyhemoglobin saturation during sleep than the non-SDB groups, and the apnea-hyponea index was closely related to LVEF (r=-0.74, P<0.01).

CONCLUSIONThe prevalence of SDB, predominantly OSA, is high in elderly patients with CHF. Moderate and severe SDB might affect the left ventricular function in these patients, who require polysomnography monitoring.
