catena-Poly[[[diaqua­manganese(II)]-bis­[μ-1,3-bis­(1H-imidazol-1-ylmeth­yl)benzene-κ2 N 3:N 3′]] dinitrate]

In the title compound, {[Mn(C14H14N4)2(H2O)2](NO3)2}n, the MnII ion is located on an inversion center and is coordinated by four N atoms from four 1,3-bis­(1H-imidazol-1-ylmeth­yl)benzene (L) ligands and two water mol­ecules in a distorted octa­hedral geometry. Two L ligands are related by a centre of symmetry and bridge MnII ions, forming a positively charged polymeric chain in [101]. Uncoordinated nitrate anions further link these chains into layers parallel to the ac plane via O—H⋯O hydrogen bonds

Retrospective analysis for thirty-nine patients with solitary fibrous tumor of pleura and review of the literature

<p>Abstract</p> <p>Background</p> <p>Solitary fibrous tumor of the pleura (SFTP) is an uncommon neoplasm arising from mesenchymal cells. The aim of this study is to summarize the experience and the outcome of the surgical treatment for 39 cases of SFTP.</p> <p>Methods</p> <p>From January 2004 to December 2008, 39 patients underwent surgical resection of SFTP in our department. All patients had clinical follow-up by the same team of surgeons. The mean follow-up was 40.3 months.</p> <p>Results</p> <p>A local removal of the neoplasm was accomplished by video-assisted thoracic surgery (VATS) in 9 patients (group A) and by thoracotomy in 30 patients (group B) respectively. Comparing with group B, operations in group A took significantly less operative time, blood loss and spent less time in the intensive care unit and hospital. All specimens were positive for CD34 and Bcl-2. One patient developed recurrence, and the remaining 38 patients are alive and disease free at the end of follow-up.</p> <p>Conclusions</p> <p>Malignant SFTP still had the potential recurrence. VATS represents the more acceptable choice for the selected patients with SFTP.</p
