Dedifferentiated chondrosarcoma: Radiological features, prognostic factors and survival statistics in 23 patients
<div><p>Background</p><p>Dedifferentiated chondrosarcoma is a rare, highly malignant tumor with a poor survival. There are many confusing issues concerning the imaging feature that can facilitate early diagnosis and the factors that might be related to outcomes.</p><p>Methods</p><p>Twenty-three patients with dedifferentiated chondrosarcoma confirmed by pathology were retrospectively reviewed from 2008 to 2015. The patients’ clinical information, images from radiographs (n = 17), CT (n = 19), and MRI (n = 17), histological features, treatment and prognosis were analyzed.</p><p>Results</p><p>There were 12 males and 11 females, and the mean age was 50.39 years old. Fourteen cases affected the axial bone (pelvis, spine), and 9 cases involved the appendicular bone. Seven (41.17%), 9 (47.36), and 12 (66.66%) lesions showed a biphasic nature on radiograph, CT and MRI, respectively. Of the lesions, 17.39% (4/23) were accompanied by pathological fractures. Histologically, the cartilage component was considered histological Grade1 in 12 patients and Grade 2 in 11 patients. The dedifferentiated component showed features of osteosarcoma in 8 cases, malignant fibrous histiocytoma in3 cases, myofibroblastic sarcoma in 1 case and spindle cell sarcoma in 11cases. Twenty-two cases were treated with surgical resection, and 17 cases achieved adequate (wide or radical) surgical margin. In 8 cases, surgery was combined with adjuvant chemotherapy. The overall median survival time was nine months; 17.4% of patients survived to five years.</p><p>Conclusion</p><p>Axial bone location, lung metastasis at diagnosis, inadequate surgical margin, incorrect diagnosis before surgery and pathological fractures was related to poorer outcome. Pre- or postoperative chemotherapy had no definitively effect on improved survival.</p></div
A General Strategy To Fabricate Ni<sub><i>x</i></sub>P as Highly Efficient Cocatalyst via Photoreduction Deposition for Hydrogen Evolution
Presently, precise
deposition of transition metal phosphides at the electron outlet of
photoactive materials as cocatalysts for hydrogen generation is rarely
reported. Demonstrated here is a general photochemical strategy for
the preparation of metal phosphides as cocatalysts for hydrogen generation.
In this work, Ni<sub><i>x</i></sub>P was successfully deposited
on g-C<sub>3</sub>N<sub>4</sub> using nickel sulfate (NiSO<sub>4</sub>) and hypophosphite sodium (NaH<sub>2</sub>PO<sub>2</sub>) as Ni
and P sources, respectively. The Ni<sub><i>x</i></sub>P/g-C<sub>3</sub>N<sub>4</sub> composite exhibits excellent performance of
hydrogen evolution via water splitting (about 8585 μmol g<sup>–1</sup> h<sup>–1</sup> in a triethanolamine aqueous
solution under a 300 W Xe lamp with an AM 1.5G filter). More importantly,
due to the intrinsic acid-resistant properties of Ni<sub><i>x</i></sub>P and g-C<sub>3</sub>N<sub>4</sub>, the Ni<sub><i>x</i></sub>P/g-C<sub>3</sub>N<sub>4</sub> composite demonstrated excellent
acid-stable photocatalytic activity for H<sub>2</sub> evolution (stable
run for 75 h under acidic solution of pH 2). Furthermore, the mechanism
for photocatalytic activity of g-C<sub>3</sub>N<sub>4</sub> enhanced
by Ni<sub><i>x</i></sub>P was investigated in detail by
steady-state photoluminescence spectra and surface photovoltage spectra,
which indicated that separation efficiency of photogenerated carriers
from g-C<sub>3</sub>N<sub>4</sub> was effectively enhanced by Ni<sub><i>x</i></sub>P
