Surgical treatment for primary pulmonary lymphoepithelioma-like carcinoma.

Objectives: Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is a rare but unique subtype of non-small-cell lung cancer (NSCLC). Our study aimed to evaluate clinicopathological characteristics and the value of surgical treatment for LELC and explore the relevant prognostic factors in a relatively large cohort.

Methods: We retrospectively reviewed the medical records of 39 lung LELC patients who underwent pulmonary resection with curative intent between January 2009 and December 2013.

Giant liposarcoma of the esophagus: A case report.

Liposarcomas rarely develop in the aerodigestive tract. Here, we present a primary esophageal liposarcoma that was discovered between the T3 and T7 levels of the esophagus during right pleural exploration of a 51-year-old male patient. The patient had presented with non-specific symptoms, including progressive dysphagia over the previous 6 mo, without complaints of chest or epigastric pain, regurgitation, or weight loss.

[Study on chemical compositions and crystallinity changes of bamboo treated with gamma rays].

The structures and qualities of main chemical compositions in cell wall of bamboo treated with gamma rays were tested by nuclear magnetic resonance spectrometer (NMR) and X-ray Diffraction (XRD). The result indicated that the bamboo crystallinity increased at the beginning of irradiation process, while the crystallinity reduced when the irradiation dose was raised to about 100 kGy. During the whole irradiation process, hemicellulose degraded, and with the irradiation doses increased the non-phenolic lignin changed to the phenolic.
