Bioinformatic and functional analysis of OsDHN2 under cadmium stress.

As a toxic heavy metal, cadmium (Cd) is one of the principal pollutants influencing rice productivity and food security. Despite several studies, the underlying mechanism of Cd response in plants remains largely unclear. Dehydrins are part of the late embryogenesis abundant (LEA) family which protect plants against abiotic stresses.

Status and prospects of the application of root exudates in the restoration of polluted or desertated soil.

Ecological and environmental problems including heavy metal pollution have received increasing concerns. Given the shortage of physical and chemical remediation methods in high cost and secondary pollution, using plants and microorganisms for joint remediation of environment has become one of the most important strategies. Root exudates are an important medium for information and nutrient exchange between plants and soil.

[Surgical treatment for long bone giant cell tumor of extremity with pathologic fracture].

Objective: To identify the clinical features of patients with giant cell tumors (GCT) of long bones in extremities presented with pathological fracture (PF), and discuss the surgical strategy with retrospective analysis and literature review.

Methods: We searched medical electronic records from January 1999 to December 2011 in our hospital to identify patients with definite diagnosis of extremity GCT presented with PF. Clinical data including gender, tumor site, age, surgical treatment option, postoperative complication, limb function, local recurrence and pulmonary metastasis were collected and analyzed statistically.

[Evaluation of prognostic factors for synovial sarcoma].

Objective: To determine the independent prognostic factors of primary synovial sarcoma.

Methods: The clinical data of 52 patients followed up from 66 patients with synovial sarcoma treated between September 1997 and September 2008 was analyzed retrospectively. There were 28 male and 24 female patients aged from 11 to 71 years old.
