Novel recombinant human thyroid-stimulating hormone in aiding postoperative assessment of patients with differentiated thyroid cancer-phase I/II study.

Purpose: Thyroid hormone withdrawal (THW) inevitably induced hypothyroidism in patients with differentiated thyroid cancer (DTC), and we aimed to evaluate the safety and efficacy of a novel recombinant human thyroid-stimulating hormone (rhTSH, ZGrhTSH) as an alternative of THW in China.

Methods: Totally, 64 DTC patients were enrolled with 24 in the dose-escalation cohort equally grouped into 0.9 mg × 1 day, 0.

[Effects of long-term nitrogen addition on the nitrogen pools in a meadow steppe ecosystem].

Increasing atmospheric nitrogen (N) deposition greatly affects species diversity, productivity, and stability of ecosystems. It is thus of the great importance to understand how grassland N pools respond to the increased atmospheric N deposition. This study was conducted in a meadow steppe in Erguna, Inner Mongolia, China.

Induction of p53 expression and apoptosis by a recombinant dual-target MDM2/MDMX inhibitory protein in wild-type p53 breast cancer cells.

The tumor suppressor gene p53 is often inactivated in breast cancer cells due to gene mutation or overexpression of its repressors (such as murine double minute 2 and murine double minute X). Inhibitors of murine double minute 2 (MDM2) and murine double minute X (MDMX) could lead to tumor suppression by restoration of p53 activity and such an approach is a promising strategy for future control of breast cancer. This study aimed to investigate the feasibility of the recombinant MDM2 and MDMX inhibitory protein in control of breast cancer in vitro.

[Expression and clinical significance of vascular endothelial growth factor-C and nm23-H1 in stage II and III colorectal carcinomas].

Objective: To discuss the expression and clinical significance of VEGF-C and nm23-H1 in stage II and III colorectal carcinomas.

Methods: SP immunohistochemical staining was employed to determine the expression of vascular endothelial growth factor-C (VEGF-C) and nm23-H1 in the tumor tissues of 110 cases of stage II and III colorectal carcinomas and in the adjacent mucosal tissues of 53 cases as control, and analyze their correlation with cliniopathological features and prognosis.

Results: The positive expression of VEGF-C in the carcinoma tissues was 71.
