Sensitivity of supplementation of thyroid hormone on treatment of idiopathic short-stature children during therapy with recombinant human growth hormone.

This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5-3.

Reversal of doxorubicin resistance in breast cancer by mitochondria-targeted pH-responsive micelles.

Chemotherapy is an important approach for clinical cancer treatment. However, the success of chemotherapy is usually hindered by the occurrence of intrinsic or acquired multidrug resistance of cancer cells. Herein, we reported an effective approach to overcome doxorubicin (DOX) resistance in MCF-7/ADR breast cancer using DOX-loaded pH-responsive micelles.

[Increased expression of fatty acid binding protein 4 in lungs of preterm rats after hyperoxic lung injury].

Objective: To study the expression of fatty acid binding protein 4 (FABP4) in lungs and bronchoalveolar lavage fluid (BALF) of preterm rats exposed to 60% O2 and to elucidate the relationship between the changes of FABP4 expression and the pathogenesis of bronchopulmonary dysplasia (BPD).

Methods: Hyperoxic lung injury was induced by exposing to 60% O2 in Spraque-Dawley rats within 6 hours after birth. Rats exposed to air were used as the control group.

Treatment of metastatic breast cancer by combination of chemotherapy and photothermal ablation using doxorubicin-loaded DNA wrapped gold nanorods.

Despite the exciting advances in cancer therapy over past decades, tumor metastasis remains the dominate reason for cancer-related mortality. In present work, DNA-wrapped gold nanorods with doxorubicin (DOX)-loading (GNR@DOX) were developed for treatment of metastatic breast cancer via a combination of chemotherapy and photothermal ablation. The GNR@DOX nanoparticles induced significant temperature elevation and DOX release upon irradiation with near infrared (NIR) light as shown in the test tube studies.
