Characterization and In vitro Release & In vivo Behavior Study of Self-Assembled Nano-Emulsion in XiaoYao Pill for Enhanced Drug Delivery.

Background: Traditional Chinese medicine formulations often contain hydrophobic components with limited solubility and stability, leading to low oral bioavailability. Self-assembled nanoparticles (SANs) have shown promise in enhancing oral bioavailability of these components. However, whether un-decocted Chinese herbal pellets can generate SANs and the impact of SANs formed by multiple components on pharmacokinetic parameters remains unexplored.

The emerging role of exosomes in the development of testicular.

The mechanisms of testicular development in mammals are complex. Testis is an organ that produces sperm and secretes androgens. It is rich in exosomes and cytokines that mediate signal transduction between tubule germ cells and distal cells, promoting testicular development and spermatogenesis.

Liver X receptors agonist T0901317 exerts ferroptosis sensitization in cancer.

Numerous studies have confirmed the anticancer effects of ferroptosis on a wide range of tumors, specifically in providing new perspectives for tackling drug resistance and treating refractory tumors. Notably, mechanisms of improving tumor susceptibility to ferroptosis have been a focus of current research. This study discovered that co-treatment of LXRS agonist T0901317 and ferroptosis inducers (FINs) significantly inhibited the proliferation of cancer cells, this inhibition effect could be reversed by specific inhibitors of ferroptosis and accompanied by elevated lipid peroxides.

Redox-dependent modulation of metformin contributes to enhanced sensitivity of esophageal squamous cell carcinoma to cisplatin.

Glutathione is the major intracellular anti-oxidant against reactive oxygen species and serves as a detoxification essential. The anti-diabetic drug metformin has been showed to exert anti-tumor activity via modulation of redox homeostasis. In this study, we provided evidence that metformin inhibits proliferation and induces apoptosis of esophageal squamous cancer cells.

Radiosensitivity enhancement of human hepatocellular carcinoma cell line SMMC-7721 by sorafenib through the MEK/ERK signal pathway.

Purpose: Sorafenib, an oral multikinase inhibitor, is the first agent that has demonstrated an improved overall survival benefit in advanced hepatocellular carcinoma, setting a new standard for first-line treatment. However, the association between radiosensitivity and sorafenib remains unclear. The purpose of this study was to investigate whether sorafenib could enhance radiosensitivity and the possible mechanisms of sorafenib-mediated radiosensitization in human hepatocellular carcinoma cell line SMMC-7721.

Hypoxia-induced autophagy confers resistance of breast cancer cells to ionizing radiation.

Hypoxia is a hallmark of solid tumors, which presents a major obstacle to the effectiveness of radiation therapy. However, the function and the importance of molecular response have not been well defined. In the present study, hypoxia-induced autophagy and its effect on the response of breast cancer cells to ionizing radiation were examined.

[Value of recombinant human thrombopoietin in the treatment of chemotherapy-induced thrombocytopenia in patients with solid tumor].

Objective: To evaluate the efficacy and safety of domestically manufactured recombinant human thrombopoietin (rhTPO) in the treatment for chemotherapy-induced thrombocytopenia in patients with solid tumors.

Methods: A non-randomized controlled study was conducted. Seventy-two patients with platelet count < 75 x 10(9)/L after chemotherapy were enrolled into this study according to the standard criteria of NCI-CTC toxicity stratification.

[Study on the controlling effect of Shenqi Fuzheng injection on plasma cytokine network in patients with thoracic tumor undergoing radiotherapy].

Objective: To investigate the effect of Shenqi Fuzheng Injection (SFI) in radiation pneumonitis and its influence on the levels of plasma transforming growth factor beta (TGF-beta), tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) at various stages (pre-, mid- and post-radiation) of radiotherapy (RT).

Methods: Fifty-eight patients enrolled in this study were randomized into two groups, all received conventional radio therapy, but the treatment group was intravenously dripped with SFI additionally, once daily, starting 3 days before radiotherapy to 1 week after the end of it. Levels of TGF-beta, TNF-alpha and IL-10 in blood samples collected and frozen at different time point of RT, before radiotherapy (Pre-RT), after received 40-50 Gy radiation (Mid-RT) and in time of terminating RT (Post-RT), were measured with enzyme linked immunosorbent assay (ELISA).
