GuiLu-ErXian Glue extract promotes mesenchymal stem cells (MSC)-Induced chondrogenesis via exosomes release and delays aging in the MSC senescence process.

Ethnopharmacological Relevance: The treatment of osteoarthritis (OA) patients is a challenging problem. Mesenchymal stem cells (MSCs) are multipotent cells and play key roles in regenerative medicine for cartilage degeneration. GuiLu-ErXian Glue (GLEXG) is an herbal remedy widely used in traditional Chinese medicine to treat joint pain and disability in elderly OA patients.

Role of estrogen receptors and Src signaling in mechanisms of bone metastasis by estrogen receptor positive breast cancers.

Background/aim: Evidence shows that Luminal A breast cancer is likely to undergo bone metastasis, but the mechanisms involved remain unknown. This study's aim was to demonstrate a correlation between estrogen receptor (ER) positivity and bone metastasis as the clinically preferred site of metastasis, as well as investigating the role of ERα-Src signaling in MCF-7 cells using Snail over-expression as an in vivo bone metastasis model.

Methods: Clinically, the records of breast cancer with distant metastasis were retrospectively reviewed to correlate breast cancer subtypes and preferential metastatic sites.

Characteristics of Intratendinous Microcirculation Shortly After an Achilles Rupture and Subsequent Treatment Outcomes.

Background: Early microcirculatory responses after experimental tenotomy are critical to the healing of tendons and their ultimate tensile strength. The effects of changes in microcirculation on the outcomes of tendon healing, however, have not been determined.

Objectives: To assess microcirculation values in injured Achilles tendons in the first 3 months after surgical repair and to correlate the inter-limb microcirculatory changes with functional outcomes at 3 and 6 months after surgery.

Efficacy of informed versus uninformed physiotherapy on postoperative retear rates of medium-sized and large rotator cuff tears.

Background: It is important to perform the first 12 weeks of rehabilitation without risk of tearing a cuff tendon from its repair site. Our hypothesis was that performing early postoperative rehabilitation with a limitable pendulum exercise device can produce lower retear rate outcomes when it is combined with safe, informed physiotherapy compared with a standardized protocol of rehabilitation performed at home.

Methods: By using an asymmetric arm support brace and an advanced accelerometer, we attempted to determine the benefits of small pendulum exercises (proposed by Long et al).

In vitro and in vivo effects of xanthorrhizol on human breast cancer MCF-7 cells treated with tamoxifen.

This study investigated the herb-drug interaction of xanthorrhizol and tamoxifen in human breast cancer cells. Using MCF-7 cell line as an in vitro model, the herb-drug interaction between xanthorrhizol and tamoxifen was measured by MTT assay, luciferase reporter assay, and cell cycle analysis. The effects of xanthorrhizol on growth/autophagy related signaling were determined by immunostaining, western blotting, and real time RT-PCR.

Screening to Identify Commonly Used Chinese Herbs That Affect ERBB2 and ESR1 Gene Expression Using the Human Breast Cancer MCF-7 Cell Line.

Aim. Our aim the was to screen the commonly used Chinese herbs in order to detect changes in ERBB2 and ESR1 gene expression using MCF-7 cells. Methods.

In Vitro and In Vivo Effects of Jia-Wei-Xiao-Yao-San in Human Breast Cancer MCF-7 Cells Treated With Tamoxifen.

Introduction: There is epidemiological evidence that Jia-Wei-Xiao-Yao-San (JWXYS) is the most common Chinese medicine decoction coprescribed with tamoxifen (Tam) when breast cancer is treated by hormonal therapy. However, whether there is interaction between JWXYS and Tam remains to be clarified. The aim of this study was to investigate the in vitro and in vivo effects of JWXYS on human breast cancer MCF-7 cells treated with Tam.
