Inhibition of Fap Promotes Cardiac Repair by Stabilizing BNP.

Background: Myocardial infarction (MI) elicits cardiac fibroblast activation and extracellular matrix (ECM) deposition to maintain the structural integrity of the heart. Recent studies demonstrate that Fap (fibroblast activation protein)-a prolyl-specific serine protease-is an important marker of activated cardiac fibroblasts after MI.

Methods: Left ventricle and plasma samples from patients and healthy donors were used to analyze the expression level of FAP and its prognostic value.

Inhibition of fibroblast activation protein ameliorates cartilage matrix degradation and osteoarthritis progression.

Fibroblast activation protein (Fap) is a serine protease that degrades denatured type I collagen, α2-antiplasmin and FGF21. Fap is highly expressed in bone marrow stromal cells and functions as an osteogenic suppressor and can be inhibited by the bone growth factor Osteolectin (Oln). Fap is also expressed in synovial fibroblasts and positively correlated with the severity of rheumatoid arthritis (RA).

Exosome modification to better alleviates endoplasmic reticulum stress induced chondrocyte apoptosis and osteoarthritis.

Osteoarthritis (OA) is characterized by cartilage matrix degeneration and chondrocyte apoptosis. Prolonged endoplasmic reticulum (ER) stress participates in chondrocyte apoptosis and cartilage degeneration in OA progression. miR-486-5p could suppress the apoptosis of nucleus pulposus cells and cardiomyocyte, yet whether miR-486-5p modified exosomes could modulate ER stress and apoptosis of chondrocytes remain unknown.

Baohuoside I Inhibits Osteoclastogenesis and Protects Against Ovariectomy-Induced Bone Loss.

Bone-resorbing osteoclasts are essential for skeletal remodelling, and the hyperactive formation and function of osteoclasts are common in bone metabolic diseases, especially postmenopausal osteoporosis. Therefore, regulating the osteoclast differentiation is a major therapeutic target in osteoporosis treatment. Icariin has shown potential osteoprotective effects.

Synovial mesenchymal stem cell-derived extracellular vesicles containing microRN555A-26a-5p ameliorate cartilage damage of osteoarthritis.

Background: Osteoarthritis (OA) is a degenerative disease characterized by cartilage damage. We aimed to improve the understanding of the protective mechanism of synovial mesenchymal stem cell (SMSC)-derived extracellular vesicles (EVs) in cartilage damage of OA.

Methods: SMSCs and SMSC-EVs were isolated from synovial biopsies of patients without OA and then identified.

Adipose-derived stem cell exosomes facilitate rotator cuff repair by mediating tendon-derived stem cells.

To evaluate the potential capability of adipose-derived stem cell exosomes (ADSC-exos) on rotator cuff repair by mediating the tendon-derived stem cells (TDSCs) and explored the mechanism. First, we investigated the growth, survival and migration of TDSCs in the presence of ADSC-exos . Using a rat rotator cuff injury model to analyze the ability of the ADSC-exos to promote rotator cuff healing .

Preoperative low scores of Life Satisfaction Rating predicts poor outcomes after total knee arthroplasty: a prospective observational study.

Background: Despite the continued improvement in the surgical techniques during primary total knee arthroplasty (TKA), literatures indicate that up to 10 to 20% patients are not satisfied with their outcomes. Psychological factors in this dissatisfaction are yet to be clearly identified. The aim of this study is to develop a method to assess whether the patient's current mental state is suitable enough to accept a TKA surgery.

Using anatomical landmarks to calculate the normal joint line position in Chinese people: an observational study.

Background: Restoring the normal joint line (JL) is an important goal to achieve in total knee arthroplasty (TKA). We intended to study the veracity of several landmarks used to level the normal JL in Chinese people.

Methods: Two hundred fifteen standard CT scans of knee joint were included to measure the distances from landmarks to distal JL (DJL) and posterior JL (PJL), along with femoral width (FW) in order to calculate the ratios.

Bibliometric Analysis of Journals in the Field of Endoscopic Endonasal Surgery for Pituitary Adenomas.

Endoscopic endonasal surgery for pituitary adenomas is being performed more frequently worldwide in the recent years. This first bibliometric analysis was conducted aiming to have a microscopic view of research activities about endoscopic endonasal surgery for pituitary adenomas. The original articles about endoscopic endonasal surgery for pituitary adenomas were extracted from the Web of Science (WoS) and analyzed concerning their distributions.
