Application of MMP-2-responsive forming injectable hydrogel in preventing the recurrence of oral squamous cell carcinoma.

Oral squamous cell carcinoma is one of the most common types of cancer. Surgical resection is one of the most important treatments at present. However, patients often suffer from regional recurrence after surgery.

Why is glycocholic acid sodium salt better than deoxycholic acid sodium salt for the preparation of mixed micelle injections?

Classical mixed micelle systems make excellent parenteral drug carriers for lipophilic or poorly soluble drugs, but many formulations details are not fully understood and need further study. Thus, we constructed mixed micelle systems with lecithin and either glycocholic acid sodium salt or deoxycholic acid sodium salt in order to investigate the differences between the bile salts. Vitamin K, a lipid-soluble drug, was encapsulated in the mixed micelles, and the influence of bile salts on the quality and stability of the mixed micelle systems was analyzed.

miR-27a protects against acute lung injury in LPS-treated mice by inhibiting NF-κB-mediated inflammatory response.

Acute lung injury (ALI), which is an excessive uncontrolled inflammatory response in the lung, is mediated by several pro-inflammatory mediators. Recent evidence has implicated microRNAs (miRNAs) in regulation of inflammation in different diseases. However, the roles and underlying molecular mechanism of miRNAs in ALI have not been adequately elucidated.

Circular RNA expression profiles in synovial fluid: a promising new class of diagnostic biomarkers for osteoarthritis.

Background: Previous studies suggest that circRNAs abnormally function in the progression of osteoarthritis (OA). However, little is known about the diagnostic value of circRNAs in patients with OA. To assess potential applications of circRNAs as diagnostic tools in OA, expression profiles of circRNAs in synovial fluid from OA patients and healthy subjects were obtained.

Correlation between bone mineral density and serum trace element contents of elderly males in Beijing urban area.

Trace element levels are associated with the incidence of osteoporotic fractures, but related mechanisms remain unknown. Trace elements may interfere with growth, development and maintenance of bones. Therefore, we investigated whether plasma trace element levels are associated with bone mineral density in elderly males in Beijing.
