Clinical Analysis of Severe Radiation Pneumonia.

Objective: The present study aims to discuss the clinical characteristics, factors, and treatment methods affecting the prognosis in patients with severe radiation pneumonia (RP).

Methods: The radiotherapy status, clinical features, imaging characteristics, laboratory examination results, treatment methods, and prognoses of 34 patients with severe RP treated in our department between January 2011 and July 2017 were retrospectively analyzed. The severe RP grading was based on the Common Terminology Criteria for Adverse Events version 4.

Role of infrapatellar fat pad in pathological process of knee osteoarthritis: Future applications in treatment.

It has been found that obese people have a higher proportion in suffering from osteoarthritis (OA), not only in the weight-bearing joints like knee and hip joints, even in non-weight-bearing joints such as hand joints. One of the reasons is because the large amount of adipose tissue secretes some factors, which can promote the occurrence of arthritis. As an important structure of the knee joint, the infrapatellar fat pad (IPFP) is actually a piece of adipose tissue.

Efficacy and Safety of Tranexamic Acid in Intertrochanteric Fractures: A Single-Blind Randomized Controlled Trial.

Objective: To investigate the efficacy and safety of tranexamic acid (TXA) in the reduction of bleeding and the need for transfusion in elderly intertrochanteric fracture patients.

Methods: A total of 100 patients with intertrochanteric fractures undergoing surgery were enrolled and randomly allocated to the TXA group in which patients (75.10 ± 8.

Paeoniflorin inhibits IL-1β-induced MMP secretion via the NF-κB pathway in chondrocytes.

Paeoniflorin serves important cellular roles, exerting anti-cancer, anti-inflammatory and anti-pulmonary fibrosis effects and possesses immune-modulatory properties. However, the exact role of paeoniflorin in the pathogenesis of osteoarthritis (OA) remains unclear. The aim of the present study was to investigate the effects of paeoniflorin on articular surfaces .

Inhibitory Effects of Danshen components on CYP2C8 and CYP2J2.

The use of Chinese herbal medicines and natural products has become increasingly popular in both China and Western societies as an alternative medicine for the treatment of diseases or as a health supplement. Danshen, the dried root of Salvia miltiorrhiza (Fam.Labiatae), which is rich in phenolic acids and tanshinones, is a widely used herbal medicine for the treatment of cardio-cerebrovascular diseases.

Computed tomography angiography and magnetic resonance imaging performance of acute segmental single compartment syndrome following an Achilles tendon repair: A case report and literature review.

Acute compartment syndrome of the lower extremity is a serious postinjury complication that requires emergency treatment. Early diagnosis is of paramount importance for a good outcome. Four muscle compartments in the calf (anterior, lateral, deep posterior, and superficial posterior) may be individually or collectively affected.

A strategy for screening active lead compounds and functional compound combinations from herbal medicines based on pharmacophore filtering and knockout/knockin chromatography.

Screening and deciphering active natural products of herbal medicines are of great importance for modern drug discovery. In this study, a novel strategy was proposed to rapidly filter ineffective compounds and target the most potential leads. The aim is to answer the key question of what components are responsible for the holistic bioactivity of an herbal product.

Expression of vaspin in the joint and the levels in the serum and synovial fluid of patients with osteoarthritis.

The aim of this study was to determine the expression of vaspin in the joint and investigate the distribution between paired serum and synovial fluid (SF) in osteoarthritis (OA) patients, and serum in healthy controls. The gene expression of vaspin was measured by quantitative real-time polymerase chain reaction (qPCR) in the OA joint tissues. The vaspin protein expression in the cartilage, synovium and osteophyte from OA patients who required total knee replacement (TKR) were detected by immunohistochemistry (IHC).

Hinokitiol reduces matrix metalloproteinase expression by inhibiting Wnt/β-Catenin signaling in vitro and in vivo.

Objective: In this study, we investigated the effects of hinokitiol on matrix metalloproteinase (MMP)-1, -3, -13, collagen type II (Col2a1) and β-catenin expressions in rat chondrocytes induced by interleukin-1β and in an experimental rat model induced by intra-articular injection of mono-iodoacetate (MIA) into the knee.

Methods: Chondrocytes were cultured from the articular cartilage of 2-week-old rats. Passaged chondrocytes were pretreated with hinokitiol for 2h followed by co-incubation with IL-1β for 24h.

Visceral adipose tissue-derived serine protease inhibitor inhibits interleukin-1β-induced catabolic and inflammatory responses in murine chondrocytes.

Visceral adipose tissue-derived serine protease inhibitor (vaspin) is a newly identified member of the adipocytokine family, whose precise role in chondrocyte metabolism remains to be elucidated. The aim of the present study was to investigate the effect of vaspin on chondrocytes. The cell viability and the cytotoxicity of vaspin in chondrocytes were examined.

Do we really need closed-suction drainage in total hip arthroplasty? A meta-analysis.

Purpose: The clinical use of closed-suction drainage, which aims to reduce postoperative wound haematomas and infection, is common. This study was performed to determine whether closed-suction drainage is safe and effective in promoting wound healing and reducing blood loss and other complications compared with no-drainage in total hip arthroplasty.

Methods: The literature search was based on PubMed, the Cochrane Library, MEDLINE, and EMBASE.

Sphingosine-1-phosphate: a potential therapeutic target for rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease, which has as its primary target, the synovial tissues and articular cartilage. The current pharmacological treatment of RA includes non-steroidal anti-inflammatory drugs, corticosteroids, and disease-modifying anti-rheumatic drugs. Newer biological agents that work by inactivation of proinflammatory cytokines are available for treatment of RA.
