Nuciferine ameliorates osteoarthritis: An in vitro and in vivo study.

Osteoarthritis (OA) is the most common musculoskeletal disease and a leading cause of pain and disability. A key hallmark of OA is cartilage degradation, which occurs due to an imbalance between the synthesis and degradation of the extracellular matrix (ECM). Interleukin-1β(IL-1β) has been reported to regulate ECM metabolism.

Bergamottin (Ber) ameliorates the progression of osteoarthritis via the Sirt1/NF-κB pathway.

Osteoarthritis (OA) is a common chronic disease characterized by progressive cartilage degeneration and secondary synovial inflammation. Bergamottin (Ber) is an important natural derivative of the furanocoumarin compound, extracted from natural foods, such as the pulp of grapefruits and pomelos. Ber exhibits several characteristicsthat are beneficial to human health, such as anti-inflammation, antioxidant, and anti-cancer effects.

Intraoperative pain prediction of percutaneous kyphoplasty under local anesthesia by preoperative experimental pain assessment.

Background: Percutaneous kyphoplasty (PKP) is the preferred treatment for osteoporotic vertebral compression fractures (OVCF) Currently, the preoperative anesthesia methods for PKP are mainly local anesthesia and tracheal intubation general anesthesia.

Objective: To assess whether patient sensitivity to pain measured preoperatively could predict the patients' pain response during PKP treatment under local anesthesia, to facilitate the development of an optimal preoperative anesthesia plan for patients.

Methods: Fifty-five female patients diagnosed with osteoporotic single vertebral fracture who were treated with PKP under local anesthesia were selected.

Comparison of unipedicular and bipedicular kyphoplasty for treating acute osteoporotic vertebral compression fractures in the lower lumbar spine: a retrospective study.

Background: Unipedicular and bipedicular approaches for percutaneous kyphoplasty are reportedly both effective in treating osteoporotic vertebral compression fractures (OVCFs). However, most studies have reported thoracolumbar fractures, with few reports describing the treatment of the lower lumbar spine. Here, we compared the clinical and radiological results of unipedicular and bipedicular approaches for percutaneous kyphoplasty for treating osteoporotic vertebral compression fractures.

Procyanidin B2 regulates the Sirt1/Nrf2 signaling pathway to improve random-pattern skin flap survival.

Random-pattern skin flaps have been widely used in the reconstruction of damaged tissues. Ischemia-reperfusion injury occurring in the distal regions of the flap is a common issue, which often leads to flap necrosis and restricts its clinical applications. Procyanidin B2 (PB2), a naturally occurring flavonoid in large quantities in various fruits, has been demonstrated to exhibit several significant pharmacological properties.

Percutaneous mesh-container-plasty versus percutaneous kyphoplasty for the treatment of Kümmell's disease: a retrospective cohort study.

Background: Both percutaneous kyphoplasty (PKP) and percutaneous mesh-container-plasty (PMCP) were important procedures for the treatment of Kümmell's disease. This study aimed to compare the clinical and radiological results of PKP and PMCP for the treatment of Kümmell's disease.

Methods: This study included patients with Kümmell's disease treated at our center between January 2016 and December 2019.

Sitagliptin attenuates neuronal apoptosis via inhibiting the endoplasmic reticulum stress after acute spinal cord injury.

Regulation of endoplasmic reticulum stress (ER) stress-induced apoptosis and nerve regeneration is a hopeful way for acute spinal cord injury (SCI). Sitagliptin (Sita) is one of dipeptidyl peptidase-4 (DPP-4) inhibitor, which is beneficial neurons damaged diseases. However, its protective mechanisms of avoiding nerve injury remain unclear.

Percutaneous mesh-container-plasty versus percutaneous kyphoplasty in the treatment of malignant thoracolumbar compression fractures: a retrospective cohort study.

Objective: This study aimed to compare the clinical and radiological results of percutaneous mesh-container-plasty versus percutaneous kyphoplasty in the treatment of malignant thoracolumbar compression fractures.

Methods: Patients with malignant thoracolumbar compression fractures treated in a single tertiary care center between January 2011 and December 2020 were retrospectively reviewed and included in the study. Ninety-four patients who were diagnosed by pathological biopsy were divided into 2 groups according to the type of surgical treatment: the percutaneous kyphoplasty group (50 patients: 24 male, 26 female; mean age=73.

[Analysis of the effect of double button plate combined with strengthened anchor in the treatment of acromioclavicular dislocation].

Objective: To evaluate the efficacy and prognosis of double button plate combined with strengthened anchor technique and clavicular hook plate internal fixation for complete acromioclavicular joint dislocation.

Methods: From July 2017 to September 2020, a total of 42 patients with acromioclavicular joint dislocation treated by surgery were choosen as study objects and divided into observation group (21 cases) and control group (21 cases). In the observation group, there were 14 males and 7 females, aged 21 to 63 years old, with an average of (45.

Analysis of Related Influencing Factors of Deep Vein Thrombosis after Lumbar Internal Fixation and Treatment Strategy.

Lumbar internal fixation is a traditional surgical method for the treatment of degenerative diseases of the lumbar spine. However, due to its large surgical trauma, it easily causes complications such as deep venous thrombosis (DVT) after the operation. DVT refers to the abnormal coagulation of blood in deep veins, blocking the lumen, causing venous blood return disorder, causing venous blood return disorder to cause swelling and pain, which affects the recovery of the patient's lumbar spine function.

Safety and efficacy studies of kyphoplasty, mesh-container-plasty, and pedicle screw fixation plus vertebroplasty for thoracolumbar osteoporotic vertebral burst fractures.

Background: Percutaneous kyphoplasty (PKP), percutaneous mesh-container-plasty (PMCP), and pedicle screw fixation plus vertebroplasty (PSFV) were three methods for osteoporotic vertebral burst fractures (OVBF). The purpose of the current study was to evaluate the clinical safety and efficacy of PKP, PMCP, and PSFV for OVBFs.

Methods: This retrospective study included 338 consecutive patients with thoracolumbar OVBFs who underwent PKP (n = 111), PMCP (n = 109), or PSFV (n = 118) and compared their epidemiological data, surgical outcomes, and clinical and radiological features.

Critical roles of sphingosine kinase 1 in the regulation of neuroinflammation and neuronal injury after spinal cord injury.

Background: The pathological process of traumatic spinal cord injury (SCI) involves excessive activation of microglia leading to the overproduction of proinflammatory cytokines and causing neuronal injury. Sphingosine kinase 1 (Sphk1), a key enzyme responsible for phosphorylating sphingosine into sphingosine-1-phosphate (S1P), plays an important role in mediating inflammation, cell proliferation, survival, and immunity.

Methods: We aim to investigate the mechanism and pathway of the Sphk1-mediated neuroinflammatory response in a rodent model of SCI.

[Effects of tranexamic acid combined with temporary drain clamping on postoperative blood loss in total knee arthroplasty].

Objective: To evaluate the efficacy and safety of one dose tranexamic acid combined with temporary drain lamping in primary unilateral total knee arthroplasty.

Methods: Total 160 patients undergoing unilateral primary total knee arthroplasty between January 2012 and December 2013 were randomly divided into four groups(40 cases in each group):group A (the drain was clamped for 2 hours after the operation and the patients received 20 ml physiological saline), group B(the drain was clamped for 2 hours after the operation and the patients received 10 ml tranexamic acid and 10 ml physiological saline), group C (the drain was clamped for 4 hours after the operation and the patients received 20 ml physiological saline) and group D(the drain was clamped for 4 hours after the operation and the patients received 10 ml tranexamic acid and 10 ml physiological saline). The postoperative hemoglobin level, maximum hemoglobin loss, wound drainage, blood loss, the volume of blood transfusion, the number of patients inquiring blood transfusion, venous thrombo embolism rate, and ecchymosis rate were recorded and compared among the four groups.
