Clinical results of knee juxta-articular giant-cell tumors treated with bone cement filling and internal fixation after extensive curettage.

Objectives: This study was to evaluate the radiological and clinical outcomes of patients with juxta-articular giant-cell tumors (GCTs) around the knee treated with bone cement filling and internal fixation after extensive curettage.

Patients And Methods: A total of 15 patients (6 males, 9 females; mean age: 35.3±8.

The discrepancy between objective and subjective assessments of catastrophic health expenditure: evidence from China.

The pro-rich nature of catastrophic health expenditure (CHE) indicators has garnered criticism, inspiring the exploration of the subjective approach as a complementary method. However, no studies have examined the discrepancy between subjective and objective approaches. Employing data from the Chinese Social Survey (CSS) 2013-2021 waves, we analysed the discrepancy between objective and subjective CHE and its associated socioeconomic factors using logit regression modelling.

Battle to Survive: The Association Between Accountability and Chinese Local Government Response to COVID-19.

China's ability to sustain the zero-COVID strategy over three years has garnered global attention, but little is known about the factors contributing to its long-term adherence. Based on the political promotion tournament model, this article theorizes that China's strict administrative accountability system, which tied local officials' career prospects to their performance in crucial policy goals, incentivized local governments to sustain COVID-19 policies. Using data from the Oxford COVID-19 Government Response Tracker and major official Chinese media outlets, we performed interrupted time series analysis (ITSA) to examine whether the accountability events affected the local government's COVID-19 responses.

Flavan-3-ol monomers intake is associated with osteoarthritis risk in Americans over 40 years of age: results from the National Health and Nutritional Examination Survey database.

: Osteoarthritis (OA) stands as the prevailing progressive musculoskeletal disease, serving as the primary cause of chronic pain and activity limitations among adults over 40. Flavan-3-ols, common polyphenolic compounds, are believed to harbor anti-inflammatory and anti-aging properties. This study explores the relationship between flavan-3-ol intake and osteoarthritis risk in individuals over the age of 40 in the US.

Magnesium Ions Promote the Induction of Immunosuppressive Bone Microenvironment and Bone Repair through HIF-1α-TGF-β Axis in Dendritic Cells.

The effect of immunoinflammation on bone repair during the recovery process of bone defects needs to be further explored. It is reported that Mg can promote bone repair with immunoregulatory effect, but the underlying mechanism on adaptive immunity is still unclear. Here, by using chitosan and hyaluronic acid-coated Mg (CSHA-Mg) in bone-deficient mice, it is shown that Mg can inhibit the activation of CD4 T cells and increase regulatory T cell formation by inducing immunosuppressive dendritic cells (imDCs).

Understanding China's shifting priorities and priority-setting processes in development assistance for health.

Over the past two decades, China has become a distinctive and increasingly important donor of development assistance for health (DAH). However, little is known about what factors influence China's priority-setting for DAH. In this study, we provide an updated analysis of trends in the priorities of Chinese DAH and compare them to comparable trends among OECD Development Assistance Committee (DAC) donors using data from the AidData's Global Chinese Development Finance Dataset (2000-2017, version 2.

Characteristic Features of Deep Brain Lymphatic Vessels and Their Regulation by Chronic Stress.

Studies have demonstrated that a functional network of meningeal lymphatic vessels exists in the brain. However, it is unknown whether lymphatic vessels could also extend deep into the brain parenchyma and whether the vessels could be regulated by stressful life events. We used tissue clearing techniques, immunostaining, light-sheet whole-brain imaging, confocal imaging in thick brain sections and flow cytometry to demonstrate the existence of lymphatic vessels deep in the brain parenchyma.

Intra-articular administration of adrenaline plus an irrigation pump system for visibility during the arthroscopic reconstruction of multiple knee ligaments without a tourniquet.

Objective: Multiple ligament knee injuries (MLKIs) are rare but severe systemic trauma. Single surgery in the acute setting is preferred, although with an extended operation time. To avoid the complications associated with a tourniquet, we herein describe a method for visibility without a tourniquet: intra-articular administration of adrenaline plus an irrigation pump system.

Hyperspectral imaging for accurate determination of rice variety using a deep learning network with multi-feature fusion.

The phenomena of rice adulteration and shoddy rice arise continuously in high-quality rice and reduce the interests of producers, consumers and traders. Hyperspectral imaging (HSI) was conducted to determine rice variety using a deep learning network with multiple features, namely, spectroscopy, texture and morphology. HSI images of 10 representative high-quality rice varieties in China were measured.

Rapid detection of adulteration of minced beef using Vis/NIR reflectance spectroscopy with multivariate methods.

High economic returns induce the continuous occurrence of meat adulteration. In this study, visible/near-infrared (Vis/NIR) reflectance spectroscopy with multivariate methods was used for the rapid detection of adulteration in minced beef. First, the reflectance spectra of different adulterated minced beef samples were measured at 350-2500 nm.
