Dynamic computed tomography manifestations of simulated wooden foreign bodies in blood-saline mixtures with variable concentrations and retention times.

Diagnosing wooden foreign bodies (WFBs) using computed tomography (CT) is often missed, leading to adverse outcomes. This study aims to reduce misdiagnoses by exploring the density variation of blood-saline mixtures in ex vivo models. Twenty Cunninghamia lanceolata sticks, selected as WFB models, were randomly assigned to five groups: a control group (saline) and four experimental groups immersed in blood-saline mixtures with varying concentrations.

LINC01207 promotes prostate cancer progression by sponging miR-1182 to upregulate AKT3.

Prostate cancer (PC) is recognized as a common malignancy in male patients. Long non-coding RNA (lncRNA) has been implicated in the development of PC. Recently, long intergenic non-protein coding RNA 1207 (LINC01207) has been reported to regulate the carcinogenesis of multiple cancer types.

SMAC mimetic birinapant inhibits hepatocellular carcinoma growth by activating the cIAP1/TRAF3 signaling pathway.

The present study investigated the effects and molecular mechanism of the second mitochondria‑derived activator of caspase (SMAC) mimetic birinapant on the proliferation and apoptotic rate of liver cancer cells. Western blotting and reverse transcription‑quantitative PCR were used to detect the protein and mRNA expression levels of cellular inhibitor of apoptosis 1 (cIAP1) and tumor necrosis factor receptor‑associated factor 3 (TRAF3) in the liver cancer cell lines Huh7, H22 and HepG2, and the hepatocyte line AML12. Annexin V‑FITC and Transwell assays were used to assess the effect of birinapant pretreatment on the apoptotic rate and invasive ability of liver cancer cells.

[Application of CT and MRI in the Diagnosis of Paragonimiasis in Brain and Spinal Cord].

Clinical data of 22 cases with paragonimiasis in brain and spinal cord in the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture during 2003 -2012 were retrospectively analyzed. Twenty-two cases aged from 6 to 17 years old, including 15 males and 7 females, were from the countryside, and had a history of eating raw crabs. CT and MRI showed that all the cases had cerebral lesion, 16 cases had unilateral lesion of cerebral hemisphere, and 6 cases had bilateral hemisphere lesions.

Size-controlled preparation of α-calcium sulphate hemihydrate starting from calcium sulphate dihydrate in the presence of modifiers and the dissolution rate in simulated body fluid.

Different-sized α-calcium sulphate hemihydrate (α-CSH) rods were hydrothermally prepared by converting calcium sulphate dihydrate at 110-140°C in the presence of MgCl2, sodium citrate (CANa), and sodium dodecyl benzene sulfonate (SDBS) as the modifiers. The α-CSH rods with the average diameters and the average lengths in the ranges of 2.6-5.

Shockwaves induce osteogenic differentiation of human mesenchymal stem cells through ATP release and activation of P2X7 receptors.

Shockwave treatment promotes bone healing of nonunion fractures. In this study, we investigated whether this effect could be due to adenosine 5'-triphosphate (ATP) release-induced differentiation of human mesenchymal stem cells (hMSCs) into osteoprogenitor cells. Cultured bone marrow-derived hMSCs were subjected to shockwave treatment and ATP release was assessed.

Cemented bipolar hemiarthroplasty with a novel cerclage cable technique for unstable intertrochanteric hip fractures in senile patients.

Objective: To observe the clinical result and assess clinical value of cemented bipolar hemiarthroplasty with a novel cerclage cable technique for treatment of unstable intertrochanteric hip fractures in senile patients.

Methods: Forty-eight consecutive patients with unstable intertrochanteric fractures were treated in our hospital from March 2001 to March 2006 (Evans type III in 11 cases, Evans type IV in 25 cases and Evans type V in 22 cases). All the cases were evaluated by Zuckerman functional recovery score (FRS) and operative risk assessment software 1 (ORAS1), which were based on the patients' physical and laboratory examinations preoperatively.

Treatment of intertrochanteric fractures of the femur with L-trapezoid compression plate and its mechanical principles.

OBJECTIVE: To improve the results of the treatment of unstable types of intertrochanteric fractures of the femur (ITFF) by internal fixation. METHODS: A L-trapezoid compression plate system (L-TCP) was designed and compared to the AO/ASIF angle plates of 95 and 130 (L-AP) with mechanical tests. An Evans Type III model was made, the simulation electrical test with loading on single and both legs were done.
