A diagnostic test of three-dimensional magnetic resonance elastography imaging for preoperative prediction of microvascular invasion in patients with T1 stage clear cell renal carcinoma.

Background: Detection of microvascular invasion (MVI) of kidney tumors is important for selecting the optimal therapeutic strategy. Currently, the prediction of MVI lacks an accurate imaging biomarker. This study evaluated the performance of three-dimensional (3D) magnetic resonance elastography (MRE) imaging in predicting microvascular invasion (MVI) of T1 stage clear cell renal carcinoma (ccRCC).

[Ameliorative Effects of Cang-ai Volatile Oil on Left Ventricular Remodeling in Rats].

Objective: To evaluate with 7T cardiac magnetic resonance tissue tracking imaging (CMR-TT) the ameliorative effect of Cang-ai volatile oil (CAVO) on left ventricular remodeling (LVR) in rats induced by isoproterenol (ISO), and to make preliminary investigation into CAVO's effects on endothelial dysfunction in LVR.

Methods: A total of 35 healthy male Sprague-Dawley (SD) rats were randomly assigned to two groups, the experimental group ( =27) and the normal control group ( =8). The rat model of LVR was established by subcutaneous injection of ISO solution at 10 mg·kg ·d at multiple sites for 10 consecutive days.

Does the Level of Syndesmotic Screw Insertion Affect Clinical Outcome after Ankle Fractures with Syndesmotic Instability?

Objective: Ankle fractures are often combined with syndesmotic instability, requiring reduction and stabilization. However, the optimal level for syndesmotic screw positioning remains unclear. This study aims to evaluate the effect of different syndesmotic screw insertion levels on postoperative clinical outcomes and determine whether an optimal level exists.

Comparison of Posteromedial Versus Posterolateral Approach for Posterior Malleolus Fixation in Trimalleolar Ankle Fractures.

Objective: To compare clinical and radiographic outcomes of posterior malleolar fractures (PMF) treated with lag screws from anterior to posterior versus posterior to anterior approach.

Methods: We retrospectively analyzed 48 patients with trimalleolar fractures who underwent open reduction and internal fixation (ORIF) with either posteromedial (PM) or posterolateral (PL) approaches between January 2012 and December 2014. Fixation of the posterior malleolus was made with anteroposterior screws in 20 patients using the PM approach and posteroanterior screws in 28 patients using the PL approach.

Antioxidant and physiological effects of Si-Wu-Tang on skin and liver: a randomized, double-blind, placebo-controlled clinical trial.

Background: Si-Wu-Tang (SWT) is used to treat various gynecological disorders in Chinese medicine. This study investigated the antioxidant and physiological effects of SWT on the skin and liver in healthy adults.

Methods: This randomized, crossover, double-blind, placebo-controlled clinical trial was conducted at Chung Shan Medical University Hospital in December 2008.

Diagnostic Utility of Diffusion-weighted Magnetic Resonance Imaging in Differentiating Small Solid Renal Tumors (≤ 4 cm) at 3.0T Magnetic Resonance Imaging.

Background: The aim of this study was to assess the performance of apparent diffusion coefficient (ADC) measurement obtained with diffusion-weighted magnetic resonance imaging (DW-MRI) to distinguish renal cell carcinomas (RCCs) from small benign solid renal tumors (≤ 4 cm).

Methods: In this cross-sectional study, 49 consecutive patients with histopathologically confirmed small solid renal tumors, and seven healthy volunteers were imaged using nonenhanced MRI and DW-MRI. The ADC map was calculated using the b values of 0, 50, 400, and 600 s/mm 2 and values compared via the Kruskal-Wallis and Mann-Whitney tests.

Interventions for treating displaced midshaft clavicular fractures: a Bayesian network meta-analysis of randomized controlled trials.

Displaced midshaft clavicle fractures are frequent injuries. There are 3 treatment methods including conservative treatment, plate fixation, and intramedullary pin fixation. However, which is the best treatment remains a topic of debate.

Individualized management of pregnant women with high hepatitis B virus DNA levels.

Hepatitis B is a major health concern in the Asia-Pacific region, and is endemic in China, Southeast Asia, and Africa. Chronic hepatitis B virus (HBV) infection may cause hepatic cirrhosis and liver cancer. It is estimated that there are more than 350 million chronic HBV carriers worldwide, of whom approximately one quarter will die of chronic hepatitis B-related liver diseases.

Expression of interferon-γ in decidual natural killer cells from women with hypertensive disorder complicating pregnancy.

Aim: Hypertensive disorder complicating pregnancy (HDCP) is one of the most frequent and serious pregnancy-related diseases, which is closely related to disorders of the maternal immune system, especially the local immune microenvironment of the maternal-fetal interface. Uterine decidual natural killer (dNK) cells are the major immune cells in the maternal-fetal interface and they play an important role in establishing and maintaining a normal pregnancy. The aim of this study was to investigate the phenotype and function of dNK cells from women with HDCP.

Determination of astaxanthin in Haematococcus pluvialis by first-order derivative spectrophotometry.

A highly selective, convenient, and precise method, first-order derivative spectrophotometry, was applied for the determination of astaxanthin in Haematococcus pluvialis. Ethyl acetate and ethanol (1:1, v/v) were found to be the best extraction solvent tested due to their high efficiency and low toxicity compared with nine other organic solvents. Astaxanthin coexisting with chlorophyll and beta-carotene was analyzed by first-order derivative spectrophotometry in order to optimize the conditions for the determination of astaxanthin.

Retroperitoneal neoplasms within the perirenal space in infants and children: differentiation of renal and non-renal origin in enhanced CT images.

Purpose: To retrospectively demonstrate the specific CT findings of retroperitoneal neoplasms to diagnosis and differential diagnosis renal and non-renal tumors within the perirenal space in infants and children.

Materials And Methods: We retrospectively reviewed the clinical data and CT images of 42 consecutive patients with surgically and pathologically proven retroperitoneal neoplasms within the perirenal space. The patients were divided into renal tumors group (n=16) and non-renal tumors group (n=26).

[Renal and non-renal tumors within the perirenal space in infants and children: multi-detector row CT characteristics].

Objective: To determine the characteristics of Multi-detector Row CT (MDCT) image in distinguishing renal tumors from non-renal tumors within the perirenal space in infants and children.

Methods: Data from 40 patients with surgically and pathologically proved retroperitoneal neoplasms within the perirenal space were collected. Based on the pathological findings, the patients were divided into renal tumor group (n=14) and non-renal tumor group (n=26).

Effects of problem-oriented willed-movement therapy on motor abilities for people with poststroke cognitive deficits.

Background And Purpose: Cognitive deficits after stroke are common and interfere with recovery. One purpose of this study was to determine whether the motor abilities of subjects who have poststroke cognitive deficits and who have received problem-oriented willed-movement (POWM) therapy will improve more than the motor abilities of subjects in the reference group who have received neurodevelopmental treatment (NDT). Another purpose of this study was to identify the relationship between cognitive function and motor abilities for both groups.
