Marijuana use is inversely associated with liver steatosis detected by transient elastography in the general United States population in NHANES 2017-2018: A cross-sectional study.

Background: The impact of marijuana on the general population is largely unknown. The present study aimed to assess the association between marijuana use and liver steatosis and fibrosis in the general United States population utilizing data from the National Health and Nutrition Examination Survey (NHANES).

Methods: This cross-sectional study was performed with data from the 2017-2018 cycle of NHANES.

Clinical Value of Ultrasound-Guided Minimally Invasive Biopsy in the Diagnosis or Treatment of Breast Nodules.

Purpose: To explore the clinical value of ultrasound-guided minimally invasive biopsy of breast nodules for diagnosis and treatment of patients with no positive clinical signs on manual breast examination.

Methods: We performed a retrospective review of 136 patients with no signs on breast palpation who underwent ultrasound-guided minimally invasive biopsy. A total of 63 patients underwent breast nodule resection from October 2018 to December 2019 at the General Hospital of Central Theater Command of the People's Liberation Army.

[Changes of serum neuron-specific enolase and serum ferritin levels in patients with pneumoconiosis].

Objective: To investigate the changes in serum neuron-specific enolase (NSE) and serum ferritin (SF) in patients with pneumoconiosis and their relationship with the onset of pneumoconiosis.

Methods: The serum NSE and SF levels in the peripheral blood of patients with pneumoconiosis were measured by electrochemical fluorescence immunoassay.

Results: The patients with first-stage pneumoconiosis and second-stage pneumoconiosis had significantly higher serum NSE and SF levels than the control group (23.

[Destruction of Walker-256 tumor vasculature by a novel ultrasound cavitation technique].

Objective: To explore the feasibility of disrupting tumor microcirculation by the cavitation of microbubbles enhanced ultrasound (US) and analyze its pathological mechanism.

Methods: Twenty-four SD male rats with subcutaneously transplanted Walker-256 tumor were divided into 3 groups, i.e.

Animal model of ascending aortic stenosis in rabbits without endotracheal intubation.

Background And Aim: Experimental animal studies of left ventricular hypertrophy (LVH) usually involve endotracheal intubation, which is associated with a risk of serious tracheal injury and other significant negative sequelae. We developed an animal model of pressure overload hypertrophy caused by constriction of the ascending aorta in rabbits that does not require endotracheal intubation.

Methods: New Zealand White rabbits of either sex (1.

[Expression of midkine and vascular endothelial growth factor in bone marrow of patients with multiple myeloma and its significance].

The purpose of this study was to explore the expressions of midkine (MK) and vascular endothelial growth factor (VEGF) in multiple myeloma (MM), and to evaluate their relation with angiogenesis and prognosis. The expression levels of MK and VEGF in bone marrow mononuclear cells of 31 MM patients in different stages and 20 controls were detected by real-time fluorescent quantitative RT-PCR. The results showed that the MM patients had significantly higher MK and VEGF expression level than control group (p < 0.
