Giant cell tumor of tendon sheath: A report of 216 cases.

Background: In this article on giant cell tumor of tendon sheath (GCTTS), we intend to summarize and analyze the clinical and pathological features of GCTTS hoping to improve clinical management and patient treatment.

Methods: The study retrospectively reviewed 216 patients of GCTTS, registered at the Affiliated Hospital of Southwest Medical University from January 2010 to December 2020. These cases were diagnosed by surgical excision.

Iron chelation suppresses secondary bleeding after intracerebral hemorrhage in angiotensin II-infused mice.

Aims: Secondary bleeding and further hematoma expansion (HE) aggravate brain injury after intracerebral hemorrhage (ICH). The majority of HE results from hypertensive ICH. Previous study reported higher iron content in the brains of hypertensive patients.

The Application of Fine Needle Aspiration Biopsy in the Diagnosis of Axillary Masses.

Introduction: We intend to determine the diagnostic power of fine needle aspiration biopsy (FNAB) for differentiation between malignant and benign lesions on axillary masses and draw the physicians' attention to the benefits of FNAB cytology in the diagnosis of axillary masses.

Methods: In this study, 1,328 patients with an axillary mass diagnosed by FNAB were retrospectively reviewed. These cases were registered at the affiliated hospital of Southwest Medical University (China), July 2014 to June 2017.

Nicotinamide riboside rescues angiotensin II-induced cerebral small vessel disease in mice.

Aims: Hypertension is a leading cause of cerebral small vessel disease (CSVD). Currently, treatments for CSVD are limited. Nicotinamide riboside (NR) can protect against vascular injury and cognitive impairment in neurodegenerative diseases.

Two Sympatric Species Could Mutually Recognize Sex Pheromone Components for Behavioral Isolation.

and are two sympatric species in China and many other countries. Both moths employ a multiple component sex pheromone blend, including a common component Z9,E12-14:OAc, and two specific components Z9-14:OH and Z11-16:OAc for , and one specific component Z9,E11-14:OAc for For the two species, it has been well documented that males are able to recognize and behaviorally attracted by their species-specific sex pheromone, which functions as a means of reproductive isolation, but whether males could mutually recognize pheromone components of its sympatric species is unknown. In the present study, the electroantennogram (EAG) and field evaluation were conducted to address this topic.

The spin-dependent Seebeck effect and the charge and spin figure of merit in a hybrid structure of single-walled carbon nanotubes and zigzag-edge graphene nanoribbons.

A hybrid structure of carbon nanotubes and graphene nanoribbons was predicted and synthesized (Y. Li et al., Nat.

[Effect of naloxone on expression of Bcl-2 protein and tumor necrosis factor-alpha in rats with acute myocardial ischemia/reperfusion injury].

Objective: To investigate the effect of naloxone on myocardial cell apoptosis and apoptosis-related gene Bcl-2 in rats with acute myocardial ischemia/reperfusion (AMIR) injury, and explore the mechanism of protective effect of naloxone on myocardium.

Methods: Thirty SD rats were randomly divided into three groups (n=10): ischemia/reperfusion group, naloxone preconditioning group (naloxone was injected intraperitoneally 10 minutes before ischemia and 2 hours after reperfusion), and normal control group. The left anterior descending branch (LAD) of rat coronary artery was tied and un-tied in ischemia/reperfusion group and naloxone preconditioning group to establish the AMIR model in rats.
