Nomogram based on the O-RADS for predicting the malignancy risk of adnexal masses with complex ultrasound morphology.

Objective: The accurate preoperative differentiation of benign and malignant adnexal masses, especially those with complex ultrasound morphology, remains a great challenge for junior sonographers. The purpose of this study was to develop and validate a nomogram based on the Ovarian-Adnexal Reporting and Data System (O-RADS) for predicting the malignancy risk of adnexal masses with complex ultrasound morphology.

Methods: A total of 243 patients with data on adnexal masses with complex ultrasound morphology from January 2019 to December 2020 were selected to establish the training cohort, while 106 patients with data from January 2021 to December 2021 served as the validation cohort.

Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing.

In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs.

Exploring japonica rice epigenetic diversity in the main production regions of Heilongjiang Province.

As a major epigenetic modification, DNA methylation plays an important role in coordinating plant responses to environmental changes. Methylation-sensitive amplified polymorphism (MSAP) technology was used in this study to investigate the epigenetic diversity of fifty japonica rice samples from five regions in Heilongjiang Province, China. In addition, the phenotypic indicators of japonica rice samples and the environmental conditions of the sampling sites were investigated and analysed.

Patient reported outcomes and quality of life in Chinese patients with implantable cardioverter defibrillators.

Objectives: Patient reported outcomes in Implantable Cardioverter Defibrillator (ICD) patients can describe the experience of living with heart disease and with an ICD. However, very little is known about patient outcomes among Chinese patients which may limit effective patient discussions and interventions for these patients. The purposes of this study were to examine device related experiences (e.

Changes in secondary structure of myofibrillar protein and its relationship with water dynamic changes during storage of battered and deep-fried pork slices.

Fourier transform infrared spectroscopy was used to analyze the changes of secondary structure of myofibrillar proteins in short-term storage of battered and deep-fried pork slices. These changes were combined with low-field NMR analysis results to analyze the correlation between secondary structure and dynamic changes of water content. The results showed that the number of α-helix and β-sheet decreased by 22.

Ultrasound diagnosis of intramural pregnancy.

Intramural pregnancy is a rare type of ectopic pregnancy, where the gestational sac is implanted inside the myometrium instead of the endometrial and fallopian tubes. Preoperative diagnosis remains very difficult. Ultrasonic findings vary according to the anatomical location or duration of pregnancy.

[Cognitive function and factors related to cognitive function in hospitalized patients with chronic heart failure].

Objective: To explore the cognitive function status and potential influence factors on cognitive function in hospitalized patients with chronic heart failure.

Methods: Using a cross-sectional research design, CHF patients (n = 267, mean age (63.8 ± 9.

Arachidonate 5-lipoxygenase-activating protein (ALOX5AP) gene rs4073259 polymorphism not associated with ischemic stroke in the northeastern Chinese Han population.

Objective: Although recent evidence has implicated that 5-lipoxygenase activating protein (ALOX5AP) gene is associated with ischemic stroke (IS) risk, the underlying molecular mechanism remains to be defined. This study aimed to investigate the role of ALOX5AP rs4073259 in ischemic stroke in a Northeastern Chinese Han population.

Methods: A total of 501 IS patients and 497 healthy controls were enrolled for polymerase chain reaction (PCR) and ligase detection reaction (LDR) analysis of ALOX5AP rs4073259 single nucleotide polymorphism (SNP).

Role of ultrasound in diagnosing isolated torsion of fallopian tube.

Aim: To summarize the ultrasonic features of isolated fallopian tube torsion (IFTT) by retrospectively analyzing cases presenting at our hospital.

Methods: This analysis was approved by the ethical committee of our hospital. Medical records of surgically proven IFTT patients admitted to our hospital since 2002 were collected.

Association of imaging classification of intracranial cerebral atherosclerotic vascular stenosis in ischemic stroke and renalase gene polymorphisms.

Cerebral atherosclerosis vascular stenosis is a common etiology for ischemic stroke and a major factor in recurrent stroke and vascular mortality. Recent studies suggest that renalase plays a role in hypertension and ischemic stroke, and may be involved in atherosclerosis. The aim of the present study was to investigate whether there were correlations between single-nucleotide polymorphisms (SNPs) in the renalase gene and severity of intracranial cerebral atherosclerotic vascular stenosis in ischemic stroke patients as determined by imaging.

An association study on renalase polymorphisms and ischemic stroke in a Chinese population.

Ischemic stroke is a leading cause of death and adult disability worldwide. Recent research suggests that renalase is strongly associated with heart disease and hypertension and may play a role in ischemic stroke. In this study, we investigate the genetic association between renalase and ischemic stroke in a northern Chinese Han population.
