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.

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.

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.
