[Preoperative Incidence of Deep Venous Thrombosis and Its Risk Factors in Older Patients with Hip Fracture].

Purpose Of The Study: Hip fractures in the elderly are commonly complicated by deep venous thrombosis (DVT), particularly in the preoperative phase. This retrospective study aimed to determine the preoperative incidence of DVT and identify its risk factors in older patients with hip fractures.

Material And Methods: This single-center retrospective study enrolled 278 patients (aged ≥ 60 years) with unilateral hip fracture, who underwent color Doppler ultrasonography of the lower extremity veins on the day of surgery at the Second People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine between 1st January 2015 and 31st December 2020.

Predictive factors for persistent postoperative hydrocephalus in children undergoing surgical resection of periventricular tumors.

Objective: The aim of this study is to identify the factors predicting persistent hydrocephalus after periventricular tumor resection in children and assess the need and efficacy of perioperative cerebrospinal fluid (CSF) intervention.

Methods: We performed a retrospective analysis of pediatric patients who underwent resection surgery of a periventricular tumor between March 2012 and July 2021 at the Department of Neurosurgery in Zhujiang Hospital of South Medical University. Demographic, radiographic, perioperative, and dispositional data were analyzed using univariate and multivariate models.

Eltoprazine modulated gamma oscillations on ameliorating L-dopa-induced dyskinesia in rats.

Aim: Parkinson's disease (PD) is a pervasive neurodegenerative disease, and levodopa (L-dopa) is its preferred treatment. The pathophysiological mechanism of levodopa-induced dyskinesia (LID), the most common complication of long-term L-dopa administration, remains obscure. Accumulated evidence suggests that the dopaminergic as well as non-dopaminergic systems contribute to LID development.

Sound Localization of Listeners With Normal Hearing, Impaired Hearing, Hearing Aids, Bone-Anchored Hearing Instruments, and Cochlear Implants: A Review.

Purpose: This review article reviews the contemporary studies of localization ability for different populations in different listening environments and provides possible future research directions.

Conclusions: The ability to accurately localize a sound source relying on three cues (interaural time difference, interaural level difference, and spectral cues) is important for communication, learning, and safety. Confounding effects including noise and reverberation, which exist in common listening environments, mask or alter localization cues and negatively affect localization performance.

Identification of PBK as a hub gene and potential therapeutic target for medulloblastoma.

Medulloblastoma (MB) is the most frequent malignant brain tumor in pediatrics. Since the current standard of care for MB consisting of surgery, cranio‑spinal irradiation and chemotherapy often leads to a high morbidity rate, a number of patients suffer from long‑term sequelae following treatment. Targeted therapies hold the promise of being more effective and less toxic.

Circ-SKA3 upregulates ID3 expression by decoying miR-326 to accelerate the development of medulloblastoma.

Medulloblastoma (MB), the most common malignant childhood brain tumor, is a serious threat to life. Circular RNA (circRNA) is involved in the development of various cancers, including MB. We aimed to explore the role of circRNA spindle and kinetochore associated complex subunit 3 (circ-SKA3) in MB progression.

Using Three-Dimensional Printing to Create Individualized Cranial Nerve Models for Skull Base Tumor Surgery.

Objective: Using three-dimensional (3D) printing to create individualized patient models of the skull base, the optic chiasm and facial nerve can be previsualized to help identify and protect these structures during tumor removal surgery.

Methods: Preoperative imaging data for 2 cases of sellar tumor and 1 case of acoustic neuroma were obtained. Based on these data, the cranial nerves were visualized using 3D T1-weighted turbo field echo sequence and diffusion tensor imaging-based fiber tracking.

Establishment of a rhesus monkey model of chronic temporal lobe epilepsy using repetitive unilateral intra-amygdala kainic acid injections.

Objective: Temporal lobe epilepsy (TLE) is a common type of acquired epilepsy refractory to medical treatment. As such, establishing animal models of this disease is critical to developing new and effective treatment modalities. Because of their small head size, rodents are not suitable for comprehensive electroencephalography (EEG) evaluation via scalp or subdural electrodes.

[An epidemic outbreak of respiratory infection caused by Chlamydia pneumoniae in medical workers].

Objective: To investigate the clinical manifestations and the chest imaging characteristics of an epidemic outbreak of respiratory infection caused by Chlamydia pneumoniae (CP).

Methods: A prospective study for CP infection in 15 patients from September 2003 was carried out. Sputum and throat swab specimen were obtained and CP DNA was detected by polymerase chain reaction (PCR).
