3-Diethylaminopropyl isothiocyanate modified glycol chitosan for constructing mild-acid sensitive electrospinning antibacterial nanofiber membrane.

Bacterial infections would cause pathological inflammation and even generate chronic wound. Herein, a ciprofloxacin (Cip)-loaded mild acid-responsive electrospinning nanofiber membrane (NFM) containing 3-diethylaminopropyl isothiocyanate material grafted glycol chitosan (GC-DEAP) was fabricated to prevent bacterial infection against hemostatic and inflammatory phases of wounds. The presence of Cip and GC-DEAP in the objective NFM (PCL/GC-DEAP/Cip) was confirmed through XRD and FTIR.

Risk prediction of intraoperative pain in percutaneous microwave ablation of lung tumors under CT guidance.

Objectives: To evaluate the effect of intraoperative pain in microwave ablation of lung tumors (MWALT) on local efficacy and establish the pain risk prediction model.

Methods: It was a retrospectively study. Consecutive patients with MWALT from September 2017 to December 2020 were divided into mild and severe pain groups.

Differences in left and right carotid plaque vulnerability in patients with bilateral carotid plaques: a CARE-II study.

Background And Purpose: Atherosclerosis is a very complex process influenced by various systemic and local factors. Therefore, in patients with bilateral carotid plaques (BCPs), there may be differences in carotid plaque vulnerability between the sides. We aimed to investigate the differences in BCP characteristics in patients with BCPs using magnetic resonance vessel wall imaging (MR-VWI).

Preoperative computed tomographic-guided percutaneous coil localization of pulmonary nodules: 184 Cases in Single-center.

Objectives: The aim of this study was to evaluate the feasibility, accuracy, and safety of computed tomographic (CT)-guided coil localization before video-assisted thoracoscopic surgery.

Methods: One hundred and eighty-four consecutive patients with 200 pulmonary nodules who underwent CT-guided percutaneous coil localization before thoracoscopic surgery were retrospectively analyzed in this study. Success rate for localization, complication rates, CT findings, and pathological results of the lesions, as well as the data related to surgery were all recorded and analyzed.

Bilaterally Asymmetric Associations Between Extracranial Carotid Artery Atherosclerosis and Ipsilateral Middle Cerebral Artery Stenosis in Symptomatic Patients: A CARE-II Study.

Objective: To determine the bilaterally asymmetrical associations between extracranial carotid artery atherosclerosis and ipsilateral middle cerebral artery (MCA) stenosis in symptomatic patients using magnetic resonance vessel wall imaging. Approach and Results: Patients with symptomatic carotid artery atherosclerosis were recruited from the Chinese Atherosclerosis Risk Evaluation, a multicenter study. All subjects underwent intracranial magnetic resonance angiography and extracranial carotid artery magnetic resonance imaging.

Comparison of Carotid Atherosclerosis between Patients at High Altitude and Sea Level: A Chinese Atherosclerosis Risk Evaluation Study.

Objectives: To investigate the differences in characteristics of carotid plaques between patients Xining at high altitude and Jinan at sea level using magnetic resonance (MR) imaging.

Methods: Subjects were recruited from a cross-sectional, observational, multicenter imaging study of CARE-II study. Forty-nine (mean age 63.

Invasive placenta previa: Placental bulge with distorted uterine outline and uterine serosal hypervascularity at 1.5T MRI - useful features for differentiating placenta percreta from placenta accreta.

Objectives: To characterise MRI features of invasive placenta previa and to identify specific features for differentiating placenta percreta (PP) from placenta accreta (PA).

Methods: Forty-five women with PP and 93 women with PA who underwent 1.5T placental MRI were included.

Usefulness of radiological findings for predicting cochlear implantation outcomes in children with cochlear nerve deficiency: a pilot study.

Conclusion: Children with CND received limited benefits from CIs and their results varied. The size of the vestibulocochlear nerve relative to the facial nerve could potentially be used as a predicator for CI outcomes in children with CND.

Objective: This study aimed to (1) retrospectively review the outcomes of cochlear implants (CIs) in children with cochlear nerve deficiency (CND) and (2) evaluate the clinical usefulness of radiological findings as predictors for post-implantation outcomes.

[Efficacy of endolymphatic sac-mastoid shunt surgery for intractable Meniere's disease].

Objective: To investigate the effect and mechanism of endolymphatic sac-mastoid shunt surgery for intractable Meniere's disease of different stages according to hearing level.

Methods: Data from 240 patients diagnosed with unilateral MD strictly meeting the criteria issued by Chinese Academy of Otolaryngology-Head and Neck Surgery Committee (2006) from January 1983 to January 2012 were analyzed in this study. Endolymphatic sac-mastoid shunt surgery was performed in affected ear for each patient.

Diffusion measurement of intraplaque hemorrhage and intramural hematoma using diffusion weighted MRI at 3T in cervical artery.

Objectives: To assess the difference between carotid haemorrhagic plaque and non-haemorrhagic plaque by using diffusion-weighted imaging (DWI) and to evaluate carotid intraplaque haemorrhage (IPH) and intramural hematoma (IMH) of cervical artery dissection with apparent diffusion coefficient (ADC) measurement.

Methods: Fifty-one symptomatic patients underwent 3.0-T carotid MR imaging, including conventional sequences, three-dimensional (3D) magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequence, and DWI.

Deep-gray nuclei susceptibility-weighted imaging filtered phase shift in patients with Wilson's disease.

Background: Susceptibility-weighted imaging (SWI) is a useful tool for evaluating brain paramagnetic mineralization. The aim of this study was to evaluate SWI filtered phase shift in brain gray nuclei of Wilson's disease (WD).

Methods: Twenty-three WD patients and 23 age- and gender-matched healthy controls underwent SWI.

[Visualization of endolymphatic hydrops in 3D-FLAIR MRI after intratympanic Gd-DTPA administration in Meniere's disease patients].

Objective: To study the feasibility of endolymphatic visualization and the diagnosis of Meniere's disease by applying intratympanic gadolinium administration through the tympanic membrance and three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI). To study the relationship between the endolymphatic hydrops visualized by MRI and audio-vestibular functional tests, such as pure tone audiometry (PTA), electrocochleography (EcoG), caloric test and vestibular evoked myogenic potential (VEMP).

Methods: With a three Tesla magnetic resonance imaging (MRI) unit, 3D-FLAIR imaging was performed 24 hours after intratympanic gadolinium through the tympanic membrance in 32 patients with clinically diagnosed unilateral Meniere's Disease.
