To evaluate effects of microwave ablation with a 2,450-MHz internally cooled-shaft antenna in animal experiments and in a clinical study. Microwave ablation was performed using a cooled-shaft antenna in eight in vivo (36 ablations) porcine livers. The coagulation diameters achieved in different microwave ablation parameter groups were compared. Sixty(More)
Cancer immunotherapy is the most exciting advancement in cancer therapy. Similar to immune checkpoint blockade and chimeric antigen receptor T cell (CAR-T), bispecific antibody (BsAb) is attracting more and more attention as a novel strategy of antitumor immunotherapy. BsAb not only offers an effective linkage between therapeutics (e.g., immune effector(More)
OBJECTIVE To explore the potential risk factors of abdominal aortic aneurysm (AAA) in the Chinese population. METHODS A matched case-control study was designed for the study. Patients with AAA administrated in the First Affiliated Hospital of Zhengzhou University from January 2005 to December 2007 were included in the study. Sex and age-matched volunteers(More)
Thoracogastric airway fistula (TGAF) is a rare and dangerous complication of esophagectomy performed for esophageal and cardiac carcinomas. Herein, we aimed to explore the feasibility and efficacy of individualized airway stent implantation for the treatment of TGAF after esophagectomy. Based on different TGAF types and relevant data on chest computed(More)
BACKGROUND To address the limitations of silicone stents, we designed a hinged self-expandable covered metallic stent. The aim of this study was to evaluate the safety and efficacy of the customized stents in clinical applications. METHODS This was a retrospective analysis. Under conscious sedation and local anesthesia, the stents were implanted or(More)
This retrospective study aimed to demonstrate and compare the safety and effectiveness of computed tomography-guided radiofrequency ablation (RFA) and 125I-seed brachytherapy for painful bone metastases after failure of external beam radiotherapy (EBRT). From June 2013 to October 2015, 79 patients with moderate-to-severe pain caused by metastatic bone(More)
Background For patients having a severe larynx or tracheal stenosis, emergency endotracheal intubation (EEI) may be needed due to respiratory failure. Purpose To evaluate the feasibility and effectiveness of awake EEI using a fluoroscopy-guided sheath-assisted technique for adult patients having a malignant tracheal stenosis. Material and Methods From(More)
This study aimed at assessing the usefulness of flat detector cone-beam CT virtual navigation-guided transthoracic needle biopsy of small (≤2.0 cm) pulmonary nodules in terms of diagnostic accuracy and complications to evaluate the diagnostic performance and complications of small pulmonary nodules under cone-beam CT (CBCT) guidance. A total of 100 patients(More)
BACKGROUND AND OBJECTIVES Perforated esophageal carcinoma with mediastinal abscess is a clinically life-threatening emergency. Herein, we summarize our experience with placement of transnasal drainage catheters and covered esophageal stents for the treatment of this condition. METHODS We retrospectively assessed the medical records of 20 patients who were(More)
To evaluate the intermediate outcomes of temporary partially covered tracheobronchial stenting in patients with benign tracheobronchial stenosis. We conducted a retrospective study of patients with benign tracheobronchial stenosis who underwent stent placement. All stents were removed approximately 3 months after placement. Respiratory function was assessed(More)
