This study is a single-arm, open-label early exploratory clinical trial designed to evaluate the safety, tolerability, and preliminary efficacy of GC012F injection in subjects with refractory GMG. Additionally, the study aims to assess the pharmacokinetic (PK), pharmacodynamic (PD) characteristics, and immunogenicity of GC012F injection in subjects.
In this prospective analysis, investigators collected and evaluated data from patients who underwent TBB at the Respiratory Endoscopy Center of Sichuan Provincial People's Hospital. The procedures utilized a novel approach combining OCT with R-EBUS for guidance. Eligibility for participation was determined based on established guidelines for the application of diagnostic flexible bronchoscopy in adults. The admission criteria of this study were as followed: (1) voluntary participation and written informed consent signed, (2) age ≥ 18 years old, (3) the platelets count and PT, APTT tests were normal, (4) normal ECG, (5) found PPL's by chest computed tomography (CT) within 2 weeks and (6) could not detect the lesions through routine diagnostic bronchoscopy. The exclusion criteria of this study were as followed: (1) patients with contraindication of bronchoscopy (such as respiratory failure and acute cardio-cerebrovascular events), (2) patients who refuse biopsy because of physical reasons or personal wishes, (3) patients with the objective reasons (such as abundant blood supply around the lesion) who could not complete the biopsy, (4) patients who are participating in other clinical studies, (5) patients with poor compliance who are believed by the researchers to be unable to cooperate for the completion of the examination and follow-up, and (6) women who were pregnant. R-EBUS and OCT In this study, all procedures were conducted using a standardized flexible bronchoscopy (Olympus, Japan) featuring an outer diameter of 4.2mm. R-EBUS system (Olympus, Japan) incorporated an ultra-thin radial ultrasonic probe (Olympus UM-S20-17S), which measures merely 1.4mm in diameter. The OCT (Yongshida Medical Technology, Guangdong, China) probe is a cylindrical catheter, 1.7mm in diameter and 150cm in length. Placing the probe through the working channel of bronchoscope for real time dynamic scanning of lesions. Research Process In this study, the entirety of the procedures was performed by the same respiratory physician with 5 years of experience in respiratory endoscopic diagnosis and treatment, including preoperative evaluation, preparation, lesion localization and biopsy. The respiratory physician had examined the bilateral airways with flexible bronchoscopy after the completion of preoperative anesthesia and found no lesions. The subsequent step involved the precise placement of the OCT probe, guided by prior CT scan results. This stage was critical for marking the lesion, determining its nature (benign or malignant), and, in cases of malignancy, identifying its pathological classification. In instances where the OCT failed to identify any lesion, the R-EBUS was employed to facilitate lesion localization and biopsy. Conversely, when PPLs was detected via OCT, R-EBUS was additionally utilized to corroborate the PPLs localization and to assist in completing the biopsy procedure. For cases where OCT localization failed, R-EBUS would be used. After successful confirmation with R-EBUS, an attempt was made again to insert the OCT probe and completed biopsy. Rapid On-Site Evaluation (ROSE) was employed for the assessment of biopsy specimens. A total of five specimens were collected from each lesion and subjected to ROSE. In scenarios where ROSE provided a definitive diagnosis, no additional biopsies were deemed necessary. Conversely, in instances where ROSE yielded non-definitive results, further biopsy samples were obtained. All biopsy specimens were preserved in 10% formalin, preparing them for detailed histopathological analysis. The ultimate pathological diagnoses were determined based on the reports issued by the pathology department. In this study, the demographics of all patients were documented, including age, gender, and smoking history. Additionally, detailed clinical parameters, such as the location and size of the lesions, airway grades (ranging from 0 to 24) that the PPLs located, location time of OCT and the number of specimens, were systematically recorded. investigators also conducted extensive follow-up to track histopathological outcomes, whether from surgical biopsies, CT-guided percutaneous transthoracic needle biopsies, or other diagnostic avenues, including chest CT performed two months post-procedure. All the patients were followed up by telephone or outpatient service on the 1st and 3rd day after the procedure, and adverse events were recorded. All individuals underwent general anesthesia and were fitted with a laryngeal mask.
Researchers aim to investigate whether individualized preoperative education for patients is beneficial in reducing perioperative anxiety, promoting postoperative recovery, and enhancing postoperative quality of life. The educational content will cover aspects such as the surgery procedure, anesthesia, postoperative pain and anxiety management, recovery time, and any potential required treatments. All participants will be administered a questionnaire before the surgery to evaluate their specific concerns and fears. The intervention group will receive preoperative education through audio-visual materials followed by targeted preoperative counseling, while the control group will receive routine preoperative education.
This study wants to understand the incidence of returning to work after discharge in patients with type B aortic dissection.
CAIS-MT is a single-center, prospective cohort study, to evaluate the correlation between outcomes of endovascular treatment(EVT) and intracranial artery calcification(IAC) in patients with acute ischemic stroke due to large or medium vessel occlusion.
This study proposes to analyze the burnout, emotional states, and sleep conditions of internal medicine doctors at the Second Affiliated Hospital of Zhejiang University School of Medicine through a questionnaire survey. The findings aim to provide reference for implementing measures to address burnout among medical staff, improve their physical and mental health, and enhance the quality of healthcare.
Melasma is a prevalent chronic facial pigmentation condition affecting Asian women of childbearing age, attributed to genetic predisposition, sunlight exposure, and hormonal changes. Treatment methods include phototherapy and medication, notably tranexamic acid, which inhibits melanin production. Ultra-pulsed shockwave therapy is a non-invasive approach that boosts skin cell vitality and collagen synthesis. Currently, there is a lack of comprehensive research on the effectiveness and safety of using ultra-pulsed shockwaves to deliver tranexamic acid for melasma treatment. This study will involve a non-randomized, self-half-face, pre-post controlled prospective clinical trial. This design aims to evaluate the depigmenting effects and safety profile of tranexamic acid delivered via ultra-pulsed shockwaves.
