Assess the sensitivity, specificity, positive predictive value, and negative predictive value of dynamic monitoring of circulating tumor DNA (ctDNA) combined with circulating HPV DNA (cfHPV DNA) for early prediction of recurrence in cervical cancer post-surgery or post-treatment, and compare its advantages and disadvantages with existing diagnostic methods.
Hyperuricemia is a major risk factor for many chronic diesease. Recently, gut mcirobiota has been identified as a novel theraputic target for hyperuricemia. Both annimal studies and pilot human trials have demonstrated that administration of prebiotics help delay the progression of hyperuricemia throuh several mechanisms. This trial aims to examine its protective effects and potential mechanisms in clinical trials.
To compare the efficacy and safety of intratracheal deep intubation with traditional intubation in endoscopic submucosal dissection for early esophageal cancer in the cervical esophagus, and to follow up and assess their short-term clinical outcomes.
This study aims to investigate the effects of Chinese herbal granule preparations on improving gastrointestinal symptoms in patients after bariatric surgery. It seeks to establish a novel treatment model that combines bariatric surgery with traditional Chinese medicine, providing clinical practice with additional evidence-based medical support.
A Translational Study to Describe Asthma Patient Clinical Characteristics, Treatment Patterns, Biomarkers and to Identify Phenotypes and Endotypes associated with Differential Outcomes that may Support Future Development of Personalised Treatment Strategies in Chinese Population
99mTc-QULIC-5-P1 is a new radiotracer targeting PSMA, which is promising as an excellent imaging agent applicable to PSMA positive prostate cancer. This study will investigate the safety, biodistribution and potential usefulness of 99mTc-QULIC-5-P1 SPECT imaging for the diagnosis of lesions in PSMA positive prostate cancer.
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.
