Clinical trials

Magnifying endoscopy provides high-resolution images that enhance the detection of early gastrointestinal lesions. However, conventional manual zoom techniques require frequent focal adjustments, which can be technically demanding and may compromise image stability, especially in complex anatomical settings. This study evaluates a novel one-click autofocus system based on image recognition and computer vision algorithms. The system automatically adjusts focal distance within seconds, eliminating the need for manual operation. This trial aims to compare the efficiency and image quality of one-click autofocus versus segmented manual focus in patients undergoing magnifying endoscopy for gastric diseases. A tandem randomized controlled trial will be conducted to assess procedure time, image clarity score, and operator satisfaction between the two techniques.

The PAOLA-1 trial demonstrated that for HRD-positive patients who received first-line chemotherapy combined with bevacizumab, sequential maintenance therapy with olaparib plus bevacizumab yielded a progression-free survival (PFS) of up to 46.8 months, with an olaparib-related treatment discontinuation rate of approximately 20%. The combination of olaparib and bevacizumab has been recommended by multiple clinical guidelines as the first-line maintenance regimen for HRD-positive patients treated with first-line chemotherapy plus bevacizumab. This regimen has obtained approved indications and been covered by national medical insurance. In clinical practice, around 30% of patients receiving chemotherapy plus bevacizumab adopt olaparib combined with bevacizumab for first-line maintenance treatment. Fluzoparib has been approved in China for first-line maintenance therapy in the overall patient population. The treatment discontinuation rate of fluzoparib plus apatinib is merely about 2%. However, there is currently no available data regarding fluzoparib combined with bevacizumab in the HRD-positive population, and the clinical value of this regimen remains to be further explored. This study aims to generate efficacy and safety data for olaparib plus bevacizumab versus fluzoparib plus bevacizumab in HRD-positive patients who have undergone first-line chemotherapy combined with bevacizumab, so as to provide objective evidence for clinical medication decisions.

The goal of this clinical trial is to investigate if Shouhui Tongbian Capsules can shorten intestinal function recovery time (exhaust/defecation time) and improve defecation quality in perioperative patients, and to evaluate its safety and comfort advantages during the perioperative period. The study involves participants aged 18-70 years, both male and female, with ASA grade I-III scheduled for elective surgery. The main questions it aims to answer are: Can Shouhui Tongbian Capsules shorten the intestinal function recovery time (first flatus and defecation time) in perioperative patients? Can Shouhui Tongbian Capsules improve defecation quality (assessed by Bristol Stool Scale) and reduce inflammatory factor levels (e.g., IL-6, TNF-α)? Researchers will compare the experimental group (receiving Shouhui Tongbian Capsules 2 pills twice daily from admission to the night before surgery, then resuming after bowel sound recovery and oral intake postoperatively, with a 3-day post-discharge regimen) to the control group (receiving routine perioperative care including diet control and standard bowel-cleansing drugs) to see if the capsules show superior efficacy in intestinal function recovery and safety. Participants will: Take Shouhui Tongbian Capsules according to the specified regimen (experimental group) or receive routine care (control group). Have their exhaust/defecation status recorded every 6 hours postoperatively. Undergo blood tests for liver/kidney function and inflammatory factors on the day before surgery and day 3 postoperatively.

Complete clinical assessments (TSSS scoring) and mycological examinations (microscopy/culture) at baseline and follow-up visits. Undergo routine laboratory tests (liver/kidney function, hematology) to monitor safety.

The objective of this study is to investigate the role of the flexible auxiliary single-arm transluminal endoscopic robot (FASTER) system in colorectal endoscopic submucosal dissection (ESD) and to validate its superiority over conventional ESD in terms of reducing procedural difficulty, shortening procedure time, and enhancing procedural safety. The main questions it aims to answer are: Does the use of the FASTER system improve the dissection speed of the ESD procedure? Does the use of the FASTER system reduce the procedure and dissection time, improving the efficacy of the ESD procedure? Does the use of the FASTER system reduce the rate of perforation and hemorrhage, improving the safety of the ESD procedure? Researchers will compare FASTER-assisted ESD and conventional ESD to evaluate the safety and efficacy of the FASTER system. Participants will: Be randomly assigned to the group with ESD using the traditional procedure or to the group with ESD assisted by the FASTER system. Keep a diary of their symptoms after the procedure. ESD has gained widespread acceptance as the standard method for treating early-stage gastrointestinal cancers. However, ESD is a technically demanding and intricate procedure that requires advanced proficiency of operators, with a heightened risk of complications such as hemorrhage and perforation. The inherent challenges of the colorectal ESD are further amplified by the thin mucosa, highly tortuous and flexible lumen, and occasional obstruction of lesions by mucosal folds, all of which collectively elevate both the procedural difficulty and the probability of postoperative complications. Adequate exposure of the submucosa layer through effective tissue traction is vital for the safe and effective performance of ESD. The FASTER system is designed to overcome this technical difficulty.

Pneumonia is characterized by high incidence and mortality rates in elderly patients (≥65 years old). Piperacillin-tazobactam, as a broad-spectrum antibiotic, has its therapeutic efficacy and safety potentially influenced by the infusion regimen. However, research on infusion regimens specifically targeting the elderly population is currently limited. In our preliminary dose simulation, under the pharmacokinetic/pharmacodynamic (PK/PD) target of achieving a free drug concentration time percentage above 100% of the minimum inhibitory concentration (fT%\>100% MIC), the regimen of administering the drug every 6 hours (q6h) achieved a concentration compliance rate of 90% within 4 hours. This study aims to explore the differences between two infusion modes (q6h for 4 hours vs. q8h for 3 hours) and to provide preliminary evidence for clinical practice.

Detection and removal of polyps during colonoscopy is crucial for the prevention of colorectal cancer. Indigo carmine spraying up to the colonic mucosa could probably increase the adenoma detection rate, but considering the long withdrawal time of the endoscope and the resulting increase in time and cost. Linked-color imaging (LCI) is a newly developed image-enhanced endoscopy technology. It relies on wave length optimization of three colors (red, green, and blue) to make the lesions appear fuller. LCI improves the visibility of colorectal adenomas and polyps and may increase the detection rate of lesions. In order to explore the clinical application value of Linked-color imaging endoscopy, we performed a prospective, randomized controlled trial to compare adenoma detection rate of Linked-color imaging endoscopy and indigo carmine chromoendoscopy.

RATIONALE: Talniflumate, a prodrug of niflumic acid with significant anti-inflammatory properties, has emerged as a promising candidate in breast cancer therapy due to its ability to modulate key oncogenic pathways. Its mechanisms of action include the inhibition of cyclooxygenase (COX) enzymes, which mitigates tumor-promoting inflammation and fosters a less permissive microenvironment for cancer progression. Additionally, talniflumate disrupts ionic homeostasis by targeting calcium-activated chloride channels (CaCCs), leading to impaired cellular proliferation and potential induction of apoptosis. The agent also exhibits anti-angiogenic activity by downregulating vascular endothelial growth factor (VEGF), thereby restricting tumor vascularization and growth. Furthermore, talniflumate shows potential as a chemosensitizer, enhancing the cytotoxic effects of standard chemotherapy and improving therapeutic outcomes while reducing chemoresistance. These multifaceted mechanisms highlight the therapeutic promise of talniflumate in breast cancer, warranting further preclinical and clinical studies to validate its efficacy, refine dosing strategies, and define its role in combination therapies. PURPOSE: To assess the therapeutic efficacy of Talniflumate in the management of breast cancer, with a focus on its synergistic interactions with neoadjuvant chemotherapy.

The study aimed to compare the efficacy and safety of dual and quadruple regimens with different durations (7-day, 10-day, 14-day) for the eradication of Helicobacter pylori. Subjects were randomized to receive the intervention and were reviewed by 13C-urea breath test after 6 weeks. The eradication rates, adverse reaction rates and patient adherence were calculated.

Abdominal distention represents a prevalent clinical manifestation characterized by an unclear etiology and pathogenesis. This symptomatology is frequently observed in various conditions, including small intestinal bacterial overgrowth (SIBO) and abnormal orocecal transit time (OCTT). The utilization of the breath test as a non-invasive diagnostic approach has become widespread in recent years for identifying SIBO and abnormalities in OCTT. In this study, the prevalence of SIBO and OCTT irregularities in individuals presenting with abdominal distention was ascertained through the implementation of the breath test. Furthermore, the correlation between abdominal distention and SIBO/OCTT was analysed to enhance the elucidation of the underlying etiology of abdominal distention. These findings aim to offer valuable insights for refining clinical comprehension and strategies related to the diagnosis and treatment of abdominal distention.
