There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study is a prospective cohort study to evaluate the peripheral blood lymphocyte subsets as predicative biomarkers reflecting the efficacy and toxicity in patients with locally advanced non-small cell lung cancer (NSCLC) received chemoradiotherapy (CRT) with or without immune checkpoint inhibitors (ICIs).
Sedatives and analgesics are usually given for analgesic, anxiolytic, or sedating purposes for patients with critical illness, while they inevitably inhibit respiratory and circulatory function. Sometimes, patients receive deep sedation to induce hypoventilation or suppress spontaneous respiratory effort. The sedation level in clinical practice is usually assessed with subjective sedation scoring systems, such as the Richmond Agitation Sedation Scale (RASS). However, studies have found that sedation depth based on RASS is not a reliable marker of respiratory drive during critical illness. In recent years, researchers have proposed to monitor the effects of sedatives and analgesics on respiratory indicators and to implement lung-protective sedation, such as P0.1, Pocc, Pmus, WOB, and PTP. However, different pharmacological characteristics, different depths of sedation, and different sedation regimens among different sedatives and analgesics make a great difference in their effects on respiration. Ciprofol is an analog of propofol, with increased stereoselective effects adding to its anesthetic properties, is increasingly used in the intensive care unit, but its effects on respiration are not well understood. Therefore, this study aims to investigate the effects of ciprofol on respiratory patterns, respiratory drive, and inspiratory effort in mechanically ventilated patients.
It is imperative to offer adequate community resources and psychosocial support, with a particular focus on enhancing resilience for children from low-income families. This study aims to determine the feasibility, acceptability, and preliminary efficacy of mountain craft training in enhancing resilience and self-esteem, reducing depressive symptoms, and improving the physical health of children from low-income families.
The incidence of papillary thyroid cancer (PTC) has been on the rise in recent years, and 20%-50% of PTC patients will have lymph node metastasis. Lymph node involvement in PTC patients is usually related to the recurrence of PTC after surgery, and 30% of patients recur without lymph node dissection, with the risk of central cervical lymph node metastasis being the greatest, so it seems to be a good choice to perform lymph node dissection on patients after thyroidectomy, but in fact, there are controversies at home and abroad as to whether to perform lymph node dissection or not. The 2021 Chinese Society of Clinical Oncology (CSCO) guidelines for the diagnosis and treatment of differentiated thyroid cancer state that prophylactic central lymph node dissection (PCND) may increase the incidence of postoperative complications, but due to the high metastatic rate of PTC and the ability of PCND to effectively prevent recurrence and reoperation, countries in the East Asian region perform prophylactic lymph node dissection on almost all patients with PTC. However, for more countries in Europe and the United States, performing PCND has become a non-essential, individualized option. The aim of this study is to collect multifactorial data from more than 1,000 patients who have undergone previous thyroidectomy from 2021 to 2023, and to develop a novel scoring scale that can be used to individualize patients' scores based on a variety of factors prior to surgery, so that patients can be more accurately predicted to have lymph node metastasis and need prophylactic lymph node dissection prior to surgery, and patients who do not need dissection can avoid surgery. For patients who do not need lymph node dissection, complications caused by surgery can be avoided, while for patients who do have lymph node metastasis, recurrence of their cancer can be prevented. This will change the status quo of not being able to accurately determine the actual situation through simple preoperative examination or performing prophylactic lymph node dissection for all PTC patients.
By utilizing standardized photographs in conjunction with quantification detection instruments, data analysis before and after treatment is conducted, along with long-term efficacy observations. This approach aims to provide more comprehensive scientific evidence for the clinical application of ultrasound treatment in anti-aging therapy.
Breast phyllodes tumor (PT) is a rare fibroepithelial tumor, accounting for 1% to 3% of all breast tumors, categorized by the WHO into benign, borderline, and malignant, based on histopathology features such as tumor border, stromal cellularity, stromal atypia, mitotic activity and stromal overgrowth. Malignant PTs account for 18%-25%, with high local recurrence (up to 65%) and distant metastasis rates (16%-25%). Benign PT could progress to malignancy after multiple recurrences. Therefore, Early, accurate diagnosis and identification of therapeutic targets are crucial for improving outcomes and survival rates. In recent years, there has been growing interest in the application of artificial intelligence (AI) in medical diagnostics. AI can integrate clinical information, histopathological images, and multi-omics data to assist in pathological and clinical diagnosis, prognosis prediction, and molecular profiling.AI has shown promising results in various areas, including the diagnosis of different cancers such as colorectal cancer, breast cancer, and prostate cancer. However, PT differs from breast cancer in diagnosis and treatment approach. Therefore, establishing an AI-based system for the precise diagnosis and prognosis assessment of PT is crucial for personalized medicine. The research team, led by Dr. Nie Yan, is one of the few in Guangdong Province and even nationally, specializing in PT research. Their team has been conducting research on the malignant progression, metastasis mechanisms, and molecular markers for PT. The team has identified key mechanisms, such as fibroblast-to-myofibroblast differentiation, and the role of tumor-associated macrophages in promoting this differentiation. They have also identified molecular markers, including miR-21, α-SMA, CCL18, and CCL5, which are more accurate in predicting tumor recurrence risk compared to traditional histopathological grading. The project has collected high-quality data from nearly a thousand breast PT patients, including imaging, histopathology, and survival data, and has performed transcriptome gene sequencing on tissue samples. They aim to build a comprehensive multi-omics database for breast PT and create an AI-based model for early diagnosis and prognosis prediction. This research has the potential to improve the diagnosis and treatment of breast PT, address the disparities in breast PT care across different regions in China, and contribute to the development of new therapeutic targets.
Robotic surgical systems have become a promising surgical assistance system, with unique advantages such as 3D high-definition visual system, highly flexible wrist-jointed instruments, and automatic fitering of hand tremors. Robotic surgical systems is applied in various fields including urology, general surgery, cardiothoracic surgery, head and neck surgery, and gynecology. Currently, the Da Vinci surgical robot system is the most widely used robot system globally. However, the Da Vinci robot system for single-port laparoscopic surgery has not yet been launched in China. Therefore, the investigators conduct a prespective, single-center study to evaluate the efficacy and safety of single-port surgical robot system in thoracic surgery.
Postoperative gastrointestinal complications following ESD, EMR, and EFTR procedures, such as gastrointestinal bleeding, diverticula, fistulas, perforations, and stent fixation, can be effectively treated through gradual endoscopic procedures. The technical limitations of traditional endoscopic hemoclips restrict their application. Although endoscopic suturing techniques are emerging, most are still in the exploratory phase. Therefore, the investigators have developed metal-reinforced teeth for hemoclips. This initial clinical study aims to validate the safety, feasibility, and effectiveness of reinforced teeth in clinical applications. The investigators also aim to explore the uses and limitations of this technology. The primary outcomes are the technical success rate and the clinical success rate.

Participants will be transfused with fresh irradiated red blood cells, washed red blood cells, and leukocyte privative red blood cells respectively according to relevant clinical and laboratory indicators.
Radiation therapy is a common treatment modality in the management of head and neck malignancies. However, head and neck tumors often have some adverse reactions when receiving radiation therapy, such as dry mouth, change of taste, oral mucositis, etc. Among them, the incidence of oral mucositis is more than 90%, and the incidence of oral mucositis of degree 3 or more than degree 3 is more than 50%. Severe oral mucositis seriously affects the quality of survival of patients. Lactobacillus Reuteri is a natural flora of the human body that can be found in the gastrointestinal tract, skin, etc. Among them, Lactobacillus Reuteri DSM 17938 and ATCC PTA 5289 can be isolated from healthy mammals as well as poultry, and are common Lactobacillus strains marketed for the production of oral probiotics, which are commonly used in infant formulas, among others. In oral inflammatory diseases, it has been reported in the literature that Lactobacillus Reuteri DSM 17938 and ATCC PTA 5289 can reduce gingival and periodontal inflammation, mainly through the mechanisms of modulating the host inflammatory response and displacing pathogenic bacteria. In terms of safety, oral Lactobacillus Reuteri has good stability, very low pathogenic potential, and is not toxic to humans. Therefore, this study is a placebo-controlled, multi-center, open, randomized controlled clinical study to evaluate the efficacy of Lactobacillus Reuteri for the prevention of radioactive oral mucosal reactions in intensity-modulated radiotherapy for head and neck tumors, including nasopharyngeal carcinoma.
