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.
Over the last 20 years, extracorporeal membrane oxygenation (ECMO) has been used to support adult patients with respiratory or cardiac failure who are unlikely to survive conventional treatment methods. ECMO circuit, pump, and oxygenator technology improvements permit safer perfusion for extended periods. The prolonged use of an ECMO circuit increases the risk of membrane lung (ML) dysfunction. The ML is responsible for taking in oxygen and removing carbon dioxide. The non-biologic surface of the ML triggers inflammatory and coagulation pathways, resulting in the formation of blood clots, breakdown of fibrin, and activation of white blood cells, which ultimately leads to ML dysfunction. Coagulation and fibrinolysis activation can cause systemic coagulopathy or hemolysis, and the deposition of blood clots can block blood flow. Moreover, the accumulation of moisture in the gas phase and the buildup of protein and cellular debris in the blood phase may contribute to shunt and dead-space physiology, respectively, impairing the exchange of gases. These three categories-hematologic abnormalities, mechanical obstruction, and inadequate gas exchange-account for most ML exchanges. Worsening oxygenation during ECMO should prompt quantification of oxygen transfer. ML exchange is indicated when the ML can no longer meet the patient's oxygen demand. The partial pressure of Post-ML arterial oxygen less than 200 mmHg is the most important consideration in this decision. In some high-altitude regions of China, ECMO treatment is also routinely conducted. The experiences above are derived from low-altitude areas, and whether they apply in high-altitude regions is still being determined. This study aimed to explore the significantly lower membrane lung oxygen uptake in high-altitude regions compared to low-altitude areas.
Hypothesis of "AN-ACC pathological network" suggests that ACC overactivation and abnormal functional connectivity with other brain regions is the neuropathological mechanism for the onset of AN. Currently, rare studies have been conducted on dTMS targeting ACC as an intervention in patients with AN. In this research, dTMS, a neuroregulatory technology, is used for the first time to intervene with ACC in the treatment of adult AN. A randomized controlled study design is adopted, in which patients with AN are divided into the dTMS treatment group and the pseudo-stimulation group by 1:1 randomization, followed by 6-week intervention and half-year follow up, to clarify the near-term and long-term efficacy and safety of the dTMS treatment. Meanwhile, baseline fMRI data will be extracted and combined with clinical features to establish an efficacy prediction model, which will provide theoretical and practical basis for the pioneering ACC-targeted dTMS treatment in China, helping to establish a new type of intervention program for AN, with expected results of innovation.
Comparison of corneal topography based on oct OCT principle (CASIA2) with Pentacam and Scheimpflug-based biomechanical devices (Corvis ST) in screening and diagnosing keratoconus; and evaluation of the consistency with Pentacam in measuring corneal parameters (such as curvature and thickness).
Color change is a useful marker for the endoscopic identification of chronic atrophic gastritis (CAG) and gastric cancer (GC). Several histopathological studies have suggested a correlation between certain gastrointestinal lesions and intramucosal vascularity. The aim of this study is to investigate the association between the color and mucosal microvascular density of CAG and early GC using linked color imaging (LCI). In this study, Lesions diagnosed as CAG and early GC will be observed using LCI. In each image, the color values of atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be quantified using the International Commission on Illumination 1976 (L∗, a∗, b∗) color space. Histological microvascular density in biopsy or resected specimens will be evaluated using CD31 immunostaining. Color differences at the atrophic border and cancerous border, defined as Euclidean distances of color values between the atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be calculated according to mucosal microvascular density.
The purpose of this clinical trial is to evaluate the efficacy and safety of immunotherapy combined with cetuximab and platinum neoadjuvant therapy in patients with resectable locally advanced hypopharyngeal cancer. Participants will receive three cycles of TPC neoadjuvant therapy (toripalimab+ cetuximab + platinum), radical surgery (laryngeal preservation surgery if possible), and sequential (chemo)radiotherapy treatment after surgery. This trial aims to answer the following questions: 1. pCR rate 2. MPR rate, ORR, LPR/DFS/OS rare at 1 and 2 years 3. Safety and quality of life
Efficacy and Safety Study of QLM3004 in Myopic Children
This study is open to adults 18 years and older with advanced or metastatic non-small cell lung cancer. People can join the study if they have tumours with HER2 mutations and have not yet received any systemic therapy including chemotherapy for advanced or metastatic lung cancer. The purpose of this study is to find out whether a medicine called zongertinib (BI 1810631) can slow down the worsening of advanced non-small cell lung cancer better than the standard treatment available. Zongertinib may slow cancer cell growth by inhibiting HER2. This would prolong cancer re-occurrence and increase survival. Current standard treatment is pembrolizumab plus platinum-pemetrexed chemotherapy. Participants are put into 2 groups by chance. One group receives zongertinib at regular times throughout the study and the other group receives infusions of pembrolizumab, pemetrexed and cisplatin or carboplatin (pembrolizumab plus platinum-pemetrexed chemotherapy) into a vein. Participants may be in the study up to a maximum of 70 months. During this time, they visit the study site about every 3 weeks for study procedures. The doctors regularly check the size of the tumour with a CT or MRI scan, at the beginning of the study and every 6 weeks. After 18 months they check the tumour size every 12 weeks. Doctors regularly check whether the cancer has spread to other parts of the body. The doctors also regularly check participants' health and take note of any unwanted effects. The time it takes for the cancer to worsen is compared between the 2 groups to see whether the treatment works. The participants also fill in questionnaires about their symptoms and quality of life.
