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.
Chronic Rhinosinusitis (CRS) is a common and frequent disease in otorhinolaryngology. The main symptoms of patients include nasal congestion, runny nose, swelling pain of the frontal area and decreased sense of smell. Chronic rhinosinusitis refers to chronic rhinosinusitis with symptoms lasting ≥12 weeks and can be divided into two subgroups: chronic rhinosinusitis with and without nasal polyps. Chronic rhinosinusitis has a complex pathogenesis, there are three main pathogenic factors: infection, allergy and nasal and sinus anatomic abnormalities, these factors are often not a single existence, but often intertwined. In addition, environmental factors, genetic factors, osteitis, gastroesophageal reflux disease, respiratory ciliary system defects, systemic immune dysfunction and other secondary risk factors. For patients with chronic sinusitis, these symptoms, such as nasal congestion, runny nose, swelling pain and decreased sense of smell, often seriously affect their quality of life, and even evolve into more serious complications as the disease progresses. At present, the conventional treatment methods mainly include drug conservative treatment and nasal endoscopic surgery. Functional nasal endoscopic sinus surgery (FESS) is the main method of further surgical treatment for patients with no obvious effect of drug treatment. In FESS, the current emphasis is on removing diseased tissue and restoring sinus drainage on the premise of preserving the normal mucosa and physiological structure of the nasal and nasal sinuses as much as possible. Up to now, there have been many studies on surgical treatment of CRS, and the quality of the studies varies. However, in view of the postoperative efficacy and long-term prognosis of different subtypes of CRS, different treatment methods during surgery and different drug therapy regimens, our research group believes that it is necessary to accumulate a large amount of clinical data support through in-depth research and comprehensive analysis. Thus more reliable conclusions can be drawn. In this study, patients undergoing CRS surgery in the research ward of the Department of rhinosinusitis will be actively included through a prospective single-center cohort study to provide evidence for evidence-based medicine and better guide clinical rhinologists to make surgical treatment decisions for patients with chronic rhinosinusitis.
This study mainly aims to prospectively evaluate the changes of reactive astrogliosis in Parkinsonism patients of Chinese population by the novel 18F-labeled MAO-B PET tracer.
This is a multicenter, randomized, parallel, controlled clinical study of patients at different ages underwent elective non-cardiac surgery under general anesthesia. The aim of this study is to explore the dose range of remimazolam besylate for patients at different ages, to provide guidance for anesthesia induction and maintenance of remimazolam besylate. And to investigate the incidence of perioperative hypotension and postoperative related organ dysfunction in patients received total intravenous anesthesia with remimazolam besylate, compared with propofol.
In this study, investigators intend to prospectively study treatment-naive AA patients (including SAA and NSAA) who are non-transplant candidates in northern China. Patients with SAA receive ATG+CsA+Herombopag, and patients with NSAA receive CsA+ Herombopag. Investigators explored possible indicators of participants' predictive efficacy and built predictive models. After the participants achieved response, they used a tapering regimen, observed relapse and clonal evolution, and developed a predictive model of relapse.
Previous studies confirmed locally advanced oral/oropharyngeal squamous cell carcinoma (LA OSCC or OPSCC) patients with a pathological response had higher probability of survival in neoadjuvant settings. Several ongoing trials of neoadjuvant immunotherapy in head and neck cancer showed promising results. However, the optimal regimen remains unclear. This trial aimed to evaluate the efficacy and safety of neoadjuvant therapy with anti-programmed cell death 1 monoclonal antibody Tislelizumab and chemotherapy, followed by surgery and adjuvant radiotherapy or chemoradiotherapy plus Tislelizumab in LA OSCC or OPSCC.
The goal of this clinical trial is to evaluate the efficacy and safety of Cadonilimab(AK104) combined with Nab -Paclitaxel as first line therapy for recurrent or metastatic muscle invasive bladder. Eligible participants will receive AK104 (up to 24 months) plus Nab-Paclitaxel (for 6 cycles) until radiologic disease progression, unacceptable toxicity, or withdrawal from the study, whichever occurred first. The primary endpoint is objective response rate.
This study is an open, single center clinical study targeting solid tumor patients who have exhausted or cannot tolerate standard treatment regimens. The main purpose of this study is to investigate the feasibility, efficacy, and safety of selecting treatment regimens based on DOTr/DOTa results for solid tumor patients who have exhausted or cannot tolerate standard treatment regimens.
The diagnosis of depressed left ventricular ejection fraction (dLVEF) (EF<50%) depends on golden standard ultrasound cardiography (UCG). A wearable synchronized phonocardiography (PCG) and electrocardiogram (ECG) device can assist in the diagnosis of dLVEF, which can both expedite access to life-saving therapies and reduce the need for costly testing.
This trial aims to assess efficacy and safety of toripalimab combined with radiotherapy and S-1 followed by adjuvant toripalimab maintenance therapy for older patients with stage II-III esophageal cancer.
A multicenter, prospective, open, randomized cohort, non controlled phase II clinical study to evaluate the effectiveness and safety of Darxil combined with Exemestane+goserelin neoadjuvant endocrine therapy in HR positive and HER2 negative premenopausal breast cancer patients. The study object was to evaluate the HR positive and HER2 negative premenopausal breast cancer patients with SD after 2 cycles of neoadjuvant chemotherapy. The main endpoint was the objective response rate (ORR) of treatment
