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.
To verify the role of apatinib in neoadjuvant therapy for breast cancer, the investigators designed a prospective, randomized, parallel-controlled phase II/III trial, to investigate the efficacy and safety of apatinib combined with TP (paclitaxel + cisplatin) or TP regimen alone as neoadjuvant therapy for stage II-III breast cancer treatment. 100 cases of eligible patients were diagnosed by core needle biopsy and immunohistochemistry, with the molecular subtypes of triple-negative, HER2+ or Luminal B, evaluated by pathological complete remission (pCR), objective response rate (ORR), adverse events, disease free survival (DFS) and OS, aiming at providing a new way for neoadjuvant therapy in breast cancer and anti-angiogenic treatment of malignant tumors.
The objective of this study is to assess the efficacy and safety of upadacitinib combined with topical corticosteroids (TCS) for the treatment of adolescent and adult participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
This study is to evaluate the safety and efficacy of Umbilical Cord Derived Mesenchymal Stem Cells transplantation in Parkinson's disease.
A cross-sectional study was performed from 2017 to 2018. Consecutive Crohn's disease patients diagnosed in the Inflammatory bowel disease center of the Sixth Affiliated Hospital of Sun Yat-sen University were recruited. All patients underwent upper gastrointestinal endoscopy and biopsy by two defined endoscopists and two pathologists, the basic information were collected at the same time, in order to assess the prevalence of upper gastrointestinal involvement, and determine the role of upper gastrointestinal endoscopy in adult Crohn's disease patients, irrespective of upper gastrointestinal symptoms.
Children scheduled for tonsillectomy surgery were recruited into the study. General anesthesia was induced with 8% sevoflurane inhaled with 8 l.min-1 of oxygen via mask, followed by adjustment of inspired sevoflurane to the target concentration based on the result in previous patient at which laryngoscopy and tracheal intubation were attempted and maintained for 12 min. All responses to tracheal intubation were assessed. At the end of the procedure, sevoflurane was titrated to the target concentration, which was kept constant for 12 min before a standard stimulus was applied to determine whether the children was awake. The Dixon's 'up and down'method was used to determine progression of subsequent concentrations.The aim of this study was to determine whether the minimum alveolar concentration of endotracheal intubation(MACEI)of sevoflurane in children with obstructive airway are different from that observed in normal children.
In 1894, Devic first proposed the concept of neuromyelitis optica(NMO). NMO is an inflammatory demyelinating disease that selectively affects the central nervous system of the optic nerve and spinal cord.In 2004, Lennon and other persons found highly specific AQP4(aquaporin 4)antibodies in NMO patients'sera, and further differentiated between NMO and MS, confirming that NMO is an independent disease.At present, NMO has been widely recognized as an idiopathic and severe demyelinating disease of the central nervous system.In 2015, the international NMO diagnostic team developed the diagnostic criteria based on highly specific AQP4 antibodie.Up to now, in China, there is no data on the number of NMOSD patients, the rate of misdiagnosis, the treatment methods, and the prognosis.This study is committed to build China's NMOSD big data platform to provide the basis for diagnosis, treatment and prognosis of the disease.
Large amounts of experimental and animal evidence have confirmed that iron accumulation is associated with bone loss. However, it is still lack of the clinical studies relating iron accumulation to bone loss, especially in the pathological conditions during our Chinese. In this study, the investigators aim to assess the association between the levels of serum ferritin and bone mineral density in Chinese healthy postmenopausal women.
EAST-STEMI is the first perspective, multicenter, large-scale registry focusing on the evaluation of real-world medical quality (especially PCI quality) and antithrombotic strategies in STEMI patients undergoing emergent PCI in a regional representative sample in China with 2 years follow-up. Clinical decision support tools (including ischemic score, bleeding score, etc) will be developed and validated based on the database. Novel biomarkers to predict the prognosis and to support risk stratification will be explored by using the blood samples.
Intracranial pressure(ICP) increases during laparoscopic gynecologic surgery increase (ICP) and may alter optic nerve sheath diameter(ONSD).This study measures ONSD in different team because sevoflurane and propofol have different effects on ICP.Half of participants will receive sevoflurane anesthesia,while the other half undergo propofol anesthesia.
This study is a prospective, multicenter, cohort study. The study will be completed in three phases. The first phase aims to establish SCD PW marker and PW score scoring system 1. Use big data processing techniques to find out the differences between survivors with ventricular arrhythmias and normal controls. Find out the SCD Pre-warning ECG Marker (PW marker). 2. Establish SCD Pre-warning risk score system according to traditional SCD risk factors, clinical characteristics of patients and abnormal electrocardiogram indicators. 3. According to the established SCD PW marker and PW score scoring system, the original group of patients are classified and scored. After five years of follow-up with sustained ventricular tachycardia or ventricular fibrillation as the primary end point and sudden cardiac death as the secondary endpoint, Kaplan-Meier are used to calculate the mortality rate of sudden cardiac death and Kaplan-Meier survival analysis. The COX proportional hazards regression model is used to further determine and evaluate the SCD predictive value of PW marker and PW score risk factor scoring system. The second phase is to validate the established PW marker and PW score system models and evaluate the SCD predictive value of it. This stage is divided into two parts: 1. Patients enrolled in traditional high-risk ventricular arrhythmia, will be divided into PW marker positive group and PW marker negative group and join in a 5-year follow-up. Kaplan-Meier is used to calculate the mortality rate of sudden cardiac death and Kaplan-Meier survival analysis is performed to further verify the early warning effect of PW marker on SCD. 2. Patients will be divide into three groups including the low-risk group, middle-risk group and high-risk group according to the PW score risk factor scoring system and join in a 5-year follow-up. Kaplan-Meier is used to calculate the mortality rate of sudden cardiac death, and Kaplan-Meier survival analysis is used to further verify the early warning effect of PW score scoring system on SCD. The third stage is the development stage of SCD early warning equipment. This stage will conduct clinical translational medical studies of PW marker and PW score based on the previous study and develop PW marker and PW score as portable SCD warning device and/or mobile phone APP which will be applied to the clinic for early warning diagnosis of SCD.
