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 is a pilot study to evaluate the efficacy and safety of Tacrolimus Sustained-release Capsules (ADVAGRAF) for the induction therapy of Lupus Nephritis (LN) (V, III +V, IV+V).
Acute hypoxaemic respiratory failure (AHRF) refers to pathological states in which arterial blood oxygenation is severely impaired，and which need invasive positive pressure ventilation (IPPV) as respiratory support technique in most cases.However，IPPV carries well-known risks of complications such as ventilator induced lung injury (VILI) or ventilator associated pneumonia (VAP)，and the incidence of which is increased as the prolongation of IPPV so as to lead to higher mortality rate. Consequently，early extubation is extraordinarily necessary. More recently, NPPV has shown to shorten the duration of IPPV，reduce the mortality and morbidity rates in patients with chronic obstructive pulmonary disease (COPD). Despite this evidence, the efficacy of NPPV in patients with AHRF has not been evidenced. However，NPPV has been shown to provide adequate ventilation and oxygenation，and reduce inspiratory muscle effort，neuromuscular drive，and dyspnea scores. Moreover，to some patints，NPPV is similar with IPPV in providing oxygenation. The duration of weaning is from the first day a patient met standard criteria for weaning readiness to the time of successful extubation (lasting at least 48 h)，which represents 40-50% of the total duration of IPPV.As a result，duration of IPPV would be shortened if that of weaning was shortened. The investigators hypothesized that in mechanical ventilated patients with AHRF who met standard criteria for weaning readiness and suffer failure of spontaneous breathing trial, use of NPPV for early extubation, providing adequate ventilation and oxygenation, would shorten the duration of IPPV as the primary end-point variable, thereby reduce the incidence of complication and mortality rates. Accordingly, the investigators conducted a prospective，randomized clinical trial to assess the efficacy of this strategy compared with the conventional-weaning approach.
Empirical implantation of the left ventricular lead is the prevailing practice in cardiac resynchronization therapy device implantation. The response rate to the therapy has been uniformly 70% only despite various methods to screen patients before device implantation. This study tested the hypothesis that echocardiography to assess acute resynchronization of the left ventricle during device implantation may improve the response rate to the therapy.
Nimotuzumab (hR3) is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Clinical efficacy has been shown in adult with head and neck cancer. The study assessed the safety, and efficacy of the combination of Nimotuzumab administered concomitantly with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC).
A prospective, randomized, open-label, stratified, controlled clinical trial to evaluate whether long term furosemide therapy (1 year) would preserve urine volume and/or residual renal function (RRF) and improve fluid state in continuous ambulatory peritoneal dialysis (CAPD) patients.
Hypothesis: there is a high prevalence rate of diabetes, including asymptomatic undiagnosed glucose intolerance, among subjects with coronary heart disease in Hong Kong. A cross-sectional survey is planned to study the rate of undiagnosed diabetes and glucose intolerance among the Chinese patients with coronary heart disease in Hong Kong. The survey results will be important for us to plan the logistics to investigate and manage the potential glucose abnormality of our heart disease patient.
The purpose of this study is to determine whether the occurrence of idiopathic right ventricular outflow tract(RVOT) arrhythmia is relative to sex hormone levels in different stages of female menstrual cycle
The purpose of this study is to understand how severe acute respiratory syndrome (SARS) spreads within families, if significant disease resulted, and how the body responds to SARS. The study will also explore the affects of SARS on genetics and the immune system (the body system that fights disease). Up to 1000 people residing in Beijing, China may be involved in this study. Adult survivors of SARS (numbering 200) and their family members including children age 4 and up will be asked to participate in the study. The study will recruit an additional 200 persons, who will be matched with SARs survivors of similar age, gender, health status, and housing/work location, and recruited as comparators. Blood will be taken from all volunteers and tested for the presence of SARS antibodies (proteins made by the body's immune system in response to something that can cause infection). Health and clinic/hospital visit records may be reviewed.
The purpose of this study is to determine the efficacy and safety of Betahistine Mesilate in the treatment of patients with vertigo caused by Cerebral Infarction in posterior circulation.
This study seeks to test the Efficacy in terms of rates of disease response in metastatic nasopharyngeal carcinoma of the standard dose of velcade 1.3 mg/m2 given at the day 1,4,8,and 11 every 21 days schedule. The study uses a Simons 2 stage design and will enroll between 15-25 patients. Secondary endpoints studied include Pharmacokinetics, toxicities, EBV viral load and molecular characterization of EBV in plasma.
