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.
The prevalence of type 2 diabetes mellitus (T2DM) has been increasing rapidly in China. China currently has ~130 million diabetes cases, and over 90% are T2DM. T2DM is a leading cause of morbidity and mortality, posing substantial clinical and public health challenges. Reversing T2DM with a significant amount of weight loss via consuming a low-calorie diet is possible, but no studies have been conducted to determine whether low-calorie diets will help achieve significant weight loss and diabetes remission among Chinese patients with T2DM. The investigators design a pilot study to assess the feasibility of a low-calorie diet intervention program on weight loss and diabetes remission in a Chinese population with T2DM.
This study is an open-label,single center phase Ⅳ clinical trial of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine.The purpose of this study is to evaluate the safety and immunogenicity of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine in the elderly aged 60 years and above.
This phase Ib study included two parts in which Part I was to evaluate the safety and bridge for PK among healthy Chinese subjects and Part II were about study among Chinese chronic hepatitis B virus-infected patients. Study of Part II was carried out following the safety assessment and racial difference evaluation in Part I.
Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies. Bronchial asthma is associated with bronchial asthma in 40% of patients with AR, suggesting a comorbid feature of allergic disease.
The purpose of this study was to evaluate the Efficacy and Safety of Vonoprazan- amoxicillin dual therapy for Helicobacter Pylori eradication
This study is a prospective, randomized, controlled trial. In this study, 30 patients who underwent endotracheal tumor resection under rigid bronchoscope or stent placement for acquired tracheoesophageal fistula were selected as the subjects. The patients were randomly divided into remazolam general anesthesia group (R group) and propofol general anesthesia control group (P group). Remazolam general anesthesia group (R group): Remazolam 0.4 mg/kg, oxycodone 0.2 mg/kg and rocuronium 0.9 mg/kg were given for anesthesia induction. Propofol general anesthesia control group (P group): Propofol 1.5mg/kg, oxycodone 0.2mg/kg and rocuronium 0.9mg/kg were given for induction of anesthesia. After induction, high-frequency jet ventilation was used in both groups, the respiratory rate was 30-60 times/min, the inspiratory-to-breath ratio was 1:2, and the driving pressure was 0.8-1.0 KPa. Group R was given remazolam 1mg/kg/h and remifentanil 6-8ug/kg/h for maintenance. Group P was given propofol 4-8 mg/kg/h and remifentanil 6-8ug/kg/h for anesthesia maintenance. The dosage of propofol or remazolam was adjusted according to BIS and intraoperative hemodynamic changes. Rocuronium bromide 10 mg was added every half hour. Intraoperative application of vasoactive drugs to maintain mean arterial pressure above 60mmHg to avoid perioperative hypotension. Blood oxygen saturation and end-tidal carbon dioxide were monitored to avoid perioperative hypoxemia and hypercapnia, and warm measures were used to maintain the patient's intraoperative body temperature above 36.0°C. After surgery, group R was treated with sugammadex sodium 2-4 mg/kg to antagonize rocuronium bromide, and 0.5 mg of flumazenil was used to antagonize remazolam by intravenous injection; group P was treated with sugammadex 2-4 mg/kg to antagonize rocuronium.
This study is a single-center, single-dose, non-randomized, open-label study to evaluate the in vivo mass balance of [14C]Hemay005. Six healthy male subjects are planned to be enrolled.
Pulse oximetry offers real time and non-invasive estimation of arterial oxygen saturation in a cost-effective way, and has become a critical tool in guiding the usage of supplemental oxygen in sick newborns. During postnatal transition, pulmonary pressure decreases upon the activation of the lungs, and the ductus arteriosus constricts and closes upon the increase of partial oxygen pressure, which is negatively correlated with altitude. As a result, postnatal transition may be different at high altitudes. Umbilical cord blood gas analysis is now recommended in all high-risk deliveries because of its' value in providing information about preceding fetal hypoxic stress. But there are only limited studies about the SpO2 measurements during the first few hours after birth and umbilical blood gas analysis at high altitudes, especially at altitudes above 2500m. The primary outcome of the study is to determine the reference intervals for preductal oxygen saturation during first 2 hours of life stratified by different gestational age. The secondary outcomes is to establish the pH and lactate cutoff value of umbilical arterial blood gas at different altitude level.
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in reproductive-aged women， which associated with increased risks to develop metabolic disorders, including cardiovascular diseases, diabetes mellitus, and cerebrovascular diseases. The precise pathogenesis of PCOS remains unknown but is thought to be multifactorial, comprising genetic and environmental factors .
The main aim of the study is to investigate whether the transcutaneous vagus nerve stimulation(tVNS) improves the ability of inhibitory control in an emotional Go-Nogo task.
