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.
Postoperative sore throat (POST) is an important problem after general anaesthesia. We assessed whether chewing gum preoperatively can reduce the incidence of POST after general anaesthesia administered via a streamlined liner of the pharyngeal airway (SLIPA).
Chronic Obstructive Pulmonary Disease (COPD) is currently the fourth leading cause of death in the world. Acute exacerbations of COPD (AECOPD) are the most important events in the course of the disease because they negatively impact health status, life quality, disease progression, patients survival and economic and social burden. Reducing frequency of AECOPD is the key goal of management for COPD. Since respiratory viral infections are the mainly trigger of AECOPD, anti-viral therapy would be the affective method to prevent the exacerbation or reduce the attack severity. However, there are no positive study results of treating or preventing AECOPD used by current anti-viral drugs approved by FDA so far. Arbidol is a non-nucleoside antiviral drug. It inhibits viral DNA and RNA synthesis by inhibiting fusion of viral lipid vesicle membrane with host cell membranes. Arbidol has broad-spectrum antiviral activity. In addition to inhibition of influenza virus, it against a variety of viruses including respiratory syncytial disease (RSV), parainfluenza virus, human rhinovirus, coxsackie virus (CV), adenovirus (ADV) and so on. In recent years, some fundamental and clinical researches have shown that arbidol has a significant role in prevention and treatment of influenza virus and other acute respiratory viral infections. Therefore, the investigators speculate that Arbidol will effectively control COPD combined with upper respiratory virus infection, thereby reducing acute exacerbations of COPD. This is a prospective, multicenter, randomized, double-blind, placebo-controlled, 52-week study. The purpose of this study is to evaluate the efficacy and safety of arbidol in improving the frequency and extent of moderate or severe acute exacerbations in patients with COPD. Eligible subjects will be randomly assigned to treatment group or placebo group at a 2:1 ratio. Subjects of treatment group receive an on-demand arbidol 200 mg three times per day while placebo group receives matched placebo. When the subject has a new respiratory infection, original respiratory symptoms worsen, or fever (the lower body temperature is greater than 37.3℃), oral medication is given immediately. The subjects are required to receive the first dose of drug within 8 hours after the symptoms of upper respiratory tract infection.
This study aims to evaluate the feasibility, effectiveness, and safety of in-situ laser-assisted fenestration on the left subclavian artery during the procedure of thoracic artery endovascular repair
In this prospective clinical study, the researchers investigate the incidence of catheter-related thrombosis and catheter-related infection during indwelling central venous catheterization in critically ill patients, and analyzed the risk factors for catheter-related complications and the relationship between catheter-related thrombi and catheter-related infections. The sample size is about 500.
There are limited data from retrospective studies regarding whether short-term and long-term outcomes after laparoscopic or robot-assisted radical colectomy (minimally invasive surgery) are equivalent to those after open abdominal radical colectomy (open surgery) among patients with early and medium-stage colorectal cancer. This trial is a multicenter,prospective, randomized trial evaluating short-term and survival outcomes concerning minimally invasive surgery and open surgery for colorectal cancer.

To explore the effects of combined traditional Chinese and Western medicine( Chinese acupuncture combined with Amisulpride Tablets) on negative symptoms, cognitive function and social function in patients with schizophrenia, and the side effects and safety of Chinese acupuncture combined with Amisulpride Tablets.
The purpose of this study is to evaluate the efficacy and safety of concurrent radiotherapy with Apatinib in patients with Brain Metastases from drive gene wide-type Non-small-cell Lung Cancer (NSCLC).
Metabolic surgery, as a recognition treatment option for patients with clinical morbid obesity, is gaining increasing appreciation. In addition to substantial weight loss, emerging studies have highlighted that metabolic surgery can substantially ameliorate obesity-related metabolic diseases, including but not limited to type 2 diabetes mellitus (T2DM), hypertension, dyslipidemia, obstructive sleep apnea-hypopnea syndrome (OSAHS) and polycystic ovary syndrome (PCOS)in severely obese patients. However, further investigations with larger sample size and longer observation time still needed to clarity the efficacy and safety of metabolic surgery in Chinese patients with obesity and encouraging future research in this field.
