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.
Water method with water exchange has been shown to reduce medication requirement and pain experienced during colonoscopy. It increases the success rate of cecal intubation in sedated and unsedated patients undergoing screening colonoscopy. Exchange of water during scope insertion minimizes distension of the colonic lumen and decreases loop formation. Exclusion of air from the colon during insertion by omission of air insufflations and suction removal of residual air prevent elongation of the colon. These maneuvers facilitate colonoscopy insertion in average patients and may enhance the success of difficult colonoscopy. Older age is independently associated with incomplete colonoscopy, the investigators postulate that these patients may benefit from using the water method for colonoscopy. In this proposal the investigators test the hypothesis that compared with conventional air insufflations the water method with water exchange significantly enhances the success rate of cecal intubation in elder patients. The aim of the study is to compare the outcome of colonoscopy using the water method versus the conventional air method in elder patients. The primary outcome is cecal intubation success rate. The secondary outcomes include cecal intubation time, maximum pain score during colonoscopy, overall pain score after colonoscopy and adenoma detection rate.
Non - small cell lung cancer ( NSCLC ) accounts for more than 80% of lung cancer. The main treatment for early stage patients is surgical resection, but about 30% -70% patients will relapse. Postoperative chemotherapy is the major systemic treatment for surgical resection NSCLC patients. However, data show only 5-10% improvement in overall survival with systemic adjuvant chemotherapy. It is necessary to further improve the survival time of patients with lung cancer. Biological treatment is becoming a new treatment modality for Cancer following with surgery, radiotherapy and chemotherapy, and has been confirmed as an effective adjuvant treatment in comprehensive cancer treatment. Cytokine induced killer cells ( CIK) characterized as fast amplification, strong anti-cancer activity and broad anti-tumor spectrum is most widely used and thought to be the first choice for the new generation of anti-tumor adoptive immunotherapy. This Phase II study is investigating the efficacy of Autologous Cytokine-Induced Killer Cell Transfusion plus Chemotherapy as adjuvant therapy for stage IB-IIIA NSCLC.
Animal studies showed that many general anesthetics might result in neuron apoptosis and neurocognitive impairment in the developing brain. However results from human studies are conflicted. In present study, the investigators examined the association between early exposure to anesthesia and surgery for minor surgery and intelligence changes in adolescence using the Wechsler Intelligence Scale for Children.
The purpose of this study is to determine if 48 weeks of therapy with Pegylated Interferon Lambda plus Ribavirin is effective and safe for a treatment of chronic hepatitis C (CHC) compared to therapy with Pegylated Interferon Alfa-2a plus Ribavirin.
Some previous studies has demonstrated that Metformin can improve the weight gain which caused by antipsychotics. An our study, which will be published, also found that Metformin can improve the amenorrhea for patients with antipsychotics, approximately 60% patients recovery period. So the present study was designed to investigate the efficacy and safety of Metformin in preventing patients with Risperidone from weight gain and amenorrhea.
All experimental group patients of 100 patients accept a treatment course stem cell transplantation, including one time stem cell transplantation through intravenous injection way at the 10-21th day of cerebral hemorrhage, and the 7—14th day of cerebral infarction incidence; the second time transplantation through lumbar puncture way at the 7th day after the First time transplantation. The control group gives injection through intravenous and lumbar puncture ways separately in the corresponding time, but the transplantation matter is physiological saline not the stem cell.
The purpose of this study is to determine whether dexmedetomidine is effective in the treatment of emergence delirium of preschool children undergoing oral maxillofacial surgery.
Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Cypher SES (Cordis, MA) has been proved by several randomized clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai), comparing with Cypher SES.
The purpose of this study is to determine whether Recombinant Human Interleukin-11 (rhIL-11) Combination Low-dose Rituximab prednisone are effective and safe in the management of Steroid-Resistant/Relapsed Immune Thrombocytopenia (ITP).
The CSSPT study is a multi-center, randomized, double blinded, placebo-controlled secondary stroke prevention trial in China to determine whether the addition of folic acid and vitamin supplements will reduce recurrent stroke events and other combined incidence of recurrent vascular events and vascular death.
