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 recovery is an important part of the patient's experience. A good recovery period is an important guarantee for the recovery of postoperative organs and functions after surgery. However, the delay in awakening after general anesthesia remains one of the biggest challenges facing anesthesiologists. The time of resuscitation depends on patient factors, effects of anesthetic factors, duration of surgery, and painful stimulation. The delay of recovery after anesthesia was mainly caused by the use of anesthetic drugs during the perioperative period. The drugs commonly used during the perioperative period are opioid analgesics, sedatives and muscle relaxants. Studies have shown that intravenous opioids are more difficult to control than neuromuscular relaxants. Opioids can extend the recovery time after anesthesia by direct sedation of opioid receptors. It also reduces the sensitivity of brainstem chemoreceptors to carbon dioxide, leading to dose-dependent respiratory depression and hypercapnia, which affects the removal of volatile substances and carbon dioxide, and ultimately leads to coma. In addition, the active metabolites of some opioids can prolong the duration of action, especially in the case of impaired renal function, which can lead to delayed awakening. As an opioid antagonist, nalmefene can inhibit or reverse the respiratory inhibition, sedation and hypotension effects of opioid drugs. Moreover, it has no opioid excitatory activity, does not produce respiratory inhibition, hallucinogenic effect or pupil dilation. In terms of inducing wakefulness during anesthesia, nalmefene can effectively reverse the sedative effect caused by opioids. There have been reports at home and abroad that nalmefene can be used to improve the effect of post-anesthesia resuscitation and reduce agitation during the waking period, but there is still a lack of large sample and well-designed randomized controlled studies to provide important data on how to improve the quality of anesthetized resuscitation. This study will conduct a rigorous randomized controlled studies,with large sample, and the research indicators for patients from the PACU roll-out to ordinary ward, using Aldrete score , in order to obtain a series of data of nalmefene used for anesthesia recovery , and to set the foundation of related research of nalmefene and similar drugs in clinical application in the future.
Epidemiologic studies have revealed a tremendous increase in the prevalence of pituitary disease and related mortality worldwide. In order to meet all the challenges in the treatment of pituitary disease in China, CAPASITY was founded in 2020. The objective of CAPASITY is to launch a pituitary disease management model based on the Internet health information platform. It allows the application and evaluation of pituitary disease treatment strategies at multiple centers. The proprietary electronic medical database will help the dynamic big-data analysis in epidemiology of pituitary disease, diagnosis, and treatment.
Patients were aged >18 years with histological confirmed GC/EGJC and were refractory to the first line of therapy. Additional eligibility requirements included: ≥1 measurable disease at baseline per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v 1.1); Eastern Cooperative Oncology Group Performance status of 0 or 1; or life expectancy of ≥ 3 months and adequate organ function. The main exclusion criteria were interstitial lung disease, pulmonary fibrosis, active or prior autoimmune disease or active hepatitis, or history of anlotinib or any other PD-L1/PD-1 antagonist treatment. Patients with abdominal fistula, diverticulitis, gastrointestinal ulcerative disease or perforation, or abdominal abscess within the prior 4 weeks were also excluded. This study was an open, exploratory single-arm, phase II trial. Enrolled patients received anlotinib (12mg, po. qd, d1-14) combined with toripalimab (240 mg, inv, over 30 min once every 2 weeks).
This study will evaluate the efficacy and safety of mosunetuzumab in combination with lenalidomide (M + Len) compared to rituximab in combination with lenalidomide (R + Len) in participants with relapsed or refractory (R/R) follicular lymphoma (FL) who have received at least one line of prior systemic therapy.
Acute intestinal GVHD is the main cause of death after allo-HSCT, and FMT is a new treatment method for this disease. In this prospective study, the investigators will recruit intestinal GVHD patients to demonstrate the efficacy and safety of FMT.
The study aims to explore the genetic pathogenesis of diminished ovarian reserve via whole-genome sequencing technology in Chinese women.
This study aims to explore the role of PD-1 Antibody in preventing adenomatous polyps and second primary tumors in patients with Lynch Syndrome. There two arms, one is the experimental arm (PD-1 antibody prevention group) and the other is the control arm (routine follow-up group). For the experimental group, Tripleitriumab (PD-1 antibody) is given every 3 months for a year.
Before cataract surgery, subjects in the observation group used iTrace ocular aberration analyzer（itracey Technologies）and IOL-Master 700 biometer to measure the preoperative DLI(Dysfunctional lens index) and SS-OCT image of the lens, and The researchers used the anterior segment slit lamp to take photos of the anterior segment of the subject's lens in a state of dilated pupils .and self-scoring of the preoperative visual quality assessment scale. Healthy subjects in the control group also need to complete the above inspections. After that, three experienced cataract specialist surgeons combined the preoperative optometry data of each subject, the photos of the LOCS III anterior segment and the Catquest-9SF questionnaire score to determine whether each subjects should undergo cataract surgery. The subjects were divided into cataract surgery group and non-surgical group. Finally, statistically study the correlation between the DLI index and the degree of lens opacity that has been collected, and use the ROC curve to calculate the DLI as the best cut-off point of DLI to distinguish whether to perform cataract surgery.
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) significantly increases the mortality of the patients with COPD. Guidelines have recommended systemic glucocorticoid as regular treatment. Recently, evidences have shown that systemic glucocorticoid cannot not be benefit to all of the patients with AECOPD. Thus the problem that how the clinicians can screen the patients who can benefit from systemic glucocorticoid needs to be solved urgently.
To assess the impact of comprehensive staging surgery with no lymphadenectomy on survival and quality of life in patients with early-stage ovarian cancer.
