There are about 28453 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.
Despite major advances in the field of psychopharmacology in recent years, the majority of treated schizophrenia patients retain disabling symptoms, most commonly a variety of negative symptoms. Currently, clinical treatment of schizophrenia remains dominated by pharmacological control. The current use of antipsychotic medications is effective in controlling the positive symptoms of schizophrenia, but has little effect on the negative symptoms. Neuroimaging and neurophysiological studies have shown that negative symptoms are associated with abnormal brain activity in the combined right and left dorsolateral prefrontal and temporoparietal joint regions, and that physical therapy techniques can modulate cortical activity. Therefore, this study aims to investigate the efficacy of transcranial direct current stimulation(tDCS) combined with repetitive transcranial magnetic stimulation(rTMS) on negative symptoms in patients with schizophrenia and to explore possible mechanisms. The double-blind randomized placebo-controlled study comparing active tDCS stimulation combined with active rTMS stimulation, active rTMS stimulation combined with sham tDCS stimulation, and active tDCS stimulation combined with sham rTMS stimulation to sham tDCS stimulation combined with sham rTMS stimulation at 4 weeks of treatment and 2 weeks of follow-up in patients with predominantly negative symptoms with schizophrenia was studied for efficacy. In addition to the primary observation of changes in the Negative Symptom Assessment Scale (SANS), secondary outcomes include changes in Positive and Negative symptom scale (PANSS) total and negative total scores, changes in the MATRICS Consensus Cognitive Battery (MCCB), changes in local brain activity (functional magnetic resonance imaging, fMRI), white matter integrity (diffusion tensor imaging, DTI), changes in laboratory examination indices changes and changes in psycho-behavioral and EEG index. This is the first clinical trial combining tDCS with rTMS for the treatment of schizophrenia patients with predominantly negative symptoms. This study will provide solid evidence for the combination of tDCS with rTMS for the treatment of negative symptoms in schizophrenia. This study will also help to further explore the mechanisms of tDCS combined with rTMS for the treatment of negative symptoms in schizophrenia in terms of imaging and behavior.
The main aim is to determine whether vitamin C can reduce 28-day all-cause mortality or persistent organ dysfunction compared with placebo in patients with severe and critical ill COVID-19 patients. Participants will randomly receive HIVC or placebo for 4 days once enrolled. The primary outcome is a composite of death or persistent organ dysfunction (defined as dependency on vasopressors, mechanical ventilation, or CRRT) at day 28 after randomization.

To reveal the effects of circadian rhythm disorder on human intestinal microorganisms and metabolism on other potential diseases. In this study, 40 people with circadian disorders and 40 healthy controls were recruited. During the study, blood, urine and fecal samples of the subjects were obtained once, and the obtained biological samples were tested and analyzed by serum, urine metabolomics and fecal metagenomics. Subjects were also evaluated on the following scales : Circadian Type Inventory（CTI ）. The Epworth Sleeping Scale ( ESS ), Fatigue Scale-14 ( FS-14 ), Maslach Burnout Inventory-General Survey ( MBI-GS ), Athens Insomnia Scale ( AIS ), Insomnia Severity Index ( ISI ), Pittsburgh sleep quality index ( PSQI ), Bristol Stool Scale, Gastrointestinal Symptom Rating Scale ( GSRS ), Connor-Davidson resi.
With the steady development of catheter ablation, it has gradually become the main treatment of various arrhythmias. Antithrombotic and anticoagulant therapy after catheter ablation determines the occurrence of perioperative bleeding and ischemic events. However, the incidence, characteristics and short-term prognosis of secondary acute cerebrovascular events in patients with arrhythmia after catheter ablation have not been studied. Methods: This study was intended to retrospectively collect and analyze the case data and auxiliary examination results of patients with arrhythmia who underwent catheter ablation. To evaluate the incidence, clinical features and short-term prognosis of secondary acute ischemic and hemorrhagic cerebrovascular events in patients with arrhythmia after catheter ablation. In order to improve the quality of life of patients, reduce the secondary acute cerebrovascular complications in the hospital in patients with arrhythmia after catheter ablation, to provide evidence for promoting the clinical management of such patients, and to provide help for the maximum degree of prevention and control risk.
Sarcopenia is a geriatric condition characterized by a progressive decrease in skeletal muscle content and loss of muscle function. Resistance exercise, Taichi exercise and the hybrid exercise program consisting of the two aforementioned methods have been demonstrated could increase the skeletal muscle mass of the elderly with sarcopenia. However, note that the above contents may be performed in a different order in a treatment, equally important but less well understood is the sequence in which it should be performed. Surprisingly, the exercise sequence has not been comprehensively investigated. Therefore, investigators designed a self-ordered exercise program combining resistance exercise, tai chi and a hybrid exercise program to investigate whether the decline in skeletal muscle area could be better overcome and the reversal of sarcopenia in elderly with sarcopenia.
Malnutrition caused by reduced food intake or assimilation and varying degrees of acute or chronic inflammation is a serious and underappreciated risk factor for adverse clinical outcomes. Despite the substantial health and economic burden, malnutrition remains to affect a considerable proportion of hospitalized patients worldwide. Nationally representative studies from the USA, Australia, and European countries have reported prevalence figures in the range of 8.9% to 80.4%. However, national data in some resource-poor countries, such as China, the largest developing country in the world, are scarce. We did the China Nutrition Fundamental Data 2020 in a large, nationally representative sample of Chinese adult inpatients to 1) Explore the relationship between nutrition and health; 2) Understand the capacity of nutrition services in Chinese medical institutions. This project adopted a multistage, stratified, cluster-sampling procedure based on administrative divisions in China. For each participant, a structured interview was done by trained nutritionists or clinicians. The following data were acquired: weight change within and beyond six months, food intake change within two weeks, nutrition therapy during this hospitalization, and laboratory tests. We also collected information on participants' sociodemographic characteristics and medical history. We took physical measurements, including height, weight, waist circumference, hip circumference, mid-arm circumference, calf circumference, handgrip strength, and blood pressure following standard protocols. Body composition was measured using bioimpedance analysis (BIA). In total, 54677 inpatients from 291 project hospitals completed information collection. In addition, we collected information on the number of beds, the nutrition support team, the nutrition treatment plan and the construction of a full-time nutrition physician or nutrition nurse, the routine monitoring methods, interventions, and distribution of brochures for patients with malnutrition or nutritional risk in each project hospital and 37 other hospitals based on the principle of voluntary participation. A total of 328 hospitals completed information collection. This project will establish standards for nutrition risk assessment, diagnosis, and treatment of inpatients in China, promote the construction of clinical nutrition departments, and improve the nutritional status of inpatients.
In view of the increasingly severe aging situation in China, the perioperative brain health of elderly patients has received increasing attention. Postoperative delirium (POD) is a common postoperative complication characterized by acute consciousness and cognitive dysfunction. The incidence of POD in elderly patients undergoing elective non cardiac surgery is 20%~45%, which often indicates poor cognitive recovery and becomes a heavy burden for family and society. Although the weight of human brain only accounts for 2% of body weight, the oxygen consumption accounts for 20% of the total oxygen consumption of the whole body. On July 2, 2022, the British Journal of Anaesthesia (Chinese Academy of Sciences Division 1, Anesthesiology Division 1, IF11.719), the top international Journal in the field of anesthesiology, published the scientific research achievements of the first author of the applicant. It was found for the first time that sevoflurane, the most commonly used inhalation anesthetic in clinical practice, can cause the activation of glycolysis and the increase of lactic acid in the brain of elderly non-human primate marmosets, which suggests that general anesthetics will affect brain metabolism in the perioperative period. Therefore, we hypothesized that perioperative changes in brain metabolism might be related to the occurrence of POD in elderly patients. The purpose of this study was to study the relationship between the changes of brain metabolites and POD during perioperative period by noninvasive monitoring of the characteristics of brain tissue metabolites 24 hours before and 24 hours after the operation with hydrogen ion proton magnetic resonance spectroscopy (1-HMRS). In order to complete this purpose, this study plans to collect subjects aged 65~90 years who are scheduled to undergo oral and maxillofacial surgery under general anesthesia. The changes of brain metabolites before and after operation were collected by 1-HMRS, and the postoperative delirium related scale was evaluated to analyze the relationship between perioperative changes of brain metabolites and POD.
