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.
This study aims to explore and investigate the therapeutic effect and mechanism of individualized localization of transcranial magnetic stimulation on emotional blunting of depression, improve the understanding of the mechanism of emotional blunting of depression, order to provide new treatment methods and better curative effects for this disease.
In this double-blinded, randomized, sham-controlled trial, the investigators aim to determine the acute effectiveness of duration-doubled tDCS on suicidal ideation in patients with MDD. In addition to the their usual treatment, participants will be randomly assigned to receive either 10 weekday sessions of active (2 mA) or sham tDCS as an adjunctive treatment, with the anode over the left DLPFC and the cathode over the right DLPFC. The investigators will regularly assess suicidal ideation, depression severity and functional impact using the BSI, HAMD-17, MADRS, ODQ, YMRS, ASRM, CGI and SDS throughout the trial. The investigators will assess cognitive changes using WCST and SCWT. The investigators will also regularly assess treatment-related side effects using validated scales.
This is a prospective, multi-center, randomized study evaluating the efficacy and safety of fruquintinib combined with chemotherapy vs bevacizumab combined with chemotherapy as second-line treatment in patients with metastatic colorectal cancer. Patients will receive fruquintinib+ FOLFIRI or bevacizumab+FOLFIRI as the second-line treatment. After receiving 4-6 months of second-line treatment, patients who achieve disease control will receive fruquintinib + capecitabine or bevacizumab+ capecitabine as maintenance treatment. All patients will be treated until progressive disease, death from any cause, unacceptable toxicity or informed consent withdrawal.
The study evaluates the combination of immunotherapy of PD-1 antibody and neoadjuvant short-course radiotherapy in early low rectal cancer. A total of 34 patients will receive 5*5Gy short-course radiotherapy, followed by 4 cycles of capecitabine plus oxaliplatin (CAPOX) chemotherapy and PD-1 antibody, finally receive the local excision(TEM) or total mesorectal excision (TME). The rate of complete response (CR, pCR + sustained cCR for ≥ 1 year), Organ retention rate, long-term prognosis, and adverse effects will be analyzed.
The prevalence of cognitive impairment in maintenance hemodialysis (MHD) patients is 3 to 5 times higher than that in ordinary people, so it is essential to find the associated risk factors in this population. This project intends to evaluate whether changes in cerebral blood flow during dialysis have an impact on cognitive function in middle-aged and elderly MHD patients and clarify their influence on brain imaging characteristics. MHD patients who started hemodialysis at 3 to 6 months were selected to examine the difference in middle cerebral artery flow rate before and after dialysis by transcranial Doppler ultrasound to reflect the changes in cerebral blood flow. Changes in the cognitive function scale assessment (memory, executive function, and other five cognitive domains) and brain magnetic resonance imaging examinations are planned to collect both at baseline and after a one-year follow-up. Then the investigator used the multiple linear regression method to analyze the effects of the difference in middle cerebral artery flow on the changes in cognitive function and the characteristics in brain imaging. The investigators anticipate that the characteristics of the influence of changes in cerebral blood flow on cognitive impairment in Chinese MHD patients will be elucidated in this study, which may provide crucial clinical evidence for finding preventive and intervention measures for cognitive impairment in this group of population.
This study is designed to assess the efficacy and safety of datopotamab deruxtecan (Dato-DXd) in combination with pembrolizumab versus pembrolizumab in combination with pemetrexed and platinum chemotherapy in participants with no prior therapy for advanced or metastatic non-squamous non-small cell lung cancer (NSCLC).
This Phase II/III study assessed the efficacy, safety, pharmacokinetics, and immunogenicity of B013 administered with nab-paclitaxel in participants with locally advanced or metastatic triple negative breast cancer (TNBC) who have not received prior systemic therapy for metastatic breast cancer (mBC).
Postoperative cognitive dysfunction (POCD) refers to the difficulties of orientation, cognition, communication, memory and abstract thinking of patients after anesthesia and surgery. And/or accompanied by the decline of the ability in social activities, such as the change of personality, social ability of language and behavior, cognitive function and life skills. POCD is a common complication of central nervous system in elderly patients after operation, with an early incidence of about 21% and a long-term incidence of about 35% . According to the current research on Alzheimer's disease (AD) and POCD in the elderly, it has been found that they have similar pathological basis and some homologous related genes. Altogether, POCD is closely related to molecular pathway neuropsychiatric diseases (such as dementia, depression and Alzheimer's disease). Researchers have come up with various hypotheses to reveal the underlying mechanisms of POCD, including neuritis, oxidative stress, autophagy disorder, synaptic dysfunction, and lack of neurotrophic support. To date, apart from evaluating with scales, CT Scan and EEG analysis, there is neither exact biomarkers for monitoring and diagnosing POCD, nor clear relationships between specific Brain Metabolomic Characteristics, EEG changes and diagnosis of POCD, so that the diagnosis of early POCD only stays in the evaluation of clinical symptoms and scales. Therefore, our study aims to provide an effective basis for early diagnosis and treatment of clinical POCD through multivariate analyses of clinical scales combined with Brain Metabolomic Characteristics, EEG analysis of patients.
