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.
Depressive episode of bipolar disorder is often the first symptom of patients with bipolar disorder, which is characterized by frequent recurrence, relatively long duration, high comorbidity rate and high fatality rate. People with bipolar disorder spend a third of their lives depressed, and it is these depressive symptoms that lead to long-term disability and early death. The treatment of bipolar depression is controversial. The latest Mood Disorders CPG guidelines recommend first-line therapy: quetiapine, lurasidone, lithium, valproate, lamotrigine monotherapy or combination of quetiapine, lurasidone plus Mood stabilizer, olanzapine plus fluoxetine therapy. In addition, the use of antidepressants is still controversial, and their efficacy, prognosis and risk of mania remain to be evaluated. Vortioxetine is a novel antidepressant with unique characteristics, and its multi-mode mechanism of action can be used to treat a wide spectrum of symptoms of depression. Current clinical experience suggests that the clinical conversion rate of vortioxetine is low, and the depressive symptoms and cognitive symptoms of people with depressive episodes are significantly improved. As of September 2019, a total of 4.87 million patient years (nearly 3 months of treatment with 20 million patients) were treated with vortioxetine in PSUR (Periodic Safety Update), with 51 reported cases of hypomania and 322 reported cases of mania. Based on the above data, the post-marketing conversion rate of vortioxetine is approximately 1 in 10,000 patient-years or 1 in 40,000 patients. Therefore, the efficacy and risk of transferring to mania of vortioxetine in bipolar II depressive episode deserve further investigation.
To evaluate the safety and effectiveness of ENDOANGEL Lower Gastrointestinal Endoscope Image Auxiliary Diagnostic Software developed and manufactured by Wuhan ENDOANGEL Medical Technology Co., Ltd.
It is designed for Multi-center, double-masked, randomized, placebo- control study with dose escalation phase I trial to evaluate the safety, tolerability, PK and immunogenicity profiles of a single intravenous injection of IBI311 in healthy volunteers.
The present study will explore the underlying mechanisms of problematic Internet and smartphone use by focusing on how and when environmental factors affect the positive psychological intervention factors. Hence, the present study will provide scientific empirical evidence to design and formulate follow-up intervention strategies. Aims: I. Apply the dynamic system model of addictive behavior execution in Chinese adolescents with problematic Internet and smartphone use and use longitudinal data to track and explore the underlying mechanisms of environmental factors and personal factors on problematic Internet and smartphone use. II. Identify positive psychological intervention factors that effectively prevent and reduce problematic Internet and smartphone use according to the interview and provide empirical evidence for other intervention designs. III. Conducting a positive psychological intervention in an adolescent population to verify the protective effect of positive psychology factors on problematic Internet and smartphone use. Hypotheses: I. Environmental factors (e.g., child abuse and trauma, parenting behaviors, teachers' encouragement, peer support) will affect the problematic Internet and smartphone use through personal characteristics (e.g., meaning in life); II. The effect of environmental factors on problematic Internet and smartphone use through personal characteristics will be moderated by other positive psychological intervention factors (e.g., character strengths); III. Positive psychological intervention (e.g., meaning-based intervention, strengths-based intervention) is an effective intervention strategy to prevent and reduce problematic Internet and smartphone use.
This study explores the risk factors for sarcopenia in patients with chronic kidney disease and the effects of sarcopenia on cardiovascular disease. Treatment of sarcopenia and cardiovascular complications provides a basis for improving the quality of life and survival of patients with chronic kidney disease.
Aflibercept, a recombinant fusion antibody that binds to all subtypes of VEGF and PlGF, has been shown to induce effective regression of retinal neovascularization secondary to PDR but there had been lack of a well-structured prospective study about adjunctive use of intravitreal injection of Aflibercept (IVA) to reduce postoperative VH in PPV for PDR. In this study, we aim to assess the effect of preoperative IVA on the incidence of postoperative VH after PPV for PDR.
The aim of this study is to evaluate whether preoperative CT- guided hookwire localization would influence the incidence and intensity of acute and chronic pain after VATS.
ADAMTSL4 (A disintegrin and metalloproteinase with thrombospondin motifs like) is a member of the ADAMTSL family. ADAMTSL4 is one of the family of 7 ADAMTS-Like proteins, themselves part of the Thrombospondin type 1 repeat (TSR) superfamily of proteins. These 7 proteins are divided into two distinct clades, of which ADAMTSL4 and ADAMTS-Like 6 form part of one clade, differing from ADAMTS-Like 1, ADAMTS-Like 3 and ADAMTS-Like 7 by lacking immunoglobulin repeat regions. ADAMTSL4 is widely expressed in brain, colon, heart, kidney, liver, lung, pancreas and spleen, yet, its precise role is unclear. in addition, ADAMTSL4 protein high expression to the medial layer of the arterial wall, and medial vascular smooth muscle cells specifically.
The purpose of this study is to realize the first evaluation of the psychometric characteristics of the Chinese version of the the Penn State University Electronic Cigarette Dependence Index Scale.
