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.
In recent years, many scholars have studied the ocular surface damage of patients with dry eye disease（DED）after FS-LASIK, but there has been a lack of comprehensive observation and research on the relationship and difference between dry eye （DE）patients with and without LASIK. Therefore, the purpose of this study was to investigate the characteristics of ocular surface and cytokines after FS-LASIK, and further explain the pathogenesis of chronic dry eyes after FS-LASIK. In addition, we will also compare clinical characteristics and tear neuropeptide concentrations in patients with dry eye disease (DED) with and without chronic ocular pain following FS-LASIK, and to investigate correlations between ocular pain, clinical characteristics, and tear neuropeptide levels.
Lymphoma-associated hemophagocytic lympohistiocytosis is a refractory immune disorder with high mortality. Early identification and diagnosis of lymphoma-associated HLH has become the key to improve the prognosis of lymphoma-associated HLH. Therefore, we conduct a multicenter, prospective, observational clinical study to explore the sensitivity and specificity of cytokines for the early diagnosis of lymphoma-associated HLH.
To evaluate the efficacy and safety of ruxolitinib for prophylactic therapy of adult patients who are predicted to have a high risk for developing severe acute graftversus-host disease (aGVHD) by the dynamic aGVHD Onset Anticipation Tianjin (daGOAT) model.
This study hopes to: 1. explore whether, at the individual level, the improvement of mindfulness ability can promote peace of mind, reduce the frequency of mental wandering, weaken or cut off the cycle between negative mood and mind wandering, and improve the individual's attention monitoring ability and ability to engage in the present. 2. explore the impact of mindfulness intervention on intimate relationships in the eastern culture under the intimate relationship interaction model. 3. explore and propose the level of personality functioning could be a moderator of outcomes of MIED.
Patients with successful left bundle branch pacing in our center were included in this study from April 2018 to December 2019. Baseline data was collected, and pacing parameters, ECG and echocardiographic results were analyzed during 3 years follow-up. According to whether or not a potential was recorded and the specific potential characteristics at implantation, the patients were divided into 3 groups: left bundle branch potential group; Purkinje potential group; and no-potential group. During the 3 years follow-up, the investigators collected the ECG、UCG and pacemaker parameters to analyze.
It is a single arm, multicenter, phase 2 study to explore the efficacy and safety study of OR-MTX chemotherapy（Orelabrutinib, Rituximab and Methotrexate）as first-line regimens in the treatment of newly diagnosed primary central nervous system lymphoma. Objective response rate is the primary endpoint.
The purpose of this study was to explore the accuracy of sentinel skin grafts from the same donor source in diagnosing renal allograft rejection, and to provide new ideas and options for the later clinical diagnosis of renal allograft rejection. Further, try to provide timing guidance for early immunization intervention.
This study aims to evaluate and screen out the factors related to the improvement of eustachian tube function after adenoidectomy and/or tonsillectomy, so as to guide the treatment of children's eustachian tube function before and after operation, and provide the treatment direction and methods for diseases related to eustachian tube dysfunction for people with adenoid hypertrophy and/or tonsil hypertrophy complicated with ETD.
Anxiety and depression in later life are highly prevalent, often appear as comorbid disorders, and have many adverse consequences for both the individual and society. Given the disease burden, the large influx of new cases, and the economic costs, efforts should be made to prevent the onset of anxiety and depression in later life. Preventive interventions are likely to become more cost effective when they are targeted at elderly who have been exposed to risk factors known to be predictive of the onset of anxiety and/or depression. As the population aging is speeding up, senile diseases have become a significant and severe public health problem, influencing national health. More than 20 million elderly patients undergo surgery each year in China, accounting for a quarter of the population who undergo surgery. Therefore, it is necessary to construct a predictive model of anxiety and depression in perioperative elderly hospitalized patients
This study was to explore the effectiveness and safety of early TMZ chemotherapy between surgery and chemoradiotherapy plus the standard concomitant radiochemotherapy regimen.
