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 is a multicenter, open-label study conducted in 3 phases: Dose escalation stage: The stage contain 4 cohorts, each cohort divided into 2 groups （group A, single dose and Group B, multiple dose）.Dose escalation will use a 3+3 design to evaluate escalating doses of T3011.Cohorts of three subjects will be enrolled at each T3011 dose level with expansion to six subjects, if necessary, to assess toxicity. Total enrollment will depend on the toxicities observed, with approximately 4-24 evaluable subjects enrolled in dose escalation stage. Dose extension stage: The SMC will evaluate the available safety and preliminary efficacy data and initiate dose-expansion studies for the appropriate indications Phase IIa: To explore the safety of intravenous administration and expand the study in other indications. the stage will be carried out gradually based on the data obtained from the phase I study.
About 200000 cardiac operations are performed in China every year. Cardiopulmonary bypass is the basic strategy of open-heart surgery, which may lead to myocardial ischemia-reperfusion injury and low cardiac output syndrome. It will inevitably affect the patient's postoperative recovery. A number of studies have shown that dexmedetomidine, as an auxiliary sedative, has the effects of inhibiting stress response, antiarrhythmia and cardiac protection.Dexmedetomidine has been widely used in anesthesia in cardiac surgery. However, at present, few clinical studies pay attention to its mechanism. In this study, dexmedetomidine will be used in cardiac surgery with cardiopulmonary bypass to explore the mechanism of cardiac ischemia-reperfusion injury and the protective effect of dexmedetomidine.
Background. Consensus is lacking regarding the use of tranexamic acid (TXA) in calcaneal fracture surgery. This study aims to investigate the hypothesis that local infiltration of TXA in the post-operation would maintain hemoglobin (Hb) level, reduce incision drainage volume and risk of infection in patients with displaced intra-articular calcaneal fractures. Methods. A total of 120 patients with displaced intra-articular calcaneal fractures who received extensible lateral L-shaped approach were included in this trial and equally randomized to receive one single dose of 1g TXA or 1g normal saline after closing incision. The demographic data and fracture characteristics, intra-operative indicators, laboratory tests and Visual Analogue Scale (VAS) scores, incision drainage volume, and incision-related complications were collected and compared between the two groups.
Hepatocellular carcinoma (HCC) is the sixth prevalent malignancy worldwide. Although surgical excision is considered the standard treatment for resectable HCC, a high rate of postoperative recurrence was observed after partial hepatectomy, with a marginal recurrence rate up to 30%. Narrow margin resection may be the most appropriate procedure for centrally located HCC because the premise for survival is the conservation of more normal liver parenchyma. Unfortunately, narrow margin resection has been reported to contribute to poor survival outcomes. However, no (neo)adjuvant therapy before (or after) hepatectomy is generally considered to be effective in reducing post-operative recurrence. Radiotherapy (RT) has been well used in many solid malignant tumors as an (neo)adjuvant to surgical treatment, including HCC. SBRT has shown encouraging rates of local control for HCC. Compared with standard fractionation radiation, SBRT can achieve more precise delivery of high-dose radiation beams to the lesion, obtaining a much smaller target volume. Meanwhile, it could be finished in a short period which can bring more convenience to patients. Recently, several study and randomized controlled trials revealed the survival benefit of adjuvant RT (IMRT and SBRT) in patients with HCC. However, there are still lack of exploration for the efficacy of neoadjuvant SBRT. This study is to analyze the safety of preoperative SBRT followed by hepatectomy for centrally located hepatocellular carcinoma.
In 2019, the number of patients with diabetes was about 463 million in the world, accounting for 8.3% of the total population, and it is expected to rise to 578 million (9.2%) by 2030 and 700 million (9.6%) by 2045. According to the WHO diagnostic criteria, the prevalence of diabetes among adults in China from 2015 to 2017 was 11.2%, of which over 90% were type 2 diabetes mellitus (T2DM). The global prevalence of non-alcoholic fatty liver disease (NAFLD) is also very high, which was approximately 25% in 2016. The prevalence of NAFLD may continue to rise. NAFLD is often accompanied by clinical manifestations of metabolic syndrome, such as obesity, T2DM, hyperlipidemia and hypertension.
To compare the correlation between the clinical efficacy of MECT treatment and baseline, 3 times, 8 times of treatment, 1 week after treatment, and 2 weeks after treatment in patients with depression and suicidal ideation. The prediction effect of -1β and IL-6 levels and level changes on the efficacy of MECT in the treatment of suicidal ideation in elderly patients with depression, and provide a theoretical basis for further research on the mechanism of MECT in the treatment of elderly depression with suicidal ideation.
This is a single arm, multi center, exploratory clinical study to evaluate the efficacy and safety of fluzoparide combined with alpatinib as neoadjuvant therapy in patients with BRCA1/2 gene mutation or HRD gene mutation, advanced ovarian cancer, primary peritoneal cancer, fallopian tube cancer ((FIGO stage III or IV), who can not achieve R0 tumor reduction surgery after imaging evaluation or laparoscopic evaluation .
The aim of the current study is to assess if EUS-PPGM could predict the treatment response and outcomes of varices to endoscopic variceal ligation (EVL) in patients with chronic hepatitis. The hypothesis is that a high EUS-PPGM value at 3 months correlates with the presence of varices requiring EVL in patients that have received primary or secondary variceal prophylaxis on 1 year follow-up upper endoscopy.
The goal of this cohort study is to estimate the incidence of AD in the first-degree relatives of patients with AD. The main questions it aims to answer are: - cognitive changes of subjects at high risk of AD as ageing; - environmental and behavioral factors affecting AD incidence.
The purpose of this clinical trial is to evaluate the effect of repeated low-level red-light (RLRL) therapy on the retinal function and structure among myopic teenagers.
