Clinical trials

This single-center, prospective, controlled trial compares betacyanin versus conventional methods for early diagnosis and healing assessment of anastomotic leakage after rectal cancer surgery.

Alzheimer's disease (AD) is a severe neurodegenerative disease with heavy social burden. Current drugs cannot reverse disease progression. Brain glymphatic system and meningeal lymphatic dysfunction lead to impaired clearance of Aβ and Tau protein, which is an important pathogenesis of AD. Deep cervical lymphovenous anastomosis (DCLVA) can improve intracranial lymphatic drainage, promote the clearance of toxic proteins, and improve neurological function. This is a single-arm, prospective, self-controlled study to enroll 59 patients with severe AD (MMSE \< 10). All patients receive bilateral DCLVA plus routine medication. The primary endpoint is change of CDR-SB score at 12 months post-operation. Secondary endpoints include MMSE, ZBI scores and Aβ PET-CT Centiloid value. This study aims to verify the efficacy and safety of DCLVA for severe AD.

The DATE-AGING study is a prospective, multicenter, randomized controlled trial investigating low-dose tenecteplase in elderly patients with acute ischemic stroke. Its primary objective is to evaluate the safety and efficacy of low-dose tenecteplase in elderly patients within 4.5 hours of acute ischemic stroke onset.

This is a multicenter, prospective, open-label, endpoint-blinded randomized controlled clinical study. We aim to evaluate the safety and efficacy of deep cervical lymphovenous anastomosis (LVA) combined with routine treatment for patients with moderate Alzheimer's disease, compared with routine treatment alone. A total of 296 eligible participants aged 50 to 80 years with moderate Alzheimer's disease will be enrolled and randomly divided into two groups at a 1:1 ratio. One group will receive deep cervical lymphovenous anastomosis plus standard routine treatment, while the other group will only receive standard routine treatment for Alzheimer's disease. All participants will be followed up for 12 months after randomization. We will assess cognitive function using MMSE and CDR-SB scales, evaluate caregiver burden via ZBI scale, and detect changes in Alzheimer's disease related biomarkers including blood amyloid-beta and tau protein, as well as Aβ-PET imaging indicators. The main goal is to observe whether this surgical procedure can improve patients' neurological function and clear abnormal protein deposits in the brain, and confirm its long-term safety. This study strictly follows ethical principles. Every participant or their legal representative will sign a written informed consent before enrollment. During the whole study period, we will closely monitor all adverse events to ensure the safety of participants.

DATE-MeVO is an investigator-initiated, multicenter, prospective, randomized controlled, open-label, blinded endpoint (PROBE) clinical trial aiming at evaluating the efficacy and safety of tenecteplase combined with standard medications in acute ischemic stroke patients with medium vessel occlusion stroke within 24 hours of onset.

To establish a prospective, multicenter, real-world cohort of patients with osteomyelitis, by systematically collecting and analyzing detailed treatment and follow-up data, in order to provide clinical evidence for the standardization of its treatment

This \[Study Type: Clinical Trial\] aims to \[Primary Objective: evaluate the long-term efficacy and safety of robotic gastrectomy for locally advanced gastric cancer\] in \[Participant Population: patients with locally advanced gastric cancer, aged \>18 years and \<75 years\]. The primary questions it seeks to answer are: Is the 3-year disease-free survival rate of robotic gastrectomy non-inferior to that of laparoscopic gastrectomy? Is the perioperative safety of robotic gastrectomy superior to that of laparoscopic gastrectomy? Researchers will compare \[Intervention Groups: Robotic Gastrectomy vs. Laparoscopic Gastrectomy\] to determine whether \[robotic surgery offers advantages in long-term efficacy and perioperative safety\]. Participants will: Sign an informed consent form and be randomly assigned to either the robotic surgery group or the laparoscopic surgery group. Undergo the assigned surgical procedure and receive regular follow-up visits (at 30 days, 3 months, 6 months, 9 months, 12 months, 15 months, 18 months, 21 months, 2 years, 2.5 years, and 3 years postoperatively). Complete physical examinations, blood tests (including complete blood count, biochemical markers, and tumor markers), and imaging studies (such as abdominal CT, upper gastrointestinal endoscopy, and chest X-ray) during the follow-up period.

This is a multicenter, randomized, controlled clinical trial comparing neuroendoscopic hematoma removal to craniotomy in the treatment of large intracerebral hemorrhage.

The clinical trial aims to assess the efficacy and safety of Tislelizumab combined with the SOX regimen and HIPEC in treating locally advanced gastric cancer. The primary and secondary objectives are as follows: To evaluate the 3-year disease-free survival (DFS) in patients with locally advanced gastric cancer treated with systemic SOX chemotherapy plus Tislelizumab and HIPEC. To assess the major pathological response (MPR) in these patients.

Participants will: Be willing to receive SOX plus Tislelizumab combined with HIPEC treatment (exposure group), undergo HIPEC followed by SOX and Tislelizumab to achieve stable disease (SD), partial response (PR), or complete response (CR). Patients who can undergo surgery after the second exploration will receive surgery and HIPEC treatment. If surgery is not possible, a multidisciplinary team (MDT) discussion will follow to determine the next treatment plan. Patients with progressive disease (PD) will also have an MDT discussion to determine the subsequent treatment. Be willing to receive SOX combined with HIPEC treatment (observation group), undergo HIPEC followed by SOX to achieve SD, PR, or CR. Patients who can undergo surgery after the second exploration will receive surgery and HIPEC treatment. If surgery is not possible, an MDT discussion will follow to determine the next treatment plan. Patients with PD will also have an MDT discussion to determine the subsequent treatment.

Intracerebral hemorrhage (ICH) is a subtype of stroke associated with high mortality and disability. Basic and clinical research has contributed to our understanding of the complex pathophysiology in ICH. However, questions regarding acute diagnosis, therapeutic decisions, and prognostication of ICH remain unanswered. Molecular biomarkers and imaging markers have revolutionalized diagnosis and treatment of many diseases, such as troponin use in myocardial infarction and magnetic resonance imaging (MRI) scan in ischemic stroke. Therefore, the investigators aim to discovery the potential biomarkers by screening samples of blood, cerebral spinal fluid, urine, saliva, and even tissues (if available) from ICH patients, and imaging markers via serial multimodality imaging scans such as computed tomography(CT), magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), positron emission tomography (PET), etc. These molecular and imaging markers would assist in contributing additional information to current tools for onset warning, diagnosis, therapy monitoring, risk stratification, intervention and prognosis for ICH patients.

To compare the efficacy and safety of neuroendoscopic hematoma removal and standard conservative treatment for patients with spontaneous supratentorial deep intracerebral hemorrhage.

The Chinese Spondyloarthritis Inception cohort (CESPIC) was started 2000 as a prospective, longitudinal, multicentre, nationwide study in China on patients with early SpA including ankylosing spondylitis (AS, also known as radiographic axial spondyloarthritis) and non-radiographic axial SpA. The objectives of CESPIC are to learn about the course of SpA during the very early stage of the disease, to appropriately assess the outcome including radiographic progression of patients after several years of follow-up, to identify outcome predictors, to assess quality of life, function, and costs (direct and indirect costs). CESPIC has been recently expanded to recruit patients with other forms of SpA / conditions associated with SpA: reactive arthritis, acute anterior uveitis, Crohn's disease as well as with psoriasis / axial psoriatic arthritis.
