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.
Dexmedetomidine (DEX) sedation is widely used in deep brain stimulation implantation (DBSI) of patients With Parkinson's disease. However, intraoperative application of DEX may affect the discharge activity of deep brain nuclei and reduce the discharge frequency of Subthalamic nucleus (STN) neurons. At present, there is still a lack of prospective intervention research to explore the optimal dose that does not affect MER mapping in patients with Parkinson's disease. The present study uses the Dixon and Massey up-and-down method to analyze the EC50 of DEX in patients with PD undergoing STN-DBS sedation, to clarify the balance meets the sufficient comfort of patients without affecting the accurate target of MER and the optimal dosage of DEX for boundary recognition.
To evaluate the pathological response rate of pamiparib combined with abiraterone acetate in neoadjuvant therapy for surgically resectable high-risk or very high-risk prostate cancer after radical prostatectomy
This is a prospective, single-arm, open-label, dose-finding and dose-expansion study that evaluates the safety, tolerability, PK, and anti-tumor efficacy of LCAR-BCDR cell preparations in relapsed/refractory multiple myeloma subjects who received adequate standard therapy.
Refractory hepatitis B is to point to although standard application nucleoside (acid) analogue treatment undertakes primary treatment and two strengthen treatment, but existence is persistent viremia. Currently, there is no consensus on salvage therapy for patients who remain virus-positive after a second round of antiviral therapy. This is the first multicenter, prospective, parallel controlled, open-label cohort study to compare the efficacy and safety of TDF/TAF combined with ETV1.0mg regimen versus continuation of the original regimen in the treatment of refractory hepatitis B.
The purpose of this study is to evaluate the efficacy and safety of venetoclax combined with azacitidine regimen for newly diagnosed T-ALL patients.
The investigators evaluate the activation and connectivity of patients' motor regions in the acute phase of ischemic stroke by fNIRS.
this study is to clarify the epidemiological characteristics of Omicron variant infected persons in Shanghai, such as distribution characteristics, host and clinical characteristics, disease outcome and risk factors. especially asymptomatic infections.
The emergence of a novel coronavirus(SARS-CoV-2) in late 2019 has resulted in a global epidemic of the infectious condition COVID-19. Since March 2022, the Omicron mutant has caused widespread transmission in Shanghai, China, and is characterized by the majority of asymptomatic patients. Although showing no obvious symptoms, the asymptomatic patients have high transmissibility because of high viral loads in their oropharynx and nasopharynx. Thereforeļ¼this study puts forwards the hypothesis that local flushing treatment in the sino-nasal and mouth cavity can reduce the viral load to reduce their transmissibility. Nasal Irrigation and gargling is a safe and commonly used mechanism to treat a variety of sinonasal diseases including sinusitis, rhinitis, and upper respiratory tract infections. Povidone-iodine(PVP-I) is a water-soluble complex of povidone, a carrier molecule, and iodine, which has powerful microbicidal activity. Also, recent evidence of in-vitro virucidal action of povidone-iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2) has been supported. Therefore, the study is designed to assess the virucidal effect of nasal irrigation and gargling with PVP-I against SARS-CoV-2 located in the throat. The hypothesis was that the treatment would be effective in improving the negative conversion rate of SARS-CoV-2 nucleic acid on day 10.
Evaluate the efficacy and safety of tislelizumab in combination with anlotinib in patients with stage III and IV PSC .
Postoperative nausea and vomiting (PONV) is particularly one of the most common complications after laparoscopic sleeve gastrectomy (LSG). It can lead to serious adverse events and delayed activity, and prolong the time of rehabilitation and discharge. Numbers of studies have been focused on identifying risk factors and therapies of PONV. Unfortunately, there' no consistent comments for PONV prevention in women after LSG. Notably, Zusanli (ST36) acupoint and anisodamine have been evidenced to treat various gastrointestinal conditions. The primary outcome of this study was to evaluate the impact of anisodamine injection in ST36 on PONV in women following bariatric surgery.
