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.
The field of research for this study is tissue engineering and the utilization of a small intestinal submucosa graft as a substitute biomaterial for conventional buccal mucosa in substitution urethroplasty of anterior urethral strictures.
Comparison of aerosol inhalation and intravenous glucocorticoid in the treatment of severe AECOPD-------Multicenter, prospective, randomized, controlled clinical study
This clinical trial aims to learn about the efficacy of MLYAAT-1002® (a proprietary anti-aging complex, MLYAAT is short for "multi-layer anti-ageing technology" ) in female subjects who have newly received the rejuvenation treatment by comparing visual clinical scores, skin attributes measurement and image analysis.
Cryptococcus neoformans and C. gatti are important causes of central nervous system (CNS) infections with significant mortality, remaining a great public health challenge worldwide. Commonly seen as an opportunistic infection in adults with HIV/AIDS, cryptococcal meningitis (CM) accounts for 15% of HIV-related mortality globally [1]. In addition, a growing number of non-HIV CM patients have been observed in recent years with fatality approaching 30% in some areas [2,3]. It occurs in both those with natural or iatrogenic immunosuppression, as well as the apparently immunocompetent individuals. Approximately 65-70% of non-HIV CM patients were without any predisposing factors, particularly in the East Asia [4,5]. With the increasing number of hematopoietic stem cell transplantation, solid organ transplantation recipients and administration of immunosuppressive and corticosteroids agents, this illness will assume even greater public health significance. Current Infectious Disease Society of America (IDSA) guideline suggest the use of combination antifungal therapy: normal dose amphotericin (0.7-1mg/kg/day) combined with flucytosine for a minimum of 4 weeks, followed by fluconazole (600-800 mg/day) for a minimum of 10 weeks in total for HIV patients [6]. However, for non-HIV and immunocompetent patients, the treatment remains controversial. IDSA guideline recommended that the treatment of non-HIV patients could refer to the treatment of HIV patients. That is, amphotericin B combined with flucytosine is still administered in the induction period. However, as amphotericin B have nonspecific effect on ergosterol, it has strong side effects (hepatorenal toxicity, electrolyte disorder, anemia, ventricular fibrillation, etc.). Therefore, the dose of amphotericin B may not be appropriate for Asian patients due to the different drug metabolism and pharmacokinetic. In the prospective studies of Bennett[7] and Dismuke[8], low dose amphotericin B (0.3 mg/kg/d) combined with flucytosine achieved response rates of 66% and 85% at 6 weeks, respectively. A similar conclusion was also extracted from a large multicenter retrospective study that low dose amphotericin B (<0.7 mg/kg/d) combined with flucytosine for a minimum of 2 weeks, followed by fluconazole could achieve a response rate of 84%, indicating that the efficacy of low dose amphotericin B (< 0.7 mg/kg/d) may be equivalent with normal dose in non-HIV patients. Therefore, we plan to conduct a prospective, multicenter, open-label randomized controlled study to compare the efficacy and safety of normal dose amphotericin B (0.7 mg/kg/ d) and low dose amphotericin B (0.5 mg/kg/d) in the initial antifungal treatment for non-HIV cryptococcal meningitis patients.
This study is done to test the safety and preliminary efficacy of drug ND-003 tablets in patients with solid tumors. ND-003 is a highly potent and selective small molecular inhibitor of NTRK (neurotrophic receptor tyrosine kinase) and RET (rearranged during transfection). The study also investigates how the drug is absorbed and processed in the human body.
There is limited research on aspiration pneumonia-induced ARDS (Acute Respiratory Distress Syndrome), and currently there is a lack of studies on corresponding biomarkers and pathogenic mechanisms. We hypothesize that pH and amylase in BAL (Bronchoalveolar Lavage) may serve as candidate biomarkers for inhalation-induced ARDS, while changes in different cytokines may provide clinical evidence for studying its pathogenic mechanisms.
The goal of this observational study is to to evaluate the efficacy and safety of Venetoclax in combination with DA60(daunorubicin 60 mg/m2/d for 3 days, and cytarabine 100 mg/m2 every 12 h for 7 days) induction and HD-AraC(cytarabine 3 g/m2 every 12 h for 3 days) consolidation, in young patients with newly diagnosed acute myeloid leukemia (AML).
The goal of observational study is to learn about the outcomes of the participants. The main questions it aims to answer are: 1. ESD additional postoperative radiotherapy in patients with non healing SESCC overall survival (OS) and disease-free survival (DFS) 2. The adverse events (AE) of additional radiotherapy after ESD for non-curative SESCC patients were counted, and its safety was evaluated. Participants will receive radiation therapy as necessary.
The study is a single-center, observational design with a 12-month duration. Approximately 100 Chinese adult (18-65 years old) and adolescent (12-17 years old) with moderate to severe house dust mite (HDM) allergic rhinitis (AR) with or without allergic asthma (AA) who are newly prescribed ACARIZAX® will be recruited for evaluation of the relevance of measurement instruments. The instruments referred to three patient-report scales of allergic rhinitis symptom and quality-of-life including the Daily symptom score (DSS), Standardised rhinoconjunctivitis quality-of-life questionnaire [RQLQ(S)], and Visual analogue scale (VAS). Other data will be collected to evaluate the effectiveness and safety of ACARIZAX® under real-world clinical practices.
The clinical feasibility of 18F-FMBG cardiac PET imaging will be observed in sympathetic nervous system activity in patients with heart failure, predicted cardiac events, guided ICD implantation, and evaluated therapy efficiency.
