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.
Histology transformation from non-small cell lung cancer (NSCLC) to neuroendocrine carcinomas (NEC), especially from epidermal growth factor receptor (EGFR) mutant lung adenocarcinoma (LADC) to small cell lung cancer (SCLC), is widely recognized as a rare mechanism for NSCLC to confer tyrosine kinase inhibitors (TKIs) resistance. The probability of its occurrence is about 3-14% in NSCLC patients who are resistant to TKI treatment. In addition to EGFR mutations, NSCLC patients carrying ALK/ROS1 mutations and receiving corresponding TKI treatment may also experience NEC transformation(NET). In a previous study [Pubmed ID: 35609408], the investigators demonstrated that NET also develops in NSCLCs without TKI targets or treatments. This phenomenon could be under-recognized, because re-biopsy was less frequently performed in these patients. The investigators had also shown that p53/Rb inactivation might correlated with NET and should be considered for NET risk prediction. In another retrospective studies, it was found that NSCLC patients with RB1/TP53 dual inactivation mutations had a significantly higher probability of NEC pathological transformation than those without RB1/TP53 inactivation mutations (43 times higher than those without mutations). Therefore, the subgroup of NSCLC patients with tumor suppressor gene RB1/TP53 dual inactivation might have elevated risk for NET. In this study, the investigators proposed to prospectively follow up NSCLC patients with dual RB1/TP53 inactivation (approximately 5% of the total NSCLC). Through prospective and systematic collection of baseline pathological information, clinical treatment process, and imaging data, and as much as possible, repeat pathological biopsies will be performed during disease progression.
This is a non-randomized，open-label，controlled multi-center Phase Ⅰ study to evaluate tolerability, pharmacokinetics, and preliminary efficacy of BM201 injection in combination with radiotherapy in patients with histologically or cytologically confirmed unresectable locally advanced or metastatic solid tumors who have failed standard therapy or are unable to receive standard treatment.
To Evaluate the safety and tolerability of single and multiple intratumoral injections of recombinant oncolytic virus M1 (VRT106) in patients with locally advanced/metastatic solid tumors.
This is a prospective, multicenter, open-label, non-randomized controlled real-world study to explore the efficacy and safety and to accumulate more evidence-based medical data of an antiviral treatment programme for chronic viral hepatitis B with nonalcoholic fatty liver disease. A total of 1500 patients with chronic hepatitis B complicated with nonalcoholic fatty liver disease are divided into test group (1000 patients receiving PEG-IFNα-based antiviral therapy (combined NAs or Peg-IFNα monotherapy) and control group（500 patients receiving NAs monotherapy） according to their treatment intention. Laboratory and medical data from specified follow-up points are collected, and adverse events and drug combinations are recorded detailly. The primary efficacy indicator is HBsAg clearance at 48 weeks of treatment, and the secondary indicators included: (1) HBsAg clearance at 96 weeks of treatment, (2) Cumulative HBsAg clearance at week 24、120、144、168、192、216 and 240; (3) The improvement of liver function level(ALT, AST, TBIL, etc.), blood lipid (TC, TG, LDL-C, HDL-C, etc.), fasting blood glucose, insulin resistance index (HOMA-IR), controlled attenuation parameter, body mass index , liver stiffness measurement, liver histological fibrosis, FIB-4 index from baseline; (4)Incidence of liver cirrhosis and hepatocellular carcinoma during follow-up. The security assessment includes adverse events, vital signs, and imaging.
This study will investigate the impact of exercise on gastrointestinal function in peritoneal dialysis patients.
Ischaemic heart disease (IHD) and degenerative brain disease are two major sources of death and disability affecting all countries. While the consequences of obstructive disease in major vessels supplying blood to both organs have been widely documented, less attention has been paid to disease processes affecting the microcirculation that may affect cardiac and cerebral function. Yet, over the last decade significant progress has been made in understanding the substrate of microvascular disease in both organs. In the heart, arteriolar thickening and capillary rarefaction that reduce the conductance of the microvasculature and its ability to vasodilate in response to increased myocardial oxygen demands constitute the leading cause of coronary microvascular dysfunction (CMD). In the brain, concentric hyaline thickening of deep penetrating small arteries (arteriolosclerosis) with associated fibrosis of the vessel wall constitutes the most frequent substrate for cerebral small vessel disease (CSVD). Of note, both CMD and CSVD share common risk factors, such as age, hypertension, and diabetes.3 These factors might have a common effect on the microvascular domain of cardiac and cerebral vascular beds. Although a potential link between both conditions has been hypothesized based on the similarities between pathological changes and risk factors, advance in knowledge exploring this has been hampered by lacking objective evidence of CMD and pathological brain changes indicative of CSVD in prior research studies. Thus, the relationship between CMD and CSVD is unknown. The main objective of this study was to analyse the relationship between cerebrovascular disease and CMD in patients with atherosclerotic coronary artery disease (CAD).
A randomized controlled clinical study was conducted to elucidate the relationship between the lower extremity biomechanics of patients undergoing early gait training after ACLR surgery.The relationship between the biochemical characteristics of cartilage and the biomechanical risk index were proposed to providing exercise guidance and training for middle-aged people and it is suggested that it can prevent and reduce the risk of cartilage degeneration early after operation.
Metabolic bone disease of prematurity (MBDP) is caused by insufficient content of calcium, phosphorus, and organic protein matrix in preterm infants or bone metabolism disorder, which is one of the complications affecting the quality of life of preterm infants. The early symptoms of MBDP are insidious, and there is no unified and clear diagnostic method. The diagnosis is mostly based on typical clinical manifestations and X-ray findings, but at this time, bone mineral density has decreased significantly, so early detection and diagnosis are difficult. Studies have shown that exosomal micrornas have biological characteristics and targeting specificity, and can be used as new molecular diagnostic markers for diseases. Several studies have reported the use of plasma or serum microRNAs as molecular markers for early prediction of bone diseases. In our previous study, we extracted plasma exosomes from preterm infants for high-throughput sequencing of microRNAs, and identified differentially expressed micrornas related to bone metabolism. In this study, exosomes were used as carriers, and digital PCR was used to verify the specificity and sensitivity of plasma exosomal microRNA as biomarkers of MBDP in a large sample size. The above biomarkers were compared and verified before and after treatment in children with MBDP. Further revealing plasma exosomal microRNA as a biological indicator for evaluating the efficacy of MBDP may improve the diagnostic level of MBDP, improve the outcome and prognosis of very low birth weight preterm infants, thereby improving global health and reducing socioeconomic costs.

1. We collect lung tissues from patients with different ages and confirm that KLK8 expression is positively correlated with age. 2. We collect peripheral blood from patients with different ages and duration of mechanical ventilation to explore the correlation between the degree of endothelial/epithelial damage, age and duration of mechanical ventilation.
