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 goal of this observational study is to test the application value of 3D bioprinting technology in personalized treatment of pancreatic cancer. The main questions it aims to answer are: - Can 3D bioprinting technology be successfully applied to establish preclinical models of pancreatic cancer? - Can 3D bioprinted preclinical models of pancreatic cancer be applied to personalized treatment of pancreatic cancer? Participants will have tumor tissue collected to extract primary tumor cells for the establishment of in vitro preclinical models, which will be used for drug sensitivity testing.
The purpose of this study is to assess the progression free survival (PFS) in the real-world settings of polatuzumab among Chinese diffuse large B cell lymphoma (DLBCL) participants.

Bipolar disorder has a high hospitalization rate, suicide rate and disability rate, and cognitive dysfunction is one of the core clinical symptoms of bipolar disorder. Cognitive recovery has become a new target and a new target for clinical treatment. In recent years, gut microbiome has been recognized as one of the neuropathological mechanisms of bipolar disorder. This study aims to study the effect of probiotics on cognitive function in stable bipolar disorder patients and the possible mechanism of action. A total of 100 patients with stable bipolar disorder were enrolled into the control group and the experimental group in a random double-blind way to evaluate the intestinal microecology, clinical symptom improvement, cognitive function and side effects before and after treatment between the two groups, and further explore the possible mechanism of action of the experimental drug.
The goal of this clinical trial is to evaluate the efficacy of investigator's choice of chemotherapy, either alone or in combination with everolimus, in treating patients with locally recurrent inoperable or metastatic triple-negative breast cancer, luminal androgen receptor (LAR) subtype with PI3K/AKT/mTOR (PAM) pathway mutation, as the first-line treatment.
This study aimed to evaluate the pharmacokinetics, pharmacodynamics, and safety of SHR4640 tablets in subjects with moderate renal insufficiency and healthy subjects, and to explore the relationship between renal function (e.g., eGFR) and SHR4640 pharmacokinetic and pharmacodynamic parameters.
Colorectal cancer (CRC) is one of the most common gastrointestinal tumors. According to the latest cancer report, the incidence and mortality rates of CRC are both ranked top 5 among malignant tumors worldwide and continue to rise. Patients who receive treatment in the early stage (stage I) have a 5-year survival rate of approximately 90%. However, for high-risk stage II and III colorectal cancer patients, the 5-year survival rate is only 40%-70%, and almost half of the patients experience postoperative recurrence and metastasis. Evidence suggests that Stage III CRC patients can benefit from standard adjuvant chemotherapy. It is worth noting that some high-risk stage II patients, especially those with T4N0, have a poorer prognosis compared to stage IIIA (T1-2N+). Adjuvant chemotherapy is now also recommended for postoperative cases of high-risk stage II CRC. Given the high effectiveness of the three-drug FOLFOXIRI regimen in treating metastatic CRC and the success of adjuvant chemotherapy in treating pancreatic cancer, the combination of 5-fluorouracil, oxaliplatin, and irinotecan may have a synergistic effect. Extensive study results have shown that: (a) The status of ctDNA methylation after surgery is significantly correlated with patient prognosis, and patients who are positive for ctDNA methylation in the first 1-4 weeks after surgery (before adjuvant chemotherapy) have a poor prognosis. (b) Patients who are ctDNA methylation positive in the first 1-4 weeks after surgery (before adjuvant chemotherapy) can benefit from adjuvant chemotherapy, and achieving ctDNA methylation negativity through adjuvant chemotherapy significantly improves patient prognosis. This project focuses on exploring the optimized mode of postoperative adjuvant chemotherapy for high-risk stage II and III CRC guided by ctDNA methylation, which has high scientific and innovative value. This multicenter, prospective, and randomized controlled cohort study uses a single-tube methylation-specific quantitative PCR (mqMSP) detection, which detects 10 different methylation markers and can quantitatively analyze plasma samples containing tumor DNA as low as 0.05%. This study will use this ctDNA methylation detection technology to perform quantitative detection of ctDNA methylation in the plasma of enrolled patients, and explore the effect of different chemotherapy regimens on ctDNA clearance rate and the prognostic value for ctDNA positive patients. We hope to screen out high-risk populations for recurrence through postoperative ctDNA testing, and administer more intensive chemotherapy regimens (chemotherapy upgrading) as early as possible to improve ctDNA clearance rate and patient prognosis.
In recent years, due to the frequent occurrence of kidney disease and diabetes, the number of patients entering maintenance hemodialysis is increasing. With the economic development and dialysis quality improving year by year, the survival time of uremic patients is significantly prolonged, and the hazards of various complications are increasingly prominent. Cognitive impairment is a common complication of maintenance hemodialysis patients, and its specific mechanism is not yet clear. Type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) are independent risk factors for cognitive impairment. The prevalence of cognitive impairment is higher in patients with type 2 diabetes and advanced chronic kidney disease, especially in patients with diabetes and end-stage renal disease (ESKD). T2DM and ESKD independently increase the risk of cerebrovascular disease and cognitive impairment. However, the relationship between diabetes mellitus and cognitive function in maintenance hemodialysis patients is unclear. However, compared with the general population, patients with type 2 diabetes mellitus (T2DM) and patients with advanced chronic kidney disease (CKD) had more severe brain atrophy, and the severity of white matter lesions on brain MRI increased. To sum up, the study of cognitive dysfunction is very important in maintenance hemodialysis patients with diabetes. It is urgent for us to explore the changes of cognitive impairment and brain magnetic resonance in maintenance hemodialysis patients with diabetes, so as to help detect brain cell damage and improve the survival rate and quality of life in the early stage of the disease.
Colorectal cancer is the third most common malignant tumor. Radical resection is the mainstay of treatments for non-metastatic colorectal cancer. In case of traditional laparoscopic surgery, inexperienced assistants are likely to cause side injuries and interfere surgeon due to limited operating space. Reduced-port laparoscopic surgery has only 3 ports for surgeon and observer, and the surgeon completes the surgery independently, which increases the difficulty of the operation. However, reduced-port laparoscopy has some potential advantages and applications. Reduced-port laparoscopic surgery avoids the prolongation of the operation time and parainjury caused by inexperienced assistant. Reduced-port laparoscopy reduces some surgical incisions, resulting in less pain and faster recovery. Reduced-port laparoscopy also reduces the consumables, human resources and medical expenses. This study aims to evaluate the curative effect and safety of reduced-port laparoscopic surgery versus conventional laparoscopic surgery for resectable colorectal cancer.
