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.
This study is a single-arm, open clinical trial.This trial consists of two phases, dose-escalation and expansion, and the study process is divided into: a screening period, a sampling and production period, a lung-clearing pretreatment period, a treatment and observation period, and a follow-up period.
The purpose of this research is to evaluate the efficacy of multiple sessions of theta-gamma cross-frequency transcranial alternating current stimulation in patients with methamphetamine (MA) use disorders.
Aerobic exercise and resistance exercise are two types of exercise commonly used in physical conditioning. Compared to aerobic exercise, a combination of aerobic and resistance exercise has been linked to a greater reduction in hemoglobin A1c (HbA1c) among patients with type 2 diabetes (T2D). However, it is not clear that in a concurrent aerobic-resistance training session, whether the orders of the two types of exercise could act differently in glucose metabolism. This pilot randomized trial aims to investigate the effect of the sequence of exercise modalities (aerobic-resistance vs resistance-aerobic in a training session) on glycemic control among T2D patients following an 8-wk intervention period. The trial also aims to compare the effects of the two different sequences in blood pressure, sleep quality, and lower limb muscle strength among the T2D population.
Accurate preoperative AKI risk prediction is of great significance for improving patient outcomes. The use of preoperative NT-proBNP can provide a more precise assessment of the body's fluid load status, guide intraoperative and postoperative fluid management, and thus reduce fluid related postoperative complications. Given the potential association between ERAS and increased postoperative AKI, we hypothesize that preoperative NT-proBNP may be associated with the development of postoperative AKI in ERAS, and can improve the prediction of AKI beyond traditional clinical risk factors. This study aims to validate this hypothesis and provide evidence for using NT-proBNP to assess AKI risk before non cardiac surgery. Improve the predictive ability of clinical predictive models and optimize ERAS protocols to prevent postoperative AKI.
Patients with salivary gland carcinoma were divided into groups according to HER2, NTRK, AR, TROP-2, etc. Patients in different groups were given precision targeted therapy or chemotherapy to evaluate the efficacy (ORR rate, etc.) and safety of precision neoadjuvant or conversion therapy.
This study will help to determine the main clinical symptom differences between patients of different ages, discover the family genetic predisposition of patients of different ages, and obtain the differences in pathological characteristics of patients of different ages, so as to provide help and basis for more accurate and earlier prevention and treatment of colorectal cancer.
To study the effectiveness of ACB and iPACK block with liposomal bupivacaine for postoperative analgesia in patients undergoing knee arthroplasty
Acupuncture has been widely used in the treatment of Premature Ovarian Insufficiency(POI), but the selection of acupoints is indeterminate and lacks biological basis.In recent years,some studies suggested the "acupoint sensitization",that is,changes such as pain sensitivity and heat sensitivity appear on the acupoints under disease state.The biological characteristics of acupoints can reflect the state of local tissue and might be a potential factor for guiding acupoint selection. This study aims to compare the temperature and pain threshold of acupoints between POI patients and the healthy population.At the meantime,clinical diagnosis of POI is based on clinical symptoms and Follicle Stimulating Hormone (FSH).However,FSH fluctuates so much that prediction accuracy is not high and clinical application is limited.Therefore, given the lack of proper diagnostic accuracy in POI and the concept of "acupoint sensitization",it is necessary to summarize the changes of biological characteristics of related acupoints under physiological and pathological conditions as an auxiliary means to improve the diagnostic rate of POI.
This is a multi-center, double blind, prospective, placebo controlled, randomized phase III clinical trial to further validate the efficacy and safety of neoadjuvant pyrotinib combined with chemotherapy in HR-positive/HER2-low (IHC 2+/FISH-negative) early breast cancer
There are still a large number of severe spinal deformity cases which would keep progressing without treatment. These patients not only have severe appearance deformity, but also suffer from cardiopulmonary compression, reduced abdominal volume, and even spinal cord injury. It is crucial to provide safe and effective surgical intervention for these patients. The corrective surgery with 3-column osteotomy is reported to be an effective surgical strategy for severe spinal deformity. However, due to the great corrective stress on the rods, there is an increased number of patients requiring revision surgery due to rod fracture (3.7%-15%). In patients with 3-column osteotomy, the osteotomy area and the upper and lower adjacent segments are mostly stress-concentrated areas, and the rod is prone to fatigue fracture. Therefore, it is necessary to reinforce the osteotomy area and adjacent segments to reduce the risk of rod fracture. Our previous study found the risk of rod fracture could be reduced by using satellite rods with duet connectors or dominos. However, in the traditional satellite rod technology, the connection of the main rod and the satellite rod rely on the traditional single slot screw and duet connectors. The two are separated and not a whole in the mechanical structure. The stability of the fixation is relatively insufficient, and stil deserves room for improvement. Based on the traditional duet connectors, we further invent a novel dual-headed pedicle screw, which is an combination of traditional single slot screw and duet connector. Compared with the traditional duet connector, the novel dual-headed pedicle screw theoretically has stronger stability between the main rod and satellite rod, due to its integration of screw and connector. Hence, the purpose of this study is to verify the strong stability of the novel dual-headed screw by biomechanical study in cadavers performed with long spinal fusion (T12-pelvis) with L3 pedicle subtraction osteotomy (PSO). And to further investigate its effectiveness in severe adult spinal deformity patients receiving corrective surgery with PSO. If the biomechanical properties and clinical effects of the novel dual-headed screw have been confirmed, the promotion of the product has great prospects in the world. The severe spinal deformity patients would benefit from this study when they receive spinal corrective surgery with 3-column osteotomy, using satellite rods technology by this novel dual-headed screw.
