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.
A multi-center, randomized, double-blind, positive drug-controlled clinical study to evaluate the safety and efficacy of Botulinum Toxin Type A for Injection in the treatment of moderate to severe glabellar lines
Machine learning algorithms are applied to discover gut flora markers that predict the clinical efficacy of acupuncture, so as to screen the appropriate population for acupuncture and optimise the allocation of healthcare resources.
ABSTRACT Background and objective: To establish a ultrasound radiomics machine learning model based on endobronchial ultrasound (EBUS)to assistdoctors in distinguishing between benign and malignant diagnoses ofmediastinal and hilar lymph nodes. Methods: The clinical and ultrasonic image data of 197 patients wereretrospectively analyzed. The radiomics features were extracted by EBUS.based radiomics and dimensionality reduction was performed on thesefeatures by the least absolute shrinkage and selection operator (LASSO)EBUS-based radiomics model was established by support vector machine(SVM).205 lesions were randomly divided into a training group (n=143)and a validation group (n=62). The diagnostic efficiency was evaluated byreceiver operating characteristic (ROC).Results: A total of 13 stable features with non-zero coefficients wereselected. The support vector machine (SV) model exhibited promisingperformance in both the training and verification groups. In the traininggroup, the SVM model achieved an area under the curve (AUC) of 0.892(95% CI: 0.885-0.899), with an accuracy of 85.3%, sensitivity of 93.2%and specificity of 79.8%.In the verification group, the SVM modeldemonstrated an AUC of 0.906 (95% C: 0.890-0.923),along with anaccuracy of 74.2%,sensitivity of 70.3%, and specificity of 74.1% Conclusion:EBUS-based radiomics model can be used to differentiatemediastinal and hilar benign and malignant lymph nodes. The SVM modeldemonstrates superiority and holds potential as a diagnostic tool in clinical practice
Phase I clinical study to investigate the safety and tolerance of therapeutic BCG in postoperative adjuvant therapy in subjects with moderate to high-risk non-muscular invasive bladder cancer (NMIBC)
To establish a real-world clinical cohort and database of Azvudine in the treatment of SARS-CoV-2 infection, and to provide stable and reliable evidence for the clinical efficacy and safety evaluation of azvudine in the treatment of SARS-CoV-2 infection.
The goal of this clinical trial is to verify the effectiveness and safety of the low load blood flow restriction training program. The intervention effect, tolerance and compliance of low load blood flow restriction training and progressive resistance training on lung cancer patients complicated with sarcopenia during chemotherapy will be compared, in order to provide new ideas for improving or reversing sarcopenia. The main questions it aims to answer are: Can low load blood flow restriction training improve sarcopenia in chemotherapy induced lung cancer patients? Which training method is more effective and tolerable between low load blood flow restriction training and progressive resistance training? Participants will be randomly divided into 3 groups： 1. Routine care group (Control group, CON): The researchers will provide participants with regular exercise and dietary guidance. 2. Low load blood flow restriction group (LL-BFRT): The researchers will provide participants with a low load blood flow restriction training program constructed by our research group. 3. Progressive resistance training group (PRE): The researchers will provide participants with progressive resistance training.
The DNA methylation targets in preoperative plasma samples of the subjects will be detected by the multi-gene methylation test (ColonAiQ), and the test accuracy will be evaluated by compared with the clinical diagnosis evidence.
The efficacy of three different alimentary reconstruction methods after proximal gastrectomy will be investigated in this study in a prospective, multicenter, randomized controlled trial.
This is a cross-sectional obsessional study. This study aims (1) to investigate the relationship between sternocleidomastoid muscle recruitment and diaphragm thickness fraction during increasing inspiratory resistance in healthy adults; (2) to compare diaphragmatic and sternocleidomastoid muscle recruitment patterns with and without a standard diaphragmatic breathing instruction with increasing inspiratory resistance in healthy adults. Participants will be asked to breathe through a pressure threshold inspiratory loading device under different inspiratory resistances with and without a standard diaphragmatic breathing instruction. sternocleidomastoid muscle activity will be measured with surface electromyography, and diaphragm thickness will be assessed with ultrasonography.
This was a multicenter randomized controlled study. 66 post-stroke patients with pharyngeal dysphagia were randomly allocated to the observation group or the control group. Both groups were provided with comprehensive rehabilitation including routine rehabilitation and swallowing function training. Besides, the observation group additionally underwent the stellate ganglion block (SGB). At admission and after 20-day treatment,Yale Pharyngeal Residue Severity Rating Scale, video fluoroscopic swallowing study (VFSS), Functional Oral Intake Scale, and Rosenbek penetration-aspiration scale (PAS) were used to assess swallowing function.
