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 aimed to analyze perioperative information in patients with high-grade squamous intraepithelial lesion (HSIL) undergoing total hysterectomy (TH), offering insights into optimal surgery timing, selecting the operation path, and enhancing surgical operation details.
This study retrospectively evaluated the effect of two different lateral window preparation techniques on peri-implant bone augmentation for patients who underwent lateral sinus floor elevation with simultaneous implant placement using two-dimensional and three-dimensional radiographic results, with special emphasis placed on the stability of the graft material after surgery.
The goal of this retrospective observational study is to evaluate the prognostic value of nutrition assessment tool in advanced cancers. We aim to evaluate the clinical utility of nutrition assessment tool in predicting the clinical outcomes of cancer patients, which would help the clinicians to make tailored decision for this population.
The investigators conducted a retrospective, single-center observational registry upon which one novel scoring system was formed and evaluated for their accuracy in predicting technical success. The investigators reviewed the clinical and angiographic records of 432 patients with 459 CTO lesions who underwent percutaneous recanalization attempts recruited between January 2012 and November 2023. The investigators aims to develop and validate a novel scoring system for predicting CTO-PCI success.
The goal of this clinical trial is to test in Rheumatoid arthritis. The main question it aims to answer are: - To verify the effect of dietary fiber supplementation on reducing the level of inflammation; - To verify the effect of dietary fiber supplementation on improving disease activity and quality of life in patients with rheumatoid arthritis .To verify the effect of dietary fiber supplementation on regulating the production of anti-inflammatory short-chain fatty acid in the gut of patients with rheumatoid arthritis. The experimental group was supplemented with dietary fiber for 12 weeks, and the control group was fed with the Mediterranean diet. Before and after the intervention, 1 tube of 3ml blood and 1 soybean-sized stool were taken and a questionnaire was made
This prospective observational study enrolled adult volunteers for a sleep quality research study through a questionnaire survey distributed via a WeChat two-dimensional code from May 2021 to April 2022. Participants were exposed to flicker stimulation through a light and sound device for a duration of 8 weeks with daily monitoring.
Quantitative flow reserve (QFR), derived from coronary angiography, has shown high accuracy in detecting significant lesions. Ultrasonic flow ratio (UFR), a new development from IVUS, integrates physiological estimation with intravascular imaging. Although both QFR and UFR are effective, there's no conclusive evidence favoring one over the other. The study aims to compare UFR and QFR's diagnostic performance against the conventional FFR standard in detecting significant coronary lesions.
The current study provided an initial investigation of the effect of self-compassion on reducing materialism and explored the basic psychological needs and self-esteem as potential mechanisms. Two studies would be conducted. Study 1 explored the relationships among variables with cross-sectional data, to explore the relationship between self-compassion and materialism, and test the mediating role of basic psychological needs and self-esteem. Study 2 developed a new online self-help self-compassion intervention and conducted a randomized control trial (i.e., intervention group and waitlist group) to further explore the casual effect of self-compassion on materialism, with the mediating effect of basic psychological needs and self-esteem.
The goal of this observational study is to learn about the clinical characteristics and construction of a predictive model in elderly COVID-19 patients. The main question it aims to answer is the main clinical characteristics and risk factors of elderly COVID-19 patients. Participants will not be asked to do any other intervening measure.
Petroclival meningioma (PCM) is a technically challenging lesion. We aimed to analyze the role of various skull base approaches and evaluate the therapeutic outcomes guided by the modified classification. We retrospectively analyzed the clinical characteristics, surgical approaches, outcomes and follow-up data from 179 cases of PCM from January 2011 to December 2020. We modified the previous classification into updated five types with two subtypes: clivus type (CV), petroclival type (PC), petroclivosphenoidal type (PC-S), sphenopetroclival type (S-PC) with two subtypes of S-PC I and S-PC II and central skull base type (CSB). Statistical analysis was performed using IBM SPSS Statistical Package 21.0. The t-test was performed to clinical data comparisons between the two groups and the ANOVA test was used to compare the difference between multiple groups. P < 0.05 was considered statistically significant.
