Clinical trials

This longitudinal observational study aims to evaluate long-term visual adaptation trajectories, optical quality, and patient-reported outcomes in age-related cataract patients following bilateral implantation of multifocal or mix-and-match intraocular lenses (IOLs). Patients will be followed up longitudinally after surgery to systematically assess visual performance and quality of life.

Acute kidney injury (AKI) is a common and serious complication in the ICU. Current diagnostic indicators (such as creatinine and urine output) exhibit significant lag, and specific hemodynamic predictive markers are lacking. The venous return pressure gradient (Pmsf-CVP), based on Guyton's theory, reflects the driving pressure for venous return; however, its value in the early warning of AKI remains unclear. This study aims to investigate the predictive value of the venous return pressure gradient for the onset and progression of AKI in ICU patients, and to clarify its effectiveness as an AKI risk warning indicator. Patients admitted to the ICU within 48 hours with risk factors for AKI (including sepsis, shock, major surgery, underlying diseases, etc.) who have radial artery catheterization and can undergo hemodynamic monitoring will be enrolled. Those undergoing maintenance dialysis/CRRT, ECMO support, or with missing core data precluding calculation of Pmsf-CVP or AKI assessment will be excluded. The venous return pressure gradient (Pmsf-CVP, mmHg) will be measured within 48 hours of ICU admission using the transient stop-flow arm arterial-venous equilibrium pressure method. The primary outcome is to evaluate the association between the venous return pressure gradient level and AKI occurrence. Secondary outcomes include correlation analyses between the venous return pressure gradient level and serum creatinine and urine output within 48 hours of ICU admission, among others.

The intervention group received 12 weeks of continuous remote intervention combined with health education. The control group only received 12 weeks of continuous health education, and the content and frequency were the same as those of the management group. Both groups received instruction at the beginning of the intervention. The intervention group was given priority to continuous walking/running combined with aerobic exercise and swimming. Five to seven sessions per week for 45 minutes each session. Acclimatizations were performed at an intensity of 40%-49% reserve oxygen uptake (VO2R) from weeks 1 to 4, and exercise was performed at an intensity of 50%-59% VO2R from weeks 5 to 12. 5 minutes each of preparation and grooming activities (including joint movement and stretching) for each exercise. Combined with incremental load resistance exercise 2-3 times a week, 8 movements, 2-3 groups each time, repeated 8-10 times/group, with a 2-min rest between groups. The heart rate, RPE (12-13, "fairly easy" to "somewhat laborious") and exercise bracelet were used to monitor the intensity and amount of exercise. The exercise intervention was usually delivered 1-2 h after a meal. The daily medical supervision in the process of management implementation was carried out by trained sports managers through the doctor terminal of "exercise assistant" to collect and monitor the data of the study subjects.

This study aims to understand how differences in the NOTCH2NLC gene affect the symptoms and course of neuronal intranuclear inclusion disease (NIID), a rare inherited neurological disorder. NIID is caused by an abnormal expansion of a GGC DNA repeat in the NOTCH2NLC gene, but members of the same family can have very different repeat sizes and patterns, leading to a wide variety of problems-such as difficulties with memory, movement, sensation, or involuntary body functions. The main goal is to uncover how these genetic differences (repeat length and interruption pattern) contribute to the severity and type of symptoms. The study is being conducted at Sichuan Provincial People's Hospital and will enroll approximately 12 individuals from a single family, including those diagnosed with NIID, family members who carry the genetic change but are not yet sick, and healthy relatives. Participants must be 18-85 years old, able to complete genetic testing and a small skin biopsy, and willing to provide informed consent. Those who are medically unstable or otherwise unable to participate will not be enrolled. The study has both a retrospective part (collecting past medical records) and a prospective follow-up. At the beginning, all participants will have a physical exam, provide a blood sample (for long-read DNA sequencing and RNA sequencing), and undergo a 3-mm skin biopsy to look for disease-related protein deposits. Brain MRI and nerve/muscle electrical tests will also be performed if not done recently. After this baseline visit, everyone will be followed every 6 months for a total of 2 years (5 visits total). Each follow-up visit includes assessments of thinking, memory, movement, autonomic function, pain, and quality of life, along with a neurological exam and repeat imaging/electrical tests as needed. At the final 24-month visit, another blood sample will be taken for RNA sequencing to see how gene activity changes over time. This is an observational study; there is no experimental treatment. Participants will be compensated a total of ¥3,000 across all visits for their time and travel. All data and samples will stay in China and will not be shared internationally.

The goal of this clinical trial is to learn whether early administration of dexmedetomidine can improve autonomic nervous system regulation and clinical outcomes in adult patients with septic shock. It will also evaluate the safety of dexmedetomidine in this population. The main questions it aims to answer are: Does early dexmedetomidine improve sympathetic nervous system activity, as measured by heart rate variability (HRV) and blood pressure variability (BPV)? Does dexmedetomidine reduce endogenous catecholamine levels and vasopressor requirements? Does early autonomic modulation improve organ function and survival outcomes in septic shock? Researchers will compare dexmedetomidine to a placebo (normal saline) to determine whether dexmedetomidine improves hemodynamic stability and prognosis in patients with septic shock. Participants will: Be randomly assigned to receive dexmedetomidine (0.5 μg/kg/h) or placebo by continuous intravenous infusion for 48 hours Undergo continuous ECG and invasive blood pressure monitoring Have blood samples collected at predefined time points to measure inflammatory markers and endogenous catecholamine levels Be assessed for organ function, vasopressor use, and perfusion parameters during the first 48 hours Be followed up for 28-day and 90-day survival outcomes

This multicenter, randomized, open-label clinical trial aims to evaluate the efficacy and safety of taurine as an adjunctive therapy to standard disease-modifying treatments (DMTs) in patients with multiple sclerosis (MS). The study seeks to determine whether oral taurine can reduce the number and volume of new or enlarging MRI lesions, decrease relapse rates, and slow disability progression as measured by the Expanded Disability Status Scale (EDSS). It will also explore the effects of taurine on gut microbiota composition, serum neurodegeneration biomarkers (GFAP and NfL), and cognitive function assessed by MMSE and MoCA. Approximately 80 eligible participants will be enrolled and randomly assigned to either continue standard DMT therapy or receive taurine supplementation in addition to DMTs. The treatment duration will be 24 months, with follow-up visits every 3 months for clinical assessment, blood and stool sample collection, and MRI scans every 6 months. This study aims to provide new clinical evidence supporting taurine as a safe and potentially beneficial adjunctive therapy for multiple sclerosis.

This study aims to compare the efficacy and safety of Sacubitril/Valsartan versus Valsartan in patients with essential hypertension and type 2 diabetic nephropathy over a 12-week treatment period, including two treatment groups, with a total of 297 eligible subjects randomly assigned in a 2:1 ratio to either the experimental group or the control group.Subjects will participate in the study through two phases: the screening period and the follow-up period.The primary outcome measure is the change in systolic blood pressure from baseline after 12 weeks of treatment.

This study aims to explore the role of dagliflozin in preserving the residual renal function(RRF) in peritoneal dialysis (PD) patients.
