Weight regain after intentional short-term weight loss is a common challenge. It often undermines the long-term benefits of obesity treatment. This study is a multi-center 2-arm randomized controlled trial across six regions in China, specifically targeting overweight or obese adults who have recently achieved a short-term weight reduction (≥5% of body weight). The trial will evaluate whether a 10-hour daily Time-Restricted Eating (TRE) regimen can more effectively prevent weight regain compared to standard weight maintenance counseling alone. Both the intervention and control groups will receive the same frequency and intensity of nutritional counseling for weight maintenance; the only difference is that the TRE group will be instructed to confine their daily eating to a self-selected 10-hour window, while the control group has no eating window restriction. In addition to the primary outcome of weight regain, the study will explore potential mechanisms underlying the effects of TRE and assess secondary outcomes including changes in body composition, metabolic health, and quality of life. This study recruits participants from six distinct regions across Eastern, Western, Southern, Northern, and Central China to enhance national representativeness. The study is divided into two phases: the first phase is a 2-month weight loss run-in phase (the screening phase), during which participants will receive standardized lifestyle and diet guidance from trained dietitians. Those who achieve at least a 5% loss of initial body weight by the end of this phase-and maintain a stable weight for approximately three weeks-will proceed to the second phase. In the second phase, participants will be randomly assigned to one of two arms for a 12-month weight maintenance intervention. The Control Arm will receive periodic weight-management nutritional counseling without any eating time restriction, while the TRE Intervention Arm will receive the same guidance plus instructions to follow a daily 10-hour time-restricted eating schedule. This design ensures both groups receive equivalent dietary and lifestyle support, with TRE as the key differential strategy. Following the 12-month intervention phase, participants will be followed for an additional 12 months (without active intervention) to observe longer-term weight outcomes. Data will be collected at multiple time points: baseline (before the weight loss phase), 2 months (end of the weight loss phase and prior to the start of the maintenance phase), 5 months, 8 months, 14 months (end of the weight maintenance phase), as well as 20 months and 26 months (during the post-intervention follow-up). Key outcomes include changes in body weight (to assess weight regain or maintenance), body composition, metabolic health indicators (e.g. blood glucose, lipids), and quality of life measures. To monitor dietary behaviors, participants will be asked to upload meal photos via a designated mobile application with automatic time-stamping, which will be used to assess eating timing and adherence to the prescribed eating window. Body weight will be measured once weekly using Bluetooth-enabled smart scales. To explore potential mechanisms of action, biospecimens (blood and stool) will be collected at baseline, 2 months, 8 months, and 14 months for analysis. In addition, Continuous Glucose Monitoring (CGM) will be performed in a randomly selected subsample of 200 participants (100 from each group) using a standardized device for 14 consecutive days at months 2, 8, and 14. These data will be used to evaluate glycemic stability and adherence to the assigned eating window. Real-time CGM readings will not be disclosed to participants and will not be used to guide individual-level interventions.

This study is a prospective, multicenter, open-label, non-inferiority, randomized controlled trial. A total of 2,000 patients with STEMI (\<24 hours or 7-14 days) or NSTEMI will be recruited from at least 20 centers in China. Eligible patients must have residual DS \< 70% at the culprit lesion assessed by QCA, with optional thrombus aspiration, and TIMI flow of grade 3. Patients will be randomly assigned in a 1:1 ratio to the experimental group or the control group. The planned enrollment period is 36 months, and all patients will be followed up for at least 12 months after randomization, with continued follow-up until the end of the study. The primary outcome is the first occurrence of TLF after randomization, defined as the composite of cardiovascular death, target vessel myocardial infarction, ischemia-driven target lesion revascularization. The study aims to verify whether guideline-recommended standard medical therapy is non-inferior to DES implantation combined with guideline-recommended standard medical therapy in AMI patients with non-severe coronary artery stenosis.

Using Abbott Pressure Wire™X pressure wire test functional indicators, and explore the incidence of coronary microvascular dysfunction (CMD) as assessed by the index of microcirculatory resistance (IMR) in two groups, and its impact on the rate of the composite endpoint of all-cause death and heart failure readmission occurring for the first time within 12 months.

The goal of this clinical trial is to evaluate the effectiveness of the "Heart Voice: Starry Journey" program, a family-centric and Acceptance and Commitment Therapy (ACT)-based digital narrative intervention, in improving psychological flexibility and mental health among primary caregivers of children with Autism Spectrum Disorder (ASD). The main questions it aims to answer are: 1. Does the "Heart Voice: Starry Journey" intervention lead to a greater improvement in psychological flexibility among caregivers of children with ASD, compared to a control group? 2. Does the "Heart Voice: Starry Journey" intervention lead to a greater reduction in symptoms of anxiety and depression among caregivers of children with ASD, compared to a control group? Researchers will compare the intervention group (using the "Heart Voice: Starry Journey" program) with a wait-list control group (receiving usual care and access to the intervention after the trial) to see if the digital intervention is more effective. Participants in the intervention group will: * Use the "Heart Voice: Starry Journey" mobile application over a 6-week period, engaging with interactive stories and ACT-based exercises. * Complete a series of online questionnaires about their psychological flexibility, anxiety, depression, and caregiver burden at the beginning of the study, immediately after the 6-week intervention, and at a follow-up time point (1 months later). Participants in the wait-list control group will: * Continue with their usual care routines during the study period. * Complete the same series of online questionnaires at the same time points as the intervention group.

Breast cancer is one of the most common malignant tumors in women, accounting for the first cancer-related death cause in women. In recent years, the incidence has gradually increased, and the trend is younger. In 2022, the estimated number of new cases of female breast cancer worldwide is 2.389 million, and the estimated number of deaths is 666000. Triple negative breast cancer (TNBC) refers to breast cancer that is negative for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2, accounting for about 10% - 20% of malignant breast tumors. . At present, chemotherapy is still the main means of clinical treatment of TNBC, but the heterogeneity of TNBC in molecular level, pathology and clinical characteristics leads to different sensitivity of patients to different chemotherapeutic drugs, especially the sensitivity of most elderly patients to chemotherapeutic drugs is not high, and the prognosis is poor. The development of immunotherapy in the field of breast cancer has witnessed the continuous deepening of medical understanding of cancer treatment. In the past, breast cancer was often regarded as a "cold tumor" insensitive to immunotherapy, but with the deepening of research, immunotherapy gradually occupied an important position in the treatment of breast cancer. The ongoing research hopes to identify patients who may benefit more from immunotherapy according to their respective tumor immune microenvironment. Its mechanism of action mainly includes two aspects: one is to restore the normal recognition and attack ability of the immune system to tumor cells and break the immune escape mechanism of tumor cells; The second is to stimulate a lasting immune response, so that the immune system can continuously monitor and clear tumor cells. Therefore, this study intends to evaluate the efficacy and safety of Iparomlimab and tuvonralimab combined with olaparib and paclitaxel in the neoadjuvant treatment of early high-risk TNBC with HRD positive. It is planned to enroll 20 subjects. After enrollment, the subjects will receive six cycles of combination therapy with olaparib and docetaxel. Take 3 weeks as a treatment cycle until the treatment termination event specified in the protocol occurs, and the subject will continue to conduct postoperative efficacy and safety visits after the end of treatment. After neoadjuvant treatment, according to the routine treatment process of breast cancer, the subject will receive breast cancer surgery; After surgical treatment, according to the residual breast lesions of the patient, the attending physician and the subject will agree on the subsequent treatment plan.

The MOOP-CAD study program characterizes, for the first time, the pathophysiological processes and molecular mechanisms of coronary atherosclerotic plaque progression by combining in vivo intravascular imaging techniques with circulating immune single-cell multi-omics analysis.

This study is a prospective, single-center, randomized controlled clinical trial. Ninety patients with anterior wall ST-segment elevation myocardial infarction (STEMI) who are planned for primary percutaneous coronary intervention (PCI) within 6 hours of symptom onset will be screened. Patients with inclusion criteria and without exclusion criteria will be randomized into three groups in a 1:1:1 ratio: OCT-guided group, 60 MHz HD-IVUS-guided group, and angiography-guided group after signing the informed consent form. Based on the lesion characteristics detected by imaging in each group, coronary revascularization will be performed for the culprit vessels of myocardial infarction. The TIMI myocardial perfusion frame count (TMPFC) values of the culprit vessels will be recorded immediately after PCI, and secondary prevention medications for myocardial infarction will be administered. Three days after the procedure, a 3.0T cardiac magnetic resonance imaging (MRI) with gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA) delayed enhancement (LEG) scan will be conducted to assess the microvascular obstruction (MVO) area. Patients will be followed in the outpatient clinic visit at 1 month (with a window period of XX days) after discharge, and a repeat cardiac MRI will be performed to determine the presence of MVO and the size of the myocardial infarction.

This is a double-blind, multicenter, randomized, placebo-controlled clinical trial. It is planned to enroll patients admitted with anterior ST-segment elevation myocardial infarction (STEMI) within 6h of symptom onset and undergo primary percutaneous coronary intervention (pPCI). Patients who meet the inclusion criteria and without exclusion criteria were randomized 1:1 into the dexmedetomidine (DEX) group or the placebo (saline) group after signing the informed consent. In the DEX group, intravenous injection of DEX was started immediately after enrollment, covering the entire PCI operation, and the administration was stopped at the end of the pPCI. The administration of saline was the same as those in the DEX group. The primary endpoint was the myocardial infarct size (MIS) as assessed by cardiac magnetic resonance imaging (CMR) at 5±2 days post-STEMI. Based on a superiority design and assuming an 20.0% relative infarct size reduction (from 26.0% to 20.8% with a SD of 13.0%), 250 patients are required to be enrolled, accounting for 20% drop-out (α= 0.05 and power= 80%).
