This real-world observational study aims to evaluate the effectiveness, safety, and therapeutic drug monitoring (TDM) of liposomal amphotericin B (L-AmB) in solid organ transplant recipients with invasive fungal disease (IFD). IFD is a major cause of morbidity and mortality in transplant recipients because of long-term immunosuppressive therapy and increased susceptibility to opportunistic fungal infections. This is a single-center ambispective cohort study conducted at Sichuan Provincial People's Hospital. The study includes a prospective cohort of solid organ transplant recipients receiving L-AmB therapy and a historical control cohort treated with alternative systemic antifungal regimens. Clinical management and treatment decisions will be determined by treating physicians according to routine clinical practice, and no study-specific intervention will be introduced. The study will collect information on demographic characteristics, transplant type, immunosuppressive regimens, fungal pathogens, infection sites, antifungal treatment strategies, laboratory findings, and clinical outcomes. Particular attention will be given to renal safety, electrolyte abnormalities, and therapeutic drug monitoring of liposomal amphotericin B. Plasma concentrations of L-AmB, treatment modifications, temporary treatment discontinuation, and concentration-related safety and effectiveness outcomes will be recorded during antifungal therapy. The primary outcomes are the 28-day clinical response rate and 84-day all-cause mortality. Secondary outcomes include mycological clearance, acute kidney injury, electrolyte abnormalities, breakthrough fungal infection, treatment discontinuation due to adverse events, liposomal amphotericin B plasma concentrations, and the associations between L-AmB exposure and clinical outcomes or treatment-related toxicities. The study is expected to provide real-world evidence regarding the effectiveness, safety, and pharmacokinetic characteristics of L-AmB in transplant recipients, support optimization of antifungal treatment strategies, and inform individualized dosing and monitoring approaches in this high-risk population.

This multicenter, prospective, open-label, randomized controlled trial will evaluate whether platelet aggregation function-guided de-escalation of antiplatelet therapy is non-inferior in efficacy and superior in safety compared with standard dual antiplatelet therapy in patients with acute minor ischemic stroke or high-risk transient ischemic attack who are sensitive to clopidogrel. Participants who present within 48 hours of symptom onset and meet the eligibility criteria will receive loading doses of clopidogrel and aspirin, followed by platelet aggregation function testing. Eligible clopidogrel-sensitive participants will be randomized to receive either 7 days of dual antiplatelet therapy followed by clopidogrel monotherapy or standard 21-day dual antiplatelet therapy followed by single antiplatelet therapy. The primary efficacy outcome is new stroke within 90 days after randomization.

This is a single-center prospective observational study designed to evaluate the effectiveness of multimodal muscle ultrasound for the assessment of sarcopenia in kidney transplant recipients. Adult patients undergoing kidney transplantation will undergo both muscle ultrasound and bioelectrical impedance analysis (BIA) at predefined time points before and after transplantation. The primary objective is to evaluate the diagnostic performance of muscle ultrasound for sarcopenia assessment, including its correlation and agreement with BIA-derived skeletal muscle index (BIA-SMI), as well as its diagnostic accuracy. Secondary objectives include describing the longitudinal changes in sarcopenia prevalence and muscle-related parameters from the pre-transplant period to 1 year after transplantation. The study aims to provide evidence for a convenient, noninvasive, radiation-free, and reliable method for sarcopenia assessment in kidney transplant recipients.

This is a multicenter real-world observational cohort study designed to evaluate the effectiveness and safety of sulbactam-durlobactam in patients with carbapenem-resistant Acinetobacter baumannii (CRAB) infections. Patients receiving sulbactam-durlobactam will be compared with those receiving other anti-CRAB regimens during the same period. The primary outcomes are 28-day all-cause mortality and clinical failure. Secondary outcomes include microbiological clearance, recurrence, length of hospital and ICU stay, duration of mechanical ventilation, and adverse events. To reduce confounding inherent in observational studies, propensity score methods, including matching and inverse probability weighting, will be applied. A nested therapeutic drug monitoring (TDM) sub-cohort will be established to explore the relationship between drug exposure and clinical outcomes.

The goal of this clinical trial is to assess the viability of dexmedetomidine hydrochloride nasal spray under minimal or no supervision and to further investigate novel clinical applications for this medication. This study aims to investigate the following aspects: the incidence of adverse respiratory and circulatory events requiring medical intervention following the administration of dexmedetomidine nasal spray for pre-anesthetic sedation, its sedative efficacy and onset time, and its impact on the quality of post-anesthesia recovery and the occurrence of postoperative delirium. Researchers will compare dexmedetomidine hydrochloride nasal spray to a placebo (a look-alike substance that contains no drug) to see the incidence and severity of adverse events following administration. Participants will receive either dexmedetomidine nasal spray or a placebo 45 minutes before anesthesia induction. The blinded assessor will continuously monitor and record vital signs, adverse events, and the level of sedation. More importantly, observations and records should be made for respiratory and circulatory events that require medical intervention. A follow-up assessment will be conducted within three days after the operation to evaluate the incidence of postoperative delirium and patient satisfaction.

The main questions it aims to answer are: How effective is red yeast rice in treating PCOS? Does the indole metabolic pathway of gut microbiota play a crucial role in the improvement of PCOS symptoms by red yeast rice? Participants will take 6 grams of red yeast rice daily for 6 months, and records will be kept of their PCOS clinical symptoms and indicators before the intervention, at the 3rd month post-intervention, and at the 6th month post-intervention. Additionally, biological samples from feces and serum will be collected at these time points.

As infection control improves and circulation stabilizes, treatment de-escalation of septic shock begins, accompanied by fluid redistribution from interstitial spaces to the vasculature, increasing cardiac volume load. Synthetic recombinant human BNP (rh-BNP) plays a role in inducing vasodilation, particularly in the venous system, alleviating cardiac congestion, and enhancing natriuresis and diuresis. Thus the investigators designed a single-center, prospective physiological study to evaluate the efficacy of standard rh-BNP infusion in reducing venous return and enhancing fluid removal, with a secondary objective of assessing the maintenance of perfusion pressure and tissue perfusion.

Chronic Liver Disease (CLD) is associated with significant cognitive dysfunction, including hepatic encephalopathy (HE), which is driven by systemic inflammation and blood-brain barrier (BBB) disruption. Perioperative Neurocognitive Disorders (PND), comprising postoperative delirium (POD) and postoperative cognitive dysfunction (POCD), further exacerbate these impairments, particularly in cirrhotic patients undergoing major surgery. However, the mechanisms linking systemic inflammation, BBB dysfunction, and PND remain poorly understood. This study aimed to investigate perioperative cognitive changes and inflammatory markers in cirrhotic and non-cirrhotic patients undergoing major abdominal surgery, and to explore the effects of cirrhosis and surgical intervention on central nervous system inflammation and cognitive dysfunction using a rat model. The investigators conducted a prospective study on cirrhotic and non-cirrhotic patients undergoing major abdominal surgery. Perioperative cognitive function was assessed using validated tools, and inflammatory markers were analyzed using Olink Target protein detection and bioinformatics approaches. Additionally, the investigators established a cirrhosis model using bile duct ligation (CBDL) in rats, followed by exploratory laparotomy to evaluate behavioral performance, BBB integrity and levels of inflammatory cytokines in serum and brain tissue.

This study looks at memory problems after surgery in people with liver disease. We want to know how often these problems happen and what might cause them. The main question it aims to answer is: 1. Do people with liver disease have more memory problems after stomach surgery than people without liver disease? If yes, how much more often? 2. Are changes in stomach bacteria and body chemicals related to these memory problems? Who can join: * Adults getting stomach surgery * Both people with and without liver disease What participants will do: * Take memory tests before and after surgery * Give stool (poop) and blood samples before and after surgery Why this matters: Memory problems after surgery can make recovery harder. If we find that stomach bacteria or body chemicals are involved, doctors might find new ways to prevent these problems in people with liver disease.

This study aims to evaluate the impact of widefield OCTA-guided selective photocoagulation on the progression of diabetic retinopathy (DR) by comparing the control of non-perfusion (NP) areas, DR grading, and management of other DR lesions. The study is designed as a parallel randomized controlled trial. From February 2025 to August 2026, 30 diabetic patients attending the Ophthalmology Department of Sichuan Provincial People's Hospital will be enrolled. Using a simple randomization method, one eye of each patient will be assigned to the intervention group, while the contralateral eye will serve as the control, resulting in 30 eyes in each group. The intervention group will undergo OCTA-guided selective photocoagulation, specifically using a grid pattern (3x3) of spot laser applied once to the NP area, extending one spot diameter beyond the NP boundary. Each session will last 10-20 minutes. The control group will receive no treatment. The study will compare changes in NP area, DR grading progression, and control of other DR lesions at 3, 6, 9, and 12 months between the two groups.

Lung cancer is with the highest incidence rate and mortality among people over 60 years old in China. Postoperative pulmonary complications (PPCs) is the most common complication after pneumonectomy, which has a significant impact on the short-term and long-term prognosis of patients, and is even the primary risk factor leading to early postoperative death. High fraction of inspired oxygen (FiO2) is an independent risk factor for PPCs, but it is difficult to achieve oxygenation while avoiding hyperxemia during one lung ventilation (OLV). We will randomly divide patients who plan to undergo thoracoscopic pulmonary resection into two groups. During OLV, titration will be used to determine the optimal FiO2 for titration group while FiO2 of 80% will be used for mechanical ventilation for control group. The incidence of postoperative PPCs, hypoxia/hyperxemia, severity level of postoperative PPC, postoperative 30 day PPC, increased hospitalization costs, and prolonged hospital stay will be observed in both groups of patients.We will evaluate the effectiveness and safety of titrating inhaled oxygen concentration in lung protection during OLV.
