In the past, a large number of animal studies have suggested that anesthesia exposure has potential neurotoxic effects, resulting in persistent cognitive and behavioral deficits. At present, there is still a lack of sufficient clinical research evidence to prove whether anesthesia exposure has long-term effects on neurodevelopment. The existing clinical research data suggests that a single short-time anesthesia exposure in young children does not affect long-term neurodevelopmental outcomes. Early onset scoliosis, including congenital scoliosis, is a type of scoliosis deformity that occurs before the age of 10. Posterior scoliosis correction surgery is one of the common treatment. There is currently no research indicating the impact of early single or multiple long-duration anesthesia exposure on the neurological development of children with congenital scoliosis. The aim of this study is to determine the long-term effect of general anesthesia exposure on neurocognitive function and behavior in children with congenital scoliosis, in order to provide reference for related clinical work.

The study aim is to explore the correlation between exercise and hyperuricemia, find out the metabolic rule of uric acid after exercise, and provide scientific evidence and clinical guidance for how to exercise scientifically and reasonably in patients with hyperuricemia. This trial is a multicenter, prospective, randomized controlled clinical trial with 100 participants. Inclusion criteria: 1. Patients with hyperuricemia (fasting uric acid > 420μmol/L twice on different days); 2. Men aged between 18 and 35; 3. Able to complete baseline fitness test (3000m run time less than 14 minutes); 4. Fully informed consent, signed informed consent exclusion criteria: 1. Patients with heart, liver and kidney insufficiency. 2. Subjects suffering from severe or uncontrollable organic diseases may interfere with study parameters such as hypertension, hyperlipidemia, hyperglycemia, tumor, cardiovascular, lung and digestive diseases. 3. Patients with secondary hyperuricemia caused by other diseases. 4. Take any drugs that may cause uric acid changes in the past 4 weeks. 5. Those who have related motor function or other factors are easy to cause discomfort after exercise. 6. Those who have mental illness or communicate do not cooperate during the test. A total of 100 participants participated in the study（Group A n = 50 ; Group B n = 50 ）. The subjects are divided into two groups, designated as A and B. Following the completion of the grouping, all subjects complete the initial 3000 m run. The second 3000 m run is performed on the seventh day following the initial run. The interval between the third run and the second run in Group A is 24 hours, while the interval in Group B is 48 hours. During the 48-hour observation period after each exercise, the changes of uric acid after exercise were explored. To provide scientific evidence and clinical guidance for patients with hyperuricemia how to exercise scientifically and rationally. Patients must meet all inclusion and exclusion criteria to be eligible to participate in the study. After determining patients' eligibility for the study, the researcher should fully explain the nature, purpose, risks and benefits of the study to the subjects before the study, and assure the patients that they have the right to withdraw at any time after agreeing to participate in the study, and the subjects should sign a written informed consent after fully considering and agreeing to participate in the study. The process of obtaining informed consent should be correctly recorded in all case report forms in this study. Baseline data such as blood uric acid, blood biochemistry, blood routine, urine routine, uric acid, and demographic characteristics were collected after the patients were enrolled. The patients were randomly divided into two groups: Group A and Group B. Within 48 hours after each 3000m exercise, the subjects' blood uric acid was detected after exercise 1 hour, 2 hours, 3 hours, 12 hours, 24 hours, 36 hours, 48 hours. From January 2024 to February 2024, we plan to draft clinical study protocols, investigator manuals, case reports, informed consent forms and other documents, and submit them to the Ethics Committee of the research sponsor for review and approval; February 2024 - March 2024: Complete the training of all researchers and officially start the research; March 2024 - August 2024: Participants were enrolled for the experiment; August 2024 - November 2024: collate and collect data, conduct statistical analysis, and confirm research results
The purpose of this study is to explore the clinical effect of reducing uric acid by drinking water, and provide scientific evidence and clinical guidance for reducing uric acid by drinking water. The study design was a multicenter, prospective, randomized controlled clinical trial with a total of 88 participants (Group A n=44; Group B n=44). 1. Inclusion criteria: patients with hyperuricemia (fasting uric acid between 420-540μmol/L twice on different days and no drug treatment); Aged 18-65 years; Less than 1500mL of daily water intake recommended by the minimum dietary guidelines (assessed by dietary review combined with water diaries); Fully informed consent. Sign informed consent. 2. Exclusion criteria: Patients with heart, liver and kidney insufficiency; Patients with severe or uncontrollable organic diseases that may interfere with the study parameters (such as tumors, cardiovascular, pulmonary and digestive diseases, hypertension, hyperlipidemia, hyperglycemia, thyroid diseases) or psychiatric disorders that affect eating behavior (such as primary polydipsia, bulimia nervosa, Psychiatric disorders, etc.); Patients with secondary hyperuricemia caused by other diseases; Patients who have taken any drug that causes changes in uric acid within five half-lives of the drug; Receiving treatment that can change the assessment of hydration status in the study (taking diuretics, glucocorticoids, or treatments that interfere with metabolism); Those who have gastrointestinal discomfort or a history of gastrointestinal surgery after drinking water, and other patients who are not suitable to drink too much water. A total of 88 subjects were included according to the exclusion criteria. The subjects were divided into two groups: Group A adequate drinking water intervention group (drinking an additional 1650mL of water per day (3 bottles of 550mL bottled water) on the basis of the original drinking water volume); Group B constant drinking water observation group (maintaining the original drinking water volume). During the 2-week observation period, the effects of sufficient drinking water on blood uric acid, urine osmotic pressure and other indicators were evaluated, and the effectiveness of sufficient drinking water in reducing blood uric acid was determined, and the applicable population was explored. Observation items and detection time: 1. During the screening period, the following data were collected: age, nationality, place of residence, education, occupation, height, weight, waist circumference, disease history, drug use history, drinking, smoking, normal water intake, urine volume, urine color and uric acid value. 2. Pre-test data: drinking water, urination, diet, psychological investigation, blood uric acid, blood biochemistry, routine blood routine, urine routine, uric acid, urine osmotic pressure, systolic blood pressure, diastolic blood pressure, heart rate, frequency of gout attack, whether to take uric-lowering drugs, whether to take other drugs that affect uric acid. 3. After the test: Fasting blood uric acid was monitored on the 2nd, 4th, 6th, 8th, 10th and 14th day respectively; Urge patients to record water diary and urination diary every day. At the end of the experiment, blood uric acid, blood biochemistry, blood routine, urine routine, urine uric acid, urine osmotic pressure, systolic blood pressure, diastolic blood pressure and heart rate were tested again. Safety assessment indicators: edema, gastrointestinal discomfort, electrolytes, blood pressure, heart rate.

This study explores the effectiveness of combining electroacupuncture with olanzapine-containing four-drug antiemetic therapy to mitigate chemotherapy-induced nausea and vomiting (CINV) in patients with breast cancer. The research aims to assess the adjunctive benefits of electroacupuncture in enhancing the antiemetic effects of conventional medication, particularly in the context of highly emetogenic chemotherapy regimens. By investigating the synergistic potential of these modalities, the study seeks to provide insights into optimizing supportive care strategies for patients with breast cancer undergoing intensive chemotherapy treatment.
