Alzheimer's disease (AD) is a common neurodegenerative disorder among the elderly, and BuChE has emerged as a potential therapeutic target. In this study, we reported the development of compound 8e, a selective reversible BuChE inhibitor (eqBuChE IC₅₀ = 0.049 μmol/L, huBuChE IC₅₀ = 0.066 μmol/L), identified through extensive virtual screening and lead optimization. Compound 8e demonstrated favorable blood-brain barrier permeability, good drug-likeness property and pronounced neuroprotective efficacy. Additionally, 8e exhibited significant therapeutic effects in zebrafish AD models and scopolamine-induced cognitive impairments in mice. Further, 8e significantly improved cognitive function in APP/PS1 transgenic mice. Proteomics analysis demonstrated that 8e markedly elevated the expression levels of very low-density lipoprotein receptor (VLDLR), offering valuable insights into its potential modulation of the Reelin-mediated signaling pathway. Thus, compound 8e emerges as a novel and potent BuChE inhibitor for the treatment of AD, with significant implications for further exploration into its mechanisms of action and therapeutic applications.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Purpose: This study compared the efficacy of heat insulation between 5% dextrose and 0.9% saline in radiofrequency ablation (RFA). Accordingly, temperature variations and maximum temperatures were assessed at identical distances and heat field distributions. Methods: Cubes of porcine liver tissue, measuring 10 mm across, were selected to precisely align the ablation boundary with the tissue boundary. An 18-gauge electrode with a 7-mm tip was inserted into each cube (10 per group) in a stainless-steel cup containing 40 mL of 5% dextrose or 0.9% saline. Fixed ablation was performed for 3 minutes using continuous mode at 30 W, simulating the typical thermal environment during thyroid RFA. Real-time temperature measurements were recorded by sensors positioned 0, 1, 3, and 5 mm from the cube’s edge. A comparative analysis was conducted to assess the maximum temperature, temperature variation, and duration of temperatures exceeding 42℃. Results: In both groups, the temperature curve declined with increasing distance from the edge of the ablated tissue. However, 0.9% saline exhibited higher maximum temperatures at 1, 3, and 5 mm compared to 5% dextrose (1 mm: 44.55°C±5.25°C vs. 34.68°C±3.07°C; 3 mm: 39.64°C±2.53°C vs. 29.22°C±2.21°C; 5 mm: 38.86°C±2.14°C vs. 28.74°C±2.51°C; all P<0.001). Considering a nerve injury threshold of 42°C, the 0.9% saline also displayed a greater proportion of samples reaching this temperature and a longer duration of temperatures exceeding it (P<0.05). Conclusion The heat insulation efficacy of 5% dextrose at 1-5 mm exceeds that of 0.9% saline at identical distances and in a common thermal environment during thyroid RFA.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.
