Purpose: Tangzhiqing formula (TZQ) is a traditional Chinese medicine prescribed to treat lipid metabolism disorders, atherosclerosis, diabetes and diabetic cardiomyopathy. However, some challenges and hurdles remain. TZQ showed promising results in treating diabetes and hyperlipidaemia. However, its effect on and mechanism of action in hyperlipidaemia complicated with myocardial ischaemia (HL-MI) remain unknown.
Methods: In this study, a network pharmacology-based strategy integrating target prediction was adopted to predict the targets of TZQ relevant to the treatment of HL-MI and to further explore the involved pharmacological mechanisms.
Results: A total of 104 potential therapeutic targets were obtained, including MMP9, Bcl-2, and Bax, which may be related to the apoptosis and PI3K/AKT signalling pathways. Then, we confirmed these potential targets and pathways with animal experimentation. TZQ reduced lipid levels, increased the expression levels of Bcl-2, decreased Bax, caspase-3 and caspase-9 expression levels, and activated the PI3K/AKT signalling pathway.
Conclusion: In conclusion, this study provides new insights into the protective mechanisms of TZQ against HL-MI through network pharmacology and pharmacological approaches.

A superior tool for predicting sepsis in SAH patients: The nomogram outperforms SOFA score.
PLoS One
January 2025
Jinan University, Guangzhou, China.
Objective: This study aimed to develop and validate a nomogram to predict the risk of sepsis in non-traumatic subarachnoid hemorrhage (SAH) patients using data from the MIMIC-IV database.
Methods: A total of 803 SAH patients meeting the inclusion criteria were randomly divided into a training set (563 cases) and a validation set (240 cases). Independent prognostic factors were identified through forward stepwise logistic regression, and a nomogram was created based on these factors.

Post-stroke early activation of neutrophils contributes to intensive neuroinflammation and worsens disease outcomes. Other pre-existing patient conditions can modify the extent of their activation during disease, especially hypercholesterolemia. However, whether and how increased circulating cholesterol amounts can change neutrophil activation responses very early after stroke has not been studied.

Objectives: Limited studies reported the correlation between Sjögren's syndrome (SS) and vitiligo. This study explores the association between SS and the risk of developing vitiligo and assesses comorbidity profiles and medication impacts.
Methods: We conducted a retrospective, population-based analysis using data from Taiwan's National Health Insurance Research Database, spanning 2008 to 2019.
Triglyceride lowering in patients with different severities of hypertriglyceridaemia-associated acute pancreatitis: secondary analysis of a multicentre, prospective cohort study.
BMJ Open Gastroenterol
January 2025
Department of Critical Care Medicine, Longyan First Affiliated Hospital of Fujian Medical University, Longyan, Fujian, China
Objective: It is controversial whether rapid lowering of triglyceride (TG) levels is associated with clinical benefits in patients with hypertriglyceridaemia-associated acute pancreatitis (HTG-AP). In particular, patients with different severity of disease may respond differently to TG-lowering therapy. In this study, we aimed to explore the association between rapid decline in serum TG levels and organ failure in patients with different severities of HTG-AP.
