ObjectiveTo investigate the mechanism by which Wendantang regulates the silent information regulator 3 (SIRT3)/peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) pathway to influence energy metabolism and thereby prevent and treat myocardial ischemia (MI) in a rat model of hyperlipidemia (HL). MethodsThirty SD rats were randomly assigned into five groups: control, model, low-dose (3.702 g·kg-1·d-1) Wendantang, high-dose (7.404 g·kg-1·d-1) Wendantang, and positive control (trimetazidine, 0.006 g·kg-1·d-1), with six rats in each group. The control group was fed normally, while the other groups were fed with a high-fat diet for six weeks for the modeling of HL. Subsequently, the drug intervention groups were administrated with corresponding drugs by gavage, and the control and model groups received an equivalent volume of normal saline for 14 days. One hour after the last gavage, the other groups except the control group were injected intraperitoneally with posterior pituitary hormone (30 U·kg-1) to induce MI. Electrocardiography (ECG) was employed to detect changes in the electrocardiogram. Hematoxylin-eosin staining was performed to observe cardiac pathological changes. Enzyme-linked immunosorbent assay was employed to measure the serum levels of cardiac troponin I(cTnI), myoglobin (MYO), and creatine kinase-MB (CK-MB). Colorimetry was used to determine the levels of total cholesterol (TC) and triglycerides (TG) in the serum and ATP, malondialdehyde (MDA), and superoxide dismutase (SOD) in the myocardial tissue. Western blot was employed to determine the protein levels of SIRT3, PGC-1α, adenosine monophosphate-activated protein kinase (AMPK), and phosphorylated AMPK (p-AMPK) in the myocardial tissue. Real-time PCR was employed to measure the mRNA levels of SIRT3, PGC-1α, and AMPKα in the myocardial tissue. ResultsCompared with the control group, the model group showed significant J-point deviation and elevation in the ECG image, increased heart rate, disarrangement of myocardial fibers with unclear boundaries, elevated levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), declined levels of SOD and ATP (P<0.01), down-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05), and down-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05). Compared with the model group, the low-dose and high-dose Wendantang groups and the trimetazidine group showed inhibited J-point deviation and elevation in the ECG image, slowed heart rate, reduced inflammatory cell infiltration, alleviated disarrangement of myocardial fibers, declined levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), elevated level of SOD (P<0.01), up-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05, P<0.01) and up-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05, P<0.01). ConclusionWendantang can effectively intervene in HL-associated MI in rats by reducing oxidative stress in myocardial cells, alleviating lipid metabolism disorders, and improving myocardial energy metabolism via the SIRT3/PGC-1α signaling pathway.

3.Research progress on Helicobacter pylori CagA-induced gastric inflammation-cancer transformation
Journal of China Pharmaceutical University 2025;56(1):132-138
Helicobacter pylori (Hp) is currently classified as a class I carcinogen that can cause gastric cancer, research in recent years on how Hp infection causes the occurrence and progression of gastric cancer has attracted much attention. As the primary virulence factor of Hp, cytotoxicity-associated gene A (CagA) has been extensively studied and reported to function as a key excreted toxin for Hp to induce gastric infection, colonization and promote inflammatory-carcinogenic transformation of host cells. Patients infected with CagA-positive strains have a higher risk of developing tumors compared to those infected with CagA-negative strains. Based on previous studies, this article further elaborates on the import process, biological activity, and related molecular mechanisms of virulence protein CagA in the occurrence and development of gastric cancer induced by Hp infection.

Objective: To evaluate the feasibility and effectiveness of dual fluorescence laparoscopy in the localization of ureteral stricture and its blood supply,and to provide a new idea for the treatment of complex ureteral stenosis,thus helping doctors to improve the efficiency of ureteral reconstruction surgery. Methods: Our team developed a dual fluorescence laparoscopic system,which could simultaneously identify the ureter stricture by intra-ureteral injection of methylene blue (MB) and assess the blood supply of the ureteral stumps by intravenous injection of indocyanine green (ICG). Results: The clinical data of 3 patients who underwent lingual mucosa ureteroplasty using dual fluorescence laparoscopy in Zhongnan Hospital of Wuhan University were retrospectively analyzed.All operations were successful,without conversion to open surgery.The operation time was 144,132 and 163 minutes,respectively.The length of harvested lingual mucosa graft was 2.0,2.8 and 3.5 cm,respectively.No intraoperative or postoperative complications occurred.Eight weeks after operation,ureterography showed that the ureter was unobstructed. Conclusion: Dual fluorescence laparoscopy is safe and feasible in the repair of complex ureteral stricture with lingual mucosa graft,which provides a new idea for complex ureteral reconstruction.

Objective:
To investigate the characteristics and trend of stroke incidence in Yixing City, Jiangsu Province from 2016 to 2023, so as to provide the reference for formulating prevention and control strategies of stroke.
Methods:
Data of stroke case in Yixing City from 2016 to 2023 were collected from the National Health Information Platform of Yixing City, including sex, age, time of onset, and diagnostic subtypes. Crude incidence was standardized using the data from the 2010 Chinese National Population Census to analyze the characteristics of stroke incidence. The incidence trend of stroke was analyzed by average annual percent change (AAPC).
Results:
A total of 54 157 stroke cases were reported in Yixing City from 2016 to 2023, with a crude incidence of 629.52/100 000 and a standardized incidence of 299.50/100 000, showing an upward trend (AAPC=9.744% and 5.955%, both P<0.05). The crude and standardized incidence of stroke in males were significantly higher than those in females (695.30/100 000 vs. 565.79/100 000, 328.73/100 000 vs. 270.71/100 000, both P<0.05). Stroke incidence exhibited an age-dependent increase (P<0.05), peaking in the ≥60 years age group (1 820.43/100 000). The crude and standardized incidence of ischemic stroke (555.46/100 000 and 262.26/100 000) were significantly higher than those of hemorrhagic stroke (52.80/100 000 and 28.03/100 000, both P<0.05). From 2016 to 2023, the standardized incidences of stroke in males, females, the 0-<40 years age group, the 40-<60 years age group, the ≥60 years age group, and ischemic stroke all showed an upward trend (AAPC=6.692%, 4.925%, 5.607%, 5.777%, 5.698%, and 8.481%, respectively, all P<0.05). No significant temporal trend was observed for hemorrhagic stroke incidence (P>0.05).
Conclusions
The incidence of stroke among residents in Yixing City showed an upward trend from 2016 to 2023, with males and elderly individuals being high-risk populations. Ischemic stroke emerged as the predominant subtype, while a concerning trend of increasing stroke incidence among younger adults was observed.

Objective To utilize bioinformatic approaches to elucidate the correlation between secreted phosphoprotein 1(SPP1)and immune infiltration in various malignancies,elucidating the mechanism of gene function in cancer-immune cell interplay.Methods Cancer samples were derived from the Cancer Genome Atlas(TCGA)and Genotype-tissue Expression(GTEx)database,examining SPP1 expression difference between tumors and normal tissues using Gene Expression Profiling Interactive Analysis(GEPIA2),and its correlation with different immune cells in extracellular matrix via TIMER2 Database.SPP1's association with interacting molecules was scrutinized on the STRING website,followed by assessment of its distinct functional state across various cancers from Cancer Single-cell State Atlas Database(Cancer SEA).Results In 32 tumor types,SPP1 mRNA is significantly elevated in 23 types of cancers and correlates heavily with fibroblast,integrin family,and CD44.Furthermore,the SPP1 gene exhibits profound specificity in tumor functions such as vascular invasion,metastasis,DNA damage,and repair.Conclusion Specific expression of SPP1 in tumors signifies a significant correlation with tumor immune cells in the extracellular matrix,promoting tumor progression and invasion.This suggests that targeted monitoring of SPP1 could serve as a prospective cancer diagnostics/therapeutics biomarker.
