Objective To explore the correlations of the severity degrees of coronary stenosis with cardiac function and exercise tolerance. Methods A total of 112 patients who underwent coronary angiography in Cardiology Department of Zhongshan Hospital, Fudan University between October 2024 and January 2025 were enrolled. According to the imaging results, the Gensini score was calculated, and the patients were divided into three groups based on the scores: mild group (＜20 points, n＝42), moderate group (20-40 points, n＝43), and severe group (＞40 points, n＝27). The left ventricular ejection fraction (LVEF), N-terminal pro-brain natriuretic peptide (NT-proBNP) level and its abnormal elevation ratio, 6-minute walk distance (6MWD), and grip strength were compared among the groups. The correlations between Gensini score and various indicators were analyzed using multivariate linear regression. And the multivariate binary logistic regression analysis was used to analyze the related factors of severe coronary stenosis. Results The 6MWD and LVEF values in the severe group were lower than those in the mild and moderate groups (P＜0.01), while the NT-proBNP level and its abnormal elevation ratio in the severe group were higher than those in the mild group (P＜0.05). The Gensini score was negatively correlated with 6MWD (β＝−0.965, P＜0.01), and positively correlated with NT-proBNP level and its abnormal elevation ratio (β＝0.015, P＜0.001; β＝0.003, P＝0.037). 6MWD and diabetes were independent related factors of severe coronary stenosis (OR＝0.956, P＜0.001; OR＝5.701, P＝0.038). Conclusions The cardiac function and exercise tolerance in patients with severe coronary stenosis decrease, 6MWD is helpful of recognizing severe coronary stenosis population.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

Objective To explore the effects of home-based exercise rehabilitation on cardiac structure, valvular function, and exercise capacity in patients with severe aortic stenosis (AS) after transcatheter aortic valve replacement (TAVR). Methods 49 patients with severe AS who underwent TAVR at Zhongshan Hospital, Fudan University, from January 2024 to February 2025 were enrolled. They were divided into an exercise group (n＝25) or a non-exercise group (n＝24) based on participating or not in home-based rehabilitation after TAVR. The exercise group received 12 weeks of home-based exercise training (aerobic exercise plus resistance training every week); the non-exercise group received routine care. Transthoracic echocardiography (TTE) was used to assess cardiac structural parameters before discharge (T0) and after 12 weeks of exercise (T1). Functional outcomes including the 6-minute walk test (6MWT), Duke Activity Status Index (DASI), and Short Physical Performance Battery (SPPB) were compared between the two groups. A linear mixed-effects model was used to analyze the effect of home-based rehabilitation on echocardiographic parameters. Patients were stratified by baseline 6MWT (＜240 m as low-function subgroup, ≥240 m as high-function subgroup) to compare exercise-related outcomes between subgroups. Results At T1, the exercise group had a longer 6MWT distance than the non-exercise group (P＝0.012). The linear mixed-effects model showed that after 12 weeks of exercise, the left ventricular end-diastolic diameter (LVEDD) decreased in the exercise group but slightly increased in the non-exercise group, with a significant difference in changes over time between the two groups (P_interaction＝0.030). The exercise group also showed greater improvement in effective orifice area index (P_interaction＝0.028) and effective orifice area (P_interaction＝0.042) than the non-exercise group. Subgroup analysis revealed that in the low-function subgroup, the exercise group showed greater improvement in the 6MWT (P_interaction＝0.035) and the effective orifice area index (P_interaction＝0.046) compared to the non-exercise group; in the high-function subgroup, the exercise group showed greater improvement only in LVEDD compared to the non-exercise group (P_interaction＝0.046). Conclusions Home-based exercise rehabilitation improves exercise capacity, optimizes left ventricular remodeling, and enhances valvular function in patients with severe AS after TAVR, with greater benefits observed in patients with lower baseline 6MWT.

Methods : Hepatic stellate cells were divided into blank group, model group(lipopolysaccharide 5 mg/L), and low, medium and high curcumol group(12.5, 25 and 50 mg/L); Thiazolyland(MTT) was used to detect the effects of curcumol on the viability of hepatic stellate cells; flow cytometry was used to detect the effects of curcumol on apoptosis of hepatic stellate cells; 5,5′,6,6′-Tetrachloro-1,1′,3,3′-tetraethylimidacarbocyanine iodide(JC-1) was used to detect the mitochondrial membrane potential; effects of curcumol on mitochondrial morphology and autophagosome were detected by transmission electron microscopy; effect of curcumol on mitochondrial localisation were detected by fluorescent probe; Immunoblotting assay was performed to detect the effects of curcumin on PTEN-induced putative kinase 1(PINK1), Parkinson's disease protein(Parkin), microtubule-associated protein light chain 3(LC3), autophagy-associated protein(Beclin1), mitochondrial inner membrane translocase 23(Timm23), mitochondrial outer membrane translocase 20(Tomm20), Bcl-2 associated X protein(Bax), B lymphocytoma-2(Bcl2), cleaved-cysteine protease 3(Caspase3), α-smooth muscle actin(ɑ-SMA), collagen type Ⅰ(Collagen Ⅰ), and collagen type Ⅲ(Collagen Ⅲ) protein expression. Results : Compared with the blank control group, cell proliferation rate, Caspase3, Bcl2, LC3Ⅱ, Beclin1, PINK1, Parkin, ɑ-SMA, CollagenⅠ, CollagenⅢ proteins significantly increased in the model group(P<0.01), co-localisation of mitochondria and lysosomes increased, and the number of mitochondrial autophagosome significantly increased(P<0.01), while Timm23 and Tomm20 proteins, mitochondrial membrane potential decreased significantly(P<0.01), apoptosis rate decreased, and Bax protein expression decreased. Compared with the model group, after curcumol intervention, cell proliferation rate, Bcl2, Timm23, Tomm20, α-SMA, CollagenⅠ and CollagenⅢ protein expression significantly decreased in the curcumol low-, medium-and high-concentration groups(P<0.01), and the mitochondrial membrane potential significantly decreased(P<0.01), whereas apoptosis rate, Caspase3, Bax, LC3Ⅱ, Beclin1, PINK1 and Parkin proteins significantly increased(P<0.05), the co-localisation of mitochondria and lysosomes increased, and the number of mitochondrial autophagosome significantly increased(P<0.01). Conclusion Curcumol exerts ameliorative effects on hepatic fibrosis by modulating mitochondrial hyperautophagy mediated by the PINK1/Parkin signaling pathway, and promoting hepatic stellate cell apoptosis.
