ABSTRACT

This study aimed to explore the moderating role of socioeconomic status (SES) in the association between multimorbidity and health-related quality of life (HRQOL) among cancer patients in Anhui China. A total of 560 cancer patients were recruited for the cross-section study. Socio-demographic and clinical characteristics were analyzed using descriptive statistics. Tobit regression analysis was employed to investigate the relationship between multimorbidity and HRQOL as well as to assess the moderating effect of SES. The research findings indicated that 76.61% of cancer patients experienced multimorbidity, with psychological multimorbidity being the most prevalent (45.54%), followed by physical-psychological multimorbidity (20.89%). Moreover, physical-psychological multimorbidity had the most substantial adverse effect on HRQOL (P < .001). The presence of multimorbidity was correlated with a significant decline in HRQOL, with a 17.5% (P < .001) decrease in HRQOL for each additional multimorbidity. Additionally, SES played a significant role in moderating the impact of multimorbidity on HRQOL in cancer patients. (Marginal effect = -0.022, P < .01). The high SES group exhibited a higher overall HRQOL than the low SES group (Marginal effect = 0.068, P < .001). And with the increase of multimorbidity, HRQOL in the higher SES showed a more pronounced downward trend, compared with the lower SES (ß = -.270 vs ß = -.201, P < .001). Our findings underscore the importance of preventing and managing multimorbidity in cancer patients, particularly those with low SES. Furthermore, it is essential to consider the impact of the rapid decline in HRQOL as the number of multimorbidity increases in individuals with higher SES. It is imperative to explore interdisciplinary and continuous collaborative management models.

ABSTRACT

OBJECTIVE: To explore the effects of comprehensive nursing intervention on in vitro fertilization (IVF) and pregnancy outcomes in patients with polycystic ovary syndrome (PCOS). METHOD: A total of 130 patients with PCOS admitted to our hospital from April 2021 to March 2023 were selected as the research subjects. They were evenly divided according to a random number table method. The control group received routine care for the patients, while the study group received comprehensive care for the patients. The IVF, pregnancy outcomes, negative emotional changes, serum and follicular fluid (FF) amyloid-related protein and C-reactive protein (CRP) levels of the 2 groups of patients were compared. RESULT: The data on IVF rate and pregnancy rate in the study group were significantly better than those in the control group (P < .05). The SAS and SDS scores of the study group patients after intervention were significantly lower than those of the control group (P < .05). After intervention, the levels of serum and FF amyloid associated protein and CRP in the study group were significantly lower than those in the control group (P < .05). CONCLUSION: Patients with PCOS who receive comprehensive care can increase their probability of IVF, improve their pregnancy outcomes, and have a positive significance in reducing negative emotions.

ABSTRACT

T cells play an important role in tumor immune surveillance. CD147 is a member of immunoglobulin superfamily present on the surface of many tumor cells and mediates malignant cell behaviors. Cyclophilin A (CypA) is an intracellular protein promoting inflammation when released from cells. CypA is a natural ligand for CD147. In this study, CD147 specific short hairpin RNAs (shRNA) were transfected into murine hepatocellular carcinoma Hepa1-6 cells to assess the effects of CD147 on hepatoma cells escaping from immune surveillance of T cells. We found extracellular CypA stimulated cell proliferation through CD147 by activating ERK1/2 signaling pathway. Downregulation of CD147 expression on Hepa1-6 cells significantly suppressed tumor progression in vivo, and decreased cell viability when co-cultured with T cells in vitro. Importantly, knockdown of CD147 on Hepa1-6 cells resulted in significantly increased T cells chemotaxis induced by CypA both in vivo and in vitro. These findings provide novel mechanisms how tumor cells escaping from immune surveillance of T cells. We provide a potential therapy for hepatocellular carcinoma by targeting CD147 or CD147-CypA interactions.

ABSTRACT

The impacts of rutin and baicalin on the interaction of curcumin (CU) with human serum albumin (HSA) were investigated by fluorescence and circular dichroism (CD) spectroscopies under imitated physiological conditions. The results showed that the fluorescence quenching of HSA by CU was a simultaneous static and dynamic quenching process, irrespective of the presence or absence of flavonoids. The binding constants between CU and HSA in the absence and presence of rutin and baicalin were 2.268×10(5)M(-1), 3.062×10(5)M(-1), and 3.271×10(5)M(-1), indicating that the binding affinity was increased in the case of two flavonoids. Furthermore, the binding distance determined according to Förster's theory was decreased in the presence of flavonoids. Combined with the fact that flavonoids and CU have the same binding site (site I), it can be concluded that they may simultaneously bind in different regions in site I, and formed a ternary complex of flavonoid-HSA-CU. Meanwhile, the results of fluorescence quenching, CD and three-dimensional fluorescence spectra revealed that flavonoids further strengthened the microenvironmental and conformational changes of HSA induced by CU binding. Therefore, it is possible to develop a novel complex involving CU, flavonoid and HSA for CU delivery. The work may provide some valuable information in terms of improving the poor bioavailabiliy of CU.

ABSTRACT

Wogonin is considered to be an inhibitor of myeloid cell leukemia 1 and B-cell lymphoma 2, and a potential antitumor drug due to its ability to induce apoptosis in certain cancer cells; however, few previous studies have reported on wogonin-induced autophagy. The aim of the present study was to investigate the influence of wogonin on autophagy in human pancreatic cancer cells (HPCCs), elucidate its mechanism, and identify strategies to increase its effectiveness as an anti-cancer treatment. HPCCs were treated with wogonin and autophagy was detected in the cells. The mechanism of wogonin-related autophagy was investigated, and the antioxidant N-acetyl-L-cysteine (NAC) was used to assess the role of reactive oxygen species (ROS) in wogonin-related autophagy. The results demonstrated that wogonin may induce autophagy by activating the Beclin-1/phosphatidylinositol-3-kinase and ROS pathways in HPCCs, and may enhance ROS generation, followed by the activation of the AKT/ULK1/4E-BP1/CYLD pathway and inhibition of the mammalian target of rapamycin signaling pathway. The incubation of HPCCs with wogonin and the antioxidant NAC, revealed that the effects of wogonin-enhanced ROS generation on autophagy-related molecules were inhibited, contributing to the inhibition of autophagy and increasing the cell death ratio through apoptosis activation in HPCCs. These studies suggest that autophagy activation, via the ROS pathway, by the antitumor drug wogonin in HPCCs may partially reduce the antitumor effects of the drug, and that the antioxidant NAC may enhance the antitumor effectiveness of wogonin via the inhibition of ROS-enhanced autophagy and the subsequent promotion of apoptosis. Therefore, the present research suggests that wogonin combined with NAC may be a novel combination therapy for clinical pancreatic cancer therapy trials.

ABSTRACT

BACKGROUND: A satisfied glaucoma model is absent now. The aim of this study was to evaluate the effect of a combination of intracameral injection of silicone oil and electrocoagulation of corneal limbal vessels and episcleral veins in the rats to establish glaucoma model. METHODS: Operation was performed in each of the left eyes of 90 adult male rats. Right eyes were used as controls. Measurement of intraocular pressure (IOP) was performed with an applanation tonometer (Tono-Pen). Retinal ganglion cells (RGCs) were retrogradely labeled by applying FluoroGold onto the bilateral superior colliculus. RESULTS: During the follow-up (24 weeks), the IOP of the study eyes was significantly higher (P < 0.05) than the control eyes (at final examination, IOP of control eyes was (13.4 ± 1.0) mmHg and IOP of study eyes was (16.1 ± 1.8) mmHg). Correspondingly, at 24 weeks after operation, the RGCs density of the study eyes (2286.11 ± 290.45/mm(2)) was significantly lower than the control eyes (2626.46 ± 164.85/mm(2), P < 0.01). In the operated eyes, histological examination showed excavation of optic disc and increased neuroglial cells in the optic nerve, reduced thickness of retina and diminution of retinal ganglion cells, and atrophy of ciliary body and iris. Notably, the anterior chamber angle of the operated eye remained open. CONCLUSIONS: A combination of intracameral injection of silicone oil and electrocoagulation of corneal limbal vessels and episcleral veins may establish a reliable glaucoma model for further research.
