The combination of chemotherapy and photodynamic therapy holds immense potential for achieving synergistic anti-tumor efficacy. However, challenges such as poor stability and premature drug release prior to reaching tumor sites impede the widespread application of this synergistic therapeutic approach. In this study, a novel ATP-responsive NIR fluorescence nanosystem (CDZ) for imaging-guided chemotherapy and PDT has been developed.

In the pathogenesis of PD, inflammation hypothesis has been concerned. This study aims to investigate clinical indicators of peripheral inflammation in PD patients and to explore the diagnostic value of neutrophil-to-lymphocyte ratio (NLR), albumin-to-fibrinogen ratio (AFR), and lymphocyte-to-monocyte ratio (LMR) in assessing PD risk.

Known as a functional nutrient, betaine has potent antioxidant and anti-inflammatory properties in vivo. However, whether betaine can alleviate the abnormal behavior induced by chronic SI in mice remains unknown.

However, the specific mechanisms underlying cognitive impairment in different behavioral paradigms remain to be elucidated.
Methods: The study utilized two behavioral paradigms, novel location recognition (NLR) and novel object recognition (NOR), to investigate the brain regions involved in cognitive function.
Lung metastasis (LM) implies a very dismal event in patients with thyroid cancer. We aimed to construct a nomogram to predict LM for newly diagnosed stage IV thyroid cancer. A total of 1407 stage IV thyroid cancer patients were gathered from the surveillance, epidemiology, and end results (SEER) database.

In this study, a gridded emission inventory with a resolution of 3 km×3 km was established for six types of air pollutants from road and non-road mobile sources. The spatial and temporal distribution characteristics of pollutant emissions were analyzed, and the uncertainty of the inventory was analyzed using the Monte Carlo method.

This study aims to construct nomograms to predict overall survival (OS) and breast cancer-specific survival (BCSS) in breast cancer patients with lung metastasis, and to help clinicians develop appropriate treatment regimens for breast cancer lung metastasis (BCLM) individuals.
Methods: We gathered clinical data of 2,537 patients with BCLM between 2010 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database.
Aim: Chronic pancreatitis (CP) is a complex and intractable disease mainly manifested as chronic inflammation and fibrosis. Aspirin(acetylsalicylic acid, ASA) has been reported to be used in the treatment of acute pancreatitis (AP), but its effectiveness on CP is unclear. This study aimed to investigate the therapeutic effects of ASA in CP mice.

This study aimed to construct a high-quality model to predict overall survival (OS) and breast cancer-specific survival (BCSS) and help clinicians choose appropriate breast NEC treatments.
Patients And Methods: A total of 378 patients with breast NEC and 349,736 patients with breast invasive ductal carcinoma (IDC) were enrolled in the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2018.
Purpose: The aim of this study was to establish individualized nomograms to predict survival outcomes in older female patients with stage IV breast cancer who did or did not undergo local surgery, and to determine which patients could benefit from surgery.
Methods: A total of 3,129 female patients with stage IV breast cancer aged ≥70 years between 2010 and 2015 were included in the Surveillance, Epidemiology, and End Results program. Multivariate Cox regression analysis was used to identify risk factors for overall survival (OS) and breast cancer-specific survival (BCSS).
The activation of pancreatic stellate cells (PSCs) plays a critical role in the progression of pancreatic fibrosis. Nuclear factor-kappa B (NF-κB) is associated with chronic pancreatitis (CP). Previous evidence indicated that NF-κB in acinar cells played a double-edged role upon pancreatic injury, whereas NF-κB in inflammatory cells promoted the progression of CP.

Objective: To study the effects of Chai Qin Cheng Qi Decoction(CQCQD)(Traditional Chinese Medicine)on severe acute pancreatitis (SAP)complicated liver damage in rats.
Methods: Seventy-two SD rats were randomly divided into three groups(=24):Sham group, SAP group and CQCQD treatment group. SAP model was induced by retrograde injection with sodium taurocholate.
Activated pancreatic stellate cells (PSCs) play a crucial role in the progression of pancreatic fibrosis. Transforming growth factor-β (TGF-β) is one of the strongest stimulator inducing fibrosis. The mitogen-activated protein kinase (MAPK) proteins (including ERK, JNK and p38 MAPK) are known to contribute to PSC activation and pancreatic fibrosis.

The tolerance to adriamycin of cancer as a common and stubborn obstacle occurred during curing breast cancer patients needs to be overcome. In the present study, we explored whether inhibiting the glucose transporter 1 (GLUT1) could restore the activity of adriamycin in breast cancer cell line MCF-7 resistant to adriamycin and the possible underlying mechanisms. Adriamycin-resistant cell line MCF-7/ADR was selected stepwise from the parental MCF-7 cells and the level of GLUT1 was measured.

The mouse model was established by intravenous injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). SSTF (5 mg/kg) was administered to the mice before or after MPTP injection, and the effects of SSTF on the behavior of the mice and the dopaminergic neurons in the substantia nigra were assessed.
