The intraprostatic inflammatory infiltrate is characterized by Th1 CD4 T cells, and its molecular mechanism is not well defined. This study explored the mechanisms responsible for the alteration of Th1/Th17 differentiation of CD4 T cells in chronic non-bacterial prostatitis (CNP). CNP rats were induced by the administration of testosterone and 17β-estradiol.

The adverse effect of ambient PM exposure on very early pregnancy (VEP) remains controversial among epidemiological studies but is supported by toxicological evidence. We adopted a multicenter retrospective cohort of 141,040 cycles to evaluate the effect of PM exposure on the VEP using the fertilization and embryo transfer platform and high-resolution PM data in China. We first investigated the association between PM exposure 1 week before and 1 week after the embryo transfer date and VEP.

Objective: To evaluate the baseline albumin-bilirubin (ALBI) grade's role in advanced hepatocellular carcinoma (HCC) receiving transarterial chemoembolization (TACE) plus anti-angiogenesis therapies and PD-1 inhibitors (TACE+TP) versus anti-angiogenesis therapies and PD-1 inhibitors (TP).

Methods: This multicenter retrospective study enrolled advanced HCC undergoing TACE+TP or TP from January 2019 to June 2023 at three hospitals in China. The primary outcomes were time to progression of the ALBI grade and change in ALBI score between the initial baseline and the final assessment point available, the secondary outcomes consisted of overall survival (OS) as well as progression-free survival (PFS).

Background: Observational studies suggest the risk of primary ovarian insufficiency (POI) is increased in autoimmune disorders (AIDs), but it is unclear whether there is a causal relationship. Therefore, we aimed to investigate the bidirectional causality between 20 AIDs and POI using Mendelian randomization (MR) analysis.

Methods: A bidirectional two-sample MR investigation was designed by using publicly accessible summary-level data from genome-wide association studies (GWAS).

The cerebrospinal fluid (CSF) border accommodates diverse immune cells that permit peripheral cell immunosurveillance. However, the intricate interactions between CSF immune cells and infiltrating cancer cells remain poorly understood. Here we use fate mapping, longitudinal time-lapse imaging and multiomics technologies to investigate the precise origin, cellular crosstalk and molecular landscape of macrophages that contribute to leptomeningeal metastasis (LM) progression.

Background: Epithelial ovarian cancer (EOC) is a lethal form of gynecological malignancy. Some EOC patients experience relapse after standard primary debulking surgery (PDS) and adjuvant chemotherapy (ACT). Identifying molecular residual disease (MRD) by circulating tumor DNA (ctDNA) detection can timely signal the potential for relapse.

Bovine serum albumin (BSA) is one of the most abundant proteins in serum, and its high-throughput detection is still one of the current challenges. Nitrogen‑phosphorus co-doped carbon dots (CDs) were synthesized by a hydrothermal method. Adenosine monophosphate (AMP) was used as a precursor for the synthesis of CDs, providing the required carbon, nitrogen and phosphorus sources for the CDs.

Aims: Previous studies suggest potential associations between epilepsy, anti-epileptic drugs (AEDs), and levels of vitamin D and vitamin D-binding protein (VDBP). This study aims to investigate the causal relationships among these variables using Mendelian Randomization (MR) methods.

Methods: Using summary data from genome-wide association studies on serum 25-hydroxyvitamin D [25(OH)D] levels (N = 417,580), VDBP concentrations (N = 65,589), and various types of epilepsy (Ncases = 27,559), MR analyses were conducted to determine bidirectional causal relationships among these variables.

Puerariae Lobatae Radix, as a traditional Chinese medicine(TCM) with both medicinal and edible properties, possesses effects such as relieving muscle tension and fever, generating fluids and quenching thirst, and unblocking the meridians and collaterals. Modern fermentation technology, combined with microecology and modern bioengineering, can regulate the fermentation process and efficiently produce fermentation products. In recent years, modern fermentation technology has been widely applied in TCM, enhancing or altering efficacy, reducing toxicity, and expanding the scope of clinical applications.

Primary resection surgery is a conventional approach in breast cancer treatment, which plays a pivotal role in the prevention of recurrence and metastasis. In this study, an injectable hydrogel comprising chitosan (CS), β-glycerophosphate (β-GP), and dopamine (DA) with near-infrared (NIR) photothermal attributes was developed. The composite hydrogels integrate doxorubicin (DOX), termed DCGD, and can be used for chemotherapy, synergistic photothermal therapy, anti-bacterial and hemostasis.
