A dose-escalation study of HP501, a highly selective URAT1 inhibitor, in male Chinese patients with hyperuricemia.

HP501 is a highly selective renal urate transporter 1 (URAT1) inhibitor used for treating hyperuricemia. This study aimed to evaluate the tolerability, pharmacokinetics, and pharmacodynamics of HP501 in male Chinese patients. Patients with hyperuricemia were sequentially assigned to receive oral doses of HP501 (30, 50, 60, 90, and 120 mg) as a single dose on Day 1 and as once-daily doses from Days 4 to 13.

Prognostic models for predicting overall and cancer-specific survival of patients with initially diagnosed metastatic cervical squamous cell carcinoma: A study based on SEER database.

Cervical squamous cell carcinoma (CSCC) is the most common histological type of cervical cancer (CC). And mCSCC is the end stage of CSCC. The aim of this study was to develop prognostic nomograms that provide better predictions for overall survival (OS) and cancer-specific survival (CSS) in mCSCC patients.

A Phase I Study to Evaluate the Pharmacokinetic Drug‒Drug Interaction of HP501, Febuxostat, and Colchicine in Male Chinese Patients with Hyperuricemia.

Background And Objective: HP501 is a highly selective renal urate transporter 1 (URAT1) inhibitor that is being developed for the treatment of hyperuricemia and gout. The primary aim of the present study was to study the pharmacokinetic drug‒drug interactions (DDIs) of HP501, febuxostat, and colchicine in hyperuricemic patients.

Methods: Hyperuricemic patients were randomly divided into group A, receiving HP501 40 mg once daily on days 1 and 4-10, and group B, receiving febuxostat 40 mg once daily on day 1 and HP501 40 mg plus febuxostat 40 mg on days 4-10.

Novel therapies for malignant pleural effusion: Anti‑angiogenic therapy and immunotherapy (Review).

Patients with a variety of malignancies can develop malignant pleural effusion (MPE). MPE can cause significant symptoms and result in a marked decrease in quality of life and a poor prognosis. MPE is primarily considered as an immune and vascular manifestation of pleural metastases.

Development of immunotherapy for brain metastasis (Review).

Brain metastasis (BM) is associated with a poor prognosis, with the typical overall survival rate ranging from weeks to months in the absence of treatment. Although the concept of immune privilege in the central nervous system has eroded over time, the advent of immunotherapy has opened a new set of potential therapeutic options for patients with BM. Recently, immunotherapy has been demonstrated to confer survival advantages to patients with multiple malignancies commonly associated with BMs.

Glycyrrhetinic Acid-Modified Norcantharidin Nanoparticles for Active Targeted Therapy of Hepatocellular Carcinoma.

Norcantharidin (NCTD), the demethylated analogue of cantharidin, has been confirmed to have a good anti-tumor effect against hepatocellular carcinoma (HCC). However, its use is limited by its poor water solubility and low tumortargeting efficacy. In the present study, an active-targeted drug delivery nanoplatform was designed to deliver NCTD using a glycyrrhetinic acid (GA)-decorated copolymer (mPEG-PCL-PEI-GA, MPG).

Honokiol-loaded polymeric nanoparticles: an active targeting drug delivery system for the treatment of nasopharyngeal carcinoma.

The purpose of this study was to develop a novel drug delivery system for a sustained and targeted delivery of honokiol (HK) to the nasopharyngeal carcinoma (NPC) HNE-1 cell lines, since the folate receptor (FR) is over-expressed on their surface. Emulsion solvent evaporation was used to develop the active targeting nanoparticles-loaded HK (ATNH) using copolymerpoly (ɛ-caprolactone)-poly (ethyleneglycol)-poly (ɛ-caprolactone) (PCEC), which was modified with folate (FA) by introducing Polythylenimine (PEI). ATNH characterization, including particle size distribution, morphology, drug loading, encapsulation efficiency and drug release, was performed.

Periostin Promotes Neural Stem Cell Proliferation and Differentiation following Hypoxic-Ischemic Injury.

Neural stem cell (NSC) proliferation and differentiation are required to replace neurons damaged or lost after hypoxic-ischemic events and recover brain function. Periostin (POSTN), a novel matricellular protein, plays pivotal roles in the survival, migration, and regeneration of various cell types, but its function in NSCs of neonatal rodent brain is still unknown. The purpose of this study was to investigate the role of POSTN in NSCs following hypoxia-ischemia (HI).

Neuroprotective effects of oligodendrocyte progenitor cell transplantation in premature rat brain following hypoxic-ischemic injury.

Periventricular leukomalacia (PVL) is a common ischemic brain injury in premature infants for which there is no effective treatment. The objective of this study was to determine whether transplanted mouse oligodendrocyte progenitor cells (OPCs) have neuroprotective effects in a rat model of PVL. Hypoxia-ischemia (HI) was induced in 3-day-old rat pups by left carotid artery ligation, followed by exposure to 6% oxygen for 2.

Clinical value of spectral CT in diagnosis of negative gallstones and common bile duct stones.

Objective: To investigate the clinical value of spectral CT in diagnosis of negative gallstones and common bile duct stones primarily.

Methods: All patients diagnosed with negative biliary stones were analyzed and examined by spectral CT scanner retrospectively. Based on acquired raw imaging data, image series were reconstructed as described below: the optimal contrast-to-noise ratio monochromatic energy images, calcium- and fat- based material decomposition images and spectral curve images.

Cerebral hypoxia-ischemia increases toll-like receptor 2 and 4 expression in the hippocampus of neonatal rats.

Aim Of The Study: Recent reports provide evidence that Toll-like receptors (TLRs) play a crucial role in cerebral ischemic injuries and neuronal cell death. The precise role of TLRs in mediating neuronal damage remains to be fully elucidated. In this study, we investigated the expression of TLR2 and TLR4 in the hippocampus of the neonatal rats.

Short-term effects of hypothermia on axonal injury, preoligodendrocyte accumulation and oligodendrocyte myelination after hypoxia-ischemia in the hippocampus of immature rat brain.

Hypothermia is known to improve neurological recovery of animals and humans exposed to hypoxic-ischemic (HI) injury. However, the underlying mechanisms of the neuroprotective effects of hypothermia are only partially understood, including decreased excitotoxicity and apoptosis, and suppressed inflammation. There are few studies about the hypothermic effects on axonal injury and oligodendrocyte (OL) lineage degeneration, which are important components of neonatal brain injuries that cause cognitive disability.
