A near-infrared triggered multi-functional indocyanine green nanocomposite with NO gas release function inducing improved photothermal therapy.

The integration of photothermal and near-infrared (NIR) imaging capabilities of indocyanine green (ICG) small molecules has attracted considerable attention in tumor diagnosis and treatment. However, the abnormal upregulation of cellular heat shock proteins (HSPs) induced by photothermal therapy (PTT) enhances cellular heat resistance, thereby severely affecting the efficacy of PTT. In this study, to address the impact of HSPs on the efficacy of PTT while obtaining high-quality NIR fluorescence imaging in the NIR region, we designed a targeted peptide@ICG nanofluorescent probe encapsulated in liposomes.

A rare combined variation of left renal vasculature in a human cadaver: embryological basis and clinical significance.

Classically, a single renal artery supplies, and a single renal vein drains each kidney. The morphology and variations in the renal vascular structures are of great importance when performing any type of renal surgery. The present case describes a rare combination of renal vasculature variation in a formalin-fixed, Chinese male cadaver.

NIR-II fluorescence microscopic bioimaging for intrahepatic angiography and the early detection of microlesions.

Hepatic alveolar echinococcosis (HAE) is caused by the metacestode of , which shows characteristics of malignant tumors with high mortality. However, traditional diagnostic imaging methods are still not sufficient for the recognition of HAE microlesions in the early stages. Near-infrared-II (900-1700 nm, NIR-II) fluorescence microscopic imaging (NIR-II-FMI) has shown great potential for biomedical detection.

Bradykinin B1 receptor antagonist protects against cold stress-induced erectile dysfunction in rats.

Background: Erectile dysfunction (ED) demonstrates seasonal variation with higher rates in winter, and we hypothesize that endothelial damage in erectile tissue caused by bradykinin receptor B1 (B1R) might be detrimental to this change.

Aim: To find out direct correlations between cold stress and ED, through which to further investigate the functional roles of B1R in erectile tissue and to elucidate the therapeutic roles of the B1R antagonist in a cold stress-induced ED rat model.

Methods: Cold stress rat models are established through long-term intermittent exposure to low temperature.

Influence of humanized nursing on patients with intracranial aneurysm subarachnoid hemorrhage undergoing interventional embolization.

Objective: To investigate the effect of nursing intervention on patients with intracranial aneurysm subarachnoid hemorrhage who underwent interventional embolization.

Methods: According to the random number table method, 80 patients with subarachnoid hemorrhage caused by intracranial aneurysm who received interventional embolization in our hospital from September 2018 to May 2021 were randomly divided into a control group of 40 cases and an observation group of 40 cases. 40 cases, the two groups were implemented routine nursing and humanized nursing.

Effects of phytoestrogens combined with cold stress on sperm parameters and testicular proteomics in rats.

Phytoestrogens and cold negatively influence male fertility. However, the combined effects of these two factors on male reproduction remain unknown. Herein, we studied the changes of sperm parameters and identify potential biomarkers involved in testis of rats, which were intervened by phytoestrogens combined with cold stress.

Variant formation and branching pattern of superficial palmar arch in a human cadaver: a case report.

Superficial palmar arch (SPA) is a dominant vascular structure in the palmar region that provides a major blood supply to fingers. Present case describes a rare formation and branching pattern of SPA in a formalin fixed cadaveric left hand. In this case, SPA was formed by the anastomoses between radial artery (RA) and the superficial brachioulnar artery (SBUA), which is defined as an ulnar artery with a high origin in the arm.

The potential biological effects of quercetin based on pharmacokinetics and multi-targeted mechanism .

Quercetin is a plant-derived polyphenol flavonoid that has been proven to be effective for many diseases. However, the mechanism and metabolism of quercetin remains to be clarified. It achieves a wide range of biological effects through various metabolites, gut microbiota and its metabolites, systemic mediators produced by inflammation and oxidation, as well as by multiple mechanisms.

iTRAQ-based identification of differentially expressed proteins in ED rat model induced by cold stress combined with environmental oestrogen.

We aim to identify serum biomarkers and key proteins of erectile dysfunction (ED) induced by cold stress combined with environmental oestrogen through iTRAQ combined with LC-MS/MS. ED rat model was established by using oestrogen-like feed and cold stimulation. Differentially expressed proteins in serum were screened and analysed with iTRAQ combined with LC-MS/MS and IPA bioanalysis platform.

[Regulatory effect of the lipid metabolic pathways of TMAO, FMO3 and FXR on compound stress-induced ED in rats and mechanisms of Yimusake intervention].

Objective: To study of the regulatory effects of the lipid metabolic pathways of trimethylamine-N-oxide (TMAO), flavin-containingmonooxidase 3 (FMO3) and farnesoid X receptor (FXR) on compound stress-induced ED (CSED) rats and the mechanisms of Yimusake Tablets (YMSK) intervention.

Methods: Based on the results of metabonomics analysis, we determined the concentration of TMAO in the serum of the rats in the normal control (n = 30), the CSED model control (n = 30) and the YMSK intervention group (intragastrical administration of YMSK at 250 mg/kg once daily for 2－3 weeks after modeling, n = 30) by nuclear magnetic resonance (NMR) spectroscopy test. We also detected the expressions of the FMO3, FXR1 and FXR2 proteins in the liver tissue of the three groups of rats by Western blot.

Neuroplastin 65 modulates anxiety- and depression-like behavior likely through adult hippocampal neurogenesis and central 5-HT activity.

Neuroplastin 65 (Np65) is a brain-specific cell adhesion molecule that is highly expressed in the hippocampus, amygdala, and cortex, regions of the brain that are associated with memory and emotions. However, the role of Np65 in regulation of emotional behavior is still unclear. In the present study, we show that Np65 knock-out (Np65 KO) mice display enhanced anxiety-like behavior, a reduction in some aspects of depressive-like behaviors, and increased sociability and memory.

A rare variation of the hemiazygos vein draining into the persistent left superior vena cava.

During an educational dissection of a 72-year-old Chinese male cadaver, the hemiazygos vein (HAV) coursing the left side that drains into the persistent left superior vena cava was observed. The HAV was formed at the junction of the 9th to 11th right posterior intercostal veins, right subcostal vein, 5th to 11th left posterior intercostal veins, and left subcostal vein; it then ascended posteriorly to the thoracic aorta. After collecting the accessory hemiazygos vein, it crossed over the aorta and the pedicle of the left lung via the hemiazygos arch, then converged with a communicative branch (vein of Marshall) that emerged from the left brachiocephalic vein to form the persistent left superior vena cava and entered the pericardium at the level of the sixth thoracic vertebra.

Neuroplastin 65 mediates cognitive functions via excitatory/inhibitory synapse imbalance and ERK signal pathway.

Neuroplastin 65 (NP65) is a brain-specific glycoprotein component of synaptic membrane, which is predominantly located in the forebrain such as the cortex, amygdala and striatum and hippocampus. Previous studies have shown that NP65 is implicated in synaptic plasticity, so it was hypothesized to play roles in cognitive functions. To test this hypothesis, we generated NP65 knock-out (KO) mice and found that the null mice exhibited enhanced hippocampus-dependent learning and memory as manifested by Morris water maze test and step-through passive avoidance test, but showed anxiety-like behaviors as manifested by open field test and light/dark exploration test.
