PYCR1 expresses in cancer-associated fibroblasts and accelerates the progression of C6 glioblastoma.

Background: Cancer-associated fibroblasts (CAFs) play important roles in tumor microenvironments. Pyrroline-5-carboxylate reductase 1 (PYCR1) is a potential cancer therapy target. This study aimed to explore the expression of PYCR1 in glioma-associated CAFs and analyze the effects of PYCR1 expression in CAFs on the proliferation of C6 glioma.

Characteristics of glioblastomas and immune microenvironment in a Chinese family with Lynch syndrome and concurrent porokeratosis.

Background: Lynch syndrome (LS)-associated glioblastoma (GBM) is rare in clinical practice, and simultaneous occurrence with cutaneous porokeratosis is even rarer. In this study, we analyzed the clinicopathological and genetic characteristics of LS-associated GBMs and concurrent porokeratosis, as well as evaluated the tumor immune microenvironment (TIME) of LS-associated GBMs.

Methods: Immunohistochemical staining was used to confirm the histopathological diagnosis, assess MMR and PD-1/PD-L1 status, and identify immune cell subsets.

Potential epidural anesthesia risk of spinal dural arteriovenous fistula diagnosed and evaluated by indocyanine green fluorescence.

A patient was admitted to our hospital and scheduled to receive left knee arthroplasty and right knee arthroscopic debridement under epidural anesthesia. After anesthesia and surgery, the patient developed below T12 sensory perception lost, urinary retention and fecal incontinence. Magnetic resonance examination was conducted.

A Rare Case of Craniocervical Penetrating Injury by a Steel Bar.

Rationale: Non-missile penetrating injuries caused by foreign bodies, such as knives or sharp wood, are infrequent. We report a 49-year-old male suffering from severe craniocervical penetrating injury by a steel bar was successfully treated by surgery.

Chief Complaint: The male patient was a 49-year-old builder.

The Effect of Deep Learning-Based QSM Magnetic Resonance Imaging on the Subthalamic Nucleus.

In order to study the influence of quantitative magnetic susceptibility mapping (QSM) on them. A 2.5D Attention U-Net Network based on multiple input and multiple output, a method for segmenting RN, SN, and STN regions in high-resolution QSM images is proposed, and deep learning realizes accurate segmentation of deep nuclei in brain QSM images.

Adipose-derived mesenchymal stem cells-derived exosome-mediated microRNA-342-5p protects endothelial cells against atherosclerosis.

Exosomes are reported to mediate several disease-related microRNAs (miRNAs) to affect the progression of diseases, including atherosclerosis. Here, we aimed to screen the atherosclerosis-associated miRNAs and preliminarily investigate the potential regulatory mechanism of atherosclerosis. First, the lesion model for human umbilical vein endothelial cells (HUVECs) was favorably constructed.

Overexpression of p53 delivered using recombinant NDV induces apoptosis in glioma cells by regulating the apoptotic signaling pathway.

Malignant glioma is the most common primary brain carcinoma in the world and has a poor survival rate. Previous studies have demonstrated that p53 dysfunction contributes to the development and severity of malignant glioma. It has also been demonstrated that Newcastle disease virus (NDV) may be a viable candidate for the treatment of various types of cancer.

MIS Score: Prediction Model for Minimally Invasive Surgery.

Background: Reports suggest that patients with spontaneous intracerebral hemorrhage (ICH) can benefit from minimally invasive surgery, but the inclusion criterion for operation is controversial. This article analyzes factors affecting the 30-day prognoses of patients who have received minimally invasive surgery and proposes a simple grading scale that represents clinical operation effectiveness.

Methods: The records of 101 patients with spontaneous ICH presenting to Qianfoshan Hospital were reviewed.

Car Windshield Wiper in the Brain: Case Report.

 Transorbital intracranial penetrating injury is rare. Damage caused by a huge metallic foreign body is very critical and life-threatening.  We report an extremely rare case of transorbital intracranial penetrating metal strip (a car windshield wiper), which has not previously been reported in the literature.

A supramolecular vesicle of camptothecin for its water dispersion and controllable releasing.

Camptothecin, as an antitumor drug, has shown significant antitumor activity against various cancers through the inhibition of topoisomerase I. However, its poor solubility severely limits the clinical applications. Here, we report a camptothecin supramolecular vesicle based on the host-guest interactions, which can uniformly disperse camptothecin into water and greatly enhance camptothecin aqueous solubility.

Strategy of directly employing paclitaxel to construct vesicles.

A class of aza-arm modified β-cyclodextrins were found to be able to trap paclitaxel (PTX), an effective but strongly hydrophobic anticancer drug, to form novel "supramolecular amphiphiles", which can further self-assemble into vesicular structures in aqueous solution. The obtained vesicles were characterized in detail by transmission electron microscopy (TEM), scanning electron microscopy (SEM), cryogenic transmission electron microscopy (cryo-TEM), and dynamic light scattering (DLS). The mechanism of the vesicular formation was suggested on the basis of the experimental results of nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermal analysis.

Effective regioselective protection of amino groups of lysine achieved by a supramolecular enzyme-mimic approach.

An enzymic method to protect selected amino group of lysine has been reported. This reaction proceeds smoothly under room temperature with high regioselectivity (up to 99%) and high yields (up to 90%). This work will pave the way for simple and selective protection of amino group of lysine in industry.

Self-assembled vesicles prepared from amphiphilic cyclodextrins as drug carriers.

Controlled self-assembly of amphiphilic cyclodextrin is always a challenging topic in the field of supramolecular chemistry, since it provides the spontaneous generation of well-defined aggregation with functional host sites with great potential applications in drug-carrier systems. β-Cyclodextrin modified with an anthraquinone moiety (1) was successfully synthesized. In the aqueous solution, 1 was found able to self-assemble into vesicles, which was characterized in detail by TEM, SEM, EFM, and DLS.
