A new risk assessment model of venous thromboembolism by considering fuzzy population.

Background: Inpatients with high risk of venous thromboembolism (VTE) usually face serious threats to their health and economic conditions. Many studies using machine learning (ML) models to predict VTE risk overlook the impact of class-imbalance problem due to the low incidence rate of VTE, resulting in inferior and unstable model performance, which hinders their ability to replace the Padua model, a widely used linear weighted model in clinic. Our study aims to develop a new VTE risk assessment model suitable for Chinese medical inpatients.

Electroacupuncture Promotes Gastric Motility by Suppressing Pyroptosis via NLRP3/Caspase-1/GSDMD Signaling Pathway in Diabetic Gastroparesis Rats.

Objective: To investigate the mechanism of electroacupuncture (EA) in treating diabetic gastroparesis (DGP) by inhibiting the activation of Nod-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasome and pyroptosis mediated via NLRP3/cysteinyl aspartate specific proteinase-1 (caspase-1)/gasdermin D (GSDMD) signaling pathway.

Methods: Forty Sprague-Dawley rats were randomly divided into 4 groups including the control, DGP model, EA, and MCC950 groups. The DGP model was established by a one-time high-dose intraperitoneal injection of 2% streptozotocin and a high-glucose and high-fat diet for 8 weeks.

Analysis of risk factors for postoperative deep vein thrombosis after craniotomy and nomogram model construction.

Background: Deep vein thrombosis (DVT) of the lower extremity is one of the most common postoperative complications, especially after craniocerebral surgery. DVT may lead to pulmonary embolism, which has a devastating impact on patient prognosis. This study aimed to investigate the incidence and risk factors of DVT in the lower limbs following craniocerebral surgery.

Optimized risk stratification strategy for glioma patients based on the feature genes of poor immune cell infiltration patterns.

Background: Gliomas, originating from glial cells within the brain or spinal cord, are common central nervous system tumors with varying degrees of malignancy that influence the complexity and difficulty of treatment. The current strategies, including traditional surgery, radiotherapy, chemotherapy, and emerging immunotherapies, have yielded limited results. As such, our study aims to optimize risk stratification for a more precise treatment approach.

Inflammatory myofibroblastic tumor of the central nervous system: A case report.

Background: An inflammatory myofibroblastic tumor (IMT) occurring in the central nervous system is very rare, and thus its pathogenesis is unknown. This case report and literature review aimed to explore the pathogenesis, clinical features, imaging findings, pathological characteristics, immunohistochemical characteristics, diagnoses, treatments, and risks of postoperative recurrence of IMT in the central nervous system.

Case Summary: A 67-year-old woman was admitted to the hospital with an exophthalmic protrusion and double vision in the left eye that had persisted for 3 mo.

Comparing different venous thromboembolism risk assessment machine learning models in Chinese patients.

Objective: Venous thromboembolism (VTE) is a fatal complication and the most common preventable cause of death in hospitals. The risk-to-benefit ratio of thromboprophylaxis depends on the performance of the risk assessment model. A linear model, the Padua model, is recommended for medical inpatients in the United States but is not suitable for Chinese inpatients due to differences in race and disease spectrum.

Abnormal expression of menin predicts the pathogenesis and poor prognosis of adult gliomas.

Several brain tumors is closely related to the disorder of chromatin histone modification, whereas the epigenetic mechanisms of the incidence of highly malignant adult glioma is not yet deeply studied. Deletion or mutation of the MEN1 gene, which encodes the epigenetic regulator menin, specifically induces poorly differentiated neuroendocrine tumors; however, the biological and clinical importance of MEN1 in the nervous system remains poorly understood. Menin expression was robustly activated in 44.

HOXA10‑AS: A novel oncogenic long non‑coding RNA in glioma.

Glioma is the most common primary malignant tumor of the central nervous system. Emerging evidence has demonstrated that long non‑coding RNAs (lncRNAs) serve a major role of regulation in various types of human cancer, including glioma. However, the biological roles of thousands of lncRNAs remain unknown and require further identification.

Can the lower urinary tract storage symptoms be completely resolved after plasmakinetic enucleation of the prostate?

The aim of this study was to determine whether the lower urinary tract storage symptoms of benign prostatic obstruction (BPO) could be completely resolved after plasmakinetic enucleation of the prostate (PKEP) and the possible predictors of persistent symptoms. Two hundred and sixty-seven cases of BPO performed PKEP from July 2008 to June 2009 were retrospectively analyzed. Five-year postoperative data were collected and compared with the preoperative data.

[Effects of purine nucleotide on the expressions of FSH and LH and the ultrastructure of endocrine cells in the pituitary gland of heroin-addicted male rats].

Objective: To investigate the effects of purine nucleotide on the expressions of follicle-stimulating hormone (FSH) and luteotrophic hormone (LH) and the ultrastructures of the distal somatotrophic and gonadotrophic cells in the pituitary gland of heroin-addicted and -withdrawal rats.

Methods: Ninety-two male Wistar rats were randomly divided into a control group (ip saline for 14 d), a nucleotide group (ip AMP and GMP for 10 d), a heroin group (ip heroin for 10 d), a heroin + nucleotide group (ip AMP and GMP + heroin for 10 d), a 3 d withdrawal group (ip heroin for 10 d and killed at 14 d), a 9 d withdrawal group (ip heroin for 10 d and killed at 20 d), a 3 d nucleotide group (ip nucleotide for 3 d after 10 d heroin administration and killed at 14 d), and a 9 d nucleotide group (ip nucleotide for 9 d after 10 d heroin administration and killed at 20 d). Changes in the mRNA expressions of FSH and LH in the pituitary gland of the rats were analyzed by semi-quantitative RT-PCR, and alterations in the ultrastructures of the distal somatotrophic and gonadotrophic cells were observed under the microscope.

Large cystic hypoglossal schwannoma with fluid-fluid level: a case report.

Hypoglossal schwannomas are rare skull base tumors. Furthermore, cystic hypoglossal schwannomas are extremely uncommon. We report the first case of a large cystic hypoglossal schwannoma with a fluid-fluid level.

[Correlation of the expressions of VEGF-C and VEGFR-3 to the pathological grade of prostate cancer].

Objective: To investigate the correlation of the expression of VEGF-C and VEGFR-3 to the pathological grade of human prostate cancer.

Methods: Immunohistochemistry was used to detect the expression of VEGF-C and VEGFR-3 in 25 cases of prostate cancer tissues.

Results: The total positivity rates of VEGF-C and VEGFR-3 were 80% and 76% in these cancer tissues, respectively.

Brain stem candidiasis mimicking cerebellopontine angle tumor.

Background: Infectious process can mimic cerebral tumors. We present the first report of a fugal infection in brainstem mimicking cerebral tumors in the literature.

Tempol, one of nitroxides, is a novel ultraviolet-A1 radiation protector for human dermal fibroblasts.

Background: Nitroxide has been reported to have antioxidant and some photoprotective properties. Exposure of skin to ultraviolet-A1 (UVA1, 340-400 nm) can lead to formation of reactive oxygen species, reduction in collagen, and increased expression of matrix metalloproteinases (MMPs).

Objective: The goal of this research was to determine the effects of 4-hydroxy-Tempo (Tempol), one of nitroxides, in the presence of UVA1 on cytotoxicity, superoxide dismutase enzyme (SOD) activity, lipid peroxidation, and expression of collagen I, collagen III and MMP-1, MMP-3 in human dermal fibroblasts in vitro.

[Assessment of exposure to extremely low frequency magnetic field emitted from monitors].

Objectives: To investigate intensity of extremely low frequency magnetic field (ELFMF) emitted from cathode-ray tubes (CRT) of monitors in various directions and to find ways to avoid its influence.

Methods: Two hundred CRT monitors and 10 monitors with liquid-crystal display (LCD) were selected. Their ELFMF was detected for three times in front of the monitor at an interval of every 5 cm from 0 cm to 50 cm, as well as at various directions from the monitor.
