Background: Next-generation sequencing of the metagenome (mNGS) is increasingly used in pathogen diagnosis for infectious diseases due to its short detection time. The time for Oxford Nanopore Technologies (ONT) sequencing-based etiology detection is further shortened compared with that of mNGS, but only a few studies have verified the time advantage and accuracy of ONT sequencing for etiology diagnosis. In 2022, a study confirmed that there was no significant difference in sensitivity and specificity between ONT and mNGS in suspected community-acquired pneumonia patients, which there was no clinical study verified in patients with SHAP.

Chronic pulmonary aspergillosis (CPA) is a chronic and progressive fungal disease with high morbidity and mortality. Avoiding diagnostic delay and misdiagnosis are concerns for CPA patients. However, diagnostic practice is poorly evaluated, especially in resource-constrained areas where Aspergillus antibody testing tools are lacking.

Article Synopsis
  • * This study evaluated noncultural diagnostic methods, specifically the CSF galactomannan (GM) test and metagenomic next-generation sequencing (mNGS), to improve diagnosis in patients with suspected CNS aspergillosis.
  • * Results showed that using both tests together significantly enhanced diagnostic accuracy, particularly in encephalitis patients, highlighting their potential value in clinical settings.

In recent years, the important role of long non‑​coding RNAs (lncRNAs) in the development of liver cancer has received increasing attention. The abnormal expression level of long non‑coding RNAs has been associated with the occurrence and development of liver cancer. However, the role and molecular mechanisms of lncRNAs in the development and progression of liver cancer are not fully understood.

Background: The correlation between tumor markers (TM) and TNM stage of non-small-cell lung cancer (NSCLC) has not been widely reported.

Methods: TM levels (CEA, CA125, CA15-3, CA19-9, CA72-4, CYFRA21-1, and SCC-Ag) in 424 cases of lung adenocarcinoma (LAC), 166 cases of lung squamous cell carcinoma (LSCC), and 103 cases of benign chest disease (BCD) were analyzed before treatment.

Results: By correlation analysis, CEA, CA125, CA15-3, CA19-9, CA72-4, CYFRA21-1, and SCC-Ag were correlated with T stage of LAC ( = 0.

The present study was designed to investigate the anti-sepsis effects of physcion 8-O-β-glucopyranoside (POG) isolated from Rumex japonicas and explore its possible pharmacological mechanisms. POG was extracted from R. japonicas by bioactivity-guided isolation with the anti-sepsis agents.

Background: Endothelial dysfunction is the basic and original sign of atherogenesis. Some evidences show that C-reactive protein (CRP) and perivascular adipose tissue (PVAT) play a pivotal role in atherosclerosis. However, the effects of CRP on atherosclerosis and the related mechanisms require elucidation.

The oligodendroglioma (OG) type of glial cell tumors accounts for 2-5% of primary brain neoplasms and 4-15% of gliomas diagnosed worldwide. Allelic losses on 1p, or on 1p and 19q, correlate with chemotherapy response and good prognosis in OG patients; however, the underlying mechanisms are not yet clearly defined. Therefore, we utilized a quantitative proteomics strategy that combined 8-plex isobaric tags for relative and absolute quantitation (iTRAQ) labeling and two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC/MS/MS) to identify molecular signatures, reveal mechanisms, and develop predictive markers of OG patients with 1p loss of heterozygosity (LOH).

Objective: To investigate the effect of intraluminal administration of ulinastatin (a protease inhibitor) in the intestine on intestinal inflammation in rats with hemorrhagic shock.

Methods: Twenty-eight Wistar rats were randomized into control group (A), intestinal saline perfusion group (B), ulinastatin intestinal perfusion group (C), and intravenous ulinastatin injection group (D) (n=7). The mean arterial blood pressure (MAP) and survival time of the rats were recorded.

Objectives: This study try to subclassify breast cancer into different prognostic subgroups according to immunohistochemical algorithm and discuss the relationship between subtypes and biological and clinical behavior and prognosis.

Methods: One hundred and twenty-eight cases of infiltrative ductal carcinoma were studied using immunohistochemical staining with an antibody panel of ER, PR, HER2 and CK5/6 and subclassified referring to previous reports, and the 9 cases of HER2 positive subtype were tested using FISH.

Results: The expression of ER, PR, HER2, and CK5/6 was detected in 67%, 45%, 27% and 27% cases, respectively.

Objective: To investigate the pharmacokinetics and pharmacodynamics of poly (lactide-co-glycolide) microspheres containing ropivacaine and dexamethasone for sciatic nerve block in mice.

Methods: A total of 165 female mice were randomly assigned into 3 groups, namely dexamethasone-loaded ropivacaine microsphere group (group A, n=55), ropivacaine microsphere group (group B, n=55) and PLGA microsphere group (group C, n=55). The mice received surgical implantation of the corresponding preparations near the sciatic nerve at the dose of 400 mg/kg.

Special AT-rich sequence binding protein (SATB) 1 has been proposed to act as a determinant for the acquisition of metastatic activity by controlling expression of a specific set of genes that promote metastatic activity. Here we found that SATB1 expression is upregulated in multidrug-resistant breast cancer cells that exhibit higher invasive potential than the parental cells. Apart from accelerating metastasis and inducing epithelial-mesenchymal transition, SATB1 was demonstrated to confer resistance to both P-glycoprotein-related and P-glycoprotein-non-related drugs on MCF7 cells, which was accompanied by decreasing accumulation of adriamycin in SATB1-overexpressing transfectants.

Purpose: Besides its therapeutic effects, chemotherapeutic agents also enhance the malignancy of treated cancers in clinical situations. Recently, epithelial-mesenchymal transition (EMT) has attracted attention in studies of tumor progression. We aimed to test whether transient Adriamycin treatment induces EMT and apoptosis simultaneously in cancer cells, clarify why the same type of cells responds differentially (i.
