Thrombospondin 2 is a tumor stemness protein marker based on the cluster analysis combined with immune infiltration in gastric cancer.

Platelet reactive protein 2 (PRP2) is closely related to the characteristics of tumor stem cells. Its role in cancer development and metastasis has received increasing attention, especially its interaction with the immune microenvironment. The study used cluster analysis to extract expression data of multiple cancer types from public databases, and combined with immune infiltration analysis, to evaluate the expression level of PRP2 and its correlation with different immune cell infiltration.

Expression feature and prognostic function of a novel immune checkpoint Siglec-15 in human colorectal cancer.

Background: Sialic acid-bound immunoglobulin lectin 15 (Siglec-15) plays an important role in the development of cancer. However, the association between Siglec-15 expression and clinicopathological characteristics of colorectal cancer (CRC) has not been fully investigated.

Methods: In this present study, a number of bioinformatics analyses were performed to provide an overview and detailed characteristics of Siglec-15.

The expression characteristic and prognostic role of Siglec-15 in lung adenocarcinoma.

Sialic acid-binding immunoglobulin-like lectin-15 (Siglec-15) has been identified as an immune suppressor and a promising candidate for immunotherapy of cancer management. However, the association between Siglec-15 expression and clinicopathological features of lung adenocarcinoma (LUAD), especially the prognostic role, is not fully elucidated. In this present study, a serial of bioinformatics analyses in both tissue and cell levels were conducted to provide an overview of Siglec-15 expression.

Prognostic Role of Pretreatment Prognostic Nutritional Index in Advanced Lung Cancer Patients Receiving First-Line Immunotherapy: A Meta-Analysis.

The aim of this study was to further explore the association between pretreatment prognostic nutritional index (PNI) and survival among advanced lung cancer patients who received the first-line immunotherapy based on current relevant studies. Several databases were searched up to July 17, 2023. Progression-free survival (PFS) and overall survival (OS) were primary outcomes and the hazard ratios (HRs) with 95% confidence intervals (CIs) were combined.

HDAC3 Inhibitor RGFP966 Ameliorated Neuroinflammation in the Cuprizone-Induced Demyelinating Mouse Model and LPS-Stimulated BV2 Cells by Downregulating the P2X7R/STAT3/NF-κB65/NLRP3 Activation.

Suppression of excessive microglial overactivation can prevent the progression of multiple sclerosis (MS). Histone deacetylases 3 inhibitor (HDAC3i) has been demonstrated to exert anti-inflammatory effects by suppressing microglia (M1-liked) activation. Here, we demonstrate that the RGFP966 (a selective inhibitor of HDAC3) protects white matter after cuprizone-induced demyelination, as shown by reductions in neurological behavioral deficits and increases in myelin basic protein.

Expression and Clinical Significance of lncRNA OSER1-AS1 in Peripheral Blood of Patients with Non-Small Cell Lung Cancer.

Non-small cell lung cancer (NSCLC) is a malignant cancer worldwide. Long non-coding RNAs (lncRNAs) have emerged as key players in the development and progression of NSCLC, and may be potential biomarkers of NSCLC. Here, we investigated the clinical significance of lncRNA oxidative stress responsive serine rich 1 antisense RNA 1 (OSER1-AS1) in peripheral blood of patients with NSCLC.

Surgical procedure of segmentectomy as a possible cause of postoperative cerebral embolism: a case report.

Background: Cerebral embolism after lobectomy is a life-threatening complication during the early postoperative period. However, it is unclear if cerebral embolism can develop after segmentectomy.

Case Presentation: We experienced a case of a 37-year-old man who demonstrated early symptom of acute ischemic stroke in early postoperative period after right upper posterior segmentectomy and performed intra-arterial mechanical thrombectomy (IAMT) successfully.

Response of various conduit arteries in tachycardia- and volume overload-induced heart failure.

Although hemodynamics changes occur in heart failure (HF) and generally influence vascular function, it is not clear whether various HF models will affect the conduit vessels differentially or whether local hemodynamic forces or systemic factors are more important determinants of vascular response in HF. Here, we studied the hemodynamic changes in tachycardia or volume-overload HF swine model (created by either high rate pacing or distal abdominal aortic-vena cava fistula, respectively) on carotid, femoral, and renal arteries function and molecular expression. The ejection fraction was reduced by 50% or 30% in tachycardia or volume-overload model in four weeks, respectively.

Increased aortic stiffness elevates pulse and mean pressure and compromises endothelial function in Wistar rats.

An increase in pulse pressure (PP) is highly associated with hypertension. The goal of this study was to determine the effect of increased aortic stiffness on PP and endothelial dysfunction as precursors to hypertension. A rat model of suddenly increased aortic stiffness by use of a nonconstrictive restraint (glue coating) on aortic surface was created to investigate the change of PP and mean arterial pressure (MAP).

Endothelial actin depolymerization mediates NADPH oxidase-superoxide production during flow reversal.

Slow moving blood flow and changes in flow direction, e.g., negative wall shear stress, can cause increased superoxide (O2(·-)) production in vascular endothelial cells.

[Chemical constituents from roots of Ferula sinkiangensis].

Objective: To study the chemical constituents of the roots of Ferula sinkiangensis.

Method: Compounds were isolated by repeated chromatography on silica gel. Their structures were elucidated by chemical and spectroscopic methods.

Sesquiterpene coumarins from the roots of Ferula sinkiangensis and Ferula teterrima.

Three new natural sesquiterpene coumarins, isofeterin (1), lehmannolol (3), sinkianone (4), and one known compound, lehmannolone (2), were isolated from the roots of Ferula teterrima and Ferula sinkiangensis. Their chemical structures were established on the basis of spectroscopic analysis, including X-ray crystallography and CD spectrum measurements for determining the absolute configuration of compound 2.

Objective: To establish the control substance of plant drug (CSPD) of Coptis chinensis Franch. and its proton nuclear magnetic resonance (1H NMR) and high performance liquid chromatography (HPLC) fingerprints for the purpose of original identification.

Methods: The CSPD and their 1H NMR and HPLC fingerprints of Coptis chinensis were obtained by standardized procedure.
