Cross-platform comparison of next-generation sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry for detecting KRAS/NRAS/BRAF/PIK3CA mutations in cfDNA from metastatic colorectal cancer patients

Nowadays, liquid biopsy using plasma cell-free DNA (cfDNA) is a crucial tool in cancer management. But it is still confusing which platform should be used as well as how to use cfDNA. In this study, we conducted a prospective study to compare two broad-coverage profiling platforms, next-generation sequencing (NGS) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF), on cfDNA analysis and explore the potential use of cfDNA in metastatic colorectal cancer (mCRC). Our results revealed the advantages of NGS assay over MALDI-TOF assay and indicated how to improve MALDI-TOF assay. Moreover, our results suggested the potential value of cfDNA analysis in monitoring treatment response in mCRC.

Clinical value of INSL3 in the diagnosis and development of diabetic nephropathy

We detected that the expression of INSL3 notably increased in both serum sample and high-glucose-treated SV40-MES-13 cells compared with samples from type 2 diabetic mellitus patients, healthy controls, and normal-glucose-treated SV40-MES-13. The receiver operating characteristic analysis clarified that INSL3 could discriminate DN patients from T2DM patients and healthy controls with the area under the curves (AUC) of INSL3 of 0.7017 (95% CI = 0.6284~0.7751) and 0.8176 (95% CI = 0.7529~0.8824), respectively. Furthermore, the correlation analysis elucidated that INSL3 expression was negatively correlated with DN diagnosis golden criterion eGFR (r = −0.6557, p < 0.0001). Finally, experiments in vitro claimed that the proliferation rate of SV40-MES-13 cells after high-glucose treatment was inhibited after INSL3 knockdown; in the meantime, the apoptosis rate significantly increased deeper suggested the potential of INSL3 in DN diagnosis and development. Collectively, this study demonstrated the clinical significance of INSL3 in diagnosing and developing DN.

MALT1 positively correlates with Th1 cells, Th17 cells, and their secreted cytokines and also relates to disease risk, severity, and prognosis of acute ischemic stroke

Background: This study aimed to explore the association of mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) with acute ischemic stroke (AIS) risk and also to explore its association with T helper type 1 (Th1) cells, Th17 cells, disease severity, and prognosis in AIS patients. Methods: One hundred twenty first-episode AIS patients and 120 non-AIS patients with high-stroke-risk factors (as controls) were recruited. Besides, in the cluster of differentiation 4-positive (CD4+) T cells, the MALT1 gene expression was detected by reverse transcription quantitative polymerase chain reaction; meanwhile, Th1 and T h17 were detected by flow cytometry. Moreover, serum interferon (IFN)-γ and interleukin (IL)-17 were determined by enzyme-linked immunosorbent assay. Results: MALT1 expression was increased in AIS patients compared with controls and also it could differentiate AIS patients from controls, with an area under curve of 0.905 (95% confidence interval: 0.869-0.941). In AIS patients, MALT1 positively correlated with Th1 cells, Th17 cells, IFN-γ, and IL-17. Besides, MALT1 positively correlated with the National Institutes of Health Stroke Scale score. Furthermore, the Kaplan-Meier curve and univariate Cox’s regression analyses showed no correlation of MALT1 high expression with recurrence-free survival (RFS) in AIS patients, although after adjustment using multivariant Cox’s regression, high MALT1 expression independently correlated with worse RFS in AIS patients. Conclusion: MALT1 expression is increased and positively correlates with disease severity, Th1 cells, and Th17 cells, whose high expression severs as an independent risk factor for worse RFS in AIS patients.

PHD finger protein 19 expression in multiple myeloma: Association with clinical features, induction therapy outcome, disease progression, and survival

Background: PHD finger protein 19 (PHF19), also known as polycomb-like protein 3 (PCL3), promotes the progression of multiple myeloma (MM) and drug resistance; however, its role in the management of MM remains unclear. Therefore, we aimed to elucidate the correlation between PHF19 expression and treatment response, disease progression, and survival of patients with MM. Methods: Plasma cells derived from the bone marrow of 101 patients with de novo MM were collected prior to induction therapy, as were plasma cells derived from the bone marrow of 30 healthy donors. PHF19 expression in plasma cells was analyzed using quantitative reverse transcription polymerase chain reaction. Furthermore, the response to induction therapy, progression-free survival (PFS), and overall survival (OS) were assessed. Results: PHF19 expression tends to be upregulated more often in MM patients than in healthy donors (< 0.001) and can accurately predict MM risk (area under curve [AUC], 0.916; 95% confidence interval [CI], 0.869–0.962). Furthermore, elevated PHF19 expression was correlated with higher International Staging System (ISS) (= 0.036) and revised ISS stages (= 0.035). In addition, MM patients who achieved complete response (CR) exhibited reduced PHF19 compared to those who did not (= 0.028). Moreover, increased PHF19 expression was correlated with unfavorable PFS (= 0.006) and OS (= 0.027) rates. Furthermore, the results of multivariate Cox analysis also revealed that PHF19 high expression was independently associated with a reduced PFS rate (hazard ratio: 2.025, = 0.028). Conclusion: Increased PHF19 expression is correlated with poor induction therapy response and unfavorable long-term prognosis of MM.

Preliminary exploration on the serum biomarkers of bloodstream infection with carbapenem-resistant Klebsiella pneumoniae based on mass spectrometry

Carbapenem-resistant K. pneumoniae (CRKP) bloodstream infections (BSI) must be rapidly identified to improve patient survival rates. To better facilitate the identification of CRKP BSI, we interrogated blood samples using a mass spectrometry profiling approach to identify relevant diagnostic biomarkers. We successfully established a serum peptide-based diagnostic model that distinguished clinical CRKP BSI samples from normal healthy controls. The application of MALDI-TOF MS to measure serum peptides therefore represents a promising approach for early BSI diagnosis of BSI, especially for multidrug-resistant bacteria where identification is urgent. Although the relationships between these biomarkers and drug-resistant bacterial infections are not clear, these findings provide new clues for the search for biomarkers of drug-resistant bacterial infection. We will continue to explore the underlying scientific mechanisms associated between changes in these proteins and CRKP BSIs in our future research.

Chaperonin-containing tailless complex polypeptide 1 subunit 6A correlates with increased World Health Organization grade, less isocitrate dehydrogenase mutation, and deteriorative survival of astrocytoma patients

Chaperonin-containing tailless complex polypeptide 1 subunit 6A (CCT6A) is reported to be an efficient prognostic biomarker in various cancers, but it is rarely reported in astrocytoma. Thus, this study aimed to evaluate the expression of CCT6A and its correlation with disease features and prognosis in astrocytoma patients. Totally, 198 astrocytoma patients who received surgery treatment were enrolled. CCT6A protein expression was determined in the tumor tissues fixed in formalin and embedded in paraffin (FFEP) by immunohistochemistry (IHC) assay. In addition, 133 out of 198 astrocytoma patients had fresh tumor tissues frozen in the liquid nitrogen for the determination of CCT6A mRNA expression by reverse transcription-quantitative polymerase chain reaction. Sixty-nine (34.8%), 70 (35.4%), 46 (23.2%), and 13 (6.6%) astrocytoma patients had the CCT6A immunohistochemistry (IHC) score of 0–3, 4–6, 7–9, and 10–12, respectively. CCT6A protein expression was correlated with increased World Health Organization (WHO) grade (P < 0.001) and less isocitrate dehydrogenase (IDH) mutation (P = 0.002); meanwhile, CCT6A mRNA expression was only related to elevated WHO grade (P = 0.001). However, CCT6A protein and mRNA expression were not correlated with other clinical features and subsequent treatment modalities (all P > 0.05). Moreover, CCT6A protein high and CCT6A mRNA high were related to shorter accumulating overall survival (OS; both P < 0.05). CCT6A protein high was an independent factor for predicting the worse OS (hazard ratio: 1.821, P = 0.012). CCT6A correlates with elevated WHO grade and less IDH mutation; besides, CCT6A high expression is independently associated with unfavorable accumulating OS of astrocytoma patients.

A new method for anti-negative interference of calcium dobesilate in serum creatinine enzymatic analysis

The serum creatinine quantitative method SOE was negatively interfered with by the commonly used drug calcium dobesilate, resulting in lower than the actual value. The new BG reagent laccase was added to prevent the generation of negative interference and make the detection more accurate. Schematic diagram of creatinine detection of the new BG reagent. SOD: sarcosine oxidase. 4-AAP: 4-aminophenazone. POD: peroxidase. HTIB: 2,4,6-triiodo-3-hydroxybenzoic acid. Qic: quinoneimine chromogen. Calcium dobesilate is a strong reducing agent that consumes H2O2 during the reaction, resulting in decreased QIC of the final chromatographic substance. Laccase is a strong oxidant that can oxidize calcium dobesilate in advance before H2O2 is produced so that H2O2 will not be consumed and negative interference can be avoided.

Abnormal regulation of microRNAs and related genes in pediatric β-thalassemia

We performed microRNA sequencing to identify the microRNA expression profiling of pediatric β-thalassemia. Totally, 530 microRNAs were identified. Based on criteria of fold change >1.5 and p-value <0.05, 111 microRNAs were upregulated in β-thalassemia patients, while 85 microRNAs were downregulated in β-thalassemia patients. Those microRNAs could clearly distinguish the normal cohorts from the β-thalassemia patients. Hsa-miR-2100-3p, hsa-microRNA-15a-5p, hsa-microRNA-16-5p, and hsa-miR-503-5p were all downregulated in pediatric β-thalassemia patients. We also found five let7 microRNAs hsa-let-7b-5p, hsa-let-7i-5p, hsa-let-7f-5p, hsa-let-7e-5p, and hsa-let-7d-5p and were downregulated in pediatric thalassemia patients.

The diagnostic value of the combination of hemoglobin, CA199, CA125, and HE4 in endometriosis

This study retrospectively analyzed the differences in the peripheral blood cells and their derivative parameters and tumor biomarkers between the patients with endometriosis and healthy people, and established a more efficient combined diagnostic model based on HGB, CA199, CA125, and HE4. The combined diagnostic model reached a sensitivity of 85.4%, a specificity of 78.83%, and an area under the curve of 0.900, which may provide a novel approach for the early non-invasive diagnosis of endometriosis.

AC016405.3 functions as an oncogenic long non-coding RNA by regulating ERBB3 via sponging miR-22-3p in breast cancer

AC016405.3 is involved in BRCA progression by up-regulating ERBB3 expression via miR-22-3p. BRAC cells (MCF7 and ZR7530) were co-transfected si-AC016405.3 with empty vector (EV) or ERBB3 overexpression vector (ERBB3). The proliferation of BRAC cells from different groups was examined by (A) CCK-8 and (B) colony formation assays. (C) Wound-healing assay assessed the migration ability of BRAC cells from different groups. (D) Transwell assay evaluated both the migration and invasion of BRAC cells from different groups. (E) A schematic diagram exhibited the proposed mechanism that cytoplasmic AC016405.3 sponges miR-22-3p to promote ERBB3 expression thus contributes to BRCA progression. Note: **< 0.01 and ***< 0.005.

Reduced expression of circRNA hsa_circ_001888 in gastric cancer and its clinical significance

This study aimed to identify the relationship between gastric cancer (GC) and a new circRNA named hsa_circ_001888. The results indicated that hsa_circ_001888 was significantly downregulated in GC cell lines, tissues and plasma samples compared to control samples. Hsa_circ_001888 may serve as a potential biomarker in the diagnosis of GC with high degrees of specificity, sensitivity and accuracy.

Sestrin2 and Beclin1 levels in Polycystic Ovary Syndrome

This study attempted to evaluate the plasma concentrations of Sestrin2 and Beclin1 in women with PCOS and healthy controls, and to explore the clinical value of these proteins as novel biomarkers for PCOS. Plasma sestrin2 levels of the subjects with PCOS (40.74 [24.39–257.70]) were significantly lower than that of healthy subjects (255.78 [25.46–528.66]; p-value = 0.040). A cut-off value of 420.5 ng/L had an appropriate sensitivity (83.87%) and specificity (46.88%) for discriminating individuals with and without PCOS. There were no statistically significant differences between the two groups concerning plasma levels of beclin1. Our findings highlight the dysregulation of sestrin2 as a marker of autophagy in PCOS and its usefulness as a novel biomarker for PCOS.

The clinical value of high fluorescent lymphocytes and smudge cells in the diagnosis of infectious mononucleosis

HFLC% can be used for auxiliary diagnosis of IM, thereby saving time and reducing cost of smear and manual classification. HFLC% assists the diagnosis of IM with the following advantages. First, this indicator has high specificity and sensitivity for the diagnosis of IM, which can effectively avoid missed diagnosed. Second, HFLC%, as one of the blood routine indicators, can be obtained directly from the automatic blood analyzer. It does not increase additional economic burdens and manual operations. It has better adaptability and superiority, and can prompt clinical diagnosis and treatment earlier. In addition, when the number of smudge cells in the peripheral blood increases, the doctor should be alert to the possibility of IM.
