The Method of Lipemia Clearance Should be Based on the Characteristics and the Method of Testing in the Emergency Laboratory.

Background: This study aimed to compare the lipemia removal efficiency of highspeed centrifugation, lipid scavengers, and dilution for biochemical analytes.

Methods: We collected 30 cases of lipemic plasma in an emergency laboratory and divided them into 4 aliquots. Lipemia was removed by highspeed centrifugation, lipid scavenger, dilution, and ultracentrifugation, then analytes were measured by an AU5800 analyzer.

PCR combined with serologic testing improves the yield and efficiency of SARS-CoV-2 infection hunting: A study in 40,689 consecutive overseas arrivals.

Background: The global epidemiological situation of COVID-19 remains serious. The rapid hunting of SARS-CoV-2 infection is the key means for preventing transmission.

Methods: A total of 40,689 consecutive overseas arrivals were screened for SARS-CoV-2 infection based on PCR and serologic testing.

Unspecific reactivity must be excluded in COVID-19 epidemiological analyses or virus tracing based on serologic testing: Analysis of 46,777 post-pandemic samples and 1,114 pre-pandemic samples.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019 (COVID-19). Serologic testing is complementary to nucleic acid screening to identify SARS-CoV-2. This study aimed to evaluate unspecific reactivity in SARS-CoV-2 serologic tests.

MicroRNA miR-425 promotes tumor progression by inhibiting Dickkopf-related protein-3 in gastric cancer.

Gastric cancer is a prevalent yet heterogeneous disease which ranks as the fifth most common cancer in the world. Dietary habit, genetic background, infections were the risk factors of gastric cancer. MicroRNA miR-425 is highly expressed in gastric cancer, but little attention has been devoted to the mechanism of miR-425 in tumorigenesis.

Comparing the diagnostic value of bronchoalveolar lavage fluid galactomannan, serum galactomannanan, and serum 1,3-β-d-glucan in non-neutropenic respiratory disease patients with invasive pulmonary aspergillosis.

The incidence of invasive pulmonary aspergillosis (IPA) is increasing higher in non-neutropenic patients. This study aimed to assess the diagnostic performance of bronchoalveolar lavage fluid (BALF). Galactomannan (GM), serum GM, and 1,3-β-d-glucan (BDG) in non-neutropenic respiratory disease patients with IPA.

Silencing of DHX32 increases the proliferation of liver cancer cells.

Background: Liver cancer ranks fifth in malignancy incidence globally and is the second leading cause of cancer-related death in China. Chronic hepatitis B or C infection and alcohol abuse have been identified to be the major risk factors for liver cancer development. Some evidence implicates DHX32 as being critically involved in tumor progression.

ProGRP AS A NOVEL BIOMARKER FOR THE DIFFERENTIAL DIAGNOSIS OF MEDULLARY THYROID CARCINOMA IN PATIENTS WITH THYROID NODULES.

To investigate the release of progastrin-releasing peptide (ProGRP) in patients with thyroid nodules and the value of ProGRP in fine-needle aspirate washout fluid (FNA-ProGRP) in the differential diagnosis between medullary thyroid carcinoma (MTC) and non-MTC thyroid nodules. We investigated 2,446 healthy persons and 212 patients with 235 thyroid nodules. They were classified into healthy, nodular goiter, chronic thyroiditis, thyroid follicular neoplasm, papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma.

The E2F3/miR-125a/DKK3 regulatory axis promotes the development and progression of gastric cancer.

Background: Gastric cancer (GC) is one of the most common malignant tumours with high mortality and metastasis rates. E2F3, miR-125a and DKK3 have been reported to be involved in various cancer types, but their detailed roles in GC have not been fully understood.

Methods: A QRT-PCR assay was used to examine the expression of E2F3, miR-125a and DKK3 in metastatic and nonmetastatic GC tissues.
