With the development of social economy, the incidence of gout is increasing, which is closely related to people's increasingly rich diet. Eating a diet high in purine, fat, sugar and low-fibre for a long time further aggravates gout by affecting uric acid metabolism. The renal metabolism mechanism of uric acid has been thoroughly studied.

Objective: To explore the application value of white light image (WLI), endoscopic ultrasonography (EUS) and magnifying endoscopy with narrow band imaging (ME-NBI) in the endoscopic treatment of early gastric cancer (EGC), and to provide basis for decision-making in clinical diagnosis and treatment.

Methods: The clinicopathological data of EGC patients who underwent endoscopic submucosal dissection (ESD) at West China Hospital, Sichuan University between December 2013 and October 2020 were included. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of EGC invasive depth were compared between WLI and EUS.

Fibroblast-like synoviocytes (FLSs) in rheumatoid arthritis (RA) present proliferative and aggressive cell phenotype. RA-FLSs are the essential effector cells that lead to symptoms like synovial inflammation and joint destruction. Currently, the cause of RA-FLSs involving in the pathological process of RA remains unknown.

Fibroblast-like synoviocytes (FLSs) are the major effector cells that lead to rheumatoid arthritis (RA) synovitis and joint destruction. Our previous studies showed that Sonic Hedgehog (SHH) signaling pathway is involved in aberrant activation of RA-FLSs and inhibition of SHH pathway decreases proliferation and migration of RA-FLSs. The objective of this study was to investigate if the SHH pathway mediates proliferation and migration of RA-FLSs the mitogen-activated protein kinases/extracellular signal-regulated kinases (MAPK/ERK) signaling pathway.

Article Synopsis
  • The study introduces a flexible lactate biosensor utilizing l-lactate dehydrogenase and NAD+ immobilized on a nickel oxide film, enhanced by graphene oxide and magnetic beads for better performance.
  • The biosensor shows impressive sensitivity of 45.397 mV/mM and a high linearity of 0.992 within the lactate concentration range of 0.2 mM to 3 mM.
  • Electrochemical impedance spectroscopy results indicate that the modified biofilm has superior electron transfer efficiency compared to other configurations, and additional tests confirm its detection limits and resilience.

Background: To evaluate the clinical value of circulating tumor cells (CTC) count in peripheral venous blood of patients with non-small cell lung carcinoma (NSCLC).

Methods: A total of 50 NSCLC patients who were diagnosed in Wuxi No. 2 People's Hospital from January 2013 to December 2013 were selected as the NSCLC group, 35 patients with lung benign tumor as the benign group, and 28 healthy subjects as the normal control group.

Article Synopsis
  • Previous studies show that natriuretic peptides like NT-proBNP and BNP are reliable biomarkers for diagnosing heart failure (HF), especially in patients with pleural effusion.
  • This systematic review analyzed 14 studies focusing on the diagnostic accuracy of these peptides in blood and pleural fluid, finding high sensitivities and specificities for NT-proBNP.
  • The results suggest that both PF NT-proBNP and blood NT-proBNP have excellent diagnostic accuracy for HF, with PF NT-proBNP showing even better sensitivity and specificity compared to blood NT-proBNP.

Article Synopsis
  • The study examines the DNA methylation of the hsa-miR-124a gene in human gastric cancer tissues and its relationship with Rb and CDK6 protein expression and various clinical factors.
  • The researchers used methylation-specific PCR to assess DNA methylation in samples from 30 patients, finding a significantly higher methylation rate in cancer tissues compared to adjacent normal tissues.
  • Results indicated that hypermethylation of hsa-miR-124a is linked to increased levels of Rb and CDK6 proteins and correlates with several clinical factors such as tumor size and lymphatic metastasis, suggesting a role in the progression of gastric cancer.

Background And Purpose: Renal fibroblasts play a pivotal role in the development of tubulointerstitial fibrosis, a condition highly predictive of progression towards end-stage renal disease. The present study investigated the anti-mitogenic and anti-inflammatory effects of an inhibitor of inosine monophosphate dehydrogenase, mycophenolic acid (MPA) and the mechanisms underlying its action in normal rat kidney fibroblasts (49F cells).

Experimental Approach: Proliferation of 49F cells was studied by tetrazole 3-(4, 5-dimethylthiazol-2-yl-)-2,5-diphenyltetrazolium bromide (MTT) test, bromodeoxyuridine incorporation and flow cytometry.

Aldosterone secretion is subjected to dopaminergic regulation. Our previous study showed that both human D2 and D4 dopamine receptors (D2R and D4R) modulate aldosterone secretion, but in opposing directions. The inhibitory effect of D2R is mediated by attenuating protein kinase C-micro (PKC-micro) and calcium-dependent signaling.

Dyschromatosis symmetrica hereditaria (DSH) is a rare autosomal dominant cutaneous disorder characterized by a mixture of hyperpigmented and hypopigmented macules of various sizes on the extremities. Pathogenic mutations in the DSRAD gene have been identified. In this report, we identified a Chinese family with a three-generation pedigree of DSH, in which a novel heterozygous nucleotide G-->A transition was found.

Context: The mechanism associated with the overproduction of aldosterone by aldosterone-producing adenomas (APA) is unknown.

Objective: The objective of the study was to explore the role of the D2 dopamine receptor (D2R) on aldosterone synthesis and secretion and clarify the clinical importance of this role on aldosterone overproduction in APA.

Results: D2R expression in APA was examined in 24 patients and was much less than that in the nontumorous adrenal cortex.

Background & Objective: Clonality detection through amplifying immunoglobulin heavy chain (IgH) by polymerase chain reaction (PCR) is a useful tool in diagnosis of lymphoma, but the false negative rate is high, especially in paraffin-embedded tissues. This study was to explore the value of tumor tissue microdissection and combinational detection of IgH and immunoglobulin light chain (Ig kappa or Ig lambda) in diagnosis of non-Hodgkin's lymphoma (NHL).

Methods: Two pairs of conventional primers for IgH and T-cell receptor gamma (TCRgamma), 2 novel designed pairs of primers for Ig kappa and Ig lambda were used to detect 58 paraffin-embedded blocks, which had been diagnosed by pathology and histochemistry.

This experiment was conducted to investigate the effects of zinc sulfate and zinc methionine (Zn-Met) and their levels on apoptosis induced by glucocorticoid of thymocytes and the possible mechanism. Dexamethasone was used to make the apoptosis model of thymocytes; zinc sulfate and zinc methionine were supplemented to the medium at levels of 0, 50, 100, 500, and 1000 microM. The activity of cells, Cu,Zn superoxide dismutase (Cu,Zn-SOD), DNA ladder pattern, intracellular calcium concentration, and the percentage of apoptosis nuclei were determined.
