ABSTRACT

According to the latest global cancer statistics, colorectal cancer (CRC) has emerged as the third most prevalent malignant tumor across the globe. In recent decades, the medical field has implemented several levels of CRC screening tests, encompassing fecal tests, endoscopic examinations, radiological examinations and blood tests. Previous studies have shown that leukocyte immunoglobulin-like receptor B2 (LILRB2) is involved in inhibiting immune cell function, immune evasion, and promoting tumor progression in acute myeloid leukemia and non-small cell lung cancer. However, its interaction with CRC has not been reported yet. Recently, a study published in the World Journal of Gastroenterology revealed that LILRB2 and its ligand, angiopoietin-like protein 2, are markedly overexpressed in CRC. This overexpression is closely linked to tumor progression and is indicative of a poor prognosis. The study highlights the potential of utilizing the concentration of LILRB2 in serum as a promising biomarker for tumors. However, there is still room for discussion regarding the data processing and analysis in this research.

ABSTRACT

The prevalence of chronic kidney disease(CKD) increases year by year and has become a highly prevalent disease, seriously affecting the quality of life of patients and bringing heavy family burden. There are many diseases causing CKD, including va-rious primary and secondary glomerulonephritis, renal tubular injury, and renal vascular lesions. Although routine medical treatment for CKD can alleviate the clinical symptoms to a certain extent, it is sometimes difficult to prevent the progression of CKD. Traditional Chinese medicine(TCM) is advantageous in high safety, few adverse reactions, and definite clinical efficacy in the treatment of CKD. The active components contained can play a synergistic effect through multiple pathways and multiple targets to delay disease progression, but its mechanism of action has not been fully elucidated. As revealed by the literature in this field in China and abroad, abnormal mitophagy is a common feature of the pathogenesis of CKD of different types. In recent years, a large number of studies have proved that the regulation of mitophagy through the PINK1/Parkin signaling pathway and mitophagy receptor pathway could delay the progression of CKD and protect renal function. Therefore, the regulation of mitophagy by TCM in the prevention and treatment of CKD through related pathways has become a potential therapeutic target in recent years. This paper reviewed the research articles on the definite efficacy of TCM in preventing and treating CKD by regulating mitophagy through relevant pathways to provide new targets and stra-tegies for preventing and treating CKD and delaying their entry into end-stage renal diseases.

ABSTRACT

A new acentric barium borate, Ba2B10O16(OH)2·(H3BO3)(H2O) (1), was synthesized via a hydrothermal process. Compound 1 contains two different boron oxide units of [B5O10(OH)]6- anions and H3BO3 molecules and features 9-ring channels along the c axis in a layered structure. This barium borate is a possible deep-ultraviolet nonlinear-optical crystal for its moderate second-harmonic-generation signal and wide transparency window below 190 nm.

ABSTRACT

AIM: To establish an untransfected human corneal stromal (HCS) cell line and characterize its biocompatibility to acellular porcine corneal stroma (aPCS). METHODS: Primary culture was initiated with a pure population of HCS cells in DMEM/F12 media (pH 7.2) containing 20% fetal bovine serum and various necessary growth factors. The established cell line was characterized by growth property, chromosome analysis, tumorigenicity assay, expression of marker proteins and functional proteins. Furthermore, the biocompatibility of HCS cells with aPCS was examined through histological and immunocytochemistry analyses and with light, electron microscopies. RESULTS: HCS cells proliferated to confluence 2 weeks later in primary culture and have been subcultured to passage 140 so far. A continuous untransfected HCS cell line with a population doubling time of 41.44 hours at passage 80 has been determined. Results of chromosome analysis, morphology, combined with the results of expression of marker protein and functional proteins suggested that the cells retained HCS cell properties. Furthermore, HCS cells have no tumorigenicity, and with excellent biocompatibility to aPCS. CONCLUSION: An untransfected and non-tumorigenic HCS cell line has been established, and the cells maintained positive expression of marker proteins and functional proteins. The cell line, with excellent biocompatibility to aPCS, might be used for in vitro reconstruction of tissue-engineered HCS.
