OBJECTIVE: To study the protective efffects of Chailing Guiqi Decoction (CLGQD) combined with lumbrukinase on renal function in rats with adriamycin nephropathy. METHODS: Thirty-six SD rats were randomly divided into four groups: normal control group, untreated group, simvastatin-treated group and CLGQD -treated group. Adriamycin nephropathy was induced by intravenous injection with 5 mg/kg adriamycin. After seven-day treatment, quantitative measurement of 24-h urine protein was determined with trichloroacetic acid, and serum total protein (TP), albumin (Alb), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine (Cr) and blood urea nitrogen (BUN) were assessed using automatic biochemistry analyzer. The pathomorphological changes of renal tissues were observed with light and electron microscopes. RESULTS: In the untreated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly higher than those in the normal control group (P<0.05 or P<0.01), while the serum TP, Alb, HDL were significantly lower than those in the normal control group (P<0.01). In the CLGQD-treated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly lower as compared with those in the untreated group (P<0.05 or P<0.01), while the serum TP, Alb and HDL were significantly higher as compared with those in the untreated group (P<0.05 or P<0.01). The pathomorphological findings of the renal tissues under the light microscope in the untreated group showed focal segmental glomerulosclerosis in a few of glomerulus, degenerated and swelled proximal tubular epithelial cells, proteins in cast formation in some renal tubules and scattered fibrosis in interstitial tissues of the kidney, while the electron microscope images showed the fusion of foot processes in glomerular epithelial cells. The pathomorphological changes in the CLGQD-treated group were slighter than those in the untreated group. CONCLUSION: CLGQD combined with lumbrukinase can reduce proteinuria, regulate lipid metabolism, protect renal function, and delay progressive renal damage in rats.

The research on human hepatobiliary development and disorders has been constrained by minimal access to human fetal tissue, and low accuracy of animal models. To overcome this problem, we have established a system for the differentiation of human pluripotent stem cells (hPSCs) into functional hepatobiliary organoids (HBOs). We have previously reported that our 45-d approach closely mimics key stages of hepatobiliary development, starting with the differentiation of hiPSC into endoderm and a small part of mesoderm, and subsequently into hepatoblast-like cells, followed by the parallel generation of hepatocyte-like cells and cholangiocyte-like cells, formation of immature HBO expressing early hepatic and biliary markers, and mature HBO displaying hepatobiliary functionality. In this study, we present an updated version of our previous protocol, which only needs 35 days to achieve maturation in vitro. Furthermore, a hepatobiliary culture medium is developed to functionally maintain the HBOs for more than 1.5 months. The capacity of this approach for producing large amounts of functional HBOs and enabling long-term culture in vitro holds promise for applications on developmental research, disease modeling, as well as screening of therapeutic agents.

Derived from embryonic stem cells, induced pluripotent stem cells, or adult stem cells, liver organoids not only mimic the tissue structure, gene expression patterns, and genetic characteristics of in vivo liver but also demonstrate significant potential in simulating liver diseases, drug screening, precision medicine, and regenerative medicine. This technology is particularly valuable in modeling various conditions such as malignant liver tumors, liver fibrosis, cirrhosis, viral hepatitis, and a range of genetic and metabolic liver diseases. However, challenges remain in enhancing the derivation and proliferation efficiency of organoids, constructing immune microenvironments, developing functional vascular networks, and achieving standardization and automation in the organoid preparation process. Looking forward, with continued technological advancements and innovations, these issues are expected to be resolved, paving the way for liver organoids to play a more substantial role in clinical and research applications, ultimately contributing significantly to public health. This review comprehensively explores the development and extensive applications of liver organoid technology in the field of biomedical science. The aim is to inform subsequent research.
