Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

ObjectiveTo investigate the effect of transplantation of bone marrow mesenchymal stem cells (BMSCs) co-cultured with bone marrow-derived M2 macrophages (M2-BMDMs), named as BMSCM2, on a rat model of liver cirrhosis induced by carbon tetrachloride (CCl4)/2-acetaminofluorene (2-AAF). MethodsRat BMDMs were isolated and polarized into M2 phenotype, and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSCM2. The rats were given subcutaneous injection of CCl4 for 6 weeks to establish a model of liver cirrhosis, and then they were randomly divided into model group (M group), BMSC group, and BMSCM2 group, with 6 rats in each group. A normal group (N group) with 6 rats was also established. Since week 7, the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl4. Samples were collected at the end of week 10 to observe liver function, liver histopathology, and hydroxyproline (Hyp) content in liver tissue, as well as changes in the markers for hepatic stellate cells, hepatic progenitor cells, cholangiocytes, and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group, the M group had significant increases in the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in ALT and AST (P<0.01), and the BMSCM2 group had significantly better activities than the BMSC group (P<0.05). Compared with the N group, the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin (α-SMA) in the liver (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in Hyp content and the expression of α-SMA (P<0.05), and the BMSCM2 group had a significantly lower level of α-SMA than the BMSC group (P<0.01). Compared with the N group, the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 (P<0.01) and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in the mRNA expression levels of EpCam, Sox9, CK7, and CK19 (P<0.05) and significant increases in the mRNA expression levels of HNF-4α and Alb (P<0.05), and compared with the BMSC group, the BMSCM2 group had significant reductions in the mRNA expression levels of EpCam and CK19 (P<0.05) and significant increase in the expression level of HNF-4α (P<0.05). ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl4/2-AAF-induced liver cirrhosis in rats, which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.

Solute carriers (SLCs) constitute the largest superfamily of membrane transporter proteins. These transporters, present in various SLC families, play a vital role in energy metabolism by facilitating the transport of diverse substances, including glucose, fatty acids, amino acids, nucleotides, and ions. They actively participate in the regulation of glucose metabolism at various steps, such as glucose uptake (e.g., SLC2A4/GLUT4), glucose reabsorption (e.g., SLC5A2/SGLT2), thermogenesis (e.g., SLC25A7/UCP-1), and ATP production (e.g., SLC25A4/ANT1 and SLC25A5/ANT2). The activities of these transporters contribute to the pathogenesis of type 2 diabetes mellitus (T2DM). Notably, SLC5A2 has emerged as a valid drug target for T2DM due to its role in renal glucose reabsorption, leading to groundbreaking advancements in diabetes drug discovery. Alongside SLC5A2, multiple families of SLC transporters involved in the regulation of glucose homeostasis hold potential applications for T2DM therapy. SLCs also impact drug metabolism of diabetic medicines through gene polymorphisms, such as rosiglitazone (SLCO1B1/OATP1B1) and metformin (SLC22A1-3/OCT1-3 and SLC47A1, 2/MATE1, 2). By consolidating insights into the biological activities and clinical relevance of SLC transporters in T2DM, this review offers a comprehensive update on their roles in controlling glucose metabolism as potential drug targets.

Objective To isolate endophytic fungi from Angelica sinensis and evaluate the bioactivity of their secondary metabolites.Methods Angelica sinensis and rhizosphere soil were utilized as materials.The tissue homogenization method was employed with six diverse culture media to isolate endophytic fungi.The antibacterial activity of secondary metabolites was gauged using a 96-well plate assay,while UV spectrophotometry was used to evaluate the inhibitory activity of four enzymes.Results A total of 153 fungal strains were isolated and purified from Angelica sinensis roots,stems,leaves,and soil.The samples exhibited specific inhibitory activities against adenosine deaminase(ADA),β-lactamase,xanthine oxidase(XO),and tyrosinase(TYR),with rates of 45.83%,52.78%,51.39%and 55.56%,respectively.Furthermore,1.39%of the samples displayed wide-ranging inhibitory effects against four indicator bacteria.Strain 6B also showcased the lowest inhibitory concentration values of 62.5 and 7.81 μg/mL against Escherichia coli ATCC25922 and ATCC35218,respectively,signifying its potential research significance.Conclusion Angelica sinensis has abundant endophytic fungal resources and is a good source for discovering active compounds,demonstrating certain research value.

Objective:To investigate the clinical efficacy of Cyclosporine A(CsA)in patients with unexplained repeated implantation failure(URIF),and to analyze the changes of peripheral blood lymphocyte subsets after CsA treatment.Methods:105 patients with URIF who underwent frozen-thawed embryo transfer(FET)in the De-partment of Reproductive Medicine in The Second Affiliated Hospital of Kunming Medical University from Septem-ber 30,2021 to March 1,2022 were selected.After informed consent,the patients were divided into CsA group(n=52)and control group(n=53)according to whether they received CsA treatment or not.Pregnancy outcomes and changes in lymphocyte subset were compared between the two groups.Results:The embryo implantation rate and clinical pregnancy rate in CsA group were higher than those in the control group,the difference was statisti-cally significant(48.91%vs.32.56%,P=0.027;53.85%vs.32.08%,P=0.024).The CsA group had a lower ear-ly abortion rate than the control group(10.71%vs.23.53%),but the difference was not statistically significant(P=0.25).The percentage of CD3-CD16+CD56+in CsA group was significantly decreased after treatment[(16.15±5.37)%vs.(18.23±7.10)%,P=0.012],it was also lower than that in the control group[(16.15±5.37)%vs.(18.67±5.16)%,P=0.018].Conclusions:CsA treatment can significantly improve the clinical preg-nancy rate and embryo implantation rate of frozen-thawed embryo transfer in patients with URIF,which may be a-chieved by promoting the distribution of peripheral blood lymphocytes to the direction of embryo implantation,es-pecially by down-regulating the percentage of CD3-CD16+CD56+.CsA has a certain application prospect in the field of assisted reproduction.
