This study investigated the potential pathogenicity and genetic characteristics of ST314 Salmonella Kentucky(S.Ken-tucky)isolates from a broiler slaughterhouse.Antimicrobial susceptibility testing and whole-genome sequencing(WGS)were used to determine antimicrobial resistance,virulence factors,and the presence of antimicrobial resistance genes(ARGs)and mobile genetic elements(MGEs)among the isolates.The three multidrug resistant(MDR)isolates exhibited high resistance to multiple antimicrobial agents.The F4-2S strain exhibited resistance to 14 drugs across seven categories,whereas the F4T strain showed resistance to 13 drugs in the same number of categories.In contrast,the Y23 strain was resistant to nine drugs in six categories.Notably,F4-2S dem-onstrated high homology with F4T:both possessed 13 ARGs distributed across nine categories,in addition to a wide range of virulence factors,including secretion systems and effector proteins.The presence of IncR and IncX1 plasmids significantly enhanced both the antimicrobial resistance and pathogenicity of the isolates.The genome map of Y23 revealed a chromosome alongside two plasmids.The chromosome containedonly one resistance gene but several virulence factors,including the type III secretion system(T3SS),which is crucial for bacterial invasion.The plasmid pY23-1 contained eight types of 19 ARGs.Comparative analysis indicated that pY23-1 ex-hibited high homology with pZ1323SSL0055 and pSAL-045,all of which contained multiple ARGs,thus suggesting critical roles of these genes in the evolution of bacterial resistance.In conclusion,ST314 S.Kentucky demonstrated a complex mechanism of resis-tance coupled with significant pathogenic potential.The ARGs and MGEs in the plasmid contributed to the emergence and dissemina-tion of antimicrobial resistance.The multiple virulence factors present in the chromosome may be key factors driving the increasing virulence of ST314 S.Kentucky.

Objective:To investigate the effect of the embryo cryopreservation duration on pregnancy and obstetric outcome.Methods:A retrospective cohort study of 2 662 frozen-thawed embyro tranfer (FET) cycles was conducted in the Reproductive Medicine Center, Department of Obstetrics and Gynecology, Tianjin Medical University General Hospital from January 2016 to December 2020. According to embryo cryopreservation duration, the patients were divided into group A (≤1 year, n=2 115), group B (>1 years and ≤3 years, n=319), group C (>3 years and ≤6 years, n=174), and group D (>6 years, n=54). We used the propensity score matching (PSM) to match the baseline data of oocyte retrieval age of the other three groups according to group D at a ratio of 1∶3. Clinical and obstetric outcomes were compared among the four groups. Multiple logistic regression analysis was used to analyze the effect of oocyte retrieval age, embryo transfer age, the duration of embryo cryopreservation, endometrial preparation scheme, endometrial thickness, the number of transferred embryos and the number of high-quality embryos on pregnancy and live birth outcome. Results:1) Before PSM, there were significant differences in the maternal age at oocyte retrieval and embryo transfer and duration of embryo cryopreservation among the four groups(all P<0.001). 2) After PSM, the baseline characteristics of oocyte retrieval age reached a balance among the four groups. There were no statistical differences in the number of embryos transfer, the number of high-quality embryos, the transferred embryo stage, the endometrial regimen among the groups (all P>0.05). The clinical pregnancy rate [37.04% (20/54)] and the live birth rate [33.33% (18/54)] in group D were lower than those in group A [51.57% (82/159), 40.88% (65/159)], group B [50.00% (65/130), 40.77% (53/130)] and group C [49.59% (61/123), 39.02% (48/123)], but the difference was not statistically significant between the four groups ( P=0.310, P=0.781). There were no statistical differences among the four groups in the ratio of male to female newborns, gestational age, birth weight, preterm delivery rate, low birth weight rate, macrosomia rate, birth defects, and premature repture of membranes (all P>0.05). 3) Multiple logistic regression analysis showed that the number of high-quality embryos transferred affected the clinical pregnancy outcome (before PSM, OR=2.614, 95% CI: 2.168-3.151, P<0.001; after PSM, OR=1.984, 95% CI: 1.406-2.800, P<0.001) and live birth (before PSM, OR=2.708, 95% CI: 2.198-3.336, P<0.001; after PSM, OR=2.122, 95% CI: 1.474-3.053, P<0.001). The duration of embryo cryopreservation does not affect the clinical outcome and live birth (all P>0.05). Conclusion:The duration of embryo cryopreservation does not affect the clinical outcome and live birth, but large sample data are still needed to support this conclusion in the future.

Fibrosis, the pathological scarring of vital organs, is a severe and often irreversible condition that leads to progressive organ dysfunction. It is particularly pronounced in organs like the liver, kidneys, lungs, and heart. Despite its clinical significance, the full understanding of its etiology and complex pathogenesis remains incomplete, posing substantial challenges to diagnosing, treating, and preventing the progression of fibrosis. Among the various molecular players involved, platelet-derived growth factor-C (PDGF-C) has emerged as a crucial factor in fibrotic diseases, contributing to the pathological transformation of tissues in several key organs. PDGF-C is a member of the PDGFs family of growth factors and is synthesized and secreted by various cell types, including fibroblasts, smooth muscle cells, and endothelial cells. It acts through both autocrine and paracrine mechanisms, exerting its biological effects by binding to and activating the PDGF receptors (PDGFRs), specifically PDGFRα and PDGFRβ. This binding triggers multiple intracellular signaling pathways, such as JAK/STAT, PI3K/AKT and Ras-MAPK pathways. which are integral to the regulation of cell proliferation, survival, migration, and fibrosis. Notably, PDGF-C has been shown to promote the proliferation and migration of fibroblasts, key effector cells in the fibrotic process, thus accelerating the accumulation of extracellular matrix components and the formation of fibrotic tissue. Numerous studies have documented an upregulation of PDGF-C expression in various fibrotic diseases, suggesting its significant role in the initiation and progression of fibrosis. For instance, in liver fibrosis, PDGF-C stimulates hepatic stellate cell activation, contributing to the excessive deposition of collagen and other extracellular matrix proteins. Similarly, in pulmonary fibrosis, PDGF-C enhances the migration of fibroblasts into the damaged areas of lungs, thereby worsening the pathological process. Such findings highlight the pivotal role of PDGF-C in fibrotic diseases and underscore its potential as a therapeutic target for these conditions. Given its central role in the pathogenesis of fibrosis, PDGF-C has become an attractive target for therapeutic intervention. Several studies have focused on developing inhibitors that block the PDGF-C/PDGFR signaling pathway. These inhibitors aim to reduce fibroblast activation, prevent the excessive accumulation of extracellular matrix components, and halt the progression of fibrosis. Preclinical studies have demonstrated the efficacy of such inhibitors in animal models of liver, kidney, and lung fibrosis, with promising results in reducing fibrotic lesions and improving organ function. Furthermore, several clinical inhibitors, such as Olaratumab and Seralutinib, are ongoing to assess the safety and efficacy of these inhibitors in human patients, offering hope for novel therapeutic options in the treatment of fibrotic diseases. In conclusion, PDGF-C plays a critical role in the development and progression of fibrosis in vital organs. Its ability to regulate fibroblast activity and influence key signaling pathways makes it a promising target for therapeutic strategies aiming at combating fibrosis. Ongoing research into the regulation of PDGF-C expression and the development of PDGF-C/PDGFR inhibitors holds the potential to offer new insights and approaches for the diagnosis, treatment, and prevention of fibrotic diseases. Ultimately, these efforts may lead to the development of more effective and targeted therapies that can mitigate the impact of fibrosis and improve patient outcomes.
