BACKGROUND: Chronic kidney disease (CKD) is associated with common pathophysiological processes, such as inflammation and fibrosis, in both the heart and the kidney. However, the underlying molecular mechanisms that drive these processes are not yet fully understood. Therefore, this study focused on the molecular mechanism of heart and kidney injury in CKD. METHODS: We generated an microRNA (miR)-26a knockout (KO) mouse model to investigate the role of miR-26a in angiotensin (Ang)-II-induced cardiac and renal injury. We performed Ang-II modeling in wild type (WT) mice and miR-26a KO mice, with six mice in each group. In addition, Ang-II-treated AC16 cells and HK2 cells were used as in vitro models of cardiac and renal injury in the context of CKD. Histological staining, immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), and Western blotting were applied to study the regulation of miR-26a on Ang-II-induced cardiac and renal injury. Immunofluorescence reporter assays were used to detect downstream genes of miR-26a, and immunoprecipitation was employed to identify the interacting protein of LIM and senescent cell antigen-like domain 1 (LIMS1). We also used an adeno-associated virus (AAV) to supplement LIMS1 and explored the specific regulatory mechanism of miR-26a on Ang-II-induced cardiac and renal injury. Dunnett's multiple comparison and t -test were used to analyze the data. RESULTS: Compared with the control mice, miR-26a expression was significantly downregulated in both the kidney and the heart after Ang-II infusion. Our study identified LIMS1 as a novel target gene of miR-26a in both heart and kidney tissues. Downregulation of miR-26a activated the LIMS1/integrin-linked kinase (ILK) signaling pathway in the heart and kidney, which represents a common molecular mechanism underlying inflammation and fibrosis in heart and kidney tissues during CKD. Furthermore, knockout of miR-26a worsened inflammation and fibrosis in the heart and kidney by inhibiting the LIMS1/ILK signaling pathway; on the contrary, supplementation with exogenous miR-26a reversed all these changes. CONCLUSIONS Our findings suggest that miR-26a could be a promising therapeutic target for the treatment of cardiorenal injury in CKD. This is attributed to its ability to regulate the LIMS1/ILK signaling pathway, which represents a common molecular mechanism in both heart and kidney tissues.

The persistent high prevalence and poor survival outcomes of lung cancer underscore the urgent need for innovative therapeutic modalities. Here, we present a novel multifunctional delivery platform for the synergistic treatment of lung malignancies, combining in situ-triggerable photodynamic therapy (PDT) with radiotherapy. The new platform CLL was developed by loading a new reactive oxygen species (ROS)-triggerable photosensitizer, luminol-conjugated chlorin e6 (Ce6), into liposomes. CLL can be activated through the bioluminescence resonance energy transfer effect under oxidative stress, thereby producing singlet oxygen for targeted tumor treatment without external irradiation. In vitro studies showed significant cytotoxic effects of CLL in both 4T1 and A549 tumor cells. Furthermore, a PDT-radiopharmaceutical combination nanotherapy CLL-¹⁷⁷Lu was engineered by incorporating the radionuclide ¹⁷⁷Lu into CLL. CLL-¹⁷⁷Lu demonstrated synergistic antitumor effects in 4T1 and A549 tumor cells, as well as in mouse models of 4T1 breast cancer lung metastasis or A549 tumor xenografts. Mechanistically, CLL-¹⁷⁷Lu can induce singlet oxygen/ROS generation, enhance tumor cell apoptosis, and promote M1 macrophage-mediated immunotherapy. Preliminary assessments showed a favorable profile for CLL-¹⁷⁷Lu, highlighting its potential as a promising nanotherapy for cancer treatment. Additionally, CLL can serve as a versatile platform for delivering a range of therapies to achieve synergistic antitumor effects.

Objective:To explore the predictive value of the prognostic nutritional index (PNI) in concurrently infected patients with acute-on-chronic liver failure (ACLF).Methods:220 cases with ACLF diagnosed and treated at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2016 were selected. Patients were divided into an infection and non-infection group according to whether they had co-infections during the course of the disease. Clinical data differences were compared between the two groups of patients. Binary logistic regression analysis was used to screen out influencing factors related to co-infection. The receiver operating characteristic curve was used to evaluate the predictive value of PNI for ACLF co-infection. The measurement data between groups were compared using the independent sample t-test and the Mann-Whitney U rank sum test. The enumeration data were analyzed using the Fisher exact probability test or the Pearson χ2 test. The Pearson method was performed for correlation analysis. The independent risk factors for liver failure associated with co-infection were analyzed by multivariate logistic analysis. Results:There were statistically significant differences in ascites, hepatorenal syndrome, PNI score, and albumin between the infection and the non-infection group ( P ?

Objective:To investigate the perinatal outcomes and risk factors of perinatal complications in preg-nant women with hypertrophic cardiomyopathy(HCM).Methods:A retrospective analysis was carried out on clini-cal data of 100 pregnant women with HCM who delivered in Obstetrical Cardiology Intensive Care Center of Shanghai Renji Hospital between Jan.2000 and Dec.2022.Analyze the incidence of perinatal complications inclu-ding miscarriage,premature birth,small for gestational age infants,neonatal asphyxia,neonatal cardiac malforma-tions and perinatal mortality.Independent risk factors of perinatal complications in pregnant women with HCM were identified using univariate and multivariate Logistic regression.Results:①The mean age was 29.21±4.41 years old,the average gestational age upon admission is 34.46±6.43 weeks.There were 16 patients with a fam-ily history of cardiomyopathy(16％),21 cases with obstructive HCM(21％)and 79 cases of non-obstructive HCM(79％),91 cases with abnormal ECG(91％),mainly with ST-T changes(77 cases,77％).The average in-terventricular septum was 19.39±6.13mm by echocardiography.②Among the 100 pregnancies of 100 HCM pa-tients,6 cases(6％)were miscarriages,94 newborns survived(94％),including 91 cases of cesarean section(91％)and 3 cases of vaginal delivery(3％).The predominant perinatal complications were preterm delivery(39 cases,39％),small for gestational age(5 cases,5％),neonatal asphyxia(3 cases,3％)and neonatal cardiac malformation(2 cases,2％).There were no perinatal deaths.③Univariate Logistic regression analysis showed that pre pregnancy heart function ≥ Grade Ⅱ,increased left atrial diameter,and concomitant pulmonary hyperten-sion were risk factors for perinatal complications in pregnant women with HCM(OR＞1,P＜0.05).Multivariate Lo-gistic regression analysis found that pre pregnancy heart function ≥ Grade Ⅱ was an independent risk factor for predicting the occurrence of perinatal complications in pregnant women with HCM(OR 6.270,P＜0.05).Conclu-sions:HCM during pregnancy can induce poor perinatal outcome.More attention should be paid to risk assess-ment and pregnancy management.Early detection of risk factors can reduce the incidence of perinatal complica-tions.
