Comparison of risk factors between lean and non-lean MASLD in individuals with type 2 diabetes: a multicenter study.

OBJECTIVE: A multi-center study in patients with type 2 diabetes mellitus (T2DM) was performed to assess the differences of liver steatosis and fibrosis between lean and non-lean individuals. METHODS: Patients with T2DM from16 centers were recruited and underwent transient elastography examination for diagnosis of liver steatosis and fibrosis. Clinical information including diabetes status, serum lipids profiles, and inflammatory markers were collected. Potential risk factors of liver steatosis and fibrosis in lean (BMI＜23 kg/m2) and non-lean (BMI≥23 kg/m2) groups were analyzed. RESULTS: A total of 1762 patients were included. The prevalence of liver steatosis and fibrosis in lean group were 44.7% and 23.4%. Prevalence of hypertension and cardiovascular disease were higher in lean patients compared to non-lean group. Lean patients with liver steatosis or fibrosis were older, had longer diabetes duration, lower levels of HOMA-IR and serum lipids. Body mass index (BMI), visceral fat area (VFA) and triglyceride were among the most significant correlators of liver steatosis for both non-lean and lean patients. However, lipid profiles were different between two groups. Besides, insulin resistance, BMI and lipid levels were not observed to be associated with fibrosis in lean group. CONCLUSION: Liver steatosis and fibrosis in lean patients with T2DM were less associated with insulin resistance. Risk factors of liver steatosis were different between lean and non-lean patients, indicating the necessity of risk stratification and tailored management strategies.

The role of left atrium posterior wall isolation in patients undergoing catheter ablation for atrial fibrillation.

The posterior left atrium (LAPW) is an important substrate for initiation and maintenance of atrial fibrillation (AF). While it has been proposed as a potential target for preventing recurrence of atrial tachyarrhythmias, it remains unclear whether electrical silence of LAPW offers additional benefits over pulmonary vein isolation (PVI) alone. We conducted a systematic review of PubMed, Medline, Embase, and Cochrane databases and identified 21 eligible studies, encompassing 1514 patients assigned to PVI + posterior wall isolation (PWI) group and 1629 patients assigned to PVI group. Over a median follow-up of 12 months, adjunctive PWI significantly improved the atrial tachyarrhythmia-free survival by 14 % in comparison to PVI alone [relative risk (RR): 1.14, 95 % confidence interval (CI): 1.04 to 1.25, p = 0.004]. This improvement was mainly attributed to a pronounced benefit for patients with persistent AF. In addition, patients undergoing PVI + PWI had a longer procedure time [weighted mean difference (WMD): 23.85, 95 % CI: 12.68 to 35.01, p < 0.001], ablation time (WMD: 9.27, 95 % CI: 5.19 to 13.54, p < 0.001), and a nearly negligible increase in fluoroscopic exposure (WMD: 2.69, 95 % CI: -0.23 to 5.62, p = 0.071). There was no increased risk of procedure-related complications between these approaches (RR: 1.06, 95 % CI: 0.71 to 1.57, p = 0.787). Compared with PVI alone, PWI adjunctive to PVI exhibited a higher procedure success of sinus rhythm maintenance in persistent AF during an index catheter ablation. Meanwhile, elongated procedure time and ablation time did not compromise the safety of extensive ablation strategy with additional PWI.

Synchronous End-to-End Vehicle Pedestrian Detection Algorithm Based on Improved YOLOv8 in Complex Scenarios.

In modern urban traffic, vehicles and pedestrians are fundamental elements in the study of traffic dynamics. Vehicle and pedestrian detection have significant practical value in fields like autonomous driving, traffic management, and public security. However, traditional detection methods struggle in complex environments due to challenges such as varying scales, target occlusion, and high computational costs, leading to lower detection accuracy and slower performance. To address these challenges, this paper proposes an improved vehicle and pedestrian detection algorithm based on YOLOv8, with the aim of enhancing detection in complex traffic scenes. The motivation behind our design is twofold: first, to address the limitations of traditional methods in handling targets of different scales and severe occlusions, and second, to improve the efficiency and accuracy of real-time detection. The new generation of dense pedestrian detection technology requires higher accuracy, less computing overhead, faster detection speed, and more convenient deployment. Based on the above background, this paper proposes a synchronous end-to-end vehicle pedestrian detection algorithm based on improved YOLOv8, aiming to solve the detection problem in complex scenes. First of all, we have improved YOLOv8 by designing a deformable convolutional improved backbone network and attention mechanism, optimized the network structure, and improved the detection accuracy and speed. Secondly, we introduced an end-to-end target search algorithm to make the algorithm more stable and accurate in vehicle and pedestrian detection. The experimental results show that, using the algorithm designed in this paper, our model achieves an 11.76% increase in precision and a 6.27% boost in mAP. In addition, the model maintains a real-time detection speed of 41.46 FPS, ensuring robust performance even in complex scenarios. These optimizations significantly enhance both the efficiency and robustness of vehicle and pedestrian detection, particularly in crowded urban environments. We further apply our improved YOLOv8 model for real-time detection in intelligent transportation systems and achieve exceptional performance with a mAP of 95.23%, outperforming state-of-the-art models like YOLOv5, YOLOv7, and Faster R-CNN.

Application of 11/13Fr suctioning ureteral access sheath and 8.55Fr single-use digital flexible ureteroscope in one-stage flexible ureteroscopic lithotripsy: an initial experience of 900 cases.

OBJECTIVES: To report our initial experience of one-stage flexible ureteroscopic lithotripsy(FURL) with 11/13Fr suctioning ureteral access sheath(UAS) and 8.55Fr single-use digital flexible ureteroscope(SDFU) in upper ureteral or renal calculi. MATERIALS AND METHODS: We retrospectively collected the clinical data of 900 adult patients with upper ureteral or renal calculi treated by FURL with 11/13Fr suctioning UAS and 8.55Fr SDFU from January 2022 to April 2024. Demographics, peri- and postoperative outcomes were assessed. RESULTS: In all, 40 of 940 cases(4.26%) failed to introduce UAS and required second-stage FURL because of ureterostenosis and were excluded. Mean stones size of the remaining 900 eligible cases was 1.68 ± 0.58 cm in greatest diameter. There were 228 cases of upper ureteral stone, 456 cases of renal stone and 216 cases of concomitant ureteral and renal calculi. The mean operation time was 52.20 ± 20.21 min and the postoperative hospital stay was 2.87 ± 1.37 days. The stone-free rate of 1 month postoperatively was 89.56% and only 2.44% of patients with residue underwent additional reoperation. The rate of postoperative fever, postoperative pain needing analgesic and slight ureteral mucosal injury were 5.11%, 8.22% and 7.78%, respectively. None of patient suffered from severe complications, such as sepsis or ureteral perforation. CONCLUSION: It's practical and suitable for the vast majority of adult patients to undergo FURL in single session with 11/13Fr suctioning UAS without preoperative stenting. FURL with 11/13Fr suctioning UAS and 8.55Fr SDFU is feasible, reliable, safe, and efficient in the management of renal stone and upper ureteral stone.

Complete genome sequence of a novel Pseudomonas sp. IT1137 isolated from Antarctic intertidal sediment showing potential for alkane degradation at low temperatures.

Pseudomonas species are known for their diverse metabolic abilities and broad ecological distribution. They are fundamental components of bacterial communities and perform essential ecological functions in the environment. A psychrotrophic Pseudomonas sp. IT1137 was isolated from intertidal sediment in the coastal region of the Fildes Peninsula, King George Island, Antarctica. The strain contained a circular chromosome of 5,346,697 bp with a G + C content of 61.66 mol% and one plasmid of 4481 bp with a G + C content of 64.61 mol%. A total of 4848 protein-coding genes, 65 tRNA genes and 15 rRNA genes were obtained. Genome sequence analysis revealed that strain IT1137 not only is a potentially novel species of the genus Pseudomonas but also harbors functional genes related to nitrogen, sulfur and phosphorus cycling. In addition, genes involved in alkane degradation, ectoine synthesis and cyclic lipopeptide (CLP) production were detected in the bacterial genome. The results indicate the potential of the strain Pseudomonas sp. IT1137 for biotechnological applications such as bioremediation and secondary metabolite production and are helpful for understanding bacterial adaptability and ecological function in cold coastal environments.

Assessing the Presence of Phosphoinositides on Autophagosomal Membrane in Yeast by Live Cell Imaging.

The formation of autophagosomes mediating the sequestration of cytoplasmic materials is the central step of autophagy. Several phosphoinositides, which are signaling molecules on the membrane, are involved in autophagy. However, it is not always clear whether these phosphoinositides act directly at the site of autophagosome formation, or indirectly via the regulation of other steps or pathways. To address this question, we used a set of phosphoinositide probes to systematically examine their potential presence on autophagosomal membranes in yeast (Saccharomyces cerevisiae). We verified the specificity of these probes using mutant cells deficient in the production of the corresponding phosphoinositides. We then examined starved yeast cells co-expressing a phosphoinositide probe together with an autophagosomal membrane marker, 2Katushka2S-Atg8. Our data revealed that PtdIns(4,5)P2 and PtdIns(3,5)P2 were mainly present on the plasma membrane and vacuolar membrane, respectively. We observed only occasional co-localization between the PtdIns(4)P probe and Atg8, some of which may represent the transient passage of a PtdIns(4)P-containing structure near the autophagosomal membrane. In contrast, substantial colocalization of the PtdIns(3)P probe with Atg8 was observed. Taken together, our data indicate that only PtdIns(3)P is present in a substantial amount on the autophagosomal membrane. For other phosphoinositides involved in autophagy, either their presence on the autophagosomal membrane is very transient, or they act on other cellular membranes to regulate autophagy.

Pseudomonas paeninsulae sp. nov. and Pseudomonas svalbardensis sp. nov., isolated from Antarctic intertidal sediment and Arctic soil, respectively.

Two Gram-stain-negative, aerobic, rod-shaped, non-endospore-forming and motile bacterial strains, designated IT1137T and S025T, were isolated from an intertidal sediment sample collected from the Fildes Peninsula (King George Island, Maritime Antarctica) and a soil sample under red snow in the Ny-Ålesund region (Svalbard, High Arctic), respectively. The 16S rRNA gene sequence similarity values grouped them in the genus Pseudomonas. The two strains were characterized phenotypically using API 20E, API 20NE, API ZYM and Biolog GENIII tests and chemotaxonomically by their fatty acid contents, polar lipids and respiratory quinones. Multilocus sequence analysis (concatenated 16S rRNA, gyrB, rpoB and rpoD sequences), together with genome comparisons by average nucleotide identity and digital DNA-DNA hybridization, were performed. The results showed that the similarity values of the two isolates with the type strains of related Pseudomonas species were below the recognized thresholds for species definition. Based on polyphasic taxonomy analysis, it can be concluded that strains IT1137T and S025T represent two novel species of the genus Pseudomonas, for which the names Pseudomonas paeninsulae sp. nov. (type strain IT1137T=PMCC 100533T=CCTCC AB 2023226T=JCM 36637T) and Pseudomonas svalbardensis sp. nov. (type strain S025T=PMCC 200367T= CCTCC AB 2023225T=JCM 36638T) are proposed.

VlMYB4 and VlCDF3 co-targeted the VlLOG11 promoter to regulate fruit setting in grape (Vitis vinifera L).

KEY MESSAGE: The VlLOG11 mediates the cytokinin signaling pathway to regulate grape fruit setting. Fruit set, as an accepted agronomic trait, is inextricably linked with fruit quality and yield. Previous studies have demonstrated that exogenous treatment with the synthetic cytokinin analog, forchlorfenuron (CPPU), significantly enhances fruit set. In this study, a significant reduction in endogenous cytokinins was found by measuring the content of cytokinins in young grape berries after CPPU treatment. LONELY GUYs (VlLOGs), a key cytokinin-activating enzyme working in the biosynthesis pathway of cytokinins, exhibited differential expression. Some differentially expressed VlLOGs genes were presented by RNA seq data and their functions and regulation patterns were further investigated. The results showed that VlLOG11 was differentially expressed in young grape berries after CPPU treatment. Overexpression of VlLOG11 in tomato increases the amount of fruit set, and upregulated the expression of genes associated with cytokinin signaling including SlHK4, SlHK5, SlHP3, SlHP4, SlPHP1, SlPHP2. VlMYB4 and VlCDF3 could regulate the expression of VlLOG11 by directly binding to its promoter in young grape berries during fruit set. These results strongly demonstrated that VlMYB4/VlCDF3-VlLOG11 regulatory module plays a key role in the process of fruit setting in grape. This provided a basis for the molecular mechanism of VlLOG11-mediated cytokinin biosynthesis in young grape fruit set.

A cross-sectional analysis of the relationship between the non-high density to high density lipoprotein cholesterol ratio (NHHR) and kidney stone risk in American adults.

BACKGROUND: Recent interest in the Non-High Density to High Density Lipoprotein Cholesterol ratio (NHHR) has emerged due to its potential role in metabolic disorders. However, the connection between NHHR and the development of kidney stones still lacks clarity. The primary goal of this research is to explore how NHHR correlates with kidney stone incidence. METHODS: An analysis was conducted on the data collected by the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2018, focusing on adults over 20 years diagnosed with kidney stones and those with available NHHR values. Employing weighted logistic regression and Restricted Cubic Spline (RCS) models, NHHR levels' correlation with kidney stone risk was examined. Extensive subgroup analyses were conducted for enhanced reliability of the findings. RESULTS: The findings indicate a heightened kidney stone risk for those at the highest NHHR levels relative to those at the lowest (reference group). A notable non-linear correlation of NHHR with kidney stone incidence has been observed, with a significant P-value (< 0.001), consistent across various subgroups. CONCLUSION: A clear link exists between high NHHR levels and increased kidney stone risk in the American adult population. This study highlights NHHR's significance as a potential indicator in kidney stone formation.

Association between kidney stones and life's essential 8: a population-based study.

BACKGROUND: Kidney stones exhibit a robust correlation with cardiovascular disease (CVD). The objective of this research is to investigate the correlation between kidney stones and Life's Essential 8 (LE8), a newly updated assessment of cardiovascular health (CVH), among adults in the United States. METHODS: In this study, which analyzed data from the 2007-2018 National Health and Nutrition Examination Survey, we employed LE8 scores (ranging from 0 to 100) as the independent variable, classifying them into low, moderate, and high CVH categories. The research examined the relationship between LE8 scores and kidney stones by using multivariate logistic regression and restricted cubic spline models, with kidney stones as the dependent variable. RESULTS: Out of the 14,117 participants in this research, the weighted mean LE8 score was 69.70 ± 0.27. After accounting for confounding factors, there was an inverse association between higher LE8 scores and the likelihood of developing kidney stones (OR of 0.81 per 10-point increase, with a 95% confidence interval of 0.77-0.85), demonstrating a non-linear dose-response pattern. Similar patterns were observed for health behaviors, health factor scores, and kidney stones. Stratified analyses demonstrated a stable negative correlation between LE8 scores and kidney stones across different subgroups. CONCLUSION: LE8 and its subscale scores exhibited a robust and inverse correlation with the occurrence of kidney stones. Encouraging adherence to optimal CVH levels has the potential to serve as an effective strategy in preventing and minimizing the occurrence of kidney stones.

Resting state functional connectome in breast cancer patients with fear of cancer recurrence.

This study aimed to investigate network-level brain functional changes in breast cancer patients and their relationship with fear of cancer recurrence (FCR). Resting-state functional MRI was collected from 43 patients with breast cancer and 40 healthy controls (HCs). Graph theory analyses, whole-brain voxel-wise functional connectivity strength (FCS) analyses and seed-based functional connectivity (FC) analyses were performed to identify connection alterations in breast cancer patients. Correlations between brain functional connections (i.e. FCS and FC) and FCR level were assessed to further reveal the neural mechanisms of FCR in breast cancer patients. Graph theory analyses indicated a decreased clustering coefficient in breast cancer patients compared to HCs (P = 0.04). Patients with breast cancer exhibited significantly higher FCS in both higher-order function networks (frontoparietal, default mode, and dorsal attention systems) and primary somatomotor networks. Among the hyperconnected regions in breast cancer, the left inferior frontal operculum demonstrated a significant positive correlation with FCR. Our findings suggest that breast cancer patients exhibit less segregation of brain function, and the left inferior frontal operculum is a key region associated with FCR. This study offers insights into the neural mechanisms of FCR in breast cancer patients at the level of brain connectome.

Complete genome sequence of the novel Antarctic Oceanisphaera sp. IT1-181 that carried five plasmids.

Bacteria of the genus Oceanisphaera in the class Gammaproteobacteria are widely distributed in marine environments. Oceanisphaera sp. IT1-181 was isolated from intertidal sediment in the coastal region of the Chinese Great Wall Station on the Fildes Peninsula, King George Island, Antarctica. Here, we sequenced the complete genome of strain IT1-181, which contained a single chromosome of 3,572,184 bp (G + C content of 49.89 mol%) with five plasmids. A total of 3229 protein-coding genes, 88 tRNA genes, and 25 rRNA genes were obtained. Genome sequence analysis revealed that strain IT1-181 was not only a potentially novel species of the genus Oceanisphaera, but also harbored genes involved in biosynthesizing ectoine as well as poly-ß-hydroxybutyric acid (PHB). In addition, genes of a complete type I-E CRISPR-Cas system were found in the bacterium. The results indicate the potential of strain Oceanisphaera sp. IT1-181 in biotechnology and are helpful for us understanding its ecological roles in the changing Antarctic intertidal zone environment.

Comparative Efficacy of Drug Interventions on NAFLD Over 24 Weeks: A Traditional and Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND AND AIMS: Nonalcoholic fatty liver disease (NAFLD), currently referred to as metabolic dysfunction-associated steatotic liver disease (MASLD), affects approximately 38% of the world's population, yet no pharmacological therapies have been approved for treatment. We conducted a traditional and network meta-analysis to comprehensively assess the effectiveness of drug regimens on NAFLD, and continued to use the old terminology for consistency. METHODS: Randomized, placebo-controlled trials (RCTs) investigating drug therapy in an adult population diagnosed with NAFLD with or without diabetes mellitus were included. We assessed the quality of RCTs via the Risk of Bias 2 (ROB 2) tool. When I2 < 50%, we chose a random-effects model, otherwise a fixed-effects model was selected. A random effects model was applied in the network meta-analysis. The odds ratio (OR), weighted mean difference (WMD) or standard mean difference (SMD) with 95% confidence interval (CI) were used for outcome evaluation. The primary endpoint was the resolution of nonalcoholic steatohepatitis (NASH) without the worsening of liver fibrosis. Other endpoints included histological findings and metabolic changes. The PROSPERO Registration ID was CRD42023404309. RESULTS: Thiazolidinediones (TZDs), vitamin E plus pioglitazone, glucagon-like peptide-1 (GLP-1) receptor agonists and fibroblast growth factor-21 (FGF-21) analogue had a higher surface under the cumulative ranking curve (SUCRA = 76.6, 73.0, 72.0 and 71.6) regarding NASH resolution. Improvement of liver fibrosis stage (≥ 1) was observed with obeticholic acid 25 mg/day (OR 2.01, 95% CI 1.35-2.98), lanifibranor 1200 mg/day (OR 2.39, 95% CI 1.19-4.82) and silymarin (OR 4.54, 95% CI 1.18-17.43) in traditional meta-analysis. CONCLUSIONS: The results of the comprehensive analysis suggested hypoglycemic drug therapy as an effective intervention for NAFLD, with or without diabetes mellitus. A prioritized selection of TZDs, vitamin E plus pioglitazone, GLP-1 receptor agonists and FGF-21 analogue may be considered for NASH resolution. Obeticholic acid, lanifibranor and silymarin could be considered for the improvement of liver fibrosis. Each medication was relatively safe compared with placebo.

Benefit finding in chronic kidney disease patients receiving hemodialysis: a cross-sectional study.

BACKGROUND AND OBJECTIVES: The psychological problems of hemodialysis (HD) patients are prominent, and benefit finding (BF) have been proven beneficial to physical and mental health, fewer researchers explored BF in HD patients. The aim of this study was to investigate the current status of BF in patients with chronic kidney disease and to analyze the factors influencing it in order to provide a reference for subsequent interventions. METHODS: A cross-sectional study was done on 246 HD patients by convenience sampling in the hemodialysis center of a 3 A hospital in Shanghai from March to September 2019. The measures include General Information Questionnaire, Benefit Finding Scale, Perceived Social Support Scale, General Self-efficacy Scale, and Simplified Coping Style scale. RESULTS: The median (interquartile range, IQR) score of BF was 66 (IQR = 19) and it was lower compared with other chronic diseases. Significant differences in BF scores were found between different age groups, HD duration categories, and understanding degrees of HD. Taking BF as the dependent variable, the results of multiple linear regression analysis showed that age, duration of HD, family support, other support, positive coping, and self-efficacy entered the regression equation to explain 43.8% of the total variation. Social support played an indirect effect in the relationship between positive coping and BF, accounting for 54.1% of the total effect. CONCLUSION: The BF of HD patients is worrisome and affected by many factors. Medical staff could pay attention to the positive psychology of HD patients, and construct individualized interventions according to the influencing factors to improve their BF level and achieve physical and mental health.

Development of a prognostic signature for immune-associated genes in bladder cancer and exploring potential drug findings.

BACKGROUND: Bladder cancer, predominantly affecting men, is a prevalent malignancy of the urinary system. Although platinum-based chemotherapy has demonstrated certain enhancements in overall survival when compared to surgery alone, the efficacy of treatments is impeded by the unfavorable side effects of conventional chemotherapy medications. Nonetheless, immunotherapy exhibits potential in the treatment of bladder cancer. METHODS: To create an immune-associated prognostic signature for bladder cancer, bioinformatics analyses were performed utilizing The Cancer Genome Atlas (TCGA) database in this study. By identifying differential gene expressions between the high-risk and low-risk groups, a potential therapeutic drug was predicted using the Connectivity Map database. Subsequently, the impact of this drug on the growth of T24 cells was validated through MTT assay and 3D cell culture techniques. RESULTS: The signature included 1 immune-associated LncRNA (NR2F1-AS1) and 16 immune-associated mRNAs (DEFB133, RBP7, PDGFRA, CGB3, PDGFD, SCG2, ADCYAP1R1, OPRL1, PGR, PSMD1, TANK, PRDX1, ADIPOR2, S100A8, AHNAK, EGFR). Based on the assessment of risk scores, the patients were classified into cohorts of low-risk and high-risk individuals. The cohort with low risk demonstrated a considerably higher likelihood of survival in comparison to the group with high risk. Furthermore, variations in immune infiltration were noted among the two categories. Cephaeline, a possible medication, was discovered by analyzing variations in gene expression. It exhibited promise in suppressing the viability and growth of T24 bladder cancer cells. CONCLUSION: The novel predictive pattern allows for efficient categorization of patients with bladder cancer, enabling focused and rigorous treatment for those expected to have a worse prognosis. The discovery of a possible curative medication establishes a basis for forthcoming immunotherapy trials in bladder cancer.

Solute carrier family 2 member 12 intervenes in uric acid-induced renal tubular cell injury / 中国组织工程研究

BACKGROUND:In recent years,the incidence of hyperuricemia caused by purine metabolism disorders has been increasing,which can induce inflammatory responses and lead to renal injury. OBJECTIVE:To explore the role and mechanism of solute carrier family 2 member 12(SLC2A12)in hyperuricemia-related renal injury. METHODS:Renal tubular cells(HK2 cells)were divided into five groups:HK2 group,HK2+uric acid group,HK2+uric acid+NC group,HK2+uric acid+siSLC2A12 group,and HK2+uric acid+siSLC2A12+MK-2206 group.HK2 cells were treated with uric acid and transfected with siRNA SLC2A12,followed by MK-2206 treatment to inhibit AKT expression.Cell proliferation was detected by CCK-8 assay.Apoptosis was detected by TUNEL assay.qRT-PCR and western blot assay were used to detect fibrogenic factors as well as activation of the AKT/FOXO3a pathway.The concentrations of inflammatory cytokines were measured by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:(1)Uric acid treatment inhibited cell proliferation and promoted cell apoptosis in the HK2+uric acid group compared with the HK2 group.The proliferative ability of cells in the HK2+uric acid+siSLC2A12 group was further decreased and apoptotic cells were further increased compared with the HK2 group.Compared with the HK2+uric acid+siSLC2A12 group,the HK2+uric acid+siSLC2A12+MK-2206 group showed an increase in cell proliferation and a decrease in apoptotic cells.(2)Compared with the HK2 group,the connective tissue growth factor(CTGF),α-smooth muscle actin(α-SMA)and transforming growth factor beta(TGF-β)expressions increased in the HK2+uric acid group;CTGF,α-SMA and TGF-β expression further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,the CTGF,α-SMA and TGF-β expressions decreased.(3)Compared with the HK2 group,the expression of p-AKT,FOXO3a,and p-FOXO3a elevated in the HK2+uric acid group;the expression of p-AKT further increased,while the expression of FOXO3a and p-FOXO3a decreased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,p-AKT expression decreased;FOXO3a and p-FOXO3a expression increased in the HK2+uric acid+siSLC2A12+MK-2206 group.(4)Compared with the HK2 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels increased in the HK2+uric acid group;interleukin-6,interleukin-1 β,and tumor necrosis factor α levels further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels diminished in the HK2+uric acid+siSLC2A12+MK-2206 group.(5)These findings indicate that SLC2A12 may protect against hyperuricemia-induced renal injury by counteracting uric acid-induced tubular fibrosis and inflammation through activation of the FOXO3a pathway.

Application of sacubitril/valsartan in patients with chronic kidney disease / 中华肾脏病杂志

As a new strategy for the application of sacubitril/valsartan (LCZ696) in patients with CKD, much evidence showed that it improved the prognosis of patients with CKD. This review summarizes the efficacy and safety of sacubitril/valsartan in physiology, pathology, pharmacology and clinical application by searching Wanfang, CNKI, PubMed and other databases for related articles on the application of sacubitril/valsartan in CKD patients. Although LBQ657, the active product of sacubitril, has a high drug accumulation in patients with moderate, severe renal injury, and ESRD, it is not cleared in hemodialysis, and has very little eliminated in peritoneal dialysis, which does not affect its safety. Compared with angiotensin converting enzyme inhibitor and angiotensin receptor blocker drugs, LCZ696 could increase the blood pressure control rate, improve cardiac function, slow down the decline of glomerular filtration rate, and significantly improve cardiovascular outcomes without more adverse events. Sacubitril/valsartan can be used in all levels of CKD patients complicated with hypertension and/or heart failure, with reliable safety and tolerance.

The role of DNA methylation detection in the early diagnosis and prognosis of lung cancer / 中华检验医学杂志

Lung cancer is the leading type of cancer death, and most patients with lung cancer are diagnosed at an advanced stage and have a very poor prognosis. Although low-dose computed tomography (LDCT) has entered the clinic as a screening tool for lung cancer, its false-positive rate is more than 90%. As one of the epigenetic modifications of research hotspots, DNA methylation plays a key role in a variety of diseases, including cancer.Hypermethylation of tumor suppressor genes and hypomethylation of proto-oncogenes are important events in tumorigenesis and development. Therefore, DNA methylation analysis can provide some useful information for the early screening, diagnosis, treatment and prognosis of lung cancer. Although invasive methods such as tissue biopsy remain the gold standard for tumor diagnosis and monitoring, they also have limitations such as inconvenience in sampling. In recent years, there has been a rapid development of liquid biopsy, which can detect primary or metastatic malignancies and reflect the heterogeneity of tumors. In addition, the blood sample can be collected in a minimally invasive or non-invasive format and is well tolerated in older and frail patients. This article explores some of the emerging technologies for DNA methylation analysis and provides an overview of the application of DNA methylation in the diagnosis and treatment of lung cancer.

Compareison of the efficacy of mPCNL and RIRS using 40-80 Hz holmium laser in the treatment of renal calculi / 现代泌尿外科杂志

【Objective】 To compare the clinical efficacy of high frequency holmium laser in the treatment of 2-3 cm renal calculi by minimally invasive percutaneous nephrolithotomy (mPCNL) and retrograde intrarenal surgery (RIRS). 【Methods】 The clinical data of 105 patients with a solitary 2-3 cm renal calculus treated during Oct. 2020 and Oct. 2022 were retrospectively analyzed. The patients were divided into two groups, including 52 cases in the RIRS group and 53 cases in the mPCNL group. The one-stage stone clearance rate, operation time, hemoglobin decline within 24 hours, inflammatory indicators within 24 hours after operation, postoperative complications, hospital stay and hospitalization costs were compared between the two groups. 【Results】 There were no significant differences in the preoperative general data, one-stage stone clearance rate, inflammatory indicators within 24 hours and incidence of postoperative complications between the two groups (P>0.05). The RIRS group had less decrease of hemoglobin than the mPCNL group [(6.35±2.00) g/L vs. (12.25±5.72) g/L, P=0.001], shorter hospital stay [(5.13±0.82) d vs. (7.92±1.59) d, P<0.001], lower hospitalization costs [(15 221.52±796.46) yuan vs. (19 514.51±909.98) yuan, P<0.001], but longer operation time [(58.17±7.67) min vs. (49.60±4.52) min, P<0.001]. 【Conclusion】 Both mPCNL and RIRS are safe and effective in the treatment of 2-3 cm renal calculi with 40-80 Hz holmium laser, and the one-stage stone clearance rate is similar. Although RIRS needed longer operation time than mPCNL, it has the advantages of less surgical trauma, faster postoperative recovery and shorter hospital stay, and is more prospective in the treatment of 2-3 cm renal calculi.
