Sepsis-acquired weakness (SAW) is a common complication in critically ill patients, yet significant gaps remain in both mechanistic understanding and therapeutic interventions for this condition. SAW not only prolongs the duration of mechanical ventilation and hospitalization but is also closely associated with increased mortality. Even if these SAW patients survive, they often experience long-term physical dysfunction after hospital discharge, leading to diminished quality of life. Emerging evidence suggests that sustained mitochondrial dysfunction may constitute a pivotal pathophysiological basis for the development and progression of SAW, primarily encompassing five key aspects: dysregulated mitochondrial quality control (MtQC), impaired oxidative phosphorylation (OXPHOS), exacerbated oxidative stress, disrupted Ca²⁺; homeostasis, and their mediation of diverse myofiber injuries. This article systematically elucidates the central role of mitochondrial dysfunction in the pathogenesis of SAW. Furthermore, we explore potential therapeutic strategies targeting mitochondrial function, including mitigating mitochondrial oxidative stress, optimizing nutritional support, and supplementing with muscle-derived mesenchymal stem cells. These insights provide a critical theoretical framework for understanding SAW mechanisms and developing clinical interventions, with particular emphasis on the translational value of mitochondrial-targeted therapies in improving outcomes for septic patients.

Objective:To investigate the effectiveness of the 5A (Ask, Assess, Advise, Assist, Arrange follow-up) management model based on personalized health education records in community patients with type 2 diabetes mellitus.Methods:A convenience sampling method was used to select patients with type 2 diabetes mellitus who were enrolled with family doctors in Yuxin Community, Haidian District, Beijing, from January 2022 to May 2023. Using a random number table method, the patients were divided into an observation group ( n=68) and a control group ( n=68). The control group received routine community management, while the observation group received management based on the 5A model and personalized health education records. Differences in metabolic indicators, including glycated hemoglobin (HbA1c), fasting blood glucose, 2-hour postprandial blood glucose, body mass index (BMI), and waist circumference, as well as self-management behaviors were compared between the two groups at 3, 6, and 12 months of intervention. Results:During the entire intervention period, four cases were lost in the observation group and eight cases were lost in the control group. Finally, data from 124 patients were included in the analysis, including 64 cases in the observation group and 60 cases in the control group. Repeated measures analysis of variance showed interaction effects between time points and groups for HbA1c, BMI, waist circumference, and self-management behavior scores among patients with diabetes, with statistically significant differences ( P<0.05) . Conclusions:The 5A management model based on personalized health education records has a positive impact on improving metabolic indicators and self-management behaviors in community patients with type 2 diabetes mellitus.

The present study aims to explore the genetic diversity of germplasm resources of Chrysanthemum×morifolium (hereinafter, C.×morifolium) at the molecular level and to establish a fingerprint database of C.×morifolium varieties. We employed 12 pairs of primers with high levels of polymorphism, clear bands, and high degrees of reproducibility to analyze the SSR molecular markers and genetic diversity of 91 C.×morifolium materials and 14 chrysanthemum- related materials. With regard to constructing the fingerprints of the tested materials, we chose 9 pairs of core primers. The findings revealed that 12 primer pairs detected 104 alleles in 105 samples, ranging from 2 to 26. The average number of observed alleles (N_a) per site was 9.25. The average number of effective alleles (N_e) per site was 2.745 6, with its range being 1.276 0 to 4.742 5. Shannon genetic diversity index (I) values ranged between 0.513 3 and 2.239 9 (M=1.209 0). Nei's gene diversity index (H) ranged between 0.216 3 and 0.789 1 (M=0.578 0). The observed heterozygosity (H_o) ranged between 0.223 3 and 0.895 2 (M=0.557 5). The expected heterozygosity (H_e) ranged between 0.217 4 and 0.793 3 (M=0.580 8). The polymorphism information content (PIC) ranged between 0.211 5 and 0.774 0 (M=0.532 9). The genetic similarity (GS) ranged between 0.228 5 and 1.000 0 (M=0.608 3). Cluster analysis revealed that when the genetic distance (GD) equals to 0.30, the tested materials can be classified into 2 groups. When the GD equals to 0.27, the first group can be divided into 6 subgroups; accordingly, 105 tested materials can be divided into 7 subgroups. The cophenetic correlation test was carried out based on the cluster analysis, and the corresponding results showed that the cluster map correlated with the genetic similarity coefficient (r=0.952 73). According to the results of Structure population analysis, we obtained the optimal population number, with the true number of populations (K) being 3 and the population being divided concerning Q≥0.5. Three subgroups, i.e., Q1, Q2 and Q3, included 34, 33 and 28 germplasms, respectively, and the remaining 10 germplasms were identified as the mixed population. During the experiment, 9 pairs of core primers were screened among the total of 12 for a complete differentiation regarding 105 tested materials, and the fingerprints of 91 C.×morifolium materials and 14 chrysanthemum-related materials were further constructed. Overall, there were significant genetic differences and rich genetic diversity among C.×morifolium materials, which would shed light on the garden application and variety selection fields of C.×morifolium. The fingerprint database of 105 C.×morifolium varieties and chrysanthemum-related species may provide technical support for future research regarding the identification and screening system of C.×morifolium varieties.

Objective:To explore the factors associated with severe bleeding after percutaneous nephrolithotomy (PCNL) in male patients and evaluate the efficacy of interventional embolization.Methods:A retrospective case series study was conducted at Nankai Hospital of Tianjin, China, from January 2018 to October 2021. The clinical data of 230 male patients with upper urinary tract stones were analyzed. The observation indicators included age, hypertension, diabetes, renal function abnormalities, history of preoperative anticoagulant use, stone size, stone type, number of puncture channels, operation time and degree of hydronephrosis. To describe the clinical characteristics of bleeding after percutaneous nephrolithotomy in men, and analyze the factors associated with severe bleeding after PCNL. Single factor analysis was performed using the Chi-square ( χ2) test, and multivariate analysis was performed using logistic regression analysis. Results:Univariate analysis showed that diabetes mellitus ( χ2=4.90, P=0.027), abnormal renal function ( χ2=18.32, P<0.001), history of preoperative oral anticoagulants ( χ2=5.10, P=0.024), abnormal bleeding and coagulation function ( χ2=8.22, P=0.004) and the number of puncture channels ( χ2=22.08, P<0.001) were the related factors affecting bleeding after PCNL. Multivariate logistic regression analysis showed that diabetes mellitus ( P=0.032), abnormal renal function ( P<0.001), and the number of puncture channels ( P<0.001) were the independent risk factors of bleeding after PCNL. Of the 28 patients with bleeding after PCNL, 25 were treated with interventional embolization, with a technical success rate of 100.0% and a clinical success rate of 89.3%. Conclusions:For patients with renal calculi and comorbid diabetes, renal function abnormalities, and multiple punctures, relevant preventive measures should be actively administered before PCNL to reduce the risk of postoperative bleeding. For patients with severe bleeding of the kidney after PCNL, TAE is a safe and effective minimally invasive treatment method.

There are a large number of atypical symptoms and undifferentiated diseases in general practice, in which sociological factors are deeply involved.
