Objective:To explore the effect of empagliflozin combined with levosimendan on plasma levels of type Ⅰcollagen(Collagen Ⅰ),connective tissue growth factor(CTGF),and α-smooth muscle actin(α-SMA)in patients with coronary heart disease(CHD)and heart failure(HF).Methods:This randomized controlled study enrolled 106 CHD+HF patients admitted to Linfen Central Hospital between June 2022 and June 2023.Patients were divid-ed into control group(n=53,treated with levosimendan)and combined treatment group(n=53,received addition-al empagliflozin).Both groups were treated for 12 weeks.The total effective rate,exercise endurance,cardiac function,levels of HF biomarkers,inflammatory factors,myocardial fibrosis indexes and incidence of adverse reac-tions were compared between two groups.Results:The total effective rate of combined treatment group was signif-icantly higher than that in the control group(94.34％vs.81.13％,P＜0.001).Compared with patients in the con-trol group,those in the combined treatment group had significant higher cardiac output(CO)[(4.62±0.89)L/min vs.(3.90±0.75)L/min],left ventricular ejection fraction(LVEF)[(55.42±6.09)％vs.(48.97±5.74)％]and 6-minute walking distance(6MWD)[(405.69±56.47)m vs.(295.65±41.32)m](P＜0.001 all),and signifi-cant lower levels of N-terminal pro B-type natriuretic peptide(NT-proBNP)[(192.06±29.02)pg/ml vs.(313.58±20.98)pg/ml],soluble suppression of tumorigenicity 2(sST2)[(53.33±5.79)μg/L vs.(60.04±6.88)μg/L],interleukin-1β(IL-1β)[(18.16±5.42)ng/L vs.(21.07±6.31)ng/L],high-sensitive C-reactive protein(hsCRP)[(1.69±0.41)mg/L vs.(1.98±0.56)mg/L],tumor necrosis factor α(TNF-α)[(0.87±0.26)ng/L vs.(1.19±0.32)ng/L],Collagen Ⅰ[(162.58±30.55)μg/L vs.(189.98±41.32)μg/L],CTGF[(114.26±14.89)μg/L vs.(125.87±19.47)μg/L]andα-SMA[(90.63±19.57)μg/L vs.(101.39±23.62)μg/L](P＜0.05 or＜0.01).There was no significant difference in the incidence of adverse reactions between two groups(15.09％vs.16.98％,P=0.791).Conclusion:Empagliflozin combined with levosimendan has a significant therapeutic effect in patients with coronary heart disease and heart failure,which calld significantly improve cardiac function,exercise endurance,reduce levels of heart failure biomarkers and inflammatory factors,and inhibit myo-cardial fibrosis.

Fracture healing is a complex process that necessitates the synergistic action of various cells and molecules. Macrophages play an indispensable and crucial regulatory role in the process of fracture repair, influencing stages such as inflammatory modulation, angiogenesis, and tissue remodeling. This article delves into the functional characteristics of macrophages and their roles at different stages of fracture healing. Additionally, it explores the impact of aging macrophages on the healing process. Furthermore, the potential of emerging therapies, such as hydrogel-based treatments and exosomes, in modulating macrophage responses is analyzed. This study provides a theoretical foundation for the development of innovative therapies aimed at enhancing the efficacy of fracture healing.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

This study was aimed at predicting the biological function of Streptococcus suis serotype 2(S.suis 2)tyrosine kinase Cps2C through bioinformatics and analyzing its effects on S.suis 2 pathogenicity.Online bioinformatics tools were used to analyze and predict the localization,conserved domains,transmembrane domains,protein similarity,and protein three-di-mensional structure of Cps2C.A BALB/c mouse infection model was used to compare and analyze clinical characteristics,mor-tality rates,and blood bacterial loads in mice infected with the wild-type strain 05ZYH33 and the cps2C gene knockout strainΔcps2C.Additionally,heart,brain,and joint tissue sections from infected mice were stained with hematoxylin and eosin(HE)for comparative pathological analysis.The Cps2C protein-coding gene is located upstream of the capsule biosynthesis locus cps,lacks transmembrane domains,is a homologous protein to Streptococcus pneumoniae tyrosine kinase CpsD with a 64％amino acid sequence similarity,and is potentially involved in bacterial capsule synthesis regulation.Cps2C deficiency significantly de-creased the pathogenicity of S.suis 2 in mice(P＜0.05).Compared with the wild-type strain,the Δcps2C strain showed a sig-nificantly lower blood bacterial load(P＜0.000 1).Heart,brain,and joint tissues of mice infected intraperitoneally with strains 05ZYH33 and Δcps2C remained structurally intact without e-dema,hemorrhage,or inflammatory cell infiltration;moreo-ver,characteristic lesion features of endocarditis,meningitis,or arthritis were absent.Streptococcus suis serotype 2 tyrosine kinase Cps2C may be an important regulatory factor in capsule biosynthesis,and its deficiency decreases bacterial blood survival capability and pathogenicity in mice.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.
