Objective To compare the differences in clinical characteristics between persistent atrial fibrillation(PsAF)combined with heart failure with preserved ejection fraction(HFpEF)and heart failure with reduced ejection fraction(HFrEF),and to clarify the influencing factors and predictive efficacy of PsAF combined with heart failure(HF).Methods A total of 117 inpatients with PsAF admitted to Laiyang Hospital of Traditional Chinese Medicine from February 2023 to February 2025 were selected and divided into PsAF+HFpEF group(n=42),PsAF+HFrEF group(n=34),and PsAF group(n=41)according to the type of HF.The baseline data,serum uric acid(UA)levels and echocardiographic parameters[left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),left atrium diameter(LAD),right ventricular diameter(RVD),left ventricular end diastolic volume(LVEDV),left ventricular end systolic volume(LVESV),stroke volume(SV)and pulmonary artery systolic pressure(PASP)]of three groups of patients were compared.Multivariate Logistic regression analysis was used to identify the independent influencing factors of PsAF combined with HF,and the receiver operating characteristic(ROC)curve was drawn to evaluate the predictive efficacy.Results The proportions of New York Heart Association(NYHA)cardiac function grade Ⅲ-Ⅳ and hyperuricemia,and heart rate,N-terminal pro-brain natriuretic peptide(NT-proBNP),UA in patients of PsAF+HFpEF group and PsAF+HFrEF group were significantly higher than those in PsAF group(P＜0.05).The serum creatinine level of patients in PsAF+HFrEF group was significantly higher than that in PsAF+HFpEF group and PsAF group(P＜0.05).The levels of LVESD,LVEDD,LAD,RVD,PASP,LVEDV and LVESV in PsAF+HFrEF group were significantly higher than those in PsAF group(P＜0.05).The LVESD,LVEDD,LAD,LVEDV and LVESV of patients in PsAF+HFpEF group were significantly lower than those in PsAF+HFrEF group(P＜0.05),LAD and PASP were significantly higher than those in PsAF group(P＜0.05).There was a statistically significant difference in LVEF among three groups of patients(P＜0.05),in sequence:PsAF group＞PsAF+HFpEF group＞PsAF+HFrEF group.Multivariate Logistic regression analysis showed that NT-proBNP,UA,and NYHA cardiac function grade Ⅲ-Ⅳ were all independent risk factors for PsAF complicated with HF,and LVEF was an independent protective factor(P＜0.05).The area under the curve for combined prediction of PsAF combined with HF by NT-proBNP+UA+LVEF was 0.967.Conclusion NT-proBNP,UA and LVEF are all independent predictors of PsAF complicated with HF.The combination of three has highly efficient predictive value and provides an efficient tool for clinical risk stratification.

OBJECTIVE To assess the current status of hospital-acquired infections and their economic burden in or-thopedic patients based on diagnosis-related groups(DRG).METHOD Based on the National Health Insurance dis-ease diagnosis-related groups,32 413 orthopedic patients from a tertiary care hospital in Beijing in 2021 were grouped,hospital-acquired infections were retrospectively analyzed,and the direct and indirect economic burdens of different DRG groups were assess using indictors such as hospitalization time and cost,bed turnover loss,and labor time loss.RESULTS A total of 32 413 patients were included,the incidence of hospital-acquired infection was 0.47％(153/32 413),the site of infection was predominantly the surgical site(57.99％),and hospital-acquired infections in the hematologic system had a greater impact on cost-consumption indices and time-consumption indi-ces.The infection cases were concentrated in 19.58％of the DRGs groups.The IF23 group(lower limb bone sur-gery with complications and comorbidities)had the highest direct economic burden(24 010 yuan/case)due to hos-pital-acquired infections,and the increase in the cost of consumables and medication was the main factor causing the direct economic burden.At both the hospital level and family-society level,the top three DRG groups in terms of indirect economic burden due to hospital-acquired infections were IB15,IB13 and IF23.CONCLUSION Hospital-acquired infections in orthopedic patients have a tendency to be concentrated,quantitatively assessment of their e-conomic burden based on DRGs not only illustrates the importance of hospital-acquired infection prevention and control,but also accurately identifies the disease groups that require focused management,providing an evidence-based basis for precise prevention and control of hospital-acquired infections.

Objective To investigate the effect of Yantiao Fang on apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury caused by sepsis by regulating the Rho/ROCK signaling pathway.Methods Seventy BALB/c mice were randomly divided into normal,sham,and model groups.Except for normal and sham groups,mice were subjected to cecal ligation and perforation to establish a mouse model of acute gastrointestinal injury caused by sepsis.The mouse models were randomly divided into model,Low,Medium,and High dose of Yantiao Fang,and ROCK inhibitor groups.Histopathological changes of the ileum were observed by HE staining.Serum levels of IL-1β,IL-6,TNF-α,and IL-10 were measured by ELISA.PCNA and Ki-67 expression was detected by immunohistochemistry.Cleaved caspase3 and Bax expression was detected by Western blot.ROCK and MLC mRNA expression in the ileum was measured by RT-qPCR.Results Compared with normal and sham groups,Chiu's pathological score,proinflammatory factor(IL-1β,IL-6,and TNF-α)levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were increased in the model group(P＜0.05).Moreover,anti-inflammatory mediator IL-10 and expression of PCNA and Ki-67 in the ileum were decreased in the model group(P＜0.05).Compared with the model group,histopathological changes of the ileum in all Yantiao Fang groups were improved by various degrees with the increase in dose.Chiu's pathological score,IL-1β,IL-6,and TNF-α serum levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were decreased in Yantian Fang groups(P＜0.05).The IL-10 level and expression of PCNA and Ki-67 in the ileum were increased in Yantian Fang groups(P＜0.05).Conclusions Yantiao Fang may inhibit apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury due to sepsis by regulating the Rho/ROCK signaling pathway,thereby alleviating intestinal tissue inflammation and ultimately preventing intestinal mucosal tissue injury.

ObjectiveTo validate the alleviating effect of Gegen Qinliantang （GGQLT） on insulin resistance in db/db diabetic mice by regulating the silent information regulator 1 （SIRT1）/forkhead transcription factor O1 （FoxO1） autophagy pathway. MethodSeventy-five SPF-grade spontaneous type 2 diabetic db/db mice and 15 control db/m mice were selected and maintained on regular feed for one week before measuring blood glucose. They were randomly divided into six groups， with 15 mice in each group. The groups included a normal group （physiological saline， 0.2 g·kg^-1）， a metformin group （0.2 g·kg^-1）， high-， medium-， and low-dose GGQLT groups （31.9， 19.1， 6.9 g·kg^-1）， and a model group （physiological saline， 0.2 g·kg^-1）. They were orally treated with corresponding drugs for eight weeks， once daily. Fasting blood glucose （FBG） was measured using a Roche glucometer. Serum levels of high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， triglyceride （TG）， and total cholesterol （TC） were measured using an automated biochemical analyzer. Fasting serum insulin （INS） levels were determined using enzyme-linked immunosorbent assay （ELISA）， and the homeostasis model assessment of insulin resistance （HOMA-IR） was calculated. Western blot was used to detect the expression of Beclin-1， microtubule-associated protein 1 light chain 3 （LC3）， and SIRT1/FoxO1 autophagy pathway-related proteins in liver tissues. Immunohistochemistry was performed to assess the expression of SIRT1， FoxO1， Beclin-1， and LC3B proteins in liver tissues. Transmission electron microscopy was used to observe the formation of autophagosomes in the liver. ResultCompared with the normal group， the model group showed significant increases in FBG， FINS， HOMA-IR， TC， TG， LDL-C， and HDL-C levels （P<0.01）， and significant increases in the expression of SIRT1， Beclin-1， LC3， and FoxO1 proteins in liver tissues （P<0.01）. Transmission electron microscopy revealed the highest number of autophagosomes in the model group. Compared with the model group， the metformin group and the low-， medium-， and high-dose GGQLT groups showed significant decreases in serum FBG， FINS， HOMA-IR， TC， TG， LDL-C， and HDL-C levels （P<0.05， P<0.01）， significant decreases in the expression of SIRT1， Beclin-1， LC3 （P<0.05， P<0.01）， and up-regulated FoxO1 protein （P<0.01）. Transmission electron microscopy showed a reduction in the degree of autophagy in the treatment groups. Compared with the metformin group， the medium- and high-dose GGQLT groups showed significant decreases in FBG， FINS， and TG levels （P<0.01）， significant decreases in the expression of SIRT1， Beclin-1， and LC3 in liver tissues （P<0.05， P<0.01）， and reduced FoxO1 protein （P<0.01）. The high-dose GGQLT group showed reduced HOMA-IR， TC， LDL-C， and HDL-C levels （P<0.05， P<0.01）. Transmission electron microscopy revealed a significant reduction in autophagosomes in the medium- and high-dose GGQLT groups. ConclusionGGQLT can significantly improve glucose and lipid metabolism disorders， alleviate insulin resistance in db/db mice， and prevent and treat type 2 diabetes by activating the SIRT1/FoxO1 autophagy pathway.

Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.
