Objectives:This study aims to evaluate the relationship between the triglyceride-glucose body mass index(TyG-BMI),the right pericoronary fat attenuation index(RCA-FAI),and prognosis in patients with coronary artery disease(CAD).Methods:This study included 513 CAD patients who underwent coronary computed tomography angiography(CCTA)and coronary angiography between April 2018 and June 2023.Data collection and parameter calculations were performed for all research variables.The patients were stratified into three groups based on TyG-BMI tertiles:T1 group(TyG-BMI≤207.02,n=171),T2 group(207.02

Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

Disruption of normal secretion or mucociliary clearance can impair airway defense mechanisms and lung function, and increase the risk of infection. Airway clearance techniques are recommended as part of a comprehensive treatment plan for patients. Among these, vibratory expectoration is an important method of airway clearance, which loosens and liquefies mucus and metabolites on the surface of the respiratory tract through chest wall oscillation, promoting ciliary movement to facilitate sputum expulsion. However, commonly used handheld vibrating head devices and vest-type vibration expectorators have several limitations in clinical practice, such as inconvenience of operation, limited treatment time, poor adaptability, and difficulty in disinfection. To address these issues, the research team from the department of critical care medicine at Ruijin Hospital, Shanghai Jiao Tong University, has designed a novel belt-type vibration expectorator, which has been granted a national utility model patent (Patent No.: ZL 2023 2 1610983.1). The device is mainly composed of a chest strap assembly, a sputum clearance component, and a fixed shoulder strap component. Several pockets are placed on the outer surface of the chest strap, with corresponding inner-side openings that allow the percussion head of the percussive expectorator placed inside the pocket to make contact with the patient's chest wall. Each pocket has markings indicating the percussion position, enabling the placement of the percussive expectorator according to the location of infection, thereby achieving multi-point, precise percussive vibration expectoration in different body positions. On the inner side of the chest strap, there are diagrams illustrating postural drainage, providing guidance on the body positions patients should assume based on the location of infection. The hook-and-loop fasteners on both sides of the chest strap can be wrapped around and secured according to the patient's body shape, ensuring that the sputum clearance components adhere tightly to the chest wall, allowing the vibrations generated by percussion to be effectively transmitted to the patient's airways. Additionally, to prevent the chest strap from slipping due to changes in the patient's position, a Y-shaped fixing strap can be selectively attached to the chest strap for further stabilization. This innovation not only simplifies the operation process, improves convenience and flexibility of use, but also supports the principle of "disinfection after each use by one person," which helps to reduce the risk of nosocomial infections and improve the efficiency of patients' respiratory rehabilitation.

Objective This study aimed to investigate the relationship between malnutrition and coronary inflammation,and explore the interaction and mediating effects of coronary inflammation in the association between malnutrition and major adverse cardiovascular events(MACE).Methods A retrospective analysis was conducted on 428 patients diagnosed with coronary heart disease at the Central China Fuwai Hospital from May 2018 to July 2022.All patients underwent coronary angiography(CAG)and coronary computed tomography angiography(CCTA).The TCB index(triglycerides×total cholesterol×body weight)and the coronary fat attenuation index around the proximal right coronary artery(RCA-FAI)were used to assess patients' nutritional state and the degree of coronary inflammation,respectively.The study endpoint was MACE.We used linear regression models to analyze the correlation between TCBI and RCA-FAI,cox regression models to assess the correlation of TCBI and RCA-FAI with MACE,and mediation analysis to investigate whether RCA-FAI mediated the relationship between TCBI and MACE.Results A total of 428 patients were included in the study.There was a negative correlation between RCA-FAI and TCBI(r=-0.224,P<0.001).After adjusting for potential confounders,each standard deviation decrease in the TCBI index was associated with a 2.20 HU increase in RCA-FAI(95%CI:-3.40～-1.19,P<0.001).During a mean follow-up period of 2.15 years,51 MACE occurred.MACE risk in the low TCBI/high RCA-FAI group was 6.58 times higher than that in the high TCBI/low RCA-FAI group(adjusted HR=6.580,95%CI:2.237～19.360,P=0.001),and the interaction between TCBI and RCA-FAI was identified.Mediation analysis revealed that RCA-FAI mediated 37.5%of the associations between TCBI and MACE.Conclusions In patients with coronary artery disease,malnutrition is associated with increased coronary inflammation.There is a significant interaction between malnutrition and coronary inflammation in the risk of MACE,and coronary inflammation partially mediates the relationship between malnutrition and MACE.The combination of the TCBI index and RCA-FAI can help identify patients at high cardiovascular risk.Improving malnutrition and controlling coronary inflammation may provide addi-tional benefits for patients with coronary artery disease.

Kidney stones is the most common urinary system disease, among which calcium oxalate stones are the most common. The pharmacological treatment of calcium oxalate stones currently in use is associated with low compliance and a high incidence of adverse reactions. In recent years, plant extracts have demonstrated considerable potential in inhibiting renal calcium oxalate stones. This article introduces the role of plant extracts, including polysaccharides, polyphenols, alkaloids, flavonoids and organic acids, in the inhibition of calcium oxalate stones. It also provides a theoretical basis for the clinical prevention and treatment of calcium oxalate stones.
