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 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.

OBJECTIVETo evaluate the application of small intestine double stoma and succus entericus reinfusion in the patients with severe intra-abdominal infection.

METHODSTen patients with high intestinal perforation from February 2005 to November 2014 were enrolled in the study. All the cases received emergency operation. Small bowel with intestinal perforation was resected, and double stoma was applied in the proximal and distal small intestine. When abdominal infection under control, total enteral nutrition was successfully administered from nasogastric tube. The succus entericus from the proximal intestine was collected and transfused back to the distal intestine. Stool was collected and fecal nitrogen, fat and carbohydrate contents were determined. Related serum protein levels were measured.

RESULTSAs compared to pre-reinfusion, the absorption rate of carbohydrate [(90.9±7.8)% vs. (82.7±15.2)%], fat [(87.6±6.4)% vs. (59.1±10.8)%], and nitrogen [(82.4±9.8)% vs. (67.2±15.4)%] increased after succus entericus reinfusion (P<0.05). The serum protein levels increased significantly as well[fibronectin: (285.6±3.6) vs. (157.0±22.6) mg/L, P<0.01; transferrin: (4.86±0.21) vs. (3.60±0.25) g/L, P<0.05; pre-albumin: (291.3±112.5) vs. (199.1±53.3) mg/L, P<0.05].

CONCLUSIONSmall intestine double stoma and succus entericus reinfusion are effective in improving the absorption of carbohydrate, fat and nitrogen in the patients with severe intra-abdominal infection.
