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.

Objective:This study aimed to evaluate the immunoprotective effect of anti-rabies virus cocktail monoclonal antibody Zamerovimab/Mazorelvimab after rabies exposure.Methods:The dynamic data of rabies virus neutralizing antibody (RVNA) were analyzed in the Zamerovimab/Mazorelvimab Chinese phase Ⅲ study (clinical trial registration number: CTR20201819).Results:The full analysis set showed that RVNA geometric mean titers (GMT) on the 4 th, 8 th, 15 th, 43 rd, and 99 th day in the Zamerovimab/Mazorelvimab group were 4.413 IU/ml, 5.178 IU/ml, 17.062 IU/ml, 14.672 IU/ml, and 2.836 IU/ml, respectively, while those in the human rabies immunoglobulin (HRIG) group were 0.299 IU/ml, 0.451 IU/ml, 11.374 IU/ml, 18.063 IU/ml, and 6.769 IU/ml, respectively. The positive rates of RVNA on the 4 th, 8 th, 15 th, 43 rd, and 99 th day in the Zamerovimab/Mazorelvimab group were 99.9%, 99.6%, 100%, 100%, and 97.4%, respectively, while those in the HRIG group were 23.3%, 34.1%, 97.6%, 99.6%, and 98.4%, respectively. Conclusions:Compared with HRIG, Zamerovimab/Mazorelvimab cocktail monoclonal antibody reached the required protection level of RVNA very soon, thus effectively provided an immediate neutralizing effect of passive immunization therapies against rabies virus.

OBJECTIVETo investigate the feasibility and safety of 3D laparoscopic and thoracoscopic esophagectomy.

METHODSFrom October 2013 to March 2014, 154 patients with esophageal cancer of clinical stage T3N1M0 undergoing 3D or 2D minimally invasive esophagectomy in lateral prone position in our department were enrolled prospectively, and randomly divided into 3D group (78 cases) and 2D group (76 cases). The esophagus was dissociated by 3D or 2D laparoscope and thoracoscope to the entry of thorax. Stomach was dissociated by same telescopes and cut linearly. After tube stomach shaping was completed, esophagogastric anastomosis was performed in the left neck. The operative safety and short-term efficacy were compared between the two groups.

RESULTSThe entire procedure was technically successful in 154 patients. The average total operative time in 3D group was shorter than that in 2D group [(176.0±27.7) min vs. (203.0±31.5) min, P<0.05]. No significant differences were observed in blood loss [(124.0±35.8) ml vs. (127.0±25.7) ml], number of harvested lymph node (17.0±8.6 vs. 18.0±3.3), postoperative hospital stay [(11.8±9.3) d vs. (12.6±8.8) d] (all P>0.05), and morbidity of postoperative complication [12.8% (10/78) vs. 14.5% (11/76)]. The median follow-up time was 5.6 (3-8) months and 5.2 (5-7) months in 3D and 2D groups respectively, and no death or relapse cases were found during the follow-up.

CONCLUSION3D laparoscopic and thoracoscopic esophagectomy under lateral prone position is technically feasible and safe for esophageal carcinoma, as compared to 2D procedure.

OBJECTIVETo explore the effect of titanic elastic nailing (TEN) fixing for Pilon fractures complicated with fractures of fibula.

METHODSFrom March 2007 to March 2009, 20 patients with Pilon fractures complicated with fractures of fibula were surgically treated with TEN. There were 14 males and 7 females with an average age of 42.6 years ranging from 35 to 70 years. Among them, 12 cases were on the left, 8 cases were on the right.

RESULTSAll patients were followed-up for from 6 to 23 months (averaged 11.6 months). The symptoms of all patients had primarily relieved and the patients coulde ambulate at 2 to 3 months after treatment. According to Johner-Wruhs critera, the therapeutic results were excellent in 10 cases, good in 8 cases, fair in 2 cases. No case had skin infection and skin necrosis.

CONCLUSIONTreatment of Pilon fractures complicated with fractures of fibula with TEN has the advantages such as less invasion, high rate of bone union and less soft tissue complication, it is a safe and effective procedure.

OBJECTIVETo repair cartilage defects at non-weight-bearing area of the femoral condyle in rabbits with invitro amplified cartilage cell using calcium alginate column scaffold combined with calcium alginate gel injection, and to study repair effects of combination with different form of the same material.

METHODSTwenty-four New Zealand rabbits were divided into 4 groups randomly. The wounds of rabbits in the Group 1 were repaired with injection of calcium alginate gel; the wounds of rabbits in the Group 2 were repaired with in planting of calcium alginate column scaffold; the wounds of rabbits in the Group 3 were repaired with in planting of calcium alginate column supporter firstly, and then injection of calcium alginate gel at the surrounding; and Group 4 is control group, the rabbits in the group were repair and without any support. The repair effects were demonstrated with Xij, and the effects of all animals were studied with statistical analysis.

RESULTSThe Xij scores of each rabbits were calculated, and the scores in four groups were compared. The statistical results showed that combination therapy was better than other methods (F = 69.0, P < 0.05).

CONCLUSIONThe calcium alginate with column shape has better shaping effects and certain mechanical strength. The calcium alginate gel has better stick nature and can be used to integrate artifical material with normal structure. They can be used together, which meeting the desire of repair and integration in cartilaginous tissue engineering.
