The surgical treatment of thoraco-abdominal aortic aneurysm (TAAA) requires a unique multidisciplinary approach. A thorough preoperative examination and evaluation are essential to determine the optimal timing for surgery and to optimize organ function as needed. During the perioperative period, excellent surgical skills and an appropriate strategy for extracorporeal circulation will be employed based on the extent of the aneurysm. Additionally, necessary measures will be taken to monitor and protect the functions of vital organs. Close monitoring and management in the postoperative stage, along with early detection of complications and effective treatment, are crucial for improving the prognosis of TAAA surgery. This article reviews the current research progress in the perioperative management of TAAA surgery.

Background With economic development and globalization, shift work has become prevalent across industries. Its relationship with type 2 diabetes mellitus (T2DM) attracts increasing attention. Objective To thoroughly explore the relationship between shift work and T2DM, and analyze the impacts of specific shift patterns on T2DM, so as to provide a basis for formulating reasonable shift schedules. Methods We conducted a 1:2 matched case-control study among adults (20-60 years) who ordered occupational health examinations at the Wuxi No.8 People's Hospital from November to December 2023. The case group comprised 200 T2DM patients, while the controls were 400 age-stratified matched non-diabetic individuals. General demographic characteristics, behavioral habits, medical history, and shift work exposure data (including shift patterns, frequency, and length of service) 5 years prior to diagnosis were collected through standardized questionnaires. Logistic regression adjusted for selected confounders was employed to evaluate the association between shift work and T2DM. Results The logistic regression analysis demonstrated that shift work was associated with an increased risk of T2DM. After adjusting for confounding factors, shift workers had a 3.55 times higher risk of being diagnosed T2DM compared to non-shift workers (OR=3.55, 95%CI: 1.026, 12.263). The risk varied across different shift patterns, and the three-shift two-rotation system showed the highest risk (OR=4.17, 95%CI: 1.921, 9.035), followed by the two-shift system (OR=2.94, 95%CI: 2.016, 4.281) and four-shift three-rotation system (OR=2.66, 95%CI: 1.611, 6.093). Workers with more than 3 monthly shift days had a 2.74-fold increased risk (95%CI: 1.658, 4.512) compared to non-shift workers. Additionally, working more than 8 h daily (OR=1.74, 95%CI: 1.185, 2.562) and having more than 20 years of service (OR=2.51, 95%CI: 1.581, 3.976) were both significantly associated with a higher T2DM risk. The trend tests revealed that each incremental increase in monthly shift days and length of service elevated T2DM risk by 2.61 times (95%CI: 1.813, 3.765) and 1.49 times (95%CI: 1.147, 1.931), respectively (P<0.05). Conclusion Shift work is an independent risk factor for T2DM, with three-shift two-rotation system posing the highest risk. Shift frequency, daily working hours, and length of service are all significant factors affecting the risk of T2DM. These findings support industry-specific shift policy reform and targeted glucose monitoring and health interventions are recommended for workers engaged in high-risk shift patterns (e.g., three-shift two-rotation system, frequent shifts) and those with prolonged shift work history (>20 years).

BACKGROUND:Although traditional screw fixation has been successful in treating ankle fractures,rigid fixation solutions tend to restrict ankle movement and delay fracture healing,whereas elastic fixation is more compatible with human mechanics and has unique advantages in patients with ankle fractures. OBJECTIVE:To compare the clinical effectiveness of elastic fixation and absolute fixation in repairing ankle fractures in the elderly with lower tibiofibular instability. METHODS:The clinical data of 108 elderly ankle fractures with lower tibiofibular instability in Hengshui People's Hospital from August 2019 to August 2021 were retrospectively collected.They were divided into screw group and elastic fixation group(n=54 per group)according to the surgical protocol,and traditional screw internal fixation and elastic internal fixation were performed respectively.The perioperative indicators,surgical results,economic benefits,and American orthopedic foot and ankle society scores were collected and compared between the two groups.Serum tumor necrosis factor-α,interleukin-8 levels,ankle cavity width,depth,and lower tibiofibular space were compared before and after surgery. RESULTS AND CONCLUSION:(1)The full weight-bearing time was shorter in the elastic fixation group than that in the screw group;the operating angle was greater in the elastic fixation group than that in the screw group,and the complication rate was lower in the elastic fixation group than that in the screw group(P<0.05).(2)Serum tumor necrosis factor-α and interleukin-8 levels in the elastic fixation group were lower than those in the screw group 3 days after surgery(P<0.05).(3)American orthopedic foot and ankle society scores in the two groups were higher than those before surgery at 6 and 12 months after surgery,and the depth and width of the inferior tibiofibular space and ankle cavity were lower than those before surgery(P<0.05);but no significant difference was detected between the two groups(P>0.05).(4)There was no significant difference in the excellent and good rate between the two groups at 12 months after surgery(P>0.05).(5)There was no significant difference in the comparison of direct non-medical costs,direct medical costs,and total costs between the two groups(P>0.05).(6)It is indicated that elastic fixation for the repair of ankle fractures with lower tibiofibular instability in the elderly can obtain effective outcomes,which can shorten the time of complete weight-bearing,diminish complications,and alleviate inflammatory stress.

BACKGROUND:The displacement change parameters of the bone structure of the first metatarsal bone at the two-dimensional level of hallux valgus deformity are of great significance for clinical diagnosis and treatment,while the quantitative analysis of the three-dimensional deformity index may have some influences on the postoperative efficacy. OBJECTIVE:To explore the quantitative change of the three-dimensional deformity index of the first metatarsal bone after routine osteotomy and orthosis for hallux valgus deformity and to provide reference for clinical work. METHODS:100 patients with hallux valgus deformity(foot)in Hengshui People's Hospital from October 2020 to April 2023 were selected and all of them underwent conventional osteotomy and orthosis.Foot function was assessed by the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale 6 months after surgery.Anterolateral X-rays of the foot in weight-bearing position and CT images in simulated weight-bearing position were taken before surgery and 6 months after surgery.The three-dimensional deformity indexes of the first metatarsal bone before and after surgery were quantitatively analyzed in patients with different ages,genders and therapeutic effects,including first-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle.The value of the difference of three-dimensional deformity indexes of the first metatarsal bone before and after operation in evaluating the curative effect was analyzed. RESULTS AND CONCLUSION:(1)Six months after operation,the American Orthopedic Foot and Ankle Society score was 75-98(88.25±4.14)points,among which 56 cases were excellent,28 cases were good,14 cases were average,and 2 cases were poor.The excellent and good rate was 84%(84/100).(2)Compared with the preoperative results,first-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle were significantly improved in patients of different ages and genders 6 months after surgery(P<0.05).First-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle were all lower in patients with good curative effect 6 months after surgery than those with poor curative effect,and the difference before and after surgery was greater than those with poor curative effect(P<0.05).(3)The area under the curve of the difference evaluation of the first metatarsal three-dimensional deformity index before and after surgery was above 0.7,and the area under the curve of the combined evaluation of all indexes was the largest(0.902),which was significantly greater than the first metatarsal rotation α angle and distal metatarsal articular angle(P<0.05).(4)The quantitative analysis of the three-dimensional deformity index of the first metatarsal in patients with hallux valgus deformity is related to the postoperative effect,which has important guiding significance for improving the accuracy and comprehensiveness of preoperative evaluation and improving the treatment plan.

Objective:Berberine hydrochloride(BBR)is commonly used for the treatment of ulcerative colitis(UC),but its molecular mechanism,especially the mechanism of rescue of inflammatory-induced pyroptosis,needs to be further analyzed.Meth-ods:SD male rats were randomly divided into four groups:control group(Ctrl),DSS model group,BBR treatment group(DSS+BBR)and BBR+NLRP3 agonist group(DSS+BBR+BMS-986299).The UC rat model was established by the dextran sulfate sodium method(DSS).At the same time,BBR was intragastrically administered to BBR treatment group and BBR+NLRP3 agonist group twice per-day for 7 consecutive days.BMS-986299 was intraperitoneally injected to BBR+NLRP3 group twice a day.During the experiment,the body weights were weighed,the general condition was observed,and the disease activity index(DAI)was evaluated every day.After the experiment,the gross morphology and length of colon were observed and evaluated.HE staining was used to observe the pathologi-cal changes of colon tissue and evaluate the tissue injury index(TDI).ELISA was employed for detecting the contents of TNF-α and IL-1β in colon tissue,and Western blot was employed for detecting NLRP3,ASC,GSDMD-N,Cleaved-caspase 1 and IL-1β expres-sions.Results:BBR could effectively improve the UC-induced weight loss,colon tissue integrity and cell pyroptosis,reduce the expression levels of inflammatory factors such as TNF-ɑ and IL-1β,the proportion of pyroptosis,and the levels of proteins NLRP3,IL-1β,GSDMD-N,and Cleaved-caspase 1 which play crucial roles in pyroptosis pathway.The therapeutic effect and the regulated pro-tein expression through BBR were reversed by NLRP3 activation.Conclusion:BBR exerts a therapeutic effect by reducing the proteins levels of mature NLRP3,IL-1β,GSDMD-N,Cleaved-caspase 1,which are responsible for pyroptosis pathway.This result provides a molecular basis for BBR in treatment of UC.

Objective:To investigate the changing trends in cardiac function following xenogeneic heterotopic heart transplantation of multi-gene edited pig hearts and assess the impact of recipient immune responses on donor heart, laying experimental groundwork for the clinical application of gene editing technology.Methods:On December 16, 2023, xenogeneic heterotopic heart transplantation was performed between pigs and rhesus monkeys. Functional status of the graft under post-transplantation load conditions and recipient immune indicators were observed.Results:The recipient monkeys survived for 40 days with satisfactory functionality of both donor and recipient hearts, and no hyperacute or acute immune rejection reactions were observed.Conclusion:Multi-gene editing technology provides potential for xenotransplantation, yet further exploration is needed for its clinical application.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a salvage therapy for patients suffering cardiac arrest refractory to conventional resuscitation, and provides circulatory support in patients who fail to achieve a sustained return of spontaneous circulation. ECPR serves as a bridge therapy that maintains organ perfusion whilst the underlying etiology of the cardiac arrest is determined and treated. Increasing recognition of the survival benefit associated with ECPR has led to increased use of ECPR during the past decade. Commonly used indications for ECPR are: age<70 years, initial rhythm of ventricular fibrillation or ventricular tachycardia, witnessed arrest, bystander cardiopulmonary resuscitation within 5 min, failure to achieve sustained return of spontaneous circulation within 15 min of beginning cardiopulmonary resuscitation. This review provides an overview of ECPR utilization, recent outcomes, risk factors, and complications of ECPR. Identifying ECPR indications, rapid deployment of extracorporeal life support equipment, and high-quality ECPR management strategies are of paramount importance to improve survival.

Objective To observe neuropsychological development status in children after surgical treatment of congenital heart diseases(CHDs)and analyze the risk factors. Methods 89 children who received outpatient review in Fuwai Hospital from September 2015 to March 2016 after surgical treatment of CHDs were recruited in this study and 90 normal children were recruited as the control group. The children with CHDs were divided into simple CHDs group(RACHS- 1 score≤2)and com-plex CHDs group(RACHS- 1 score≥3)according to RACHS- 1 classification. Neuropsychological development status was meas-ured according to pediatric-psychological mental test scale developed by Capital institute of pediatrics,Beijing and statistical a-nalysis was compared. Results The measurements of neuropsychological development showed the normal children behaved better than the children with CHDs(P < 0. 05). The simple CHDs group achieved better distribution of development quotient than complex CHDs group(P = 0. 032)and there was no difference between the normal control group and simple CHDs group (P = 0. 420). Multivariate regression analysis indicated that younger age at cardiac surgery,lower preoperative blood urea ni-trogen(BUN),higher preoperative creatinine(Cr)and prolonged duration of cardiopulmonary bypass(CPB)accounted for low-er scores in the test scale(P < 0. 05). Conclusion Distinct neuropsychological difficulties could be present especially in chil-dren with complex CHDs. Younger age at cardiac surgery,preoperative BUN,Cr and CPB duration were perioperative factors that were associated with long-time neuropsychological development.

Objective To evaluate the long?term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)for gastric variceal bleeding. Methods A retrospective analysis was performed on the data of 65 cirrhotic patients with type 1 isolated gastric variceal bleeding in the First Affiliated Hospital of Anhui Medical University from January 2014 to January 2016.Patients were divided into two groups,TIPS treatment group(n=28),and gastric variceal obturation(GVO)treatment group(n=37). The long?term follow?up results of the two groups were compared. Results Operations of the two groups were succeed. Postoperative complications in the TIPS group and GVO group were 7.14%(2/28)and 13.51%(5/37), respectively, (P=0.801).Nine cases(32.14%)had mild hepatic encephalopathy in the TIPS group,and no occurred in the GVO group. During the 20.18 ± 6.90 months of follow?up in the TIPS treatment group, 2(7.14%) patients died, and the cumulative rebleeding?free rate at 6, 12 and 18 months was 88.4%, 83.7% and 76.1%,respectively.During the 16.14±6.03 months of follow?up in the GVO treatment group,5(13.51%) patients died, and the cumulative rebleeding?free rate at 6, 12 and 18 months was 86.5%, 70.2% and 60.9%,respectively. The survival rate between the two groups had no significant difference(P=0.690). There was a statistically significant difference in the cumulative non?bleeding rate in 18 months of follow up(log?rank test,χ2=6.304,P=0.012). Conclusion TIPS is superior to GVO for controlling gastric variceal bleeding in the long run,but clinicians should be vigilant to the occurrence of hepatic encephalopathy after operation.

Objective To evaluate the value of a new platelet function test PFA P2Y (PFA-200) in monitoring clopidogrel treatment for cardiovascular disease in elderly patients. Methods Fifty-six elderly patients receiving clopidogrel therapy in the Department of Cardiology of General Hospital of PLA from March to August in 2016 and 85 healthy volunteers were recruited for analysis. All the subjects underwent PFA P2Y, LTA (light transmittance aggregometry) and TEG (Thromboelastograph) tests, and Spearman correlation coefficients were used to test the associations between test results. The agreement among the 3 platelet function test methods was assessed using Cohen's kappa coefficient. Results Correlation coefficient (r) was-0.701 (P<0.001) between PFA P2Y and LTA, and 0.475 (P<0.001) between PFA P2Y and TEG. The agreement was 75%between PFA P2Y and LTA and 67.9%between PFA P2Y and TEG. Theκvalue was 0.434 (P=0.001) between PFA P2Y and LTA and 0.242 (P=0.046) between PFA P2Y and TEG. With ADP-induced maximum platelet aggregation rate of LTA>50%as the laboratory clopidogrel resistance, the cut-off value of PFA P2Y was 119 s (AUC=0.733) with a sensitivity of 75.6% and a specificity of 73.3%. Conclusion PFA P2Y has a moderate correlation and agreement with LTA, but has a poor correlation and agreement with TEG. PFA P2Y can be useful for assessing the effects of clopidogrel therapy and the association of the cut-off value (119 s) with the long-term clinical ischemic events needs be confirmed in further study.
