Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Sepsis is a critical illness with high morbidity and mortality. Anaerobic glycolysis plays an important role in the pathogenesis of sepsis. Pyruvate dehydrogenase complex (PDHC) serves as a key regulator during sepsis. With PDHC dephosphorylation and deacetylation, PDHC activity is upregulated, allowing pyruvate translocate to mitochondria in aerobic condition, preceding the production of acetyl-CoA to accelerate aerobic oxidation. Activation of PDHC improves the prognosis of sepsis through regulating the balance of lactate, release of inflammatory factors and energy metabolism. A variety of remedies can improve the prognosis of patients with sepsis by up-regulating the activity of PDHC, including dichloroacetate (DCA), vitamin B1, milrinone, tumor necrosis factor binding protein, and ciprofloxacin.This article reviews the role and the regulatory mechanism of PDHC and signal pathway in the sepsis metabolism, in order to innovate treatment for sepsis and multiple organ dysfunction.

Objective: To investigate the value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis (UVCP). Methods: From May 2015 to April 2018, 51 patients with UVCP and 59 healthy controls in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, were involved in this research retrospectively. The UVCP patients were diagnosed with stroboscopic laryngoscopy. The minimum glottal area (MGA) was calculated by KIPS software when the people were pronouncing/i:/. The fundamental frequency (F0), Jitter, Shimmer and NHR were detected by CSL4500 multiple acoustic voice analyzer. Results: MGA of UVCP patients was much higher than that of healthy control (male: 433.68±64.52 vs. 294.41±51.82, t=9.23, P=0.000; female: 498.80±73.42 vs. 302.03±76.54, t=13.21, P=0.000), which meaned vocal cord insufficiency.After voice therapy, MGA reduced significantly (male: 288.48±55.09, female: 258.22±57.17, t=24.41 and 31.22, P=0.000 vs. pre-therapy). MGA of untreated patients decreased in varying degrees. Compared with the voice therapy group, the MGA decreased in a significantly lower extent (24.25±22.91 vs. 188.31±54.37, t=8.97, P=0.000). The F0, Jitter, Shimmer and NHR raised significantly in UVCP patients group (P=0.000 vs. healthy control group), and they were reduced by voice therapy (all P<0.05). Each of the four acoustic parameters was relative with MGA, r=0.551, 0.867, 0.853 and 0.875 in turn, P=0.001, 0.000, 0.000, and 0.000. Conclusion MGA and acoustic parameters can reflect the acoustic features of UVCP patients, which are useful tools in the UVCP assessment and voice therapy.

This paper aims to explore the feasibility of building a finite element model of left atrial diverticulum (LAD) using reverse engineering software based on computed tomography (CT) images. The study was based on a three-dimensional cardiac CT images of a atrial fibrillation patient with LAD. The left atrium and LAD anatomical features were accurately reproduced by using Geomagic Studio 12 and Mimics 15 reverse engineering software. In addition, one left atrial model with LAD and one without LAD were created with ANSYS finite element analysis software, and the validity of the two models were verified. The results show that it is feasible to establish the LAD finite element model based on cardiac three-dimensional CT images using reverse engineering software. The results of this paper will lay a theoretical foundation for further hemodynamic analysis of LAD.

Objective This study reviews the 198 consecutive mitral valve operations for elderly patients(＞ 65 y) with ischemic mitral insufficiency performed at Anzhen Hospital between January 2000 and june 2016.The results for mitral valve reconstruction are compared with those for biological mitral valve replacement.Methods From January 2000 to June 2016,198 elderly patients with ischemic mitral insufficiency underwent mitral valve reconstruction (n =150) or biological mitral valve replacement(n =48).All of them coronary artery bypass gafting was performed at the same time.Preoperative clinical characteristics,procedural characteristics,major and minor complications after surgery,preoperative and postoperative left ventricular ejection fraction (LVEF) by echocardiography,and outcome (survivor or death,mitral regurgitation,NYHA degree) were assessed.Results There was no significant difference between the two groups in the rate of mortality during hospitalization and early postoperative cardiac function.The proportion of severe MR in 1,3,and 5 years after MVP were 5.1％ 、6.3％、7.7％ respectively.There was no MVR due to the recurrent moderate-to-severe reflux.There were 2 SBE but no reflux appeared after MVR.There was no significant difference in cardiac function and mortality between the two groups within 5 years.Conclusion There is no significant difference between CABG + MVP and CABG + MVR(BV) in cardiac function and mortality in the treatment of elderly patients with IMR.,There was a possibility of MR recurrence after CABG + MVP.There was no MR after CABG + MVR(BV),but the risk of SBE is higher than MVP.We can select operation mode personalized according to the type of mitral valve disease and cardiac function.

OBJECTIVE To investigate the effect of obstructive sleep apnea hypopnea syndrome(OSAHS) on the quality of voice. METHODS Electroglottography (EGG) method was used for detecting the vocal cords vibration, waveforms of electroglottography and voice parameters such as Jitter, Shimmer, normalized noise energy (NNE), contact quotient(CQ), contact index (CI), contact quotient perturbation(CQP), contact index perturbation(CIP), and the in 82 OSAHS patients and 53 healthy subjects. The voice parameters were analyzed with Dr.Speech software, RESULTS While in normal pronunciation, the Jitter, Shimmer, NNE, CQP and CIP were (1.037±1.493)%, (5.627±1.872)%, (-16.109±1.719)dB, (2.638±0.633)% and (166.789±30.492)% in 22 mild OSAHS patients, (1.578±0.362)%, (8.478±1.635)%, (-11.517±1.614)dB, (6.043±0.936)% and (255.210±91.224)% in 24 moderate OSAHS patients, and (2.138±1.384)%, (14.888±4.089)%, (-7.677±2.151)dB, (11.749±7.164)% and (431.233±259.266)%in 36 severe OSAHS patients respectively. They were all higher than those in 53 normal subjects as (0.517±0.303)%, (3.299±2.196)%, (-21.933±5.477)dB, (1.322±0.942)% and (58.834±131.849)%. The regularity of vocal fold vibration in all patients with OSAHS was seriously out of whack. EGG waveform was irregular. CONCLUSION The OSAHS patients have structural changes in their upper airway, it will cause non-physiological breathing and lead dry of the vocal cord mucosa and weak elasticity. Their EGG parameters will get higher and vibration will be irregular seriously. We should pay attention to the voice qualities of the OSAHS patients and let them receive treatment as early as possible.

Objective To explore the clinic value of the vocal acoustics on voice evaluation in larynx leukoplakia pa?tients. Methods Dr. Speech software was used to perform voice acoustic analysis and deduce EGG parameters in 48 sub?jects with larynx leukoplakia and 50 normal subjects. Voice acoustic analysis parameters (Jitter, Shimmer, NNE, HNR, SNR, MPT), EGG parameters ( EGG-Jitter、EGG-Shimmer、EGG-NNE、EGG-HNR、EGG-SNR, CQP,CIP) and EGG wave?form were compared between two groups. Results For voice acoustic analysis, Jitter, Shimmer, NNE in larynx leukoplakia group were higher than those in normal group while HNR, SNR in larynx leukoplakia group were lower than those of normal group. What’s more,MPT in larynx leukoplakia group was obviously shorter than that in normal group with, statistically sig?nificant difference (P<0.05). For EGG analysis, EGG-Jitter, EGG-Shimmer, EGG-NNE were higher in larynx leukoplakia group than those in normal group with significant difference (P<0.05). EGG-HNR and EGG-SNR in larynx leukoplakia group were lower than those in normal group. Furthermore, CQP and CIP in larynx leukoplakia group were higher than those normal group with statistically significant difference (P<0.05). Most patients’(72.9%) EGG waveform showed gradually ac?celerate phase velocity and fast close phase, which represent a spike-like shape. Conclusion Voice acoustic analysis com?bined with EGG provide objective indicators to assess degree of hoarseness, and to provide sonic evidences for prevention, recurrence, assessment and pronunciation correction of the larynx leukoplakia.

Objective To review the outcome of coronary artery bypass grafting (CABG) using left internal thoracic artery (LITA) grafts in these patients aged more than 70 years old.Methods 1471 patients aged more than 70 years old[mean (73.3 ± 3.9) years] from July 2010 through August 2012,who underwent CABG in Anzhen hospital,form the cohort of this study.Among them,1395 cases underwent off-pump CABG,while 76 cases underwent on-pump CABG which includes onpump beating heart CABG in 12 cases.The average number of the grafts is 3.12 ±0.68.All of the patients were divided into two groups on base of the graft:Group A:only saphenous vein graft was used in 564 cases; Group B:The left internal thoracic artery to the left anterior descending artery was used in 907 cases,which also include total arterial grafting,facilitated by the use of the radial artery,right gastroepiploic artery was operated in 42 cases,beside these artery grafts,saphenous vein graft was used to anastomosis with other vessels.Results Operative mortality was 2.12％ in group A and 2.09％ in group B.There was no significance between the 2 groups.The volume of blood drainage was larger in group B than that in group A.At the same time,there was no significance in the incidence rate of second thoractomy,malignant arrhythmia,stroke,poor wound healing,and usage of IABP between the 2 groups.Conclusion It did not increase the mortality and morbidity of serious complications using the left internal thoracic artery to the left anterior descending artery in those elderly patients aged more than 70 years old during the CABG operation.With consideration of the obvious advantages in the long term patency,LITA was proposed to be used in CABG even in those age ＞ 70 patients.

OBJECTIVETo investigate the role of N-Methyl-D-aspartic acid (NMDA)-type glutamate receptors in the central nucleus of the amygdale (CeA) in food and water intake.

METHODSMale Sprague-Dawley rats with stainless steel cannulae implanted unilaterally into the CeA were used. The prototypic NMDA receptor agonist NMDA, or the selective NMDA receptor antagonist D(-)-2-amino-5-phosphonopentanoic acid (D-AP-5) was microinjected into the CeA of satiated and euhydrated rats.

RESULTSIntra-CeA injection of 8.50, 17.00, or 34.00 nmol NMDA did not alter food intake but significantly increased water intake 0-1 h after the injection (F(3,32)=3.191, P=0.037) independent of food intake. Without affecting the food intake, injection of 6.34, 12.70, or 25.40 nmol D-AP-5 into the CeA significantly decreased water intake 0-1 h after the injection (F(3,28)=3.118, P=0.042) independent of food intake.

CONCLUSIONNMDA receptors in the CeA may participate in the control of water intake rather than food intake.
