Objective To analyze the influencing factors for postoperative anastomotic leak (AL) in carcinoma of the esophagus and gastroesophageal junction and construct a nomogram predictive model. Methods The patients who underwent radical esophagectomy at Jinling Hospital Affiliated to Nanjing University School of Medicine from January 2018 to June 2020 were included in this study. Relevant variables were screened using univariate and multivariate logistic regression analyses. A nomogram was then developed to predict the risk factors associated with postoperative AL. The predictive performance of the nomogram was validated using the receiver operating characteristic (ROC) curve. Results A total of 468 patients with carcinoma of the esophagus and gastroesophageal junction were included in the study, comprising 354 males and 114 females, with a mean age of (62.8±7.2) years. The tumors were predominantly located in the middle or lower esophagus, and 51 (10.90%) patients experienced postoperative AL. Univariate logistic regression analysis indicated that age, body mass index (BMI), tumor location, preoperative albumin levels, diabetes mellitus, anastomosis technique, anastomosis site, and C-reactive protein (CRP) levels were potentially associated with AL (P<0.05). Multivariate logistic regression analysis identified age, BMI, tumor location, diabetes mellitus, anastomosis technique, and CRP levels as independent risk factors for AL (P<0.05). A nomogram was developed based on the findings from the multivariate logistic regression analysis. The area under the receiver operating characteristic (ROC) curve was 0.803, indicating a strong concordance between the actual observations and the predicted outcomes. Furthermore, decision curve analysis demonstrated that the newly established nomogram holds significant value for clinical decision-making. Conclusion The predictive model for postoperative AL in patients with carcinoma of the esophagus and gastroesophageal junction demonstrates strong predictive validity and is essential for guiding clinical monitoring, early detection, and preventive strategies.

In recent years, robot-assisted esophagectomy has become increasingly widespread, but the esophagogastric anastomosis step remains relatively complex and cumbersome. Currently, commonly used gastrointestinal reconstruction anastomosis techniques include end-to-end anastomosis, end-to-side anastomosis, and side-to-side anastomosis. Depending on the anastomosis method, they can be further divided into manual anastomosis and mechanical anastomosis, with common instruments including circular staplers and linear staplers. In esophageal cancer surgery, the choice of esophagogastric anastomosis technique is typically based on the tumor’s location and size as well as the surgeon’s preference. Each anastomosis technique has its advantages and disadvantages. With continuous improvements in anastomosis techniques and updates in stapling instruments, the incidence of complications after esophagogastric anastomosis has been effectively reduced. However, safely and efficiently completing gastrointestinal reconstruction during surgery remains a significant challenge. Scholars have made extensive explorations in this field, actively proposing and achieving various reconstruction methods, leading to significant progress. This article reviews the research progress of robot-assisted esophagogastric anastomosis techniques from both the anastomosis techniques and methods perspectives.

Malignant pleural effusion (MPE) refers to the accumulation of pleural fluid caused by metastasis from primary pleural malignancies or tumors originating elsewhere. It is associated with a poor prognosis. Current treatment strategies primarily include systemic anti-tumor therapy and local management of MPE based on the primary tumor. Numerous studies have documented diverse approaches for the local control of MPE. This review summarizes recent advances in local treatment strategies for primary tumor-related MPE, highlighting emerging pharmacological agents and innovative techniques.

Prostate cancer (PCa) is globally the most prevalent malignancy in the male genitourinary system, with a continuously ascending incidence in China. For the treatment of localized PCa, radical prostatectomy and radiotherapy have demonstrated effective suppression of the tumor, but with obvious complications that markedly compromise the life quality of the patients. Focal therapy, by targeting the principal tumor foci, can largely reduce the incidence of complications. In this context, irreversible electroporation represents an emerging modality of focal treatment capable of ablating the tumor as thoroughly as possible while sparing such critical structures as the urethra, rectum and neurovascular bundles from thermal damage, and thus offers a promising option for the management of localized PCa. This article presents an overview of the latest advances in the studies of irreversible electroporation.

OBJECTIVE: This study aims to analyze the influence factors of lower urinary tract symptoms (LUTS) in patients receiving radical prostatectomy for prostate cancer, and to explore effective nursing strategy in order to provide a theoretical basis for improving the postoperative quality of life of patients. METHODS: A retrospective study was conducted on 103 elderly male patients who underwent radical prostatectomy for prostate cancer in the Department of Urology at General Hospital of Eastern Theater Command from August 2022 to August 2024. The patients were categorized into two groups based on whether LUTS occurred. Demographic and clinical characteristics, perioperative parameters, follow-up data, and participation in pelvic floor muscle training were analyzed to identify risk factors associated with postoperative LUTS. RESULTS: The incidence of postoperative LUTS in the patients with LUTS before the operation was significantly higher than that in the patients without LUTS before the operation (68.42% vs 32.61%, P=0.001). Additionally, the use of larger catheters (22F) was closely associated with an increased incidence of postoperative LUTS(P<0.01). Pelvic floor exercises demonstrated a significant protective effect, with patients who engaged in pelvic floor exercises exhibiting a lower incidence of postoperative LUTS (38.60% vs 60.87%, P=0.040). Regression analysis further revealed that pelvic floor exercises was the protective factor for postoperative LUTS (OR=0.215, 95%CI: 0.091－0.508, P<0.01). CONCLUSION Preoperative LUTS and catheter size are significant risk factors for the occurrence of postoperative LUTS following radical prostatectomy. Pelvic floor muscle exercise after surgery has a protective effect. Postoperative personalized nursing interventions are necessary for different patients to achieve optimal recovery outcomes.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

AIM:To investigate the effect and mechanism of velvet antler polypeptide(VAP)on premature ovarian failure induced by cisplatin(DDP)in rats.METHODS:Female rats with normal estrous cycle were randomly di-vided into the control,model,and VAP groups,with 10 rats in each group.Premature ovarian failure was induced in the model and VAP groups by intraperitoneal injection of DDP(4 mg·kg-1·d-1)for 20 consecutive days,and the VAP group was treated with VAP(400 mg·kg-1·d-1)for 20 consecutive days.Hematoxylin and eosin(HE)staining was used to ob-serve the morphological manifestations of the ovary,and the number of developing follicles at all levels was counted.En-zyme-linked immunosorbent assay(ELISA)was performed to detect serum estradiol(E2),follicle-stimulating hormone(FSH),and anti-Mullerian hormone(AMH)levels.The levels of glutathione(GSH)and malondialdehyde(MDA)in ovarian tissues were detected by biochemical methods.The level of reactive oxygen species(ROS)in ovarian tissue was detected by the probe labeling method.Prussian blue staining was performed to observe the iron accumulation in ovarian tissue,as well as the ferrous ion(Fe2+)level was detected by Fe2+content analysis kit.Immunohistochemistry and West-ern blot analysis were performed to detect the expressions of solute carrier family 7 member 11(SCL7A11),glutathione peroxidase 4(GPX4),and acyl-CoA synthetase long-chain family member 4(ACSL4)in the ovarian tissue.The fertility of rats was monitored in each group.RESULTS:Compared with control group,the model group showed ovarian atrophy,iron accumulation(P<0.01),reduced development of follicles at all levels and total follicles(P<0.05),increased atretic follicles(P<0.01),reduced litter size(P<0.01),decreased serum E2 and AMH levels(P<0.01),increased FSH levels(P<0.01),decreased GSH level and SCL7A11 and GPX4 protein expression levels in the ovarian tissue(P<0.01),and increased levels of Fe2+,MDA,and ROS and expression levels of ACSL4(P<0.01).Compared with model group,the VAP group had improvement in these aforementioned changes caused by DDP(P<0.01).CONCLUSION:Treatment with VAP can improve ovarian function,maintain normal follicle development,and improve fertility in cisplatin-induced premature ovarian failure rats,and the mechanism may be related to the inhibition of lipid peroxidation and ferroptosis.

Objective:To evaluate the cardiac morphological and functional parameters of patients with persistent atrial fibrillation (per-AF) and paroxysmal atrial fibrillation (PAF) using two-dimensional speckle tracking echocardiography (2D-STE) and real-time three-dimensional echocardiography (RT-3DE), and to explore their predictive value for the occurrence and progression of atrial fibrillation.Methods:A retrospective study was conducted on 30 per-AF patients (per-AF group), 30 PAF patients (PAF group) and 25 non-AF subjects (control group) who underwent echocardiography at Wuhan University People′s Hospital from May 2022 to May 2023. The left/right atrial longitudinal strain of reservoir, conduct and contraction (LASr/RASr, LAScd/RAScd, LASct/RASct), and calculated left atrial stiffness (LASI) were assessed by 2D-STE. Three-dimensional left and right atrial maximum volume index (LAVImax/RAVImax), minimum volume index (LAVImin/RAVImin) and emptying fraction (LAEF/RAEF) were obtained by RT-3DE. Then, patients with atrial fibrillation were divided into the normal LAVI group and enlarged LAVI group, and the differences of atrial strain among each group were compared. ROC curve was used to evaluate the overall diagnostic efficiency and cutoff values of ultrasonic parameters in patients with normal volume of atrial fibrillation. Finally, a multivariate Logistic regression model was established to identify the ultrasonic parameters associated with the occurrence and progression of different types of atrial fibrillation.Results:①Structurally, LAD, RAD and RAVImin in control, PAF and per-AF groups increased gradually, while LAEF and RAEF decreased gradually (all P<0.05). ②In terms of strain, LASr in control, PAF and per-AF groups decreased gradually (all P<0.05); Compared with the control group, LAScd, RASr and RAScd in PAF and per-AF groups were significantly decreased, and LASct and RASct in PAF group were significantly decreased (all P<0.05). ③Compared with the normal LAVI group, the LASr, LAScd and LASct in the enlarged LAVI group were significantly decreased, while LASI was significantly increased (all P<0.05); Compared with control group, the left and right atrial strain parameters in LAVI normal group were decreased, and LASI was increased (all P<0.05). The atrial strain parameter ROC was constructed in all subjects with normal left atrial volume, and RASr was the most sensitive indicator.④Multi-factor Logistic regression analysis showed that LAVImin and RASr were the influence factors of PAF ( OR=1.521, 0.907; 95% CI=1.173-1.972, 0.825-0.998; P=0.002, 0.044), LASr was the influence factor of pre-AF ( OR=0.858, 95% CI=0.802-0.917, P<0.001). Conclusions:2D-STE and RT-3DE can be used to evaluate the structural and functional changes of both atria, especially LAVImin, LASr and RASr, which have certain predictive value for the occurrence and progression of atrial fibrillation.
