Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).

Invasive angiomyxoma（AAM） is characterized by unclear boundaries, non enveloped glial growth, high recurrence rate, and belongs to a benign tumor, but it is invasive and grows slowly. A patient with recurrent left vestibular invasive angiomyxoma was admitted to the Otorhinolaryngology ward of Beijing Traditional Chinese Medicine Hospital Affiliated with Capital Medical University. The patient underwent two repeated surgeries and underwent a combined internal and external nasal approach for the removal of the nasal vestibular angiomyxoma. The patient recovered well after the surgery and has not recurred since follow-up.

Epilepsy affects over 50 million people worldwide. Drug-resistant epilepsy (DRE) accounts for up to a third of these cases, and neuro-inflammation is thought to play a role in such cases. Despite being a long-debated issue in the field of DRE, the mechanisms underlying neuroinflammation have yet to be fully elucidated. The pro-inflammatory microenvironment within the brain tissue of people with DRE has been probed using single-cell multimodal transcriptomics. Evidence suggests that inflammatory cells and pro-inflammatory cytokines in the nervous system can lead to extensive biochemical changes, such as connexin hemichannel excitability and disruption of neurotransmitter homeostasis. The presence of inflammation may give rise to neuronal network abnormalities that suppress endogenous antiepileptic systems. We focus on the role of neuroinflammation and brain network anomalies in DRE from multiple perspectives to identify critical points for clinical application. We hope to provide an insightful overview to advance the quest for better DRE treatments.

Objective To investigate the risk factors of in-hospital mortality and establish a risk prediction model for patients receiving venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods We retrospectively collected the data of 302 patients receiving VA-ECMO in ICU of 3 hospitals in Guangdong Province between January,2015 and January,2022 using a convenience sampling method.The patients were divided into a derivation cohort(201 cases)and a validation cohort(101 cases).Univariate and multivariate logistic regression analyses were used to analyze the risk factors for in-hospital death of these patients,based on which a risk prediction model was established in the form of a nomogram.The receiver operator characteristic(ROC)curve,calibration curve and clinical decision curve were used to evaluate the discrimination ability,calibration and clinical validity of this model.Results The in-hospital mortality risk prediction model was established based the risk factors including hypertension(OR=3.694,95%CI:1.582-8.621),continuous renal replacement therapy(OR=9.661,95%CI:4.103-22.745),elevated Na2+ level(OR=1.048,95%CI:1.003-1.095)and increased hemoglobin level(OR=0.987,95%CI:0.977-0.998).In the derivation cohort,the area under the ROC curve(AUC)of this model was 0.829(95%CI:0.770-0.889),greater than those of the 4 single factors(all AUC<0.800),APACHE Ⅱ Score(AUC=0.777,95%CI:0.714-0.840)and the SOFA Score(AUC=0.721,95%CI:0.647-0.796).The results of internal validation showed that the AUC of the model was 0.774(95%CI:0.679-0.869),and the goodness of fit test showed a good fitting of this model(χ2=4.629,P>0.05).Conclusion The risk prediction model for in-hospital mortality of patients on VA-ECMO has good differentiation,calibration and clinical effectiveness and outperforms the commonly used disease severity scoring system,and thus can be used for assessing disease severity and prognostic risk level in critically ill patients.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective:To explore the recovery of abdominal function and and satisfaction rate in patients who received lower abdominal skin flap repair of extensive soft tissue defects in the limbs based on three-dimensional computed tomography angiography(3D-CTA) technology.Methods:A retrospective study was performed to analyze clinical data from patients with extensive skin and soft tissue defects in the limbs, who were admitted to Shandong Provincial Third Hospital between March 2017 and February 2022. Patients were categorized into two groups: the superficial inferior epigastric artery (SIEA) group and the deep inferior epigastric perforator (DIEP) group, with SIEA flaps and DIEP flaps utilized respectively for tissue defect repair. Based on 3D-CTA imaging, the distribution range and vessel diameters of bilateral SIEA, superficial inferior epigastric veins (SIEV), and DIEP were delineated, facilitating the design and harvest of SIEA and DIEP flaps. Comparisons were drawn between preoperative 3D-CTA findings on the course and distribution of SIEA and SIEV, and intraoperative anatomical observations. In addition, the concordance between vessel diameters and pedicle lengths determined via preoperative 3D-CTA and intraoperative measurements was assessed. The flap survival, wound healing and surveyed patients’ satisfaction with wound repair were analyzed. A customized evaluation scale was utilized to assess abdominal contour one year post-surgery, scoring from 5 to 25, with higher scores indicating better outcomes. The abdominal health module of the BREAST-Q scale evaluated patients’ satisfaction with abdominal function preoperatively, three months postoperatively, and one year postoperatively, scoring from 20 to 100, with increasing scores indicating greater satisfaction. The measurement data that conform to the normal distribution were expressed as Mean±SD, and the comparison between the two groups was performed using independent samples t-test. The comparison were conducted at multiple time points, repeated measures analysis of variance was performed, and for the comparison of scores within the group, paired t-test was applied. Results:A total of 21 patients were included, 3 males and 18 females, with an age range of 21 to 60 years and a mean age of 41 years. The range of skin and soft tissue defects was from 10.0 cm × 5.0 cm to 22.0 cm × 14.0 cm, and the range of skin flap harvesting was from 11.0 cm × 6.0 cm to 23.0 cm × 15.0 cm. There were 11 cases in the SIEA group and 10 cases in the DIEP group. Preoperative 3D-CTA examination showed that the course and distribution of SIEA and SIEV were consistent with intraoperative anatomical observations. There was no statistically significant difference in the comparison of vessel diameters, pedicle lengths, and actual measurements between preoperative 3D-CTA examination and intraoperative measurements (all P > 0.05). No flap necrosis occurred postoperatively, wound healing was uneventful in all cases. At 1 year postoperatively, there was no statistically significant difference in abdominal contour scores between the SIEA and DIEP groups [(21.96±3.51) points vs. (21.62±3.17) points, P > 0.05]. Comparison of preoperative abdominal function satisfaction scores between the SIEA and DIEP groups showed no statistically significant difference [(87.56 ± 5.70) points vs. (85.79 ± 6.33) points, P > 0.05]. However, at 3 months and 1 year postoperatively, the SIEA group had higher scores than the DIEP group [at 3 months postoperatively, (77.62 ± 7.68) points vs. (65.21 ± 8.27) points; at 1 year postoperatively, (86.93 ± 5.65) points vs. (77.59 ± 5.92) points; both P < 0.01], indicating higher abdominal function satisfaction of the SIEA group postoperatively. The scores of both the SIEA and DIEP groups decreased at 3 months postoperatively compared to preoperative scores (both P < 0.01). At 1 year postoperatively, the score of the SIEA group was similar to preoperative levels, with no statistically significant difference ( P > 0.05), while the score of the DIEP group remained lower than preoperative levels ( P < 0.01). Conclusion:Reconstruction of extensive skin and soft tissue defects in the limbs using SIEA flaps, without injury to the deep tissues of the abdominal wall, allows for near-complete restoration of abdominal function and appearance to preoperative levels, with minimal impact on the donor site. Preoperative 3D-CTA reveals the anatomical variations in the vascular supply of SIEA flaps among individuals, achieving comparable wound repair outcomes to other lower abdominal flaps.
