Objective:To evaluate the safety and efficacy of combined inflatable mediastinoscopy with laparoscopy guided by the concept of “reduced field and port” during esophagectomy for esophageal cancer.Methods:This is a retrospective cohort study. The clinical data of 497 patients with esophageal squamous cell carcinoma who underwent minimally invasive esophagectomy at the Center of Minimally Invasive Thoracic Surgery, the Second Affiliated Hospital of Naval Medical University, between January 2017 and December 2024 were retrospectively analyzed. There were 416 male and 81 female patients, with an age of (68.3±8.0) years (range: 44 to 89 years). Patients were divided into the traditional video-assisted thoracoscopic surgery group (Group A, n=354) and the combined inflatable mediastinoscopy with laparoscopic surgery group(Group B, n=143) based on the surgical approach. Furthermore, Group B was subdivided into the multiport laparoscopic group (Group B1, n=81) and the single-incision laparoscopic surgery plus one port group (Group B2, n=62). Perioperative indicators and postoperative survival differences were compared between the groups. Inter-group comparisons were performed using the independent sample t-test, χ2 test, or Fisher′s exact probability test. Survival curves were plotted using the Kaplan-Meier method, and the Log-rank test was used to analyze the survival differences between groups. Results:Compared with Group A, Group B demonstrated a significantly shorter operative time ((181.8±11.4) minutes vs. (196.7±8.1)minutes, t=16.09, P<0.01), a lower incidence of postoperative pulmonary complications (8.4% (12/143) vs. 17.8% (63/354), χ2=6.27, P=0.012), lower perioperative mortality (0 vs. 3.1%(11/354), P=0.039), and a shorter postoperative hospital stay ((16.2±2.2)days vs. (18.9±4.1)days, t=8.56, P<0.01). There was no significant difference in the anastomotic leak rate, number of lymph nodes dissected, or intraoperative blood loss between the two groups (all P>0.05). Overall survival time and recurrence-free survival time showed no significant difference between the two groups (all P>0.05). Subgroup analysis revealed no significant differences in perioperative indicators or postoperative complication rates between Group B1 and Group B2. Conclusions:Compared with traditional thoracoscopic combined with laparoscopic surgery, inflatable mediastinoscopy offered advantages in terms of lower postoperative pulmonary complication rates, shorter operative time, reduced postoperative hospital stay, and lower perioperative mortality. The “reduced field and port” concept could further minimize surgical trauma during the transmediastinal approach for esophagectomy while ensuring surgical safety and efficacy.

Background: Epimedii Folium, first recorded in the Shennong’s Classic of Materia Medica (Shen Nong Ben Cao Jing), is a traditional Chinese medicine (TCM) known for its effects of “benefiting Qi and strengthening the heart.” Icariside II (ICS II) is one of the main active components of Epimedii Folium, possessing cardiovascular protective and anti-inflammatory properties. However, the potential mechanisms of ICS II on myocardial ischemia (MI) remain unclear. Objective: The aim of the study was to investigate the effects and preliminary molecular mechanisms of ICS II in treating isoproterenolinduced MI in rats. Methods: A rat model of MI was established by subcutaneous injection of isoproterenol. Electrocardiography, echocardiography, myocardial enzymes analysis, heart weight index, triphenyltetrazolium chloride staining, histopathology, TUNEL staining, RT-qPCR, and Western blot were employed to evaluate the effects and preliminary molecular mechanisms of ICS II on MI rats. Results: Pharmacodynamic studies suggested that ICS II inhibited ST-segment elevation in electrocardiograms, improved cardiac function, reduced heart weight index and myocardial enzyme levels, decreased myocardial infarct size, alleviated cardiac histological damage, and inhibited apoptosis, thereby exerting cardioprotective effects in MI rats. Further studies revealed that ICS II may partially inhibit the expression of NLRP3/Caspase-1 axis-related targets at both protein and mRNA levels. Conclusions: Our findings indicate that ICS II exerts anti-MI effects, and its preliminary molecular mechanisms may be related to inhibiting the activation of the NLRP3/Caspase-1 axis to alleviate inflammatory responses.

Objective:To investigate the early clinical characteristics of elderly patients with severe burns and the risk factors on prognosis.Methods:This study was a retrospective case series study. Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Objective To investigate the application value of dual-layer spectral computed tomography(DLCT)45 keV single energy image in follow up after transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC).Methods The DLCT images of 60 patients with HCC after TACE treatment were analyzed retrospectively.The CT value and standard deviation(SD)value of the lesion region of interest(ROI)and surrounding normal liver parenchyma on two kinds of images with 45 keV energy spectrum CT and 120 kVp conventional CT were measured respectively,then the contrast-to-noise ratio(CNR)between the lesions and surrounding normal liver parenchyma was calculated,and their differences were compared.The image quality of the two kinds of images was scored subjectively with the 3-point method,and the patients were divided into different groups according to the enhance-ment degree and tumor staining.The receiver operating characteristic(ROC)curve was also drawn.Results(1)There was no signif-icant difference in CNR between arterial phase,portal phase,and delayed phase of 120 kVp conventional CT(Hc=1.128,P>0.05).The CNR of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,with a statistically significant difference(Z=5.060,P<0.05).(2)The subjective score of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,and the difference was statistically significant(Z=5.335,P<0.05).ROC curve analysis showed that 45 keV energy spectrum CT had a larger area under the curve(AUC)than 120 kVp conventional CT,and the difference was statistically significant(Z=4.136,P<0.001).Conclusion 45 keV energy spectrum CT image can significantly improve the CNR between tumor and normal liver parenchyma,and it has the better image quality and higher diagnostic efficiency.
