Acute lung injury (ALI) is a severe disease caused by viral infection that triggers an uncontrolled inflammatory response. This study investigated the capacity of jasurolignoside (JO), a natural compound, to bind to Toll-like receptor 4 (TLR4) and treat ALI. The anti-inflammatory properties of JO were evaluated in vitro through Western blotting, enzyme-linked immunosorbent assay (ELISA), immunofluorescence staining, and co-immunoprecipitation. The investigation utilized a lipopolysaccharide (LPS)-induced ALI animal model to examine the therapeutic efficacy and mechanism of JO in vivo. JO attenuated inflammatory symptoms in infected cells and tissues by modulating the NOD-like receptor family pyrin domain containing protein 3 (NLRP3) inflammasome and the nuclear factor κB (NF-κB)/mitogen-activated protein kinase (MAPK) pathway. Molecular docking simulations revealed JO binding to TLR4 active sites, confirmed by cellular thermal shift assay. Surface plasmon resonance (SPR) demonstrated direct interaction between JO and TLR4 with a Kd value of 35.1 μmol·L^-1. Moreover, JO inhibited tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 secretion and reduced leukocyte, neutrophil, lymphocyte, and macrophage infiltration in ALI-affected mice. JO also enhanced lung function and reduced ALI-related mortality. Immunohistochemical staining demonstrated JO's ability to suppress TLR4 expression in ALI-affected mouse lung tissue. This study establishes that JO can bind to TLR4 and effectively treat ALI, indicating its potential as a therapeutic agent for clinical applications.

Objective To evaluate the effect of endoscopic laryngeal mask on perioperative airway management and postoperative recovery in patients undergoing gastric endoscopic submucosal dissection(ESD).Methods Ninety patients,aged 18-64 years,BMI 18-25 kg/m2,ASA physical statusⅠorⅡ,who underwent elective gastric ESD were randomly divided into two groups:the endoscopic laryngeal mask group(group E)and the endotracheal tube group(group C),45 patients in each group.After induction of general anesthesia,group E received endoscopic laryngeal mask airway ventilation,and the endoscope was inserted through the endoscopic channel of the laryngeal mask,group C received tracheal intubation,and the endoscopy was inserted through the mouth.The successful time and one-time success rate of intubation,and the insertion time and withdrawal rate of endoscopy were recorded.The operative time,extubation time and PACU residence time were recorded.HR,MAP were recorded when the patient entered the room(T0),at the time of intubating(T1),inserting gastroscopy(T2),exiting gastroscopy(T3),extubation(T4),and leaving PACU(T5).The average airway pressure and peak airway pressure at T1-T3 were recorded.The airway sealing pressure and endoscopic view grading system(EVGS)grading of group E were recorded before and after changing the position,and at the end of surgery.The adverse reactions and the satisfaction of anesthesiologists and gastroenterologists were recorded.Results Compared with T0,HR and MAP were significantly increased at T1 and T4 between the two groups(P＜0.05).Compared with group C,the suc-cessful time of intubation,the extubation time,and PACU residence time were significantly shortened,HR and MAP were significantly decreased at T1 and T4,the incidence of choking cough during extubation,post-operative pharyngeal pain,and hoarseness were significantly decreased(P＜0.05).There were no signifi-cant differences in the one-time success rate of intubation,the insertion time and withdrawal rate of endosco-py between the two groups.Endoscopic laryngeal mask showed good sealing and alignment in group E.Conclusion Endoscopic laryngeal mask could shorten the success time of establishment of artificial airway in patients with gastric ESD,without interfering with digestive endoscopy operations,shorten extubation time and PACU retention time,maintain intraoperative hemodynamic stability,and reduce adverse reactions.

Outpatient service is a direct reflection of a hospital′s medical level and service efficiency.In February 2024, a tertiary hospital sorted out the existing problems in outpatient services, and constructed a digital intelligent service mode for outpatient services based on the theory of ubiquitous learning, including theoretical foundation layer, data foundation layer, patient profile layer, knowledge fusion layer, and application layer. Based on this mode, the hospital integrated existing outpatient data and knowledge resources using technologies such as artificial intelligence, big data, and knowledge organization, and created multiple application services such as " precision plus", full process self-service guidance, " one code pass" for elderly patients, and one-stop inspection and examination appointments, forming a digital intelligent service ecosystem for outpatient services and providing patients with accurate, efficient, and convenient outpatient services. As of November 2024, the relevant application services had provided accurate online booking services for 90 000 patients, accurate appointment services for 21 000 patients, and completed the " One Code Pass" service for 107 000 elderly patients, achieving good results and providing references for other hospitals to optimize outpatient services.

Objective:To evaluate the efficacy and safety of programmed death 1 (PD-1), programmed death ligand 1 (PD-L1) immune checkpoint inhibitor (ICI) monotherapy for brain metastasis in advanced non-small cell lung cancer (NSCLC), and to explore the timing of immunomonotherapy and the application of hormone on the efficacy of ICI.Methods:By searching literature in CNKI, Wanfang, VIP, PubMed, CBM, Embase, Cochrane Library and Web of Science databases, the advanced NSCLC patients with brain metastasis who received ICI treatment were identified, including patients with symptomatic brain metastasis who had received hormone therapy or brain surgery or radiotherapy. Meta-analysis was performed on the collected data to evaluate the systemic objective response rate (sORR) and intracerebral tumor objective response rate (iORR), the iORR of whether ICI monotherapy was first-line therapy, and the iORR of whether hormone was used were evaluated, and the incidence of adverse reactions was evaluated.Results:Fifteen studies were finally included, with a total of 4 033 patients, including 917 patients with brain metastasis. The iORR of immunomonotherapy was 26% (95% CI 19%-34%) and the sORR was 28% (95% CI 18%-40%). The iORR of first-line immunomonotherapy was 49% (95% CI 39%-58%). The iORR of symptomatic patients with hormone therapy and asymptomatic patients without hormone therapy was 26% (95% CI 20%-33%) and 19% (95% CI 16%-22%), respectively. The overall incidence of grade 3-4 adverse reactions was 14% (95% CI 11%-17%). Conclusions:The efficacy of ICI monotherapy in the first-line treatment of PD-L1-positive NSCLC patients with brain metastasis is better than that in the subsequent line therapy, and the application of hormone does not affect the efficacy of ICI. ICI monotherapy in the treatment of advanced NSCLC patients with brain metastasis is safe.

Objective:To investigate the relationship between the changes of inflammatory cytokine levels and prognosis of patients with critical coronavirus disease 2019 (COVID-19) undergoing invasive mechanical ventilation (IMV).Methods:A retrospective study was conducted. The clinical date of critical COVID-19 patients undergoing IMV who were hospitalized in Wuhan Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from February 4th to March 25th in 2020 were collected. At the same time, the inflammatory cytokine levels including interleukins (IL-2, IL-4, IL-6, IL-10) and tumor necrosis factor-α (TNF-α) at 48 hours before IMV and 48 hours after IMV of all the patients, as well as the 48 hours after weaning or right before death were recorded. Multivariate unconditional Logistic regression analysis was used to screen the independent risk factors of death during hospitalization.Results:Among the 43 patients, 13 patients improved and 30 died. Compared with the survival group, the patients in the non-survival group were older (years old: 67.6±7.3 vs. 58.5±11.9, P < 0.05), with higher rates of hypertension, diabetes and coronary heart disease (53.3% vs. 15.4%, 63.3% vs. 23.1%, 26.7% vs. 0%, all P < 0.05), and the time from onset to admission to hospital, admission to ICU and IMV were longer (days: it was 9.17±5.00 vs. 5.07±2.49, 17.10±7.11 vs. 12.23±5.05, and 17.90±7.46 vs. 12.61±5.60, respectively, all P < 0.05). The IL-6 and TNF-α levels on 48 hours after IMV in the non-survival patients increased significantly as compared with those before 48 hours and the surviving patients. Especially, the IL-6 levels increased significantly as compared with those at 48 hours after IMV and 48 hours after weaning in the surviving patients [ng/L: 800.00 (194.25, 2 000.00) vs. 22.03 (6.66, 28.21), 3 204.00 (1 264.88, 5 000.00) vs. 5.00 (3.98, 12.27), both P < 0.01]. The IL-10 level before death in the non-survival patients increased significantly as compared with that at 48 hours after weaning in the surviving patients [ng/L: 55.89 (26.07, 100.14) vs. 3.53 (2.76, 12.36), P < 0.05]. There were no significant differences in the levels of IL-2 and IL-4 between the two groups at every time point. The variables of age, basic diseases, the IL-6 level after IMV were included in the multivariate unconditional Logistic regression analysis, which showed that age [odds ratio ( OR) = 0.821, 95% confidence interval (95% CI) was 0.695-0.968], hypertension ( OR = 0.027, 95% CI was 0.002-0.378), diabetes mellitus ( OR = 0.054, 95% CI was 0.005-0.611), coronary heart disease ( OR = 0.042, 95% CI was 0.002-0.968) and the IL-6 level after IMV ( OR = 0.902, 95% CI was 0.819-0.994) were independent risk factors for death during hospitalization in patients with critical COVID-19 undergoing IMV (all P < 0.05). Conclusions:The levels of inflammatory cytokine including IL-6, IL-10, and TNF-α increased significantly with aggravation in critical COVID-19 patients undergoing IMV, especially IL-6. IL-6 was an independent risk factor for death of critical COVID-19 patients undergoing IMV.

Objective To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China. Methods The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient′s stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed. Results (1) The total number of hospitalized patients with stageⅠa2 toⅡa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01). The constituent ratio of patients aged 35 years or younger was significantly greater during 2004—2010 than that during 2011—2016 [12.6% (820/6 484) and 8.5% (1 068/12 557), respectively; χ2=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stageⅠ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05). Conclusions The trend in proportion among hospitalized patients for stageⅠa2 toⅡa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type. In terms of the postoperative pathological risk factors, the rate of surgical margin involvement and depth of stromal invasion>1/2 in young women with cervical cancer are lower than in middle-aged and elderly women.
