Objective:To investigate the predictive value of neutrophil extracellular traps (NETs) on the prognosis of patients with epidermal growth factor receptor (EGFR) wild-type lung adenocarcinoma.Methods:A total of 132 surgical paraffin specimens of EGFR wild-type lung adenocarcinoma diagnosed at the Tumor Hospital Affiliated to Xinjiang Medical University from January 2016 to December 2023 and 12 pairs of cancer and paracancerous fresh tissues from patients with EGFR wild-type lung adenocarcinoma diagnosed in March-July 2024 were collected with their clinical information. Western blotting and immunofluorescence were used to detect the expression levels of citrullinated histone H3 (CitH3) and myeloperoxidase (MPO) in cancerous and paraneoplastic tissues. Immunohistochemistry was used to detect the infiltration of PD-L1, CD4 + T cells and CD8 + T cells in the tumors. The clinical and prognostic correlations between NETs and EGFR wild-type lung adenocarcinoma patients were analyzed. Results:The expression of MPO ( P＜0.001) and CitH3 ( P=0.009) was significantly increased in the tumors compared with the paracancerous tissues. The rate of high expression of NETs in cancer tissues was higher in patients with EGFR wild-type lung adenocarcinoma who were in stage Ⅲ and Ⅳ, with lymph node metastasis, distant metastasis, pleural invasion, high expression of Ki-67, low expression of CD8 + T, and lowered lymphocyte counts when compared to paraneoplastic tissues ( P＜0.05). Patients were stratified based on TNM stage Ⅱb for prognostic analysis. Kaplan-Meier univariate analysis showed that the median overall survival (OS) (stage Ⅰ to Ⅱb: 47 vs 87 months; stage Ⅲ to Ⅳ: 27 months vs not reach) and the median disease-free survival (DFS) (stage Ⅰ to Ⅱb: 42 vs 78 months; stage Ⅲ to Ⅳ: 18 vs 39 months) of patients with high expression of NETs in stage Ⅰ to II b and stage Ⅲ to Ⅳ were lower than those with low expression (stage Ⅰ to Ⅱb: OS, P＜0.001; DFS, P＜0.001; stage Ⅲ to Ⅳ: OS, P=0.001; DFS, P=0.022). The OS (stage Ⅰ to Ⅱb: HR=3.513, 95% CI: 1.966-6.277, P＜0.001; stage Ⅲ to Ⅳ: HR=3.215, 95% CI: 1.324-7.806, P=0.010) and the DFS (stage Ⅰ to Ⅱb: HR=2.478 ,95% CI: 1.396-4.400, P=0.002; stage Ⅲ to Ⅳ: HR=2.248, 95% CI: 1.089-4.638, P=0.028) in the group with high expression of NETs in either stage Ⅰ to Ⅱb or stage Ⅲ to Ⅳ were significantly shorter than those in the group with low expression. Conclusion:The EGFR wild-type lung adenocarcinoma patients with high expression of NETs have relatively shorter DFS and OS, which are independent risk factors for the prognosis of patients with EGFR wild-type lung adenocarcinoma, and are likely to be the potential biomarkers for the diagnosis and treatment of EGFR wild-type lung adenocarcinoma.

OBJECTIVE To study the mechanism of Wenshen Tongdu Recipe in promoting the recovery of motor function in rats with spinal cord injury.METHODS A total of 144 SD rats were randomly divided into sham operation group,model group,predni-sone group,low-dose Wenshen Tongdu Recipe group,medium-dose Wenshen Tongdu Recipe group,high-dose Wenshen Tongdu Recipe group,3BDO group,and 3BDO+Wenshen Tongdu Recipe group(medium dose).The rat spinal cord injury model was estab-lished by modified Allen's method.Intervention began 1 day after modeling,and the drug was administered continuously for 14 days.During the drug administration period,the motor function of the rats in each group was evaluated by Basso-Beattie-Bresnahan(BBB)score and inclined plane test.On the 3rd,7th and 14th days after modeling,the pathological changes of the spinal cord tissues of the rats in each group were observed by HE staining;the expression levels of inflammatory factors IL-1β,IL-6,IL-4 and IL-10 in the serum of the rats in each group were detected by ELISA;the expression of Beclin 1,LC3B and p62 proteins was detected by immu-nohistochemistry;the expression of CD16 and CD206 proteins was detected by immunofluorescence staining;the expression of autoph-agy-related molecules(Beclin 1,LC3B)and Akt/mTOR pathway-related proteins in the spinal cord tissues was detected by Western blot.RESULTS Compared with the model group,the BBB score and angle of the inclined board test of rats in the medium-dose Wenshen Tongdu Recipe group were increased,and the disordered arrangement of spinal cord tissue,spinal cord vacuoles and inflam-matory infiltration were significantly improved,especially on the 14th day.Compared with the sham operation group,the expression levels of serum IL-1β and IL-6 in the model group increased(P<0.01),and the expression levels of IL-4 and IL-10 decreased(P<0.05,P<0.01);compared with the model group,the levels of IL-1β and IL-6 in the Wenshen Tongdu Recipe group were signifi-cantly decreased(P<0.01),and the levels of IL-4 and IL-10 were significantly increased(P<0.05,P<0.01);compared with the Wenshen Tongdu Recipe group,the serum IL-1β and IL-6 concentrations of mice in the 3BDO group increased(P<0.01),and the level of IL-10 decreased(P<0.05).Compared with the sham operation group,the M1/M2 ratio,P62 protein expression,p-Akt/Akt and p-mTOR/mTOR ratios in the spinal cord tissue of the rats in the model group were significantly increased(P<0.05,P<0.01),and the relative protein expression of Beclin1 was decreased(P<0.01);compared with the model group,the M1/M2 ratio,p-Akt/Akt and p-p70S6K/p70S6K ratios in the Wenshen Tongdu Recipe group were significantly decreased(P<0.01).Compared with the model group,the Beclin1 protein level in the 3BDO group was decreased,and the p-Akt/Akt and p-mTOR/mTOR ratios were increased(P<0.05,P<0.01).Compared with the Wenshen Tongdu Recipe group,the M1/M2 ratio in the 3BDO group and the 3BDO+Wen-shen Tongdu Recipe group increased(P<0.01),the positive rates of Beclin1 and LC3B proteins in the 3BDO group decreased signifi-cantly(P<0.01),and the p-p70S6K/p70S6K ratio in the 3BDO+Wenshen Tongdu Recipe group increased significantly(P<0.01).CONCLUSION Wenshen Tongdu Recipe may regulate microglial polarization through Akt/mTOR signaling pathway to acti-vate autophagy,promote the secretion of anti-inflammatory factors,reduce the release of pro-inflammatory factors,alleviate neuroin-flammatory response,and thus promote spinal cord injury repair.

Metabolic dysfunction-associated steatotic liver disease(MASLD)is a chronic liver condition intricately linked to metabolic abnormalities such as obesity,type 2 diabetes,dyslipidemia,and hypertension.The global prevalence of MASLD continues to rise,posing a significant public health challenge.The pathogenesis of MASLD is multifactorial,with the"multiple-hit"hypothesis suggesting that hepatic lipid accumulation,insulin resistance,oxidative stress,gut microbiota dysbiosis,and genetic factors collectively drive disease progression.Currently,clinical management primarily relies on lifestyle interventions;however,there is a lack of targeted pharmacological interventions,and there is an urgent need to investigate novel adjunctive therapeutic strategies.In recent years,probiotics have demonstrated potential value in MASLD treatment due to their capacity to modulate gut microbiota,enhance insulin sensitivity,and reduce liver inflammation.This review systematically examines the pathogenesis of MASLD and the limitations of existing therapeutic approaches,synthesizing the latest evidence of probiotics-assisted therapy for MASLD from the perspectives of animal studies and clinical trials.By analyzing the target mechanisms and molecular pathways of different strains(e.g.,Bifidobacterium,Lactobacillus),this review explores the translational potential of probiotics in MASLD treatment,aiming to provide a theoretical foundation and future research directions.

Objective To discuss the application of mind map in self-management of elderly patients after receiving mitral valve transcatheter edge-to-edge repair(M-TEER).Methods A total of 66 patients,who underwent M-TEER at Nanjing Hospital of Nanjing Medical University from August 2021 to October 2022,were enrolled in this study.Using the envelope concealment method,a total of 66 data analysis samples were included in the analysis.There were 33 patients each in the study group and control group.Routine health education was adopted for the patients of the control group,while the responsible nurse conducted health education for the patients of the study group under the guidance of the mind map that was designed by a multidisciplinary specialized nurses.Results There was a significant difference in postoperative medication compliance between the study group and the control group(P＜0.05),i.e.the degree of compliance,including taking medicine on time,insisting on taking medicine and taking medicine as prescribed,in the study group was obviously higher than that in the control group.The postoperative 6-min walking test,which was regarded as one of the indicators of cardiac functions,in the study group was remarkably better than that in the control group,the difference was statistically significant(P＜0.05).The postoperative quality of life(including daily activity ability,frailty degree,social support,and incidence of hospitalization for heart failure within one year after treatment)in the study group was strikingly better than that in the control group(P＜0.05).Conclusion The use of mind map in self-management of elderly patients after receiving M-TEER can effectively improve the medication compliance of the patients after discharge,improve the quality of life of patients,and reduce the incidence of hospitalization due to heart failure.

Objective:To determine the risk factors for permanent nerve damage (PND) after aortic arch surgery in patients with acute type A aortic dissection (AAAD).Methods:This was a retrospective case-control study. The medical records from patients of both sexes with AAAD, aged > 18 yr, of American Society of Anesthesiologists Physical Status classification IV, who underwent aortic arch surgery in the Second Hospital of Hebei Medical University from December 2018 to December 2023, were collected. The patients were divided into non-PND group and PND group according to whether PND occurred after operation. The preoperative data of patients were collected, including age, gender, body mass index; comorbidities (hypertension, coronary heart disease, diabetes mellitus), history of smoking, history of stroke, and history of cardiovascular surgeries; syncope at onset, preoperative low SpO 2, preoperative low systolic blood pressure, and preoperative low diastolic blood pressure. The intraoperative data included surgical procedure (total aortic arch replacement or half aortic arch replacement), selective antegrade cerebral perfusion during operation, cardiopulmonary bypass (CPB) time, aortic cross-clamp time, post-parallel time, moderate hypothermia circulatory arrest time, nasopharyngeal temperature and rectal temperature during circulatory arrest, and BIS value during circulatory arrest; blood pressure during cardiopulmonary bypass and after restoration of heart beat; the incidence of dysfunction after recovery of heart beat and difficulty in hemostasis after termination of CPB. The aforementioned indicators were analyzed for difference, and the indicators with P<0.05 were included in the multivariate logistic regression analysis. Results:A total of 292 patients were ultimately included, among which 73 developed postoperative PND, resulting in an incidence of 25.0%. The results of multivariate logistic regression analysis showed that age ≥62 yr ( OR=3.783, 95% confidence interval [ CI] 1.513-10.346, P=0.006), preoperative hypertension ( OR=2.230, 95% CI 1.118-4.715, P=0.028), syncope at onset ( OR=3.001, 95% CI 1.343-6.710, P=0.007), BIS value > 14 during circulatory arrest ( OR=2.439, 95% CI 1.249-4.755, P=0.009) and difficult hemostasis after termination of CPB ( OR=3.465, 95% CI 1.758-6.882, P<0.001) were risk factors for PND after surgery. Conclusions:Age ≥ 62 yr, history of hypertension, syncope at onset, BIS value greater than 14 during circulatory arrest and difficulty in hemostasis after termination of CPB are risk factors for PND after aortic arch surgery in patients with AAAD.

Objective:To analyze the epidemiological characteristics of respiratory virus infections in Sichuan from 2017 to 2023, and investigate the changes in detection rates of various viruses in different periods and age groups.Methods:The study included 41 516 patients with acute respiratory infections. Clinical laboratory results of these patients were retrospectively collected to calculate the detection rates of various viruses. The epidemiological characteristics of respiratory virus infections before, during, and after the COVID-19 pandemic, the prevalence of mixed infections, and the detection rates in different seasons and age groups were analyzed.Results:The overall detection rate of respiratory viruses was 23.35% (9 696/41 516), with influenza A virus (8.47%, 3 515/41 516), rhinovirus (7.13%, 2 961/41 516), and influenza B virus (2.04%, 846/41 516) being the most prevalent. The highest detection rate was observed in children aged 0-14 years (48.62%, 1 429/2 939), while the detection rates in young, middle-aged, and elderly individuals were similar [21.00% (1 482/7 057), 22.06% (3 828/17 350), 20.33% (2 685/13 205)]. The detection rate of influenza A virus dropped to 1.35% (253/18 717) during the COVID-19 pandemic, and rebounded to 13.05% (1 560/11 953) after the pandemic. A similar pattern was observed in other viruses such as human metapneumovirus, influenza B virus, coronavirus, and respiratory syncytial virus, with significant reductions during the COVID-19 pandemic and subsequent increases that even exceeded pre-pandemic levels. The detection rates of adenovirus, bocavirus, and rhinovirus gradually decreased over time, while the prevalence of parainfluenza virus remained stable, indicating a less significant impact of COVID-19 on these viruses. Higher detection rates were observed in autumn (28.90%, 2 324/8 041) and winter (26.52%, 4 093/15 433) as compared to that in spring (17.61%, 1 848/10 494) and summer (18.96%, 1 431/7 548), suggesting significant seasonal impacts on virus detection rates ( P<0.001). This study identified 8 666 cases of single-virus infections, 948 double infections, 77 triple infections, and five quadruple infections. Co-infection of bocavirus and rhinovirus was the most common type of double infections (17.41%, 165/948), and 59.60% (565/948) of double infections involved rhinovirus. Conclusions:The overall detection rate of respiratory viruses is higher in autumn and winter than in spring and summer. The prevalence of some respiratory viruses such as influenza viruses decreases during the COVID-19 pandemic. People of different ages can develop multiple infections with rhinovirus being the most common in double infections.

Objective To analyze the main factors affecting early using enteral nutrition and the effect of enteral nutrition within 72 h after burning on outcomes by presenting a retrospective cohort study of 11 years of hospitalization data,to provide evidence for enteral nutrition regimens for severe burn patients.Methods A retrospective study analyzed adult extensive burn patients between January 2009 and December 2020.Patients enrolled in this study who admitted to the burn department within 24 h after burning and with a burned area of more than 30%.Univariate and multiple regression were used to analyze the main factors affecting early using enteral nutrition in patients with severe burn.Non parametric Mann-Whitney U test was used to compare the main influencing factors of enteral nutrition implementation within or after 72 h,as well as the impact on the treatment outcomes such as 28-day survival rate and in hospital survival rate.Results The univariate analysis found that total burn area,full-thickness burn area,burn type,and inhalation injury were the main factors of the time to initation of enteral nutrition in patients with severe burn(P<0.05).Incorporating the above single factors into multiple regression analysis,we found that the main factors affecting enteral nutrition using in patients with severe burn were full-thickness burn area(P=0.017)and inhalation injury(P=0.001).To analysis whether enteral nutrition was started within 72 h after burning,we found that inhalation injury and larger area of full-thickness burn area in patients was the main factors for initiating enteral nutrition.After matching injury situation with pre-injury situation,we found that using enteral nutrition within or after 72 h after injury were no significant differences in the survival rate,28-day survival rate,and positive blood culture rate(P>0.05),but was associated with the lower incidence of bacteria positive in intravenous catheters(P=0.001)and the lower rate of parenteral nutrition treatment used within 7 d after burning(P= 0.001).Conclusions The main factor for influencing early implement enteral nutrition in patients with severe burn were large area of full-thickness burn and inhalation injury.Enteral nutrition using within 72 h after burning reduces the incidence of catheter infection and the use of parenteral nutrition,thereby reducing the risk of treatment in patients with severe burn.

Objective: To examine the changes of depressive and anxiety symptoms in school aged children during home confinement and to identify possible influence of learning and lifestyle behaviors on mental health changes. Methods: The population of this study were obtained from the "Tongji Mental Health Cohort". Two primary schools in Wuhan were selected through cluster sampling and students in grade 2-5 were surveyed. This study was divided into two stages. In the first stage (T1=during home learning), a total of 2 588 valid questionnaires were collected. In the second phase (T2=during school learning), 2 424 children were followed up successfully. Combining the results of the depression and anxiety symptoms of the two surveys of children respectively to classify the children s psychological outcomes. Association between home learning and lifestyle behaviors with the change of psychological symptoms in school aged children were estimated by disordered multi classification Logistic regression. Results: The prevalence of depressive and anxiety symptoms were 28.9% and 21.0% in school aged children at T1, 35.6% and 30.6% at T2, respectively. The aggravation and persistence of depressive and anxiety symptoms in children were partly related to their home learning and lifestyle behaviors. Concentration in class（ OR=0.63，95%CI =0.45-0.89）, frequent interaction with teachers ( OR =0.74, 95% CI = 0.57- 0.95 ), participation in physical exercise at home ( OR =0.60, 95% CI =0.41-0.87) was negatively associated with depressive symptoms in children. Time spent on playing video games ( OR =1.15, 95% CI =1.06-1.24) and fear of infection with coronavirus disease 2019 ( OR =1.83, 95% CI =1.39-2.42) were positively associated with anxiety in children. Boys（ OR=0.70， 0.63 ） were more likely to suffer from depression and anxiety symptoms than girls. Conclusion The prevalence of depressive and anxiety symptoms among school aged children increased when they went back to school after home confinement, suggesting more attention are needed for mental health intervention among school aged children.
