Numerous research conducted in recent years has revealed that gut microbial dysbiosis, such as modifications in composition and activity, might influence lung tissue homeostasis through specific pathways, thereby promoting susceptibility to lung diseases. The development and progression of lung cancer, as well as the effectiveness of immunotherapy are closely associated with gut flora and metabolites, which influence immunological and inflammatory responses. During abnormal proliferation, non-small cell lung cancer cells acquire more substances and energy by altering their own metabolic pathways. Glucose and amino acid metabolism reprogramming provide tumor cells with abundant ATP, carbon, and nitrogen sources, respectively, providing optimal conditions for tumor cell proliferation, invasion, and immune escape. This article reviews the relationship of immune response with gut flora and metabolic reprogramming in non-small cell lung cancer, and discusses the potential mechanisms by which gut flora and metabolic reprogramming affect the occurrence, development, and immunotherapy of non-small cell lung cancer, in order to provide new ideas for precision treatment of lung cancer patients.

BACKGROUND AND OBJECTIVE: Hypertension (HT) and atrial fibrillation (AF) are highly prevalent cardiovascular conditions that frequently coexist. Coronary artery disease (CAD) is a major global cause of mortality. The co-occurrence of HT, AF, and CAD presents significant management challenges. This study aims to explore the clinical characteristics and risk factors associated with CAD in patients with HT and persistent AF (HT-AF). METHODS: In this retrospective cross-sectional study, data were collected from 384 hospitalized HT-AF patients at the People's Liberation Army General Hospital between January 2010 and December 2019. CAD diagnosis was confirmed by coronary angiography or computed tomography angiography. Clinical characteristics and comorbidities were compared between patients with and without CAD. Multivariate logistic regression analyses were performed to identify independent risk factors associated with CAD development. RESULTS: The prevalence of CAD among HT-AF patients was 66.41% (255/384). Cardiovascular complications, particularly heart failure (44.7% vs 25.6%, P < 0.05), were significantly more prevalent in the CAD group than in the non-CAD group. Only age was identified as an independent risk factor for CAD (adjusted OR: 1.047; 95% CI: 1.022-1.073; P = 0.000). Of all HT-AF patients, 54.7% had a CHA2DS2-VASc score of ≥4, indicating high stroke risk. There was a slightly higher anticoagulant usage rate in the CAD group than those without CAD (8.6% vs 4.7%, P = 0.157), and the overall anticoagulant usage remained low. CONCLUSION: There is a high prevalence of CAD among hospitalized HT-AF patients, among whom age is the sole independent risk factor for CAD. Despite a high stroke risk, the utilization of oral anticoagulants is alarmingly low.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.

Objective To observe the alterations in functional complexity of brain regions in autism spectrum disorder(ASD)patients and correlations with the predicted brain age.Methods Open brain resting-state functional MRI(rs-MRI)data of 93 ASD patients and 96 typically developing adolescents(healthy subjects)were downloaded.The functional complexity in brain regions were extracted with self-developed virtual digital brain software,and the alterations in functional complexity of brain regions in ASD patients and correlations with their ages were analyzed.Two networks were prospectively trained with data of 65 ASD patients and 67 healthy subjects as the training set to predict brain age,and the results were evaluated,and the predicting errors were compared using test set,i.e.the other 28 ASD patients and 29 healthy subjects.Results Compared to healthy subjects,on the basis of anatomical automatic labeling(AAL)atlas,ASD patients exhibited significantly reduced functional complexity based on Shannon entropy in the left precuneus,left cuneus and right parahippocampal gyrus.Conversely,functional complexity of ASD patients based on permutation entropy significantly increased in the left cuneus and right cerebellar Crus Ⅱ region.The left hippocampus showed reduced functional complexity based on Pearson correlation coefficient,while the left middle temporal gyrus showed increased functional complexity based on Pearson correlation coefficient.The functional complexity in brain regions of ASD patients were not closely correlated with ages(all|r|<0.4).According to the trained fully connected network,the predicted brain ages of ASD patients and healthy subjects in test set were all lower than their physiological ages,but no significant difference was found between the prediction errors of ASD patients and healthy subjects(P=0.283).Conclusion Functional complexity changed in some brain region functions in ASD patients.The predicted brain ages of ASD patients based on the obtained fully connected network were on the low side,but not obviously affected by the alterations of functional complexity in brain regions.

Objective:To explore the characteristics of drug-induced liver injury induced by acetaminophen (APAP) in children, and to clarify the mechanism of improving APAP liver injury in children on targeting MCJ.Methods:The C57BL/6 young and adult mice and mouse liver parenchymal AML-12 cells were used in the prospective study. Forty C57BL/6 young mice of 3 to 4 weeks and 40 C57BL/6 adult mice of 6 to 8 weeks were randomly divided into 5 groups (control 0 h group, APAP 3 h group, APAP 6 h group, APAP 12 h group, APAP 24 h group), 8 rats in each group and intraperitoneally injected with APAP (300 mg/kg) to replicate drug-induced liver injury (DILI) model. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. Hematoxylin-eosin staining (H&E) staining was used to observe the pathological change of liver tissue. The oxidative damage indexes lactate dehydrogenase (LDH), malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD) of liver tissue homogenate were detected. The expression of MCJ protein was detected by Western blot. Mouse liver parenchymal AML-12 cells were transfected with MCJ interference sequence and APAP to construct hepatocyte injury model. Hepatocyte viability, LDH and SOD levels were measured.Results:As shown in the animals results, after 3 h of APAP administration, ALT and AST levels were increased significantly in young mice, compared with adult mice: (105.25 ± 18.38) U/L vs. (37.38 ± 15.75) U/L, (87.38 ± 30.68) U/L vs. (28.50 ± 19.44)U/L, which suggested that the time liver necrosis occurred in young mice was earlier than that of adult mice. Moreover, the levels of LDH and MDA were significantly increased, while GSH and SOD were significantly decreased after 3 h of APAP in young mice, compared with adult mice, (1 231.38 ± 183.94) U/L vs. (810.50 ± 190.64) U/L, (19.63 ± 3.58) nmol/mg vs. (16.50 ± 3.51) nmol/mg, (39.75 ± 4.62) nmol/mg vs. (53.63 ± 13.07) nmol/mg, (51.38 ± 6.37)% vs. (63.25 ± 9.13)% ( P<0.01), and the levels of MCJ protein were significantly increased. After MCJ knockdown, hepatocyte viability and LDH, SOD levels of mouse liver parenchymal AML-12 cells were significantly improved compared with APAP model group ( P<0.01). Conclusions:APAP liver injury was more common in young mice than in adult mice. Knockdown MCJ expression may ameliorate APAP liver injury in young mice. MCJ may serve as a target for early intervention of APAP liver injury in children, which provide new therapeutic targets and strategies for APAP liver injury in children.

Foodborne pathogens are one of the major factors leading to food safety issues, causing harm to the national economy and people's livelihood. Achieving rapid detection of foodborne pathogens is currently a key strategy for preventing and controlling foodborne diseases. Antibodies naturally possess high specificity and sensitivity, serving as preferred tools for specific recognition of foodborne pathogens. We list the main methods for detecting foodborne pathogens, introduce the evolution and development of polyclonal antibodies, monoclonal antibodies, and genetically engineered antibodies, and review the application of different antibody technologies in the rapid detection of foodborne pathogens. Furthermore, we recognize that the combination of antibody technology and other foodborne pathogen detection methods is currently a reliable means to improve detection performance. Finally, we elaborate on the existing limitations of different antibodies and summarize the current research status and potential issues, aiming to provide a theoretical basis and practical ideas for the development of rapid detection of foodborne pathogens.
