Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.

Hyssopus cuspidatus is an authentic medicinal herb used in Xinjiang， rich in the chemical constituents including flavonoids， phenolic acids and terpenoids. It possesses anti-inflammatory， antioxidant， and immunomodulatory effects. Modern pharmacological studies have demonstrated that H. cuspidatus exerts therapeutic effects on asthma by inhibiting airway inflammatory responses， suppressing airway remodeling， modulating the function of the hypothalamic-pituitary-adrenal axis， and relaxing bronchial smooth muscle. It also demonstrates intervention effects on chronic obstructive pulmonary disease by reducing levels of inflammatory cytokines and regulating immune balance. Additionally， H. cuspidatus can mitigate acute lung injury by inhibiting oxidative stress and intervene in lung cancer by suppressing proliferation and promoting apoptosis of lung cancer cells. In terms of clinical application， compound preparations containing H. cuspidatus， such as Hanchuan zupa granules and Luo’ou kezupa， have demonstrated favorable therapeutic effects on pulmonary diseases including asthma， cough， and pediatric bronchopneumonia. Currently， the research on precise action targets and compound matching rules of H. cuspidatus remains inadequate. Future studies should integrate modern technologies such as metabolomics to conduct in-depth exploration， thereby promoting the modernized development and clinical application of this traditional medicinal herb.

Objective : To explore the role of semaphoring 6d(SEMA6D) in the malignant progression of triple-negative breast cancer(TNBC). Methods : Bioinformatics and Immunohistochemistry(IHC) were used to analyze the expression level of SEMA6D in TNBC and paracancer non-tumor tissues and its relationship with patients′ clinicopathological features. MDA-MB-231 cell line stably knocking down the expression of SEMA6D was constructed, and the effects of SEMA6D on migration and invasion of TNBC cells were investigated by Wound-healing assays and Transwell assays. cBioPortal and GEPIA2 databases were used to screen out the gene negatively associated with it, namely aurora kinase A(AURKA). Bioinformatics and IHC were used to analyze the expression level of AURKA in TNBC and paracancer non-tumor tissues and its relationship with patients' clinicopathological features. Western blot assay was used to analyze the expression of AURKA and the effect of epithelial-mesenchymal transition(EMT) makers Claudin-1, N-cadherin and Vimentin after knocking downSEMA6D. Results: Bioinformatics analysis and IHC results showed that the expression of SEMA6D in TNBC tissues was significantly lower than that in paracancer non-tumor tissues(bothP<0.05). The expression of AURKA in TNBC tissues was significantly higher than that in paracancer non-tumor tissues(bothP<0.05), SEMA6D and AURKA were significantly negatively correlated in TNBC(P<0.01). Both low expression of SEMA6D and high expression of AURKA were positively correlated with tumor size, tumor histological grade, clinical stage and lymph node metastasis in TNBC patients(allP<0.05). The knockdown ofSEMA6Dsignificantly promoted the migration and invasion ability of TNBC cells(bothP<0.01). Western blot results showed that the knockdown ofSEMA6Dupregulated AURKA expression, promoted the expression of N-cadherin and Vimentin, and inhibited the expression of Claudin-1 in tumor cells. Conclusion Down-regulation of SEMA6D expression in TNBC may be involved in the malignant progression of TNBC through up-regulation of AURKA expression and promotion of EMT.

Objective:To investigate the mechanism of miR-218-5p regulating the glycolytic process in human non-small cell lung cancer A549 cells by targeting phosphodiesterase 7A(PDE7A).Methods:A549 cells were routinely cultured,and miR-218-5p mimic,mimic-NC,PDE7A overexpression plasmid(PDE7A-oe)and PDE7A control plasmid(PDE7A-NC)were transfected into A549 cells using Lipo3000,and recorded as the miR-218-5p mimic group,the mimic-NC group,the PDE7A-oe group and the PDE7A-NC group.The transfection efficiency was verified by qPCR assay;the expressions of glycolysis key enzyme proteins were detected by WB assay;the 2-deoxyglucose and lactate contents in A549 cells of each transfection group were detected by glucose assay and lactate production assay;the target binding relationship between miR-218-5p and PDE7A was verified by dual-luciferase reporter gene assay,and the data from the TCGA database were used to analyze the expression level of PDE7A mRNA in lung cancer tissues.Results:miR-218-5p was successfully overexpressed in A549 cells(P<0.01).Overexpression of miR-218-5p significantly inhibited the expressions of PDE7A,HK2,PKM2 proteins(all P<0.01),glucose uptake and lactate production(both P<0.01)in A549 cells.Overexpression of PDE7A significantly promoted the expressions of PDE7A,HK2,and PKM2 proteins(all P<0.01),as well as glucose uptake and lactate production(both P<0.01)in A549 cells.miR-218-5p in A549 cells could directly bind to the 3′-UTR of PDE7A mRNA.Database data analysis showed that PDE7A mRNA was highly expressed in lung squamous cell carcinoma tissues(P<0.01).Conclusion:miR-218-5p targets PDE7A to regulate the expression levels of HK2 and PKM2 in A549 cells,which in turn inhibits the glycolytic process.miR-218-5p/PDE7A may be a potential target for clinical diagnosis and treatment of NSCLC.

OBJECTIVE To evaluate the comprehensive value of four first-line combination immunotherapy for unresectable hepatocellular carcinoma， and provide a reference for determining the optimal clinical treatment decision for unresectable hepatocellular carcinoma. METHODS R4.2 software was used for network meta-analysis to obtain the effect values of the efficacy and safety indicators of four combination therapies [atezolizumab combined with bevacizumab （AB）， sintilimab combined with bevacizumab biosimilars （SB）， camrelizumab combined with apatinib （CA）， durvalumab combined with tremelimumab （DT）]. Combined with the efficacy， safety and economic indicators， the categorical based evaluation technique （M-MACBETH） was used to establish the value tree. At the same time， the comprehensive value scores of four therapies were calculated， and sensitivity analysis was performed to evaluate the robustness. RESULTS In terms of prolonging median overall survival， the advantage order of the four therapies was ranked as SB， CA， AB and DT. In terms of extending median progression-free survival， the advantage order of the four therapies was CA， SB， AB and DT. In terms of safety， the order of advantages was DT， AB， SB and CA. In terms of economy， the order of advantages was CA， SB， AB and DT. The comprehensive scores of SB， CA， AB and DT were 67.11， 57.77， 52.53 and 42.59 points， respectively. The results of the sensitivity analysis showed that the ranking results of comprehensive value for four regimens were robust. CONCLUSIONS Among the four first-line immune combination therapies for unresectable hepatocellular carcinoma， SB is the optimal treatment regimen， followed by CA， AB and DT.

Lead is one of the most important occupational hazards in China, and occupational exposure is the leading cause of lead poisoning. Lead can be absorbed by the body through air, food, drinking water and skin, and accumulate in multiple organs in the body, posing health risks to humans, especially to lead workers. Many previous studies have shown that lead can affect the function of glial cells such as microglia, astrocytes and oligodendrocytes, resulting in irreversible neurological damage. This article provides an overview of the neurotoxic mechanism induced by lead through glial cells, elucidates that lead can induce neurodegenerative diseases such as Alzheimer′s disease, Parkinson′s disease, and amyotrophic lateral sclerosis, and reviews the relationship between lead and glial cells, in order to provide reference for further research on the neurotoxic mechanism of lead on glial cells.

Objective To investigate the effect of interaction between serum neutrophil gelatinase-associat-ed lipid carrier protein(NGAL)and complications after percutaneous coronary intervention(PCI)on poor prognosis in patients with ST-segment elevation myocardial infarction(STEMI),and to provide reference for improving prognosis.Methods From January 2017 to January 2020,a total of 400 STEMI patients admitted to this hospital were selected and divided into good prognosis group(n=378)and poor prognosis group(n=22)according to their 2-year prognosis.Logistic regression equations were used to analyze the prognostic fac-tors of STEMI patients,and multiplicative and additive effects were established to analyze the effect of the in-teraction between serum NGAL and post-PCI complications on poor prognosis.Results Gender,age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were associated with poor prognosis in STEMI patients(P＜0.05).Gender(female),age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were all inde-pendent influencing factors of poor prognosis in STEMI patients(P＜0.05).There was interaction between serum NGAL after PCI and complications after PCI,both of which had an adverse effect on the prognosis of STEMI patients(P＜0.05).There was no multiplicative interaction between serum NGAL and complications after PCI(P＞0.05).When serum NGAL and complications after PCI were exposed at the same time,the risk of poor prognosis in STEMI patients was higher than the sum of the two exposures alone,and the interaction was 2.611 times the sum of the effects of the two exposures alone.Conclusion Serum NGAL and postopera-tive complications after PCI are independent factors influencing poor prognosis in STEMI patients.There is a additive interaction between the two factors,and exposure can increase the risk of poor prognosis.

Objective:To preliminarily investigate the applicability of a poliovirus pseudovirus-based neutralization assay in evaluating the immunogenicity of recombinant poliovirus vaccines and their in vivo potency in rats. Methods:Serum samples from rats immunized with recombinant poliovirus vaccines were tested using both the pseudovirus neutralization assay and the live-virus neutralization assay with Sabin strain. The consistency and correlation of the two methods were analyzed using the Kappa test and Spearman′s rank correlation.Results:For the neutralizing antibodies against typeⅠ, Ⅱ, and Ⅲ polioviruses, the Kappa values for consistency analysis of the two methods were 0.914, 1.000, and 0.751, respectively ( P<0.001), and the correlation coefficients ( R values) were 0.833, 0.927, and 0.859, respectively ( P<0.001). Conclusions:The test results of the two methods are consistent and show a good correlation, indicating that the pseudovirus neutralization assay can be applied to evaluating the immunogenicity of poliovirus vaccines and also can be used in rat potency tests.

Follicular lymphoma (FL) is highly heterogeneous with different histopathologic grades. Its biological characteristics and clinical management are different. This study retrospectively analyzed 18F-FDG PET-CT metabolic parameters, clinical features, and their relationship with prognosis in 161 FL patients with different histopathological grades (grade 1-2, grade 3A, grade 3B) at the Shanxi Cancer Hospital. There were 93 cases in the grade 1-2 group, 40 cases in the grade 3A group, and 28 cases in the grade 3B group. The expression of LDH, CD10, EZH2, c-Myc, and CD37 proteins was correlated with histological grade (grade 1-2, grade 3A, and grade 3B) (all P values<0.05) . The SUVmax, TLG, TBR, and TLR for the three groups were different (all P values<0.05) . The optimal thresholds of SUVmax, MTV, TLG, TBR, and TLR for predicting FL disease progression were 8.32, 201.31, 2 342.55, 6.56, and 3.52, respectively, and the rate of disease progression increased in patients with higher thresholds (all P value<0.05) . β 2-MG (>2.3 μg/L) , Follicular lymphoma international prognostic index-1 (FLIPI-1) score (3-5 points) , negative CD37 expression, positive c-Myc expression, and TLG (>2 342.55 g) were all independent risk factors for PFS in the FL patients ( HR=3.609, 2.509, 0.255, 3.506, 13.531, all P value<0.05) . 18F-FDG PET-CT is a powerful complement to FL histopathological grading and the combination of the two may better predict the prognosis of FL patients.
