Objective To investigate the relationships of serum procalcitonin(PCT),α1-acid glycoprotein(α1-AGP)and cluster of differentiation 64(CD64)index with the severity of illness and prognosis in patients with pulmonary Candida infection after lung cancer surgery.Methods A pro-spective study was conducted in 120 patients with pulmonary Candida infection after lung cancer sur-gery as infection group,and 60 patients without infection after lung cancer surgery in the same period were selected as control group.Baseline characteristics and laboratory indicators were compared be-tween the two groups.Differences in serum PCT,α1-AGP,CD64 index in peripheral blood,and plasma 1,3-β-D glucan test(BG)were compared among patients with different severities of illness and prognoses in the infection group.The relationship between serum indicators and prognosis as well as their predictive efficiencies were analyzed,and external validation was performed.Results The levels of serum PCT,α1-AGP,CD64 index in peripheral blood,and plasma BG in the infection group were significantly higher than those in the control group(P＜0.05).In the infection group,the levels of serum PCT,α1-AGP,and CD64 gradually decreased significantly in patients with severe,moderate,and mild illness,and the levels of these indicators in dead patients were significantly higher than those in surviving patients(P＜0.05).Survival curve analysis showed that patients with low levels of serum PCT,α1-AGP,and CD64 index before treatment had higher survival rates than those with high levels of these indicators.Receiver operating characteristic(ROC)curve analysis revealed that the combined prediction of PCT,α1-AGP,and CD64 index for mortality was superior to individual indicators or their pairwise combinations,and external validation confirmed the good predictive efficacy of the combined prediction.Conclusion PCT,α1-AGP,and CD64 index are closely related to pulmonary Candida infection after lung cancer surgery,and the combined detection of these indicators has certain predictive value for 28-day prognosis.

Objective To explore the effect of saururus chinensis tannin on proliferation and mi-gration of non-small cell lung cancer(NSCLC)cells by regulating Hippo/YAP signaling pathway.Methods Human NSCLC cell line A549 was treated with different concentrations of saururus chinen-sis tannin.Cell viability was detected by CCK-8 assay to screen appropriate drug concentrations.NSCLC cells were randomly divided into control group,low-concentration saururus chinensis tannin group,medium-concentration saururus chinensis tannin group,high-concentration saururus chinensis tannin group and high-concentration saururus chinensis tannin+YAP activator(XMU-MP-1)group.Cell viability,colony formation capacity,migration ability and invasion ability were evaluated using the CCK-8 assay,plate colony formation assay,wound healing assay and transwell assay,respective-ly.Expression levels of proteins associated with migration and invasion[E-cadherin,N-cadherin and snail]and proteins related to the Hippo/YAP signaling pathway[Yes-associated protein(YAP),phosphorylated Yes-associated protein(p-YAP),connective tissue growth factor(CTGF)and cys-teine-rich angiogenic inducer 61(CYR61)]were detected by western blot analysis.Results Com-pared with the control group,the cell viability,the number of colony cells,migration and invasion abilities,as well as the expression levels of N-cadherin,snail,YAP,CTGF and CYR61 proteins in the low-concentration saururus chinensis tannin group,medium-concentration saururus chinensis tannin group and high-concentration saururus chinensis tannin group were significantly decreased or reduced,and the expression levels of E-cadherin and p-YAP proteins were significantly increased(P＜0.05),with the most pronounced effects observed in the high-concentration saururus chinensis tannin group.Compared with the high-concentration saururus chinensis tannin group,the cell viabil-ity,the number of colony cells,migration and invasion abilities,as well as the expression levels of N-cadherin,snail,YAP,CTGF and CYR61 in the high-concentration saururus chinensis tannin+YAP activator group were significantly increased or enhanced,while the expression levels of E-cad-herin and p-YAP were significantly decreased(P＜0.05).Conclusion Saururus chinensis tannin may reduce the survival rate of NSCLC cells and inhibit their proliferation,migration and invasion a-bilities by regulating the Hippo/YAP signaling pathway.

Objective To explore the relationship between haptoglobin gene polymorphism and disease se-verity and susceptibility in senile vascular dementia patients.Methods A total of 80 patients with senile vas-cular dementia admitted to the hospital from February 2018 to February 2023 were selected as the vascular de-mentia group,and 80 stroke patients with non-vascular dementia admitted to the hospital during the same pe-riod were selected as the control group.The genotype distribution and allele frequency of haptoglobin gene were measured using polymerase chain reaction with sequence-specific primers,and their relationship with the severity and susceptibility of vascular dementia patients was analyzed.Results The proportion of history of hyperlipidemia and diabetes mellitus and the levels of total cholesterol and triglyceride in vascular dementia group were higher than those in control group,the differences were statistically significant(P＜0.05).The distribution of genotypes was in Hardy-Weinberg equilibrium(P＞0.05).The frequency of haptoglobin 2-2 genotype and haptoglobin 2 allele in vascular dementia group were higher than those in control group,and the differences were statistically significant(P＜0.05).There were significant differences in the scores of mini-mental state examination and hachinski ischaemic score among patients with vascular dementia with different haptoglobin genotypes(P＜0.05).Multivariate Logistic regression analysis showed that the carrier of hapto-globin 2-2 genotype and the carrier of haptoglobin 2 allele were independent risk factors for vascular dementia(P＜0.05).Conclusion Haptoglobin 2-2 genotype and haptoglobin 2 allele distribution frequency are associ-ated with the occurrence of vascular dementia after stroke,and those with high frequency of haptoglobin 2-2 genotype and haptoglobin 2 allele distribution suffer a severe disease,which can provide reference for early i-dentification and assessment of vascular dementia.

Gastric ulcer is a common digestive system disease,and the long-term use of non-steroidal anti-inflammatory drugs(NSAIDs)is the second most important cause.NSAID-induced gastric ulcer animal models are key experimental tools for studying the pathogenesis,corresponding treatment method,and effective mechanisms of NSAID-induced gastrointestinal injury.However,there are currently a lack of reviews on NSAID-induced gastric ulcer animal models.This review summarizes and compares the relevant literature on animal research into indomethacin-and aspirin-induced gastric ulcers in the past 10 years,including the selection of experimental animals,drug solvents,and specific modeling method.The limitations of current models,such as the cumbersome modeling method,incomplete modeling details,inadequate models for clinical use,and lack of comparative drug research,are discussed.Feasible solutions are proposed with the aim of providing an effective reference for research in this field.
