OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

Angiogenesis within atherosclerotic plaques is a critical determinant of plaque stability.The biome-chanical microenvironment,consisting of fluid shear force,plaque structural stress,and matrix stiffness,serves as signifi-cant factors in mediating plaque angiogenesis.Endothelial cells respond to mechanical signals and participate in plaques neovascularization through force chemical signal transduction mechanisms.This review provides an overview of the mecha-nisms by which mechanical factors regulate angiogenesis within plaques and offers a novel therapeutic approach for the pre-vention and treatment of atherosclerosis.

OBJECTIVE To explore the distribution of airborne pollen in Cangzhou,to analyze the correlation between pollen characteristics,meteorological factors and the rate of allergic rhinitis visits,and to provide a reference basis for the precise prevention and treatment of allergic rhinitis in Cangzhou.METHODS The gravity deposition method was applied to collect daily airborne pollen from the monitoring sites in Cangzhou from March to October 2022 and record the pollen species and quantities.We also collected information on allergic rhinitis patients who visited the ENT Department of Cangzhou Central Hospital during the same period and meteorological data(daily maximum temperature,minimum temperature,maximum relative humidity,maximum precipitation,and maximum wind speed at ground level)during the same period,and analyzed the relationship between the number of AR patients'visits,the amount of pollen,and the meteorological factors.RESULTS 1.A total of 229 pollen exposures were collected from March to October 2022,totaling 19 368 pollen grains,of which 18 750 grains of pollen could be identified in 19 families and 618 grains were difficult to identify the families.2.There were two peaks of pollen during the period,in April and September respectively.Spring pollen to tree-based category,to the pine family,willow willow family,Xylariaceae(ash)most often;summer pollen volume has declined,but still tree-based category;fall pollen to herbaceous category,to the Asteraceae Artemisia,mulberry,Gramineae most often.3.The pollen concentration in Cangzhou City was negatively correlated with maximum humidity,maximum precipitation,maximum temperature,and minimum temperature.Maximum wind speed at ground level was positively correlated with pollen concentration.4.Pollen concentration was positively correlated with the number of visits.The correlation analysis between daily medical visits from June to October and air pollen concentration showed a significant positive correlation,while the results from March to May showed no significant correlation.CONCLUSION The peak of airborne pollen dispersal in April and September in Cangzhou.Spring and summer pollen is dominated by tree species,and the dominant pollen is Pinaceae,Willow genus of Populus,and Xylariaceae(ash genus);fall pollen is dominated by herbaceous species,and the dominant pollen is Artemisia,Asteraceae,Mulberry,and Gramineae.Meteorological factors are important factors affecting pollen concentration.Within a certain range,the lower the maximum humidity,the lowest maximum precipitation,the lower the highest or the lowest temperature,the higher the pollen concentration,and the pollen concentration is more affected by the lowest temperature.There is a correlation between pollen concentration and the number of AR patients'visits from June to October,which can be used as an environmental early warning indicator of the prevalence of AR.

Objective:To construct a risk assessment model based on hesitant probabilistic fuzzy set(HPFS)and to explore its application value in the risk control and management of safe operation of anesthesia equipment.Methods:Taking the whole life cycle safety and management safety as the important risk assessment dimensions,the risk index system of safe operation of anesthesia equipment was constructed,HPFS and hierarchical-superior-inferior solution distance method were used to realize the quantitative analysis of risks,and the safety self-inspection and risk control treatment strategies were formulated.A total of 150 surgical patients and 16 anesthesia equipment used in surgery used in the operation were selected from July 2020 to June 2023 in Tongzhou District Maternal and Child Health Hospital,and into control group and observation group according to different management modes of anesthetic equipment,with 75 cases in each group.The 10 anesthesia machines used during the surgical treatment of the control group adopted the conventional risk control mode,and the 12 anesthesia machines used in the observation group(including 6 in the control group and the 6 newly added ones)adopted the risk assessment control mode.The incidence of perioperative anesthesia equipment-related risk events,the awareness rate of anesthesia medical staff about potential safety risks,and the failure rate of anesthesia equipment were compared between the two groups.Results:The number of perioperative risk events of improper operation of anesthesia equipment,unreasonable dosage of anesthesia,associated infection and missing records in the observation group were 4 cases(5.3%),0 cases(0%),1 case(1.3%)and 1 case(1.3%),respectively,which was lower than that in the control group,the difference was statistically significant(x2=4.478,4.110,6.857,4.754;P<0.05).The average scores of theoretical knowledge of safety management,safe use,management awareness and fault judgment ability of medical staff operating anesthesia equipment in the observation group were(96.27±3.93)points,(94.31±2.69)points,(91.82±1.94)points and(84.97±4.36)points,respectively,which were higher than those in the control group,the difference was statistically significant(t=5.176,5.322,5.541,5.942;P<0.05).The total number of equipment operation setting,anesthetic gas path,anesthesia depth monitoring,threshold alarm and other faults in the two groups were 90,37,25,316 and 125,respectively,and the failure incidence rates in the observation group were 30%(27/90),35%(13/37),28%(7/25),22%(69/316)and 39%(49/125),respectively,which were lower than those in the control group,the difference was statistically significant(x2=28.800,6.541,9.680,200.532,11.664;P<0.05). Conclusion:The risk assessment model based on HPFS can reduce the incidence of risk events related to anesthesia equipment,enhance the awareness of safety risk control of anesthesia medical staff,and improve the quality of clinical operation of anesthesia equipment.

Objective To elucidate the regulatory effects of Glycerol Kinase(GLPK)on the inflammatory response induced by lipopolysaccharide(LPS)in mouse Raw264.7 macrophages.Methods Raw264.7 macrophages were cultured in vitro,and an inflammatory model was established through LPS induction.The transcriptional levels of inflammatory cytokines NF-κB,TNF-α,IL-6,and IL-1β were quantified using RT-qPCR.The expression and localization of GLPK were examined via Western blot and immunofluorescence.Additionally,Western blot analysis was employed to detect the levels of cellular pan-succinylation and H3K23su expression.ChIP-qPCR was utilized to assess the enrichment of H3K23su modification at the IL-10 promoter.The total reactive oxygen species production was measured using DCFH-DA probes,while mitochondrial ROS levels were determined with Mito-SOX probes.Mitochondrial membrane potential changes,indicative of mitochondrial dysfunction,were evaluated using JC-1 fluorescent probes.Furthermore,GLPK overexpression plasmids were transfected into cells to investigate the effects of GLPK on inflammatory responses,mitochondrial function,and epigenetic modifications.Results LPS treatment led to mitochondrial dysfunction,inflammatory responses exacerbation,succinylation modifications reduction,and GLPK protein expression decrease in Raw264.7 cells.Overexpression of GLPK in LPS-treated cells improved mitochondrial function and reduced the transcription of pro-inflammatory cytokines.ChIP-qPCR analysis revealed that GLPK overexpression could reverse the LPS-induced suppression of H3K23su modification at the IL-10 promoter,thereby attenuating the inflammatory response.Conclusion LPS mediates inflammatory responses in Raw264.7 macrophages through a GLPK-dependent H3K23 succinylation modification mechanism.

Auscultation of heart sounds is an important method for the diagnosis of heart conditions. For most people, the audible component of heart sound are the first heart sound (S1) and the second heart sound (S2). Different diseases usually generate murmurs at different stages in a cardiac cycle. Segmenting the heart sounds precisely is the prerequisite for diagnosis. S1 and S2 emerges at the beginning of systole and diastole, respectively. Locating S1 and S2 accurately is beneficial for the segmentation of heart sounds. This paper proposed a method to classify the S1 and S2 based on their properties, and did not take use of the duration of systole and diastole. S1 and S2 in the training dataset were transformed to spectra by short-time Fourier transform and be feed to the two-stream convolutional neural network. The classification accuracy of the test dataset was as high as 91.135%. The highest sensitivity and specificity were 91.156% and 92.074%, respectively. Extracting the features of the input signals artificially can be avoid with the method proposed in this article. The calculation is not complicated, which makes this method effective for distinguishing S1 and S2 in real time.
