Objective To explore the prevalence of Helicobacter pylori (Hp) infection and its association with dietary and lifestyle habits among the adult physical examination population in Xuzhou area. Methods Retrospectively selected the physical examination population who underwent HP testing at our hospital's physical examination center from May 2021 to December 2023 as the research object. The prevalence of Hp infection in the population was analyzed based on the physical examination results. A questionnaire survey was used to collect information on the eating and living habits of all study subjects. Logistic regression was used to analyze the relationship between eating and living habits and Hp infection. Results A total of 1 354 physical examination people were included in the study, and the Hp infection rate was 37.30% (505/1354). The difference in Hp infection rates among people of different age groups is statistically significant (P<0.05), with the middle-aged population (41-59 years old) having the highest Hp positive infection rate (45.38%).High salt (41.11%), hot diet (40.56%), history of smoking (45.23%) and drinking (43.80%), less consumption of fruits and vegetables (43.73%), irregular exercise (41.29%), irregular diet People who frequently eat out (43.56%) and eat out frequently (42.57%) have a higher Hp infection rate (P<0.05).After adjusting for demographic factors such as gender, age, place of residence and education level, multivariate Logistic regression results showed that high-salt diet (OR=3.975, 95%CI: 2.670-5.917) and hot diet (OR=3.357, 95%CI: 2.291-4.919), smoking (OR=1.458, 95%CI: 1.082-1.964), drinking alcohol (OR=1.654, 95%CI: 1.279-2.138), eating fruits and vegetables (OR=1.759, 95%CI: 1.345-2.301), regular exercise (OR=1.822, 95%CI: 1.371-2.421), regular diet (OR=1.893, 95%CI: 1.391-2.575), eating out (OR=1.690, 95%CI: 1.277-2.237) were associated with the risk of Hp infection (P<0.05). Conclusion The positive infection rate of Hp among the physical examination population in Xuzhou is slightly lower than the average epidemic level in China. Cultivating healthy eating and living habits can effectively reduce the risk of Hp infection.

Functional cure of chronic hepatitis B （CHB） is defined as HBsAg<0.05 IU/mL and serum HBV DNA<10 IU/mL for at least 24 weeks after discontinuation of antiviral therapy. This requires suppression of HBV replication and reduction of viral antigen production， as well as restoration of immune response to HBV infection. About 30% — 50% of highly selected CHB patients treated with nucleos（t）ide analogues can achieve functional cure after add-on therapy or monotherapy with pegylated interferon-α or a finite course of treatment with nucleos（t）ide analogues among patients with HBsAg<100 IU/mL. At present， clinical trials are being conducted for more than 40 types of novel anti-HBV drugs and immunomodulators. The combination of drugs that inhibit viral replication， reduce antigen burden， and restore immune response to HBV infection may be an ideal strategy to achieve the functional cure of CHB. However， further studies are needed to determine the optimal drug combination， the timing and sequence of medication， and the duration of treatment.

AIM: To explore the efficacy of 0.05% cyclosporine A combined with olopatadine eye drops in treating allergic conjunctivitis-related dry eye disease.METHODS: A total of 63 patients(63 eyes)with allergic conjunctivitis-related dry eye disease in the People's Hospital of Guangxi Zhuang Autonomous Region from August 2022 to April 2023 were enrolled and randomly divided into control group(n=33)and observation group(n=30). The patients of the control group were administrated with 0.1% olopatadine eye drops and 0.3% sodium hyaluronate eye drops, while the observation group was administrated with 0.1% olopatadine eye drops and 0.05% cyclosporine A eye drops. The ocular surface disease index(OSDI), total ocular symptom score(TOSS), conjunctival congestion score, conjunctival papillae and follicle score, Schirmer I test(SⅠt), tear meniscus height(TMH), meibomian gland secretion ability and property score, meibomian gland loss area score, corneal fluorescein staining(CFS), tear film break-up time(BUT), noninvasive first tear film break-up time(NIBUTf), noninvasive average tear film break-up time(NIBUTav)before and after treatment and the drug safety during the treatment period of both groups of patients were evaluated.RESULTS: After treatment, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, SⅠt, TMH, meibomian gland secretion ability score and property score, CFS, BUT, NIBUTf, and NIBUTav of the observation group showed improvements compared with those before treatment(all P<0.017). Among these, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, BUT, NIBUTf, and NIBUTav demonstrated significant improvement compared with the control group(all P<0.05). There was no statistically significant difference in meibomian gland loss area score between the two groups before and after treatment(P>0.05). During the treatment period, there were no local or systemic adverse reactions.CONCLUSION: The combined use of 0.05% cyclosporine A and olopatadine eye drops can significantly improve ocular discomfort symptoms of patients with dry eye disease associated with allergic conjunctivitis, such as red eyes, itchy eyes and foreign body sensation, promote tear film stability and have high safety.

Objective To analyze the risk factors and effective predictive indicators for postpartum hemor-rhage(PPH)in pregnant women with severe pre-eclampsia(sPE)in singleton pregnancies.The findings will serve as a valuable reference for the clinical prevention and management of PPH in these patients.Methods A retrospective analysis was conducted on 932 pregnant women with sPE at two tertiary hospitals in Guangzhou from January 1,2016,to December 31,2022.Among these,95 cases were complicated by PPH.A comparative analysis was performed between the sPE group and the sPE with PPH group.Results(1)The incidence of assisted reproductive technology,intrapartum blood loss,placental abruption,elevated D-dimer levels,increased monocyte counts,and higher SIRI levels were significantly higher in the PPH group,whereas platelet counts were significantly lower(P<0.05).(2)The results indicated that intrapartum blood loss,D-dimer levels,and platelet counts were inde-pendently associated with PPH in pregnant women with sPE.(3)The area under the curve(AUC)for intrapartum blood loss,D-dimer,and platelet counts were 0.805,0.717,and 0.571,respectively.The optimal cutoff value for D-dimer was determined to be 2.295 μg/mL.The combined AUC for intrapartum blood loss and D-dimer was 0.859.(4)Intrapartum blood loss values were significantly higher in the PPH group for both vaginal delivery and cesarean section(P<0.001).The corresponding optimal cutoff values were 285 mL and 375 mL,respectively.Conclusions Intrapartum haemorrhage,D-dimer levels,and platelet count were identified as independent risk factors for PPH in pregnant women with sPE.Specifically,pregnant women with sPE who experienced blood loss exceeding 285 mL during vaginal delivery or 375 mL during caesarean section,along with a D-dimer level greater than 2.295 μg/mL,demonstrated an increased likelihood of developing PPH.Therefore,it is crucial to enhance clinical monitoring of these relevant indicators in high-risk populations.

Objective To observe the value of contrast-enhanced ultrasound(CEUS)for evaluating DeBakey Ⅰ aortic dissection involved renal artery.Methods Totally 137 patients with DeBakey Ⅰ aortic dissection involved renal artery were retrospectively enrolled,including 132 cases involved unilateral and 5 cases involved bilateral renal arteries.The opening of totally 274 renal arteries in bilateral kidneys were observed.Taken CT angiography(CTA)as reference standard,the renal artery opened in true lumen was considered as unaffected,while opened in false lumen or true-false lumen were both considered as affected.Relative CEUS manifestations were observed,and their value for evaluating involved renal artery or not were analyzed.Results CTA showed that 132 renal arteries opened in true lumens,90 opened in false lumens and 52 opened in true-false lumens.CEUS diagnosed 131 renal arteries opened in true lumens,111 opened in false lumens and 32 opened in true-false lumens,and the sensitivity for diagnosing DeBakey Ⅰ aortic dissection involved renal artery was 90.84％,81.08％and 90.63％,respectively.The consistency between CEUS and CTA for evaluating renal artery opened in true lumen or false lumen was good(Kappa=0.786).Logistic regression analysis showed that the time to peak(TTP)and peak intensity(PI)of time intensity curve(TIC)were both impact factors for differentiating renal artery opened in true lumen or false lumen,as well as true lumen or true-false lumen(both P＜0.05),while the area under the curve(AUC)of TIC was impact factor for differentiating renal artery opened in true lumen or false lumen(P＜0.05).The AUC of receiver operating characteristic curve of the combination of TTP,PI and AUC of TIC for differentiating renal artery opened in true lumen or false lumen,true lumen or true-false lumen and false lumen or true-false lumen was 0.703,0.686 and 0.493,respectively.Conclusion CEUS was helpful for evaluating DeBakey Ⅰ aortic dissection involved renal artery.

Objective To assess the dietary quality of preschool children and explore the relationship between feeding practices and dietary quality.Methods Relying on the Shanghai Maternal-Child Pairs Cohort,3 177 preschool children were selected as the subjects for this study,and questionnaire were surveyed on their dietary intake and feeding practice.The diet balance index was used to evaluate dietary quality among preschool children.High bound score(HBS),the low bound score(LBS),and the dietary quality distance(DQD)were calculated to respectively reflect overall dietary overconsumption,insufficiency,and imbalance.Logistic regression was utilized to analyze the association between feeding practice and dietary quality in preschool children.Results The HBS,LBS,and DQD of the subjects were 2(0,8),22.19±10.80,and 26.78±9.57,respectively.Only 7.68%of the children had a balanced dietary intake,with 74.73%and 33.99%of overall dietary intake being inadequate and excessive,respectively.Parental perceived weight were negatively associated with the risk of moderate to high over intake among children(aOR=0.79,95%CI:0.63-0.98).The higher the perceived responsibility(aOR=1.19,95%CI:1.03-1.37)score,the lower the monitoring score(aOR=0.83,95%CI:0.74-0.93),and the higher the likelihood that the child had a moderate to high under intake.The scores of pressure to eat were also positively correlated with the risks of under intake and moderate to high overall unbalance in preschool children(aOR=1.15-1.39,95%CI:1.02-1.63).Conclusion Preschool children commonly experience dietary imbalance,with inadequate and excessive intake coexisting.Parental perceived weight and monitoring were positively associated with preschoolers'dietary quality,whereas perceived responsibility and pressure to eat were negatively associated with it.

A subset of patients with multiple myeloma(MM)present with reduced serum vitamin B12 levels at initial diagnosis;however,its clinical significance and underlying mechanisms remain unclear.Vitamin B12 plays a crucial role in hematopoiesis and immune regulation.This study aims to elucidate its association with extramedullary diseases,immune function,and prognosis in MM patients.A retrospec-tive analysis was conducted of 92 newly diagnosed MM patients,who received treatment at the Second Af-filiated Hospital of Soochow University between January 2020 and December 2023.Patients were classi-fied into a low vitamin B12 group(n=37)and a normal vitamin B12 group(n=55)based on their ser-um vitamin B12 levels.The findings revealed that the incidence of extramedullary infiltration was signifi-cantly higher in the low vitamin B12 group than in the normal group(26.5％vs.17.0％,P=0.031).Survival analysis demonstrated that patients with low vitamin B12 levels had significantly shorter overall survival(OS)and progression-free survival(PFS)(OS:P=0.0123;PFS:P=0.0136).Additionally,these patients showed a decreasing trend in peripheral blood total T cell,CD4+T cell,and CD8+T cell counts,with serum vitamin B12 levels showing a significant positive correlation with the total T cell count(R=0.2717,P=0.0135)and CD4+T cell count(R=0.2175,P=0.0497).In conclusion,reduced serum vitamin B12 levels at initial diagnosis are significantly associated with poor prognosis in MM pa-tients and may serve as a potential prognostic biomarker.Furthermore,vitamin B12 deficiency may con-tribute to immune dysfunction,particularly impaired T cell immunity,and a higher incidence of extr-amedullary diseases.

Objective To analyze the multi-target mechanism of Paeoniflorin in the intervention of oral submucosal fibrosis(OSF)systematically,based on molecular dynamics simulation and network pharmacology.Methods Identify potential targets of Paeoniflorin were predicted by using database.OSF-related disease targets and identified drug-disease intersecting targets were screened.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis were conducted to validate the molecular binding capabilities between Paeoniflorin and core targets.Finally,molecular dynamics simulations were performed to verify binding stability.Results A total of 20 overlapping targets were identified,including key genes such as transforming growth factor(TGF)-β1,interleukin(IL)-6,and tumor necrosis factor(TNF)-α.TGF-β1,IL-6,and TNF formed the core hub.The enrichment analysis revealed that the target molecules were significantly enriched in the TGF-β1,phosphatidylinositol 3-kinease-actin(PI3K-Akt),and nuclear factor κB(NF-κB)signaling pathways.Molecular docking confirmed high affinity binding of Paeoniflorin to targets including TGF-β1,while molecular dynamics simulations verified stable interactions between Paeoniflorin and both TGF-β1 and B-cell lymphoma-2 targets.Conclusion This study revealed that Paeoniflorin inhibits the inflammatory-fibrotic cascade of OSF through synergistic regulation of TGF-β1/Smad,PI3K-Akt and NF-κB pathways.

Objective:To explore the expression level of m6A methyltransferase ZC3H13 gene in primary acute myeloid leukemia(AML)and its relationship with clinical features and prognosis.Methods:A total of 131 newly diagnosed AML patients and 12 controls were enrolled from July 1,2018 to December 1,2021 in the Hematology Department of the Second Hospital of Shanxi Medical University.RT-qPCR technology was used to detect the expression level of ZC3H13 mRNA in bone marrow(BM)samples.A retrospective analysis was conducted to examine the correlation between ZC3H13 expression level and clinical indicators,gene mutations,and prognosis.Results:The expression level of ZC3H13 mRNA in primary AML patients was significantly higher than that in the control group(P＜0.001).The white blood cell count,proportion of BM blast cells,and relapse rate in the high ZC3H13 expression group were higher than those in the the low ZC3H13 expression group(all P＜0.05),while the Th/Ts ratio was lower(P＜0.01).Univariate survival analysis showed that patients with high expression of ZC3H13 had shorter median overall survival(OS)and disease-free survival(DFS)than those with low expression of ZC3H13(both P＜0.05).The results of multivariate Cox regression analysis showed that high-risk stratification(OS:HR=1.612,95％CI:1.151-2.257,P=0.005;DFS:HR=1.551,95％CI:1.031-2.335,P=0.035)and high ZC3H13 expression(OS:HR=1.756,95％CI:1.028-2.999,P=0.039;DFS:HR=1.935,95％CI:1.018-3.678,P=0.044)were both independent risk factors for OS and DFS in AML patients.Conclusion:The expression of ZC3H13 in AML patients may be related to tumor burden and immune function.Patients with high expression of ZC3H13 have poor prognosis,and high expression of ZC3H13 is an independent risk factor for the prognosis of AML patients.
