Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

Background: Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomavirus (HPV). In recent years, research on anal CA has primarily focused on treatment rather than underlying mechanisms. The mechanism of HPV persistence and recurrence in CA require further exploration. It needs multiple researches in mechanisms to focalize treatment targets. Objective: To investigate the relationship between intestinal mucosal immunity and the relapse of anal CA and persistent infection. Methods: Levels of interferon gamma (IFN-γ) and secretory immunoglobulin A (sIgA) were measured using enzyme-linked immunosorbnent assay in anal mucosal cells obtained from patients treated at Tianjin Union Medical Center from September 2022 to December 2024. All the participants signed Informed Consent and the whole plan was approved by Institutional Review Board in Tianjin Union Medical Center (No. B155). Results: The levels of IFN-γ and sIgA significantly decreased after infection, and persistent infection exhibited even lower levels. These two factors increased following treatment, reaching peak concentrations at 4 weeks before decreasing again. Conclusion These findings demonstrate a significant association between persistent anal CA infection and dysregulation of intestinal mucosal immunity.

Objective To explore factors affecting blood pressure control in chronic disease patients in China's na-tional basic public health service chronic disease patient management program and to find their relationships with Bayesian network(BN)model,in order to provide a scientific basis for comprehensive hypertension management.Methods 5 577 Hypertensive patients were selected from eight provinces(including autonomous regions)covering eastern,central and western parts of China during a survey from 2021 to 2022.Researchers collected individual and community-management data to screen influencing factors by Logistic regression,and to describe factor dependencies and to identify key determinants of blood pressure control with BN in.blood pressure control.Results Logistic regression revealed that urban/rural status,education,alcohol use,exercise,overweight/obesity and com-munity-doctor advice on salt reduction,smoking cessation were significantly associated with blood pressure control(P＜0.05).The BN model identified 22 directed edges showing that urban residence and good hypertension knowl-edge were more correlated with better control,while community-doctor management and services directly affected patient lifestyle habits but not blood pressure control.Conclusions Research should focus more on urban-rural dis-parities and hypertension education.Additionally,improving patient habits and community-doctor services is essen-tial for better blood pressure control.

Objective To analyze the etiological characteristics of pediatric bacterial meningitis(BM)and change of biochemical indicators in cerebrospinal fluid,and establish a diagnostic model for pathogen differentiation based on biochemical indicators in cerebrospinal fluid.Methods Eighty children with BM in the Children's Hospital Affiliated to Zhengzhou University from May 2021 to May 2023 were selected as BM group,and their pathogen distribution as well as cytological and biochemi-cal indicators in cerebrospinal fluid were analyzed.Forty non-central nervous system infections chil-dren with cytological and biochemical testing in cerebrospinal fluid in the same period were included as control group.The relationships between indicators in cerebrospinal fluid and pathogen types in BM children were analyzed,and a diagnostic model was constructed.Results A total of 85 pathogens were detected in 80 BM children,including 48 Gram-negative bacteria(56.47％)and 37 Gram-pos-itive bacteria(43.53％).The BM group showed significantly higher white blood cell count and lym-phocyte percentages,lower neutrophil and monocyte percentages,lower glucose and chloride levels in cerebrospinal fluid,and higher protein levels in cerebrospinal fluid when compared to the control group(P＜0.05).Among BM children,those infected with Gram-negative bacteria had significantly higher white blood cell count and lymphocyte percentages,as well as lower glucose and chloride levels in cerebrospinal fluid when compared to those with Gram-positive bacterial infections(P＜0.05).Multivariate Logistic analysis revealed that white blood cell count,lymphocyte percentage,glucose,and chloride levels in cerebrospinal fluid were significantly associated with pathogen types(P＜0.05).A diagnostic model based on these factors demonstrated an area under the receiver operating characteristic(ROC)curve of 0.925 for distinguishing Gram-positive and Gram-negative infections,with a cutoff value of 0.754,asensitivity of 76.25％,and aspecificity of 98.33％.Conclusion The primary pathogens of pediatric BM include Acinetobacter baumannii,Escherichia coli,Klebsiella pneumoniae,coagulase-negative Staphylococcus,Staphylococcus aureus,and Streptococcus pneumoni-a,accompanied by elevated white blood cell count and lymphocyte percentages as well as reduced glucose and chloride levels in cerebrospinal fluid,which is helpful in differentiating Gram-positive from Gram-negative infections and guiding antibiotic therapy.

ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang （BWT） on non-alcoholic fatty liver disease （NAFLD） and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups： normal control， model， positive drug （pioglitazone hydrochloride 1.95×10^-3 g·kg^-1）， and low-， medium-， and high-dose BWT （1.3，2.5 and 5.1 g·kg^-1）. Following a 12-week high-fat diet （HFD） inducement， the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week， glucose tolerance （GTT） and insulin tolerance （ITT） tests were conducted. Subsequently， the mice were euthanized for the collection of liver tissue and serum， and the subcutaneous adipose tissue （iWAT） and epididymal adipose tissue （eWAT） were weighed. Serum levels of total triglycerides （TG） and liver function indicators，such as alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， were determined. Histological examinations， including oil red O staining， hematoxylin-eosin （HE） staining， Masson staining， and transmission electron microscopy， were performed to evaluate hepatic lipid deposition， pathological morphology， and ultrastructural changes， respectively. Meanwhile， Western blot and real-time quantitative polymerase chain reaction （Real-time PCR） were employed to analyze alterations， at both gene and protein levels， the insulin signaling pathway molecules， including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 （IRS1/2/Akt/FoxO1）， glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase （Pepck） and glucose-6-phosphatase （G6Pase）， lipid metabolism-related genes stearoyl-coA desaturase-1 （SCD-1） and carnitine palmitoyltransferase-1 （CPT-1）， fibrosis-associated molecules α-smooth muscle actin （α-SMA）， type Ⅰ collagen （CollagenⅠ）， and the fibrosis canonical signaling pathway transforming growth factor-β₁/drosophila mothers against decapentaplegic protein2/3（TGF-β₁/p-Smad/Smad2/3）， inflammatory factors such as interleukin（IL）-6， IL-8， IL-11， and IL-1β， autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1， and the expression of mammalian target of rapamycin （mTOR）. ResultCompared with the model group， BWT reduced the body weight and liver weight of NAFLD mice（P<0.05， P<0.01）， inhibited liver lipid accumulation， and reduced the weight of white fat： it reduced the weight of eWAT and iWAT（P<0.05， P<0.01） as well as the serum TG content（P<0.05， P<0.01）. BWT improved the liver function as reflected by the reduced ALT and AST content（P<0.05， P<0.01）. It improved liver insulin resistance by upregulating IRS2， p-Akt/Akt， p-FoxO1/FoxO1 expressions（P<0.05）. Besides， it improved glucose and lipid metabolism disorders： it reduced fasting blood glucose and postprandial blood glucose（P<0.05， P<0.01）， improved GTT and ITT（P<0.05， P<0.01）， reduced the expression of Pepck， G6Pase， and SCD-1（P<0.01）， and increased the expression of CPT-1（P<0.01）. The expressions of α-SMA， Collagen1， and TGF-β₁ proteins were down-regulated（P<0.05， P<0.01）， while the expression of p-Smad/Smad2/3 was downregulated（P<0.05）， suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6， IL-8， IL-11 and IL-1β（P<0.01） and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression（P<0.05）while downregulating the expression of p62/SQSTM1 and mTOR（P<0.05）. ConclusionBWT ameliorates NAFLD by multifaceted improvements， including improving IR and glucose and lipid metabolism， anti-inflammation， anti-fibrosis， and enhancing autophagy. In particular， BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

OBJECTIVE: To explore the effectiveness of the combined anteversion angle technique in total hip arthroplasty (THA) for treating ankylosing spondylitis (AS) affecting the hip joint. METHODS: A retrospective analysis was conducted on the clinical data of 73 patients with AS affecting the hip joint who underwent THA between August 2018 and August 2021. According to whether the combined anteversion angle technique was used in THA, the patients were divided into study group (37 cases, combined anteversion angle technique was used in THA) and control group (36 cases, traditional THA). There was no significant difference in baseline data such as gender, age, body mass index, disease duration, preoperative Harris score, range of motion (ROM), acetabular anteversion angle, acetabular abduction angle, femoral anteversion angle, and combined anteversion angle between the two groups ( P>0.05). The operation time, hospital stay, and complications of the two groups were recorded and compared. The Harris score and hip ROM were compared between the two groups before operation, at 1, 3, 6, 12 months after operation, and at last follow-up. The acetabular component anteversion angle, femoral component anteversion angle, acetabular component abduction angle, and component combined anteversion angle were measured postoperatively. RESULTS: The operation time in the study group was significantly shorter than that in the control group ( P<0.05), and there was no significant difference in hospital stay between the two groups ( P>0.05). There was no intraoperative complication such as acetabular and proximal femoral fractures, neurovascular injuries in both groups, and the incisions healed by first intention. All patients were followed up 2-3 years, with an average of 2.4 years; there was no significant difference in the follow-up time between the two groups ( P>0.05). During the follow-up period, there was no complication such as hip dislocation, wound infection, delayed wound healing, deep venous thrombosis, and hip dislocation in both groups. The hip Harris score and ROM of the two groups gradually increased with time after operation, and the differences were significant when compared with those before operation ( P<0.05); the above two indicators of the study group were significantly better than those of the control group at each time point after operation ( P<0.05). Extensive bone ingrowth on the surface of the components could be observed in the anteroposterior X-ray films of the hip joint of the two groups at 12 months after operation, and the acetabular components was stable without femoral stem subsidence, osteolysis around the components, and heterotopic ossification. At last follow-up, the acetabular component anteversion angle, femoral component anteversion angle, and component combined anteversion angle in the study group were significantly superior to those in the control group ( P<0.05), except that there was no significant difference in the acetabular component abduction angle between the two groups ( P>0.05). CONCLUSION For patients with AS affecting the hip joint, the use of the combined anteversion angle technique during THA effectively promotes the recovery of hip joint function and enhances the postoperative quality of life of patients when compared to traditional THA.

Objective:To explore the brain activation intensity changes of depressed patients in the phase of expected value (EV), positive prediction error (+ PE) and negative prediction error (-PE) under uncertain (risky, ambiguous) decision-making.Methods:From July 2018 to February 2021, a total of 48 depressed patients in the Affiliated Hospital of Qingdao University were collected (depression group), and 69 sex-, age-, and educational level-matched healthy people were recruited as the control group. All participants completed risky and ambiguous decision-making tasks under the E-Prime system.SA-9800 brain functional audio-visual stimulation system and GE3.0 T functional magnetic resonance imaging (fMRI) scanners were used to conduct synchronous scanning and data acquisition. Using Xjview software to analyze the activation intensity of related brain areas to compare the activity intensity of the two groups.SPSS 16.0 software was used for chi square test, independent sample t-test. Results:Under risky decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral prefrontal cortex (PFC)(MNI coordinate: left x=-45, y=21, z=-6; right x=0, y=69, z=-3), left para hippocampal gyrus(PHG)(MNI coordinate: x=-9, y=0, z=-22), bilateral occipital lobe(OL)(MNI coordinate: left x=-51, y=-81, z=-3; right x=48, y=-84, z=-9)( P<0.05). The brain areas with reduced activation during + PE phase were bilateral PFC, left hippocampus (HIP), bilateral temporal lobe (TL), left middle occipital gyrus( P<0.05). The brain areas with reduced activation were bilateral PFC, right putamen, bilateral TL( P<0.05) during -PE phase. Under ambiguous decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral PFC, right OL( P<0.05); the brain areas with reduced activation during + PE phase were bilateral PFC, right putamen and hippocampus, bilateral TL, bilateral OL( P<0.05); and the brain areas with reduced activation were bilateral PFC, bilateral TL( P<0.05) during -PE phase. Conclusion:The study shows that the activities of reward brain areas such as PFC, limbic system and OL system are reduced during EV and PE phase under uncertain decision-making in depressed patients.

Objective:We aimed to analyse the trend of incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 and predict the development trend from 2023 to 2030.Methods:Data on incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 were obtained from Shandong Cancer Registry. The incidence, age-specific incidence, mortality and age-specific mortality in different years, sexes and urban and rural areas were calculated, the rates were standardized based on the age composition of the Chinese standard population in 2000. The average annual percent change (AAPC) of incidence and mortality was calculated using Joinpoint software. The Bayesian age-period-cohort model was used to predict the trend of stomach cancer incidence and mortality from 2023 to 2030.Results:From 2012 to 2022, the stomach cancer age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) showed a decreasing trend. The ASIR decreased from 27.47/100 000 in 2012 to 16.06/100 000 in 2022 (AAPC=-5.10%, P＜0.001), and the ASMR decreased from 17.69/100 000 to 11.09/100 000 (AAPC=-5.52%, P＜0.001). The ASIR and ASMR of male, female, urban and rural population also showed downward trends. The incidence and mortality rates of men were always higher than those of women, and the difference between urban and rural areas is gradually narrowing. In 2022, the ASIR (16.09/100 000 in urban and 16.03/100 000 in rural) and the ASMR (11.10/100 000 in urban and 11.08/100 000 in rural) of stomach cancer between urban and rural areas were nearly identical. The Bayesian age-period-cohort model predicted that the ASIR of stomach cancer in Shandong would further decrease from 2023 to 2030 (AAPC=-0.51%, P=0.001), but the change tended to be smooth. The incidences in male (AAPC=-1.46%, P=0.010) and rural areas (AAPC=-1.21%, P＜0.001) were still expected to have a little room for decline. The trend of incidences in female and urban areas were not statistically significant. The trend of mortality was consistent with the incidence. Conclusions:The stomach cancer incidence and mortality in Shandong shows a decreasing trend and it is expected to decrease further by 2030. However, the trend tends to be smooth, and the disease burden should be reduced as early as possible for high-risk population and high-risk factors of stomach cancer.

Objective:To employ qualitative research methods to evaluate the sustainability of the Shandong-Ministry of Health Action on Salt and Hypertension (SMASH) interventions and their influencing factors.Method:In September 2023, interviewees meeting the inclusion criteria were recruited through purposive sampling in Jinan, Shandong Province. A semi-structured interview guide was designed based on the CFIR and RE-AIM frameworks. Personal in-depth interviews and focus group discussions were conducted to gather insights on the feasibility, effectiveness, and sustainability of the project interventions from various stakeholders, including representatives from the government, food manufacturers, restaurants, academia, and residents.Results:A total of 15 individuals participated in in-depth interviews, involving six representatives from food manufacturers, four from restaurants, three from the government, and two from academia. There were four focus group discussions with 30 residents. The study found that at the individual resident level, health awareness and the availability of sodium reduction tools in the market could affect their salt reduction practices. For food manufacturers and restaurants, consumers′ preferences, technical challenges in reformulation, and government support were key factors determining the smooth progress of their salt reduction efforts. At the governmental level, multi-sectional coordination, chronic disease management demonstration areas, and the impact of the pandemic were the main factors influencing the implementation of sodium reduction interventions.Conclusion:Future endeavours should strengthen long-term management and optimise the complex influencing factors associated with intervention measures. This will be essential in sustaining and expanding the positive health outcomes achieved through the Shandong population sodium reduction strategy.
