ObjectiveTo investigate the influenza vaccination coverage among kindergarten and primary school children in Zhejiang Province in 2023 and analyze the influencing factors, and to provide the basis for improving the effect of influenza vaccination in children. MethodsA multi-stage random cluster sampling method was used to select 3 681 parents of children from 10 primary schools and kindergartens based on economic level and geographical distribution in Zhejiang Province, who participated in an online questionnaire survey, including basic information about the children and their parents, parents’ knowledge about influenza, and their willingness to vaccination. ResultsAmong the 3 681 parents surveyed, 33.82% (1 245/3 681) reported that their children received influenza vaccination in 2023. Multivariate logistic regression analysis showed that factors contributing to children’s influenza vaccination included both parents [adjusted OR (95%CI): 1.56 (1.32‒1.84)] and children [6.04 (5.04‒7.27)] having a history of influenza vaccination, parents’ conviction the influenza vaccine could protect children from severe diseases [1.43 (1.19‒1.74)], and the willingness of most parents would let their children get vaccinated [1.40 (1.13‒1.74)]. In contrast, vaccine hesitancy among parents [0.55 (0.43‒0.69)] and the belief that influenza is just a common cold [0.80 (0.65‒1.00)] were hindering factors. ConclusionThe influenza vaccination coverage among children is insufficient. Both the vaccination history of parents and children, as well as parents’ correct understanding of influenza and the effectiveness of influenza vaccine, significantly influence the influenza vaccination status in children. Efforts to address vaccine hesitancy and misconceptions about influenza are essential to improve vaccination rates.

OBJECTIVES: To investigate the medium- and long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation for treatment of iliac vein stenosis with lower extremity deep venous thrombosis (LEDVT). METHODS: Clinical and follow-up data of 125 patients with iliac vein stenosis and LEDVT who underwent PMT and stent implantation at five hospitals in northern Zhejiang province from January 2017 to June 2021 were collected. The thrombus clearance rate, thrombus recurrence rate, patency rate of iliac vein stents and post-thrombotic syndrome (PTS) occurrence rate were documented, and safety indicators such as bleeding, death, pulmonary embolism, stent fracture and displacement were assessed. RESULTS: Among 125 patients, for clearance of limb thrombosis, there were 8 cases of grade I (6.4%), 10 cases of grade II (8.0%), and 107 cases of grade III (85.6%). Patients were followed up for a median period of 74 months. According to the Villalta score, the recurrence rates of limb thrombosis at 12, 24 and 36 months were 8.48%, 8.93% and 10.91%; the iliac vein patency rates were 91.52%, 91.07%, and 89.09%; and the incidences of PTS were 5.08%, 5.36% and 6.36%, respectively. There were no major adverse events such as death, massive pulmonary embolism or severe hepatic and renal insufficiency, and no readmission intervention events due to stent fracture or other incidence were found. CONCLUSIONS PMT combined with iliac vein stent implantation is effective for patients with iliac vein stenosis complicated by LEDVT with good medium- and long-term efficacy and safety, which is worthy of clinical application.

【Objective】 To explore the correlation between different feeding styles of caregivers and diet quality of children with nutritional problems, in order to provide reference for making effective feeding guidance and intervention strategy. 【Methods】 From January 2022 to August 2023, 2- to 6-year-old children who had been enrolled in kindergartens or nurseries and their caregivers from the combined outpatient department of Child Healthcare and Nutrition in Shanghai Children′s Hospital were selected into this study.The amount of dinner served and consumed was obtained through the three-day dinner intake survey, and the Chinese Healthy Eating Index (CHEI) was calculated.Feeding styles were divided into four groups through the Caregiver Feeding Style Questionnaire.Pearson correlation analysis was used to determine the correlation between served and consumed CHEI score.Chi-square test, t-test and ANOVA were used to compare the differences in CHEI score for dinner consumed in children with different feeding styles. 【Results】 1) Totally 133 parent-child pairs were included in this study.There were 68 boys (51.1%) and 65 girls (48.9%), with an average age of (4.6±0.6) years.2) CHEI scores for dinner served was highly correlated with that for dinner consumed (r=0.90, P<0.05).There was statistically significant difference between the CHEI score for dinner served and consumed by authoritative and authoritarian feeding styles (t=2.538, 1.732, P<0.05).3) After adjusting body shape, children in the authoritative feeding style actually completed a significantly higher diet quality CHEI score than those in the authoritarian feeding style (P<0.05).4)Authoritative and indulgent feeding styles had statistical differences in the distribution of children′s body size (χ²=13.587, P=0.035). 【Conclusions】 Parents with authoritarian feeding style and indulgent feeding style have worse control over their children′s dietary completion.Children with authoritative feeding style have higher dietary quality than those with authoritarian feeding style.Children with indulgent feeding style may have a higher proportion of non-low weight than those with authoritative feeding style.Although feeding style could not reverse the outcome of body shape deviation in children with disease, it may have some positive effects.

Objective:To explore the effect of paeoniflorin on LPS-induced bronchial epithelial cell inflammatory response by regulating NF-κB pathway.Methods:BEAS-2B cells were cultured in vitro for paeoniflorin toxicity assay and concentration screening.BEAS-2B cells were divided into control group,LPS group,LPS+CAPE group,LPS+PF group and LPS+CAPE+PF group.Inflammatory responses were induced in BEAS-2B cells using LPS(1 μg/ml),and cell viability was detected by CCK-8 assay after administration of paeoniflorin or CAPE interventions.Apoptosis and cell cycle were detected by flow cytometry.The levels of IFN-γ,IL-4,IL-17C and IL-10 were detected by ELISA.The protein expression levels of p53,Bcl-2,Bax,Cyclin1,NF-κB and p-p65 were detected by Western blot.Results:Paeoniflorin increased cell viability,inhibited apoptosis,increased IFN-γ and IL-10 levels(P<0.01),de-creased IL-4 and IL-17C levels(P<0.01),down-regulated the protein expression levels of p53,Bax,NF-κB and p-p65(P<0.01),and up-regulated the protein expression levels of Bcl-2 and Cyclin1(P<0.01).The effect of paeoniflorin was more significant after the intervention of NF-κB inhibitor CAPE.Conclusion:Paeoniflorin reduces LPS-induced inflammatory factor levels in bronchial epithelial cells by regulating the NF-κB pathway,thereby suppressing the asthmatic inflammatory response.

Objective To investigate the changes of cortical thickness in patients with insomnia disorder(ID).Methods High-resolution MRI data were collected from 32 ID patients(ID group)and 30 healthy controls(HC)(HC group).The cortical thickness of both groups were analyzed using statistical parametric mapping 12(SPM12)software,while considering age,gender,and educational level as covariates.The cortical thickness in brain regions showed statistically significant differences was extracted for Pearson's correla-tion analyses with sleep and mood-related scales.Results Compared with the HC group,the ID group exhibited significantly decreased cortical thickness in brain regions such as the left insula,fusiform gyrus,orbitofrontal lobe,superior temporal gyrus,middle temporal gyrus,lateral occipital lobe and right caudal anterior cingulate gyrus[P＜0.05,family-wise error(FWE)correction].Furthermore,reduced cortical thickness of the cingulate gyrus was negatively correlated with the Pittsburgh sleep quality index(PSQI)score(r=-0.437,P=0.012).Conclusion The cortical thickness of several brain regions associated with sleep and mood are significantly reduced in patients with ID,providing potential neuroimaging evidence for understanding the pathophysiological mechanism of ID.

Objective To explore the risk factors and prognosis of cardiogenic shock in elderly pa-tients with acute myocardial infarction(AMI).Methods A retrospective trial was conducted on 398 AMI patients admitted to our hospital from January 2020 to December 2023.Based on occur-rence of cardiogenic shock during hospitalization or not,they were divided into a cardiogenic shock group(n=99)and a control group(n=299).Clinical characteristics were compared between the two groups to analyze the risk factors of cardiogenic shock,and the impact of cardiogenic shock on the prognosis was investigated.Results The cardiogenic shock group had significantly larger pro-portions of aged ≥80 years,diabetes,coronary artery lesion ≥2 branches,left main coronary ar-tery disease,history of myocardial infarction than the control group(P＜0.05,P＜0.01).Aged 80 years,diabetes,diseased branches ≥2,left main artery disease and history of myocardial infarc-tion were independent influencing factors of cardiogenic shock in elderly AMI patients(OR=2.280,95％CI:1.294-4.017,P=0.004;OR=2.326,95％CI:1.281-4.225,P=0.006;OR=3.868,95％CI:2.145-6.975,P=0.000;OR=3.587,95％CI:1.868-6.886,P=0.000;OR=4.040,95％CI:1.951-8.365,P=0.000).Based on these relevant risk factors,a prediction model was constructed.The AUC value of the model in the training set was 0.799(95％CI:0.736-0.862),while the value for the validation set was 0.737(95％CI:0.634-0.840).Hosmer-Lemeshow Goodness of Fit test showed the model had good reliability(x2=7.117,P=0.524).The in-hospital mortality rate was significantly higher in the cardiogenic shock group than the control group(12.12％vs 0.67％,P=0.000).Conclusion Cardiogenic shock can lead to poor prognosis in elderly AMI patients.Aged ≥80 years,diabetes,diseased branches ≥2,left main ar-tery disease and history of myocardial infarction are independent risk factors for cardiogenic shock.

【Objective】 To investigate cortical thickness changes in the face-head region of the primary motor cortex (PMC) and its effect on survival in amyotrophy lateral sclerosis (ALS) patients. 【Methods】 A retrospective analysis was performed on 105 ALS patients who underwent head MRI scan at the same time. The A4hf (face-head) region of PMC was used as the region of interest (ROI). According to clinical symptoms, patients were divided into two groups: bulbar involvement and non-bulbar involvement. The differences of clinical features and cortical thickness in ROI were analyzed. According to the symptoms of bulbar palsy, physical examination of nervous system and EMG of tongue muscle, the patients with bulbar palsy were divided into lower motor neuron (LMN), upper motor neuron (UMN) and LMN+UMN groups. The differences of bulbar subgroup score and ROI of cortical thickness were analyzed. Age at onset, body mass index, delayed time of diagnosis, bulbar subgroup score, and ROI cortical thickness were included in survival analysis. 【Results】 ① The ROI cortical thickness was significantly lower in bulbar involvement group than non-bulbar involvement group (-0.198±0.87 vs. 0.235±0.95, P=0.017). ② There were no significant differences in the bulbar subgroup scores or cortical thickness of ROI between LMN, UMN and LMN+UMN groups (P>0.05). ③ Survival analysis showed age of onset (HR=3.296, 95% CI:1.63-6.664, P=0.001), delayed time of diagnosis (HR=0.361, 95% CI:0.184-0.705, P=0.003), bulbar subgroup score (HR 0.389, 95% CI:0.174-0.868, P=0.021), and ZRE_ROI cortical thickness (HR=2.309, 95% CI:1.046-5.096, P=0.038) were independent influencing factors of ALS survival. 【Conclusion】 Cortical thickness in A4hf (face-head) region can more objectively reflect UMN signs of region bulbar. In addition to age of onset and delayed time of diagnosis, bulbar subgroup score and cortical thickness of face-head region are also independent influencing factors, and cortical thinning in face-head region is a protective factor for survival of ALS patients.

【Objective】 The involvement of upper motor neuron (UMN) degeneration is crucial to the diagnosis of amyotrophic lateral sclerosis (ALS). This study aimed to determine objective and sensitive UMN degeneration markers for an accurate and early diagnosis. 【Methods】 A total of 108 ALS patients and 90 age- and gender-matched control subjects were recruited from ALS Clinic of The First Affiliated Hospital of Xi’an Jiaotong University. The motor homunculus cortex thickness data in MRI were collected from all the participants. The clinical characteristics and UMN clinical examination of bulbar, cervical, thoracic and lumbosacral regions were collected from the ALS patients. 【Results】 Cortical thickness was significantly thinner in the ALS group than in the control group in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the global UMN positive group was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the UMN positive group in the corresponding region was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). 【Conclusion】 The thinning of the motor homunculus cortex can be used as an objective marker of UMN involvement in ALS patients in clinical practice.

Peri-implantitis is one of the most important biological complications in the field of oral implantology. Identifying the causative factors of peri-implant inflammation and osteolysis is crucial for the disease's prevention and treatment. The underlying risk factors and detailed pathogenesis of peri-implantitis remain to be elucidated. Titanium-based implants as the most widely used implant inevitably release titanium particles into the surrounding tissue. Notably, the concentration of titanium particles increases significantly at peri-implantitis sites, suggesting titanium particles as a potential risk factor for the condition. Previous studies have indicated that titanium particles can induce peripheral osteolysis and foster the development of aseptic osteoarthritis in orthopedic joint replacement. However, it remains unconfirmed whether this phenomenon also triggers inflammation and bone resorption in peri-implant tissues. This review summarizes the distribution of titanium particles around the implant, the potential roles in peri-implantitis and the prevalent prevention strategies, which expects to provide new directions for the study of the pathogenesis and treatment of peri-implantitis.
