Objective To investigate correlation between the expression level of multiple cytokine levels in neonatal umbilical cord plasma and early-onset sepsis for screening out the cytokines with good diagnostic value for early-onset neonatal sepsis(EONS).Methods Full-term neonates and preterm neonates(Gestational age ≥ 32 weeks)of 310 cases between September 2021 and June 2023 were selected as study subjects.According to clinical signs,laboratory results and blood culture,these subjects were divided into 3 groups:control group without sepsis,EONS blood culture positive group and EONS blood culture negative group.Umbilical cord blood plasma of all subjects was collected within 72 hours after birth.The expression levels of cytokines IL-2,IL-4,IL-6,IL-9,IL-10,IL-21,IFN-γ and TNF-α were determined,and cytokines with high expression levels(high correlation)were screened out.Receiver operating characteristic(ROC)curve was used to analyze the specificity and sensitivity of the selected cytokines in the diagnosis of neonatal early-onset sepsis.Results Among the 8 cytokines mentioned above,the concentrations of IL-6,IL-9 and IL-21 in cord blood plasma of neonatal early-onset sepsis positive blood culture patients(392.6±258.7pg/ml,11.9±7.5pg/ml,29.1±16.8 pg/ml)and negative blood culture patients(353.8±244.5pg/ml,10.4±6.3pg/ml,27.7±19.2pg/ml)were higher than those of the control group(34.9±25.1pg/ml,5.9±4.5pg/ml,10.8±10.1 pg/ml),with significant differences(t=23.961,20.732;15.174,17.824;22.466,21.193,all P＜0.01),and the increase of IL-6 concentration was the most obvious.ROC curve analysis(the cut-off values of IL-6,IL-9 and IL-21:123.0 pg/ml,3.60 pg/ml,6.00 pg/ml,respectively)showed that the areas under the ROC curve for IL-6,IL-9 and IL-21 alone detection were 0.876(95％CI:0.786～0.955),0.782(95％CI:0.667～0.875)and 0.825(95％CI:0.737～0.913),respectively.The area under the ROC curve for the combined detection of IL-6,IL-9 and IL-21 was 0.930(95％CI:0.875～0.997).The combined detection of IL-6,IL-9 and IL-21 improved the specificity and sensitivity of the test than IL-6,IL-9 and IL-21 alone detection,and the differences were statistically significant(Z=2.137,2.391,2.257,all P＜0.05).There was no significant difference in cytokine expression between positive blood culture and negative blood culture neonates with early-onset sepsis(t=0.276～3.377,all P＞0.05).Conclusion The cytokines expression of IL-6,IL-9 and IL-21 in neonatal umbilical cord plasma of neonatal early-onset sepsis were increased.Combined detection of IL-6,IL-9 and IL-21 has good diagnostic value for early-onset neonatal sepsis.

Abstract Health literate schools (HeLit-Schools) play a significant role in fostering students health literacy. The paper elucidates the background and conceptual connotations of HeLit-Schools, and analyzes how HeLit-Schools effectively integrate and enhance the health literacy of schools in three aspects: philosophy and core drivers, strategy and method implementation, as well as evaluation mechanisms and standard setting. Furthermore, the paper explores the implications of foreign HeLit-Schools research and practice for China under the context of "Healthy China" construction, as well as the key strategies for Chinese schools in the implementation of HeLit-Schools, aiming to provide a new perspective and theoretical support for Chinese schools to practice the "Healthy China initiative" and strengthen school construction from the perspective of health literacy.

Abstract Enhancing the health literacy of the entire population is a prerequisite for improving the health of the entire population, and since the health attitudes and behaviors formed during childhood and adolescence have a profound impact on the health patterns of adulthood, the enhancement of health literacy of children and adolescents is of particular importance. As the main place for children and adolescents to receive education, schools should better fulfil the function of education and promotion of health literacy. China has been carrying out the pilot and promotion of health promoting schools (HPS) since 1995, and is currently in the stage of comprehensive improvement of HPS construction. This paper introduces the background and characteristics of Health-Literate Schools (HeLit-Schools) in foreign countries and compares them with HPS in China, drawing on the advantages of HeLit-Schools to provide a new idea and a new way of thinking for the construction of HPS in China and for the practice of the "Healthy China Initiative".

Abstract As dietary issues of children and adolescents become increasingly complex, the assessment of food literacy (FL) is increasingly importance. FL involves a comprehensive cognition and practical ability concerning food among children, playing a key role in fostering healthy eating habits and improving health levels. The article explores the definition and connotations of FL, and introduces eight FL assessment tools in terms of theoretical foundations, dimensions, assessment methods, and their reliability and validity. Moreover, it provides a comparative analysis of these tools by examining their dimensional design, evaluation indicators, strengths, and weaknesses, as well as their applicable subjects and scenarios, aiming to offer references for implementing relevant policies and developing more comprehensive and effective FL assessment tools.

OBJECTIVE: To investigate whether dynamic monitoring of citrulline (Cit) has guiding value for early enteral nutrition (EN) in patients with severe gastrointestinal injury. METHODS: A observational study was conducted. A total of 76 patients with severe gastrointestinal injury admitted to different intensive care units of Suzhou Hospital Affiliated to Nanjing Medical University from February 2021 to June 2022 were enrolled. Early EN was performed in 24-48 hours after admission as recommended by the guidelines. Those who did not terminate EN after 7 days were enrolled in the early EN success group, and those who terminated EN within 7 days due to persistent feeding intolerance or deterioration of general condition were enrolled in the early EN failure group. There was no intervention during the treatment. Serum Cit levels were measured by mass spectrometry at admission, before EN starting and EN 24 hours, respectively, and the changes in Cit within EN 24 hours (ΔCit) were calculated (ΔCit = EN 24-hour Cit-Cit before EN starting). Receiver operator characteristic curve (ROC curve) was plotted to investigate the predictive value of ΔCit for early EN failure, and the optimal predictive value was calculated. Multivariate unconditional Logistic regression was used to analyze the independent risk factors for early EN failure and death at 28 days. RESULTS: Seventy-six patients were enrolled in the final analysis, of which 40 succeeded in early EN and 36 failed. There were significant differences in age, main diagnosis, acute physiology and chronic health evaluation II (APACHE II) score at admission, blood lactic acid (Lac) before EN initiation and ΔCit between the two groups. Multivariate Logistic regression analysis showed that age [odds ratio (OR) = 0.929, 95% confidence interval (95%CI) was 0.874-0.988, P = 0.018], ΔCit (OR = 2.026, 95%CI was 1.322-3.114, P = 0.001) and increased feeding rate within 48 hours (OR = 13.719, 95%CI was 1.795-104.851, P = 0.012) were independent risk factors for early EN failure in patients with severe gastrointestinal injury. ROC curve analysis showed that ΔCit had a good predictive value for early EN failure in patients with severe gastrointestinal injury [area under the ROC curve (AUC) = 0.787, 95%CI was 0.686-0.887, P < 0.001], and the optimal predictive value of ΔCit was 0.74 μmol/L (sensitivity was 65.0%, specificity was 75.0%). Combined with the optimal predictive value of ΔCit, "overfeeding" was defined as ΔCit < 0.74 μmol/L and increased feeding within 48 hours. Multivariate Logistic regression analysis showed that age (OR = 0.825, 95%CI was 0.732-0.930, P = 0.002), APACHE II score (OR = 0.696, 95%CI was 0.518-0.936, P = 0.017) and early EN failure (OR = 181.803, 95%CI was 3.916-8 439.606, P = 0.008) were independent risk factors for 28-day death in patients with severe gastrointestinal injury. The new variable "overfeeding" was also associated with an increased risk of death at 28 days (OR = 27.816, 95%CI was 1.023-755.996, P = 0.048). CONCLUSIONS Dynamic monitoring of Cit has guiding value for early EN in patients with severe gastrointestinal injury.

Objective:To analyze the clinical features and magnetic resonance imaging of non-malignant patients assigned to Prostate Imaging Reporting And Data System (PI-RADS) 5 score.Methods:We performed a retrospective review of 289 patients who underwent magnetic resonance ultrasound targeted combined system biopsy with PI-RADS 5 lesions in the First Affiliated Hospital of Nanjing Medical University between May 2019 and July 2021. The median age 72 (66, 77)years, median body mass index 24.4(22.3, 27.1)kg/m 2, median prostate volume (PV) 37.39(29.39, 48.86) ml, median PSA 22.24(10.91, 62.69) ng/ml, and median PSAD 0.53(0.30, 1.52)ng/ml 2 were recorded. According to the biopsy pathological results, all patients were divided into benign lesion group and prostate cancer group. PSA, PSAD, PV, and apparent diffusion coefficient (ADC) values were compared, and magnetic resonance imaging and clinical characteristics of patients with biopsy benign lesions were analyzed. Results:There were 11 cases (3.8%) with benign lesion and 278 cases (96.2%) with prostate cancer. The characters of 11 negative biopsy cases were displayed as follows: median age 69(66, 79)years, median body mass index 22.0(21.0, 25.5)kg/m 2, median PV 62.90(38.48, 71.96)ml, median PSA 5.55(2.99, 20.52)ng/ml, median PSAD 0.16(0.07, 0.24) ng/ml 2, median ADC 714.47(701.91, 801.26)×10 -6 mm 2/s, abnormal digital rectal and amination in 5 cases, smoking in 7 cases, and alcohol consumption in 4 cases. The median PV [62.90(38.48, 71.96) vs. 37.21(29.22, 47.82)ml, P<0.01], the PSA value [5.55(2.99, 20.52) vs. 23.53(11.14, 65.98)ng/ml, P<0.01], and the PSAD value [0.16(0.07, 0.24) vs. 0.58(0.31, 1.57)ng/ml 2, P<0.01] were significantly different between benign condition group and prostate carcinoma group. Benign condition group included 5 chronic prostatitis, 2 acute prostatitis (1 with focal adenocarcinoma), 2 granulomatous inflammation, and 2 tuberculous granulomatous inflammation. In 7 benign cases, PSA was less than 10 ng/ml, combined with frequent urination, urgency of urination and incontinence were founded. In 8 benign cases, the area of lesion was more than 50% of the total prostate area in the axial position and the imaging of magnetic resonance were diffused, with regular shape and uniform signal. The imaging of symmetrical distribution was in 6 cases. Conclusions:The benign condition with PI-RADS 5 lesions included chronic prostatitis, acute prostatitis, granulomatous inflammation and tuberculous granulomatous inflammation, among which prostatitis was the most common cause. The PSA value were less than 10 ng/ml in most benign cases, with symptoms such as frequent urination, urgency of urination and incontinence. The imaging of magnetic resonance were diffused, symmetrically distributed, with regular shape and uniform signal.

OBJECTIVE：To study the effects of augmented renal clearance （ARC）on blood trough concentration of patients receiving high-dose regimen of teicoplanin. METHODS ：Patients who received high-dose regimen of teicoplanin in the ICU were prospectively collected from the Affiliated Suzhou Hospital of Nanjing Medical University/Suzhou Municipal Hospital during Jul. 2018-Jun. 2020. They were divided into ARC group and normal renal function group according to corrected creatinine clearance. The dosage regimen of teicoplanin in the two groups were loading dose of 600 mg，q12 h×3 doses，maintenance dose of 6-10 mg/kg，qd，and the dosage was adjusted in combination with creatinine clearance rate and blood trough concentration. The trough concentration of blood samples which were collected 30 min before the 4th and 8th-10th dosage of teicoplanin were determined by HPLC. Trough concentration ，clinical efficacy ，Gram-positive bacterial clearance rate and the occurrence of ADR were compared between 2 groups. RESULTS ：A total of 56 patients were included and divided into ARC group （18 cases）and normal renal function group （38 cases）. ARC group had younger age （P＜0.001）and lower serum albumin level （P＝0.025）than normal renal function group. The trough concentrations before administration of the 4th and 8th-10th dosage in ARC group were lower than normal renal function group （P＝0.034；P＝0.035）. The trough concentrations in the ARC group and normal renal function group before 8th-10th dosage were all higher than 30 min before the 4th dosage （P＝0.003；P＜0.001）. The clinical efficacy rate and the clearance rate of Gram-positive bacteria in ARC group were 77.8％ and 76.2％，which were lower than those of the normal renal function group ，but there was no statistical difference （P＝0.195；P＝0.223）. There was no liver function damage ，hemocytopenia and allergic reaction in both groups ，but in the normal renal function group ，the causal relationship between acute renal damage and teicoplanin was assessed as “very likely ”in one patient. CONCLUSIONS ：ARC patients are younger ，most of them have hypoproteinemia，and the blood trough concentrations of teicoplanin in high-dose regimen are significantly lower than those of normal renal function patients. For critical ill ARC patients ，it is advisable to increase the loading dose of teicoplanin to make the trough concentration reach the target concentration range quickly.
