Objective To evaluate skin barrier function in children with atopic dermatitis (AD) as well as healthy children from two communities in Shanghai and to assess the relationship between skin barrier function and AD severity.Methods Totally,169 children with AD and 142 healthy children aged 3-12 years were recruited from two communities (Changning Xining community and Jiading Juyuan community) in Shanghai,China.Transepidermal water loss (TEWL) and stratum corneum hydration were measured in normal appearing nonlesional skin at four body sites (dorsal and volar forearm,cheek and anterior shin) of the patients,as well as in normal skin at the same sites of the controls.AD severity was evaluated by using the severity scoring of atopic dermatitis (SCORAD) index.Results Compared with the healthy children,the patients with AD showed higher TEWL value at all of the four body sites (all P ＜ 0.05),but lower water content in stratum corneum at dorsal forearm and anterior shin (both P ＜ 0.05).In patients with AD,the SCORAD index was positively correlated with mean TEWL value,but negatively correlated with the mean water content in stratum corneum.Conclusion Skin barrier function may serve as an index for evaluating the severity of AD.

Objective To evaluate the diagnostic value of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in combination with flow cytometry (FCM) in lymphoma.Methods From January 2011 to December 2011,the cases of suspicious lymphoma with EUS-FNA examination at Shanghai Ruijin Hospital were retrospectively analyzed.The final diagnosis was according to pathological diagnosis of specimen from the surgery and follow up results.The sensitivity,specificity and accuracy of EUS-FNA combined with FCM in lymphoma diagnosis were initially analyzed.Results A total of 14 suspicious lymphoma patients were collected,eight cases were diagnosed as lymphoma by pathological examination of specimen from the surgery or.tissue from aspiration,four cases were non-lymphoma lesions and two cases still had no final diagnosis.The sensitivity and specificity of FCM alone in lymphoma diagnosis were 4/8 and 4/4 respectively.Six cases of lymphoma were detected by EUS-FNA with FCM.The sensitivity,specificity and accuracy of EUS FNA combined with FCM were 6/8,6/6 and 10/12 respectively.Conclusion EUS-FNA combined with FCM has better diagnostic value in lymphoma,especially for gastrointestinal lymphoma and those surrounding deep lesions.

Abstract The processs of female Osteoporosis and its prevention by Physical activity were simulated using anisotropic bone remodelling model with mechanostat combining with finite element method. The results show that bone mass declines slowly at the beginning, bone loss accelerates in postmenopause and bone mass declines 25. 84%-28.63% at the age of 60 and 38.50%-40.44% at the age of 80. Bone mass increases 3.05%-10.26% by an increase of 10%-20% in physical activity. The above results are consistent with clinical observations,which proves that declination of mechanical usage is the primary factor leading to osteoporosis, menopause quickens the process of female osteoporosis, physical activity can decelerate it.

Objective To explore the relationship among social support, postpartum depression and quality of life of puerperal women. Methods A total of 348 puerperal women were investigated with Postnatal Social Support Questionnaire,Edinburgh Postnatal Depression Scale (EPDS) and WHO Quality of Life-BREF (WHOQOL-BREF). Results Pearson correlation analysis showed that there was a significant positive correlation between social support and the quality of life (r=0.483, P < 0.01), and a significant negative correlation to postpartum depression (r=-0.243, P < 0.01),and a significant negative correlation between postpartum depression and quality of life (r=-0.408, P<0.01). Intermediary effect of postpartum depression was tested. Conclusions A good social support system is benefit to improve depression scores for EPDS, and promote the life quality in puerperal women.

Objective:pH low insertion peptide (pHLIP)-variant 7 (var7)-fluorescein isothiocyanate (FITC) was used to explore an accurate imaging tool that targeted burn wounds to better perform burn debridement.Methods:Twelve rat models of burn wound were established and pHLIP-var7-FITC with different concentrations (0.5, 1.5 and 2.0 mg/ml) were injected from the rat tail vein for in vivo fluorescence imaging. By determining the concentration of fluorescent conjugates to the burn wound, the scope of wound injury necrosis was judged by combining pathological sections, and its residue and toxicity in important organs such as heart, liver, kidneys, and brain were detected. The Kruskal-Wallis rank sum test, Bonferroni correction method and one-way analysis of variance were used for data analysis. Results:Within 24 h, the fluorescence photons per unit area of the burn wound in the group of 0.5 mg/ml, 1.5 mg/ml and 2.0 mg/ml were 1.49(1.31, 1.65), 2.46(1.88, 2.68), 2.77 (1.94, 3.10)×10 7 p·s -1·cm -2·Sr -1, with significant differences in the overall distribution of fluorescence photons ( H=73.55, P<0.001). The fluorescence intensity was stronger in the group with higher concentration, but with no significant difference in the number of fluorescence photons between the group of 1.5 mg/ml and 2.0 mg/ml ( P=0.263, Bonferroni correction method). At 14 time points (0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 12, 24 h), there was no significant difference in the overall mean of fluorescence photons ( F=1.04, P=0.419), and the tissue with burn necrosis seen in tissue sections was highly consistent with the fluorescence imaging region. There was no obvious fluorescence residue in the heart, liver, kidney and brain sections. Conclusion:In superficial second-degree burn tissue, pHLIP-var7-FITC can accurately target and gather on the burn wound within 24 h, showing a clear boundary between burn tissue and normal tissue, which can assist clinical surgical debridement to determine the extent of injury.

Objective: To construct and determine the weight of Index System for Assessing Parent s Ability on Child Injury Prevention, and to provide the basis for childhood injury intervention in family. Methods: Twenty four experts majored in related fields were invited to participate in Delphi consultation. The final index system was constructed according to the consulting results and the weight of primary and secondary indicators were calculated. Results: The final index system consisted of 5 subscales corresponding to 5 age groups: 0,1-2,3-5,6-11 and 12-17 years old. Each scale included 4 primary indicators and 11 secondary indicators. The weight of primary indicators obtained by analytic hierarchy process is 0.28 for "environment", 0.16 for "product", 0.31 for "behaviors and skills", and 0.25 for "psychology". The highest weight of secondary indicators for "environment", "product" and "behaviors and skills" was "water area", while the top secondary indicators for "psychology" included "parental style""emotional control" "family atmosphere", with all indicators weighted higher than 0.2. Conclusion The Index System for Assessing Parent s Ability on Child Injury Prevention by Delphi consultation is comprehensive in content, and with the focus on parental behaviors and skills on injury prevention.

Objective:To construct and test the reliability and validity of an assessment scale for self-management of patients with dry eye, so as to help patients establish dry eye related health behaviors.Methods:Based on the knowledge attitude and practice theory, the initial scale was constructed on the basis of literature review and qualitative interview, and revised through Delphi expert consultation and expert argumentation. After the preliminary investigation, 211 dry eye patients treated in the dry eye nursing outpatient department of Beijing Tongren Hospital from August 2023 to January 2024 were selected by convenience sampling method for questionnaire investigation to test the reliability and validity of the scale.Results:Among 211 dry eye patients, there were 58 males and 153 females, aged (39.31 ± 12.81) years old. The scale of self-management of patients with dry eye included 27 items in 3 dimensions: knowledge, attitude and behavior. The authority coefficient of the two rounds of expert consultation was 0.86, and the Kendall coordination index increased from 0.175 to 0.223 (both P < 0.01). The cumulative variance contribution rates of the three dimensions were 41.843%, 54.219% and 44.273%, respectively. The Cronbach α coefficient of the scale was 0.787, and the Spearman-Brown coefficient was 0.641. Conclusions:The scale of self-management of patients with dry eye has good reliability and validity and can be used in the assessment of dry eye patients to provide a reference basis for targeted guidance and intervention.

Objective:To investigate the clinical features of pediatric patients with intracranial primary non-germinomatous germ cell tumors (NGGCT) and evaluate the treatment outcomes and prognostic factors of NGGCT.Methods:Clinical data of 40 children with NGGCT who were treated with radiotherapy (RT) at our department between November 2008 and June 2019 were retrospectively analyzed. Ninety percent of them received craniospinal irradiation (CSI). All children received platinum-based chemotherapy. Survival analysis was conducted using the Kaplan-Meier estimate. The prognostic factors were analyzed by log-rank test.Results:The primary sites were pineal gland, sellar / suprasellar region and basal ganglia. The median age of onset was 108 months (20-204 months). The median follow-up time was 33 months (8-131 months), and the 3-year and 5-year overall survival (OS) rates were 82.0%. The 3-year and 5-year progression-free survival (PFS) rates were 78.6% and 73.0%. Univariate analysis showed that increased alpha-fetoprotein (AFP) ( P=0.02), age at first diagnosis>10 years ( P=0.006), metastasis at first diagnosis ( P<0.001), and the pathological type (choriocarcinoma, yolk sac tumor and / or embryonal carcinoma) ( P=0.036) were independent adverse prognostic factors. Conclusions:Increased AFP, age>10 years at first diagnosis, tumor metastasis and pathological type were independent adverse prognostic factors of NGGCT. The overall prognosis of NGGCT children is worse than that of their counterparts with germinoma, and multidisciplinary intensive therapy is needed to improve survival.

Objective: To investigate child injury prevention practice and associated factors among parents of primary school students. Methods: Parents of 2 577 students were selected from three primary schools in three administrative regions of Shanghai by multi stage sampling method between May and June in 2021. Questionnaire survey was administered to parents based on the Index System for Assessing Parent s Ability on Child Injury Prevention, which was developed previously by the present research group. Results were converted into standardized scores for descriptive analysis, and the original scores were analyzed by multiple linear regression model. Results: The standardized scores of parents on environment safety, product safety, behaviors and skills and psychological safety were (0.91±0.08)(0.93±0.08)(0.97±0.04)(0.95±0.05), respectively. The standardized score of general ability was (0.95±0.04). The standardized scores on knowledge, attitude and practice of injury prevention were (0.99±0.03)( 0.97± 0.05)(0.89±0.10), respectively. Mothers performances were generally better than fathers . Parents with higher education performed better than those with lower education. Parents with "being a parent" in mind performed better on child injury prevention. Conclusion There is a gap between practice with the knowledge as well as attitude towards child injury prevention among parents of primary school students. Parenting role, educational background and parental awareness of the importance of parental role are primary factors that affect child injury prevention practice.
