The discussion on the connotation of children’s subjectivity is not only a response to the lack of children’s subjectivity at the current stage of health management, but also a reference for children’s medical science popularization. Based on the perspective of social critical theory, this study used empirical research methods to review the "Dream Medical College" project of Children’s Hospital of Fudan University. The current situation and influencing factors of health management experience of 1 520 children participating in the "Dream Medical College" project were analyzed. The study showed that 96.35% of 1 316 subjects had diagnosis and treatment experience in specialized hospitals, and the overall negative emotional performance was at a low level (0~12 points). There was significant correlation between diagnosis and treatment, invasive experience and children’s emotional performance (P<0.05). The study revealed that the diagnosis and treatment field is the main practice place of children’s health management, while the subjective of children with different diagnosis and experience perform significantly different. Children over 4 years old have better language anxiety than physical anxiety when receiving diagnosis and treatment. Although medical science popularization is an important practical form of children’s health management, it lacks the science popularization content of invasive diagnosis and treatment and emotional management, and creative popular science form is more suitable for children with long-term and frequent diagnosis and treatment experience.

Objective: To understand the trends in malnutrition among primary and middle school students of Han nationality in Hainan Province from 2005 to 2019, so as to provide a basis for improving nutrition intervention measures for children and adolescents. Methods: A sample of 32 949 Han nationality primary and middle school students aged 7-18 years old in Hainan Province were investigated in 2005, 2010, 2014 and 2019 based on national survey on student physical fitness and health. The Malnutrition Screening Standard of Schoolage Children and Adolescents was used to screen malnutrition. Statistical analysis was performed using the χ2 test and the χ2trend test. Results: In the four surveys conducted during 2005 to 2019, the prevalence of malnutrition among primary and middle school students were 22.12%, 18.80%, 15.89% and 9.56%, respectively, with an increase of -12.56% and an average annual increase of -5.82%. The decreasing trend of malnutrition by year was statistically significant (χ2trend=600.72, P<0.01), and the proportion of emaciation type was the highest (8.87%-20.15%). The detection rates of malnutrition among all students aged 7 to 18 showed a decreasing trend from 2005 to 2019 (χ2trend=56.44, 60.04, 61.48, 42.49, 51.81, 50.81, 72.86, 101.34, 86.38, 24.81, 17.72, 10.38, P<0.01). From 2005 to 2019, the detection rates of malnutrition in boys were higher than that of girls (in 4 surveys), and that in rural students from 2005 to 2014 of 3 surveys were higher than that in towns (χ2=92.07, 35.16, 25.29, 29.98; 64.35, 4.26, 6.32, P<0.05). Conclusions The malnutrition of Han nationality primary and middle school students aged 7-18 years in Hainan Province show a trend of improvement year by year from 2005 to 2019, despite the overall high detection rate. Wasting is the most common type of malnutrition. The epidemic of malnutrition varies by age, sex and areas. Further targeted measures should be taken to strengthen intervention in the diet of primary and middle school students, to improve the nutritional status of children and adolescents.

Aim To explore the correlation between carotid atherosclerosis(CAS)and neutrophil/lymphocyte ratio(NLR)in patients with early morning hypertension,and to construct a line chart model to predict the risk of CAS in patients with hypertension in the morning.Methods 255 patients with early morning hypertension hospitalized in the Affiliated Hospital of Chengde Medical College from October 2019 to November 2022 were collected,and their basic data,blood routine and blood biochemical indexes were collected.All selected patients need to improve 24-hour ambulatory blood pressure monitoring and carotid artery color ultrasound detection.According to the presence or absence of CAS,all selected patients were divided into morning hypertension with CAS group(n=197)and morning hypertension without CAS group(n=58).Multivariate Logistic regression analysis was used to explore the risk factors of early morning hypertension with CAS,and to construct and verify an individual line chart model to predict the risk of early morning hypertension pa-tients with CAS.Results The age,NLR,neutrophils(NE),monocytes(MO),white blood cell(WBC),total cho-lesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDLC)increased in the early morning hyperten-sion with CAS group compared with those in the morning hypertension group without CAS,while the HDLC decreased(P＜0.05).The results of multivariate Logistic regression analysis showed that the age,NLR and TC were higher in the early morning hypertension with CAS group than those in the early morning hypertension without CAS group,while HDLC was lower;Age,NLR and TC were independent risk factors of early morning hypertension with CAS,while HDLC was inde-pendent protective factors of morning hypertension with CAS.Based on the results of multivariate Logistic regression anal-ysis,an individualized line chart model for predicting early morning hypertension with CAS was constructed.The area un-der the ROC curve of the line chart model was 0.853(95％CI:0.802-0.904,P＜0.01).The result of Hosmer Leme-show fit test was x2=1.665(P＞0.05).Conclusions There was a positive correlation between NLR and morning hy-pertension with CAS,and NLR was an independent risk factor for morning hypertension with CAS.The individualized line chart model based on age,NLR,TC and HDLC can effectively predict the risk of hypertension with CAS in the early morn-ing,which provides a theoretical basis for early detection and prevention of atherosclerosis.

Objective: To analyze the trends of overweight and obesity in children and adolescents aged 7-18 in Hainan Province from 2005 to 2019, in order to provide a scientific basis for prevention strategies. Methods: Data were sourced from a total of 42 811 students in Hainan Province in 2005, 2010, 2014 and 2019 for physical fitness and health investigation, according to the criteria of Screening for Overweight and Obesity among School aged Children and Adolescents. The linear trend of overweight and obesity was compared by using the χ 2 test and χ 2 trend test, and with 2005 as the base period, the dynamic analysis was conducted to compare the growth and development rates of overweight and obesity. Results: The detection rates of overweight in children and adolescents aged 7-18 in Hainan Province were 4.7%, 5.1%, 6.7% and 10.8% in 2005, 2010, 2014 and 2019, respectively, while the detection rates of obesity were 2.7%, 2.4%, 2.5% and 6.8%, which showed an overall upward trend by year ( χ 2 trend =370.57 , 313.55, P <0.01). All differences in overweight and obesity detection rates across gender, ethnicity, and age groups were statistically significant for each year ( χ 2=9.56-290.95, P <0.01). And the detection rates of overweight and obesity increased linearly over year in different characteristic groups ( χ 2 trend =29.92-280.11, P <0.01). The annual growth rate of overweight detection rate was higher for girls (6.4%) than for boys (6.1%), higher for ethnic minorities (7.1%) than for Han (5.7%), and higher for the 16- 18 age group (8.4%) than for the 7-9 (3.6%), 10-12 (6.2%), and 13-15 age groups (7.7%). And the annual growth rate of obesity detection rate was higher for boys (8.1%) than for girls ( 5.7% ), higher for ethnic minorities (7.1%) than for Han ( 6.8% ), and higher for the 16-18 age group (77.2%) than for the 7-9 (2.8%), 10-12 (8.2%), and 13-15 (18.7%) age groups. Conclusions The overall prevalence of overweight and obesity among children and adolescents aged 7-18 in Hainan Province continues to increase from 2005 to 2019, with differences in genders, ethnic and ages. Interventions should be implemented to reduce the incidence of overweight obesity in children and adolescents.

Objective:To evaluate the efficacy and safety of dupilumab in the treatment of prurigo nodularis (PN) in the real world.Methods:PN patients who were subcutaneously injected with dupilumab for over 12 weeks were collected from the China Type Ⅱ Inflammatory Skin Disease Clinical Research and Standardized Diagnosis and Treatment Project Database from June 2021 to October 2022. Their clinical data were retrospectively analyzed, which included demographic data, and changes in pruritus numeric rating scale (NRS), investigator global assessment for PN-Stage (IGA PN-S), dermatology life quality index (DLQI) and hospital anxiety and depression scale (HADS) scores before and after treatment. Differences in scores before and after treatment, as well as in efficacy between patients with and without a history of atopic diseases, were analyzed using Wilcoxon signed-rank test, paired t-test or chi-square test. Results:A total of 66 PN patients were collected, including 42 males and 24 females, and they were aged 8 to 89 (44.12 ± 24.17) years. Thirty-six patients had a history of atopic diseases, and 27 had a family history of atopic diseases. After 12-week treatment with dupilumab, the pruritus NRS, IGA PN-S and DLQI scores in the 66 patients significantly decreased from the baseline scores (7.00 [5.00, 8.00], 3.00 [3.00, 4.00], 12.00 [7.75, 20.25], respectively) to 3.00 [2.00, 4.25], 2.00 [2.00, 3.00], 5.00 [1.75, 8.25], respectively (all P < 0.001). Among the 66 patients, 39 continued the regular treatment with dupilumab after 12 weeks and were followed up to 16 weeks; their pruritus NRS and IGA PN-S scores at week 16 further decreased compared with those at week 12 (both P < 0.05). There were no significant differences in the proportion of patients showing an improvement of ≥ 4 points in the NRS score or the proportion of patients achieving IGA 0/1 at week 12 between the patients with history of atopic diseases and those without (both P > 0.05). Before treatment, 32 PN patients were accompanied by mild to severe anxiety and/or depression; after 12-week treatment, the HADS-A scores in the 28 patients with anxiety (HADS-A scores > 7 points) and the HADS-D scores in the 20 patients with depression (HADS-D scores > 7 points) significantly decreased compared with their baseline scores (both P < 0.001) ; 18 (56.52%) patients achieved remission in anxiety and depression (both HADS-A and HADS-D scores < 7 points). Among the 66 PN patients, there were 13 minor patients, including 7 males and 6 females, and they were aged 8 to 17 (13.77 ± 3.09) years; after 12-week treatment, their pruritus NRS, IGA PN-S, and DLQI scores significantly decreased compared with the corresponding baseline scores (all P < 0.05) ; 8 minor patients continued dupilumab treatment for 16 weeks, with a further decrease in the IGA PN-S score compared with that at week 12 ( P < 0.05), but without significant differences between the pruritus NRS and DLQI scores at week 16 and those at week 12 (both P > 0.05). Adverse reactions were observed in 7 adult patients, including eye pruritus, local injection reactions, and systemic erythema accompanied by pruritus on the day of injection. No adverse reactions were reported in minor patients. Conclusion:In the real world, dupilumab could markedly alleviate pruritus, skin lesions, anxiety and depression symptoms in PN, improve the quality of life, and exhibited a good safety profile.

BACKGROUND: Pathological cardiac hypertrophy is one of the main activators of heart failure. Currently, no drug can completely reverse or inhibit the development of pathological cardiac hypertrophy. To this end, we proposed a silicate ion therapy based on extract derived from calcium silicate (CS) bioceramics for the treatment of angiotensin II (Ang II) induced cardiac hypertrophy. METHODS: In this study, the Ang II induced cardiac hypertrophy mouse model was established, and the silicate ion extract was injected to mice intravenously. The cardiac function was evaluated by using a high-resolution Vevo 3100 small animal ultrasound imaging system. Wheat germ Agglutinin, Fluo4-AM staining and immunofluorescent staining was conducted to assess the cardiac hypertrophy, intracellular calcium and angiogenesis of heart tissue, respectively. RESULTS: The in vitro results showed that silicate ions could inhibit the cell size of cardiomyocytes, reduce cardiac hypertrophic gene expression, including atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and b-myosin heavy chain (b-MHC), decrease the content of intracellular calcium induced by Ang II. In vivo experiments in mice confirmed that intravenous injection of silicate ions could remarkably inhibit the cardiac hypertrophy and promote the formation of capillaries, further alleviating Ang II-induced cardiac function disorder. CONCLUSION This study demonstrated that the released silicate ions from CS possessed potential value as a novel therapeutic strategy of pathological cardiac hypertrophy, which provided a new insight for clinical trials.

In the subsequent improvement, the software and hardware construction should be comprehensively improved to further improve the prediction accuracy.

Objective:To analyze the incidence and prognosis of epilepsy in frontotemporal lobe glioma.Methods:The clinical data of 208 patients with frontotemporal lobe gliomas in Sanbo Brain Hospital Capital Medical University from 2019 to 2021 were analyzed retrospectively. According to the 2016 World Health Organization (WHO) classification of tumors of the central nervous system, the incidence of epilepsy, Modified Rankin Scale (MRS) score, and Engel Outcome Scale of patients with different grades of tumors were calculated.Results:Among all the patients with frontotemporal lobe gliomas, there was more males than females, and it was more common in the 40 -59 age group. The incidence of epilepsy associated with WHO grade Ⅰand Ⅱ glioma was 100.0% (33/33) and 60.9% (14/23), respectively, while that of WHO grade Ⅳ glioma was 19.0%(19/100). The average follow-up time was (22 ± 9) months. During the follow-up period, the incidence of WHO grade Ⅰ, Ⅱ and Ⅲ glioma-related epilepsy decreased significantly. There was no significant difference in the incidence of glioma-related epilepsy between the total and subtotal resection groups ( P>0.05). There was no statistical correlation between the side of tumor occurrence and the occurrence of epilepsy ( P>0.05), also between the gene phenotype and the occurrence of epilepsy ( P>0.05). There was no significant difference in the Engel Outcome Scale among different grades of gliomas ( P>0.05). The prognosis of patients with Engel Outcome Scale Class 1 was significantly better than that of other grades. Conclusions:The incidence of glioma-related epilepsy is negatively correlated with tumor grade. Age and sex are risk factors for glioma-related epilepsy. The incidence of postoperative epilepsy in patients with low grade glioma is significantly lower than that in patients with high grade glioma, and the prognosis is better. However, there is no significant difference in the Engel Outcome Scale among different grades of gliomas.

Objective:To investigate the effect and role of the hepatitis B virus (HBV) on the expression of inhibin (PHB) in the proliferation and survival of hepatocellular carcinoma (HCC) cells.Methods:The expression of PHB in 13 pairs of HBV-infected livers, normal livers and HepG2.2.15 and HepG2 cells was detected by real-time fluorescent quantitative PCR and Western blot. Liver tissues were collected from seven patients with chronic hepatitis B before and after antiviral (tenofovir) treatment, and the expression of PHB was detected by RT-PCR and Western blot. HepG2.2.15 cells were transfected with Pcmv6-AC-GFP-PHB, and control vectors were collected. DNA content was analyzed by flow cytometry. The proliferation level of each cell group was detected using the EdU cell proliferation assay. HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB and the control vector were cultured in serum-free medium for 6 days. Apoptosis was measured at the indicated time points using fluorescence-activated cell sorting (FACS)-based Annexin-V/PI double staining.Results:Compared with normal liver tissue, the expression of PHB in HBV-infected liver tissue was down-regulated ( P < 0.01). Compared with HepG2 cells, the expression of PHB in HepG2.2.15 cells was significantly decreased ( P < 0.01). The expression level of PHB in liver tissue after antiviral treatment (tenofovir) was significantly higher than that before treatment ( P < 0.01). Compared with the control vector, the proliferation rate of HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB was significantly lower than that of the control vector, and the apoptosis rate of HepG2.2.15 cells transfected with the Pcmv6-AC-GFP-PHB vector was significantly higher than the control vector ( P < 0.01). Conclusion:HBV down-regulates the expression of inhibin to promote the proliferation and survival of hepatocellular carcinoma cells.
